What matters for project planning
Savannah maintains separate conveyance systems for household wastewater and rainwater; the city says stormwater flows to surrounding creeks, marshes, and rivers. Its original square plan dates to 1733, while island and west-side neighborhoods require a different coastal moisture and drainage lens than the Landmark District.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Verify each item with the City of Savannah and with the provider you ultimately choose before work begins.
