Staff is not currently available to walk-ins. There will be no Rapid Residential Review until further notice. 

Staff may be reached by phone or email and virtual meetings may be pre-arranged via email with the individual staff member. General planning and zoning questions for the Planner on Call may be emailed to If a virtual appointment is not possible, please review these guidelines and call 720-306-1606.
