Review was limited to the suspected wetland that occurs nearest to the existing driveway. Technical data is attached- Methods Field Review A field review of the above referenced properties was performed on January 23, 2002. The suspected wetland occurred within both properties. A larger wetland was observed, however, boundary delineation and formal determination was not completed because the wetland is likely jurisdictional and the landowners will manage it according to Mason County Resource Ordinance 17.01.070. Wetland Delineation Wetland delineation followed a routine methodology batted upon the Washington State Wetland Identification and Delineation Manual (1997) requiring positive indicators for 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 hydrie soil was determined by soil conditions in several pits dug around 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). Wetland Category Rating The Washington State Wetlands Rating System for Western Washington (1993) was used to establish a Category Rating for the wetland. e Z00'd dee:eo 80/bZ/10 8b90-S4Z-09^c a5 luawaDueyu3 uowieS jeue3 POOH RESULTS Category III Wetland An isolated category ITT wetland was identified at the site. Positive indicators of soil, hydrology, and vegetation were observed within the flagged wetland. Several landscape characteristics indicate that the site is and has been capable of containing water long enough during the growing season to support wetland conditions. The upper 9 inches of histosol soil indicate condition-,of saturation long enough during the growing season to develop anaerobic conditions. This qualifies is a hydric soil. Hydrophytic vegetation was also observed throughout the wetland zone. All plants identified within the zone were either facultative or obligate wetland plants. The diversity of vegetation observed throughout the wetland qualify it as a category ITT according to The Washington State Wetlands Rating System for Western Washington (1993), Below Minimum,luristictional Size The identified wetland was flagged in the field and has a length of 64 feet and a mean width of less than 30 feet in size. A single island of non wetland occurs within this zone which subtracts roughly 50 square feet of wetland surface area from this estimate. This wetland has hydraulic connectivity to a small wetland channel via a culvert passing under the existing driveway. This channel ends 52 feet from the road and has a mean width of 7 feet. The overall surface area estimate for the wetland and 'associated wetland channel totals less than 2230 square feet. Category III wetlands less than 2,500 square feet are not regulated by Mason County according to chapter 17.01.070 of the Mason County Resource Ordinance. Because of the nonregulatory status of this wetland, no further information is required at this time. 1 trust this information is sufficient for your needs at this time.
