Site development is the area of a property that is physically developed. It is typically the inverse of landscape surface area. Site development includes the area of the site is that covered by buildings, structures, impervious surfaces, porches, decks, terraces, patios, driveways, walkways, parking areas, and regularly disturbed areas such as corrals, outdoor storage and stockpiles. Even if a parking area or driveway is not paved, it will likely still count as site development. Site development does not include the cultivation of soil for agricultural use.
The definition of site development can be found in Division 9.5 of the Land Development Regulations.
Site development limitations on specific properties are based on zone and size of the lot. Reference the division of the LDRs for the applicable zone for the site development allowance formula.
