(WRI) conducted a site investigation on February 23, 2022, at the property located at 8311 Talbot Road, in Edmonds, Washington to identify and evaluate jurisdictional wetlands and fish and wildlife habitat conservation areas on and near the site. The 0.46-acre parcel (parcel #00594400001301) is further identified as a portion of Section 7, Township 27N, Range 04E, W.M. It is located within the Puget Sound drainage sub -basin of the Cedar- Sammamish Watershed, Water Resources Inventory Area (WRIA) 8. As part of the permit review process, the City of Edmonds requires a wetland and stream evaluation for the proposed development. Two wetlands were previously identified in the vicinity of the subject property, and Perrinville Creek is located off -site to the northeast. 2.0 SITE DESCRIPTION The subject property is developed with a single-family residence. The remainder of the property consists of maintained lawn and landscaping. Surrounding land use is single-family residential. Puget Sound is located to the north of the property. Topography of the site slopes gently to the north. Plant species observed within the lawn include unidentified maintained grass species, shotweed (Cardamine hirsuta; FACq, and white clover (Trifolium repens; FAC). Other species present on the property include western red cedar (Thuja plicata; FAC), birch (Betula sp.), ornamental rhododendrons, arbor vitae (7Thuja sp.), hellebores (Helloborus spp.), Japanese maple (Acer spp.), laurel (Prunus laurocerasus), and other ornamental species. No wetlands or streams were identified on the subject property. 8311 Talbot Road 1 Wetland & Stream Determination Report WRI #22027 March 3, 2022 Figure 1 - Aerial view of subject property (Not to scale) 3.0 REVIEW OF PUBLICLY AVAILABLE DATA Prior to conducting the site investigation, 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 included the following: USDA/MRCS Web Soil Survey The southern part of the property is mapped as Alderwood-Urban land complex, 8 to 15 percent slopes. This soil map unit is described as moderately well drained and contains inclusions of Norma soils (5 percent), which is a hydric soil that typically occurs in drainageways. The northernmost part of the property is mapped as Alderwood-Urban land complex, 2 to 8 percent slopes. This soil map unit is also described as moderately well drained. It contains inclusions of Norma (5 percent), McKenna (5 percent), and Terric Medisaprists (5 percent), which are hydric soils typically occurring in depressions. 8311 Talbot Road 2 Wetland & Stream Determination Report WRI #22027 March 3, 2022 Ci y of Edmonds GIS Interactive Map The City of Edmonds GIS interactive online map displays a large wetland unit extending onto the northern and easternmost portions of the property. Perrinville Creek is shown approximately 60 feet east of the northern part of the property. The limit of the 100-year floodplain is mapped approximately 15 feet north of the property. Snohomish County PDS Map Portal PDS Map Portal depicts the limits of the 100-year floodplain and Perrinville Creek in the same location as shown on the Edmonds GIS interactive map. This resource also maps Cutthroat Trout and Coho salmon in the western part of the site apparently in the location of the sewer easement. However, no stream channel is mapped on the property and no channel was observed on site. USFWS National Wetlands Inventory (JVWI) NWI depicts a Riverine, Intermittent, Streambed, Seasonally Flooded (R4SBC) feature in the same location as the salmonid presence mapped by Snohomish County PDS Map Portal. WA DNR Wetlands of High Conservation Value Interactive Map This resource does not depict any features on or near the subject property. WA DNR Forest Practices Application Mapping Tool (FPAM7) This resource depicts a Type F stream in the same location as the feature mapped by NWI. WDFW SalmonScape Interactive Mapping System SalmonScape shows documented presence of Resident Coastal Cutthroat Trout and Coho salmon in the same location as the feature depicted by NWI and FPAMT. WDFW Priority Habitat and Species (PHS) Interactive Map PHS show occurrence of Coastal Cutthroat Trout and Coho salmon in the same location as the feature depicted by NWI and FPAMT. 4.0 METHODOLOGY 4.1 ORDINARY HIGH WATER MARK DETERMINATION METHODOLOGY The ordinary high water mark (OHWM) of streams was determined using the methodology described in the Washington State Department of Ecology document Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Anderson et. al. 2016). 4.2 WETLAND DETERMINATION METHODOLOGY Wetland boundaries were determined using the routine approach described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region 8311 Talbot Road 3 Wetland & Stream Determination Report WRI #22027 March 3, 2022 (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 4.2.1 Hydrophytic Vegetation Criteria The Corps Manual and 2010 Regional Supplement define hydrophytic vegetation as "the assemblage of macrophytes that occurs in areas where inundation or soil saturation is either permanent or of sufficient frequency and duration to influence plant occurrence." Field indicators are used to determine whether the hydrophytic vegetation criteria have been met. Examples of these indicators include, but are not limited to, the rapid test for hydrophytic vegetation, a dominance test result of greater than 50%, and/or a prevalence index score less than or equal to 3.0. 4.2.2 Soils Criteria The 2010 Regional Supplement (per the National Technical Committee for Hydric Soils) defines hydric soils as soils "that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part." Field indicators are used to determine whether a given soil meets the definition for hydric soils. Indicators are numerous and include, but are not limited to, presence of a histosol or histic epipedon, a sandy gleyed matrix, depleted matrix, and redoximorphic depressions. 4.2.3 Hydrology Criteria The 2010 Regional Supplement defines wetland hydrology as "areas that are inundated (flooded or ponded) or the water table is less than or equal to 12 inches below the soil surface for 14 or more consecutive days during the growing season at a minimum frequency of 5 years in 10." During the early growing season, wetland hydrology determinations are made based on physical observation of surface water, a high water table, or saturation in the upper 12 inches. Outside of the early growing season, wetland hydrology determinations are made based on physical evidence of recent inundation or saturation (i.e. water marks, surface soil cracks, water -stained leaves). 5.0 RESULTS No wetlands or streams were identified on the subject property. Soils near the northern property boundary are very dark brown (7.5YR 2.5/2) silty clay loam in the upper 2-3 inches and very dark grayish brown (2.5Y 3/2) sand to a depth of at least 16 inches. Soils were moist throughout the observed profile at the time of the site investigation. On -site vegetation and soils are not indicative of prolonged saturation and no wetland hydrology indicators were observed. 8311 Talbot Road 4 Wetland & Stream Determination Report WRI #22027 March 3, 2022 Figure 2 -Site conditions. Top: facing west. Bottom: facing east. The two off -site wetlands were rated under the Washington State Wetland Rating System for Western Washington (Hruby 2014). Because these wetlands are located off -site on private property and WRI does not have legal access, the assessment was conducted using aerial photographs, topographic contours, and reference to the previously conducted studies. When measures to minimize impacts to wetlands are applied, buffers are determined under Edmonds Community Development Code (ECDC) 23.50.040(1�(1)(e). When these measures are not applied, buffers are determined under ECDC 23.50.040(1�(l (g). 8311 Talbot Road 5 Wetland & Stream Determination Report WRI #22027 March 3, 2022 5.1.1 Wetland A (off site) Cowardin Classification: Palustrine, Scrub -shrub Wetland, Broad-leaved evergreen, Seasonally Flooded HGM Rating Classification: Depressional DOE Rating Score: 17 (Habitat Score 6) DOE Rating Classification: Category III City of Edmonds Buffer: 110 feet (with mitigation measures) or 150 feet (without mitigation measures) Wetland A is located off site to the northwest and was identified in a previous study (Wetland Determination and Enhancement, Felton Residence; Skillings Connolly, Inc., dated December 1, 2014). This wetland has both slope and depressional characteristics. Therefore, it was rated using the Depressional rating form. This wetland includes scrub -shrub and emergent vegetation classes. Wetland A receives a total of 17 points on the wetland rating form (6 points for water quality, 5 points for hydrologic function, and 6 points for habitat function). This results in a Category III classification. Pursuant to ECDC 23.50.040, Category III wetlands with a habitat score of 6 receive a 110-foot protective buffer when measures to minimize impacts are applied. When these measures are not applied, a 150-foot protective buffer is required. 5.1.2 Wetland B (off site) Cowardin Classification: Palustrine, Scrub -shrub Wetland, Broad-leaved evergreen, Seasonally Flooded HGM Rating Classification: Riverine DOE Rating Score: 19 (Habitat Score 6) DOE Rating Classification: Category III City of Edmonds Buffer: 110 feet (with mitigation measures) or 150 feet (without mitigation measures) Wetland B is a small, riverine wetland associated with Perrinville Creek. This wetland was identified in a previous study (Critical Areas Report and Mitigation Plan: Talbot Road — Perrinville Creek Drainage Improvement; Herrera Environmental Consultants, Inc., dated April 15, 2010). It is located at the culvert where the stream flows beneath the BNSF railroad. Vegetation within Wetland B consists of scrub -shrub vegetation. Wetland B receives a total of 19 points on the wetland rating form (7 points for water quality, 6 points for hydrologic function, and 6 points for habitat function). This results in a Category III classification. Pursuant to ECDC 23.50.040, Category III wetlands with a habitat score of 6 receive a 110-foot protective buffer when measures to minimize impacts are applied. When these measures are not applied, a 150-foot protective buffer is required. 8311 Talbot Road 6 Wetland & Stream Determination Report WRI #22027 March 3, 2022 5.1.3 Perrinville Creek Cowardin Classification: Riverine, Upper Perennial, Streambed, Sand City of Edmonds Classification: Type F City of Edmonds Buffer: 100 Perrinville Creek is located approximately 55 feet northeast of the subject property. Perrinville Creek is an anadromous fish bearing stream and the reach that is near the subject site has anadromous fish access. Therefore, this stream reach requires a 100-foot buffer. 6.0 PROJECT DESCRIPTION The applicant is proposing to remove an existing concrete walkway, replace an existing deck and patio, and add new stairs. All project work will take place outside of critical areas and buffers. Therefore, no critical area impacts will occur. 8311 Talbot Road 7 Wetland & Stream Determination Report WRI #22027 March 3, 2022 7.0 USE OF THIS REPORT This report is based largely on readily observable conditions and, to a lesser extent, on readily ascertainable conditions.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 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 Ifyour 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 Ifyour 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. NO-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). 5. 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 Go to First Page 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-goto7 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-goto8 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 0 Riverine Slope + Depressional 0✓ De ressional Slope + Lake Fringe 0 Lake Fringe Depressional + Riverine along stream within boundary of depression 0 Depressional Depressional + Lake Fringe 0 Depressional Riverine + Lake Fringe 0 Riverine Salt Water Tidal Fringe and any other class of freshwater wetland 0 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 "a tang.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 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 Ifyour 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 Ifyour 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. NO-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). 5. 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 B NO - go to 6 IYES - 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-goto7 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. 1►[��3i%Ti�.I 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.
