Section 503.00 - Low Density Residential Districts
(LDR-12,000, LDR-9,000, LDR-6,000)
[Last amended 8/13/98, Ord. 657]

The purpose of the LDR Districts is to provide for high-density rural residential development on selected
lands identified as Low Density Residential in the Comprehensive Plan. The LDR Districts are intended
to accommodate rural residential development in locations generally adjacent to urban centers and are
characterized by patterns of subdivision or partitioning creating a scale of service and access
requirements that are complementary or similar to city residential zones. Depending upon location, LDR
Districts may be converted in a timely and orderly manner through annexation to city residential lands.
The LDR Districts shall apply only to those lands zoned LDR at the time of adoption of this ordinance.
503.02 Permitted Uses
In the LDR Districts, the following uses shall be permitted subject to the standards and limitations
set forth in subsection 503.06:
