As an alternative to the 25 NTU effluent limit noted in Table 5 below (applied at the point where stormwater [or authorized non-stormwater] is discharged off-site), permittees may choose to comply with the surface water quality standard for turbidity. The standard is: no more than 5 NTU over background turbidity when the background turbidity is 50 NTU or less, or no more than a 10% increase in turbidity when the background turbidity is more than 50 NTU. In order to use the water quality standard requirement, the sampling must take place at the following locations: a. Background turbidity in the 303(d)-listed receiving water immediately upstream (upgradient) or outside the area of influence of the discharge. r b. Turbidity at the point of discharge into the 303(d)-listed receiving water, inside the area of influence of the discharge. 3. Discharges that exceed the numeric effluent limit for turbidity constitute a violation of this permit. 4. Permittees whose discharges exceed the numeric effluent limit shall sample discharges daily until the violation is corrected and comply with the non- r compliance notification requirements in Special Condition S5.F.

These BMPs must be functional before other land disturbing activities take place. b. Minimize sediment discharges from the site. The design, installation and maintenance of erosion and sediment controls must address factors such as the amount, frequency, intensity and duration of precipitation,the nature of Construction Stormwater General Permit—December 1, 2010 Page 28 r.► resulting stormwater runoff, and soil characteristics, including the range of soil particle sizes expected to be present on the site. c. Direct stormwater runoff from disturbed areas through a sediment pond or other appropriate sediment removal BMP,before the runoff leaves a construction site or before discharge to an infiltration facility. Runoff from fully stabilized areas may be discharged without a sediment removal BMP,but must meet the flow control performance standard of Special Condition S9.D.3.a. d. Locate BMPs intended to trap sediment on site in a manner to avoid interference with the movement of juvenile salmonids attempting to enter off- channel areas or drainages. ++� e. Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas to increase sediment removal and maximize stormwater infiltration,unless infeasible. £ Where feasible, design outlet structures that withdraw impounded stormwater from the surface to avoid discharging sediment that is still suspended lower in the water column. 5.

Alternatively, the 10- year, 1-hour flow rate predicted by an approved continuous runoff model, go increased by a factor of 1.6,may be used. The hydrologic analysis must use the existing land cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis must use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the Western Washington Hydrology Model (WWHM) to predict flows,bare soil areas should be modeled as "landscaped area." Construction Stormwater General Permit—December 1, 2010 Page 30 .r. ii.

UPSET aw Definition—"Upset"means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based permit effluent limitations because of factors beyond the reasonable control of the Permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit effluent limitations if the requirements of the following at paragraph are met. A Permittee who wishes to establish the affirmative defense of upset must demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: 1) an upset occurred and that the Permittee can identify the cause(s) of the upset; 2) the permitted facility was being properly operated at the time of the upset; 3)the Permittee submitted notice of the upset as required in Special Condition S51, and; 4) the Permittee complied with any remedial measures required under this permit. In any enforcement proceeding, the Permittee seeking to establish the occurrence of an upset has the burden of proof. G16. PROPERTY RIGHTS This permit does not convey any property rights of any sort, or any exclusive privilege. �r G17. DUTY TO COMPLY The Permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit termination,revocation and reissuance, or modification; or denial of a permit renewal application. Construction Stormwater General Permit—December 1, 2010 Page 40 .r ,,. G18. TOXIC POLLUTANTS The Permittee must comply with effluent standards or prohibitions established under Section 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish those standards or prohibitions, even if this permit has not yet been modified to incorporate the requirement. +w G19.

If a conviction of a person is for a violation committed after a first conviction of such person under this condition,punishment shall be a fine of not more than $20,000 per day of violation, or imprisonment of not more than four(4) years, or both. .r G20. REPORTING PLANNED CHANGES The Permittee must, as soon as possible, give notice to Ecology of planned physical w� alterations, modifications or additions to the permitted construction activity. The Permittee should be aware that, depending on the nature and size of the changes to the original permit, a new public notice and other permit process requirements may be required. Changes in �.. activities that require reporting to Ecology include those that will result in: A. The permitted facility being determined to be a new source pursuant to 40 CFR 122.29(b). B. A significant change in the nature or an increase in quantity of pollutants discharged, including but not limited to: for sites 5 acres or larger, a 20% or greater increase in acreage disturbed by construction activity. C. A change in or addition of surface water(s) receiving stormwater or non-stormwater from the construction activity. D. A change in the construction plans and/or activity that affects the Permittee's monitoring requirements in Special Condition S4. Following such notice,permit coverage may be modified, or revoked and reissued pursuant wr to 40 CFR 122.62(a) to specify and limit any pollutants not previously limited. Until such modification is effective, any new or increased discharge in excess of permit limits or not specifically authorized by this permit constitutes a violation. wr wr Construction Stormwater General Permit—December 1, 2010 Page 41 G21. REPORTING OTHER INFORMATION ,rr Where the Permittee becomes aware that it failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or in any report to rr Ecology, it must promptly submit such facts or information. G22. REPORTING ANTICIPATED NON-COMPLIANCE The Permittee must give advance notice to Ecology by submission of a new application or so supplement thereto at least forty-five (45) days prior to commencement of such discharges, of any facility expansions,production increases, or other planned changes, such as process modifications, in the permitted facility or activity which may result in noncompliance with permit limits or conditions. Any maintenance of facilities, which might necessitate unavoidable interruption of operation and degradation of effluent quality, must be scheduled during non-critical water quality periods and carried out in a manner approved by Ecology. G23. REQUESTS TO BE EXCLUDED FROM COVERAGE UNDER THE PERMIT Any discharger authorized by this permit may request to be excluded from coverage under the general permit by applying for an individual permit. The discharger must submit to the Director an application as described in WAC 173-220-040 or WAC 173-216-070, whichever is applicable, with reasons supporting the request. These reasons will fully document how an individual permit will apply to the applicant in a way that the general permit cannot. Ecology may make specific requests for information to support the request. +• The Director will either issue an individual permit or deny the request with a statement explaining the reason for the denial. When an individual permit is issued to a discharger otherwise subject to the construction stormwater general permit, the applicability of the + ► construction stormwater general permit to that Permittee is automatically terminated on the effective date of the individual permit. w G24. APPEALS ■r A. The terms and conditions of this general permit, as they apply to the appropriate class of dischargers, are subject to appeal by any person within 30 days of issuance of this general permit, in accordance with Chapter 43.21B RCW, and Chapter 173-226 WAC. B. The terms and conditions of this general permit, as they apply to an individual discharger, are appealable in accordance with Chapter 43.21B RCW within 30 days of the effective date of coverage of that discharger. Consideration of an appeal of general permit coverage of an individual discharger is limited to the general permit's applicability or nonapplicability to that individual discharger. C. The appeal of general permit coverage of an individual discharger does not affect any other dischargers covered under this general permit. If the terms and conditions of this general permit are found to be inapplicable to any individual discharger(s), the matter "' Construction Stormwater General Permit—December 1, 2010 Page 42 WW M shall be remanded to Ecology for consideration of issuance of an individual permit or permits. G25. SEVERABILITY The provisions of this permit are severable, and if any provision of this permit, or °�` application of any provision of this permit to any circumstance, is held invalid, the application of such provision to other circumstances, and the remainder of this permit shall not be affected thereby. rrr G26. BYPASS PROHIBITED rr A. Bypass Procedures Bypass, which is the intentional diversion of waste streams from any portion of a treatment facility, is prohibited for stormwater events below the design criteria for stormwater management. Ecology may take enforcement action against a Permittee for wr bypass unless one of the following circumstances (1, 2, 3 or 4) is applicable. 1. Bypass of stormwater is consistent with the design criteria and part of an approved management practice in the applicable stormwater management manual. 2. Bypass for essential maintenance without the potential to cause violation of permit limits or conditions. Bypass is authorized if it is for essential maintenance and does not have the potential to cause violations of limitations or other conditions of this permit, or adversely impact public health. 3. Bypass of stormwater is unavoidable, unanticipated, and results in noncompliance Ww� of this permit. This bypass is permitted only if: rrr a. Bypass is unavoidable to prevent loss of life,personal injury, or severe property damage. "Severe property damage"means substantial physical damage to property, damage to the treatment facilities which would cause ••� them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. wa b. There are no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, maintenance during normal periods of equipment downtime (but not if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment irr downtime or preventative maintenance), or transport of untreated wastes to another treatment facility. �r Construction Stormwater General Permit—December 1, 2010 Page 43 wfi c. Ecology is properly notified of the bypass as required in Special Condition S51 of this permit. 4. A planned action that would cause bypass of stormwater and has the potential to result in noncompliance of this permit during a storm event. The Permittee must notify Ecology at least thirty(30) days before the planned date of bypass. The notice must contain: a. a description of the bypass and its cause b. an analysis of all known alternatives which would eliminate, reduce, or mitigate the need for bypassing. c. a cost-effectiveness analysis of alternatives including comparative resource damage assessment. d. the minimum and maximum duration of bypass under each alternative. e. a recommendation as to the preferred alternative for conducting the bypass. f. the projected date of bypass initiation. g. a statement of compliance with SEPA. h. a request for modification of water quality standards as provided for in WAC 173-201A-I 10, if an exceedance of any water quality standard is anticipated. i. steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. 5. For probable construction bypasses, the need to bypass is to be identified as early in the planning process as possible. The analysis required above must be considered during preparation of the Stormwater Pollution Prevention Plan (SWPPP) and must be included to the extent practical. In cases where the probable need to bypass is determined early, continued analysis is necessary up to and including the construction period in an effort to minimize or eliminate the bypass. rrt Ecology will consider the following before issuing an administrative order for this type bypass: a. If the bypass is necessary to perform construction or maintenance-related activities essential to meet the requirements of this permit. b. If there are feasible alternatives to bypass, such as the use of auxiliary treatment facilities,retention of untreated wastes, stopping production, maintenance during normal periods of equipment down time, or transport of untreated wastes to another treatment facility. c. If the bypass is planned and scheduled to minimize adverse effects on the public and the environment. Construction Stormwater General Permit—December 1, 2010 Page 44 as a w After consideration of the above and the adverse effects of the proposed bypass and any other relevant factors, Ecology will approve, conditionally approve, or deny the request. The public must be notified and given an opportunity to iw comment on bypass incidents of significant duration, to the extent feasible. Approval of a request to bypass will be by administrative order issued by Ecology under RCW 90.48.120. Ore B. Duty to Mitigate The Permittee is required to take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit that has a reasonable likelihood of adversely affecting human health or the environment. an ai a. ara� aar ra aa.

Process wastewater means any water which, during manufacturing or processing, comes into direct contact with or results from the production or use of any raw material, intermediate product, finished product,byproduct, or waste product (40 CFR 122.1). ai Receiving water means the water body at the point of discharge. If the discharge is to a storm sewer system, either surface or subsurface, the receiving water is the water body to which the storm system discharges. Systems designed primarily for other purposes such as for ground water drainage, redirecting stream natural flows, or for conveyance of irrigation water/return flows that coincidentally convey stormwater are considered the receiving water. Representative means a stormwater or wastewater sample which represents the flow and characteristics of the discharge. Representative samples may be a grab sample, a time- proportionate composite sample, or a flow proportionate sample. Ecology's Construction Stormwater Monitoring Manual provides guidance on representative sampling. Sanitary sewer means a sewer which is designed to convey domestic wastewater. Sediment means the fragmented material that originates from the weathering and erosion of rocks or unconsolidated deposits, and is transported by, suspended in, or deposited by water.

Temporary stabilization is not a rrt substitute for the more permanent"final stabilization." Total Maximum Daily Load(TMDL) means a calculation of the maximum amount of a pollutant that a water body can receive and still meet state water quality standards. Percentages of the total maximum daily load are allocated to the various pollutant sources. A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and nonpoint sources. The girt TMDL calculations must include a "margin of safety" to ensure that the water body can be protected in case there are unforeseen events or unknown sources of the pollutant.

(HWA) for the final selected alignment for the proposed storm drain improvement project along a corridor of SW 7th Street in Renton, Washington. The err purpose of this investigation was to evaluate the subsurface conditions along the selected alignment and to provide recommendations for design. We previously performed a geotechnical investigation to evaluate three proposed alternative alignments for the new storm sewer(HWA, 2012). All of the subsurface explorations were performed as part of the initial investigation. 1.2 PROJECT DESCRIPTION Our understanding of the project is based on discussions with and design information provided by Mr. Mike Giseburt of Leidos. We understand that the City of Renton plans to increase the storm drainage capacity for the project area. The general location of the site is shown on the Vicinity Map, Figure 1. Locations of our subsurface explorations in relation to the site are shown in Figure 2. The selected alignment is described below: ' The alignment begins at the intersection of SW 7th Street and Lind Avenue SW, where the new 60-inch diameter storm drain connects to an existing stormwater .w vault. The alignment then extends west in SW 7th Street to Naches Avenue SW and then extends north in Naches Avenue SW and drains into the open-channel drainage swale on the west side of Naches Avenue SW. New manholes and r,. Filterra water quality vaults will be installed as part of the project. Based on conversations with the design team, we understand that the project will be rr separated into phases with the first phase consisting of the portion from Powell Avenue to the north end at Naches Avenue, while the second phase will consist of the portion from Lind Avenue to Powell Avenue. We further understand that the new storm drain will generally be constructed adjacent to the existing storm drain and that the new drain pipe will be constructed at about the same invert elevation as the existing pipe, which is rrr about 10 feet below ground surface. wr April 15, 2014 HWA Project No. 2011-044-21 1.3 SCOPE OF SERVICES AND AUTHORIZATION A proposed scope of services and cost estimate for finalizing the geotechnical report was submitted by HWA to Leidos (formerly SAIC). Authorization for the work was subsequently provided in a Subconsultant Agreement, dated November 8, 2013. The scope of work completed for this portion of the project included reviewing and preparing ,rr relevant specifications and finalizing the geotechnical engineering report for the selected alignment. 2.0 FIELD AND LABORATORY INVESTIGATIONS 2.1 SITE EXPLORATIONS On October 12 through 14, 2011, HWA monitored the drilling of eight exploratory boreholes, designated BH-1 through 13H-8. These boreholes were performed by Holocene Drilling of Edgewood, Washington, under subcontract to HWA, using a truck- mounted drill employing hollow-stem auger drilling techniques. Boreholes extended to depths of about 30 feet below ground surface. A 2-inch diameter piezometer was installed in boreholes BH-1 and BH-3, with the slotted screen installed at a depth of 20 to 30 feet. Standard Penetration Test (SPT) sampling was performed in each borehole using a 2-inch outside diameter split-spoon sampler and a 140-pound auto-hammer. During the SPT, samples were obtained by driving the sampler 18 inches into the soil with the hammer free-falling 30 inches. The numbers of blows required for each 6 inches of penetration „o were recorded. The Standard Penetration Resistance ("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration. This resistance, or N-value,provides an indication of relative density of granular soils and the relative No consistency of cohesive soils;both indicators of soil strength and foundation bearing capacity. In several of the boreholes, a 3-inch diameter split-spoon sampler was used due to poor recovery with the 2-inch sampler. The borehole logs indicate the depth at which the as standard sampler was switched to a 3-inch diameter. The number of blows required to advance the larger diameter sampler with the standard 140-pound hammer are greater than SPT penetration resistance due to the lower energy imparted, given the larger diameter sampler and same hammer weight. To avoid confusion, the number of blows required for the final 12 inches of penetration in these non-standard penetration test (NSPT) samples, are not plotted on our boring logs. 2011-044-21 SW 7th Street Final Report April 2014 2 HWA GEOSCIENCES INC. 66 to April 15, 2014 HWA Project No. 2011-044-21 The locations of the boreholes were determined approximately in the field by pacing and taping distances from existing site features and are shown on the Site and Exploration " Plan, Figure 2. A geotechnical engineer and/or geologist from HWA logged each exploration and recorded all pertinent information. Soil samples obtained from the boreholes were classified in the field and representative portions were placed in plastic bags. These soil samples were then taken to our Bothell, Washington, laboratory for further examination and testing. Pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and ground water occurrence was recorded. The stratigraphic r contacts shown on the individual exploration logs represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil and ground water conditions depicted are only for the specific date and locations reported and, therefore, are not necessarily representative of other locations and times. A legend of the terms and symbols used on the exploration logs is presented in Figure A-1. Summary logs of the borehole explorations are presented in Figures A-2 through A-9. 2.2 PREVIOUS EXPLORATIONS IN THE VICINITY In 2003, HWA performed a geotechnical engineering investigation for a previous phase of storm drain work along 7th Avenue SW(HWA, 2003). Three of the boreholes, designated BH-1 through BH-3,performed for that phase are located in the vicinity of this new project, as shown in blue type on Figure 2. These previous boreholes are designated with `2003', in order to avoid confusion with the borehole designations performed for this new investigation. The logs of the previous boreholes are presented in Appendix C. All three of these previous boreholes extended to about 30 feet below ground surface and a 2-inch diameter piezometer was installed in each, with the slotted screen installed from w■ about 20 to 30 feet below ground surface, as shown on the logs in Appendix C. In addition to the borehole logs, laboratory test results for the three previous boreholes are included in Appendix C following the borehole logs. 2.3 LABORATORY TESTING .. Representative soil samples obtained from the subsurface explorations were taken to the HWA laboratory for further examination and testing. Laboratory tests were conducted on selected soil samples to characterize engineering properties of the soils. Laboratory tests, as described below, included moisture content determination, Atterberg limits and grain size distribution. The results of the laboratory testing are presented in Appendix B and in the paragraphs below. 2011-044-21 SW 7th Street Final Report April 2014 3 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 Moisture Content of Soil: The moisture content(percent by dry mass) of selected soil samples was determined in general accordance with ASTM D 2216. The results are shown at the sampled intervals on the appropriate borehole logs in Appendix A. Liquid Limit, Plastic Limit, and Plasticity Index of Soils (Atterberg Limits): Select fine-grained samples were tested using method ASTM D 4318, multi-point method. The results are reported on the attached Liquid Limit, Plastic Limit, and Plasticity Index report, Figure B-1. Particle Size Analysis of Soils: Selected borehole samples were tested to determine the particle size distribution of material in general accordance with ASTM D422. The results are summarized on the attached Grain Size Distribution Reports, Figures B-2 through B- 9, which also provides information regarding the classification of the samples and the moisture content at the time of testing. 3.0 SITE CONDITIONS 3.1 SURFACE CONDITIONS The project site is located near downtown Renton in a residential and light commercial area, as shown on the Vicinity Map, Figure 1. Site topography is relatively flat, with maximum relief of about 6 feet across the site (excluding drainage channels and streams). + ► 3.2 GENERAL GEOLOGIC CONDITIONS go The Puget Lowland has repeatedly been occupied by a portion of the continental glaciers that developed during the ice ages of the Quaternary period. During at least four periods, portions of the ice sheet advanced south from British Columbia into the lowlands of western Washington. The southern extent of these glacial advances was near Olympia, Washington. Each major advance included numerous local advances and retreats, and each advance and retreat resulted in its own sequence of erosion and deposition of glacial lacustrine, outwash and drift deposits. Between and following these glacial advances, sediments from the Olympic and Cascade Mountains accumulated in the Puget Lowland. As the most recent glacier retreated, it uncovered a sculpted landscape of elongated, north-south trending hills and valleys between the Cascade and Olympic mountain ranges, composed of a complex sequence of glacial and interglacial deposits. Post- glacial deposits within the Puget Lowland include alluvium, lacustrine deposits, volcanic mudflow deposits, and landslide deposits. The project area is located in the geologically recent floodplain of the Cedar River and former Black River, a site of deposition since the retreat of the last glacier some 13,000 years ago. Post-glacial alluvial sediments include fine sands and silts deposited in slow- 2011-044-21 SW 7th Street Final Report April 2014 4 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 moving water; coarse sands and gravels deposited in faster-moving active channels; and clayey silts, organic silts, and peats, deposited in still water such as ponds, oxbow lakes and Lake Washington. Portions of the proposed alignment cross the former channel of the Black River which was the outlet of Lake Washington until the early 20`h century. The Black River flowed to the Duwamish River until 1916 when the opening of the Lake "r Washington Ship Canal lowered the lake level and the Black River went dry (Galster and Laprade, 1991). A present-day drainage, also named the Black River, originates in wetlands approximately eight miles south of the project alignment and flows northwesterly through the P-1 forebay(located in the Black River Riparian Forest northwest of the project area) before its confluence with the Duwamish River in Tukwila. ,r. 3.3 SUBSURFACE CONDITIONS Geological information for the site was obtained from the Geologic Map of the Renton Quadrangle, King County, Washington (Mullineaux, 1965). The geologic map indicates that the project area is generally underlain by recent alluvium consisting of sand and gravel with peat, silt and clay. The map indicates that the western approximately one-third of the project area is aw underlain by recent alluvium, described as chiefly sand, silt and clay deposited by the Black, White, and Green Rivers before diversion of the White River to the south in 1906 and lowering of the Lake Washington water surface in 1916. The map indicates that the upper part of the alluvium is typically comprised of clayey silt and fine sand, while the lower part of the deposit consists mostly of medium and coarse sand. .r The eastern approximately two-thirds of the project area is underlain by recent alluvium described as sand and gravel deposited by the Cedar River along with associated thin +wr beds of silt, clay and peat. Based on our borings, the storm drain alignment is generally underlain by a sequence of or fill and alluvium. Fill was encountered directly beneath the pavement in nearly all of the borings, extending +ter to depths of approximately 2.5 to 7.5 feet. The fill consisted generally of loose to medium dense, clean to slightly silty, sand and gravel. Some of the fill encountered in these borings could be utility trench backfill from nearby utilities. Recent alluvium was encountered immediately below the fill in all of our explorations and extended the entire depth of the explorations. The alluvium consists of interbedded, very loose to medium dense, clean to very silty sand, and very soft to medium stiff, dark, organic silt,peat, and silt. These materials are relatively fine-grained and were deposited in a low-energy environment such as a lake or shallow estuary. They are moderately to 2011-044-21 SW 7th Street Final Report April 2014 5 HWA GEOSCIENCES INC. do April 15, 2014 HWA Project No. 2011-044-21 .ir highly compressible and have relatively low shear strengths. They may contain logs, stumps or other woody debris. These deposits are described as Alluvial Silts and Sands on the borehole logs. The borings also encountered a higher energy(i.e., deposited by faster moving water), coarser deposit of alluvium consisting of sands and gravel containing cobbles and possibly boulders. The coarser alluvial soils are generally present below the fine-grained alluvium, although there are occasional layers of one within the other. These deposits are described as Alluvial Sands and Gravels on the borehole logs. The higher energy, coarse alluvium consists of medium dense to dense, gray to brown, clean to silty gravelly sand and sandy gravel, with occasional cobbles. Trace organic debris, consisting of sticks, roots, and other organic matter was encountered in several samples. Although no boulders were identified in the explorations, boulders may be present in the coarse alluvium. Because the borings were not drilled in the exact locations of the proposed pipeline to alignment and the alluvial soils vary considerably in short distances, actual soil conditions in the pipeline excavation may be different than indicated. 3.3.1 Ground Water Ground water was encountered in all borings during drilling at depths varying from approximately 4 to 14 feet below ground surface, with most ground water levels in the vicinity of about 7 to 10 feet below ground surface. A 2-inch diameter PVC piezometer was installed in boreholes BH-1 and BH-3 to monitor ground water levels. Ground water levels taken about two weeks after drilling indicated water levels of 10.6 feet and 7.9 feet below road surface in boreholes BH-1 and BH-3, respectively. It is anticipated that ground water conditions will change in response to rainfall, time of year and other factors. 3.3.2 Aquifer Testing and Analysis HWA performed testing and data analyses to estimate aquifer hydraulic conductivities. rr Our aquifer testing included single-well,post-pumping ground water level recovery tests at piezometers BH-1 and BH-3. The recovery tests were performed by pumping piezometers BH-1 and BH-3 at a constant rate until the pumping water level stabilized(45 to 65 minutes),then recording the water level in each piezometer until it recovered to pre-test levels. During the test,water level changes were monitored by a datalogging pressure transducer. as 2011-044-21 SW 7th Street Final Report April 2014 6 HWA GEOSCIENCES INC. we April 15, 2014 HWA Project No. 2011-044-21 an HWA analyzed the results of the pumping tests using the Aquifer Test for Windows Version 3.0 software (Waterloo Hydrogeologic, 2001). We used the Theis recovery method included in the software to analyze the pumping test recoveries in wells BH-1 and BH-3. This method is appropriate for confined or semi-confined aquifer conditions, and is also appropriate for unconfined aquifer conditions if the water level drawdown during pumping is small compared to the saturated thickness of the aquifer. The analysis for each piezometer was compensated for partial penetration well completions. An �r► estimated aquifer thickness of 50 feet was used for calculation purposes. Refer to Table 1 for hydraulic conductivity values determined through the testing and analyses. Appendix C contains printouts from the AquiferTest software used to analyze the test results. Table 1.

The hydraulic conductivities calculated by pumping methodologies (approximately 5x10-2 to 8x10-2 cm/sec) are representative of granular alluvial materials. As expected, we the hydraulic conductivity is slightly higher in the coarse-grained materials observed at boring BH-1. The range is within that expected for the observed aquifer materials (Freeze and Cherry, 1979). aw 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 GENERAL We understand that the new storm drain will generally be constructed adjacent to the existing storm drain. The soils along the proposed alignment consist of recent alluvial deposits along the entire project site. �r #W 2011-044-21 SW 7th Street Final Report April 2014 7 HWA GEOSCIENCES INC. W April 15, 2014 HWA Project No. 2011-044-21 Based on the subsurface conditions encountered in our geotechnical investigation, the following constraints will affect the design and construction of the proposed project: w • The proposed pipeline will traverse loose, soft alluvial soils below the ground water table. These soils include compressible clays, silts and peat, in addition to sands and gravels containing occasional cobbles. Logs or other wooden debris and occasional boulders also may be present along the proposed pipe alignment. • In some areas the proposed storm sewer invert will extend below ground water. Construction dewatering will be necessary. • Ground water seepage/flow into excavations will likely be greater where existing subsurface utility trenches are encountered, as these were likely backfilled with permeable, granular materials that convey water more easily than some of the native, .r fine-grained alluvial soils. • The potential need to minimize surface disruptions during construction along with the r desire to avoid undermining existing utilities, structures and roadway due to soil sloughing and caving using traditional trench box shoring methods. Based on these concerns, our recommendations include using either braced steel plates, steel sheetpiles, sinking trench box (Slide Rail system) shoring or traditional trench boxes to support the excavation. These recommendations will provide for flexibility in the method to support the excavation sidewalls and limit dewatering and ground water flow into the excavation. The following sections provide recommendations for seismic considerations, foundation design, shoring, construction dewatering,backfill,hazardous materials and other construction considerations. 4.2 FOUNDATION CONSIDERATIONS 4.2.1 Seismic Considerations Soil liquefaction is a phenomenon wherein saturated soil deposits temporarily lose strength and behave as a liquid in response to earthquake shaking. Soil liquefaction is generally limited to loose granular soils located below the water table. ' The upper alluvial soils in the project area have a high susceptibility to liquefaction. Evidence of liquefaction was observed in the project area during the 1965 magnitude 6.5 Seattle-Tacoma earthquake. 2011-044-21 SW 7th Street Final Report April 2014 8 HWA GEOSCIENCES INC. rrr April 15, 2014 HWA Project No. 2011-044-21 However, in our opinion, trench backfill compacted as specified in further sections of this report will have little or no liquefaction potential. It would be impractical to design this project to mitigate for potential liquefaction effects. 4.2.2 Foundation Conditions and Pipe Bedding Along most of the alignment, the soils at the proposed storm drain invert elevation consist of very soft to soft silt, and loose silty sand. It will not be feasible to remove these soils, as these deposits extend to considerable depths. To provide suitable support and bedding for the pipe, we recommend the storm drain be founded on suitable bedding material meeting the requirements of Gravel Borrow for Pipe Zone Bedding, Section 9- 03.12(3) of the WSDOT Standard Specifications (WSDOT, 2012). To minimize trench subgrade disturbance during excavation, the excavator should use a smooth-edged bucket ,w. rather than a toothed bucket. Pipe bedding should provide a firm uniform cradle for support of the pipes. A minimum 12-inch thickness of bedding material beneath the pipe should be provided. Prior to installation of the pipe, the pipe bedding should be shaped to fit the lower part of the pipe exterior with reasonable closeness to provide uniform support along the pipe. Pipe W& bedding material should be used as pipe zone backfill and placed in layers and tamped around the pipes to obtain complete contact. To protect the pipe, bedding material should extend at least 12 inches above the top of the pipe. In areas where the subgrade soils in the trench excavation consist of fine-grained soils, such as silt/clay, or organic rich soils, we recommend that 1 to 2 feet of these soils be over-excavated and replaced with clean sand backfill. A geotextile separator fabric should be placed over the native soils prior to placement of the clean sand/pipe bedding. We recommend that the geotextile meet the requirements of WSDOT Standard Specifications (WSDOT, 2012) Section 9-33.2(1) Table 3 for Separation. We recommend that a qualified earthworks inspector observe subgrade conditions during construction and determine if and where a separator is necessary, in addition to providing full-time monitoring of all backfilling operations. rr We recommend that all manhole, vault and Filterra structures be founded on a minimum of 6 inches of Crushed Surfacing Top Course (CSTC) meeting the requirements of Section 9-03.9(3) of the WSDOT Standard Specifications(WSDOT, 2012). A separator fabric, as described above, should be placed below the CSTC where fine-grained soils, such as silt/clay, or organic rich soils are encountered at the base of the excavation. OW im Orr 2011-044-21 SW 7th Street Final Report April 2014 9 HWA GEOSCIENCES INC. to April 15, 2014 HWA Project No. 2011-044-21 4.3 TEMPORARY SHORING Excavations for the storm sewer trench can be accomplished with conventional excavating equipment such as backhoes and trackhoes. Because of the nature of the alluvial soils, the high ground water table, potential for flowing sands, and the depths of excavation, the excavations will require construction dewatering and temporary shoring. We have identified three methods by which the excavation could be shored: traditional trench boxes, steel plates with hydraulic/adjustable bracing and driven/vibrated .r interlocking sheet piles with internal bracing. In some areas, trench boxes may not provide adequate sidewall support and could allow .r soils to slough and cave, resulting in loss of support for existing utilities and the road surface. These soft/loose soils have the potential to slough to slopes approaching 1.25H:1 V (horizontal:vertical). Where utility and roadway protection is of more concern, steel plates with adjustable or hydraulic bracing may be used for temporary shoring. Excavation to, or slightly below, the water table may be possible before placement of the steel plates. Thereafter, excavation could continue within the plates. at Where it is necessary to minimize the area affected by trench excavation, and/or protect nearby structures or utilities, the use of interlocking sheetpiles may be required. The use of sheetpiles would also minimize ground water flow into the excavation and limit the amount of dewatering required,protecting nearby utilities and structures from settlements associated with dewatering. The temporary shoring should be designed to resist the lateral earth pressures resulting from the soil and ground water as well as any traffic and/or construction surcharge loads. Figure 3 presents lateral earth pressures for use in temporary shoring design assuming ground water at the ground surface. wr We recommend that the contractor be required to submit a shoring/excavation plan for review prior to construction. The plan should be required to contain specific measures VAN for temporary support and protection of the existing utilities and structures. Precautions should be taken during removal of the shoring to minimize disturbance of the pipe, underlying bedding materials, and native soils. Maintenance of safe working conditions, including temporary excavation stability, is the responsibility of the contractor. In accordance with Part N of WAC (Washington Administrative Code) 296-155, all temporary cuts in excess of 4 feet in height should be sloped or shored. The existing native soils generally consist of loose sands and soft silt. These sand deposits generally classify as Type C soil, per WAC 296-155, and, if no 2011-044-21 SW 7th Street Final Report April 201410 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 wr shoring is used, should be sloped no steeper than 1'/2H:1 V. Flatter side slopes will be required where ground water seepage is encountered. 4.4 DEWATERING HWA estimated the maximum ground water inflows to the open trench during construction using a spreadsheet model based upon equations presented in Powers and others (2007). Assumptions underlying these equations are: rr • The length of the trench is much greater than the width r • The aquifer is unconfined • The extent of the water table decline around the trench during dewatering ,rr activities is less than the distance to any nearby ground water recharge source such as a stream or lake • Ground water flow to the trench is steady state err Data we used in the spreadsheet model were: „�, • Depth to ground water is 4 to 8 feet bgs • Trench depth is 8 to 10 feet below existing grade ,,�, • Trench width is 10 feet • The distance to the nearest surface water features, the P-1 channel and P-1 ow forebay, is approximately 2,400 ft • Aquifer thickness is 50 feet • Aquifer hydraulic conductivity is 4.9x10-2 to 7.6x10-2 centimeters per second(140 to 215 feet per day)per Table 1 above • We assumed that the contractor would have 100 feet of trench open at any time. Our analysis of ground water inflow to the trench is presented in Appendix D. The estimated ground water inflow to the trench is approximately 500 gallons per minute (gpm). However, it should be noted that ground water conditions can vary substantially over time, and over relatively short distances. For example, during construction it is possible that: .r� • The aquifer thickness and hydraulic conductivity are not constant over the entire project distance and may vary considerably • Zones of higher water table elevation may be encountered during construction • Unanticipated sources of ground water recharge may be encountered r 2011-044-21 SW 7th Street Final Report April 201411 HWA GEOSCIENCES INC. Ow April 15, 2014 HWA Project No. 2011-044-21 • Construction dewatering total flow rates may initially be higher than estimated if excavation begins during the rainy season,but should decline after the water table equilibrates In particular, ground water flow rates greater than our estimated 500 gpm may be encountered between Hardie and Lind Avenues SW where the project crosses and runs parallel to the alignment of the former Black River because ground water may preferentially flow in the alluvial sediments in that section of the project. If project Alternative 1 or 2 is selected, then significant quantities of ground water may also be encountered in the vicinity of Naches Avenue SW which is in close proximity to the former Black River alignment. Accordingly, the dewatering contractor should be prepared to encounter trench inflow rates different than estimated here. Ground water flow rates into the trench will be lowest if construction occurs during the summer and early fall. Dewatering will likely require dewatering wells or well points in some or all areas. Settlement of adjoining ground surface, structures or utilities may occur due to dewatering activities. Dewatering should be performed in such a way as to rr not cause settlements or damage to adjacent areas, which may require reinjection of ground water. Design and implementation of any dewatering system is the responsibility of the contractor. Dewatering systems should be designed and submitted to the project engineer for approval prior to the commencement of the excavation. 4.$ FILL PLACEMENT AND MATERIALS In general the existing soils that will be excavated are very silty and organic-rich, and they will be unsuitable for re-use as trench backfill. Where granular structural fill is utilized, it should consist of Gravel Borrow meeting the requirements of Section 9-03.14(1) of the WSDOT Standard Specifications(WSDOT, 2012). It should be free of gravel, organics and other debris. The on-site soil removed from the excavation will generally not be suitable for reuse as structural fill, due to the abundance of soft, wet, organic, silty soils. The structural trench backfill should be moisture conditioned to within about 3 percent of optimum moisture content, placed in loose horizontal lifts less than 6 inches in thickness, and compacted to at least 95 percent of the maximum dry density(MDD), determined using test method ASTM D 1557 (Modified Proctor). mi Trench backfill should be densely compacted in a systematic manner. The contractor should develop compaction methods that consistently produce adequate compaction levels. All backfilling operations should be monitored full-time by a qualified inspector and a sufficient number of in-place density tests should be performed as the fill is placed to determine that the required compaction is being achieved. wr 2011-044-21 SW 7th Street Final Report April 201412 HWA GEOSCIENCES INC. iwr April 15, 2014 HWA Project No. 2011-044-21 +rr During placement of the initial lifts, the trench backfill material should not be bulldozed into the trench or dropped directly on the pipe. Furthermore, heavy vibratory equipment should not be permitted to operate directly over the pipe until a minimum of 2 feet of backfill has been placed over the pipe bedding. A significant cause of large settlement results from inadequate shoring practices and poor compaction during shoring removal and backfilling. Special care must be taken to obtain good compaction up to the edges of the excavation as the shoring is removed. Moreover, attention must be paid to ensuring good compaction around manholes. 4.6 SURFACE RUNOFF Surface runoff control during construction should be the responsibility of the contractor, ,Ir and should be treated prior to discharge so as to comply with State water quality standards. Grading measures, slope protection, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of the work. wr 5.0 HAZARDOUS MATERIALS 5.1 HAZARDOUS MATERIALS HWA evaluated the project alignment for the potential presence of contamination that may present issues during construction, by conducting a search for listed contaminated sites along the alignment, and reviewing files available at the Washington State Department of Ecology(Ecology) and provided by the City of Renton. Eighteen listed sites were identified along or adjoining the project alignment. Of these, w. four(highlighted in yellow below) with documented releases of contaminants into the environment were further evaluated with file reviews, and are described below.

No visual, odor, or other indications of contamination were observed during our exploration program. at 5.1.1 Black River Corporate Park HWA reviewed files provided by the City of Renton and available at Ecology. The Black River Corporate Park site described in the files includes areas north of Oakesdale Avenue South and Southwest 7th Street, extending west of Naches Street some 1600 feet. The western half of this area is known as Tract A, and the eastern half as Tract B or the Phase VIII property. Dredge spoils were deposited on Tract A around 1984. Sampling in 1990 and 1991 indicated the presence of petroleum hydrocarbons and metals in the 2011-044-21 SW 7th Street Final Report April 201414 HWA GEOSCIENCES INC. `' VIA ■r. April 15, 2014 HWA Project No. 2011-044-21 dredge spoils. Later sampling(ca. 1997) on Tract B revealed petroleum hydrocarbons and metals in a drainage swale/channel. A corporate office/business park was constructed on the southeast portion of Tract B, and the remaining portion of Tract was acquired by the City of Renton. This remaining City owned parcel is currently under consideration for proposed stormwater improvements as part of the Hardie Ave. SW— SW 7th St. project. Hart Crowser conducted a Supplemental Environmental Assessment at Tract B in 1997. Previous investigations found fill soils within a drainage and wetland area on the site contained petroleum hydrocarbons (TPH), lead, and cadmium exceeding Ecology Model Toxics Control Act (MTCA) cleanup levels. Hart Crowser collected shallow(0 to 3 feet below ground surface, (bgs)) soils from hand auger borings and test pits throughout Tract «■ B, with emphasis in a drainage course at the northeastern edge of the property. Shallow samples, typically consisting of wetland vegetation and organic silts, generally did not exceed MTCA cleanup levels for the selected analytes (Hart Crowser, 1997). Deeper samples (1.5 feet bgs and below) contained metals and TPH exceeding MTCA cleanup levels. The contaminated soils appeared to be concentrated within a swale that conveyed stormwater discharge from a former stormwater outfall, and other(more upland) areas on the site generally did not have exceedances. Although the former property owners and consultants attributed the source of contamination to stormwater flowing through this area, the concentrations observed are in some cases higher than what might be expected solely from stormwater runoff. Hart Crowser estimated the volume of affected soils to range from 1,000 to 9,000 cubic yards. Ground water samples were not collected as part of their investigation. .r The City-owned portion of Tract B (containing contaminated soils) may be an alternative location for a stormwater facility(i.e., a wetpond and possibly a new storm pipe). Proposed construction should be designed to minimize the disturbance of contaminated soils in this area. The impacted soils are currently located below cleaner silts and vegetation, and construction or excavation of drainage features should be avoided if at all possible. Additional exploration and sampling should be conducted in areas proposed for construction to evaluate the presence and extent of contaminated soils, and to estimate contaminated soil volumes, cleanup costs, and to prepare hazardous materials handling and disposal specifications for construction. Collected soil and ground water samples should be analyzed for petroleum hydrocarbons and metals at an accredited analytical laboratory. 2011-044-21 SW 7th Street Final Report April 201415 HWA GEOSCIENCES INC. rrr Ali April 15, 2014 HWA Project No. 2011-044-21 rr 5.1.2 US West, Renton Admin. Building (300 SW 7" Street) The site is located on the north side of SW 7th Street and is a listed leaking underground storage tank(LUST) site. Delta Environmental Consultants (Delta, 1994)prepared a UST site assessment report for the site. Two 6,000 gallon gasoline underground storage tanks (USTs) and one 300 gallon diesel UST were removed from the site. The tanks 0 were located on the north side of the building, some 200 feet north of SW 7th Street. Releases from the USTs were not observed, and post-removal soil samples collected from the UST excavations either did not contain detectable concentrations of TPH, or the concentrations were below cleanup levels. Delta observed petroleum-affected soils beneath a fuel dispenser. Approximately 65 cubic yards of soil was removed and stockpiled for analysis. Approximately ten cubic yards were subsequently removed from the site for treatment. The contamination was assumed to be associated with overfill and/or spills. Ground water was encountered at ten feet bgs,but was not sampled at the time. ww Delta prepared an addendum to an Independent Remedial Action Report(not in the file but referenced as March 1996). A soil boring and ground water monitoring well were installed in the inferred downgradient position of the former USTs at Ecology's request for closure of the Independent Remedial Action. Ground water was encountered at eight feet bgs. Soil and ground water samples collected from the monitoring well did not contain detectable concentrations of TPH. Ecology provided a No Further Action (NFA) letter for the site in April 1996. Based on the available documentation and location of the releases, it is unlikely that contamination from the U.S. West site will affect soils in the project corridor due to the limited release to soils at the site and lack of evidence of ground water contamination. 5.1.3 K&N Meats (601 SW 71" Street) The site is located on the south side of SW 7th Street and is a listed LUST site. B&C Equipment (1990)prepared a letter report documenting soil and ground water sampling associated with removal of one 10,000 gallon gasoline, one 10,000 gallon diesel, and one aril 500 gallon waste oil UST from the site. Multiple soil samples were collected from the excavation sidewalls at the approximate soil-ground water interface at seven feet bgs. Additionally, B&C collected a water sample from standing ground water within the excavation. The samples were analyzed for TPH and BTEX (benzene, toluene, ethylbenzene, and xylenes). Several post-excavation soil samples exceeded 200 milligram per kilogram(mg/kg) (the MTCA petroleum cleanup level in effect at the time of the UST removal), and overexcavation of selected areas was performed to remove these soils. After 2011-044-21 SW 7th Street Final Report April 201416 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 overexcavation, The TPH concentration in one southwest sidewall sample (1,187 mg/kg) exceeded the 200 mg/kg MTCA cleanup level. The soil sampling location was adjacent to a street or structure and was not removed. The report included a hand-drawn sketch map of the excavation and sampling locations, but with no other features (e.g., streets, buildings) that provide information as to the actual location of the samples. The remainder of the post-excavation samples either did not contain detectable aw concentrations of TPH, or the concentrations were below cleanup levels. TPH and BETX were detected in the initial excavation water sample. A second water sample was collected after overexcavation and pumping, and the subsequent sample did not contain detectable concentrations of TPH or BTEX, or the concentrations were below cleanup levels. A total of 182 cubic yards of petroleum-affected soils were disposed of at the Cedar Hills Regional Landfill. The file for this site did not contain any other significant information regarding the UST removal or soil remediation. .e Based on the available documentation, it is unlikely that petroleum contamination from the K&N Meats site will affect soils in the project corridor. With the exception of one soil sample,remnant soils left in place after overexcavation are `Class 1' or `Class 2' soils as defined by Ecology(2010). These soils may be reused as on-site fill above ground water if structurally suitable,but will require disposal as contaminated if not. 5.1.4 Carwash Enterprises (621 Rainier Avenue South) `L The site is located approximately 500 feet east of the project alignment and is a listed LUST site. The reviewed file did not contain a UST site assessment report or other associated information. The file for this site included an application document to King County Department of Metropolitan Services (Metro) for a wastewater discharge permit (Shannon&Wilson, 1995). The application contained excerpts of a Shannon&Wilson ground water monitoring report and a remedial system pilot test report. According to the ground water monitoring data included in the application, ground water at the site contained gasoline range hydrocarbons and BTEX in exceedance of MTCA cleanup levels in multiple site monitoring wells. According to water level elevations documented in the remedial system pilot test report, ground water flow at the site is to the south, toward Rainer Avenue South. The file did not include other remedial reports or subsequent ground water monitoring reports. Based on the available data, there is the potential for ground water impacts at 2011-044-21 SW 7th Street Final Report April 201417 HWA GEOSCIENCES INC. rr ;k April 15, 2014 HWA Project No. 2011-044-21 SW 7th Street and Rainier Avenue South; however, the site is unlikely to affect the Hardie Ave. SW—SW 7th St. project due to the distance from the project. 5.2 CONCLUSIONS Based on the findings of this study, with the exception of the Black River site, there is a low to moderate potential that subsurface activities (excavation, earthwork, grading and utility work) in the project corridor may encounter soils and ground water that may contain elevated concentrations of petroleum or other contaminants. Although there is insufficient information to delineate potentially contaminated areas on the plans, construction bid documents should include all background information, analytical results and provisions for contaminated soil handling, treatment/disposal, and health and safety requirements. Proposed project improvements (a wet pond) at the Tract B /former Black River site are very likely to encounter contaminated soils, and should be called out on project plans and in the specifications. Construction bid documents should include all background information, analytical results and provisions for contaminated soil handling, treatment/disposal, and health and safety requirements. Proposed stormwater discharge, detention, or conveyance is likely to exacerbate or disturb the contamination, as well as trigger regulatory scrutiny. Project design should be re-evaluated with respect to contamination issues in this area. Additional exploration and sampling should be performed at the Tract B / former Black River site in areas proposed for new construction, to evaluate potential cleanup costs and construction impacts. a Additional explorations are also recommended in the channel between Naches and Powell streets, if this area is slated for excavation or channel modifications. This channel is directly upstream of, and feeds into Tract B / Black River site. This area has not previously been sampled, and may be impacted if stormwater was the source of impacts at the Black River site. 5.3 GENERAL RECOMMENDATIONS 5.3.1 Construction Issues Construction bid documents (plans and specifications) should include all available analytical results and provisions for contaminated soil and waste handling, treatment/disposal, and health and safety requirements. Subsurface work in the vicinity of reported release locations should account for field screening during excavation and segregation and analytical testing of suspected contaminated soils and ground water, if encountered. If impacted soils are discovered 2011-044-21 SW 7th Street Final Report April 201418 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 during construction, soils should be sampled and analyzed by the owner's representative to limit the volume requiring treatment or disposal and to document the findings. Excavation outside of the utility trenches is not recommended. Several treatment and disposal options for contaminated soils are available, including: • On-site disposal (use as roadway subgrade, or hot batch asphalt incorporation); Off-site landfill disposal at a licensed facility; �w • Off-site thermal treatment and disposal/recycling at a licensed facility. Costs to excavate, haul, treat or dispose of petroleum contaminated soils generally range from $40 to $60 a ton. r Net export or unsuitable soil excavated for construction that does not contain contaminants exceeding cleanup levels may still require treatment or disposal at a licensed facility, as many fill sites will not accept soils with detectable concentrations of contaminants. MTCA cleanup levels are used in this report for reference only, and normally apply to soils being excavated for the purpose of remediation. If excavated materials (e.g., "unsuitable" or net export soils) are disposed off-site,property owners at the receiving site should be notified of the results of this study and any additional testing information available at that time. Criteria for unrestricted use of soils may be lower than some cleanup levels. Soils with contaminant concentrations above detection limits but below cleanup levels should not be used as fill near surface or ground water. The contractor should be required to notify the Engineer or Owner's representative of suspected contaminated materials, with provisions in the specifications for assisting the Engineer with excavations for testing, segregating and stockpiling materials, sedimentation and erosion control, dust control, decontamination, and standby time or provisions for delays due to testing. The contractor should be required to submit waste characterization, waste management, spill prevention/control, and health & safety plans which address these issues. HWA recommends sampling and testing for any contractor force account or unit rate pay items (e.g., contaminated soils disposal) be conducted by the Owner's representative. 5.3.2 Ground Water Although no known ground water contamination is documented along the project alignment, it is possible; therefore construction bid documents (plans and specifications) addressing construction dewatering should include all analytical results and provisions for contaminated water testing, storage, treatment/disposal, and health and safety wr requirements. Contaminated water treatment/disposal options may include: 2011-044-21 SW 7th Street Final Report April 201419 HWA GEOSCIENCES INC. April 15, 2014 HWA Project No. 2011-044-21 • Off-site treatment and disposal; • On-site treatment and discharge; • Discharge to sanitary sewer under permit. These measures may be handled as force account or unit rate (per gallon,but with no minimum guarantee)bid items. If ground water is encountered which is suspected of being contaminated based on visual, odor, or other characteristics or information, sump pumping or dewatering discharge should be stored on site and tested to determine treatment/disposal options. Off-site disposal typically is feasible for small quantities of water(<10,000 gallons). Short-term discharge to sanitary sewer under permit would likely be permitted depending on the water quality. 5.3.3 Health and Safety HWA recommends that appropriate health and safety measures be taken during excavation in areas where refuse, contaminated soils, ground water, or vapors may be ifr present. These measures may include,but are not limited to,preparation of a site specific health and safety plan, air monitoring, site control/access,protective and decontamination measures, worker training, certification, and medical monitoring. We recommend an industrial hygienist or health and safety specialist be consulted to determine the applicability of these requirements. Construction specifications should include all available analytical results including this and other available reports. 6.0 CONDITIONS AND LIMITATIONS We have prepared this report for Leidos and the City of Renton for use in design of a portion of this project. This report should be provided in its entirety to prospective contractors for bidding and estimating purposes; however, the conclusions and interpretations presented in this report should not be construed as a warranty of the subsurface conditions. Experience has shown that soil and ground water conditions can vary significantly over small distances. Inconsistent conditions can occur between explorations and may not be detected by a geotechnical study. If, during future site operations, subsurface conditions are encountered which vary appreciably from those described herein, HWA should be notified for review of the recommendations of this report, and revision of such if necessary. Sufficient geotechnical monitoring, testing, and consultation by HWA GeoSciences, Inc., should be provided during construction to confirm that the conditions encountered are 2011-044-21 SW 7th Street Final Report April 201420 HWA GEOSCIENCES INC. to April 15, 2014 HWA Project No. 2011-044-21 ow consistent with those indicated by the explorations, to provide recommendations for design changes should conditions revealed during construction differ from those w anticipated, and to verify that the geotechnical aspects of construction comply with the contract plans and specifications. Within the limitations of scope, schedule and budget, HWA attempted to execute these services in accordance with generally accepted professional principles and practices in the fields of geotechnical engineering and engineering geology in the area at the time the wr report was prepared. No warranty, express or implied, is made. The scope of our work did not include decommissioning of monitoring wells installed for this project. r. This firm does not practice or consult in the field of safety engineering. We do not direct the contractor's operations, and cannot be responsible for the safety of personnel other than our own on the site. As such, the safety of others is the responsibility of the contractor.

File: 001159 1 2651211024 Leidos Engineering,LLC 1-5 +wr Section 1 This preliminary SWPPP document was prepared for local permit and the NPDES w permit applications. Following award of the contract, the Contractor is required to prepare a more detailed SWPPP prior to construction that reflects the actual schedule, techniques, and work approaches to be utilized by the Contractor. The Contractor's SWPPP must meet all permit requirments. rr to wrw 1-6 Leidos Engineering,LLC Hardie Ave SW7a,SWPPP 11-08-2013.docx it Section 2 SITE DESCRIPTION - EXISTING AND PROPOSED Existing Site The existing SW 7th Street storm drainage system is a major trunk line draining 623 acres of the South Renton Subbasin, which includes much of the downtown area. 1r The existing pipe system generally consists of 48-inch to 60-inch diameter pipe that extends west along SW 7th Street and then north along Naches Ave SW to discharge to an unnamed stream (defined as Stream A in the critical areas study [Stream Study, Herrera, 2013]. This stream drains to the Black River Pump Station forebay, an area which designated by the City of Renton as Shoreline jurisdiction. The project mainly consists of a 60-inch diameter parallel pipe installation along SW 7th Street from Lind Ave SW to Naches Ave SW, and then along Naches Ave SW to the outfall to Stream A. Water quality treatment using Filterra media system vaults will be installed only along SW 7th Street from Lind Ave SW to Naches Ave SW. Ground elevations range between 20 to 25 feet within the extent of the project. Land use is business commercial with predominantly business park-type buildings, parking lots and landscaping. Exceptions to this general site character are the City- owned wetlands to the west of the Naches Ave SW between SW 7th Street and the outfall of the existing and proposed parallel pipe. r The existing drainage system consists of curb and gutter, inlets and connections to the existing 60-inch diameter pipe that discharges to Stream A. Utilities along the project alignment include water, sanitary sewer, storm drain, fiber optic communications, cable, gas, and power(above and below ground). Any of these r utilities that are in conflict with the proposed trunk line will be relocated. Vegetation and Critical Areas Most of the corridor along the project consist of paved public road with some grass median and in between curbs and sidewalks. Critical areas were investigated as part of the permit acquisition for the project. They include an unnamed stream (defined as Stream A in the critical areas study [Stream Study, Herrera, 20131 that the proposed pipeline will discharge to and two wetlands located west of Naches Ave SW between SW 7th Street and the proposed outfall. The wetlands were identified in the Wetland �. Assessment Report and Buffer Mitigation Plan [(Herrera, 2013]. The wetlands are a minimum of about 75 feet west of Naches Ave SW, with a vegetated wetland buffer between. Soils A geotechnical report, entitled Geotechnical Engineering Report - SW 7th Street / Naches Ave SW Storm System Improvement Project [HWA GeoSciences, 2013] was prepared for the project ([Month] 2011). Field explorations in the project area and .r File: 0011591 2651211024 l idol 11111 Section 2 laboratory testing revealed that fill soils to depths of 2.5 to 7.5 feet. Recent alluvium +r deposited below the fill is defined as Alluvial Silts and Sands in boring logs and described as fine grained and deposited in relatively low energy environments such as a lake or estuary. Proposed Construction Activities and Project Description The purpose of this project is to construct a parallel storm drain in the lower portion of 4 the basin to increase overall system capacity and help alleviate upstream floodin problems. The project includes stormwater treatment retrofitting along SW 7t between Naches Ave SW and Lind Avenue SW. The City applied for and obtained a grant from the Washington State Department of Ecology for water quality retrofits along SW 7th Street. SW 7th Street is a busy arterial with high truck traffic and the water quality retrofit will be a significant water quality improvement to the downstream system and Stream A. Treatment will be provided by installing between 15 and 20 Filterra systems. Filterra system utilizes a media blend designed to remove typical stormwater pollutants such as TSS, phosphorus, nitrogen, heavy metals, and oil and grease. Typical size of Filterra units will be between 4-ft x 4-ft to 6-ft x 4-ft. The Filterra systems will be designed and installed in accordance with the Conditions of Use listed in the General Use Level Designation for the Filterra System and manufacturer specifications. The project will include upgrades of the storm drainage laterals to connect the new Filterra units to the existing or new trunk storm drain. Construction activities will include: • Excavation and trenching to install the new trunk, manholes, catch basins and lateral pipes and providing required shoring. • Constructing a new outfall to Stream A including replacing or adding new rock lining to the existing channel bank(which is currently rock lined) • Installation of new Filterra units along roadway and lateral connections to either the existing system or new 60-inch storm drain. • Excavation and trenching to relocate water and sewer lines where they are in conflict with the new storm trunk. • Pavement overlay and pavement repair where required on the contract drawings. ► • Removing or abandoning water lines and storm sewers where required on the contract drawings. • Protection of existing underground utilities where they cross or are in close proximity to the trenching and excavation work. • Restoration of street lights, sidewalks, curbs and gutters as required by the contract drawings and specifications. • Seeding, fertilizing and mulching in the vegetated area near the outfall to stream rn A. wr 2-2 Leidos Engineering,LLC Hardie Ave sw7th swrrr t t-os-2ot3.docx SITE DESCRIPTION - EXISTING AND PROPOSED ,,, ■ Removing trees and protecting others as required by the contract drawings and specifications.

This section provides a detailed description of the BMPs to be implemented based on r„ the 12 required elements of the SWPPP. In addition to describing the purpose of the 12 required elements in turn, this section also includes a list of the BMPs that are anticipated to be implemented to satisfy the element at the project site. "' Note that the Contractor may modify these lists when preparing the Contractor's SWPPP, which will be submitted for approval prior to construction. The 12 BMP Elements BMP Element#1 -Mark Clearing Limits To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of construction for all non-roadway areas will be clearly marked before .r land-disturbing activities begin. Trees that are to be preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the field and on the plans. In general, natural vegetation and native topsoil shall be retained in an undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing limits that will be applied for this project include: +� ■ Preserving Natural Vegetation ii High Visibility Plastic or Metal Fence BMP Element#2 - Establish Construction Access Construction access or activities occurring on unpaved areas shall be minimized. If necessary, the access point to new outfall shall be stabilized to minimize the tracking of sediment onto public roads, and street sweeping and street cleaning shall be employed to prevent sediment from entering state waters. The BMPs relevant to establishing construction access that will be applied for this project include: ■ Street Sweeping +.� Only essential equipment should be allowed in disturbed areas on the site, and loose sediment shall be cleaned from all equipment prior to leaving the site. Routine street sweeping will be used to prevent the off-site transport of sediment. The frequency of street sweeping will depend on the quantity of expected construction traffic. •r+ Often, excavation of the existing soils for installation of pipe will be performed from the existing paved surfaces or roadway shoulders. Import and haul of material will also use the existing paved surface. The pavement will be swept when needed as directed by the CESCL or engineer. File: 001159 1 2651211024 l idol Section 3 go BMP Element#3- Control Flow Rates No detention is planned for this project because there are no new impervious surfaces. Surface water will be controlled using a temporary stormwater bypasses for Stream A and other pipe drainages. The stream bypass is design shall be designed to convey the 10-year peak flow (during the construction window). BMP Element#4- Install Sediment Controls All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal BMP before leaving the construction area. The BMPs relevant to installing sediment controls that will be applied for this project include: • Silt Fence r • Straw Mulch • Catch Basin Inserts (Inlet Protection) ,rr In addition, sediment will be removed from paved areas in and adjacent to construction work areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on vehicle tires away from the site and to minimize washoff of sediments from adjacent streets in runoff. Sediment-laden water shall not be discharged in on-site, relatively level, vegetated areas unless approved by the City of Renton. BMP Element#5- Stabilize Soils wr Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent erosion throughout the life of the project. The BMPs relevant to stabilizing soils that will be applied to this project include: • Temporary and Permanent Seeding • Mulching • Plastic Covering In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be temporarily covered with plastic sheeting. Permanent cover measures shall be installed as soon as possible after areas of construction are completed. All stockpiled soils shall be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels. BMP Element#6- Protect Slopes With the exception of the outfall to Stream A, there are no steep slopes. The channel side slopes at the proposed Stream A outfall are already rock-lined. The rock-lining + ► will be restored after the outfall construction. 3-2 Leidos Engineering,LLC Hardie Ave SW7th SWPPP 11-08-2013.docx CONSTRUCTION STORMWATER BMPS to.. BMP Element#7- Protect Drain Inlets All storm drain inlets, catch basins, and culverts made operable during construction shall be protected to prevent unfiltered or untreated water from entering the drainage conveyance system. However, the first priority is to keep all access roads clean of sediment and keep street wash water separate from entering storm drains until treatment can be provided. Catch Basin Inserts will be implemented for all drainage inlets, catch basins, and culverts that could potentially be impacted by sediment-laden runoff on and near the construction area (downslope and within 500 feet of the construction limits). The BMPs relevant to protecting drain inlets that will be applied to this project include: ■ Catch Basin Inserts (Inlet Protection) Appropriate inlet protection BMPs will be installed, maintained and interchanged to accommodate different needs and situations with the phasing and construction activities taking place near each catch basin or inlet on the site and within 500 feet of ow the construction limits. Any filter fabric or "socks" installed in publicly owned and maintained inlets will be the Contractor's responsibility to install, inspect, and maintain. Maintenance and inspection is especially important during rain events where flow restrictions in these inlets could cause runoff to bypass the inlets and cause problems downstream of the site. BMP Element#8- Stabilize Channels and Outlets With the exception of the outfall to Stream A, there are no channels. The channel rr► bottom and side slopes at the proposed Stream A outfall are already rock-lined. The rock-lining will be restored after the outfall construction. BMP Element#9-Control Pollutants All pollutants, including waste materials and demolition debris, that occur on-site shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well-organized, and free of debris. The BMPs relevant to controlling pollutants that will be applied to this project include: • Vehicles, construction equipment, and/or petroleum product storing/dispensing: - All vehicles, equipment, and petroleum product storage/dispensing will be inspected regularly to detect any leaks or spills, and to identify maintenance needs to prevent leaks or spills. ,.. - Spill prevention measures, such as drip pans, will be used when conducting maintenance and repair of vehicles or equipment. - Contaminated surfaces shall be cleaned immediately following any discharge or spill incident. • Chemical storage: w. File: 001159 1 2651211024 Leidos Engineering,LLC 3-3 Section 3 „ — Any chemicals stored in the construction areas will conform to the appropriate rrr source control BMPs. All chemicals shall have cover, containment, and protection provided on-site. — Application of agricultural chemicals, including fertilizers and pesticides, shall be conducted in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Manufacturers' recommendations for application procedures and rates shall be followed. • Excavation spoils dewatering waste: — Dewatering BMPs and BMPs specific to the excavation (including handling of ' contaminated soils) are discussed under Element 10. • Demolition: rr — Dust released from demolished sidewalks, buildings, or structures will be controlled using Dust Control Measures. rr — Storm drain inlets vulnerable to stormwater discharge carrying dust, soil, or debris will be protected using Storm Drain Inlet Protection (as described above for Element 7 as catch basin inserts). — Process water and slurry resulting from sawcutting and surfacing operations will be prevented from entering the waters of the State by implementing Sawcutting and Surfacing Pollution Prevention measures. • Concrete and grout: — Process water and slurry resulting from concrete work will be prevented from entering the waters of the State by implementing Concrete Handling measures. • Sanitary wastewater: — Portable sanitation facilities will be firmly secured, regularly maintained, and emptied when necessary. • Solid Waste: — Solid waste will be stored in secure, clearly marked containers. • Other: — Other BMPs will be administered as necessary to address any additional pollutant sources on-site. — No discharges to the sanitary sewer system are allowed without prior approval from King County Industrial Waste and City of Renton . BMP Element#10—Control Dewatering All dewatering water and runoff within the construction area shall meet all local, state ► and federal requirements for water quality prior to discharge into receiving water bodies. Excavation and trench dewatering water shall be discharged into a controlled conveyance system (such as pumping or piping) prior to discharge to a temporary .r sediment pond or portable treatment tank if it does not meet water quality standards. 3-4 Leidos Engineering,LLC Hardie Ave SW7th SWPPP 11-08-2013.docx Wo CONSTRUCTION STORMWATER BMPS we Conveyance systems to transport this water shall be designed by a professional engineer. Clean, non-turbid dewatering water such as well-point groundwater may be discharged to systems tributary to state surface waters, provided that this dewatering ww, water meets water quality discharge requirements and does not cause erosion or flooding of receiving waters. These clean waters should not be routed through stormwater sediment ponds or portable treatment tanks. Highly turbid or contaminated dewatering water from construction equipment operation, open trenches or work inside a cofferdam will require additional monitoring and will be treated separately from stormwater. Such monitoring is the responsibility of the Contractor. The BMPs relevant to controlling dewatering that will be applied to this project include: ■ Onsite Filtration through approved vegetated areas ■ Portable Filtration System ■ Discharge to sanitary sewer system after meeting pretreatment requirements and obtaining applicable permits BMP Element#11 - Maintain BMPs All temporary and permanent erosion and sediment control BMPs shall be maintained and repaired as needed to assure continued performance of their intended function. " Maintenance and repair shall be conducted in accordance with each particular BMP's specifications. Visual monitoring of the BMPs will be conducted at least once every calendar week and within 24 hours of any rainfall event that causes a discharge from the site. If the site becomes inactive, and is temporarily stabilized, the inspection frequency will be reduced to once every month. All temporary erosion and sediment control BMPs shall be removed within 30 days after the final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized on-site. Disturbed soil �.. resulting from removal of BMPs or vegetation shall be permanently stabilized. BMP Element#12-Manage the Project Erosion and sediment control BMPs for this project have been designed based on the following principles: ■ Design the project to fit the existing topography, soils, and drainage patterns. ■ Emphasize erosion control rather than sediment control. ■ Minimize the extent and duration of the area exposed. ■ Retain sediment on-site. ■ Thoroughly monitor site and maintain as ESC measures. ■ Schedule major earthwork during the dry season. As this project site is located west of the Cascade Mountain Crest, the project will be managed according to the following key project components: ww File: 001159 1 2651211024 Leidos Engineering,LLC 3-5 err Section 3 • Phasing of construction am — The construction project is being phased to the extent practicable in order to prevent soil erosion, and, to the maximum extent possible, the transport of sediment from the site during construction. — Revegetation of exposed areas and maintenance of that vegetation shall be an integral part of the clearing activities during each phase of construction, per the Scheduling BMP. • Seasonal Work Limitations — From November 1 through April 30, clearing, grading, and other soil disturbing activities shall only be permitted if shown to the satisfaction of the local permitting authority that sediment-laden runoff will be prevented from leaving the site through a combination of the following: • Site conditions including existing vegetative coverage, slope, soil type, and proximity to receiving waters; and • Limitations on activities and the extent of disturbed areas; and • Proposed erosion and sediment control measures. 4 — Based on the information provided and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on-site disturbance. — The following activities are exempt from the seasonal clearing and grading limitations: • Routine maintenance and necessary repair or erosion and sediment control BMPs; as • Routine maintenance of public facilities or existing utility structures that do no expose the soil or result in the removal of the vegetative cover to soil; and • Activities where there is 100 percent infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities. • Coordination with Utilities and Other Jurisdictions — Contractor shall coordinate with utilities, other construction projects, and the local jurisdiction in preparing this SWPPP and scheduling the construction work. • Inspection and Monitoring — All BMPs shall be inspected, maintained, and repaired as needed to assure continued performance of their intended function. Site inspections shall be conducted by a person who is knowledgeable in the principles and practices of sediment and erosion control. This person has the necessary skills to: 3-6 Leidos Engineering,LLC Hardie Ave sw7th swrrr 11-08-2013.docx No CONSTRUCTION STORMWATER BMPS .. Assess the site conditions and construction activities that could impact the quality of stormwater, and ■ Assess the effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. • A Certified Erosion and Sediment Control Lead shall be on-site or on-call at all times. • Whenever inspection and/or monitoring reveals that the BMPs identified in this SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMPs or design changes shall be implemented as soon as possible. ■ Maintaining and Updated Construction SWPPP — This SWPPP shall be retained on-site or within reasonable access to the site. — The SWPPP shall be modified whenever there is a change in the design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect of the discharge of pollutants to waters of the ow State. — The SWPPP shall be modified if, during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory NA authority, it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The SWPPP shall be modified as necessary to include any additional or ■` modified BMPs designed to correct problems identified. Revisions to the SWPPP shall be completed within seven (7) days following the inspection. Site-Specific Erosion and Sediment Control BMPs ,,,■ Site specific BMPs are shown in the TESC plan sheets and notes within the Contract Drawings. General ESC notes are shown on Contract Drawing Sheet G3. Additional notes and details are shown on Contract Drawing Sheet G4. These TESC drawings are included in Appendix A. These plans will be updated as necessary during construction including addition of any additional BMPs to be used on the project site that are not shown on the conceptual layout. This section includes brief descriptions of the implementation and use of the site-specific BMPs that are anticipated for this project. ,. A silt fence will be placed around entire staging/stockpiling areas per City of Renton Standard Plan 214. BMPs will be implemented as shown on the Contract Drawings and as indicated in the Contract Documents. Alternate BMPs will be required in the event the BMP(s) described above are deemed ineffective or inappropriate during construction to satisfy the requirements as set forth in the NPDES General Permit. To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater Permit, the Certified Erosion and Sediment Control Lead Fite: 001159 1 2651211024 Leidos Engineering,LLC 3-7 ■r Section 3 (CESCL) will promptly initiate the implementation of one or more alternative BMPs after the first sign that the existing BMPs are ineffective or failing. Engineering Calculations for TESC BMP Sizing A temporary 48-inch pipe would be needed to bypass flows in Stream A. This bypass pipe was sized based on the 10-year peak flow obtained using a frequency analysis of 60 years of peak annual construction season flows generated from a one-hour time step HSPF model. The peak annual construction season flows were peak flows in the dry season from July 1 to August 31. Once the peak flows were determined, frequency Ilk flows were determined using a Log-Pearson Type III statistical analysis. Once the bypass design flows were determined using the above, the bypass pipe was sized using standard culvert capacity nomograph for inlet controlled conditions with a +w► grooved end and headwall type of entrance. Non-ESC BMPs Required Pesticide Control No chemical herbicides will be allowed in seeding areas unless otherwise directed by the Engineer. r�l Equipment Washing Washout from a concrete trucks should be disposed of into a designated area which will later be backfilled or where the concrete wash can harden, be broken up, and then hauled for disposal at a location which is not subject to surface water runoff, and more than 100 feet away from a storm drain, open ditch, or receiving water. Petroleum and Chemical Products All vehicle maintenance and fueling shall be performed in areas that are located away from drainage courses. Petroleum and chemical products shall be stored in locked weather resistant sheds that are located away from drainage courses. The sheds shall be monitored regularly for leaks and repaired as necessary. Workers shall be instructed in proper storage and A handling of materials. Information for procedures in case of spills shall be provided by the Contractor. The Contractor shall have persons trained in handling spills and shall be on-site or on-call at all times. Materials for cleaning spills shall be kept on-site and easily available. Spills should be cleaned up immediately and the contaminated material disposed of properly. Nutrient Application and Control Great care shall be taken to keep fertilizers out of waterways. Fertilizers shall be phosphorus free where specified on the drawings. err 3-8 Leidos Engineering,LLC Hardie Ave sw7rh swPPP 11-08-2013.aocx lot up CONSTRUCTION STORMWATER BMPS Solid Waste Handling and Disposal Adequate disposal facilities in clearly labeled waste containers shall be provided in covered areas until solid waste can be removed and disposed of at a pre-approved disposal site. Lids should be kept closed at all times. Solid waste caught in erosion and sediment control structures shall be removed on a regular basis. Dust Control Precautions shall be taken to minimize the generation and release of dust into the air. The Contractor shall employ the following best management practices: • Use water trucks to prevent the generation of fugitive particulate (dust). Water should be added before and immediately (within fifteen to thirty minutes) after the soil is disturbed without using excessive amounts of water. ■ Stage activities so that natural vegetation remains undisturbed as long as possible. • Place high and low pressure fogging nozzles at the point of generation to knock down particulates before they can be released to the ambient air. • Cover stockpiles and disturbed soils with temporary cover measures. • Cover haul trucks to reduce the amount of dust blown from the trailer compartment during transport. • Provide additional vacuum-type street sweeping to that necessary for erosion and sediment control. • Provide additional dust control measures on the construction site to protect adjacent residential properties from fugitive dust. • Additional site-specific dust control measures may be required. aw go we ows wr File: 001159 1 2651211024 Leidos Engineering,LLC 3-9 to iW N Section 4 CONSTRUCTION PHASING, SCHEDULE, AND BMP me IMPLEMENTATION " The Contractor will determine project phasing, sequencing, and schedules in accordance with the requirements of the Contract Documents.

A site log book will be maintained for all on-site construction activities and will include: "" ■ A record of the implementation of the SWPPP and other permit requirements; ■ Site inspections; and, so ■ Stormwater quality monitoring. For convenience, the inspection form and water quality monitoring forms included in ,W this SWPPP include the required information for the site log book. This SWPPP may function as the site log book if desired, or the forms may be separated and included in a separate site log book. However, if separated, the site log book but must be VW maintained on-site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction. Site Inspection All BMPs will be inspected, maintained, and repaired as needed to assure continued performance of their intended function. The inspector will be a Certified Erosion and Sediment Control Lead(CESCL). The name and contact information for the CESCL is provided in Section 5 of this SWPPP. Site inspection will occur in all areas disturbed by construction activities and at all stormwater discharge points. Stormwatei will be examined for the presence of suspended sediment, turbidity, discoloration, and oily sheen. The site inspector will evaluate and document the effectiveness of the installed BMPs and determine if it is necessary to repair or replace any of the BMPs to improve the quality of stormwater discharges. All maintenance and repairs will be documented in the site log book or forms provided in this document. All new BMPs or design changes will be documented in the SWPPP as soon as possible. r Site Inspection Frequency Site inspections will be conducted at least once a week and within 24 hours following any rainfall event which causes a discharge of stormwater from the site. For sites with temporary stabilization measures, the site inspection frequency can be reduced to once every month. Site Inspection Documentation The site inspector will record each site inspection using the site log inspection forms provided in Appendix B. The site inspection log forms may be separated from this r File: 001159 1 2651211024 Ieidos Section 6 SWPPP document, but will be maintained on-site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction. Stormwater Quality Monitoring Turbidity Sampling Monitoring requirements for the proposed project will include either turbidity or water transparency sampling to monitor site discharges for water quality. Sampling will be conducted at the discharge point at least once per calendar week. Turbidity or transparency monitoring will follow the accepted analytical methodologies. The key benchmark values that require action are 25 NTU for turbidity (equivalent to 32 cm transparency) and 250 NTU for turbidity (equivalent to 6 cm transparency). If the 25 NTU benchmark for turbidity (equivalent to 32 cm transparency) is exceeded, the following steps will be conducted: I. Ensure all BMPs specified in this SWPPP are installed and functioning as intended. 2. Assess whether additional BMPs should be implemented, and document revisions to the SWPPP as necessary. 3. Sample discharge location daily until the analysis results are less than 25 NTU (turbidity) or greater than 32 cm(transparency). If the turbidity is greater than 25 NTU (or transparency is less than 32 cm) but less than 250 NTU (transparency greater than 6 cm) for more than 3 days, additional treatment BMPs will be implemented within 24 hours of the third consecutive sample that exceeded the benchmark value. Additional treatment BMPs to be considered will include, but are not limited to, off-site treatment, infiltration, filtration and chemical treatment. If the 250 NTU benchmark for turbidity (or less than 6 cm transparency) is exceeded at any time, the following steps will be conducted: 1. Notify Ecology by phone within 24 hours of analysis (see Section 2.5 of this lit SWPPP for contact information). 2. Continue daily sampling until the turbidity is less than 25 NTU (or transparency is greater than 32 cm). 3. Initiate additional treatment BMPs such as off-site treatment, infiltration, filtration, and chemical treatment within 24 hours of the first 250 NTU exceedance. lit 4. Implement additional treatment BMPs as soon as possible, but within 7 days of the first 250 NTU exceedance. 5. Describe inspection results and remedial actions taken in the site log book and in monthly discharge monitoring reports as described in Section 2.7 of this SWPPP. 6-2 Leidos Engineering,LLC Hardie Ave SW7th SWPPP 11-08-2013.docx SITE INSPECTIONS AND MONITORING pH Sampling Sampling and monitoring for pH will occur during construction. Samples will be collected weekly at the temporary storage and treatment system prior to discharge to surface water. Samples will be analyzed for pH using a calibrated pH meter and recorded in the site log book. tw The key benchmark pH value for stormwater is a maximum of 8.0. If a pH greater than 8.0 is measured in the temporary storage and treatment system that has the potential to discharge to surface water, the following steps will be conducted: 1. Assess whether additional BMPs should be implemented and whether associated revisions to the SWPPP are necessary ,■, 2. Stop (detain) all discharges from leaving the site and entering surface waters or storm drains if the pH is greater than 8.5 3. Sample temporary storage and treatment system the following day, and if the pH exceeds 8.0 for the second consecutive day, implement CO2 sparging treatment 4. Sample and measure pH daily until there are 3 consecutive pH measurements less than 8.0. 5. If there are 3 consecutive pH measurements greater than 8.0, notify Ecology by phone within 24 hours of the 3rd measurement exceeding a pH of 8.0 (see Section 2.5 of this SWPPP for contact information) and initiate discussions with Ecology regarding additional treatment BMPs. aw 6. Describe inspection results and remedial actions that are taken in the site log book and in monthly discharge monitoring reports as described in Section 2.7 of this SWPPP. Monitoring includes visual inspection and documentation of the inspection in a site log book. A site log book will be maintained for all on-site construction activities and will include: • A record of the implementation of the SWPPP and other permit requirements, and; • Site inspections. ww For convenience, the inspection form included in this SWPPP includes the required information for the site log book. This SWPPP may function as the site log book if desired, or the forms may be separated and included in a separate site log book.

File: 001159 1 2651211024 Leidos Engineering,LLC 6-3 irr Section 7 RECORDKEEPING AND REPORTING iW Recordkeeping A site log book will be maintained for all on-site construction activities and will include: • A record of the implementation of the SWPPP and other permit requirements; • Site inspections; and, • Stormwater quality monitoring. Records of all monitoring information (site log book, inspection reports/checklists, .r► etc.), this SWPPP, and any other documentation of compliance with permit requirements will be retained during the life of the construction project. The SWPPP and Site Log Book will be retained on-site or within reasonable access to the site and will be made immediately available upon request to Ecology or the local jurisdiction. A copy of this SWPPP will be provided to Ecology within 14 days of receipt of a written request for the SWPPP from Ecology. Any other information requested by Ecology will be submitted within a reasonable time. This SWPPP will be modified if the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site or there has been a change in design, construction, operation, or maintenance at the site that has a significant effect on the discharge, or potential for discharge, of pollutants to the waters of the State. The SWPPP will be modified within seven days of determination based on inspection(s) that additional or modified BMPs are necessary to correct problems identified, and an updated timeline for BMP implementation will be "" prepared. VM Reporting Water quality sampling results will be retained for review by the City or Ecology. If there is a discharge to the stormwater system that exceeds the pH or the turbidity thresholds outlined in Section 6, then the City and Ecology are to be notified within 24 hours. The City and the Ecology regional office will be notified if chemical treatment other than CO2 sparging is planned for adjustment of high pH water (see Section 5 of this SWPPP for contact information). ■w 1..

As part of planning for proposed construction,the City retained SWCA Environmental Consultants(SWCA),to prepare this Cultural Resources Monitoring and Discovery Plan for the project. This plan provides protocols for monitoring, recording, and reporting any archaeological findings. Monitoring will focus on excavations which have the potential to encounter significant cultural resources. This monitoring plan is intended to help avoid adverse effects to historic, and pre-contact cultural, and archaeological resources that could potentially be affected by construction of this project. The plan provides procedures to reasonably ensure that any cultural resources or human remains that might be encountered are properly identified and appropriately treated in accordance with state and federal law. Project Location and Description The SW 7th Street/Naches Avenue SW Storm System Improvement Project(the Project) is in Section 18 of T. 23N, R. 5E, and Section 13 of T. 23N, R.4E,Willamette Meridian (Figure 1). The SW 7th Street VW drainage system is a major trunk line draining 623 acres of the South Renton Subbasin that drains into the Black River Pump Station forebay(SAIC 2012). The Project will improve conveyance capacity in the lower SW 7th Street trunk drainage storm water system. In particular,the Project will improve 3,300 linear feet of storm system pipe in SW 7th Street from Lind Avenue SW to its outfall at Naches Avenue S to reduce upstream flooding along SW 7th Street. Potential future improvements at the east end of the project include 1,200 linear feet of storm system pipe between Hardie Avenue SW and SW 7th Street to .. reduce flooding at Hardie Avenue SW(Figure 2). Three sewer alignment alternatives were reviewed as part of preliminary engineering for the Project (SAIC 2012). The review consisted of a field survey, utility locating, preliminary geotechnical investigations, preliminary environmental evaluations, and hydrologic and hydraulic modeling. Based primarily on cost effectiveness and lowest environmental impacts, SAIC's preliminary design memorandum recommended Alternative 1A as the preferred solution. Alternative 1A includes a 5 ft. diameter parallel pipe along the entire alignment from the outfall at Naches Avenue SW and along SW 7th Street to just east of Lind Avenue SW. Potential future improvements on private property between SW 7th Street and Hardie Avenue SW include replacement of an existing pipe with a 5 ft. diameter pipe. The City will also install a water quality treatment system along SW 7th Street between Naches Avenue SW and Lind Avenue SW for Alternative 1A. Other potential future improvements include a box culvert ,., and small pump station at a low elevation point on Hardie Avenue. Regulatory Context ow Section 404 of the Clean Water Act (CWA) applies to this Project because of construction work within wetland and streams. The U.S.Army Corps of Engineers(USACE) administers the permitting program under Section 404 of the CWA. In Washington State, applications for CWA Section 404 permits are to accomplished through submittal of a Joint Aquatic Resources Permit Application (DARPA) to the USACE. The project is therefore subject to Section 106 of the National Historic Preservation Act of 1966 (NHPA), as amended, which requires federally assisted, regulated, or permitted undertakings to take into "" account the effects of those undertakings on historic properties included in or eligible for the National Register of Historic Places. No The project is also subject to several Washington state laws pertaining to archaeological cultural resources. For example,the Archaeological Sites and Resources Act [RCW 27.53] prohibits knowingly nr SWCA/Northwest Archaeological Associates 1 May 16, 2013 CONTAINS CONFIDENTIAL INFORMATION NOT FOR GENERAL DISTRIBUTION ow 2 Monitoring and Discovery Plan for the SW 7th Street/Naches Avenue Storm System Improvement Project excavating or disturbing prehistoric and historic archaeological sites on public or private land.The Indian ,r Graves and Records Act [RCW 27.44] prohibits knowingly destroying American Indian graves and provides that inadvertent disturbance through construction or other activities requires re-interment under supervision of the appropriate Indian tribe. In order to prevent the looting or depredation of sites, any maps, records,or other information identifying the location of archaeological sites, historic sites,artifacts, or the site of traditional ceremonial,or social uses and activities of Indian Tribes are also exempt from disclosure [RCW 42.56.300]. Natural and Cultural Setting Prior to Euroamerican development in the early 20'"century,the project was a rich, riverine ecosystem with adjacent marshes and tributary streams with abundant plant and animal resources important to Native American subsistence. The project is adjacent to and crosses the former Black River—the historic outlet channel of Lake Washington and the Cedar River. The Black River was an anadromous fish stream so and an important transportation corridor for the Duwamish,who lived in villages throughout most of present-day Renton and Seattle and along the Duwamish, Black,Green, and Cedar River watersheds and along Lake Washington, Lake Union and Elliot Bay(Suttles and Lane 1990; Ruby and Brown 1992). so The Duwamish people inhabiting the Renton vicinity were known as the Lake Fork Duwamish,who at the time of Euroamerican contact, lived in three primary settlements (Harrington 1909; Waterman ca. , 1920; Smith 1940).The principal Duwamish settlement was located along the Black River adjacent to, and possibly within the current project area. The settlement consisted of two house sites, Sba'badi'd meaning"little mountain," or"crags"for the adjacent sandstone cliffs, and TuxudidU3 meaning "little Cedar River" for Talbot Creek that entered the Black River somewhere near the eastern half of the project area. A second settlement,sko-AHl-ko, meaning "meeting of two rivers,"was located just over a mile west at the confluence of the Green and Black rivers. The third principal settlement was located a half-mile northeast at the former confluence of the Cedar and Black rivers. Ten archaeological sites have been previously recorded within one-half mile of the project. The ethnohistoric-period village of Sba'badi'd(45KI51) is adjacent to the north end of the project and was excavated by archaeologists in 1979 and 1980(Chatters 1981). The site contained a proto-historic assemblage of traditional artifacts composed of flaked and ground-stone tools, modified bone and antler tools, and early historic trade items. A pre-contact period settlement, Tuoldod Altu(45K159) is located several hundred feet north of the mid-project alignment. The site was excavated by archaeologists in the early 1980s and showed the settlement was occupied between approximately 1,765 BP(years Before Present) and 1360 BP (Chatters et al. 1990).The archaeological deposit was composed of a thick, charcoal-rich cultural midden containing numerous fire-hearth and structural features,flaked-and ground-stone tools and other items made of stone, bone and antler. rrr Potential for Archaeological Discovery The previous section demonstrates the rich natural and cultural setting and the high potential for go significant archaeological deposits within the project corridor. Because of this, SWCA recommended archaeological monitoring during construction. This includes any pre-construction activities such as bore-hole excavations or mechanical potholing. The discovery of archaeological deposits during a* construction can lead to significant delays in the area of discovery. The construction contractor is encouraged to develop contingencies for such an event. SWCA/Northwest Archaeological Associates May 16, 2013 CONTAINS CONFIDENTIAL INFORMATION NOT FOR GENERAL DISTRIBUTION i.r Monitoring and Discovery Plan for the SW 7 h Street/Naches Avenue Storm System Improvement Project 3 MONITORING AND DISCOVERY PLAN This monitoring plan describes the policies, procedures and chain of command to ensure that any cultural resources or human remains encountered during construction are properly identified and appropriately treated. The Appendix to this plan provides contact information for the personnel referenced in the following sections. r Briefing SWCA's Monitoring Supervisor will brief key City and construction personnel on cultural resource issues r prior to construction. The briefing will include information on the legal context of cultural resources protection and on the prehistoric, ethnographic, and historic cultural resources that may be present in the construction area. The primary goal of the pre-construction briefing is to familiarize construction personnel with the procedures to be followed in the event that cultural resources are discovered during construction (see below). Monitoring Procedures sw The archaeological monitor will ensure that every reasonable effort is made to fully document archaeological resources inadvertently discovered during construction. The monitor will be allowed to document the discovery of any pre-contact and significant historical archaeological materials exposed during construction. Monitoring may include examination of excavation side-walls and spoils, if it can be done safely, to identify and record previously undocumented cultural material that may be exposed ..+ during excavation. Typical markers of pre-contact human activity include: fire-modified rock(FMR), animal bone, concentrations of shell,ground and flaked stone tools and flaked stone tool-making debris, burned earth, cordage or fiber, organically stained sediments, charcoal, ash, and exotic rocks and minerals. Typical markers of significant historic-period human activity may include: significant deposits of domestic refuse such as bottles,ceramics and cans, and intact structural remains such as building foundations, boardwalks, or other structural elements. Collection of archaeological materials by employees, construction personnel or others with access to the proiect is prohibited by State law[RCW 27.531. .w Discovery Procedures: Cultural Resources An archaeological monitor will be on site during any excavations with potential to encounter native a, sediments. It is the responsibility of the City of Renton, or designated representative,to notify SWCA of any excavation with potential to encounter native sediments. A minimum of 24 hours advance notice is required to schedule a monitor. The following outlines the steps that will occur if cultural resources are o discovered during construction. In the event of an archaeological discovery,the Monitor will request a pause in construction at the spot where the cultural resources are identified and the following steps will be taken: w 1. The Monitor will a) identify the nature of the discovery, and b) conduct a preliminary evaluation. 2. If the discovery is related to Native American activities, or involves concentrations of historic wr materials,work will halt in the area of discovery and the Monitoring Supervisor will request that rir SWCA/Northwest Archaeological Associates May 16, 2013 CONTAINS CONFIDENTIAL INFORMATION NOT FOR GENERAL DISTRIBUTION wr 4 Monitoring and Discovery Plan for the SW 7th Street/Naches Avenue Storm System Improvement Project + the City of Renton,or designated representative, notify the affected tribes and the Department of Archaeology and Historic Preservation (DAHP). 3. The Monitor will fully document, on standard forms, all pre-contact and historic cultural material. Initial efforts will focus on establishing the nature, provenience, and integrity of any discovery. Documentation methods may include photographs, sketches, scaled drawings, and written descriptions. Samples may be taken for identification of analysis by a specialist. Sufficient time will be granted to evaluate the discovery. 4. The Monitoring Supervisor will ensure that the City of Renton is fully briefed on the discovery. Documentation of the discovery will be assembled and forwarded to the City of Renton. The City will consult with the affected tribes,and DAHP. Project activity will be prohibited within 30 feet of the discovery and may not proceed until the consulting parties have concluded that further activities will not adversely affect the property. If the discovery is considered significant, and cannot be avoided,the City will develop a treatment plan in consultation with the affected tribes and DAHP. 5. A letter report will be submitted to the City of Renton at the conclusion of the project reporting the results of the monitoring. The City will forward the report to the affected tribes and DAHP. Discovery Procedures: Human Remains At the time that any bone that may be human,or any funerary object is discovered, construction activity in the vicinity will cease immediately to allow the Monitor to conduct preliminary analysis to determine if the remains are possibly human. Upon discovery, no additional earth moving or stockpiling of materials will occur within thirty(30)feet and the area of discovery will be avoided. If the remains are determined to be human, or possibly human: no 1. The Monitoring Supervisor will immediately notify the City of Renton. wi 2. Upon receiving notice,the City of Renton, or designated representative, shall immediately notify the City of Renton Police Department and King County Medical Examiner(ME) and request that the ME determine if the remains are forensic or non-forensic. it 3. Contemporaneous with notifying local law enforcement and the ME,the City of Renton will also notify the affected tribes, and DAHP. so 4. If the ME determines the remains are non-forensic, DAHP will take jurisdiction over the remains. 5. The State Physical Anthropologist will make a determination if the remains are Indian or non- go Indian and report that finding to the affected parties. 6. DAHP will handle all consultation with the affected parties as to the future preservation, excavation, and disposition of the remains. 7. SWCA will prepare a final report that describes the discovery, notification of affected parties, steps taken in response to the discovery, and the final disposition of the remains. do SWCA/Northwest Archaeological Associates May 16, 2013 CONTAINS CONFIDENTIAL INFORMATION NOT FOR GENERAL DISTRIBUTION `o Monitoring and Discovery Plan for the SW 7th Street/Naches Avenue Storm System Improvement Project 5 r.

The Contractor's request shall list the specific items of Work in subparagraph two above that remains to be completed in order to reach physical completion. The Engineer may also establish the Substantial Completion Date unilaterally. If after this inspection, the Engineer concurs with the Contractor that the Work is substantially complete and ready for its intended use,the Engineer, by written notice to the Contractor, will set the Substantial Completion Date. If, after this inspection the Engineer does not consider the Work substantially complete and ready for its intended use,the Engineer will, by written notice,so notify the Contractor giving the reasons therefore. Upon receipt of written notice concurring in or denying substantial completion, whichever is applicable, the Contractor shall pursue vigorously, diligently and without unauthorized interruption, the Work necessary to reach Substantial and Physical Completion.

The Contractor shall review and become thoroughly familiar IV with the groundwater conditions and dewatering requirements presented in the Geotechnical Engineering Report, SW 7th Street Drainage Improvement Project, Renton, Washington (HWA GeoSciences, 2014) (hereafter referred to as the Geotechnical Report). The Contractor shall include in its Bid all costs to provide the dewatering facilities sufficient to control groundwater to maintain a dry and firm excavation. As described excavation depths will extend below groundwater. Dewatering will be required. In-trench pumping will likely not be adequate for dewatering. Dewatering will likely require dewatering wells or well points in some or all areas along the trench. In particular, higher ground water flow rates should be expected where the project excavations coincide with the alignment of the former Black River because ground water may preferentially flow in the alluvial sediments in that section of the project.This is in the vicinity of SW 7th Street and Naches Ave SW. Settlement of adjoining ground surface, structures or utilities may occur due to dewatering activities. Dewatering should be performed in such a way as to not cause settlements or damage to adjacent areas. Design and implementation of any dewatering system is the responsibility of the contractor. Dewatering systems should be designed and submitted to the project engineer for approval prior to the commencement of WL the excavation. The Contractor is fully responsible for the cost of all dewatering activities and thus the sequencing of the construction and excavations will be a key component during construction.

Coastal Zone Management Consistency Response for this NWP �r In addition to any special condition that may be required on a case-by-case basis by the District Engineer, the following terms and conditions must be met,as applicable,for a Nationwide Permit authorization to be + valid in Washington State. A. DESCRIPTION OF AUTHORIZED ACTIVITIES .r. 12. Utility Line Activities.Activities required for the construction,maintenance, repair,and removal of utility lines and associated facilities in waters of the United States,provided the activity does not result in the loss of greater than 1/2-acre of waters of the United States for each single and complete project. Utili , lines: This NWP authorizes the construction, maintenance,or repair of utility lines, including outfall and intake structures,and the associated excavation, backfill,or bedding for the utility lines, in all waters of the United States,provided there is no change in pre-construction contours.A "utility line"is defined as any pipe or pipeline for the transportation of any gaseous, liquid, liquescent, or slurry substance,for any purpose,and any cable, line,or wire for the transmission for any purpose of electrical energy,telephone, and telegraph messages, and radio and television communication.The term "utility line"does not include activities that drain a water of the United States, such as drainage tile or french drains,but it does apply to pipes conveying drainage from another area. Material resulting from trench excavation may be temporarily sidecast into waters of the United "■' States for no more than three months,provided the material is not placed in such a manner that it is dispersed by currents or other forces.The district engineer may extend the period of temporary side casting for no more than a total of 180 days,where appropriate. In wetlands,the top 6 to 12 inches of the +lr+ trench should normally be backfilled with topsoil from the trench.The trench cannot be constructed or backfilled in such a manner as to drain waters of the United States(e.g.,backfilling with extensive gravel layers,creating a french drain effect).Any exposed slopes and stream banks must be stabilized immediately upon completion of the utility line crossing of each waterbody. Utility line substations: This NWP authorizes the construction, maintenance,or expansion of substation facilities associated with a power line or utility line in non-tidal waters of the United States, provided the activity, in combination with all other activities included in one single and complete project, does not result in the loss of greater than 1/2-acre of waters of the United States. This NWP does not authorize discharges into non-tidal wetlands adjacent to tidal waters of the United States to construct, maintain,or expand substation facilities. Foundations for overhead utility line towers, poles, and anchors: This NWP authorizes the construction or maintenance of foundations for overhead utility line towers, poles,and anchors in all rtilr waters of the United States,provided the foundations are the minimum size necessary and separate err footings for each tower leg(rather than a larger single pad)are used where feasible. Access roads:This NWP authorizes the construction of access roads for the construction and maintenance of utility lines, including overhead power lines and utility line substations, in non-tidal waters of the United States, provided the activity, in combination with all other activities included in one single and complete project,does not cause the loss of greater than 1/2-acre of non-tidal waters of the United States. This NWP does not authorize discharges into non-tidal wetlands adjacent to tidal waters for access roads.Access roads must be the minimum width necessary(see Note 2,below). Access roads must ` be constructed so that the length of the road minimizes any adverse effects on waters of the United States and must be as near as possible to pre-construction contours and elevations(e.g.,at grade corduroy roads or geotextile/gravel roads).Access roads constructed above pre-construction contours and elevations in waters of the United States must be properly bridged or culverted to maintain surface flows. This NWP may authorize utility lines in or affecting navigable waters of the United States even if there is no associated discharge of dredged or fill material (See 33 CFR Part 322).Overhead utility lines ► constructed over section 10 waters and utility lines that are routed in or under section 10 waters without a discharge of dredged or fill material require a section 10 permit. This NWP also authorizes temporary structures,fills, and work necessary to conduct the utility line activity.Appropriate measures must be taken to maintain normal downstream flows and minimize flooding to the maximum extent practicable,when temporary structures,work,and discharges, including cofferdams,are necessary for construction activities, access fills, or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a manner,that will not be eroded by expected high flows.Temporary fills must be removed in their entirety and the affected areas returned to pre- construction elevations. The areas affected by temporary fills must be revegetated,as appropriate. Notification: The permittee must submit a pre-construction notification to the district engineer prior to commencing the activity if any of the following criteria are met: (1)the activity involves mechanized land clearing in a forested wetland for the utility line right-of-way; (2)a section 10 permit is required; (3)the utility line in waters of the United States,excluding overhead lines, exceeds 500 feet;(4) fo the utility line is placed within a jurisdictional area(i.e.,water of the United States), and it runs parallel to or along a stream bed that is within that jurisdictional area; (5)discharges that result in the loss of greater than 1/10-acre of waters of the United States;(6)permanent access roads are constructed above grade in waters of the United States for a distance of more than 500 feet; or(7)permanent access roads are constructed in waters of the United States with impervious materials. (See general condition 31.) (Sections 10 and 404) rrti Note l: Where the proposed utility line is constructed or installed in navigable waters of the United States(i.e., section 10 waters)within the coastal United States,the Great Lakes, and United States territories,copies of the pre-construction notification and NWP verification will be sent by the Corps to the National Oceanic and Atmospheric Administration(NOAA),National Ocean Service(NOS),for charting the utility line to protect navigation. Note 2:Access roads used for both construction and maintenance may be authorized, provided they meet the terms and conditions of this NWP.Access roads used solely for construction of the utility line must be removed upon completion of the work, in accordance with the requirements for temporary fills. Note 3: Pipes or pipelines used to transport gaseous, liquid, liquescent,or slurry substances over navigable waters of the United States are considered to be bridges, not utility lines,and may require a permit from the U.S.Coast Guard pursuant to Section 9 of the Rivers and Harbors Act of 1899.However, any discharges of dredged or fill material into waters of the United States associated with such pipelines will require a section 404 permit(see NWP 15). Note 4:For overhead utility lines authorized by this NWP, a copy of the PCN and NWP verification will be provided to the Department of Defense Siting Clearinghouse,which will evaluate sri potential effects on military activities. 2 irr B. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPs Note: To qualify for NWP authorization,the prospective permittee must comply with the following general conditions,as applicable, in addition to any regional or case-specific conditions imposed by the division engineer or district engineer.Prospective permittees should contact the appropriate Corps district office to determine if regional conditions have been imposed on an NWP. Prospective permittees should also contact the appropriate Corps district office to determine the status of Clean Water Act Section 401 water quality certification and/or Coastal Zone Management Act consistency for an NWP. Every person who may wish to obtain permit authorization under one or more NWPs, or who is currently relying on an existing or prior permit authorization under one or more NWPs, has been and is on notice that all of the provisions of 33 CFR§ 330.1 through 330.6 apply to every NWP authorization.Note especially 33 CFR §330.5 relating to the modification, suspension,or revocation of any NWP authorization. +rr 1.Navigation.(a)No activity may cause more than a minimal adverse effect on navigation. (b)Any safety lights and signals prescribed by the U.S.Coast Guard,through regulations or otherwise,must be installed and maintained at the permittee's expense on authorized facilities in navigable waters of the United States. (c)The permittee understands and agrees that, if future operations by the United States require the removal, relocation,or other alteration,of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters,the permittee will be required, upon due notice from the Corps of Engineers,to remove, relocate,or alter the structural work or obstructions caused thereby,without expense to the United States.No claim shall be made against the �r United States on account of any such removal or alteration. 2. Aquatic Life Movements.No activity may substantially disrupt the necessary life cycle movements of ow those species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. All permanent and temporary crossings of waterbodies shall be suitably culverted, bridged,or otherwise designed and constructed to w maintain low flows to sustain the movement of those aquatic species. 3. Spawning A` reas.Activities in spawning areas during spawning seasons must be avoided to the „„� maximum extent practicable.Activities that result in the physical destruction(e.g.,through excavation, fill,or downstream smothering by substantial turbidity)of an important spawning area are not authorized. 4. Mi rg atory Bird Breeding Areas. Activities in waters of the United States that serve as breeding areas for migratory birds must be avoided to the maximum extent practicable. 5. Shellfish Beds. No activity may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by NWPs 4 and 48,or is a shellfish seeding or habitat restoration activity authorized by NWP 27. 6. Suitable Material.No activity may use unsuitable material (e.g.,trash, debris,car bodies, asphalt, etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts(see Section 307 of the Clean Water Act). w. 7. Water Supply Intakes.No activity may occur in the proximity of a public water supply intake, except where the activity is for the repair or improvement of public water supply intake structures or adjacent it bank stabilization. 1W ow 8. Adverse Effects From Impoundments.If the activity creates an impoundment of water,adverse effects ir�r to the aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the maximum extent practicable. 9.Management of Water Flows. To the maximum extent practicable,the pre-construction course, condition,capacity,and location of open waters must be maintained for each activity, including stream channelization and storm water management activities,except as provided below.The activity must be constructed to withstand expected high flows.The activity must not restrict or impede the passage of normal or high flows, unless the primary purpose of the activity is to impound water or manage high flows.The activity may alter the pre-construction course,condition,capacity,and location of open waters if it benefits the aquatic environment(e.g., stream restoration or relocation activities). 10. Fills Within 100-Year Floodplains.The activity must comply with applicable FEMA-approved state or local floodplain management requirements. 4 11.Equipment.Heavy equipment working in wetlands or mudflats must be placed on mats, or other measures must be taken to minimize soil disturbance. 12. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction,and all exposed soil and other fills,as well as any work below the ordinary high water mark or high tide line, must be permanently stabilized at the earliest practicable date.Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. wr► 13. Removal of Temporary Fills.Temporary fills must be removed in their entirety and the affected areas returned to pre-construction elevations.The affected areas must be revegetated,as appropriate. 14. Proper Maintenance.Any authorized structure or fill shall be properly maintained, including maintenance to ensure public safety and compliance with applicable NWP general conditions,as well as any activity-specific conditions added by the district engineer to an NWP authorization. 15. Single and Complete Project. The activity must be a single and complete project. The same NWP cannot be used more than once for the same single and complete project. +err 16. Wild and Scenic Rivers.No activity may occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a"study river"for possible inclusion in the system while the river is in an official study status, unless the appropriate Federal agency with direct management responsibility for such river, has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency responsible for the designated Wild and Scenic River or study river(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management, U.S. Fish and Wildlife Service). 17.Tribal Rights.No activity or its operation may impair reserved tribal rights, including,but not Iimited to, reserved water rights and treaty fishing and hunting rights. 18. Endangered Species. (a)No activity is authorized under any NWP which is likely to directly or indirectly jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation,as identified under the Federal Endangered Species Act(ESA),or which will ro directly or indirectly destroy or adversely modify the critical habitat of such species.No activity is 4 wr r authorized under any NWP which"may affect"a listed species or critical habitat, unless Section 7 consultation addressing the effects of the proposed activity has been completed. (b)Federal agencies should follow their own procedures for complying with the requirements of the ESA.Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements.The district engineer will review the documentation and determine whether it is sufficient to address ESA compliance for the NWP activity,or whether additional ESA consultation is necessary. (c)Non-federal permittees must submit a pre-construction notification to the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or if the project is located in designated critical habitat,and shall not begin work on the activity until notified by the district engineer that the requirements of the ESA have been satisfied and that the activity is authorized.For activities that might affect Federally-listed endangered or threatened species or designated critical habitat,the pre-construction notification must include the name(s)of the endangered or threatened +r species that might be affected by the proposed work or that utilize the designated critical habitat that might be affected by the proposed work.The district engineer will determine whether the proposed activity"may affect"or will have"no effect"to listed species and designated critical habitat and will +rr notify the non-Federal applicant of the Corps' determination within 45 days of receipt of a complete pre- construction notification. In cases where the non-Federal applicant has identified listed species or critical habitat that might be affected or is in the vicinity of the project, and has so notified the Corps,the applicant shall not begin work until the Corps has provided notification the proposed activities will have "no effect"on listed species or critical habitat,or until Section 7 consultation has been completed. If the non-Federal applicant has not heard back from the Corps within 45 days,the applicant must still wait for SW notification from the Corps. (d)As a result of formal or informal consultation with the FWS or NMFS the district engineer may add species-specific regional endangered species conditions to the NWPs. (e)Authorization of an activity by a NWP does not authorize the"take"of a threatened or endangered " �'�" species as defined under the ESA. In the absence of separate authorization(e.g., an ESA Section 10 Permit, a Biological Opinion with"incidental take"provisions, etc.)from the U.S. FWS or the NMFS, The Endangered Species Act prohibits any person subject to the jurisdiction of the United States to take a ow listed species, where "take" means to harass, harm,pursue, hunt, shoot,wound, kill,trap,capture,or collect,or to attempt to engage in any such conduct.The word"harm" in the definition of"take"means an act which actually kills or injures wildlife. Such an act may include significant habitat modification or aw degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering. (f)Information on the location of threatened and endangered species and their critical habitat can be No obtained directly from the offices of the U.S. FWS and NMFS or their world wide web pages at http://www.fws.gov/or http://%v%viv.Avs.gov/ipac and littp://„i�vw.noaa.gov/fisheries.html respectively. aw 19. Mharatory Birds and Bald and Golden Eagles.The penniee is responsible for obtaining any"take” pen-nits required under the U.S. Fish and Wildlife Service's regulations governing compliance with the Migratory Bird Treaty Act or the Bald and Golden Eagle Protection Act.The permittee should contact the appropriate local office of the U.S. Fish and Wildlife Service to determine if such"take"permits are �" required for a particular activity. 20. Historic Properties. (a)In cases where the district engineer determines that the activity may affect do properties listed, or eligible for listing, in the National Register of Historic Places,the activity is not authorized,until the requirements of Section 106 of the National Historic Preservation Act(NHPA)have been satisfied. w (b)Federal permittees should follow their own procedures for complying with the requirements of Section 106 of the National Historic Preservation Act.Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. The VW 5 aw 1 district engineer will review the documentation and determine whether it is sufficient to address section sir 106 compliance for the NWP activity, or whether additional section 106 consultation is necessary. (c)Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized activity may have the potential to cause effects to any historic properties listed on,determined to be eligible for listing on,or potentially eligible for listing on the National Register of Historic Places, including previously unidentified properties. For such activities,the pre-construction notification must state which historic properties may be affected by the proposed work or include a vicinity map indicating am the location of the historic properties or the potential for the presence of historic properties.Assistance regarding information on the location of or potential for the presence of historic resources can be sought from the State Historic Preservation Officer or Tribal Historic Preservation Officer,as appropriate,and the National Register of Historic Places(see 33 CFR 330.4(g)). When reviewing pre-construction '� notifications,district engineers will comply with the current procedures for addressing the requirements of Section 106 of the National Historic Preservation Act.The district engineer shall make a reasonable and good faith effort to carry out appropriate identification efforts,which may include background research,consultation,oral history interviews,sample field investigation,and field survey. Based on the information submitted and these efforts,the district engineer shall determine whether the proposed activity has the potential to cause an effect on the historic properties. Where the non-Federal applicant has identified historic properties on which the activity may have the potential to cause effects and so notified the Corps,the non-Federal applicant shall not begin the activity until notified by the district engineer either that the activity has no potential to cause effects or that consultation under Section 106 of the as NHPA has been completed. (d) The district engineer will notify the prospective permittee within 45 days of receipt of a complete pre-construction notification whether NHPA Section 106 consultation is required. Section 106 consultation is not required when the Corps determines that the activity does not have the potential to cause effects on historic properties(see 36 CFR§800.3(a)). If NHPA section 106 consultation is required and will occur,the district engineer will notify the non-Federal applicant that he or she cannot begin work until Section 106 consultation is completed. If the non-Federal applicant has not heard back from the Corps within 45 days,the applicant must still wait for notification from the Corps. (e) Prospective permittees should be aware that section 110k of the NHPA(16 U.S.C.470h-2(k)) prevents the Corps from granting a permit or other assistance to an applicant who,with intent to avoid the requirements of Section 106 of the NHPA,has intentionally significantly adversely affected a historic property to which the pen-nit would relate,or having legal power to prevent it,allowed such significant adverse effect to occur,unless the Corps, after consultation with the Advisory Council on Historic Preservation(ACHP),determines that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify granting the assistance,the Corps is required to notify the ACHP and provide documentation specifying the circumstances,the degree of damage to the integrity of any historic properties affected, and proposed mitigation. This documentation must include any views obtained from the applicant, SHPO/THPO, appropriate Indian tribes if the ,= undertaking occurs on or affects historic properties on tribal lands or affects properties of interest to those tribes,and other parties known to have a legitimate interest in the impacts to the permitted activity on as historic properties. 21. Discovery of Previously Unknown Remains and Artifacts. If you discover any previously unknown historic, cultural or archeological remains and artifacts while accomplishing the activity authorized by this permit,you must immediately notify the district engineer of what you have found,and to the maximum extent practicable, avoid construction activities that may affect the remains and artifacts until the required ► coordination has been completed.The district engineer will initiate the Federal,Tribal and state coordination required to determine if the items or remains warrant a recovery effort or if the site is eligible for listing in the National Register of Historic Places. rr�1 6 rr +■. 22.Designated Critical Resource Waters.Critical resource waters include,NOAA-managed marine sanctuaries and marine monuments,and National Estuarine Research Reserves.The district engineer may designate,after notice and opportunity for public comment,additional waters officially designated by a state as having particular environmental or ecological significance,such as outstanding national resource waters or state natural heritage sites.The district engineer may also designate additional critical resource waters after notice and opportunity for public comment. (a)Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31, 35, 39, 40,42,43,44,49, 50, 51,and 52 for any activity within, or directly affecting,critical resource waters, including wetlands adjacent to such waters. (b)For NWPs 3, 8, 10, 13, 15, 18, 19,22, 23,25, 27,28,30, 33, 34, 36, 37, and 38,notification is required in accordance with general condition 31, for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters.The district engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 23.Mitigation. The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that adverse effects on the aquatic environment are minimal: (a)Tile activity must be designed and constructed to avoid and minimize adverse effects, both temporary and permanent,to waters of the United States to the maximum extent practicable at the project rr site(i.e., on site). (b)Mitigation in all its forms(avoiding, minimizing, rectifying, reducing, or compensating for resource losses)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. aw (c)Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that exceed 1/10-acre and require pre-construction notification, unless the district engineer determines in writing that either some other form of mitigation would be more environmentally appropriate or the adverse effects of the proposed activity are minimal, and provides a project-specific waiver of this requirement. For wetland losses of I/10-acre or less that require pre-construction notification,the district engineer may determine on a case-by-case basis that compensatory mitigation is required to ensure that �s the activity results in minimal adverse effects on the aquatic environment. Compensatory mitigation projects provided to offset losses of aquatic resources must comply with the applicable provisions of 33 CFR part 332. (1)The prospective permittee is responsible for proposing an appropriate compensatory r mitigation option if compensatory mitigation is necessary to ensure that the activity results in minimal adverse effects on the aquatic environment.(2) Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced,wetland restoration should be the first compensatory mitigation option considered.(3)If permittee-responsible mitigation is the proposed option,the prospective permittee is.responsible for submitting a mitigation plan.A conceptual or detailed mitigation plan may be used by the district engineer to make the decision on the NWP verification request, but a final mitigation plan that addresses the applicable requirements of 33 CFR 332.4(c)(2)-(14) must be approved by the district engineer before the permittee begins work in waters of the United States, unless the district engineer determines that prior approval of the final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation(see 33 CFR 332.3(k)(3)). (4)If mitigation bank or in-lieu fee program credits are the proposed option,the mitigation plan only needs to address the baseline conditions at the impact site and the number of credits to be provided. (5)Compensatory mitigation requirements(e.g.,resource type and amount to be provided as so compensatory mitigation,site protection,ecological performance standards, monitoring requirements) may be addressed through conditions added to the NWP authorization, instead of components of a compensatory mitigation plan. .r (d)For losses of streams or other open waters that require pre-construction notification,the district engineer may require compensatory mitigation, such as stream rehabilitation,enhancement, or preservation,to ensure that the activity results in minimal adverse effects on the aquatic environment. 7 (e)Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage go limits of the NWPs.For example,if an NWP has an acreage limit of 1/2-acre, it cannot be used to authorize any project resulting in the loss of greater than 1/2-acre of waters of the United States,even if compensatory mitigation is provided that replaces or restores some of the lost waters. However, compensatory mitigation can and should be used,as necessary,to ensure that a project already meeting the established acreage limits also satisfies the minimal impact requirement associated with the NWPs. (f)Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the restoration or establishment,maintenance,and legal protection(e.g., conservation easements)of riparian areas next to open waters.In some cases,riparian areas may be the only compensatory mitigation required. Riparian areas should consist of native species.The width of the required riparian area will address documented water quality or aquatic habitat loss concerns.Normally, the riparian area will be 25 to 50 feet wide on each side of the stream, but the district engineer may require slightly wider riparian areas to address documented water quality or habitat loss concerns.If it is not possible to establish a riparian area on both sides of a stream,or if the waterbody is a lake or coastal waters,then restoring or establishing a riparian area along a single bank or shoreline may be sufficient. Where both wetlands and open waters exist on the project site,the district engineer will determine the appropriate compensatory mitigation (e.g., riparian areas and/or wetlands compensation)based on what is rrit best for the aquatic environment on a watershed basis. In cases where riparian areas are determined to be the most appropriate form of compensatory mitigation,the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses. nr (g)Permittees may propose the use of mitigation banks, in-lieu fee programs,or separate permittee- responsible mitigation. For activities resulting in the loss of marine or estuarine resources,permittee- responsible compensatory mitigation may be environmentally preferable if there are no mitigation banks or in-lieu fee programs in the area that have marine or estuarine credits available for sale or transfer to the permittee. For permittee-responsible mitigation,the special conditions of the NWP verification must clearly indicate the party or parties responsible for the implementation and performance of the so compensatory mitigation project, and, if required, its long-term management. (h)Where certain functions and services of waters of the United States are permanently adversely affected, such as the conversion of a forested or scrub-shrub wetland to a herbaceous wetland in a permanently maintained utility line right-of-way, mitigation may be required to reduce the adverse effects of the project to the minimal level. 24. Safety of Impoundment Structures.To ensure that all impoundment structures are safely designed, the district engineer may require non-Federal applicants to demonstrate that the structures comply with established state dam safety criteria or have been designed by qualified persons.The district engineer may also require documentation that the design has been independently reviewed by similarly qualified persons, and appropriate modifications made to ensure safety. 25. Water Ouality. Where States and authorized Tribes,or EPA where applicable, have not previously certified compliance of an NWP with CWA Section 401, individual 401 Water Quality Certification must be obtained or waived(see 33 CFR 330.4(c)). The district engineer or State or Tribe may require additional water quality management measures to ensure that the authorized activity does not result in more than minimal degradation of water quality. 26. Coastal Zone Mana eg ment. In coastal states where an NWP has not previously received a state coastal zone management consistency concurrence, an individual state coastal zone management consistency concurrence must be obtained,or a presumption of concurrence must occur(see 33 CFR 330.4(d)).The district engineer or a State may require additional measures to ensure that the authorized activity is consistent with state coastal zone management requirements. 8 +rr �r 27. Regional and Case-Bv-Case Conditions.The activity must comply with any regional conditions that may have been added by the Division Engineer(see 33 CFR 330.4(e))and with any case specific conditions added by the Corps or by the state, Indian Tribe,or U.S.EPA in its section 401 Water Quality Certification, or by the state in its Coastal Zone Management Act consistency determination. 28.Use of Multiple Nationwide Permits.The use of more than one NWP for a single and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit. For example, if a road crossing over tidal waters is constructed under NWP 14,with associated bank stabilization authorized by NWP 13,the maximum acreage loss of waters of the United States for the total project cannot exceed 1/3-acre. 29. Transfer of Nationwide Permit Verifications. If the permittee sells the property associated with a ft nationwide permit verification,the permittee may transfer the nationwide permit verification to the new owner by submitting a letter to the appropriate Corps district office to validate the transfer. A copy of the nationwide permit verification must be attached to the letter,and the letter must contain the following err statement and signature: "When the structures or work authorized by this nationwide permit are still in existence at the time the property is transferred,the terms and conditions of this nationwide permit, including any special conditions,will continue to be binding on the new owner(s)of the property.To validate the transfer of this nationwide permit and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign and date below." (Transferee) (Date) wr 30. Compliance Certification.Each permittee who receives an NWP verification letter from the Corps must provide a signed certification documenting completion of the authorized activity and any required compensatory mitigation. The success of any required permittee-responsible mitigation, including the achievement of ecological performance standards, will be addressed separately by the district engineer. The Corps will provide the permittee the certification document with the NWP verification letter. The err certification document will include: (a)A statement that the authorized work was done in accordance with the NWP authorization, including any general, regional, or activity-specific conditions;(b)A statement that the implementation of any required compensatory mitigation was completed in accordance with the permit conditions. If credits from a mitigation bank or in-lieu fee program are used to satisfy the compensatory mitigation requirements,the certification must include the documentation required by 33 CFR 332.3(1)(3)to confirm that the permittee secured the appropriate number and resource type of r credits;and(c)The signature of the permittee certifying the completion of the work and mitigation. 31.Pre-Construction Notification. (a)Timing. Where required by the terms of the NWP,the prospective permittee must notify the district engineer by submitting a pre-construction notification(PCN)as early as "" possible.The district engineer must determine if the PCN is complete within 30 calendar days of the date of receipt and, if the PCN is determined to be incomplete, notify the prospective permittee within that 30 day period to request the additional information necessary to make the PCN complete.The request must 40 specify the information needed to make the PCN complete.As a general rule,district engineers will request additional information necessary to make the PCN complete only once. However, if the prospective permittee does not provide all of the requested information,then the district engineer will notify the prospective permittee that the PCN is still incomplete and the PCN review process will not commence until all of the requested information has been received by the district engineer.The prospective permittee shall not begin the activity until either: (1) He or she is notified in writing by the �r 9 r district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division engineer; or(2)45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice from the district or division engineer. However, if the permittee was required to notify the Corps pursuant to general condition 18 that listed species or critical habitat might be affected or in the vicinity of the project,or to notify the Corps pursuant to general condition 20 that the activity may have the potential to cause effects to historic properties,the permittee cannot begin the activity until receiving written notification from the Corps that there is"no effect"on listed species or"no potential to cause effects"on historic properties, or that any consultation required under Section 7 of the Endangered Species Act(see 33 CFR 330.4(f)) and/or Section 106 of the National Historic Preservation(see 33 CFR 330.4(g))has been completed.Also,work cannot begin under NWPs 21,49,or 50 until the pernittee has received written approval from the Corps. If the proposed activity requires a written waiver to exceed specified limits of an NWP,the permittee may not begin the activity until the district engineer issues the waiver.If the district or division engineer notifies the permittee in writing that an individual permit is required within 45 calendar days of receipt of grit a complete PCN,the permittee cannot begin the activity until an individual permit has been obtained. Subsequently,the permittee's right to proceed under the NWP may be modified, suspended,or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2). (b)Contents of Pre-Construction Notification: The PCN must be in writing and include the following information: (1)Name, address and telephone numbers of the prospective permittee; (2)Location of the proposed project;(3)A description of the proposed project;the project's purpose; direct and indirect adverse environmental effects the project would cause, including the anticipated amount of loss of water of the United States expected to result from the NWP activity, in acres, linear feet, or other appropriate unit of measure; any other NWP(s),regional general permit(s),or individual permit(s)used or intended to be used to authorize any part of the proposed project or any related activity.The description should be sufficiently detailed to allow the district engineer to detennine that the adverse effects of the project will be minimal and to determine the need for compensatory mitigation. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP.(Sketches usually clarify the project and when provided results in a quicker decision. Sketches should contain sufficient detail to provide an illustrative description of the proposed activity(e.g.,a conceptual plan),but do not need to be detailed engineering plans); (4)The PCN must include a delineation of wetlands,other special aquatic sites, and other waters,such as lakes and ponds,and perennial, intermittent,and ephemeral streams, on the project site. Wetland delineations must be prepared in accordance with the current method required by the Corps.The permittee may ask the Corps to delineate the special aquatic sites and other waters on the wir project site,but there may be a delay if the Corps does the delineation,especially if the project site is large or contains many waters of the United States. Furthermore,the 45 day period will not start until the delineation has been submitted to or completed by the Corps, as appropriate;(5) If the proposed activity will result in the loss of greater than 1/10-acre of wetlands and a PCN is required,the prospective permittee must submit a statement describing how the mitigation requirement will be satisfied,or explaining why the adverse effects are minimal and why compensatory mitigation should not be required. As an alternative,the prospective permittee may submit a conceptual or detailed mitigation plan. (6)If any listed species or designated critical habitat might be affected or is in the vicinity of the project, or if the project is located in designated critical habitat,for non-Federal applicants the PCN must include the name(s)of those endangered or threatened species that might be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work.Federal applicants must provide documentation demonstrating compliance with the Endangered Species Act; and(7)For an activity that may affect a historic property listed on,determined to be eligible for listing on, or potentially eligible for sit listing on,the National Register of Historic Places,for non-Federal applicants the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. Federal applicants must provide documentation demonstrating compliance with Section 106 of the National Historic Preservation Act. w 10 (c)Form of Pre-Construction Notification: The standard individual permit application form(Form ENG 4345)may be used, but the completed application form must clearly indicate that it is a PCN and must include all of the information required in paragraphs (b)(1)through(7)of this general condition.A letter containing the required information may also be used. (d)Agency Coordination: (1)The district engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the project's adverse environmental effects to a minimal level. (2) For all NWP activities that require pre-construction notification and result in the loss of greater than 112- acre of waters of the United States,for NWP 21,29,39,40,42,43,44, 50, 51, and 52 activities that require pre-construction notification and will result in the loss of greater than 300 linear feet of " intermittent and ephemeral stream bed, and for all NWP 48 activities that require pre-construction notification,the district engineer will immediately provide(e.g.,via e-mail, facsimile transmission, overnight mail,or other expeditious manner)a copy of the complete PCN to the appropriate Federal or state offices(U.S. FWS, state natural resource or water quality agency, EPA, State Historic Preservation Officer(SHPO)or Tribal Historic Preservation Office(THPO), and, if appropriate,the NMFS). With the exception of NWP 37,these agencies will have 10 calendar days from the date the material is transmitted .• to telephone or fax the district engineer notice that they intend to provide substantive, site-specific comments.The comments must explain why the agency believes the adverse effects will be more than minimal. If so contacted by an agency,the district engineer will wait an additional 15 calendar days before making a decision on the pre-construction notification.The district engineer will fully consider agency comments received within the specified time frame concerning the proposed activity's compliance with the terms and conditions of the NWPs, including the need for mitigation to ensure the net adverse environmental effects to the aquatic environment of the proposed activity are minimal.The district engineer will provide no response to the resource agency, except as provided below. The district engineer will indicate in the administrative record associated with each pre-construction notification that the resource agencies' concerns were considered. For NWP 37,the emergency watershed protection and rehabilitation activity may proceed immediately in cases where there is an unacceptable hazard to life or a significant loss of property or economic hardship will occur.The district engineer will consider any comments received to decide whether the NWP 37 authorization should be modified, suspended, or revoked in accordance with the procedures at 33 CFR 330.5. (3) In cases of where the prospective permittee is not a Federal agency,the district engineer will provide a response to NMFS within 30 calendar days of receipt of any Essential Fish Habitat conservation recommendations, as required by .iw Section 305(b)(4)(B)of the Magnuson-Stevens Fishery Conservation and Management Act. (4) Applicants are encouraged to provide the Corps with either electronic files or multiple copies of pre- construction notifications to expedite agency coordination. r District Engineer's Decision 1. In reviewing the PCN for the proposed activity,the district engineer will determine whether the WA activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or maybe contrary to the public interest. For a linear project,this determination will include an evaluation of the individual crossings to determine whether they individually satisfy the terms and conditions of the NWP(s), as well as the cumulative effects caused by all of the crossings authorized by NWP. If an applicant requests a waiver of the 300 linear foot limit on impacts to intermittent or ephemeral streams or of an otherwise applicable limit,as provided for in NWPs 13,21,29, 36, 39,40,42,43,44, 50,51 or 52,the district engineer will only grant the waiver upon a written determination that the NWP activity will result in minimal adverse effects. When making minimal effects determinations the district engineer will consider the direct and indirect effects caused by the NWP activity. The district engineer will also consider site specific factors,such as the environmental setting in `. the vicinity of the NWP activity,the type of resource that will be affected by the NWP activity,the functions provided by the aquatic resources that will be affected by the NWP activity,the degree or magnitude to which the aquatic resources perform those functions,the extent that aquatic resource it aw functions will be lost as a result of the NWP activity(e.g.,partial or complete loss),the duration of the wrt adverse effects(temporary or permanent),the importance of the aquatic resource functions to the region (e.g.,watershed or ecoregion),and mitigation required by the district engineer. If an appropriate functional assessment method is available and practicable to use,that assessment method may be used by 4* the district engineer to assist in the minimal adverse effects determination.The district engineer may add case-specific special conditions to the NWP authorization to address site-specific environmental concerns. 2. If the proposed activity requires a PCN and will result in a loss of greater than 1/1 Q-acre of wetlands,the prospective permittee should submit a mitigation proposal with the PCN.Applicants may also propose compensatory mitigation for projects with smaller impacts.The district engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed activity are minimal. The compensatory mitigation proposal may be either conceptual or detailed. If the district engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the aquatic environment are minimal,after considering mitigation,the district engineer will notify the permittee and include any activity-specific conditions in the NWP verification the district engineer deems necessary. Conditions for compensatory mitigation requirements must comply with the appropriate provisions at 33 CFR 332.3(k).The district engineer must approve the final mitigation plan before the permittee commences work in waters of the United States, unless the district engineer determines that prior approval of the final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN,the district engineer will expeditiously review the proposed compensatory mitigation plan.The district engineer must review the proposed compensatory mitigation plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal) are determined by the district engineer to be minimal,the district engineer will provide a timely written 10 response to the applicant.The response will state that the project can proceed under the terms and conditions of the NWP, including any activity-specific conditions added to the NWP authorization by the district engineer. 3.If the district engineer determines that the adverse effects of the proposed work are more than minimal,then the district engineer will notify the applicant either: (a)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; (b)that the project is authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level;or(c)that the project is authorized under the NWP with specific modifications or conditions. Where the district engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period, with activity-specific conditions that state the mitigation requirements.The authorization will include the necessary conceptual or detailed mitigation or a requirement that the applicant submit a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is required, no work in waters of the United States may occur until the district engineer has approved a specific mitigation plan or has determined that prior approval of a final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation.

F. STATE 401 CERTIFICATION SPECIFIC CONDITIONS FOR THIS NWP: Certified subject to conditions. Permittee must meet Ecology 401 General Conditions. Individual 401 review required for projects or activities authorized under this NWP if- 1. The entire utility line project or activity impacts more than ''/z acre of wetlands. 18 aw Note:Projects or activities that need a FERC license will be required to obtain an Individual 401 Certification as part of the FERC license process. G. EPA 401 CERTIFICATION GENERAL CONDITIONS: A.Any activities in the following types of wetlands and waters of the United States will need to apply for an individual 401 certification: Mature forested wetlands,bogs, bog-like wetlands, wetlands in dunal systems along the Washington coast,coastal lagoons, vernal pools,aspen-dominated wetlands,alkali wetlands,camas prairie wetlands,estuarine wetlands, including salt marshes,and marine waters with eelgrass or kelp beds. wr B.A 401 certification determination is based on the project or activity meeting established turbidity levels.The EPA will be using as guidance the state of Washington's water quality standards [WAC 173- 201a] and sediment quality standards [WAC 173-204].Projects or activities that are expected to exceed these levels or that do exceed these levels will require an individual 401 certification. +r The water quality standards allow for short-term turbidity exceedances after all necessary Best Management Practices have been implemented(e.g.,properly placed and maintained filter fences, hay bales and/or other erosion control devices,adequate detention of runoff to prevent turbid water from flowing off-site, providing a vegetated buffer between the activity and open water,etc.), and only up to the following limits: Wetted Stream Width at Discharge Point Approximate Downstream Point for Determining Compliance Up to 30 feet 50 feet >30 to 100 feet 100 feet >100 feet to 200 feet 200 feet >200 feet 300 feet LAKE,POND, RESERVOIR Lesser of 100 feet or maximum surface dimension s C.401 certification of projects and activities under NWPs will use Washington State Department of Ecology's most recent stormwater manual or an EPA approved equivalent manual as guidance in meeting water quality standards. D. For projects and activities requiring coverage under an NPDES permit,certification is based on compliance with the requirements of that permit. Projects and activities not in compliance with NPDES requirements will require individual 401 certification. E.Individual 401 certification is required for projects or activities authorized under NWPs if the •• project will discharge to a waterbody on the list of impaired waterbodies(the 303(d)List)and the discharge may result in further exceedance of a specific parameter the waterbody is listed for.The EPA shall make this determination on a case-by-case basis.

Applicant. City of Renton. 3 2. Hearing. The Examiner held a hearing on the subject application on September 18, 2013 at 4 1:30 pm in the City of Renton Council Chambers. 5 Substantive: 6 3. Project Description. The City of Renton is requesting a shoreline substantial development 7 permit and shoreline conditional use permit in order to install 3,330 linear feet of a 60-inch diameter storm drain parallel to an existing storm system, from its current outfall at Naches Ave SW to 8 approximately Lind Ave SW. Most of the project would occur within the rights-of-way of SW 7th St 9 and Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW. The project includes the 10 construction of an additional stormwater outfall in a Class 2 stream (Stream A) that runs east to west on the northern boundary of the City-owned property (Parcel #9188000154). The project would also 11 retrofit the drainage condition installing Filterra Systems along SW 7th St; from Naches Ave SW to 12 Lind Ave SW. The project site is primarily located within the public right-of-way. The portion of the project area west of Powell Ave SW is zoned Commercial Office (CO). The eastern portion of the 13 project area is zoned Medium Industrial (IM). The area of impact would be approximately 270,000 square feet and is largely undeveloped with the exception of utilities. Construction is expected to 14 begin in Spring of 2014 and be complete by June of 2015. 15 4. Surrounding Area. The project area is located in a wildlife conservation area associated 16 with the Black River Riparian Forest. Adjoining parcels are characterized by warehouse and office use. 17 18 5. Adverse Impacts. There are no significant adverse impacts associated with the project. As an underground utility project, the proposal will not create any post-construction noise, traffic, parking, 19 navigation or visual impacts. As to compatibility, the project is located within the public right-of- way. Construction traffic is addressed by MDNS mitigation. Surrounding land uses include both 20 commercial and industrial properties. The proposed storm drain, to be installed adjacent to the 21 existing storm system would not alter the existing land uses in the area and has already proven to be compatible. Water quality will not be adversely affected by the proposal. Overall the proposal will 22 improve water quality in the Black River basin and the project will incorporate Filterra systems to provide for enhanced basic water treatment. The staff report notes that it is unlikely that any cultural 23 or archaeological resources are present at the site and the MDNS requires actions to be taken should any resources be discovered during construction. The primary impacts of concern are impacts to 24 wetlands and a stream, more specifically addressed as follows: 25 A. Wetlands. There are two wetlands within the project area. A Wetland 26 Assessment Report and Buffer Mitigation Plan was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 4). Hererra biologists delineated SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 2 am +w 1 the two wetlands and identified them as Wetlands A and B. Wetland A, a 2 Catergory 1 wetland, is a large palustrine forested depressional wetland complex that is contiguous with the Black River Riparian Forest which is subject to the 3 Renton Shoreline Master Program (RMC4-3-090). Wetland B, a Category 3 4 wetland, is a palustrine forested wetland that occupies the southern portion of the City-owned parcel and is also subject to the Renton Shoreline Master Program 5 (Exhibit 10). No work would occur within the wetlands themselves, but 700 square feet would be temporarily cleared in the buffer to Wetland A. Mitigation 6 requires re-vegetation of the cleared area. The mitigation recommended in the 7 Herrera report was prepared by a qualified professional and was accepted by staff. M The recommended mitigation adequate mitigates wetland impacts and is imposed g through the MDNS. + 9 B. Stream. An unnamed tributary to the Black River (Stream A) is also located within the project area. A Stream Study was submitted by the applicant, prepared 10 by Herrera on May 24, 2013 (Exhibit 6). The stream was classified as a Class 2 11 stream with a 100-foot buffer. The existing 60-inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60-inch 12 storm drain will outfall adjacent to the existing culvert outlet. The stream at this location is currently armored with rock. A temporary stream bypass will be 13 necessary to construct the outlet. Since the buffer of Stream A overlaps with the Aw 14 buffer of Wetland A, buffer impacts and consequent performance standards are included in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 15 4)• 16 The Muckleshoot Tribe submitted written comment expressing concern over an 17 increase in stream velocity that would be caused by the new outfall location into the stream. That increased velocity could adversely affect protected fish. In 18 response to this concern staff added mitigation requiring the addition of large woody debris to the stream. Staff and the Tribe found this additional mitigation to 19 adequately address velocity impacts and the mitigation is imposed through the 20 MDNS. The tribe also suggested the use of alternative vegetation for the required planting plan and the applicant has agreed to consider it. 21 C. No Net Loss of Ecological Function. The proposal will not crate any net loss of 22 ecological shoreline function. The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of 23 vegetation clearing. The Wetland Assessment Report and Buffer Mitigation Plan 24 contains a buffer mitigation and vegetation management plan for the re-vegetation of cleared areas (Exhibit 4). The plan includes approaches for no net loss of 25 ecological functions and for mitigation sequencing. Proposed performance standards are described to compensate for unavoidable temporary impacts to 26 buffers. There are provisions for re-vegetating cleared areas with native plant SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 3 I species and removing invasive plant species. The applicant is proposing to plant 2 Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern. The maintenance and monitoring program is proposed for a 3 minimum of five years to ensure adequate establishment of installed vegetation 4 and adequate cover of native vegetation and trees. A mitigation measure, as part of the SEPA determination, was issued requiring the submittal of a detailed final 5 mitigation plan (Exhibit 13). The final mitigation plan will be required to be reviewed and approved by the Current Planning Project Manager, prior to the 6 approval of construction permits. 7 Conclusions of Law 8 9 1. Authority. RMC 4-8-080(G) classifies shoreline substantial development permits as Type II 10 applications and shoreline conditional use permits as Type III applications. RMC 4-8-080(C)(2) requires consolidated permits to each be processed under "the highest-number procedure". The 11 shoreline variance has the highest numbered review procedure, so both shoreline permits must be 12 processed as Type III applications. As Type III applications, RMC 4-8-080(G) grants the Examiner with the authority to hold a hearing and issue a final decision on them, subject to closed record appeal 13 to the City Council. 14 2. Shoreline Desi agn tions. Natural. 15 3. Review Criteria. RMC 4-3-090(E)(1) requires shoreline conditional use permits for 16 structures for floodway management, including drainage facilities. Conditional use criteria are 17 governed by RMC 4-9-030(D). The criteria for shoreline substantial development permits are set by RMC 4-9-190(B)(7), which requires compliance with all SMP use regulations and substantial 18 compliance with SMP policies. All applicable criteria are quoted below in italics and applied 19 through corresponding conclusions of law. The staff report analysis of compliance with RMC 4- 20 3.090(D) is adopted and incorporated by this reference as if set forth in full. 21 SMP Policies 22 SMP Objective U-F: Provide and maintain surface water management systems to minimize impacts on natural systems and to protect the public, property, surface water bodies, fish habitat, and A 23 groundwater from changes in the quantity and quality of storm water runoff due to land use changes. 24 4. As determined in FOF No. 5, as mitigated the proposal will not adversely affect stream or 25 wetlands and those are the only natural systems potentially affected by the proposal. No impacts to public property are anticipated since the proposal will be primarily located underground. 26 SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 4 r 1 SMP Policy SH-6: Shoreline use and development should be carried out in a manner that prevents 2 or mitigates adverse impacts so that the resulting ecological condition does not become worse than 3 the current condition. This means ensuring no net loss of ecological functions and processes in all development and use. Permitted uses should be designed and conducted to minimize, in so far as 4 practical, any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline 5 ecological functions that should be protected include, but are not limited to,fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall be protected 6 include, but are not limited to, water flow; littoral drift; erosion and accretion; infiltration; ground 7 water recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input; nutrient and pathogen removal; and stream channel 8 formation/maintenance. �. 9 5. As determined in FOF No. 5, the only ecological systems potentially affected by the proposal 10 are wetlands and streams and no adverse impacts are anticipated as to those resources. As further 11 determined in FOF No. 5, the proposal will not result in any net loss of ecological function. 12 RMC 4-3-090(E)(11)(a)(i): Local utility services needed to serve water-dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual 13 compatibility. 14 6. As determined in FOF No. 5, the proposal will not create any adverse ecological or visual 15 impacts. 16 RMC 4-3-090(E)(11)(a)(ii): Major utility systems shall be located outside of shoreline jurisdiction, 17 to the extent feasible, except for elements that are water-dependent and crossings of water bodies 18 and other elements of shorelands by linear facilities. 19 7. The proposal cannot be placed outside the shoreline jurisdiction since it involves the relocation of an existing water dependent storm water system that discharges into a stream. The 20 system also qualifies as linear so its temporary impacts to a wetland buffer are authorized by the 21 criterion above. 22 RMC 4-3-090(E)(11)(a)(vi): Utilities shall be located in existing rights-of-way and corridors, 23 whenever reasonably feasible. ,,, 24 18. Most of the project would occur within the rights-of-way of SW 7th St and Naches Ave with a 25 short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW. 26 w. SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 5 f 1 RMC 4-3-090(E)(11)(b)(i): Installation and operation of pipelines shall protect the natural 2 conditions of adjacent water courses and shorelines. 3 9. As determined in FOF No. 5, the proposal will not adversely affect any natural resources, 4 including adjacent water courses and shorelines. 5 RMC 4-3-090(E)(11)(b)(ii): Water quality is not to be degraded to the detriment of aquatic life 6 nor shall water quality standards be violated. 7 10. As determined in FOF No. 5, the proposal will not create any significant adverse water 8 quality impacts and will in fact be improved by the proposal. 9 RMC 4-3-090(E)(11)(c)(iii): All pipeline utilities shall be underground. When underground 10 projects are completed on the bank of a water body or in the shoreland or a shoreline, the disturbed area shall be restored to the original configuration. Underground utility installations shall be 11 permitted only when the finished installation shall not impair the appearance of such areas. 12 11. The proposed storm drain would be installed underground adjacent to the existing storm 13 system. No work would occur within the wetland/shoreline area. 14 SHORELINE CONDITIONAL USE CRITERIA 15 16 4-3-190(I)t: The use must be compatible with other permitted uses within that area. 17 12. As determined in FOF No. 5, the proposal is compatible with other permitted uses in the 18 area. 19 4-3-190(I): The use will not interfere with the public use of public shorelines. 20 13. The utility lines will be underground and so will not interfere with public use of the 21 shorelines. 22 4-3-190(I): Design of the site will be compatible with the surroundings and the Shoreline Master 23 Program. .h 24 25 26 1 The conditional use criteria were taken from the staff report, as the on-line version of the Renton Municipal Code does not appear to currently include the criteria. to SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 6 1 14. As determined in FOF No. 5, the proposal is compatible with the surroundings. The project 2 will involve a temporary clearing of a wetland buffer, but required mitigation involves re-vegetation. The proposal is compatible with the Shoreline Master Program since it complies with all applicable 3 regulations and policies as addressed in this decision. 4 4-3-190(I): The use shall be in harmony with the general purpose and intent of the Shoreline 5 Master Program. 6 15. The general purpose of the City's Shoreline Master Program is to manage the shoreline for 7 long term benefit preserving ecology and natural character and increasing recreational opportunities and public access. While the proposal would have no impact on the recreational opportunities and 8 public access the proposal would improve water quality in the Black River drainage basin, improve 9 conveyance at the South Renton basin, and reduce flooding at the Hardie Ave underpass. The project would also maintain the natural drainage course. As a result the proposed project would be in 10 harmony with the general purpose and intent of the Shoreline Master Program. 11 4-3-190(I): The use meets the conditional use criteria in WAC 173-27-160: 12 1. Uses which are classified or set forth in the applicable master program as conditional uses may be authorized provided that the applicant demonstrates all of the following: 13 (a) That the proposed use is consistent with the policies of RCW 90.58.020 and the master 14 Program; (b) That the proposed use will not interfere with the normal public use of public shorelines; 15 (c) That the proposed use of the site and design of the project is compatible with other 16 authorized uses within the area and with uses planned for the area under the comprehensive plan and shoreline master program; 17 (d) That the proposed use will cause no significant adverse effects to the shoreline 18 environment in which it is to be located; and (e) That the public interest suffers no substantial detrimental effect. 19 2. In the granting of all conditional use permits, consideration shall be given to the cumulative impact of additional requests for like actions in the area. For example, if 20 conditional use permits were granted for other developments in the area where similar 1W 21 circumstances exist, the total of the conditional uses shall also remain consistent with the policies of RCW 90.58.020 and shall not produce,substantial adverse effects to the shoreline 22 environment. 23 16. As previously concluded, the proposal is consistent with the policies of the Shoreline 24 Management Act, will not interfere with normal public use of the shorelines and is compatible with other authorized shoreline uses. As determined in IFOF No. 5, the proposal will not create any 25 significant adverse impacts while overall improving water quality so the public interest will suffer no 26 substantial detrimental effect. The impacts of the proposal are sufficiently minimal and the overall impacts are positive such that there are no associated adverse cumulative impacts. SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 7 Ab 1 2 DECISION 3 The shoreline substantial development permit and shoreline conditional use permit applications meet all applicable shoreline policies and regulations as outlined in this decision. The permit 4 applications are approved subject to the following conditions: 5 1. The applicant shall comply with the 6 mitigation measures issued as part of the 6 Determination of Non-Significance Mitigated, dated August 19, 2013 (Exhibit 12). 2. The applicant shall consider alternative vegetation for required re-vegetation as requested by 7 the Muckleshoot Tribe. 8 DATED this 1St day October, 2013. 9 ot 10 11 City of Renton Hearing Examiner 12 13 14 Appeal Right and Valuation Notices 15 RMC 4-8-110(E)(9) provides that the final decision of the Hearing Examiner is subject to appeal to the Renton City Council.

The purpose of this network is to provide an accessible common datum for all public and private projects within the city. Thus facilitating city wide infrastructure management and analysis and assuring compatibility between the various utility systems and system projects. This project started in 1992 with the formation of a Horizontal and Vertical Control Network Committee to prepare a plan for the development and maintenance of a Survey Control Network for the City. The committee members were: +�++ Robert Anderson PLS; Bush,Roed&Hitchings,Inc., Carrie Davis; Technical Services Section(Recorder), Abdoul Gafour; Utility Systems Division, Arneta Henninger; Plan Review Section,Development Services Division, Jae Lee; Transportation Systems Division, Robert Mac Onie; Technical Services Section(Chairman), Jon Warren PLS; Dodds Engineers, Inc., Dennis Wegenast; National Geodetic Survey. The committee developed the standards, specifications and phasing for all ensuing work. All survey work meets the requirements specified by the Federal Geodetic Control Committee in Standards and Specifications for Geodetic Control Networks dated September 1984. The project was split into three phases: 1) monument recovery, 2) horizontal „ control and 3)vertical control. The monument recovery project was performed by Dodds Engineers, Inc., under the direction of Jon Warren PLS in 1992 and early 1993. This project identified existing Public Land Survey System corner monuments and other monuments (NGS, C&GS, King County, City of Bellevue, major intersections and those located near current and proposed capital improvement projects) important to the development of a survey control network. In most cases, street centerline monuments were selected for both horizontal and vertical control due to stability and maintenance considerations. The second and third phases ran concurrently during 1993 & 1994. The horizontal control phase was executed by Bush, Roed & Hitchings, under the direction of Robert Anderson PLS, using Global Positioning Systems (GPS) technology per the Federal Geodetic Control Subcommittee Standards for GPS control surveys as defined in Geometric Geodetic Accuracy Standards & Specifications for Using GPS Relative Positioning Techniques dated August 1, 1989. This phase established NAD 1983/1991, Washington State Plane, 2nd Order, 1st Class, northing and easting values for 122 monuments in and a TS_SERVER//SYS2Vv A-PS\$3m\control\scn.doe 1 2 May 2000 go around the City. Four NAD 1983/1991 National Geodetic Survey (NGS) high precision geodetic network (HPGN) monuments (BROWN, PT B 1962, HAFF and MUD MTN) controlled the GPS survey. All coordinates show are "Washington Coordinate System of 1983/1991,North Zone." The vertical control phase was performed by Triad Associates, under the direction of Brad Freeman PLS, using a Wild NA2000 automatic auto reading level and Star*Lev adjustment software. This phase established NAVD 1988, 3rd Order, lst Class, elevations on 190 monuments in and around the City with 70 of these being horizontal control monuments as well. The leveling project was divided into seven primary interdependent loops connected at a minimum of two points with common benchmarks. Additional legs were run across the primary loops tying into two benchmarks at both ends. A total of 15 NGS benchmarks were part of the network, four of which were held in the final adjustment (NGS Archive Numbers SY0232, SY0162, SY0163 and SY0617) and provided substantial agreement(less than or equal to 5mm)with 5 others. The City, in 1995, will have reference points set for all Survey Control Network street centerline monuments not currently referenced. Over the next several years monuments in need of upgrade will be reset as part of an ongoing maintenance program or where capital improvement projects would likely disturb them. As an adjunct to the Survey Control Network the city has developed the enclosed ++� Surveying Standards. Al Hebrank of Hebrank & Associates developed the first draft of these standards which were modified to require the use of the Survey Control Network for all public and private development projects within the city and define the responsibilities of the surveyor in the establishment of new monuments and their associated records. The standards have been reviewed by at least ten licensed surveyors for completeness and suitability. The City of Renton and its urban growth area lie between latitudes 47° 25' North to the south and 47° 32' 30" North to the north. In most cases the combined scale factor (elevation and grid scale) throughout this area can be treated as equal to 1.0000000. Table 1. shows the grid scale factors for each minute of latitude in the Renton area identified above. Please note that the relative accuracy for the grid scale factors is approximately 1 in • 60,000 at 470 25' N to the south and 1 in 111,000 at 470 33' N to the north and thus for most survey work will have no impact on surveys covering less than 1.5 miles. w,r aw TS_SERVER/1SYS2\MAPS\83m\control\scn.doc it 2 May 2000 ■r TABLE 1.

SEA LEVEL REDUCTION TABLE Renton Elevation Sea Level Feet Factor Sea Level 1.0000000 500 0.9999761 1000 0.9999522 The worst case relative accuracy for an elevation of 650 feet with an interpolated scale factor of 0.99996893 is approximately 1 in 32,000. When combined with the worst case ' grid scale factor of 0.99999195 it yields a combined factor of 0.99995998 for a relative accuracy of approximately 1 in 25,000. It should be noted that Washington state uses the US survey foot and the conversion between feet and meters is 3 93 7/1200 or 3.28083333 feet per meter. An analysis of the differences between NGVD 1929 and NAVD 1988 elevations in and around Renton yields a conversion factor of+1.092 meters going from NGVD 1929 to ` NAVD 1988.
