The results of technical studies, property owner willingness to participate, and the <br /> restoration design process may result in changes to the proposed restoration boundaries <br /> and phasing. <br /> The Habitat Restoration/ Recreation Phasing Figure shows 4 phases of <br /> implementation, with the lowest cost and least complex portions of the <br /> restoration occurring soonest. For examples,Phases 1 - 3 can be <br /> implemented without relocating the Marshland Flood Control District <br /> pump station. <br /> Phase 1: The Phase 1 area is close to the river, on existing public land, and requires no <br /> changes to the flood control infrastructure(Marshland Canal and pump station). It would <br /> require a new connection to the river that would include a new bridge through the <br /> existing river levee on Lowell Snohomish Road. It would also require two new dikes, <br /> one paralleling the Marshland Canal on the east side and one bordering private property <br /> on the south side. The dike on the east side of the Marshland Canal would be temporary <br /> until Phase 4 is implemented; however, all of the material to build the dike could be <br /> reused in Phase 4. Phase 1 also includes low cost riparian habitat enhancement along the <br /> river shoreline. This phase's habitat improvements would provide high ecological benefit <br /> to fish and wildlife including substantial tidal marsh restoration. Phase 1 should include <br /> development of an unsteady hydraulic model for the entire subarea to understand how <br /> water flow will occur with the subarea. <br /> The portion of Phase 1 located outside the City limits would be implemented by <br /> Snohomish County as mitigation for County Public Works projects. <br /> Phase 2: The second phase is shown on private land that provides another substantial <br /> tidal marsh restoration opportunity without changes to the Marshland Canal and pump <br /> station. It requires acquisition of private agricultural land by a public agency prior to <br /> implementation. The current owner of this property is supportive of the restoration plan <br /> and is willing to sell. A new permanent dike would be required around the perimeter of <br /> the Phase 2 property; a portion of this dike adjacent to the existing Marshland Canal <br /> would be temporary. This tidal restoration would require a new connection to the river <br /> that would include a new bridge through the existing river levee on Lowell Snohomish <br /> Road and a channel under an existing BNSF Railway trestle. A connection to Wood <br /> Creek would occur in Phase 4. Excavation for the relocated Marshland Canal <br /> (implemented with the Flood Control Structure Relocation in Phase 4) could occur during <br /> Phase 2. Material excavated for the future canal could be used as material for the <br /> temporary dike. This material could again be reused for the permanent dike along the <br /> western edge of the restoration proposed in Phase 4. Phase 2 would nearly double the <br /> ecological benefit from restoring high value tidal marsh habitat included in Phase 1. <br /> Phase 3: This phase occurs on mostly private land and is one of largest phases in terms <br /> of acreage. This phase would require acquisition of private agricultural land by a public <br /> agency prior to implementation, except for lands owned by Puget Sound Energy. No <br /> changes to the Marshland Canal or pump station are required for Phase 3 to be <br /> 21 <br />
