Bruce Mowry, City Engineer reported on ongoing projects City staff is working on to address flooding.
The presentation reviewed projects Citywide and the effects that were being observed and how staff was
implementing solutions to reduce the impact of flooding. lt was reported that the two pump station
constructed at 1Oth and 14th Street were placed in operation on September 30th and had been running
continuously. The staff had seen dewatering in South Beach from not only on West Avenue and Alton
Road, but also in Flamingo Park on Meridian Ave. Water in the storm water collection systems on Euclid
had reduced levels to a point that gravity wells in the system had gone artesian and flowing up into the
collection system. lt was also reported that two of the rebuilt storm water pump stations were placed in
full operation in Sunset Harbour and that Pump Station No. 3 on 20th Street was nearing completion.
Temporary pumps and plugs installed in Sunset Harbour were being utilized to prevent flooding. David
