Witch Fire Orosco Road Crossing Replacement

Added: Mar 25, 2016 12:53 pm The objective of this contract is to provide replacement structures within the existing roadway on Orosco Ridge Road (12S02) located on the Palomar Ranger District (PRD) of the Cleveland National Forest. Additionally the contract will include associated stream channel restoration work above and below each structure. The structures have been sized to accommodate both stream simulation and the design storm flows. The work to be done includes the procurement and installation of two 16 foot span by 16 foot wide prefabricated concrete bottomless arch culverts with head walls, wingwalls and associated buried rip rap along the culverts and wingwalls. The structure footings will be of cast in place reinforced concrete. Additional fill material will be placed to raise the approach road to and from these structures and the asphalt paving required to tie the approaches into the existing road. Any rip rap that was installed as part of the original road/stream stabilization process may need to be removed to accommodate plan geometry and elevations. It will be reused as part of the new constructed fix. The stable stream channel elevations will be re-established, per plan, as part of the repair.
This contract provides for the equipment, labor, materials, and services necessary to perform all the work described in the above statement and in compliance with the terms, specifications, drawings and provisions of this contract.
