Per the report, it was concluded the site has one wetland and one stream. The wetland occurs onsite and is located along the western edge of the site. The wetland is associated with Redondo Creek, which flows through the center of the wetland as a channelized, ditch -like feature. The northern portion of the stream is a non -fish bearing stream with seasonal flow (Ns) and has a 35-foot buffer. The southern portion of the stream is a non -fish bearing stream with permanent flow (Np) and has a 50-foot buffer. The wetland is a Category II wetland with 6 habitat points which has a 165-foot buffer. WETLAND REPORT The -City forwarded your request to our wetland consultant, Environmental Science Associates (ESA), for their review. ESA completed a site visit on August 28, 2019, and reviewed relevant documents. ESA prepared a technical memorandum (dated September 6, 2019) in which they concur with the wetland delineation boundaries and ordinary high-water mark (OHWM) established by the applicant's biologist. ESA also concurs with the wetland classification, Category II with 6 habitat points. However, ESA believes the entirety of Redondo Creek is a non -fish bearing seasonal stream .(Ns) with a 35-foot.buffer. In addition, the City recently updated Federal Wcry Revised Cade (FWRC) Chapter 19.145, Envirennientally Critical:4reus, Cinder the updated code, Category 11 wetlands with 6 habitat points have a 150-foot buffer. ESA recommends the report be revised to reflect these comments. The City concurs with ESA's recommendations. NEXT STEPS Please review the comments and recommendations in the enclosed letter prepared by ESA, and update the report accordingly to submit with the proposed project application. Any proposed intrusion into the wetland buffer will require a revised wetland report and review pursuant to FWRC 19.145.440. The revised report will be peer reviewed at the applicant's expense in accordance with FWRC 19.145.080(3). A new scope of work and cost estimate will be required when the revised report is submitted.

Vicinity Map of site RECEIVED JUN 20 2019 CITY OF FEDERAL WAY COMMUNfTY DEVELOPMENT American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 2 The site is an irregularly shaped accumulation of two parcels approximately 22 acres in size and located within the SW 1/4 Section 4, Township 21 North Range 4 East of the W.M. Above: King County iMap 2017 aerail photograph of the site. METHODOLOGY Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site on May 22, 2019. The site was reviewed using methodology described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), and the Western Mountains, Valleys and Coast region Supplement (Version 2.0) dated June 24, 2010, as required by the US Army Corps of Engineers and the City of Federal Way. Wetlands were rated using the 2014 WADOE Wetland Rating system for .Western Washington. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 3 Soil colors were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 1990). OBSERVATIONS Existing Site Documentation. Prior to visiting the site, a review of several natural resource inventory maps was conducted. Resources reviewed included the National Wetland Inventory Map, the NRCS Soil Survey online mapping and the WADNR Fpars stream mapping website and the WDFW Priority Habitats and Species maps for the site. Soil Survey According to data on file with the on-line NRCS Soil Survey, the site is mapped as a mix of Alderwood and Arents soils of varying slopes, and Seattle muck on the southwest portion of the site. Above: USDA Soil Survey Map of the site American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 4 Alderwood soils are moderately well drained soils formed in glacial till. Arents are Alderwood soils that have been generally disturbed through urbanization. Seattle muck soils are very poorly drained organic soils formed under sedges. Seattle Muck soils are considered "hydric" or wetland soils. National Wetlands Inventory (NWI) According to the NWI map for the site there are two linear features across the southwest side of the site. One is an emergent wetland and one is a stream.

The Watershed Company July 21, 2104 Steel lake Review A review of a study by Radeke Associates for the property directly south of 304th Street and bordering Steel Lake and Redondo Creek was reviewed by The Watershed Company in a July 21, 2014 in regards to development of Parcels #0921049012 & #092049199. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 8 Of significance in this report is the description of Redondo Creek, which also passes through the site, determined by Matt Herrera of the City at that time as a "minor stream" due to lack of fish as a result of a downstream fish barrier (see boxed text from the report below). Redondo Creek Redondo Creek is broad and flows at a low gradient through the study area (from Steel Lake north to South 304t^ Street). The OHWM of Redondo Creek appears to be largely associated with, and very similar to, the level of Steel Lake. Furthermore, while delineating Wetland A along the creek corridor, it was determined that the OHWM of Redondo Creek coincided with the majority of Wetland A boundary flags (with the exception of flag 145). This determination was based on the presence of nearby surface water (presumably slow moving Redondo Creek) during the site visit and the topography of the area; Wetland A is almost exclusively located within bed and bank features created by Redondo Creek There is a natural fish barrier located downstream of the study site (SalmonScape, FPARS, communication with Matt Herrera) that prevents access to this portion of Redondo Creek by anadromous fish species. Redondo Creek is considered a minor stream due to the natural fish barrier located downstream of the project site. This classification corresponds with the City's assessment of the stream based on communication with Matt Herrera during the on -site meeting. Minor streams require a standard buffer width of 50 feet. Above: Excerpts from the July 21, 2014 Watershed Company report Field observations Uplands The site is forested with a mature Douglas fir forest that slopes from a high point on the northeast, to a low point on the northwest. The overstory throughout the site is 2'-3' dbh douglas fir, western hemlock and smaller red alder. The understory generally consists of a mix of areas of dense salal with red huckleberry, cascara, salmonberry and some Himalayan blackberry. The site contains numerous footpaths and open transient campsites with large amounts of associated trash, shopping carts, tents and makeshift shelters, and human waste. Transients were observed occupying the site during our site visit. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc.

Soil pits excavated throughout the upland portions of the site revealed a silt loam similar in profile to the Alderwood soil series and were dry or moist during our site visit. Wetlands A single wetland is found along the western side of the site with an associated stream channel. The wetland and stream are connected to wetlands and streams to the south of South 304th Street via a 30" plastic culvert. Flow in the culvert was observed to flow northerly, and was determined not to be an "equalizing'' culvert, thus separating it from wetlands south of 304th for the purpose of rating the wetland. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 10 Wetland A Wetland A consists of a riverine and depressional, forested, scrub -shrub and emergent wetland located along the edges of Redondo Creek, an intermittent stream that flows from Steel Lake northerly through the site. The eastern edge of the wetland was flagged with pink flags labeled A 1- A23. From A23-A40, the flags denote the OHWM of the intermittent stream known as Redondo Creek. As previously noted, the 30" culvert under 304th appears to flow only in one direction (to the north). Since the culvert does not appear o act as an equalizing pipe between the wetland on -site and the wetland south of 304th, the wetland on the site was rated as a separate unit from the wetland south of 304th as is typically done with wetlands bisected by roads/culverts that have flow in one direction. The emergent and scrub -shrub portions of the wetland are located just north of South 304th Street, with the forested area along the perimeter and to the north. This emergent portion of the wetland contains a mix of speedwell, water parsley, yellow iris, broad leafed cattail, and lady fern. The scrub shrub portion contains a mix of hardhack, salmonberry and crabapple. The forested portion contains some red alder and previously mentioned species in the understory. Although the vegetation community within the wetland is fairly intact, the entire wetland is heavily degraded from trash and debris associated with the transient population on the site. The outlet of the wetland is a dug ditch that drains to the north forming the upper reach of Redondo Creek. It is possible the connection to the north was a man-made connection years ago as the northern section of the ditch is dug fairly deep with vertical sides through upland area. Soil pits excavated within this wetland revealed a black sapric organic material on the southern end of the wetland, with the north portion being a dark gravelly loam. Soils within the wetland were inundated with up to 24" of standing water on the south and saturated on the north. The ditched creek was dry from flag A25 north during our site visit. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 11 Using the US Fish and Wildlife Wetland Classification Method (Cowardin et al. 1979), Wetland A contains areas that would be classified as PEM1C (palustrine, emergent, persistent, seasonally flooded), PSS1C (palustrine, scrub -shrub, broad leaved deciduous, seasonally flooded) and PF01C (palustrine, forested, deciduous, seasonally flooded). Using the 2014 WADOE Wetland Rating system and rating the wetland as a depressional type wetland, this wetland scored a total of 20 points with 6 for habitat. This indicates a Category II wetland. Category II wetlands with 6 habitat points in the City of Federal Way have a standard 165' buffer measured from the wetland edge. (2) µtOand buffers shall be measured perpendicular from the wetland boundary as delineated and marked in the field. Buffer wldtks are estalahshed as follows: Minimum Buffer Buffer Width ButferWidth BufferWdth Width (wetland (wetland (wetland scores (wetland seaea scores 3-4habitat scores 6-7habitat 8-9habitat WeOaixd Category points) habitat points) points) points] Category I: 190 feet 190 feet 190 feet 225 feet Bogs and watiands of high conservation value Category I: 75 feet 105 feet 165 feet 225 feet Forested and based an function some CMegory II 75 feet 105 feet 165 feet 22.5 feet Category III 60 feet 105 feet 165 feet 225 feet Category N 40 feet 40 feet 40 fest 40 feet Above: Section from FWMC 19.145.420.2 regarding wettana buffers. Redondo Creek As previously discussed, Redondo Creek is a ditched feature through the center of the wetland and drains to the north towards SR 99 where it passes through a trash rack and enters a long culvert and storm drainage system before daylighting to the north and west of SR99. Since the stream is within the wetland and the 165' buffer far exceeds the buffer of the creek where it surrounds the stream, the OHWM of the creek was marked with flags A24-A40as well as AA1-AA16 on the west. American Classic Danichik/#19-141 Sewall Wetland Consulting, Inc. June 20, 2019 Page 12 The stream channel becomes evident within the wetland around flag A19, and then at A23 becomes just a linear dug ditch that is mud bottomed and approximately 10' wide. The ditch narrows to the north where it is dug more deeply through upland area and at A25 was completely dry. The channel is covered with makeshift crossings along trails made by transients, and mattresses, trash and debris clogs the ditch on the north. The trash rack on the culvert at SR99 was covered with piles of debris and trash. This stream in the past has been called a "minor stream" (non fish bearing) by the City of Federal Way under the old regulations and was considered blocked by a natural downstream fish barrier to anadromous fish. Therefore, based upon inventory data and the City's previous determination of this stream as a minor stream or non -fish bearing, this would equate to that the portion south of A23 as an Np stream, and the portion north of A23 is an Ns stream due to seasonal flow. According to FWMC 19.145.270.1, Type Np streams have a 50' buffer measured from the OHWM, and Type Ns have a 35' buffer measured form the OHWM. 19.146.270 stream buffers. ® C SHARE 11) No development may take place wttNri a stream or wi0tln the foliovil ng huller areas except as allowed within this chapter.

The property is located approximately 460 feet northeast of Steel Lake, which is designated as a Shoreline of the State. A site visit was also conducted on August 28, 2019 to review the wetland boundary and the submitted rating form. ESA previously reviewed critical areas on the adjacent parcel to the southwest (Tax Parcel 0421049057) in January 2016. That review resulted in the delineation of one wetland and one stream, both of which extend onto the parcels currently being reviewed. Results of the January 2016 review by ESA were presented to the City in the technical memo titled Jung Property Wetland and Stream Assessment for Parcel 0421049057 (dated January 26, 2017). Review of Documents ESA reviewed the Critical Areas Report — Parcels #042049012 & 9221 (dated June 20, 2019 and hereinafter referred to as the Report) prepared by Sewall Wetland Consulting, Inc. (hereinafter referred to as the Applicant's Biologist). The Report was written based on site evaluations by the Applicant's Biologist that occurred on May 22, 2019. According to the Report, one wetland occurs onsite and is located along the western edge of the site. The wetland is a riverine and depressional wetland that exhibits forested, scrub -shrub, and emergent cover types. The wetland is associated with Redondo Creek, which flows through the center of the wetland as a channelized, ditch -like feature. The stream originates from Steel Lake and flows north, under South 300 Street through a 30-inch plastic culvert, and into the site. During a review of the property south of South 304' Street, the City determined that Redondo Creek is a "minor" or non -fish bearing stream, due to a natural fish barrier that is located downstream of the site. The Report is in agreement with this determination and states that the northern portion of the stream is a non -fish bearing stream with seasonal flow (Ns) and is allotted a 35-foot buffer per Federal Way Revised Code (FWRC) 19.145.270.1. The southern portion of the stream is a non -fish bearing stream with permanent flow (Np) and is allotted a 50-foot buffer per FWRC 19.145.270.1. The wetland was categorized as a Category II wetland Critical Areas Report Review: Parcels 042049012 & 042049221, Federal Way with 6 habitat points. According to FWRC 19.145.420.2, Category II wetlands with 6 habitat points are allotted a 165-foot buffer, which greatly exceeds the required stream buffers. No other streams or wetlands are reported as occurring onsite. Results of Site Visit and Document Review ESA biologists Jessica Redman and Christina Hersum conducted a site visit on August 28, 2019 to confirm the location of the wetland boundary and observe site conditions. ESA walked the wetland boundary as well as the surrounding uplands. ESA agreed with the boundary of the wetland as delineated by the Applicant's Biologist and also categorized it as a Category II wetland with 6 habitat points. No flow was observed in Redondo Creek and the channel appeared to have been recently excavated based on the presence of freshly dug soils on the banks of the stream. Through the majority of the wetland, the stream bed of Redondo Creek was primarily composed of silty substrates and no suitable fish habitat was observed. The remainder of the site is upland forest dominated by Douglas fir and western hemlock. No other critical areas were observed onsite. According to the City's Shoreline Environment Designations Map (2011), the onsite wetland is considered an "associated wetland" of Steel Lake due to its hydrologic connection via Redondo Creek and therefore, is regulated under the City's Shoreline Master Program (SMP). The SMP was recently updated and approved by the Washington State Department of Ecology (Ecology) on August 21, 2019 and included amendments to Title 15 — Shoreline Management and Chapter 19.145 — Environmentally Critical Areas of the FWRC. The updated SMP also repealed shoreline critical area regulation under Chapter 15.10 and instead references the critical area regulations under Chapter 19.145 of the FWRC. Additionally, wetland buffer provisions under FWRC 19.145.420 were revised to reflect Ecology's latest guidance. Under the revised code and SMP, Category II wetlands with 6 habitat points are now allotted a 150-foot buffer. No revisions to stream buffers occurred with the recent SMP revisions. Review Comments and Recommendations • During the August 28, 2019 site visit, ESA staff investigated and agreed with the wetland delineation boundaries and OHWM established by the Applicant's Biologist. ESA also agrees with the wetland classification (Category II with 6 habitat points) assigned by the Applicant's Biologist. Based on conditions during the August 28, 2019 site visit, ESA believes that the entirety of Redondo Creek within the site is a non -fish bearing seasonal stream and therefore, its entire length within the site is allotted a 35-foot buffer. ESA recommends the Report be revised to reflect this. • Under the recently approved revisions to the SMP, the buffer of the onsite wetland would be reduced from 165 feet to 150 feet. ESA recommends the Report be revised to reflect this. th i:-.zc,-.�v �r ■ UM "'weti ,nd ENet,"Ad Rpores (wen i nd se ores 8-9--!}sty► tiA 44mbi poin.ti 6 7-M ii-tat Points t3eints) pfsittts value r..�...,,,.�., i. 75 fee 4 5-fe0 165 tbA feet r. {,z 60 leek 105 feet Er''+- tiE 225 fee raw,"Y-jx 9 # tt 49 feet 40 fret 40 feet Table 1 Wetland Cate ar Minimum Buffer Width (we#land Scores 3-3 habitat Buffer Width Wetland scores 6-7 Buffer Width wetland scores a-9 habitat noinfs habitat Dints Dints Cate_�ory 1 Boas and wetlands of 1tigh 250 feet 250 feet 300 feet conservation value Cate Forested and based on function 100 feet 150 feet 300 feet score Cate ❑ iI 100 feet 150 feet 300 feet category III 80 feet 150 feet 300 feet Cateao IV 50 feet 50 feet 50 feet INVOICE City of Federal Way 33325 8th Avenue S.
