The project collects drainage from a total of 414 acres composed of commercial, hospitals, bus stop locations, Multi-family homes, Mobile Home Park, and Single-family home section 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 Tustin Street just north of the Santiago Creek. The proposed connector pipe screens (CPS) and the Full Trash Capture (FTC) units also help solve this deficiency by capturing trash and debris and other pollutants within each catch basin. The CPS and FTC will be installed in fifteen (15) catch basins on Katella Avenue, La Veta Avenue, and Main Street.
The total project cost is estimated at $627,200, 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 July 2022 and is expected to be completed by September 2022.
Specifications and cost estimates are available for review in the Public Works Department.
