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 LUA15-000512, 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: 1. 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. 3. 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 S Puget Drive and into the study area approximately 200 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 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 Q. 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 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 4 of 26 (Phalaris arundinacea), cattails (Typha latifolia) and soft rush (Juncus effuses). Shrub -dominated areas typically include Sitka willow (Salixsitchensis), 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. 11. Wetland 2.211-13 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 2.211-13 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.OL 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 2.611 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. 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 SR 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 LUA15-000522, 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 I-405/SR 167 -Direct Connector Project LUA15-000512, 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, 1-5 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 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 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 2.611, 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 LUA15-000522, CAR DATE OF PERMIT: December 4, 2015 Page 8 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, con structabiIity/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.

JARPA Sheets (Exhibit 3) were submitted with the application, prepared by WSDOT, dated June 4, 2015 (updates July 15, 2015, November 17, 2015 and November 25, 2015). 48. A Preliminary Hydraulic Design Analysis for Rolling Hills Creek Realignment was submitted with the application, prepared by WSDOT, dated January 2015. 49. A Wetland Mitigation Bank Use Memorandum was submitted with the application, prepared by WSDOT, dated May 21, 2015 (updates November 16, 2015 and November 30, 2015). 50. A Revision to Talent Ditch Report was submitted with the application, prepared by WSDOT, dated November 17, 2015. 51. A Rolling Hills Creek Restoration Conceptual Plan "Planting Plan" was submitted with the application, dated November 10, 2015. 52. The site is located in a seismic hazard area, in an area with identified protective and sensitive slopes, moderate and high landslide hazards, high erosion hazards, Rolling Hills Creek, East Fork Panther Creek, wetlands, moderate coal mine hazards, and a flood hazard area; no other critical areas exist on-site. 53. Comments were received from Karen Walter with the Muckleshoot Indian Tribe Fisheries Division (Exhibit 14); and staff responded on September 15, 2015 (Exhibit 15). No other agency or public comments were received. 54. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments have been incorporated into the appropriate sections of this report and are 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 10 of 26 attached to this report (Exhibit 18). 55. The proposed replacement of existing utility systems would be considered a replacement and/or rehabilitation of existing utilities and would be permitted outright in Table 4-3-050C.3 Exemptions — Critical Areas and Buffers. 56. The following table contains project elements intended to comply with the Critical Areas Regulations and policies, as outlined in RMC 4-3-050: CRITICAL AREA REGULATIONS CRITERA: A. COMPREHENSIVE PLAN COMPLIANCE AND CONSISTENCY, CRITICAL AREA ELEMENT: Critical areas are defined as wetlands, aquifer recharge areas, fish and wildlife habitat, frequently flooded, and geologically hazardous areas regulated by the City of Renton's Critical Areas Ordinance. Sustainability recognizes that natural systems are essential to providing both economic needs and quality of life and that actions of today have an impact on the environment which impacts the future. The quality of Renton's land, air, and water affect the health and resiliency of everyone in the community. The proposal is compliant with the following goal:. Goal L -P: Minimize adverse impacts to natural systems, and address impacts of past practice where feasible, through leadership, policy, regulation, and regional coordination. Goal L -U: Preserve, protect, and enhance the quality and functions of the City's sensitive areas including: lakes, rivers, major and minor creeks, intermittent stream courses and their floodplains, wetlands, ground water resources, wildlife habitats, and areas of seismic and geological hazards. Goal L -V: Protect the natural functions of 100 year floodplains and floodways to prevent threats to life, property, and public safety associated with flooding hazards. B. ALTERATIONS TO CRITICAL AREAS: The subject site is classified as a Critical Area on the City of Renton (COR) Map. Stream relocation may be allowed when analyzed in an accepted stream or lake assessment. The following criteria and conditions to the proposal must be met: 1. 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/SR 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 (FOF) 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 4-3-050J.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 J, 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 167 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 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. 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 11 and Category 111 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 WSDOT 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 LUA15-000522, 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 1-4051 to the inlet of a newly constructed fully fish passable structure at (approximately) milepost 25.932 along NB 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 Rolling 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 Staff Comment: Because wetland and stream impacts could not be avoided and in condition 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 (NA VD 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 conceptual 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 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 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 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 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 USACE, 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 Wetland 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 ►f regulatory approved mitigation bank. Effective June 9, 2008, the USACE (33 Code of condition Federal Regulations [CFR] 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-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 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 II 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 111, 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 would 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 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. 5. 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 FOF 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 4-3-0500.3 "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 are 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, 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. 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 I engineer demonstrates through hydrologic and hydraulic analyses performed in is met 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 floodplains or floodways 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 storm water facilities 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 LUA15-000511, 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/SR 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: 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.

The City water mains that have to be relocated, at WSDOT's expense, to accommodate the Rolling 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 (USACE) 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.

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. In addition, invasive species listed in Table 6 and any other species that competes with desirable vegetation will be controlled across the restoration site. Table 6.

Within these comments, there a specific comments that City should consider and/or respond directly: 1. We are asking for a Renton/WSDOT/MITFD planning effort to determine when and how the 19`h 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.

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-owned roadway right-of-way and the limitations of transportation funding.

Please see correspondence from Leslie Betlach dated 7/22/02 regarding future trail connections and return correspondence dated 9/10/02 from WSDOT indicating WSDOT is agreeable to a design solution along the Panther Creek wetlands that does not preclude a future trail and/or connections. Recommendations: 2. The adopted Trails and Bicycle Master Plan (2009) designated a trail crossing (east/west) of SR167 on SW 27th St.: Project sheet #106 titled, "Cascade Trail and S.W. 27th Connector." Recommendations: 3. The adopted Trails and Bicycle Master Plan (2009) designates a trail in the Panther Creed Wetlands — Project Sheet #134 titled "Panther Creek Trail." Recommendations: 4. The proposed project requires crossing/use of multiple city owned and managed parcels requiring coordinated legal property transactions either through easements and/or fee simple acquisitions. The future right for the city to complete trail improvements and corrections must be maintained. Recommendations: 5. Lake Street Open Space managed by Community Services may be one of the parcels WSDOT is proposing to "use", clarification is needed. Recommendations: 6. The Trails and Bicycle Master Plan (2009) in place as part of the EIS for the 1405 project improvements included a trail in the Panther Creek Wetlands and an east/west connection across SR 167. Recommendations: 7. Please note Environmental Assessment comments letter dated 5 22 2008 regarding trail connection under SR 167 with 4 (f) designation. Review Comments Contact: Vicki Grover 1425-430-7291 Recommendations: The adopted Renton Trails and Bicycle Master Plan and the adopted Renton Parks, Recreation and Natural Areas Plan propose a trail in the Panther Creek Wetlands (beginning north at the Lake Street Park and extending southward through the Wetlands). The City of Renton recommends adding the installation of the trail as a mitigation measure under SEPA. Attached to the Pre Application Meeting Comments dated January 22, 2015 (included in the Green Folder) is a letter (dated August 27, 2013) from the City approving the requested modification for East Valley Reconstruction. This letter also notes that' WSDOT must provide written assurance to the City that the approved cross section will be compatible with the 1405 Master Plan and that no further relocation of East Valley Road will be needed." As the City has yet to receive the written assurance, we are taking this opportunity to remind WSDOT of the need for such a letter. As the City has yet to receive a street modification request for South 4th Street and connections to the cross streets (Morris Ave S., Whitworth Ave S., Shattuck Ave S., and Davis Ave S., the City of Renton would remind WSDOT of the need for this modification request to be submitted. Version 1 1 Fire Review - Building Comments Contact: Corey Thomas ( 425-430-7024 1 cthomas@rentonwa.gov Recommendations: 1. Maintain required emergency vehicle access roadways to all areas affected by street closures and realignments. 2. Relocation/revision of all water mains and fire hydrants shall be approved by the Renton Fire Department. EXHIBIT 18 Ran: December 02, 2015 Page 1 of 1
