13 Exhibit 1 buffer along Union Slough and creation of a 4-acre wetland along the interior slough. Tidal restoration of the part of the site where the compost facility is located is no longer feasible during the lifetime of that operation. Potential restoration actions still include: • Restoration of tidal action to the interior slough, with plantings of additional riparian vegetation along the slough. This will require dikes along both sides of the slough. • Construction of a setback dike along Steamboat/Union Sloughs. This would allow the area waterward of the new dike to revert to tidal action. The dikes would have to protect adjacent properties. Technical difficulties include removal of wood waste in the buffer along the western part of the site. c. Smith Island: BMC West Property and (Salmon Overlay Site 21 on Figure 4.16). Potential gain of 761 IVA acre-points. Technical difficulties on this site include potential conflicts with power lines, relatively long dike needed for area restored, and protection of the highway. This could result in a high cost for dikes relative to the area restored. d. Smith Slough tide gate removal. (Salmon Overlay Site 23 on Figure 4.16). This tributary slough once connected the Snohomish River mainstem and Steamboat Slough. This project would require an approximately 9,200 foot dike on the outer edge of this slough, and removal of the tide gate on Union Slough. Potential gain of 400 IVA acre-points. e. Potential log storage removal enhancement on northwest and south sides of Smith Island. Potential gain of 627 IVA acre-points on south side of Smith Island. Only a part of assessment unit 3.05 on the northwest side of Smith Island is in the City limits. The potential gain has not been assessed separately for the portion in the City limits. A gain of 4,609 IVA acre-points could be gained if log storage was removed from all of AU 3.05. 3. Regulations in the SMP that Promote Restoration of Shoreline Functions (apply to public and private property) • Water-dependent and water-related development is not allowed adjacent to AUs designated Aquatic Conservancy and AU 3.05 on West side of Smith Island. (SMP Regulation 2 on page 5-26; Regulation 1.c. on page 5-33; Regulation 4 on page 6-3) • Where nonwater-dependent/related uses are proposed, restoration of the shoreline and public access are required (essentially as the water-oriented component of the proposal). (SMP Regulation 2 on page 5-26, Regulation 1.c on page 5-32) 128 Section 3 General Goals, Objectives, Policies and Regulations Page 3-58
