The majority of property is rolling pasture land with shrubs along the fence lines. A central feature of the property is a 2 to 3 foot ditch run. nag north to south. Field work; Nvas conducted on June 22 °d 1998. Prior to the site visit Port Townsend Wetland Maps, Jefferson County soil survey maps, and National Wetland Inventory (NWp maps were reviewed Although no hydric soils are listed, wetlands, wet areas and/or drainage corridors are indicated on the City of Port Townsend maps. To the south east of the property TNWI maps indicate a ponded area listed as PSSC (Palustrine, Scrub /Shrub, Seasonally flooded). During the June field survey, ponded water was observed in the ditch near the north east corner to depths of 7 inches. Although no surface saturation was observed in any of the upland areas, hydric soil was identified (Data point #2 2.5Y 512 with mottles) and obligate wetland vegetation was found (Alopecurus sp., Foxtail OBL). It is common this time of year for seasonal wetlands to be dry. Please refer to the attached map for approximate locations of the potential wet areas identified during the June field survey. Note that wetland edges are approximate and this map is not to be used for exact planning purposes. This wetland is not isolated and has some connection to wetlands across Hastings and downslope to ponded areas within drainage basin #9. A Department of Ecology wetland classification was conducted at this time near Data Point # 2, south of Hastings. The classification of this area is a low quality Class III wetland with a rating of 10 points. A Class III wetland has an associated 50 foot buffer from the delineated wetland edge. If this wetland area was isolated it could potentially qualify as a Class IV wetland due to lack of structural diversity, minimal vegetation types and lack ofhabitat values. Due to the ponded water on site and the location ofthe property, at the head of drainage basin 99, further work may be required by the City of Port Townsend Environmentally Sensitive Areas Ordinance prior to any development. If you find you need a wetland delineation or have any questions please don't hesitate to call.
