Development Review Applications

The Planning Department's development review process begins with the Consolidated Development Application.

The Consolidated Development Application package consists of 3 basic components.  The first component is the General Application Form.  The second component is the Applicant/Property Owner Signature Form.  And, the third component is an applicable Supplemental Information Form for the type of application(s) proposed.  Additionally, there are Filing Instructions Handouts to aid an applicant to ensure their Development Application Form package is complete and contains all of the necessary components to process their application(s).  All the Consolidated Development Application materials can be accessed below. 

Planning applications may be submitted online through PLUS Online. Please see instructions for submitting online by clicking HERE.
