Document Description
The proposed project is the removal of the existing twin 42-inch corrugated metal pipe culverts that are failing with a 60-inch by 36-inch precast reinforced concrete box culvert. The current culverts and proposed replacement culvert length are both 36-feet long. The replacement culvert is sized for a 100-year storm. A trench will be cut through the pavement and roadbase to excavate the existing culverts, with equipment working from the roadway. The new culvert will then be placed in the trench in parts, assembled, and backfilled. Rock slope protection will be replaced within the existing footprint of the culvert to contain the backfilled material. Dewatering of the site will be required if water is present at the site during project activities. All construction impacts will be temporary and work will occur from the existing road prism.
