The subject property is located between Flagler Road and East Marrowstone Road on Marrowstone Island. Since the property boundaries do not touch either road, access is through undeveloped easements. The purpose of the delineation was to fulfill the requirements defined by the Department of Community Development regarding potential on-site wetlands (letter from Jerry Smith dated June 28, 2001). Requirements include the location and field marking of all wetlands and determining wetland classification, thereby defining associated buffers. This project is subject to requirements outlined in the Jefferson County Unified Development Code dated January 1,2001. All land use restrictions will apply to thik project. Description of Site · Description: Parcel# 021-332-035 · Location: East of Flagler Road, West of East Marrowstone Road, North of Nordland Store on Marrowstone Island, WA Lot 1 Section 33 T30N, R1E, W.M. · Soils: Whidbey gravelly sandy loam (WhC) · Slopes: 0to 15% The 2-acre parcel gradually slopes downhill from east to west. The upper portion consists of a forest canopy with a mosaic of open meadows. The wetland generally lies in the lower northwest comer where there is a distinct vegetation change; the tree cover changes to willows and alders and there is a dense understory of wetland tolerant shrubs. A digital image of the wetland, a location map, the Jefferson County critical areas map, the Jefferson County soil survey map, and a wetland finding map are included in the Appendix. Methodology The following resources were consulted for this project: · Jefferson County Unified Development Code January 2001 · Jefferson County Critical Areas Map Wetlands (1995) · Soil Survey of Jefferson County (U.S. Soil Conservation Service 1975) · National Wetland Inventory Map Bergstrom Delineation Report Report File Number 2001-00524 Ol.x~npic Wetland Resources, Inc. 7/01 · 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 Washington 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 Washineton State Wetland Identification and Delineation Manual (Department of Ecology g96-94). 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: hydfic soils, hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive indicator from all three parameters. All 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, gleying, 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 # 3). Vegetation Wetland plant species must constitute greater than 51% of the total vegetation present to meet the qualification as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 30-foot radius for trees, a 10-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 frequency of occurrence in wetlands and non-wetlands. During the fieldwork, each species was recorded and given a rating based on indicator status. Hydrology 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 Bergstrom Delineation Report Report File Number 2001-00524 Ol.wnpic Wetland Resources, Inc. 7/01 1 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 il'there are positive indicators of hydhc soil and hydrophytic vegetation. Priority Habitats Washington Department ofFish and Wildlife: defines freshwater wetlands as priority habitats as defined below: Wetlands: Lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. Wetlands must have one or more of the following attributes: the land supports, at least periodically, predominantly hydrophytic plants; substrate is predominantly undrained hydric soils; and/or the substrate is nonsoil and is saturated with water or covered by shallow water at some time during the growing season of each year. Criteria: Comparatively high fish and wildlife density, high fish and wildlife species diversity, important fish and wildlife breeding habitat, important fish and wildlife seasonal ranges, limited availability, high vulnerability to habitat alteration. Detertnining Wetland Edges Approximate wetland edges were determined by establishing a data point within the wetland, which contained positive indicators of all three of the wetland requirements: soil's, hydrology, and vegetation, and another data point outside the wetland, where one or all of the requirements were not present. Orange wetland boundary flagging was placed at 100' intervals to define the wetland edge. All data points were marked and labeled with yellow flagging. Measurements were taken with a Chainman II hip chain from approximate property boundaries. A survey should follow the wetland delineation to determine the exact location of the wetland edge within the property boundaries. Buffer distances should be measured at angles perpendicular to the flagged wetland edges. Findings Findings from this report fulfill the requirements of a wetland delineation. Wetlands were identified in the lower northwest comer during the July site assessment. Standing water, wetland soil, and wetland plants were identified. Wetland edges were defined by topography, vegetation changes, and soil analysis. Wetlands were confirmed by data points and flagged in the field. This wetland is larger than 3 acres and is not indicated on the Jefferson Critical Areas Map. Wetland edges were flagged with orange wetland boundary flagging and all data points and soil test pits were marked with yellow/green flagging. A map of wetland locations, corresPonding data points, and flagging points is included in the Appendix (Map ~s4). Locations indicated on the 1 The growing season is defined by the Jefferson Count-,' soil survey as March 12 to November 25 in or near Port Townsend. HvdroloD' must be present tbr 12.5% (20 days) of these 258 days. Water in the tbrm of surface water, saturated soils, or standing water in the test pit is often absent during the dryer months (be~veen July and November). The growing season is defined by soil temperature at 19.7 inches below the soil surface to be higher than biological 0 (5° C, and'40° degrees F). This is often year-round in the lower areas of the Puget Sound. Bergstroin Delineation Report Report File Number 2001-00524 Ol.~.2npic Wetland Resources, Inc. 7/01 map are measured from fences on the property boundary (as described by Nell Bergstrom). Exact locations of wetland edges on the properly should be determined by a field survey. It should be noted that several wetlands in Jefferson County have receded during the last year due to reduced rainfall and therefore contain less surface water than usual during our wet season (personal observation: Strangers Lake, Tibals Lake, Froggy Bottoms). Annual rainfall was also far below normal for the year 2000 (13 inches instead of the average of 19 inches as recorded by Herb Herrington, official weather observer in Port Townsend). Water only needs to be present 20 days of the.growing season for an area to qualify as a wetland. Hydrology can be assumed when both positive indicators of wetland plants and wetland soils are present. Hydrology was not present at the data points during July but soils were moist or saturated. Wetland soils represent an historical indicator of the presence of water over an extended period of time, whereas plant communities can change as the water table fluctuates within 10 to 20 years. Even with the low rainfall, hydrology was observed in all of the wetlands identified on this site. Classification This wetland qualifies as a high quality Class II wetland (30 points) due to the presence of standing water, large size (extends off site), habitat features, high quality buffers, and species diversity. The buffer requirement for all Class II wetlands is 100 feet. Class II wetlands are regulated by the Jefferson County Critical Areas Ordinance if they are'larger than 10,000 i~2 (Section 6.302). Wetlands are evaluated as whole systems and the majority of this wetland extends off-site to the west and north. It is thereby regulated by both the U.S. Army Corps of Engineers and Jefferson County. Soils in the vicinity are mapped as Whidbey gravelly sandy loam. Soil pits dug on the upland portion of the site confirm this classification, matching the description by the Jefferson County Soil Survey. Wetland soils, however, are altered by the presence of water and are very dark brown (Data Point #1, 10YR 2/1 and 10YR 5/2 with mottles of 10YR 5/6 and sandy loam in texture). These soils typically consist of a layer of topsoil with an underlying impervious clay layer. The clay layer causes storm water to flow laterally, thus creating wetland and saturated areas wherever there is a dip in topography. Upland soils are dark brown on top with a hardpan or compressed clay layer below (10YR 3/3). This soil does not classify as a hydric soil. Upland soils were dry and compacted while the wetland soils were moist and very easy to dig. Bergstrom Delineation Report Report File Number 2001-00524 Olympic Wetland Resources. Inc. 7/{)1 Vegetation Vegetation in the wetland consists of a forest cover of alder, cedar, and willow. The dense shrub layer consists of salmonberry, Douglas' spirea, rose, and young willow. Wetland emergent species include cattail, common rush, willowherb, false lily of the valley and a variety of wetland tolerant grasses (fescue and hair grass). Water parsley and pond weed were observed in the open water portion of the wetland. These two obligate wetland species indicate that the water table is near the surface year-round and that soils consistently remain moist. Table 1. presents a summary of vegetation found on site.

At the wetland/upland edge soils were saturated but water did not fill the soil test pits~ this is common during the dry summer months. The soils prove that, historically, water has been present over an extended period of time with the presence of mottling and low chroma coloration. Recommendations In general, every effort should be made in the planning process to avoid impacts to wetlands and their buffers. No roads, buildings, septic systems, or clearings should be planned in these areas. In areas where impacts are unavoidable, the County may allow for alterations as long as they are fully mitigated. Typically, impacts will be mitigated by creating or enhancing wetlands or buffers. Each situation is evaluated on a case-by-case basis. It should be noted that any mitigation or enhancement is usually very costly, therefore it is recommended to avoid impacts whenever possible. Summary A Class II wetland was identified and delineated on the subject parcel. Wetland edges were confirmed by data points. The majority of thc wetland extends off-site and has not been mapped on the critical areas map. The wetland classi~es as a moderate to high quality wetland due to species and structural diversity, size, and undisturbed buffers on the subject property. Existing buffer areas to the west and south arc degraded and consist of parking lots and roads. The presence of open water adds to habitat value by increasing thc diversity of species using the wetland. Class II wetlands are assigned a protective buffer of 100 feet. Buffers are measured perpendicular to the delineated wetland edge and are indicated on Map~4 in the Appendix. Final authority over all wetland determinations rests with Jefferson County Department of Community Development, Critical Areas staff, and the United States Army Corps of Engineers. A copy of this report has been prepared for submittal to Jefferson County Department of Community Development and Tillman Engineering.
