SEWER SYSTEM:
This project is to add 104 linear feet of gravity sewer collection line to the already
permitted and constructed sewer collection system under WQ 0028980 to serve an 11-
unit townhouse project. The permit modification also includes increasing the project flow
allocation from the already permitted 60 three -bedroom residences by adding 46 three -
bedroom residential units (16,560 GPD). Of the 46 units, 35 are existing and are already
connected and flowing into the permitted collection system. 11 of the 46 units are
proposed, and these will be reflected in the FTSE forms. The line extension will be
constructed by a developer and dedicated to the City of Southport for ownership,
operation, and maintenance.
