The equipment will be used to retrieve Large Woody Debris from debris basins, deck the material for later pickup, and process logs averaging up to 6 feet in diameter and stumps up to 12 feet in diameter into 6-inch or smaller wood chips. The contract will be awarded to the lowest-priced technically acceptable offeror based on the evaluation criteria. Quotes are due by 10:00 AM on June 27, 2025, with only ten days provided for proposal preparation.
