What matters for project planning
The City of Dayton's Department of Water, Division of Environmental Management, runs the city's Storm Water Management Program, established in 1997 to meet federal Clean Water Act permit requirements, and inspects hundreds of stormwater outfalls citywide each year. Because Dayton sits at the confluence of four waterways inside the Miami Conservancy District's flood-control system, parcel-specific flood status and drainage requirements should be confirmed with the city before foundation, grading, or exterior work begins.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
