(OCTA). This program makes funds available to soliciting cities to help protect Orange County beaches and waterways from transportation-generated pollution and improve overall water quality.
The project collects drainage from a total of 196 acres composed of commercial, manufacturing, industrial, bus stop locations, multi-family homes, and single-family residences 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) 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 Chapman Avenue approximately 100 feet west of Eckhoff Street. The proposed connector pipe screens (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 13 catch basins on Chapman Avenue, Katella Avenue, Main Street, and Brian Street.
The total project cost is estimated at $370,000, 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, if necessary, and award of contract.
Construction is scheduled to begin in September 2023 and is expected to be completed by October 2023.
Specifications and cost estimates are available for review in the Public Works Department.
7. ENVIRONMENTAL REVIEW
Categorical Exemption: The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) per State CEQA Guidelines Section 15301 “Existing Facilities” Class 1 and Section 15308 “Actions by Regulatory Agencies for Protection of the Environment” Class 8 because the project involves installation of storm water treatment features to the existing storm drain system and does not increase system capacity or otherwise expand the existing use. No public review is required.
The CEQA Notice of Exemption will be filed with the County Recorder’s Office upon Council’s approval of the plans and specifications.
