City of Temecula Flood Control Channel Reconstruction and Repair

Project Scope

CWE prepared schematic design drawings and cost estimates for reconstruction and repair of flood control channels adjacent to or running through Pala Community Park, Margarita Community Park, and Long Canyon Creek Park, in the City of Temecula. Tasks included: reviewing project plans and investigative reports, performing site review of existing facilities, hydrologic and hydraulic analysis of the creek systems, determining appropriate and cost-effective methods and materials to solve flood control channel erosion issues, preparing cost estimates, preparing schematic design of the preferred improvements chosen by the City, and seeking review and comment on the schematic design from resource agencies. The second phase of the project involves developing plans, specifications, and cost estimates; assessing jurisdictional delineation; evaluating environmentally sensitive areas and potential species that could be impacted; coordinating work with local native tribes; coordinating the geotechnical investigation; and preparing permit packages for approval by regulatory agencies.

Environmental Project Description
CWE prepared environmental services and schematic design drawings and cost estimates for reconstruction and repair of flood control channels adjacent to or running through Pala Community, Margarita Community, and Long Canyon Creek Parks. The second phase of this project involves evaluating environmentally sensitive areas and potential species that could be impacted. CWE prepared an Initial Study/Mitigated Negative Declaration (IS/MND) for aesthetics, agriculture and forest resources, air quality, biological resources, cultural resources, tribal cultural resources, paleontological resources, geology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, mineral resources, noise, population and housing, public services, recreation, transportation/traffic, and utilities and service systems. The IS/MND determined less than significant to no impact to all aspects of this phase. Additional tasks include: developing Plans, Specifications, and Estimates (PS&Es); assessing jurisdictional delineation; conducting focused biological surveys; coordinating work with local native tribes; coordinating the geotechnical investigation; a joint project review; and preparing permit packages for approval by regulatory agencies.
