Exhibit 1 1 3 Water-dependent and water-related uses shall be prohibited where they would require new dredging, fill, piers, or other significant modifications in areas designated Aquatic Conservancy. All nonwater-dependent and nonwater- related uses shall preserve and enhance existing native shoreline vegetation per the requirements of EMC 19.37 and shall provide environmental restoration, when feasible. c. The Urban Mixed Use Industrial Properties along Union and Steamboat Sloughs are not located adjacent to a federally maintained navigation channel. In these areas, nonwater-dependent and nonwater-related uses shall be permitted within 200 feet of the ordinary high water mark provided such uses provide substantial public access and public enjoyment of the shoreline. Water-dependent and water-related uses shall be prohibited where they would require new dredging, fill, piers, or other significant modifications in areas designated Aquatic Conservancy, or in the aquatic area west of Smith Island (AU 3.05). All nonwater-dependent and nonwater-related uses shall preserve and enhance existing native shoreline vegetation per the requirements of the SMP and shall provide environmental restoration, when feasible. Regulations in SMP Section 6 Shoreline Modification Activities page 6-9 13. Many of the 2001 SEWIP assessment units designated Aquatic Conservancy in Section 4 of this SMP as well as the aquatic area west of Smith Island (AU 3.05) received high rankings partially due to high quality marsh edge and/or riparian vegetation along dikes adjacent to the aquatic areas. Where structural flood hazard reduction measures are needed to protect development inland from these dikes, when feasible, new dikes or other stabilization structures shall be constructed inland of the existing dikes, and the high quality vegetation shall be preserved and enhanced along the existing dike. Regulations in EMC 19.37 37.100 Standard wetland buffer width requirements (page 704-278) A. Standard Buffer Width. The following minimum buffers of native vegetation shall apply to wetlands based upon the wetland category. Buffers shall be measured from the wetland boundary delineated as required by subsection 37.090A. If the designated buffer contains significant vegetation with drip lines extending beyond the edge of the buffer, the buffer shall be extended to five feet beyond the outside edge of the drip line. For purposes of this section, "significant vegetation" means a healthy evergreen tree, ten inches in diameter or greater, measured 4.5 feet above existing grade. 1. Category I: one hundred feet; 2. Category II: seventy-five feet; 3. Category III: fifty feet; 1 J 7 Section 3 General Goals, Objectives,Policies and Regulations Page 3-87
