Pinal, AZ: Preliminary and final drainage clearance are separate milestones

Pinal County’s published drainage ordinance distinguishes preliminary and final drainage clearances and also addresses grading and clearing/grubbing permits. The reference identifies several approval milestones rather than a single release.

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 treat preliminary drainage clearance as a complete construction release. Quantify the accepted final layout and retain unresolved grading conditions as bid clarifications.
