Type F stream is sparsely vegetated, un-ve�ctated, or is v^�etated with invasive species, the standard buffer is 150 feet While it is likely that this reach af Swamp Creek supports some species of fish, no listed species are known to utilize this reach of Swamp Creek. There are no bald eagle nests in the project vicinity and no anadromous fish based on WDFW PHS maps and Snohomish County fish distribution maps. Profect Deacri�tion The applicant is proposing to construct a garden shed in the noRhwest corner of the property. Thfs area is currently comprised of maint�ined lawn and Qarden beds, and separated from the buffer of Swamp Creek by a six-foot tall, solfd board fence. Pursuant to EMC 37.170(C)(3), if a limited portion of the buffer has been pr�viously legally altered and meets the following crReria. a buffer width reduction may be approved for that portion of the required buffar only: 1. The required buKer area has been graded or substantially attered and hss not been substantially revegetated (i.e., the buffer is crovered with g�avel, impervious surface, mowed lawn, or is vegetated with primarily invasive species such as �eed canary grass, Hima/ayan blackberry, purple loosestrife, or other nonna:ive invasive species covering more than seventy•/ive percent of the bulfer area). Both the stream channel and the required buffer in this area have been substantially altered through historic grading. The stream was placed in a straight-banked ditch, and a detention pond was constructed just west of the subject property. In addition, the subject property and the adjacent properties appear to have been leveled prior to wnstruc'.ion. VegetaUon within both the detention pond and the area of the subject lot is dominated by maintained lawn. 2. Substantial clearing of the buffer H�as authorired and substantial �evegetation with native species has not occuned. Per conversations with the property owner, occasional maintenance is conducted by the City to remove trees and shrubs and maintain the existing grass. Based on the above, the applicant is proposing to reduce the standard 150doot buffer from swamp creek to the edge of the solid board fence and to construct a garden shed in the northwest corner of the property, on what is currently existing, maintained lawn. Stormwater from this shed will be collected and routed to splash blocks where it will infiltrate to the native soil. This approach wili maintain the existinQ hydrologic regime. Because the shed is proposed to be buiR in a place that is currently maintained lawn that is isolated from the buffer of Swamp Creek by an existing fence, the direct. indirect, and cumulative impacts resultant from this project wili be negligible.
