Wilson, Ray Sled, Renton Water Utility Memorandum From: Andrew Hill, Greg Pierson, HDR Project: Renton Well 5A Pre -Design Date: 23-Feb-2007 Re: Chlorine Evaluation 1.0 Overview and Purpose Job No: 51403 This technical memorandum has been prepared as part of Task 2-300 of the Renton Well 5A Water Treatment Improvements Project. The purpose of this memorandum is to provide an overview and comparative evaluation of two types of chlorination systems that are being considered for the new Well 5A treatment facility. This evaluation is intended to provide enough information to assist the City of Renton (City) in selecting the preferred chlorination method. As outlined in the project scope, the following two chlorination methods are being considered: Method 1: Commercial liquid hypochlorite (12.5% strength by weight) Method 2: On -site h.ypochlorite generation (0.8% strength by weight) The following general assumptions were made as part of this memorandum: O The selected treatment grain for the Well 5A facility will utilize the same approach as that at the Maplewood Water Treatment Facility. During operation, chlorine would be fed continuously ahead of the greensand filters. Booster chlorination would be applied at the end of the contact basin as needed to meet finished water quality goals. O Gas chlorination will not be used at the new Well 5A facility; therefore, it is not considered as part of this evaluation. O The chlorine storage and feed system components will be housed in a new treatment building. O All mechanical equipment used for the chlorine system will be new; i.e., none of the chlorine - related equipment from the existing facility will be salvaged for this project. O The applicable code requirements include the 2003 International Building Code (IBC) and the 2006 International Fire Code (IFC). This technical memorandum is organized as follows: Section 2 provides a brief process description of each of the two chlorination methods, along with general facility, equipment, and operations and maintenance (O&M) requirements; Section 3 provides preliminary design criteria used to support further evaluation; Section 4 provides planning -level capital, O&M, and life -cycle cost estimates; Section 5 summarizes information from the previous sections and provides a comparison of the two methods; and Section 6 provides a recommendation for the chlorination method. Well 5A Chlorine Evaluation City of Renton Project Number 51403 2.0 Chlorination Alternatives This section provides an overview of the two chlorination methods under consideration, while a more detailed analysis and comparison of the two methods is provided in later sections. 2.1 Commercial Liquid Hypochlorite Process Description. The application of commercial liquid hypochlorite (12.5% strength) would involve a relatively simple storage and feed system. The hypochlorite solution would be stored in tanks/totes within a secondary containment area and injected into the water supply with metering pumps. The solution could be delivered either in a tanker truck (i.e., bulk delivery) or supplied in exchangeable totes (250 to 300 gallon capacity each), with the preferred method driven in large part based on the storage requirements. In either case, a commercial vendor would be contracted to supply the chlorine; however, the City would need to coordinate the delivery schedule. Safety and Code Compliance. The applicable safety considerations and code requirements for 12.5% strength liquid hypochlorite are as follows: O Sodium hypochlorite solution is considered a hazardous material per the 2006 IFC for the following reasons: Health Hazard — Corrosive. It should be noted that while some material data safety sheets list sodium hypochlorite solution as an oxidizer, neither the 2006 IFC nor the National Fire Protection Agency define sodium hypochlorite solution as an oxidizer. The IFC stipulates Maximum Allowable Quantities (MAQs) for storage and open system use that, if exceeded, trigger an H-3 occupancy rating as defined in the IBC. Assuming the 2006 IFC hazardous material designation is based solely on Health Hazard — Corrosive, the controlling MAQ for sodium hypochlorite solution is 500 gallons. However, if the storage area has automatic sprinklers, the MAQ is increased to 1,000 gallons. O An H-3 occupancy rating would require the following for the storage and use areas: o Spill control and secondary containment. o Liquid -tight surfacing in the containment area. o Automatic sprinkler system designed to no less than Hazard Group 2 requirements. o Mechanical exhaust ventilation system with standby power. o Temperature control. o Emergency alarm, both local and possibly call -out. o One -hour fire -resistance rating for walls/barriers. o Hazardous Materials Management Plan. o Additional measures may be required by the Fire Marshall. O Sodium hypochlorite solution is not listed as a hazardous material under either OSHA regulated Title 29 CFR, 1910.119 — process safety management of highly hazardous chemicals; or EPA regulated Title 40 CFR, 68 — chemical accident prevention provisions. O Regarding operator safety, when working with or near concentrated liquid hypochlorite or "breaking" any pipe connection that is subject to hypochlorite exposure, operators should wear personal protective equipment including safety goggles and chemical -resistant gloves. An emergency shower and eyewash station should be provided. Well SA Chlorine Evaluation 2 City of Renton Project Number 51403 Operations & Maintenance Requirements. The routine O&M activities associated with commercial liquid hypochlorite storage and feed include: O Recharging the supply of hypochlorite, i.e., attending to deliveries of new solution. O Chlorination process monitoring and physical inspections. O Preparation of records and reports. O Periodic calibration and maintenance of the chemical metering pumps. O Periodic cleaning of the tanks and injection assemblies. O General housekeeping and preventative maintenance for chlorine system components. Based on similar projects, the labor estimates associated with these tasks are as follows: O 5.0 hours per week during peak use for operations (13 weeks/year) O 2.0 hours per week during off-peak use for operations (39 weeks/year) O 0.6 hours per week (five-year average) for routine maintenance Over the course of an average year, this chlorine method will require about 165 hours of routine O&M labor effort, or about 0.08 full-time equivalents (FTE). It should be noted that this estimate only applies to O&M labor for the chlorine system -related components. Other Considerations. Commercial liquid hypochlorite is prone to strength decay over time. As a result, it is common to limit onsite storage capacity to no more than a two- to three-week supply (i.e., 14 to 21 days). During periods of infrequent well operation, a reduced supply quantity and onsite storage capacity is desirable to minimize strength decay. 2.2 On -Site Hypochlorite Generation Process Description. In this process, an electrical current is applied to brine solution in electrolytic cells to produce a low -strength solution (0.8% by weight) of liquid sodium hypochlorite. The brine solution is prepared from coarse sodium chloride salt dissolved in water. Salt must be delivered to the site on a regular basis and loaded into a brine saturator tank as needed. For small applications such as this, the generation system is typically supplied as a pre-engineered package system which typically includes: a water softener, brine saturator tank, brine transfer pump, electrolytic reactor cell, power rectifier, hypochlorite solution tanks with venting system, chemical metering pumps, and associated controls and piping. The process uses about three pounds of salt and 2.5 kWh of energy per pound of C12 generated. Safety and Code Compliance. The applicable safety considerations and code requirements for 0.8% strength sodium hypochlorite generated on -site are as follows: O Although sodium hypochlorite solution is listed as a hazardous material under the 2006 IFC (Chapter 27), it is not clear if the Health Hazard — Corrosive designation would apply to such a low -strength solution. This issue and the associated occupancy requirements would need to be resolved with the Fire Marshall. O For this stage of planning, it is assumed that H-3 occupancy requirements would not apply; however, the secondary containment measures would be applied to preclude spills/release to the environment. Well SA Chlorine Evaluation 3 City of Renton Project Number 51403 O Additional measures may be required by the Fire Marshall, including a Hazardous Materials Management Plan. O Regarding operator safety, when working with or near liquid hypochlorite or "breaking" any pipe connection that is subject to hypochlorite exposure, operators should wear personal protective equipment including safety goggles and chemical -resistant gloves. An emergency shower and eyewash station should be provided. In general though, the exposure risks for 0.8% hypochlorite solution are significantly less than those for a 12.5% hypochlorite solution. Operations & Maintenance Requirements. The routine O&M activities associated with on -site generation, storage, and feed of 0.8% hypochlorite solution include: O Recharging the supply of brine, i.e., deliveries and handling of salt and loading salt into the brine saturator (i.e., opening and dumping bags). O Periodic calibration, maintenance, and eventual replacement of metering pumps, transfer pumps, and blowers. O Periodic cleaning of the tanks, injection assemblies, and electrolyzers. O Replacement of electrodes approximately once every five to seven years. O Monitoring and recording of chlorine use and chlorine concentrations. O General housekeeping and preventative maintenance for chlorine system components Based on similar projects and estimates from the equipment supplier, the labor estimates associated with these tasks are as follows: O 6 hours per week during peak use for operations (13 weeks/year) O 2 hours per week during off-peak use for operations (39 weeks/year) O 1 hours per week (five-year average) for routine maintenance Over the course of an average year, this chlorine method will require about 167 hours of routine O&M labor effort, or about 0.08 full-time equivalents (FTE). It should be noted that this estimate only applies to O&M labor for the chlorine system -related components. Other Considerations. Because of its low -strength, 0.8% hypochlorite solution is quite stable and can be stored for long periods of time. Also, since the system is used to produce hypochlorite "on - demand", it could be shut down as needed to preclude the storage of hypochlorite and the need for extensive equipment O&M during extended periods of well downtime. 3.0 Preliminary Design Criteria Preliminary design criteria for the chlorination systems have been developed in order to support the evaluation. These criteria have been developed for the purpose of a planning -level comparison and should not be considered the firm design criteria for the new facility. Firm design criteria will be established as part of the treatment system basis of design technical memorandum. 3.1 Well Production Well 5A Chlorine Evaluation 4 City of Renton Project Number 51403 The current nominal capacity of Well 5A is 1,500 gallons per minute (gpm), based on the approved instantaneous withdrawal water right (Certificate Record No. 8, Page 3591-A: 1,300 gpm, and Certificate Record No. 12, Page 5834-A, 200 gpm). As Well 5A is one of several sources of supply available to the City, it is anticipated that the new Well 5A treatment facility will be operated primarily during the summer to meet peak demands. The following preliminary assumptions have been made regarding well operation and production: O Continuous operation (100%) during the three peak months of July through September (e.g., 13 weeks per year). This translates into 2.2 million gallons per day (mgd) of production, neglecting plant process water losses and downtime for backwashing. O Intermittent operation (10%) during the nine off-peak months of October through June (e.g., 39 weeks per year). This translates into an average day off-peak production of 0.22 mgd, neglecting plant process water losses and downtime for backwashing. Therefore, on an annual basis, Well 5A would be operated about 33% of the time. This translates into an annual average day supply of 0.70 mgd and an annual supply of 786 acre-feet/year (afy), which is well below the approved annual withdrawal water right of 2,320 afy (Certificate Record No. 8, Page 3591-A: 2,000 afy and Certificate Record No. 12, Page 5834-A, 320 afy). 3.2 Chlorine Feed The chlorine system will be designed to allow the City to reliably achieve a free chlorine residual of 1.0 mg/L as C12, or any desired setpoint between 0.3 and 1.5 mg/L as C12, in the finished water prior to distribution. The applied chlorine dose must be adequate to satisfy the chlorine demand due to naturally -occurring iron, manganese, sulfide, and ammonia. As documented in the Well 5A Water Treatment Improvements Draft Pilot Test Report (HDR, July 2006), the average chlorine demand of the Well 5A raw water is 2.4 mg/L as C12; however, the demand may fluctuate from 1.8 to 3.2 mg/L as C12 due to variability in raw water quality, primarily the ammonia concentration. Therefore, in order to reliably achieve a finished water free chlorine residual of 1.0 mg/L as C12, the feed system should allow for dosages between 2.8 and 4.2 mg/L as C12. The average expected dose requirement is 3.4 mg/L as C12. Table 1 provides a summary of the chlorine dose and instantaneous feed rate requirements. The feed rate requirements were based on the Well 5A maximum production rate of 1,500 gpm and are expressed as pounds per day of chlorine (lb/day of C12), gallons per day of commercial 12.5% hypochlorite solution (assuming 1.25 lb/gal of Cl2), and gallons per day of on -site generated 0.8% hypochlorite solution (assuming 0.067 lb/gal of C12). The actual daily consumption (in gallons of solution per day) would depend on the fraction of time the well is operated on a given day. Table 1.

Maximum 4.2 76 60 f 1,134 For 12.5% hypochlorite, the metering pumps should be sized to deliver about 1.5 to 2.5 gallons per hour (gph), and potentially more if flexibility to provide a finished water free chlorine residual of 1.5 mg/L as C12 is desired. For 0.8% hypochlorite, the metering pumps should be sized to deliver about 30 to 50 gallons per hour, and potentially more if flexibility to provide a finished water free chlorine residual of 1.5 mg/L as C12 is desired. Regarding the feed systems, for the purpose of cost estimation, it was assumed that two identical chemical metering pumps would be provided. Only one pump would be on-line at any given time, with the other pump maintained as a backup. Re -chlorination metering pumps will also be provided to boost free chlorine residual, if necessary, following the extended contact period. It was assumed that these pumps would be sized to provide a nominal chlorine dose of 0.5 mg/L as C12. For 12.5% hypochlorite, the metering pumps should be sized to deliver about 0.3 gallons per hour. For 0.8% hypochlorite, the metering pumps should be sized to deliver about 5.6 gallons per hour. As before, it was assumed that two identical chemical metering pumps would be provided. Only one pump would be on-line at any given time, with the other pump maintained as a backup. The chemical metering pumps would be housed in the new treatment facility along with additional system components, including the piping manifold, calibration cylinder, and valving for isolation, backpressure, and pressure/air-relief. The on -site generation process requires salt at a rate of about three pounds per pound of chlorine produced. At a peak month chlorine production rate of 61 lb/day as C12, the salt consumption rate would be about 185 pounds per day or 1,300 pounds per week. This would require use of about 26 salt bags (at 50 pounds each) per week. It may also be possible to use supersacks, which typically contain about 1,500 pounds of salt. 3.3 Storage Capacity 3.3.1 Commercial Liquid Hypochlorite For 12.5% hypochlorite solution, it is common to limit the onsite storage capacity to no more than a two- or three-week supply in order to preclude strength decay. For this evaluation, it has been assumed that adequate storage would be provided for a 15-day supply under the peak month conditions (assuming average dose conditions), which would require about 740 gallons of solution. Owing to this relatively low storage volume, it may be more economical to use three 250- to 300- gallon totes as opposed to bulk delivery from a tanker truck. This is due to the fact that the costs for a tanker truck delivery are based on freight of a full truck, but since only a small fraction of the truck capacity would be supplied (i.e., 740 of about 4,000 gallons), the unit cost of hypochlorite (i.e., in dollars per gallon of solution) would be extremely high. Regardless of the approach used, the storage containers would be located within a secondary containment area sized to hold the contents of the largest container plus fire sprinkler flow. During periods of infrequent well use, the solution storage time will inevitably be higher, which could pose problems with regard to strength decay and/or off -gassing. During this period, it may be desirable to supply only one 300-gallon tote. Well SA Chlorine Evaluation 6 City of Renton Project Number 51403 3.3.2 On -Site Hypochlorite Generation For 0.8% hypochlorite solution, the storage requirements are reduced since the system would be designed to generate hypochlorite at the maximum anticipated instantaneous chlorine use rate. For this evaluation, it has been assumed that adequate storage would be provided for a three-day supply under peak operating conditions (assuming average chlorine dose conditions), which would require about 2,800 gallons. For redundancy, it was assumed that two 1,400-gallon dedicated tanks would be provided. These tanks would be located within a secondary containment area sized to hold the contents of a single tank. The on -site generation process also requires periodic salt delivery and unloading into a brine tank. During the peak well operation period, it is estimated that the process will require about 185 lb/day of salt. Over the course of a week, this will require about 1,300 pounds of salt, which is about 26 bags at 50-1b each. Because the cost of delivered salt is primarily attributed to transportation costs (i.e., cost per delivery as opposed to cost per amount of salt), it is desirable to reduce the frequency of delivery by storing more salt onsite. Therefore, it was assumed that adequate storage capacity and space would be provided for a one -month supply under the peak operating period. This translates into about 100 bags at 50-1b each. The 50-lb salt bags are typically supplied with 48 per pallet; therefore, a two -pallet supply would be required about once per month during peak well operation. Alternatively, the City could have four 1,500-1b supersacks delivered to the site. It was assumed that the brine saturator salt capacity would be adequate for about one -week of operation during peak well use, plus some additional capacity to provide a minimum salt level. Therefore, about once per week, plant operators would need to replenish the saturator with about 26 bags (50-lb each) or one supersack (1,500-lb each). For the supersack option, special equipment such as a hoist may be required to move the supersack from the storage area above the brine tank for salt unloading. 4.0 Cost Estimation Preliminary capital and O&M cost estimates have been developed for the two chlorination methods. It should be noted that the estimates presented in this section are only intended to address the specific elements of the chlorine -related components. They are provided for comparative purposes only and therefore should be considered incremental to the costs for other facility construction requirements, such as civil/site work and structural, including building space. Finally, the cost estimates do not include design, legal, administration, permitting, contractor overhead and profit, or construction -related services. 4.1 Construction Costs Construction -related capital cost estimates were developed using bid results from similar projects and vendor -supplied budgetary proposals. The cost estimates have been updated to January 2007 using the Engineering News Record construction cost index. Labor costs for equipment installation were assumed to be 10% of the equipment cost (EQ). Allowances for mechanical, electrical, and instrumentation & control (I&C) have also been included. An estimating contingency of 30% has been applied to the sub -total reflect the fact that these are conceptual -level estimates. Well 5A Chlorine Evaluation 7 City of Renton Project Number 51403 While project permitting costs have not been addressed in the estimates, an incremental permitting and code -related cost of $10,000 was assumed for the commercial hypochlorite method. For the on -site hypochlorite generation system, a budgetary estimate was obtained for the Wallace & Tiernan OSECR B-Series, assuming a 90 lb/day of C12 production capacity (note: the OSECR B- series production capacities are discretized; furthermore, a capacity above the expected maximum day production is desirable to permit some equipment downtime during a portion of the maximum day). For either method, a concrete or asphalt -paved access area would be needed to allow a commercial vendor to unload the consumables. Since this cost is common to both alternatives, it has not been included in the estimates. Note that the delivery trucks are typically equipped with a lift gate and electronic pallet jack or forklift; therefore, a City -owned forklift would not be required. However, if the City elected to use salt supersacks, a hoist or other equipment may be required to move the supersacks for loading into the brine saturator. Table 2 provides a summary of the comparative construction -related capital cost breakdown for the two chlorination methods. The on -site generation method has a substantially higher construction cost due to the more extensive equipment requirements. Table 2.

It was assumed that well production would not increase significantly over the planning horizon. O The unit cost of commercial 12.5% hypochlorite solution delivered to the site in increments of three 300-gallon totes is estimated at $2.00/gallon (Univar, 2007). Well 5A Chlorine Evaluation 8 City of Renton Project Number 51403 O The unit cost of coarse salt delivered in increments of two pallets at 48 bags (at 50-lb each) per pallet is estimated at $0.15/lb (Univar, 2007). O Regarding energy costs (for on -site hypochlorite generation), a unit cost of $0.06 per kWh was assumed. The energy costs associated with chemical metering and ancillary energy use for both systems were neglected as they are assumed to be about equal and relatively small. O Regarding labor costs, an annual unit cost of $60,000 per FTE was assumed. The routine O&M labor hours for each method were previously documented in Section 2. O An annual maintenance allowance of 1.5% was applied to the equipment (EQ) sub -total from Table 2. Table 3 provides a summary of the comparative annual O&M costs for the two chlorination methods. The on -site generation method has a lower estimated annual O&M cost, due primarily to the low cost of energy and salt relative to delivered commercial hypochlorite. Table 3.

The life -cycle cost estimates were developed based on a 20-year time horizon and a 6% discount rate (consisting of 9% interest rate with 3% annual inflation). The results, which are summarized in Table 4, indicate that the commercial hypochlorite method has a significantly lower life -cycle cost. A brief sensitivity analysis was performed using a discount rate as low as 3%. In this case, the commercial hypochlorite option was still about $150,000 less than the on -site generation process on a life -cycle basis. Table 4.

A discussion of each method as it relates to these criteria is provided below. 5.1 Life -Cycle Costs A comparison of 20-year life -cycle costs was previously provided in Table 4. The commercial hypochlorite method is expected to have substantially lower costs on both a capital and net present worth basis. 5.2 Space Requirements Commercial Hypochlorite: Hypochlorite storage space was based on the supply of three 300-gallon totes. Assuming each tote is about 4-ft by 4-ft in size, and assuming 2-ft of clearance around each tote, the secondary containment area would be about 160 square feet (sft). An additional area of about 20 sft would be required for the metering pumps and feed system components. Therefore, the total floor space for the commercial hypochlorite system is about 180 sft. On -Site Generation: Salt storage space was based on the supply of two pallets, each carrying about 48 bags (at 50-lb each). Assuming each pallet is about 4-ft by 4-ft in size, and assuming 2-ft of clearance around each pallet, the salt bag storage area would be about 110 sft. Depending on how the salt bags were to be loaded into the brine tank, additional access space for use of a forklift may be needed. Hypochlorite storage space was based on the use of two 1,400-gallon tanks. Assuming each tank has a diameter of 5.5-ft, and assuming 3-ft of clearance around each tank, the secondary containment area would be about 160 sft. An additional area of about 150 sft would be required for the on -site generation equipment, controls, brine saturator tank, metering pumps, and feed system components. Therefore, the total estimated footprint for this system is about 420 sft. As noted earlier, the cost estimates do not include building footprint for the chemical storage and feed systems. However, the on -site generation system will require substantial additional footprint relative to the commercial hypochlorite method. This will increase the capital costs of the building. 5.3 Operational Considerations Commercial Hypochlorite: This method is the most simple to operate and maintain. It is similar to the hypochlorite feed system used at the Maplewood Water Treatment Facility, so City staff would already be familiar with the O&M requirements. With concentrated hypochlorite solution, there is the potential for off -gassing and vapor -lock issues, though these can generally be avoided with proper design and operation. Another potential concern with this method involves its use in an intermittent -type operation, such as near -continuous use during periods of high demand and little - Well 5A Chlorine Evaluation 10 City of Renton Project Number 51403 to -no use during other periods. With extended storage and/or system downtime, commercial hypochlorite solution may experience significant strength decay and there is a greater likelihood of off -gassing and vapor -lock upon start-up. One possible approach to address this is to supply fewer totes during periods of infrequent well use. On -Site Generation: This method is expected to be more complicated to operate and maintain as it relies on successful operation of several unit processes and pieces of equipment in order to produce hypochlorite solution, i.e., there are more points of failure. The City does not currently have any other on -site generation systems; therefore, City staff would require training to develop familiarity with this technology. However, it should be noted that with proper preventative maintenance, these systems have proven to be reliable at other installations. This method offers greater operational flexibility for an intermittent -type operation because the generation system can be started quickly (assuming enough salt is on -hand), hypochlorite can be produced in an "on -demand" mode, and the 0.8% hypochlorite solution is relatively stable. 5.4 Safety Considerations Commercial Hypochlorite: Per 2006 IFC, hypochlorite solution is not considered a toxic material. However, skin exposure to commercial hypochlorite can result in severe swelling and burning within a short period of time. Extended exposure can cause blistering and permanent skin damage. Also, commercial hypochlorite solution poses a greater risk of chlorine off -gassing and inhalation hazard in the event that the solution pH is reduced. It is imperative that operators wear personal protective equipment when working with or near liquid hypochlorite or "breaking" any pipe connection that is subject to hypochlorite exposure. An emergency shower and eyewash station will be provided. On -Site Generation: Low -strength hypochlorite generated on -site can produce similar effects as the commercial hypochlorite; however, it would require longer exposure duration to do so. This would allow operators to use an emergency safety shower and/or eyewash to reduce the degree of health impacts following exposure. It is still advised for operators to wear personal protective equipment when working with or near liquid hypochlorite or "breaking" any pipe connection that is subject to hypochlorite exposure. An emergency shower and eyewash station may be required. There are no chemical safety concerns for salt handling. The electrolyzers will require periodic cleaning with an acid -solution, which also would involve operator training and use of personal protective equipment. 5.5 Summary Table 5 provides a qualitative summary and comparison of the two chlorination methods.

DRAFT — Well 5A Chlorine Evaluation 12 City of Renton (Project Number 51403) 6.0 Recommendation Based on the evaluation and comparison of liquid chlorination alternatives, the use of commercial 12.5% hypochlorite solution appears to be the preferred method for chlorine feed at the Well 5A facility. It would be possible to use either dedicated storage tanks or small exchangeable totes, depending on the operational needs and preferences of the City: ) The following highlights summarize the basis for these conclusions.

The purpose of this memorandum is to provide an overview and comparative evaluation for placement of the IGAC contactors and greensand filter pressure vessels that will be incorporated within the design of the new treatment facility for Well 5A. The two general alternatives discussed involve the advantages/disadvantages associated with either interior or exterior placement of the vessels. The following assumptions are made as part of this memorandum: The materials of construction for the pressure vessels, piping, and appurtenances would remain the same, regardless of interior or exterior placement, and differences in cost for the specified paint coating systems of each are inconsequential. Grated platforms, to provide operators access to the access hatches, piping, and equipment located on the upper portions of the vessels, are assumed to be desirable and equivalent with both alternatives. Operation and maintenance (O&M) costs are considered to be equivalent between the two options, even though some subtle differences exist. Among these differences are exterior vessels might require slightly more frequent painting and maintenance due to exposure to weather, whereas interior vessels would necessitate more energy cost associated with HVAC (including increased dehumidifying for condensation control) and could also require additional capital cost for a larger sprinkler system that would be required under a building "H" occupancy rating. Though the O&M would likely be slightly higher for interior placement, estimating costs associated with these potential differences are felt to be unnecessary in making an overall decision on which way the City of Renton (City) proceeds. Therefore, a life cycle cost analysis is not considered, and cost comparisons will be based solely on conceptual level opinions of probable construction costs. The filter face piping and electric motor actuated valves would be located inside the building for both options.

City of Renton Water Utility 27 February 2007 Page 2 Pressure Vessel Sizing The Well 5A Pilot Test Report by HDR evaluated different hydraulic loading rates across the granular activated carbon media in the contactors and the greensand/anthracite cap media within the pressure filters. The loading rates were varied from 5 to 12 gallons per minute (gpm) per square foot (ft2) for each of the two treatment processes, which were typically connected in series under varying chemical treatment techniques and in the presence of different varieties of greensand media (GS and GS+). The results of testing indicated that effective removal of manganese, the most difficult constituent to remove, was obtained at maximum loading rates of 12 gpm/ft2, though the efficacy and reliability were better at a rate of 10 gpm/ft2. For this reason, a design criteria target loading rate for filtration of 10 gpm/ft2 is recommended. Given the City's desire to attempt to fully utilize their maximum instantaneous water right (Q) of 1500 gpm, a surface area of 150 ft2 is needed for both the GAC and greensand media beds. In order to furnish some level of production redundancy, but at the same time limit the number of vessels, two GAC contactors and two greensand pressure vessels are recommended. Each of the four vessels has an approximate square footage of 78.5 ft2. These sizes were endorsed by three locally represented pressure vessel/greensand filter suppliers. Note with the flow split between two vessels in a unit process, it will be necessary to shut down the well while the backwash sequence as it is not desirable to double the flow rate through one vessel to approximately 20 gpm/ft2 while the other is being backwashed. The vessel heights are determined through manufacturer recommended media depths necessary to achieve adequate empty bed contact times (EBCT) that will adequately reduce hydrogen sulfide levels through the GAC contactors and iron and manganese in the greensand filters. Additional depth is required for upper and lower distribution systems, and adequate freeboard to achieve desired media expansion during backwashing. It is anticipated that these design parameters will be similar to the Maplewood facility. Conceptual Level Construction Cost Comparison Based on allowing adequate spacing between filters for maintenance access and piping connections, a general footprint necessary to accommodate the filters is recommended to be a rectangular area of 65 feet long by 18 feet wide, or approximately 1,170 ft2. This area is also illustrated in the preliminary building layout, included with this memo as Attachment A. If the vessels were placed within the treatment facility building, they would then logically add 1,170 ft2 of additional square footage to the building size, with associated additional material costs. If the vessels were placed outside, the building could not only be reduced in footprint, but also in height, as the vessels would likely govern the necessary eave height. For aesthetic reasons, a perimeter curtain wall, assumed to be of CMU construction, could be provided on two sides of the slab that supports the vessels. A security fence could be installed across the backside if desired. W:\2006\0697005.01_HDR Renton Well\06-Corrspnd\6.03-Other\2007\02cwk 1 tm.

The proposal will be routed to other City departments and other jurisdictions or agencies who may have an interest in the application. The reviewers have two weeks to return their comments to the Development Services Division. Within approximately two weeks, the Development Services Division will prepare a report regarding the proposal's compliance with applicable codes and the City's review criteria. All applications requiring environmental review will be presented to the City's Environmental Review Committee. The Environmental Review Committee is comprised of the Administrator of the Planning/Building/Public Works Department, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and will then issue its decision (Environmental Threshold Determination). The Environmental Review Committee will either issue .a: Determination of Non -Significance (DNS) -Make a determination the proposal will have no significant negative environmental impacts, or Mitigated Determination of Non -Significance (DNS-M)-Make a determination the proposal, if modified, would have no significant negative environmental impacts, or PW/DevServ/Forms/Planning/siteplan1 8 04/06 Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified consultant. Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is not required), a public notice of the Determination is printed in the South County Journal and three notices are posted at or near the site. A 14-day appeal period commences following the publication date. At the discretion of the City, a separate and additional 15-day comment period may be added prior to the 14-day appeal period. In addition to issuing the Environmental Determination, the Environmental Review Committee is also charged with determining whether a public hearing should be required for those Site Plan proposals not automatically triggering a public hearing. The Environmental Review Committee will consider the departmental and public comments in determining whether or not a hearing should be required. This determination may be appealed within 14 days to the Hearing Examiner pursuant to Renton Municipal Code, Section 4-8-110. Projects exceeding the size limits listed in the Renton Municipal Code, Section 4-9-200D3 and projects abutting or across the street from residential zones MUST have a public hearing. No variance from this requirement is possible. The remainder of the review process differs depending on whether a public hearing is required. Administrative Site Plan Review: A public hearing is not required. The Development -- "' -Services Division reviews the proposal for compliance with the requirements of RMC 4- 9-200E, F in conjunction with the Environmental Review Committee decision and any staff or public comments prior to making a decision. The decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master Application and all parties of record. Hearing Examiner Site Plan Review and Review of Environmental Determination Appeals: A public hearing is required. After review of the proposal and any staff or public comments, the Development Services Division staff will forward a report and recommendation and the Environmental Review Committee decision to the Hearing Examiner prior to the hearing. This report will be mailed to all persons listed on the Master Application and all parties of record. Notice of the public hearing will be published in the South County Journal at least 10 days prior to the hearing, the site will be posted again, and parties of record will receive notices of the hearing via mail. Applicants are strongly encouraged to attend the public hearing for their proposal. City staff will first make a presentation to the Hearing Examiner about the proposal. Either the applicant or citizens in support of the proposal will then give testimony. When giving testimony, names and addresses must be stated for the record. Following this, individuals with neutral or opposing comments will give their testimony to the Hearing Examiner. City staff or the applicant will address additional questions raised throughout the hearing. The Hearing Examiner will review the proposed application for compliance with the requirements of RMC 4-9-200E and F concurrently with any environmental appeals and issue a final decision(s) within 14 days of the hearing unless, at the time of the public hearing, the Hearing Examiner indicates additional time will be required for issuance of the decision. The decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master Application and all parties of record. The Examiner's decisiqn on any environmental appeals will also be mailed. PW/DevServ/Forms/Planning/siteplan1 9 04/06 APPEAL AND RECONSIDERATION PROCESS FOR DECISIONS: Any person, including the applicant, aggrieved by the granting or denial of an application, may make a written application for reconsideration to the Reviewing Official within 14 calendar days of the date of the decision. After review of the request, the Reviewing Official may take whatever action is deemed proper.

BUILDING AND CONSTRUCTION PERMIT ISSUANCE AND INSTALLATION OF IMPROVEMENTS: In the City of Renton, a Building Permit must be obtained to build buildings and structures. A Construction Permit must be obtained to install utility lines, transportation improvements and undertake work in City right-of-ways. Building and Construction Permits are separate permits. Applicants may apply for building and construction permits concurrently with- their request for a land use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. DEFERRAL OF IMPROVEMENTS: If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings must be submitted to the Development Services Division. The application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an irrevocable letter of credit, set -aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements. EXPIRATION AND EXTENSIONS: Once an application has been approved, the applicant has two years to comply with all conditions of approval and to apply for any necessary permits before the approval becomes null and void. The approval body that approved the original application may grant a single two-year extension. The approval body may require a public hearing for such extension.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject, proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Provide City officials with information to evaluate, approve, condition or deny public or private development proposals with regard to critical area impacts; d. Protect the public life, health, safety, welfare, and property by minimizing and managing the adverse environmental im- pacts of development within and abutting critical areas; and e. Protect the public from: i. Preventable maintenance and re- placement of public facilities needed when critical area functioning is im- paired; ii. Unnecessary costs for public emergency rescue and relief opera- tions; and iii. Potential litigation on improper construction practices occurring in critical areas. 2. Aquifer Protection: The overall purpose of the aquifer protection regulations is to pro- tect aquifers used as potable water supply sources by the City from contamination by hazardous materials. Other specific purposes include: a. Protect the groundwater resources of the City; b. Provide a means of regulating spe- cific land uses within aquifer protection areas; c. Provide a means of establishing safe construction practices for projects built within an aquifer protection area; and d. Protect the City's drinking water sup- ply from impacts by facilities that store, handle, treat, use, or produce sub- stances that pose a hazard to groundwa- ter quality. 3. Flood Hazards: It is the purpose of the flood hazard regulations to: a. Minimize public and private losses due to flood conditions in specific areas; and b. Minimize expenditure of public money and costly flood control projects; and c. Minimize the need for rescue and re- lief efforts associated with flooding and generally undertaken at the expense of the general public; and d. Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in ar- eas of special flood hazard; and e. Help maintain a stable tax base by providing for the sound use and develop- ment of areas of special flood hazard so as to minimize future flood blight areas; and f. Ensure that those who occupy the ar- eas of special flood hazard assume re- sponsibility for their actions. 4. Geologic Hazards: The purposes of the geologic hazard regulations are to: a. Minimize damage due to landslide, subsidence or erosion through the con- trol of development; and b. Protect the public against avoidable losses due to maintenance and replace- ment of public facilities, property dam- 3 - 12.7 (Revised 3/06) 4-3-050B age, subsidy cost of public mitigation of avoidable impacts, and costs for public emergency rescue and relief operations; and c. Reduce the risks to the City and its citizens from development occurring on unstable slopes; and d. Control erosion and sediment run-off from development. 5.

Maintain and promote diversity of species and habitat within the City; and b. Coordinate habitat protection with the City's open space system, whenever possible, to maintain and provide habitat connections; and c. Help maintain air and water quality, and control erosion; and d. Serve as areas for recreation, educa- . tion, scientific study, and aesthetic appre- ciation. 6. Streams and Lakes: The purposes of the stream and lake regulations are to: a. Protect riparian habitat in order to provide for bank and channel stability, sustained water supply, flood storage, re- cruitment of woody debris, leaf litter, nu- trients, sediment and pollutant filtering, shade, shelter, and other functions that are important to both fish and wildlife; and b. Prevent the loss of riparian acreage and functions and strive for a net gain over present conditions through restora- tion where feasible; and c. Protect aquatic habitat for salmonid species. Other fish/aquatic species are addressed through Habitat Conservation regulations (see subsection A5 of this Section). 7. Wetlands: The purposes of the wetland regulations are to: a. Ensure that activities in or affecting wetlands do not threaten public safety, cause nuisances, or destroy or degrade natural wetland functions and values; and b. Preserve, protect and restore .wet- lands by regulating development within them and around them; and c. Protect the public from costs associ- ated with repair of downstream proper- ties resulting from erosion and flooding due to the loss of water storage capacity provided by wetlands; and d. Prevent the loss of wetland acreage and functions and strive for a net gain over present conditions. (Ord. 4851, 8-7-2000; Ord. 5137, 4-25-2005) B.

Plans and Studies Required: When an application is submitted for any building per- mit or land use review and/or to obtain ap- proval of a use, development or construction, the location of the critical areas and buffers on the site shall be indicated on the plans submitted based upon an inventory provided by a qualified specialist. 4. Submittal Requirements: See chapter 4-8 RMC. 5. Fees: See RMC 4-1-170. 6. Waiver of Submittal or Procedural Re- quirements: The Department Administrator may waive any of the requirements of this subsection if the size and complexity of the project does not warrant a step in the pro- ceeding and provided criteria to waive stud- ies are met in subsections H to M of this Section. 7. Independent Secondary Review: The City may require independent review of an applicant's report as follows: a. Aquifer Protection Areas, Flood Hazards, Habitat Conservation, Streams and Lakes, Wetlands: When appropriate due to the type of critical ar- eas, habitat, or species present, or project area conditions, the Reviewing Official may require the applicant to pre- 3 - 18.19 (Revised 6/05) 4-3-05OF are and/or fund analyses or activities, expense.

For on -site or off -site mitigation proposals, abutting or adjacent prop- erty owners shall be notified when wetland creation or restoration, stream relocation, critical area buffer increases, flood hazard mitigation, habitat conservation mitigation, or geologic hazard mitigation have the potential to considerably decrease the development potential of abutting or adjacent properties. For example, if a created wetland on a property would now result in a wetland buffer intruding onto a neighboring prop- erty, the neighboring property owner would be notified. Notification shall be given as follows: (a) For applications that are not subject to notices of application per chapter 4-8 RMC, notice of the mitigation proposal shall be given by posting the site and no- tifying abutting or adjacent prop- erty owners with the potential to be impacted. Written notification may be made prior to or at the time of the SEPA determination. (b) For applications that are subject to notices of application, the mitigation'proposal shall be identified in the notice of applica- tion and mailed to abutting or ad- jacent property owners with the potential to be impacted; if the determination of the mitigation requirements is not known at the time of the notice of application, written notice to abutting or adja; cent property owners shall be given instead at the time of the SEPA determination. b. Timing of Mitigation Plan — Final Submittal and Commencement: When a mitigation plan is required, the propo- nent shall submit a final mitigation plan for the approval of the Administrator prior to the issuance of building or construction permits for development. The proponent shall receive written approval of the miti- gation plan prior to commencement of any mitigation activity. (Ord. 5137, 4-25-2005) G. SURETY DEVICES: 1. Required for Mitigation Plans: For any mitigation plans required as a result of the ap- plication of these regulations, the Responsi- ble Official shall require a surety device to ensure performance consistent with RMC 4-1-230. 2. Time Period — Wetlands, Streams, and Lakes: For wetland and/or stream/lake miti- gation plans, the surety device shall be suffi- cient to guarantee that structures, improvements, and mitigation required by permit condition perform satisfactorily for a minimum of five (5) years after they have been completed. (Ord. 5137, 4-25-2005) H. AQUIFER PROTECTION: 1. Applicability: The aquifer protection regulations apply to uses, activities, and facil- ities located within an aquifer protection area (APA) as classified below. a. Aquifer Protection Area (APA): Aquifer protection areas are the portion of an aquifer within the zone of capture and recharge area for a well or well field owned or operated by the City, as de- picted in subsection Q1 of this Section, Maps. b. Aquifer Protection Zones: Zones of an APA are designated to provide graduated levels of aquifer protection. Zone boundaries are determined using best available science documented in the City of Renton Wellhead Protection Plan, an appendix of the City of Renton Water System Plan, as periodically updated. The following zones may be designated: i. Zone 1: The land area situated between a well or well field owned by the City and the three hundred sixty five (365) day groundwater travel time contour. ii. Zone 1 Modified: The same land area described for Zone 1 but for the purpose of protecting a high - priority well, wellfield, or spring with- drawing from an aquifer that is par- tially protected by overlying geologic strata. Uses, activities, and facilities 3 - 18.21 (Revised 6/05) 4-3-050L organization or land trust, or similarly pre- served through a permanent protective mechanism acceptable to the City. 5. Alterations Require Mitigation: If alter- ations to critical habitat/wildlife habitat or buff- ers are proposed, mitigation shall be required by the City. The applicant shall evaluate alter- native methods of developing the property using the following criteria in this order: a. Avoid any disturbances to the habitat. b. Minimize any impacts to the hab- itat. c. Compensate for any habitat im- pacts. 6. Mitigation Options: In addition to any performance standards or mitigation required by wetland regulations, additional mitigation may be determined by the Reviewing Official based upon the consultant report submitted by the applicant, and/or peer review of the ap- plicant's consultant report by a qualified pro- fessional selected by the City at the applicant's expense, and/or by information from State or Federal agencies. a. On -Site Mitigation: Mitigation shall be provided on -site, unless on -site miti- gation is not scientifically feasible due to physical features of the property. The burden of proof shall be on the applicant to demonstrate that mitigation cannot be provided on -site. b. Off -Site Mitigation: When mitiga- tion cannot be provided on -site, mitiga- tion shall be provided in the immediate vicinity of the permitted activity on prop- erty owned or controlled by the applicant, and identified as such through a recorded document such as an easement or cove- nant, provided such mitigation is benefi- cial to the habitat area and associated resources. c. In -Kind Mitigation: In -kind mitiga- tion shall be provided except when the applicant demonstrates and the City con- curs that greater functional and habitat value can be achieved through out -of - kind mitigation. 7. Mitigation Plan: Mitigation plans maybe required consistent with subsection F8 of this Section. (Ord. 5137, 4-25-2005) L. STREAMS AND LAKES: 1. Applicability/Lands to Which These Regulations Apply: These stream and lake regulations apply to sites containing all or portions of Class 2 to 4 streams or lakes and/ . or their buffers as described below. This sec- tion does not apply to Class 1 waters which are regulated by RMC 4-3-090, Shoreline Master Program Regulations, or to Class 5 waters which are exempt. All other critical area regulations, including, but not limited to, flood hazard regulations and wetland regula- tions, do apply to classified streams where applicable. a. Classification System: The follow- ing classification system is hereby adopted for the purposes of regulating streams and lakes in the City. Stream and lake buffer widths are based on the fol- lowing rating system: i. Class 1: Class 1 waters are pe- rennial salmonid-bearing waters which are classified by the City and State as Shorelines of the State. ff. Class 2: Class 2 waters are pe- rennial or intermittent salmonid-bear- ing waters which meet one or more of the following criteria: (a) Mapped on Figure Q4, Renton Water Class Map, as Class 2; and/or (b) Historically and/or currently known to support salmonids, in- cluding resident trout, at any stage in the species lifecycle; and/or (c) Is a water body (e.g., pond, lake) between one half (0.5) acre and twenty (20) acres in size. iil.

If the water body is un- mapped according to the City of Renton's Water Class Map (refer to subsection Q of this Section), and: 3 - 20.13 (Revised 6/05) 4-3-050L (a) The width of the stream channel averages less than two feet (2') at the ordinary high wa- ter mark; or (b) The stream channel has an average gradient of greater than twenty percent (20%); or (c) The channel or water body is upstream of an existing, en- during, and complete barrier to salmonid migration, as inter- preted in subsection L1 c(iv) of this Section, or as shown on the City of Renton's Salmonid Migra- tion Barrier Map, and the chan- nel or water body contains water only intermittently upstream of the barrier during years of nor- mal rainfall; or (d) The water body is isolated from any connected stream and/ or wetland; or (e) The water body is less than one-half (0.5) acre iri size and connected to a stream meeting the criteria noted in subsections L1c(iii)(a) through'(c) of this Sec- tion; Then the water body is consid- ered non-salmonid-bearing and water class would be assessed based upon the non-salmonid- bearing waters criteria in subsec- tions L1 a(iii) through (v) of this section. However, If none of the conditions above apply, then the water body is considered Salmo- nid-Bearing — Class 2. Classifi- cation of an unmapped stream or lake is effective upon expiration of the fourteen (14) day appeal period following the Administra- tor's determination, and the map in subsection Q of this Section shall be amended consistent with Administrator determina- tions at the next appropriate amendment cycle. iv. Salmonid Migration Barriers: For purposes of classifying or reclas- sifying water bodies, features deter- mined by the Administrator to be salmonid migration barriers per defi- nition in RMC 4-11-190 shall be mapped. The Administrator shall pre- pare and update the map as appro- priate and maintain a copy in the Planning/Building/Public Works Cus- tomer Service Area. v. Experts or State Agency May .Be Required or Consulted: The City may require an applicant to re- tain an expert or to consult the Wash- ington Department of Fish and Wildlife to assess salmonid-bearing status of the channel in question and prepare a report to the City detailing the facts and conclusion of their anal- ysis. vi. Criteria to Govern: The actual presence or absence of the stream and lake criteria listed in this subsec- tion L, as determined by qualified professionals, shall govern the treat- ment of an individual building site or parcel of land requiring compliance with these regulations. 2.

Ord. 4835, 3-27-2000) a. That the applicant suffers undue hardship and the variance is necessary because of special circumstances appli- cable to subject property, including size, shape, topography, location or surround- ings of the subject property, and the strict application of the Zoning Code is found to deprive subject property owner of rights and privileges enjoyed by other property owners in the vicinity and under identical zone classification; b. That the granting of the variance will not be materially detrimental to the public welfare or injurious to the property or im- provements in the vicinity and zone in which subject property is situated; c. That approval shall not constitute a grant of special privilege inconsistent with the limitation upon uses of other properties in the vicinity and zone in which the subject property is situated; d. That the approval as determined by the Reviewing Official is a minimum vari- ance that will accomplish the desired pur- pose. (Amd. Ord. 4835, 3-27-2000) 6. Special Review Criteria — Reasonable Use Variance — Critical Areas Regulations Only: For variance requests related to the critical areas regulations not subject to sub- sections B7 to 1311 of this Section, the Re- viewing Officia may grant a reasonable use variance if all of the following criteria are met: a. That the granting of the variance will not be materially detrimental to the public welfare or injurious to the property or im- provements in the vicinity and zone in which subject property is situated; b. There is no reasonable use of the property left if the requested variance is not granted; c. The variance granted is the minimum amount necessary to accommodate the proposal objectives; d. The need for the variance is not the result of actions of the applicant or prop- erty owner; and e. The proposed variance is based on consideration of the best available sci- ence as described in WAC 365-195-905; or where there is an absence of valid sci- entific information, the steps in RMC 4-9-25OF are followed. (Ord.. 4835, 3-27-2000; Amd. Ord. 4851, 8-21-2000) . 7. Special Review Criteria for Variances from the Aquifer Protection Regulations: Except for public or quasi -public utility or agency proposals which are subject to sub- section B10 of this Section, the Hearing Ex - (Revised 6/05) 9 - 74 4-9-250B aminer shall consider the following criteria, in addition to those criteria in subsections B5 and B6 of this Section, for variances from aquifer protection regulations: a. That the proposed activities will not cause significant degradation of ground- water or surface water quality; b. That the applicant has taken deliber- ate measures to minimize aquifer im- pacts, including but not limited to the following: i. Limiting the degree or magnitude of the hazardous material and activ- ity; and ii. Limiting the implementation of the hazardous material and activity; and iii. Using appropriate and best available technology; and iv. Taking affirmative steps to avoid or reduce impacts; and c.

(Ord. 4835, 3-27-2000; Amd. Ord. 4851, 8-21-2000) 8. Special Review Criteria for Variances from Flood Hazard Requirements in the Critical Areas Regulations: In lieu of the variance criteria of subsection B5 of this Sec- tion, the following directives and criteria shall be utilized by the Hearing Examiner in the re- view of variance applications related to the flood hazard requirements of the critical ar- eas regulations: a. Purpose and Intent: Variances, as interpreted in the national flood insurance program, are based on the general zon- ing law principle that they pertain to a physical piece of property; they are not personal in nature and do not pertain to the structure, its inhabitants, economic or financial circumstances. They primarily address small lots in densely populated residential neighborhoods. As such, vari- ances from the flood elevations should be quite rare. b. Review Criteria: In passing upon such an application for a variance, the Hearing Examiner shall consider the fol- lowing review criteria: i. Consider all technical evalua- tions, all relevant factors, standards specified in other sections of this sec- tion; and: (a) The danger that materials may be swept onto other lands to the injury of others; (b) The danger to life and prop- erty due to flooding or erosion damage; (c) The susceptibility of the pro- posed facility and its contents to flood damage and the effect of such damage on the individual owner; (d) The importance of the ser- vices provided by the proposed facility to the community; (e) The necessity to the facility of a waterfront location, where applicable; (f) The availability of alternative locations for the proposed use which are not subject to flooding or erosion damage; (g) The compatibility of the pro- posed use with existing and an- ticipated development; (h) The relationship of the pro- posed use to the comprehensive plan and flood plain manage- ment program for that area; 9 - 75 (Revised 6/05) 4-9-250B (i) The safety of access to the v.

Special Review Criteria — Single Fam- ily Residence on a Legal Lot with a Cate- gory 3 Wetland o Single Family esidence on a Legal Lot with a Class 2, 3 or 4 St ea ke n lieu of the criteria shown in subsections B5 and B6 of this Sec- tion, a variance may be granted from any wet- land or stream requirement in the critical areas regulations for a single family resi- dence to be located on an existing legal lot if all of the following criteria are met: a. The proposal is the minimum neces- sary to accommodate the building foot- print and access. In no case, however, shall the impervious surface exceed five thousand (5,000) square feet, including access. Otherwise the alteration shall be reviewed as a Hearing Examiner vari- ance and subject to the review criteria of subsection B6 of this Section; b. Access is located so as to have the least impact on the wetland and/or stream/lake and its buffer; c. The proposal preserves the functions and values of the wetlands and/or stream/lake/riparian habitat to the maxi- mum extent possible; d. The proposal includes on -site mitiga- tion to the maximum extent possible; e. The proposal first develops noncriti- cal area, then the critical area buffer, be- fore the critical area itself is developed; f. The proposed activities will not jeop- ardize the continued existence of endan= gered, threatened or sensitive species as listed by the Federal government or the State; g. The inability to derive reasonable economic use of the property is not the result of actions segregating or dividing the property and creating the undevelop- able condition after the effective date of this Section; and h. The proposed variance is based on consideration of the best available sci- ence as described in WAC 365-195-905; or where there is an absence of valid sci- entific information, the. steps in RMC 4-9-25OF are followed.

Public policies have been evaluated and it has been determined by the De- partment Administrator that the public's health, safety, and welfare is best served; b. Each facility must conform to the Comprehensive Land Use Plan and with any adopted public programs and poli- cies; c. Each facility must serve established, identified public needs; d. No practical alternative exists to meet the needs; e. The proposed action takes affirma- tive and appropriate measures to mini- mize and compensate for unavoidable impacts; f. The proposed activity results in no net loss of regulated wetland or stream/lake area, value, or function in the drainage basin where the wetland, stream or lake is located; g. The proposed activities will not jeop- ardize the continued existence of endan- gered, threatened or sensitive species as listed by the Federal government or the State; h. That the proposed activities will not cause significant degradation of ground- water or surface water quality; i. The approval as determined by the Hearing Examiner is a minimum variance that will accomplish the desired purpose; and 9 - 77 (Revised 6/05) 4-9-250B j. The proposed variance is based on consideration of the best available sci- ence as described in WAC 365-195-905; or where there is an absence of valid sci- entific information, the steps in RMC 4-9-25OF are followed.

Special Review Criteria — Construct- ing Structures over Piped Streams: or vanance requests involving the construction of structures over piped streams, the follow- ing criteria shall apply: a. The proposal is the minimum neces- sary to accommodate the structure; and b. There is no other reasonable alterna- tive to avoid building over a piped stream; and c. The existing pipe stream system that would have to be located under the struc- ture is replaced with new pipe material to ensure long-term life of the pipe and meets structural requirements; and d. The piped stream system is sized to convey the one hundred (100) year future land use condition runoff from the total upstream tributary area as determined from a hydrologic and hydraulic analysis performed in accordance with standards determined by the City and in accor- dance with other City's standards; and e. The piped stream that will be built over will need to be placed in a casing pipe sized to allow pipe skids and the po- tential need to increase the pipe size by a minimum of one pipe diameter. The cas- ing pipe shall be a minimum of three pipe diameters larger than the diameter of the pipe that conveys the stream; and f. To allow for maintenance, operation and replacement of the piped stream that has been built over, a flow bypass system shall be constructed and access man- holes or other structures of sufficient size as determined by the City shall be re- quired on both sides of the section of the piped stream that is built upon; and g. There will be no damage to nearby public or private property and no threat to the health or safety of people on or off the property. 12.

ABSENCE OF VALID SCIENTIFIC INFORMATION: Where there is an absence of valid scientific infor- mation or incomplete scientific information relat- ing to a critical area leading to uncertainty about the risk to critical area function of permitting an al- teration of or impact to the critical area, the Re- sponsible Official shall: 1. Take a "precautionary or a no -risk ap- proach" that appropriately limits development and land use activities until the uncertainty is sufficiently resolved, or determine that pro- tection can be ensured by using an approach different from that derived from the best avail- able science; provided, that the applicant demonstrates on the record how the alterna- r (Revised 6/05) 9 - 80 4-9-260 tive approach will protect the functions and values of the critical area; and 2. Require application of an effective adap- tive management program that relies on sci- entific methods to evaluate how well regulatory and nonregulatory actions protect the critical area. An adaptive management program is a formal and deliberate scientific approach to taking action and obtaining infor- mation in the face of uncertainty. An adaptive management program shall: a. Address funding for the research component of the adaptive management program; b. Change course based on the results and interpretation of new information that resolves uncertainties; and c. Commit to the appropriate timeframe and scale necessary to reliably evaluate regulatory and nonregulatory actions af- fecting protection of critical areas and anadromous fisheries.

Applicants may apply for building and.construction permits concurrently with their request for a land use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. DEFERRAL OF IMPROVEMENTS: If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings must be submitted to the Development Services Division. The application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an irrevocable letter of credit, set -aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts -,on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. t Governmental agencies use this checklist to determine whether the environmental impacts. of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonprojep proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Within each chapter there is a prescriptive and a component tradeoff approach that can be chosen for each trade. On the back of each trade checklist there is a flowchart to help you decide which approach can be used to show compliance. You still have the option of doing a Systems Analysis but those requirements will be found in the reference standard RS29 at the back of the code. THE FOLLOWING ITEMS ARE REQUIRED TO BE SHOWN ON THE PLANS: Envelope Requirements • Design criteria • Exterior envelope component materials • Wall, Floor and Ceiling U-factors or R-factors as appropriate to the compliance path • Glazing, U-factors and shading coefficients — added to the window schedule C. Slab insulation detail and R-factor •. Any pertinent special details that effect thermal efficiency Mechanical Requirements • Mechanical system (HVAC) schedule including size, efficiency rating and type of apparatus •. Economizer use and required controls • Fan system horsepower • 'Equipment and systems controls Electrical Requirements • Lighting and fixture schedule with model numbers, number of fixtures and wattage • Lighting controls narrative And any other pertinent data indicating compliance with the requirements of the code. The checklist must be completed so a comprehensive plan review can be conducted. The checklist will also be used by the Inspector to ensure compliance with the code. If you have questions on completing the checklist, contact Jan Conklin at (425) 430-72fi$ Q:web\pw\devserv\forms\building\WSECComm.doc Page 1 of 20 Rev 3/03 2004 Washinqton State Nonresidential Enerqv Code Compliance Form 2004 Washington State Nonresidential Energy Code Compliance Forms Revised May 2005 Project Info Project Address Date For Building Department Use Applicant Name: Applicant Address: Applicant Phone: Project Description ❑ New Building ❑ Addition ❑ Alteration ❑ Change of Use ❑ Prescriptive ❑ Component Performance El systems Analysis Compliance Option (See Decision Flowchart (over) for qualifications) Space Heat Type Q Electric resistance 0 All other (see over for definitions) Total Glazing Area Electronic version: these values are automatically taken from ENV-UA-1.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D).

Determination of nonsignificance (DNS): A DNS is issued by the SEPA lead agency after they have determined that a proposal is unlikely to have a significant adverse environmental impact or that all adverse impacts can be "mitigated" to a nonsignificant level. Determination of significance (DS): A DS is issued by the SEPA lead agency after they have determined that a proposal is likely to have one or more significant adverse environmental impacts that should be evaluated in an environmental impact statement (EIS). DNS: see "determination of nonsignificance" DS: see "determination of significance" EIS: see "environmental impact statement" Environmental checklist: A form that asks questions about various aspects of a proposal and that is evaluated by the SEPA "lead agency" to identify potential adverse environmental impacts. Environmental impact statement (EIS): An EIS is a document that includes analysis of probable significant adverse environmental impacts of a proposal, reasonable alternatives, and possible mitigation measures. Lead agency: The SEPA lead agency is responsible for completing the environmental review of a proposal and issuing the necessary SEPA documents, so that all permitting agencies can make informed decisions. Mitigation: Mitigation is avoiding, minimizing, rectifying (repairing), reducing, eliminating, compensating, or monitoring of environmental impacts. Scoping: Scoping is the initial step in the production of an EIS, where interested agencies, tribes, and the public have the opportunity to comment on issues to be focused on in the EIS. Scoping notice: see "determination of significance" and "scoping" SEPA Rules: Chapter 197-11 WAC, the rules adopted by the Department of Ecology to implement the Act. State Environmental Policy Act: Chapter 43.21 C RCW What is SEPA? The State Environmental Policy Act (SEPA) (chapter 43.21C RCW) was adopted in 1971 to ensure that environmental values were considered during decision -making by state and local agencies. The environmental review process in SEPA is designed to work with other regulations to provide a comprehensive review of a proposal. Most regulations focus on particular aspects of a proposal, while SEPA requires the identification and evaluation of probable impacts to all elements of the built and natural environment. Combining the review processes of SEPA and other laws reduces duplication and delay by combining study needs; combining comment periods and public notices; and allowing agencies, applicants, and the public to consider all aspects of a proposal at the same time. This guide will provide a general overview of the SEPA process for project applicants, including guidance in completing the environmental checklist. We understand that first experiences with unfamiliar processes are often frustrating. It is our hope to make the SEPA process as simple and understandable as possible for you. The SEPA process is used to identify and assess likely impacts to all elements of the built and the natural environment. As we discuss the SEPA process and your part in it, you 11 may find it helpful to look over and refer to the SEPA Review Process flow chart on the back of this document. You will also find a Glossary on page 2 to help you with unfamiliar terms. If after reading through the guide, you have any questions, Contact Numbers and Additional Resources are also listed on page 25, or you may contact the agency you are working with. Where do I begin? The SEPA process most often begins when you submit the first permit application for your proposal to a state or local agency. It may also be possible for you to have a pre - application meeting to discuss your project, permit requirements, and the SEPA process with the agency(ies) involved. Not all projects require SEPA (see "categorical exemptions" in the glossary for additional information); it is dependent on the size and character of what's proposed. The agency that will be making decisions on your project will tell you whether SEPA is required for your proposal. You, as the project applicant, will have responsibilities, such as filling out an environmental checklist, which asks questions about your proposal. Supplying accurate and complete information can save both time and money. Most steps in the SEPA process will be handled by the agencies that It is helpful to understand that will issue permits or other approvals for your project. One agency is SEPA is not a permit or identified as the SEPA "lead agency" and is responsible for approval; it is a process. completing the SEPA process. The determination of who is lead agency for your proposal is the responsibility of the agency who receives the first permit application. In most cases the lead agency will be the city or county will a permit to issue for your project. Lead agency responsibilities include: • Reviewing all environmental aspects of your proposal, including those under the jurisdiction of other agencies; • Identifying potential adverse environmental impacts; • Determining whether the environmental impacts of your proposal are likely to be significant after identified mitigation is applied; • Issuing the SEPA documents. (See SEPA Project Review, below.) SEPA Project Review The SEPA review process will begin for your proposal when you submit a completed environmental checklist. After initial review of the checklist, the lead agency must decide if they have enough information to identify the potential adverse environmental impacts of your proposal or whether additional information is required. Mitigation measures may be needed for adverse environmental impacts that are identified. Mitigation measures are changes or conditions added to your proposal that will avoid, minimize, or compensate for adverse impacts. • If your proposal is not likely to have a significant adverse environmental impact or mitigation has been identified to reduce the impacts sufficiently, a determination of nonsignificance (DNS) can be issued. The DNS may have a public and agency comment period. If mitigation cannot be easily identified to sufficiently reduce the likely significant adverse impacts of your proposal, an environmental impact statement (EIS) will be needed. The EIS is used to analyze your proposal, reasonable alternatives, and other methods that may be used to reduce or eliminate the adverse environmental impacts of your proposal. The lead agency begins by issuing a determination of significance (DS)/scoping notice for agencies and the public to review. "Scoping" is done to identify key issues related to your project that will be evaluated in the EIS. Agencies will use the information in the EIS or DNS when they make permit decisions. Permit conditions may be added to reduce the adverse impacts of your proposal. Under very rare circumstances, if an EIS shows there are likely adverse environmental impacts that cannot be reduced to an acceptable level, permits or other approvals for your proposal may be denied. It is also possible for permits to be denied under applicable permit regulations. Integrated Project Review If a city or county planning under the Growth Management Act (GMA) will be issuing a permit or other approval for your proposal, they must also follow the procedures of the Local Project Review Act (Chapter 36.7013 RCW). Although many aspects of the Local Project Review Act are similar or related to SEPA, they are separate laws. The purpose of the Local Project Review Act is to provide an opportunity for public and agency involvement early in the project review process and to fully integrate permit review with environmental review. When a GMA city or county receives your permit application and any additional information they determine necessary to begin their project review, they will issue a "determination of completeness." The determination of completeness is not a SEPA document, but is the first step in the integrated project review process. Soon after issuing the notice of completeness, the GMA city or county will issue a "notice of application." The notice of application is sent to interested agencies, and the public is given notice that they have 14 to 30 days to review and comment on your proposal. This provides an opportunity for other agencies and the public to become involved early in the review process when it is easiest for any needed changes to be made. A determination of completeness does not guarantee that additional information and/or studies will not be needed later in the review process. If the GMA city or county is also the SEPA lead agency for your proposal, at the agency's option, the comment period for the notice of application may be used to solicit comments on the DS (issued together) or the DNS (which is issued after the comment period ends). The integrated project review process ends with the GMA city or county issuing a notice of decision that states the decisions made on the project permit applications. How long will this take? SEPA review is intended to be integrated throughout an agency's permit review process, rather than a separate step. Most agencies make sincere efforts to process permit applications as efficiently as possible, while still addressing regulatory and environmental concerns. The time needed to review your proposal will depend on the permits needed, the complexity of the project, the amount of information already available, and the need to complete additional analysis or studies. In many cases, project review may be completed in two or three months. On the other hand, completing project review for some complex projects may take years. The SEPA lead agency can give you the best information on when their project review may be completed. You may also wish to discuss timing of permits and approvals with other agencies involved with your project. How much will this cost? Agencies are allowed to charge applicants for SEPA processing. These fees are not set by state law but by agency ordinances, and will vary greatly between one agency and another. If additional studies, such as a wetland delineation or traffic study, or an environmental impact statement are required, costs will be much greater. The best guidance is likely to be from the lead agency for your proposal. You may wish to talk this over with them before you get too far along in the process. Does every permit go through SEPA again? Usually, the lead agency completes the environmental review process for the entire proposal. All agencies that have permits to issue use the lead agency's environmental analysis and documentation in their decision -making. There are a few exceptions: NEPA is required by a federal agency. If you need a permit, approval, or funding from a federal agency, you may need to comply with the National Environmental Policy Act (NEPA). NEPA is very similar to SEPA, but it is a federal law and distinct from the state law. With good planning, the requirements of both NEPA and SEPA can be met at one time. It is also possible for NEPA documents to be adopted by state and local agencies to fulfill SEPA requirements (at the discretion of the SEPA lead agency). If you know that you will require federal permits for your project, it is a good idea to discuss the situation with the SEPA lead agency to see how NEPA and SEPA can best be completed. • Additional studies are needed by another agency. Other agencies that must issue a permit, approval, or funding for any portion of the proposal may need additional studies beyond those identified by the lead agency. These may be required under permit regulations, or through SEPA. How do I begin? Your first step in the SEPA process is filling out the environmental checklist. The purpose of the environmental checklist is to provide information to identify likely environmental impacts from proposals and to reduce or avoid these impacts, if possible. The agency will also use this information to decide whether the likely environmental impacts of the project need further study, have been adequately addressed by existing regulations, or can be mitigated. The checklist has questions about your project and both the built environment (land use, transportation, utilities and services, etc.) and the natural environment (water, air, plants, animals, etc.). As you complete the checklist, you should think of ways to reduce the impacts of your project. Modifications made by you or the permitting agencies are most easily integrated early in the development of your proposal. In most cases, you should be able to adequately answer most, if not all, of the questions yourself based on a familiarity with the project and the site. To help you with this, guidance is included, starting on page 8, on how to best answer the questions and where to get additional information for some questions. 6 A consultant may be needed if your proposal is complex or additional studies, such as a wetland report or transportation study, are requested by the lead agency. Some applicants prefer to hire a consultant to complete all of the necessary paperwork. Before you begin, scan through the checklist, so you are familiar with the range of questions. Often, one question will bring to mind information that will help you answer another more completely. Your complete and accurate answers on the checklist helps the agency determine what other agencies will have decisions related to your project, who will be lead agency, and how your proposal is likely to affect the environment. The checklist also provides information to other permitting agencies and those interested in your proposal. Complete each question to the best of your ability. An answer of "not applicable" should only be used after careful consideration of the question. Failing to provide adequate information is likely to delay the process. You are also encouraged to use any existing environmental analysis related to your proposal. Relevant studies may have been completed for local planning documents, such as a comprehensive plan or subarea plan, or for similar types of projects nearby. Giving information on past actions, related off site activities, and/or future expansions or activities planned in connection with your proposal allows the lead agency to decide what activities should be evaluated together. If enough information is available, the lead agency is able to complete the SEPA process for all related activities at one time. This can save both time and money by avoiding going through the SEPA process for each new addition or expansion, and speeding the permitting of later phases. The standard environmental checklist form can be found within the SEPA Rules at WAC 197-11-960. The SEPA Rules allow lead agencies to change Part A of the checklist to better suit their needs, so it is generally best for you to get a copy of the checklist directly from the lead agency. What is "mitigation"? During review of your proposal, the lead agency may identify possible adverse environmental impacts. If so, you and the agency can work together to identify ways to reduce the impacts, either through changes to the proposal or identification of mitigation measures. Mitigation measures are usually conditions placed on the permit or approval. Mitigation is defined as: Avoiding, Minimizing, Repairing or restoring, Reducing or eliminating over time, .• Replacing, enhancing, or providing substitute resources; and/or .• Monitoring the impact and taking appropriate corrective measures. For the purpose of the checklist it would be appropriate to generally describe what the corrective measures might be. Mitigation may involve almost anything, such as paying impact fees to local school districts, or changing the design of the project to avoid impacts to wetlands or other sensitive areas. Some mitigation may be required by city or county development regulations, or other local, state, or federal laws. Mitigation can also be based on information on adverse environmental impacts in the SEPA document. What if I need an EIS? When the lead agency reviews your proposal, they will attempt to identify mitigation for any adverse environmental impacts (see "What is Mitigation?" above). If the lead agency determines that your proposal, with the mitigation identified, is still likely to have a significant adverse impact to the environment, an environmental impact statement (EIS) is required. The EIS evaluates the adverse environmental impacts of various alternatives and explores possible mitigation to reduce the impacts. The lead agency determines how the EIS will be written, and they may ask or allow you to help in the preparation. The first step in the EIS process is called scoping. The public, interested tribes, and other agencies are asked to make comments suggesting areas of likely impact, potential mitigation, and possible alternatives to be examined in the EIS. After scoping, the lead agency must decide what will be covered in the EIS. They are not required to cover every alternative identified during scoping, but are likely to choose a number of alternatives that they feel cover the range of reasonable options. You, as the proponent, may be allowed some input in the shaping of the alternatives to be evaluated, but the decision lies with the lead agency. At a minimum, SEPA requires the evaluation of the proposal and a "no -action" alternative. The no -action alternative is usually defined by how things would be if there were no proposal. The lead agency will issue the draft EIS with a 30-day public comment period, with a possible 15-day extension. The lead agency will then prepare a final EIS that includes responses to comments received on the draft EIS. Agencies may make permitting decisions needed for your proposal seven days after the final EIS is issued. What if someone comments? One 'of the purposes of SEPA is to involve other agencies and the public in the review process. By allowing the public and agencies to comment on a SEPA document, concerns can be identified and evaluated before permits are issued. This can result in' better proposals and greater community acceptance of the final project. If comments are received on a: • DS/Scoping notice: the lead agency will consider the comments when they decide what will be assessed in the EIS. • Draft EIS: the lead agency must respond to all comments in the final EIS. This may involve changes to the alternatives and/or analysis, or may require new issues to be assessed. • DNS: the agency will evaluate the comments to decide how they should best be addressed and may require additional analysis. The DNS may be retained or modified, or it may be withdrawn and the impacts reconsidered. What if I change my mind? Changing your proposal after starting the review process can have a drastic effect on the ease or difficulty in completing the review process and receiving your permits. If adverse environmental impacts are avoided by the change, you are likely to ease the permitting process and may even avoid the need to do an environmental impact statement. On the other hand, if the review process is nearly or fully completed, significant changes may require portions of the process to be repeated. Incorporating environmental considerations with good planning is your best tool for a fast, efficient review process. If you choose, you may stop the review process at any time, simply by withdrawing your permit application. Filling out the Checklist The checklist asks you to describe the proposed project, the project site and surrounding area, and the likely changes to the environment that would result from the project. The information will be used by all agencies that have a permit or approval to issue for your proposal. The questions apply to all parts of your project, even if you plan to do them over a period of time or on different parcels of land. The following guidance is provided to assist you in completing the checklist. If an agency has revised Part A of the checklist, so that the numbers no longer coincide, the titles provided should assist you in locating the relevant material. You must answer each question accurately and carefully, to the best of your knowledge. Complete answers to the questions now may avoid unnecessary delays later. Looking over the checklist before you begin will help you know what information is required. Although most questions can be answered with a familiarity of the project, the site, and the surrounding area, some information will have to be obtained from other sources, such as the city or county in which your project will occur. This guide will provide you help in both answering the questions and locating the information you will need. The information you provide will help the agencies analyze your project and decide whether additional studies (i.e. wetland delineation or traffic study) are needed. This information will also be used by the agencies when deciding whether to issue the necessary permits or approvals —to address the gaps and overlaps between other regulations. The checklist is designed to help you think about the possible environmental consequences of your proposal. You are encouraged to consider ways to eliminate or reduce these impacts through changes in your proposal, restoration efforts, etc. .............................................................. Required versus "possible" mitigation should be clearly TIP identified in the environmental document. Mitigation that is being considered or possible is appropriate to identify but must be clearly identified as "possible." Otherwise, any mitigation described is likely to be considered as commitments and conditions of the project. .............................................................. 10 Guidance for Part A As noted earlier, the questions in Part A may be reordered or revised by the lead agency. In that event, the titles used below may assist you in finding the appropriate guidance, despite a change in numbering. For questions not included here, please contact the agency requesting the checklist for additional guidance. 1. Project Name Many projects have names but not all. Residential developments, commercial, and industrial ventures are often named. If the project does not have a name, the clearer response is "none" rather than leaving the question blank. 2. Applicant Name More than one person, company, or agency may be listed here. The project's sponsor(s) or the landowner(s) are more appropriate responses than the name of hired consultants, contractor's, architects, etc. who may be handling applications —although including all three is preferable. 3. Applicant Address and Phone Number At a minimum, include the address and phone number of the preferred contact, but including addresses and phone numbers for everyone listed under #2 is preferable 4. Date Checklist Prepared This date may be used to document when responses were given. This could alert persons that conditions may have changed and protect the applicant somewhat from charges of misrepresentation if applicable regulations are revised, the proposal is altered, new information becomes known, or an unexpected event occurs at a later date. 5. Agency Requesting Checklist If the checklist has not yet been requested, list the agency who you intend to submit the checklist to. For agency proposals, list the agency(ies) that will be lead agency for the action. 6. Timing or Schedule Include information on when construction is expected to begin and end, start of use or operation, expected end of use, and the timing of closure or reclamation. For relicensing of existing facilities/operations, describe the project's history of licensing and operation. The reference to "phasing" refers to where one portion of a proposal is completed or undergoes review and/or approval prior to later stages. Although construction projects typically have stages (grade and fill, utility installation, building construction, etc.) you need only identify them as "phases" if seasons will pass between the stages. Examples include: land division, site preparation, road construction, and utility installation done first, with building construction occurring at some later indeterminate time; or the development of a recreational facility (golf course or resort) followed by later phases such as condominiums, single-family subdivisions, or commercial development on the same or nearby tracts. Guidance for Part A Page 11 7. Future Proposals Known expansions and related proposals that are expected to occur, but have not undergone environmental review, should be identified. It may be possible to incorporate the review of future aspects within the review of the current proposal, saving time and money later. The lead agency makes the determination of what aspects can and should be reviewed at this time. 8. Environmental Information Include reports, studies, or other environmental documents that have been, are being, or will be prepared that provide relevant environmental information about your project, the site, or the area. They may be created to support your proposal, for a similar or related project, or they may have been developed during planning by the city or county, etc. Identify the special reports, studies or plans required by development regulations or submitted with project applications. Examples might be: • Wetland Report • Traffic Study • Geotechnical Study • Archaeological Report • Stormwater Pollution Prevention Plan (SWPPP) 9. Pending Approvals Include any permits, funding, or other approvals that have already been applied for that affect the project site but are not part of the current proposal. Examples include a rezone request, water right application, previous proposal of which this is an addition, etc. A list of common permits can be found on the following page. 10. Permit Information List all approvals or permits from any governmental entity that you know will be needed for your proposal, whether from the agency requesting the checklist or from other governmental entities. Governmental entities include: cities, counties, state agencies, districts, ports, and federal agencies. Include any required certificates or letters of availability for public services or utilities. If you do not know the permits that might be required, the agency TIP requesting this checklist or the Office of Permit Assistance (OPA) ycan help you [360-407-7564, 1-800-917-0043 or ; http://www.ecy.wa.gov/ . OPA can provide applicants and agencies with personal assistance, the Permit Handbook (available online or by request), and an online interactive program "OPAS" that can help you identify permits for your project. Guidance for Part A Page 12 Commonly required permits include but are not limited to: Local City or County Permits: • Building • Preliminary/final plat • Grading • Water system • Shoreline • Right of way • Utility • Site plan review • Septic system • Floodplain development . • Variance (zoning, shoreline, etc.) • Outdoor burning Federal Issued Permits: ❖ US Army Corps of Engineers • Section 10 (navigable waters) • Section 404 (fill in waters) ❖ US Coast Guard • Section 9 (bridges) ❖ National Marine Fisheries/US Fish and Wildlife • Endangered Species Act consultation 11. Project Description State Issued Permits: ❖ Dept. of Fish and Wildlife • Hydraulics project approval • Bald eagle management • Grass Carp • Shooting Preserve ❖ Dept. of Natural Resources • Forest Practices • Aquatic lease • Burning (forest slash) • Reclamation ❖ Dept. of Ecology • Water rights • Well drilling • NPDES • Water quality certification • Stormwater • Underground storage tank certification • Dangerous waste ❖ Air Authority/Dept. of Ecology • New source review, for a business or industry • Notice of intent, for demolition projects Description: Provide a description of the type of project (e.g. retail, land clearing, commercial timber thinning, warehouse), and the actions which would occur (e.g. grade, fill, clear, construct, operate, close, demolish, mine). Provide sizes and/or quantities, if known (e.g. building square footage; site or lot acreage; cubic yards of excavation, grading or fill; number of parking spaces; length of roads or utility lines; etc.). Example: Clear-cut timber harvest on 3 acres of a 10-acre parcel, estimated 3,000 cu yds of site grading with import of additional 1,200 cu yds of fill material, construct and operate a 30,500 sq ft commercial multi -tenant facility with a 900 sq ft paved outdoor garden center, lighted and paved parking for 1,500 vehicles, utility installation including 950-ft extension of both sewer and water lines, onsite stormwater retention/detention facility, and landscaping. 12. Location If multiple addresses and/or parcel numbers apply to the project, you may identify the primary address and parcel number(s) and refer to an attached map or written description that will provide sufficient information for the reviewer to understand the precise location of the project. Including the section, township, and range information is also helpful. Guidance for Part A Page 13 Guidance for Part B 1. Earth a. General site description: Describe the basic shape of the land formation on -site, ignoring structures and vegetation, using terms such as those included in the checklist (flat, rolling, hilly, steep slopes, mountainous, etc.). b. Percent slope: Percent slope is typically measured by professionals with a clinometer. To calculate it by hand: Field measurements or a topographic map must be used to determine the rise and run of the steepest slope on site. [Information on creating homemade tools to measure the rise (height change) and run (distance) can be found on the University of Minnesota Extension Service's Website at www.extcnsion.unin.edu/1. The rise and run are then used to calculate the percent slope with this formula: Percent slope = [Rise - Run] x 100. A 45' angle (where rise and run are equal) would therefore result in a 100 % slope. Ranges of slope are also found in the soil survey books from the U.S. Natural Resource Conservation Service (MRCS) —see 1.c. below. c. Soil types: Information on specific soil types can be obtained from the U.S. Natural Resource Conservation Service soil survey for your site. Soil survey information is available at many city or county departments of community development or universities or other libraries. Soil surveys may also be ordered, when copies are available, directly from the NRCS regional office in Spokane at (509) 323-2900 or 323-2981. d. Unstable soils: As well as steep slopes, signs of unstable soils include evidence of past landslides, mass wasting, erosion (including wind erosion), subsidence, tilting structures, uneven floors, cracked paving, etc. Areas of past fill (landfills, filled wetlands or tidal areas, reclaimed surface mines, etc.), destabilization from vegetation removal, evidence or knowledge of high groundwater or concentrated stormwater infiltration, etc. are further indicators of potential soil non -stability. e. Purpose of fill, excavation, or grading: Examples include: to bring the site level with the street, to level the lot, to fill a low or wet area, to create a pond, etc. Type of fill: Describe the type of materials to be imported to the site, such as large rocks, gravel, sand, clay, top soil, mixed soil and rock, etc. Quantity of fill, excavation, or grading: Quantities of grading, excavating, and/or filling should be given in cubic yards. Professionals may need to be consulted for this information (architect, contractor, etc.). Source of fill: Be sure to include where the fill will come from. f. Erosion indicators: Filling, excavation, grading, or removal of vegetation or other stabilizing ground cover (including demolition of structures), can encourage erosion. Water traveling over or below ground or deflected off smooth or hard surfaces can cause erosion, as well as unprotected soils exposed to wind. g. Impervious surfaces: Include any square foot where rain cannot percolate into the ground such as building footprints, asphalt and concrete areas, covered or capped ground, and lined ditches or ponds. Guidance for Part B Page 14 h. Erosion control: Erosion control methods to defray the potential effects of wind, water, and ice on disturbed soils can include: Minimizing removal of vegetation and/or areas of disturbance, especially in areas of vulnerability such as steep slopes or where there is already evidence of destabilization, both during construction and operation/use; .• Planting or maintaining vegetative cover (consider also how the type of vegetation can affect soil stability —considering root structure, evapotranspiration, and diffusion of wind and water energy); Moistening exposed soils or application of stabilizing compounds to reduce wind erosion; .• Placement of straw, riprap, or other materials to reduce exposure of disturbed soils to the elements. Consider how hard armoring (e.g. bulkheads, riprap) versus soft armoring (vegetation) will affect wind and water energy; :• Placement of roads and structures away from areas of unstable soils or geological hazards; .• Managing stormwater after construction is completed. (Will stormwater collected from large areas of impervious surfaces be discharged directly to the ground at focused locations, released slowly in a diffuse manner, retained on site and discharged directly to surface water, or will it be piped off site?) See also information provided under section B.3. Water. 2. Air a. Air emission types: Dust should be considered a potential air emission if upland vegetation will be removed, or if there will be grading, fill, excavation, rock crushing, demolition, etc. Some types of activities that generate either indoor or outdoor air pollution emissions or the potential to produce an odor nuisance include: • Abrasive blasting • Plating/Anodizing • Asphalt preparation • Printing • Coffee roasting • Rock or material crushing, grinding, or • Composting transport • Concrete batching • Soil or groundwater remediation • Dry cleaners • Solvent or other volatile liquid use or • Fuel dispensing or storage storage • Fuel -fired equipment • Sterilization processes • Landfill • Welding • Manure application and storage • Wood processing • Painting or surface coating If the amount of the emission cannot be quantified (such as from agricultural practices, wastewater facilities, or municipal landfills), describe the source(s), including quantities known or assumed. For example: Liquid manure from X dairy cows will be sprayed on X acres during the months of May through September, and will be collected on -site in an X-gallon capacity dairy lagoon. b. Off -site sources of air emissions and odors: See subsection 2.a above for possible of -site sources. Identify any regional air quality limitations (such as an air quality designated non -attainment area). For information of this type, contact your local Air Guidance for Part B Page 15 Quality Authority or the Air Quality Program staff at the local Department of Ecology regional office. Areas with existing air quality issues (smoke and other particulate matter, ozone, carbon monoxide, odor, etc.) are more sensitive to impacts from proposed projects and may have an adverse impact on some project activities. c. Measures to reduce or control air emissions: Methods that will be used to reduce or eliminate dust or other air emissions include methods to contain, treat, or reduce odors and/or pollutant emissions, such as consistently covering material soon after deposit, placing covers over or aerating wastewater lagoons, use of bag houses or air scrubbers, wetting or otherwise stabilizing disturbed soils, using "clean" fuel/power, recycling solid waste (rather than burning or landfill), etc. 3. Water Note: The Washington Department of Ecology's Water Quality Program has information on their website that may be helpful in identifying water quality issues and improving your proposal. littn:i/www.ecy.wa.eov/programs/wq/wghome.html a. Surface Water 1) Water body on or near the site: Describe (and name whenever possible) any onsite or nearby surface water body, including streams (permanent, intermittent, or seasonal), rivers, ponds, wetlands, lakes, salt water, etc. (Although a distance has not been set by rule, within 300 feet or the width of the floodplain, whichever is larger, may be a good rule of thumb to use for determining "nearby.") 2) Work in, on, or near the water: Include grading, fill, or excavation; installation, construction, or demolition; paving; painting or other maintenance activities; storage of materials; planting or removal of vegetation; etc. Also describe where these activities will take place in relation to the water body. 3) Water body fill or dredge: Describe the quantity, type of material, and the location, including the size of the area to be filled or dredged. Example: Remove 4,000 cubic yards of silt and gravel from the Big River to maintain the navigational channel between river mile (RM) 3.5 and RM 6.2. 4) Surface water withdrawals and diversions: Describe the quantity and location of any surface water withdrawal, even if the use will be nonconsumptive (meaning the same quantity of water is returned to the water body). "Diversions" refer to changes in flow patterns, such as diverting a stream away from a building site or the creation of ponds or inlets. 5) F000dplain: Zone designations are found on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMS). FEMA maps are available through the local jurisdiction (city or county) or by contacting the Department of Ecology's regional floodplain staff. 6) Discharge of waste: Include industrial wastewater; domestic sewerage; agricultural runoff, stormwater drainage from parking lots, equipment storage areas, chemically -treated lawns and landscaping; etc. Describe the source, the likely contaminates, and quantities if known. Guidance for Part B Page 16 b. Ground Water 1) Ground water withdrawals and discharges: Describe any new or increased groundwater extractions, including use or purpose and approximate quantities if known. For water discharges to ground, remember to consider how stormwater runoff collected from impervious surfaces is managed on -site. 2) Waste discharges to ground: Septic systems are a primary source of waste discharges to ground, but unlined ponds or trenches used for discharge or storage of liquid waste (liquid manure, food processing waste, contaminated waters, etc.) should also be considered. Remember to include size/quantities and to describe the nature/characteristics of the waste to the degree known. c. Water runoff (including stormwater): 1) Runoff source and flow: Describe the source of runoff, any intended management systems, and both where and how the runoff will be discharged or allowed to flow to ground or surface waters. 2) Waste or contamination of runoff. In considering whether waste could be carried to ground or surface waters, consider potential sources of contamination (such as parking lots, equipment storage, agricultural practices, lawn and landscaping maintenance, animal waste, treated wood, eroding soils, etc.), any treatment provided, and where the runoff will flow or be discharged. Describe the type/source of potential contamination and the water body or aquifer it is likely to end up in. d. Mitigation for water impacts: Mitigation measures for water quality impacts may include: • Erosion control measures (See section B. Lh above); • Minimizing or avoiding activities within water bodies; • Working in dry conditions where possible; • Providing adequate buffers; • Planting and/or maintenance of native vegetation —including trees and shrubs; • Replacement or compensation for lost functions; • Avoiding or minimizing contamination of stormwater; • Adequate treatment and retention of stormwater; • Maintaining/replacing septic systems or using public sewer systems; • Limiting use of fertilizers and pesticides; • Optimum treatment of sanitary and/or industrial wastewater; • Location or manner of wastewater discharge (diffusion, area of rapid mixing and/or aeration, etc.); • Recycling or treating/reusing wastewater; • Using steel or concrete pilings rather than treated wood; • Planning over -water structures to minimize shading with narrower width or filtering light through glass or grating. Mitigation measures for flooding may include: • Minimizing the footprint of impervious surfaces, • Avoiding construction or fill within wetlands and/or floodplains, • Replacement of lost wetlands, • Retention of natural vegetation —including trees, • Vegetation plantings, • Stormwater management and detention, Guidance for Part B Page 17 • Groundwater recharge versus discharge to surface waters, • Location and design of wastewater discharge. Mitigation measures for impacts to water availability to consider: • Recycle or treat and reuse wastewater, • Use of equipment or methods to reduce water use, • Eliminate or minimize existing water consumption, • Use of alternate source where impact would be reduced. 4. Plants a. Types of vegetation: Information on vegetation types is available from the Washington Department of Natural Resources regional office, the Puget Sound Environmental Atlas, and/or- the city or county. b. Vegetation removal or alteration: In most cases the amount of vegetation that will be lost or altered is most easily described in land area (acres or square footage). Selective removal or alteration of a relatively small number of individual trees or other plant(s) would be an exception. If harvesting timber, you may wish to include information on board feet as well as the acreage involved. c. Threatened and endangered species: A list of threatened and endangered plant species within Washington State is available at http://ecos.fws.gov or by contacting the U.S. Fish and Wildlife Service. d. Vegetation mitigation: Avoiding or minimizing disturbance, plantings (particularly of native plant species), removal of invasive species, and reseeding should be considered as ways to mitigate impacts to vegetation. Protection, replacement, or enhancement of rare or valuable habitat is of particular value. 5. Animals a. Types of animals: Information on the types of animals in your area is available from the local Washington Department of Fish and Wildlife office, TRAX system through the regional Washington Department of Natural Resources office, the Puget Sound Environmental Atlas, and/or the city or county. b. Threatened and endangered species: Washington Department of Fish and Wildlife maintains a listing at http://www.wa.gov/wdfw/ or you may contact their GIS section in Olympia. A list of the federally -designated threatened and endangered animal species within Washington State is available at http://ecos.fws.gov or by contacting the U.S. Fish and Wildlife Service or the National Marine Fisheries Service. Lead agencies may also choose to have applicants complete the "Optional Salmon Checklist' available in several formats at http://www.ecy.wa.l,yov/pi-o(_qaTns/sea/se-pa/forins.litm c. Animal migration routes: Consider birds, fish and other wildlife when identifying migration routes. Examples of areas that should be identified are areas of rare or unique habitat; wildlife corridors; fish -bearing rivers and streams; and lakes, ponds, and other areas where migrating birds are likely to stop. d. Wildlife mitigation: Examples include: Habitat restoration (native plantings; maintaining water quality and hydrology including temperature, stream flow, etc.; protection from human and domestic animal intrusion or noise, light, and glare; etc.); Guidance for Part B Page 18 • Measures to preserve or restore fish and wildlife corridors; • Monitoring or ongoing stewardship of habitat. 6. Energy and Natural Resources a. Types of energy: If different energy types/sources will be used to address separate uses/needs, identify what type will be used for which use (such as natural gas for heating, cooking, and hot water; electricity for all other household needs). b. Solar power interference: In essence, this question refers to shading of nearby properties as a result of the proposal. If this may occur, please describe which properties will be affected and the degree this is likely to occur. c. Mitigation may include: • Choosing materials or energy sources that have been recycled or are renewable and plentiful, • Measures to reduce consumption, • Other measures that will increase availability of the resource now or in the future. 7. Environmental Health a. Environmental health hazards: Describe any existing or suspected contamination at the site. Indicators of possible site contamination include some types of past uses: such as auto repair or wrecking facilities, gasoline dispensing facilities, dry cleaning, municipal dump site, radioactive waste, industrial site, log yard, agricultural uses (fertilizers and/or pesticides), etc. Contact the Department of Ecology's Toxic Cleanup Program in the regional office or headquarters for additional information or assistance in identifying potential or verified contaminated sites, and the type of contamination likely at a site. Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project's development and/or construction, or at any time during the operating life of the project. For example, an auto body shop is likely to use solvents and paints, and produce or generate used cleaning solvents or paint wastes. The use, storage, and/or transport of minor quantities of cleaning supplies, such as to maintain an office building or for residential needs may be listed as a class rather than individual products. Substances used in large quantities, such as in industrial or agricultural processes, should be identified by name. 1) Emergency services: Emergency services include police, fire, spill response, ambulance or aid car, etc. Include the need for specialized services and response. For example, certain types of facilities are required to acquaint fire departments with the toxic materials stored or processed on -site and the special fire -fighting needs of the site. 2) Mitigation: Identify mitigation for existing contamination, if any, and for possible impacts during construction and operation of the project. For possibly contaminated sites, state whether an environmental site assessment has or will be prepared for the site (e.g. Phase I or II site investigation, remedial investigation/feasibility study, etc.). Briefly summarize any actions being taken for additional study or for development of a cleanup plan for contamination or hazardous waste. Contact the Department of Ecology's Toxic Cleanup Program and/or an environmental cleanup contractor for information on appropriate Guidance for Part B Page 19 cleanup and/or containment methods. List any remedial investigation/feasibility study, federal record of decision or state cleanup action plan. (Also list in A.8.) For the project, list any Spill Prevention, Containment and Control Plan (SPCC) or similar environmental, health, and safety plans. (Also list in A.8.) Summarize any plans to contain or address environmental impacts and potential releases in the event of an upset, scheduled or unscheduled shut down, accident or contingency occurring, or if project construction or operations are temporarily or permanently suspended. Also, for these circumstances explain any plans to bypass normal processes or controls. Describe any measures during construction and operations to reduce or eliminate the use or production of hazardous substances. b. Noise: 1) Noise in the area: Consider noises associated with vehicles, machinery, drilling, blasting, crushing, dropping of heavy objects, sports fields, playgrounds, loud music, animals, bells, sirens, whistles, other alarms, etc. 2) Noise from the proposal: See B.7.b.1 above for help with types of noise sources. Truck traffic should be quantified by number and by size of load; construction noise should be described so that the reviewer can understand whether hammering will be the norm, or heavy machinery will be used; etc. 3) Mitigation for noise: Suggestions include: Maintenance or construction of berms and/or vegetated buffers, Siting of noise source(s) away from receptors (human and animal), Limiting hours of operation; Design of structures to absorb noise, Selection of equipment and/or power source to be used. 8. Land and Shoreline Use a. Current uses: Be as specific as possible. The words in the parentheses are examples that give more information than the classifications alone. • Residential (apartments/condominiums, townhouses/duplexes, single-family homes, group home, etc), • Commercial (gas station/mini-mart, restaurant, grocery store, strip mall, super mall, etc.), • Community or public service (school, church, daycare, fire station, etc.), • Industrial (warehouse, light manufacturing, pulp and paper mill, refinery, etc.), • Natural resource (forest land, mining, wildlife preserve, etc.), • Recreational (golf course, country club, resort, park, etc.), or Agricultural (orchard, crop farm, cattle ranch, dairy farm, poultry, etc.). b. Agriculture uses: Include the type of crop or animal raised on the site, as well as how long ago the agricultural use occurred. c. Structures: Include size, number, and use of each structure. d. Demolition: Structures are not limited to buildings, but can include bridges, cell towers, fuel tanks, pipelines, etc. When describing a structure to be demolished, information on size is beneficial. Guidance for Part B Page 20 e. Zoning: Include the allowable density as well as the classification. Contact the city or county that has primary jurisdiction over the site for this information. f. Comprehensive plan designation: Contact the city or county that has primary jurisdiction over the site for this information. g. Shoreline master program designation: If the site includes or lies within 200 feet of a shoreline of the state, provide the shoreline designation (contact the city or county for this information). h. Environmentally sensitive area: Also referred to as "critical areas," these are formally identified in an ordinance adopted by cities and counties. Categories include wetlands, streams and surface water bodies, aquifer recharge areas, frequently flooded areas, geologic hazards, and fish and wildlife habitat conservation areas. It is the ordinance of the city or county where the project is located which applies regardless of whether a permit is needed from that city or county. i. Persons living or working onsite: Unless residential occupancy is known (such as in nursing homes, correctional facilities, etc.) the following occupancy rates may be used to calculate the number of people expected to reside within the following types of housing: ■ 2.8 persons per single family residence; ■ 1.9 per unit in multi -unit housing; and ■ 2.4 persons per mobile home. j. People displaced by the proposal: Describe the current use of the site as well as the number of persons displaced. Include both the people that use the site formally (reside, work, etc.) and informally (recreation, transportation, etc.). k. Mitigation of displacement: Describe any measures proposed to reduce or compensate for the displacement of persons described under question B.8.j. 1. Consistency with plans and land use designations: Describe, if known, how the project complies with existing land use plans and designations or what changes will be required. Beyond those named in section 8 in the checklist, the following are examples of plans and designations that the proponent and agencies may also wish to consider: ■ Local subarea plan or overlay zones ■ State designated harbor ■ Air quality non -attainment area ■ State salmon recovery plans ■ State wildlife plans ■ Watershed management plan ■ Habitat conservation plan ■ Wild and Scenic River designation ■ State or national park, monument, wilderness, wildlife refuge, marine sanctuary, scenic area 9. Housing a. Number of units and income level rating: Number of units refers to the number of apartments or condominiums rather than buildings in multi -residential developments. Set dollar amounts for rating low, middle, and high income housing is not possible due to inflation factors and variability throughout the state. The Washington Office of Financial Management provides information on their website regarding housing Guidance for Part B Page 21 costs and income levels throughout Washington State, derived from the US census. http://-,vww.ofi-n.wa.gov b. Residential units eliminated: See guidance under B.9.a above. c. Housing mitigation: Consider providing some lower income housing within the development. 10. Aesthetics a. Building height and exteriors: Although antennas are excluded, other appurtenances should be measured in stating building height, such as smoke stacks, chimneys, vents, etc. Consider window area in determining the primary building exterior material. b. Views: Include both scenic and non -scenic views that will change. Answer "none" if the appearance of the site will remain unchanged. c. Mitigation for aesthetics: Views valued by persons recreating, traveling, working and/or living in the area should be considered in the design and review of the project. Mitigation may include: • Maintenance or construction of berms and/or vegetated buffers, • Design of structures, • Minimizing view obstructions, • Maintaining the character of the area. 11. Light & Glare a. Types of light and glare: Consider indoor lighting that may be seen through windows, as well as outdoor lighting such as street lights, signage, parking lots, etc. For glare, consider mirrored and unmirrored glass, and unpainted metal surfaces. b. Safety and views: Consider potential safety impacts to motorists, boaters, air traffic, and pedestrians on and off -site; as well as safety and/or view impacts to nearby residents, area workers, tourists, wildlife and domestic animals. c. Off -site sources of light and glare: Consider how light and glare from off -site sources could affect residents or workers during construction or operation of the proposed project. Effects on native or domestic animals also need to be considered. d. Mitigation for light and glare: Mitigation may include: • Maintenance or construction of berms and/or vegetated buffers; • Limiting hours of operation or construction work; • Design or placement of structures to minimize light and glare or view obstructions. Guidance for Part B Page 22 12. Recreation a. Recreational opportunities: Be as specific as possible. Examples include: • Walking, hiking, biking, picnicking • Dirt biking, dune buggies, horseback riding • Play ground, ball field, tennis or basketball courts, golf course • Water park, swimming area or pool, boating, rafting, fishing, beach combing • Amusement park, coliseum, stadium, museum, aquarium, zoo, or other public viewing opportunities • Fair, rodeo, or other public celebration event b. Displaced recreational uses: See information provided under B.12.a. above. c. Recreational mitigation: Creation of new or improved recreational opportunities such as an onsite playground and club house, donation of land for park facility, providing public access to beach, etc. 13. Historic and Cultural Preservation a. Historic register: Identify any places or objects on or adjacent to the project site that are listed or proposed for listing on a historic register. Contact the local jurisdiction or the State Office for Archaeological and Historic Preservation for information. b. Cultural site: Identify any places or objects on or adjacent to the project site that are of archeological, scientific or cultural importance. Contact the local jurisdiction, the State Office for Archaeological and Historic Preservation, use the TRAX system (regional Department of Natural Resources offices), or tribal sources for information. c. Mitigation for historic or cultural resource: Suggestions include: • Avoidance, • Maintaining, or restoring the integrity of the site or landmark to the extent possible, • Relocating the structure or artifact, • Meeting tribal needs for the sanctity of the location. 14. Transportation a. Public streets and highways: Highways or other major arterials listed need not directly access the site but are the major roads likely to be used by employees or residents and for the transport of materials or goods on or, off the project site. b. Public transit: Include details on the type (bus, subway, train, etc.) as well as the distance to the nearest stop or terminal. c. Parking spaces: If parking spaces are intended for other types of vehicles than automobiles, please state the number of each type. Also be sure to note when answering this question when the spaces are being added and when they are being eliminated. d. New roads and street improvements: It would be beneficial to show any new roadways on a map and describe them here (number of lanes, turn lanes, surfacing, etc.), as well as any appurtances such as lighting, stonnwater conveyance, barriers, signage, etc. e. Water, rail, air transportation: Consider increased demand for the transport of raw materials, products, employees, residents, etc. Guidance for Part B Page 23 f. Trips per day: Trips per day is the measure of vehicle trips to or from the project site during a given 24-hour weekday. Many agencies also require information on peak hour trips and it may speed review of your project to include that information on the checklist as well. Only traffic generated by the project need be included. The availability of public transportation, encouragement of car or van pooling, the use of flex -shifts or telecommuting, as well as other traffic mitigation measures may be used to decrease the estimates of traffic generated by the project, but should be detailed in your answer to question B.14.g. below. g. Transportation mitigation: Suggestions may include: • A transportation plan for reducing commute trips per day —particularly during peak hours, • Road improvements (road widening, added signs or signalization, turn -lanes, etc.), • Providing additional parking. 15. Public Services a. Public service demand: In describing increased service demand, include the type of service as well as the reason for increased demand. b. Mitigation may include: • Donation of property (on or off -site) for public uses, • Providing recreational facilities, • Providing on -site security or other emergency services, • Operational or design measures to reduce emergency risks, • ,Impact fees. 16. Utilities a.

The Environmental Review Committee is comprised of the Administrator of the Planning/Building/Public Works Department, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and will then issue its decision (Environmental Threshold Determination). The Environmental Review Committee will either issue a: PW/DevServ/Forms/Planning/ER 7 02/06 Determination of Non -Significance (DNS) -Make a determination the proposal will have no significant negative environmental impacts or; Mitigated Determination of Non -Significance (DNS-M)-Make a determination the proposal, if modified, would have no significant negative environmental impacts or; Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified consultant Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is not required), a public notice of the Determination is printed in the South County Journal and three notices are posted at or near the site. A 14-day appeal period commences following the publication date. At the discretion of the City, a separate and additional 15-day comment period may be added prior to the 14-day appeal period. APPEAL AND RECONSIDERATION. PROCESS FOR DECISIONS: Any person, including the applicant, aggrieved by the threshold determination, may make a written application for reconsideration to the Environmental Review Committee within 14 calendar days of the date of the decision. After review of the request, the Environmental Review Committee may take whatever action is deemed proper.

If any party is still not satisfied after a reconsideration decision has been issued, an appeal may be submitted within 14 days to the Hearing Examiner. An appeal may be filed without requesting reconsideration by the Reviewing Official first, however; it must be filed within 14 days of the date when the original decision was issued. See Renton Municipal Code, Section 4-8-110 for further information on the appeal process and time frames. BUILDING AND CONSTRUCTION PERMIT ISSUANCE AND INSTALLATION OF IMPROVEMENTS: In the City of Renton, a Building Permit must be obtained to build buildings and structures. A Construction Permit must be obtained to install utility lines, transportation improvements and undertake work in City right-of-ways. Building and Construction Permits are separate permits. Applicants may apply for building and construction permits concurrently with their request for a land use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. DEFERRAL OF IMPROVEMENTS: If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings must be submitted to the Development Services Division. The application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an irrevocable letter of credit, set -aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The pufpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain .your answers or provide additional information reasonably related to determining if there may be significant adverse impact.

Development Planning Section Q:\WEB\PW\DEVSERV\Forms\Planning\waiverofsubmittalregs_9-06.xls 09/06 PURPOSE OF SEPA The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, is intended to ensure that environmental values are considered (in addition to technical and economic considerations) by state and local government officials when making decisions. SEPA contains specific policies and goals which apply to actions at all levels of government within the state, except the judiciary and state legislature. The SEPA Rules (Chapter 197-11 WAC) were adopted to implement SEPA and to establish uniform requirements and guidance for compliance with SEPA. SEPA has four primary purposes as listed in Chapter 43.21C RCW: 1. To declare a state policy which will encourage productive and enjoyable harmony between people and their environment, 2. To promote efforts which will prevent or eliminate damage to the environment and biosphere, 3. To stimulate the health and welfare of people, and 4. To enrich the understanding of ecological systems and natural resources important to the state and the nation. The SEPA process starts when someone submits a permit application to an agency or when an agency proposes to take some official action. Prior to taking any action (issuing permits, approvals, etc.) on a nonexempt. project, agencies must follow specific procedures to assure .that appropriate consideration has been given to the environment. The severity of potential environmental impacts associated with a proposed project will determine whether an environmental impact statement is required. If an. environmental impact statement is not issued, a determination of nonsignificance must be issued. After completion of the environmental impact statement or determination of nonsignificance, agencies may act upon the permit application or other approval required for the project. Administrative or legal appeals and challenges concerning SEPA compliance must be linked to a specific governmental action (e.g., permit) and be brought in a timely manner. Early Coordination One of the primary purposes of SEPA is to evaluate the environmental impacts of a proposed project and identify methods to reduce the impacts. If there appear to be major problems with a proposal, the lead agency .1 A-1 should discuss the project with the applicant as early as possible and explain the areas of difficulty. If the lead agency is aware that major changes will be required to allow a project to proceed, the applicant should be given the opportunity to withdraw the project prior to complying with SEPA. A handy tool which has worked for us is the early interagency meeting with the applicant. This can be done either before SEPA begins, during checklist review, or during scoping. Applicants with whom we have worked have responded.quite positively to an early thorough discussion of issues, options, and time frames. Feasibility and critical issues can be identified, discussed and, in many cases, worked out before the process begins. The applicant can then make informed and reasoned choices about show. to proceed. Public Involvement The goal of SEPA is much more than simply procedural. Projects are modified, mitigation is accommodated and the public is made to feel more comfortable in a successful SEPA process. The latter function cannot be achieved by performing the process in a "black box". Indeed, public involvement has been found to be the key to preventing public suspicion of the process. Repeated efforts should be made to involve the public. Whereas scoping and DEIS review have mandated public interfaces, we have found additional efforts very useful. Agency/citizen committees which meet several times with the applicant and the lead agency can give everyone a feeling for the complexities of the issues and an opportunity to participate in the environmental analysis. Informal public meetings have also proved useful. Whatever the form, an open and fluid public involvement process is a key to avoiding polarized positions which can lead to needless and unpleasant conflict. Even when there are strong conflicting differences regarding a decision, SEPA through its public involvement process can provide (at a minimum) a reasonably equal level of understanding of the issues and facts surrounding a proposal. A-2 ACTION (WAC 197-11-704) The.SEPA Rules define ".action" as either project.on nonproject.actions. Project actions involve an agency decision on a specific project ("construction or management activity located in a defined geographic area"). Nonproject actions involve agency decisions on policies, plans, or programs. a Actions are further defined as: "(a). New and :continuing .activities (including'.'projects::.andr:programs) entirely or .partly._.financed, .assisted, ,conducted:; regulated;::licensed, or approved by.' agencies; (b) New or revised agency rules, regulations, plans, policies; or procedures; and (c) Legislative proposals." The first step in the SEPA process is to determine whether -'the -proposal involves an "action". If the proposal meets the definition of action, the next step is to determine whether the project is -categorically exempt (see next section). If the proposal does not fit the.definition of action, SEPA documentation is NOT required. If a private proposal does not require any form of agency approval, the proposal is not an action and SEPA documentation is not required.

The SEPA Rules expand this list of exemptions to include certain other activities which will normally have no impact or.very.minor impact on the environment.(WAC 197-11-800.through 880). n Categorical exemptions are divided into two groups:.::.those:..which..apply..to specific projects, and those which apply to specific:agency;activities. Some°exemptions do not apply if the proposal involves: -discharge torthe water or air, involves a rezone, or is on lands covered by water. Projects may also be exempted if they meet the rules for an emergency exemption in WAC 197-11-880. Categorical exemptions do not. apply if a project:._,..(.l).-is.:..in..a.designated environmentally sensitive area (WAC 197-11-908);.or (2)-consists of.a series of actions, some of which are not exempt, or which together may.have a probable significant adverse environmental impact. If a project is determined to be categorically exempt, .no further SEPA documentation is required and the permit processing:may proceed. Flexible Thresholds Most "categorical exemptions" use size criteria to differentiate between an exempt or nonexempt proposal. The SEPA Rules allow cities and counties to set their own size criteria within a specific range for some types of projects. These "flexible thresholds" must be implemented by ordinance or resolution and specified in the agency's SEPA procedures (WAC 197-11-800(l)(6)). When making a ,threshold determination the responsible official must take into account flexible thresholds established by cities and counties. The city or county should be contacted to determine what level of exemptions have been adopted. Cities or counties that implement "flexible thresholds" are required to send a copy to the Department of Ecology, who will keep a record of these areas. These files may be viewed at Ecology's Headquarters Offices in Lacey. Environmentally Sensitive Areas (ESA) The intent of the "categorical exemptions" was to distinguish types of projects that would not normally have significant adverse environmental impacts from those that would have significant impacts. Under certain conditions. projects.which are normally exempt may have significant adverse environmental impacts. These might include areas with unstable soils, steep slopes, unusual or unique plants or animals, wetlands, etc. C-1 Cities or counties can designate and map areas within their boundaries as environmentally sensitive areas by specifying them in their SEPA procedures and identifying the exemptions which do not apply within those areas (WAC 197-11-908). Once cities/counties designate such areas, they are required to notify the Department of Ecology, who will keep a record of these areas. The responsible official must take any environmentally sensitive areas into consideration when making the threshold determination. A project proposed within the boundaries of an ESA, which would normally be categorically exempt, may NOT be categorically exempt (WAC 197-11-908). The city or county should be contacted to determine whether ESAs have been established. Emergency Exemptions WAC 197-11-880 defines emergency exemptions as cases where an action must b'e undertaken immediately to avoid an imminent threat to public health or safety, public property or the environment. Emergency exemptions should be used only in extreme cases and not to justify poor planning by an agency or applicant. Intervretations. Tips etc - The Court of Appeals decision in Downtown Traffic Planning Committee v. Royer (1980) held that agencies should consider likely environmental effects before applying the SEPA categorical exemptions. If a project will have probable significant adverse environmental impacts, agencies should require full SEPA compliance even through the.project would normally fall within the categorical exemptions. - The total proposal must be identified before the categorical exemptions can be applied: "Total proposal" means all interdependent parts of a proposal, including all proposed phases. This will limit the piecemeal review of projects, and allow an evaluation of cumulative effects of the entire proposal. The SEPA Rules do allow phased environmental review under certain circumstances as defined in WAC 197-11-060(5). - The SEPA Rules do not require any documentation when a project does not meet the definition of action or is categorically exempt. However, we would recommend some kind of note to the file or a note on the permit application to indicate SEPA has been considered. - Agencies should carefully read the entire categorical exemption since some exemptions do not apply on lands covered by water, when a rezone is required, etc. - WAC 197-11-800(2)(f) - The Office of Archaeology has provided an interpretation of "recognized historical significance" in this exemption. Specifically: "...recognition must be formal and conferred by a body with authority and expertise in what might constitute historical significance. To be more explicit, ... a property listed in the State or National Register of Historic Places, or listed in a local register or historic properties...." C-2 •F; - WAC 197-11-800(2)(e) - Ecology considers the exemption for additions or modificatons to buildings to apply to any additions where the existing floor area plus the area of the new addition is less than the square footage exempted under 800(1) for minor new construction. If an existing building was not exempt at the time of construction, any additions to .the building would not be exempt. However, WAC.197-11-800(3) exempts the minor repair, remodeling (not additions) or maintenance activities which would not change the use of the building (except on lands covered by water). - WAC 197-11-800(2)(g) - Underground storage tanks..- Ecology has in2e r-preted this.:exemption to apply to.the total -capacity of.all.:tanks.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the :agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be ;.done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Introduction This report presents the results of our wetland delineation and critical areas study regarding the 1601 NE 24th Street property (hereon referred to as the Site) that lies west of NE 24th Street, between High Avenue NE and Jones Avenue NE, parcel number 3344500220, in the City of Renton. The site is nearly level with a seasonal stream running diagonally across the site from near the northwest corner to the southeast corner. The objective of the study was to delineate wetlands, to evaluate their functions and values, and determine the classification and buffer requirements of the stream and wetlands. 1.1 STUDY AREA DESCRIPTION A single-family residence and associated out -buildings are present at the northwest corner of the 44,044 square foot (1.01-acre) parcel. An unnamed, seasonal, stream flows diagonally across the site from near the northwest corner to the southeast corner; although flow was present in the stream on the date of the site visit on August 23, 2004, due to the sluggish nature of these flows it is anticipated that the stream would normally dry up during early fall. Palustrine forested wetlands are associated with the stream. The site, with the exception of the residence mentioned above, is undeveloped. Review of 1990 aerial photos show that the young trees and blackberries that cover the non - wetland areas of the site have become established since that date. 2. Methods On August 23, 2004, Ms. Celeste' Botha with The Riley Group, Inc. (Riley) examined the study area for indicators of wetlands. Wetlands were identified based on the presence of hydrophytic vegetation, hydric soil, and wetland hydrology using the routine method outlined in the 1997 Washington State Wetlands Identification and Delineation Manual (Washington State Manual), and following City of Renton regulations. During the study area evaluation, two detailed sample plots were located in distinct representative vegetation units in order to characterize the wetland and non -wetland communities. Because there are only two plant communities on the site, these two points were deemed sufficient. Field observations at each sample plot were compiled on preformatted Wetland Data Sheets. 2.1 VEGETATION Vegetation was evaluated across the study area to determine the presence of hydrophytic plant communities. Plant communities are considered hydrophytic when more than 50 percent of the dominant species in the plant community have a wetland indicator status of facultative (FAC+, FAC, and FAC-), facultative wetland (FACW+, FACW, and FACW-), or obligate wetland (OBL), as listed in the Alational List of Plant Species That Occur in Wetlands, Region 9 — Northwest (Reed, 1993 and 1988). The indicator codes for plant species are noted in Table 1. Table 1. Plant Indicator Codes Frequency of Occurrence m Indicator Code Wetlands (under. natural conditions , Obligate Wetland (OBL) — occur almost always in wetlands >99% Facultative Wetland (FACW*) — usually occur in wetlands 67-99% Facultative (FAC*) — equally likely to occur in wetlands or 34-66% non -wetlands Facultative Upland (FACU*) — usually occur in non -wetlands 1-34% Obligate Upland (UPL) — occur almost always in non -wetlands <1 Not Listed (NL) — no indicator status * Note: FACW, FAC, and FACU also have + and — values to represent species near the wetter end of the spectrum (+) and species near the drier end of the spectrum (-). Dominant species were recorded as species comprising more than 20 percent of the plant community in each stratum (tree, shrub, and/or herb layer). 2.2 Soms Anaerobic (saturated) conditions cause hydric soils to form certain characteristics that can be observed in the field. Hydric indicators include: the presence of a matrix chroma of 1 or less in unmottled soil or 2 or less in mottled soil, gleyed soil, organic soils (peats and mucks), and the accumulation of sulfidic material. • Soil pits were dug in each data plot, using a shovel to depths of 16 to 18 inches below ground surface (BGS). Soils textures were characterized using Natural Resources Conservation Service protocol, and examined for hydric indicators as described by the Washington State Manual. Soil colors were identified using a Munsell soil color chart (Kollmorgen Corporation, 1988). Depth. of soil saturation was recorded for each plot. Wetland Data Sheets are included in Appendix B. Several secondary plots were examined across the wetland/upland boundary in order to determine the approximate boundary line, although data forms were not completed at the secondary plots. The secondary plots were used to examine similarities or differences in soils between major data plots and to establish mapped soil unit boundaries. 2.3 HYDROLOGY At each data plot, observations of direct and indirect wetland hydrology indicators were evaluated and recorded. Under normal conditions, hydrologic indicators are used to determine if the hydrology is either currently present or can be inferred from the guidelines provided in the Washington State Manual. These indicators include: recorded data, visual observation of inundation or saturation, watermarks, drift lines, sediment deposits, drainage patterns, local soil survey data, oxidized root channels, and water - stained leaves. 2.4 FUNCTIONAL ASSESSMENT In addition to the delineation, a general assessment of the functions of the wetland system was completed using the Semi -Quantitative Assessment method. Wetland community types were classified according to the Classification of Wetlands and. Deep Water Habitats in the U.S. (Cowardin et al., 1979). 3. Wetland Study Results Riley identified and delineated one wetland on the site (Figure 2). A summary of the vegetation, soils, and hydrology observed in the wetlands and the adjacent on -site upland is presented below. 3.1 DELINEATION 3.1.1 VEGETATION The on -site portion of this wetland system associated with the unnamed stream is palustrine forest dominated by black cottonwoo8 (Populus balsamifera), Pacific willow (Salix lasiandra) and red alder (Atnus rubra) in the overstory, and Himalayan blackberry (Rubus procerus) in the understory. Hardhack (Spiraea douglasii), salmonberry (R. spectabilis), Scouler's willow (S. scouleriana), red -osier dogwood (Corpus stolonifera), black twinberry (Lonicera involucrata), stink currant (Ribes bracteosum) and holly (Ilex sp.) are each present scattered throughout the wetland in minor amounts. The herb layer, where present, is comprised of scattered small -fruited bulrush (Scirpus microcarpus), creeping buttercup (Ranunculus repens), lady fern (Athyrium filix femina), and common horsetail (Equisetum arvense). This vegetative community is represented on data form 1. The upland forest community is comprised of similar but mostly immature species in the canopy, and here too Himalayan blackberry dominates the understory. Cascara (Rhamnus purshiana), Indian plum (Oemleria cerasiformis), and mountain ash (Sorbus aucuparia) are present in the shrub layer. Ivy (Hedera helix) is a common component in the herb layer. This vegetative community is represented on data form 2. �c 3.1.2 SOILS The site is mapped Indianola loamy fine sand 4 —15% slopes (InC) in the Soil Survey of King County Area. The Indianola series is a non-hydric soil made up of somewhat excessively drained soils that formed under conifers in sandy, recessional, stratified glacial drift. In a representative profile, the upper 30 inches is brown, dark yellowish - brown, and light olive -brown loamy fine sand. This is underlain by olive sand that extends to a depth of 60 inches or more. Soils varied at the two wetland data points. At DP 1, the soil was black mottled loam to the depth of evaluation (16 inches). At DP 2, soil was 10YR4/2 non -mottled, dry, very compacted sandy loam to the depth of evaluation (refusal at 10 inches). 3.1.3 HYDROLOGY Direct evidence of wetland hydrology (i.e., inundation or soil saturation) was observed only in areas adjacent to the stream on the date of the site visit in mid -August. However, indirect evidence of hydrology, in the form of evidence of recent flooding, was present throughout the area designated wetland. Hydrology was also implied at DP1 from soils, topography and vegetation. Topography and the shrub -layer composition were the most significant indicators used in determining the wetland boundary. 3.1.4 WETLAND DETERMINATION Based upon direct or indirect evidence of all three wetland parameters, a palustrine forested wetland is associated with the stream on the subject site (Figure 1). 3.2 WETLAND FUNCTIONS AND VALUES The wetlands provide low wildlife habitat value except to birds primarily due to their size and location in a heavily urbanized environment. Moderate structural and species diversity increases this function primarily for bird habitat, and association with the stream has the potential to provide moderate water quality improvement, storm and floodwater attenuation and storage, and hydrological support. The wetlands' groundwater exchange potential is unknown at this time. Because the wetlands are located on privately owned land, the wetland has low potential to provide cultural and educational opportunities. 4. Regulatory Implications As no wetlands impacts are proposed for the subject site, no state or federal wetlands regulations pertain to this project. The Washington Department of Fish & Wildlife regulates activities within the ordinary high water mark of streams. No such activities are proposed for the subject property. 4.1 CITY OF RENTON REGULATIONS 4.1.1 WETLANDS The wetland on the subject site meets the criteria as a forested Category 3 wetland. The wetland classification is based upon the wetland size (greater than 5,000 square feet); severe disturbance, including the dominance of invasive species within the wetland, specifically Himalayan blackberry; the presence of fill material within the wetland and its buffer to the south and west as well as roadway fill on the north and east property lines, and; ditching of the stream at the southeast corner (just off -site). Category 3 wetlands are protected with 25-foot buffers. 4.1.2 STREAMS The City of Renton is in the process of revising the municipal code sections related to streams. The City of Renton defines stream, creek, river, or water -course as, "any portion of a channel, bed, bank, or bottom waterward of the ordinary high water mark in which fish may spawn, reside, or through which they may pass, and tributary waters with defined beds or bank which influence the quality of fish habitat downstream. This includes watercourses which flow on an intermittent basis or which fluctuate in level during the year, and applies to the entire bed of such watercourse whether or not the water is at peak level. This definition does not include irrigation ditches, canals, stormwater runoff devices, or other entirely artificial watercourses, except where they exist in a natural watercourse which has been altered by humans or except where there are salmonids." At this point in time, there is neither a stream classification system nor buffer requirements in the municipal code. The on -site stream is unlikely to support salmonids. 5.

FCIFIERS[]N SNURT PLAT - ! :< FAGE 4 OF 1 2 GEoDatum - Section 1 - Project Overview The proposed Roberson Short Plat consists of approximately 44,680 square feet (1.028 acres) of land located at the intersection of NE 24th St and 108t Ave SE. This project is for subdivision of an existing single family parcel into 4 lots. The proposed project is located in the SE Quarter of the NW Quarter of Section 5, Township 23N, Range 5E, WM, King County, Washington and is shown on the vicinity map below. VICINITY MAP There is currently one residential structure on the property. The project proposes to keep the existing structure and develop the property into a 4-lot short plat project with the associated frontage improvements and underground utilities. Currently the property drains directly into a stream that bisects the property. The developed site will discharge all stormwater not infiltrated to this stream. The hydrology to the wetlands associated with this stream will be maintained by directing surface flows to the wetlands from the new lots. This project adds less than 5000 s.f. of pollution generating impervious surfaces and therefore water quality controls will not be required. ROBERSON SHORT PLAT - TI R PAGE 5 OF 1 2 GEoDatum:-, The existing ground cover is predominantly second growth forest with some grass and landscaping. The proposed development will preserve much of that ground cover in it's existing state within the wetlands and associated buffer.

ROBERSON SHORT PLAT - TI R PAGE 6 OF 1 2 GEoDatum S,,,tion 2 - Conditions and Requirements Summary The following summary describes how this project will meet the eight "Core Requirements" and the "Special Requirements" that apply: Core Requirements 1 through 5 1. Discharge at the natural location: Currently the property drains directly into a stream that bisects the property. The developed site will discharge all stormwater flow to this stream. The hydrology to the wetlands associated with this stream will be maintained by directing surface flows to the wetlands from the new lots. 2. Off -site Analysis: A Level 1 off -site analysis was completed for this project and is contained in this report under Section 3. 3. Flow control: The proposed infiltration facilities will be sized based on the requirements of Section 4.5 at the time of building permit application. The flow from additional impervious surfaces in the right of way is not detained and is allowed to bypass. It is anticipated that the infiltration of 100% of the roof runoff will compensate for the bypass flow. 4. Conveyance system: Flows will be conveyed using the existing stream as well as within culverts provided for the new curb and gutter improvements anticipated as a part of this project. Upstream flows will not be impeded or redirected as part of this project. 5. Erosion and sedimentation control: TESC plans will be submitted along with the engineering plan submittal. Erosion and sedimentation control will be provided along the wetland buffer and also within the street right of way during the construction of any improvements.

The subject property currently surface flows to an unclassified stream that bisects this property from south to north. Adjacent road drainage flows into roadside ditches that convey the flow to the stream near the point that it exits the property. At the north end of the property a 25" culvert conveys the stream under NE 24th St. From that point the stream continues north along the 1-405 right of way to the point where it is tight -lined under the freeway and continues to the west into Puget Sound. Not all portions of the stream were accessible due to locked gates and fences, however, all portions which were visible showed no signs of erosion or overtopping. All banks were well vegetated and stable_ All culverts flowed freely and did not contain significant amounts of sediment. There was some sediment observed in the culvert under NE 24th St which should be cleaned out in the course of completing the improvements for this project. The following are several photos taken at the site during the visit: Photo 1 — This is looking north from the south side of the property where the stream enters the subject property.

Dear Mr. Jordan: In response to our pre -application meeting and subsequent phone conversations on October 2, 2003, 1 am submitting a variance request for the Bartell Short Plat Application. The variance request is from the stream buffer requirements of the Renton municipal code, for the construction of frontage improvements along Jones Road. I offer the following responses to the applicable Variance Criteria: Applicant suffers Undue Hardship — The existing stream runs parallel to Jones Road and the subject property. The existing Jones Road right-of-way is currently within the existing stream buffer. The applicant is being required by the City to construct additional frontage improvements as part of the development proposal. The required improvements will be within the existing right-of-way and proposed stream buffer. The applicant has no opportunity to avoid these impacts. • Detrimental to Public Welfare — The proposed variance will not be detrimental to public welfare or the environment. The existing right-of-way lies within the proposed stream buffer but is separated from the stream channel by a drainage ditch and a natural wall of large trees. This wall of trees forms the east bank of the drainage ditch and the west bank of the stream channel. All proposed improvements will take place on the west side of the tree wall, which will protect the existing stream. The required improvements will be the minimum allowed by code and all construction will be in accordance with best management practices. As part of storm water improvements to the site, the existing stream channel will be enhanced (Please refer to the Buffer and Channel Enhancement Plan). 03.255 • Page 2 December 2, 2003 In addition to the minimal and mitigateable impacts to the stream channel, the required frontage improvements will have a beneficial impact on both vehicular and pedestrian safety along Jones Road. Not a Grant of Special Privilege — The applicants are being required to construct frontage improvements for the proposed plat in accordance with the applicable city regulations. Granting of this variance request will allow the applicant to comply with the applicable codes and standards. Failure to grant permission to construct the required improvements within the buffer will necessitate a variance from the applicable City Road Standards. Minimum Variance Required - The applicants are being required to construct frontage improvements for the proposed plat in accordance with the applicable city regulations. The applicant proposed to meet the minimum required frontage improvement standards with little or no deviation from the standard City details. The applicant is not requesting permission to do any additional improvements. The proposed variance would be the minimum necessary to meet the current standards.

Further, I concur that the current City regulations require only a 25-foot buffer area along the subject stream corridor. Please be advised that the City is in the process of reviewing its regulations relative to stream buffer widths and these requirements could increase in the future. While your proposal will be vested under the regulations in effect at the time of the City's acceptance of a complete preliminary plat application, it is possible that the City or other reviewing agencies could require increased setbacks as habitat impact mitigation as part of the project's required environmental review. hope this determination assists you preparing your preliminary site development plans.

Burnstad, Senior Biologist A�[bLmy6A PROJECT NAME: Bartell Residential Subdivision PROJECT NUMBER: WD 2003032 Hans - This memo is a follow-up to our July 9, 2003 field reconnaissance at the Bartell property in Renton, Washington. The purpose of the field reconnaissance was to determine the characteristics of a human -made water feature located in the southwest corner of the subject property (see attached site map). On July 9, 2003 I visited the Bartell site with you and we investigated the human -made pond and stream channel located in the southwest corner of the subject property. Our evaluation included a review of the outlet of the pond located on the east side of 108`h Avenue SE (Jones Avenue), the culvert under Jones Avenue, and the open channel on the property located west of the Bartell site. We also reviewed the channel condition upstream (south) of the subject property at the point where the stream flows into the human -made pond on the subject property. Finally, we reviewed the pond (water feature) located on the property immediately south of the Bartell site. Findings The human -altered stream channel on the property immediately south of the Bartell site was in a concrete -lined pond with concrete sidewalls that is approximately 45 feet to 50 feet long and 15 feet to 20 feet wide. The stream flowing into the upstream end of the pond was contained in a 15-inch diameter CMP (corrugated metal pipe). The pipe appeared to contain the stream flow upstream of the pond to an unknown south of the Bartell parcel's south boundary. The stream appeared to be tight -lined from the pond inlet all the way to the south side of NE 20`h Street. Draft Memo to Mr. Hans Korve, Planner — Page 1 Bartell Project, Renton, Washington The surface water out of the concrete -lined pond on the property south of the Bartell site flowed into and through a larger human -made pond located on the Bartell property. The shape of this larger pond was somewhat trapezoidal approximately 40 feet wide and 50 feet long at the widest and longest dimensions. The area around the pond has been manipulated and includes a garden, native and non-native groundcover and shrub species, and large cottonwood, cedar, and willow trees. The plant community surrounding the pond was indicative of wetland characteristics but an evaluation of the soils indicated there were no hydric soils around the pond. The pond had nearly vertically sidewalls of native soil but the pond bottom material appeared to be accumulated gravel and silt over the top of a concrete bottom. There was large gravel to cobble and quarry spalls (rip -rap) along the toe of the steep sidewalls that was, according to the owner, imported to protect the pond bank above the concrete bottom. There was a pipe/sprinkler in the center of the pond which, according to the owner, was used to aerate the pond. There was also a 1.5-inch diameter black plastic pipe that was used to withdraw water from the pond for irrigation. The stream flow was most evident along the western edge of the pond. There was a 12-inch diameter concrete pipe located in the northwest corner of the pond that was acting as a control structure to restrict flow and maintain the water surface elevation of the pond. The water flowing out of the pond flowed into a ditch along the east edge of Jones Avenue and entered an i 8-inch CHIP under Jones Avenue. This culvert direct stream flow under Jones Road and into the open channel on the developed residential property that is west of the Bartell site on the opposite side of Jones Avenue. The stream channel is rip -rapped and channelized through the property on the west site of Jones Avenue. The stream flows across this property in a northwesterly direction and enters an undeveloped property in the southwest quadrant of the Jones Avenue/NE 24`" Street. From the undeveloped property (which is essentially a regulated wetland) the stream flows in a northerly direction under NE 241' Street along the east side of Interstate 405 and then northeasterly to May Creek. City of Renton Regulatory Implications Following the reconnaissance I reviewed the Renton Municipal Code to determine if the human - made feature on the subject property would be a "regulated" wetland within the City of Renton (City). Based on my review of Title IV, Chapter 3, Section 3.050.A.7 and Section 3.050.B.7 it appears that the human -made feature (the pond) is not a regulated wetland within the City, because it is a human -made feature. Based on my evaluation of the code, however, the stream is regulated within the City and would be a Category 3 Wetland requiring a 25-foot native growth buffer between the stream and any developed areas. Although the City code does not specifically speak to streams, the definition of wetland categories appears to include streams. The code does not speak to where the buffer width is measured from, but based on my experience in other jurisdictions I would suggest that the buffer width is measured from the ordinary high water mark. Draft Memo to Mr. Hans Korve, Planner — Page 2 Bartell Project, Renton, Washington In addition, I suspect there would be a building setback between and permanent structures and the landward edge of the stream buffer, but I did not review the zoning code to determine the width of that setback area. It would be prudent to contact the City regarding building setback requirements if you are unable to find the specifications in the City code. Recommendations for Land Use Based on my field observations and my interpretation of the City code it appears that the human - made pond could be filled as part of the proposed development. The stream channel would have to remain open, however, and would very likely have to be restored (enhanced) as part of the development process. I would recommend the following as alternatives for dealing with the pond as part of the development process: ALTERNATIVE 1: Leave the pond as it currently exists and measure a 25-foot buffer based on a project of the ordinary high water mark at the southwest comer of the property where the stream enters the pond and at the northwest corner of the pond where the stream exists the pond. ALTERNATIVE 2: Fill the pond except for a stream channel along the west edge of the pond (see attached sketch). The stream channel should be designed to convey the anticipated 100-year peak flow or the maximum flow capacity of an 18-inch diameter CMP with a water surface elevation 36 inches above the pipe invert elevation. The stream channel design should assume the 18-inch culvert has inlet control and a vertical headwall with 45-degree wing -walls at the entrance of the culvert. The filling of the pond would include the removal of the 12-inch diameter pipe that currently controls the pond outlet. The channel would have to be enhanced from the inlet end of the pond at the south property line to the outlet end of the pipe currently in the northwest corner of the pond. The channel would have a bottom width approximately 18 inches to 2 feet wide, a depth of approximately 3 feet, and a top width of approximately 14 feet to 20 feet. The side slope grades (horizontal distance ) of the channel should vary from to as steep as 2:1 and as flat as 4:1. The side slopes (streambanks) would have to be revegetated with native plants (trees, shrubs, and groundcover species). ALTERNATIVE 3: Leave the pond open for use as a retention/detention pond (see attached sketch). Remove the 12-inch diameter culvert at the outlet end of the pond. Leave the existing culvert under Jones Avenue in place. Construct an earth berm along the eastern edge of the stream channel to separate the pond from the stream channel. The berm would have to be constructed to allow a channel design as described in Alternative 2 above. The RID pond would have an outlet control structure that would discharge into the stream channel at or very near the point where the stream channel currently leaves the subject property adjacent to Jones Avenue. Draft Memo to Mr. Hans Korve, Planner — Page 3 Bartell Project, Renton, Washington ALTERNATIVE 4: Implement Alternative 3, but replace the culvert under Jones Avenue with a new culvert in the location shown on the attached sketch. The length of stream that would have to be restored or enhanced within the project area would be shorter so there may be a need to do some enhancements within the Jones Avenue right-of-way on the downstream side of the new culvert to provide sufficient mitigation. Other Regulatory Imolications All of the proposed alternatives would have to be reviewed and approved by the City of Renton. The City would probably require that the preferred alternative be evaluated as part of the SEPA process being completed for the overall proposed project. It would be advisable to meet with the City of Renton to discuss the Alternatives described above before the preliminary design for the project is prepared and submitted to the City for review and approval. In addition, implementation of any of the alternatives except Alternative 1 would require a Hydraulic Project Approval (HPA) from the Washington Department of Fish and Wildlife (WDFW). WDFW requires a SERA determination from the lead agency for the project before they will issue an HPA. The Washington Department of Ecology (WDOE) may require a 401 Water Quality Certification if the project is implemented at a time when the stream is flowing. It would appear that in "normal" years there is some flow in the creek throughout the year. I would advise contacting the owner and the surrounding neighbors to see if they have knowledge about stream flow during the late summer and early fall. With a large wetland complex and springs at the headwaters of this stream there may be year round flow in all years. I do not believe that either the U.S. Army Corps of Engineers, Regulatory Branch (Corps) or WDOE will take jurisdiction over the pond if the City determines that the pond is human -made and regularly maintained. Be aware, however, that both WDOE and the Corps can assert regulatory authority over the pond, if they choose to, since it is not isolated and it is a tributary to Lake Washington. That concludes the summary of the findings, regulatory implications, and alternative approaches to dealing with the pond on the Bartell site.

Burnstad, Senior Biologist PROJECT NAME: Bartell Subdivision, Renton PROJECT NUMBER: dmp Project No. I Watershed Dynamics Project No. 2003032 Per our previous conversations I have prepared the attached details for the stream restoration project associated with the proposed Bartell Subdivision in Renton. The objective of the stream restoration project is to re-establish a defined stream channel in the area where a human -made pond essentially obliterated the defined stream channel. The attached details show the existing condition (Figure 1), the proposed channel alignment and grading plan (Figure 2), a typical x-section showing bank toe revetment (Figure 3A), a typical x- section showing the stream channel and 25-foot buffer on east side of channel (Figure 3B), and a stream materials specification sheet. The hand -drawn details are suitable for preliminary review by the City of Renton (City), but will need to be converted to an AutoCAD format following the City's review and comment. Plan Specifics Stream Gradient: The proposed grading plan includes removal of the existing culvert at the outlet of the human -made pond. The stream (see Figure 2) is graded at a constant 1.5 % to 2% grade from the south property line to the inlet of the existing 18-inch culvert under Jones Avenue. Grade control will be established by installing rock weirs at elevation 240.5, elevation 241.0, elevation 241.5, and elevation 242.0 at specific points along the stream channel. The grade control structures will have a top elevation equal to the channel invert at each installation point. These structures will reduce streambed material mobility and will allow formation of small pools. Installation will be directed by the Project Stream Habitat Specialist. c. . Memo to Hans Korve - February 1, 2004 - Page I Bartell Subdivisn - Stream Restoration Project Downstream Culvert and Ditches: There is an existing 18-inch diameter corrugated metal pipe (CMP) or culvert under Jones Avenue downstream of the project site. There are also existing open drainage ditches adjacent to the east side of Jones Avenue, between the Bartell property and the east edge of pavement that drain to that 18-inch culvert. These features were not altered as part of this design and only the 18-inch culvert and headwall are attached shown on the detail sheet. I am aware there are proposed street improvements associated with the project and understand the stream section between the Bartell's west property line and the existing edge of pavement may change once the civil plans are approved. Any changes in the stream channel restoration design made necessary by the approved street/frontage improvements will be incorporated in the design after the civil drawings have been approved. If the channel length is reduced as a result of City approved street improvements and the invert elevation of the culvert under Jones Avenue remains essentially the same the stream channel gradient will change (increase). An increase in channel gradient will increase stream velocities, which will in turn increase the risk of channel scour. To reduce or avoid the risk of increased channel scour the aforementioned grade control structures will be installed as step -weirs, which will reduce the affective gradient and peak flow velocities. Step -weirs result in the formation of a plunge pool on the downstream side of the rock weir. The pools function to dissipate stream energy in a vertical rather than horizontal direction resulting in reduced bed and toe scour. Design Flow/ Channel Capacity: Based upon field investigations and anecdotal information I am not aware of evidence indicating the culvert under Jones Road has been overtopped by high flows generated in this drainage. The project site is less than 1 mile downstream of the headwaters of the tributary and the contributing basin tributary to the site is relatively small with numerous small wetlands that tend to attenuate high flow events. The flow capacity of the 18-inch CMP under Jones Road is approximately 12 cfs when the headwater to culvert diameter ratio is 2:1. This flow capacity would occur when the water surface elevation was 18 inches above the top of the culvert. The roadway would be overtopped if the water surface reached approximately 30 inches above the top of the culvert, an unlikely scenario given the configuration of the roadside ditches and other off channel storage opportunities associated with the stream. I used 13 cfs as the design flow for the attached stream channel design. Assuming a 2% grade, a roughness coefficient (n) of 0.055 for the channel, a 2-foot channel bottom width, and 1:1 side slopes (to an elevation 1 foot above the channel I.E.), I determined the channel capacity to be approximately 13 cfs when the channel flow has a depth of 1 foot. The average velocity would be slightly greater than 3 fps, which will mobilize silts, sands, and small gravel. This may be a concern because there is no streambed gravel recruitment source upstream of the project site. To compensate for this issue I am proposing the streambed gravel used for this project meet the specifications of the "Transition Mix" shown on the attached stream materials list. In addition, the bed control structures will help reduce unwanted bed scour. Memo to Hans Korve — February 1, 2004 — Page 2 Bartell Subdivisn — Stream Restoration Project Streambed/Stream Bank Gravels/Soil: As noted above the streambed gravels to be installed in the project areas will meet the transition mix specifications. The streambed will be will be over - excavated to allow 1-foot of gravel to be placed in the channel bottom to attain the design streambed gradient. The transition mix will be carried up the stream banks from the toe of the bank to an elevation approximately 0.5 feet to 1 foot above the channel bottom elevation (see Figure 3A). From the upper limit of the streambed gravel to an elevation 18 inches to 24 inches above the top of the streambed invert elevation the stream bank mix will be installed. Stream bank mix is a combination of spawning mix and organic soil (see attached specification sheet). This creates a gravelly bank material that when eroded will contribute streambed gravel to the channel. Stream Bank Toe Revetment: In those areas on the outside of the channel meander, where stream velocities will be the greatest, I have designed stream bank toe revetment to prevent or significantly reduce bank erosion and channel migration. In most natural streams I would be less likely to add this feature to the channel design. For this project, however, channel migration is not an option because of the site design constraints and potential risk to the adjacent built environment. The large rocks placed at the toe of the stream bank will be bedded a minimum of 6 inches below the stream channel invert elevation. I would highly recommend the toe rocks be bedded between 12 inches and 18 inches below the streambed invert elevation if possible. This is added insurance to reduce the risk of toe scour under the large rocks and degradation of the revetment over time. Stream Bank Construction: The proposed plan (see Figure 3B) shows 1:1 slopes to an elevation 1 foot above the streambed elevation and 3:1 slopes from the top of bank to the outer edge of the stream buffer. On the east side of the stream channel, where the human -made pond will be filled, there may be a need to use soil -filled soft gabions (or other engineered retaining structure) on the back (east) of the outer edge of the east stream bank to retain the fill that will be placed to fill the human -made pond located the east of the proposed stream channel. Soil -filled soft gabions would be preferred because they can double as a planting medium and they can be constructed to conform to the 1:1 or 3:1 side slopes as well as the steeper slope behind the rock revetment. If the soil -filled soft gabions are required I will provide another detail and a written construction sequence for inclusion in the plan set. Large Woody Debris Placement: As noted on the stream channel design detail sheet (see Figure 2) large woody debris will be placed in the stream channel. Large woody debris will also be placed in the buffer area. The placement of the large woody debris will be directed on site by the Project Stream Habitat Specialist. A complete list of large woody debris requirements will be provided as part of the final design. Buffer Planting: The stream buffer and upper stream banks will be re -vegetated with native plants after the construction of the physical features has been completed. No planting details have been included in this design information package. Planting details will be prepared after the physical design features have been reviewed and approved by the City. If you have any questions regarding these attached details, please call me.

STREAM CHANNEL CONSTRUCTION MATERIALS GENERAL DESCRIPTION ROCK/GRAVEL MATERIALS The amount of large rock (large geologic material or LGM) used in a stream channel restoration/relocation project vanes considerably with the site conditions and the need to stabilize bank materials. In all projects, however, there is a need to import certain materials to provide habitat features suitable for use by salmonid fishes and the other aquatic organisms frequently found in salmonid streams. Listed below are the specifications for various geologic materials used in habitat restoration projects: Large Geologic Material (LGM): 1.5 to 3.0 ft. long axis 1/2 ton to 2 tons Small Geologic Material (SGM): 0.5 to 1.5 ft. long axis 75 pounds to 1000 pounds Quarry Spalls: 4" to 12" ripped rock Railroad Ballast: 2" to 4" ripped rock The following mixes are composed of round rock, are shown in percentage by volume, and should be thoroughly mixed: Plunge Area Mix: 12" to 24" dia. Pool Mix: 40% = 4" to 6" dia. 30% = 6" to 9" dia. 20% = 9" to 1' dia. 10% = 1' to 2' dia. Spawning Mix: 5% = 0.25-0.50 inch dia. 15 % = 0.50-0.75 inch dia. 25% = 0.75-1.00 inch dia. 25 % = 1.00-2.00 inch dia. 20% = 2.00-4.00 inch dia. 10% = 4.00-6.00 inch dia. Transition Mix: 60% = pool mix 40% = spawning mix Bank Mix: 60% = spawning mix 40% = soil (augmented) FOR AGENCY USE ONLY Purpose of Checklist: The State Environmental Policy Act (SEPA), chapter 43.21 C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions.

Give brief, complete description of the proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The proposed preliminary short plat will be located on 1.72 acres located on tax parcel 334390-3600. The project will subdivide the property into 9 single-family residential lots, open space and access tracts. Applicant will provide frontage improvements along Jones Road and NE 24"' Street in accord with City Road Standards. Applicant proposes to enhance the existing stream channel in the southwest corner of the project and integrate the existing man-made pond into the proposed storm water facility. The owners existing home on the proposed lot #7 will remain. All of the associated out -buildings are proposed for removal. 12. Location of the proposal. Provide a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if available. The subject proposal is situated on 1.72 acres, located within the jurisdictional boundaries of the City of Renton in the NE'/. of Section 5 Township 23 North, Range 5 East W.M. The site is located on parcel 334390-3600. The current address is 1725 24"' Street, Renton. Please refer to the Preliminary Plat map for the legal description, site plan, vicinity map, and topographic map. 2 FOR AGENCY USE ONLY B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one). flat , Ilin , hilly, steep slopes, mountainous. The property is generally rectangular in shape and takes primary access from NE 20 Street. The site is currently developed with a single-family residence. The property slopes to the west at approximately 6% and is covered in grass, trees and other landscaping features associated with the existing residence. A man-made pond and regulated stream are located in the southwest comer of the site. Please refer to the preliminary plat map and submitted engineering drawings for contour information. b. What is the steepest slope on the site (approximate percent slope)? According to the field topographic survey, the steepest slope on the site is approximately 6% +-located along the southwest side of the project site. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, and muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the US Soil Conservation Service Soil Map, the site is primarily Indianola loamy fine sand, (InC) d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. According to the King County Sensitive Areas Map and various site visits, there are no indications of unstable soils. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Grading of the site will be necessary to modify the site for stormwater drainage flow. The exact quantity of grading is not known at this time, however, it is anticipated that the grading activities would be designed to balance and not require import or export of soil. Please refer to the preliminary grading plan for exact figures. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Some erosion could occur on -site as a result of construction activities; however, temporary erosion and sedimentation control measures to be approved by the City of Renton will be employed to reduce erosion impacts. All construction during the wet season will comply with the adopted Surface Water Design Manual and Appendix D concerning site coverage techniques. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? 3 FOR AGENCY USE ONLY 2. Air Due to the preliminary nature of the plans, the exact percentage of impervious surface associated with this project is currently unknown. The subject proposal will not exceed the maximum impervious surface area of 35% per lot imposed by City Code. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: During construction, the contractor will follow an approved temporary erosion and sedimentation control plan meeting City of Renton standards. Typical measures, which may be employed, include the use of silt fences, straw bales, and temporary storm drainage features. Hydroseeding exposed soils and cleared areas after construction will also reduce the potential for erosion. All construction during the wet season will comply with the adopted Surface Water Design Manual and Appendix D concerning site coverage techniques a. What types of emissions to the air would result from the proposal (.e., dust, automobile, odors, and industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Construction: Emissions and dust particulates generated primarily by construction equipment will be produced during the construction phase of this project The amount of emissions to the air will be minimal and will occur during the actual construction of the development. Lonq Tenn Air Quality: Long-term air impacts would be those typically associated with residential land uses. Sources of long-term emissions and odor could include vehicle emissions from increased vehicle use generated by the new residential units and emissions from wood burning fireplaces (if permitted). The additional vehicular emissions in these areas are not anticipated to concentrate and therefore are not anticipated to create a health hazard to the residents or surrounding areas. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: if particulates become suspended during construction, frequent watering of the site during the construction phase of the project would be used to help control dust and other particulates generated on the site. This will be accomplished in accord with the adopted Surface Water Design Manual and Appendix D concerning site coverage techniques. n FOR AGENCY USE ONLY 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, and wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. According to the King County Sensitive Areas Folio, there are no recorded streams or other water bodies on the subject site. The site is not within any 100 year flood plain. However, inspection of the site indicates that there is a regulated water course that crosses the southwest comer of the property and exits the site under Jones Ave. NE. A manmade pond has also been identified in the southwest comer of the property. Initial review of the site by Watershed Dynamics and the City has determined that the stream is a regulated feature and the man-made pond is not. The required stream buffer is 25' from the ordinary high water mark of the stream. The on -site stream appears to be a tributary to May Creek. Please see the attached Sensitive Area report by Watershed Dynamics. 2) Will the project require any work over, in or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. YES The existing man-made pond will be integrated into the proposed storm water facility in the southwest comer of the site. The existing stream channel location will be clarified and enhances. The existing channel is indistinguishable from the man-made pond. The applicant is also seeking a variance from the stream buffer regulations to allow for construction of the required frontage improvements on Jones Ave. NE. The proposed improvements will all take place within the existing right-of-way. A copy of the variance request and the preliminary frontage improvement plan has been included with the preliminary plat application packet. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No fill will be placed into the existing stream. The current proposal is to create the east bank of the stream channel, where there is none now. The man-made pond is unregulated. Please see the attached sensitive area report by Watershed Dynamics. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. Creation of the east bank of the stream may require a temporary diversion or restriction of the water flow during construction. A specific construction and mitigation plan will be developed as part of the engineering plan submittal for review and approval by the City of Renton. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan FOR AGENCY USE ONLY According to the King County Sensitive Areas Maps, no portion of the site lies within the 100-foot floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, agricultural; etc.) Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve.

BACKGROUND ERC MEETING DATE March 16, 2004 Project Name: Bartell Short Plat Owner/Applicant: Bob and Alina Bartell 1725 NE 24`h Street Renton, WA 98055 File Number: LUA-04-007, ECF, SHPL-H, V-H Project Manager: Kristina Catlin Project Description: The applicant is requesting Environmental (SEPA) Review, Hearing Examiner Short Plat approval, and Hearing Examiner Variance approval for a 9-lot subdivision of a 75,024 square foot (1.72 acre) site located within the Residential - 8 (R-8) zoning designation. An approximately 3,140 square foot single-family residence currently exists on the parcel, and is proposed to remain on Lot 7. The nine proposed lots range in size from 5,090 square feet to 13,743 square feet and are intended for the future development of detached single-family homes. Access is proposed via a new private street that would extend east from Jones Avenue NE and a driveway that would extend south from NE 24th Street along the eastern property boundary. Several of the proposed lots would have direct frontage on either Jones Avenue NE or NE 24th Street. Approximately 10,700 square feet of the site is proposed to be located in a storm tract. The storm tract would include the man-made pond existing on the site as well as the stream located in the southwest corner of the site. The required street improvements for the proposed plat would be located within the required 25-foot buffer and, therefore, a variance from the Land Clearing and Tree Cutting regulations is also required. Project Location: 1725 NE 241h Street Site Area: 1.72 acres (gross area) Existing Building Area: 3,140 square feet RECOMMENDATION: Staff recommends that the Environmental Review Committee Issue a Determination of Non -Significance — Mitigated (DNS-M).

The applicant shall install and maintain Temporary Erosion Control in accordance with the Department of Ecology Standards and to the satisfaction of the Development Services Division. 2. The applicant shall comply with the recommendations contained in the Stream Restoration Plan from Watershed Dynamics dated February 1, 2003, to the satisfaction of the Development Services Division. 3. The applicant shall install a grate on the exit culvert prior to recording of the short plat. 4. The applicant shall vegetate the stream and detention facility buffer areas with native vegetation, to the satisfaction of the Development Services Division prior to short plat recording. D. ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1. Earth Impacts: The subject site is rectangular in shape and relatively flat. The steepest slope on the site is approximately 6- percent along the southwest side of the property. According to the US Soil conservation Service Soil Map, the site is primarily Indianola loamy fine sand (InC). The site is predominantly vegetated with grass, trees, and landscaping associated with the existing residence. The existing trees on site include fruit trees (cherry, apple, pear), deciduous trees (maple, aspen, poplar, dogwood, willow), and coniferous (cedar, fir, pine). The trees range in size from 8-inches to 36-inches in diameter. The tree cutting and land -clearing plan submitted by the applicant identifies approximately 40 trees to be removed as part of the proposed subdivision. The majority of the trees to be removed are fruit trees associated with the existing residential use. The applicant indicated in the project overview that care would be taken to preserve the existing large trees along the stream and along the south property line. Some grading is proposed as part of the subdivision process in order to create a detention system and complete the proposed stream restoration activities. The exact quantity of grading is not known at this time, however, the applicant anticipates that the grading and filling activities on site will balance and not require the import or export of soil. Some erosion could occur on site as a result of construction activities. In order to mitigate the potential erosion impacts on the site and surrounding area, staff recommends that the applicant be required to install and maintain Temporary Erosion Control in accordance with the Department of Ecology Standards and to the satisfaction of the Development Services Division. Mitigation Measures: ■ The applicant shall install and maintain Temporary Erosion Control in accordance with the Department of Ecology Standards and to the satisfaction of the Development Services Division.

Surface Water Impacts: Several surface water features exist on and around the sub�iect property. The subject property (Bartell site) is bordered by roadside ditches that convey water both along NE 24t Street and along Jones Avenue NE. There is an existing stream channel in the southwest corner of the Bartell site and a human -made pond. In addition to the surface water on the Bartell site, the aforementioned stream flows across the property immediately upstream (south) of the Bartell site. The property immediately south also contains a human -made pond. Due to the presence of a stream and a manmade pond on the subject property, a field reconnaissance and stream restoration report was required as part of the short plat application. Larry D. Burnstad, Senior Biologist at Watershed Dynamics, completed the reconnaissance and report. The scope of the stream evaluation included investigation of the human -created pond and stream channel located in the southwest corner of the subject property, review of the outlet of the pond located on the east side of Jones Avenue NE, the culvert under Jones Avenue, and the open channel on the property west of the Bartell site. The channel conditions upstream (south) of the subject property and the pond located on the property immediately south of the Bartell site were also reviewed. The human -created pond on the Bartell property is somewhat trapezoidal in shape and is approximately 40 feet wide and 50 feet long at the widest and longest dimensions. The area around the pond includes a variety of both native and non-native vegetation. Although the plan community surrounding the pond was indicative of wetland characteristics, a soil evaluation revealed no hydric soils in the area around the pond. Based on the findings outlined in the report by Larry D. Burnstad dated August 4, 2003 and Renton Municipal Code Section 4-3-050, the human - created pond feature is not regulated by the City's wetland regulations. The water flowing out of the pond flows into a ditch along the east edge of Jones Avenue NE and into an 18-inch culvert that directs stream flow under Jones Avenue NE and into the open channel on the west side of the road. The stream flowing through the southwest corner of the Bartell property is subject to a 25-foot buffer requirement. RMC 4- 4-130D restricts land clearing and tree cutting within required stream buffer areas. The street improvements that will be required as part of the proposed project will be located within the required buffer area. Therefore, a variance from the tree cutting and land clearing regulations (RMC Section 4-4-030) will be required in order to develop the site as proposed. The applicant is proposing to perform several stream restoration activities on the site as part of this development. According to a report prepared by Larry D. Burnstad on February 1, 2003, "The objective of the stream restoration project is to re-establish a defined stream channel in the area where a human -made pond essentially obliterated the defined stream channel." Since the required street improvement may result in a grade increase for the existing stream, which will in turn raise velocities and increase the mobilization of silts, sands, and small gravel, the stream restoration plan proposes installing rock weirs at specific points along the stream channel in order to reduce the mobility of streambed material and allow for the formation of small pools. The structures would help to maintain grade control and reduce or avoid the risk of increased channel scour from increased velocities. Since there is not a source of stream bank gravel recruitment upstream of the site, the report recommends installing streambed gravel meeting specific specification along the streambed and stream bank. The installation of this material will contribute streambed gravel to the channel and further reduce the impacts of scour and degradation of the stream over time. In addition to the above recommendations, the stream restoration report also outlines specific recommendations for stream bank construction, large woody debris placement, and buffer planting. Staff recommends that the applicant be required to comply with the recommendations contained in the Stream Restoration Plan from Watershed Dynamics dated February 1, 2003, to the satisfaction of the Development Services Division. Correspondence was received from the property owners directly upstream of the proposed development regarding concerns about off -site drainage impacts upstream. Their letter mentioned past flooding of their property as a result of blockages at the exit culvert and concerns about the appearance of the proposed detention facility. In order to ensure that the existing flooding issues in the vicinity are not exacerbated by the proposed development, staff recommends that the applicant be required to install a grate on the downstream culvert to mitigate any future blockage problems. In addition, staff recommends that the applicant be required to vegetate the stream and detention facility buffer areas with native vegetation, to the satisfaction of the Development Services Division. Mitigation Measures: • The applicant shall comply with the recommendations contained in the Stream Restoration Plan from Watershed Dynamics dated February 1, 2003, to the satisfaction of the Development Services Division. • The applicant shall install a grate on the exit culvert prior to recording of the short plat. erc report.doc City of Renton P/B/PW Department Enviror itat Review Committee Staff Report BARTELL SHORT PLAT LUA-04-007, ECF, SHPL-H, V-H REPORT OF MARCH 16, 2004 Page 4 of 6 • The applicant shall vegetate the stream and detention facility buffer areas with native vegetation, to the satisfaction of the Development Services Division prior to short plat recording. Policy Nexus: SEPA Environmental Regulations, Renton Municipal Code, Tree Cutting and Land Clearing 3. Access/Transportation Impacts: Access to the proposed lots is proposed through a series of private access easements and direct street frontage. Lots 1, 2, and 3 have direct street frontage on Jones Avenue NE. Lots 1 and 2 are proposed to have individual driveway access to Jones Avenue NE. Lot 3 is proposed to take access from a private street serving Lots 4, 5, and 6. The private street will be required to have a 26-foot wide easement with a minimum of 20-feet of pavement. Due to the length of the private street, a hammerhead turnaround meeting Fire Department standards is also required. The proposed hammerhead turnaround is accommodated in an easement on Lot 7. Lots 8 and 9 have street frontage on NE 24th Street and are proposed to have individual driveway access directly to NE 24`h Street. A private driveway easement is proposed across Lot 9 for the benefit of the existing residence proposed to remain on Lot 7. The private driveway easement is 20-feet wide, which meets the standards for a shared driveway. A minimum of 12 feet of pavement will be required. Although the applicant has proposed an individual driveway for Lot 9, staff will likely recommend as a condition of short plat approval that Lot 9 be required to take access from the private driveway easement. Requiring Lot 9 to take access from a driveway easement shared with Lot 7 would reduce the number of driveway entrances to NE 241h Street and maintain compliance with the minimum separation distance for residential driveways required by the Renton Municipal Code. Mitigation Measures: No mitigation measures are recommended Policy Nexus: Not applicable. E.

DEPARTMENT ANALYSIS: PROJECT DESCRIPTION/BACKGROUND The applicant has proposed to subdivide a 1.72 acres (75,024 square foot) site located within the Residential — 8 dwelling units per acre (R-8) zone. The proposal would create 9 lots, intended for the future development of detached single-family residences. The existing residence is proposed to remain on Lot 7. The proposal for 9 single-family lots would arrive at a density of 5.66 dwelling units per acre. The nine proposed lots range in size from 5,090 square feet to 13,743 square feet. Access for the nine lots is proposed through a combination of direct street frontage, a private street, and a shared driveway easement. There is an existing stream channel in the southwest corner of the site and a human -made pond. A storm drainage tract is proposed in the southwest corner of the property, where the pond and stream currently exist. The applicant is proposing to perform several stream restoration activities on the site as part of this development in order to re-establish a defined stream channel in the area where it was obliterated by the construction of a human -made pond. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21 C, 1971 as amended), on March 16, 2004, the Environmental Review Committee issued a Determination of Non -Significance — Mitigated (DNS-M) for the project. The DNS-M included 4 mitigation measures. A 14-day appeal period commenced on March 22, 2004 and ended on April 5, 2004. No appeals of the threshold determination were filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES Based on an analysis of probable impacts from the proposal, the Environmental Review Committee (ERC) issued the following mitigation measures with the Determination of Non - Significance — Mitigated: 1. The applicant shall install and maintain Temporary Erosion Control in accordance with the Department of Ecology Standards and to the satisfaction of the Development Services Division. 2. The applicant shall comply with the recommendations contained in the Stream Restoration Plan from Watershed Dynamics dated February 1, 2003, to the satisfaction of the Development Services Division. 3. The applicant shall install a grate on the exit culvert prior to recording of the short plat. 4. The applicant shall vegetate the stream and detention facility buffer areas with native vegetation, to the satisfaction of the Development Services Division prior to short plat recording. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address issues from the proposed development. These comments are contained in the official file and the essence of the comments has been incorporated into the appropriate sections of this report. hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE., April 13, 2004 Page 4 of 11 5. CONSISTENCY WITH SHORT PLAT CRITERIA: Approval of a short plat is based upon several factors. The following short plat criteria have been established to assist decision makers in the review of the subdivision: (a) Compliance with the Comprehensive Plan Designation. The subject site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. The objective of the RSF designation is to protect and enhance single-family areas, encourage quality neighborhoods, improve opportunities for better public transportation and make more efficient use of urban services and infrastructure. The proposal is consistent with the objective of the RSF designation because it would provide for the future construction of eight new single-family homes and would promote goals of infill development. The proposed plat is consistent with the following Comprehensive Plan policies: Policy LU-34. Net development densities should fall within a range of 5 to 8 dwelling units per acre in Residential single Family neighborhoods. - The proposed density of the short plat is 5.66 dwelling units per acre, which is within the allowed density range of the R-8 zone. Policy LU-35. A minimum lot size of 4,500 square feet should be allowed in single-family residential neighborhoods except when flexible development standards are used for project review. - Each of the proposed lots exceeds 4,500 square feet. Policy H-4. Encourage infill development as a means to increase capacity. - The proposed project would create lots for eight new single-family homes on a parcel that currently contains only one single-family home, thereby achieving the infill of a currently underutilized property. (b) Compliance with the Underlying Zoning Designation. The 1.72-acre site is designated Residential — 8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of up to eight new dwelling units and associated improvements. Density — The allowed density range in the R-8 zone is a minimum of 5.0 to a maximum of 8.0 dwelling units per acre (du/ac) for lots exceeding one-half acre in size. Net density is calculated after critical areas, public rights -of -way, and portions of private roadways serving three or more units are deducted from the gross acreage of the site. After the deduction of the private roadway serving three or more units (5,429 square feet) from the 75,024 gross square foot site (75,024 gross square feet — 5,429 total deducted area = 69,595 net square feet or 1.59 net acre), the proposal would arrive at a net density of 5.66 dwelling units per acre (9 units / 1.59 acre = 5.66 du/ac), which is within the density range allowed in the R-8 zone. Lot Dimensions — The minimum lot size permitted in the R-8 zone is 4,500 square feet. A minimum lot width of 50 feet and a minimum lot depth of 65 feet are required for interior lots. Lots 2 through 9 would be considered interior lots. Corner lots are required to have a minimum lot width of 50 feet and a minimum lot depth of 65 feet. Lot 1 would be considered a corner lot. The! nine lots on the subject site are proposed at the following lot sizes and dimensions (rounded to the nearest whole number): Lot Size Width Depth Lot 1 6,021 square feet 60 feet 102 feet Lot 2 5,536 square feet 54 feet 103 feet Lot 3 6,905 square feet 66 feet 103 feet Lot 4 6,483 square feet 20 / 73 feet 114 feet Lot 5 7,366 square feet 15 / 88 feet 133 feet Lot 6 6,515 square feet 0 / 113 feet 114 feet Lot 7 13,743 square feet 152 feet 90 feet hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE. April 13, 2004 Page 5 of 11 Lots 4, 5, and 6 are irregular shaped lots that do not meet the minimum width requirement on one or more property lines. Renton Municipal Code Section 4-7-170.F allows pipestem lots for new plats to achieve densities permitted within the zoning code. Lot 4 would be considered a pipestem lot. Lots 5 and 6 do not meet the minimum pipestem width requirement of 20 feet. However, the lots could be modified to meet standards. Staff recommends as a condition of short plat approval that the lot boundaries of Lot 5 and Lot 6 be altered to qualify as pipestem lots so that the proposed density of this plat may be maintained. Setbacks — The R-8 zone requires front and rear yard setbacks of 20 feet, side yard along street setbacks of 15 feet, and interior side yard setbacks of 5 feet. For lots with street frontage, the front yard is the yard separating the structure from the public right-of-way. This applies to Lots 2, 3, 8, and 9. Lot 1 is a corner lot with frontage on two public streets. As proposed, Lot 1 is using the west property line along Jones Avenue NE as the front property line. Lot 7 is an interior lot that has elected to use the north property line as the front property line. The existing house will continue to comply with the required setbacks. Lots 4 through 6 would qualify as pipestem lots once the recommended alterations are made to Lots 5 and 6. Renton Municipal Code Section 4- 7-170.F.1 states that portions of the lot narrower than 80-percent of the minimum permitted width shall not be used for measurement of setbacks. Therefore, the front setbacks for Lots 4 through 6 will be measured from the point at which the lot width is at least 40 feet. The plat plan includes setback lines for each lot showing potential building envelopes. Building Standards — The R-8 zone permits one single-family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet in size. Building height in the R-8 zone is limited to 2 stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is limited to 35% of the lot area or 2,500 square feet, whichever is greater, for lots over 5,000 square feet in size. The footprint of the existing residence would result in approximately 18-percent lot coverage, which is less than the maximum lot coverage allowed in the zone. Compliance with building standards will be verified prior to the issuance of building permits for proposed structures on the eight new lots. Parkin — Each detached dwelling unit is required to provide two off-street parking stalls per unit. Tandem parking is permitted. The proposed building pads appear to be adequately sized to provide required parking. No parking will be permitted within the proposed private street, since the street is required as emergency access to the proposed lots. Staff recommends as a condition of short plat approval that the proposed private street be posted with "No Parking — Fire Lane" signs prior to recording of the short plat in order to prevent guests and residents from blocking emergency access to neighboring properties. (c) Compliance with Subdivision Regulations. Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement or street per the requirements of the Street Improvement Ordinance. The lot lines of the proposed lots fronting Jones Avenue NE and NE 241h Street (Lot 1, 2, 3, 8, and 9) are at right angles to street lines. The proposed private street extending east from Jones Avenue NE would provide access to Lots 3 through 6. Since Lot 3 has street frontage and access to the private street, staff recommends as a condition of approval that a note be place on the face of the short plat requiring Lot 3 to take access from the private street- This condition would eliminate any potential driveway separation distance issues on Lot 3 and reduce the total number of access points along Jones Avenue NE. Due to concerns from the neighboring property to the east of the project site, and in an effort to prevent driveway separation distance issues and reduce the number of private entrances onto NE 24`h Street, staff recommends as a condition of short plat approval that a note be placed on the face of the short plat requiring Lot 9 to access from the shared driveway easement extending south from NE 24th Street to Lot 7. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE: April 13, 2004 Page 6 of 11 Each of the proposed lots satisfies the minimum lot area requirements of the R-8 zone. Lots 5 and 6 need to be altered to meet the minimum dimensions required for pipestem lots. Staff has recommended as a condition of short plat approval that the lot boundaries of Lot 5 and Lot 6 be altered to comply with the minimum pipestem width of 20 feet. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of suitable detached single-family homes. Property Corners at Intersections: All lot corners at intersections of dedicated public rights -of -way, except alleys, shall have minimum radius of 15 feet. Lot 1 of the proposed subdivision would be located at the intersection of NE 241' Street and Jones Avenue NE. The owner will be required to dedicate a 15-foot turning radius at the corner as right- of-way prior to short plat recording. (d) Reasonableness of Proposed Boundaries Access and Street Improvements: Assuming approval of staff recommendations to limit access for Lots 3 and 9, Lots 1, 2, and 8 would be the only lots with direct driveway access to public right-of-way. Lots 3 through 6 would take access from the private street extending east from Jones Avenue NE. The private street would have a 26-foot wide easement with a minimum pavement width of 20 feet. A hammerhead turnaround would be provided on Lot 7 for emergency vehicle access. Lot 7 and Lot 9 would take access from a shared driveway easement extending south from NE 241h Street along the east property line of the site. The shared driveway easement would be 20 feet in width with a minimum pavement width of 12 feet. Due to concerns raised from the neighbors to the east over the proximity of the shared driveway to the east property line, staff recommends that the applicant be required to install a 6-foot solid fence along the length of the shared driveway easement prior to recording of the short plat. As part of the proposed development, the applicant will be required to install full street improvements along NE 241h Street and Jones Avenue NE. Installation of street improvements is required prior to recording of the short plat. The required street improvement would encroach into the 25-foot required stream buffer for the stream in the southwest corner of the site. In order to install the required street improvements, the applicant must have an approved variance from Renton Municipal Code (RMC) Section 4-4-130D, which prohibits land clearing within 25 feet of the ordinary high water mark of creeks or streams. The variance request is evaluated in the "Compliance With Variance Criteria" section of this report. The proposed subdivision is expected to generate additional traffic on the City's street system. To mitigate the impacts to the local street system, staff recommends as a condition of short plat approval that the applicant be required to pay a Traffic Mitigation Fee of $75.00 per additional generated trip prior to recording, with credit give for the existing residence. Each new single- family lot is expected to contribute 9.57 additional trips. The proposed short plat is expected to add approximately 76.56 new traffic trips to the City's street system. For the proposal, the Traffic Mitigation Fee is estimated at $5,742.00 (8 new lots x 9.57 trips x $75 per trip = $5,742.00). Topography: The subject site is rectangular in shape and relatively flat. The steepest slope on the site is approximately 6-percent. According to the US Soil conservation Service Soil Map, the soils on site are primarily Indianola loamy fine sand (InC). The site is predominantly vegetated with grass, trees, and landscaping associated with the existing residence. The existing trees on site include fruit trees (cherry, apple, pear), deciduous trees (maple, aspen, poplar, dogwood, willow), and conifers (cedar, fir, pine). The trees range in size from 8-inches to 36-inches in diameter. The tree cutting and land -clearing plan submitted by the applicant identifies approximately 40 trees to be removed as part of the proposed subdivision. The majority of the trees to be removed are fruit trees. The applicant indicated in the project overview that care would be taken to preserve the existing large trees along the stream and the southern property line. Some grading is proposed as part of the subdivision process in order to create a detention system and complete the proposed stream restoration activities. The exact quantity of grading is not known at this time, however, the applicant anticipates that the grading and filling activities on site will balance and not require the import or export of soil. hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE. April 13, 2004 Page 7 of 11 In order to mitigate the potential erosion impacts on the site and surrounding area, the Environmental Review Committee placed a mitigation measure on the project that required the applicant to install and maintain Temporary Erosion Control in accordance with the Department of Ecology Standards and to the satisfaction of the Development Services Division. Relationship to Existing Uses: The subject site is currently developed with a single-family residence. Several nearby properties have recently developed or are currently being evaluated for development proposals. The proposed lots are compatible with other newly created and proposed lots in this area. The proposal is consistent with the intent of the both the Comprehensive Plan and Zoning Code and would not be out of character with recent development in the area. (e) Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide Code required improvements, and mitigation fees. Staff recommends as a condition of short plat approval that the applicant be required to pay a Fire Mitigation Fee based on $488.00 per new single-family lot, with credit given for the existing residence. The fee is estimated at $3,904.00 ($488 x 8 = $3,904.00) and is payable prior to the recording of the short plat. In order to provide safe and efficient emergency access, fire department access roads are required to have a pavement width of at least 20 feet. Staff has recommended as a condition of short plat approval that the proposed private street be posted with "No Parking — Fire Lane" signs in order to prevent guests and residents from blocking emergency access to neighboring properties. Recreation: The proposal does not provide on -site recreation areas for future residents of the proposed plat. It is anticipated that the proposed development would generate future residents that would utilize the City's parks, programs, and recreational facilities. Staff recommends as a condition of short plat approval that the applicant be required to pay a Parks Mitigation Fee based on $530.76 per each new single-family lot, with credit given for the existing single-family residence. The mitigation fee will be used to contribute toward future park and recreation facilities. The fee is estimated at $4,246.08 (8 x $530.76 = $4,246.08) and is payable prior to the recording of the short plat. Schools: The site is located within the boundaries of the Renton School District. Renton School District No. 403 has indicated that Kennydale Elementary School, McKnight Middle School and Hazen High School can accommodate the increased student enrollment that may result from the development of the proposed project, estimated at 3.52 students (8 new lots x 0.44 students = 3.52). Storm Water: Several surface water features exist on and around the subject property. The subject property is bordered by ditches that convey water along NE 24th Street and along Jones Avenue NE. There is an existing stream channel in the southwest corner of the site and a human -created pond. Due to the presence of a stream and a manmade pond on the subject property, a field reconnaissance and stream restoration report was required as part of the short plat application. Larry D. Burnstad, Senior Biologist at Watershed Dynamics, completed the reconnaissance and report. The human -created pond on the Bartell property is trapezoidal in shape and is approximately 40 feet wide and 50 feet long at the widest and longest dimensions. The area around the pond includes a variety of native and non-native vegetation. Based on the findings outlined in the report by Larry D. Burnstad dated August 4, 2003, the human -created pond feature is not regulated by the City's critical area regulations. It is, however, subject to a 25-foot buffer under the Tree Cutting and Land Clearing regulations. The street improvements that will be required as part of the proposed short plat will be located within the required buffer area. Therefore, a variance from the tree cutting and land clearing regulations (RMC Section 4-4-030) will be required to develop the site as proposed. hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE: April 13, 2004 Page 8 of 11 The water flowing out of the pond flows into a ditch along the east edge of Jones Avenue NE and into an 18-inch culvert that directs stream flow under Jones Avenue NE and into the open channel on the west side of the road. The applicant is proposing to perform several stream restoration activities on the site as part of this development. According to a report prepared by Larry D. Burnstad on February 1, 2003, 'The objective of the stream restoration project is to re- establish a defined stream channel in the area where a human -made pond essentially obliterated the defined stream channel." Since the required street improvements may result in a grade increase for the existing stream, the stream restoration plan proposes installing rock weirs at specific points along the stream channel in order to reduce the mobility of streambed material, allow for the formation of small pools, maintain grade control, and reduce the risk of channel scour. Since there is not a source of stream bank gravel recruitment upstream of the site, the report recommends installing streambed gravel along the streambed and stream bank to reduce the impacts of scour and degradation of the stream over time. In addition to the above, the stream restoration report also outlines specific recommendations for stream bank construction, large woody debris placement, and buffer planting. The Environmental Review Committee imposed a mitigation measure that the applicant be required to comply with the recommendations contained in the Stream Restoration Plan from Watershed Dynamics dated February 1, 2003. Correspondence was received from the property owners directly upstream of the proposed development regarding concerns about off -site drainage impacts upstream. Their letter mentioned past flooding of their property as a result of blockages at the exit culvert and concerns about the appearance of the proposed detention facility. In order to ensure that the existing flooding issues in the vicinity are not exacerbated by the proposed development, the Environmental Review Committee recommended that the applicant be required to install a grate on the downstream culvert to mitigate any future blockage problems. In addition, the Environmental Review Committee recommended that the applicant be required to vegetate the stream and detention facility buffer areas with native vegetation, to the satisfaction of the Development Services Division. The site drains to the South Kennydale Creek basin, sub -basin of Lake Washington. No significant downstream drainage problems have been identified. A drainage analysis and design meeting the 1990 King County Surface Water design manual is required for the project. The preliminary design submitted with the application shows a 12-inch pipe connection to the downstream system. Verification that the pipe systems being installed have enough capacity for the future build -out conditions of the basin will be required with the utility engineering plan application for this project. A Surface Water System Development Charge, based on $715.00 per new single-family lot, will be required prior to the issuance of construction permits for the short plat. Water and Sanitary Sewer Utilities. There is an existing 8-inch and 12-inch water main fronting the property. A new 4-inch water main will be required to serve the internal lots with domestic water. The site is located within Aquifer Protection Zone 2 and a water pressure zone of 435. Water System Development Charges, based on $1,525.00 per new single family lot, will be required prior to the issuance of construction permits. There is an 8-inch sewer main along the frontage of the site. The project falls within two Sewer Assessment Districts (Jones Avenue SAD #8402 and West Kennydale SAD #9204). A Sewer Assessment District fee in the amount of $585.00 per unit is due for the Jones Avenue SAD and $10,473.86+interest is due for the West Kennydale SAD. Wastewater System Development Charges of $900.00 per new single family lot will also be required prior to the issuance of construction permits for the short plat. 6. CONSISTENCY WITH VARIANCE CRITERIA: City of Renton Development Regulations Section 4-9-250.B.5. — The Reviewing Official shall have authority to grant a variance upon making a determination, in writing, that the conditions specified below have been found to exist: hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE., April 13, 2004 Page 9 of 11 (a) That the applicant suffers undue hardship and the variance is necessary because of special circumstances applicable to subject property, including size, shape, topography, location or surroundings of the subject property, and the strict application of the Zoning Code is found to deprive subject property owner of rights and privileges enjoyed by other property owners in the vicinity and under identical zone classification. A variance from the Tree Cutting and Land Clearing regulations (RMC Section 4-4-030) is necessary due to the presence of a stream in the southwest corner of the property. The existing stream runs parallel to Jones Avenue NE, which is also within the stream buffer. RMC Section 4- 4-030 requires a 25-foot buffer from the Ordinary High Water Mark (OHWM) of the stream. Without a variance, the applicant is unable to install the required street improvements associated with the proposed short plat. Many other property owners in the area and under the same zoning classification have recently subdivided their properties. To deny the requested variance from the required 25-foot stream buffer would be to deprive the owner of the subject site the ability to subdivide that many other owners in the vicinity enjoy. (b) That the granting of the variance will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and zone in which subject property is situated. Allowing a variance from the required 25-foot stream buffer is not anticipated to be detrimental or injurious to the public welfare or neighboring properties. The applicant has proposed several stream restoration measures that will help to return the stream to a more natural condition and undo some of the human alteration to the natural stream channel. Several restoration activities are proposed to mitigate any increased stream gradient associated with the street improvements (see discussion in the "Storm Water" portion of this report for more information). In addition to the mitigation and restoration activities proposed to enhance the existing stream, allowing street frontage improvements will enhance the safety and efficiency of vehicular and pedestrian traffic along Jones Avenue NE. (c) That approval shall not constitute a grant of special privilege inconsistent with the limitation upon uses of other properties in the vicinity and zone in which the subject property is situated. The approval of the requested variance would not constitute a grant of special privilege inconsistent with the limitation upon the uses of other properties in the vicinity. Many of the other properties in the vicinity have subdivided and installed street frontage improvements. The granting of the requested variance would allow the applicant to install frontage improvements that would comply with Renton Municipal Code standards for streets. Without a variance from the tree cutting and land clearing regulations, the applicant would need relief from the regulations requiring street improvements for new short plats. (d) That the approval as determined by the Reviewing Official is a minimum variance that will accomplish the desired purpose. Jones Avenue NE is located within the required 25-foot stream buffer. Any improvements to Jones Avenue NE would, therefore, also be located within the stream buffer. The applicant is proposing to do only the minimum amount of improvements required by code. Therefore the variance to allow the installation of street improvements within the required 25-foot stream buffer is the minimum variance needed to accomplish compliance with the City of Renton subdivision regulations. hex report.doc City of Renton P/B/PW Department Report to the Hearing Examiner Bartell Short Plat LUA-04-007, SHPL-H, V,H, ECF PUBLIC HEARING DATE: April 13, 2004 Page 10 of 11 G.

SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on April 6, 2004. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area; the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the April 13, 2004 hearing. The legal record is recorded on CD. The hearing opened on Tuesday, April 13, 2004, at 9:04 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original application, reports, staff comments, and other material pertinent to the review of the project Exhibit No. 2: Zoning Map Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-H, ECF May 4, 2004 Page 2 Exhibit No. 3: Short Plat Plan Exhibit No. 4: Utility Plan Exhibit No. 5: Tree Cutting/Land Clearing Plan Exhibit No. 6: Revised Short Plat Plan Exhibit No. 7: Copy of Existing Pond and Proposed Future Stream Restoration The hearing opened with a presentation of the staff report by Kristina Catlin, Planner, Development Services, City of Renton, 1055 S Grady Way, Renton, Washington 98055. The parcel is approximately 1.72 acres, there is an existing stream channel in the southwest corner of the site and a human -made pond connected to that. The applicant is proposing several stream restoration activities on the site that.will rework this area. This project went before the Environmental Review Committee, a Determination of Non -Significance - Mitigated with four mitigation measures was issued. No appeals were filed. The subject site is designated Residential Single Family (RSF), the proposal is consistent with this designation. The proposed density of the short plat is 5.66 dwelling units per acre, which is within the allowed density range of the R-8 zone. The stream buffer was not deducted in the calculation because the stream is not classified as a critical area. Most of the proposed lots exceed 4,500 square feet which meets the required minimum dimensions for the R-8 zone. Lots 4, 5 and 6 do not meet the minimum width requirement. They are classified as a pipestem lot, which has a minimum pipestem width of 20 feet. Lots 5 and 6 do not meet that requirement, Lot 5 at the narrowest portion is just over 15 feet and Lot 6 is a triangular shaped lot and the point is considered to have a 0 lot width. The lot lines between Lot 5 and Lot 6 can be adjusted so that they can be considered pipestem lots. All setbacks, with the adjustment to Lots 4, 5, and 6, meet the requirements for the R-8 zone. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet. Compliance with the building standards will be verified prior to the issuance of building permits for proposed structures on the eight new lots. No parking will be permitted within the proposed private street, since the street is required as emergency access to the proposed lots. The proposed private street will be posted with "No Parking — Fire Lane" signs. Staff recommends that Lot 3 be required to take access from the private street. Also along NE 24'1' Street, Lot 9 has frontage on NE 24"' but also contains the easement that will serve Lot 7. Staff recommends that Lot 9 be required to access from this driveway easement. Each of the proposed lots satisfies the minimum lot area requirements of the R-8 zone. Lots 5 and 6 need to be altered to comply with the minimum lot width and depth. With approval of staff recommendations, Lots 1, 2, and 8 would be the only lots with direct driveway access to pubic right-of-way. Due to concerns raised from the neighbors to the east over the proximity of the shared driveway to the east property line, the applicant will be required to install a 6-foot solid fence along the length of the shared driveway easement prior to recording the short plat. Full street improvements along NE 24°i Street and Jones Avenue NE will be required. These improvements will encroach onto the required stream buffer, therefore, a land variance is being requested also. A Traffic Mitigation fee is required. The subject site is rectangular in shape and relatively flat. The site is predominantly vegetated with grass, trees and landscaping associated with the existing residence. Tile applicant intends to remove approximately 40 trees, Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-H, ECF May 4, 2004 Page 3 the majority of which are fruit trees. The applicant intends to take care to preserve the existing large trees along the stream and the southern property line. Police and Fire have indicated that sufficient resources exist to furnish services to the proposed development provided that a Fire Mitigation Fee be paid. A Park Mitigation Fee is required. The site is located within the boundaries of the Renton School District and they have indicated that they can accommodate the increased student enrollment. Several surface water features exist in and around the subject property. The human -created pond is not regulated by the City's Critical Area regulations, the stream is subject to a 25-foot buffer under the Tree Cutting and Land Clearing regulations. Tile street improvements will require a land variance. The objective of tile stream restoration project is to return the stream to some semblance of what it was before it was altered to be diverted into this pond. Correspondence was received from the owners directly upstream, south of the property, stating that there have been some past issues of flooding on the property that resulted from blockages in the culverts. They had concerns about the appearance of the proposed detention facility. The ERC recommended that the applicant install a grate on the culvert that goes under Jones Avenue NE in order to help some of the blockage problems. This site is located within an aquifer protection zone and a water system development charge per new single family lot will be required prior to issuance of the construction permits. The project falls within two sewer assessment districts, the Jones Avenue Sewer Assessment Sewer District and West Kennydale Sewer Assessment Sewer District. Sewer assessment fees are required for each of the Sewer Districts. With regard to the required variance, there are several criteria which must be evaluated for the variance. The variance that is needed is a variance from the 25 foot no touch buffer around a stream, in this case the buffer extends east onto the property and west onto Jones Avenue NE. Any alterations within that right-of-way will fall within that buffer. In this case a variance from the tree cutting and land clearing regulations is necessary because of the presence of the stream in the southwest corner of the property. The existing stream runs parallel to Jones Avenue NE, which is also within the stream buffer, and the requirement for a 25-foot buffer from the ordinary high mark of the stream, without this variance the applicant would be unable to install the street improvements that the City of Renton requires. The Examiner inquired as to what the hardship actually was. Ms. Catlin explained that there are two requirements available in this situation, and one requirement states that there must be a 25-foot stream buffer, and the other requirement states that there must be street improvements, and those two requirements cannot coexist together in this situation. The second criteria of granting the variance is that it would not be detrimental to public welfare. The third criteria is that the variance will not constitute a grant or special privilege inconsistent with other properties in the vicinity. This variance would allow this property to subdivide in a manner similar to other properties in the vicinity and install the required street frontage improvements. The Examiner further stated that the City had changed its ordinances in order to protect streams, and just because prior development encroached on what now is a required buffer, does that mean that we should continue to justify it? Ms. Catlin stated that looking at the site now, there is a stream buffer that has been obliterated, it has been totally diverted into a pond on the site. The activity proposed here brings that more into a standard stream channel, which is culverted under Jones and comes out on the west side. What will be seen is a better functioning and protected stream that what is presently on the property. The fourth criteria for the variance is that it's determined by the reviewing official to be the minimum variance needed to accomplish the desired purpose. In this case, it is to allow only the street frontage improvements. Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-14, ECF May 4, 2004 Page 4 Staff recommends approval of the Bartell Short Plat subject to conditions outlined in the Staff Report Hans Korve, DMP Engineering, 726 Auburn Way North, Auburn, WA 98002 stated that in working with Staff over the past few months, conclusions have been reached, Staff has done a great job with a tight site. The issues involving Lots 4, 5, and 6 were resolved with Staff prior to the hearing, twelve copies of the revised plan have been submitted. No modifications were made to the actual lots themselves, the modifications were made in the stems that extended into the driveway easement. The pipestems of each lot was squared off, particularly Lots 5 and 6. The driveway access for Lot 9 was eliminated so that it will take access off the shared driveway easement with the existing house on Lot 7. In regard to the variance, in the southwest corner of the site, the manmade pond currently exists. There is a series of trees up against Jones Avenue that form a natural berm between an existing storm water ditch on the west side against Jones Avenue and the stream channel on the east side. There currently is no distinguishing between the stream and the pond. There is no stream today, it simply enters the property and bursts out into a giant pond and then goes under Jones Avenue and becomes channelized again. The proposal is to recreate a channel, create a buffer, and then put the storm water pond in the current location of the manmade pond. Larry Burnstad, Watershed Dynamics, PO Box 215, Enumclaw, WA 98022 stated that the ordinary high water line is within four feet at the closest point and seven feet at the furthest point from the property line. Upstream is a concrete lined pond and is the control point for which the water enters the property site. The culvert will be extended to the east in order to accommodate the street improvements. This limits what can be done in restoring a meandering channel pattern. Several alternatives were looked at but none seemed as attainable as what has been proposed. Kayren Kittrick, Development Services stated that the dedication of the radius curve at the corner of Jones and 24th will be presented to Council as a separate condition. In regard to trees and right-of-way, since the code has changed and there are more beautiful trees existing on the right-of-way or on the edge of the right-of-way and there are some protection limits that are to be held for maintaining the tree if at all possible, staying outside of the crowns and root balls. There are some creative modifications in street standards in order to go around them, pushing the street and sidewalk over as far as possible in order to maintain as many of the trees as possible especially in a location like this where it is part of the stream buffer. It is only a 20-foot pavement, so there is some play area. If the trees are in the way of the utility, then it becomes more problematical. It appears that the way it currently stands, sidewalk and street improvement can be shifted to accommodate the trees. The Examiner inquired as to water runoff. Ms. Kittrick stated that it would have to be figured if infiltration is part of this. The Special Assessment District fees from Kennydale Sewer District are against the entire property, not per lot. Larry Burnstad, stated that in trying to retain the trees on the west side of the property line, one of the things talked about is being able to meander the sidewalk as opposed to a straight sidewalk and using vertical containment such as keystone block so that a small amount of damage is done to the roots on the west side of the tree, but maintain all the root.system to the north, south and east which should allow the tree to survive. They could trim the trees up so pedestrians may pass under the trees which would allow maximization of the saving of the trees. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at 10:32 a.m. FINDINGS, CONCLUSIONS & RECOMMENDATION Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-H, ECF May 4, 2004 Page 5 Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The applicants, Bob and Alina Bartell, filed a request for approval of a 9-lot Short Plat together with a variance from land clearing regulations adjacent to a stream. 2. The yellow file containing the staff report, the State Environmental Policy Act (SEPA) documentation and other pertinent materials was entered into the record as Exhibit #1. 3. The Environmental Review Committee (ERC), the City's responsible official, issued a Declaration of Non -Significance - Mitigated (DNS-M) for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is located on the southeast corner of NE 24th Street and Jones Avenue NE at 1725 NE 24th Street. Aberdeen Avenue NE is east of the subject site. 6. The subject site is approximately 1.72 acres or 75,024 square feet in area. The parcel is rectangular. The subject site is approximately 294.90 feet long (north to south) by approximately 254.77 feet wide. 7. The subject site is fairly level with a stream running across the southwest corner of the site immediately adjacent to Jones Avenue. A man-made pond is located east of the stream. 8. The subject site was annexed to the City with the adoption of Ordinance 1827 enacted in March 1960. 9. The subject site is currently zoned R-8 (Single Family - 8 dwelling units/acre). 10. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of single-family uses. 11. The subject site contains a home that would be retained on what would be Proposed Lot 7 located in the eastern portion of the site. 12. The applicant proposes dividing the subject site into 9 single-family lots. A storm tract will be located in the southeast corner of the parcel in the location where a pond was located. 13. The lots range in size from 5,000 square feet to approximately 13,743 square feet. 14. Proposed Lots 1, 2, 3, 7, 8 and 9 would be rectangular lots with access to either Jones or 24th Street. Proposed Lot 7, the location of the existing home would be accessed from an easement to 24th across Proposed Lot 9. 15. Proposed Lots 4, 5 and 6 would be interior lots served by an easement road across Proposed Lot 3 and hammerhead turnaround. The easement would run west to Jones Avenue. These three lots would be somewhat wedge shaped. 16. Staff recommended that to reduce the number of driveways on the existing streets and to limit driveways being too close together that Proposed Lot 9 use the easement for Proposed Lot 7 for access Bartell Short Plat File No.: LUA-04-007 SHPL-1-1, V-H, ECF May 4, 2004 Page 6 and Proposed Lot 3 use the easement for Proposed Lots 4, 5 and 6 for its access. In order to protect the lot east of the Proposed Lots 7 and 9 easement staff recommended that a fence be erected. 17. Proposed Lot 1 is required to dedicate property at the intersection of Jones and 24th in order to create an appropriate radius turn. 18. Proposed wedge-shaped Lots 5 and 6 narrow too much where they join the access easement and do not meet the regulations for pipestem width. Staff noted that the lots could be redesigned to meet code. The applicant agreed to alter the lots. 19. The development of 9 lots after the reduction of sensitive areas and roadways will result in a density of 5.66 units per acre. 20. The residential lot is covered with residential landscaping including grass, trees, shrubs and fruit trees as well as a variety of deciduous and conifers. Many of the trees would be removed to allow for the development of roads and building pads. The applicant would retain some trees along the western stream and some along the south property line. 21. Development of 9 single family homes will generate approximately 90 vehicle trips per day or 80 new trips giving credit for the one existing home. 22. The development would add approximately 3 or 4 new students to the school system. These students would be spread across the grades of the Renton School District 23. Storm water will be detained in the southwest corner of the subject site. It will be released to an in - street system. 24. The stream that runs through the site was widened to create a manmade pond. The pond, since it was manmade, is not subject to ordinary critical areas regulations but the vegetation within 25 feet of it can only be cleared with approval of a variance from the Tree Cutting and Land Clearing regulations. Street improvements along Jones would require some clearing and the applicant has applied for a variance. As part of its proposal to install the needed improvements along Jones Avenue the applicant proposed restoring the stream channel to a more natural state including banks and gradient. Rock weirs to establish a gradient, gravel for a more natural streambed, native plantings and other improvements outlined in the applicant's Stream Restoration Plan (February 1, 2004) will be installed. 25. There has been some flooding upstream of the subject site since the manmade pond has not functioned effectively at times causing water to backup onto nearby property. The proposed stream restoration plan along with ERC conditions and regulations required for storm water should address some of the problems. Staff reported that there were no downstream storm water problems. 26. The subject site is located in Aquifer Protection Zone 2. 27. The subject site will receive domestic water and sanitary sewer service from the City. CONCLUSIONS: Variance The Reviewing Official shall have authority to grant a variance upon making a determination in writing Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-1-1, ECF May 4, 2004 Page 7 that the conditions specified below have been found to exist: a. That the applicant suffers undue hardship and the variance is necessary because of special circumstances applicable to subject property, including size, shape, topography, location or surroundings of the subject property, and the strict application of the Zoning Code is found to deprive subject property owner of rights and privileges enjoyed by other property owners in the vicinity and under identical zone classification; b. That the granting of the variance will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and zone in which subject property is situated; C. That approval shall not constitute a grant of special privilege inconsistent with the limitation upon uses of other properties in the vicinity and zone in which the subject property is situated; d. That the approval as determined by the Reviewing Official is a minimum variance that will accomplish the desired purpose. It appears that the proposed variance is appropriate given the restoration effort which will provide a more natural stream channel and environment. The stream and its vegetation lie immediately adjacent to an existing street, Jones Avenue NE. It would be very difficult to install the necessary safety improvements including curbs, gutters, and pedestrian sidewalks along Jones if the variance were not approved. A combination of location and topography justify the variance in this case. The approval of the variance should not prove materially detrimental to the subject site, the general public or other property. The removal of the vegetation will allow safety improvements along Jones but the applicant will be repairing an impaired stream course, installing native vegetation and may prevent upstream problems by unclogging the stream's current failing outlet. 4. The applicant would need a variance from either the Tree Cutting regulations or the Street Improvement standards to develop the subject site. The approval of this variance will allow the restoration of a more natural stream channel. It will allow the installation of a consistent roadway profile in this area. The variance clearly involves tradeoffs but the stream is in anything but a natural state. Approval of the variance, as noted, will allow the repair of the natural systems and hopefully, rectify some other stream flow and storm water problems. It appears that it is the minimum necessary in this case. Plat 6. The proposed plat appears to serve the public use and interest. The plat creates additional single family lots in an area served by urban services, restores a more natural stream course and may solve some existing drainage problems. 7. The applicant has demonstrated the interior lots, Proposed Lots 4, 5 and 6, can be designed to meet City regulations, particularly those applicable to pipestem access. In addition, access to some exterior lots can be achieved from easement drives and roads rather than separate, independent driveways thereby eliminating additional intersections along both Jones and 24th Street. The recommendations of staff are appropriate to reduce the number of driveways. Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-H, ECF May 4, 2004 Page 8 Since the access for Proposed Lots 7 and 9 runs along a third party lot, that lot should be protected by a fence. 9. The plat will have an impact on the City's fire, roads and recreational systems. The City has adopted a set of fees that help offset the impacts of development on those public services and those standard fees appear reasonable to offset those impacts. 10. The development of new homes will bring new residents and new noise to the area as well as the impacts on roads and park. The impacts of new populations are not unusual for a single-family community. 11. The development of the subject site will increase the tax base of the City. 12. The proposed density of 5.66 dwelling units per acre meets the Zoning Code and Comprehensive Plan. 13. The applicant shall have to create a maintenance agreement for the detention facilities and the private easement roadways. 14.. In order to create a smooth intersection radius for Jones and 24th, the applicant shall have to dedicate property subject to review and approval of the City. 15. In conclusion, the proposed plat and variance appear to allow reasonable redevelopment of the subject site and stream subject to the conditions enumerated below. The Preliminary Plat is approved subject to the following conditions: The applicant shall comply with the mitigation measures imposed by the Environmental Review Committee. The applicant shall alter the lot boundaries of Lot 5 and Lot 6 to qualify as pipestem lots meeting the minimum pipestem width requirements prior to short plat recording. 3. The applicant shall post the private street with "No Parking — Fire Lane" signs prior to recording of the short plat. The applicant shall place a note on the face of the short plat requiring Lot 3 to take access from the private street. The applicant shall place a note on the face of the short plat requiring Lot 9 to access from the shared driveway easement extending south from NE 24"' Street to Lot 7. 6. The applicant shall install a 6-foot solid fence along the length of the shared driveway easement prior to recording of the short plat. The applicant shall pay a Traffic Mitigation Fee of $75.00 per additional generated trip prior to short plat recording. Bartell Short Plat File No.: LUA-04-007 SHPL-H, V-H, ECF May 4, 2004 Page 9 The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single-family lot. 9. The applicant shall pay a Parks Mitigation Fee based on $530.76 per each new single-family lot. 10. The applicant will have to submit the radius -intersection dedication to the City Council.

Further, I concur that the current City regulations require only a 25-foot buffer area along the subject stream condor. Please be advised that the City is in the process of reviewing its regulations relative to stream buffer widths and these requirements could increase in the future. While your proposal will be vested under the regulations in effect at the time of the City's acceptance of a complete preliminary plat application, it is possible that the City or other reviewing agencies could require increased setbacks as habitat impact mitigation as part of the project's required environmental review. I hope this determination assists you preparing your preliminary site development plans. Please feel free to contact me or Laureen Nicolay at 425-430-7294 if you have further questions regarding this letter.

Dear Ms. Nicolay: We are requesting a pre -application review and meeting to discuss the Bartell preliminary plat. Attached, please find 5 copies of the project narrative, Vicinity map and proposed project site plan. Also attached are 5 copies of a preliminary wetland report, prepared by Larry Burnstad, of Watershed Dynamics. The primary purpose of our request is to determine if the City will accept, in principal, the findings of the wetland report. Staffs comments on the wetland report will have a significant impact on the proposed layout of the preliminary plat. Project Narrative The Bartell preliminary plat is located in the southeast comer of the intersection of Jones Ave. NE and NE 24th Street, in Renton. The property is part of a larger R-8 neighborhood, with a mixture of existing subdivisions and large lot single-family properties. The project proposal is to develop this 1.7 acre site into six (6) single family lots. The existing single- family home is proposed to remain. Of particular concern to the applicants is the status of the existing man-made pond and its associated minor stream. (see attached site plan) The pond and stream are located in the southwest corner of the property, adjacent to Jones Ave. NE. A full description of the stream, pond and its expected status are described in the attached wetland report. After reviewing the applicable City Codes, the applicant proposes to alter the existing man-made pond, by either filling it or incorporating it into a future storm water facility. A more complete description of the options is attached. In either case, the applicant is seeking confirmation of our interpretation of the applicable City codes and staff reaction to our list of design options. Other issues of interest are the required road frontage improvement, preferred access points and intersection spacing requirements. • Page 2 August 11, 2003 As described earlier, this is a proposed six lot plat. Homes are likely to range in size from 2,400 to 3,000 square feet. Using the 1998 King County Surface Water Design Manual, we would expect to design a storm water facility with a volume of 17,000 cubic feet of storage. This assumes level II flow control and an average of 10,000 cubic feet pre acre of required storage. The preferred storm water design would involve the separation of the stream from the existing pond, and the integration of the existing pond into the final storm water system. The final design will depend greatly on Staffs response to the attached wetland report. Please contact me at (253) 333-2200 with any questions. Thank you for your time. Sincerely, Hans A.

Burnstad, Senior Biologist PROJECT NAME: Bartell Residential Subdivision PROJECT NUMBER: WD 2003032 Hans - This memo is a follow-up to our July 9, 2003 field reconnaissance at the Bartell property in Renton, Washington. The purpose of the field reconnaissance was to determine the characteristics of a human -made water feature located in the southwest corner of the subject property (see attached site map). On July 9, 2003 I visited the Bartell site with you and we investigated the human -made pond and stream channel located in the southwest corner of the subject property. Our evaluation included a review of the outlet of the pond located on the east side of 108`h Avenue SE (Jones Avenue), the culvert under Jones Avenue, and the open channel on the property located west of the Bartell site. We also reviewed the channel condition upstream (south) of the subject property at the point where the stream flows into the human -made pond on the subject property. Finally, we reviewed the pond (water feature) located on the property immediately south of the Bartell site. Findings The human -altered stream channel on the property immediately south of the Bartell site was in a concrete -lined pond with concrete sidewalls that is approximately 45 feet to 50 feet long and 15 feet to 20 feet wide. The stream flowing into the upstream end of the pond was contained in a 15-inch diameter CMP (corrugated metal pipe). The pipe appeared to contain the stream flow upstream of the pond to an unknown south of the Bartell parcel's south boundary. The stream appeared to be tight -lined from the pond inlet all the way to the south side of NE 20`h Street. Draft Memo to Mr. Hans Korve, Planner — Page 1 Bartell Project, Renton, Washington The surface water out of the concrete -lined pond on the property south of the Bartell site flowed into and through a larger human -made pond located on the Bartell property. The shape of this larger pond was somewhat trapezoidal approximately 40 feet wide and 50 feet long at the widest and longest dimensions. The area around the pond has been manipulated and includes a garden, native and non-native groundcover and shrub species, and large cottonwood, cedar, and willow trees. The plant community surrounding the pond was indicative of wetland characteristics but an evaluation of the soils indicated there were no hydric soils around the pond. The pond had nearly vertically sidewalls of native soil but the pond bottom material appeared to be accumulated gravel and silt over the top of a concrete bottom. There was large gravel to cobble and quarry spalls (rip -rap) along the toe of the steep sidewalls that was, according to the owner, imported to protect the pond bank above the concrete bottom. There was a pipe/sprinkler in the center of the pond which, according to the owner, was used to aerate -the pond. There was also a 1.5-inch diameter black plastic pipe that was used to withdraw water from the pond for irrigation. The stream flow was most evident along the western edge of the pond. There was a 12-inch diameter concrete pipe located in the northwest corner of the pond that was acting as a control structure to restrict flow and maintain the water surface elevation of the pond. The water flowing out of the pond flowed into a ditch along the east edge of Jones Avenue and entered an 18-inch CMP under Jones Avenue. This culvert direct stream flow under Jones Road and into the open channel on the developed residential property that is west of the Bartell site on the opposite side of Jones Avenue. The stream channel is rip -rapped and channelized through the property on the west site of Jones Avenue. The stream flows across this property in a northwesterly direction and enters an undeveloped property in the southwest quadrant of the Jones Avenue/NE 241h Street. From the undeveloped property (which is essentially a regulated wetland) the stream flows in a northerly direction under NE 24 b Street along the east side of Interstate 405 and then northeasterly to May Creek. City of Renton Regulatory Implications f Following the reconnaissance I reviewed the Renton Municipal Code to determine if the. human- !_. i made feature on the subject property would be a "regulated" wetland within the City of Renton 1` (City). Based on my review of Title IV, Chapter 3, Section 3.050.A.7 and Section 3.050.B.7 it appears that the human -made feature (the pond) is not a regulated wetland within the City, because it is a human -made feature. Based on my evaluation of the code, however, the stream is regulated within the City and would be a Category 3 Wetland requiring a 25-foot native growth buffer between the stream and any developed areas. Although the City code does not specifically speak to streams, the definition of wetland categories appears to include streams. The code does not speak to where the buffer width is measured from, but based on my experience in other jurisdictions I would suggest that the buffer width is measured from the ordinary high water mark. Draft Memo to Mr. Mans Korve, Planner — Page 2 Bartell Project, Renton, Washington In addition, I suspect there would be a building setback between and permanent structures and the landward edge of the stream buffer, but I did not review the zoning code to determine the width of that setback area. It would be prudent to contact the City regarding building setback requirements if you are unable to find the specifications in the City code. Recommendations for Land Use Based on my field observations and my interpretation of the City code it appears that the human - made pond could be filled as part of the proposed development. The stream channel would have to remain open, however, and would very likely have to be restored (enhanced) as part of the development process. I would recommend the following as alternatives for dealing with the pond as part of the development process: ALTERNATIVE 1: Leave the pond as it currently exists and measure a 25-foot buffer based on a project of the ordinary high water mark at the southwest corner of the property where the stream enters the pond and at the northwest corner of the pond where the stream exists the pond. ALTERNATIVE 2: Fill the pond except for a stream channel along the west edge of the pond (see attached sketch). The stream channel should be designed to convey the anticipated 100-year peak flow or the maximum flow capacity of an 18-inch diameter CNW with a water surface elevation 36 inches above the pipe invert elevation. The stream channel design should assume the 18-inch culvert has inlet control and a vertical headwall with 45-degree wing -walls at the entrance of the culvert. The filling of the pond would include the removal of the 12-inch diameter pipe that currently controls the pond outlet. The channel would have to be enhanced from the inlet end of the pond at the south property line to the outlet end of the pipe currently in the northwest corner of the pond. The channel would have a bottom width approximately 18 inches to 2 feet wide, a depth of approximately 3 feet, and a top width of approximately 14 feet to 20 feet. The side slope grades (horizontal distance ) of the channel should vary from to as steep as 2:1 and as flat as 4:1. The side slopes (streambanks) would have to be revegetated with native plants (trees, shrubs, and groundcover species). ALTERNATIVE 3: Leave the pond open for use as a retention/detention pond (see attached sketch). Remove the 12-inch diameter culvert at the outlet end of the pond. Leave the existing culvert under Jones Avenue in place. Construct an earth berm along the eastern edge of the stream channel to separate the pond from the stream channel. The berm would have to be constructed to allow a channel design as described in Alternative 2 above. The R/D pond would have an outlet control structure that would discharge into the stream channel at or very near the point where the stream channel currently leaves the subject property adjacent to Jones Avenue. Draft Memo to Mr. Hans Korve, Planner — Page 3 Bartell Project, Renton, Washington ALTERNATIVE 4: Implement Alternative 3, but replace the culvert under Jones Avenue with a new culvert in the location shown on the attached sketch. The length of stream that would have to be restored or enhanced within the project area would be shorter so there may be a need to do some enhancements within the Jones Avenue right-of-way on the downstream side of the new culvert to provide sufficient mitigation. Other Regulatory Implications All of the proposed alternatives would have to be reviewed and approved by the City of Renton. The City would probably require that the preferred alternative be evaluated as part of the SEPA process being completed for the overall proposed project. It would be advisable to meet with the City of Renton to discuss the Alternatives described above before the preliminary design for the project is prepared and submitted to the City for review and approval. In addition, implementation of any of the alternatives except Alternative 1 would require a Hydraulic Project Approval (HPA) from the Washington Department of Fish and Wildlife (WDFW). WDFW requires a SEPA determination from the lead agency for the project before they will issue an HPA. The Washington Department of Ecology (WDOE) may require a 401 Water Quality Certification if the project is implemented at a time when the stream is flowing. It would appear that in "normal" years there is some flow in the creek throughout the year. I would advise contacting the owner and the surrounding neighbors to see if they have knowledge about stream flow during the late summer and early fall. With a large wetland complex and springs at the headwaters of this stream there may be year round flow in all years. I do not believe that either the U.S. Army Corps of Engineers, Regulatory Branch (Corps) or WDOE will take jurisdiction over the pond if the City determines that the pond is human -made and regularly maintained. Be aware, however, that both WDOE and the Corps can assert regulatory authority over the pond, if they choose to, since it is not isolated and it is a tributary to Lake Washington. That concludes the summary of the findings, regulatory implications, and alternative approaches to dealing with the pond on the Bartell site.

The parcel number is 3343903600, and is located in the NE quarter of Section 05, Township 25 North, Range 5 East, Willamette Meridian, Renton Washington. The site is rectangular in shape, with an existing access to NE 24th St. and is currently occupied by a single-family residence and detached outbuilding. The existing residence will remain, while the outbuilding will be demolished to accommodate the project. The property is currently zoned Single Family. The project proposes to construct a new access tract from Jones Ave. NE and NE 24th Street to serve the short plat, and install all necessary utilities and storm water facilities needed to serve the development. On -Site Drainage Analvsis The property is currently developed with a single-family residence. The site slopes to the west at approximately 6% and is predominantly grass, trees and landscaping associated with the residence. There is an existing roadside ditch along NE 24`'' St., which conveys bypass flow through a 12-inch PVC to Jones Ave. NE. The roadside ditch along Jones Ave. NE conveys on -site and upstream flows to the south. An existing onsite manmade pond is located in the southwest corner of the property_ This pond receives upstream tributary flow from approximately 48 acres. Upstream Drainage Analysis As discussed above, the existing pond receives upstream tributary flow from approximately 48 acres, including an adjacent upstream pond. These ponds are connected by a small 2-foot wide, by 2-foot deep channel approximately 15 feet in length. In addition, the site receives a small amount of tributary area from properties located to the east. This area is estimated to be 1.8 acres. It may be necessary to install a bypass drainage system to protect the proposed development from the flow from the east. .Downstream Drainage System Description The project is located within the South Kennydale Sub basin of the Lake Washington East Basin. Within '/4 mile downstream of this project, the site contributes less than 15% of the total basin drainage area; therefore, the downstream drainage way was reviewed to'/4 mile downstream from the site. For this drainage basin, the downstream drainage system was very defined. The majority of the site discharges via sheet flow to the existing roadside ditch along Jones Ave. NE adjacent to the western boundary of the property, and flows south. A small southern portion of the property discharges via sheet flow to the existing onsite pond. The pond discharges from the site within an existing 12-inch concrete pipe. This is the beginning ii❑ of the downstream analysis. The flow from the aforementioned ditch, and pond flow west in approximately 36 feet of l 8-inch corrugated metal pipe (CW). The pipe discharges into a lined 2-4 foot wide by 2-3 foot deep ditch for a distance of approximately 50 feet. At the end of this section, the channel is no longer lined, and discharges into a grass lined channel with varying size ranging form 3-6 feet wide, by 2-3 feet deep for a distance of approximately 400 feet to the northwest. The channel then enters approximately 20 feet of 24-inch concrete pipe, then 26 feet of 30-inch concrete pipe under NE 24th St. The discharge then continues north in a channel measuring approximately 10 feet wide by 6 feet deep. This channel continues north for approximately 1200 feet flowing adjacent to I405. This point is beyond '/4 mile downstream of the project site and the analysis is therefore terminated. See Exhibit C for a visual illustration of this drainage course, and Exhibit D for the Off -Site Analysis Drainage System Table. Future Site Conditions The development is proposing to install a new combined detention pond / wetpond facility, which will be discharging at the natural downstream location near the southwesterly property corner. All storm drainage facilities will be designed to City of Renton design standards. w TASK 2: Resource Review The following is a description of each of the resources reviewed in preparation of this .Downstream Analysis: Flood Plain/Floodway (FEMA) Maps The site is not within a 100-year floodplain. Refer to Exhibit E. 2. Sensitive Areas Map Folio Copies of the King County Sensitive Areas Map Folio are included as Exhibit G. According to this information, the site is not located within a Streams and 100-Year Floodplams, Wetlands, Erosion Hazard, Landslide Hazard, Seismic Hazard or Coal Mine Hazard Area. However, a minor stream tributary to May Creek has been identified on site. This stream requires a 25' buffer. The site does contain a man-made pond and has been determined to be unregulated. 3. King County Soils Survey Maps The soil underlying the site is Indianola loamy fine sand (InC). A copy of the relevant pages from the King County Soils Survey Map is included as Exhibit H. N TASK 3: Field Inspection The property is currently developed with a single-family residence and detached outbuilding. The downstream drainage system consists of a well-defined constructed open and closed system. The site slopes to the west at approximately 6% and is predominantly grass, trees and landscaping associated with the residence. A small upstream tributary area discharges to the site from the east. An existing onsite manmade pond is located in the southwest corner of the property. There was a small flow within the downstream system. Investigation of Reported or Observed Problems During Resource Review No drainage problems were identified in the review. 2. Location of Existing/Potential Constrictions or Lack of Capacity in the Existing Drainage System At the time of the site visit, there did not appear. to be any evidence of lack of capacity or constraints within the existing drainage system. 3. Identify Existing/Potential Flooding Problems At the time of the site visit, there did not appear to be any evidence of flooding or significant erosion problems within the existing downstream drainage system. 4. Identify Existing/Potential Overtopping, Scouring, Bank Sloughing, or Sedimentation There appeared to be no evidence of overtopping, scouring or bank scouring on the site or downstream. 5. Identification of Significant Destruction of Aquatic Habitat or Organisms At the time of the site visit, there where no signs of aquatic habitat or organism destruction. 6. Collect Qualitative Data on Land Use, Impervious Surfaces, Topography and Soil Types Qualitative data has been collected from resource sources and field visits. This information is included within this report. 7. Collect Information on Pipe Sizes, Channel Characteristics and Drainage Structures See Exhibit C and D for this information. IN 8. Verify Tributary Basins Delineated in Task 1 At the time of the site visit, the tributary basins described in Task 1 were verified as being accurate. 9. Contact Neighboring Property Owners in the Area No homeowners where available or contacted during the field reconnaissance for this analysis. 10. Note the Date and Weather Conditions at the Time of the Site Visit 11. The site and downstream system was visited on October 23, 2003, several days after the record one day rain total was set. At the time of the site visit, it was overcast and cool. H TASK 4: Drainage System Description and Problem Description Drainage System Descriptions: As discussed above, this site is bordered by and discharges to a defined drainage system. See Exhibit C for a visual illustration of this drainage course, and Exhibit D for the Off -Site Analysis Drainage System Table. 2. Problems: As discussed in this report, during the site visit, no recent or ongoing problems where observed within the downstream drainage course. With the installation of a new detention/water quality facility, the project should not pose significant negative impacts to the downstream drainage system. 60 TASK 5: Mitigation of Existing or Potential Problems Drainage facilities for Bartell Short Plat will be designed using the City of Renton design guidelines. The development is proposing to install a new pond detention/water quality facilities located near the southwest property corner. As there are no existing or potential problems within the downstream drainage system, no additional mitigation requirements are recommended. This level 1 analysis has provided a complete review of the downstream conditions. With implementation of the previously mentioned detention and water quality standards, the project should not pose significant negative impacts to the downstream drainage course.

The site is located to the northeast corner of N.E. 24`b Street and 108`h Avenue S.E inside the city limits of Renton, WA. The property consists of approximately 1.72 acres. There with two existing residences on the property. The existing residence to the south will be removed, the residence to the north will remain. The site is partially developed and is mostly covered with grass, shrubs and trees. 24`h Street N.E. to the west and 108`h Avenue S.E. to the north are paved with existing drainage ditches. The existing ground has slopes generally from east to west of 6%. Site soils are classified as Indianola (InC) in the King County Soils map. The site has a low point at the S.W. corner of the lot. There is an existing man made pond at this location in which an existing stream from the south flows into. The property's natural grade flows to this pond. The pond and stream drain into an existing 12" CMP then to an existing 18" CMP that crosses under 108'}' Avenue S.E. N.E. 201 Street has an existing storm drainage collection system, this system is located in the center of the road and does not collect at the low points of the cross slope. NE 241h Street has a ditch on the south side that is closed in areas with 12" pipe of various materials. The intersection of 108t' Avenue S.E. and 24`h Street N.E. is a natural low point. Roadway runoff is collected in a ditch along N.E.24t' Street. This ditch follows the roadway slope and is conveyed to another ditch along 108'' Avenue S.E. This ditch discharges at the same culvert the existing stream and pond discharges into near the S.W. comer of the property. This ditch in order to discharge in the culvert crossing has a opposite slope of the roadway. 0 SECTION IV DETENTION FACILITY DESIGN gravelly coarse sand to very gravelly loamy sand. Depth. to the IIC horizon ranges from 18 to 36 inches. Some areas are up to 5 percent included Alderwood soils, on the more rolling and undulating parts of the landscape; some are about 5 percent the deep, sandy Indianola soils; and some are up to 25 percent Neilton very gravelly loamy sands. Also included in mapping are areas where consolidated glacial till, which characteristically underlies Alderwood soils, is at a depth of S to 1S feet. Permeability is rapid. The effective rooting depth is 60 inches or more. Available water capac- ity is low. Runoff is slow, and the erosion hazard is slight. This soil is used for timber and pasture and for urban development. Capability unit IVs-1; woodland group 3f3. Everett gravelly sandy loam, 5 to 15 percent slopes (EvQ .--This soil is rolling. Areas are irregular in shape, have a convex surface, and range from 25 acres to more than 200 acres in size. Run- off is slow to medium, and the erosion hazard is slight to moderate. Soils included with this soil in mapping make up no more than 25 percent of the total acreage. Some areas are up to 5 percent Alderwood soils, which overlie consolidated glacial till; some are up to 20 percent Neilton very gravelly loamy sand; and some are about 15 percent included areas of Everett soils where slopes are more gentle than 5 percent and where they are steeper than 15 percent. Ibis Everett soil is used for timber and pasture and for urban development. Capability unit VIs-1; woodland group 3f3. Everett gravelly sandy loam, 15 to 30 percent slopes (EVD).--This soil occurs as long; narrow areas, mostly along drainageways or on short slopes between terrace benches. It is similar to Everett gravelly sandy loam, 0 to 5 percent slopes, but in most places is stonier and more gravelly. Soils included with this soil in mapping make up no more than 30 percent of the total acreage. Some areas are up to 10 percent Alderwood soils, which overlie consolidated glacial till; some are up to 5 percent the deep, sandy Indianola soils; some are up to 10 percent Neilton very gravelly loamy sand; and some are about 15 percent included areas of Everett soils where slopes are less than 15 percent. Runoff is medium to rapid, and the erosion hazard is moderate to severe. Most of the acreage is used for timber. Capa- bility unit VIe-1; woodland group 3f2. Everett-Alderwood gravelly sandy loamy, 6 to 15 percent slopes (EwC).--This mapping unit is about equal parts Everett and Alderwood soils. The soils are rolling. Slopes are dominantly 6 to 10 percent, but range from gentle to steep. Most areas are irregular in shape and range from 15 to 100 acres or more in size. In areas classified as Everett soils, field examination and geologic maps indicate 16 the presence of a consolidated substratum at a depth of 7 to 20 feet. This substratum is the same mate- rial as that in the Alderwood soils. Some areas are up to 5 percent included Norma, Seattle, and Tukwila soils, all of which are poorly drained. Runoff is slow to medium, and the erosion hazard is slight to moderate. Most of the acreage is used for timber. Capabil- ity unit VIs-1; woodland group 3f3. Indianola Series The Indianola series is made up of somewhat excessively drained soils that formed under conifers in sandy, recessional, stratified glacial drift. These undulating, rolling, and hummocky soils are on terraces. Slopes are 0 to 30 percent. The annual precipitation is 30 to 55 inches, and the mean annual air temperature is about 50' F. The frost - free season is 150 to 210 days. Elevation ranges from about sea level to 1,000 feet. In a representative profile, the upper 30 inches is brown, dark yellowish -brown, and light olive - brown loamy fine sand.

The existing house to the north will remain leaving 8 build able lots_ An Access Tract will be provided for access to the existing home. Lots that front along the 2 streets will have driveway access. Lots in the interior will have a dedicated access tract to them.. An open detention pond and swale will be constructed to provide water quality and quantity control. The existing stream will be separated from the existing pond and the stream channel will be dressed along the frontage. Additional paving, curb, gutter and sidewalk will be added to N.E. 24`h Street and 108`'' Avenue S.E. along the property frontage. The offsite roadway and offsite drainage will be bypassed. According to Mr. Greg Reiman of King County Storm Water Management, the 1990 manual allows offsite storm water to be bypassed if the total offsite is greater than 50% of the onsite flow. A collection system will be installed along the frontage lots to collect the onsite runoff and route it to the pond. Detained storm water will discharge to the existing 18" CMP culvert crossing 108t' Avenue S.E. The road and offsite runoff will also be routed to the 18" CMP culvert.

RECOMMENDATION: Authorize the Mayor and City Clerk to execute the Engineering Consultant Agreement, in the amount of $234,292.00, with HDR Engineering, Inc., to perform the pre -design of Well 5A Water Treatment Improvements Phase II project. BACKGROUND SUMMARY: On March 17, 2006, the City entered into consultant contract CAG-06-045 with HDR, Engineering Inc., to perform the first phase of this project, which consisted of bench scale testing and a pilot study to determine the best treatment method to improve the water quality of Well 5A, located at NE 241" Street and Jones Avenue NE, in the Kennydale area (see attached map). On July 20, 2006, HDR Engineering, Inc. completed the Phase I study, and determined the most efficient method and appropriate technologies to treat the water of Well 5A. Water from Well 5A contains naturally occurring iron, manganese, hydrogen sulfide, and ammonia, which cause taste and odor problems and also stains customers' laundry, dishes and house plumbing fixtures. As such, the City will not supply water from Well 5A to its customers. Council/Well 5A Pre -Design November 27, 2006 Page 2 of 2 Under this consultant agreement, HDR Engineering, Inc. will perform the second phase of the project, which consists of the pre -design study and the preparation of the Pre -Design Report for submission to the Department of Health for approval as required under WAC 246-290-110. The scope of work for the consultant agreement also includes: • Topographic and boundary lines survey of Well 5A site. • Geotechnical investigation of site to determine soil characteristics for structural and architectural design of the additional treatment facility. • Development of basis of design for the treatment system to meet the water quality goals and objectives. • Determination of the hydraulic conditions of the existing well pumps and distribution system piping. • Development of basis of design for electrical system, instrumentation and control elements. • Development of site and civil plans for the project. • Pre -Design Report for submission to the Department of Health and related applications for permit and project approval. The Water Utility has budgeted $250,000.00 in its 2006 Capital Improvement Program budget, account no. 425.000500.018.5960.0034.65.055565, to cover costs related to this consultant agreement in the amount of $234,292.00. After the completion of this contract for Phase II Pre -Design, the Water Utility will be coming back to Council to request the approval of funding for separate contracts with HDR Engineering, Inc. for the next phases of the project, which consist of: • Phase III — Design and preparation of construction plans, specifications, and cost estimate for construction bid package (2007). • Phase IV — Construction of water treatment facility and plant start-up (2008-2009). The Water Utility's planning level cost estimate (2006) for the entire project, Phases I to IV, is about $4,250,000. CONCLUSION: Well 5A is an important source of water supply to the City, the well can produce 1,500 gallons per minute or about 2.16 million gallons of water per day. Additional water treatment is needed to improve the water quality of Well 5A in order to meet safe drinking water standards and the City's goal to deliver good water quality to its growing number of water customers. In accordance with City policies on engineering consultants' selection, the Water Utility selected HDR Engineering, Inc. as the most qualified firm to perform the various phases for the design of this project.

RECOMMENDATION: Authorize the Mayor and City Clerk to execute the Engineering Consultant Agreement, in the amount of $234,292.00, with HDR Engineering, Inc., to perform the pre -design of Well 5A Water Treatment Improvements Phase II project. BACKGROUND SUMMARY: On March 17, 2006, the City entered into consultant contract CAG-06-045 with HDR, Engineering Inc., to perform the first phase of this project, which consisted of bench scale testing and a pilot study to determine the best treatment method to improve the water quality of Well 5A, located at NE 241h Street and Jones Avenue NE, in the Kennydale area (see attached map). On July 20, 2006, HDR Engineering, Inc. completed the Phase I study, and determined the most efficient method and appropriate technologies to treat the water of Well 5A. Water from Well 5A contains naturally occurring iron, manganese, hydrogen sulfide, and ammonia, which cause taste and odor problems and also stains customers' laundry, dishes and house plumbing fixtures. As such, the City will not supply water from Well 5A to its customers. Council/Well 5A Pre -Design November 27, 2006 Page 2 of 2 Under this consultant agreement, HDR Engineering, Inc. will perform the second phase of the project, which consists of the pre -design study and the preparation of the Pre -Design Report for submission to the Department of Health for approval as required under WAC 246-290-110. The scope of work for the consultant agreement also includes: • Topographic and boundary lines survey of Well 5A site. • Geotechnical investigation of site to determine soil characteristics for structural and architectural design of the additional treatment facility. • Development of basis of design for the treatment system to meet the water quality goals and objectives. • Determination of the hydraulic conditions of the existing well pumps and distribution system piping. • Development of basis of design for electrical system, instrumentation and control elements. • Development of site and civil plans for the project. • Pre -Design Report for submission to the Department of Health and related applications for permit and project approval. The Water Utility has budgeted $250,000.00 in its 2006 Capital Improvement Program budget, account no. 425.000500.018.5960.0034.65.055565, to cover costs related to this consultant agreement in the amount of $234,292.00. After the completion of this contract for Phase II Pre -Design, the Water Utility will be coming back to Council to request the approval of funding for separate contracts with HDR Engineering, Inc. for the next phases of the project, which consist of: • Phase III — Design and preparation of construction plans, specifications, and cost estimate for construction bid package (2007). • Phase IV — Construction of water treatment facility and plant start-up (2008-2009). The Water Utility's planning level cost estimate (2006) for the entire project, Phases I to IV, is about $4,250,000. CONCLUSION: Well 5A is an important source of water supply to the City, the well can produce 1,500 gallons per minute or about 2.16 million gallons of water per day. Additional water treatment is needed to improve the water quality of Well 5A in order to meet safe drinking water standards and the City's goal to deliver good water quality to its growing number of water customers. In accordance with City policies on engineering consultants' selection, the Water Utility selected HDR Engineering, Inc. as the most qualified firm to perform the various phases for the design of this project.

Wilson, Water Utility Engineer (ext. 7295) SUBJECT: Consultant Agreement for Well 5A Water Treatment Improvements Phase I — Bench Scale and Pilot Plant Study ISSUE: Should Council approve an engineering consultant agreement with HDR Engineering, Inc., to perform water quality testing and pilot plant study to determine the best treatment method to improve the water quality of Well 5A? RECOMMENDATION: Authorize the Mayor and City Clerk to execute the Engineering Consultant Agreement with HDR Engineering, Inc., in the amount of $59,450.00, to perform bench scale testing and pilot study to determine the best method to improve the water quality of Well 5A. BACKGROUND SUMMARY: Water from the City's Well 5A, located at NE 24`h Street and Jones Avenue NE (see attached map), contains naturally occurring iron, manganese, hydrogen sulfide and ammonia. The current water treatment method does not produce finished water meeting aesthetic water quality standards. The water has a bad taste and odor, and stains customers' laundry, dishes and plumbing fixtures, therefore the City has not supplied water from Well 5A to our customers since the redevelopment of the well and the construction of the pump station in 1991. Well 5A can produce 1,500 gallons per minute or 2.16 million gallons of water per day, and it is an important source of water supply for the City, as more customer connections are added to our water system. In 2005, the Water Utility solicited proposals from engineering consultant firms according to City Policy #250-02, Bidding and Contracting Requirements, for public CounciMell 5A Study February 24, 2006 Page 2 of 2 works projects. The selection committee reviewed proposals from four firms, interviewed the top two ranked firms and selected HDR Engineering, Inc. as the firm most highly qualified to provide the required services. Under this contract for Phase 1 of the project, the consultant will conduct a bench -scale and pilot plant study to determine the most appropriate treatment technologies to improve the water quality of Well 5A. The study will use both laboratory analyses and a "Taste and Odor Panel" (a group of about 10 people who will rate the taste and odor of the treated water) to evaluate the effectiveness of various treatment technologies. The Water Utility has budgeted $350,000 in our 2006 Capital Improvement Program budget, to cover costs related to this consultant contract and costs related to the anticipated next phase for the design of the project. The estimated cost plus fixed fee contract with HDR Engineering, Inc. for the Phase 1 study is $59,540.00. In addition to Phase 1 study contract with HDR Engineering, Inc. the City will hire a pumps -contractor to remove the existing large pump motor and columns from the well casing. The pumps -contractor will install a small, low -volume pump in the well casing with temporary power to provide the pilot plant with a continuous supply of water without overflowing the drainage system. Upon the completion of the pilot study, the pumps -contractor will remove the temporary low volume pump and re -install the original pump motor and columns in the well casing. The estimated cost of the contract with the pumps -contractor is $30,000.00. After the completion of this consultant contract for Phase 1 study, the City will be able to select the most efficient treatment train option to meet the finished water quality goals. Although the City's selection committee has selected HDR Engineering, Inc. to provide engineering services for the next phases of the project, the Water Utility will be coming back to Council to request the approval of separate contracts with HDR Engineering, Inc., along with the approval of funding for each phase of the project. The next phases of the project consist of: • Phase 2 — Treatment technology selection and development of preliminary cost estimate (2006). • Phase 3 — Design and preparation of construction plans, specifications, cost estimate and construction bid package (2007). • Phase 4 — Construction and plant start-up (2007 to 2008). The Water Utility's planning level cost estimate for the entire project, phases 1 to 4, is about $4,250,000. CONCLUSION: The bench scale testing and pilot -study for Well 5A is needed in order to determine the best treatment method to improve the water quality of this important source of water supply. The study will allow the City to evaluate the efficacy of treatment options, and costs related to the design and construction of additional water quality treatment facility for Well 5A.

This soil is described as an extensively drained soil, formed under conifers in sandy, recessional, stratified glacial drift. Surface site soils observed during the survey were mostly sand and silt fill material, mixed extensively with riprap along the stream banks. Riprap and fill material provide the basic stability observed in many of the surveyed reaches of Clover Creek (see Photo C32). Remaining banks consist of imported fill material or wooden railroad ties (see Photo C30). Field crews observed short segments of undercut bank at the bends in Clover Creek upstream of 1-405, but none in the surveyed reaches downstream of 1-405, Upstream of 1-405, at the time of the survey in April 2004. the average wetted width of the surveyed channel was 3.1 feet and the average wetted depth was 0.5 feet. Downstream of 1-405, the average wetted width of the surveyed channel was 4.3 feet and the average wetted depth was 0.5 feet. The bankfull width downstream of 1-405 was approximately 13.5 feet. Because Clover Creek's banks are extensively modified and influenced by the stream's location along the 1-405 sound walls, the bankfull measurements were made from the top of the artificial bank. The average depth at bankfull was estimated to be 1.6 feet, with a maximum depth of 1.6 feet. Substrate Table 4-6 (see Page 4-56) summarizes substrate composition in Clover Creek, based on the length of each habitat unit (excluding culverts) and presents the percentage of the total habitat length for the dominant and secondary substrates. The dominant stream channel substrate in Clover Creek is sand, followed by siltiorganics. The secondary substrate types, in descending magnitude of coverage, include sand, small gravel, and silt/organics. Spawning gravel embeddedness by surface fines ranged from 50 to 75 percent throughout the surveyed segment. In areas of slow flow, such as in runs and pools, the field crew observed extensive sediment deposits. Large Woody Debris and Pool Quality Field crews observed one instance of large woody debris, a piece of red alder, approximately 20 feet long and 8 inches in diameter, within the surveyed reach, near the upstream end of Habitat Unit 14 (see Figure 4-2, Sheet 3 found at the end of Section 4). They also noted three pools within the surveyed reach of Clover Creek. Only one of these pools (Habitat Unit 11) has sufficient size and depth to provide suitable cover for fish_ The remaining pools (Habitat Units 2 and 4) are small and shallow. Run habitat within the surveyed reach upstream of 1-405 may provide some potential resting habitat for fish. Riparian and Aquatic Vegetation The width of the riparian corridor along Clover Creek varies from 5 to 100 feet throughout the surveyed area in relation to its proximity to 1-405 sound walls. It lacks large trees for large woody debris recruitment to the stream (see Photos C33, C34, and C35). In some areas of the surveyed reach, the riparian corridor consists of landscaped grass lawn extending over 100 feet from the right bank (Habitat Units 9, 10, 11, and 1 Z see Photo C35). These areas represent the only segments of the riparian corridor over 40 feet wide. Riparian vegetation within the surveyed reaches consists of non-native 1-405, SR 169 to 1-90 - Renton to Bellevue Project Fish and Aquatic Resources Discipline Report September 2006 4-11 June 2007 Purpose and Approach The purpose of Phase 3 of the Well 5A Water Treatment Improvements Project is to prepare the final design and construction documents for the City of Renton's planned Well 5A treatment facility.

Wilson, Renton Water Utility From: Greg Pierson Project: Well 5A Treatment Improvements CC: Milt Larsen, K/J Date: January 24, 2007 Job No: 51403 RE: Considerations for Retaining or Removing the Existing Well Building The purpose of this memo is to outline some key considerations to assist with the City's decision as to whether to remove or retain the existing well building at Well 5A as part of the water treatment improvements project. Attached are two conceptual site sketches of the well site to help illustrate the points made in this memo. Figure 1 shows a possible site layout with the well building removed. Figure 2 shows a possible building layout that incorporates the existing well within the new treatment building. The size and configuration of the new treatment building is approximate based on preliminary facility sizing requirements and is not intended to represent our recommended configuration at this time, however I believe that the overall footprint size of this building will be fairly close to that shown in the figures. The key considerations are outlined in the following table and the relative advantages and drawbacks for each are noted in terms of removing the existing building.

Wright Page 6 of 10 Well 5A Treatment Facilities City of Renton, Washington 3.13 - Electrical Kennedy/Jenks Consultants Electrical design shall comply with the NEC. The primary issue is that a minimum of 42-inch clearance in front of panels 3.14 - Handicap Access The Facility is normally unoccupied. Operation and maintenance personnel enter only periodically to perform operation/maintenance tasks. The Treatment Building is not required to meet accessibility requirements. The Washington Amendments to the IBC indicates that all facilities that are normally occupied must be accessible to the physically handicapped. Exceptions to this include areas such as equipment spaces, attics, crawl spaces, and similar spaces. The Treatment Building is considered an equipment space. 3.15 - Special Design Considerations Mobile Stand-by Generator poses several design issues as follows: 1. Flue Exhaust: A flexible metal flue fitting will be required for exhaust gas. The exhaust gas will be ducted to the exterior. Power assist will be required if the exhaust run is over 10 feet. 2. Fuel Tank Vent: Flexible vent fitting and vent pipe will be required to vent the tank to the exterior. 3. Fire: Fire sprinklers are required in H-3 occupancies or fuel storage over 120 gallons. 4. Containment: The fuel tank will most likely be double contained. 20 minutes of fire sprinkler water will need to be contained or controlled (drain to a safe area outside or inside). This typically amounts to 1,000 to 1,500 gallons of water. 5. Building Construction: Fire walls are normally required between hazardous uses and other occupancies. This normally not a major cost issue, but windows and door openings will be limited. 6. Ventilation: Connection to the exhaust louver shroud will be the most cumbersome part of the operation. The cooling system on the generator will not function adequately without a duct to the exterior. 7. Egress: a minimum of two swinging doors with panic hardware may be required depending on the layout of the space. 8. Noise: Noise from operation of the generator will be difficult to mitigate. Roll -up and overhead doors are poor sound attenuators. Expect noise levels on the outside, adjacent to the roll- up/overhead door to be 75 to 80 dBA. 9. Electrical: No unusual electrical code issues associated with the operation. Clearances around panels will need to conform with the NFPA. Preliminary: 12 April 2007 K/J Project: 0697005.01 By: D.

' ^ f 7� /C�j /! �/� TIME LIMITATIONS Description of Work Aquifer testing of a replacement well for the City of Renton Well No. 5 will consist of the following: - An 8-hour step -rate pump test will be performed in four stages (two hours at each stage) in which the well will be pumped at increasing discharge rates to a maximum of 1500'gpm (3.3 cfs). - Following the step -rate pump test, the well will be pumped at a constant discharge for 40 hours at a maximum rate of 1500 gpm (3.3 cfs). During the aquifer test, it is proposed that the groundwater be discharged to a small stream (name unknown) that borders the property and ultimately discharges to Lake Washington (map attached). The attached memo addresses potential effects of increased discharge in the stream on fish migration patterns in Lake Washington. These were evaluated by Forrest Olson, a CH2M HILL fisheries biologist, who has visited the site. It is also proposed that hay bales be placed along the stream channel to reduce erosion from the increased discharge. nu ri." IT ` jf D F- KENN ✓OALF NTTNT ..

The City of Renton will be pump testing well #5A which will require discharging up to 1500 gpm for 48 hours into the stream. The pumping will be terminated quickly to facilitate the water table recovery test. Of concern is the possibility of adult salmon, probably coho, entering the stream at the higher flow and then becoming stranded when the water level drops. The stream is not cataloged as a salmon utilized stream nor is it a tributary of one (Williams et al. 1975). It enters Lake Washington directly. Flow in the stream was approximately 500 gpm. There has been no rainfall for several days. Approximately 50 feet from its mouth the stream passes through an area of tangled quackgrass and cattails where the flow is spread over a width of 15 feet for about 30 feet of stream length. Depth is not more than two inches. This section is clearly not passable by adult salmon due to its shallowness and thick grass. In my opinion this section would also be impassable with an additional 1500 gpm of flow. Another impassable barrier at this flow occurs at the upper end of the culvert passing under the railroad tracks. A stick jam has raised the streambed approximately three feet in elevation above the culvert causing water to fall and disperse through the sticks. This location would probably remain a migration barrier at the higher flow (4 cfs) due to the lack of a plunge pool and the disposal of flow through the sticks. CKWILL Millard Deusen, Department of Fisheries Page Two December 28, 1987 S22077.A2 In conclusion, I believe it is highly unlikely that adult salmon could pass upstream more than 50 feet from the lake if flows are increased by 1500 gpm. If fish entered this 50 foot section they would have no difficulty returning to the lake if the flow dropped. It is also worth noting that the proposed flow increase during pump testing is probably no greater than what occurs naturally during storm events.

An APA, as defined in the City of Renton's proposed aquifer protection ordinance, is thelportion of an aquifer within the zone of potential capture , including any con- tributing recharge areas, for a well or well field owned by the City of Renton. An APA may be subdivided into two aqui- fer protection zones: o Zone 1--The land area situated between a well or well field owned by the City of Renton and the 365-day groundwater travel time contour. o Zone 2--The land area situated between the 365-day groundwater travel time contour and the boundary of the APA, except when the well or well field is naturally protected by overlying geologic strata. In cases where a well or well field is naturally protected, the City of Renton may choose not to subdivide an APA into two zones. Zone 2 will then be defined as the land area situated between a well or well field owned by the City of Renton and the boundary of the APA. APPROACH Ideally, the boundaries of an APA should be delineated based on the results of a hydrogeologic investigation and ground- water monitoring study, as was done for the City of Renton well field (CH2M HILL 1984 and 1988a). A hydrogeologic in- vestigation provides information on aquifer characteristics (e.g., thickness and transmissivity), aquifer boundaries, and recharge areas. Monitoring of groundwater elevations during pumping provides information on rates and directions of groundwater movement and the areal extent of the zone of potential capture. When such information is not available, the approximate boundaries of an APA can be calculated with a groundwater model. 1The zone of potential capture is that portion of an aquifer wherein all groundwater would ultimately flow to a well or well field if it were pumped continuously. se5801/025/1 A model -based approach was used for Wells 4 and 5A because limited hydrogeologic information exists in the vicinity of these wells and no groundwater monitoring was conducted to define the zone of potential capture. The following discus- sion defines several concepts important to understanding the modeling approach. When a well is pumped, a cone of depression forms around the well. If the 1well is pumping in an aquifer with uniform regional flow , a flow pattern typical of that shown in Fig- ure 1 will be created. An important feature of this flow pattern is the groundwater divide. The groundwater divide bounds the portion of an aquifer supplying groundwater to a well (Bear, 1979). The groundwater divide will propagate outward from the well until regional inflow equals the pump- ing rate of the well (i.e., until steady-state conditions are reached). Thus, the position of the groundwater divide will change depending upon the well pumping rate and the regional groundwater flow rate. The area encompassed by the groundwater divide is called the "zone of potential capture." Theoretically, all of the groundwater within the zone of potential capture will ulti- mately be captured if the well is pumped continuously. Practically, most wells are pumped intermittently and ground- water near the boundary of the zone of potential capture may never reach the well because the time for it to travel to the well is longer than the duration of pumping. Thus, the actual zone of capture for a well is generally smaller than the zone of potential capture. For an aquifer and well satisfying the following conditions: o Homogeneous and isotropic aquifer materials o Confined aquifer conditions o Aquifer infinite in areal extent o Constant aquifer thickness o Uniform regional groundwater flow o Single pumping well o Constant pumping rate it is possible to estimate the approximate geometry of the zone of potential capture. The maximum width of the zone of potential capture, Y, can be estimated as (Bear, 1979; Todd, 1980; and McWhorter and Sunada, 1977): 1A uniform regional flow field is one where the rate and direction of groundwater movement is the same everywhere (see Figure 1). se5801/025/2 WEU EOUIPOTE 4- 4- 4- UNIFORM 4--- REGIONAL FLOW 4- ER 4- -- FIGURE I A SINGLE PUMPING WELL IN UNIFORM FLOW, (Source: Bear, 1979) where Y = Q/Ti (1) Q = well pumping rate, gallons per minute (gpm) T = aquifer transmissivity, gallons per day per foot (gpd/ft) i = hydraulic gradient, feet/feet The maximum distance the zone of potential capture extends regionally downgradient of the pumping well, X, can be esti- mated as: where X = Q/27Ti 7 = 3.141593... (2) While the equations described above provide the general geom- etry of the zone of potential capture, they do not provide the location of the entire boundary. The location of the boundary was determined using RESSQ, a semianalytical ground- water model that calculates the paths groundwater would fol- low (i.e., the streamlines in Figure 1) under the assumptions listed above (Javandel et al., 1984). ASSUMED HYDROGEOLOGIC AND PUMPING CONDITIONS Table 1 lists the key assumptions made in calculating the geometry of the zone of potential capture for Wells 4 and 5A. These assumptions are compared with actual hydrogeologic and pumping conditions. The equations listed above and RESSQ require that the fol- lowing parameters describing hydrogeologic and pumping con- ditions be estimated: o Well pumping rate o Transmissivity o Hydraulic gradient Table 2 lists the values that were selected for each param- eter. APA DELINEATION Table 3 provides the general geometry of the zone of poten- tial capture for Wells 4 and 5A based on the assumed hydro - geologic and pumping conditions (see Table 2).

Apparent transmissivity measured at Well 5 was 30,000 gpd/ft. Use of transmissivity from lower end of the range leads to a more conservative capture zone. Hydraulic Gradient Magnitude 0.005 ft/ft Wells 4, 5, 6, and 7 Limited data available on water -level data regional water levels; water -level data obtained from drillers logs. Direction Well 4 Between Northwest Wells 4, 5, 6, and 7 Uncertain because of local and Southwest water -level data topography and limited regional water -level data; consistent with regional trend.

Figure 2 shows the extent of the zone of potential capture for Well 5A; the line indicates the position of the ground- water divide as calculated by RESSQ. Figure 3 shows the extent of the zone of potential capture for Well 4. Because of uncertainties associated with the direction of the regional gradient (see Table 2), the City of Renton decided to assume that the gradient could be in any direction between northwest and southwest. Thus, the zone of potential capture for Well 4 includes the area bounded by the groundwater divide assuming a gradient in either direction and everything in between. It is important to recognize that theoretically the zone of potential capture extends regionally upgradient (i.e., to the east) an infinite distance. Practically, this is not the case. Aquifer boundaries will ultimately determine the extent of the capture zone. Because the hydrogeologic in- formation required to define aquifer boundaries upgradient of Wells 4 and 5A is not available, the actual upgradient boundary of each capture zone cannot be determined. As will be discussed below, the upgradient or eastern -most boundary was arbitrarily established as part of the APA delineation process. Delineation of an APA for each well involved a three -step process. 1. The upgradient or eastern -most APA boundary was assumed to be the Renton city limits because there is no hydro - geological information to suggest the presence of any aquifer boundaries between either well and the city limits. In addition, the proposed aquifer protection ordinance is only enforceable within the City of Renton. 2. The remainder of the APA boundary was assumed to be equivalent to the calculated capture zone boundary (see Figures 2 and 3). 3. The final APA boundary was modified, where necessary, to follow property ownership boundaries so that a legal description of the APA boundary could be prepared. In general, the APA boundary was modified to follow street centerlines and section lines. The APA boundary was not delineated at the individual lot and parcel level because of limits in the resources available to develop the legal description. Figure 4 shows the final APA boundaries for Wells 4 and 5A. Because the APA boundaries for both wells overlap with the se5801/025/4 APA boundary for the well field (CH2M HILL, 1988a), they were combined to obtain an overall APA boundary. As Figure 4 illustrates, the APAs for Well 4 and Well 5A were defined entirely as Zone 2 areas for purposes of aquifer protection. Both wells are relatively deep and are naturally protected by overlying geologic strata. se5801/025/5 REFERENCES Bear, J. Hydraulics of Groundwater, McGraw-Hill, Inc., New York, NY. 1979.

SUMMARY AND PURPOSE OF REQUEST. REPORT DATE: June 21, 2005 Project Name Roberson Short Plat Owner/Applicant William R Roberson 16834 31 st Place S SeaTac, WA 98188 File Number LUA-05-050, SHPL-A, ECF Project Manager Nancy Weil, Senior Planner Project Description The applicant is requesting Environmental (SEPA) Review and Administrative Short Plat Review for the subdivision of a 1.03-acre site zoned Residential -8 (R-8) into four lots. The lots are intended for the eventual development of detached single family homes- lots ranging in size from 5,960 sq. ft. to 17,451 sq. ft. The site contains an approximately 12,304 square foot wetland area and a regulated stream; each would have the required 25 ft. buffer. After required deduction for critical area, the net density for the proposal is 5.4 du/ac. One existing single-family dwelling is to remain on proposed Lot 1. The site has public road frontage on Jones Avenue NE, NE 24th Street and High Avenue NE. Each lot will have direct public road frontage. Project Location 1601 NE 24th Street Project Location Map 05-050shpl-ercrpt.doc 1* City of Renton P/B/PW Department Administrative Land Use Action • REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 2 1. Project Description/Background The proposal is to subdivide the existing 1.03-acre site into 4 lots retaining the existing two-story single-family dwelling at the northwest corner of the site. The site is Residential-8 (R-8) zoning designation. A stream and a Category 3 wetland are located mainly in the eastern third of the site. The stream flows south to north eventually draining to Lake Washington. This land use application is vested to the code requirements prior to the adoption of the Critical Areas Ordinance in May of 2005. The site is located to the south of NE 24th Street, fronting High Avenue NE to the west and Jones Avenue NE to the east. All lots have direct public road frontage. The lots are proposed at the following sizes: Lot 1 is 5,980 square feet, Lot 2 is 10,721 square feet, Lot 3 is 11,504 square feet and Lot 4 is 17,564 square feet. The buildable lot areas for Lots 2, 3 and 4 will be affected by the Native Growth Protection Area Easement to be recommended by staff to ensure protection of the wetland and buffer area. With the deduction of the critical areas the net square footage of Lots 2, 3 and 4 are as follows respectively: 4,795 square feet, 6,920 square feet and 5,625 square feet. All lots still exceed the minimum 4,500 square feet required for lot size in R-8 zoning. The site contains approximately 12,304 square feet of protected wetland area and 9,185 square feet of required buffer (25 foot buffer). Only the actual wetland area is deducted for density calculations. Therefore the net acreage of the site is 0.74 thus resulting in a net density for 4 lots of 5.4 du/ac (4/0.74 = 5.4). The topography of the subject is site flat to rolling with an average slope of 3 to 4 percent from southwest to northeast down towards Jones Avenue NE. The developable portion of the site is vegetated primarily with trees and grass. The portion of the site containing the protected wetland meets the criteria as forested Category 3. The applicant has proposed to remove 10 trees, none in the protection area. The protected wetland and stream are included in the City's definition of critical areas; therefore the proposed short plat is subject to the State Environmental Policy Act (SEPA) review. The developed site will discharge all stormwater not infiltrated to the stream, which bisects this site. The hydrology of the wetlands associated with this stream will be maintained by directing surface flows to the wetlands from the new lots. The project will add less than 5,000 sq ft of pollution generating impervious surfaces and therefore water quality controls will not by required. Per King County Soils Survey, the site contains Indianola Series loamy sand soils (hydrologic class "A", which are soils suitable for infiltration. During construction, individual infiltration facilities for each lot will be provided. The existing home shall be retrofitted with infiltration facilities. 2. Environmental Review In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Impacts The proposal was circulated and reviewed by various City Departments and Division to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: Earth Impacts: The site can be described as flat to rolling with an average slope of 3 to 4 percent. Staff waived the submittal requirement for a geotechnical report unless required at the construction and/or building permit review. The site consists of Indianola Series loamy soils (hydrologic class "A") per King County Soils Survey. The preparation of the site is expected to require minor grading with no exporting of material. If any imported fill material is found necessary, it will be acceptable material for road and utility construction. Construction is estimated to take 90 to 120 days to complete. In order to reduce the potential for erosion and control sedimentation to the site and to adjacent properties, staff recommends the following two mitigation measure that the project be designed and comply with the Department of Ecology's (DOE) Erosion and Sediment Control Requirements, outlined in Volume II of the 2001 Stormwater Management Manual and temporary erosion control mearures. shpltrpt. doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 3 Mitigation Measures: • Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. A note to this effect shall be placed on the face of the final short plat map. This project shall comply with the Department of Ecology's (DOE) Erosion and Sediment Control Requirement, outlined in Volume II of the 2001 Stormwater Management Manual during site preparation, and during future building construction. A note to this effect shall be placed on the face of the final short plat map. Nexus: SEPA Environmental Regulations; Vol. II 2001 DOE Stormwater Management Manual. Surface Water Impacts: There is a storm drainage ditch on the south side of NE 24th Street however no improved drainage facilities front this proposed site. The project is in the South Kennydale Creek drainage basin. The applicant has submitted a Preliminary Technical Information Storm Drainage Report prepared by GeoDatum, Inc., dated April 7, 2005 with the land use application. The existing surface water runoff from the site drains directly into the unclassified stream that bisects the property south to north. The developed site will discharge all stormwater not infiltrated to this stream. The hydrology of the wetlands associated with this stream will be maintained by directing surface flows to the wetlands from the new lots. The project will add less than 5,000 square feet of pollution generating impervious surfaces and therefore water quality controls will not by required. The report discusses that a Level 1 downstream analysis was conducted. From the north side of the site, a 25-inch culvert conveys the stream under NE 24th Street. The study area extended a quarter of a mile downstream from the site where the open ditch enters a tight line conveyance system and passes under Interstate 405 before continuing to Lake Washington. The banks of the stream were observed to be well vegetated and stable. The report concludes the drainage system appears to have adequate capacity with no problems except for minor sedimentation of the culvert under NE 24th Street, which should be cleaned out as part of the proposed short plat improvements. Staff recommends this clean out be a mitigation measure of the short plat. The project is to be designed per the 1990 King County Surface Water Drainage Manual. Mitigation Measures: • The applicant shall follow the recommendation of the Preliminary Technical Information Report prepared by GeoDatum, Inc dated April 7, 2005 for the cleaning out of sedimentation of the culvert under NE 24th Street adjacent to the site. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division and be completed prior to the issuance of construction/utility permits. Policy Nexus: SEPA Environmental Regulations Wetland/Stream Impacts: The applicant submitted a Wetland Delineation and Stream report as prepared by the Riley Group, Inc dated January 15, 2005. The report indicated that .a Category 3 regulated wetland is located on -site and a seasonal drainage course also exists on site. In order to preserve the protected wetland and stream area, staff will recommend as a condition of short plat approval that a Native Growth Protection Easement be recorded over the wetland, stream and buffer area. The wetland was delineated as 12,304 square feet in area. The report states the wetland meets the forested Category 3 criteria including that it is larger than 5,000 square feet. Vegetation in the wetland area is forest dominated by black cottonwood, Pacific willow and red alder with Himalayan blackberry under story. The classification of the site is consistent with the wetland on the property to the west. A 25-foot buffer from the delineated wetland edge would be provided. This land use application is vested to the code requirements prior to the adoption of the new Critical Areas Ordinance in May of 2005. Therefore, streams are regulated under the Tree Cutting and Land shpltrpt. doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 4 Clearing Ordinance. No tree cutting, land clearing or groundcover management except for enhancement or other wise permitted is allowed within a minimum of 25 feet of the ordinary high water mark (OHWM) of creeks or within 15 feet of the top of the bank of same. The stream and buffer are proposed to be within a native growth protection area easement to protect the critical area. To ensure that the stream and wetland buffer remains undisturbed during construction and after site development, staff recommends the following mitigation measures: Install silt fencing with brightly colored construction flags to indicate the boundaries of the wetland and stream/creek buffer prior to the issuance of construction permits. A split rail fence or other approved barrier and signage will be also be required to be permanently installed along the wetland and stream/creek buffer to denote the critical area and prevent intrusion into the wetland area and buffers. Mitigation Measures: • During site preparation and construction of improvements and residences, the applicant shall install silt fencing with brightly colored construction flags to indicate the boundaries of the wetland and stream/creek buffer.

DEPARTMENT ANALYSIS: 4. Staff Review Comments Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. Consistency With Short Plat Criteria Approval of a plat is based upon several factors. The following short plat criteria have been established to assist decision -makers in the review of the plat: a) Compliance with the Comprehensive Plan Designation The subject site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. The objective established by the RSF designation is to protect and enhance single- family neighborhoods. The proposal is consistent with the RSF designation in that it would provide for the future construction of single-family homes. The proposed plat is consistent with the following Comprehensive Plan objectives and policies for Residential Single Family Land Use, Community Design and the Environmental Elements: Land Use Element Objective LU-FF. Encourage re -investment and rehabilitation of existing housing, and development of new residential plats resulting in quality neighborhoods that. 1) Are planned at urban densities and implement Growth Management targets; 2) Promote expansion and use of public transportation; and 3) Make more efficient use of urban services and infrastructure. The project would add three new residential lots, plus retain the existing residence which would further Growth Management targets. Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per net acre in Residential Single Family neighborhoods. The proposed project for four lots would arrive at a net density of 5.4 dwelling units per net acre, after deduction of critical areas, which is within the allowable range of the R-8 zone. shpltrpt. doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 8 Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in -fill parcels of less than an acre (43,560 sq. ft.) in single-family designations. Allow a reduction in lot size to 4,500 square feet on parcels greater than an acre to create an incentive for aggregation of land. The site is greater than one acre and all lots would be greater than 4,500 sq. ft. Objective CD-K: Site plans for new development projects for all uses, including residential subdivisions, should include landscape plans. A conceptual landscape plan is included in the land use application submittal. Policy CD-45. Existing mature vegetation and distinctive trees should be retained and protected in developments. A Native Growth Protection Easement will be required to be recorded with the short plat to ensure the wetland and stream areas are protected from future impacts of development. The applicant is proposing to retain several trees within the rear yard area. Policy CD-53. Landscape plans for proposed development projects should include public entryways, street rights -of -way, storm -water detention ponds, and all common areas. A conceptual landscape plan provides for the required landscaping along the public right of ways. Policy CD-55. Maintenance programs should be required for landscaped areas in development projects, including entryways, street rights -of -way, storm -water retention/detention ponds, and common areas. The applicant will be required to maintain all common improvements as part creating a homeowners association or a maintenance agreement. Community Design Element Objective CD -A: The City's unique natural features, including land form, vegetation, lakeshore, river, creeks and streams, and wetlands should be protected and enhanced as opportunities arise. The wetland and stream would be protected within an open space/native growth protection area with the required 25 ft. buffer as stipulated in the ERC mitigation measures. Environmental Element Objective EN-C: Protect and enhance the City's rivers, major and minor creeks and intermittent stream courses. Mitigation measures are proposed on the project requiring the fencing and signage of the drainage course within the wetland area including a 25 feet stream buffer. Objective EN-D: Preserve and protect wetlands for overall system functioning. The Category 3 wetland would include a 25 ft. buffer and be fenced and signed as stipulated by the ERC mitigation measures. Policy EN-8. Achieve no overall net loss of the City's remaining wetlands base. The on -site wetland would not be disturbed or filled as part of this plat. It would remain as existing and protected via a 25 ft. buffer located within an open space/native growth protection easement. Policy EN-11. Water level fluctuations in wetlands used as part of the storm water detention systems should be similar to the fluctuations under natural conditions. The utilization, maintenance, and storage capacity provided in existing wetlands should be encouraged. Surface water from Lots 1 through 4 would be directed to the existing wetland; thus addressing this policy. b) Compliance with the Underlying Zoning Designation The 1.3 - acre site (gross area) consists of one parcel designated Residential — 8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development allows for the future construction of up to 4 dwelling units along with associated plat improvements. Density — The allowed density range in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per acre (du/ac). Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way and private easements from the gross acreage of the site. The property contains 12,304 sq. ft. of wetland to be deducted from the gross site area. After the deduction of 12,304 square feet from 44,680 gross square foot (44,680 sq. ft. site — 12,304 sq. ft. total deducted area = 32,376 net sq. ft. / 0.74 net acres), the proposal would arrive at a net density of 5.4 dwelling units per acre (4 units / 0.74 acres = 5.4 du/ac). The proposed short plat complies with density requirements for the R-8 zoning designation. shpltrpt. doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 9 Lot Dimensions — The minimum lot width requires 50 feet for interior lots and 60 feet for corner lots and a lot depth of 65 feet. The lot widths proposed would range from 51.17 to 158.5 feet and lot depths proposed would range from 103.11 to 220 feet. Lot sizes would be greater than the minimum of 4,500 square feet. All lots comply with the lot dimension requirements. Setbacks — The R-8 zone requires a minimum front and rear yard setbacks of 20 feet (15 feet front yard setback for primary structure and 20 feet for attached garages which access from the front yard street), side yard along a street of 15 feet and interior side yard setbacks of 5 feet. All lots appear to comply with the setback requirements and would be verified at the time of individual building permit review. Building Standards — The R-8 zone permits one single-family residential structure per lot. Each of the proposed lots would support the construction of one detached residential unit. Accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet in size. Building height in the R-8 zone is limited to 2 stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is limited to 35% of the lot area or 2,500 square feet, whichever is greater, for lots over 5,000 square feet in size, and 50% for lots less than 5,000 square feet in size. The proposal's compliance with each of these building standards will be verified prior to the issuance of building permits for each individual structure. c) Community Assets The R-8 zone requires off -site landscaping abutting non -arterial public streets (NE 24th St., High and Jones Avenues NE). A five-foot wide irrigated or drought resistant landscape strip must be installed and if there is additional undeveloped right-of-way in excess of five feet, this additional width must be landscaped. Additionally, a minimum of two trees of a City approved species with a minimum caliper of 1 '/2 inches per tree must be planted in the front yard or planting strip of every lot prior to final building inspection. The proposal's compliance with this standard would be verified prior to the final building inspection. Several of the general landscape requirements include: on -site landscaping is generally required along all street frontages, except for walkways and driveways; when rear or side yards are along property lines abutting a street, a minimum of five (5) feet of planting area in the public right-of- way; use of drought resistant plant materials. According to RMC 4-4-070, landscaping is required for this subdivision. A conceptual landscaping plan was included in the submittal of the Short Plat. The conceptual plan shall be revised to extend the five-foot wide irrigated or drought resistant landscape strip along High Avenue NE as required by code. Prior to the issuance of building permits, a detailed landscape plan must be submitted and approved. To ensure maintenance of the required landscaping staff recommends the following condition of short plat approval: a maintenance agreement shall be created concurrently with the recording of the short plat in order to establish maintenance responsibilities for all shared improvements, including landscaping and irrigation system. The agreement shall be placed on the face of the final short plat. d) Compliance with Subdivision Regulations Streets: No new public streets would be created as part of the proposed short plat. RMC section 4-7-150.F of the Subdivision Regulations requires the installation of half.street improvements, including curb, gutter, sidewalk, drainage, street signs, street lights and paving along the frontage of Jones Avenue NE, NE 24th Street and High Avenue NE pursuant to City of Renton Street Standards (RMC section 4-6-060) prior to recording of the short plat unless already in place or deferred or waived by the Board of Public Works. As the proposal would result in an increase in traffic trips to the City's street system, staff recommended as a Mitigation Measure of SEPA that the applicant pay the appropriate Traffic Mitigation Fee. The Traffic Mitigation Fee is calculated at a rate of $75.00 per additional generated trip. A Traffic Study may be required at the time of building permit submittal to determine the number of trips generated. The fee is payable prior to the issuance of a building permit. Blocks: No new blocks will be created as part of the proposed short plat. shpltrpt.doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page W Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. The lots are generally rectangular in shape except of the shared property line of Lots 2, 3 and 4 following the boundary of the on -site stream. Lots 1 and 2 are oriented to NE 24`h Street. The existing single-family residence is located on Lot 1, which meets setbacks, width and area as a corner lot. Lot 3 is a long narrow lot meeting minimum width requirement and oriented to High Avenue NE. Lot 4 is considered a corner lot on NE 24`h Street and Jones Avenue NE minimum width requirement. All lots meet and exceed the minimum lot areas however due to the native growth protection area easement (NGPA), the building area of Lots 2 and 4 are somewhat restricted. Lot 2 especially has a unique buildable area, which will require the applicant to customize the construction plan to fit the lot without impact to the NGPA. Each of the proposed lots satisfies the minimum lot area and dimension requirements of the R-8 zone. The plat plan does include setback lines for each lot showing potential building envelopes and when considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single-family homes. e) Reasonableness of Proposed Boundaries Access: Access shall be provided to Lots 1, 2 and 4 directly from NE 241h Street. Lots 1 and 4 shall be considered corner lots along High Avenue NE and Jones Avenue NE respectively. Lot 3 fronts directly on High Avenue NE, which is a dead end street. To meet Fire Department requirements for dead end streets exceeding 500 feet in length, a hammerhead turnaround shall be required along High Avenue NE meeting code specifications. This code requirement shall be meet prior to the approval of the construction plans, please reference Advisory Notes of this report. Topography: The site is rolling with slope range of 4 to 5 percent. The site is treed with a Category 3 wetland and a stream bisecting the site south to north. The developable portion of the site is vegetated primarily with trees and grass in addition to landscaping for the existing residence. The applicant is proposing to remove 10 trees outside of the native growth protection area easement. The geotechnical report submittal was waived unless determined necessary at the construction or building permit review. Please refer to the discussion under "Earth" in the environmental review section of this report for additional analysis. Staff recommends that a Native Growth Protection Easement (NGPE) be recorded over the protected wetland and stream prior to short plat recording. Relationship to Existing Uses: The subject site currently contains a 1,184 sq ft single-family residence, which is to remain on proposed Lot 1. The properties to the north, south and east of the subject site are designated Residential — 8 dwelling units per acre (R-8) on the City's zoning map. The parcels surrounding the site contain single-family residences. Across Jones Avenue NE to the east, is a parcel undergoing development of the 9-lot Bartell Short Plat. To the west of the site is Interstate-405 right-of-way. The proposal is consistent with the intent of the both the Comprehensive Plan and Zoning Code and would not be out of character with the existing or recent development in the area. Environmental Considerations: The City's Critical Areas maps depict the presence of wetlands and a stream on site. The wetland on the site meets the criteria as a forested Category 3 wetland according to Wetland Delineation report prepared by The Riley Group, Inc. dated January 15, 2005. Additionally, on -site stream bisects the site. This land use application is vested prior to the Critical Areas ordinance adopted in May of 2005. Please refer to the discussion under "Wetland/Stream" in the environmental review section of this report for additional analysis. In order to ensure protection of the wetland, stream and the buffer, staff recommends that a Native Growth Protection Easement (NGPE) be recorded over the protected wetland and stream prior to short plat recording. t) Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide Code shpltrpt.doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 21, 2005 PROJECT LUA-05-050, SHPL-A, ECF Page 11 required improvements and fees. As part of SEPA, staff recommended a mitigation measure for a Fire Mitigation Fee in order to mitigate the project's potential impacts to emergency services. Schools: The site is located within the boundaries of the Renton School District. Renton School District No. 403 has indicated that Kennydale Elementary School, McKnight Middle School and Hazen High School can accommodate the increased student enrollment that may result from the development of the proposed project, estimated at 1.76 or 2 (0.44 x 4 = 1.76 or 2) students. The school district has indicated that these schools would be able to support the additional students generated by the proposal. Storm Water. A drainage ditch exists on the south side of NE 24th Street. No improved drainage facilities front this site. The applicant submitted a preliminary drainage report with the short plat application addressing requirements for detention and water quality design per the 1990 King County Surface Water Design Manual. The project site drains to South Kennydale Creek basin. Surface Water System Development Charge will be assessed at a rate of $715.00 per single- family dwelling with credit giving for the existing structure. Payment of these fees shall be required prior to issuance of the utility construction permit. Water and Sanitary Sewer Utilities: There is an existing 8-inch water main in Jones Avenue NE and a 6-inch steel dead end water main in NE 24th Street. An 8-inch water main extension shall be required in NE 24th Street and High Avenue NE. Available fire flow at the project site is 700 gpm. Static pressure is 80 psi. The project is located in the 435-water pressure zone and the Aquifer Protection Zone 2. The fire flow requirement for the proposed development is 1,000 gpm; fire hydrants are required within 300 feet of all structures. The Water System Development Charge will be assessed at the rate of $1,525.00 per single-family dwelling with credit giving for the existing structure. Payment of these fees shall be required prior to issuance of the utility construction permit. There is an existing 8-inch sewer main in Jones Avenue NE and a portion of NE 24th Street. The extension of the sewer is required in NE 24th and High Avenue NE. The site is subject to NE 20th & Jones Special Assessment District (SAD) based on square footage and the West Kennydale Special Assessment District (SAD) based on number of lots. Payment of these fees shall be required prior to issuance of the utility construction permit. The Sanity Sewer System Development Charges will be assessed at a rate of $900.00 per single-family dwelling. No credit is given for the existing dwelling, as it is on septic and will be required to connect to the new sewer main prior to recording of the short plat. G.

SECTROWWRANnE Printed by Print g Mail Svcs, City of Renton REPORT NO. 1 OF FOUR REHABILITATION OF CITY OF RENTON WELL NO. 5 February 19, 1987 City Project CAG-070-86 Prepared by CH2M HILL NORTHWEST, INC. Bellevue, Washington S22077.A0 se6105/030/1 REPORT NO. 1 OF FOUR REHABILITATION OF CITY OF RENTON WELL NO. 5 February 19, 1987 (City Project CAG-070-86) INTRODUCTION Under an agreement for engineering services dated Novem- ber 25, 1986, between the City of Renton and CA2M HILL NORTHWEST, INC., the consultant undertook to perform seven basic tasks, which are all enumerated in Exhibit A to the agreement. This first project report addresses Task 1, Sub - tasks "a" through "d," Well Rehabilitation Study. Well No. 5 has been previously evaluated by R. W. Beck and Associates and their subconsultant, Converse Consultants. R. W. Beck submitted a report to the City dated November 1983 (Task 1--Summary) with a November 16, 1983, report by Converse Consultants as an appendix. A second undated re- port by R. W. Beck (Task 2--Summary Report) with a March 30, 1984, report by Converse Consultants as an appendix was also submitted to the City. Well No. 5 consists of an existing production casing and screen assembly from which the pumping equipment has been removed. The well was taken out of service in the 1960's because it pumped sand and the water contained unacceptable levels of H S and manganese. The goal is to rehabilitate the well to2deliver a minimum of 1,000 gallons per minute (gpm) of water with a quality that, after cost-effective treatment and/or blending with water derived from other city sources, will be suitable for delivery to water customers. The City has provided copies of the Beck reports and field survey data. It is agreed in the engineering contract that CH2M HILL can rely upon the accuracy and adequacy of the items provided to the consultant. A well inspection video tape also has been made available. As -constructed details of the well are shown in Converse Consultant's Drawing No. 1 included as an appendix to this report. In the course of our work we have reviewed the Beck reports, viewed the video tape, and held telephone conversations with local well drillers to discuss possible rehabilitation methods and order -of -magnitude costs. Three rehabilitation alternatives have been developed. We have been directed by the City that the alternative of drilling a completely new well is not to be considered. The following sections dis- cuss the alternatives. se6105/024/1 REHABILITATION ALTERNATIVES WELL REDEVELOPMENT We recommend that the well be redeveloped. This is strongly favored over other alternatives because the risk of damaging the well is very low. There also are no available data to confirm that an intensive development program has ever been attempted. Development procedures should include surging or hydraulic jetting, and chemical treatment.

They do not include engineering, administration, or other charges. The well development work would be primarily to reduce the sand content to acceptable levels. It would not include test pumping to determine the reliable capacity of the well. If well development fails to reduce sand content to accept- able levels, then structural changes to the well must be considered. REMOVAL OF EXISTING SCREEN AND RISER AND REDRILLING LOWER SECTION OF WELL Removing the existing, apparently improperly sized screen sections and/or sand pack and replacing them with more appropriate ones is an excellent rehabilitation alternative if it can be achieved. Removal of the 12-inch screen and riser could be attempted by pulling with a pipe smaller than 12 inches in diameter, sand locked inside the 12-inch screen assembly. Angular sand particles placed in the screen assembly form the struc- tural connection between the two pipes. A rubber packer or strips of burlap attached to the lower end of the pulling pipe holds the sand in place. Two or three slots are cut near the end of the pulling pipe so that the sand joint can be loosened by backwashing if the attempt is not successful. After removing the existing screens, the well bore below the se6105/024/2 20-inch production casing would be redrilled, geophysically logged, and properly sized screens and gravel pack (if re- quired) installed. There are two advantages to this method: (1) if successful, the chances of constructing a sand -free well of the desired yield are good; (2) the cost of an unsuccessful attempt is relatively low (approximately $6,500). There is a risk, however, that if the 12-inch screen assembly begins to move it could become lodged at a higher elevation. If this occurs, the well could be damaged beyond repair.

W. Beck/Converse Con- sultants. Converse Drawing No. 4 is attached as an appendix to this report. We agree that this is a legitimate alterna- tive. The screen and sand pack should be sized only after obtaining a sample of the sand entering the well bore. This se6105/024/3 sample would be available if the well redevelopment alterna- tive was attempted first. If the well redevelopment alter- native is not considered, then the well should be pumped to obtain a sand sample for grain size analysis. Every effort to redevelop the lower screened section should be made prior to installation of the 8-inch screen assembly because it reportedly contributes 55 percent of the well yield (R. W. Beck/Converse). Results presented in the pre- vious investigations indicate that the fine sand bed from 359 to 365 feet below land surface (reported) is a likely source of sand for the lower screen located between 366 and 376 feet below surface. Converse Consultants report the lower 5 feet of the deeper screen is also plugged and could not be developed. The 1984 Converse report contains (pages 10 through 14) a discussion of the factors to be considered and the risks to be assessed in installing a new 8-inch screen within the existing 12-inch screen. Their discussion should be re- viewed by the City before this alternative is attempted.

The possibility of a reduction in each by more continuous pumping is men- tioned in the R. W. Beck Task 1 report. Further review of the well water under actual pumping conditions was recom- mended by Beck. The Task 2 report on pages 2 through 10 contains a detailed discussion of water quality, other than sand content, and possible treatment methods. This section should be reviewed by the City prior to selection of treat- ment alternatives. se6105/024/4 No further water samples have been taken since those of February 1984 which are the basis of the above -mentioned discussion. Under these circumstances we are unable to make treatment recommendations and suggest that this element of work be postponed until the well is rehabilitated and tested. At that time more water samples can be obtained for examination. SUMMARY This report describes rehabilitation alternatives to reduce the sand content of water produced from Well No. 5. The dilemma faced in well rehabilitation design is the uncer- tainty of the exact elevations and grain sizes of geologic materials recorded on the well log. This problem is not uncommon in water well construction and is caused by mixing of materials downhole and uncertainty of elevation datum. There is no guarantee that the the alternatives presented will lower the sand content of the discharge water to acceptable levels and/or achieve the minimum desired pumping rate of 1,000 gpm. The first step of the rehabilitation effort should be an earnest attempt at removing sand from the formation by surging or hydraulic jetting and chemical treatment. If development fails to lower the sand produc- tion to acceptable levels, either the existing 12-inch screen and riser assembly must be removed and replaced or a new 8-inch screen and riser assembly must be installed inside the existing 12-inch assembly. The relative merits of these alternatives and their order -of -magnitude costs are summarized below. Alternatives (a) Redevelopment (b) Remove existing screen and install 12-inch screen and riser (c) Eight -inch liner screen and riser Chances of Successfully Completing Alternative High Moderate High Chances of Lowering Sand Content and Maintaining Yield of 1,000 gpm Moderate High (if successful) Moderate Chances of Damaging Approximate Cost Well ($) Very Low 12,000 Moderate (unsuccessful) 6,500 (successful) 28,250 Low 15,000 Note: Costs are order -of -magnitude and do not include engineering, administration, or other charges. se6105/024/5 RECOMMENDATIONS We recommend that the well be redeveloped (Alternative 1). If this is unsuccessful, then the existing 12-inch screen and riser pipe should be pulled and a new 12-inch screen assembly installed (Alternative 2). We recommend Alterna- tive 2 because the moderate risk of failure of Alternative 2 is offset by the higher probability of successfully reducing sand and maintaining yield. se6105/024/6 O 9513 w4f � :e PURCHASE ORD. .40. +; SERVICES (OR SUBCONSULTANT) PROJECT NO.

RENTON WELL 45A Kn19 Ulf CH2M CH2M HILL ::HILL CONTRACTORS, SUBCONTRACTORS, VENDORS AND SUPPLIERS EQUAL OPPORTUNITY ADDENDUM Vendor acknowledges that for all contracts and/or purchase orders issued or entered into with CH2M HILL, in favor of the Vendor, this supplement, when applicable conditions prevail, will automatically be a part of and an attachment to CH2M HILL Purchase Order Form Number 119: therefore, Vendor agrees to the following provisions: EQUAL OPPORTUNITY CLAUSE Vendor shall be bound by and agrees to the following provisions as contained in Section 202 of Executive Order 11246 to wit: 1. The Vendor will not discriminate against any employee or application for employment because of race, color, religion, sex, or national origin. The Vendor will take affirmative action to ensure that applicants are employed, and that employees are treated during employment, without regard to their race, color, religion, sex, or national origin. Such action shall include, but not be limited to the following; employment, upgrading, demotion or transfer, recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. The Vendor agrees to post in conspicuous places, available to employees and applicants foremployment, notices setting forth the provisions of this nondiscrimination clause. 2. The Vendor will, in all solicitations or advertisements for employees placed by or on behalf of the Vendor, state that all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, or national origin. 3. The Vendor will send to each labor union or representative of workers with which he has a collective bargaining agreement or other contract or understanding, a notice advising the labor union or workers' representative of the Vendor's commitments under Section 202 of Executive Order 11246 of September 24, 1965. and shall post copies of the notice in conspicuous places available to employees and applicants for employment. 4. The Vendor will comply with all provisions of Executive Order 11246 of September 24,1965, and of the rules, regulations, and relevant orders of the Secretary of Labor. 5. The Vendor will furnish all information and reports required by Executive Order 11246 of September 24, 1965. and by the rules, regulations, and orders of the Secretary of Labor, or pursuant thereto, and will permit access to his books, records, and accounts by the Secretary of Labor for purpose of investigation to ascertain compliance with such rules, regulations, and orders. 6. In the event of the Vendor's noncompliance with the nondiscrimination clauses of this contractor with any of such rules, regulations, or orders, this Purchase Order/Contract maybe cancelled, terminated or suspended in whole or in part and the Vendor maybe declared ineligible for further Government contracts in accordance with procedures authorized in Executive Order 11246 of September 24, 1965, and such other sanctions maybe imposed and remedies invoked as provided in Executive Order 11246 of September 24, 1965, or by rule. regulation, or order of the Secretary of Labor, or as otherwise provided by law. 7. The Vendor will include the provisions of paragraphs t 1 1 through 171 in every Subcontract or Purchase Order unless exempted by rules, regulations or orders of the Secretary of Labor issued pursuant to Section 204 of Executive Order 11246 of September 24, 1965, so that such provisions will be binding upon each Subcontractor or Vendor. The Vendor will take such action with respect to any Subcontract or Purchase Order as the Secretary of Labor may direct as a means of enforcing such provisions including sanctions for noncompliance. Provided, however, that in the event the Vendor becomes involved in, or is threatened with, litigation with a Subcontractor or Vendor as a result of such direction by the Secretary of Labor, the Vendor may request the United States to enter into such litigation to protect the interests of the United States. AFFIRMATIVE ACTION COMPLIANCE PLAN The Vendor further agrees and certifies that if the value of any contract or purchase order is $50,000 or more and the Vendor has 50 or more employees the Vendor will, if so required, develop and maintain a written Affirmative Action Compliance Program for each of its establishments as required by Title 41, Code of Federal Regulations, Section 60-2. CERTIFICATION OF NONSEGREGATED FACILITIES Vendor certifies that he does not and will not maintain or provide for his employees any segregated facilities at any of his establishments, and that he does not and will not permit his employees to perform their services at any location, under his control, where segregated facilities are maintained. The phrase "segregated facilities" includes facilities which are in fact segregated on a basis of race, color, creed, or national origin because of explicit directive or by habit, local custom, or otherwise. Vendor agrees that he will obtain identical certifications from proposed subcontractors prior to the award of subcontracts exceeding $10,000 which are not exempt from the provisions of the Equal Employment Opportunity Clause. EMPLOYER INFORMATION REPORT (EEO-1, STANDARD FORM 100) The Vendor further agrees and certifies that if the value of any contract or purchase is $50,000 or more and the Vendor has 50 or more employees, the Vendor will file a complete and accurate report on Standard Form 100 , EEO-1 i with the appropriate Federal agency within thirty 130 1 days of the date of contract award, i unless such a report has been filed within the twelve t 121 month period preceding the date of the contract award j and otherwise comply and file such other compliance reports as may be required under regulations adopted thereunder. (cont. on reverse side) FORM 119A EMPLOYMENT OF VETERANS 1. As provided in Executive Order 11701 t 41 CFR 50-250 1 the Vendor agrees that all employment openings of the Vendor which exist at the time of execution of this contract and those which occur during the performance of this contract, including those not generated by the contract and including those occuring at an establishment of the Vendor other than the one wherein the contract is being performed but excluding those of independently operated corporate affiliates, shall, to the maximum extent feasible, be offered for listing at an appropriate local office of the Federal -State Employment Service system wherein the opening occurs and to provide such periodic reports to such local office regarding employment openings and hires as maybe required: Provided, that this provision shall not apply to openings which the Vendor fills from within the Vendor's organization or are filled pursuant to a customary and traditional employer - union hiring arrangement and that the listing of employment openings shall involve only the normal obligations which attach to the placing of job orders. 2. The Vendor agrees further to place the above provision in any subcontract directly under this contract. 3. As provided in Section 2012 of the Vietnam Veterans Readjustment Act of 1974, with respect to all Contracts in the amount of $10,000 or more, the Vendor shall take affirmative action to employ and advance in employment qualified disabled veterans and veterans of the Vietnam era. EMPLOYMENT OF HANDICAPPED Vendor shall be bound by and agrees to the provisions of Section 503 of the Rehabilitation Act of 1973, and all regulations, rules, and orders promulated thereunder, to wit: 1. The Vendor will not discriminate against any employee or applicant for employment because of physical or mental handicap in regard to any position for which the employee or applicant is qualified. The Vendor a sees to take affirmative action to employ, advance in employment and otherwise treat qualified handicapped individuals without discrimination based upon their physical or mental handicap in all employment practices such as the following; employment, upgrading, demotion or transfer, recruitment or recruitment advertising; layoff or termination, rates of pay or other forms of compensation, and selection for training, including apprenticeship. 2. The Vendor agrees, that if a handicapped individual files a complaint with the Vendor that he is not complying with the requirements of the Act, he will 1 1 1 investigate the complaint and take appropriate action consistent with the requirements of 20 CFR 741.29 and 21 maintain on file for three 131 years the record regarding the complaint and the actions taken. 3. The Vendor agrees that, if a handicapped individual files a complaint with the Department of Labor that he has not complied with the requirements of the Act 1 1) he will cooperate with the Department in its investigation of the complaint, and 121 he will provide all pertinent information regarding his employment practices with respect to the handicapped. 4. The Vendor agrees to comply with rules and regulations of the Secretary of Labor in 20 CFR Ch. VI, Part 741. 5. In the event of the Vendor's noncompliance with the requirements of this clause, the contract may be terminated or suspended in whole or in part. MINORITY BUSINESS ENTERPRISE (Executive Order 11625) 1. It is the policy of the Government that minority business enterprises shall have the maximum practicable opportunity to participate in the performance of Government contracts. 2. The Vendor agrees to use his best efforts to carry out this policy in the award of his subcontracts to the fullest extent consistent with the efficient performance of the contract. As used in this contract, the term "Minority Business Enterprise" means a business, at least 50 percent of which is owned by minority group members or, in the case of publicly owned business, at least 51 percent of the stock of which is owned by minority group members. For the purposes of this definition, minority group members are Negroes. Spanish-speaking American persons, American -Orientals, American -Indians, American -Eskimos, and the American Aleuts. Vendors may rely on written representations by subcontractors regarding their status as minority business enterprises in lieu of an independent investigation. ':.E_-1V RFD PUBLIC jl-;S ryEPT.

IVERS HENRY T. IVERS (1902-1074) EMMETT O. LENIHAN (IB94-1980 The undersigned is the attorney on behalf of Quendall Terminals, which is presently under consideration for Superfund listing as a hazardous waste site in the City of Renton. The materials located at Quendall Terminals are, in fact, less harmful than materials located at Gas Works Park in the City of Seattle. The nomination of Quendall Terminals to Superfund classification has occurred because of its proximity with Renton Well No. 5. Well No. 5 was terminated from use because of high mineral content which gave rise to customer dissatisfaction in the early 60's. It is our understanding and belief that in order to rehabilitate Well No. 5 for the Renton Water System would require development costs and treatment costs of a substantial amount of money. Alternatively, additional well sites could be located in the North end of the City for approximately the same cost outside of the three-mile zone. The Environmental Protection Agency evaluation of Quendall Ter- minals site is based upon the status of the area at the date of scoring. Quendall Terminals was scored in the summer of 1984. At that point in time, Well No. 5 was totally dormant, and in my understanding, not then determined to be reused. Therefore, we requested that the City of Renton advise the En- vironmental Protection Agency of the following facts: 1. That the City of Renton terminated Well No. 5 from use in the earlier 1960's (its last day of operation) and the shutdown included dismantling procedures to make it safe. Renton City Council June 20, 1985 Page 2 2. That as of the summer of 1984, there were no current established plans to rehabilitate and/or redevelop the well. With the foregoing letter, we intend to press our case with the City with the Environmental Protection Agency requesting a rescor- ing based on the "abandonment" of Well No. 5. This will document that it was not appropriate for consideration in the scoring process. This is an argument that we have already made in the comment period, but it needs -City support. We believe that it is important to Renton and to Quendall Ter- minals not to be classified as a hazardous waste site community. As a sincere reflection of our willingness to support this, we will contribute an approximate amount of $20,000 for exploration and drilling costs as to another well. This offer is contingent upon the City effectively communicating the fact that Well No. 5 is net now nor has it recently been a part of Renton Water System. With this result achieved, we believe our contribution can effectively achieve a superior water system for Renton. Sincerely, LENIHAN, McATEER, HANKEN & BORGERSEN JAMES C.

OF REG!NAL COUNSL. 1200 6 th Avenue EPA • REGION X Seattle, WA 98101 Re: Quendall Terminals Gentlemen: This letter is submitted on behalf of Quendall Terminals in regards to it's Renton site being nominated for inclusion on the National Priority List for hazardous waste sites. Quendall Terminals believe that the listing of its site at Renton, Washington on the National Priorities List for Superfund to be in error. Apparently only superficial confirmation of the Renton Municipal Supply System was relied upon. We believe that inappropriate (wrong) choices as to certain scoring decisions were made. We shall delineate the precise errors we find below. However, we would appreciate the opportunity to provide whatever information or additional details that you may want after you have reviewed this or during your review process. We believe the history and background of the site has been docu- mented in the information presently in your hands. The site was acquired by Reilly Tar & Chemical, our predecessors in interest, over sixty years ago. Quendall Terminals acquired the property in 1971. Prior to the acquisition, Reilly Tar & Chemical terminated operations in approximately 1968/69. No further deposit of hazardous waste materials has occurred. Quendall Terminals has made extensive site investigation and studies for rehabilitation of the site. Our investigation and evaluations have been shared with you. Much of the documentation utilized in your scoring is from information provided by us to you. We have reviewed the Hazardous Ranking Score (HRS) for Quendall Terminals. We take no exception with the evaluation with the air route analysis since it was found to be not applicable to conditions on the site. We have a single comment as to the surface water evaluation. Our comment relates to the evaluation of toxicity and persistence which we will address in the ground water route comments. The scoring as , U.S. Environmental Protection Agency L December 13, 1984 Page 2 to this section should be the same as scored in the ground water route for the reasons we will give there. This brings us to ground water route worksheet. We agree that there is an observed release. This brings into play sections 4 and 5 for evaluation. In our opinion we believe that the follow- ing portions were inappropriately scored. 1. 4-Toxicity/Persistence 2. 5-Targets-Ground Water Use 3. 5-Targets-Distance To Nearest Well/Population Served We will discuss each item in turn. TOXICITY/PERSISTENCE The choice utilized in the HRS was as to Toxicity/Persistence element of waste character Penta-chlorophenol. It has a toxicity level of 3 and a persistency level of 3. This results in an HRS score of 18. However in the sampling of the entire site this compound was located in a one location at a quantity of 86 UGL which represents a very minute quantity. Under CERCLA §102 it must meet a reportable quantity. There are no standards establishing that we have found establishing this quantity as reportable. This level of concentration is too small, too insignificant and can not be justified as the substance of concern for purposes of determin- ing waste characteristics in a 20 acre parcel.

TARGET -WELL AND POPULATION SERVED There is a statement that there are shallow domestic wells supply- ing water in the hills east of the site. By virtue of the eleva- tions of the hills east of the site, any shallow well would have to be located in a different aquifer than the aquifer located on the subject property. We contend and assert that neither of these well categories, shallow private wells or the public Class I Well, draw upon the aquifer of concern. The Class 1 well is stated as being used for peak summer demand only. This is totally false. See R.W. Beck, Engineers Well No. 5 Report, 83-5194. The City of Renton verifies that the well referred to has been out of service for twenty years and is not at the present time connected into the city water system whatsoever. It is being considered as additional site. However, the City of Renton is aware of the contamination at Port Quendall and has relied upon engineering studies that this problem would not be a matter of concern. See R.W. Beck Report 83-5194. However, no funding currently exists and the plans are so indefinite and speculative to invalidate consideration of this well. Since we believe that the private wells .are not in the aquifer of concern and since the Class 1 well referred to is not even in operation and has not been for many years, we believe that the appropriate value be placed at 0. But even should the private wells be considered, the population served should be measured by a popu- lation of only 100. This would result in a scoring of 8. There- fore, the HRS scoring under ground water route analysis for "Target" scores would then be 14 which is eight tiraes the multi- plier of one plus two times the multiplier of 3. This would result in a scoring from the following factors: 45 X 13 X 14 with a resultant score of 8,190. 8,190 divided by 57,330 equals .1428 which multiplied by 100 would give a score of 14.28. This would be the score =or the ground water route worksheet. The surface water worksheet would also ''^e similarly adjusted to reflect the waste characteristic :core of 13.

WELL PRODUCTION AND AQUIFER TESTS PUMP TESTS The purpose of the pump tests conducted on Renton Well NO. 5 upper and evaluate the relative contributions of water and sand by the lower screened sections of the well (see "As -Constructed Dtails."nDraw- ing 1).

After 30 minutes of pumping it was evident that the drawdoWMi , the well had increased over threefold in contrast to Test No. 1. After no measurable sand was observed, the pumping rate was stepped up to 600 gpm for about 140 minutes and finally to 800 9Pm for the remainder of the test. Slight fluctuations in water levels were ob which suggested - served during testing at 600 and 800 gpm , that some groundwater was moving up through the gravel pack on the outside of the inner casing, contributing to the well yield.._ WELL HYDRAULICS The hydraulic characteristics of Well No. 5 were evaluated from the step-drawdown test by the method of Cooper and Jacob (1946), as de- scribed in Kruseman and DeRidder (1970, pp. 138-140). This procedure consists of plotting and analyzing drawdowns in the .tusual imes (see. that standard references such as Johnson UOP, 1972) except discharge re mathematically adjusted for all observations made after pump is increased. Both the original and adjusted drawdown data are plotted on Drawings 2 and 3 for the first and second tests, respectively. Cal- culated specific capacities and apparent transmi ssi vi ties are shown each discharge increment. Effect of Aquifer Properties on Well Performance The drawdown characteristics observed in the first pump test (Drawing 2) suggest that the aquifer utilized by the well could terminate abetween e we n 1/4 and 3/4 mile away in some direction. This is suggested by an decrease in apparent transmissivity* after about 115 minutes of pumping at 1,100 gpm or 150 minutes at 1,280 gpm. Some of the water -bearing beds appear to be even more limited in extent, as suggested by a de- crease in apparent transmissivity about 20 minutes into pumping at 600 water- abilit the measur ng *Transmissivity is a ivalente tof thee averaget aquifertipermeabilityo times aquifer.

An effective transmissivity of 30,000 gpd/foot should allow ained pumping at 1,300 gpm or higher. Effect of Well Construction on performance During the first test, with both screen sections open to the well bore, specific capacities* decreased slightly with increasing pump rates, from 70 gpm/foot at 380 gpm to 53 gpm/foot at 1,280 gpm. The first reduction in specific capacity, between the 380 to 600 gpm pumping rates, is prob- ably related to aquifer properties. Some of the sand and that gravel produce in the aquifer zone are probably discontinuous, suchs .boundary water at a reduced rate after a short period of pumpin g effect" was noticed after about 25 minutes at 600 gpm or This minutes at 850 gpm, as discussed in the previous subsection. between 850 and 1,100 gpm, The second reduction in specific capacity, related to the onset probably represents a decrease in well efficiency of the turbulent flow across the well screen.

At fIowlrates above 600 gpm, measurable sand concentrations were ob- sts. In general, the water discharge be - served -during both pumping te came sand -free or produced less than 1 to 2 ppm by volume of sand after 10 to 15, minutes of pumping. At no time did the water come sand -free at pumping rates above 800 gpm- Sand Sand concentrations ranged from 75 to under 1 ppm y volume when both screens were being pumped simultaneously (Test No. 1). At the end of each step during Test No. 1, sand concentrations diminished from a trace at 600 gpm to 5 ppm at 1,100 gpm. Sand production during testing of the upper screen (Test No. 2) at the end of 30 minutes of pumping ranged from a trace to 1 ppm by volume. Based on these results, there appears to be a two- to threefold increase in sand production when pumping from both screens at 600 gpm or greater in comparison to the upper screen by itself. Although sanding rates are less when pumping the upper screen alone, it is our opinion that corrective measures are advisable to elim- inate sand production from both screens. Sand production from the upper screen could possibly be eliminated by surging and redeveloping known until screen; however, the success of this procedure would not be after redevelopment has been attempted. A groundwater investigation report of the Port Quendall property, pre- pared in 1983 by Woodward -Clyde Consultants, was reviewed imat lyat the request of the City of Renton.

Convem ConsulhnW kc. The. 1983 report suggests the alluvial deposits are underlain by a rela- tively this k clay unit that is widespread throughout King County. They further state that it appears the clay unit acts as an aquitard, in- hibiting downward movement of water from the younger alluvial sediments. A published geologic map of the area shows that the side slopes of May Creek valley are mantled by glacial till, a relatively impermeable de- posit consisting of cobbles to clay -size materials. This suggests that the lateral migration of potential contaminants from the Port Quendall site into adjacent aquifers is unlikely, although further study would be needed to confirm this conclusion. However, based on the subsurface conditions at the Port Quendall site as indicated by Woodward-Clyde's report and the relatively steep potential gradient between both sites (note groundwater flows from higher to lower elevations), it does not appear that the proposed pumping of Well I5 will induce movement of groundwater from the Port Quendall property into the glacial aquifer penetrated by Well #5. RECOOMNOATIONS FOR WELL REHABILITATION Based on evaluation of geologic conditions and pump test results, it appears that Well No. 5 penetrates a highly productive aquifer at a depth of about 325 to 375 feet. The aquifer is well stratified, ranging from layers of fine sand to layers of coarse sand and gravel. Because of the gradation characteristics, thicknesses, and amount of interbed- ` ding, the aquifer is quite complex and variable at the well site. Pump test results indicate both screened sections contribute substantially to the well capacity. The variability of aquifer deposits, in combination with the coarse, well -graded gravel pack, is the primary cause of sand production through both screens, but particularly, the lower one. sea 1h - - ._ Clad sti. -. _._ ��_ . _: ...__ :. .• `__ 14•,e ,lilacV. coo • '.

Beck and Associates Oplechnical Engineering 0,1 Converse Consultants and APPIl*dSelrrnces- 83-5194 Drawing NO 1 -3- 4PPENDIX A The City.- Of Renton Well No. 5 was drilled and completed by N.C. Jannsen Drilling Company in 1953. Records show the well was drilled to a depth of 388 feet_ and cased with 3/8-inch x 20-inch O.D. casing from original ground" surf ad to 287 feet. From 287 to 340 feet in depth, the hole was "under reamed" to 30 inches in diameter and below 340 feet the well was completed with an 18-inch diameter drill hole. A copy of the original as -constructed details of Well No. 5 is shown on Drawing 1. All meas- urements shown on Drawing 1 are referenced to original ground surface. Drawing 1 indicates that a 12-inch I.D. inner casing extends from 247 to 376 feet, with two separate sections of 12-inch Everdor Bronze Cook screen (0.100-inch slots) joined to the casing from 318 to 338 feet and 366 to 376 feet, respectively. The original driller's record indicates that a 12-inch casing extends from 376 to 388 feet below the lower screen which conflicts with the final detail shown on Drawing 1. It is likely that a casing does extend to the bottom of the drill hole but this could not be confirmed during our Task 1 investigation. Records also show that the bottom of the screen was plugged to tightly seal the bottom of screen. The means of plugging could not be determined, but several possibilities exist, including but not limited to: a concrete bottom, a threaded or welded plate attached to the screen or casing, and a lead or clay plug. The original bid proposal from N.C. Jannsen indi- cates their wells are generally completed with cemented bottoms but no reference to how Well No. 5 was completed could be found. The well was gravel -packed with a 1/4-inch minus washed fine gravel. The gravel pack extended from approximately 248 to 388 feet, enveloping the inner casing and screen. The gravel pack extended 40 feet into the 20-inch O.D. casing and 12 feet below the lower screen. Converse ConsuftnM. IM.
