Throughout the SMP document, the term "Shoreline Jurisdiction" is used to describe the water and land areas subject to shoreline jurisdiction in Tukwila. Based on SMA guidelines for shoreline jurisdiction, Tukwila's Shoreline Jurisdiction is defined as follows: The shoreline environment map shall be reproduced showing parcel boundaries and at a minimum scale of 1 inch representing.

Staff recommends including this language in the SMP. Ecologv Staff Finding: While the SMP has provisions for standard prescriptive buffers, it also makes provision for reduced buffers if levees are modified to reduce their profile and allow for 15 foot wide area for vegetation. As proposed, the SMP contains some scenarios where there could be no minimum buffer when reduced pursuant to the SMP. The SMP contains natural environment and habitat use policies in Section 6.9 that require no net loss of ecological function and requires protection of wildlife, vegetation, wetlands, and watercourses. Table 3 within the SMP requires, in many cases, that buffers that are reduced under these provisions to be no less than 50 percent of the width of the standard buffers. Given that the standard buffers in question are 100 or 125 feet, this results in a modified buffer that is no less than 50 feet. In order to ensure internal consistency with these portions of the SMP, a required change to the SMP specifies that the buffer must be a minimum of CL Pa;c l' of 55 04/29/201 l 3:30:00 PM W:ALon, Rangc Projects \ShorelineAEcolo,y Review Adopted SMY\Required Changes Comparison Matrix TUKWILA SHORELINE MASTER PROGRAM: ECOLOGY AND 1 CHANGES COMPARISON MATRIX Council Adopted SMP Page Council Adopted SMP Text 1 AND t Ecology Finding/Staff Comments 50 feet when the buffer reduction standards are met.

If a change of use is proposed to a use determined to be non conforming by application of provisions in this SMP, the proposed new use must be a permitted use in the SMP or a use approved under a Conditional Use Permit process. For purposes of implementing this section, a change of use constitutes a change from one Permitted, Conditional Use category to another such use category as listed within the zoning code. 5. A structure that is being or has been used for a nonconforming use may be used for a different nonconforming use after demonstrating the following criteria have been met: a. No reasonable alternative conforming use is practical, b. The proposed use will be at least as consistent with the policies and provisions of the SMP and as compatible with the uses in the area as the preexisting use, c.

The applicant restores and or /enhances the entire shoreline buffer, including but not limited to paved areas no longer in use on the property, to offset the impact of the change of use per the vegetation management standards of this program.

Additional Information Provided by Ecoloav: This provision allows that existing structures in a Residential Environment do not need to be considered nonconforming as to the SMP residential structure standards or use. By referencing the SMP shoreline environment rather than the zoning code, zoning code provisions are not incorporated into the SMP.
