Slope

Slope is a major factor when reviewing the town’s available landmass for development. Slope of the land is defined, as the change in vertical distance (height) over a horizontal distance i.e., 10 feet over 100 feet equals a 10% slope. The Antrim Town Slope Map shows four slope classes; these are:

• Flat-Lying Slopes:  These are slopes that would be described as flat to gentle slopes between 0 and 8%. These are generally the types of slopes that are most favorable to development because of the ease of site construction and development. Development in flat slope areas may be hindered by restrictions due to wetlands, poor soil/bedrock conditions, floodplains or Shoreline Protection areas.
• Moderate Slopes:  These are slopes that fall between 8 and 15%. These slope areas can be developed but at a greater cost. Costs due to steeper slopes are predominantly tied up in site design and initial construction.
• Steep Slopes:  These are slope areas that fall between 15 and 25%. These slope areas cannot be developed at this time without extraordinary means.
• Excessively Steep Slopes:  These are slope areas that are greater than 25%. These slope areas are generally considered not feasible for development, due to the costs of site work.
