The U.S. Army Corps of Engineers, Los Angeles District, has received an application for a permit for the Sand and Warm Creeks Confluence Improvements Project.
According to the Corps, the applicant, San Bernardino County Dept of Public Works proposes to convert approximately 2692 linear feet of the Sand Creek and Warm Creek from open, primarily soft-bottomed trapezoidal channels with earthen side slopes containing some revetment fencing, riprap and mixed rock rubble to open, trapezoidal channels with ungrouted rock and four grouted rock drop structures comprising all of the channel bottoms and ungrouted rock on all of the side slopes.
In total the proposed project would permanently impact 1.34 acre and temporarily impact 0.18 acre of non-wetland and wetland Waters of the United States (WoUS) for the purpose of providing 100-year flood risk management protection.
Construction of the project is estimated to be completed over a period of 1 year.
Deadline for sending comments on the proposed work is June 17, 2017.
