for the beginning of the transitional surface slope at any point along the lateral boundary of the primary surface , including the CZ , draw a line from this point to the runway centerline . This line will be at right angles to the runway axis . The elevation at the runway centerline is the elevation for the beginning of the 7:1 slope .

Incompatible Development Located in the Imaginary Surfaces at Seymour Johnson AFB Natural and manmade structures pose a potential safety concern for flight operations within Department of Defense established imaginary surfaces associated with Seymour Johnson AFB Runway 8 / 26 .
Compatibility Assessment Jurisdictions surrounding a military installation need to be aware of the various vertical obstructions and how they can impact the installation operations and missions . General development , towers , power lines , wind energy conservation systems or any other structures that are capable of causing incompatible development can ultimately threaten an installation ’ s day to day activity .
While jurisdictions within the JLUS Study Area have imposed height limits for zoning districts , there are instances where an increase in height limits are allowed by a conditional use permit ( CUP ) or a special use permit ( SUP ). There is a general concern that existing structures may be approved for height increases that would interfere with line of sight and aviation operations at Seymour Johnson AFB .
Incompatible development can include natural o within imaginary surfaces and in particular , the A Clearance Surfaces associated with the runways Figure 5.23‐2 shows the imaginary surfaces asso Seymour Johnson AFB runways and vertical obst is one obstruction which is a communication tow Horizontal Surface . This tower is 171 feet tall , ex for this surface by 21 feet .

The Agriculture District ( AG ) have an allowable maximum height of up to 35 f Institutional 1 District has an allowable maximum Office and Institutional 2 District does not have a maximum height . In all residential districts , the h may be increased by up to ten feet provided the front and side setbacks shall be increased by five
