implemented. The scope of this phase entails mostly restoring non-tidal freshwater marsh to areas that are currently agriculture. In cases where existing wetlands occur they would be preserved and enhanced. These restoration actions are low cost and mainly involve decommissioning of drain tile systems and protecting adjacent lands from hydrologic changes. Phase 3 also includes recreation amenities, such as trails, small parking areas, and passive open space, along Lowell Larimer Road. Phase 4: The greatest changes to infrastructure are included in this phase. It also covers the largest area; however, it mostly occurs on publicly owned land. The major infrastructure changes include relocation of the pump station to the southern boundary of the site and relocation of the Marshland Canal through the southern tidal wetland area implemented during Phase 2. Other elements of this phase include a hydraulically controlled culvert connection to the land in the northwest portion of the site, two water channels below existing BNSF Railway trestles, improvements to the lower Wood Creek channel, and a flume connection conveying Wood Creek to the an expanded tidal marsh. Phase 4 involves extensive dike construction to protect adjacent private lands, and relatively limited private property acquisition. Phase 4 has high ecological benefit, but requires significant costs to implement major infrastructure changes. b. Schedule: Implementation of the project will occur as funding allows. The subarea plan could be implemented in phases as described above. Phase I would occur as funding is received and the appropriate environmental investigations and technical issues are resolved. Phase 2 requires acquisition of private agricultural land and is part of another restoration opportunity. Phase 3 involves the most land of all the phases and also requires the acquisition of private agricultural land for restoration and/or voluntary property owner restoration/mitigation. Phase 4, the final phase, includes recreation and changes to the infrastructure in the project vicinity. Due to the changes in infrastructure, this phase involves substantial costs and would therefore be dependent on funding opportunities. It is understood that private landowner willingness may change over time. It is the intent of the City to be opportunistic about landowners shifting their decisions as the project moves forward. Such changes may provide more land for restoration and aid various project objectives. c. Costs/Funding Sources: The scope of the habitat restoration proposed in the subarea plan is sufficiently large to necessitate phasing. For planning purposes, a feasibility planning level cost opinion estimate for the phased implementation of the Preferred Plan was developed. Table 5-4 summarizes the expected magnitude of project costs associated with general requirements, earthwork, structures, restoration and enhancement, recreation, and land acquisition for each proposed phase of implementation. These are planning level opinions of probable cost developed for comparative assessment of alternatives. These cost opinions should be re-evaluated and updated once funding is secured, previously described studies are completed, and detailed engineering designs are developed. 22
