Daily Flood Situation Report May 5

Region 1 Davis County Update The rip rap placed along the river bank on the evening of 5/3/23 to protect the WBWCD’s water line appears to be holding well, but there is 18 inches of additional erosion to the eastern portion of the river bank that isn’t armored. DCPW and WBWCD agreed to pool resources to continue the mitigation work 5/4/23. The plan is to stockpile rock and cement at a staging area under the Adams Parkway overpass so equipment operators have it readily available to place as needed. UDOT and RMP have both been notified of poetnail risks to their infrastructure and RMP inspected the site on 5/3. South Weber and Unitah cities are also both coordinating. The Centennial Trail is closed to the public in this area and the WBWCD water line remains shut off as a precaution but no water users are without service, as they are back fed.
