6. Discussion and Background
The City of Orange Public Works Department applied for the Environmental Cleanup Tier 1 Grant Program managed by the Orange County Transportation Authority (OCTA). This is a competitive grant program for cities within Orange County. It helps to protect beaches and waterways from transportation pollution and to improve water quality. The City has been awarded $436,000 for installing a hydrodynamic separator, connector pipe screen units (CPS), and full trash capture (FTC) units.
The project collects drainage from a total of 214 acres composed of commercial businesses, bus stop locations, light manufacturing, industrial manufacturing, recreational open space, multi-family homes, and single-family homes. These areas combine to generate potentially significant amounts of leaves, trash, and other debris. The City has reviewed various options to control trash and debris. Based on the Orange Municipal Code, the City can enforce littering, nuisances, and weekly street sweeping program. 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 hydrodynamic separator is a Continuous Deflection Separator (CDS) unit. It helps to address this deficiency by capturing trash, debris, and other gross pollutants via its trash screens, sediment chambers, and the use of an oil skimmer and hydrocarbon boom filters. The CDS unit will be placed on Glassell Street, north of Brentwood Avenue. The proposed connector CPS units and FTC units also help to address this deficiency by capturing trash, debris, and other pollutants within each catch basin. CPS units will be installed in 11 catch basins and FTC units will be installed in two grate inlets on Glassell Street and La Veta Avenue.
The total project cost is estimated at $575,000, including 5% for design and 15% for construction engineering and contingency. Upon receipt of public bids, staff will return to the City Council and recommend any funding adjustments and award of contracts.
Construction is scheduled to begin in August 2024 and is expected to be completed by February 2025. Specifications and cost estimates are available for review in the Public Works Department.
7. ENVIRONMENTAL REVIEW
The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) per State CEQA Guidelines 15301 (Class 1(c) - Existing Facilities) 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.
