|
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.

Statement Of Intent And Purpose. The "RA-5" Rural/Agricultural
District is established to provide areas for agricultural uses, very-low-density
residential development and minimize the premature development of

A.
Statement Of Intent And Purpose. The "R-7" Single-Family
Residential District is established to provide single-family residential
development with a density that is typically referred to as urban
in nature. The "R-7" density supports the goal of the Official Master
Plan by providing single-family densities at a maximum of five (5)
dwelling units per gross acre. This district is designed to allow
for the orderly extension of urbanized development. The purposes and
intent include the following:
1.
To provide for residences that are served by urban type services
and that have a high degree of access to adequate transportation systems.

To promote an efficient pattern of development.
|
|
Accordingly, the following conditions should be present to support
an "R-7" zone district for a site:

A.
Statement Of Intent And Purpose. The "PR-1" Planned Single-Family
Residential District is established to provide single-family detached
dwellings at higher densities than "R-7" will allow in consideration
of providing more usable open space or specific amenities. The "PR-1"
District is intended to promote variations to the standard single-family
environment, i.e., patio homes, cluster homes and zero (0) lot line
placement all in keeping with the detached dwelling environment through
the establishment of more common ground/open areas. This district
is designed for areas served by centralized utilities.

A.
Statement Of Intent And Purpose. The "PR-2" Planned Mixed
Residential Use District is established to provide opportunities for
high-density mixed residential use development from single-family
to multi-family dwellings units with a variety of formats and densities.
The plan for this district should be designed to create a transition
from more intense mixed uses to less intense mixed uses. While providing
for a wide range of dwelling types, the "PR-2" District may also be
appropriate in large scale mixed use developments. This district is
designed for areas served by centralized utilities.
B.
Uses. Permitted principal and accessory uses, uses permitted as of right but with conditions and conditional uses are contained in Table 5-1 in Section 400.1650.

The purposes and intent include the following:
1.
To provide sufficient space in appropriate locations for neighborhood-oriented
commercial services and products.
2.
To provide for non-residential areas where traffic generation and
the size of use may be appropriate for locations near concentrations
of residential uses.
3.
To protect adjoining uses from fire, noise, glare and other similar
impacts.
4.
To protect logical neighborhood commercial areas from impacts such
as high traffic volumes, noise and vibration.

D.
Performance And Design Standards.
1.
Design standards are applicable to development in this district. All development must be in accordance with suburban or mixed use design standards. (See Section 400.2170.) The Official Master Plan shall serve as a guide to which design standards apply in a particular development pattern.
5.
Neighborhood-oriented office development that generates pedestrian
activity shall be located on ground-floor levels in the "NC-1" District.

instrument may be used and measurement may include breakdowns into
a reasonable number of frequency ranges. All noise shall be muffled
so as not to be objectionable due to intermittence, beat frequency
or shrillness.
c.

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.

Industrial District is established and designed to promote intensive
commercial or light industrial development in areas with an appropriate
level of accessibility and separation from incompatible uses. This
district is also designed to promote and protect the health, safety,
morals, convenience, order, prosperity, and other aspects of the general
welfare. The purposes and intent of the "NPI" Non-Planned Industrial
District include:
1.
To provide sufficient space in appropriate locations for intensive
uses that would be undesirable close to residential and community
oriented uses.
2.
To accommodate a higher intensity of traffic generation in an
appropriate location remote from residential and general retail areas.
3.
To protect logical light industrial uses from adverse impacts
such as noise, vibration, and traffic associated with general retail
and heavier industrial uses.
4.
To provide for a distinct designation appropriate for low to
medium intensity industrial uses that are not required to be specified
and approved as part of a development plan.
B.
Uses. Permitted principal and accessory uses, uses permitted as of right but with conditions, and conditional uses are contained in Table 5-1 in Section 400.1650.
