When a zone district from the current Zoning Order converts to a Planned District under the new UDO, dimensional regulations that existed in the Zoning Order will be applied to existing platted lots and site developments as the "planned" regulations for that development. The dimensional regulations would include setbacks, height, lot coverage and accessory structures. The regulations that applied at the time the development was approved will be the regulations that apply as the "planned district".
However, when a zone district from the current Zoning Order converts to a Planned District according to the conversion table above, lands not platted or without existing site development at the time the UDO is adopted by the County will follow the Planned District regulations.
**
Because the "PUD" districts include a wide variety of land uses and are a separate zone district, it was not possible to do a straight conversion of all "PUD"s into one (1) specific zone district of the new UDO. "PUD" developments will continue to be zoned as "PUD"s after adoption of the UDO with all of the conditions that applied at the time the "PUD" was originally approved. If at such a time, an owner/applicant wishes to rezone or ask for an amendment of the "PUD", the land will be rezoned into the applicable Planned District of the UDO. If the owner/applicant fails to take action on a preliminary plat/final master development plan of the "PUD", the preliminary plat/final master development plan shall expire in accordance with Article XVI.

The purposes and intent of the "PM" Planned Mixed Use District include the following:
1. 
Intent.
a. 
To allow greater flexibility in development standards (lot coverage, setbacks, building heights, lot sizes, etc.) to facilitate adaptation of development to the unique conditions of a particular site, while providing higher standards of site design and building design, a high level of environmental sensitivity and more satisfying living and working environments than can be achieved under the standards of other zoning districts.
b. 
To promote a streetscape that encourages buildings to be moved forward adjacent to the front yard setback line or adjacent to the required landscape improvements.
c. 
To encourage pedestrian friendly development.
d. 
Permit a mixture of uses that, with proper design and planning, will be compatible with each other and with surrounding uses or zoning districts.
2. 
Applicability. An area may be considered for rezoning to "PM" District if any one (1) of the following conditions exist:
a. 
More than one (1) land use or land use intensity is proposed for development on a single parcel, where only a single use is permitted under other zoning classifications; or
b. 
Different land uses that would not otherwise be permitted to locate within the same zoning district are proposed for development on one (1) or more adjacent parcels under single or separate ownership.
B. 
Uses.
1. 
Residential uses.
