The City of Renton Wastewater Utility (Wastewater Utility) is evaluating the condition of the Kennydale Lakeline Sewer System. The evaluation allows the Wastewater Utility to determine what is needed to properly maintain the facility and evaluate replacement options. This environmental conditions report was prepared as part of the Kennydale Lakeline Sewer System evaluation. The intent of this report is to describe the existing environmental conditions in the vicinity of the Kennydale Lakeline Sewer System corridor and identify permitting requirements for future conditions assessment work. 2.0 METHODS Confluence conducted a site visit to the Kennydale Lakeline Sewer System corridor on November 8, 2016. The purpose of the site visit was to evaluate the existing environmental and land use conditions along the Kennydale Lakeline Sewer System corridor. The site visit included visually surveying the shoreline south of Coleman Point, at the Lake Washington Flush Station northward along the shoreline to the mouth of May Creek (Figures 1 and 2). Following the site visit, Confluence used available GIS databases and maps to further clarify relevant critical areas. The following databases were reviewed: ▪ City of Renton COR Map (Renton 2016), ▪ King County iMAP (King County 2016), ▪ National Wetland Inventory (USFWS 2016), ▪ Water Quality Atlas (Ecology 2016), ▪ Priority Habitat and Species (PHS) (WDFW 2016a), and ▪ SalmonScape (WDFW 2016b). Results of the databases searches are in Appendix A. KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 2 Figure 1 Lakeline System Map 1 KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 3 Figure 2 Lakeline System Map 2 KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 4 3.0 EXISTING CONDITIONS The following sections describe the existing conditions along the Kennydale Lakeline Sewer System corridor. Photographs of the corridor are in Appendix B. 3.1 Land Use The Kennydale Lakeline Sewer System corridor runs primarily parallel to the shoreline, from south of Coleman Point, north to May Creek. The City of Renton shoreline, in the vicinity of the Kennydale Lakeline Sewer System corridor is entirely developed. Development primarily consists of residential properties with the exception of Kennydale Beach Park (Figures 1 and 2). Kennydale Beach Park is a 1.8-acre park located between the Site 1 and Site 2 manholes. The Park modifications to the shoreline include a sandy beach protected by gabion armoring along the shoreline, a pier, playground, and swimming area defined by a log boom. 3.2 Lake Washington Lake Washington provides habitat for a wide variety of fish life, including Endangered Species Act (ESA)-listed species Puget Sound Chinook salmon (Oncorhynchus tshawytscha), Puget Sound steelhead (O. mykiss), and Coastal-Puget Sound bull trout (Salvelinus malma), as well as other salmon such as coho salmon (O. kisutch), sockeye salmon (O. nerka), and resident costal cutthroat trout (O. clarki) (WDFW 2016b). A distinct population of sockeye salmon spawn on Lake Washington beaches. Spawning takes place in Lake Washington wherever suitable gravel beaches with upwelling are available (WDFW 2016c). Suitable gravel is defined as areas at least 6.7 square meters with gravel size ranging from 13 to 102 millimeters (Whyte et al. 1997). A majority of the Kennydale Lakeline Sewer System corridor has been mapped as sockeye spawning habitat (WDFW unknown date) (Figure 3). Overwater structures are present throughout the shoreline along the Kennydale Lakeline Sewer System corridor. Overwater structures consist primarily of docks associated with single-family residences. In addition, a log boom, delineating the designated swimming area at Kennydale Beach Park is also present. During the survey, substrate along the shoreline was primarily large gravel and cobble embedded with sand. While areas of upwelling were not observed during the survey, upwelling is assumed to occur based on the sockeye spawning map (WDFW unknown date) identifying the Kennydale Lakeline Sewer System corridor as suitable spawning habitat. KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 5 Figure 3 Lake Washington Sockeye Spawning Areas (WDFW unknown date) Within the Kennydale Lakeline Sewer System corridor, Lake Washington is not on the 303(d) list (Ecology 2016). However, just offshore of Coleman Point, a portion of Lake Washington is classified as Category 1 for bacteria and total phosphorus (Ecology 2016). A Category 1 is designated when an area meets the standards for clean waters. Placement of a waterbody in Category 1 does not necessarily mean that a water body is free of all pollutants, just that it meets the standards for all the pollutants for which it was tested. Just north of Kennydale Lakeline Sewer System corridor (north of May Creek), a portion of Lake Washington is classified as Category 2 for Polychlorinated Biphenyls (PCBs). A Category 2 is designated when an area is of concern. These areas have some evidence of water quality problems but not enough to require production of a water quality improvement project. There are several reasons why a water body would be placed in this category. A water body might have pollution levels that are not quite high enough to violate the water quality standards, there may not have been enough violations to categorize it as impaired according to Washington State Department of Ecology’s Approx. project area Approx. Project Location KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 6 (Ecology) listing policy, or there might be data showing water quality violations, but the data were not collected using proper scientific methods. The same area north of May Creek is on the 303(d) list for sediment because sediment bioassays failed to meet the standards. Category 5 is designated when polluted waters/sediments are present (i.e., on the 303(d) list). 3.3 Shoreline The shoreline of Lake Washington is designated as a Shoreline of the State as defined by Revised Code of Washington (RCW) 90.58.030(2). As such, the shoreline is defined as 200 feet landward of the ordinary high water mark of Lake Washington. The ordinary high water mark of Lake Washington is 25.4 feet elevation according to North American Vertical Datum of 1988 (NAVD 88). Thus the majority of the community is within the defined shoreline Along the Kennydale Lakeline Sewer System corridor, the shoreline is approximately 4,800 linear feet. The shoreline in this area is highly modified with approximately 4,500 linear feet of the shoreline heavily armored with riprap, gabion walls, or other vertical bulkheads. There are a few areas (approximately 300 linear feet in total) where bulkheads are absent and gravel dominated pocket beaches occur. These are shown in Figures 1 and 2. Riparian vegetation along the Kennydale Lakeline Sewer System corridor is primarily lawn and ornamental shrubs, with scatted trees. The riparian vegetation provides very little shading over the nearshore waters. The exception to this are the riparian areas just north of the house at 3307 Lake Washington Boulevard and the shoreline associated with 3827 Lake Washington Boulevard. On these lots, there are existing mature trees and shrubs that extend over the nearshore water, providing shade, cover, and insect drop into the lake. Photographs of the shoreline features are included in Appendix B. 3.4 Streams No streams are located within the Kennydale Lakeline Sewer System corridor. However, May Creek is located just north of the Lake Washington #2 Lift Station. May Creek is a 7-mile long tributary to Lake Washington. It is classified as a Type S stream within the vicinity of the Lake Washington #2 Lift Station (DNR 2016). The creek originates in the steep forested slopes of Cougar and Squak Mountains and in the highlands of the Renton Plateau and discharges into Lake Washington just north of the Lake Washington #2 Lift Station. May Creek provides high quality tributary habitat to Lake Washington; however, use of May Creek by salmon and other wildlife is declining due to habitat loss, erosion, sedimentation, and deteriorating water quality (King County 2001). Chinook salmon, coho salmon, and sockeye KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 7 salmon, resident costal cutthroat trout, and steelhead trout are known to use May Creek (WDFW 2016b). 3.5 Wetlands Based on the GIS information, no wetlands are within 300 feet of the Kennydale Lakeline Sewer System corridor (King County 2016, USFWS 2016, Renton 2016, WDFW 2016a). No visual indicators of wetlands (e.g., presence of hydrophytic vegetation) were observed during the survey or in photographic interpretation analysis of the Kennydale Lakeline Sewer System corridor. 3.6 Wildlife Habitat No wildlife habitat corridors or priority species sites were identified in the PHS database along the Kennydale Lakeline Sewer System corridor (WDFW 2016a). The closest PHS mapped wildlife habitat feature was an osprey nest located approximately 1,000 feet north of the mouth of May Creek, along N 42nd Place, and two bald eagle nests on the south end of Mercer Island (WDFW 2016a). During the survey, a bald eagle was observed in a mature conifer at 3827 Lake Washington Boulevard. 3.7 Steep Slopes Slopes along the shoreline range from flat (less than 15 percent slope) to gently or moderately sloping (less than 40 percent slopes), with a majority of the shoreline having 15 to 25 percent slopes (Renton 2016). 4.0 SUMMARY In summary, Lake Washington provides habitat for a wide variety of fish life, including ESA- listed species Puget Sound Chinook salmon, Puget Sound steelhead, and Coastal-Puget Sound bull trout, as well as other salmon. Within the vicinity of the Kennydale Lakeline Sewer System corridor, the nearshore environment is highly modified by the presence of bulkheads and numerous docks but is listed by Washington State Department of Fish and Wildlife (WDFW) as providing sockeye spawning habitat. The adjacent shoreline is also highly modified, with a majority of the shoreline vegetation consisting of lawn, ornamental trees, and shrubs providing nearshore shading in limited areas. 5.0 REGULATORY IMPLICATIONS Based on Confluence’s understanding of the project, several permits would be required for either maintenance of the existing line or for conducting a conditions assessment for the existing line, which will include in-water work and disturbance of the lakebed. The following sections discuss the environmental permits required for the project. The timeline for obtaining permits KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 8 for work that includes discharge of material or placement of structures within Lake Washington is 6-12 months or longer. In-water work that does not require disturbance of the lakebed or excavation on land may require a Hydraulic Project Approval (HPA) and would require local permits (see Section 5.3 for a description of the local permits). The timeline for obtaining permits for work that does not include lakebed disturbance varies from 2-12 months. 5.1 Federal Permits The US Army Corps of Engineers (Corps) is the federal government agency that would issue any federal permits needed for the proposed development. Federal permits that may be needed include the following: ▪ Section 404 Permit—Pursuant to the Federal Water Pollution Control Act ("Clean Water Act"), the Corps requires a Section 404 Permit for any discharge of dredged or fill material into Waters of the US under the jurisdiction of the Corps. Two types of 404 permits exist, an individual permit or a Nationwide permit (NWP). ▪ Section 10 Permit—Pursuant to the Rivers and Harbors Act, the Corps requires a Section 10 Permit for certain activities in, over, under, or near a Water of the US or which affects the course, location, condition, or capacity of such waters. Based on our understanding of the site and project, if any work below the ordinary high water mark of Lake Washington would need to occur, both a Section 404 and Section 10 permit would be required. In addition, actions taken by a Federal agency, must comply with Section 7 of the ESA. Section 7 of the ESA requires that actions of federal agencies should be “not likely to jeopardize the continued existence of any [listed] species or result in the destruction or adverse modification of habitat of such species.” The Corps issuing Section 404 and Section 10 permits for the proposed project would constitute a Federal action and as such, under ESA Section 7(c), the Corps is required to evaluate the potential influence of its action (issuing the permit) on listed species or their critical habitat. The JARPA is the permit application used to request both Section 404 and Section 10 permits. Issuance of Section 404 and Section 10 permits by the Corps is contingent on completion of the National Environmental Planning Act (NEPA) and ESA processes, as well Ecology’s as issuance of Section 401 Certification and Coastal Zone Management Act (CZMA) and Consistency Determination. See below for more information on Section 401 and the CZMA. 5.2 State Permits Ecology is the state government agency that would issue any state permits needed for the proposed development. State permits that may be needed include the following: KENNYDALE LAKELINE SEWER SYSTEM ENVIRONMENTAL CONDITIONS REPORT April 6, 2017 Page 9 ▪ Hydraulic Project Approval (HPA)—Pursuant to Washington Administrative Code (WAC) 22-660, WDFW requires a HPA for any project near or within a Water of the State. ▪ CWA Section 401 Certification—Prior to issuance of a Section 404 Permit or certain other federal activities, Section 401 of the Clean Water Act requires state agencies to certify that the project will comply with state water quality standards. In Washington, Ecology issues 401 Certification. State water quality standards consist of both numeric and narrative criteria designed to protect designated uses (i.e., aquatic life, recreation, water supply) of each waterbody. Ecology cannot issue a Section 401 Certification until the project has completed the State Environmental Policy Act (SEPA) process. The Section 401 Certification is also a prerequisite to Ecology issuing a CZMA Consistency Determination. ▪ CZMA—Prior to issuance of a Section 404 or Section 10 permit, Ecology ensures the project is consistent with the state Coastal Zone Management program. Based on our understanding of the project, a HPA will be required. The JARPA is the permit application used to request both an HPA and CWA Section 401 Certification. 5.3 Local Permits The City of Renton is the local government agency that would issue any local permits needed for the proposed development. Local permits that may be needed include the following: ▪ Land Use Permit ▪ Construction Permit ▪ Shoreline Use Permit or Conditional Use Permit, depending on classification of line as local or major ▪ Grading License ▪ Environmental Checklist (SEPA Determination) Unless waived by city staff, a critical areas study is required as part of the land use and construction permit applications. In addition, impacts to critical areas will also need a mitigation plan prepared as part of the construction permit application. 6.0 REFERENCES DNR (Washington Department of Natural Resources). 2016.
