7 <br /> Implementation <br /> Schedule and Phasing <br /> The public amenities proposed in the master plan are expected to be constructed incrementally, to <br /> complement the private development activity and timed as agency reviews and permitting, multiple <br /> sources of funding, and abutting private and public project schedules allow.The projects, as previously <br /> described, are divided into Early Phase and Later Phase construction, establishing priority based on <br /> conditions as they are now known. Within each of the two phases, projects may be further divided and <br /> sequenced to best accommodate other projects or to take advantage of available funding. With <br /> completion and adoption of this document, final design documents may be prepared, with initial <br /> construction of some portion of the Early Phase projects occurring in 2010. Other target dates for <br /> construction are tied to milestones in the private development schedule. See the Project Areas Plan <br /> foldout following for general boundaries of project areas and responsible agencies. . <br /> Early Phase Projects <br /> The initial phase'of the Public Amenities Master Plan design and construction is likely to encompass <br /> the Bigelow Creek restoration, including the creation and enhancement of additional tidally influenced <br /> wetlands within the South Wetland Complex. This work will include the construction of a low berm to <br /> isolate the tidally-influenced areas from Wetland D, which is encumbered by the Restrictive Covenant, <br /> and from off-site portions of the South Wetland Complex in the WSDOT parcels. This work may also <br /> occur in conjunction with the construction of the surface water quality improvement facility. Early Phase <br /> work would also entail additional wetland creation or buffer enhancement as mitigation efforts.Although <br /> this work is a priority for the city, the construction of both the Bigelow Creek restoration and the <br /> constructed wetland surface water project are contingent on outside funding and, as such, are largely <br /> outside of city control. <br /> The proposed re-alignment of the Riverfront Trail at the new Bigelow Creek outfall and the construction <br /> of the trail's Trestle Bridge are integral project elements that will maintain trail continuity and minimize <br /> future disruption. Because trail and bridge construction typically cannot be funded from the same grants <br /> available for water quality improvements or habitat enhancements, these portions of the planned work <br /> will require separate, supplemental funding. <br /> The construction schedules of abutting projects may encourage the early phased construction of the <br /> proposed Railroad Corridor Trail. Improvements to the Landfill site's leachate collection system, the <br /> piped routing of offsite stormwater, and the removal of the Landfill site preload soils are three <br /> independent but linked efforts that will demand construction road access. The abandoned BNSF track <br /> bed at the base of the Landfill, supplemented by Landfill site preload soils, can provide a low-cost, <br /> stable bed for the construction road. Another independent project, the relocation of an existing PUD <br /> tower within the transmission line easement, can employ the same construction access, possibly at the <br /> same time as other construction work. After the utility upgrades and site grading are complete, the <br /> access road can provide the base for the pedestrian and bicycle route identified as the Railroad <br /> Corridor Trail. This route will continue to provide maintenance and emergency vehicle access along its <br /> length. The trail construction will likely be staged to complement the needs and pace of the private <br /> development,with the public investment paralleling the private investments. <br /> To maintain continuity of public trail use, an important criterion set by the city, the scope of Railroad <br /> Corridor Trail work will include creating a trail linkage of boardwalk and bridge segments to connect to <br /> the Simpson Pad and the regional trail at the north end of the Simpson Pad site. The private <br /> developer's schedule for the relocation and widening of the north segment of the regional Riverfront <br /> Trail, replacing the existing paved trail, will factor into the precise alignment and timing of this Railroad <br /> Corridor Trail connection. <br /> Riverfront Development Public Amenities Master Plan 43 <br /> 78 <br />
