Post-Construction Information

Post-Construction Site

Best Management Practices


To lessen stormwater impacts from new developments, best management practices to treat, store, and infiltrate water onsite before it can affect water quality downstream can be used. Examples of post-construction best management practices include Low Impact Development, grassed swales, and bioretention.

Objectives


The objectives of Maricopa County's Stormwater Quality Management and Discharge Control Regulation (PDF) include protecting water quality to the Maximum Extent Practicable by removing and/or treating pollutants prior to discharge and promoting long-term operation and maintenance of all permanent stormwater management facilities.

Permit Requirements


Post-construction design should incorporate permanent structural and/or non-structural best management practices and long-term operation and maintenance responsibilities. For submittal requirements and applicable fees, please refer to the Post Contruction Application or the Fee Schedule page.


Standards


Standards for post-construction design and maintenance can be found in the Drainage Policies and Standards Manual for Maricopa County (PDF).
