About this file
These are technical construction drawings (detail sheets 840-2a) for an Alternate Overside Drain Fabrication for the United States Department of Agriculture Forest Service, specifically for the Los Padres National Forest in Monterey County, California. The three-sheet technical drawing set includes detailed fabrication specifications for three components: Headwall, Starter Attachment, and Flume, all to be constructed from 14-16 gauge galvanized sheet metal. Each sheet provides precise dimensional measurements, angle specifications, and design details for metal fabrication, with multiple views and cross-sections showing exact construction requirements for drainage infrastructure components. The drawings are part of a broader contract (Solicitation No. 127EAW25R0031) for Line Fire BAER and Suppression Repair, which involves replacing guardrail and repairing overside drains damaged during fire suppression efforts on the San Bernardino National Forest.
