CMI Homebuilder's Inc. SITE NAME: Wetland Delineation and EXECUTIVE SUMMARY Augusta Woods SITE LOCATION: The subject property is east of 18"' Avenue W(also known as Loganberry Lane) in Everett, Washington. The map location is found ir the SE'/< of Section 14, Township 28 North, Range 4 East, W.M. in the Paine Field area of the City of Everett. CLIENT: PROJECT STAFF: FIELD SURVEY: CMI Homebuilders Inc. Bill Shiels, Principal; Ann Olsen, Project Manager December 12, 1997 Hl'DROLOGY: Soils within the wetland generally consisted of a muck that was saturated to the surface, with several inches of ponding observed in places. SOILS: The Natural Resources Conservation Service (NRCS), formerly the Soil Conservation Service (SCS), has mapped the entire site as Alderwood — Urban land complex, 2 to 8 percent siopes. Although this mapping unit is not listed as hydric by the NRCS, it may have hydric soil inclusions. VEGETATION: Vegetation within the wetland consists of a mixture of palustrine deciduous forested and palustrine scrub/shrub components. Dominant plant species include red alder, Pacific willow, Sitka willow, salmonberry, spirea, skunk cabbage, lady fern, and creeping buttercup. DETERMINATION: One wetland (Wetland A) was identified and delineated throughout the west-central portion of the project site. The wetland consists primarily of a broad topographic swale that extends off-site both to the north and south, and is associated with a small drainage that flows south through the wetland. The northem portion of the wPtland has been historically filled and currently consists of an excavated ditch separated from the main portion of the wetland by a culvert under an existing old driveway. PROPOSED PROJECT: The proposed project consists of the development of 46 single family detached condominiums, with an entry road, intemal road system, associated parking, and an underground stormwater detention vault. Access to the development wili be from 181h Avenue West. Access to the eastem portion of the site will require crossing Wetland A, thereby having a direct impact of 2,007 sf. MITIGP.TION: The City of Everett requires a 3:1 replacement-to-loss ratio for impacted Category II wetlands that are forested (Wetland A). The total required mitigation for impacts to Wetland A is 6,021 sf. Mitigation for impacts to Wetland A will occur adjacent to the northeast edge of Wetland A. In addition to this, buffer reduction and averaging will be utiiized for the develupment. 201day 2003 Talasaea Consultants, LLC 2 3Fi4GMitRnt4l20Mav031 dnr. Paor. i J;, :�
