Felton Wetland Determination Skillings Connolly Inc. rqm 5016 Lacey, Blvd Lacey, WA 98503 December 19, 2014 Project # 14115 Sam & Lin Felton 8415 Talbot Rd, Edmonds, WA 98026 RE: Wetland Determination and Enhancement, Felton Residence SITE LOCATION A site visit of the Felton property located within Township 27N, Range 4E, Section 7 at address 8415 Talbot Rd, WA 98026, was conducted on November 18, 2014. The property consists of two lots identified as parcel #0059440001600 and #0059440001500. The Felton residence located on parcel #0059440001600 is situated on the western side of the lot closest to Talbot Rd. The adjacent lot to the east is undeveloped. The area of Wetland A delineation which lies at the north end spans the lower portion of both lots adjacent to the railroad tracks (Figure 1). The property is located in Snohomish County, Washington in the City of Edmonds (Exhibit 1, Site Map). The area is considered high intensity land use. The site visit was conducted to determine the extent and classification of Wetland A, identified on the Property. METHODOLOGY The wetland delineation performed is in accordance with The City of Edmonds Code 23.50.010 designation, rating and mapping —Wetlands, Designating Wetlands and the Army Corp of Engineers Wetland guidelines for wetland delineation and Department of Ecology's (DOE) Wetland Rating Form for Western Washington (Hruby, 2004). Wetlands are those areas, designated in accordance with the Washington State Wetland Identification and Delineation Manual (1997), that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and Figure 1. Wetland A approximate location, see Exhibit 2 for details. Felton Wetland Determination that under normal circumstances do support, a prevalence of vegetation adapted for life in saturated soil conditions. All areas within the city of Edmonds meeting the wetland designation criteria in the Identification and Delineation Manual, regardless of any formal identification, are hereby designated critical areas and are subject to the provisions of this title. SITE CONDITIONS The site is located in a densely populated residential area within the City of Edmonds. Wetland A, located on the north end of the Felton property has been aggressively pruned. Downed woody debris covered in moss was observed along with willow cuttings from pruning activity. Initial observations of hydrologic functions include pooling water throughout Wetland A. Upland vegetation situated south of the wetland mainly consisted of cedar and maple. The rail road borders the northern boundary of the property and sits atop an embankment. The embankment was overrun by invasive Pacific Trailing Blackberry which was pruned along with vegetation within the wetland. The east and west boundaries of the property incorporate a rustic trail which accesses the shoreline and are divided by a fence to the east and a retention wall to the west, separating property boundaries. North of the rail line on the other side of the embankment is designated shoreline. Hydrology: Wetland A is located on the north end situated in a depresional landscape, spanning both properties (Figure 1 & Exhibit 1). Wetland A receives most of its hydrology from sheet flow, permeation and high levels of groundwater. Wetland A takes the form of Depressional/Slope according to the 2014 Wetland Rating Form for Washington State (Exhibit 2, 2014 - Wetland Rating Form). Water enters Wetland A via sheet flow, ground water penetration and existing water table levels from the north, west and south sides. Once water settles within the depression, slow flows from the west towards the east portion of the wetland occur due to a gradual 1-2% slope, depressional pockets retain water causing shallow pooling, eventually draining by way of ground penetration. The north side of Wetland A has a steep man made slope that falls within the easement belonging to the rail road. The embankment consists of a 159/c slope which spans the distance of the property boundaries to the east and west. There is no obvious outlet; areas within the wetland indicated in Exhibit 1 tend to be inundated for longer periods of time when precipitation levels are consistent to high. The north boundary, while contained by the rail embankment could experience groundwater influences from tidal fluctuations from the shoreline directly located on the northern side of the railway embankment. Additional water testing for salinity levels would need to be conducted to determine this event. The southern border of Wetland A is fed by sheet flow and ground water penetration, slope conditions range from 8-15%. The Felton properties are located in an area where sheet flow from Talbot Road will influence drainage of water to and through the property. Soils: The Natural Resource Conservation Service (NRCS) Web Soil Survey indicates that the Property is in an area that consists primarily of Alderwood-Urban land complex on slopes ranging from 2-15% (Exhibit 4). This soil type is not considered hydric in the Hydric Soils List for Snohomish County (USDA 2001). 5 Skillings Connolly, Inc. (360) 491-3399 21 P a g e Felton Wetland Determination Vegetation: Wetland A is dominated by plants that typify freshwater wetlands. The upland areas surrounding Wetland A was characterized by a vegetative community dominated by sword fern (Polystichum munitum), cedar, big leaf maple (Alnus rubra) and Douglas fir (Pseudotsuga menziesii). RESULTS Based on observations of wetland hydrology, hydric soils, and a dominance of wetland plant species (hydrophytes), it can be concluded that a slope wetland (Figure 1, Wetland A) is located on the north end of both Properties. Wetland A is a small regulated slope wetland which spans from both property boundaries. Wetland A was categorized as type III. Category III wetlands are wetlands with a moderate level of functions as indicated by a score of <30 points on the city of Edmonds wetland field rating form (Wetland Rating Form —western Washington version 2, Ecology Publication 04-06-025, August 2004). Two 18 inch -deep soil pits were excavated within Wetland A (Soil pits 1 and 5, Table 1 & 5 and Exhibit 5) to analyze and describe soil and hydrology conditions within the wetland. Soils within the wetland were saturated to the surface at both soil pits. The soils in Wetland A are either silt loam or silty sand. The following breakdown describes soils types which were rated in the field using the 2009 Munsell Soil Color Guide. Table 1.

Three soil pits were excavated to a depth of 18 inches just outside of Wetland A in order to determine boundaries and upland soil and hydrology characteristics. Soil saturation was not observed in either pit. The following breakdown describes soils types which were rated in the field using the 2009 Munsell Soil Color Book: Table 3.

Diversity among plant species fell within the 5-19 species range based on field observations but could be higher once plants have a chance to grow back. The following tables quantify plants within and around Wetland A and are broken out by soil pit locations (Figure 2): Table 6. Wetland A.

Each site was selected to determine soil types, hydrologic conditions and vegetation in the surrounding area of each site. Identified above in Tables 1 and 5, soil pits 1 and 5; it was observed that these areas were within the wetland and contained all three wetland indicators; hydric soils, hydrology and vegetation. Soil pits 2, 3 and 4 (Table 2, 3 and 4) fell just outside the boundaries and clearly showed non hydric soils with characteristics of upland vegetation and hydrologic function. Since the wetland provides a lower level of functions (Category III, see Exhibit 2) and has a habitat score of 38 points, it is considered a Class III 5 Skillings Connolly, Inc. (360) 491-3399 5 1 P a g e Felton Wetland Determination wetland. The City of Edmonds County Code 23.50.030 was referenced to determine buffers and mitigation measures. The City of Edmonds Critical Area Ordinance (CAO) requires a buffer setback for all regulated wetlands (23.50.040 Development standards - Wetlands). In High Intensity Land Use areas, class III wetlands (Wetland A) require a 50 foot buffer (Exhibit 2) around the entire wetland (23.50.040 F. Wetland Buffers). Based on field observations for plant species within Wetland A, 17 plant types were identified and were classified under tree, scrub -shrub and herbal varieties (Table 6, Wetland A Plant Types). While Wetland A has undergone pruning by the homeowner, impacts to the wetland will not deter existing vegetation from growing back in full form. Future maintenance for the wetland would include removal of invasive species and elimination of future pruning of wetland vegetation. In order to enhance the wetland, planting within the wetland and in the 50 foot buffer would benefit from scrub -shrub varieties (Table 7). Scrub -shrub varieties include Salal (Gaultheria shallon), Red Osier Dogwood (Cornus Sericia), Snowberry (Symphoricarpos), Black Twinberry (Lonciera Involucrate), and Sword Fern (polystichum Munitum). Wetland functions, including water quality improvement and flood storage are based on the geomorphic shape of the wetland, which has not been altered, therefore water quality and flood storage functions have not been impacted. MITIGATION In order to restore value and function to Wetland A and to meet the minimal requirements Section 23.40.240 ECC was referenced. Unauthorized critical area alterations and enforcement, for the City of Edmonds states: "when a critical area or its buffer has been altered in violation of this title or the provisions of Chapter 7.200 ECC, all ongoing development work shall stop and the critical area shall be restored. Requirement for Restoration that meets best available science is describe below and will show how the actions proposed meet the minimum requirements described in subsection C Minimum Performance Standards for Restoration. City code states, for alterations to frequently flooded areas, wetlands, and fish and wildlife habitat conservation areas, the following minimum performance standards shall be met for the restoration of a critical area, provided, that if the violator can demonstrate that greater functional and habitat values can be obtained, these standards may be modified." Value and Functions: Wetlands A functions include water detention and filtration. Wetland A and its surrounding buffers maintain most if not all of its existing vegetation after pruning, roots structures were not compromised and signs of new growth were taking form. Aggressive pruning will not affect water quality functions but does impact areas for migrating birds and small animals. Minimal impacts related to the process of respiration will be altered until plants are able to grow to back. Over time as vegetation grows back plant respiration will improve as well as other wetland functions. Recommendations for the mitigation plan for vegetation within Wetland A and its buffers shall be replanted with native vegetation that replicates the vegetation historically found on the site in species types, sizes, and densities (Exhibit 2, Table 7). Historic functions and values should be replicated at the location of the alteration; Information demonstrating compliance with the requirements in ECDC 23.40.130, Mitigation plan requirements, will 5 Skillings Connolly, Inc. (360) 491-3399 6 1 P a g e Felton Wetland Determination be submitted to the city planning division. The total area to be planted is 4,430 square feet, of which falls within the 50' buffer (Exhibit 2). A small area falls outside of the property boundary which makes up the railway embankment. Since the pruning of vegetation occurred, this area is included in the planting plan. Table 7lists recommended vegetation and ratios for planting guidelines. Ratios are based off of the Army Corp of Engineers Mitigation Ratios for Western Washington. Category III wetlands require a 2:1 ratio for re-establishment. Table 7. Wetland & Buffer Planting Shrub Type — Scientific Name Count Red Osier Dogwood (Cornus sericia) (designated planting in wetland) 35 Planting 15' on center Snowberry (Symphoricarpos) 40 Planting 10' on center Western Sword Fern (Polystichum munitum) 50 Planting 4' on center Salal (Gaultheria shallon) 50 Maintenance: A critical component of maintenance is to manage invasive species. Currently the railroad embankment consists of trailing blackberry which has overrun all other species. Recent pruning did not result in the removal of this invasive species, and it is expected to grow back in the coming season. Even though the railroad embankment falls outside of the property boundaries removal of this invasive species is included in the mitigation plan. Planting guidelines are in accordance with the mitigation ratios set forth by the Army Corp of Engineers for re-establishment. The critical area and 50' surrounding buffer shall be replanted with native vegetation that replicates the vegetation historically found on the site in species types, sizes, and densities (Table 7). Establishment of new vegetation indicated in this report should aid in restoring the historic functions and values at the location of the alteration. Soils within Wetland A and its surrounding buffers were undisturbed. There were no signs of compaction by heavy equipment or excessive foot traffic. According to FEMA Flood maps Wetland A does not fall 5 Skillings Connolly, Inc. (360) 491-3399 7 1 P a g e Felton Wetland Determination within the 100 year flood plain and will not require additional alteration to improve flood storage. It's important to note that the Snohomish County Permit, Planning and Zoning Map does identify the surrounding area to include a portion of Wetland A as an area which is influenced by high tides, causing infrequent potential flooding to this area. In the case of a high tidal surge it is possible that wetland plants might be damaged or lost from longer than usual times of inundation. In this case the homeowners will have no control over plant survival. In addition Wetland A has a sewer line running east to west through the wetland. Any future maintenance or repair activities on this section of sewer line might jeopardize plant success and should be noted as a condition that falls outside of the responsibilities of the homeowner. Other contributing factors which might influence site hydrology and plant success are neighboring properties to the east which include residential development within the wetland buffers. Additional drainage from neighboring properties to Wetland A could add to higher water levels causing some plants to be inundated for longer periods not conducive for their survival. Monitoring: It is proposed that the Property owner be responsible for monitoring the proposed enhancement measures for a period of three (3) years. The Responsible Party will implement and abide by the proposed enhancement plan for the property. It is proposed that the Property owner will be responsible for any required contingencies if performance standards are not met. A Monitoring Report that includes a description of the site conditions, observed plant mortality, performance standard accomplishments, and recommendations, will be submitted to City of Edmonds during every year of monitoring. Performance Standards: Performance standards describe a desired state, threshold value, or amount of change necessary to indicate that a particular structure (or function) has been established (Washington State Department of Ecology 2006). Below are the Performance Standards that define success of proposed enhancement. 1) One hundred (100) percent of manually planted scrub -shrub species will survive by the end of each year during the monitoring period. 2) Within the buffer area, vegetative shrub cover will be at least fifty (50) percent by the second year and eighty (80) percent by the third year. 3) The percentage of area covered by invasive and non-native species (e.g. English ivy, Himalayan blackberry) will not exceed fifteen (15) percent within the enhancement area throughout the three year monitoring period. Contingencies: The Responsible Party (Property owner) will manage the establishment of plants from the first to the third year with the goal of meeting all applicable performance standards. If percent cover requirements for native herbaceous, native woody, and invasive vegetation are not satisfied, contingency activities may include, but are not limited to: ■ Plant replacement 5 Skillings Connolly, Inc. (360) 491-3399 8 1 P a g e Felton Wetland Determination ■ Plant supplement ■ Plant substitution ■ Adjustment of plant colonization technique ■ Adjustment of planting layout, reflecting specific or changing site conditions ■ Weed control Attempts would be made to limit the spread of invasive and exotic species. Noxious weed would be eliminated immediately if found occurring on the site, before large populations and additional seed banks become established. If more than fifteen (15) percent of the enhancement area is colonized by invasive or non-native species, the best method of eradication for the invasive species of concern would be implemented (e.g. hand pulling, mowing, and cardboard application).

Check List for Wetlands That May Need Additional Protection YES NO in addition to the protection recommended for its category) SP I. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are Cate orized as Category I Natural Heritage Wetlands (see p. 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW the for state? SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. 11 1� INA H Edro eomorphic Class of the wetland bein rated The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Weiland Rating Form — western Washington 2 August 2004 version 2 Updated with new WDFW definitions Oct. 2008 1, Wetland name or number -t 1. Arc water levels in the entire unit usually controlled by tides (i.e. except during floods)? 6- 0 —,go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) 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 rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and 11 estuarine wetlands have changed (see p. 2.
