The Deer Hollow Subdivision had historically drained to the east to a large wetland on the north end of our clients property. The wetland on our clients property had increased significantly since the construction of I-75 in the early 1980s. The property owner to the north of our clients 60 acres had filed a complaint with the Sarasota County Department of Natural Resources because the wetland was expanding onto his property. Our client felt that the increased flow of stormwater from Deer Hollow Subdivision was causing the problem.
Minder & Associates Engineering Corporation first surveyed the wetland and obtain elevations and the horizontal limits of the wetland. Our firm then obtained historical aerials of the size of the wetland prior to construction of Interstate 75, which was significantly smaller than the wetland as it existed after the construction of I-75. We then staked the wetland as it existed prior to construction of I-75 and met with representatives of Sarasota County Department of Natural Resources and the South West Florida Water Management District and pointed out the problem which was that the natural drainage to the east had been blocked by the construction of I-75. We then negotiated a deal with them that the wetlands would be restored to the historically limits that existed prior to the construction of I-75 and that our client would construct a drainage ditch south along the frontage road (Brown Road) to Richardson Road where the stormwater would run east through a large culvert under I-75. The frontage road had been constructed as a haul road during the construction of I-75 and was just shell placed on an earth base course with asphalt on top of the shell and with no consideration taken into account for drainage ditches and stormwater flow.
Minder & Associates Engineering Corporation surveyed and cross sectioned the frontage road at 50 intervals south from the wetland to drainage culvert under I-75 a distance of approximately 1.5 miles.
Our firm then designed a drainage ditch on the west side of the frontage road from the wetland to the culvert under I-75 and obtained the necessary permits for construction of the ditch from the Florida Department of Transportation, Sarasota County Department of Transportation and the South West Florida Water Management District. The drainage ditch was designed to keep the water elevation in the wetland at the historic elevation that existed prior to construction of I-75.
Our firm then worked with our client to select the construction contractor for the improvements and provided construction staking, construction administration and review of monthly pay estimates by the contractor.
Our firm then prepared the as built drawings and prepared the certificates for completion to all of the regulatory agencies.
