Polk, IA: Runoff changes beyond new pavement

The stormwater provisions in the county’s published zoning ordinance address changes involving impervious cover, soil compaction, contours and drainageways, and groundwater dewatering or diversion. Review is not described solely in terms of paved area.

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: A staging pad or pumping operation can affect runoff without increasing final pavement area. Carry its proposed controls and restoration separately so temporary work is not lost in permanent drainage quantities.
