| 説明 | Interceptor line relocation underway CORONA, Calif. — U.S. Army Corps of Engineers Los Angeles District Commander Col. Mark Toy participated in ground breaking ceremonies at the relocation of the Santa Ana River Interceptor line Oct. 11. The SARI line is a regional sanitary sewer line that serves Yorba Linda, east Anaheim, Orange, Santa Ana, Fountain Valley and portions of Garden Grove. According to the Santa Ana Watershed Project Authority, the SARI line was built nearly 40 years ago and was 20 feet below the surface. Decades of scouring and last year’s December storms threatened the line and required a reduced flow from Prado Dam and reinforcement by county workers at two locations to protect it. “Thanks to our partners, this work will have a significant impact along the course of the Santa Ana River Mainstem project,” said Toy.In support of the Mainstem project, Prado Dam’s flood basin has been increased by more than 140,000 acre-feet and river banks have been widened and strengthened below the dam to handle its new release capacity of 30,000 cubic feet per second, previously limited to 5,000 cfs.The SARI line’s new course will mostly parallel State Route 91. Where it has to pass under the river, it will be well below the calculated scour depth for the estimated operational life of the project, which is 100 years.As part of the ceremony participants got to sign a section of the 54-inch pipeline. Toy took the opportunity to endorse the project with the District motto, "Building Strong and Taking Care of People." |
