A variance shall be required for single-family homes or duplexes. A conditional use shall be required for all other uses. No application for variance or conditional use to the requirements of this Schedule may be considered by the Board of Adjustment or the Planning and Zoning Commission unless a copy of the application has been provided the airport manager of Orlando Sanford Intemational Airport for his review and advice as to aeronautical effects of the variance or conditional use.

Public and private interests and investments; c. The character of flying operations and planned developments of the airport; d. Federal airways as designated by the Federal Aviation Administration; e. Whether the construction of the proposed structure would cause an increase in the minimum descent altitude or the decision height at the airport; R-5 f. Technological advances; h. Land use density or intensit3r, i. The safe and efficient use of navigable airspace; j. The cumulative effects on navigable airspace of all existing structures, proposed structures identified in the Sanford Comprehensive Plan and all other known proposed structures in the area. C. Documentation Required. Each person applying for a variance shall submit documentation showing compliance with the federal requirement for notification of proposed construction and a valid aeronautical evaluation.
