An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the City of Redmond identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply" and indicate the reason why the question “does not apply”. It is not adequate to submit responses such as “N/A” or “does not apply”; without providing a reason why the specific section does not relate or cause an impact. Complete answers to the questions now may avoid unnecessary delays later. If you need more space to write answers attach them and reference the question number. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the City can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. When you submit this checklist the City may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact.

BACKGROUND Question List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. • Critical Areas Report – Prepared by Parametrix (August 2018) • Biological Evaluation – Prepared by Parametrix (March 2018) • JARPA – Prepared by Parametrix (March 2018) • Permit Matrix – Prepared by Parametrix (January 2018) • Geotechnical Report – Prepared by GeoEngineers (March 2018) • Archaeological Assessment – Prepared by Stephenie Kramer, Michael Shong, Breanne Taylor, and Robert Kopperl (March 2018) • Culvert Analysis Report – Prepared by Tetra Tech (August 2018) Question #11: List any government approvals or permits that will be needed for your proposal, if known. • Clean Water Act Section 404 Permit (Corps) • National Historic Preservation Act Section 106 Consultation (Corps, DAHP) • Clean Water Act Section 401 Certification (Ecology) • Endangered Species Act Section 7 Compliance (Corps, NOAA Fisheries, USFWS) • Hydraulic Project Approval (WDFW) • NPDES Construction Stormwater General Permit (Ecology) • Site Construction Permit (City of Redmond) • Clearing and Grading Permit (City of Redmond) (potentially) ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 2 November 6, 2018 Question #12: Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The proposed project includes the following improvements: repaving the existing road section on Willows Road between NE 90th Street and NE 124th Street (approximately 2.14 miles), upgrading curb ramps to be compliant with the Americans with Disabilities Act (ADA), and replacing two culverts that span Willows Road—one at Willows Creek and one at Gun Club Creek. Approximately 587,250 square-feet of roadway will be repaved and approximately 4,410 square-feet of pavement will be required for ramp upgrades. Road improvements including repaving and curb ramp upgrades are categorically exempt from SEPA per Washington Administrative Code (WAC) 197-11-800. The new culverts will be the same general footprint as the culverts being removed, though additional width will be added to improve fish passage. At Willows Creek, the existing 43-inch by 27-inch corrugated metal pipe (CMP) arch culvert will be replaced with a 12-foot-wide by 5-foot-high three-sided box culvert, resulting in approximately 1,300 square-feet of temporary impacts. At Gun Club Creek, the existing 36-inch by 22-inch CMP arch culvert will be replaced with a 10-foot-wide by 4-foot-high four-sided box culvert. An existing water line will be expanded to 1 foot in diameter and lowered to a depth of 7 to 8 feet below the surface, parallel to Willow Road. At Gun Club Creek there will be approximately 2,450 square-feet of temporary impacts. In considerations for future Willows Road widening, this culvert design should be forward compatible. The culverts at Willows and Gun Club Creek are stream simulations culverts with width determined by the natural ordinary high water width of each stream. Lengthening the culverts in the future will not change the design width of these structures. The culverts height has been optimized to meet permitting requirements for fish passage culverts, while allowing for the many utilities in this corridor with limited coverage. The roadway can be widened by lengthening the proposed fish passage culverts without replacing the sections of culverts being built as part of this project assuming there are no changes to the regulatory guidelines and/or other design criteria between now and the proposed roadway widening. The topography of each creek steepens to the west, so if the roadway is extended in that direction, there will likely be extensive grading of the stream channel required to tie the elevation of the creek in with the new culvert inlet and maintain freeboard. This work would be required with the existing culverts or the proposed fish passage culverts. However, a full evaluation of the impact of roadway widened was not performed and other design issues may affect the need to modify the culvert to accommodate a future roadway widening project. Question #13: Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The proposed project is located in the City of Redmond, King County, Washington primarily within the right-of-way (ROW) of Willows Road between NE 90th Street and NE 124th Street (S2 and S3, T25N, R5E and S27 and S34, T26N, R5E, respectively). Portions of the project will take place outside the ROW along Willows Road for which easements will be required. The north end of the project area (between NE 116th Street and NE 124th Street) is bordered by the Sammamish Valley Park and agricultural land to the east, and undeveloped forest land with scattered residential and commercial structures to the west. The central portion of the project area (between NE 100th Court and NE 116th Street) is bordered by the Willows Run Golf Course and a church parking lot to the east, and commercial/office buildings, associated parking areas, and some scattered undeveloped forest land to the west. The ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 3 November 6, 2018 southern end of the project area (between NE 90th Street and NE 100th Court) is surrounded by commercial/office buildings and associated parking areas. The proposal area is located within the Sammamish River, Willows Creek, and Peters Creek watersheds. These watersheds are within Water Resource Inventory Area 8. The topography in the vicinity of the project area is relatively flat along the entire project corridor. B. ENVIRONMENTAL ELEMENTS 1. Earth Question #1d: Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. The proposed project site has moderate risk of liquefaction because of the relatively high groundwater and presence of loose- to medium-dense alluvial deposits below the site. The site has a low risk of liquefaction-induced lateral spreading because of the presence of development between the site and the Sammamish Slough. The site has a low risk for seismically-induced landslides due to the relative flatness of the site. Question #1e: Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. Temporary fill (bags of gravel) will be used for cofferdams at Willows Creek and Gun Club Creek during construction of new culverts. Both creeks will be excavated and recontoured with stream substrate at the culvert approaches to accommodate wider culverts. Approximately 16 cubic yards are estimated at Willows Creek and 15 cubic yards at Gun Club Creek. Native soil will be used to the extent possible and local, commercial sources will be used for any additional fill needed. Question #1h: Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Proposed measures to reduce or control erosion include, but may not be limited to: implementing construction phasing that minimizes the amount of earthwork that exposes the ground surface to erosion; implementing a TESC plan, including sediment-control BMPs such as silt fences, check dams, sediment traps, sedimentation basins, and flocculation methods; using erosion-control practices (seeding, mulching, soil conditioning with polymers, use of sod stabilization, erosion-control blankets, vegetative buffer strips, and preservation of trees with construction fences); using construction entrances, exits, and parking areas that reduce sediment tracking onto public roads; and performing routine inspections of erosion-control and sediment-control BMPs and subsequent BMP maintenance. 2. Air Question #2a: What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Emissions will be generated by paving equipment during the repaving of Willows Road, in addition to emissions from construction equipment during culvert replacement. There are no operational emissions associated with the ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 4 November 6, 2018 proposed project except for those from automobile traffic on Willows Road. Traffic conditions on Willows Road are not expected to change as a result of the project as it will not increase the current traffic capacity of the road. Question #2c: Proposed measures to reduce or control emissions or other impacts to air, if any: BMPs to prevent fugitive dust emissions will be in place throughout project construction activities. BMPs would implement measures such as: • Spraying exposed soils with water to reduce airborne dust • Covering dirt, gravel, and debris piles as needed to reduce dust and windblown debris • Requiring contractors to keep machinery in good mechanical condition, reduce idling time, and use equipment with emission controls, where feasible, to minimize exhaust emissions 3. Water a. Surface Question #3a Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The proposed project is in the vicinity of Willows Creek, Gun Club Creek, and Wetlands A through E. Figures showing the locations of the creeks and wetlands are included in the Critical Areas Report. Willows Creek flows northeasterly from wetland areas through the culvert under Willows Road between NE 95th Street and the Puget Power Trail, followed by an open channel, then through another recently replaced culvert under the Redmond Central Connector Trail. Willows Creek then flows through Wetland C and continues easterly through a series of piped and open channel sections and through a culvert under the Sammamish River Trail, which outfalls into the Sammamish River. Gun Club Creek flows northeasterly from wetland areas through a culvert under Willows Road between the Puget Power Trail and NE 100th Court into Wetland B, followed by a culvert under NE 100th Court. Gun Club Creek continues through Wetland A and through another culvert under the Overlake Christian Church parking lot driveway. Gun Club Creek then flows easterly in a linear ditch along NE 100th Court and through a culvert under the Sammamish River Trail, which outfalls into the Sammamish River. Wetland A is a narrow, ditched wetland located north of NE 100th Court between Willows Road and the Redmond Central Connector Trail. Wetland B is a narrow, ditched wetland located south of NE 100th Court between Willows Road and the Redmond Central Connector Trail. Wetland C is a depressional wetland located north of the Willows Road/NE 95th Street intersection and east of the Redmond Central Connector Trail. Wetland D is a narrow, ditched wetland located north of NE 95th Street between Willows Road and the Redmond Central Connector Trail. Wetland E is a slope wetland located west of Willows Road and immediately south of Willows Creek. Question #3a Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, the culvert replacement work will occur within Willows Creek and Gun Club Creek. The proposed project will temporarily divert stream flows in order to replace the existing culvert structures with wider culverts to improve ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 5 November 6, 2018 fish passage (see temporary bypass details below). Portions of Wetlands B, D, and E will be temporarily disturbed during project construction. These wetland areas will be restored following construction. Question #3a Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Temporary fill (bags of gravel) will be used for cofferdams at Willows Creek and Gun Club Creek during construction of new culverts. Both creeks will be excavated and recontoured with stream substrate at the culvert approaches to accommodate wider culverts. Approximately 16 cubic yards of excavation are estimated at Willows Creek and 15 cubic yards at Gun Club Creek. Native soil will be stockpiled and used to the extent possible and local, commercial sources will be used for any additional fill needed. Question #3a Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. Yes. In order to remove the existing structures and install new structures, it will be necessary to isolate the work area and bypass stream flows around the construction area. The City proposes to divert the entire flow of Willows Creek via a minimum 24-inch-diameter, 105-foot-long bypass pipe; similarly, Gun Club Creek will be diverted via a minimum 18-inch-diameter, 125-foot-long bypass pipe. Prior to installing the temporary bypass pipes, fish will be removed by qualified biologists from the sections of the streams to be dewatered. It is anticipated that all in- water work for the culvert replacement portion of the project will take place during the in-water work window (July 1 through September 30). b. Ground See SEPA Checklist. c. Water Runoff Question #3c Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The primary source of water to the wetlands in the project vicinity, which drain to Willows Creek and Gun Club Creek, is runoff from the adjacent trail and roads. The project will not generate any new impervious surfaces; therefore, existing runoff patterns will be unchanged from existing conditions. The Gun Club Creek culvert has a stormwater discharge into the culvert via a catch basin. During construction, runoff and stormwater at the Gun Club Creek culvert will be diverted/pumped to an upstream wetland/detention facility until construction of the new culvert is complete. Upon completion, stormwater will be redirected to the new culvert. Question #3d: Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: The proposed project will be designed to meet requirements of the Washington State Department of Ecology’s (Ecology) current stormwater manual. A Stormwater Prevention Plan (SWPP); Spill Prevention, Control, and ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 6 November 6, 2018 Countermeasures Plan (SPCC); and a Temporary Erosion and Sedimentation Control Plan (TESC) will be developed for the proposed project. 4. Plants Question #4b: What kind and amount of vegetation will be removed or altered? Approximately four trees will be removed from upstream and seven trees from of the existing Willows Creek culvert to accommodate the wider culvert replacements. Trees to be removed include red alder and black cottonwood. No trees are located within the disturbance areas surrounding the Gun Club Creek culvert. Riparian vegetation surrounding the culverts will also be removed for construction grading. Question #4e: Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Areas disturbed by construction activities will be stabilized with coir, mulch, or similar methods, and then planted. The project proponent will replant cleared areas adjacent to the culvert areas and will also monitor those plantings for a minimum of 5 years post-construction to ensure survival. All trees removed from the riparian area will be replaced with native trees and shrub species. 5. Animals Question #5b: List any threatened and endangered species known to be on or near the site. The following Endangered Species Act-listed species were identified as potentially present in the project area: bull trout, marbled murrelet, streaked horned lark, yellow-billed cuckoo, North American wolverine, Puget Sound ESU Chinook salmon, and Puget Sound DPS steelhead (ESU = environmentally significant unit, DPS = distinct population segment). However, none of these species are expected to occur in the project action area. Listed salmonid species, including Chinook salmon, bull trout, and steelhead are precluded from Gun Club Creek and Willows Creek by inadequate habitat conditions for spawning, rearing, or migration; passage barriers; and inadequate flow regimes. Surveys conducted in both streams have also failed to identify use by these species. Question #5d: Proposed measures to preserve or enhance wildlife, if any: Prior to the installation of the temporary stream bypass system, qualified biologists will remove fish from the portion of the channels to be dewatered. Fish salvage will take place in accordance with current Washington State Department of Transportation (WSDOT) Fish Exclusion Protocols and Standards. The project proposes to replace removed trees with native trees and shrubs, and will monitor the plantings to ensure the establishment for a period of 5 years post-construction. The proposed replacement plantings are anticipated to increase habitat complexity and contribute to stabilization of streambanks in the project area over the long term. 6. Energy and Natural Resources See SEPA Checklist. ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 7 November 6, 2018 7. Environmental Health Question #7a Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. The Olympic Pipeline Company transmission pipeline runs parallel to Willows Road a half mile to the west. The project will not impact this transmission line. Several underground storage tanks (USTs) are located in the project vicinity. One operational UST containing diesel is located at the York Pump Station (operated by King County Water Treatment Division) at the intersection of Willows Road NE and NE 124th Street. There are four operational USTs containing unleaded and leaded gasoline located at the Arco gas station at the intersection of Willows Road NE and NE 90th Street. The project does not propose any ground-disturbing activities in the areas surrounding these USTs, therefore they are not anticipated to impact the project. Question #7a Proposed measures to reduce or control environmental health hazards, if any: The project proposes the following precautions to prevent the potential for contamination of sensitive areas: daily inspections of vehicles operated within 100 feet of any stream or waterbody; vehicle repairs for any leaks before resuming operations; use of staging areas for vehicle storage while not in use; and vehicle fueling at least 150 feet from any streams. Additionally, an SPCC plan will be implemented for the proposed project and spill response equipment will be on-site to respond to any potential fluid leakage. 8. Land and Shoreline Use Question #8e: What is the current zoning classification of the site? Willows Road is surrounded by parcels with the following zone classifications: business park, manufacturing park, urban recreation, and park and open space. The Willows Creek culvert is on a parcel zoned as business park and the Gun Club Creek culvert is on a parcel zoned as manufacturing park. Question #8h: Has any part of the site been classified as a critical area by the city or county? If so, specify. The City of Redmond classifies fish and wildlife habitat conservation areas (FWHCAs), wetlands, frequently flooded areas, critical aquifer recharge areas, and geologically hazardous areas as critical areas in Redmond Zoning Code (RZC) 21.64. Gun Club Creek and Willows Creek are designated as FWHCAs because they are “Waters of the State”. According to City mapping, the majority of the project area is mapped as Wellhead Protection Zone 4, with an area of Wellhead Protection Zone 2 mapped along the east side of Willows Road immediately north of NE 90th Street. City mapping also identifies nearly the entire project area as a seismic hazard area. The draft geological study states that the project area has a moderate risk of liquefaction. Additionally, a seismic hazard Environmentally Critical Area (ECA) identified by King County encompasses the northern portion of the project area along Willows Rd NE between NE 116th Street and NE 124th Street. Details regarding the locations, project impacts, and regulatory implications of critical areas are included in the Critical Areas Report (August 2018). ---PAGE BREAK--- ATTACHMENT A (CONTINUED) Tetra Tech 553-2577-018 SEPA Checklist Attachment A 8 November 6, 2018 9.
