Site plan review starts at the Planning and Development Department (PDD), which routes conceptual plans and other documents to the Water Services Department for review and comment before the pre-application meeting.

Privately funded projects are submitted to PDD, which collects all fees and then passes the projects on to the WSD for design review. All privately funded development and public Capital Improvement Program projects that are not in the public right-of-way must be reviewed by PDD for building code compliance.
