[CC 1976 App. A §4.10; Ord. No. 2449 §1, 11-14-1988; Ord. No. 2542 §2, 12-11-1989; Ord. No. 99-53 §1, 7-13-1999: Ord. No. 2003-12 §1, 2-24-2003; Ord. No. 2003-13 §1, 2-24-2003; Ord. No. 2025-54, 12-8-2025]
A. Intent And Purpose. The purpose of the Planned Development District is to provide a means of achieving greater flexibility in development of land in a manner not possible in conventional zones; to encourage a more imaginative and innovative design of projects; to promote a more desirable community environment; and to retain maximum control over both the structure and future operation of the development.
The City Council, upon recommendation by the Planning and Zoning Commission, may, by ordinance adopted in the same manner as Zoning Districts are created, authorize a Planned Development District when the proposed development or use of a specific tract of land or area warrants greater flexibility, control, and density than is afforded under the general regulations of standard zoning districts. However, it should be noted that these planned development regulations are not intended to allow excessive densities, or the development of incompatible land uses, either within the development, or as the development relates to the general neighborhood. The standards contained in the following provisions must be strictly adhered to by the applicant.
The City may, upon proper application, approve a planned development to facilitate the use of flexible techniques of land development and site design, by providing relief from zone requirements designed for conventional developments in order to obtain one (1) or more of the following objectives:
1. Environmental design in the development of land that is of a higher quality than is possible under the regulations otherwise applicable to the property.
2. Diversification in the uses permitted and variation in the relationship of uses, structures, open space and height of structures in developments intended as cohesive, unified projects.
3. Functional and beneficial uses of open space areas.
4. Preservation of natural features of a development site.
5. Creation of a safe and desirable living environment for residential areas characterized by a unified building and site development program.
6. Rational and economic development in relation to public services.
7. Efficient and effective traffic circulation, both within and adjacent to the development site.
B. Relationship Of Planned Development Districts To Zoning Map.
1. A mapped district. The "PD" designation is not intended to be attached to existing use districts as an overlay. The "PD" designation as detailed in this Section is a separate use District and may be attached to a parcel of land as an original Zoning District, or it may be attached to a parcel of land through the process of Zoning Map amendment.
2. Plan approval required. Although the "PD" designation may be applied to parcels of land as a mapped Zoning District, it is the intent of this Chapter that no development or redevelopment of the property encompassed by the "PD" designation take place until an acceptable development plan has been reviewed and approved in conformance with the requirements of this Section. Any pre-existing uses within the area encompassed by the "PD" designation shall have the status of non-conforming uses, as outlined in Article
VIII, until such time as they are included in an approved development plan.
3. Types of planned developments. All areas of the City subject to the "PD" designation shall be assigned one (1) of the following subclassifications which shall be considered a separate use district and subject to the specific restrictions and limitations outlined in this Section:
a. Planned development-residential ("PD-R"). Planned developments involving residential uses only.
b. Planned development-commercial ("PD-C"). Planned developments involving commercial uses only.
c. Planned development-manufacturing ("PD-M"). Planned developments involving manufacturing uses only.
d. Mixed use developments ("MXD"). Planned developments involving a mixture of residential and non-residential uses.
| These subclassifications may be designated by the City at the time of the original zoning of the parcel in question, or the City may make the designation at the time of development plan application. In the instance of a request for Zoning Map amendment, the applicant may request a specific subclassification; however, it shall be at the discretion of the City, in light of the recommendations of the City's comprehensive plan, as well as the surrounding neighborhood to grant the requested subclassification or require a more restrictive one. |
4. Exception. Notwithstanding anything herein to the contrary, any owner of the lot on which there is proposed to be constructed a structure having an estimated cost of less than one hundred thousand dollars ($100,000.00), exclusive of demolition and site preparation costs, shall not be required to comply with the requirements of this Section
400.250. The owner of the lot on which such construction is proposed shall comply with the district requirements as follows:
| District Designation | Requirements |
|---|
| "PD-R" | "R-1" |
| "PD-C" | "C-2" |
| "PD-M" | "M-1" |
| "PD-MxD" | "R-4" |
| Any improvements so constructed shall be considered a conformed building. |
C. Procedures For Planned Development Approval.
1. Preapplication procedure. Not more than six (6) months prior to filing any application for planned development approval the prospective applicant shall request a preapplication conference with the City's staff. Such request shall include a brief and general narrative description of the nature, location and extent of the proposed planned development, and a list of any professional consultants advising the prospective applicant with respect to the proposed planned development. Upon receipt of such request the City planning staff shall schedule within ten (10) days such a conference.
2. Preliminary development plan. A preliminary development plan shall be submitted to the Planning and Zoning Commission with the application for a planned development. The preliminary plan shall contain the following information:
a. Site and landscape plan. One (1) or a series of maps shall be submitted indicating:
(1) The location, size and height of all existing and proposed structures on the site.
(2) The location and general design (width and materials) of all driveways, curb cuts and sidewalks including connections to building entrances; as well as the location and nature of construction of all curb guttering.
(3) The location, area and number of proposed parking spaces.
(4) Existing and proposed grades at an interval of five (5) feet or less, extended beyond the project site to include adjacent properties and structures.
(5) The location and general type of all existing trees over six (6) inch caliper and, in addition, an indication of those to be retained.
(6) The proposed general use and development of internal spaces, including all recreational and open space areas, plazas and major landscaped areas by function, and the general location and description of all proposed outdoor furniture (seating, lighting, telephones, etc.).
(7) The location and approximate size of all proposed plant material by type, such as hardwood/deciduous trees, evergreen trees, flowering trees and shrub masses, and types of ground cover (grass, ivies, etc.). Planting in parking areas should be included.
(8) The location of all retaining walls, fences (including privacy fences, etc.) and earth berms.
(9) The definition and location of all refuse collection facilities, including screening to be provided.
(10) Provisions for both on- and off-site stormwater drainage and detention related to the proposed development.
(11) The limits of the one hundred (100) year floodplain boundary and floodway designations as they impact the site.
| The scale of the drawing or drawings indicating the above shall be reasonably related to the site size and the complexity of the proposed development, and the scale shall in no event be smaller than one (1) inch equals fifty (50) feet. All drawings shall likewise indicate a project name, the names of adjoining streets, the applicant's name, a scale, a north arrow, and the date drawn. |
| The applicant may be required to provide, at applicant's expense, additional clarification and/or further detail of the preliminary plan, as deemed necessary by the Planning and Zoning Commission. |
b. Site and building sections. Schematic or illustrative sections shall be drawn to a scale of one (1) inch equals eight (8) feet or larger, indicating both edge conditions and internal grade changes in relation to principal variations of internal building levels and site line relations to adjacent structures.
c. Architectural elevations. Architectural elevations of proposed buildings shall be provided at a reasonable scale.
d. Project data.

400.250(C)(2), shall be considered at the first (1st) regularly scheduled Planning and Zoning Commission meeting or as soon thereafter as is practical, but not sooner than twenty-one (21) days from the filing of the completed application. Notices of the Planning and Zoning Commission meeting shall be sent to owners of record of all properties within three hundred (300) feet of the parcel included in the application. The application shall be accompanied by a fee of one thousand dollars zero cents ($1,000.00).
b. Staff review. The Director of Public Works shall coordinate a review of the application by appropriate affected City departments. A written report documenting the review and staff recommendations shall be prepared by the Director of Public Works or his/her designee and submitted to the Planning and Zoning Commission at the meeting at which it first considers the application.
c. After consideration of the application and staff report, the Planning and Zoning Commission shall make a report to the City Council regarding the impacts of such proposed building or use upon the character of the neighborhood, traffic conditions, public utility facilities, and other matters pertaining to the general public health, safety and welfare of the City of Overland. The findings and recommendation of the Commission shall be transmitted to the City Council. If the Commission's recommendation is for approval, its report shall contain the conditions or restrictions recommended by the Commission with respect to the preliminary development plan.
d. The City Council shall hold a public hearing thereon upon at least fifteen (15) days' public notice. If the preliminary development plan is approved by the City Council, it shall adopt an ordinance approving said preliminary development plan with conditions as specified therein. In those instances where the application involves a rezoning from a standard Zoning District to a planned district designation, approval of the preliminary development plan shall constitute approval of the rezoning request. The ordinance approving the preliminary development plan shall include the change in zoning designation as well as the specified conditions attached to approval of the plan as previously discussed. A three-fourths (¾) vote of the City Council shall be required to overrule the Planning and Zoning Commission's recommendations.
e. The approval of a preliminary plan shall be valid for a period of nine (9) months from the date of its approval by the City Council. The Commission may grant extensions not exceeding six (6) months each upon written request of the original applicant if the application submitted is substantially the same as the initially approved application. At such time as the period of validity of an approved preliminary development plan lapses, the site shall revert back to its previous land use status prior to approval of the preliminary development plan.
Should a request for extension of an approved preliminary development plan contain substantial changes, as determined by the Commission, the Commission shall require the applicant to refile his/her application subject to the requirements of this Section, as if it were an entirely new application.
4. Final plan. Within nine (9) months following passage of the ordinance approving the preliminary development plan, but at least twenty-one (21) days before a regularly scheduled meeting of the Planning and Zoning Commission, the petitioner shall submit a final development plan to the Director of Public Works (or the Planning and Zoning Commission upon appeal) for review and consideration to determine if said final development plan is in conformance with the approved preliminary development plan and with the imposed conditions of approval. The final development plan shall reflect the entire planned development if it is to be completed in one (1) phase, or a phase of the planned development if it consists of more than one (1) phase. The final development plan, in addition to the matters shown on the preliminary development plan shall include the following:
a. The existing and proposed contours at two (2) foot intervals.
b. The landscape plan with the specific location of all plant material, specifying size, species and location (both as to the buffer area around the perimeter as well as that in the parking lot).
c. Nature of use, as single-family, condominium, or multi-family, and/or commercial or manufacturing uses.

400.250(C)(4), shall be submitted to the Director of Public Works for review and approval. The application shall be accompanied by a fee of one hundred fifty dollars ($150.00). If the Director of Public Works finds that the final development plan conforms to the approved preliminary development plan, he/she shall approve it, send written notice of the approval to the Planning and Zoning Commission, and transmit the plan to the Planning and Zoning Commission Chairman for his/her signature. If the Director of Public Works finds that the final development plan does not conform to the approved preliminary plan, he/she shall deny the final development plan and return it to the applicant with a written response concerning the reasons for denial. The applicant shall have thirty (30) days in which to file a written appeal of the denial to the Planning and Zoning Commission.
b. Upon appeal, and after consideration of the application and staff report, the Planning and Zoning Commission shall approve, approve with conditions, or deny the final development plan. The final development plan shall conform to the preliminary development plan. If the final development plan does not conform to the preliminary development plan, or if the conditions of the preliminary development plan approval are not adequately met, the final development plan shall not be approved.
c. Upon approval of the final development plan by either the Director of Public Works or the Planning and Zoning Commission upon appeal, the final development plan shall be transmitted to the City Council for their information.
d. Within sixty (60) days following approval of the final development plan by the Planning and Zoning Commission, it shall be recorded at the applicant's expense with the St. Louis County Recorder of Deeds, and a reproducible mylar of such recorded plan furnished to the Director of Public Works. Any bonds required to insure completion of required improvements or open space shall be completed and in place prior to recording of the final development plan.
D. Permitted Land Uses.
1. The following land uses are permitted in this District and its subclassifications:
a. Subject only to approval of a site plan:
(1) Police, fire and governmentally operated emergency service facilities; and
(2) Accessory uses incidental to the above uses.

| Planned development — manufacturing | |
| Planned development — mixed | |
2. Modifications. The approval of the preliminary development plan may provide for such exceptions from the above-referenced regulations as may be necessary or desirable to achieve the objectives of the proposed planned development, provided such exceptions are consistent with the standards and criteria contained in this Section and have been specifically requested in the application for a planned development; and further, that no modification of the above-referenced regulations would be allowed when such proposed modification would result in:
a. Inadequate or unsafe access to the planned development.
b. Traffic volumes exceeding the anticipated capacity of the proposed major street network in the vicinity.
c. An undue burden on public parks, recreation areas, schools, fire and police protection and other public facilities which serve or are proposed to serve the planned development.
d. A development which will be incompatible with the purposes of this Chapter.
e. Detrimental impact on the surrounding area including, but not limited to, visual pollution.
| The burden of proof that the criteria above are not being violated shall rest with the developer and not the staff or the Planning and Zoning Commission. |
F. Period Of Validity. The period of validity of approval of a final development plan is as follows:
1. No approval of a final development plan shall be valid for a period longer than twelve (12) months from the date of approval by the Director of Public Works, or the Planning and Zoning Commission if on appeal, unless within such period a building permit is obtained and construction is commenced. One (1) month prior to the expiration of the approval, the Director of Public Works shall notify the applicant in writing of the impending expiration date.
