NARRATIVE
PROJECT DESCRIPTION
The purpose of this project is to develop a single family residential
subdivision with associated construction of paved streets, community water

development. The proposed development is located in Craven County
adjacent to the Neuse Harbour Subdivision off Neuse Harbour Blvd.
Approximately 3 acres will be disturbed during the construction phase of
this development. The total tract is 25.9395 acres. The total number of lots
proposed is 13, with the smallest lot being 26491 square feet (0.6081 acres),
and the largest lot being 208,745 square feet (4.7921 acres). All lots are
greater than 1/3 acre.
STORMWATER
This development will meet the criteria of a low density project. Stormwater
will be collected, treated, and transported via grass lined swales located
throughout the development as shown on the plan.
