Arcade Creek Park Preserve Restoration Project

Creek restoration in the Arcade Creek Park Preserve involves creek bank terracing and stabilization and eucalyptus and Himalayan blackberry removal. Re-contouring of creek banks to reduce slopes and application of biotechnical treatments will be implemented to limit future erosion. Replanting of natives will follow eucalyptus and blackberry removal to further stabilize banks as well as enhance habitat.

Three priority restoration sites have been identified through initial site reconnaissance undertaken by Foothill Associates and cbec. Additionally site restoration of priority site 3 will involve creation of a stabilizing grade control/step pool system on a drainage tributary to the creek. New hydrologic and hydraulic models will be developed from the existing SacCalc and HEC-RAS models of the creek existing conditions provided by Domacelli and Associates. The existing condition hydraulic/hydrologic models will be used to provide design parameters such as depth, flow, velocity, and bed shear stress for statistically relevant flow events.

Specific technical tasks to be undertaken by cbec include:

  • Hydrologic study/hydraulic modeling of existing conditions
  • Site channel surveys at the three priority locations
  • Development of 50%, 90%, and final construction documents
  • Construction services
