DIRECT INQUIRES TO: Georgia Hudson, Senior Procurement Specialist TELEPHONE: (352) 505-2970; FAX: (352) 754-3497 Email: procurement@watermatters.org The scope of work includes providing all necessary materials, equipment, labor, and ancillary items to complete the Project described in the RFB, Plans, and Technical Specifications in a satisfactory manner. The Three Sisters Springs Shoreline Stabilization Project involves the restoration of eroded shoreline surrounding the springs and will utilize soil bags to backfill undercut bank areas and limestone rock to reinforce the shoreline. The Three Sisters Springs have a water surface area of approximately one acre and nearly 1,200 linear feet of shoreline. The property surrounding the springs is jointly owned by the District and the City of Crystal River (City). The property and the springs are managed as a National Wildlife Refuge by the U.S. Fish and Wildlife Service (USFWS). Shoreline stabilization utilizing limestone rip-rap has been completed on limited sections of the bank and the lower spring run (as shown in the Plans). The Three Sisters Springs Canal Shoreline Stabilization Project is located within the 57-acre Three Sisters Springs Property, in Citrus County Florida. The property is jointly owned by the District and the City. The property is managed by the USFWS as part of the Crystal River National Wildlife Refuge. This project is within the Crystal River/Kings Bay watershed, a Surface Water Improvement and Management (SWIM) priority waterbody and an Outstanding Florida Water. Crystal River/Kings Bay is a tidallyinfluenced waterbody and is a popular destination for water related recreational activities, including boating, kayaking and snorkeling. The primary objective of this project is stabilization and restoration of approximately 400 linear feet of eroded shoreline utilizing soil filled ENVIROLOK(TM) bags for reestablishment and anchoring of plants and limestone rocks to protect the shoreline from wave and tidal action, recreational uses and manatee grazing while preserving the overall aesthetics of the spring. The location of the project is the shoreline around the confluence of the Three Sisters Spring run with the canal, which includes the area around Idiot's Delight spring. A similar project was completed within Three Sisters Springs. The construction project will utilize filter stone as a leveling substrate, ENVIROLOK(TM) bags to plant native wetland species in restored areas, sand filled burlap bags to fill undercut voids, and limestone rip-rap to stabilize and protect the burlap and ENVIROLOK(TM) bags. Other required construction items include project staging and mobilization, erosion control, water quality protection, waterway navigation management, site clearing & grubbing, wetland planting, existing boardwalk removal, temporary construction access, and site restoration including grading and grassing of areas disturbed by the construction contractor. The project requires the Contractor to maintain all areas within the project limits free of non- native and, as needed, nuisance plants, for a period of one year, following final completion.
