1.3 The buffer along the western edge of the Wetland A may be decreased by SOX through buffer width averaging. The recommended area of buffer width reduction is east of the bua parking lot; this will allow for eapanaion of parking 1n this area in lieu of losing parking along the southem boundary for che purpose of creating a wildlife corridor (see condition 2). Because ihe filling of Wetland D will be significantly reduced, the area of wetland mitigation in Wetland A will also be significantly reduced. This mitigation area could, therefore, be used for buffer width averaging. 1.4 Create a buffer along the northern edge of Wetland A which is preseatly maiutained as a lawn area. This will require re-planting of this area with native wetland buffer species. � 1.5 Create a 50-foot wide wildlife corridor along the southern property boundary. Fill only that portion of Wetland D that is outside of the wildlife corridor; fill shall be sloped at 3:1 into the wetland. Reduce buffer for Wetland D to 25 feet for northern portion of the wetland. The purpoae of this condition is to create a continuous wildlife corridor which connects several major wetlan3s on the Mukilteo plateau with the shoreline area and Itasch Bog. The Community Transit Project (immediately east of the Mukilteo site), has been conditioned by the city to restore wetlands acd create a continuous wetland and wildlife corridor along its souihern property boundary. This corridor will abut the proposed Mukilteo wildlife corridor. 1.6 Mitigate for remaining fragment of Wetland C because its small size creates a nonfunctional wetland area. 1.7 Stockpile the hydric soils and plant layer from Wetlands B, C and portion of D to be filled. These materials shall be used in the creation of new wetland area in Wetlands E and A. 1.8 Aaalyze onsite hqdrology of Wetlands A, D and E to determine source and quantity of eziatiag wetland hydrolagy. Demonstrate that proposed project will aot impact the hydrological requirements of these wetlands and tt�at sufficient hydrology will be present for proposed created areas. 1.9 Eliminate or significantly reduce the present and future traasport of organic and inorganic pollutants into the onaite wetlands. This includes relocation of the animal aorral adjacent to Wetland E so that nitrate/nitrite pollut�ats are either rransported to an appropriatp stox� sewer system or treated onsite, and construction of a bioswal�, per pu�blic works standards, to treat any runoff from new parking lot axeas. 2.0 Relocate the eaisting development outside of the wetland buffer areas, including the animal corral ad3acent to Tietland E. -8-
