Urban Design & Public Infrastructure
Project: The Piggyback Yard Conceptual Master Plan
Location: Los Angeles, California
Client: Friends of the Los Angeles River (FoLAR)
Size: 125 acres
Web: www.piggybackyard.org

Facts:

  • The Piggyback Yard is one of the largest pote tial sites for water storage along the L.A. River
  • Sometimes known as the Mission Yard or the LATC [Los Angeles Transfer Container Facil- ity], the site is a 125 acre intermodal facility where containers are humped or piggybacked between flat cars and 18 wheelers, thus the nickname Piggyback Yard
  • Four Principles guide the master planning and design process:
    1. Water
    2. Open Space
    3. Connectivity
    4. Community
Challenge: This single-use rail yard and container transfer facility is the largest privately-owned contiguous tract of land in downtown Los Angeles with the poten- tial to mitigate potential flooding created by the reduced capacity of the L.A. River channel.

Solution: This ambitious plan for urban revitalization maintains the existing use while transforming a sea of asphalt into an efficient transportation center including mixed-use development, connections to public transit, an engineered naturalized 45-acre rehabilitated wetland, and stormwater detention basins, creating a total of 130 acres of open space. The design also transforms project technical require- ments into physical amentities, creating;

  • A thriving urban ecosystem by reshaping the concrete channel container into a constructed wetland.
  • The opportunity for natural water infiltration and cleansing.
  • Detention of 100 year flood event to help protect developments downstream.
  • Open space recreation amenity and miles of pedestrian trails.
  • Accommodates the proposed CAHSR alignment
  • Vital link and much needed open space for East LA communities
  • Impetus for development of mixed-use real estate
  • Site for rail maintenance and operations facility
