A. Distances are measured horizontally. When determining distances for setbacks and structure dimensions, all distances are measured along a horizontal plane from the appropriate property line, edge of building, structure, storage area, parking area, or other object. These distances are not measured by following the topography of the land. See Figure 730-1.

Distances are always measured horizontally.

B. Measurements are shortest distance. When measuring a required distance, such as the minimum distance between a structure and a lot line, the measurement is made at the shortest distance between the two objects. See figure 730-2. Exceptions are stated in Subsection C, D and E.

Measurement is taken from the shortest Distance between the points.

C. Measurements of vehicle travel areas. Measurements of a minimum travel distance for vehicles, are measured down the center of the vehicle travel area. For example, curving driveways and travel lanes are measured along the arc of the driveway or traffic lane. See Figure 730-3.

Measure down the middle of the travel area.

D. Measurements involving a structure. Measurements involving a structure are made to the closest wall of the structure. Chimneys, eaves, and bay windows up to 12 feet in length, are not included in the measurement. Other items, such as covered porches and entrances, are included in the measurement. See figure 730-2 above, and the base zone sections.

E. Underground structures. Structures or portions of structures that are entirely underground are not included in measuring required distances. See Figure 730-4.

Measurements do not include underground structures
