Except as set out in this article, these regulations require a separate lot for each structure other than an accessory structure. To allow and encourage greater design flexibility for location for buildings comprising a planned group, the requirement for a separate lot for each building is waived and two or more buildings may be erected and maintained on the same lot only when certain conditions, as described in this article, are met.

(Ord. No. 533, § 2(21), 4-13-1999)

(a)

The following policy statement is in regard to the planned residential development provisions of the subdivision regulations in chapter 130:

(1)

It is intended to permit, on application and approval of detailed plans, creation of new higher density, single ownership residential projects where tracts suitable in location and character for the uses and structures proposed are to be planned and developed as units. Suitability of such tracts for the plans and development proposed shall be determined by the existing and prospective character of surrounding development, and by reference to the comprehensive plan.

(2)

In view of the substantial public advantages of planned unit development, it is the intent of this article to promote and encourage development in this form where appropriate in location and character.

(3)

Higher density, single ownership residential developments represent a special plan for a minimum of two and a maximum of six acres permitting the development of smaller building sites than otherwise permitted by this chapter and the subdivision regulations in chapter 130. Certain modifications of the general subdivision requirements are permitted when, in the opinion of the planning commission, adequate provisions are made for circulation, recreation, light, air and service needs of the tract when fully developed and populated.

(b)

Factors to be considered by the commission in review of planned residential development projects include:

(1)

Deed covenants for the development should include provisions for the maximum coverage of building sites and other design specifications in accordance with the provisions of chapter 130.

(2)

Deed covenants must include adequate provisions for the perpetual maintenance of common areas such as courts and playgrounds.

(3)

Plans for the development must include concrete curb and gutter streets, sidewalks, underground drainage, adequate spacing of structures to ensure access by emergency vehicles, and adequate off-street parking and access by residents. The planning commission may approve street rights-of-way of less than 50 feet in width with vehicular turnarounds of less than 100 feet in diameter, provided the street is no longer than 500 feet in unbroken length and, further provided that the proposed street is part of a cluster, townhouse, or condominium development according to specifications in chapter 130.

(4)

Consideration must be given to reservation of recreation space to serve the project's population. This required open space is in addition to other required open space and must exceed five percent of the gross area of townhouse, or condominium development.

(5)

Planned residential development projects will be required to follow subdivision regulation review procedures of sketch plan, general subdivision plan and final plat reviews as well as:

a.

Evidence of provision for operation and maintenance of such areas, improvements, facilities, and service as will be for common use by some or all of the occupants of the development, but will not be provided, operated, or maintained at general expense; and

b.

A preliminary traffic analysis indicating the probable effect of the proposed development on traffic patterns and capabilities of adjacent streets in the immediate area.

(6)

Other than the specific requirements listed above, planned residential development projects will comply with the general design and improvement standards of the subdivision regulations and this chapter.
