Current Projects from ULAR WMG

The County of Los Angeles, in partnership with the Cities of Alhambra, Monterey Park, Pasadena, Rosemead, San Gabriel, San Marino, South Pasadena, and Temple City are finalizing a project concept for the Rio Hondo LRS Implementation Project. This project would divert and treat dry-weather flows from a 35,000-acre tributary area in the Rio Hondo watershed.

The Rory M. Shaw Wetlands Project will convert a 46-acre inert, construction debris landfill to a wetlands park facility to provide enhanced water quality, flood protection, habitat creation, groundwater recharge, and recreation. A storm drain system will collect stormwater runoff from the upstream 929-acre drainage areas and convey to the project site with a detention capacity of 400 acre-feet.

The objective of the San Fernando Regional Park Infiltration Project is to divert and capture urban runoff from 942 acres of land and address discharges from within the City into Pacoima Wash and the Los Angeles River. The runoff will be diverted for pre-treatment, conveyed to a subsurface storage system, and released into the ground for infiltration.
