A conditional use master plan is a plan for the future development of a use that is subject to the conditional use regulations. An approved master plan is intended to ensure that you will be allowed to develop in a manner consistent with the approved plan.
The master plan must include proposed uses and possible future uses that might be proposed for at least 3 years and up to 10 years. An approved master plan remains in effect until development allowed by the plan has been completed or the plan is amended or superseded.
Master plans may be completed at varying levels of detail. Generally, the more specific the plan, the less review that will be required as the future uses and developments are built.
