CRESTVIEW-WOODLAWN DITCH IMPROVEMENTS JULY 11, 2025

_______ CONSULTANT’S INITIALS
SCOPE OF SERVICES
Based on an initial site visit with the City of North Augusta, the existing concrete-lined drainage
ditch behind the lots between Crestview Ave and Woodlawn Ave in the Bahama Heights
neighborhood has become severely eroded and is partially blocked with debris. After an initial
consultation with the City of North Augusta, Thomas & Hutton plans to help the City address the
issues through a ditch improvement project. The ditch improvement project would include
reshaping the portions of the channel to provide sufficient capacity and relining the channel with
concrete to provide for a stable, low-maintenance solution.
Figure 1 - Project Area Map
Thomas & Hutton has prepared the following scope of work to assist the City of North Augusta in
surveying, designing, permitting, and constructing the proposed ditch improvement project.
