11.0 ADDITIONAL PROTECTIONS UNDER EMC In addition to standard critical area buffers, Everett Municipal Code contains the following requirements for protection: Pursuant to EMC 19.37.110(A)(1), "When feasible, a relatively undisturbed vegetated corridor at least one hundred feet wide must be protected between the wetland and any nearby priority habitat. Presence or absence of a nearby habitat must be confirmed by a qualfited biologist. If there is a presence of a nearby priority habitat and if the wetland has a habitatfunction score of six or more, a one -hundred foot -wide relatively undisturbed, vegetated corridor must be provided between the wetland and other priority habitats if there is a corridor available to provide." The riparian corridor associated with Stream A extends off -site to the south approximately 300 feet to 16th Place West. Per EMC, riparian zones are considered to be a priority habitat. The proposed site plan maintains the existing vegetated corridor, which is approximately 87 feet wide at the widest point and approximately 50 feet wide at the narrowest point. The proposed buffer enhancement plantings will expand the width of the corridor to include the entirety of the parcel outside of the development footprint. Once the trees and shrubs in the buffer enhancement areas mature, the forested riparian corridor will be approximately 90 feet wide at the narrowest point and over 150 feet wide at the widest point. This represents the maximum feasible protected corridor while accommodating reasonable use of the property. 12.0 BUFFER MITIGATION PLAN 12.1 MITIGATION SEQUENCING Mitigation sequencing outlined in EMC 19.37.085 has been carefully considered in the design of this project. As the subject parcel is entirely encumbered by the on -site critical areas and buffers, it is not possible to avoid impacts altogether. The applicant has designed the site plan to avoid any direct impacts to the on -site wetlands and stream and to minimize buffer impacts to the extent feasible. The proposed single-family residence is smaller than average in size as compared with others in the vicinity. It has been located as far as possible from the on -site critical areas and is situated in a portion of the site that currently consists of maintained lawn that currently provides minimal buffer function. The proposed buffer impacts represent the minimal amount required in order to obtain reasonable use of the property. 12.2 PROPOSED IMPACTS AND MITIGATION Unavoidable buffer impacts associated with the proposed single-family residential development total 4,227 square feet. The buffer area that will be impacted consists of maintained lawn. No natural vegetation will be disturbed. The applicant proposes to mitigate for the unavoidable buffer impacts by enhancing the remainder of the on -site buffer areas that consist of maintained lawn (11,616 square feet). These areas will be planted with a diverse mix of native trees and APV Ventures LLC—Dakota Way 14 Critical Area Report, Buf rMiti ation WRI #20015 Plan & Habitat Assessment April27, 2020
