The 48" reinforced concrete pipe (RCP) running down Garden Avenue N between N 8th Street and Lake Washington Boulevard is grossly inadequate for carrying this flow and the system must be upgraded. In order to have sufficient capacity to carry this flow, a parallel 66" RCP (or material with similar flow characteristics) is required. The length of system to be contributed by the Garden and Park Plaza (see Figure 1) projects was computed using the existing system capacity for allowable outfall and a 25 year design storm. The necessary volume was determined as 18,774 fts which corresponds to approximately 790 l.f. of 66" pipe. To maximize the early benefit, the pipe contributions should be started on the lower end of the system and worked upstream. In lieu of on -site detention, this contribution will be added to as further development continues in the lower portion of the North Renton Basin. That portion of the basin which lies east of SR 405 would remain as an on -site detention region with any drainage problems on this side being corrected by regional detention rather than by upgrading the I-405 crossings. Basin Characteristics The North Renton Basin contains approximately 773 acres consisting of two regions with vastly different characteristics. These regions are separated by I-405. The upper basin area to the east of I-405 is the Highlands region. The lower basin area west of I-405 is the Valley region. The Highlands region is roughly bordered by Sunset Boulevard on the north, NE 4th Street on the south, Monroe Avenue NE on the East, and I-405 on the west. This region slopes down to the west at approximately 5 percent. While development consists mainly of residential, there are some smaller areas covered with apartments, commercial sites, and schools. Soils characteristics vary anywhere between Type A to Type C (reference; Soils Survey King County Area Washington, United States Department of Agriculture Soils Conservation Service, Nov. 1973.) The Highlands region discharges into the Valley region through several culverts crossing under I-405. Flows are transported from the Highlands region through the Valley region out to Lake Washington. The Valley region is bordered by I-405 on the east, Burnett Avenue N on the west, N 4th Street on the south, and Lake Washington on the north. This region has flat slopes and is highly industrialized with a small percentage of residential. The soils category consists of Type C. There are two points of discharge (see Figure 2) from the Valley region. The majority of the flow is discharged through the 48" concrete pipe running north along Garden Avenue N from N 8th Street to Lake Washington Boulevard. From there it discharges through a series of other culverts and open ditches until it reaches Lake Washington. The second outfall is a 24" concrete line running from the end of N 7th Street out to the Cedar River. Due to the shallow slope, the capacity of this line is inadequate, even considering the maximum available head. For this reason, the two systems are interconnected such that the flow which does not flow down the 24" line will backflow into the 48" line running down Garden Avenue N. Page 2 of 5 Peak 25 Year Flow Analysis The North Renton Basin was broken up into 11 separate subbasins (see Figure 2) due to topography, existing storm systems, and critical flow control points. The control points were crossings of I-405 and major storm drainage intersection points where one system was joined by another. Due to time restrictions, it was decided that the peak 25 year flow analysis would be done on the SCS TR-55 Program. Existing and future "CN" values were developed using U.S.G.S. soils maps, aerial photographs, and February 1988 zoning maps (see Figure 3). The travel times and times of concentration were calculated using available information on existing storm systems and topographical information from 1968 City of Renton topographical maps. Running the CN value, time of concentration, and travel time through the TR-55 program for each of the 1 I subbasins, the peak 25 year flow at the outlet point of the intersection of Garden Avenue N and N 8th Street from the North Renton Basin was calculated to be 289.22 c.f.s. Upon further study of the flow control points, it was found that Areas 1, 2, and 3 flowed to a 21" CP with the maximum capacity of 30 c.f.s. The flows exceeded this volume starting at the 7.9 hour mark at which point the excess flow would take an alternate path to the outlet point.. The excess flow (that above 30 c.f.s.) was lagged by approximately 1/2 hour, which is the time determined for the flow to run down Sunset Blvd, cross I-405 through the 30" CMP and travel in a ditch along the west side of 1-405 to a point joining the original flow path. The resulting peak flow was calculated to be 202.0 c.f.s. When a similar adjustment was performed for area No. 6, the peak flow was found to be 199.1 c.f.s. Page 3 of 5 The peak flow which is required to flow down the Garden Avenu N storm line would be the computed peak flow subtracted by the capacity of the 24" CP outfall to the Cedar River. This will yield 186.9 c.f.s. as the necessary volume of flow which the system must eventually carry Existing Capacity The storm line running down Garden consists of approximately 2,375 IS. of 48" RCP with seven manholes in between. Calculating the capacity, using Manning's equation, under full head conditions (headwater at Roadway surface), a maximum flow of 93 c.f.s. will flow through. Through trial and error on the TR-55, a rainfall of 2.0 inches, corresponding to a 2 year storm, yields a peak flow down Garden Avenue N of 93.2 c.f.s. which is the approximate capacity of the system in question. For calculation of development contribution, the 2 year storm will be the allowable outlet criteria based on the existing systems capacity. Upgrade Line Size Based upon the computed capacity of the existing line down Garden Avenue N and the computed peak 25 year flow, using Manning's equation, it was determined that a 66" pipe with an "n" value of 0.012 is required to parallel the existing 48" RCP. A head of 5.3' is needed to push the 25 year flow through this parallel system of pipes which will discharge into the ponding area on the south side of Lake Washington Boulevard before crossing beneath the road via two 48" CP culverts. Contribution by Park and Garden Plaza On -site detention required for the Park Plaza and Garden Plaza projects was calculated using a 25 year storm with the release rate restricted to the capacity of the existing system (2 year storm). For Page 4 of 5 simplification purposes, all three sites were combined as one with an average CN and the longest Tc taken for the site. The combined sites resulted in an area of 10.4 acres, CN of 92, and the longest Tc being 16 min. Running the calculated numbers through the SCS TR-20 program, a predevelopment 2 year flow of 3.02 c.f.s. was computed. For post development conditions, the same Tc and a CN of 98 were assumed. Passing the post development flows through a simulated detention system (using a structure and reservoir card based on a 66" pipe with a single orifice and overflow at the top of the pipe), successive runs were performed increasing the length of the pipe until the maximum outflow of 3.02 c.f.s. was attained without encountering overflow conditions. The necessary volume to fit these conditions is 18,774 ft3 of detention. This corresponds to approximately 790 IS. of 66" pipe which is required, in lieu of on -site detention, to fulfill the requirements.

WATERMAINS Park Plaza Existing 16" watermain across the site must be relocated. New watermain must be realigned and operational before the 16" watermain is taken out of service for foundation construction at Park Plaza. MEMO July 21, 1987 Page 2 Rnth Citric Fire Marshall must assign fire flow demands first, then E&H provide fire flow computer analysis to determine watermains needed in City watermain system to provide fire flows. All streets reconstructed/widen must have new 12" minimum) size watermains: North 5th Street - Garden to Park; Park Avenue North - N. 5th to N. 8th; North 6th Street - Garden Ave. N. to Park and perhaps to West. STORM DRAINAGE Rnth Citric Provide storm drainage analysis of projects, and analyze down stream storm system on North 6th Street westerly to Cedar River. Provide 10/10 Year Storm Detention on site to control run off to predeveloped rates -012. Provide storm improvements down stream to allow no detention. All streets reconstructed/widened shall have new storm drains constructed to provide 25-year capacity on local drainage and 50-year on trunk capacity lines: North 5th Street - Park to Garden; Park Avenue North - N. 5th St. to N. 8th St.; North 6th Street - Garden to Park and perhaps to West. Other storm improvements may be required in area to prevent flooding of key intersections, buildings, fire access and rescue staging areas.

The following items were discussed with regard to the cleaning of the detention pond: 1. Pumps would be used to bypass the flows around the detention area and would be maintained 24 hours a day during the length of construction. 2. Straw hay bales would be placed around the outlet cage with a sump area dug to trap any silt in the pond resulting from a storm occurrence. 3. Following construction finish, the exposed areas in the pond will be seeded to reestablish vegetation. 4. Due to the location of the fence on the south side of the pond, the slope on that side was to be maintained at its present steepness in order to facilitate the necessary detention size. Following the meeting, I contacted Elmer regarding the effect on the volume of the 2:1 slope, on the south side of the pond. It was decided that the Contractor would be required to have the Consulting Engineer check into possible volume problems. Garth D.

All wastewater and contaminated storm water should be discharged to the sanitary sewer. This includes, but is not limited to, vehicle steam cleaning wastewater, equipment wash wastewater, etc. Metro's Industrial Waste Section can pro- vide information on the pre-treatment requirements. 2. All floor drains inside the vehicle repair shop shall go to pre-treatment. Discharge from the oil/water separator shall then go to the sanitary sewer. 3. No contaminated water shall be discharged to existing dry wells. 4. Catchbasins in areas subject to truck fueling and pos- sible spillage should be "type-2" catchbasins with turndown elbows. 5. Any spraying done for dust generated during construction should be done with water or a solution approved by the De- partment of Ecology (see attachment). It is the Department's position that no waste oil be utilized for dust control. If you have any questions, please call Ms. Gail Colburn of the Northwest Regional Office at (206) 867-7058.

This policy was developed in cooperation with the regional offices, solid and hazardous waste, air quality, and water quality programs. It is consistent with the 17 other states which have either bans or restrictions on used oil as a dust suppressant. In order to encourage recycling, used oil is not listed as hazardous waste by EPA or Ecology. But used oil typically contains high levels of heavy metals (especially lead and zinc) and can contain carcinogenic contaminants or PCBs. EPA currently claims no jurisdiction over used oil for dust suppression unless it is contaminated with hazardous waste. However, EPA does not require testing to determine hazardous waste content. With regard to concerns of the agricultural community, RCW 70.95.240 basically exempts people who accumulate their own solid waste from their own activities and apply it to their own land. This year has been shaping up to be the third drought year in a row. We are going to need consistent agency guidance in place this summer to he able to deal with used oil for dust control. '['his policy, along with the dust suppression alternatives which accompany it, will provide the necessary consistent guidance. Attachment cc: Rhonda Hunter c-�a�l 3 state of W ashir gto �n 1 k'I kill I I ICI11 (A t -mk )gy 0-1� POLICY TITLE: Used Oil Recycling Policy No. Recycling 1 Page 1 of 2 Eff. Date _ Director Appr. PURPOSE: To coordinate agency response to encourage used oil recycling instead of land disposal. Further to restrict the use of used oil for dust suppression since used oil often contains heavy metals and toxic contaminants. In Chapter 19.114 RCW, the Legislature has recognized that millions of gallons of used oil are generated each year in this state and that its improper disposal has an adverse effect upon the economy and the environment. Improper disposal of used oil is a significant source of water pollution, has a detrimental impact on the fisheries industry, and contributes toward the overall shortage of energy resources. In light of these harmful consequences, the Legislature declared that it is the policy of this state to collect and recycle used oil. The recycling of used oil required in Chapter 19.114 RCW will be taken into consideration when administering other laws and regulations, including, but not limited to, Chapter 173-303 WAC and Chapter 90.48 RCW. Under Chapter 90.48 RCW, it is unlawful for oil to enter the ground waters or surface waters of the state. According to an EPA study, roughly 99 percent of the oil applied to road surfaces leaves the road mostly in rain water runoff or by adhesion to windblown fugitive dust. Used oil carries its load of lead and heavy metals into the environment. POLICY: It is the policy of this agency to encourage and foster the collection and recycling of used oil statewide. Furthermore, this agency recommends against the application of used oil as a road oil or dust suppressant due to potential environmental contamination. DEFINITIONS: (1) "Used Oil" means any oil that has been refined from crude oil, used, and, as a result of such use, is contaminated by physical or chemical impurities as defined by the hazardous waste regulations for Washington State WAC 173-303-515. (2) "Recycle" means to prepare used oil for reuse as a petroleum product by refining, re -refining, reclaiming, reprocessing, or other means or to use used oil as a substitute for a petroleum product made from new oil, provided that the preparation or use is operationally safe, environmentally sound, and complies with all laws and rules. Policy 20. gpry1z �l iQ Page --of � (3) "Used oil dust suppressant" means any unre-refined used oil applied to reduce fugitive dust from road surfaces or any other land surface. PROCEDURES: RH167B4 Agency response to inquiries on appropriate use of used oil will encourage used oil recycling and will recommend against the use of used oil for road oiling or dust suppression. Printed on Recycled Paper The Problem Dust is more than just a nuisance on unpaved roads: ■ By obscuring the vision of drivers, dust clouds arc a traffic hazard. ■ Dust can carry several hundred feet, penetrating nearby homes and covering crops. Crop growth is stunted due to the shading effect and clogged plant pores. ■ In human health, dust is a common cause of allergies and hay fever and may be a conveyor of diseases. ■ Fine abrasive particles greatly increase wear on moving parts of a vehicle. ■ The loss of road binder, in the form of dust, represents a significant material and economic loss. The severity of a dust problem is determined primarily by the amount of speed of traffic on the unpaved road. The condition is aggravated by long dry spells, softer road aggregates that abrade under traffic to produce more dust, and initially excessive soil binder in the surface mix. Without binder material and adequate moisture, the coarser material will be thrown or washed away from the road surface. The road begins to ravel, rut, and washboard; deterioration accelerates until costly repairs are needed. The Solution Dust control using chemical or mechanical suppressants can be justified when: ■ paving is not feasible for lack of funds or limited use of the road, the cost of materials and application is low, ■ stage construction of the road is planned. The problem of dust from unpaved roads is a worldwide problem. Methods of treatment in the United States range from spraying roads with chemicals, chiefly chloride compounds and resinous adhesives, to utilizing geotextiles in road reconstruction. When chemicals are applied to the road surface to control dust: ■ the surface should first be crowned and shaped to final grade, to assure good drainage, ■ for all but resinous adhesives, the road must be prewcttcd with water (if natural moisture is lacking), to assist chemicals in penetrating the surface, ■ a heavy rainstorm shortly after application (within 36 hours) will wash away most of the chemical, and ■ more than one treatment a year with diluted forms is generally necessary. The Choices A number of organic and inorganic chemical mixes are available for use as dust palliatives; synthetic fabrics are also available for physically containing the road materials. The chart contrasts the attributes, limitations, typical applications, and sources of materials used to suppress road dust. No ranking is implied by their order on the chart. The selection of a particular dust sup- pressant will depend not only on its performance characteristics, but also on the type and volume of traffic, roadway condition, and product cost (material, freight, and application) to achieve the desired level of dust control. These criteria will vary significantly. Some successful cost -saving measures have been reported, for example, treating only a center strip of the roadway on less - traveled roads or spot -treating on a cost -share basis with roadside residents. Calcium chloride has been used to treat unpaved road surfaces since the last century. It not only retards evaporation from the road during the heat of the day, but because of its ability to attract moisture, actually recaptures lost moisture at night or under other favorable humidity, conditions. Other chlorides are widely used in the northwest, particularly for stabilizing the surfaces of haul roads. A mix of common salt and calcium chloride cuts the material cost appreciably, while controlling dust effectively. The adhesive and waterproofing character of bituminous materials is well known, but cost is usually prohibitive unless the treatment precedes some type of asphalt paving. Lignin derivatives are natural cements that bind the dust particles, aided by associated sugars which act as hydroscopic agents; they are also excellent dispersing agents for clays, meaning reduced water penetration during wet periods. Various hybrid products are emerging (for example, a bitumen-lignin dust control agent), which pose opportunities for cooperative test projects. N a S II I N f T O N S T A T E ,�rra�rrA� �;r ar F (.

CHEMICAL -Organic OJ� N .J �A �cl Qa MECHANICAL GC� a�o �0 Attributes ■ Poses no threat to the environment. ■ Normally, readily available. ■ Binds soils because of asphalt's adhesive proper - tics. ■ Serves to waterproof road. ■ May be adapted to suit wide range of soils, gravels, and traffic conditions. ■ Greatly increases dry strength of soil; under dry conditions, outperforms bituminous binders. ■ During rain, disperses clay which in turn swells and plugs pores, reducing water penetration. ■ Tends to remain slightly plastic, permitting reshaping and additional traffic compaction. ■ With addition of calcium carbonate slurry to counteract corrosive effects, solubility is reduced, thereby prolonging dust - laying capability. ■ Flexible, durable, water permeable, and highly resistant to soil chemicals. ■ Used as a separator, prevents intermixing of subgrade material and base course, thereby preserving drainage systems and load transfer capability. Structural section life is prolonged and maintenance costs reduced. ■ By preventing subgrade fines from "pumping" up into the aggregate, serves to control dust production. ■ Ammonium -base sulfides are superior to sugar -free calcium -base sulfides for aggregate binding. ■ Material cost comparable to that of inorganic chemicals. ■ In tension, reduces localized loads over a larger area of subgrade, thereby improving the support properties of the system. ■ Can reduce the amount of aggregate required in the initial design of unpaved structural sections. ■ If buried, can be expected to function indefinitely. Limitations ■ Evaporates readily, controlling dust generally for less than a day. ■ Under dry conditions, some may not maintain resilience; can form a crust and fragment under traIT ic loads. ■ Waste oil subject to state regulations for handling and disposing of hazardous substances. ■ Control depends on well - graded soil -aggregate mix, loosened to a depth of I to inches just prior to initial application; wearing surface silt and clay content needs to be 4 to 8 percent. ■ May cause corrosion of aluminum and its alloys. ■ Surface binding action may be reduced or completely destroyed by heavy rain, owing to solubility of solids content in water. ■ Becomes slippery when wet, brittle when dry. ■ High material cost, though installation cost is low. ■ Material degradation may result from exposure to ultraviolet rays (sunlight).

Housing Authority: Senior Community Services Committee Chairman Reed presented a recommendation Citizen Housing Bond regarding the proposed bond issue for senior housing: Issue 1. The City Council should support the request from the Housing Authority to place the issue on the general election ballot (November 8, 1988). 2. The proposal should include a commitment to provide 72 or more units of additional housing to Renton's elderly residents at a cost of $5.5 million. 3. Rather than proposing a specific site for the development prior to the election, the City and Housing Authority should jointly identify a site after a thorough public process and will review alternatives after bonds are approved. 4. The City administration and Housing Authority should negotiate a cooperative agreement that will identify the respective role and responsibilities of the two entities with respect to this project. 5. The cooperative agreement and the ordinance placing the issue before the voters should be referred to the Ways and Means Committee for review and presentation for Council action.

MOVED BY NELSON, SECONDED BY STREDICKE, - Parking Ticket COUNCIL CONCUR IN THE COMMITTEE REPORT. CARRIED. Rezone: E & H Transportation Committee Chairman Nelson presented a report regarding the Properties, R-016-87 extent to which E & H Developments was to be given credit for regional traffic improvements against its $1.1 million bond and the extent to which the neighborhood mitigation program had to be installed before occupancy of the buildings. The City Attorney prepared a letter to the Council addressing these two questions. He concluded that credit for six improvements should be given against the $1.1 million bond to the extent they are identified as regional traffic improvements from the study being prepared and then adopted by the City Council. The study evaluates alternative twenty-year development land use scenarios for the impact on the transportation system. The six possible traffic improvements for which credit could be given are as follows: September 12, 1988 Renton City Council Minutes Pape 260 1) Design a turn movement southbound on Park Avenue N. at N. 3rd to minimize conflicts in the left turning movement onto N. 3rd, including any change in the signal; nN ��' •hP Nor!h Renton Arterial Study to evaluate alternative 20-year development land use scenarios for the impact on the transportation system; 3) Reconstruct the intersection of Lake Washington Boulevard/Park/Garden to provide an additional eastbound lane on Park Drive from N. 10th to Garden Avenue N.; 4) Realign Garden Avenue N. at N. 8th to remove the existing dog leg; 5) Signalize the intersection of N. 6th and Garden Avenue N.; 6) Signalize the east and west legs of the Garden Avenue N. and N. 8th Street intersection. With respect to the extent to which the neighborhood mitigation program was to be installed before occupancy of the buildings, the conclusion was that occupancy is not contingent upon installation of the neighborhood mitigation program. However, the developer will have installed all of the neighborhood mitigation program that he has been authorized to install by the date of occupancy. There still may be an open question about traffic diverters, but that issue is outside the control of the developer. Once the developer has been directed to install an element of the neighborhood mitigation program, the Council conditions require the installation as rapidly as possible. It was recommended that the Council permit credit against the $1.1 million bond for regional traffic improvements recommended from the study detailed above when adopted by the City Council, but limited to the six transportation improvements listed in this report. It is further recommended that the occupancy permits for the buildings not be contingent upon installation of the neighborhood mitigation program, but that the developer install those improvements as rapidly as possible after being directed to proceed. MOVED BY NELSON, SECONDED BY TRIMM, COUNCIL CONCUR IN THE COMMITTEE REPORT.* Upon Council inquiry, City Attorney Warren explained that the conditions are extracts from those imposed by the Environmental Review Committee on the project. Upon Council approval and determination that an improvement is of regional transportation benefit, credit will be given against the $1.1 million bond provided by the developer dependent upon the percentage of regional benefit. Councilwoman Mathews clarified that the developer had agreed to complete 46 traffic improvements in addition to posting a $1.1 million bond. The six aforementioned traffic improvements, either part or whole, are eligible for credit if determined to be regional in nature by the Council. •MOTION CARRIED.

City of Renton Storm Water Utility North Renton Basin Interim Drainage Study to Address Development West of I-405 (Garden Plaza - Park Plaza) May 1988 Introduction An analysis (using SCS TR-55 Program) determining the expected flows at the intersection of Garden Avenue N and N 8th Street produced a peak flow of 223.39 c.f.s. based on a 25 year storm event. The 48" reinforced concrete pipe (RCP) running down Garden Avenue N between N 8th Street and Lake Washington Boulevard is grossly inadequate for carrying this flow and the system must be upgraded. In order to have sufficient capacity to carry this flow, a parallel 66" RCP (or material with similar flow characteristics) is required. The length of system to be contributed by the Garden and Park Plaza (see Figure 1) projects was computed using the existing system capacity for allowable outfall and a 25 year design storm. The necessary volume was determined as 18,774 fts which corresponds to approximately 790 l.f. of 66" pipe. To maximize the early benefit, the pipe contributions should be started on the lower end of the system and worked upstream. In lieu of on -site detention, this contribution will be added to as further development continues in the lower portion of the North Renton Basin. That portion of the basin which lies east of SR 405 would remain as an on -site detention region with any drainage problems on this side being corrected by regional detention rather than by upgrading the I-405 crossings. Basin Characteristics The North Renton Basin contains approximately 773 acres consisting of two regions with vastly different characteristics. These regions are separated by I-405. The upper basin area to the east of I-405 is the Highlands region. The lower basin area west of I-405 is the Valley region. The Highlands region is roughly bordered by Sunset Boulevard on the north, NE 4th Street on the south, Monroe Avenue NE on the East, and I-405 on the west. This region slopes down to the west at approximately 5 percent. While development consists mainly of residential, there are some smaller areas covered with apartments, commercial sites, and schools. Soils characteristics vary anywhere between Type A to Type C (reference; Soils Survey King County Area Washington, United States Department of Agriculture Soils Conservation Service, Nov. 1973.) The Highlands region discharges into the Valley region through several culverts crossing under I-405. Flows are transported from the Highlands region through the Valley region out to Lake Washington. The Valley region is bordered by I-405 on the east, Burnett Avenue N on the west, N 4th Street on the south, and Lake Washington on the north. This region has flat slopes and is highly industrialized with a small percentage of residential. The soils category consists of Type C. There are two points of discharge (see Figure 2) from the Valley region. The majority of the flow is discharged through the 48" concrete pipe running north along Garden Avenue N from N 8th Street to Lake Washington Boulevard. From there it discharges through a series of other culverts and open ditches until it reaches Lake Washington. The second outfall is a 24" concrete line running from the end of N 7th Street out to the Cedar River. Due to the shallow slope, the capacity of this line is inadequate, even considering the maximum available head. For this reason, the two systems are interconnected such that the flow which does not flow down the 24" line will backflow into the 48" line running down Garden Avenue N. Page 2 of 5 Peak 25 Year Flow Analysis The North Renton Basin was broken up into I separate subbasins (see Figure 2) due to topography, existing storm systems, and critical flow control points. The control points were crossings of I-405 and major storm drainage intersection points where one system was joined by another. Due to time restrictions, it was decided that the peak 25 year flow analysis would be done on the SCS TR-55 Program. Existing and future "CN" values were developed using U.S.G.S. soils maps, aerial photographs, and February 1988 zoning maps (see Figure 3). The travel times and times of concentration were calculated using available information on existing storm systems and topographical information from 1968 City of Renton topographical maps. Running the CN value, time of concentration, and travel time through the TR-55 program for each of the 11 subbasins, the peak 25 year flow at the outlet point of the intersection of Garden Avenue N and N 8th Street from the North Renton Basin was calculated to be 289.22 c.f.s. Upon further study of the flow control points, it was found that Areas 1, 2, and 3 flowed to a 21" CP with the maximum capacity of 30 c.f.s. The flows exceeded this volume starting at the 7.9 hour mark at which point the excess flow would take an alternate path to the outlet point.. The excess flow (that above 30 c.f.s.) was lagged by approximately 1 /2 hour, which is the time determined for the flow to run down Sunset Blvd, cross I-405 through the 30" CMP and travel in a ditch along the west side of I-405 to a point joining the original flow path. The resulting peak flow was calculated to be 202.0 c.f.s. When a similar adjustment was performed for area No. 6, the peak flow was found to be 199.1 c.f.s. Page 3 of 5 The peak flow which is required to flow down the Garden Avenu N storm line would be the computed peak flow subtracted by the capacity of the 24" CP outfall to the Cedar River. This will yield 186.9 c.f.s. as the necessary volume of flow which the system must eventually carry. Existing Capacity The storm line running down Garden consists of approximately 2,375 IS. of 48" RCP with seven manholes in between. Calculating the capacity, using Manning's equation, under full head conditions (headwater at Roadway surface), a maximum flow of 93 c.f.s. will flow through. Through trial and error on the TR-55, a rainfall of 2.0 inches, corresponding to a 2 year storm, yields a peak flow down Garden Avenue N of 93.2 c.f.s. which is the approximate capacity of the system in question. For calculation of development contribution, the 2 year storm will be the allowable outlet criteria based on the existing systems capacity. Upgrade Line size Based upon the computed capacity of the existing line down Garden Avenue N and the computed peak 25 year flow, using Manning's equation, it was determined that a 66" pipe with an "n" value of 0.012 is required to parallel the existing 48" RCP. A head of 5.3' is needed to push the 25 year flow through this parallel system of pipes which will discharge into the ponding area on the south side of Lake Washington Boulevard before crossing beneath the road via two 48" CP culverts. Contribution by Park and Garden Plaza On -site detention required for the Park Plaza and Garden Plaza projects was calculated using a 25 year storm with the release rate restricted to the capacity of the existing system (2 year storm). For Page 4 of 5 simplification purposes, all three sites were combined as one with an average CN and the longest Tc taken for the site. The combined sites resulted in an area of 10.4 acres, CN of 92, and the longest Tc being 16 min. Running the calculated numbers through the SCS TR-20 program, a predevelopment 2 year flow of 3.02 c.f.s. was computed. For post development conditions, the same Tc and a CN of 98 were assumed. Passing the post development flows through a simulated detention system (using a structure and reservoir card based on a 66" pipe with a single orifice and overflow at the top of the pipe), successive runs were performed increasing the length of the pipe until the maximum outflow of 3.02 c.f.s. was attained without encountering overflow conditions. The necessary volume to fit these conditions is 18,774 ft$ of detention. This corresponds to approximately 790 l.f. of 66" pipe which is required, in lieu of on -site detention, to fulfill the requirements. Page 5 of 5 ^ frBOM: " DATE: w '--- JOHN R.

The rainfall intensity (I) will be based on the Rainfall Intensit -Duration Curves, prepared by the U. S. Weather Bureau for the area. Ilie curve that is the closest toto the plat will be used (see pages 36 to 43). Where her data of the same nature is used, the engineer should submit the curve along with the design analysis. For drainage areas less than SO acres.Qr producing a runoff of less than 20 cfs, a 10-year design frequency may be used. For areas greater than SO acres " producing a run-off greater than 20 cfs, a 25-year design frequency will be used regardless of the size of the plat. The outlet flow may be further restricted if the downstream drainage basin is presently subject to serious flooding. The time of concentration for rainfall should be computed for all ditches, channels, gutters, culverts and pipe systems. An initial collecting time of 10 minutes for unpaved areas and 5 minutes for paved areas may be taken at the most distant point of flow from a catch basin or culvert. From this point, the overland flow time to the nearest ditch, channel with the flow time for the or gutter may be computed along waterway using Chart 1, page 25, to estimate the velocity for each significantly different slope and overland flow condition. A common error is to combine areas with distinctly different flow patterns such as open, graded, forest and waterways. Once the runoff has reached a storm drainage system, the flow time through the open channel or pipe can be computed. The following minimum roughness coefficients will be used: n = 0.012 for concrete, clay or smooth interior metallic pipes n = 0.024 for annular corrugated metal pipe n = 0.024 will be used for hehical corrugated metal pipe unless the pipe is designed for outlet control or submerged outlet, then the following n values may be used. 3 . 5/79 ---------------- MANNING 'In" PIPE (2-2/3" x 1/211) DIAMETER CORREGATIONS 12" 0.012 15" 0.012 1811 0.014 21" 0.016 24" 0.017 30" 0.018 36" 0.019 42" 0.020 48" 0.021 Storm drain pipe sizes may be selected by nomograph or calculated based on the Manning Formula. Culverts and pipes that are placed in ditches which will pass flows into the storm drainage systems may be designed from a booklet entitled Hydraulic Charts for the Selection of Highway Culverts, by the Bureau of Public Roads. Culverts should e designed to carry the design run-off with a headwater depth not greater than 2.0 times the culvert diameter for culverts 18 inches and under, or 1.5 times the culvert diameter for culverts greater than 18 inches (see pages 27-29). At all times the computed water surface must be at an elevation which will not saturate the base course under the paving. 5/79 K 'I N G COUNTY , W A S r..

Direct Step Backwater Method For Pipes This method of Hydraulic Analysis using Manning's Equation is known as the Direct Step Backwater Method and generally gives more precise results than the simple solution of Mann's Equation given above. It is used to calculate individual head losses in pipe systems which are surcharged and have submerged outlets. These head losses are added to a known downstream water surface elevation to give a design water surface elevation (for a given flow) at the desired upstream location(s). Total head loss = frictional loss + manhole loss + velocity head loss + bend loss + junction loss Frictional loss is computed from Mannings Equation expressed in the form: Sf= (nV)2/2.22 R4/3 = head loss per lineal foot of drain due to friction Where n = Manning's "n" V = Flow velocity in ft/sec = O/A R = Hydraulic Radius The remaining components of total head loss may be computed using standard equations, or they may be estimated using graphical solutions. Figure 7.3.4.0 presents solutions for manhole loss, velocity head loss and bend loss. Manhole loss (curve "A" figure 7.3.4C in the graphic solutions) takes into account the entrance loss encountered when the flow is forced to make a transition into a pipe from a structure such as a manhole or catch basin. Velocity head toss is defined by curve B, figure 7.3.4C in the graphic solutions. Bend loss (curve "C", figure 7.3.4C in the graphic solutions) accounts for the energy required to change direction of flow in a manhole. Junction loss (curve "D", figure 7.3.40 in the graphic solutions) results from the turbulence created when two or more streams are merged into one stream. Several examples of the uses of these graphs are illustrated on the face of the graph. Table 7.3.4 E is provided for convenience.

Construction Period Problems This project will cause serious problems to traffic and utility service if not well scheduled and coordinated. As at the Main/Grady/Benson site, there are problems with staging, moving materials to the site and utility trenching. Because E&H always gets their foundation permits prior to most of the utility design, the two projects here have a major problem because of interfering utilities that the City already owns thru the sites. MEMO July 21, 1987 Page 2 Rnth Citnc Fire Marshall must assign fire flow demands first, then E&H provide fire flow computer analysis to determine watermains needed in City watermain system to provide fire flows. All streets reconstructed/widen must have new 12" minimum) size watermains: North 5th Street - Garden to Park; Park Avenue North - N. 5th to N. 8th; North 6th Street - Garden Ave. N. to Park and perhaps to West.
