Implementation Strategies and Mechanisms <br /> 5.1.1.1 Phase 1 <br /> The Phase 1 area is close to the river, on existing public land, and requires no infrastructure <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 existing <br /> river levee on Lowell Snohomish Road. It would also require two new dikes, one paralleling <br /> the Marshland Canal on the east side and one bordering private property on the south side. <br /> The dike on the east side of the Marshland Canal would be temporary until Phase 4 is <br /> implemented; however, all of the material to build the dike could be reused in Phase 4. <br /> Phase 1 also includes low cost riparian habitat enhancement along the river shoreline. This <br /> phase's habitat improvements would provide high ecological benefit to fish and wildlife <br /> including substantial tidal marsh restoration. Phase 1 is the least complex phase and would <br /> therefore be one of the lowest cost phases. Phase 1 should include development of an <br /> unsteady hydraulic model for the entire subarea to understand how water flow will occur <br /> within the subarea. <br /> 5.1.1.2 Phase 2 <br /> The second phase is shown on private land that provides another substantial tidal marsh <br /> restoration opportunity without changes to the Marshland Canal and pump station. This <br /> phase would require 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 the <br /> Phase 2 property; a portion of this dike adjacent to the existing Marshland Canal would be <br /> temporary. This tidal restoration would require a new connection to the river that would <br /> include a new bridge through the existing river levee on Lowell Snohomish Road and a <br /> channel under an existing BNSF Railway trestle. Excavation for the relocated Marshland <br /> Canal (implemented with the Flood Control Structure Relocation in Phase 4) could occur <br /> during 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 high <br /> ecological benefit from tidal marsh habitat restoration included in Phase 1. <br /> Draft Subarea Plan June 2009 <br /> Everett Marshland 59 070346-01 <br />
