Marion, IN: Drainage review does not remove floodplain review

Indianapolis states that development within a special flood hazard area requires a local floodplain development permit. Its drainage and infrastructure guidance treats floodplain obligations as relevant even when drainage permitting arrangements change.

Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.

What this changes in the bid review

Estimating interpretation: Do not infer that a change in the drainage application route removes the floodplain scope. Tie the measured grading surface to the applicable approval conditions and qualify unresolved fill or outfall assumptions.

Check the project documents

Mark each item after reviewing its supporting document.Check the parcel’s special flood hazard status with the responsible reviewer.Track drainage and local floodplain permit records separately.Identify approved conditions affecting fill, stormwater structures and access.
