All critical areas within the City of Port Tov~nsend are regulated according to the Fort Townsend Municipal Code Critical Codes Ordinance {N0.2899, July 2005 PTMC}.Description of Site Legal Description: Parcel #964 200 701 {702} Section 4 Township 34N Range 1 W Location: 2827 Katherine St. (undeveloped) North of Hastings St and West of Thomas St.Soils: TuC Tukey gravelly loam and CmC Clallarn gravelly sandy loam Slopes: 0 to 1 S% slopes The parcels are located near a portion of the wetland described by Palazzi in 1994 as Deering Wetland ( WL#9-1). Deering Wetland is located at the top of Basin 9. This wetland is contiguous with North Deering Wetland (WL#5-4} located at the top of Basin 5. Although the dividing point between the two wetlands is unclear, due to the flat topography, it has been categorized as one wetland. Open pastures, roads, and development have fragmented this large seasonal wetland.Level A Assessment F[intReport File Number 2006-0131Olympic Wetland Resources, inc. Oi/06 Findings An arm of the Deering. Wetland extends down the undeveloped section of 29a` Street to within 55 feet of the northeast corner of parce1 964 200 702. A drop in topography and a dominance of wetland vegetation, which includes slough sedge, willows, and spires, def nes the wetland. The wetland edge was not delineated during this Level I Assessment. Using the Department of Ecology Wetland Field Data Farm {04-06-025) this wetland rates as a Category II wetland (52 points). All Class II wetlands with a moderate to low level far habitat function receive protective buffers of 100 feet. Enclosed is the Wetland Rating Forrn. The wetland was previously was rated as a Category II wetland by Palazzi. It is therefore not recommended that Katherine Street (within 100 feet of the wetland} or 29t~' Street {in the wetland) be developed. Please f nd the enclosed map with findings from the Level I Assessment. Currently the understory vegetation has been cleared on the majority of parcel 964 200 702 and along Katherine Street. The large trees are still present.
