This action is proposed on the following application: PROJECT NAME: WSDOT 1-405/SR 167 -Direct Connector Project PROJECT MANAGER: Clark H. Close, Senior Planner APPLICANT/CONTACT: Rob Thomas / WSDOT / 600 108th Ave NE / Bellevue, WA 98004 PROJECT LOCATION: SR 167/1-405 Interchange LEGAL DESCRIPTIONS: 1-405 MP 2.32 to 3.96 and SR 167 MP 24.80 to 26.26 SECTIONS 17, 19, 20, and 30 OF TWN 23N R 5E, SEC-TWN-R: W.M. APPLICABLE MASTER PROGRAM: City of Renton PROPOSAL DESCRIPTION: The applicant, Washington State Department of Transportation (WSDOT) Northwest Region, is requesting a Critical Areas Permit for the 1-405/SR 167 Interchange - Direct Connector Project. The project would include the construction of a new direct connector ramp for a high occupancy vehicle (HOV)/express toll lane (ETL) in each direction between SR 167 south leg high occupancy toll (HOT) lanes and 1-405 north leg HOV lanes. Included is reconstructing sections of 1-405 and SR 167 to open up the medians to make room for the new direct connector ramp; constructing a new HOV/ETL structure between SR 167 and 1-405; widening/replacing the 1-405 bridge over SR 515 (Bridge Number 405/016); installing sign bridges; installing ITS and tolling; installing and replacing noise walls; constructing storm water management facilities; constructing new retaining walls, modifying and replacing existing stream crossing(s) at SR 167 and 1-405 to improve fish passage; relocating and enhancing the channel for Rolling Hills Creek in order to provide better in -stream and riparian function; and relocating portions of East Valley Highway and S 14th Street. The Project is also part of the overall 1-405 Tukwila to Renton Improvement Project that includes consideration of existing fish barriers within the project limits. City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 2 of 26 Completion of this work would require construction of embankments, ramps, overpasses, noise walls, drainage systems, stormwater detention and treatment facilities, water mains, sanitary sewer mains and a fish passable stream crossing. In addition to the highway infrastructure, a petroleum pipeline must be relocated out of the SR 167 and 1-405 widening areas for the Direct Connector Project and future 1-405 and SR 167 projects. Project details are located in the Joint Aquatic Resources Permit Application (DARPA) form. Construction could start in 2016 and be completed in 2018 based on state funding. The project would utilize the Design Build method of delivery. The estimated cost of construction is 200,000,000 dollars. The project seeks to provide both short-term and long- term benefits, including but not limited to, improving travel speeds, improving traffic flow and safety, and improving water quality conditions. The subject site area along SR -167, that is not within road right-of-way (ROW), is zoned R-1 (Exhibit 1). There are 419 trees surveyed within the project area, all of which are either within the proposed ROW (84) or within critical areas (335). The project area includes sixteen (16) wetlands and two (2) streams, and would permanently impact 12 wetlands along the corridor totaling approximately 6.77 acres and four (4) associated wetland buffers. The project would also permanently impact one stream (Rolling Hills Creek), and temporarily impact another (East Fork Panther Creek). WSDOT would replace wetland and stream area and functions lost through compensatory mitigation. FINDINGS OF FACT: A Notice of Availability for the 1-405, Tukwila to Renton Improvement Project (1-5 to SR 169 - Phase 2) SEPA Determination of Nonsignificance and Adoption of Existing Environmental Documentation was published on April 4, 2008. 2. The applicant is requesting a Critical Area Permit from the City of Renton for the Washington Department of Transportation (WSDOT) 1-405/SR 167 Interchange Direct Connector Project. The project is located in the Water Resource Inventory Area (WRIA) 9 Duwamish- Green and WRIA 8 Cedar-Sammamish; however, the bulk of the project work occurs in the Springbrook Creek sub -basin of Water Resource Inventory Area (WRIA) 9. 4. There are three (3) tributaries to Springbrook Creek that occur within the project vicinity—Thunder Hills Creek, Rolling Hills Creek and East Fork of Panther Creek. 5. Rolling Hills Creek (Stream 09.SC2.8) flows from its headwaters southeast of the junction of 1-405 and Talbot Road, Rolling Hills Creek eventually flows northward between Talbot Road and 5 Puget Drive and into the study area approximately 200 City of Renton Deportment of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 3 of 26 feet south of 1-405. From this intersection, Rolling Hills Creek flows through a series of culverts under several commercial parking lots to where it ultimately daylights on the north side of 1-405 into an open channel between 1-405 and a parking lot associated with several local businesses including the Renton Cinema 8 and Triton Tower One. The creek then flows southerly in a culvert under the 1-405/SR 167 Interchange, into an open channel that runs parallel to the NB SR 167 to NB 1-405 ramp for approximately 520 feet, under SR 167 and local streets, then eventually outlets to Springbrook Creek. During high flow events, a portion of the flow from the section of Rolling Hills Creek between 1-405 and the Renton Cinema 8 parking lot is directed into an overflow culvert that also flows southerly under the 1405/SR 167 Interchange, before daylighting in the Panther Creek Wetlands (W 24,7R -A, B, and C). This stream contains no ESA -listed fish but potentially has resident fish including sculpin, three-spined stickleback, cutthroat trout, as well as coho salmon. 6. Between Culver 42 and 76, the existing Rolling Hills Creek channel runs along the east side of SR 167 collecting flows from a relatively small area including the undeveloped wooded Talbot Hill slope and wetland areas. The creek is characterized as a narrow channel (approximately 10 feet wide) with the SR 167 roadway embankment on the west side and wetland area on the east. 7. The East Fork of Panther Creek (09.SC-25.7) flows out of the Panther Creek Wetlands near MP 25.66 through a fully fish passable culvert (constructed by WSDOT in 2012) under SR 167. After flowing under SR 167 and East Valley Road, Panther Creek enters a large wetland complex west of East Valley Road containing forested vegetation. The creek continues through this wetland to where it flows into Springbrook Creek approximately 2,300 feet to the west. The east fork of Panther Creek has a limited stream buffer, mostly established by WSDOT as part of a previous project. This creek may be used by coho and Chinook salmon and cutthroat as rearing habitat because of its association with Springbrook Creek. 8. Proposed steelhead critical habitat is not within the action area for the Direct Connector Project. 9. There are 16 wetlands in the Direct Connector Project vicinity. The majority of them are small, palustrine scrub -shrub and emergent wetlands with limited habitat value or hydrologic function. The smaller wetlands in the project area tend to be dominated by herbaceous species or shrubs, while the larger ones have multiple plant community types. 10. The highest quality wetlands are Wetlands 24.7R -A, B, and C (Panther Creek Wetlands). The wetland complex is divided into three units by berms with cross culverts running through them. This wetland complex is over sixty acres in size and includes forested zones, as well as some permanently ponded areas dominated by aquatic bed vegetation. Common herbaceous vegetation includes reed canarygrass City of Renton Deportment of Community& Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 4 of 26 (Phalaris arundinacea), cattails (Typha latifolia) and soft rush (luncus effuses). Shrub -dominated areas typically include Sitka willow (Salix sitchensis), redosier dogwood (Cornus stolonifera) and large stands of Himalayan blackberry (Rubes ormeniacus). The remaining wetlands tend to be small and confined by adjacent impervious surfaces. 11. Wetland 2.2R -B and 2.3111 are small depressions in roadside ditches. Wetlands 2.5711 and 2.61R are spring -fed slope wetlands in a roadside ditch along a residential street. Wetland 2.31 is dominated by roadside grasses and receives hydrology SR 167 runoff. Wetland 2.2R -B is located in a deep ditch along the 1-404 off ramp to southbound SR 167 and contains a few shrubs, with a blackberry understory extending over the wetland from the steep embankments. Wetlands 25.01L and 25.7L are linear features adjacent SR 167 that provide drainage for adjacent paved surfaces. They typically have shrubby communities of alder and willow with intermittent pockets of herbaceous vegetation at the lowest elevations (ditch bottom). Himalayan blackberry is dominant in the buffers (and extending into the wetlands) of most of the wetlands in the project vicinity. Wetland 2.6R is located just south of 1-405 near Talbot Road. 1t is a small depressionaI wetland with steep sides dominated by Himalayan blackberry. The wetland includes a stand of shrubs on the west side and reed canarygrass at the lowest points. 12. The Panther Creek Wetland complex and surrounding forested upland is one of the largest unbroken habitat patches in the urban parts of greater Seattle. The area provides foraging and dispersal habitat for many migratory birds, and presumably could be suitable for yellow -billed cuckoos. However, yellow -billed cuckoos tend to avoid noisy areas, making it unlikely they would pass through this site. The project is just a mile south of the Renton Municipal Airport and includes some of the most travelled highways in the state. 13. None of the wetland areas are known to be occupied by listed fish, amphibian, or other vertebrate species. 14. There is no proposed Oregon spotted frog critical area habitat within the project action area. 15. The Rolling Hills Creek crossing under SR 167 at Mile Post 26.08 is presumed to have been constructed in 1964 as part of the original 5R 167 embankment grading contract prior. The crossing consists of a 3 foot by 4 foot box culvert (Culvert 76) and has been identified as a partial fish barrier, due to high velocities during peak flow conditions, by the Washington State Department of Fish and Wildlife (WDFW) and WSDOT Environmental Services Office (ESO). 16. To comply with federal permanent injunction number C70-9213, dated March 29, 2013, Washington State Department of Transportation (WSDOT) is proposing to City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -direct Connector Project LIJAIS-000522, CAR DATE OF PERMIT: December 4, 2015 Page 5 of 26 include a fish passable structure at State Route 167 at Milepost (MP) 25.93 for Rolling Hills Creek. 17. WSDOT evaluated the three (3) fish passage design options and concluded that the best design alternative was to use the "stream simulation" methodology. The project would replace the existing 3 foot by 4 foot, 265 foot long concrete box culvert, sloping down from east to west at 1.75 percent, with a minimum 14.7 -foot wide opening through an elliptical arch pipe. The new fish passable structure would provide a safe roadway for the traveling public. The final design would be determined by the Design -Builder contractor during final design and would assure that there is no rise in the floodplain. 18. The downstream end of the box culvert connects into the City of Renton's 60 -inch diameter storm drain system located west of SR 167, which runs under East Valley Road and SW 19th Street for approximately 3,200 feet to the outlet into Springbrook Creek. 19. Springbrook Creek conveys to the Black River Pump Station where flows are typically pumped into the Green River ("Conveyance" condition). 20. The Rolling Hills Creek and Thunder Hills Creek watershed drains 925 acres (1.45 sq. mi.) The maximum basin elevation is 400 feet and the mean basin elevation is approximately 250 feet. 21. The Panther Creek Wetlands complex, located east of SR 167, is rated as Category II wetland according to the Washington State Wetland Rating System for Western Washington, and a Category I based on the City of Renton Critical Areas Ordinance. The wetland upstream of Culvert 76 serves as floodplain storage for the channel. Replacement of Culvert 76 with a larger structure has a high likelihood of permanently altering the hydrology of the wetlands. The hydrology is currently maintained by impoundment of runoff by SR 167 and a series of culverts that equalize water levels across the berms that are oriented perpendicular to the highway. The excavation of the channel and connection to the new fish passable structure is expected to result in hydrological changes to a large portion of the wetland. The site is expected to drain more readily through the new culvert which would result in shorter periods of inundation across the wetland throughout the year. Over time, the upper portions of the wetland, above the 16' elevation, may no longer receive sufficient hydrology to support wetland vegetation. 22. The permanent loss of wetland area and functions would be mitigated off-site, utilizing credits from the approved Springbrook Mitigation Bank. 23. The proposed Culvert C76 replacement and Rolling Hills Creek channel extension would improve fish passage by: 1) Eliminating the partial fish barrier under the SR City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -direct Connector Project LUA15-000522, CAR DATE Of PERMIT: December 4, 2015 Page 6 of 26 167 highway, 2) Extending the length of channel within the northern section of the Panther Creek Wetland complex, and 3) Replacing the existing SR 167 culvert crossing with a new fish passable structure designed with stream simulation methodology (Exhibit 13). 24. The proposed new fish passable structure would be constructed on a very flat gradient to match the channel section upstream and the future channel section downstream. 25. In addition to the connection to the SW 19th Street storm drainage system, the Project would reconstruct two 36 -inch culverts through an existing utility berm (south of Culvert 76 on the east side of SR 167) that connects to Panther Creek wetland to the south. The culverts through the utility berm (to the south) assure that the hydrology is preserved in the wetland to the south of the new channel. 26. The conceptual design plan would relocate/restore the Rolling Hills Creek, starting from the south ends of Culvert Nos. 42 and 44 (Exhibit 4), and extending to the east end of the proposed new fish passible culvert crossing SR 167. The new stream would have an 11 -foot wide and 1,400 -foot long channel segment (channel length is approximate, based on conceptual design) and would be located mostly within the existing wetland on the east side of SR 167 (Exhibit 2). 27. The proposed Rolling Hills Creek channel through the proposed fish passable structure is designed to mimic the channel geometry and match the hydraulic characteristics in the existing channel. The proposed 0.27 percent sloped channel is preliminarily designed as a 5 -foot bottom width and an 11 -foot bank full (2 -year flow) width which then transitions into the existing slopes. 28. The preliminary design would maintain three existing facilities constructed as a result of the 1-405,1-5 to SR 169 Stage 1 Widening Project (Renton Stage 1) and 1- 405, I-5 to SR 169 Stage 2 Widening & SR .515 Interchange Project (Renton Stage 2) without significantly changing their contributing areas of function. Three new detention facilities would provide the additional flow control needed to mitigate the project, including: two detention ponds (i.e. SE Quadrant Detention Pond and Renton Village Detention Pond), and one detention vault (i.e. SW 23rd Street Vicinity Detention Vault). 29. Stormwater facilities for this project would maintain the peak flow rate of stormwater runoff at baseline present day conditions or better as mandated by the HRM for a range of storms from 50 percent of the 2 -year up through the 50 -year recurrent storm event. 30. The direct effects associated with the project would include filling wetlands, streams, and associated buffers. Approximately 6.77 acres of wetland would be City of Renton Deportment of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 7 of 26 permanently impacted and an additional 1.01 acres would be temporarily impacted (Exhibit 6). The functions provided by the aquatic resources being impacted would continue to be provided by Rolling Hills Creek, wetlands and associated buffers. 31. The project would create approximately 7.36 acres of new pollutant generating impervious surfaces (PGIS), approximately 19 percent over current conditions. The vast majority of runoff from new PGIS would flow into media filter drain treatment facilities, then detention ponds, and eventually Rolling Hills Creek. 32. A gas pipeline, that runs parallel to SR 167, would be relocated approximately 200 feet to the east, to remain outside the paved roadway of SR 167 through all remaining construction phases. A temporary gravel service road (includes a permanent access ramp) would be located above the relocated gas pipeline as part of the initial construction work. Public and private roadways are considered an allowed activity in wetlands and buffers within a shoreline jurisdiction, provided the criteria of RMC 4-3-090D.2.d.ix.b can be satisfied. 33. The project would include the relocation of portions of the City of Renton's water mains to accommodate the Rolling Hills Creek channel and fish passage culvert improvements. 34. There is a tall noise wall located between S 14th Street and northbound 1-405, which reduces freeway traffic noise that affects local residents. This section of 1-405 north of S 14th Street would be shifted to the south in order to accommodate the takeoff point of the new flyover ramp along southbound 1-405, and to keep the alignment forward compatible with the final build -out of the corridor, which would ultimately include one additional lane in each direction on 1-405. The shift of 1-405 to the south also precipitates the need to relocate S 14th Street, some local residences, and the noise wall. Through outreach and collaboration with local residents as part of the National Environmental Policy Act (NEPA) process, it was determined that residents in the area preferred that a visual barrier remain between 1-405 and their homes. In order to accommodate this request, the project proposes construct an earthen berm in an east/west alignment from Morris Ave South to near Talbot Road/SR 515. The location of the berm requires the placement of fill within Wetland 2.6R. A corrugated metal pipe would be placed under the berm to maintain drainage of the area toward Rolling Hills Creek to the north. The fill would impact over ninety percent of the entire wetland area, so the remaining area is also considered a permanent impact, resulting in the total loss of Wetland 2.6R, a 0.18 -acre Category III depressional wetland. 35. Because wetland and stream impacts could not be avoided, WSDOT would replace wetland and stream area and functions lost through compensatory mitigation. The project proposes to mitigate impacts through on-site restoration and the purchase of mitigation bank credits from the Springbrook Bank. Bank credits would be City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project [UA15-000522, CAR DATE OF PERMIT= December 4, 2015 Page S of 26 utilized as compensation for permanent wetland and buffer impacts. 36. The project would require the relocation of the existing sewer line in S 14th Street to be shifted approximately one-half block to the south within the proposed new alignment for S 14th Street. Stantec completed a Talbot Hill Alternatives Analysis Report, dated October 14, 2015 for the project. The change in location would make it difficult to continue to use the existing 1-405 sewer crossing at Shattuck Avenue South. Three different alternative sewer main configurations were devised and analyzed. Each alternative was evaluated based on eight project goals, including cost, schedule, level of service, environmental impact, easements, operations and maintenance, constructability/risk, and forward compatibility with WSDOT's long range master plan. According to the report, the most desirable alternative was determined to be Alternative No. 2 — Relocate the sewer from S 14th Street and redirect the sewer to flow by gravity to Smithers Ave South, and install a new trenchless sewer crossing under 1-405 at the extension of Smithers Ave S. The sewer crossing would be encased in an oversized casing throughout the WSDOT right-of-way. 37. The Alternative No. 2 alignment remains almost completely with the proposed S 14th St right-of-way, so the alignment should not cause any additional environmental impacts. However, if the contractor decides to use pipe ramming to cross 1-405, the noise level generated from the hammer may cause noise impacts. Sound barriers could be used to dampen the noise, if necessary. 38. Construction noise would extend a maximum distance of one mile from the immediate work area before attenuating to background levels. 39. As identified in the Governor's Executive Order 89-10 (Protection of Wetlands: "No Net Loss" (Order) and WSDOT Directive 31-12 (Protection of Wetlands Action Plan), WSDOT is required to create or restore wetland area and function at a minimum 1:1 mitigation ratio. 40. A Finding of No Significant Impact (FONSI) and Final Section 4(f) Evaluation by the Federal Highway Administration (FHWA), in accordance with 23 CFR 771.121, was submitted with the application, as prepared by Washington State Department of Transportation (WSDOT), dated July 2008. 41, A Wetland and Stream Assessment Report Addendum was submitted with the application, prepared by 1-405 Design -Build Office Environmental Services, dated December 2014 (updated on November 2015). 42.

Administrative Approval of Stream Relocation (RMC 4-3-050J.2.e) Stream relocation may only be permitted if associated with (RMC 4-3-050J.2.e.i): (a) A public flood hazard areas reduction/habitat enhancement project approved by ✓ appropriate state and/or federal agencies; or (b) Expansion of public road or other public facility improvements where no feasible alternative exists; or City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/5R 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 11 of 26 (c) A public or private proposal restoring a water body and resulting in a net benefit to on-site or off-site habitat and species. Staff Comment: The applicant submitted 12 documents (Findings of Fact (FDF) 40- 51), including a Finding of No Significant impact (FONSI) and Final Section 4(f) Evaluation by the Federal Highway Administration (FHWA), in accordance with 23 CFR 771.121, with the application, as prepared by Washington State Department of Transportation (WSDOT), dated July 2008. These reports concluded that the proposed project would improve public road safety, reduce congestion, and add travel capacity. The proposed action includes planning to minimize harm resulting from the project. Based on the provided information, staff believes there is no other feasible alternative to achive the intended purpose of the project. 2. Conditions applicable to stream relocation (RMC 4-3-050.1.2.e.ii.a) Compliant if condition Of approval is met Buffer widths shall be based upon the new stream location, provided, that the buffer widths may be reduced or averaged if meeting criteria of subsection I or J of this Section. Where minimum required buffer widths are not feasible for stream relocation proposals that are the result of activities pursuant to criteria in this subsection 1, other equivalent on- or off-site compensation to achieve no net loss of riparian function is provided. Staff Comment: The project, as proposed, is expected to result in temporary and permanent impacts to wetlands, streams, and buffers. The project would have permanent impacts to one stream (Rolling Hills Creek, a Type F stream), and would temporarily impact another (East Fork Panther Creek, a Type F stream). Rolling Hills Creek would be permanently filled for highway widening in the southeast corner of the 1-405/SR 157 interchange. The applicant is proposing a permanent impact of 2,420 square feet (0.06 acres) and a temporary impact of 260 square feet (0.01 acres). Stream types are defined by the Washington State Department of Natural Resources. Type F streams ore those that are known to be used by fish, or meet the physical criteria to be potentially used by fish. Fish streams may or may not have flowing water all year; they may be perennial or seasonal. Rolling Hills Creek is a Type F stream. Type F streams have a minimum critical area buffer width of 115 feet and 15 foot structure setback beyond the required buffer. The project would also permanently impact 0.92 acres of Category ii and Category iii wetlands and temporarily impact 0.14 acres to portions of five (5) wetlands (2.6R, 24.7R -B, 24.7R -C, 25.OL, and 25.7L (Exhibit 7). Where wetland and stream buffers overlapped, priority was given to wetland buffers. The only portion of the project where stream buffers were not overlapped by wetland buffers is along the day - lighted section of Rolling Hills Creek running east to west along the southbound 1-405 lanes. Because no impacts are expected in that location, all impacted buffers reported for the project were defined as wetland buffers. Existing structures such as City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 12 of 26 managed road embankments, buildings, and paved or impervious surfaces do not provide functions for adjacent aquatic resources, and were excluded from buffers. Most of the wetland buffers in the project area are limited in width and function due to adjacent structures and paved surfaces. The vegetation in the buffer impact areas is typically dominated by roadside grasses and invasive species such as Himalayan blackberry. As indicated in the Biological Assessment (May 2015), the impacts to wetlands, streams, and buffers are not expected to measurably affect ESA -listed species due to a lack of species presence. The functions provided by the aquatic resources being impacted would continue to be provided by adjacent wetlands and buffers, and Rolling Hills Creek would be relocated to the east and restored to provide better instream and riparian function than is currently present. Because wetland and stream impacts could not be avoided, WSDOT is proposing to replace wetland and stream area functions lost through compensatory mitigation. The project proposes to mitigate impacts through on-site restoration and the. purchase of mitigation bank credits from the Springbrook Bank. On-site restoration would compensate for temporary impacts to all sensitive areas, and some permanent impact due to replacement of fish passage barrier in the project area. Bank credits would be utilized as compensation for permanent wetland and buffer impacts. This project is proposing to utilize the "Design -Build" method of delivery, meaning that all of the impacts and corresponding mitigation discussed in the reports are based on low-level conceptual project design, which would be refined and finalized by a Design -Build contractor prior to construction. As identified in the Governor's Executive Order 89-10 (Protection of Wetlands: "No Net Loss" (Order) and WSDOT Directive 31-12 (Protection of Wetlands Action Plan), WSDOT is required to create or restore wetland area and function at a minimum 1:1 mitigation ratio. In order to meet temporal loss of wetland functions from long-term temporary impacts, Ecology is recommending a mitigation ratio of one-quarter of the typical ratio for permanent impacts in addition to restoring the temporary impact on-site. In any event, mitigation for impacts to wetland buffers would be regulated by the City of Renton Critical Area Regulations (RMC 4-3-050). Temporary wetland and buffer impacts would be restored on-site to improved conditions with native shrub and/or forested vegetation communities at the impact locations along the project corridor after construction. Final plans and construction details for this restoration work would be produced by the Design -Builder prior to construction. Temporary impacts to East Fork Panther Creek are not likely to result in any significant vegetation disturbance. if vegetation is disturbed, native woody species would be installed a minimum of 5 feet apart. The Design -Builder would work with WSOOT to develop a final restoration plan for temporary stream impacts prior to City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project ZUA15-000522, CAR DATE OF PERMIT; December 4, 2015 Page 13 of 26 construction. The applicant is proposing to mitigate the permanent impacts from fill in Rolling Hills Creek by relocating and enhancing the main channel to the east, and extending it approximately 1,400 feet to the south where it would cross SR 167 through a new, fully fish passable structure. Due to the proposed relocating and enhancing the main channel staff recommends, as a condition of approval, that the applicant shall purchase City -owned property and/or a permanent easement over the City's property within the Panther Creek Wetlands needed for construction of the project including the Rolling Hills Creek channel improvements and the WSDOT proposed 15 - foot fish passable culvert under SR 167 that would connect to the City's SW 19th Street storm system. WSDOT shall be responsible for the maintenance in perpetuity of the constructed Rolling Hills Creek channel, the fish passable culvert under SR 167 and the culvert connection to the City's SW 19th Street storm system, up to the point of connection to the City's SW 19th Street storm system. Likewise, the applicant would also be responsible for the relocation of the culvert within the City's right-of- way, if required. WSDOT would also be required to remove the portion of the culvert in the City's right-of-way that connects to the City storm system along East Valley Highway and reconstruct all relocated City water lines and other infrastructure in the City's right-of-way that would be impacted by WSDOT's construction of the culvert if the WSDOT culvert connection constructed in City right-of-way is no longer needed. A planning level cost estimate for relocation of existing 16 -inch City water line within SR -167 ROW at SW 19th Street is available upon request. A conceptual plan for the Rolling Hills Creek realignment and a planting plan for its restoration have been provided by WSDOT. However, the final configuration of the channel would be determined by the Design -Builder, and approved prior to construction. The basic requirements proposed by the applicant for the channel re- alignment and associated restoration, which would guide the Design -Builder, are as follows: ■ Create anew Rolling Hills Creek channel that flows from the outlet of Culvert 42 at the northbound (NB) SR 167 on-ramp to NB 1-405] to the inlet of a newly constructed fully fish passable structure at (approximately) milepost 25.932 along NS SR 167. ■ The new channel must beset back a minimum of 25 feet from the relocated Olympic Pipeline for monitoring and maintenance. ■ Size the new channel appropriately to carry the modeled 2 -year flow and should be expected to overtop during heavier storm events. ■ incorporate Large Woody Debris (LWD) into the channel according to WDFW Stream Habitat Restoration Guidelines (WDFW 2012). City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 14 of 26 ■ install native vegetation appropriate for the expected site conditions, including trees, on both sides of the channel to provide shading. Woody shrubs and trees species must be planted a minimum 25 feet from the Olympic Pipeline. The City supports an alternative design that would extend the Rolling Hills Creek channel improvements to the south and connect to the Panther Creek fish passable culvert under SR 167 that was installed by WSDOT in 2012, at approximately SW 23rd Street. However, there would be additional improvements needed to the downstream section of Panther Creek west of SR 167 to improve the existing culverts to be fish passable and to accommodate the increased flow from the Rolling Hills Creek basin in order to implement the City's preferred alternative. The City does not currently have the funds, estimated to be $6 million, to make the preferred alternative improvements west of SR 167 along the SW 23rd Street alignment. The identified Panther Creek alternative alignment could be implemented in the future when funding is available or as mitigation for a future WSDOT project. The City has submitted an application to the Fish Barriers Removal Board to improve the Panther Creek culvert crossing of East Valley Highway and will seek future funding opportunities to implement the City's preferred Panther Creek alternative to improve fish passage to the east side of SR 167 for both Panther Creek and Rolling Hills Creek instead of attempting to convert the SW 19th Street 60 -inch storm system to be fish passable. As a result of the relocation of the main channel of Railing Hills Creek to the east, the City of Renton water mains would also need to be relocated. Therefore, as a condition of approval, staff is recommending that in order to accommodate the Rolling Hills Creek channel and fish passage culvert improvements, WSDOT's selected Design -Build contractor shall be required to prepare the City water main relocation design for review and approval by the City Water Utility prior to granting permission to start construction of the water main relocation. 3. On -Site Mitigation: On-site mitigation is required unless a finding is made that on-site mitigation is not Compliant feasible or desirable. if condition Staff Comment: Because wetland and stream impacts could not be avoided and in Of order to compensate for the loss of wetland and stream resources within the Project approval area per requirements of the U.S. Army Corps of Engineers (Corps) Section 404 is met permit and the Washington State Department of Fish and Wildlife (WDFW) Hydraulic Project Approval (HPA), WSDOT is proposing to replace wetland and stream area functions through compensatory mitigation. Because wetland and City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 15 of 26 stream impacts could not be avoided, staff is recommending that any fill occurring within the FEMA 100 -year regulated flood plain be mitigated in accordance with the City's floodplain compensatory storage requirements. Compensatory storage required within the Panther Creek wetlands along the east side of SR 167 shall be based on the 1995 FEMA regulated floodplain elevation of 16.00 (NGVD 29)/19.58 (NAVD 88). The project proposes to mitigate impacts through on-site restoration and the purchase of mitigation bank credits from the Springbrook Bank. The Springbrook Bank was constructed to compensate for aquatic resource impacts in anticipation of future projects along the 1-405 and SR 167 corridors, including the Direct Connector Project. On-site restoration would compensate for temporary impacts to all sensitive areas, and some permanent impact due to replacement of fish passage barrier in the project area. Springbrook Bank credits would be utilized as compensation for permanent wetland and buffer impacts. This project is proposing to utilize the "Design -Build" method of delivery, meaning that all of the impacts and corresponding mitigation discussed in the reports are based on low-level conceptuol project design, which would be refined and finalized by a Design -Build contractor prior to construction. The applicant has indicated that the overall goal of the proposed mitigation is to replace stream and riparian functions lost by the permanent impacts to Rolling Hills Creek, while providing a fully fish passable structure under SR 167. WSDOT would achieve project mitigation goals and objectives by meeting the stated performance standards within 7 years of construction (Exhibit 9). The specific activities to achieve this goal are as follows: ■ Re -locate and restore a minimum of 520 feet of Rolling Hilis Creek. ■ Replace the existing 10 foot wide and 520 foot long segment of Rolling Hills Creek with an 11 foot wide and 1400 foot long (channel length is approximate, based on conceptual design) channel segment that would flow to a fully fish passable stream simulation crossing structure (Exhibit 10). ■ Enhance riparian function along the new channel by establishing native herbaceous and facultative and wetter woody plants. The Rolling Hills Creek Restoration Site would include riparian vegetation on both sides of the new channel where feasible. The final planting plan would maximize shading and riparian habitat to the greatest extent possible, given the constraints of the site. The final planting plan would be approved by WSDOT prior to construction. See attached performance standards for more information. City of Renton Deportment of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project ZUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 16 of 26 Monitoring procedures would be performed for up to seven (7) years after initial acceptance of the mitigation construction. Report submittals would occur in years 1, 3, and 5, with a final closeout report in year 7. Monitoring reports would be submitted to the City of Renton, WDFW, Ecology, and the USAGE, annually for review and comment. WSDOT staff would monitor the site to determine if the performance measures and success standards have been met. if the performance measures or success standards have not been met, adaptive management strategies would be deployed to achieve the final success standards. Monitoring has been proposed by WSDOT to cease as soon as all success standards have been attained. However, Renton Municipal Code (RMC) 4-3-050L.3 requires that all compensatory mitigation projects be monitored for a period necessary to establish that performance standards have been met, but generally not for a period less than five (5) years. Therefore, staff recommends, as a condition of approval, that the applicant shall submit final restoration and monitoring plans for Rolling Hills Creek, for review and approval by the Current Planning Project Manager, monitoring reports shall be submitted to the City for a period not less than five (5) years and quarterly for the first year. 4. Off -Site Mitigation: Off-site mitigation may be allowed when located within the same drainage sub - basin as the subject site and if it achieves equal or improved ecological functions over mitigation on the subject site. Staff Comment: To fully compensate for unavoidable permanent impacts to wetlands and buffers from the Project, WSDOT proposes to debit wetland mitigation credits from the Springbrook Creek Wetlond and Habitat Mitigation Bank. Compensatory mitigation for all permanent wetland and buffer impacts would be accomplished by Compliant replacing wetland functions and acreage lost by debiting credits provided at a if regulatory approved mitigation bank. Effective lune 9, 2008, the USACE (33 Code of condition Federal Regulations jCFRj Parts 325 and 332), and Environmental Protection Agency Of (40 CFR Part 230) issued a final rule that establishes a preference for the use of approval available mitigation bank credits. Since a mitigation bank must have an approved is met mitigation plan and other assurances in place before any of its credits can be used to offset permitted impacts, some of the risks and uncertainties associated with compensatory mitigation are reduced. Springbrook Bank is a large habitat restoration and wetland re-establishment site located in the city of Renton, WA, Green-Duwomish WRiA 9. The Bank was created to provide compensation for unavoidable impacts to wetlands and other aquatic resources caused by highway construction projects. The implementation of the Bank is intended to increase wetland area and encourage improved hydrologic, water City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 17 of 26 quality, and habitat functions, while facilitating environmental education opportunities along Springbrook Creek in a highly urbanized area. The Project is located entirely within the service area of the Springbrook Bank and the wetland mitigation needs of the Project correspond with the purpose, goals, and objectives of the Springbrook Bank. The objectives of the Bank are to re-establish 17.79 acres of wetland, rehabilitate 52.14 acres of wetland, enhance 32.54 acres of wetland, and enhance 7.80 acres of upland and 6.55 acres of riparian upland adjacent to Springbrook Creek for a total of 116.82 acres, the remaining acreage consists of non-credit generating buffers. The inclusion of non-credit generating buffers increases the value of the wetland credits because the presence of the wide buffer areas ensures the protection of wetland functions developed on the interior portion of the site. Purchase of wetland credits includes protection of that credit area by associated buffers, which compensates for any buffer impacts that occur on projects associated with direct wetland impacts. The restoration and enhancement activities have re -connected floodplain wetlands with Springbrook Creek, re-established wetlands, and likely improved water quality, hydrologic, floodplain, habitat, and riparian functions. Credits are the "currency" of the mitigation bank. The value of each credit is equal to its net ecological benefit. For the Springbrook Bank, the value of one credit was developed to be equal in value to 1 acre of Category 11 wetland. Specifically, the Bank requires the use of 1.0 credit per acre (1:1 ratio) of permanent Category 11 wetland impacts, 0.85 credits per acre (0.85:1 ratio) of category ill, and 0.70 acre for category iV. Credits for Category i wetland impacts do not have a standard ratio, and ore issued on a case-by-case basis. There are no Category 1 wetlands within the project footprint, so none would be impacted. For this project, the number of credits proposed to offset each impact type may deviote from the Bank requirements due to the nature of the impacts. The standard ratio is applied when an impact is occurring due to the installation of roadway elements and the Olympic Pipeline petroleum pipeline. A modified ratio is applied for impacts occurring as a result of conversion from wetlands to stream or impacts that would result in a temporal (as opposed to permanent) loss of wetland functions due to long-term vegetation disturbance. The Project meets all required criteria for use of Springbrook Bank credits for compensation of unavoidable permanent impacts to'. wetlands and buffers. Table 7, Proposed Springbrook Bank Mitigation Credits, summarizes the proposed mitigation credits to compensate for 8.238 acres of wetland impacts. The table indicates that the number of Springbrook credits required would be 6.238 (Exhibit 8). WSDOT is proposing to utilize approximately five (5) of the more than 12 credits available in the Wetland Mitigation Bank to compensate for the wetland impacts City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 18 of 26 based on recommendations from permitting agencies through early project coordination. Because the project is Design -Build, the project may be modified in a manner that results in a different required credit amount. WSDOT is proposing to provide updated impact and mitigation information prior to construction. if impacts are decreased as design is advanced and finalized by the Design -Builder, updated information may be provided to regulatory agencies to serve as the basis for a request to reduce Springbrook Bank credit use. Should the regulatory agencies approve a request to decrease the number of Springbrook Bank credits used to compensate for project impacts, an adjustment to the ledger total may be made to reflect that approval. Therefore, staff recommends, as a condition of approval, that wetland impacts be mitigated utilizing the City`s replacement ratios and code requirements, if they are more stringent than the U.S. Army Corps of Engineers (USACE) requirements. As WSDOT is proposing to use the City/WSDOT Springbrook Bank credits for mitigation associated with wetland impacts resulting from the WSDOT 1-405/SR-167 Direct Connector Project, the City, as co -manager of the Wetland Bank, must concur with the debit of credits, prior to approval by the USACE Wetland Bank Oversight Committee. S. Mitigation Type In all cases, mitigation shall provide for equivalent or greater biological functions. Additionally, there shall be no net loss of riparian area or shoreline ecological function resulting from any activity or land use occurring within the regulated buffer area. Types of mitigation include: daylighting, removal of impervious surfaces and in -stream mitigation. Daylighting (returning to open channel) of streams or removal of manmade salmonid migration barriers. Staff Comment: The permanent impact of 0.06 acres (and 520 linear feet) of Rolling Hills Creek would be mitigated on-site with the re -aligning of the creek and subsequent restoration. The low flow channel on the restoration site would be approximately 11 feet wide and 1400 feet long, resulting in a significant increase in open channel and riparian habitat along Rolling Hills Creek. See also FDF 56B for more information. 6. Development Standards No proposal shall result in a loss of critical area functions or values. If the application of these provisions would deny all reasonable use of the property, the applicant may apply for a variance as identified in RMC 4-9-250. Setbacks and buffers from critical area buffers: Type F streams require a 115 -foot buffer width and an additional 15 -foot structure N/A setback beyond the buffer.

Areas that are functionally and effectively disconnected from the wetland by a permanent road or other substantially developed surface of sufficient width and with use characteristics such that buffer functions are not provided shall not be counted toward the minimum buffer unless these areas can be feasibly removed, relocated or restored to provide buffer functions. 7. Low intensity land uses include but are not limited to the following: unpaved trails, low intensity open space (hiking, bird -watching, preservation of natural resources, etc.) and utility corridor without a maintenance road and little or no vegetation management. Staff Comment: The Critical Areas Regulations, Table 4-3-050G.2 establishes development standards for critical areas based on category or type. Completion of this work would require construction of embankments, ramps, overpasses, noise walls, drainage systems, stormwater detention and treatment facilities, water mains, sanitary sewer mains and a fish passable stream crossing. in addition to the highway infrastructure, a petroleum pipeline must be relocated out of the SR 167 and 1-405 widening areas for the Direct Connector Project and future 1-405 and SR 167 projects. Furthermore, pursuant to RMC 4-3-050C.3 "Exemptions — Critical Areas and Buffers," indicate exempt activities within critical areas and associated buffers, such as roads and utilities where critical area and required buffer impacts ore minimized and disturbed areas shall be restored. The Project, as proposed, is expected to result in temporary and permanent impacts to wetlands, streams, and buffers. Impacts to wetlands were avoided and minimized to the greatest extent feasible, including adjustment of the project footprint. Since this project includes widening, romp construction, and fish passage improvement, some impacts were unavoidable. Since no inner median exists within much of the project area, all widening must occur to the outside of the existing roadway shoulders. As a result, some of the affected wetlands would be completely filled, while others would be partially filled. The affected wetlands are along the right-of- way and/or within the median and could therefore not be avoided or minimized due to roadway design standards. All temporarily disturbed areas (vegetation that is cut and no other disturbance occurs during construction) would be restored. The majority of affected wetlands are of low quality and are dominated by non-native invasive species, such as reed canarygross, bentgrass, and blackberry. Several avoidance and minimization options still existed and were utilized in the preliminary design. The primary method of minimization is the use of over steepened slopes. Because most of the proposed embankments include Media Filter Drains (MFD), the proposed slopes are a combination of 4:1 where the MFD are proposed, and then steepened to 2:1 from there. A summary of avoidance and minimization measures is provided in Table 2 (Exhibit 5). Compliant Flood Hazard Areas: Flood hazard areas are defined as the land in the floodplain if subject to one percent (1%) or greater chance of flooding in any given year. condition Encroachments, including fill, new construction, substantial improvements, and of other development are prohibited unless certification by a registered professional City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 21 of 26 approval engineer demonstrates through hydrologic and hydraulic analyses performed in is met I accordance with standard engineering practice that: (a) Encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge; and (b) There are no adverse impacts to the subject property or abutting or adjacent properties; and (c) There are no higher flood elevations upstream; and (d) The impact due to floodway encroachment shall be analyzed using future land use condition flows. Staff Comment: The City of Renton's Municipal Code (RMC) 4-3-050 Critical Areas Regulations, backed by Executive Order 11988 Floodplain Management, require zero -rise in floodplain elevations due to construction projects. The Federal Emergency Management Agency (FEMA) found that no adverse effects to any 100 - year floodplain orfloodways would occur as a result of the proposed project. Analyses would be performed prior to placing fill to confirm that adequate mitigation has been provided. Because of this, FHWA found that no adverse effects to any 100 - year floodplains or floodways would occur as a result of the proposed project. The preliminary estimates indicated that the project would create floodplain volume up to 80,828 cubic yards at elevations 12 to 19.58 (Exhibits 11 and 12). Therefore, staff recommends, as a condition of approval, that WSDOT's Design -Build contractor shall provide a basin hydrologic and hydraulic analysis and complete a Level 3 downstream analysis of the City's SW 19th Street storm system as required in the City adopted 2009 KCSWDM and amendments from the point of connection to the SW 19th Street storm system to the ordinary high water mark of Springbrook Creek prior to construction. The backwater analysis would need to account for tailwater conditions in Springbrook Creek, including the 100 -year FEMA floodplain elevation. The Level 3 downstream analysis would need to be based upon the final design proposed by the WSDOT Design -Build contractor and developed utilizing parameters and assumptions agreed upon by the City to verify that there will not be any downstream or upstream flooding impacts in the street or adjacent properties that connect to the SW 19th Street storm system as a result of the project improvements. Impervious area impacts: Staff Comment: The Tukwila to Renton Project would add approximately 58 acres of new impervious surface. Stormwater from 154 acres of new and existing impervious area would be treated by the project for both water quality and flow control. New stormwaterfacilities would maintain existing flows by detaining stormwater (for half of the 2 -year through 50 -year storm events) prior to discharge. Water quality would be improved by routing stormwater through treatment facilities prior to discharge. This project would not degrade flow patterns or water quality from existing City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA25-000522, CAR DATE OF PERMIT: December 4, 2015 Page 22 of 26 conditions. The Federal Highway Administration (FHWA) has found that the project would have no adverse effects to surface water flows or water quality. 7. Use Regulations: a. Utilities Local utility services needed to serve water -dependent and other permitted uses within critical areas and associated buffers are subject to standards for ecological '" protection and ensure that activities do not threaten public safety, cause nuisances, or destroy or degrade critical area functions and values. Modifications to existing regional stormwater management facilities operated and maintained under the direction of the City Surface Water Utility that are designed consistent with the current version of the Washington State Department of Ecology Wetlands and Stormwater Management Guidelines or meeting equivalent objectives. New utility lines and facilities may be permitted to cross water bodies in accordance with an approved stream/lake study, if they comply with the following criteria: i. Fish and wildlife habitat areas shall be avoided to the maximum extent possible; and ii. The utility is designed consistent with one or more of the following methods: (a) Installation shall be accomplished by boring beneath the scour depth and hyporheic zone of the water body and channel migration zone; or (b) The utilities shall cross at an angle greater than sixty (60) degrees to the Compliant centerline of the channel in streams or perpendicular to the channel centerline; or if (c) Crossings shall be contained within the footprint of an existing road or utility condition crossing; and 0f approval iii. New utility routes shall avoid paralleling the stream or following a down -valley is met course near the channel; and iv. The utility installation shall not increase or decrease the natural rate of shore migration or channel migration; and v. Seasonal work windows are determined and made a condition of approval; and vi. Mitigation criteria of RMC 4-3-050L are met. Staff Comment: Staff recommends, as a condition of approval, that utilities shall be located and designed to avoid natural, historic, archaeological or cultural resources to the maximum extent feasible and mitigate adverse impacts where unavoidable. If any cultural resources are found all construction activity shall stop and the City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/5R 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 23 of 26 owner/developer shall immediately notify the City of Renton planning department, concerned Tribes' cultural committees, and the Washington State Department of Archeology and Historic Preservation. CONCLUSIONS: The proposed development is consistent with the following findings pursuant to RMC section 4-3-050: 1. A proposed action meets alternative administrative standards pursuant to this Section and the proposed activity results in no net loss of regulated riparian area or shoreline ecological function in the drainage basin where the site is located if submitted plans are followed and the conditions of approval are met. 2. Stream relocation may be allowed when analyzed in an accepted stream assessment, and when the expansion of public road or other public facility improvements where no feasible alternative exists. 3. The activity will be conducted using best management practices as specified by industry standards or applicable Federal agencies or scientific principles if submitted plans are followed and the conditions of approval are met. 4. Impacts will be minimized and disturbed areas will be immediately restored if submitted plans are followed and the conditions of approval are met. 5. Both on-site and off-site mitigation will be provided for this project if submitted plans are followed and the conditions of approval are met. 6. Compensatory mitigation projects will be monitored for a period necessary to establish that performance standards have been met, but generally not for a period less than five (5) years, if submitted plans are followed and the conditions of approval are met. 7. The cooperative agreement between the City of Renton and WSDOT for the 1-405 — SR 167 Interchange Direct Connector Project will serve as the surety device ensure performance consistent with RMC 4-1-230 (Exhibits 16 and 17). DECISION: The Critical Areas Permit and Critical Areas Exemptions are approved subject to the following conditions: 1. The applicant, Washington State Department of Transportation (WSDOT) Northwest Region, shall purchase City -owned property and/or a permanent easement over the City's property within the Panther Creek Wetlands needed for construction of the project including the Rolling Hills Creek channel improvements and the WSDOT proposed 15 -foot fish passable culvert under SR 167 that will connect to the City's SW 19th Street storm system. WSDOT shall be responsible for the maintenance in perpetuity of the constructed Rolling Hills Creek channel, the fish passable culvert under SR 167 and the culvert connection to the City's SW 19th Street storm system, up to the point of connection to the City's SW 19th Street storm system. City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/58 167 -Direct Connector Project LUAI5-000522, CAR DATE OF PERMIT: December 4, 2015 Page 24 of 26 2. The City water mains that have to be relocated, at WSDOT's expense, to accommodate the Roiling Hills Creek channel and fish passage culvert improvements shall be designed and constructed to City Water Utility standards and meet City requirements for maintenance and access. WSDOT shall require the selected design -build contractor to prepare the City water main relocation design for review and approval by the City Water Utility prior to granting permission to start construction of the water main relocation. 3. WSDOT shall be responsible for the relocation of the culvert within the City's right-of- way, if required by the City. WSDOT is also required to remove the portion of the culvert in the City's right-of-way that connects to the City storm system along East Valley Highway and reconstruct all relocated City water lines and other infrastructure in the City's right-of-way that will be impacted by WSDOT's construction of the culvert if the WSDOT culvert connection constructed in City right-of-way is no longer needed. 4. Prior to construction, the WSDOT design -build contractor shall provide a basin hydrologic and hydraulic analysis and complete a Level 3 downstream analysis of the City's SW 19th Street storm system as required in the City adopted 2009 KCSWDM and amendments from the point of connection to the SW 19th Street storm system to the ordinary high water mark of Springbrook Creek. The backwater analysis will need to account for tailwater conditions in Springbrook Creek, including the 100 -year FEMA floodplain elevation. The Level 3 downstream analysis will need to be based upon the final design proposed by the WSDOT design -build contractor and developed utilizing parameters and assumptions agreed upon by the City to verify that there will not be any downstream or upstream flooding impacts in the street or adjacent properties that connect to the SW 19th Street storm system as a result of the project improvements. 5. Wetland impacts shall be mitigated utilizing the City's replacement ratios and code requirements, if more stringent than the U.S. Army Corps of Engineers (USAGE) requirements. As WSDOT proposes to use the City/WSDOT Springbrook Creek Wetland and Habitat Mitigation Bank (Springbrook Bank) credits for mitigation associated with wetland impacts resulting from the WSDOT 1-405/SR-167 Direct Connector Project, the City, as co -manager of the Wetland Bank, must concur with the debit of credits, prior to approval by the USACE Wetland Bank Oversight Committee. 6. Any fill occurring within the FEMA 100 -year regulated flood plain as a result of the project must be mitigated in accordance with the City's floodplain compensatory storage requirements. Compensatory storage required within the Panther Creek wetlands along the east side of SR 167 shall be based on the 1995 FEMA regulated floodplain elevation of 16.00 (NGVD 29)/19.58 (NAVD 88). 7. The City's Trails Master Plan identifies the Panther Creek Wetlands as an area desirable for passive recreational opportunities — specifically a trail system that will connect into the Springbrook Trail. The project shall not preclude the possibility of such a trail being built within the Panther Creek Wetlands in the future. City of Renton Department of Community & Economic Development Critical Areas Permit WSDOT 1-405/SR 167 -Direct Connector Project LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 25 of 26 8. The applicant shall submit final restoration and monitoring plans for Rolling Hills Creek, for review and approval by the Current Planning Project Manager, monitoring reports shall be submitted to the City for a period not less than five (5) years and quarterly for the first year. 9. Utilities shall be located and designed to avoid natural, historic, archaeological or cultural resources to the maximum extent feasible and mitigate adverse impacts where unavoidable. If any cultural resources are found all construction activity shall stop and the owner/developer shall immediately notify the City of Renton planning department, concerned Tribes' cultural committees, and the Washington State Department of Archeology and Historic Preservation. DATE OF DECISION ON LAND USE ACTION: SIGNATURE: Department of Community & Economic Development It Date APPEALS: Appeals of Administrative Critical Areas Permit issuance must be filed in writing to the Hearing Examiner on or before 5:00 p.m. December 18, 2015. RECONSIDERATION: Within 14 days of the decision date, any party may request that the decision be reopened by the approval body. The approval body may modify his decision if material evidence not readily discoverable prior to the original decision is found or if he finds there was misrepresentation of fact. After review of the reconsideration request, if the approval body finds sufficient evidence to amend the original decision, there will be no further extension of the appeal period. Any person wishing to take further action must file a formal appeal within the 14 -day appeal time frame. EXPIRATION: Unless a different time period is specified in the critical area permit, construction activities, or a use or activity, for which a permit has been granted, must be commenced within two (2) years of the effective date of this critical area permit, or the critical area permit shall terminate, and a new permit shall be necessary. However, the Planning Division may authorize a single extension for a period not to exceed one year based on reasonable factors, if a request for extension has been filed with the Planning Division before the expiration date, and notice of the proposed extension is given to parties of record and the Washington State Department of Ecology. DEFINITION OF COMMENCEMENT OF CONSTRUCTION ACTIVITIES: the construction applications must be submitted, and permits must be issued before the end of the two (2) year period.

Noxious and Invasive Weeds Performance Standards Eradication of all occurrences of Class A weeds is required by state law. The Washington State Noxious Weed Control Board or a county weed board may designate certain Class B weeds for control or eradication in regions where they are not yet widespread. EXHIBIT 9 Years 1-7—Invasive weedy plant species and Washington State and King County listed noxious weeds will be managed across the site in accordance with the following standards: Noxious Weeds - Washington State -listed or King County -listed Class A weeds observed in any area of the mitigation site must be eradicated. All occurrences shall be immediately reported to the site manager and an eradication program will be initiated within 30 days of the report. King County Regulated Class B and C weeds must be controlled to prevent all seed production and dispersal of all propagative parts capable of forming new plants. King County's list requiring control includes purple loosestrife (Lythrum salicaria), musk thistle (Carduus nutans), and Scotch thistle (Onopordum acanthium). Invasive knotweeds, including Polygonum cuspidatum, P. polystachyum, and P. sachalinense must also be controlled so they do not spread. WSDOT will take extra measures to eradicate purple loostrife and polygonum species. Invasive weeds – In all 7 years, no more than 30% cover by nonnative, invasive plants except: • 20% maximum cover across the entire mitigation site for nonnative blackberry species.

Within these comments, there a specific comments that City should consider and/or respond directly: 1. We are asking for a RentonlWSDOTIMITFD planning effort to determine when and how the 1 e Avenue SW piped stream/culvert can be modified to provide fish passage, thus enabling the full benefit of WSDOT's replacement culvert under SR 167. 2. We also have a question about potential Shoreline jurisdiction under Renton's SMP for this project as the Panther Creek wetlands east of SR 167 are shown to be within the 100 year floodplain for Springbrook Creek which is a regulated shoreline waterbody. 3. We are also seeking to ensure that previous mitigation sites along SR 167 are fully protected from this project. 4. We have concerns about the proposed gas pipeline road which is located in the regulated stream buffer for Rolling Hills Creek. 5. We have concerns regarding the proposed stream design for the relocated portion of Rolling Hills Creek. 6. We are requesting a long term maintenance plan for the mitigation site, including plans for hazard trees which have been removed along SR 167 without mitigation. Please let me know if you have questions or would like to discuss further.

The revision is required so that the wetland ratings reflect the requirements of the 2015 revised Renton Municipal Code [RMC § 4-3-090 (D)(2)(d)(ii)]. The Wetland Report included a separate rating for the State and the City because the Renton Municipal Code contained its own rating system in 2007, when the wetlands in the project area were first assessed. The Panther Creek wetlands (Wetland 24.7R, in the original 2007 project documentation), were rated as Category I because Panther Creek itself was assumed to contain ESA -listed fish, while the rating for the State (Ecology Rating System, 2004) was Category II based on the scoring. The local ratings provided in the Wetland Report were carried over from the Tukwila to Renton Improvement Project Wetland Biology Report, produced in 2007. The Wetland Report also includes Information gathered from the wetland verification effort which WSDOT conducted in 2013. Through the verification process, it was determined that Wetland 24.71R should be split into 3 distinct wetland units, and rated individually using the 2004 Ecology Rating System. Each of the units (Wetlands 24.7R -A, 24.7R -B, and 24.7R -C) rated as Category 11 in 2013. Since the City now requires that wetland ratings be exclusively determined by the 2004 Ecology Rating System, the Category II rating (as determined in 2013) should apply in this case. The city should default to the Ecology Rating provided in Table 2 on Page 5 of the Wetland Report when considering the category of wetlands being impacted by WSDOTs project_ �TY www�Renton ��..

WSDOT's duties include locating, designing, constructing, improving, repairing, operating, and maintaining these state highways. The Washington State Department of Transportation (WSDOT) Northwest Region Design Build Team is pursuing the 1-405/SR 167 Interchange Direct Connector Project in order to build a new flyover ramp connecting the HOT lanes on SR 167 to the carpool lanes on 1-405 in Renton. This project was recently funded in the 2015 Connecting Washington transportation package. This letter is in response to your August 21, 2015, email containing comments received for the 1-405/SR 167 Interchange Direct Connector Project. The following text includes the original comments followed by Renton's responses. Comment #1: We are asking for a Renton/WSDOT/MITFD planning effort to determine when and how the 19th Avenue SW piped stream/culvert can be modified to provide fish passage, thus enabling the full benefit of WSDOT's replacement culvert under SR 167. Renton's Response: WSDOT has indicated that they have taken the lead in working with the City of Renton (City) and the Muckleshoot Tribe (Tribe) throughout the complete design phase, and will continue to accommodate requests and partnering opportunities within the constraints of the publically-awned roadway right-of-way and the limitations of transportation funding. Renton City Hall - 1055 South Grady Way • Renton, Washington 98057 • rentonwa.gov Ms. Karen Walter Page 2 of 4 September 15, 2015 The City does not have the budget that would be required to convert the SW 19th St drain pipe into an open channel for the foreseeable future. Additionally, the replacement of the SW 19th St storm system with a new system that is deemed fish passable to Washington Department of Fish and Wildlife (WDFW) and the Tribe's standards, is physically unattainable due to it being located in a City street and the surrounding developed properties. Comment #2: We also have a question about potential Shoreline jurisdiction under Renton's SMP for this project as the Panther Creek wetlands east of SR 167 are shown to be within the 100 year floodplain for Springbrook Creek which is a regulated shoreline waterbody. Renton's Response: City of Renton Shoreline overlay maps show that designated shoreline areas are located within 200 feet of Springbrook Creek. COR Maps, Renton's online GIS based interactive map for Renton -area information, does not show contiguous shoreline between Springbrook Creek and SR 167. The impacted wetland is separated from the 100 year floodplain for Springbrook Creek by SR 167 (a major thoroughfare) and is therefore not contiguous to Springbrook Creek Shoreline. The WSDOT 1-40S/SR 167 direct connector project will be evaluated for impacts to critical areas. Comment #3: We are also seeking to ensure that previous mitigation sites along SR 167 are fully protected from this project. Renton's Response: WSDOT has shown that they have constructed mitigation projects within the Panther Creek wetland in recent years. For example, when the Thunder Hills Mitigation project (permit NWS -200&87) was developed, the future widening of SR 167 was known. This mitigation project was designed and located to ensure that it would not be impacted by the widening project. Roadway widening occurs over extended culvert within limits accounted for when crossing was constructed. WSDOT has indicated that they preserve vegetation to every extent possible and in accordance with WSDOT policy; however, it is sometimes necessary to disturb vegetation to provide transportation safe services. Comment #4: We have concerns about the proposed gas pipeline road which is located in the regulated stream buffer for Rolling Hills Creek. Renton's Response: Public and private roadways are considered an allowed activity in wetlands and buffers within a shoreline jurisdiction, provided the criteria of RMC 4-3- 090D.2.d.ix.b can be satisfied. WSDOT has indicated that the gravel service road is a standard element associated with the Olympic Pipeline Company petroleum pipeline Ms. Karen Walter Page 3 of 4 September 15, 2015 design and work. The project would require the relocation of the pipeline to avoid widening the roadway over the existing facility. Leaving the pipeline in its existing location would require allowing access to maintain the pipeline under SR 167 traffic lanes which would impact safety and increase traffic congestion. Pipeline and Hazardous Materials Safety Administration (PHMSA) requires vegetation free right-of-way over petroleum pipeline, such that the line can be aerially inspected on a regular basis. WSDOT is carrying forward their proposed improvements in the permit documents to allow full consideration of the cumulative impacts associated with the project. The construction of the road will be reviewed under a separate construction permit. Comment #5: We have concerns regarding the proposed stream design for the relocated portion of Rolling Hills Creek. Renton's Response: Based on the proposed location, configuration, minimum design standards, planting plan, goals, objectives, and success standards, the new channel is highly likely to exceed the existing functions and habitat value provided by existing conditions. WDFW Stream Restoration Guideline have been established as a contractual Mandatory Standard by WSDOT. The conceptual stream design with details will be advanced by WSOOT to final design and will be submitted with the construction drawings for review. Staff will be recommending conditions of approval that the final design is feasible, compliant with Renton Municipal Codes, and subject to departmental compliance review. Comment #6: We are requesting a long term maintenance plan for the mitigation site, including plans for hazard trees which have been removed along SR 167 without mitigation. Renton's Response: WSDOT is proposing to achieve project mitigation goals and objectives by meeting performance standards within seven (7) years of construction. The overall goal of the applicant's proposed mitigation is to replace stream and riparian functions lost by the permanent impacts to Rolling Hills Creek, while providing a fully fish passable structure under SR 167. The Rolling Hills Creek Restoration site is proposed to be regularly maintained for a minimum of three (3) years and monitored for a minimum of five (5) years. Proposed report submittals would occur in years 1, 3, and 5, with a final closeout report in year 7 or be subject to RMC 4-3-050L. Monitoring reports would be submitted to the City of Renton, the WDFW, the Department of Ecology, and the U.S. Army Corps of Engineers, for review and comment. WSDOT staff would also monitor the site to determine if the performance measures and success standards are met. Ms. Karen Walter Page 4 of 4 September 15, 2015 WSDOT maintenance division typically consults with certified arborists in the regional landscape architectural office to determine if a tree is potentially hazardous prior to removal. If the tree is determined to be dangerous to the travelling public, the WSDOT maintenance division would remove the tree if it is found to be within the safety clear zones). Stream restoration/relocation areas proposed for this project are located in Zone 3, so these areas would not typically be disturbed by routine WSDOT maintenance The areas immediately adjacent to Olympic Pipeline would be subject to aerial inspections and they are maintained by Olympic Pipeline in a vegetation free condition, as required by the federal gas pipeline regulations. Trees that have been certified as dangerous by a registered landscape architect, certified arborist, or the City, and the City has accepted the dangerous determination per RMC 4- 4-1300.2, may be removed without a Routine Vegetation Management Permit. However, trees located within critical areas and/or their buffers need a Critical Areas Exemption for the removal of a dangerous tree. Please contact me at (425) 434-7289 if you have any questions.

E., Administrator May 22, 2008 Mr. William Jordan 1-405 Environmental Manager Washington State Department of Transportation I-405 Project Office 600 108th Avenue NE, Suite 405 Beilevue, WA 98004 RECEIVED MAY 2 7 2000 URBAN CORRIDORS OFFICE Subject: I-405, Tukwila to Renton Improvement Project (1-5 to SR 169 - Phase 2) Environmental Assessment (EA) Comments Dear Mr. Jordan: Previously, the City of Renton provided scoping comments, dated June 2006, for consideration when preparing the subject Environmental Assessment (EA). As noted in our scoping comments, the City of Renton and WSDOT have signed several letters of concurrence regarding the I-405 Master Plan for the segment between I-5 and SR 169. Continuing in our collaborative efforts on the planning and design of improvements to the I-405 corridor, the City of Renton submits the following comments for consideration with regard to the I-405, Tukwila to Renton Improvement Project (Phase 2) Environmental Assessment. APPENDICES We recommend that the letters of concurrence noted above be included or referenced in Appendix B -- Agency and Tribal Correspondence. CHAPTER 3 — DEVELOPING TIIE ALTERNATIVES The EA notes the cantilever of I-405 over Main Avenue South. The City would like the EA to note what, if any, unique impacts this may cause to the ownership, operations, and maintenance of different rights-of-way stacked in airspace. It is expected that during future project development, the City and WSDOT will need to develop ownership, operations, and maintenance agreements. 1055 South Grady Way - Renton, Washington 98057 ENTO William Jordan. 1-405 Environmental Manager May 22, 2008 Page 2 CHAPTER 5.2 -- NOISE The City recommends that noise walls be included to mitigate impacts to the City's Tri -Parks complex, the City's historical museum, and the City's main library. The EA identifies that these parks, the museum, and library already exceed the noise level, and in the case of Cedar River Park, the noise level will increase. Development of the Cedar River Vicinity Charette was based on the understanding that in order for the northbound 1-405 to SR 169 off -ramp to be moved significantly closer to the Renton Community Center, this ramp would include a noise wall. CHAPTER 5.3 — COMMUNITIES, BUSINESSES, AND PUBLIC SERVICES The EA should address impacts to private houses on Mill Avenue South where the proposed stacked Mill Avenue is proposed, such as subterranean impacts. CHAPTER 5.4 — RECREATIONAL AND CULTURAL. RESOURCEs The Cultural Resources discipline report should have an additional description regarding the protection of the Renton Coal Mine Hoist Foundation, located between Benson Road and the 1-405 southbound off -ramp to SR 515. The text should not indicate that the mine hoist foundation will be removed. The City requests the Cultural Resources discipline report evaluate the Longacres horsetrack monuments located underneath 1-405 just east of the BNSF railroad tracks. Regardless of the results of this analysis, the City would like WSDOT to commit to c000rdinating with the City in the future regarding the protection or relocation of these monuments. The Panther Creek Wetlands Opens Space, as identified in the City of Renton 2003 Long -Range Park, Recreation, and Open Space Plan, shows this area to be developed in the future to include a boardwalk with interpretive materials, viewpoints and trails systems. In addition, the City's adopted Trails Master Plan designates this area as a trail location connecting west to the Springbrook Trail and east to the Cascade "frail. While not currently open to the public, this will be a major connection to trails to the east and west. The City requests the EA identify this connection under SR 167. This should be designated as a 4(f) property. The Cedar River Natural Area was acquired with Washington Wildlife and Recreation Programs (WWRP) funding administered by the Resource and Conservation Office (RCO) along with the NARCO property. This was completed as one acquisition; $500,000 was granted by the RCO. This property should be listed as a 4(f) parcel throughout the EA. The EA defines a "constructive use," and on page 5-48 indicates that noise, visual quality, and air quality studies were completed for the Tukwila to Renton Project EA and the studies found that the project would not have constructive uses at any of the recreational properties. The City H:IFile Sys1TRP - Transportation Planning & ProgramtninffRP-10 - Transportation Planning Projects\WSDOT 1-40515 Rentonl'TRiP +EA COmment5l7RIP EA Comments May 19 2008.doc William .lordan, 1-405 Iinvironmental Manager May 22, 2008 Page 3 disagrees with this conclusion. The City requests noise barriers to be constructed to reduce the increased impacts and noise to the City's Tri -Park complex, museum, and library. CHAPTER 5.5 — VISUAL QUALITY The EA should also include text regarding the significant effect on visual quality caused by the cantilever of I-405 over Main Avenue South. CHAPTER 5.6 — WATER RESOURCES WSDOT needs to work out a schedule to provide the City with the requested information and relevant studies depending on project funding. The City's existing underground utilities in the Tri -Parks vicinity will be severely impacted by the project, especially by the new ramp and support structures. The EA should identify these impacts and WSDOT's commitment to relocate the City's existing utilities, including but not limited to: water mains, sanitary and storm sewer mains, chemical lines for water treatment, telemetry and power conduits, and vaults. The EA should identify that WSDOT will commit to relocation of these utilities prior to any condemnation and/or conversion of acquired City -owned property to limited access right-of-way. As part of the EA, WSDOT should identify the need for the acquisition of a new utility corridor for the relocation of.the existing City utilities impacted by the project. Should you have any questions or concerns, please contact Keith Woolley, the City's 1-405 coordinator, at (425) 430-7318. Sincerely, 4 �'--� Gregg immerman, P.E.

Upon further discussion with WSDOT, the City has determined that the Panther Creek Wetland Open Space would likely only be developed with a multiuse trail if construction occurs for a regional detention within the complex as stated in our 2003 Parks, Trail, and Open Space plan. At this time, we do not consider the Panther Creek Wetland Open Space Area to meet the criteria for a Section 4(f) Resource. We have also discussed with WSDOT additional details regarding the Cedar River Natural Area. There are two parcels of land acquired by the City from Puget Sound Energy through a quit claim deed. These parcels are encumbered by utility easements and are not part of the Cedar River Natural Area. The effects on the Narco property and associated mitigation as described in WSDOT's Draft Section 4(f) Evaluation are accurate. No additional effects on the Cedar River Natural Area are expected.

The letter requests that the Washington State Department of Transportation (WSDOT) design the I-405 Corridor Program roadway improvements so as not to preclude the introduction of a trail in the Panther Creek. Wetlands area. WSDOT recognizes that the needs of both the Renton Community Services Department and WSDOT can be accommodated within the sizable area of the Panther Creek Wetlands. Therefore WSDOT believes that with the continuing coordination between WSDOT and the City of Renton, the roadway improvement can be designed so as not to preclude the introduction of a trail in this area. This coordination would include the City of Renton keeping WSDOT informed as soon as more specific development plans for the proposed trail are advanced. I hope this letter satisfies the City of Renton's concerns in this matter.

I wish to clarify the question of the significance of the Panther Creek Wetlands as a local recreational resource. As you are aware, there are currently no local recreational facilities or amenities located in the Panther Creek Wetlands. We neither have immediate plans nor have identified funding to construct recreational facilities in this area. At this time we would not consider the Panther Creek Wetlands to be a recreational resource of local significance. Our Trails Master Plan identifies the Panther Creek Wetlands as an area desirable for passive recreational opportunities — specifically a trail system that will connect into the Springbrook Trail. While no such trail exists and we have not yet determined if — or whether — such a trail will be built, we do not wish to preclude the possibility of such a trail being built in the future. I believe that the needs of the Renton Community Services Department and the State Department of Transportation could be accommodated by recognizing that the proposed improvements to 1-405 and SR 167 and a trail could easily co -exist within this sizable area. Our concerns would be satisfied upon receipt of a letter from the Department of Transportation stating that the roadway improvements in this area will be designed so as not to preclude the introduction of a trail in this area at some future date. This issue could then be further investigated by our two agencies at the time when project -specific improvements are developed. I hope this letter clarifies the issue. Thank you.

The project would include the construction of a new direct connector ramp for a high occupancy vehicle (HOV)/express toll land (ETL) in each direction between SR 167 south leg HOT lanes and 1-405 north leg HOV lanes. Included is reconstructing sections of 1-405 and SR 167 to open up the medians to make room for the new direct connector ramp; constructing a new HOV/ETL structure between SR 167 and 1-405; widening/repiacing the 1-405 bridge over SR 515 (Bridge Number 405/016); installing sign bridges; installing ITS and tolling; installing and replacing noise walls; constructing storm water management facilities; constructing new retaining walls, modifying and replacing existing stream crossing(s) at SR 167 and 1-405 to improve fish passage; relocating and enhancing the channel for Rolling Hills Creek; and relocating portions of East Valley Highway and S 14th Street. The Project is also part of the overall 1-405 Tukwila to Renton Improvement Project that includes consideration of existing fish barriers within the project limits. Construction could start in 2016 and be completed in 2018 based on state funding. The project would utilize the Design Build method of delivery. The estimated cost of construction is 200,000,000 dollars. The subject site area along 5R-167, that is not within road right-of-way (ROW), is zoned R-1. There are 419 trees surveyed within the project area, all of which are either within the proposed ROW or within critical areas. The project site includes work within wetland and streams, and would permanently impact 10 wetlands totaling approximately 6.8 acres and four (4) associated wetland buffers.

The following briefly describes the application and the necessary Public Approvals. DATE OF NOTICE OF APPLICATION: August 7, 2015 LAND USE NUMBER: LUA15-000522, CAR PROJECT NAME: WSDOT 1-405/SR 167 -Direct Connector Project PROJECT DESCRIPTION: The applicant, Washington State Department of Transportation (WSDOT) Northwest Region, is requesting a Critical Areas Permit for the 1-405/SR 167 Interchange - Direct Connector Project. The project would include the construction of a new direct connector ramp for a high occupancy vehicle (HOV)/express toll land (ETL) in each direction between SR 167 south leg HOT lanes and 1-405 north leg HOV lanes. Included is reconstructing sections of 1-405 and 5R 167 to open up the medians to make room for the new direct connector ramp; constructing a new HOV/ETL structure between SR 167 and 1-405; widening/replacing the 1-405 bridge over 5R 515 (Bridge Number 405/016); installing sign bridges; installing ITS and tolling; installing and replacing noise walls; constructing storm water management facilities; constructing new retaining walls, modifying and replacing existing stream crossing(s) at SR 167 and 1-405 to improve fish passage; relocating and enhancing the channel for Rolling Hills Creek; and relocating portions of East Valley Highway and 5 14th Street. The Project is also part of the overall 1-405 Tukwila to Renton Improvement Project that includes consideration of existing fish barriers within the project limits. Construction could start in 2016 and be completed in 2018 based on state funding. The project would utilize the Design Build method of delivery. The estimated cost of construction is 200,000,000 dollars. The subject site area along SR -167, that is not within road right-of-way (ROW), is zoned R-1. There are 419 trees surveyed within the project area, all of which are either within the proposed ROW or within critical areas. The project site includes work within wetland and streams, and would permanently impact 10 wetlands totaling approximately 6.8 acres and four (4) associated wetland buffers. The project would also permanently impact one stream totaling 2,613 square feet. The applicant submitted the following reports: Wetland and Stream Assessment Report, 2015 Biological Assessment Update, Geotechnical Baseline Report, Drainage Report, and Preliminary Hydraulic Design Analysis for Rolling Hills Creek Realignment. PROJECT LOCATION: SR 167/1-405 Interchange DETERMINATION OF NON -SIGNIFICANCE: As the lead agency for this proposal, the Washington State Department of Transportation has determined that the improvement to Interstate 405 (1-405), Tukwila to Renton Improvement Project (1-5 to State Route (SR) 169 — Phase 2) does not have a probable significant adverse impact on the environment on March 31, 2008. An environmental impact statement (EIS) is not required under RCW 43.21C.030(2)(c). The Federal Highway Administration (FHWA) served as lead agency under the National Environmental Policy Act (NEPA) for the 1-405, Tukwila to Renton Improvement Project (I-5 to SR 169—Phase 2). WSDOT prepared an Environmental Assessment (EA) and Draft Section 4(f) Evaluation in compliance with NEPA, 42 United States Code (USC) Section 4321 et seq.; FHWA regulations, 23 Code of Federal Regulations (CFR) Part 771; and the State Environmental Policy Act (SEPA). On July 18, 2008 and after carefully considering the EA, supporting documents, and the public comments and responses, FHWA found under 23 CFR 771.121 that the proposed project, with the mitigation to which WSDOT has committed, will not have any significant adverse effect on the environment. A copy of the Finding of No Significant Impact (FONSI) and Final Section 4(f) Evaluation are available to the public on request.

Project Proposal: The proposed project is seeking to construct a ramp for a high occupancy vehicle (HOV)/express toll lane (ETQ vehicles in each direction between SR 167 south leg HOV (HOT) lanes and 1-405 north leg HOV lanes. Per the applicant, Critical Areas studies available at: ftp://ftp.wsdot.wa.gov/incoming/1-405 SR 167 Direct Connector. The SR 167/1- 405 Interchange Direct Connector project is part of the staged implementation of the project studied in the 2008, 1-405 Tukwila to Renton Improvement Project (TRIP) Environmental Assessment. The project activities will occur on and adjacent to the highway from SR 167 milepost (MP) 24.80 north to 1-405 MP 3.96. The project is located in Water Resource inventory Area (WRIA) 9 Duwamish-Green and WRIA 8 Cedar-Sammamish. The project is within sections 17, 19, 20, and 30 of Township 23, Range 5 East, W.M. A pre -application meeting is being requested to assist WSDOT's team with identification of environmental permit application requirements. Project elements include: ■ Reconstructing sections of the 1-405 and SR 167 mainline roadways to open up the medians to make room for the new direct connector ramp; 0 Construction of a new HOV/ETL structure between SR 167 and 1-405; D.O.T. 405/167 Direct nector Page 2 of 4 December 22, 2015 ■ Widening/replacing the 1-405 bridge over SR 515 (Bridge Number 405/016); ■ Constructing new retaining walls and relocating a noise barrier; ■ Modification of local roadways, including East Valley Road and S. 14th Street, related to the interchange improvements and 1-405/SR167 widening; ■ installation of new sign bridges, ITS, and tolling; ■ Installation/re-location of noise walls; ■ Construction of new storm water management facilities; ■ installation of a new stream crossing at SR 167 to improve fish passage. ■ Relocation of four main utilities: Olympic Pipeline Company underground petroleum products pipelines; City of Renton sanitary sewer; City of Renton water supply main; and Puget Sound Energy overhead high voltage power transmission line. Project details are located in the Joint Aquatic Resources Permit Application (JARPA) form. Current funding provides for preliminary design, environmental re-evaluation, completion of necessary permits, and right-of-way acquisition. Additional funding is needed to complete the construction. Current Use: Current and proposed use of the site is a portion of a transportation corridor linking the cities along the east side of Icing County. The project uses existing roadway right- of-way to every extent possible; however, some property acquisitions are necessary, along S 14th Street, S. 15th Street, Shattuck avenue South and Whitworth Avenue South. Portions of commercial parking areas and landscaped areas will also be purchased. On August 27, 2013 the City of Renton granted a modification of the reconstructed street section of East Valley Road in order to accommodate the 1-405/SR 167 Direct Connector project improvements. Land Use/Zoning: The area is WSDOT right-of-way near 1-405/SR167 or City of Renton right- of-way, commercial parking lots and landscaped areas (future right-of-way). Critical Areas: The project area includes 14 wetlands and two streams. Some impacts to the project area wetlands and associated buffers will be avoided. Since this project includes widening, ramp construction and fish passage improvement, some impacts were unavoidable. The project, as proposed, is expected to result in temporary and permanent impacts to wetlands, streams, and buffers. It is the applicant's responsibility to ascertain all critical areas present on the site. The applicant has indicated that the proposed project will directly affect 9 wetlands along the project corridor, some of which will be completely filled. A total of 3.60 acres (0.42 indirect permanent, 1.17 permanent conversion, and 1.23 long-term temporary) of permanent wetland impacts due to fill or excavation will occur as a result of this project. The relocation of existing utilities out of critical area and its buffer; the modification of existing utilities and streets by 10% or less; or the construction of new streets, roads, rights- of-way and associated appurtenances, facilities and utilities where no alteration or additional fill materials will be placed other than the minimum alteration and/or fill needed H:\CED\PIanning\Current Plan ning\PREAAPPS\15-000009 D.O.T. 405/167 Direct Connec— Page 3 of 4 December 22, 2015 to restore those facilities or to construct new trails to meet established safety standards are exempt activities permitted within critical areas and associated buffers per RMC 4-3- 050C.5.e.

(d) Only required when project is located in designated floodplain. The applicant indicated that there will be permanent impacts to one stream (Rolling Hills Creek), and may temporarily impact another (East Fork Panther Creek). Rolling Hills Creek will be permanently filled for highway widening in the southeast corner of the 1405/SR 167 Interchange, approximately 520 feet. Impacts to steams, wetlands and/or their buffers would need to provide a conceptual mitigation plan. H.\CED\Planning\Current Planning\PREAPPS\15-000009 D.O.T. 405/167 Direct ector Page 4 of 4 December 22, 2015 Environmental Review: Based on the scope of the project Environmental (SEPA) Review is required. Floodplain: A flood hazard assessment will be required. No reduction in floodplain conveyance, both onsite and on adjacent properties, during 100 -year flood event ("zero -rise" floodplain). Pursuant to RMC 4-5-120 all properties located within a floodplain are required to provide a biological assessment. Projects with the potential to impact fish (Chinook salmon, bull trout), unexpected, new, rare or other endangered species habitat (bald eagles) shall provide a biological assessment/critical area study. The purpose of this assessment is to determine whether a proposed action is likely to: (1) adversely affect listed species or designated critical habitat; (2) jeopardize the continued existence of species that are proposed for listing, or unexpected, new or rare species; or (3) adversely modify proposed critical habitat. A biological assessment/critical area study evaluates the proposal, all probable impacts and risks related to the critical area, and recommends appropriate mitigation measures to adequately protect the functions and values of the critical area, and preserve anadromous fish and their habitat. Should the assessment include unanticipated mitigation recommendations for the applicant shall be required to comply with such recommendations. The applicant is proposing to fill within an existing floodplain, therefore compensatory storage must be provided in order to mitigate proposed fill imported into the floodplain. At a minimum, equal amount of compensatory storage must be provided (no net fill). Projects that propose fill within a floodplain are required to provide a FEMA NFIP Biological Opinion (BiOp). BiOps are prepared under the Endangered Species Act (ESA), and evaluate whether projects or programs are likely to harm the survival and recovery of an endangered species. They also include "reasonable and prudent alternatives" that must be implemented. Permit Requirements: The proposed project would require Critical Areas Variance in order to relocate 520 feet of the Rolling Hills Creek, A Critical Area Exemption to relocate four major utilities (provide distances to residential buildings), Right-of-way Use Construction Permit, and Environmental (SEPA) Review. All land use permits would be processed within an estimated time frame of 12 weeks. Detailed information regarding the land use application submittal is provided in the attached handouts or is also available on the City's website. Fees: There is no fee for Critical Area Exemption. The fee for a Critical Areas Variance is $1,200.00 (per each variance requested). The application fee for SEPA Review (Environmental Checklist) is $1,000. A 3% technology surcharge fee would also be assessed at the time of land use application. Note: When the formal application materials are complete, the applicant is strongly encouraged to have one copy of the application materials pre-screened at the 6th floor front counter prior to submitting the complete application package.

The modification is needed as the Direct Connector project as proposed would not meet the City's Complete Street Standards (RMC 4-6-060F.2) for East Valley Road, between SW 16th Street and SW 19th Street. Staff from City Departments have reviewed and discussed your request and have determined that the modification may be granted resulting in the following street section: The section of East Valley Road will have two 11 -foot wide lanes, and one 12 -foot wide turn lane for East Valley Road (34 feet total from the face of curb to the face of curb) and a reduced planter width of 7 feet. However, this recommendation is conditioned upon WSDOT providing assurance that this cross section will be forward compatible with the 1-405 Master Plan Improvements, and that no further relocation of East Valley Road will be needed. This would allow final placement of East Valley Road from SW 16th Street to SW 19th Street and avoid further disruption to businesses in the future. Therefore, the requested modification is approved, subject to the following condition: WSDOT must provide written assurance to the City of Renton that the approved cross section (two 11 -foot wide lanes, one 12 -foot wide turn lane, and a 7 -foot wide planting strip) will be forward compatible with the 1-405 Master Plan Improvements and that no further relocation of East Valley Road will be needed. The decision to approve the proposed modification is subject to a fourteen (14) day appeal period frorn the date of this letter. Any appeals of the administrative decision must be filed with the City of Renton Hearing Examiner by 5:00 p.m., September 10, 2013.

The purpose of this submittal package is to document the projects consistency with Critical Areas Exemption requirements as outlined in the City of Renton Critical Areas Ordinance. The proposed project will utilize the Design Build method of delivery. Any further permits or approvals required to complete construction of the proposed project will be initiated after WSDOT selects a Design Build contractor to complete the remaining work. Project Narrative The Project will construct a new direct connector ramp for a high occupancy vehicle (HOV)/express toll lane (ETL) in each direction between SR 167 south leg HOT lanes and I-405 north leg HOV lanes. Replacing an existing culvert crossing of SR 167 with a fish passable structure and a relocated/enhanced channel for Rolling Hills Creek. Current funding provides for preliminary design, environmental documentation, completion of necessary permits, and right of way acquisition. Additional funding is required to complete final design and construction. If construction funding becomes available, construction could start in 2016 and be completed in 2018. The estimated total cost of construction is $200,000,000.00 US Dollars. The Project includes work within wetland and streams, and will permanently impact ten wetlands (totaling approximately 6.8 acre), and four associated wetland buffers. To compensate for these impacts, WSDOT proposes wetland mitigation at the Springbrook Creek Wetland and Habitat Mitigation Bank. The Project will also permanently impact one stream (totalipg.0.06,acre). To JUL 10 2015 compensate for this unavoidable permanent impact, WSDOT proposes stream mitigation at the Rolling Hills Creek Restoration Site, adjacent to the impacted stream. The project includes relocating portions of East Valley Highway and South 14th Street, which includes utility work, and sidewalk construction. An assessment of trees within the project footprint was conducted by project biologists. The project area was divided into seven zones which were systematically inspected for trees greater than six inches diameter at breast height. The findings from the assessment are attached. All of the trees that will be potentially impacted by the project are within critical areas or will be impacted due to the construction of public roads.

The existing Rolling Hills Creek section near the I-405 northbound onramp from northbound SR 167 is confined to an incised channel against the highway embankment. There are no feasible design options to provide the needed highway improvements that won't impact this section of stream. Furthermore, the project is required by federal court injunction, to replace the Rolling Hills Creek culvert under SR 167 with a fish passable structure that meets current WDFW water crossing design guidelines. Meeting the injunction requirements also requires a level of impact to the stream. The project will provide the needed transportation improvements and meet the court injunction requirements in an environmentally beneficial manner. A new, appropriately sized, stable stream channel is proposed to the east of the SR 167 widening. This channel will be approximately 1,400 feet long, and will replace the existing 520 foot channel, resulting in nearly 900 additional feet of daylighted stream, which improves fish habitat function. The south end of the channel will connect to a fully fish passable stream crossing under SR 167, which will improve opportunities for fish access from Springbrook Creek downstream.

These improvements are a part of the 1405 Corridor Program. The proposed action includes the following improvements to support construction and operation of the facility: • Add capacity to both 1405 and SR 167; • Reconstruct bridges over the Green River and Cedar River, and add one new bridge over the Green River; • Modify the SR 181 and SR 169 interchanges; • Reconstruct the SR 167 interchange, including a new general-purpose direct -connector ramp from southbound I.405 to southbound SR 167, HOV direct -connector ramps from northbound SR 167 to northbound 1405 and from southbound 1405 to southbound SR 167, and a split -diamond interchange on 1-405 at Lind Avenue and Talbot Road (SR 515) with connecting frontage roads; and • Reconstruct the two local street accesses to Renton Dill. Other features of the project include: • Stripe lanes to provide a buffer between HQV and general-purpose lanes along portions of 1405 and SR 167; • Construct several retaining walls to accommodate the project; • Construct stonnwater management facilities to provide water quality treatment and detention and upgrade the conveyance system; • Implement context -sensitive solutions during the project; • Implement measures that avoid or minimise effects to the environment; • Use Spriingbrook Creek Wetland and Habitat Mitigation Bank for wetland mitigation; • Construct a noise barrier approximately 1, 100 feet long and 20 feet high along northbound 1-405 just north of the Benson Road; • Construct a noise barrier approximately 2,200 feet long and 20 feet high along the northbound 1-405 from just north of Thunder Hills Creek to the Renton Avenue bridge over 1405; and • Reduce the eastern end of the proposed Talbot Hill noise barrier that is discussed in the Renton Nickel Improvement Project Environmental Assessment by approximately 300 feet. The Tukwila to Renton Improvement Project will provide many short- and long-term benefits. Some of these benefits are: V I 167 Interchange - Direct Connector Project JHRPA Form Attachment 14 • Improving travel speeds between 1-5 and SR 169 by approximately 10 to 15 miles per hour by 2014; • Improving traffic flow and safety by limiting access points to the H.OV lanes with a striped buffer; and • Improving water quality conditions in the project area by treating approximately 200 percent of the new impervious surfaces. Proponent: Washington State Department of. Transportation Location o, f current preposal: The I405, Tukwila to Renton Improvement Project (I-5 to SR 169 - Phase 2) extends for apprroximately 4 miles along 1.405 (Tnilepost 0.0 to milepost 4.1) from the 1-5 interchange to the SR 169 interchange. Also, the project extends south on SR 167 for approximately 2.0 miles (milepost 24.4 to 26.3) from I-405 to SW 43rd Street. Title and Description of documents being adopted.- 1-405, dopted.

This memo provides a brief project overview, an assessment of impacts to wetlands, streams, and their associated buffers, and a summary of proposed restoration of temporary impacts and compensatory mitigation for unavoidable permanent impacts to aquatic resources. This project will utilize the "Design -Build" method of delivery, meaning that all of the impacts and corresponding mitigation discussed herein are based on a low-level conceptual project design, which will be refined and finalized by a Design -Build contractor prior to construction. Proiect Location The Project is located at the junction of Interstate 405 (I-405) and State Route (SR) 167, in the City of Renton, Washington (Figure 1). The project activities will occur on and adjacent to the highway from SR 167 milepost (MP) 24.80 north to I-405 MP 3.96. The project is located in Water Resource Inventory Area (WRIA) 9 Duwamish-Green and WRIA 8 Cedar-Sammamish. The project is within sections 17, 19, 20, and 30 of Township 23, Range 5 East, Willamette Meridian. Proiect Description Primary elements include a direct connector ramp for high occupancy vehicles (HOV) in each direction between the SR 167 south leg High Occupancy Toll (HOT) lanes and the I-405 north leg HOV lanes. Completion of this work will require construction of embankments, ramps, overpasses, noise walls, drainage systems, stormwater detention and treatment facilities, and a fish passable stream crossing. In addition to the highway infrastructure, a petroleum pipeline must be relocated out of the SR 167 and 1-405 widening areas for the Direct Connector Project and future I-405 and SR 167 projects. Project details are located in the Joint Aquatic Resources Permit Application (JARPA) form. r i lake 1+Vsshin" N sR � 1-406/SR 167 Direct Connector Project Area WR6% B wsu►g SR no SRI Proposed Stream Renton 1.405 Mitigation Site Roiling Hills Creek Bast Fork Panther Creek sa WOSpringbrook Creek SR 16 Springbrook Creek Wetland Milgation Bank Figure 1. Project Area Map. 2 Existing Conditions of Sensitive Areas Fourteen wetlands and two streams, listed in Table 1, are Iocated within the Project area and referenced in this memorandum according to the naming convention established by the Tukwila to Renton Improvement Project. Additional detailed descriptions of the affected environment are provided in the Wetland Biology Report and Addendum (WSDOT 2014). The smaller wetlands in the project area tend to be dominated by herbaceous species or shrubs, while the larger ones have multiple plant community types. Wetlands Wetland 24.7R is divided into three units (A, B, and C) by berms with cross culverts running through them. This wetland complex is over sixty acres in size and includes forested zones, as well as some permanently ponded areas dominated by aquatic bed vegetation. Common herbaceous vegetation includes reed canarygrass (Phalaris arundinacea), cattails (Typha latifolia) and soft rush (Juncus effuses). Shrub -dominated areas typically include Sitka willow (Salix sitchensis), redosier dogwood (Cornus stolonifera) and large stands of Himalayan blackberry (Rubus armeniacus). An additional 7 wetlands will be impacted by the project. These impacted wetlands tend to be small and confined by adjacent impervious surfaces. Wetland 2.2R -B and 2.31R are small depressions in roadside ditches. Wetland 2.31 is dominated by roadside grasses and receives hydrology SR 167 runoff. Wetland 2.2R -B is located in a deep ditch along the I-404 off ramp to southbound SR 167 and contains a few shrubs, with a blackberry understory extending over the wetland from the steep embankments. Wetlands 25.OL, 25.7L, and 25.81, are linear features adjacent SR 167 that provide drainage for adjacent paved surfaces. They typically have shrubby communities of alder and willow with intermittent pockets of herbaceous vegetation at the lowest elevations (ditch bottom). Himalayan blackberry is dominant in the buffers (and extending into the wetlands) of most of the wetlands in the project vicinity. Wetland 2.6R is located just south of I-405 near Talbot Road. It is a small depressional wetland with steep sides dominated by Himalayan blackberry. The wetland includes a stand of shrubs on the west side and reed canarygrass at the lowest points. Streams There are two streams that flow through the project area (Table 1). Rolling Hills Creek (Stream 09.SC-2.8) and East Fork Panther Creek (Stream 09.SC-25.7) are small urban streams that are heavily manipulated as a result of development in and around the City of Renton. Stream locations within the project area can be seen in Attachment 1 (Impact Plan Sheets). From its headwaters southeast of the junction of I-405 and Talbot Road, Rolling Hills Creek eventually flows northward between Talbot Road and S Puget Drive and into the study area approximately 200 feet south of I-405. From this intersection, Rolling Hills Creek flows through a series of culverts under several commercial parking lots to where it ultimately daylights on the north side of I-405 into an open channel between I-405 and a parking lot associated with several local businesses including the Renton Cinema 8 and Triton Tower One. The creek then flows south in a culvert under the I-405/SR 167 Interchange, into an open channel that runs parallel to the NB SR 167 ramp to NB I-405 for approximately 520 feet, under SR 167 and local streets, that eventually outlets to Springbrook Creek. During high flow events, a portion of the flow from K the section of Rolling Hills Creek between 1-405 and the Renton Cinema 8 parking lot is directed into an overflow culvert that also flows south under the I-405/SR 167 Interchange, before daylighting in the Panther Creek Wetlands (W 24.7R -A, B, and Q. The East Fork of Panther Creek flows out of the Panther Creek Wetlands near 1-405 MP 25.66 through a fully fish passable culvert (constructed by WSDOT in 2012) under SR 167. After flowing under SR 167 and East Valley Road, Panther Creek enters a large wetland complex west of East Valley Road containing forested vegetation. The creek continues through this wetland to where it flows into Springbrook Creek approximately 2,300 feet to the west. The east fork of Panther Creek has a limited stream buffer, mostly established by WSDOT as part of a previous project. This creek may be used by coho and Chinook salmon and cutthroat and steelhead trout as rearing habitat because of its association with Springbrook Creek. Table 1.

Since this project includes widening, ramp construction, and fish passage improvement, some impacts were unavoidable. Since no inner median exists within much of the project area, all widening must occur to the outside of the existing roadway shoulders. However, several . avoidance and minimization options still existed and were utilized in the preliminary design. The primary method of minimization is the use of over steepened slopes. Because most of the proposed embankments include Media Filter Drains (MFD), the proposed slopes are a combination of 4:1 where the MFD are proposed, and then steepened to 2:1 from there.

Impacts to Aquatic Resources and Buffers The Project, as proposed, is expected to result in temporary and permanent impacts to wetlands, streams, and buffers. Permanent impacts occur when a wetland is filled or excavated so that it becomes non -wetland. These impacts typically occur from cut and fill activities. Permanent impacts can occur indirectly, when projects result in reduction or elimination of wetland functions in the remaining wetland area, or alterations to surface water flows separate the remnant wetland from its hydrologic source and prevent it from maintaining wetland hydrology. Reduction of wetland functions occur when the wetland area is reduced to an extent that it is unable to provide some or all of its pre -disturbance functions. Typically impacts are considered temporary when only vegetation is cut and no other disturbance occurs during construction. Grubbing or soil disturbance is typically considered a permanent impact and is evaluated on a case-by-case basis. Potential impacts to wetlands were assessed using construction footprints, cut and fill lines and cross-sections showing existing and proposed grades. Construction footprints were used to calculate area of impact, using computer aided drafting (CAD) software. Permanent impact areas adjacent to cut and fill locations include an additional 5 -foot width to allow for clearing and grubbing of vegetation at the base of all new infrastructure, and potential small changes in the project footprint. Impact calculations were obtained from the design team in square feet and rounded to the nearest hundredth of an acre. Total acres are determined from the summed square footage to most accurately determine total expected project impacts. Wetland Impacts The proposed project will impact 10 wetlands along the corridor, of which 4 will be a total loss. Approximately 7.15 acres of wetland will be permanently impacted as a result of this project, and an additional 0.80 acres will be temporarily impacted. Wetlands that will be impacted by the Project are listed and classified in Table 3. Graphical depictions of impacted wetland areas can be found in Attachment 1 — Impact Plan Sheets. 7 Table 3.

B) Permanent conversion impacts occur where wetlands are graded to create a stream channel. The wetland is permanently converted to stream. C) Long-term temporary impacts are those that can be restored by re -planting, but will take longer than one year to return to a pre -impact condition. Wetland 2.2R -B Wetland 2.2R -B will be completely filled as part of the project. This wetland occurs within the roadside ditch along the southbound on ramp to SR 167. The on ramp will be relocated to the west slightly to accommodate the support structure that will be constructed for the landing of the new flyover ramp from southbound I-405 to southbound SR 167. The flyover ramp is needed to provide direct access from southbound I-405 to southbound SR 167 in order to alleviate congestion and improve traffic flow during daytime traffic peaks. Wetland 2.318 Wetland 2.31R will be excavated as part of the project, lowering the elevation of the entire wetland unit. This wetland is located at the lowest point of the median between the northbound I- 405 on ramp and the northbound SR 167/Rainier Ave Ianes. There is a storm drain at the outlet of the wetland, making it an ideal location to incorporate additional storm drainage infrastructure for the new pavement being constructed as part of the project. A new stormwater detention pond will be constructed north of Wetland 2.31 R within the cloverleaf median of the northbound 1-405 exit ramp to northbound SR 167/Rainier Ave. The new detention pond will be connected to the existing storm drainage within wetland 2.31R by constructing a drainage ditch between the two points. Construction of the ditch will require excavation of the wetland. This excavation meets the criteria for a permanent wetland impact. 0 Wetland 2.6R A majority of Wetland 2.6R will be filled as a result of the project. This wetland is located in a depression which impounds storm water between Smithers Ave S to the east, Morris Ave S to the west, and S 14th Street to the north, at the bottom of Talbot Hill. There is a tall noise wall located between S 14th Street and northbound I-405, which reduces freeway traffic noise that affects local residents. The section of I-405 north of S 14`h Street is being shifted to the south as part of the project. This is required in order to accommodate the takeoff point of the new flyover ramp along southbound I-405, and to keep the alignment forward compatible with the final build -out of the corridor, which will ultimately include one additional lane in each direction on I- 405. The shift of I-405 to the south also precipitates the need to relocate S 14th Street, some local residences, and the noise wall. Through outreach and collaboration with local residents as part of the National Environmental Policy Act {NEPA} process, it was determined that residents in the area preferred that a visual barrier remain between I-405 and their homes. In order to accommodate this request, the project proposes construct an earthen berm in an east/west alignment from Morris Ave S to near Talbot Road/SR 515. The location of the berm requires the placement of fill within Wetland 2.6R. A corrugated metal pipe will be placed under the berm to maintain drainage of the area toward Rolling Hills Creek to the north. The fill will impact over 90% of the.entire wetland area, so the remaining area is also considered a permanent impact, resulting in the total loss of Wetland 2.6R. Wetland 24.7R -A Wetland 24.7R -A will be partially fiIled and temporarily impacted by vegetation disturbance as part of the project. This wetland is the southern -most unit of the Panther Creek Wetland Complex which extends from the toe of the SR 167 embankment to the base of Talbot Hill to the east. Because the majority of the wetlands western boundary coincides with the toe of the SR 167 embankment, any project activity occurring off of the existing road prism will affect the wetland. Two maintenance pullouts will be constructed along northbound SR 167 at approximate mileposts 25.05 and 25.35 which will require fill in the wetland as well as vegetation disturbance for equipment access. The maintenance pullouts are needed to improve safety for WSDOT maintenance staff who routinely park vehicles on the roadside to conduct their work. Wetland vegetation in this area consists primarily of sitka willow which will be cleared and grubbed to accommodate fill for the expansion of the road prism. Where equipment access is needed, vegetation will be cleared, but not grubbed, to allow for natural re -growth of willows. It is expected to longer than one growing season for willows in the temporary impact areas to recover, which constitutes a "long term temporary" impact. Beginning approximately at milepost 25.54 on SR 167, fill will be placed along the eastern edge of SR 167, sloping at a 4:1 ratio from the new edge of pavement outward to the edge of the proposed media filter drain, then at a 2:1 ratio until the new slope meets the existing ground. A small portion of this fill will intercept the boundary of Wetland 24.7R -A, resulting in a permanent loss of wetland area and function. An additional area outside of the permanent fill placement will be utilized for temporary construction access, resulting in the clearing of sitka willows, and a long tern temporary impact to the wetland. DI Overall, the project will permanently impact 0.18 percent of the wetland, leaving over 99 percent of the area intact. Welland 24.7R -B Wetland 24.7R -B will be partially filled and temporarily impacted by the project. Beginning approximately at milepost 25.69 on the eastern edge of SR 167, and extending to milepost 25.89, the roadway will be widened to accommodate a new northbound lane. Along this portion of the project, fill will be placed along SR 167, sloping at a 4:1 ratio from the new edge of pavement outward to the edge of the proposed media filter drain, then at a 2:1 ratio until the new slope meets the existing ground. This new slope will intercept the wetland boundary along its entire length, resulting in permanent wetland impacts. Immediately east of this new slope, the woody vegetation will be cleared to allow for temporary construction access, resulting in a narrow strip of long term temporary wetland impacts. An upland berm is located at milepost 25.94 along SR 167 which has two 36 inch culverts running parallel to the highway, hydrologically connecting Wetland 24.7R -B to Wetland 24.7R - A. A new fish passable structure to convey Rolling Hills Creek under SR 167 will be installed just south of this berm structure. The berm will be partially relocated to the south in order to facilitate the flow of Rolling Hills Creek into the new fish passable crossing structure. The relocation of the berm will also result in permanent impacts to Wetland 24.7R -B, with long term temporary impacts occurring adjacent the new berm as a result of vegetation disturbance for equipment access to construct the berm. On the south side of the new berm section, a small area within Wetland 24.7R -B will be excavated at the outlet of a new culvert pipe which will replace the two 36 inch culverts that currently convey surface water flow through the berm. The hydrological connection between the two units of the Panther Creek Wetlands must be maintained preserve the overall wetland functions of Wetland 24.7R -B. Although the area subject to excavation will most likely continue to function as wetland in the longterm, the work meets definition of a permanent impact because it changes the wetland elevation. This will cause a small, but necessary, increase of permanent impacts to Wetland 24.7R -B. -Permanent Conversion Impacts In addition, a new stream channel will be excavated to connect Rolling Hills Creek to the new fish passable crossing structure in the northwest corner of Wetland 24.7R -B. The new channel will be excavated starting at the new crossing structure and extending northward, resulting in a permanent impact to Wetland 24.7R -B by converting it to stream channel. Overall, the project will permanently impact approximately 10.2 percent of the wetland, leaving nearly 90% of the area intact. Wetland 24.7R -C Wetland 24.7R -C is the northern most unit of the Panther Creek Wetland Complex and it includes Rolling Hills Creek within and adjacent to it at the north end, near the junction of SR 167 and 1-405. The vast majority of project impacts occur within this wetland and stream complex. Continuing from the SR 167 widening to the south, fill will be placed east of the highway along the western edge of Wetland 24.7R -C. The roadway will be widened, sloping at a 10 4:1 ratio from the new edge of pavement outward to the edge of the proposed media filter drain, then at a 2:1 ratio until the new slope meets the existing ground in the wetland. There is an existing gas pipeline buried under Wetland 24.7R -C that runs parallel to SR 167 and I-405 throughout the project area. The pipeline will be relocated in order to remain uncovered by highway pavement and outside of WSDOT right of way. The project proposes to move the pipeline approximately 100 feet to the east throughout its extent in Wetland 24.7R -C. The proposed new pipeline location ensures that the new layout is forward compatible with future widening projects on SR 167 and I-405 so that the pipeline will not need to be relocated again. -Permanent Conversion Impacts A majority of the new channel for Rolling Hills Creek will be constructed through this wetland unit. The excavation will be a continuation of the work in Wetland 24.7R -B just to the south, resulting in a permanent conversion from wetland to stream in this location. -Indirect Permanent Impacts The excavation of the channel and connection to the new fish passable structure is expected to result in hydrological changes to a Iarge portion of the wetland unit. The site is expected to drain more readily through the new culvert which will result in shorter periods of inundation across the wetland throughout the year. Over time, the upper portions of the wetland (above 16' elevation) may no longer receive sufficient hydrology to support wetland vegetation. This potential outcome is proposed as an indirect permanent loss of 2.76 acres of Wetland 24.7R -C. Wetland 25. OL This wetland is being impacted due to roadway widening to accommodate the additional southbound lane, There is a retaining wall running the length of this wetland unit where it abuts SR 167. The retaining wall will be reconstructed to the west, to the extent necessary for roadway widening Wetland 25.7L This wetland is being impacted due to roadway widening to accommodate the additional southbound Iane, and to install an open -top stormwater vault. This location is most appropriate hydraulically to provide maximum detention of stormwater generated by the additional pavement. Wetland 25.8L This wetland is being impacted due to the relocation of East Valley Road. East Valley road must be relocated in this location in order to accommodate the widening of SR 167. Wetland 25.9L This wetland is being impacted due to the relocation of East Valley Road. East Valley road must be relocated in this location in order to accommodate the widening of SR 167. 11 Impacted Wetland Functions Wetlands in the project area were classified under HGM, and the functions evaluated using the Washington State Wetland Rating System for Western Washington (Hruby 2006) and WSDOT Wetland Functions Characterization Tool for Linear Projects manual (WSDOT 2000). The impact area was examined to determine approximate wetland functions to be impacted. All affected wetland acreage provides moderate to low water quality, hydrologic, and habitat functions): Water Quality - The wetlands impacted by the Project generally perform water quality functions at a moderate to high level. Herbaceous vegetation tends to be dense in the impacted wetlands, and the opportunity to remove sediments and toxicants is abundant due to the highly developed nature of adjacent lands. Seasonal ponding occurs in all of the impacted wetlands, and dense vegetative cover provides shade and reduces water temperature. Most of the impacted wetlands are small, and have restricted outlets such as culverts or steel grates. The portions of each wetland that provide seasonal water storage tend to be large, in proportion to the overall wetland area. Wetlands 2.2R -B, 2.31R, and 2.6R will be impacted completely, losing all water quality functions. The remaining impacted wetland areas will not see a significant loss in this function because large portions of these wetlands will remain intact. Wetlands 24.7R -A, -B, and -C, will be restored with dense native vegetation, but seasonal ponding will be reduced due to the connection of the wetland to a new fish passable structure. Hydrologic - Wetlands 2.2R -B, 2.31 R, 25.9L, and 2.6R are limited in their ability to provide hydrologic function due to small storage capacity compared to the contributing drainage basin. Wetlands 24.7R -A, -B, and -C, 25.OL, and 25.8L provide water storage due to their ability to store high volumes of water during storm events. The overall area and depth of seasonal ponding for these wetlands is relatively large when compared to the size of the total wetland area and the drainage basin. Approximately 2.76 acres of wetland 24.7R -C will be significantly altered in terms of hydrologic function, due to the grading of a stream channel through it and the construction of a fish passable structure under SR 167 along the western edge of the wetland. Habitat - The wetlands to be impacted by the Project generally perform habitat functions at low to moderate levels. Many of the impacted wetlands contain non-native invasive vegetation and adjacent habitats are fragmented by heavy development. Rolling Hills Creek runs through a portion of Wetland 24.7R -C, giving it some opportunity to provide off -channel fish habitat during high flows. This function will remain intact, and may improve in the future if downstream fish passage barriers are removed, allowing salmonids and other fish access to the area. Currently, there are no documented salmonids in Rolling Hills Creek or its adjacent wetlands. All of the impacted wetlands receive minimally treated or untreated stormwater runoff from adjacent impervious surfaces, including the adjacent I-405 roadway. Most of the wetlands are located adjacent to the roadway and contain little vegetated buffer. The presence of invasive plant species in the impacted wetlands is generally high, including reed canarygrass, and Himalayan blackberry, and special habitat features such as woody debris, snags, or brush piles are limited. 12 Stream Impacts The project will have permanent impacts to one stream (Rolling Hills Creek), and may temporarily impact another (East Fork Panther Creek). Rolling Hills Creek will be permanently filled for highway widening in the southeast corner of the I-405/SR 167 interchange. A graphical depiction of the stream impact area is included in the attached Impact Plan Sheets. Table 4 provides a summary of stream impacts. Table 4. Stream Impacts Summary Notes: A) Stream types are defined by the Washington State Department of Natural Resources. Type F streams are those that are known to be used by fish, or meet the physical criteria to be potentially used by fish. Fish streams may or may not have flowing water all year; they may be perennial or seasonal. Buffer Impacts The project will have unavoidable impacts to buffers. The project will permanently impact portions of 5 wetland buffers totaling 0.82 acre (Table 5). Temporary buffer impacts will total 0.13 acre and will occur to portions of 5 wetlands. Buffers in the project area were defined according to the City of Renton Critical Area Regulations. Where wetland and stream buffers overlapped, priority was given to wetland buffers. The only portion of the project where stream buffers were not overlapped by wetland buffers is along the day -lighted section of Rolling Hills Creek running east to west along the southbound I-405 lanes. Because no impacts are expected in that location, all impacted buffers reported for the project are defined as wetland buffers. For impact analysis, buffers only include vegetated areas outside of the developed road prism. Existing structures such as managed road embankments, buildings, and paved or impervious surfaces do not provide functions for adjacent aquatic resources, and were excluded from buffers. Most of the wetland buffers in the project area are limited in width and function due to adjacent structures and paved surfaces. Table 5.

The project proposes to mitigate impacts through on-site restoration and the purchase of mitigation bank credits from the Springbrook Creek Wetland and Habitat Mitigation Bank (Bank). On-site restoration will compensate for temporary impacts to all sensitive areas, and some permanent impact due to replacement of fish passage barrier in the project area. Bank credits will be utilized as compensation for permanent wetland and buffer impacts. These activities are proposed in order to meet regulatory requirements for sensitive area impacts as described below. Regulatory Requirements - As identified in the Governor's Executive Order 89-10 (Protection of Wetlands: "No Net Loss" (Order) and WSDOT Directive 31-12 (Protection of Wetlands Action Plan), WSDOT is required to create or restore wetland area and function at a minimum 1: l mitigation ratio. In order to meet temporal loss of wetland functions from long-term temporary impacts, Ecology recommends a mitigation ratio of one-quarter of the typical ratio for permanent impacts in addition to restoring the temporary impact on-site. Mitigation for impacts to wetland buffers is regulated by the City of Renton Critical Area Regulations. Impact Rehabilitation - Temporary Wetland and Buffer Impact Restoration - Temporary wetland and buffer impacts will be restored on-site at the impact locations along the project corridor after construction. These areas will be restored to improved conditions with native shrub and/or forested vegetation communities. Final plans and construction details for this restoration work will be produced by the Design -Builder prior to construction. Compensatory Mitigation - Stream Impact Mitigation - Temporary impacts to East Fork Panther Creek are not likely to result in any significant vegetation disturbance. If vegetation is disturbed, native woody species will be installed a minimum of 5 feet apart. The Design -Builder will work with WSDOT to develop a final restoration plan for temporary stream impacts prior to construction. Permanent impacts from fill in Rolling Hills Creek will be mitigated by relocating and enhancing the main channel to the east, and extending it approximately 1,400 feet to the south where it will cross SR 167 through a new, fully fish passable structure. For the purposes of this memo and 14 additional project documentation, the site will be referred to as the Rolling Hills Creek Restoration Site. The proposed location for the Rolling Hills Creek Restoration Site is just east of the existing channel, in a large Category 11 wetland complex. The wetlands are confined by SR 167 to the west and a very steep hill to the east. The current Rolling Hills Creek channel in this area runs partially through the wetland, and then behind a berm separating the creek and wetland before entering a culvert under SR 167 at (approximate) milepost 26.08 (Figure 2). Figure 2. Rolling Hills Creek Restoration Site Location A conceptual plan for the Rolling Hills Creek alignment and a planting plan for its restoration are provided in Attachment 3. However, the final configuration of the channel will be determined by the Design -Builder, and approved by WSDOT prior to construction. The basic requirements for the channel re -alignment and associated restoration, which will guide the Design -Builder, are as follows: ■ Create a new Rolling Hills Creek channel that flows from the outlet of Culvert 42 at the northbound (NB) SR 167 on-ramp to NB 1-405] to the inlet of a newly constructed fully fish passable structure at (approximately) milepost 25.932 along NB SR 167. o The new channel must be set back a minimum of 25 feet from the relocates} Olympic Pipeline for monitoring and maintenance. 15 o Size the new channel appropriately to match the form and function of the existing channel. The new channel must carry the modeled 2 -year flow and should be expected to overtop during heavier storm events. ■ Incorporate Large Woody Debris (LWD) into the channel according to WDFW Stream Habitat Restoration Guidelines (WDFW 2012). ■ Install native vegetation appropriate for the expected site conditions, including trees, on both sides of the channel to provide shading. Woody shrubs and trees species must be planted a minimum 25 -feet from the Olympic Pipeline. Rolling Hills Creek Restoration Site - Goals, Objectives, and Performance Standards The goals and performance standards in this memo are to assure the development of a functional, self-sustaining stream restoration site. WSDOT will achieve project mitigation goals and objectives by meeting the stated performance standards within 7 years of construction. Goal — The overall goal of the proposed mitigation is to replace stream and riparian functions lost by the permanent impacts to Rolling Hills Creek, while providing a fully fish passable structure under SR 167. Objectives — The specific activities to achieve this goal are: ■ Re -locate and restore a minimum of 520 feet of Rolling Hills Creek. ■ Replace the existing 10 -foot wide and 520 -foot long segment of Rolling Hills Creek with an 11 -foot wide and 1400 -foot long (channel length is approximate, based on conceptual design) channel segment that will flow to a fully fish passable stream simulation crossing structure. Enhance riparian function along the new channel by establishing native herbaceous and woody plants. The Rolling Hills Creek Restoration Site will include riparian vegetation on both sides of the new channel where feasible. The final planting plan will maximize shading and riparian habitat to the greatest extent possible, given the constraints of the site. The final planting plan will be approved by WSDOT prior to construction. Native Woody Vegetation Performance Standards Years 1 and 3 — Native woody species (planted and volunteer) will achieve an average density of at least 4 plants per 100 square feet in the forested buffer areas. 16 ■ Year S - Cover of native woody species (planted and volunteer) will be at least 30% cover in the forested buffer areas. ■ Year 7 - Cover of native woody species (planted and volunteer) will be at least 40% cover in the forested buffer areas. Native Herbaceous Vegetation Performance Standards ■ Years 1 and 3 – Native herbaceous species (planted and volunteer) will achieve an average density of at least 4 plants per 100 square feet in the streambank planting and restoration seeding areas. ■ Year 5 - Cover of native herbaceous species (planted and volunteer) will be at least 40% cover in the streambank planting and restoration seeding areas. ■ Year 7 - Cover of native herbaceous species (planted and volunteer) will be at least 60% cover in the streambank planting and restoration seeding areas. Noxious and Invasive Weeds Performance Standards Eradication of all occurrences of Class A weeds is required by state law. The Washington State Noxious Weed Control Board or a county weed board may designate certain Class B weeds for control or eradication in regions where they are not yet widespread. Years 1-7—Invasive weedy plant species and Washington State and King County listed noxious weeds will be managed across the site in accordance with the following standards: Noxious Weeds - Washington State -listed or King County -listed Class A weeds observed in any area of the mitigation site must be eradicated. All occurrences shall be immediately reported to the site manager and an eradication program will be initiated within 30 days of the report. King County Regulated Class B and C weeds must be controlled to prevent all seed production and dispersal of all propagative parts capable of forming new plants. King County's list requiring control includes purple loosestrife (Lythrum salicaria), musk thistle (Carduus nutans), and Scotch thistle (Onopordum acanthium). Invasive knotweeds, including Polygonum cuspidatum, P. polystachyum, and P. sachalinense must also be controlled so they do not spread. Invasive weeds - No more than 30% cover by nonnative, invasive plants except: 0 20% maximum cover across the entire mitigation site for nonnative blackberry species. In addition, invasive species listed in Table S and any other species that competes with desirable vegetation will be controlled across the mitigation site until performance standards for native vegetation have been achieved. Table 6. Non -Native Invasive Species 17 C tisus sca arius Scot's broom Phalaris arundinacea Reed canarygrass Cirsium arvense Canada thistle Cirsium vul are Bull thistle Dolling Hills Creek Restoration Site — Monitoring Plan - The site will be monitored for a minimum of five years. Monitoring procedures will be performed for up to five years after initial acceptance of the mitigation construction. The site should be evaluated informally the summer following plant installation to evaluate initial survival rates and to document the presence of any non-native invasive species. Report submittals will occur in years 1, 3, and 5, with a final closeout report in year 7. Monitoring reports will be submitted to the City of Renton, WDFW, Ecology, and the USACE, annually for review and comment. WSDOT staff will monitor the site to determine if the performance measures and success standards have been met. Successful mitigation will be measured by attainment of the success standards described in this memo. If the performance measures or success standards have not been met, adaptive management strategies will be deployed to achieve the final success standards. Monitoring will cease as soon as all success standards have been attained. Effective plant installation during construction will be critical to the long-term success of the site and ensuring that success standards can be met. The contractor will be responsible for maintenance and survival for one year following initial planting. Survival will be assessed by WSDOT after initial planting, and the landscape contractor will replace all plantings that do not survive within the first year. The Design -Builder will also reseed any areas of bare soil within the first year. Plant substitutions, if necessary, will be agreed upon by the project biologist and landscape architect. Plants damaged or destroyed by vandalism or wildlife grazing (by waterfowl, rodents, or ungulates) will also require replacement. The landscape contractor will have the option of protecting the plants from vandalism or herbivore grazing but must replace any dead plants during the guarantee period. Contingency Plan — Rolling Hills Creek Restoration Site - As necessary, contingency measures (i.e., adaptive management options) will be implemented to meet performance measures and success standards. Several factors, both man-made and natural, could have a detrimental effect on the success of the mitigation. No contingency plan can foresee all problems and their solutions. In all cases, if a more effective remedy is identified, it will be considered. Problems related to vegetation include plant mortality, lack of vigor and vitality, and poor growth resulting in low plant cover. These problems can be the result of insufficient maintenance, particularly watering in the first few growing seasons, animal browse, competition 18 from invasive species, flooding, disease, incorrect plant selection, altered site conditions, and vandalism. Contingencies for plant mortality and poor plant cover include: ■ Plant replacement — Additional planting may be required to meet plant survival and plant cover requirements. Plant species will be evaluated in relation to site conditions to determine plant substitutions. ■ Weed control — Control of non-native invasive species may be required to meet survival and plant cover requirements. Weed control methods could include mechanical or hand control, mulching, or herbicide application. ■ Herbivore control — If plant survival or vegetation cover standards are not met because of animal browse, the wildlife responsible will be identified and the appropriate control measure will be employed. This could include plant protection, fence installation, or the use of repellents. ■ Vandalism — To prevent vegetation disturbance from vandalism, fence installation and sensitive area signage may be installed. Long-term Site Management — Rolling Hills Creek Restoration Site - The goal of the proposed stream impact mitigation is to create a functional, self-sustaining system that requires little or no maintenance. WSDOT will regularly maintain the site for a minimum of 3 years, or until all success standards are met and the site is closed with the approval of regulatory agencies. After the site is closed out, maintenance will be conducted on an as -needed basis and can include noxious weed control, plant replacement, weeding, mulching, fertilizing, supplemental watering, correcting erosion or sedimentation problems, and trash collection. The first year of plant establishment includes supplemental watering and care of all replacement plants installed during the first year. Compensatory Mitigation — Permanent Wetland and Buffer Impact Mitigation - To fully compensate for unavoidable permanent impacts to wetlands and buffers from the Project, WSDOT proposes to debit wetland mitigation credits from the Springbrook Creek Wetland and Habitat Mitigation Bank. Compensatory mitigation for all permanent wetland and buffer impacts will be accomplished by replacing wetland functions and acreage lost by debiting credits provided at a regulatory approved mitigation bank. Effective June 9, 2008, the USACE (33 Code of Federal Regulations [CFR] Parts 325 and 332), and Environmental Protection Agency (40 CFR Part 230) issued a final rule that establishes a preference for the use of available mitigation bank credits. Since a mitigation bank must have an approved mitigation plan and other assurances in place before any of its credits can be used to offset permitted impacts, some of the risks and uncertainties associated with compensatory mitigation are reduced. Springbrook Bank is a large habitat restoration and wetland re-establishment site located in the city of Renton, WA, Green-Duwamish WRIA 9. The Bank was created to provide compensation for unavoidable impacts to wetlands and other aquatic resources caused by highway construction projects. The implementation of the Bank is intended to increase wetland area and encourage 19 improved hydrologic, water quality, and habitat functions, while facilitating environmental education opportunities along Springbrook Creek in a highly urbanized area. The objectives of the Bank are to re-establish 17.79 acres of wetland, rehabilitate 52.14 acres of wetland, enhance 32.54 acres of wetland, and enhance 7.80 acres of upland and 6.55 acres of riparian upland adjacent to Springbrook Creek for a total of 116.82 acres; the remaining acreage consists of non-credit generating buffers. The inclusion of non-credit generating buffers increases the value of the wetland credits because the presence of the wide buffer areas ensures the protection of wetland functions developed on the interior portion of the site. Purchase of wetland credits includes protection of that credit area by associated buffers, which compensates for any buffer impacts that occur on projects associated with direct wetland impacts. The restoration and enhancement activities have re -connected floodplain wetlands with Springbrook Creek, re-established wetlands, and likely improved water quality, hydrologic, floodplain, habitat, and riparian functions. Additional information on the Bank is available in the Springbrook Creek Wetland and Habitat Mitigation Bank Instrument (MBI) (WSDOT 2006). Proposed Mitigation Credits Credits are the "currency"of the mitigation bank. The value of each credit is equal to its net ecological benefit. For the Springbrook Bank, the value of one credit was developed to be equal in value to 1 acre of Category II wetland. Specifically, the Bank requires the use of 1.0 credit per acre (1:1 ratio) of permanent Category Il wetland impacts, 0.85 credits per acre (0.85:1 ratio) of category 11I, and 0.70 acre for category IV. Credits for Category I wetland impacts do not have a standard ratio, and are issued on a case-by-case basis. There are no Category I wetlands within the project footprint, so none will be impacted. For this project, the number of credits proposed to offset each impact type may deviate from the Bank requirements due to the nature of the impacts. The standard ratio is applied when an impact is occurring due to the installation of roadway elements and the Olympic Pipeline petroleum pipeline. A modified ratio is applied for impacts occurring as a result of conversion from wetlands to stream or impacts that will result in a temporal (as opposed to permanent) loss of wetland functions due to long-term vegetation disturbance. Table 7 summarizes the proposed mitigation credits. The various ratios are based on recommendations from permitting agencies through early project coordination. 20 r CV n O kn m o w o0 o N �t C, 00 n 00 a~ ��t Lr) O DO N ON ct oo Ln Wn � = kn O N -- O O O N O 00 M O O= O O �c O to M -- 4 0 O O O O O O O M O C O 0 O O a +- C O O Q C C p C7 O 0 0 .--� '--� t+i 1p O Q O +--� O O O O O O -- N N ON N O N O O O C �w Ci kn W) Wn V-) F� 0 Q 4 CLl Ga A0 U U U U U xrzcx�rx�a�r�rx�r.� a.aaaaaa n n n n n n n n R: .-• o Q n n o0 00 a, CY d �t N rti �O Wi Ln vi vi vi vi N N N N N Ifq N N N N N N N N N N N N N N N r CV Credit Acquisition and Timiw Credits have been released from the Springbrook Bank according to Table 4-3 of the MBI, provided that the Springbrook Bank demonstrates success in meeting performance standards. The credit release process, including performance standard milestones, is outlined in Chapter 4 of the MBI. An accounting ledger has been attached to this memo to summarize the credits and debits applied to the Bank since the initial credit release in 2006. According to the ledger, as of April 2014, the bank has over 12 credits available for use by WSDOT (See attachment 2 — Springbrook Credit Ledger. This project, as proposed, will utilize approximately 5 of the available credits. Should the Design -Builder modify the project in a manner that results in a different required credit amount, WSDQT will provide updated impact and mitigation information prior to construction. If impacts are decreased as design is advanced and finalized by the design builder, updated information may be provided to regulatory agencies to serve as the basis for a request to reduce Springbrook Bank credit use. If regulatory agencies approve a request to decrease the number of Springbrook Bank credits used to compensate for project impacts, an adjustment to the ledger total will be made to reflect that approval. Criteria for Using Bank Credits For a project to use credits from the Springbrook Bank, the wetlands or aquatic resources impacted by the project must be located within the service area and meet the Springbrook Bank's purpose, goal, and objectives. The Project is located entirely within the service area of the Springbrook Bank. In addition, the wetland mitigation needs of the Project correspond with the purpose, goals, and objectives of the Springbrook Bank. Therefore, the Project meets all required criteria for use of Springbrook Bank credits for compensation of unavoidable permanent impacts to wetlands and buffers. 22 References City of Renton. 1992.

All elements of the project were subject to ESA consultation which concluded with a Biological Opinion issued jointly by the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFWS) on March 3rd, 2008 (NMFS Tracking No: 2007104219, USFWS Log No: 13410-2007-F-0416). Since that time, the 1-405, SR 515 Interchange Project, a portion of the overall project, was constructed between 2008 and 2011, as described in the original BA. An additional portion of the project, the 1-405, SR 167 High Occupancy Vehicle Direct Connect Ramp Project, was included in the consultation, but never funded for construction. As of 2015 that project, now referred to as the Direct Connector Project, is yet unfunded for construction, but NEPA has been re-evaluated and a permit application has been prepared for all federal, state, and local permits needed for construction. The re-evaluation process revealed that there are new listings under ESA that were not addressed in the original consultation. This Biological Assessment Update provides the most current Direct Connector Project information to determine the effect on yellow -billed cuckoo (Coccyzus americanus) and the Oregon spotted frog (Rana pretiosa). The BA Update will also address potential project effects to proposed Puget Sound Steelhead Critical Habitat, and provide a provisional effect determination, as critical habitat is expected to be designated in 2015. This BA Update does not address the streaked horned lark (Eremophila alpestrrs strrgata) or the Taylor's checkerspot butterfly (Euphydryas editha taylon), both listed in 2013. They are not documented or known to occur within the project action area, and suitable habitat is not present. The Effect Determinations from the Direct Connector Project on listed species and proposed critical habitat are as follows: 1-405/SR 167 Direct Connector Project Page I Table 1.

In addition to addressing newly listed species and habitats, current project information is being provided on the 1405, SR 167 High Occupancy Vehicle Direct Connect Ramp Project (Direct Connector Project), which was addressed in the original BA, but has not been funded for construction. The project has been re-evaluated for NEPA compliance which facilitated the need for an update to ESA documentation. Background and Consultation History The original BA was submitted on June 26th, 2007, and requested consultation for the following species/critical habitats and effect determinations: Species • Chinook salmon (Oncorhynchus tshawytscha) — May affect, likely to adversely affect • Steelhead trout (Oncorhynchus mykiss) — May affect, likely to adversely affect • Bull trout (Salvelinus confluentus) — May affect, likely to adversely affect Critical Habitats • Puget Sound ESU Chinook salmon — May affect, likely to adversely affect Coastal -Puget Sound ESU Bull trout — May affect, likely to adversely affect A Biological Opinion (BiOp) (USFWS Log No: 12410-2007-F-0416; NMFS Tracking No: 2007104219) was prepared jointly by the United States Department of Fish and Wildlife (USFWS), and National Marine Fisheries (NMFS) and submitted to WSDOT March 3`d, 2008. The BiOp indicated that both services concurred with the findings in the BA and an incidental take statement was provided. PROJECT DESCRIPTION Project Overview The Direct Connector Project will construct a portion of the project elements evaluated in the 1-405, Tukwila to Renton (1-5 to SR 169 — Phase 2) Environmental Assessment (March 2008) and Finding of No Significant Impact and Final Section 4(f) Evaluation (July 2008). This project will construct a new direct connector ramp for a high occupancy vehicle (HOV)/express toll lane (ETL) operation in each direction between SR 167 south leg high occupancy toll (HOT) lanes and 1-405 north leg HOV lanes. 1-405/SR 167 Direct Connector Project Page 1 The project will reconstruct sections of northbound 1-405 and northbound and southbound SR 167 to open up the medians to make room for the new direct connector ramps, construct a new HOV/ETL structure between SR 167 and 1- 405, widen/replace the 1-405 bridge over SR 515 (Bridge Number 405/016), construct new retaining walls, and relocate a noise barrier. The project will modify local roadways, including East Valley Road and S 14th Street, related to the interchange improvements and 1-405/SR167 widening. Other elements include: sign bridges; ITS and tolling equipment; storm water management facilities; Rolling Hills Creek channel realignment along the east side of SR 167 (MP 25.93 to 1-405); and installation of a fish passable water crossing structure for Rolling Hills Creek under SR 167 at the S 19th Street alignment (Figure 1). 1-405/SR 167 Direct Connector Project Page 2 Figure 1. Project Area Map The project is being completed using the Design -Build method of delivery. All descriptions of project actions and construction methods herein are based on a preliminary design concept which is subject to change as part of the final design process. Once selected, the Design -Builder will be responsible for producing a final design which WSDOT will review and approve before it is released for construction. 1-4051SR 167 Direct Connector Project Page 3 Stormwater The design of the Project stormwater improvements will generally utilize as much of existing drainage system as possible and provide treatment facilities that conform to accepted best management practices (BMPs) outlined in the current WSDOT Highway Runoff Manual (HRM). Final design will identify the work involved with highway runoff collection and conveyance, so the extent of reused and new systems is not known at this time. All sites selected for flow control facilities will be placed outside of the 100 -year floodplain. Final design may result in changes to the proposed stormwater treatment system, but no stage of the project, including the Direct Connector Project, will increase pollutant concentrations discharged to receiving waterbodies. Additionally, the construction of any new stormwater facilities will be timed such that the loading and concentration targets will be met for the Direct Connector Project as well as each future construction stage/project. The entire project addressed in the original BA was expected to increase the pollutant generating impervious surface (PCIS) area by 69.60 acres across three drainage basins. The Direct Connector Project occurs entirely within the Lower Green River and Springbrook Creek sub -basins and includes approximately 7.36 acres of the total new PCIS. The final design of the Direct Connector Project may result in changes to the number, type, size, and location of the proposed drainage facilities for the Project as long as the total BMP catchment area from the original consultation is achieved, along with the HRM requirements. The conceptual design for the Direct Connector Project includes the following stormwater components: • Existing stormwater collection and conveyance systems will be modified or additional systems will be constructed as required for the new roadway geometry and as required for stormwater management using equivalent catchment areas. Three new flow control facilities will be constructed. • WSDOT HRM compliant enhanced runoff treatment BMPs will be constructed or modified as required to meet environmental commitments made through NEPA and prior ESA consultation on the project. • One culvert under SR 167 will be replaced by a new fully fish passable structure. A section of Rolling Hills Creek will be extended for stream impact mitigation east of the widened section of SR 167_ Additional details on the stormwater design concept for the Direct Connector Project are provided in a hydraulic summary (Appendix A). 1-405/5R 167 Direct Connector Project Page 4 Fish Passage The Direct Connector Project will address one fish passage barrier on Rolling Hills Creek which crosses SR 167 at milepost (MP) 26.08 through a 3 foot by 4 foot box culvert. The existing culvert has been identified as a partial barrier to fish passage due to flow velocity. The conceptual design for a fully fish passable structure includes moving the crossing to the south, to MP 26.93 in order to daylight approximately 1,400 feet of stream rather than piping the stream for long distances under local roads and parking lots as in its current configuration. The new crossing structure will include a minimum channel width of 10 feet, and will be constructed first, allowing the stream to remain in its current location until construction is complete. A map of the stream relocation is provided in Figure 2_ 1-4o515R 167 Direct Connector Project Page 5 Figure 2. Fish Passage/Stream Relocation Map A new stream channel will be constructed from a culvert outlet along the northbound 1-405 on-ramp from SR 157, to the location where the new culvert will be constructed. The new channel will be stabilized with appropriately sized streambed sediment and gravel, and woody riparian planting and seeding. Once 1-4051SR 167 Direct Connector Project Page 6 the new channel is graded, planted, stabilized, and connected to the new fully fish passable structure, flow will be slowly introduced from the existing channel at the upstream end. After flow has been completely diverted to the new channel and crossing, the existing channel be filled for future widening and the remaining box culvert will be re -purposed as a stormwater facility. A restoration plan depicting a conceptual layout of the new stream channel and associated riparian vegetation is provided in Appendix B. Road Construction The Direct Connector Project will reconstruct portions of the 1-405 and SR 167 interchange to accommodate direct connector ramps and tolling infrastructure. This work will involve significant use of heavy equipment for earthwork, ground improvements (including pile driving), demolition, paving, and utility work. New flyover ramps will be supported by columns most likely installed in drilled shafts. A gas pipeline that runs parallel to SR 167 will be relocated approximately 200 feet to the east, to remain outside of the paved roadway through all remaining construction phases. Project Schedule The Direct Connector Project is not funded for construction. Should funding become available, the project will be completed utilizing the Design Build method of delivery, including final design and construction. The project would be constructed over 2-3 years. PROJECT VICINITY Streams and Stream Crossings There are two tributaries to Springbrook Creek that occur within the project vicinity. Rolling Hills Creek (Stream 09.SC-2.8) and East Fork Panther Creek (Stream 09.SC-25.7) are small urban streams that are heavily manipulated as a result of development in and around the City of Renton. Stream locations within the project area can be seen in Appendix C (Existing Conditions Sheets). From its headwaters southeast of the junction of 1-405 and Talbot Road, Rolling Hills Creek eventually flows northward between Talbot Road and S Puget Drive and into the project area approximately 200 feet south of 1-405. From this intersection, Rolling Hills Creek flows through a series of culverts under several commercial parking lots to where it ultimately daylights on the north side of 1-405 into an open channel between 1-405 and a parking lot associated with several local businesses including the Renton Cinema 8 and Triton Tower One. The creek then flows south in a culvert under the I-405/SR 167 Interchange, into an 1-405/SR 167 Direct Connector Project Page open channel that runs parallel to the NB SR 167 ramp to NB 1-405 for approximately 520 feet, under SR 167 and local streets, that eventually outlets to Springbrook Creek approximately 2,600 feet downstream. During high flow events, a portion of the flow from the section of Rolling Hills Creek between 1-405 and the Renton Cinema 8 parking lot is directed into an overflow culvert that also flows south under the 1-405/SR 167 Interchange, before daylighting in the Panther Creek Wetlands complex. This stream contains no ESA -listed fish but potentially has resident fish including sculpin, three-spined stickleback, cutthroat trout, as well as coho salmon. The East Fork of Panther Creek flows out of the Panther Creek Wetlands near SR 167 milepost 25.66 through a fully fish passable culvert (constructed by WSDOT in 2012) under SR 167. After flowing under SR 167 and East Valley Road, Panther Creek enters a large wetland complex west of East Valley Road containing forested vegetation. The creek continues through this wetland to where it flows into Springbrook Creek approximately 2,600 feet to the west. The east fork of Panther Creek has a limited stream buffer, mostly established by WSDOT as part of a previous project. This creek may be used by coho and Chinook salmon and cutthroat and steelhead trout as rearing habitat because of its association with Springbrook Creek. Wetlands There are 13 wetlands in the Direct Connector Project vicinity. The majority of them are small, palustrine scrub -shrub and emergent wetlands with limited habitat value or hydrologic function. A summary of wetlands in the vicinity is provided in Table 2. 1-4051SR 167 Direct Connector Project Page 8 Table 2.

The highest quality wetlands are Wetlands 24.7R -A, B, and C. This interconnected wetland complex is locally referred to as the Panther Creek Wetlands, although the complex includes portions of both Panther Creek and Rolling Hills Creek. The complex is divided into three units by berms with cross culverts running through them. This wetland complex is over sixty acres in size and includes forested zones, as well as some permanently ponded areas dominated by aquatic bed vegetation. Common herbaceous vegetation includes reed canarygrass (Phalaris arundinacea), cattails (Typha lafifolia) and soft rush (Juncus effuses). Shrub -dominated areas typically include Sitka willow (Salix sitchensis), redosier dogwood (Cornus stolonifera) and large stands of Himalayan blackberry (Rubus armeniacus). The remaining wetlands tend to be small and confined by adjacent impervious surfaces. Wetland 2.2R -B and 2.31 R are small depressions in roadside ditches. Wetland 2.31 is dominated by roadside grasses and receives SR 167 runoff. Wetland 2.2R -B is located in a deep ditch along the 1-405 off ramp to southbound SR 167 and contains a few shrubs, with a blackberry understory extending over the wetland from the steep embankments. Wetlands 25.OL, 25.7L, and 25.81L are linear features adjacent to SR 167 that provide drainage for adjacent paved surfaces.

Wetland 2.6R is located just south of 1-405 near Talbot Road. It is a small depressional wetland with steep sides dominated by Himalayan blackberry. The wetland includes a stand of shrubs on the west side and reed canarygrass at the lowest points. None of the wetland areas are known to be occupied by listed fish, amphibian, or other vertebrate species. Project Action Area This section describes the action area for the Project. The action area is defined as the geographic area potentially affected by the Project (Figure 3). The action area established in the original consultation has not changed. The furthest reaches of the action area can be affected by the high noise activities associated with pile driving for ground improvements. Construction noise will extend a maximum distance of one mile from the immediate work area before attenuating to background levels. The aquatic portion of the action area for the Direct Connector Project includes the Rolling Hills Creek crossing within the Panther Creek Wetland complex. There is potential for sediment mobilization associated with the fish passage work, but sediments will not extend more than 300 feet downstream because the stream is piped and mixes with significant amounts of drainage from the City of Renton. 1-405/SR 167 Direct Connector Project Pageta Mon t t� Figure 3.

This section of the BA Update will focus on the specific conditions of drainage basin surrounding the Direct Connector Project area. The bulk of the project work occurs in the Springbrook Creek sub -basin of Water Resource Inventory Area (WRIA) 9. The Springbrook Creek subbasin enters the mainstem Green River via the Black River at RM 11.0. With an estimated mainstem stream length of 12.0 miles, and approximately 19.1 miles of tributary streams and 3.8 miles of drainage ditches, it is the largest subbasin in the lower Green River Basin (Williams et al. 1975). The Springbrook Creek subbasin drains an area of about 15,763 acres. The basin is comprised of two distinct physical settings. In the eastern half of the subbasin, rolling hills rise to elevations of about 525 feet above the valley floor. In this area, the origins of stream courses are often not well defined. Slopes in the subbasin .range from near 0 to 70 percent. One significant lake is present (Panther Lake) along with several smaller ponds and wetlands. Creeks originating from these upland sources drop abruptly through sharply defined steep canyons to the valley floor where stream gradients flatten quickly. Typically, these canyons are short, with high gradients and generally are not accessible to anadromous salmonids (Kerwin 2001). In 1958, an earthen dam was constructed on the Black River approximately 1,000 feet upstream of the confluence with the Green River. This blocked passage of anadromous fish into Springbrook Creek. Besides impeding salmonid migration into the Springbrook Creek system, this dam blocked flows from the Green River from backwatering into the remnant Black River, which could have provided some refuge habitat for salmonids during high flows. In 1972, the U.S. Soil Conservation Service replaced the dam with the Black River Pumping Station (BRPS), which currently is operated by King County. Although it is equipped with upstream and downstream fish passage facilities, the BRPS can act as a barrier to migration of juvenile and adult salmonids due to inadequate screening, fish weir design, and operation schedule (Kerwin 2001). There are several barriers along Springbrook Creek and associated tributaries. Between the SR 167 crossing and Talbot Road, the creek flows through a private trout farm that presents a barrier for migrating anadromous salmonids under most stream flow conditions. Several sections of Springbrook Creek are so choked with invasive reed canarygrass and vegetation that they serve as partial barriers. If the bypass reach is dewatered, then it would also serve as a barrier to downstream migration. Upstream of the trout farm, Springbrook Creek flows through a 30 -foot -long 1-405/SR 167 Direct Connector Project Page 12 culvert and standpipe that is sloped at approximately 100 percent in the vicinity of Talbot Road. On the South Fork of Springbrook Creek, there is a concrete pad and notched weir that likely is a barrier to upstream and downstream migrating anadromous and resident fish. Water quality may serve to act as a barrier to anadromous migrating fish in the lower reaches of Mill and Springbrook Creeks (Kerwin 2001). In the immediate vicinity of 1-405, Springbrook Creek is largely contained within concrete walls for flood control purposes. Springbrook Creek flows under 1-405 under two bridges that were constructed as part of the Renton Nickel Improvement Project. Downstream of where Springbrook Creek flows under SW Grady Way, Springbrook Creek is no longer contained in a concrete channel, but is still confined within an incised riprapped channel. Riparian vegetation surrounding Springbrook Creek is a mixture of alder and willow species, Himalayan blackberry, and sedges (Carex spp.). Conifers are almost non-existent and, in those areas where shade is absent, reed canarygrass is abundant. Riparian habitat within this creek does not meet the NMFS criteria for properly functioning habitat and is a limiting factor to natural salmonid production (Kerwin 2001). Vegetation in the vicinity of Rolling Hills Creek (a tributary to Springbrook Creek) consists of wetland herbaceous plants, reed canarygrass, willows, cottonwoods, and some Oregon ash (Fraxinus latifolia). Springbrook Creek is listed on Ecology's 303(4) list for exceedances of fecal coliform and dissolved oxygen (DO).

The Service will make a final determination on Oregon spotted frog critical habitat sometime in the future. The Oregon spotted frog is a medium sized frog that ranges from about 1.7 to 4.1 inches (44 to 105 millimeters) in body length (Federal Register 2014). It is named for the characteristic black spots covering the head, back, sides, and legs. The dark spots have ragged edges and light centers, usually associated with a tubercle or raised area of skin. Adults range from brown to reddish brown but tend to become redder with age. The Oregon spotted frog has a weak call consisting of a rapid series of six to nine low clucking notes described as sounding like a distant woodpecker's tapping. Oregon spotted frogs burrow in muddy, silty, substrate; clumps of emergent vegetation, woody accumulations within a creek, and holes in creek banks when inactive during periods of prolonged or severe cold. This species remains active during the winter in order to select microhabitats that can support aerobic metabolism and allow it to evade predators. As with other ranid frogs, most daily movements are relatively short (10s of feet) and seasonal movement may be 100s of feet. These frogs occasionally will move a few miles, and it is presumed that Oregon spotted frog habitats are connected for purposes of genetic exchange when occupied/suitable habitats fall within a maximum movement distance of 3.1 miles. This species typically begins to breed at three years of age. Breeding occurs in February or March at lower elevations and in late May or early ,tune at higher elevations. Females may deposit egg masses at the same location in successive years in shallow, often temporary, pools no more than six inches deep. Eggs usually hatch within three weeks after oviposition. Tadpoles are grazers, having rough tooth rows for scraping plant surfaces and ingesting plant tissue and bacteria. They also consume algae, detritus, and probably carrion. Tadpoles then metamorphose into froglets during their first summer. Past -metamorphic Oregon spotted frogs feed on live animals, primarily insects. Eggs are extremely vulnerable to desiccation and freezing as a result of the species' laying habits. Although egg masses are. occasionally laid singly, the majority of egg masses are laid communally in groups of a few to several hundred in shallow, often temporary, pools of water; gradually receding shorelines; on benches of seasonal lakes and marshes; and in wet meadows. These sites are usually associated with the previous year's emergent vegetation, are generally no more than 14 inches deep, and most of these sites dry up later in the season. Shallow water is easily warmed by the sun, and warmth hastens egg development. Traditional egg laying habitat is limited, and 1-4051SR 167 Direct Connector Project PageJ5 adults may have limited flexibility to switch sites. Based on egg mass census data, the USFWS estimates the minimum Oregon spotted frog population in Washington was at least 7,368 breeding adults in 2012. The Oregon spotted frog inhabits emergent wetland habitats in forested landscapes, although it is not typically found under forest canopy. Historically, this species was also associated with lakes in the prairie landscape of the Puget lowlands. Oregon spotted frogs may no longer occur in as much as 76-90 percent of their historically documented range. This is the most aquatic native frog species in the Pacific Northwest, as all other species have a terrestrial life stage. It is almost always found. in or near a perennial body of water, such as a spring, pond, lake, sluggish stream, irrigation canal, or roadside ditch. Oregon spotted frogs can make use of a variety of pond types as long as there is sufficient vegetation and seasonal habitat available for breeding, summer feeding, and overwintering. Full solar exposure seems to be a significant factor in breeding habitat selection. Genetic studies indicate that gene flow among sites has been very low, even on small geographic scales. Due to Oregon spotted frogs' highly aquatic habits, connectivity between Oregon spotted frog sites depends on the connectivity of streams, rivers, and lakes. Gene flow (based on both microsatellite and mitochondrial analyses) is extremely low beyond 6 miles, and most Oregon spotted frog populations are separated by more than 6.2 miles. Threats to Oregon spotted frog include conversion of wetlands to other habitats, including natural succession of open wetland habitat to forest habitat, other associated hydrological changes (changes in flood regimes/ dam management and water drawdowns which desiccate habitat), non-native species (bullfrog/warm water fish predation, reed -canary grass invasion), the inadequacy of existing regulator mechanisms, and issues associated with small populations. Some federal and state programs promote tree planting for fish habitat restoration and curtailment of livestock grazing in riparian areas may have negative effects on Oregon spotted frog because they allow for the expansion of woody vegetation, degrading frog habitat. Although Oregon spotted frog is affected by several pathogens, including chytrid fungus (confirmed at all Washington and Oregon sites), diseases are not thought to significantly affect populations. Historical loss of wetlands has been extensive throughout the range of the species, and is the primary reason for the absence of the species from as much as 90 % of its former range. Much of the known frog habitat is dominated by reed canarygrass, which can negatively affect vegetation diversity, site hydrology, and vegetation cover; these frogs appear to actively avoid areas with high reed canarygrass density. Natural disturbance factors that helped maintain Oregon spotted frog habitat included meandering rivers and flooding of river floodplains, beaver dams, and summer fires. All served to remove woody vegetation and create openings in river floodplains and wetlands, and all factors currently operate at reduced rates. Many of the Oregon spotted frog breeding locations comprise less than 50 1-405/SR 167 Direct Connec4or Project Page16 adult frogs, are isolated from other breeding locations, and may already be stressed by other factors, such as drought or predation, and are more vulnerable to random, naturally occurring events. Six major Oregon spotted frog haplotypes have been identified based on mitochondrial genetic data; there is low genetic diversity within and high genetic differentiation among the six groups, and each of these groups has the signature of complete isolation, with two groups showing indications of recent genetic drift. Where Oregon spotted frog locations have small population sizes and are isolated, their vulnerability to extirpation from factors such as fluctuating water levels, disease, and predation increases. The minimum amount of habitat thought to be required to maintain an Oregon spotted frog population is about 10 acres. Smaller sites generally have a small number of frogs and are more vulnerable to extirpation. Species and Habitat Presence There are significant ponded areas within the Panther Creek Wetlands that could provide suitable habitat for Oregon spotted frog. However, the hydrology in this wetland complex is highly influenced by adjacent land use, and ponded areas are artificially large due to significant stormwater inputs. The hydrology and vegetation that would support Oregon spotted frogs are subject to rapid change, depending on present or future manipulations to drainage of surrounding developed areas. There are no recent records of Oregon Spotted Frog in King County. It is highly unlikely to be present in the project footprint due to the distance to known occupied habitats, and the lack of hydrologic connections between. The U.S. Fish and Wildlife Service has provided WSDOT with preliminary guidance on areas that may be occupied by Oregon spotted frog. These areas of influence include 19 5 1 and 6th field hydrologic unit codes (RUCs) in Washington State. The closest area of influence is Green River Kent (a historical site), more than 3 miles from the action area boundary. There is no proposed Oregon spotted frog critical habitat within the project action area. Yellow -Billed Cuckoo The USFWS listed the western distinct population segment (DPS) of the yellow - billed cuckoo (Coccyzus americanus) as threatened on October 3, 2014. The western states where cuckoos are found include Washington, Idaho, Montana, Oregon, California, Nevada, Wyoming, Utah, Colorado, Arizona, New Mexico, and Texas. No critical habitat was proposed in Washington State. The yellow -billed cuckoo ranges across all of North America, but eastern and western birds are separated by the Continental Divide (generally the crest of the Rocky Mountains based on watershed boundaries), the watershed divide between the Rio Grande and Pecos River, and the Chihuahuan Desert in 1-405/SR 167 Direct Connector Project Pager Mexico. Both eastern and western yellow -billed cuckoos are highly migratory, and the two populations may spend winters in overlapping regions in South America. There is an extremely low level of interchange (if any at all) between the two populations during the breeding season. Eastern and western birds differ by the several characteristics: 1) yellow -billed cuckoos in western North America arrive on the breeding grounds 4 to 8 weeks later than eastern yellow -billed cuckoos at similar latitude, 2) yellow -billed cuckoos in western North America are generally larger, with significantly longer wings, longer tails, and longer and deeper bills, 3) birds in western North America produce larger eggs (1.2 percent longer, 0.6 percent wider, and 3.2 percent heavier) with thicker eggshells, 4) Juvenile yellow -billed cuckoos in the east have yellow bills while juvenile yellow - billed cuckoos in the west have all -black bills. The yellow -billed cuckoo feeds primarily on larger invertebrates such as caterpillars, cicadas, katydids, and grasshoppers. In California and Arizona, yellow -billed cuckoos rarely begin nesting before mid-June. Nesting in western North America continues through August, and up to three broods can be raised in a season if the prey base is sufficient. Yellow -billed cuckoos build an open cup nest with a loose saucer-shaped stick construction. Both parents build the nest, incubate, and tend the young. Clutch size varies from two to five eggs depending on the available food supply. The incubation and nestling periods are short, with the eggs hatching in 11--12 days and young fledging in 5--7 days. Incubation begins when the first egg is laid and the young hatch asynchronously, with the oldest near fledging while the youngest has just hatched. Nesting habitat for the western yellow -billed cuckoo is in low to moderate elevation riparian hardwood woodlands that cover 50 acres or more within and to semiarid landscapes. In California, yellow -billed cuckoos are most likely to be found in patches of willow— cottonwood riparian habitat greater than 200 acres in size. Throughout the western DPS range, a large majority of nests are placed in willow trees, but alder (Alnus spp.), cottonwood, mesquite, walnut (Juglans spp.), box elder, sycamore, and tamarisk are also used. Other riparian hardwood trees that provide overstory canopy for cuckoo include sycamore (Platanus sp.), ash (Fraxinus sp.), and mesquite (Prosopis sp.). Dense riparian vegetation with an understory component is important for nesting cuckoos. Most nests are placed on well -foliaged horizontal branches at sites with dense canopy cover above the nest. Much of the habitat work on cuckoos has come from California and Arizona, so these are general guidelines. The yellow -billed cuckoo is extremely rare in Washington State (WDFW reports 12 records between 1950 and 2000 {four in western Washington, eight in eastern Washington), with three reports since 2000: near Lind (Adams Co.) in 2001, near Eureka (Walla Walla Co.) in June 2007, and from Little Pend Oreille National Wildlife Refuge (Stevens Co.) in June 2012. This equates to about 1 confirmed record every 4 years. There has not been confirmed breeding in Washington since 1934. 1-405/3R 167 Direct Connector Project Page 18 Species and Habitat Presence The Panther Creek Wetland complex and surrounding forested upland is one of the largest (nearly 80 acres) unbroken habitat patches in the urban parts of greater Seattle. The area provides foraging and dispersal habitat for many migratory birds, and presumably could be suitable for yellow -billed cuckoos. However, yellow -billed cuckoos tend to avoid noisy areas, making it unlikely they would pass through this site. The project is just a mile south of the Renton Municipal Airport and includes some of the most travelled highways in the state. Puget Sound Steelhead Critical Habitat Critical habitat has yet to be designated for steelhead trout, but was proposed for designation on January 14, 2013. Proposed critical habitat includes Springbrook Creek, but not Rolling Hills Creek. Proposed steelhead critical habitat is not within the action area for the Direct Connector Project. 1-406/SR 167 Direct Connector Project Page19 EFFECTS OF THE ACTION Direct Effects Direct effects associated with the project will primarily come from filling of wetlands and streams, and to a lesser extent, their associated buffers. There will be up to 7 acres of vegetation removal within the project footprint. A portion of that area occurs in a residential area south east of the 1-405/SR 167 interchange, where there is very little terrestrial habitat and no aquatic habitat. Permanent and aquatic resource impacts are as follows: Table 5. Wetland Impacts Summary Notes: A) Indirect Permanent impacts occur due to hydrology alterations in undisturbed areas as a result of culvert replacement. B) Permanent conversion impacts occur where wetlands are graded to create a stream channel. The wetland is permanently converted to stream.

The project will create approximately 7.36 acres of new PCIS. The vast majority of runoff from new PGIS will flow into media filter drain treatment facilities, then detention ponds, and eventually, Rolling Hills Creek. This will not affect ESA - listed species because none are present in Rolling Hills Creek. A small portion of new PGIS (approximately 1,000 ftz) will drain into existing media filter drains, before entering The Panther Creek Wetlands, and Panther Creek, which does contain some suitable habitat for Puget Sound steelhead. During active construction work, when grading, excavation, drilling, and pile driving are occurring, there will be visual and noise disturbances that can affect 1-405/SR 167 Direct Connector Project Page2l listed species. The support structure for new flyover ramps will be installed with drilled shafts. Pile driving for ground improvements along the widened section of SR 167 will not occur within the ordinary high water mark of Rolling Hills Creek, and it will not occur within 1,000 feet of Panther Creek. Work in and around Rolling Hills Creek will be limited to the workdays between June 161h to September 30th each construction year, to limit exposure to resident fish that may be present. Noise and visualdisturbances are not expected to affect ESA -listed fish, or the Oregon spotted frog due to the lack of species presence in the areas of disturbance. The yellow -billed cuckoo may be sensitive to the high noise generated by pile driving, concrete demolition, paving, and general construction activities, but they will typically avoid high noise areas. Construction noise generated by the Direct Connector Project will extend approximately 1 mile in all directions from the immediate work areas, but the project vicinity includes permanent noise generating fixtures including Renton Municipal Airport, and the 1-5 and 1-405 interchange, with the Sea -Tac International Airport located less than 4 miles away. The daily high ambient noise levels in the project vicinity make it unlikely that project -related noise will have a measurable effect on the yellow -billed cuckoo. Salmonid Species The project will have no direct effects to ESA -listed salmonids because they are not present in the action area. Work in and around Rolling Hills Creek does have the potential to impact non -listed resident fish which could include cutthroat trout, sculpin, coho, and three-spined stickleback. Vegetation and Wildlife The project includes up to 8 acres of vegetation disturbance. Most disturbed areas of will be restored after construction is complete, but there may be up to 0.28 acres cottonwood forest permanently removed, which would reduce perching opportunities for the yellow -billed cuckoo, if the species were using the site. This is a minimal loss of habitat, as the Panther Creek Wetland complex and adjacent uplands will still provide upwards of 20 acres of mixed conifer, big -leaf maple, cottonwood and Pacific willow forest adjacent to the shrubby and herbaceous wetland/stream areas. The conversion of wetland area to stream/riparian resulting from the re -alignment of Rolling Hills Creek will change a primarily wetland herbaceous community to a woody shrub/forest community with an open stream channel. This project effect on vegetation could result in a loss of suitable Oregon spotted frog habitat. However, Oregon spotted frog is not known or expected to occur in this area. Indirect Effects 1-40515R 167 Direct Connector Project Page22 Indirect effects associated with the project will result from the replacement of the Rolling Hills Creek culvert. A fully fish passable structure will permanently alter drainage of the Panther Creek Wetlands (Wetlands 24.7R -A, B, and C). It is not clear what long-term effects will result from the altered hydrology of the wetland, but it is possible the result will be the permanent loss of wetland hydrology and function for approximately 2.52 acres of the Panther Creek Wetlands. However, the presence of the new channel section and improved riparian function will improve fish habitat. The new channel section could provide rearing and foraging opportunities in the future if fish passage is restored downstream to Springbrook Creek. This will not affect listed fish species as no listed fish are currently present in this area. The altered wetland hydrology may also promote growth of cottonwoods in areas that are currently too wet, which may have a beneficial effect to migrating yellow -billed cuckoo due to the improved habitat. Interrelated and Interdependent Actions The original consultation identified one interrelated action, the construction of the Springbrook Wetland and Habitat Mitigation Bank (Springbrook Bank), which was completed in 2067. The Springbrook Bank was constructed to compensate for aquatic resource impacts in anticipation of future projects along the 1-405 and SR 167 corridors, including the Direct Connector Project. There are no additional interrelated or interdependent actions associated with the current project. 1-405/5R 167 Direct Connector Project Page23 MINIMIZATION MEASURES Avoidance and minimization measures are specific measures that will be incorporated into project construction to reduce potential effects to listed species or habitats. Vegetation and Wetlands • Sensitive areas and vegetation to remain will be delineated with high - visibility fencing to avoid impacts. • Clearing and grubbing will be limited to the greatest extent possible to retain existing vegetation and root structure. In areas where temporary access is needed, vegetation will not be grubbed, to allow more rapid recovery of native woody species cover. • Forested areas will be identified on plan sheets and protected to the greatest extent possible. Temporary access, staging, and stockpiling will be limited to upland sites that are already in a disturbed condition. Water Quality • A Temporary Erosion and Sediment Control (TESC) plan will be implemented to minimize water quality impacts during construction. • Silt curtains, sandbags, and straw wattles, and check dams will be utilized for instream work associated with fish passage. • A water quality monitoring plan will be implemented throughout in -water work to ensure the effectiveness of BMPs. Fish Exclusion • Fish exclusion will be conducted with the leadership of a qualified biologist with appropriate training. • Non-invasive methods will be employed to exclude fish from in -water work areas whenever possible. Seine nets and dip nets will be used as a first choice. Electrofishing will only be used as a last resort. Mitigation Mitigation credits will be utilized from the Springbrook Creek Wetland Mitigation Bank to compensate for approximately 6.8 acres of wetland impacts. The permanent impact of 0.06 acres (and 520 linear feet) of Rolling Hills Creek will be mitigated on-site with the re -aligning of the creek and subsequent restoration. The low -flow channel on the restoration site will be approximately 10 feet wide and 1400 feet long, resulting in a significant increase in open channel and riparian habitat along Rolling Hills Creek. 1-4051SR 167 Direct Connector Project Page24 EFFECT DETERMINATIONS Yellow -Billed Cuckoo The project may affect yellow -billed cuckoo because: ■ There is a large forested wetland complex (over 50 acres) including patches of cottonwood that will be impacted by the project, including the removal of up to 100 trees across an area of 0.28 acres. ■ The large tract of forested area including the cottonwood patches has the potential to provide dispersal or foraging habitat for migrating birds. ■ Elevated project noise may be generated when yellow -billed cuckoo are dispersing into northern habitats. If these birds were in the action area, they could be temporarily disturbed and displaced. The project is not likely to adversely affect yellow -billed cuckoo because: ■ Nesting yellow -billed cuckoo have not been documented in Washington or Oregon for many decades and are not expected within the action area; and ■ Yellow -billed cuckoo are sensitive to traffic noise (Goodwin and Shriver 2011), and dispersinglmigrating birds would likely avoid the elevated noise associated with the busy 1-405 corridor and the nearby Renton Municipal Airport. ■ The loss of 0.28 acres of hardwood forest in a heavily urbanized area would have insignificant effects on migrating cuckoos. Oregon Spatted Frog The project will have no effect on the Oregon spotted frog because: ■ The project is located in central King County where there are no currently known sites occupied by Oregon spotted frogs. ■ The potential presence of the species in the action area is discountable due to the distance to known historical or occupied sites and the limited mobility of the species. 1-405/5R 167 Direct Connector Project Page25 Puget Sound DPS Steelhead The original BA and Biap included an effect determination of May affect, likely to adversely affect the Puget Sound DPS steelhead. The Direct Connector Project will maintain that determination because there will be 1000 ff2 of new PCIS along Panther Creek. This will increase stormwater inputs into the creek, which may provide suitable habitat for steelhead. Puget Sound Steelhead Proposed Critical Habitat The project will not destroy or adversely modify proposed steelhead critical habitat. Should Puget Sound steelhead trout critical habitat be designated prior to completion of the project, a provisional effect determination for critical habitat is No Effect because: ■ The project does not include work in proposed steelhead critical habitat. The nearest proposed critical habitat is in Springbrook Creek approximately 2,600 feet downstream of the immediate project area. Potential turbid water generated during the Rolling Hills Creek culvert replacement and channel relocation will not affect proposed critical habitat downstream. 1-405/SR 167 Direct Connector Project Paye26 REFERENCES Washington State Department of Transportation (WSDOT). 2007.

Note that the final design will continue to develop these preliminary stormwater management concepts. The Design -Build Contract will specify performance standards that are based on the Washington State Department of Transportation (WSDOT) Highway Runoff Manual (HRM) requirements. This design is one solution that will meet that standard, but this information is subject to change during final design using equivalent mitigation measures. Project Watershed The project scope includes 1-405 Corridor improvements from MP 2.32 to MP 3.28, and SR 167 improvements from MP 24.80 to MP 26.26. The Project is located in the lower elevations of the Lower Green River sub -basin and Black River/Springbrook Creek sub -basin of state Water Resource Inventory Areas (WRIA) 9 — Green-Duwamish River Watershed. The upper portions of the Green- Duwamish River and Lake Washington watersheds have undergone relatively little development and most of the land cover is second -growth forest. The lower portions of these tributary basins, in contrast, have undergone extensive land use changes in the form of either agriculture or commercial, urban, and residential development. The.work is entirely within the City limits of Renton, Washington and falls within three tributaries of Springbrook Creek: Rolling Hills Creek, Thunder Hills Creek; and Panther Creek. In contrast to the biological assessment and ESA consultation, the Project flow control will be based on a predevelopment land cover definition following the current HRM. Predevelopment will be forested land cover condition except where the HRM allows an exemption for discharges to a 2 -year floodplain. In that case, the Project will verify that Minimum Requirement 7 (wetland hydroperiod criterion) is met. Runoff treatment design will follow the HRM and also meet the "no net increase" in average annual pollutant concentrations and loadings for Total Suspended Solids, Total and Dissolved Zinc, and Total and Dissolved Copper criteria established in the NOAA Fisheries Biological Opinion (BiOp) from the 1-445 Tukwila to Renton Improvement Project (1-5 to SR 169 — Phase 2) Environmental Assessment effort. 1-405/SR 167 Interchani )irect Connector Project JARPA Form Attachment 13 STORMWATER MANAGEMENT CONCEPT FOR 1-405/5R 167 INTERCHANGE - DIRECT CONNECTOR PROJECT Page 2 of 17 Project Drainage Basins The watershed is divided into two Threshold Discharge Areas (TDAs): Table 1: WRIA 9 - Green-Duwamish River Watershed, Lower Green River and Black River/Springbrook Creek Sub -Basins 11 t p i e"t.- 7 7- S2.2, S2.3, Rolling Hills and Thunder Hills Creek that SR -167 to approximately & S2.4 combine into the SW 19th Street tributary Renton City Hall and along drainage system to Springbrook Creek SR 167 from 1-405 to SE 19th Street S2.1 Panther Creek (SW 23rd Street channel) Along SR 167 from SE 19th tributary to Springbrook Creek Street to SE 41st Street Figure 1: Vicinity Map with TDA Locations (See Figure 2 for Streams) AWOL washinQton state Go- Department of Transportation 1-405/SR 167 Interchange - Di Connector Project ARPA Form Attachment 13 STORMWATER MANAGEMENT CONCEPT FOR 1-405/SR 167 INTERCHANGE - DIRECT CONNECTOR PROJECT Page 3 of 17 Proposal Overview The Project will increase the pollutant generating impervious surface area (PGIS) by 7.36 acres, approximately 19 percent over current conditions. The project will include the following stormwater facilities: • Existing stormwater collection and conveyance systems will be modified as required for the new roadway geometry and as required for stormwater management using equivalent catchment areas. • Three new flow control facilities will be constructed (see below for details). • WSDOT FIRM compliant enhanced runoff treatment BMPs will be constructed or modified as required to meet environmental commitments made in the Environmental Assessment and ESA Consultation process. • One culvert under the SR 167 corridor (Mile Post 26.07) will be replaced by a new fish passable structure (Mile Post 25.93). • A section of the Lower Rolling Hills Creek will be extended. This work will also provide stream restoration along the east side of SR 167 between SW 19th Street and the northbound SR 167 to northbound 1-405 ramp. See Attachment 13B for an illustration of the preliminary stormwater facilities. Flow Control Infiltration is the preferred flow control best management practice (BMPs), but there are no known opportunities for infiltration along the project area. Groundwater levels are high along the Renton valley floor where there are opportunities to site a pond. This was verified by monitoring piezometer wells at each pond site, so the preliminary design assumes that flow control will be provided by detention ponds and vaults. Other options may be considered as the design continues. The preliminary design has reviewed the existing flow control facilities along the 1-405 and SR 167 corridors. Few facilities existed before the 1-405 Corridor Program improvements. Three facilities were constructed within the project limit as a result of the 1-405,1-5 to SR 169 Stage 1 Widening Project (Renton Stage 1) and 1-405,1-5 to SR 169 Stage 2 Widening & SR 515 Interchange Project (Renton Stage 2): Renton Stage 1, Pond FC S2.1: located in the southwest quadrant of the SR 167 interchange with 1-405 Renton Stage 2, Talbot Pond: located south of 1-405 and to the west of Talbot Road. Renton Stage 2, Benson Pond: located on the west side of 1-405 to the north of the Benson Road Bridge crossing. The preliminary design will maintain these facilities in place without significantly changing their contributing areas or function. 1-405/SR 167 Interchan, ]irect Connector Project JARPA Form Attachment 13 STORMWATER MANAGEMENT CONCEPT FOR 1-405/SR 167 INTERCHANGE - DIRECT CONNECTOR PROJECT Page 4 of 17 Three new detention facilities will provide the additional flow control needed to mitigate the project. The following table summarizes the preliminary engineering approach for flow control to mitigate the effective new impervious area proposed by the project. There are two pond locations that have contributing areas that are larger than the equivalent impervious area that will be mitigated by the new detention ponds. • SE Quad Pond — Is required to mitigate 5.94 acres, but the preliminary design uses the HRM equivalent area on-site option to allow the full 12.04 acre contributing area to flow through the pond. A significant portion of the bypass area is pervious surface, so the peak 100 year flow rate is less than 50% of the peak flow for the impervious area being mitigated. • Renton Village Pond — Is required to mitigate 2.61 acres (TDA 2.3) plus 1.10 acres (TDA 2.4) or a total of 3.71 acres. The preliminary design allows the full 6.68 acre contributing area to flow through the pond with 0.09 acres of impervious area as on-site bypass flows. The HRM guidance for flow control modeling scenarios with off-site flow and flow-through areas also includes the `Son -site, full area option." This second option could result in different pond volumes relative to those reported in Table 2. The final determination of which option will be used is left to the final design.

-Direct Connector Project I INTRODUCTION 7. T GENERAL The Geotechnical Baseline Report (GBR) is issued as part of the Request for Proposals (RFP) for the I-405/SR 167 Interchange -Direct Connector project (Project). The GBR provides contractual representations of the geotechnical conditions that are anticipated for the Project. Contractual representations in this GBR, referred to as "baselines," are derived from geotechnical information and data collected specifically for the RFP through subsurface explorations, testing, and analysis as well review of other preexisting data and professional opinions. The results of subsurface explorations and laboratory testing are presented in the Geotechnical Data Report (GDR). The Design -Builder shall not use the GBR baselines in isolation for the planning or performance of any aspects of its Work, including and without limitation as to means, methods, techniques, sequences and procedures of construction, and safety precautions to be employed by the Design - Builder. The Design -Builder must undertake its own independent review and evaluation of the Contract Documents. The GBR was prepared based upon the geometry and physical locations of the Work anticipated in the Conceptual Plans provided in RFP Appendix M. Baseline statements included herein are not applicable to alternate locations of the Project features that may be proposed by the Design - Builder, or work that is not in conformance with the anticipated Work. These baselines, while based on significant geotechnical information, shall not be used for design or construed as a guarantee or warranty that those conditions will be encountered exactly as described herein during the construction process. Ground behavior during construction and performance of the designed project elements will depend on the construction means, metlYods, and sequences used by the Design -Builder, including equipment and materials. Where no baseline statement is provided, the Design -Builder shall assume the risk for bid and design assumptions as well as construction means, methods, and sequences. Refer to Sections 1-02.4 and 1-04.7 of the Contract General Provisions for a description of the contractual relationship between the GBR and the GDR; limitations of the subsurface information; the Design -Builder's responsibility for additional subsurface exploration; and limitations on the use of this GBR in relation to Alternative Technical Concepts and Differing Site Conditions. 7.2 SOURCES OF GEOTECHNICAL DA rA Information contained in the GDR and reference materials included in Appendix G of the RFP were used in the preparation of the GBR. 2 SUBSURFACE CONDITIONS 2.1 BACKGROUND An understanding of the geologic history and the depositional processes that produced the soil stratigraphy in the project area is useful for understanding the engineering characteristics and behavior of the deposits encountered along the project alignment and for interpreting WSDOT Geotechnical Office I-405 / SR 167 Interchange -Direct Connector Project stratigraphic correlation between subsurface explorations. Accordingly Section 2.2 is provided for contextual understanding and is not intended to be considered a baseline. 2.2 GEOLOGIC SETTING The project is within the Puget Lowland physiographic province and has experienced six or more major glaciations during the Pleistocene Epoch, between approximately 2 million and 10,000 years ago. The glaciations produced a landscape of uplands and valleys, oriented primarily in the south -north direction. The glaciations modified the lowland landscape through scour of existing deposits, and the deposition of a complex sequence of pro -glacial lacustrine deposits, advance outwash, glacial till, and recessional outwash upon older sediment bedrock. The landscape was further modified during interglacial periods when the glacial soils were eroded and re -deposited in alluvial and marine environments. The project site is located at the north end of a lowland valley that is south -north trending and abuts an upland plateau that extends to the south and east of the project area. This upland plateau, whose northern extent abuts the project area, is underlain by bedrock of the Renton Formation. The Renton Formation is a sedimentary unit consisting of arkosic sandstone, shale, mudstone, and coal (Mullineaux, 1970). The formation in the project area consists primarily of weakly cemented sandstone interbedded with siltstone with a thickness up to 2,500 feet. Coal has been mined within the Renton Formation beginning in the 19" Century and extending up to about 1957. During the Holocene Period (approximately the last 10,000 years), deposition within the project area of the Puget Lowland typically consists of flood -plain alluvium from regional river systems and local streams, valley -floor lacustrine sediments, and colluvium from landslide debris. The alluvium ranges from gravel and sand to silt and clay with related peat and other organic deposits. Lacustrine deposits that consist of peat and lesser amounts of silt, clay, and sand occupy closed depressions and other poorly drained areas on the glacial drift plain and on the valley floor (Mullineaux, 1970). During this period of time, weathering of bedrock at the margins of the upland plateau has developed a variable thickness package of residual soils. The continual accumulation of deposits within the trough has flattened the valley floor, reducing the gradient and transport energy of streams and rivers. This reduction in flow and energy resulted in the deposition of finer grained sediment within the valley. Channel migration and the aggradation of intersecting alluvial fan deposits has allowed for the localized deposit of organic soils. In recent time, man-made deposits of fill were placed over the alluvium in the valley. 2.3 ENGINEERING STRATIGRAPHIc UNITS Based on the available site data presented in the GDR, we characterize the soils across the site as being alluvium with overlying fill at some locations. Fill material, placed during the original roadway construction, was observed above the alluvium in the explorations that occurred within the existing roadway prism. Below the site soils, bedrock will be encountered. The bedrock has weathered to residual soil at some locations. A brief discussion of these Engineering Stratigraphic Units (ESUs) is presented below. Refer to the GDR for specific details. WSDOT Geotechnical Office 2 I-4051 SR 167 Interchange -Direct Connector Project • ESU 1 - Fill: Fill material, placed during development and roadway construction, was observed, and generally consisted of loose to very dense silty sand and sandy gravel with varying amounts of silt and clay. • ESU 2 —Alluvium: This ESU consists of varied sediments deposited in the project area by water. Field exploration in ESU2b encountered cobbles. This ESU can be divided into two subunits for purposes of characterization: ESU 2a -- Alluvium (Sands and Fine Grained Soils) — This ESU consists of very loose to medium dense interbedded silt with varying amounts of sand, silty sand, poorly -graded sand, and well -graded sand. This unit also contains layers of organic rich silts and peats that were observed to be greater than 5 feet in thickness. Interbeds of higher plasticity fine-grained soils were locally observed within this ESU. ESU 2b — Alluvium (Coarse-grained) — This ESU consists of dense to very dense well - graded and poorly -graded gravel with sand and varying amounts of silt. These gravels grade to well -graded and poorly -graded sand with gravel. AIthough the predominant soil types within this unit are dense sands and gravels, local interbeds of loose to medium - dense silty sand were observed to be present in thicknesses greater than 3 feet. ESU 3 — Residual Soil: This ESU consists of soils derived from in-situ weathering of ESU 4 Bedrock -- Renton Formation. Soil types represented within this ESU includes silty sand with up to 48% fines, sandy silty clay, sandy lean clay, and sandy silt. This ESU is variable in density, degree of weathering, and gradationally transitions to ESU 4 with depth. The thickness of this transition was observed to vary based on the extent of weathering. • ESU 4 — Bedrock — Renton Formation: This ESU is predominantly a grey to brown, fine to coarse-grained, slightly to moderately weathered, very weak to moderately weak sandstone. Moderately strong zones are locally present, as are interbeds of siltstone and coal. Bedding within this ESU is generally sub horizontal to gently dipping to the south at inclinations up to 15 degrees. Discontinuities are generally closely to moderately spaced and in fair condition. Zones and interbeds are variable in extent, elevation, and thickness and may not be present at some, locations. 2.4 SURFACE WATER AND GROUNDWATER To obtain groundwater elevations and seasonal variations, open standpipe piezometers and vibrating wire piezometers were installed in selected borings as indicated on the boring logs in the GDR. Data from the piezometers was collected by personnel from WSDOT. The groundwater data was collected using a combination of manual hand measurements and electronic data loggers. Groundwater elevations vary as the ground surface elevation varies. All of the recorded open standpipe piezometer readings and vibrating wire piezometer readings can be found in the GDR. 2.5 SUBSURFACE CoNDmoNS - BASELINE ASSUMpTioNS The following baseline assumptions shall be used for the project: WSDOT Geotechnical Office I-405 / SR 167 Interchange -Direct Connector Project (1) Within 5 feet of the Iocations of the GDR borings, contacts between different soil materials described and shown on the boring logs will vary by ± 2 feet from the contacts shown on the logs. (2) Within ESU 2a — Alluvium (Sand and Fine-grained Soils), soft and highly compressible soils in discontinuous layers of variable thickness are present. The Design -Builder shall assume that such materials are present beneath existing embankments of SR 167. (3) Materials from Roadway Excavation and Structure Excavation are not suitable for re- use as structural fill or roadway embankment material, except for reuse in the earth berm located at the southwest quadrant of the I-405/SR 515 interchange (See Section 9). 3 SEISMIC DESIGN The following sections describe the background information and baseline assumptions related to the seismic design of the project. 3.1 WuEwnoN POTENTIAL The liquefaction potential of saturated soils is evaluated mainly on soil index properties, density, and the depth of the deposit. The potential for liquefaction is highest for saturated, loose soil deposits. Increasing Plasticity Index (PI) decreases the potential for liquefaction. Also, clean coarse grained granular soils are somewhat less susceptible to liquefaction due to their high permeability. The potential for liquefaction also decreases with increasing density and depth. Based on the available. site data presented in the GDR, the ESU 2a - Alluvium (Sand and Fine Grained Soils) soils at the project site are locally susceptible to liquefaction below the groundwater table to a depth of up to 80 feet below the existing ground surface that exists at the time the RFP is issued. 3.2 LIQUEFACTION INDUCED SETTLEMENT Liquefaction generally causes settlement of the liquefied soil layer. These settlements can create considerable downdrag on deep foundations and damage shallow foundations, walls, utilities, and embankments. Based on the SPT data obtained from the field explorations and laboratory testing, portions of ESU 2a - Alluvium (Sand and Fine Grained Soils) are likely to settle during the design seismic event enough to create downdrag loads on foundations. There may be substantially more vertical displacement if shear failures, such as flow failures or lateral spreading occur, or where surcharge loads are present at the ground surface. Settlement will likely not occur uniformly over an area. Damage from differential settlement may occur. 3.3 INSTABILITY DUE To LIQUEFACTION Lateral ground displacements generated by liquefaction generally occurs where walls, embankments and slopes are founded on poorly consolidated natural deposits or fills. During past earthquakes, lateral displacements have pulled apart or sheared shallow and deep foundations, pipelines and other structures and utilities that transect the ground displacement zone, buckled bridges or other structures constructed across the toe, and toppled retaining walls, WSDOT Geotechnical Office 4 I-405 / SR 167 Interchange -Direct Connector Project bulkheads, etc. that lie in the path of the spreading ground. The shear strength of soil is reduced as the soil liquefies. Once it is fully liquefied, the soil strength approaches residual values. As the soil strength decreases toward its residual value, two types of slope instability can occur: flow failure, and lateral spreading. 3.3.1 Liquefaction Induced Flow Failure Liquefaction can lead to catastrophic flow failures driven by static shearing stresses that lead to large deformation or flow (Washington State Department of Transportation, 2014). Such failures are similar to debris flows and are characterized by sudden initiation, rapid failure, and the large distances over which the failed materials move (Kramer, 1996). Flow failures typically occur near the end of strong shaking or shortly after shaking. However, delayed flow failures caused by post -earthquake redistribution of pore water pressures can occur—particularly if liquefiable soils are capped by relatively impermeable layers. There is a potential for liquefaction induced flow failure to occur within the Project limits. 3.3.2 Liquefaction Induced Lateral Spreading Lateral spreading can occur when the shear strength of the liquefied soil is incrementally exceeded by the inertial forces induced during an earthquake or when soil stiffness sufficiently degrades to produce substantial permanent strain in the soil as stated in the WSDOT Geotechnical Design Manual (GDM) (M 46-03.10 , Washington State Department of Transportation, 2014). The result of lateral spreading is typically horizontal movement of non - liquefied soils located above liquefied soils, in addition to the movement of the liquefied soils themselves. There is a potential for lateral spreading to occur within the Project limits. 3.4 BAswNE AssuMpnoNs The following baseline assumptions shall be used for Work requiring seismic design: ESU 2a - Alluvium (Sand and Fine Grained Soils) below the groundwater table has the potential to liquefy during the design earthquake to a depth of 80 feet below the existing ground surface at time the RFP is issued. (1) Liquefiable soils will experience post seismic volumetric strains resulting in ground surface settlement, differential settlement, and seismic downdrag loads on deep foundations. (2) Liquefiable soils shall be considered to be unstable and susceptible to lateral spread and flow failure that will impose lateral loads and or/lateral soil displacements on project elements, (3) Liquefiable soils will experience a reduction in strength to residual strength values under liquefied conditions. (4) Saturated ESU 2a - Alluvium (Sand and Fine Grained Soils) below a depth of 80 feet to the existing ground surface that exists at the time the RFP is issued will experience strength loss as described in the WSDOT GDM. WSDOT Geotechnical Office 5 1-405 / SR 167 Interchange -Direct Connector Project 4 EMBANKMENTS, BRIDGE APPROACH EMBANKMENTS, AND RETAINING WALLS The project includes the construction of embankments for SR 167 widening and access road for the relocated waterline at the east side of SR 167, bridge approach embankments, and retaining walls. For simplicity, bridge approach embankments are henceforth considered to be embankments for the purposes of establishing baselines. 4.1 SETTLEMENT The proposed embankments and retaining walls will experience settlement during construction, at the end of construction, in the long-term, and in response to seismic ground motions. This settlement is due to the compressible nature of the alluvial deposits located below the proposed fills. Immediate settlement due to compression of non -cohesive, coarse-grained soils will occur essentially as the fill is placed. Primary consolidation of low permeability fine-grained soil layers will occur more slowly, as excess pore pressures dissipate. Secondary compression settlement of peat occurs even more slowly, taking years to complete. Where peat is present within ESU 2a — Alluvium (Sand and Fine -Grained Soils) embankments and retaining walls will be subjected to large amounts of total and differential settlement, both during construction and in the long term after completion of the Project if the peat is not removed. Ground settlement associated with embankment construction will extend tens of feet beyond the embankment limits. The effect of embankment -induced settlement will affect adjacent structures and utilities. The settlement will also cause downdrag forces to be imposed on deep foundation elements of existing or proposed structures. 4.2 STABILITY The soft and loose subsurface conditions beneath embankments and retaining walls will affect the stability of the embankment and retaining wall. An embankment and/or retaining wall bearing on the existing subsurface soils may not meet WSDOT GDM stability criteria under static and/or seismic loading conditions. Embankments and retaining walls greater than 10 ft in height bearing on ESU 2a — Alluvium (Sand. and Fine-grained Soils) will not meet minimum Factor of Safety requirements for global slope stability as outlined in the WSDOT GDM. 4.3 BASELINE ASSUMPTIONS The following baseline assumptions shall be used for Work associated with embankments and retaining walls included in the Project: (1) Within ESU 2a — Alluvium (Sand and Fine-grained Soils), soft and highly compressible soils in discontinuous layers of variable thickness are present where fills and retaining walls shall be constructed as part of the Project. (2) Embankments and retaining walls bearing on Alluvium (ESU 2a) greater than 10 ft in height will need stabilization measures to improve stability to meet minimum design criteria outlined in the WSDOT GDM. (3) The presence of peat will affect the design of retaining walls, the selection of retaining wall types and the additional height of retaining walls needed to achieve final grade after settlement. It will affect the design of fills and the need for WSDOT Geotechnical Office 6 1-405 / SR 167 Interchange -Direct Connector Project additional fill material to achieve final grade after settlement. It will affect the Design -Builder's construction schedule and construction staging choices. The Design -Builder's proposal shall either assume removal of the peat or shall assume that up to 18 inches of total settlement will occur prior to completion of the Project at any location within the project limits where peat is present. Within ESU 2a — Alluvium (Sand and Fine-grained Soils) where soft and highly compressible soils are present, the Design -Builder shall assume it will take a minimum of 150 days to attain 90 percent of primary consolidation settlement after achieving full height, or preload height, of fill placement within the Project limits. The Design -Builder shall assume it will take a minimum of 150 days to attain 90 percent of primary consolidation settlement beneath structures and foundations after the service limit state design load is attained. The Design -Builder shall assume that drainage improvements, surcharges, preloads, or other design measures that accelerate the rate of pore water pressure dissipation will need to be implemented in order to attain 90 percent of primary consolidation settlement within a duration of less than 150 days. (4) Within ESU 2a — Alluvium (Sand and Fine-grained Soils) where soft and highly compressible soils are present, the Design -Builder shall assume that secondary consolidation will occur for 75 years at rates that are variable, but commensurate with applied loadings. 5 BRIDGE FOUNDATIONS 5.1 BACKGROUND The conceptual design assumes that deep foundations will be used to support proposed new or widened bridge structures where unconsolidated soils are present. During the design earthquake ground motions, liquefaction of alluvial soils below the groundwater table will occur. The liquefaction process will cause these soils to settle and move laterally. Foundations are anticipated to be subjected to downdrag and lateral soil displacements on foundation elements resulting from liquefaction. Groundwater will be encountered in drilled shaft and shored excavations for the structures. Excavations into the soils in the project area will experience flowing (running) conditions below the groundwater table. An unshored excavation can quickly lead to large cave-ins and instability of the excavation. Use of temporary or permanent casing and drilling slurry to maintain support of the shaft excavation will be needed to control groundwater and caving in the drilled shafts. Obstructions, as defined in the WSDOT Standard Specifications (Washington State Department of Transportation, 2014) may be encountered at the drilled shaft locations. Specific information and baselines related to individual structures identified in the Conceptual Plans are provided below. 5.1.1 SR 167/405 DC Flyover Bridge The proposed SR 1671405 DC Flyover Bridge is underlain by a variable combination of all of the ESUs identified for this project. At its southern limit, a combination of ESU 1, ESU 2a, ESU 2b, and ESU 3 overlie ESU 4 — Bedrock (Renton Formation) to a depth of between approximately 84 and 114 feet. Toward the north and east along the length of the structure, the thickness of WSDOT Geotechnical Office 7 1-405 / SR 167 Interchange -Direct Connector Project unconsolidated sediment generally decreases and ESU 3 — Residual Soil and ESU 4 — Bedrock (Renton Formation) can be encountered directly beneath ESU I and ESU 2a at depths less than 30 feet. The depth to the top of ESU 4 — Bedrock (Renton Formation) should be expected to vary significantly perpendicular to the structure. Where present, ESU 2a Alluvium (Sands and Fine Grained Soils) were observed to be loose to very loose and shall be considered potentially liquefiable if it is below the groundwater table and unsuitable for bridge foundation support without ground modification. The impacts of potential liquefaction will also need to be considered in design of the foundations approaches to the Flyover. The presence of soft organic soils should be anticipated beneath the southern approaches to this structure and also in deep foundation excavations to the south of Pier 3. Foundation excavations including and north of Pier 5 will encounter ESU 4 — Bedrock (Renton Formation Sandstone) at relatively shallow depth. The presence of this shallow bedrock may impede or preclude the installation of shoring systems that include driven elements such as sheet piles and soldier piles. 5.1.2 Bridge 405/16 The Conceptual Plans call for widening or replacement of this structure. Foundation support of this structure will require the use of deep foundations. Measures are needed to protect existing bridge foundations in bridge widening (refer to RFP Section 2.13). Abutment fills for the existing structure consists of ESU l — Fill and are generally between 15 and 20 feet in height. Below the base elevation of the abutment fills, ESU 2a — Alluvium (Sands and Fine-grained Soils) overlie ESU 3 — Residual Soils and ESU 4 — Bedrock (Renton Formation Sandstone). Beneath the existing west abutment, the contact between ESU 3 and ESU 4 can be expected to be encountered between Elevation 0 and 20 feet (NAVD88). Beneath the existing eastern abutment, this contact can be expected to be encountered between Elevation 25 and 40 feet (NAVD88). In the vicinity of the structure portions of ESU 2a Alluvium (Sands and Fine Grained Soils) were observed to be Ioose to very loose and shall be considered potentially Iiquefiable and unsuitable for bridge foundation support without ground modification. The impacts of potential liquefaction will also need to be considered in design of the foundations and approach embankments. 5.2 BASELINE ASSUMPT oNs The following baseline assumptions shall be used for Work associated with the bridge foundations: (1) Deep foundations shall be required in areas not directly underlain by ESU 3 — Residual Soil and ESU 4 — Bedrock (Renton Formation Sandstone). (2) Temporary and/or permanent casing and the use of slurry shall be required during all drilled shaft excavations to maintain stability of the hole during shaft excavations. (3) Groundwater shall be encountered in all deep foundation excavations. (4) If the bridge is widened, ground improvement is required to stabilize the existing bridge (See RFP Section 2.13 for more detail on widening of Bridge 405116). WSDOT Geotechnical Office g I-4051 SR 167 Interchange -Direct Connector Project (5) Downdrag and lateral spreading due to liquefaction will affect designs of bridge foundations. 6 FISH PASSABLE STRUCTURES A new fish passable structure crossing SR 167 in the vicinity of NB 167 Line Station 334+70 is presented in the Conceptual Plans. 6.1 BACKGROUND Construction of the new Fish Passable Structure will require excavation to below the proposed flow line within the structure. Based on the available site data presented in the GDR at the location shown in the Conceptual Plans, excavations to the depth of the flow line will encounter soft and wet compressible organic soils and very loose soils of ESU 2a — Alluvium (Sands and fine-grained Soils). These soils are also present below the anticipated foundation elevation of the structure. The existing subgrade conditions are unsuitable to support fish passable structures using shallow foundations unless the soft compressible soils are mitigated or removed. The foundations will be constructed below the groundwater table. Construction of the new Fish Passable Structure will require the removal and reconstruction of a section of the existing Structural Earth Wall (SEW) at the west side of SR 167 that was constructed during the I-405 Renton Stage 2 widening project. Special precaution should be taken to avoid damage to the remaining sections of the SEW wall. 6.2 BA sEuNE Assump rioNs The following baseline assumptions shall be used for work associated with fish passable structures: (1) Over -excavation and backfill shall be necessary to provide adequate bearing conditions and to reduce the amount of immediate and long term total settlement, as well as differential settlement, to acceptable levels; and/or deep foundations shall be required. (2) Temporary construction dewatering or cofferdams shall be necessary to construct foundations for fish passable structures. (3) The construction of the new fish passable structure across SR 167 shall be finished within a single weekend closure as allowed by RFP. 7 COMPOUND CUTS IN SOIL. AND ROCK 7.1 BACKGROUND The Conceptual Plans presented in the RFP calls for north -facing cuts to accommodate the N167- N Line to the east of approximately Station 21+50. Based on subsurface exploration conducted in this area, this cut will be made in ESU 4 (Bedrock — Renton Formation) that is overlain by ESU 3 (Residual Soil). Subsurface data in the GDR indicates that groundwater will be encountered in this cut in sufficient quantities that specific measures will be required to control it during construction and for the final configuration. In addition, the presence of groundwater in ESU 3 (Residual Soil) WSDOT Geotechnical Office 9 I-4051 SR 167 Interchange -Direct Connector Project when combined with local variations in soil strength will result in local slope instability if not addressed. 7.2 BASELINE ASSUMPTIONS The following additional baseline assumptions shall be used for Work associated with the cuts required for the N167 -N Line; East of Station 21+50: (1) The cut will expose ESU 4 (Bedrock- Renton Formation) that is shallowly overlain by ESU 3 (Residual Soil) throughout its length. (2) Temporary dewatering shall be required to control groundwater for construction for 25% of the length of the cut. (3) Permanent dewatering shall be required to control groundwater for long term performance of the cut for 15% of the length of the cut. (4) Brow ditching shall be required for the entire length of the cut. (5) Supplemental drainage, i.e, subgrade drainage or midslope bench drains shall be required upslope of the N167 -N Line in order to collect and convey groundwater. (6) Supplemental drainage channels and/or localized repair shall be required for cuts in the ESU 3(Residual Soil). These measures shall be required for 15% of the length of the cut. B NOISE WALL POUNVATIONS Noise walls will be constructed at the location(s) identified in the Conceptual Plans. 8.1 BACKGROUND The Conceptual Plan calls for a cut slope into Talbot Hill at a slope of 1.5H:1 V for the roadway widening. The cut slope will be below the noise wall. The noise wall will be constructed at the crest of the proposed permanent cut slope where loose to very loose soils are present in upper layers in some areas along the noise wall alignment. The conceptual design assumes that the noise wall structures will be supported on shallow foundations or drilled shaft foundations. 8.2 BASELINE ASSUMPTIONS The following baseline assumptions shall be used for noise wall structures: (1) The soil conditions are not suitable for the use of standard plan noise walls and special designed noise walls shall be required. (2) The steepness of this cut exceeds the design assumption for the Standard Plan Noise Wall foundations. Special designs shall be required for the noise wall at the crest of the proposed cut slope (Refer to RFP Section 2.6), unless the cut slope geometry is flattened to 2H:1 V or less. 9 EARTH BERMS Three earth berms will be constructed at the locations identified in the Conceptual Plans. The first earth berm will be located at the southwest quadrant of the I-405/SR 515 interchange; the WSDOT Geotechnical Office 10 I-405 / SR 167 Interchange -Direct Connector Project second earth berm will be located at the southeast quadrant of the proposed fish passable structure crossing SR 167, while the third earth berm will be located along the east side of the proposed stream channel. 9.1 BACKGROUND The earth berm located at the southwest quadrant of the I-4051SR 515 interchange will be constructed along northbound I-405 as shown in the Conceptual Plans. A portion of the earth berm will be located on the top of the temporary extended section of the existing Culvert -48. The second earth berm located at the southeast quadrant of the proposed fish passable structure crossing SR 167 is a reconstructed section of the utility access berm for the relocated City of Renton 16" waterline. The reconstruction of the access berm is required to match the elevation of the existing access berm. The third earth berm located along the east side of the proposed Rolling Hills Creek restoration channel is a separation berm for preserving the existing wetland. 9.2 BASELINE ASSUMPTIONS The following baseline assumptions shall be used for the design of the earth berm located at the southwest quadrant of the I-445/SR 515 interchange: (l) Cuts will provide enough material for the construction of the earth berm. (2) The Design -Builder shall plan on aeration/moisture conditioning of the on-site materials from the cuts to meet compaction and moisture requirements for construction of the earth berm. (3) Soft and loose compressive materials shall be encountered in the subgrade of the earth berm. This will result in unacceptable excessive short-term and long term settlement and differential settlement, if the soft and loose materials are not removed or mitigated. (4) Since a portion of earth berm is located on top of the temporary extension of existing Culvert 48, mitigation of the effects of settlement shall be required to prevent total and differential settlement of the temporary Culvert 48 extension from exceeding the design requirements of the culvert. The following baseline assumptions shall be used for the design of the utility access berm: (5) Soft and loose compressive materials shall be encountered in the subgrade of the earth berm. This will result in unacceptable excessive short-term and long term settlement and differential settlement, if the soft and loose materials are not removed or mitigated. (6) Since the earth berm will contain the relocated waterline and a portion of the earth berm is located on top of the Olympic Pipeline Company (OFC) pipe, mitigation of the effects of settlement shall be required to prevent total and differential settlement of the relocated waterline and the relocated OPC pipe from exceeding the design requirements of these utilities. The following baseline assumptions shall be used for the design of the separation berm: WSDOT Geotechnical Office 11 I-405 / SR 167 Interchange -Direct Connector Project (7) Soft and Ioose compressive materials shall be encountered in the subgrade of the earth berm. This will result in unacceptable excessive short-term and long term settlement and differential settlement, if the soft and loose materials are not removed or mitigated. 10 DETENTION VAULT AND PONDS Two detention ponds (i.e. SE Quadrant Detention Pond and Renton Village Detention Pond), and one detention vault (i.e. SW 23rd Street Vicinity Detention Vault) will be constructed at the locations identified in the Conceptual Plans. 10.1 BACKGROUND The SE Quadrant Detention Pond (1-405 MP 2.35, Right) will be constructed inside of the northbound 1-405 to northbound SR 167 ramp loop. The Renton Village Detention Pond (I-405 MP 2.75, Left) will be construction adjacent to southbound 1-405 at the northwest quadrant of the I-405/SR 515 interchange, while the SW 23`d Street Vicinity Detention Vault (SR I67 MP 25.72, Left) will be located along the west side of SR 167 near the SW 23`d Street. The SW 23`d Street Vicinity Detention Vault will be above ground as shown in the conceptual design (see RFP Appendix H). The final location may move north or south as needed. Access from the SR 167 shoulder shall be provided. Access and placement may be impacted by soil stabilization constructed during the Renton Stage I design build job. 10.2 BASELINE ASSUMPTIONS The following baseline assumptions shall be used for the design of the SW 23�d Street Vicinity Detention Vault: (1) Within ESU 2a — Alluvium (Sand and Fine-grained Soils), soft and highly compressible soils in discontinuous layers of variable thickness are present where the detention vault shall be constructed. (2) Over -excavation and replacement or/and that deep foundations shall be necessary to provide adequate bearing and to reduce immediate settlement, long term settlement, and differential settlement to acceptable levels. (3) The design of the proposed retaining wall adjacent to the detention vault shall be influenced by the detention vault. 11 EXISTING UNDERGROUND UTILITIES Existing underground utilities are present throughout the project area. The Conceptual Plans indicate the locations of the existing underground utilities. The Design -Builder will need to coordinate with utility owners to ensure that utilities are relocated and/or protected from damage due to the Project in accordance with RFP Section 2.10. 11.1 BACKGROUND Underground utilities are present beneath and adjacent to proposed bridge structure, embankment, noise wall, and retaining wall locations. Settlement of the ground will occur during and after construction. Utilities underlying the embankments and utilities located adjacent to embankments will experience settlement and lateral movement, and may be damaged. Utilities WSDOT Geotechnical Office 12 I-4051 SR 167 Interchange -Direct Connector Project underlying retaining walls and noise walls and utilities located adjacent to retaining walls will experience settlement and lateral movement, and may be damaged. Utilities may also experience damage due to vibrations. The Conceptual Plans call for relocating the City of Renton Waterline (Ul 1335) crossing -SR 167 at SW 19`h Street (See RFP 2.10 and Conceptual Plan sheet EU3). 11.2 BASELINE ASSUMPTIONS The following baseline assumptions shall be used for Work associated with existing or new underground utilities of the Project; (1) Existing utilities could be damaged by the Project. The Design -Builder shall coordinate with utility owners and, wben appropriate, perform Work to ensure utilities are relocated and/or protected in accordance with RFP Section 2.10. (2) Underground utilities below or adjacent to new foundations are susceptible to damage due to settlement and/or vibration or both. The Design -Builder shall coordinate with utility owners and, when appropriate, perform Work to ensure utilities are relocated and/or protected in accordance with RFP Section 2.10. The following additional baseline assumptions shall be used for Work associated with the relocation of the City of Renton 16 -in Waterline crossing of SR 167 at SW 19`h Street: (3) Over -excavation and replacement shall be necessary to provide adequate bearing conditions and to reduce the amount of immediate and long term settlement and differential settlement to acceptable levels, or/and that deep foundations shall be required. (4) Temporary construction dewatering or cofferdams shall be necessary to install the waterline with a casing. (5) The design -builder shall assume the construction of the waterline across SR 167 shall be finished within a single weekend closure as allowed by RFP. 12 REFERENCES American Association of State Highway and Transportation Officials, 2011, AASHTO Guide Specifications for LRFD Seismic Bridge Design 2'° Edition, American Association of State Highway and Transportation Officials, Washington, DC.

Allen-Qiu Geotechnical Office, 47365 SUBJECT: I-405/SR 167, XL -4282 1-405/SRI 67 Interchange -Direct Connector Project Geotechnical Information for Environmental Permit Application Per you request, the following is our preliminary geotechnical information for support of the environmental permit application for the I-4051SR 167 Interchange- Direct Connector project. Please be advised that the information provided here should be only used for environmental permit application related to the Rolling Hills Creek reconstruction located on the east side of SR 167. The information is not intended as design reference or direction for the design -builder or any other purpose other than as specified above, Since there is no subsurface exploration along the proposed stream alignment for the Rolling Hills Creek reconstruction, the following preliminary geotechnical information related to design and reconstruction of the stream channel is based on the current available information in the general vicinity of the alignment and our experience regarding the general behavior of peat and organic soils which we assume to be present. The actual site conditions may be different from what we have assumed. Accordingly, this information should not be used for establishment of right of way requirements or for final civil design work. The Conceptual Design Plan calls for relocating/restoring the Rolling Hills Creek located at the east side of SR 167. The proposed new stream channel segment is located along the east side of SR 167, starting from the south ends of Culvert Nos. 42 and 44, and extending to the east end of the proposed new fish passible culvert crossing SR 167. The new stream channel will be located mostly within the existing wetland. The proposed channel will have a length of about 1400 feet, a base width of about 5 feet, and require cuts about 3 to 12 feet below the existing ground surface, Based on the information provided by the Project Office, we understand that currently there are two options in the Conceptual Design Plans for the design and reconstruction of the proposed stream channel of the Rolling Hills Creek at the east side of SR 167. WSDOT Geotechnical Office 1-405 / SR 167 Interchange -Direct Connector Project Option I is a stream channel without a separation berm, and water from the adjacent wetland and storm water from the hill side are allowed to flow into the creek. Option 2 is a stream channel with a small earth separation berm on the east side of the channel to minimize the impact to the adjacent wetland and to maintain the water level in the wetland located at the east side of the berm. There are no borings or subsurface information available along the proposed channel alignment. Based on available subsurface information outside the proposed stream alignment, we anticipate that a thick layer of very soft to soft peat or organic soils will be encountered starting at the ground surface or at a shallow depth. To complete the channel a temporary. access road may need to be designed and' constructed adjacent to the proposed channel footprint for the access of construction equipment. Over -excavation and backfill for replacement of soft peat and organic soils or loose soils in the subgrade may be necessary to provide adequate bearing conditions for the temporary access read and to reduce the amount of total and differential settlement to an acceptable level for the access road. Over -excavation and replacement will likely require the use of non -woven geotextile for soil stabilization between the native soils and the replacement section. Due to the assumed presence of compressive soils beneath the temporary access road, irregular long-term settlement may require maintenance, such as regrading to maintain the serviceability of the access road for the duration of construction. Since the channel and the access road will be constructed in an existing wetland, construction activities will likely encounter surface water and groundwater. Construction dewatering within the excavation areas may be needed, especially if construction occurs outside of summer, to control groundwater. The generation of turbid water is a concern and the contractor will likely need to implement measures to control and contain turbid water. For Option 1 (i.e. without a separation berm option), a channel side slope flatter than 4HA V in peat and organic soils on both side slopes of the channel is expected, provided proper erosion control measures will be implemented on the side slopes of the channel, such as geotextile lining anchored into the soil or Turf Reinforcement Mats (TRMs) combined with vegetation, etc. For Option 2 (i.e. with a separation berm), over -excavation and backfill for replacing soft peat/organic soils or loose soils in the subgrade will likely be necessary to provide adequate bearing conditions for the separation berm and to reduce the amount of total and differential settlement on the earth berm to an acceptable level, and to increase the stability of the side slope. For the western side slope of the channel, a side slope flatter than 4H. IV in peat and organic soils expected, provided proper erosion control measures will be implemented on the side slopes of the channel, such as geotextile lining anchored into the soil or Turf Reinforcement Mats (TRMs) combined with vegetation, etc. The inclination of the eastern side slope of the channel will depend on the extent of over -excavation and backfill, as well as the overall stability requirements of the berm and the channel side slope. Proper erosion control measures similar to ones for the western side slope should also be WSDOT Geotechnical Office 2 1-405 / SR 167 Interchange -Direct Connector Project implemented on the eastern side slope of the channel for enhancing and maintaining the stability of the side slope.
