Pacoima Headworks Natural Park is a proposed new project in partnership with the County of Los Angeles, the City of Los Angeles, and the Mountains Recreation and Conservation Authority (MRCA). 



The Pacoima Headworks Natural Park project envisions converting an underutilized, 3-acre publicly owned, restricted access parcel into a natural open space public park. The property is owned by Los Angeles County Flood Control District (LACFCD) and used to divert channel flows into the Pacoima Spreading Grounds. The site is currently fenced off from the public but can be viewed from the perimeter along Paxton Street and Arleta Avenue. This project will be a partnership between MRCA, the City of Los Angeles, and the County of Los Angeles. To date, the MRCA has had constructive discussions with the County to re-envision a portion of the Headworks area as a City of Los Angeles or MRCA developed natural park.

LA County Public Works has recently begun a three-year construction project to enlarge and enhance the Spreading Grounds, including to reconfigure and bury some of the infrastructure within the Headworks area making a future park possible. The Spreading Grounds improvements are planned to be completed by mid-2024 and will allow for a portion of the Headworks area to be re-envisioned to be publicly accessible open space. Potential improvements to consider include, but are not limited to: trails, shade trees, native landscaping, nature play, gathering area/outdoor classroom, stormwater feature, bioswales for stormwater treatment, smart irrigation, signage, and other amenities.
