4. Project Description The Project will divert stormwater from a 45” storm drain into an underground infiltration gallery to infiltrate into the San Fernando Groundwater Basin. The area is owned by Los Angeles Department of Recreation and Parks, but is not developed for park users. The Project will include new park amenities at the 2.3-acre affected site.

5. Project Description • Tributary Area: 485 acres • Approx. Yield: 294 AFY • Approx. Affected Area: 2.3 acres • Benefits: • Increase local water supply • Improve downstream water quality • Provide community driven park development • Raise public awareness

6. Project Outreach • Outreach meetings will be held at the appropriate Council District and Neighborhood Council throughout the design and construction phase to solicit community input and feedback. • Public meetings specific to the environmental process will be held, if necessary. • Construction Notification Mailers will be sent to neighboring residents. • Planned long-term project messaging: • Project will be highlighted on the Department website with details and updates on the environmental process, communication efforts, schedule and funding.

7. Funding Details Funding: • Total Project Cost: $18,434,000 • Matching Funds (Amount and %): 16,934,000 (92%) • Grant Request: $1,500,000 • Matching Funds Sources (specify which are state funds): LADWP, Measure W (Potential), Caltrans (State, Potential) • O&M costs per year: $14,300 Partners: LA Dept. of Public Works. LA Dept. of Recreation and Parks, and Caltrans

8. Program Preferences • Climate Change Response: Potentially increase the region’s local water supply by 294 AFY, reducing the region’s dependence on imported water supply. This also contributes to regional water self-reliance. • Statewide Priorities Objectives: Drought Preparedness, Use and Reuse Water More Efficiently, Climate Change Response Actions, Practice Integrated Flood Management • Expected Useful Life: 40 years • CEQA and Permit Completion Estimated Date: Dec 2020

9. Benefits • Current Conditions: Approximately 2.5 acres of land consists of tall, dry shrubs and is not utilized by park users

10. Benefits • Future Conditions: LADWP is working with the park owner and project designer to implement new park amenities at the proposed site. Outreach will be done as well to inform and solicit feedback from the community. • Other Physical Benefits: The project is estimated to yield 294 AFY to increase the region’s local water supply. This was determined using the EPA’s Storm Water Management Model (SWMM), a dynamic model that is able to simulate rain events.
