51TE DESCRIPTION On September 26, 2011 Wetland Resources, Inc. completed an investigation of the 0.55-acre property located at 4931 Seahurst Avenue in the City of Everett, Washington. The purpose of this site investigation was to evatuate jurisdictional wetlands and streams, on and in the vicinity of the subject site. This site is further located as a portion of Section 36, Township 29N, Range 4E, W.M. Land use in the area is comprised of residential devela�ment. 7his report was prepared by Louis Emenhiser who also conducted the fieid-work. Louis is a ceRified Professional Wetland Scientist with a Masters Degree in Soil Science and over ten years of prufessional experience. Access to this site is from the west via Seahurst Avenue. The entire site has an east aspect slope and contairs one single-family residence with a garage, associated lavon, and scattered trees extc�nding to the property boundaries. East of the subject site, Seahurst Glenhaven Creek and an associated Category II wetiand drain north towards Possession Sound. The area between the creek and the subject property contains an approximate forty-foot wide fringe of mostly native vegetation with patches of Himalayan blackt�erry. A chain link fence demarcates the property line with the buffer area on the site comprised of maintained lawn. In tfie City of Everett, Category II wetlands with habitat scores of less than 19 receive 75-foot protective buffers. When the buffer of a Type Np stream is sparsely vegetated, un-vegetated, or is vegetated with invasive species, the standard bufier is 75 feet. PROJECT DESCRIPTION The applicani is proposing to remodel the existing house. As a part of this remodel, tha footprint cf the existing house will be expanded to the east. While this expa�s:on will increase the footprint of the house tow3rds the wetland and stream, all new deveiopment will occur at least 100 fee� away from the 75-foot welland buffer. As a result of the distance of the proposed �vork from critical areas, this project will maintain the existing level of functions and values provided bv this subject wetland, stream, and buffers. EMC 19.37.110(A{6}), requires that buffers that are not comprised of relatively intact native vegetation be enhanced to the required buffer width (in this instance 75 feet). On lhis site, a portion of the wetland and strearn buffer is comprised of maintaned lawn and is lacking in tree or shrub cover. However, ihis buffer is not proposed to be enhanced as this lawn is a legally constructed improvement that was �n existence prior to April 28, 2006 (lhe effective date o(this ordinatnce), and is therefore, exempt per EfvIC 19.37.050 Section 5(2). Becavse the buffer on the subject site will be maintained as iawn, the required critical area sign will be installed on the chain link fence that currently comprises the boundary, between the native vegetation and the lawn. No additio�al fence is proposed. „ohnson— Se2hurst Ave. 1 WRI# i 1102 Cri6cal Area S�udy Sepfember 28, 2011 3 /� �T�
