Planned Unit Development District

Section 405.1360 Purpose Statement.

[Ord. No. 7020, 6-23-2026[1]]
A. 
The purpose of the planned unit development process is to foster appropriate use of existing buildings and enable compatible redevelopment which provides public benefits as identified in Section 405.1380 and achieves the following objectives:
1. 
Creation of a planned mixture of land uses while maintaining a more desirable environment through the combination and coordination of architectural styles, building forms, common facilities and buffers between uses;
2. 
Promotion of a creative approach to the use of land and related physical facilities resulting in better design and development, including aesthetics and public amenities;
3. 
More open space or natural resource protection than likely under as-of-right zoning;
4. 
Land use designs that incorporate natural terrain features, to preserve natural open spaces and desirable site characteristics such as restoration and maintenance of natural systems, native vegetation and geologic features;
5. 
Preservation of buildings which are architecturally or historically significant or contribute to the character of the City;
6. 
A greater mix of housing types and mix of residential and commercial land uses designed in a complementary manner to maintain community character;
7. 
Creating or contributing to neighborhoods that are more pedestrian and public transit-oriented;
8. 
Elimination of deteriorated structures or incompatible uses through redevelopment or rehabilitation; and
9. 
Implement the recommendations of the comprehensive plan.

Editor's Note: Former Article X, Planned Unit Development District, containing Sections 405.1360 through 405.1490, was repealed by Ord. No. 7020, 6-23-2026. Prior history includes: Ord. No. 6611; and Ord. No. 6753.

Section 405.1370 General Requirements.

[Ord. No. 7020, 6-23-2026]
A. 
A PUD is intended to provide a means for the redevelopment of an area in a unified land development that will improve the quality of the subject property and have a beneficial effect on adjacent properties.
B. 
Types Of PUD Districts. There are two (2) types of PUD zoning districts:
1. 
Residential. Rezoning to a residential planned unit development district is allowed only in areas where the existing zoning designation is residential and when:
a. 
One hundred percent (100%) of the gross square footage of the proposed buildings is to be used for residential purposes and/or open space regardless of the type of building in which such residence is located, i.e., conventional single-family residences, townhouses, duplexes, multi-family structures or apartments; and
b. 
The project is developed on a lot at least thirty thousand (30,000) square feet in size.
c. 
A residential PUD may be constructed on a lot measuring less than thirty thousand (30,000) square feet when such lot has an existing zoning of "M-3" High-Density Mixed-Use and when the proposed PUD measures at least fifty thousand (50,000) gross square feet and meets the single-use residential structure standards per Section 405.2870(E)(1)(i).
2. 
Mixed Use. Rezoning to a mixed-use planned unit development district is allowed only in areas where the existing zoning designation is non-residential or where the future land use designation is non-residential or mixed-use and when:
a. 
The proposed building(s) totals fifty thousand (50,000) gross square feet or more; and
b. 
The project incorporates two (2) or more distinct land uses; and
c. 
A mixed-use PUD must contain a reasonable ratio of areas devoted to distinct land use categories as determined by the City Council in the exercise of its legislative discretion. In determining the reasonableness of the areas devoted to district uses, the City Council may take into account the general character of the area within which the project site is located; the overall size of the project; the configuration of the proposed building(s) and the site layout; the need for non-residential services or a category of use in the area; and other factors which the Council finds relevant to such an analysis in a given case; and
d. 
The first floor of any mixed-use building shall include commercial land uses with public entrances to these uses from an adjoining street; non-residential uses are also allowed on other floors of a mixed-use building.
C. 
Minimum Project Standards. All PUD projects shall be designed to meet the following standards. Unless otherwise noted below, the minimum project standards shall not be eligible for modification through the PUD process.
1. 
Proposed developments shall meet the standards for LEED Silver certification or an equivalent standard as determined by the City Council. The project does not have to achieve actual LEED certification; however, the developer must submit the LEED checklist and documentation to the City as part of the application process, approved by a LEED Accredited Professional (LEED-AP), that shows that the project will comply with LEED Silver requirements.
a. 
Projects shall be designed to meet the latest adopted version of LEED as of the date of the application to the City.
2. 
Proposed developments shall be constructed with high-quality materials that add significant value to the property.
3. 
When designed for a Consumer Emphasis Area (CEA) use, the space shall meet the standards for retail ready including the following:
a. 
Minimum interior ceiling height for the CEA tenant space shall be fourteen (14) feet. This may be reduced to twelve (12) feet when measured from finished floor to a drop ceiling or similar feature used to create a corridor for mechanical, plumbing, or electrical infrastructure along the ceiling.
b. 
Service locations, connections, and corridors shall be identified for mechanical, plumbing, and electric for CEA uses. For food service uses, exhaust and grease trap connections shall also be identified.
4. 
Uses Allowed. All permitted uses in the existing base zoning district(s) shall be allowed unless otherwise specified in the PUD ordinance. Allowable uses shall be identified in the PUD document through a cross reference to applicable existing base zoning district(s).
a. 
Conditional Residential Uses. Dwelling units that require a conditional use permit in the existing base zoning district shall not be required to submit a separate conditional use permit, and approval shall be considered as a part of the findings and review of the PUD.
b. 
Conditional Non-Residential Uses. Non-residential uses that require a conditional use permit in the existing base zoning district shall not become permitted uses but shall remain conditional and allowed to commence and continue only with a valid conditional use permit.
D. 
Ownership. The tract of land to be developed as a PUD must be and remain under single ownership or control. The property included in the PUD shall be planned and developed as a single unit/phase.
1. 
Exception. Owner-occupied residential PUDs may be transitioned to multiple owners upon completion; however, the project shall still be constructed as a single unit/phase.
E. 
Plat Required. The planned unit development project shall consist of and shall be conterminous with a single lot described in a recorded subdivision plat.

1. 
Pre-Application Staff Meeting. Prior to applying for a PUD, the applicant shall participate in a pre-application conference with City staff. The purpose of the pre-application meeting is to allow City staff to review and provide comments on the suitability of the development concept as a PUD, as well as to provide guidance to applicant on the procedures and standards for PUD approval.
2. 
Conceptual Review. Conceptual review is recommended, not required, for PUD projects. This step allows for a non-binding presentation and review meeting with the Plan Commission, Architectural Review Board, and City Council before all project details are finalized. The public meeting provides opportunity for community feedback; however, options and issues raised may not be all-inclusive and no decisions or guarantees on the project design or outcome are made. Revision of the proposal based on input from the conceptual review is solely at the discretion of the applicant.
3. 
Community Conference. The community conference is an informal public meeting hosted by the applicant prior to submittal of a PUD application. The purpose of the meeting is to provide early and informal notification to the public, to generate discussion, and make the applicant aware of community concerns relative to the proposed project. It is intended to provide a means by which the applicant and the public can work together in a productive and creative manner. However, options and issues raised may not be all-inclusive and no decisions or guarantees on the project design or outcome are made. Revision of the proposal based on input from the community conference is solely at the discretion of the applicant.

Notice of the date, time and location and a project description shall be provided to the City and by mail to all owners of property within one thousand (1,000) feet of the PUD site two (2) weeks prior to the scheduled meeting date. All mailing requirements are the responsibility of the project applicant and shall be documented by affidavit to the City. City staff shall post a copy of the developer's notice at the site, Clayton City Hall and on the City's website.
b. 
Expectations. The applicant shall:
(1) 
Explain the project concept to the audience and solicit input as to the issues which concern them; and
(2) 
Invite the public to speak to issues related to the proposal, but their input shall not be considered public testimony regarding the application when and if submitted; and
(3) 
Prepare a written report documenting the community meeting, summarizing the issues raised, and describing how the proposed project, as submitted, addresses the issues raised in the project design and/or explains why it does not; and
(4) 
Submit said written report to the City for inclusion with the PUD application materials; and
(5) 
Provide a copy of the report to all the community meeting attendees prior to or concurrent with submittal of the PUD application materials to the City.
4. 
Staff Review. Upon the review of an application and plans, the Director of Planning and Development Services or his/her designee shall notify the applicant of any deficiencies and/or modifications necessary to perfect the application. Once the submittal is deemed complete, the application is forwarded to the Plan Commission and City Council for their consideration and approval, respectively.
5. 
Plan Commission Review And Recommendation. After due notice per Section 400.080, the Plan Commission may make recommendations to the City Council regarding the proposed PUD's compliance with requirements of this Article.
6. 
City Council Review And Decision. Approval of a PUD is determined solely in the legislative discretion of the City Council after hosting a Public Hearing.
B. 
Additional Review Procedures. In addition to the PUD process outlined in this Section, a PUD may also require concurrent review of the following applications:
1. 
Rezoning. A PUD is a distinct zoning district and requires a request for a change in the zoning district designation pursuant to Chapter 405, Article XI, Text Amendments and Rezoning.
2. 
Site Plan Review. A site plan application for the project shall be submitted and approved in accordance with the requirements and procedures set forth in Chapter 405, Article VIII.
3. 
Architectural Review. An architectural review application for the project shall be submitted and approved in accordance with the requirements and procedures set forth in Chapter 400, Article III.
4.

Section 405.1410 PUD Approval.

[Ord. No. 7020, 6-23-2026]
A. 
Criteria For PUD Approval. The approval criteria are designed to achieve the objectives as set forth in Section 405.1360 of this Article. The Plan Commission may recommend, and the City Council may adopt modifications to Code requirements as part of its consideration and approval of a PUD. In considering and acting upon development plans, landscape plans and other applicable plans, the Plan Commission and City Council shall take the following criteria into consideration:
1. 
The proposed development is in harmony with general purposes and intent of Chapter 405 of the Municipal Code and is compatible with and implements the planning goals and objectives of the City as set forth in the City's comprehensive plans.
2. 
Open Space And Landscaping. The quality and quantity of public and common open space and landscaping provided are consistent with higher standards of design and amenities expected of a PUD. Common spaces are adequate in size and design to accommodate public use.
3. 
External Circulation. Streets, sidewalks, pedestrian ways, bike paths, off-street parking and loading as appropriate to the planned land uses are provided and meet the City of Clayton standards. They will not unduly interfere with the safety and capacity of adjacent streets, or other means of access to the site.
4. 
Internal Circulation. The internal circulation system of the proposed development encourages safe movement for vehicles and pedestrians, and provides public access to green areas and open space preserved on site which are designated for public use.
5. 
Design. The PUD represents a more creative approach to the unified planning of development and incorporates a higher standard of integrated design and amenity than could be achieved under otherwise applicable zoning district and subdivision regulations.
6. 
Existing or proposed utility services are adequate for the proposed development.
7. 
Appropriate buffering is provided to protect adjacent land uses from light, noise and visual impacts.
8. 
Natural Features. The design of the PUD is as consistent as practical with the preservation of natural features of the site such as stands of mature trees, steep slopes, natural drainage ways, wetlands, or other areas of sensitive or valuable environmental character. The topography of the property is preserved to the greatest extent possible.
9. 
The proposed site layout and uses are compatible with the neighborhood surrounding the proposed development and the City as a whole.
10. 
The proposed development complies with all other applicable Codes and ordinances.
11. 
The proposed development preserves buildings which are architecturally or historically significant or contribute to the character of the City.
12. 
Public Welfare. The PUD will not be detrimental to the public health, safety or general welfare.
13. 
The proposed development provides the required number of public benefits to the extent outlined in Section 405.1380.
B. 
Approving Ordinance And PUD Document.
1. 
The City Council may impose conditions of approval and limitations as may be necessary or appropriate to prevent or minimize adverse effects upon other property and improvements near the planned unit development, upon the City as a whole or upon public facilities and services. These conditions, may include, but are not limited to, conditions concerning use, construction, character, location, landscaping, screening, parking, maintenance, operational elements that would impact adjoining land uses and other matters relating to the purposes and objectives of these regulations. Such conditions shall be expressly set forth in the PUD document which shall be an exhibit attached to the PUD ordinance authorizing the planned unit development. Violation of any such condition or limitation shall be a violation of these regulations and subject the offender to the penalties prescribed for the violation of this Chapter. Additionally, violation of any such condition or limitation shall be a violation of these regulations and shall constitute grounds for revocation of the approval authorizing the planned unit development.
2. 
The ordinance approving a PUD shall contain a legal description of the property subject to the planned unit development. The ordinance along with the PUD document and approved site plan shall be recorded by the applicant in the office of County Recorder of Deeds. The applicant must present proof of such recording before any permits may be issued.
3. 
Following planned unit development plan approval, the PUD document and approved site plan, rather than any other provision of Chapter 405, shall govern the use, parking, loading, height, building locations, open space and yard regulations applicable to the subject property and no use or development, other than temporary uses, shall be permitted within the area of the planned unit development pursuant to the zoning district regulations otherwise applicable to such area.
