What You'll Learn
Industrial stormwater permit dischargers
The Santa Monica Bay Watershed Management Area (WMA) covers 414 square miles and includes the cities of Los Angeles, Santa Monica, El Segundo, Manhattan Beach, Redondo Beach, Palos Verdes Estates, and Rancho Palos Verdes. The WMA includes several watersheds, with the two largest being Malibu Creek in the north and Ballona Creek in the south.
The Santa Monica Bay watershed is subject to a variety of pollutants, including those from industrial stormwater permit dischargers. There are 85 dischargers enrolled under the general industrial stormwater permit in the watershed, with the largest numbers located in the cities of Los Angeles and Santa Monica within the Ballona Creek Watershed. These businesses are involved in electric, gas, and sanitary services; local and interurban passenger transit; and fabricated metal products.
The permit requirements for industrial stormwater discharges aim to control and reduce the impact of these pollutants on the watershed. The permit prohibits non-stormwater discharges into the watershed and requires the implementation of treatment control measures and programs to comply with waste load allocations. Regular inspections of commercial facilities are also mandated.
To further enhance watershed management, permittees can develop an Enhanced Watershed Management Program (EWMP). This involves collaborating with other partners to retain all non-stormwater and stormwater runoff, while also achieving benefits such as flood control and water supply. EWMP groups have been formed within the WMA, including the North Santa Monica Bay Coastal Watersheds, Santa Monica Bay Jurisdictions 2 & 3, and the Malibu Creek Watershed Group, among others.
The City of Santa Monica has also taken initiatives to reduce pollutants entering the bay. Measure V, passed in 2006, raises property tax revenue to fund urban runoff water quality improvement projects. These projects aim to prevent unhealthy water pollution from reaching Santa Monica beaches and the bay.

Bacteria indicators
The presence of bacteria indicators in the watershed is a result of various human activities and urbanization. The City of Santa Monica's storm drain system contributes pollutants, including bacteria, during both wet and dry weather conditions. High bacteria levels have been observed near storm drains, with rainfall worsening the situation. To address this issue, the city has implemented capital projects funded by "Measure V", which aims to improve urban runoff water quality and prevent pollution from reaching the bay.
The Santa Monica Bay Restoration Commission and the Santa Monica Bay Watershed Commission have been established to oversee the implementation of watershed management plans. These plans include monitoring programs that focus on assessing urban runoff effects along the coastline and in areas surrounding ocean outfalls. However, despite these efforts, bacteria indicators continue to be a problem in the watershed.
Heal the Bay, an organization dedicated to improving water quality, has conducted extensive research on the presence of bacteria indicators in the Santa Monica Bay Watershed. They have performed water quality testing at multiple locations within and outside the burn zone, including testing for Fecal Indicator Bacteria. Their findings have indicated high bacteria levels, particularly near storm drains, which can pose risks to both human and ecological health.
The Santa Monica Bay Watershed is also impacted by various other pollutants, including heavy metals, nutrients, and solids that decrease water clarity. Urbanization has played a significant role in the decrease of water quality, especially in riparian and wetland areas. The diverse nature of the watershed, encompassing both urban and rural areas, presents challenges in managing the various sources of pollution, including bacterial contamination.

Sediment toxicity
The Santa Monica Bay Watershed Management Area (WMA) is a 414-square-mile area that includes the city of Santa Monica and spans from the Santa Monica Mountains in the north to the Palos Verdes Peninsula in the south and the Griffith Park area in the east. The city of Santa Monica has been working to reduce the volume of pollutants entering the bay, as pollutants are deposited annually through the city's storm drain system during both wet and dry weather.
One of the key issues affecting the bay is sediment toxicity. Sediments in the bay have been found to contain high levels of contaminants, including DDT, PCB, copper, mercury, nickel, lead, zinc, and chlordane. These contaminants can have harmful effects on the environment and local wildlife. Marina del Rey Harbor and Ballona Creek Entrance Channel have been listed as impaired due to elevated levels of these contaminants in the sediment.
The sources of these contaminants are varied and include urban runoff, industrial discharge, and agricultural activities. Urbanization has significantly impacted the riparian and wetland resources of the watershed, leading to filling, alteration of flows, and decreased water quality. Contaminants from developed areas, such as Ballona Creek, are affecting water quality in the bay. Pesticides, fertilizers, oil and gas residue, litter, and pet waste are washed off by rainwater into storm drains and creeks, eventually flowing into the bay.
To address the issue of sediment toxicity, scientists have conducted studies to understand the distribution patterns of burrowing marine animals in relation to sediment toxicity results and the physical and chemical characteristics of the sediment. These studies help identify the sources and transport pathways of contaminants, as well as the habitats of bottom-dwelling organisms. Core samples from the seabed have also been dated using the radioactive isotope lead-210 to study historical contamination and track changes in contamination sources over time.
The City of Santa Monica has implemented projects funded by "Measure V," which raises property tax revenue to improve urban runoff water quality. These projects aim to prevent unhealthy water pollution from reaching Santa Monica beaches and the bay, ensuring compliance with strict pollution reduction regulations and avoiding potential fines.

Urban runoff
The Santa Monica Bay Watershed Management Area (WMA) is a diverse area that spans 414 square miles, from the Santa Monica Mountains in the north to the Palos Verdes Peninsula in the south, and the Griffith Park area to the east. The city of Santa Monica is part of this watershed and is working to reduce the volume of pollutants entering the bay.
To address this issue, the city of Santa Monica passed the Clean Beaches and Ocean Parcel Tax, also known as "Measure V," in 2006. Measure V raises property tax revenue specifically for implementing urban runoff water quality improvements. The funds are used for new urban runoff treatment projects that will prevent unhealthful water pollution from reaching Santa Monica beaches and the bay. The Public Works Department is responsible for implementing the Watershed Management Program and expending Measure V revenues on eligible projects, with approval from the City Manager, City Council, and an independent Citizen's Oversight Committee.
The South Santa Monica Bay Watershed, spanning 87 square miles, borders the Pacific Ocean and includes cities such as Redondo Beach, Marina Del Rey, Inglewood, and Carson. This watershed combines dense urban and residential areas with waterfronts, hills, and wetlands, and is home to over one million residents. The diversity of the watershed's natural features and cultural offerings makes it a lively and bustling area.
To mitigate the impact of urbanization on the watershed, the city of Santa Monica has completed capital projects funded by Measure V to reduce the amount of pollutants entering the bay. These projects include efforts to retain all non-storm water runoff and storm water runoff from the 85th percentile, 24-hour storm event, while also achieving benefits such as flood control and improved water supply. The city has formed several Enhanced Watershed Management Program (EWMP) groups, including the North Santa Monica Bay Coastal Watersheds, Beach Cities Watershed Management Group, and Ballona Creek Watershed Group, to collaborate on multi-benefit regional projects.

Pollution reduction regulations
The Santa Monica Bay Watershed Management Area (WMA) is a 414-square-mile region that includes both rural and urban landscapes. The watershed is bordered by the Santa Monica Mountains to the north, the Palos Verdes Peninsula to the south, and the Griffith Park area to the east. The WMA includes several watersheds, with the two largest being Malibu Creek in the north and Ballona Creek in the south.
Due to urbanization, the Santa Monica Bay watershed has been impacted by pollution, primarily through filling, alteration of flows, and decreased water quality. Pollutants enter the bay through urban runoff, which is influenced by both wet and dry weather conditions. To address this issue, the City of Santa Monica has implemented various pollution reduction regulations and initiatives as part of its Watershed Management Plan.
One key initiative is the Clean Beaches and Ocean Parcel Tax, also known as "Measure V," which was passed by voters in 2006. Measure V raises property tax revenue to fund urban runoff water quality improvement projects. These projects aim to prevent unhealthy water pollution from reaching Santa Monica beaches and the bay. The funds are used for constructing and installing devices to capture and treat stormwater and dry-weather runoff pollution, diverting stormwater to natural percolation areas, and building cistern systems for waste runoff reuse. Additionally, Measure V supports increased inspection and enforcement activities to catch polluters, as well as public education initiatives to raise awareness about the issue.
To comply with regulations and further reduce pollution, Santa Monica has also implemented a Citywide program that requires development and construction projects to incorporate specific design elements. These include the use of Best Management Practices (BMPs), Low Impact Development (LID) strategies, and good housekeeping practices. LID focuses on rainwater and stormwater management, utilizing retention BMPs and natural features to retain, infiltrate, store, or filter collected rainwater. The city also offers a list of acceptable post-construction BMP categories for LID, which is maintained and revised by the City's Office of Sustainability and the Environment (OSE).
Furthermore, the Los Angeles Regional Water Quality Control Board, the state agency responsible for protecting beaches and oceans from storm drain pollution, has enacted strict pollution reduction regulations for storm drains. These regulations aim to mitigate the impact of urban runoff, which is a significant contributor to ocean pollution and a threat to public health and water quality.
