Construction, Inspections and Plats

  • Staff will review the documents and perform an inspection of the project site for compliance with all Post-Construction Ordinance (PCO) requirements including BMP installation.

  • Once compliance is confirmed, the BMP installation bond will be released and an As-Built Approval email will be sent to the design engineer.
