South Lyon City Zoning Code

ARTICLE XII

PLANNED UNIT DEVELOPMENT PUD OVERLAY

Sec. 102-150.- Purpose.

(a)

The planned unit development (PUD) standards are a supplementary list of "overlay" zoning standards which apply to properties simultaneously with one of the other zoning districts established in this title, hereinafter referred to as the "underlying" zoning district. For properties approved for PUD designation, these PUD standards replace the height and placement requirements listed for the underlying zoning districts in articles IV, V, residential districts, article VI, manufactured home park district, articles VII, VIII, commercial and office districts, and article X, industrial districts.

(b)

The PUD standards are provided as a design option, intended to permit flexibility in the regulation of land development; to encourage innovation in land use, form of ownership (such as condominiums), and variety in design, layout, and type of structures constructed; to achieve economy and efficiency in the use of land; to preserve significant natural, historical, and architectural features and open space; to promote efficient provision of public services and utilities; to minimize adverse traffic impacts; to provide better housing, employment, and shopping opportunities particularly suited to residents of the city; to encourage development of convenient recreational facilities; and to encourage the use and improvement of existing sites when the uniform regulations contained in other zoning districts alone do not provide adequate protection and safeguards for the site or its surrounding areas.

(c)

The standards are intended to accommodate development on sites with significant natural, historical, and architectural features, as noted in the city master plan, on land which exhibits difficult development constraints, and/or to provide the opportunity to mix compatible uses or residential types, and/or to allow clustering of residential units to preserve common open space and natural features. The PUD standards shall not be sought primarily to avoid the imposition of standards and requirements of other zoning classifications rather than to achieve the stated purposes herein set forth.

(d)

In order to encourage PUD developments on specific properties, these standards may allow the city to relax or waive one or more of the requirements of the underlying district. The PUD also allows the developer the opportunity to mix compatible uses or residential types on a single property, allows clustering to reduce construction costs, and may enhance marketability through the preservation of significant natural, historical, and architectural features.

Sec. 102-151. - Permitted uses.

Principal uses permitted under the PUD standards are based on the underlying zoning district, as indicated below:

(1)

R-1A, R-1, R-2, and R-3. All permitted uses of the underlying district shall be permitted. In addition to those uses, low density multiple-family dwellings or a mixture of single- and multiple-family dwellings on a planned basis, through the use of attached dwellings, townhouses, apartment buildings, zero lot line configurations, and/or other similar building configurations; or any combination of these residential uses may be permitted within the PUD.

(2)

RT, RM-1, RM-2, and RM-3. All permitted uses of the underlying district shall be permitted. The list of permitted uses includes multiple-family dwellings or a mixture of single and multiple-family dwellings on a planned basis, through the use of attached dwellings, townhouses, apartment buildings, zero lot line configurations, and/or other similar building configurations; or any combination of these residential uses. In addition, for sites having a minimum size of 20 acres, up to ten percent of the total site acreage may be developed with uses permitted in the B-1 district. Such uses must front a public street and be developed in conjunction with, or following, development of the residential uses.

(3)

CBD, GBD, O. All business, service, professional offices, and other commercial uses, or any combination of these uses, listed as permitted uses in the underlying zoning district shall be permitted. In addition, other business, service, office, and residential uses may be permitted, if determined by the planning commission to be compatible with other proposed PUD uses and surrounding uses.

(4)

I-1 and I-2. All manufacturing, warehousing, research and development, business, service, professional offices, and other industrial uses, or any combination of these uses, listed as permitted uses in the underlying zoning district shall be permitted. In addition, other business, service, and office uses may be permitted, if determined by the planning commission to be compatible with other proposed PUD uses and surrounding uses.

Sec. 102-152. - Special land uses.

All uses listed as special land uses in the underlying district are considered as special land uses within the PUD designation.

Sec. 102-153. - Qualifying conditions.

In order to qualify for PUD approval, the applicant must demonstrate in writing that each of the following criteria will be met by the proposed PUD:

(1)

Demonstrated benefit. The PUD shall provide two or more of the following benefits not possible under the requirements of another zoning district, as determined by the planning commission:

a.

Preservation of significant natural or historic features;

b.

A complementary mixture of uses or a variety of housing types that provides a benefit to the city over conventional development;

c.

Creative design that cannot be achieved by underlying district standards;

d.

Common open space for passive or active recreational use;

e.

Mitigation to offset community impacts;

f.

Redevelopment of a nonconforming site where creative design can address unique site constraints.

(2)

Availability and capacity of public services. The proposed type and density of use(s) shall not result in an unreasonable increase in the use of public services, public facilities, and utility capacities.

(3)

Compatibility with the master plan. The proposed PUD shall be compatible with the overall goals and recommendations as proposed in the city master plan.

(4)

Compatibility with the PUD purpose. The proposed PUD shall be consistent with the intent of this article and spirit of this title.

(5)

Development impact. The proposed PUD shall not impede the continued use or development of surrounding properties for uses that are permitted in this title.

Sec. 102-154. - Dimensional requirements.

(a)

Base zoning regulations. Unless modified by the planning commission, according to the PUD standards, all zoning ordinance requirements for the underlying zoning district shall remain in full force, except as modified by this article.

(b)

Regulatory flexibility. To encourage flexibility and creativity, the planning commission may grant specific departures from the requirement of the zoning ordinance as a part of the approval process. Yard, lot width, and bulk standards may be modified, provided that such modifications result in preservation of open space, enhanced buffering from adjacent land uses, screening along major roadways, preservation of natural features, a more efficient use of land or improved compatibility with adjacent land uses.

(c)

Approval of modifications. Any regulatory modification shall be approved through a finding by the planning commission that the deviation shall result in a higher quality of development than would be possible using conventional zoning standards. Regulatory modifications are not subject to variance approval of the ZBA. No part of a PUD plan may be appealed to the ZBA. This provision shall not preclude an individual lot owner from seeking a variance following final approval of the PUD, provided such variance does not involve alterations to open space areas as shown on the approved PUD site plan or the requirements of the article.

(d)

Table of modifications. A table shall be provided on the site plan which specifically details all deviations from the established zoning district's lot area, height and setback regulations, off-street parking regulations, general provisions, subdivision regulations or other zoning ordinance provisions which would otherwise be applicable to the uses and development proposed in the absence of this PUD chapter. This specification should include ordinance provisions, from which deviations are sought, and the reasons and mechanisms to be utilized for the protection of the public health, safety, and welfare in lieu of the regulations from which deviations are sought. Only those deviations consistent with the intent of this title and the city master plan shall be considered.

Sec. 102-155. - Application and review procedure for preliminary and final PUD site plan.

The application process for a PUD involves a three-step process including review of a preliminary site plan by both the planning commission and city council. Upon approval of the preliminary plan, a final site plan shall be reviewed by the planning commission. The procedures are described below.

(1)

The applicant shall meet with city staff to review the PUD requirements and confirm that application materials are complete.

(3)

The planning commission shall review the preliminary PUD site plan and shall conduct a public hearing in accordance with section 102-303. During this review, the planning commission may request additional materials supporting the PUD proposal, or recommend modifications or conditions based on the standards of section 102-156. The planning commission shall then make a recommendation on the preliminary PUD site plan to the city council. The applicant shall incorporate these modifications or conditions recommended by planning commission prior to the review by the city council.

(4)

Following receipt of the planning commission recommendations, the city council shall conduct a public hearing in accordance with section 102-303 on the preliminary PUD site plan. The city council shall take final action on the preliminary PUD site plan.

(5)

Any conditions imposed upon the approval of the preliminary PUD site plan by the city council shall be made part of the approval and shall be reflected in the final PUD site plan.

The applicant shall reimburse the city for all costs related to the preparation of the PUD agreement. The agreement, after approval by the city council, shall be entered into between the city and the applicant and be recorded in the office of the Oakland County Register of Deeds. The applicant shall pay all costs associated with recording the PUD agreement. The agreement must be recorded prior to submitting an application for final site plan approval.

(6)

Approval of the preliminary PUD site plan shall be effective for a period of two years. If a final PUD site plan for at least the first phase of the project is not submitted and approved within two years of the preliminary approval, the preliminary PUD site plan shall terminate and a new application must then be filed and processed. The two year period for preliminary PUD approval may be extended for not more than one year, if applied for by the petitioner prior to expiration and granted by the city council, based upon a recommendation by the planning commission.

(7)

If the approved preliminary PUD site plan indicated that the proposed development was to occur in phases, final PUD site plan approval may be granted on each phase of the development, provided that each phase contains all the necessary components to insure protection of significant natural, historical, and architectural features, and the health, safety, and welfare of the users of the PUD and the residents of the surrounding area. Roads, utilities and other infrastructure for each phase shall be designed to fully operate in accordance with city engineering standards and not be dependent upon the completion of subsequent phases. Subsequent phases shall also follow the process for final PUD site plans outlined in this article.

(8)

The applicant shall submit the final PUD site plan, as described in section 102-158, for all, or any phase of, the approved preliminary PUD site plan at least 30 days prior to the planning commission meeting at which the planning commission shall first review the request.
