This document is a Pit Development Plan drawing for the Anderson Gravel Pit Rock Crushing project located in the Grand Mesa, Uncompahgore, and Gunnison National Forests within the Grand Valley Ranger District. The project is managed by the United States Department of Agriculture Forest Service, Rocky Mountain Region (R02), with a project date of 05/01/2026.

The plan establishes specific requirements for pit development and operations. Key provisions include: excavation limits must be flagged in advance by the Contracting Officer; stockpile areas require prior written approval; all slopes must not exceed 1:1 grade upon completion; clearing limits are shown on the pit development plan and will be specified on-site by the Contracting Officer; the top three (3) feet of soil overburden will be removed and stockpiled prior to crushing operations, with overburden subsequently spread evenly across all disturbed areas and seeded in accordance with specifications; and pit slopes must be sloped to drain between two (2) and four (4) percent from high point to low point based on existing site elevations. The plan includes a site map showing the proposed stockpile location, which will be designated on-site by the Contracting Officer, along with three reference photographs of the project area showing current conditions.
