This is a proposal for a Preliminary Plan for the Rural Residential Planning Area within the RidgeGate Planned Development District, 7th Amendment. A Preliminary Plan is the first step in the subdivision process for single-family detached development. Preliminary Plans are intended to examine the feasibility of a single-family detached development project, and if approved, all future subdivision plats are required to be consistent with the approved Preliminary Plan. The RidgeGate Rural Residential (RR) Preliminary Plan proposes preliminary development plans for 261 residential single-family detached lots, roadways providing access to each lot, and numerous tracts for public parks, public open space, private open space, an amenity center, and utilities/infrastructure.
