Box K Shelton, WA 98584 Re: Wetland Delineation for a 10 acre parcel located on Probert Road, Mason County, Washington. This parcel is located in a portion of the NW 1/4 of the SW 1/4 of Section 28, Range 21 N, Township 2 WWM. Dear Don: I met with you and Gene Nye on May 3, 1995 to determine if wetlands were present on the above referenced parcel. I found that the Northeast portion of the parcel was comprised of a forested wetland associated with a large Lacustrine, Open Water/Aquatic Bed, Permanently Flooded wetland located just Northeast of the parcel. See enclosed portion of the National Wetland Inventory, Mason Lake Quadrangle. You accompanied me as I delineated the wetland boundary as required by the Mason County Interim Resource Ordinance (IRO) for all proposed Class IV logging practices. All wetland boundary determinations were made using the 1987 Corps of Engineers Wetland Delineation Manual as required by Mason County. This manual requires the use of the three wetland parameter methodology(wetland hydrology, hydrophytic vegetation, and hydric soils)when making wetland determinations. A combination of the Routine On-site, and intermediate Methods were used to make the wetland boundary determination. The on-site portion of the wetland was delineated with blaze orange flags numbered sequentially and with WB A written on them. Fifty-one wetland boundary flags were used. Five wetland test areas were investigated and marked with blaze orange and a white with orange polka dot flags. See enclosed wetland delineation map and enclosed wetland test area data sheets. A second, small wetland was identified approximately 40 feet Southwest of WB A-21; however, this area is exempted from provisions of the IRO because it is under one acre in 1015 S.W. Harper Road, P.O. Box 8612 Port Orchard.Washington 99366 (160) R?6_1401 Fa.v(UM R7(,_')(15l iJ Don Knudson May 8, 1995 page 2 size and is not hydrologically connected to the larger on-site wetland or to any other wetland or stream. This area was separated from the delineated wetland by an upland berm. The smaller wetland was marked in the field but not delineated because of its easily determined small size. The Mason County Interim Resource Ordinance requires a 50 foot vegetated buffer to remain around all regulated wetlands with a 15 foot building setback from the edge of the buffer. Buffers are measured perpendicular and landward from the delineated boundary. In addition to the vegetated buffer and building setback, a 35 foot management area shall be maintained. Activities occurring in wetlands that are under one acre and hydrologically isolated are exempted from provisions of this ordinance; however, any dredge or fill is limited to a one time cumulative total of 50 cubic yards. If you have any additional questions concerning this delineation, please feel free to contact Bob, Joanne, or myself at (360) 876-2403.
