About this file
This document is an attachment to a federal contract opportunity that provides details on the clearing limits and brushing requirements for the PRD Mitkof Island Road Brushing contract.
The attachment outlines two methods for brushing the road - Method A requires clearing brush 5 feet beyond the ditch line and 10 feet on the fill slope, while Method B requires clearing brush within 5 feet of culvert inlets. The clearing height for both methods is 14 feet. The contractor is required to remove all debris from the road surface, ditches, and cut slopes, and ensure sufficient sight distance for sharp curves. The federal contract opportunity is a Request for Quotation (RFQ) to establish a Firm Fixed Price service contract for road brushing services on Mitkof Island in the Tongass National Forest. The contract period is from date of award until 31 August 2025, and this is a Total Small Business Set-Aside.
