Announcement: New Development Applications!

Starting Monday, March 16, 2020, the Planning Department is beginning the implementation of a new Consolidated Development Application.

In order to streamline the Development application filing process with the County Planning Department, the previously used 45 development applications have been condensed down into a single Consolidated Development Application package.

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.  The third component is an applicable Supplemental Information Form.  And, as before, 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. New application materials can be accessed below. The Planning Department will continue to accept prior versions of the development application forms until futher notice.

Planning applications may be submitted online through PLUS Online. Please see instructions for submitting online by clicking HERE.
Solicitudes de planificación pueden enviarse en línea a través de PLUS Online. Por favor, consulte las instrucciones.
