Maintenance of Northwestern Basin Rehabilitation (L02P22)

The Maintenance of Northwestern Basin Rehabilitation project, identified as solicitation PP-25-0204, involves the rehabilitation of the Northwestern Basin located in the Las Flores Unincorporated Area of Orange County, California. Managed by Orange County Public Works and OC Construction, the scope of work includes the removal and replacement of a damaged CMP riser and existing rip rap, the installation of grout from the access road to the riser and into voids under the existing pipe, and the clearing of vegetation from the concrete turn-around pad. Additionally, the project requires the inspection and clearing of blockages in the retaining wall weep holes and the implementation of Best Management Practice measures. The project is classified as a forecast under NAICS code 237990 and is exempt from CEQA under Section 15301 Class 1 for the repair and maintenance of existing public facilities. Construction is expected to last approximately five months, with an anticipated completion date in the Spring of 2027. Logistics are expected to be minimal, with approximately eight construction truck trips and no traffic impacts due to onsite staging. Key project personnel include Project Manager Diane Hernandez and Senior Planner Virginia Gomez.
