Orange, CA: WQMP permanent practices versus ESCP construction measures
Orange County distinguishes the project-specific WQMP for permanent post-construction BMPs from the ESCP submitted with grading and building plan checks.
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: Use separate workbook groups for permanent treatment and temporary erosion measures. Reconcile changes between grading and building submissions so repeated ESCP sheets do not duplicate installation quantities.
Check the project documents
Clarification to request: Which BMPs are temporary, which are permanent, and when does maintenance responsibility transfer?
