Continue measures to clean up the regional groundwater aquifers.

If water is diverted from the LA River to recharge groundwater, it could be used by municipal water suppliers during periods of greatest need. Identifying and cleaning contaminated groundwater aquifers is therefore crucial for augmenting local water supply.

Divert and treat stormwater and dry weather flows within the river channel for groundwater recharge, direct use as recycled water, and to supply water for parks and ecological areas.

Water diverted from the LA River could become another source in a portfolio of regional water sources. Diverted water could be used to enhance habitat, support recreation, or supply water for municipal and industrial uses. Storing diverted water in basins…

Capture and treat stormwater and dry weather flows before they reach the river channel for groundwater recharge, direct use, water recycling, or release for downstream beneficial uses.

The primary sources of water flowing into the LA River are wet weather (stormwater) runoff originating from precipitation on the watershed and dry weather inputs from the watershed, including incidental urban runoff and groundwater upwelling. The dominant source of dry-weather flow…

Repurpose single-use spaces, such as power-line easements, rail rights-of-way, or flood infrastructure, to serve multiple functions such as multi-use trails or habitat, and prioritize spaces that are in high and very high park need areas.

With little vacant land and relatively high property values and construction costs, LA County cannot afford to have spaces that serve only a single purpose. Multiple uses of space are necessary to ensure benefits outweigh costs.

Update and improve emergency preparedness.

Although flood infrastructure is in place to protect life and property, flooding can still pose a threat to communities within the floodplain during an extreme storm event. These communities, which are protected from routine floods, must still be prepared. The…
