[Added 3-11-2014 by Ord. No. 9048]
A. 
A residential cluster subdivision is designed to encourage a unitary site development plan for compact single-family and multifamily residential development. The concept of cluster development involves small minimum lot sizes on tracts of land developed as single entities for residential purposes. The cluster development regulations specifically encourage innovation so that the growing demands for housing may be met by greater variety in type, design and setting of dwellings and by the conservation of sensitive environmental area and more efficient use of land in general. The principal use of this district is for cluster housing.
B. 
The residential cluster subdivision district is to provide controlled development of closely spaced, residential buildings with individual design characteristics and appearances, flexibility in design and more variety in residential development.
C. 
The residential cluster housing district shall be used to promote development when one of the following property conditions exist on a portion of that property:
(1) 
Marginal environmental area: officially designated floodplains, subsidence areas and other areas deemed environmentally marginal;
(2) 
Transition area: where a demonstrated need exists to separate single-family dwellings from commercial or industrial establishments; or
(3) 
Other area: The Planning Commission may designate and approve other areas as residential cluster subdivision districts subject to the final approval of the City Council and consistent with good zoning and planning practices.
D. 
A residential cluster subdivision is designed to provide greater economy, efficiency and convenience in the siting of services and infrastructure, including the opportunity to reduce road lengths, utility runs, and the amount of paving required.
E. 
This district will provide more efficient allocation of parks, recreation areas and open space. In order to encourage more attractive site planning and building appearances, the controls provided for in the site plan requirements and subdivision requirements are flexible in nature. All structures within this district shall meet the minimum firewall regulations set forth in adopted City building and fire codes.
A. 
Residential cluster housing shall be used for the following purposes:
(1) 
Single-family and two-family dwellings.
(2) 
Accessory buildings and uses customarily incidental to the permitted uses.

(5) 
The following accessory uses, which are permitted as common facilities for the use or benefit of residents of the cluster subdivision as shown on the development plan:

All environmental marginal areas will be plainly delineated on the development plans and preliminary plat for residential cluster housing projects.
B. 
Transition area. Residential cluster subdivision projects shall be located on property which separates residential districts from commercial districts. A demonstrated need must exist for such a residential cluster housing separation between a single-family residential district and a commercial district.
