Final Executive Summary, Master Facilities Plan & EIR/EIS
Geotechnical Investigation Program
As required by the Clearwater Program Master Facilities Plan and Environmental Impact Report/Environmental Impact Statement, which were approved and certified in November 2012, the Sanitation Districts of Los Angeles CountyÂ (Sanitation Districts) are in the process of implementing the Geotechnical Investigation Program along the future 6.9-mile-long tunnel alignment.Â The first of up to approximately 69 soil borings began on July 22, 2013.Â Click here for more information regarding the Geotechnical Investigation Program.
2013 National Planning Award
The Clearwater Program won the Grand Prize in the Planning Category of the 2013 Excellence in Environmental Engineering and Science Competition.Â This annual competition, begun in 1989 by the American Academy of Environmental Engineers and Scientists (AAEES) and judged by an independent panel of distinguished experts, recognizes public agencies, private companies, and universities throughout the United States whose projects exhibit a comprehensive, integrated, and innovative approach toward solving complex environmental problems.Â The Planning Category included facilities planning, preliminary engineering, and public outreach.Â Click here for more information regarding this award.
Overview of the Clearwater Program
The Clearwater Program is a comprehensive planning effort undertaken by the Sanitation Districts.Â Its purpose is to develop a long-range Master Facilities Plan (MFP) for the Joint Outfall System (JOS), a regional wastewater management system servingÂ nearly 5 million people in 73 cities and unincorporated county areas, including portions of the city of Los Angeles.
The Clearwater Program MFP evaluates infrastructure and facilities through the year 2050 and makes recommendations on how to maintain a reliable and cost-effective wastewater management system while increasing the use of a valuable resource, recycled water.
The MFP has identified the need for a new onshore tunnel and, possibly, a new ocean outfall to convey treated wastewater effluent from the Sanitation Districts' Joint Water Pollution Control Plant in Carson to the ocean. A new tunnel/ocean outfall would allow for the inspection and any necessary repairs of two existing effluent tunnels, which flow full every day and have not been inspected in over 50 years.
After evaluating over 50 potential project alignments, four feasible alignments were identified. The Sanitation Districts and the U.S. Army Corps of Engineers (Corps) analyzed the potential impacts of each of the four alternatives in a joint Environmental Impact Report/Environmental Impact Statement (EIR/EIS).Â
The draft EIR/EIS and draft MFP were released for public review in early February 2012.Â Three public hearings were conducted in early March.Â The public review period closed on April 10, 2012.Â Â Â Based on environmental considerations, public feedback, constructability, and cost, one alternativeâ€”consisting of a new 18-foot diameter, 7-mile long onshore tunnel only (no new ocean outfall)â€”isÂ the recommended project.
Availability of Final Documents
TheÂ Clearwater Program Executive Summary, MFP, and EIR/EIS have been finalized (see links below).Â The recommended alternative in theÂ final MFP andÂ final EIR/EIS is the same alternative that was originally recommended in the draft MFP and draft EIR/EIS.
