About this file
This attachment document consists of orthophoto unit maps and topographic maps for Custer State Park in South Dakota, detailing five forest management bid items to be completed during Fiscal Year 2027. The project encompasses multiple treatment areas: Bid Item 1 addresses Needles Windstorm Fuels across eight units totaling 42.9 acres with a limb and scatter prescription; Bid Item 2 covers additional Needles Windstorm Fuels across four units totaling 54.0 acres with the same prescription; Bid Item 3 involves East Windstorm Fuels across two units totaling 28.1 acres; Bid Item 4 consists of Precommercial Thinning across two units totaling 87.7 acres with thin-from-below prescriptions targeting specific tree spacing (12 feet and 10 feet respectively); and Bid Item 5 encompasses the Four Mile Draw Mastication area totaling 26.2 acres with complete pine removal. Each map includes detailed location references, elevation contours ranging from 4,000 to 5,600 feet, resource roads (both active and abandoned), waterways, park boundaries, and highway access points via US Highway 16A, SD-87, and various local roads.
The maps serve as visual specifications for offerors preparing proposals for the forest management treatments, with detailed acreage breakdowns and unit designations enabling contractors to assess project scope and logistics. The precommercial thinning units provide specific silvicultural targets including pre-treatment tree per acre (TPA) counts and target post-treatment spacing, while fuel reduction and mastication units specify removal and scatter methodologies. These maps support the RFP #26RFP19892 issued by Custer State Park, allowing offerors to evaluate individual bid items independently and submit proposals for one or more treatments as needed for their forest health, wildfire fuel break restoration, and wildlife habitat improvement objectives.
