' Wetland C - Category II Wetland C is a depressional wetland with no outlet. Forested vegetation dominates Wetland C. This wetland is part of a wetland mosaic existing in the southeastern corner of the site. Based on its score for functions on the Wetland Rating Form, Wetland C offers low levels of water quality improvement functions, low -moderate levels of hydrologic functions and moderate levels of wildlife habitat functions. Wetland D - Category III Wetland D is a depressional wetland with no outlet. It is primarily dominated by a scrub -shrub vegetation community with returning young forest. Based on its score for functions on the Wetland Rating Form, Wetland D offers low -moderate levels of water quality functions, low levels of hydrologic control functions, and a moderate level of habitat function. 3.7 WETLAND RATING Wetlands A through D have been rated using the Washington Department of Ecology (DOE) Wetland Rating Form for Western Washington (Version 2). Wetlands A and C received between 51 and 69 points, which equates to Category II classifications. Wetlands B and D received between 30 and 50 points, which equates to Category III classifications. 3.8 BUFFERS Pursuant to Everett Municipal Code, EMC 19.37, Wetlands A and C are designated 75-foot standard buffers, Wetland B is designated a 60-foot standard buffer, and Wetland D is designated a 75-foot buffer. 3.9 WATER QUALITY No waters on or adjacent to the subject property are listed on the 303d list for Washington State. 4.0 MITIGATION APPROACH 4.1 MITIGATION SEQUENCING Due to the location of the on -site wetlands and the mass grading that is required across the site, elimination of the four on -site wetlands is unavoidable. Wetlands A through C lie in the higher, southern portion of the site. Material from this portion of the site is required to be moved to the lower, northern portion of the site to create a relatively flat building site. Elimination of these three wetlands is also required to provide level access to the site from 36th Avenue West. Similarly, Wetland D lies in the center of the site where mass grading is required to balance the site grades. Avoiding impacts to these four small wetlands would make the project physically infeasible due to grading requirements and would therefore make the project economically infeasible. For loss of wetlands, the applicant is proposing to mitigate the unavoidable impacts through the purchase of credits at an approved wetland mitigation bank that has already been constructed. The Skykomish Habitat Mitigation Bank will be used for this project. Through the purchase of approved credits, all functions and values lost due to the elimination of the on -site wetlands will be immediately replaced within the same drainage basin.
