Restoration and Land Use Concepts roads • Wildlife Preservation/Enhancement—areas identified for habitat retention • Fish Preservation/ Enhancement—areas identified for habitat retention • Wildlife Preservation—Spane Wetland mitigation site • Fish and Wildlife Restoration—tidally restored public lands and private lands where supported by willing owners 3.3.1 Subarea Plan Outcomes This section compares how well the Subarea Plan satisfies the goals and objectives of the settlement agreement Meets objectives: • Provides an area for passive recreation and a large public trail system • Provides a large amount of habitat restoration • Provides fish access to Wood Creek by allowing it to outlet into a tidally-influenced wetland area rather than the Marshland Canal • Provides for fish passage into the Marshland Canal through or around the pump station • Provides fish access to the tributary channels from the adjacent hillsides Partially meets or does not meet objectives: • Requires significant infrastructure changes • Has a high cost 3.3.1.1 Proposed Habitat Types Habitat types are determined by number of factors including water depth and frequency of inundation, salinity, soil type, the ability to adapt to natural or human disturbances, and other factors. The Marshland subarea has been diked and in agricultural production for over 100 years. During this time it has been protected from daily tidal inundation but is still subject to periodic flooding. Typically, when land is diked and farmed for extensive periods of time, subsidence occurs. As a result, much of the area proposed to be restored to tidal inundation is relatively low, and is anticipated to initially be in a mudflat habitat type if no regrading to raise these areas occurs. The combination of daily tidal inundation and periodic flooding will change habitat types over time with sedimentation (raising of grades) and/or Draft Subarea Plan June 2009 Everett Marshland 36 070346-01
