Improving Water Quality
Program funds are allocated on a countywide competitive basis to assist jurisdictions in meeting the Clean Water Act for controlling transportation-generated pollution. The funds are designed to supplement, not supplant, existing transportation-related water quality programs.
Eligible applicants include Orange County city and county agencies such as planning departments, public works agencies, recreational departments, etc. Third parties, such as water and wastewater public entities, environmental resource organizations, nonprofit 501(c) environmental institutions, and homeowners associations cannot act as the lead agency for a proposed project; however, these agencies can jointly apply with a city and/or the County of Orange.
Two-Tier Grant Funding
In May 2010, the OCTA Board of Directors approved a two-tier grant funding approach to the program.
The Tier 1 Grant Program is designed to mitigate the more visible forms of pollutants, such as litter and debris that collects on roadways and in storm drains prior to being deposited in waterways and the ocean. Tier 1 consists of funding for equipment purchases and upgrades to existing catch basins and related best management practices (BMPs) such as screens, filters, inserts and other streetscale low-flow diversion projects. To date, $36 million has been awarded to 222 projects throughout Orange County.
The Tier 2 Grant Program consists of funding regional, potentially multi-jurisdictional, capital-intensive projects. Examples include constructed wetlands, detention/infiltration basins and bioswales, which mitigate pollutants including litter and debris, but also heavy metals, organic chemicals, sediment and nutrients. The Tier 2 program is funded with bond financing revenues with up to $38 million from the EAP allocated through fiscal year 2015-16. Beyond 2015-16, funding will be based on a pay-as-you-go basis. To date, two rounds of Tier 2 funding have been allocated. Approximately $28 million was awarded to 22 projects from 12 cities and the County of Orange.
