Raedeke TECHNICAL MEMORANDUM June 25, 2019 To: Mr. Martin Reimers Concept Architecture, LLC. 1712 Pacific Avenue, Suite 107 Everett, WA. 98201 From: Kolten T. Kosters, M.S., PWS Wetland Scientist Raedeke Associates, Inc. Bill Taylor, M.S. Aquatic Scientist Raedeke Associates, Inc. RE: 4th Dimension Renton Stream and Wetland Reconnaissance (RAI Project No. 2019-052-001) Per your request, Raedeke Associates, Inc. staff conducted a site investigation of the 4th Dimension project site located at 4502 NE 4th Street in the City of Renton, Washington. The purpose of our June 4, 2019 site investigation was to document the existing piped stream channel, and to document any off-site streams or wetlands within the immediate vicinity of the project site as part of the applicant’s request for a stream variance per City of Renton (2019a) code requirements. We caution that the discussion of regulatory implications, which represent our best professional interpretation and analysis, should not be construed as the final authority. Additional information may be obtained from agencies with jurisdictional responsibility for, or interest in, the site. PROPERTY LOCATION The 4th Dimension Renton project site consists of an approximately 0.55-acre parcel located at 4502 NE 4th Street in the City of Renton, Washington (Figure 1). The project site is identified as King County Tax Parcel No. 1023059068. This places the project site in a portion of Section 10, Township 23 North, Range 5 East, W.M. Parcel maps retrieved on-line from King County depict the property boundaries. Mr. Martin Reimers Concept Architecture, LLC June 25, 2019 Page 2 METHODOLOGY We based our identification of ordinary high water mark (OHWM) of streams on the definitions provided by the Washington State Shorelines Management Act of 1971: “that mark that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from that of the abutting upland, in respect to vegetation.” (RCW 90.58.030(2)(b) and WAC173-22-030(6)). The OHWM will be delineated using procedures outlined in the Washington Department of Ecology (1994) Shoreline Administrators Manual. We based our investigation upon the guidelines of the U. S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory 1987) and subsequent amendments and clarifications provided by the USACE (1991a, 1991b, 1992, 1994), as updated for this area by the regional supplement to the USACE wetland delineation manual for the Western Mountains, Valleys, and Coast Region (USACE 2010). The USACE wetlands manual is required by state law (WAC 173-22-035, as revised) for all local jurisdictions, including the City of Renton. BACKGROUND RESEARCH Prior to conducting our site visit, we reviewed existing background maps and information for the project site from the U.S.D.A. Natural Resource Conservation Service (NRCS 2019) Web Soil Survey, the U.S. Fish and Wildlife (USFWS 2019) National Wetland Inventory (NWI), City of Renton (2019a) COR Maps in order to assist in our determination of whether wetlands or streams were present within the property or its vicinity. We also reviewed the Washington Department of Fish and Wildlife (WDFW 2019b) Salmonscape database, and the WDFW (2019a) Priority Habitat and Species database in order to determine if any streams or priority fish and wildlife habitat were in vicinity of the project site. In addition, we also reviewed current and historical aerial photographs (Google Earth 2018) to assist in the definition of existing plant communities, drainage patterns, and land use. The USDA NRCS (2019) Web Soil Survey shows the north half of the project site mapped as Alderwood gravelly sandy loam and the south half mapped as Everett gravelly sand loams. While not hydric, both Alderwood and Everett gravelly sandy loams soil series may include minor components that are hydric such as Mckenna, Shalcar, and Norma. The USFWS (2019) National Wetland inventory map does not depict any wetlands or streams. The City of Renton (2019) Maps database shows an off-site stream located 80 feet to the east of the project site and a wetland also associated with the stream channel Mr. Martin Reimers Concept Architecture, LLC June 25, 2019 Page 3 approximately 230 feet east of the site. The stream is also mapped as originating from an off-site wetland complex located further to the east. The King County (2019) does not depict any wetlands or streams in the immediate vicinity of the project site. The nearest mapped wetland is depicted approximately 1,000 feet east of the project site. The nearest stream is approximately 750 feet north east of the site and may be associated with that wetland. The WDFW (2019b) Salmonscape database does not show any streams on the project site. The nearest stream depicted on Salmonscape is located approximately 900 feet west of the project site, to the south of NE 4th street. The WDFW (2019a) Priority Habitats and Species database does not show any mapped occurrence of endangered, threatened, or sensitive species or their habitat in the immediate vicinity of the project site. RESULTS During our June 4, 2019 site investigation, we did not identify any wetlands or surficial streams on the project site. The south half of the project site is currently developed and contains an existing house, yard, and gravel driveways and parking areas. We observed an off-site stream channel approximately 80 feet east of the project site (Figure 2). The stream channel appears to be associated with an off-site wetland complex approximately 180 feet east of the project site. In general, the property slopes to the north decreasing in elevation by approximately 5 feet at its lowest point in the central portion of the site. The majority of the project site is currently undeveloped and dominated by a dense thicket of Himalayan blackberry (Rubus armeniacus, FAC) and Japanese knotweed (Polygonum cuspidatum, FACU) (Sample Plot 1). Several large approximately 18 to 20 (dbh) inch balsam poplar (Populus balsamifera, FAC) trees are located along the west and south parcel boundary. Additional species observed scattered across the site include reed canarygrass (Phalaris arundenaea, FACW), orchard grass (Dactylis glomerata¸FACU), Kentucky bluegrass (Poa pratensis, FAC), and common dandelion (Taraxacum officinale, FACU). Soils throughout the project site generally consist of up to 8 inches of dark grayish brown (10YR3/2) sandy loams over dark brown (10YR 3/3) sandy loams to a depth greater than 12 inches. The onsite soils are very compacted and may have been historically manipulated from site clearing and piping of the stream channel that historically crossed the central portion of the site. During our site investigation, the soils did not exhibit any indicators of wetland hydrology (e.g. water table or soil saturation) within the upper 20 inches of soil profile. In addition, we did not observe any secondary indicators typically Mr. Martin Reimers Concept Architecture, LLC June 25, 2019 Page 4 associated with wetlands such as drainage patterns, drift deposits, or water stained leaves (Sample Plot 1). Stream Channel We observed stream channel located off-site to the east of the project site. The stream channel is approximately 4 feet in width, and was not flowing at the time of our investigation. The stream channel enters an approximately 24-inch diameter plastic pipe that extends underneath the central portion of the project site (Figure 2). The flow continues through a series of drainage pipes for approximately 1,100 feet prior to discharging to a stream channel southeast of NE 4th Street, approximately 900 feet west of the site. Based on our review of historic aerial imagery, the onsite portion of the stream appears to have been piped sometime between the late 1960s and early 1980s as part of site development. Aerial imagery available from the Historic Aerials (2019) website also suggests that the stream historically flowed through the central portion of the project site and continued off-site further to the west. The off-site stream appears to meet the criteria of a Type Ns (non-fish bearing, seasonal) stream. The City of Renton (2019b) code Section 4-3-050(G) requires a 50-foot-wide standard buffer for Type Ns streams. As such, no portion of the stream buffer appears to extend onto the project site (Figure 2). Off-Site Wetland During our site visit, we noted that the off-site stream channel to the east originates from a wetland complex located further to the east (Figure 2). The wetland is located in a depression located approximately 260 feet north of NE 4th street and west of 138th Avenue SE. The wetland contains a palustrine, forested (PFO) vegetation community and appears to seasonally pond. The wetland outlets to the west into the off-site stream channel. We completed a preliminary wetland rating for the off-site wetland using the WDOE 2014 wetland rating methodology as required by the City of Renton. Based on our analysis, the wetland meets the criteria of a Category III because it scored a total of 17 points (4 points for habitat function) on the wetland rating form. The City of Renton (2019b) code requires a 50-foot-wide standard buffer for Category III wetlands that score 4 points for habitat function. As such, the off-site wetland buffer does not extend onto the project site. Wildlife We did not observe any evidence of nesting within the site or vicinity by hawks, eagles, great blue herons, or other species of concern during our field investigation. Site conditions were generally not suitable for large raptor nesting, as very few trees were on Mr. Martin Reimers Concept Architecture, LLC June 25, 2019 Page 5 site, none of which have branching patterns conducive to supporting large stick nests. In addition, the Washington Department of Fish and Wildlife (WDFW 2018a) Priority Habitats and Species (PHS) database shows no mapped occurrences of endangered, threatened, sensitive, or other priority species or habitats on the site or vicinity. We did not observe any woodpeckers or their forage habitat or nesting cavities on site. PROPOSED VARIANCE The project is requesting a variance to allow the piped stream to be redirected to a new surface channel that will be constructed in the central portion of the site (Concept Architecture LLC 2019). The new stream channel will be spanned by a new building that will be constructed over the open the top of the channel (Figure 3). Currently, the 24- inch diameter culvert and pipe servicing the property are not adequate to accommodate water from the stream during heavy storm events. This results in water overtopping the culvert and ponding in the central portion of the site. The proposed building would be constructed with an open space under the building footprint to accommodate the new stream channel and provide additional storage during storm events. The project would also install a new 30-inch dimeter culvert to the existing storm system on Bremerton Avenue. The new building will have access under the structure for maintenance and cleanout, and pumping access per City specifications. The overall project is anticipated to improve the flow of drainage across the site, and reduce potential impacts from flooding on neighboring properties. Approval of this variance will not impact the public or any properties as the existing system is currently inadequate to convey flows across the site. The proposed project is not expected to adversely affect stream functions as the stream flow which would continue to flow through approximately 1,100 feet of stormwater pipes prior to discharging into a stream 900 feet southeast of the project site (City of Renton 2019b). The proposed project is anticipated to improve drainage to the project site and neighboring properties, thus reducing the probability of future impacts. The requested variance is the minimum needed in order to accommodate development of the site and simultaneously maintain the drainage system. All other options including upsizing of the entire system so the storage would not be needed, or constructing additional drainage structures on site or off-site will be more costly and destructive to the site and surrounding properties. The proposed daylighting of the stream channel and upgrade of the outlet is the simplest solution to provide adequate flood storage while still achieving economical use of the property.
