As-needed catch basin maintenance services

City of Calabasas - Public Works has issued request for proposal, solicitation 2026-16.

The City of Calabasas (City) seeks to establish one or more contracts for maintenance and inspections of retrofitted catch basins. Catch basin cleaning may include debris/dirt removal, disposal and other clean-up activities associated with erosion, contaminants, excessive rain, vegetation, or other objects that fill catch basins and/or create blockages to the storm sewer system on an as-needed or emergency call-out basis/response. All the work will be performed in the public right-of-way (ROW). The resulting contract will be for a five (5) year term with up to two (2) optional one (1) year extensions.

The City of Calabasas has 573 catch basins which collect debris, particulates, and other items which may cause blockage of stormwater. The City performs an annual cleaning service for these catch basins with as-needed additional cleanings when storms or debris are heavier than expected at specific locations. A list of all catch basin locations is attached with the corresponding streets and coordinates listed.
