This step is optional. Step 2 Preliminary Plan Review (PPR) : A formal submission of the site plan for technical review. Required. Step 3 Final Plan Review : After the Preliminary Plans are approved the plans are submitted to Documents and Permits to pay fees and receive the Water and Sewer Availability Certificate (WSAC). Required. The applicant then continues through the DOB process.
