Maricopa, AZ: Drainage clearance and a separate floodplain review

Maricopa Planning and Development describes drainage clearance for unincorporated areas and notes that designated floodplain projects may require an additional floodplain permit.

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: Sheet-flow changes can matter even without a constructed channel. Trace overland routes, retention and discharge limits to the accepted design before pricing walls or fill that could redirect runoff.
