Back to: About │ Master Plan 2022
LA County has a rich tradition of planning, as evidenced by the over 140 relevant adopted plans that were reviewed as context for updating the LA River Master Plan.
These plans span different geographic scales and topics and are the result of community-influenced processes. The LA River Master Plan leveraged the information from these plans as a foundation for understanding the river today and how it can be reimagined in the future (see Appendix Volume II, Technical Backup Document for full list of reviewed plans).
In addition to the 1996 LA River Master Plan, 11 other documents provided the most guidance for the LA River Master Plan update. The LA River Master Plan does not replace these plans. Rather, it incorporates the recommendations of these plans and provides an organizing framework within which LA County can comprehensively address the future of the LA River.
Common Ground from the Mountains to the Sea: Watershed and Open Space Plan San Gabriel and Los Angeles Rivers (2001)
Common Ground from the Mountains to the Sea imagines strategies and opportunities for creating a new public amenity along the LA River corridor, the San Gabriel River, and their tributaries. It proposes a continuous ribbon of open space, trails, active and passive recreation areas, and wildlife habitat.
Los Angeles River Revitalization Master Plan (2007)
The Los Angeles River Revitalization Master Plan (LARRMP) provides a bold vision for transforming the LA River within the City of Los Angeles over the next several generations. The plan acknowledges that great and transformative change may not be accomplished in one lifetime; it must remain in the minds of the people who will carry it forward. The plan for this stretch of the river includes four core principles: revitalize the river, green the neighborhoods, capture community opportunities, and create value.

The Long Beach Riverlink aims to provide residents with 1,100 acres of recreational open space, including pedestrian- and bike-friendly pathways, along the LA River while also restoring segments of the river back to native habitats and improving the aesthetics of the river and the city.
Stormwater Capture Master Plan (2015)
The LA County Flood Control District Stormwater Capture Master Plan (SCMP) inventoried existing and planned actions by LA Department of Water and Power, the City of LA, other city, county, regional, and federal agencies, and local non-governmental entities that impact stormwater. The SCMP is organized around the goals of quantifying stormwater capture potential and identifying new projects, programs, and policies to significantly increase stormwater capture for water supply within a 20-year planning period (2016-2035).
Los Angeles River Ecosystem Restoration Integrated Feasibility Report and its Recommended Plan (2015)
The Los Angeles River Ecosystem Restoration Integrated Feasibility Report and its Recommended Plan present potential alternatives for environmental restoration of 11 miles of the LA River that include the soft-bottom Glendale Narrows. The study analyzes the environmental impacts of implementing those alternatives, reviews the process for selecting the best alternative, and concludes with recommendations for project implementation.
Los Angeles Countywide Comprehensive Parks and Recreation Needs Assessment (2016)

The study models the impacts of implementing integrated water management practices in the LA River watershed, which address water quality and supply. The study also investigates the historical hydrology of the LA River and the impact of best management practices (BMPs) on runoff ratios.
One Water 2040 LA Plan Volume 4 – Los Angeles River Flow Study (2017)
One Water 2040 LA Plan employs a holistic and collaborative approach to managing water resources, which includes surface water, groundwater, potable water, gray water, wastewater, recycled water, and stormwater. One Water 2040 LA Plan Volume 4 is a study on low flow in the LA River. The study includes five water management concepts that optimize the amount of flow needed to support potential future water-dependent uses and satisfy regulatory requirements.1Current SCCWRP LAR Flow Study efforts to supplement LA’s vision of the LAR.

Lower Los Angeles River Revitalization Plan (2017)
The Lower Los Angeles River Revitalization Plan (LLARRP) describes opportunities for improving the environment and residents’ quality of life along a reimagined and revitalized river from Vernon south, and identifies and designs multi-benefit projects and policies to implement in the area around the river. The LLARRP addressed three broad goals: community economics, health, and equity; public realm; and water and environment.
Los Angeles County Annual Affordable Housing Outcomes Report (2019)
