More about the South Plain frame

Channel Characteristics

The channel in this frame is a trapezoidal concrete leveed cross section with an approximate width of 350 feet.

Landside Right-of-Way Characteristics

This frame has some of the widest right-of-way parcels along the LA River. The parcels are east and west facing parcels along the levee. The landside right-of-way is widest in the southern portion of the frame, at widths of over 200 feet on each bank. Industrial and residential development, transmission easements, and Interstate 710 and the 91 Freeway cut into the landside right-of-way in the northern portion of the frame. The landside right-of-way is on average 50 feet wide.

Notable Features

  • Important bird habitat area
  • Freshwater year round
  • Utility ROWs along both sides of the river
  • De Forest Park from river mile 6.8 to 7.5 along the left bank
  • Dominguez Gap Wetlands from river mile 4.8 to 5.8 along the left bank
  • Compton Creek confluence at river mile 5.4 along the right bank
  • LA River Trail provides recreational opportunities for pedestrians, cyclists, and equestrians

Significant Considerations

  • Significant equestrian community in this area would utilize an expanded network of equestrian trails.
  • Algae mats on the concrete channel bottom provide an important food source for migrating birds.
  • The widest portions of the landside ROW provides opportunity for significant habitat areas.
  • Utility ROW projects require further coordination with power companies, but also provide a significant amount of land for corridor connectivity.
