OF Ronald Hadley and Nathan Munn Wetland Delineation Report Lake Leland Quilcene WA January 2002 Introduction At the request of Ronald Hadley, a wetland delineation was conducted by Dixie Llewellin of Olympic Wetland Resources, Inc. on the Lake Leland property owned by Nathan Munn. The subject property consists of 10.14 acres on the southwest end of Lake Leland. The purpose of the delineation was to classify the wetland, establish the wetland edge, and define associated buffers. Fieldwork was conducted on December 27, 2001. Wetlands associated with Lake Leland are shown on the Critical Areas Map (Eastern Jefferson County, February 21, 1995). Two Type 5 streams are included on the map and were confirmed during this site assessment. All wetlands within Jefferson County are subject to requirements outlined in the Jefferson County Unified Development Code dated January 1, 2001. Land use restrictions will apply to all future development projects associated with this parcel. Description of Site · Description: Parcel # 80226410 (Appendix Map #1: Location Map) · Location: Approximately 4 miles north of Quilcene off 101, Leland Valley Road to Leland cutoffroad, gravel road on right · Soils: Belfast silt loam, heavy variant (Bh), Swantown gravelly sandy loam (StB), And Wapato silty clay loam (Wa) (Appendix Map #1: Soils) · Slopes: Bh 1-2%, StB 0-8%, Wa 0-3% (steeper slopes observed) The property slopes downward to wetlands associated with the southwest end of Lake Leland. Two streams flow through the property on moderate to steep slopes, spreading out in a flat low lying swale and terminating in Lake Leland. The majority of the property is forested: Douglas' fir, hemlocks, and maples on the hillside changing to cedar~_r_=al_der and spruce inthedownslopeareas. ![~) [~ [~ ['~ ~ ~/ lf~ 115,~ JEFFERSON COUNTY DEPT. OF COMMUNITY DEVELOPMENT Hadley/Murm Delineation Report Report File Number 2002-0074 Lake Leland Ol.~xnpic Wetland Resources; Inc. 1/02 Applied Methodology The following resources were consulted for this project: · Jefferson County Critical Areas Map Wetlands (1995) and ESA Maps (Stream and Wetlands) · Jefferson County Unified Development Code (January 1, 2001) · Soil Survey of Jefferson County (U.S. Soil Conservation Service 1975) · National Wetland Inventory Map · Washington State Wetland Identification and Delineation Manual · National List of Plant Species that occur in Wetlands: Northwest (Region 9) Classification Wetland categorization was determined using the Washin~on State Department of Ecology (DOE) Wetland Rating System (publication ~91-57 October 1991), which assigns a numerical value to any given wetland according to wetland size, quality of surrounding buffers, vegetation diversity, wetland types, and habitat value. Wetlands are rated as entire systems and quite often exceed project boundaries. Washington State Wetland Identification and Delineation Manual Fieldwork to determine the actual wetland boundaries was conducted according to the methodology outlined in the Washington State Wetland Identification and Delineation Manual (Department of Ecology #96-94). Chapter 173-22 of the Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. The methodology outlined in the Washington State Wetland Identification and Delineation Manual requires examination of the three parameters for a positive wetland determination: hydric soils, hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictional wetland k must have a positive indicator from all three parameters. Ail wetlands identified using this methodology may be federally regulated, regardless of size. A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer. Hydric soils favor the growth and regeneration ofhydrophytic vegetation. The indicators for this type of soil include low chroma~ mottles, ~eying, and high organic content within the upper 32 inches of the soil profile. Holes were dug on the site and soil colors (including value and chroma) were recorded in the top 16 inches. Soil colors were analyzed using the Munsell Color Charts (1992). The Jefferson County Soil Survey map, indicating soils found on subject property, is included in the Appendix (Map # 1). Vegetatl'on Wetland plant species must constitute greater than 51% of the total vegetation pre qualification as a site dominated by hydrophytic vegetation. Dominance of plant si Hadlev/Munn Delineation Report Report File Number 2002-0074 2 ;ent to meet the ..~ .J~FF~SON COUNi¥ D~~ U~I~ DEV~LOP~NT O1)mpic Wefl~d Res ~'~-1-/~2~~ determined by calculating actual aerial cover within a 3 O-foot radius for trees, a 1 O-foot radius for shrubs, and a 6-foot radius for the herbaceous layer at each data point. Commonly occurring plant species have been rated by the United States Fish and Wildlife Service (USFW) National List of Plant Species That Occur in Wetlands: Northwest (Re¢on 9), as to their fi-equency of occurrence in wetlands and non-wetlands. During the fieldwork, each species was recorded and given a rating based on indicator status. tIydrology Wetland hydrology is defined in the Washin~on State Wetland Identification and Delineation Manual as "areas that are periodically inundated or have soils saturated to the surface at some time during the growing season". Areas must have seasonally inundated or saturated soil at least 12.5% of the growing season. Indicators of hydrology include visual observation of inundation or soil saturation, water-stained leaves, cracking of the soil surface, and/or sediment deposits. Positive signs of hydrology are often absent during the summer and fall months but can be inferred if there are positive indicators ofhydric soil and hydrophytic vegetation. Determining PVetland Edges Wetland edges were determined by establishing a data point within the wetland, which contained positive indicators of all three of the wetland requirements: soils, hydrology, and vegetation, and another data point outside the wetland, where one or all of the requirements were not present. Measurements were taken with a Chainman II hip chain from a recent survey point along the northern property boundary. Findings Two Type 5 streams were confirmed; running water was observed in both perennial streams during the December site assessment. Type 5 streams have an associated 50-foot buffer (100'total). According to the UDC standard, Streamside buffers are applied to each side of the stream (Section 3-25 5v. and Table 3-2). Exact steam location as it falls on the property should be confirmed by a field survey. Topography, vegetation cover, and soils consistently define the wetland edge. In general, the wetland lies at the toe of the slope where the land flattens out. The partial source of hydrology for the wetland is water from the streams fanning out before entering Lake Leland. The eastern third of the property, which is below the access road, consists of jurisdictional wetlands and associated buffers. Hadley/Munn Delineation Report Report File Number 2002-0074 The wetland edge was flagged with orange plastic ribbon labeled "Wetland Boundary"' (at points marked A1 through A11) and was tied to vegetation at eye level along the wetland edge at spacing of 20 to 40 feet, depending on visibility. All data points were marked and labeled with green flagging. A survey was being conducted on the parcel to the north the same day as this delineation. All measurements on the northern border were measured from a recent survey point. Due to the density of vegetation and lack of other exact survey [I ~ l [~ [[.J ~;1 tl ¥? .......................OCT 28 2002 3 Lakd~f~¢itl; 0 N COUNTY Ol?npic Wetland R--.z~¢?e¢[n~ O[¢(~:~LINITY~. . DEVELOP¥,EN'r points are approximate and should be confirmed by a survey if development takes place within 10 feet of the buffer. All data points, flagging points, wetland edges, and buffers for streams and wetlands are indicated on the Findings Map (Appendix Map #2). Classification A high quality Class II (38 points) wetland was identified on site. A copy of the Department of Ecology wetland rating form is included at the end of this report. This wetland extends off site to the north and south and was possibly much large prior to surrounding development. According to the Jefferson County UDC, Class II wetlands have a protective 100-foot buffer surrounding the actual wetland edge (Table 3-4 Standard Buffer Widths for Wetlands). Buffer distances are measured at right angles fi-om the flagged wetland edges. According to the Jefferson County Soil Survey the following soils are mapped on site: Belfast silt loam, heavy variant (Bh), Swantown gravelly sandy loam (StB), and Wapato silty clay loam (Wa). Wapato is classified as a hydric soil on the Jefferson County Area Hydric Soil list (January 1991). Soil pits confirmed the presence ofhydric soils. Ihese soils are dark brown and often had bright orange mottles, which form in soils that are regularly saturated. Data points #1., #2, and g4 were observed with these characteristics (10YR 3/1 silty clay loam and 10YR 4/1 mottles present 10YR 5/6). At Data Point #3 and #5 soil colors changed and mottles were less frequent or not present (10YR 4/2 no mottles). Other soil test pits were dug to confirm the location of the wetland edge. Vegetation Although most vegetation was dormant during the December delineation, the majority of the trees and shrubs could be identified by branch and twig characteristics. Several herbaceous plants were identified by plant material from last season's growth and early new growth due to the mild winter. Hydrophytic vegetation was identified throughout the eastern portion of the property. The forest cover in the wetland consisted of cedars, spruce, and alders with a thick understory, which was predominately salmonberry. In the herbaceous layer the water- tolerant plants identified include water parsley, horsetail, buttercup, piggyback plant, and slough sedge. A transition area with less water-tolerant vegetation defines the wetland/upland edge. This area contains Douglas fir, vine maple, bigleafmaple, ocean-spray, snowberry, and sword fern. Salmonberry is found in both the wetland and upland edge since it can tolerate a range of soil conditions. Both the big-leaf maple and vine maple are often seen near the wetland edge but prefer drier soils conditions. Physiological adaptations, such as sword ferns growing on hummocks of soil or stumps, were observed in this wetland. When the vegetation is in question a wetland edge is confirmed by the findings in the soil test pits. Table 1 presents a partial listing of the vegetation identified on the property.

The ~owing season is defined by the Jefferson County soil survey as March 12 to November 25. Hydrology must be present for 12.5% (20 days) of these 258 days. The growing season is defined by soil temperature at 19.7 inches below the soil surface to be higher than biological 0 (5° C, or 40° F). Although this delineation took place three weeks after the official end of the growing season, soil temperatures at 20" down were still above 40° F (41.4°). Surface and ponded water was present in several locations and saturation was present in all pits dug within the wetland. At the steam outlets, water was flowing and soils were heavily saturated.

This high quality forested wetland is well defined by topography, vegetation, hydric soil characteristics, and the presence of hydrology. Two Type 5 Streams cross the subject property from west to east and have buffer requirements of 50 feet, measured on either side of the stream (100'total), to further restrict the buildable area. Buffer widths can be altered or reduced for both stream and wetlands under certain conditions outlined in the UDC (Section Streams 3 3-25 (6), and Wetlands 3-30 (6) Reducing Buffer Widths). The staff of the Jefferson County Department Of Community Development must approve all plans for alterations. The applicant must demonstrate that there is no adverse effect to the wetland, stream, or function of buffers and that disturbance to native vegetation will be minimal. A Habitat Management Plan is required for all stream related buffer reductions and a buffer enhancement plan may also be required. Under no circumstance will buffers be reduced by more than 25%. A copy of this report has also been prepared for submittal to Jefferson County Department Of Community Development. If there are further question or planning requirement for this projects please do not hesitate to call. Sincerely, Dixie Llewellin Principal Biologist, Olympic Wetland Resources, Inc.
