About this file
This document is an Engineer's Estimate for two stream restoration and riparian reclamation projects funded by the South Carolina Office of Resilience (SCOR) through an ARPA-funded Stormwater Infrastructure Program (ASIP) grant for Greenville County. The project consists of two separate locations: Little Creek and North Chastain, totaling approximately 12 acres of restoration work. The projects involve stream restoration, reforestation, and riparian area reclamation along previously acquired floodplain buyout properties in the Reedy River watershed. The restoration work includes bank grading, soil lifts, coir and turf reinforcement matting, boulder walls, bank toe treatments, and installation of instream features like cross vanes, boulder riffles, and single arm vanes.
The total estimated project cost is $1,391,916.13, with the North Chastain project estimated at $591,483.83 and the Little Creek project estimated at $800,432.29. Key line items include mobilization, erosion and sediment control, clearing and grubbing, excavation, various stream restoration features, vegetation establishment, and plantings. All spoil material will be taken to Blackberry Valley Residential Waste and Recycling Center at no tipping fee, and boulders are available at no cost from Twin Chimneys Landfill. The project's Notice to Proceed is contingent on pending permit approvals, with the estimated timeline set for November 2024.
