The project collects drainage from a total of 354 acres composed of commercial, bus stop locations, light manufacturing, industrial manufacturing, multi-family homes, and single-family home sections of Orange. These areas combine to generate potentially significant amounts of leaves, trash, and other debris. The City has looked at various options to control trash and debris. Through the Orange Municipal Code, the City can enforce sections related to littering and nuisances and its weekly street sweeping program picks up a large amount of trash and debris; however, anything not collected by the street sweepers has the potential to enter the storm drain system and impact the downstream water bodies. The proposed Debris Separating Baffle Box (DSBB) is a Continuous Deflection Separator (CDS) unit and helps address this deficiency by capturing trash and debris and other gross pollutants via its trash screens, sediment chambers, and the use of an oil skimmer and hydrocarbon boom filters. The DSBB will be placed on Taft Avenue just east of the Taft Avenue/O’DonnellWay intersection. The proposed connector pipe screen (CPS) units also help solve this deficiency by capturing trash and debris and other pollutants within each catch basin. The CPS will be installed in seven (7) catch basins on Taft Avenue, and Lewis Street.
The total project cost is estimated at $530,000, including 5% for construction engineering and 10% for contingency. Upon receipt of public bids, staff will return to the City Council and recommend any funding adjustments and award of contracts.
The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) under CEQA guidelines Section 15301 “Existing Facilities” Class 1. The CEQA Notice of Exemption will be filed with the County Recorder’sOffice upon Council’sapproval of the plans and specifications.
Construction is scheduled to begin in May 2023 and is expected to be completed by October 2023.
Specifications and cost estimates are available for review in the Public Works Department.
