The following situations are exempt from the Oak Tree Permit requirements:

If the subject property is within a Homeowners Association area, the applicant shall submit their tree removal plans to the Architectural Review Board of said Homeowners Association for review and approval, conditional approval or denial, prior to filing an application with the City.
