How did you measure the hard surface area on my property?

The city used low-altitude, high-resolution aerial photography to determine the hard surface area on each property. The city will perform aerial flyovers every three years to update the hard surface database.

Using aerial photography is the best possible way to measure each property’s individual hard surface area. However, mapping of aerial photographs does have a degree of inherent error. The hard surface area on each property was therefore reduced by 100 square feet to account for error in the measurements.

The image below is an example of aerial photography. The area outlined in blue represents the hard surface area. The pop-up block indicates the Billable Hard Surface Area of this property is 91,215 sq. ft.
