Suite 106 Everett, Washington 98208 (425) 337-3174 Fax (425) 337-3045 RE: Wetland Determination Report for Snohomish County Tax Parcel 27043200200100 Wetland Resources, Inc. (WRI) performed site visits on August 22, 2017 and September 5, 2017 in order to locate and evaluate jurisdictional wetlands on and in the vicinity of the .5-acre site located at 23511 74th Ave W. The subject property is located along the western shoreline of Lake Ballinger in the city of Edmonds, WA. Access is from the north via 74th Ave W. The site is further located as a portion of Section 32, Township 27N, Range 4E, W.M. The subject property contains a single-family residence (SFR) and associated residential improvements. Surrounding land use is primarily high intensity residential (> 1 unit/acre), shoreline and a public park. The property is bound to the west by 74th Ave W, to the north and south by SFRs and to the east by Lake Ballinger. Lake Ballinger is considered a Shoreline of the state due to its large physical size (>20 acres). Landward of the ordinary high water mark (OHWM) is designated as Shoreline Residential III, while waterward of the OHWM is designated as Aquatic I. Vegetation within the subject property consists primarily of maintained lawn to the OHWM with patches of red -twig dogwood and cattail along the edge of the lake. Extending out into the lake, vegetation transitions to yellow water lily. Topography of the site is a moderate east aspect slope on the western portion of the site, flattening to a slight east aspect along the eastern portion of the site. An existing sewer line crosses the eastern portion of the lawn in a north south orientation. On -site soils in the non -wetland portion of the site are historic fill (likely from interurban railroad, house construction, or sewer line installation) throughout much of the yard. From 0 to 16 inches below, these soils are 2.5Y 4/3 with no redoximorphic features. From 16 to greater than 18 inches, the soils change to 2.5Y 2.5/1. All soils within the non -wetland portion of the site were dry at the time of inspection. Soils within the wetland portion of the site were 2.5Y 2.5/ 1 from 0 to 18 inches below. These soils were moist to saturated at the time of investigation. METHODOLOGY AND RESULTS Prior to conducting the site investigations, public resource information was reviewed to gather background information on the subject property and the surrounding area in regards to wetlands, streams, and other critical areas. These sources include: the USFWS National Wetlands Inventory (NWI), WDFW SalmonScape Interactive Map, WDFW Priority Habitat and Species (PHS) Interactive Map, and the City of Edmonds online GIS Tool. Wetland Determination Report 1 WRI # 17009 Duf 70 Ave W September 21, 2017 Wetland areas were determined using the routine determination approach described in the Corps of EE,,ineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (U.S. Army Corps of Engineers 2010). Under the routine methodology, the process for making a wetland determination is based on three steps: 1) Examination of the site for hydrophytic vegetation (species present and percent cover); 2) Examination of the site for hydric soils; 3) Determining the presence of wetland hydrology. BOUNDARY DETERMINATION FINDINGS/RESULTS Wetlands were rated pursuant to the Washington State Wetland Rating System for Western Washington (Hruby 2014), as required by Edmonds Municipal Code. Wetlands were also classified according to the U.S. Fish and Wildlife Service (USFWS) Classifications of Wetlands and Deepwater Habitats of the United States (Cowardin et al., 1979), also known as the Cowardin Classification System. One lake fringe wetland was delineated on the eastern portion of the site immediately adjacent to the lake. This boundary is clearly defined by topography and the boundary of the historic fill and is similarly depicted on the City of Edmonds on-line GIS and the National Wetland Inventory. The wetland unit, as depicted on the attached map, was rated utilizing the Washington State Wetland Rating System for Western Washington, 2014 as a Category III with a low habitat score. Per EDMC 24.04.020, Category III wetlands with low habitat scores located within shoreline jurisdiction are designated 60- foot protective buffers from their delineated boundary. PROPOSED DEVELOPMENT ACTIVITY A garage addition is proposed on the western side of the existing SIR, approximately 175 feet away from the wetland and well outside of the designated 60-foot buffer. In addition, the proposed garage will be constructed on existing impervious surface with landscaping. No impact to Lake Ballinger, the on -site lake fringe wetland, or its associated buffer will occur as part of this development activity. The applicant also wants to resolve the existing violation (case #COD2017-0068) related to minor grading activities within the mowed lawn portion of the site in the vicinity of the lake and lake fringe wetland. Based on the WRI delineation, the grading occurred well outside of the wetland boundary, but partially within the designated 60-foot buffer. This area has already been re -contoured to match the assumed pre-existing grade (based on adjacent elevations). WRI recommends that this area be further restored by grass seeding to a seed mixture similar to the existing on- and off -site lawn conditions. This will restore the pre-existing function of the buffer and allowed continued use of the lawn. The purpose of this report is to provide a preliminary reporting of on -site critical areas for the purposes of assisting in the pre -application process for a proposed development activity. As part of the formal building permit process, a Critical Area Report that meets the requirements of EDMC 23.40.090 and 23.50.030 will be prepared and submitted to the City of Edmonds for review. Wetland Determination Report 2 WRI # 17009 Dufy 74th Ave W September 21, 2017 USE OF THIS REPORT This Wetland Determination Report is supplied to Brian Duffy and Nancy Lindstrom as a means of determining the presence of on -site and adjacent critical areas, as required by the City of Edmonds. This report is based largely on readily observable conditions and, to a lesser extent, on readily ascertainable conditions. No attempt has been made to determine hidden or concealed conditions. The laws applicable to critical areas are subject to varying interpretations and may be changed at any time by the courts or legislative bodies. This report is intended to provide information deemed relevant in the applicant's attempt to comply with the laws now in effect. This report conforms to the standard of care employed by wetland ecologists. No other representation or warranty is made concerning the work or this report and any implied representation or warranty is disclaimed. Wetland Resources, Inc.

NO - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. 0-goto5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). Does the entire wetland unit meet all of the following criteria? `The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number A NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 1 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional F7 Depressional Slope + Lake Fringe 0 La e Frin e Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe [] Depressional Riverine + Lake Fringe 0 Riverine Salt Water Tidal Fringe and any other class of freshwater wetland E] Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the racing.
