The focus of the review was to determine the extent of regulated wetland vegetation areas encompassing the subject parcel. All fieldwork and reporting was completed by Lee Boad. Technical data is attached. 2.0 Methodology 2.1 Field Review A field review was performed on January 4, of 2005. An identified wetland was flagged, delineated, categorized, and mapped relative identified property lines. 2.2 Wetland Delineation Wetland delineation followed a routine methodology based upon the Washington State Wetland Identification and Delineation Manual (1997)requiring positive indicators of wetland soil,hydrology, and plants. Wetland hydrology was determined through observation of field indicators and conditions dug in pits within the study area. Presence of hydric soil was determined by soil conditions in several pits dug around and within suspected wetlands. Soil inspection included comparison with the Munsell Color Charts(1992). General soil characteristics were derived from information contained within the Soil Survey of Mason County, Washington. (1960). Occurrence of wetland vegetation was determined through species identification, estimation of dominance and then assignment of wetland indicator status. Indicator status was assigned based on the National List of Plant Species That Occur in Wetlands (1996). 2.3 Wetland Category Rating Procedures set forth in the Washington State Wetlands Rating System— Western Washington Second Edition were used to establish category ratings for identified wetlands. RECEIVED IJAN 10 2UM 426 W. CEDAk if'. 1 2.4 Wetland Mapping Wetland mapping consisted of a series of transect measurements taken from identified property lines to the wetland edge. 3.0 Results The soil series mapped throughout the entire property is Alderwood gravelly sandy loam. This soil type was confirmed in all upland sample plots taken within the parcel. An isolated wetland was identified on the adjacent parcel to the west. Positive indicators of soil, hydrology, and vegetation were observed within the suspected wetland. The wetland community was dominated by Spiraea douglasii and underlain by dark mineral soils(chroma 1). 3.1 Category III Wetlands The wetland identified is isolated in nature and only seasonally ponded. The wetland maintains a significant habitat value less than 22-points according the Wetlands Rating Field Data Form, qualifying it as a category III wetland. Factors influencing this rating include fish and wildlife habitat features, interspersion between wetland classes, association with fish bearing water, surface water connection to other waters, and structural diversity. A plot map is enclosed showing the location of identified wetlands. Boundary Description The wetland boundary exists at the toe of the slope located on the edge of the Spiraea community. Distinct changes in vegetation community and soil characteristics coupled with a moderate change in landscape provide an easily recognizable boundary between wetlands and non-wetlands. The western portion of the wetland was not flagged as it extended beyond the study site. A reconnaissance was conducted around the entire wetland to confirm isolation. Jurisdictional Status The wetland measures greater than 2,500 square feet in size. Category III wetlands greater than 2,500 square feet are considered jurisdictional in Mason County meaning all vegetation areas and building setbacks apply. A 50-foot vegetation area and a 65-foot building setback are required for category III wetlands in Mason County. Special setbacks include 100 feet for an on-sight sewage system and 200 feet for a livestock feedlot 4.0 Incidental Vegetation Area Encroachment Recent land clearing efforts have occurred within a portion of the regulated 50-foot vegetation area. An area of approximately 250 square feet has been cleared within the protected zone. It is recommended that this area be restored through native vegetation planting using the following guidelines. 2 4.1 Restoration Recommendations Plantings should be installed to achieve the following densities. trees- 10' on center shrubs-5' on center herbaceous groundcover—6 inches on center These densities would provide a moderately dense, structurally diverse plant community within the restoration area. Native plant species that should be used within the restoration zone include: Trees: Douglas fir(Pseudotsuga menziesii) Western white pine (Pious monticola) Shrubs: Pacific rhododendron(Rhododendron Macrophyllum) salal (Gaultheria shallon) evergreen huckleberry(Vaccinium ovatum) Groundcover: kinnikinnik(Arcostaphylus uva-ursi) coastal strawberry(Fragaria chdoensis) Supplemented plants yield the highest survival if planted during winter dormancy. The optimum time for planting is during February and March. 4.2 Monitoring Monitoring of the site will begin the first fall following project completion and maintained on a seasonal basis. The information gathered will provide the following: 1) recruitment of plant species and condition of reintroduced species; 2)the use of the site by wildlife species; 3) any occurrence of exotic species within the restoration zones; 4) any corrective measures that may be deemed necessary to provide desired conditions. This monitoring will be in effect for the duration of three years. The information gathered will be provided in an annual report and submitted to the Director of Mason County Department of Community Development. 5.0 Conclusion Wetland delineation has been completed within a targeted portion of the adjacent parcel applying methodology required by the Mason County Wetland Ordinance. One wetland zone was identified. A portion of the regulated vegetation area has been incidentally cleared. Restoration guidelines have been provided. A plot map is enclosed showing the wetland location, associated setbacks required by Mason County, and location of incidental clearing within the regulated vegetation area. 3 Lee Poad Habliat Manaclemerrt planning and Wetland 5ervice5 Owner; Jerry & Katy Martin Site; parcel #22"-I5-00320 PO Dox 3295 Delfair, WA 98528 scale; 1"=90'=0'' Cateom III / c� ArmWetland Unintentionallu Cleared Area w � � I Routine Wetland Determination DATA FORM 1 (Revised) WA State Wetland Delineation Manual or 1987 Corps Wetland Delineation Manual Project/Site: Adjacent west of Parcel 22309-75-00320 Date: January 4, 2005 Applicant: Jerry Martin County: Mason Investigator(s): Lee Boad State: WA S/T/R: Sec 9 T23N R2W Do normal circumstances exist on the site?
