Existing Conditions
The existing storm sewer capacity is insufficient. In addition, there are no safe overflow routes on West Ellis and through homes on East Ellis and Sandstone Drive.
Proposed Improvements
Construct new floodwater storage basin (1.5 ac-ft) at the western end of W. Ellis Avenue to drain the existing depressional area. Install a new storm sewer from the proposed storage basin to the new and larger E. Winchester Road storm sewer system extending all the way to new outfall pipe at the north end of Lake Minear. Disconnect the east existing storm sewer system from new west system. Install a new storm sewer along Sandstone Drive and connect into the existing system going north.
Proposed Improvements - Alternate
Construct a new floodwater storage basin (1.5 acre-feet) at the eastern end of W. Ellis Avenue to drain the existing depressional area. Install a new storm sewer from the proposed storage basin to the new and larger E. Ellis Avenue storm sewer system following the alignment of the existing storm sewer. This new sewer alignment will then extend southward along Sandstone Drive and out to Lake Minear through an easement(s) to be obtained from a private property owner(s).
Project Cost: $5,176,560 (2018 Dollars)
Project Cost - Alternate: $4,445,940 (2018 Dollars)
