Lonesdale Place Drainage Improvements

As part of DRMP’s Professional Miscellaneous Engineering Services for Stormwater and Environmental Services continuing contract with Hillsborough County, DRMP provided drainage improvement solutions to the flood-prone roadway of Lonesdale Place.

DRMP provided professional engineering services for design and permitting of a new 30-inch outfall pipe along Silverhill Drive to convey stormwater to Northdale Boulevard and alleviate roadway flooding.   A weir was designed into the new outfall pipe to maintain the historic wetland elevation.   This was done to maintain the hydroperiod of the existing wetland.   The new outfall pipe effectively conveys runoff away from the flood-prone area.
