Jones, has a B.S. degree in Biology and 35 years full-time work as a wetland scientist in Western Washington. His resume is attached to this report. 2 5.0 Methodology The wetland assessment and delineation were performed using the 1997 Washington State Wetlands Identification and Delineation Manual (DOE, 1997) and the U.S. Army Corps of Engineers “Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coastal Region (COE. 2010). The Routine Small Area Methodology is “used when the project area is small, plant communities are homogeneous, plant community boundaries are abrupt, and the project is not controversial.” The wetland determination was based on the presence of the three criteria for jurisdictional wetlands, hydric soils, wetland hydrology, and hydrophytic vegetation. Wetlands were rated with the Washington State Department of Ecology 2014 wetland rating methodology (Hruby, 2014). The assessment included a review of the National Wetland Inventory, the Department of Natural Resources Forest (DNR) FPARS stream typing maps, the City of Renton Critical Areas Map, the WDFW Priority Habitats and Species (PHS) online report, and the USDA National Resource Conservation Service’s online soil survey. The field determination and wetland delineation were performed on November 14, 2022. The weather was overcast and raining both days. The wetland scientist was Jeffery S. Jones. The wetland boundary was originally flagged and delineated in May of 2022 by The Watershed Company. The Watershed Company wetland delineation was checked and found to be accurate. Their wetland boundary flags are still in place. The wetland flags are numbered A-1 thru A-28 (see Critical Area Map). There are two sample locations identified as SL-1 and SL-2. 6.0 Wetland Determination, Classification, Rating, and Regulatory Requirement There is a large wetland, identified as Wetland A, on the south side of tax parcel 9358 and diagonaling through the west half of tax parcel 9360. The wetland is identified on the attached Water Class and Wetland City Inventory Map, the WDFW PHS online report, and the National Wetland Inventory, see the attached maps. The wetland extends from N.E. 10th St. south to N.E. 4th Court. The wetland is mapped as Alderwood gravelly sandy loam soil series, see the attached Soils Map. However, Alderwood typically has inclusions of hydric soils in depressions and drainage patterns. Sample location-1 (SL-1) represents the upland slope above Wetland A, see the attached data sheet. At SL-1, soils profile is dry and does not meet the hydrology criteria. Soils have a 10YR 4/3 brown matrix at 10 inches and non-hydric. The dominant plants species are greater than 50% FAC or wetter plant species and meet the criteria for a hydrophytic plant community. Therefore, SL-1 is not wetland. SL-2 represents Wetland A, see the attached data sheet. The soil profile is a 10YR 2/1 black silt loam. All one chroma soils are hydric. The soils profile was saturated to the soil surface. Saturated soils meet the criteria for wetland hydrology. The plant community is strongly positive for wetlands. Dominant plants are 100% FAC or wetter species. Wetland A rates as a Category II, see the attached rating form and rating figures. The HGM classes are Riverine and Depressional, when these two HGM’s are present the Depressional rating sections are used for the rating (Cowardin, 1992). The total score is twenty-one points, and the habitat score is 6 points. The wetland buffer requirement is 150 feet, RMC 4-3-50G. 7.0 Stream Determinations, Classifications, and Regulatory Requirements Honey Creek flows through the wetland in a north-south direction. This portion of Honey Creek is a Type F stream according to the DNR FPARS water typing map, see attached. The stream buffer requirement for a Type F stream is 115 feet, RMC 4-3-50G. Honey Creek was not located by the surveyor because it is approximately 80 feet offsite. There is also a tributary to Honey Creek that flows east to west south of wetland boundary flags A-19 to A-28. The source of this tributary appears to be a stormwater pond. The tributary is a Type Ns stream with a 50-foot buffer. These stream buffer do not extend beyond wetland buffers. 8.0 Functions and Values of the Wetland Wetland A is a Palustrine Forested (PFO) wetland (Cowardin, 1979). There are at least two small ponds within the wetland. Wetland A provides significant flood retention and mediation ability. Wetland habitat functions are moderate because the stream is non-fish bearing and there is significant development around the perimeter of the wetland, breaking access to other habitats. The wetland contains a large number of snags and lots of woody debris that provide wildlife habitat for shelter, feeding, nesting, and roosting. Habitat interspersion is low because there is only one Cowardin class. There is at least one quarter acre of seasonally inundated thin-stemmed vegetation or wood branches for amphibian egg-laying structures. Wetland A and the surrounding uplands are not habitat for any priority species, and there are no priority habitats other than those identified in the wetland. 9.0 Wildlife Observations Only one incidental wildlife species was observed, the American robin (Turdus migratorius). The PHS online report does not identify any priority species, see attached PHS report. 10.0 Impact Assessment No direct impacts to wetlands, streams, or priority habitats will occur as a result of the proposed development. Impact to the wetland buffer is unavoidable and will necessitate a variance to the code for tax parcel 102305-9360. It may not be possible to provide the minimum buffer allowed in the code, in which case a variance to the code would be required. An impact analysis report will be prepared along with the mitigation plan and other variance submittal documents. 11.0 No Net Loss The proposed project will not result in any loss of wetland area or functions. “No net loss” is a federal, state, and local jurisdiction goal that the further loss of wetlands and wetland functions will not occur. Governor Booth Gardner’s Executive Order 89-10 states, “Section 1. It is the interim goal of my administration to achieve no overall net loss in acreage and function of Washington’s remaining wetland base. It is further the long-term goal to increase the quantity and quality of Washington’s wetlands resource base.” 14.0 Mitigation & Mitigation Sequencing A variance to the buffer requirement will require use of mitigation sequencing and mitigation for buffer impacts. Mitigation will comply with the applicable order sequence requirements for mitigation sequencing. Incompliance with mitigation sequencing, the project will avoid all direct critical area impacts and provide mitigation for unavoidable buffer impacts. Onsite rehabilitation of buffers may provide mitigation for buffer impacts. The remaining critical areas and their buffers will be protected in permanent tracts that will be maintained and monitored according to the approved Restoration Plan. 3 4 15.0 Authority and Statement of Accuracy This wetland determination is in accordance with Section 404 of the Clean Water Act. The critical area determination, delineation and ratings are accurate to the best of the Professional Wetland Scientists ability and knowledge. No assumptions were made for the work performed. 16.0 Limitations Stream and wetland determinations and delineations are not final until approved by regulatory agencies and/or local jurisdictions. J. S. Jones and Associates, Inc. does not guarantee acceptance or approval by regulatory agencies, or that any intended use can be achieved. 17.0 Summary Wetland A occupies a portion of the subject tax parcels. Wetland A is a Category II wetland with a 150 foot buffer requirement. Honey Creek and a tributary of Honey Creek flow through Wetland A. Honey Creek and the tributary to Honey Creek are Type Ns streams with a 50-ft buffer requirement. No direct impacts to wetlands or streams are proposed. Buffer impacts are unavoidable. Buffer impacts will be mitigation onsite according to mitigation sequencing and an approved mitigation plan. No priority habitats or species will be impacted. Critical areas and their buffers will be protected by placing them in either a native growth protection easement or critical area tract. 18.0 References COE. 2010.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fish and wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to variation caused by disturbance, changes in season and weather, and other factors.
