2005/08/10 Council Agenda Packet

1 • 13 Exhibit 1 • Where structural flood hazard reduction measures are needed to protect development inland from Aquatic Conservancy areas and AU 3.05, when feasible, new dikes or other stabilization structures shall be constructed inland of the existing dikes. (SMP Regulation 13 on page 6-9) • As properties redevelop, buffers must be enhanced/restored. Buffers are based on a biological evaluation to assure no net loss of function and must be a minimum of 200 feet on or adjacent to areas designated Aquatic Conservancy and AU 3.05. (SMP Regulation 11 on page 3-31, Revised Regulation 22 on page 3-32) • Interior wetlands on Smith Island north of 12th Street, on North Spencer Island, and the city-owned property southwest of Weyco Island are categorized based on SEWIP Wildlife Function. Buffers are based on a biological evaluation to assure no net loss of function. Minimum buffer widths range from 200 to 50 feet. • Buffers are based on a biological evaluation to assure no net loss of function and a 100 foot buffer is required from Smith's Slough. (Buffer requirements in EMC 19.37.100.A.1, Category 1 Wetland, Appendix A, page 704-278) • If nontidal mitigation is proposed for loss of nontidal palustrine wetlands, it should be reviewed to ensure that opportunities to recover tidal function would not be foreclosed. (SMP Regulation 35A.4. on page 3-36) • As redevelopment occurs, unnecessary impervious surfaces shall be removed and shoreline buffers enhanced/restored, except as necessary for access to the water. The Planning Director can require redesign to minimize impacts to existing vegetation and to provide for buffer enhancement. (SMP Regulation 11 on page 3-31) Other mechanisms. Permits for properties adjacent to Smith Slough will include provisions that preserve the opportunity to reconnect the slough consistent with SMP Regulation 35.A.4. 129 Section 3 General Goals, Objectives,Policies and Regulations Page 3-59
