The density requirements and locational characteristics of this urban residential district are a function of topographic conditions, such as slopes of over 15 percent, and/or other environmental constraints, such as soils, geology, and flooding, which restrict the carrying capacity of the land. This district provides for very low density, large lot single-family detached dwellings and duplexes, where such topographic conditions and environmental constraints occur.

In SFR-2, the minimum and maximum number of dwelling units (DU) permitted per gross acre, or fraction thereof, shall fall within the following range:

Minimum and Maximum Density Factor (df) . . . . . . . . 0.8 to 2.0 DU/gross acre
