Puente Hills Transfer Station & MRF

Designed to meet the growing municipal solid waste needs of the County of Los Angeles, this transfer station and materials recovery facility (MRF) has the capacity to process 4,400 tons per day. The main building, at 215,000 square feet, is large enough to accommodate three football fields and has a 300 foot clear span with a vertical clearance of 55 feet. Six below-grade truck load-out positions provide for trash transfer to off-site landfills. Also inside the main building is the MRF, where recyclables are sorted and baled before being shipped from a loading dock.

The three-story administration building includes an atrium lobby and bridge gallery for visitors to enter the main building and view the daily MRF and transfer operations from overhead. The 25 acre site also includes scale facilities, a fueling station, and a truck maintenance building. 

JRMA’s design situated this massive building on an existing site, creating a look that complements the surrounding structures and ensuring smooth traffic flow for incoming and outgoing vehicles.
