Planned Developments And Planned Unit Development

Section 400.165 Definition, Purpose, Designation And Exceptions.

[Ord. No. 7042, 8-24-2023]

Definition. The term "Planned Development" refers to a specific parcel of land or several contiguous parcels of land under common ownership or control which, when designed in accordance with this Article and approved by the City Council, allow for the development of residential, commercial, office, high tech or industrial land by means of an alternate, more flexible method than would be permitted utilizing the City's conventional Zoning Code and Subdivision and Land Development Code regulations. A proposed Planned Development will only be reviewed if it is determined to meet the qualifying objectives to the satisfaction of the City Council of one (1) of the three (3) types of permitted Planned Developments outlined below. Under no circumstances will a Planned Development be permitted when the same development objectives can be accomplished utilizing the City's conventional Zoning Code and Subdivision and Land Development Code regulations.

Purpose. A Planned Development permitted in accordance with this Article shall be considered as an alternative method for the development of land under special circumstances described herein and only upon terms agreeable to the City Council. Because of this alternative method of development, special design standards are hereby established to govern and guide the creation of a Planned Development. To enable thorough analysis of a Planned Development, more information is demanded about the proposed development than would be required if the development were being proposed under the City's conventional Zoning Code and Subdivision and Land Development Code regulations. Therefore, all proposed Planned Developments must undergo a two (2) stage (area plan and final plan) review process through both the Planning and Zoning Commission and City Council per the requirements of this Article. It should be clearly understood that the review and approval of a Planned Development is a privilege to be earned based on the design of the project in full compliance with this Article. The decision to approve a proposed Planned Development shall be at the sole discretion of the City Council.

Planned Development Designation. With the exception of the zoning districts listed below, the City Council may attach the designation of Planned Development to land within any of the City's residential, commercial, high tech or industrial zoning districts in conjunction with the approval of an area plan per the requirements of this Article.

Exceptions To The Planned Development Designation. Under no circumstances shall the Planned Development designation be attached to the City's "R-5" Mobile/Manufactured Home Park District. "AG" Agricultural District, "P-R" Park-Recreation District, "TGD" Transitional Growth District or the Senior Community Overlay District. In addition, the Planned Development designation shall only be attached to the City's "R-3" Medium Density Residential District and "R-4" Apartment Building District if multi-family housing is proposed (either rental or owner-occupied). The Planned Development designation shall not be attached to the City's "MUTDD" Mixed-Use Traditional Development District. However, proposed developments utilizing the City's "MUTDD" Mixed-Use Traditional Development Zoning District must undergo the same two (2) stage (area plan and final plan) review process through both the Planning and Zoning Commission and City Council per the requirements of this Article.

Section 400.170 Types Of Planned Developments And The Qualifying Objectives.

[Ord. No. 7042, 8-24-2023]

Types Of Planned Developments And The Qualifying Objectives. The City Council shall only attach the Planned Development Designation to a site and subsequently approve a Planned Development if it is determined to meet the qualifying objectives to the satisfaction of the Council of one (1) of the three (3) types of permitted Planned Developments outlined below:

Environmental Protection Planned Developments. A proposed environmental protection planned development is for a residential, commercial, office, high tech or industrial site that must, to the satisfaction of the City Council, provide for the permanent protection and preservation of the natural features and environmentally sensitive areas of the site.

Qualifying Objectives. The qualifying objectives for permitting the review of a proposed environmental protection planned development is to encourage the permanent protection of the environmentally sensitive areas of a site while still allowing for the site's development by concentrating development away from these environmentally sensitive areas. In order to accomplish the separation of the environmentally sensitive areas from the areas of the site suitable for development, limited departure from strict conformance to the underlying zoning district regulations and/or Subdivision and Land Development Code regulations may be permitted by the City Council in accordance with the allowances of this Article.

Redevelopment Planned Developments. A proposed redevelopment planned development is for residential, commercial, office, high tech or industrial development at a specific site or location within the City that, as determined by the City Council, is in a state of decline and/or in need of redevelopment.

Qualifying Objectives. The qualifying objectives for permitting the review of a proposed redevelopment planned development is to provide an incentive for the development community to develop at these specific sites or locations. The incentive provided to the developer would be through the permitted flexibility of the design of the site by allowing for limited departure from strict conformance to the underlying zoning district regulations and/or Subdivision and Land Development Code regulations per the allowances of this Article. By allowing for the limited departure from strict conformance to these regulations, proposed developments that may not otherwise be financially feasible may become attractive to the development community. Although many proposed developments of this nature will instead be encouraged to utilize the City's "MUTDD" Mixed-Use Traditional Development Zoning District classification (which must follow the same two (2) stage area plan and final plan review and approval process outlined in this Article), there may be instances where proposed developments cannot meet the required size and/or required mix of residential and non-residential uses necessary to utilize the City "MUTDD" zoning classification.

Special Exception Planned Developments. A proposed special exception planned development is for a commercial, office, high tech or industrial site that, due to its irregular shape and size, would necessitate the need for variances from the City's Zoning Code and/or Subdivision and Land Development Code through the Board of Adjustment after the initial approval of the proposed development by the Planning and Zoning Commission.

Qualifying Objectives. The qualifying objectives for permitting the review of a proposed special exception planned development is to allow for both the Planning and Zoning Commission and City Council to comprehensively review the proposed development in its entirety (without the involvement of the Board of Adjustment) per the required two (2) stage area plan and final plan requirements of this Article. The variances needed for the proposed development would instead be reviewed as the proposed modifications to the underlying zoning district regulations and/or Subdivision and Land Development Code regulations per the allowances of this Article. This would no longer place the burden upon the Planning and Zoning Commission of having to decide whether a proposed development should be approved contingent upon receiving variances through the Board of Adjustment. This would also no longer place the burden upon the Board of Adjustment of having to decide whether or not to grant the requested variances on a proposed development that they have limited familiarity with that was approved by the Planning and Zoning Commission contingent upon receiving the variances.

Section 400.175 Design Standards For A Planned Development.

[Ord. No. 7042, 8-24-2023]

Size Requirements. There shall be no minimum or maximum size requirement for a site to be developed as a Planned Development.

Permitted Modifications To The Zoning District Regulations. Upon approval by the City Council, a Planned Development may depart from strict conformance to certain underlying zoning district regulations to which the Planned Development designation has been attached. The departure from strict conformance to these underlying zoning district regulations shall only be permitted if deemed necessary for the proper design of the Planned Development. Proposed modifications to the underlying zoning district regulations are limited to one (1) or more of the following:

Reduction of the minimum lot area requirements.

Reduction of the minimum lot width requirements.

Reduction of the minimum lot depth requirements.

Reduction of the front yard setback requirements.

Reduction of the side yard setback requirements.

Reduction of the rear yard setback requirements.

Reduction of the distance between grouped buildings requirements.

Increase in the maximum lot coverage requirements.

Increase in the maximum height requirements.

10.

Modification to the landscaping requirements.

11.

Modification to the off-street parking and loading requirements.

Permitted Modifications To The Subdivision And Land Development Code Regulations. Upon approval by the City Council, a Planned Development may depart from strict conformance to certain regulations of the Subdivision and Land Development Code. The departure from strict conformance to these Subdivision and Land Development Code regulations shall only be permitted if deemed necessary for the proper design of the Planned Development. Proposed modifications to the Subdivision and Land Development Code are limited to one (1) or more of the following:

Reduction of the minimum right-of-way requirements for minor residential and cul-de-sac streets.

Reduction of the minimum centerline radii for minor residential and cul-de-sac streets.

Reduction of the minimum corner radii at the back of curb for minor residential and cul-de-sac streets.

Reduction of the minimum block length.

Increase in the maximum block length.

Increase in the maximum length of cul-de-sacs.

Modification to the requirements for private alleys.

Modification to the requirements for sidewalks.

Modification to the requirements for street tree placement.

Regulations Which May Not Be Modified. A Planned Development must meet the use and density limitations of the underlying zoning district in which the development is to be located. All requirements of the underlying zoning district and the Subdivision and Land Development Code remain applicable except as specifically modified pursuant to the allowance of this Article as approved by the City Council. Under no circumstances shall the applicable flood hazard prevention requirements, stormwater detention requirements, grading requirements, soil erosion and sediment control requirements, central utility requirements, tree preservation requirements, screening of outdoor equipment requirements, or performance standards (e.g., air and water pollution, noise, odor, fire hazard, etc.) be modified in conjunction with the approval of a Planned Development. In addition, all other City, County, State, and Federal regulations and development requirements shall apply to the Planned Development.

Residential Density. Under no circumstances shall the residential density of a Planned Development exceed that which would normally be permitted in the underlying residential zoning district to which the Planned Development designation has been attached.

Calculation Of Density. The computation of residential density shall be based on the dwelling units per net acreage of the residentially zoned portion of the site. Net acreage is determined by subtracting the area devoted to public street rights-of-way, private alleys and dry detention basins from the gross acreage of the residentially zoned portion of the site. To compute residential density, the net acreage of the residentially zoned portion of the site shall be divided by the smallest minimum lot size allowed in the underlying residential zoning district to which the Planned Development designation has been attached. In situations where a Planned Development designation is attached to two (2) or more underlying residential zoning districts, the residential density shall be calculated separately for each of the underlying residential zoning district to which the Planned Development designation has been attached.

Permanent Protection Of Environmentally Sensitive Areas. All environmental protection planned developments shall, to the satisfaction of the City Council, be designed in accordance with the following requirements:

No modification, alteration or construction of any type may occur in flood hazard areas. This includes all floodways, all floodway fringe areas, areas of 500-year flood, areas of 100-year flood with average depths of less than one (1) foot or with drainage areas less than one (1) square mile, and areas protected by levees from 100-year flood.

No modification, alteration or construction of any type may occur in areas containing wetlands as determined by the U.S. Army Corp of Engineers.

No modification, alteration or construction of any type may occur in ditches, creeks, streams, or other watercourses and natural drainage ways vital to the natural performance of the watershed as determined by the City's Stormwater Engineer.

No modification, alteration or construction of any type may occur in areas where slopes are in excess of forty percent (40%). To the maximum extent feasible, cutting, filling and benching or terracing of areas with slopes ranging from fifteen percent (15%) to forty percent (40%) for the purpose of creating additional building area or larger building sites shall be prohibited.

No modification, alteration or construction of any type may occur in areas containing soils classified as A-6 to A-8 on the American Association of State Highway and Transportation Officials (A.A.S.H.T.O.) Soil Classification System. These soils are classified as either easily erodible, clayey or highly organic as defined by the Soil Survey of St. Charles County, Missouri, published by the United States Department of Agriculture (U.S.D.A.) Soil Conservation Service. The water table may not be higher than one (1) foot below the lowest floor in any proposed structure.

No modification, alteration or construction of any type may occur in areas determined to be vital aquifer recharge or discharge areas as determined by the Missouri Department of Natural Resources, the U.S. Army Corp of Engineers or the City's Stormwater Engineer.

No modification, alteration or construction of any type may occur in areas determined to be vital for the protection of wildlife as determined by the Missouri Department of Conservation.

No modification, alteration or construction of any type may occur in areas determined to be of archaeological or historical significance as determined by the Missouri Department of Natural Resources State Historic Preservation Office.

Existing trees preserved within the areas within the environmental protection planned development subject to the above-listed requirements may be counted towards meeting the tree preservation requirements of Chapter 402, Trees and Landscaping, of this Code.

10.

All areas within the environmental protection planned development subject to the above-listed requirements shall be identified on a separate environmentally sensitive area protection plan included as part of both the area plan and final plan applications. The environmentally sensitive area protection plan may be combined with the tree preservation plan required per Chapter 402 of this Code.

11.

All areas within the environmental protection planned development subject to the above-listed requirements shall be protected through the establishment of a permanent conservation easement held by the landowner(s), a homeowners' association or a land trust.

Common Ground Requirements. At least twenty percent (20%) of the gross land area of an environmental protection planned development or a residential redevelopment planned development, or an area of a size equivalent to one (1) acre for each one hundred (100) persons of expected population of the development, whichever is greater, shall be set aside as common ground. The expected population shall be determined by multiplying the total number of dwelling units by three (3) persons (the City's average household size per the 2020 Census). Common ground shall be designed in accordance with the following requirements:

Private alleys and dry detention basins may not be counted towards meeting the common ground requirement.

The natural areas protected through the establishment of the required permanent conservation easement in an environmental protection planned development may be included in meeting all or part of the common ground requirement. The extent that these natural areas may be counted towards meeting the common ground requirement will be dependent upon the suitability of the natural areas for use by residents as determined by the City Council.

To the satisfaction of the City Council, throughout environmental protection planned developments and residential redevelopment planned developments, common ground shall be equitably distributed in relation to the dwelling units that such common ground is intended to serve and shall be connected via a series of sidewalks, paths or multi-purpose trails.

Lakes that serve the dual purpose of stormwater retention may be counted towards meeting one-fourth (1/4) of the common ground requirement.

Areas within common ground that contain recreational amenities shall be counted towards meeting the common ground requirement.

The use, operation and maintenance of common ground within an environmental protection planned development or a residential redevelopment planned development shall be guaranteed by the establishment of trust indentures providing for the establishment of a homeowners' association. Said trust indentures shall be approved by the City staff prior to recording the trust indentures simultaneously with the recording of the record plat.

Perimeter Buffering Requirements. Regardless of political boundaries, when a residential Planned Development is proposed adjacent to an existing residential development or residential zoning district, there shall be a minimum twenty (20) foot wide permanent buffer area. Regardless of political boundaries, when a residential Planned Development is proposed adjacent to an existing commercial, office, high tech or industrial land use or non-residential zoning district, there shall be a minimum thirty (30) foot wide permanent buffer area. Regardless of political boundaries, when a non-residential Planned Development is proposed adjacent to an existing residential development or residential zoning district, there shall be a minimum thirty (30) foot wide permanent buffer area. These buffer areas shall be: 1) uniform in setback at all points on the perimeter of the Planned Development; 2) kept in a natural state (if sufficient tree mass exists) or landscaped and/or otherwise provided with screening (i.e., sightproof fencing and/or landscaped earthen berms) to the satisfaction of the City Council; and 3) be kept free of buildings, structures and impervious surfaces. These buffer areas may be designated as common ground or placed within permanent easements on the individual lots. If these buffer areas are placed within permanent easements on the individual lots, the required building setbacks shall be measured from the inside line of the permanent easements.

Perimeter Minimum Lot Size Requirements. The perimeter lots within a proposed residential Planned Development adjacent to any existing, proposed, approved or under construction residential subdivision (regardless of political boundaries) must meet or exceed the size and dimensional configuration of the adjacent residential lots in the neighboring subdivision. The only exception to this requirement is when the perimeter lots of a proposed residential Planned Development are adjacent to existing, proposed, approved or under construction residential lots in a neighboring subdivision (regardless of political boundaries) that are two (2) acres or greater in size. When the perimeter lots of a proposed residential Planned Development are adjacent to existing, proposed, approved or under construction residential lots in a neighboring subdivision (regardless of political boundaries) that are two (2) acres or greater in size, the perimeter lots of a proposed residential Planned Development adjacent to these lots shall be a minimum of two (2) acres in size.

Effect Of An Approved Area Plan. The approval of an area plan by the City Council shall authorize the applicant to request approval of the final plan(s) for the proposed Planned Development per the requirements of this Article. The approval of an area plan shall run with the land and shall remain valid if there is a subsequent change in the ownership of any or all of the area encompassing the Planned Development. If the Planned Development involves the subdivision of land, the approval of the area plan also serves as the simultaneous approval of a preliminary plat. In addition, the approval of the area plan allows the developer to seek approval of grading plans for the site per the requirements of Section 405.070 of the Subdivision and Land Development Code.

Official Planned Development Designation. Within five (5) working days of approval of the area plan and Planned Development designation by the City Council, the Mayor shall accurately note, and the City Clerk shall attest, the Planned Development designation for the site in question on the City's Official Zoning Map. The symbol "PD" will be placed over the underlying zoning district classification.

Expiration Of An Approved Area Plan. The approved area plan for a Planned Development that is to be constructed in a single phase shall expire and be deemed null and void and without force or effect one (1) year after the date of approval unless a final plan has been approved by the City Council. For a Planned Development that is to be constructed in two (2) or more phases, the approved area plan shall expire and be deemed null and void and without force or effect one (1) year after the date of approval unless a final plan has been approved by the City Council for the initial phase. The final plans for all subsequent phases must be approved by the City Council within two (2) years of the date of the original area plan approval.

Extension Of Time Of An Approved Area Plan. Upon written request by the applicant, if good cause can be shown, the City Council, in its discretion, may grant an extension of time of up to one (1) year from the date of the initial expiration of the area plan for the date of approval for the final plan by the City Council [or initial final plan for a Planned Development that is to be constructed in two (2) or more phases]. In granting said extension, the City Council may attach any additional conditions deemed necessary above and beyond those required of the original approved area plan.

Modifications Of An Approved Area Plan. The final plan(s) submitted for review by the Planning and Zoning Commission and City Council shall conform to the area plan approved by the City Council. However, if deemed appropriate by the Planning and Zoning Commission during their initial review of the final plan(s), minor variations from the approved area plan may be permitted. A detailed description of all changes must be provided. Major modifications shall require a revised area plan application. Minor modifications are limited to the following:

A reduction in the land area to be included in the Planned Development if the proposed lot layout and transportation system remain relatively unaffected.

An increase in the land area to be included in the Planned Development not to exceed five percent (5%) if the proposed lot layout and transportation system remain relatively unaffected.

Section 400.236 "PUD" Planned Unit Development.

[Ord. No. 7042, 8-24-2023]

Purpose. The provisions of this Section are designed to deal with large-scale development and facilitate better site planning and community planning through modification of certain district regulations as they apply to such development.

It is hereby recognized that, for large-scale development, the regulations of districts in the Zoning Code, either individually or collectively, might impose unnecessary or undesirable rigidities on the site plan and thereby prevent achievement of the best possible plan within the Code. Therefore, this Article has the following intents:

To permit flexibility in site design.

To achieve more efficient use of land, within the framework and intent of the Zoning Ordinance, which can result from large scale or multiple use developments.

To encourage and permit provision of open space.

To protect and preserve scenic assets and natural features and to incorporate these into the development.

To foster a more stable community by providing a variety and balance of housing types and living environments.

To encourage and permit variety in the location of buildings, roads, parking lots, and other facilities and activities.

To increase the safety of pedestrian and vehicular traffic by reducing the number of traffic conflict points within a development.

To reduce land cost per dwelling unit in residential developments.

This Article is intended to achieve these objectives while promoting and protecting the public health safety, and welfare of the City, and while safeguarding the present or future use and development of areas surrounding a proposed "PUD."

The "PUD" designation is to be attached to the "R-1," "R-2" and "R-3" Zoning Districts set forth in this Chapter and is not a separate use district. The "PUD" designation may be attached to a parcel of land at the time its zoning classification is amended.

Permitted Modifications To The Zoning District Regulations. Upon approval by the City Council, a Planned Unit Development may depart from strict conformance to certain underlying zoning district regulations to which the Planned Unit Development designation has been attached. The departure from strict conformance to these underlying zoning district regulations shall only be permitted if deemed necessary for the proper design of the Planned Unit Development. Proposed modifications to the underlying zoning district regulations are limited to one (1) or more of the following:

Reduction of the minimum lot area requirements.

Reduction of the minimum lot width requirements.

Reduction of the minimum lot depth requirements.

Reduction of the front yard setback requirements.

Reduction of the rear yard setback requirements.

Reduction of the distance between grouped buildings requirements.

Increase in the maximum lot coverage requirements.

Increase in the maximum height requirements.

Modification to the landscaping requirements.

10.

Modification to the off-street parking and loading requirements.

Permitted Modifications To The Subdivision And Land Development Code Regulations. Upon approval by the City Council, a Planned Unit Development may depart from strict conformance to certain regulations of the Subdivision and Land Development Code. The departure from strict conformance to these Subdivision and Land Development Code regulations shall only be permitted if deemed necessary for the proper design of the Planned Unit Development. Proposed modifications to the Subdivision and Land Development Code are limited to one (1) or more of the following:

Reduction of the minimum right-of-way requirements for minor residential and cul-de-sac streets.

Reduction of the minimum centerline radii for minor residential and cul-de-sac streets.

Reduction of the minimum corner radii at the back of curb for minor residential and cul-de-sac streets.

Reduction of the minimum block length.

Increase in the maximum block length.

Increase in the maximum length of cul-de-sacs.

Modification to the requirements for private alleys.

Modification to the requirements for sidewalks.

Modification to the requirements for street tree placement.

Regulations Which May Not Be Modified. A Planned Unit Development must meet the use and density limitations of the underlying zoning district in which the development is to be located. All requirements of the underlying zoning district and the Subdivision and Land Development Code remain applicable except as specifically modified pursuant to the allowance of this Article as approved by the City Council. Under no circumstances shall the applicable flood hazard prevention requirements, stormwater detention requirements, grading requirements, soil erosion and sediment control requirements, central utility requirements, tree preservation requirements, screening of outdoor equipment requirements, or performance standards (e.g., air and water pollution, noise, odor, fire hazard, etc.) be modified in conjunction with the approval of a Planned Unit Development. In addition, all other City, County, State, and Federal regulations and development requirements shall apply to the Planned Unit Development.

Section 400.236.5 Procedure For Area Plan Review.

[Ord. No. 7042, 8-24-2023]

Upon receipt of the area plan from the Planning and Development Department, the Planning and Zoning Commission shall undertake a study of the area plan. The Planning and Zoning Commission shall advise the applicant, in writing, of any recommended changes in the area plan as are needed to conform to the standards of this Chapter and other pertinent ordinances.

The Planning and Zoning Commission shall, at the next meeting after which it receives the area plan from the Planning and Development Department, establish a public hearing on the area plan, said hearing to be held within thirty-one (31) days of the filing date or at the regular Planning and Zoning Commission meeting closest to that date. At least fifteen (15) days' notice of the hearing shall be published in a newspaper of general circulation along with hearing notice for a zoning amendment for the tract in question, if such amendment is applied for. The public hearing may be held jointly with a public hearing on any zoning change for the tract in question.

The Planning and Zoning Commission shall prepare a report on the area plan and shall submit this report to the City Council. This report shall contain the Planning and Zoning Commission's analysis of the area plan and its recommendations thereon to the City Council. If a zoning amendment application is made for the subject lot, the Commission shall report to the City Council its review and recommendations concerning said amendment simultaneously with its reports on an area plan.

The City Council shall review the area plan, and the report of the Planning and Zoning Commission thereon, and shall approve or deny the area plan. If a zoning amendment application has been made for the subject tract to permit the development proposed in the area plan, the City Council shall take action on such amendment before taking action on the area plan.

If the area plan is approved by the City Council, the applicant shall review the area plan in its approved form. The applicant and the owner(s) of record shall then sign a statement that the approved area plan shall be binding upon the applicant and the owner(s) of record and upon their heirs, successors, and assigns. The area plan shall not be officially approved nor may the applicant submit a final plan for the lot or any part thereof, until said statement has been signed as required herein. The foregoing approval and signing shall constitute official approval of the "PUD" designation for the subject tract. Rezoning may be made contingent upon the "PUD" statement being properly signed.

Within five (5) working days of the official approval of an area plan, the Mayor shall accurately note, and the City Clerk attest, the "PUD" designation for the lot in question on the Official Zoning Map.

Section 400.236.6 Standards For Area Plan Approval.

[Ord. No. 7042, 8-24-2023]

The Planning and Zoning Commission shall determine and shall provide evidence of same in its report to the City Council and the City Council shall determine, based upon its review of the Planning and Zoning Commission's report and its own findings, that the proposed area plan meets the intent of this Chapter and meets the following standards.

The use of land shall be in conformance with the permitted uses of the district, in which the proposed development is to be located, and conforms to the adopted Comprehensive Plan or any part thereof, or represents land use policy which, in the Planning and Zoning Commission's opinion, is a logical and acceptable change in the adopted Comprehensive Plan.

The average density of development within the "PUD" shall remain the same as would be permitted if the area were to be developed conventionally. Average density is to be calculated as total land area excluding public right-of-way, land to be used as detention basins and common ground. Common ground may be used in the calculations if it is developed with acceptable amenities or is otherwise developable open space. An undeveloped watershed corridor will not be counted as common ground in the average density calculation. However, the development (buildings) so permitted may be clustered and located irrespective of yard setback requirements or lot lines in order to create a smaller network of streets and utility lines and to create additional open space for the enjoyment of the residents. Improvements required by the City Code will not be considered an acceptable amenity.

The proposed development shall be adequately served by public facilities and services, such as: highways, streets, police and fire protection, drainage courses, water and sanitary sewer facilities refuse disposal; or that the persons or agencies responsible for the proposed development shall be able to provide, in a manner acceptable to the City Council, any such facilities and services.

Each phase of the proposed development shall not be dependent upon completion of subsequent phases of the same development for the facilities and services identified in Subsection (A)(3) above.

The common open space, any other common properties, individual properties, and all other elements of the "PUD" are so planned that they will achieve a unified environmental scheme, with open spaces and all other elements in appropriate locations, suitably related to each other, the site, and the surrounding land. All common spaces shall be permanently secured as such to the satisfaction of the City Council.

The location of the proposed uses, layout of the site and its relation to streets giving access to it, shall be such that traffic to, from, and within the tract, and concentration of persons in connection therewith, will not be hazardous or inconvenient to the project or the neighborhood. In applying this standard, the Planning and Zoning Commission and City Council shall consider among other things, convenient routes for pedestrian traffic, particularly of children; relationship of the proposed project to main thoroughfares and street intersections; and the general character and intensity of the existing and potential development of the neighborhood.

Where applicable, the Planning and Zoning Commission and City Council shall determine that noise, odor, light, or other external effects from any source whatsoever, which are connected with the proposed use, will not adversely affect adjacent and neighboring areas and uses.

Yard requirements along the perimeter of the "PUD" shall be at least equal to those required in district(s) in which the "PUD" is located.

Perimeter buffering requirements. Regardless of political boundaries, when a Planned Unit Development is proposed adjacent to an existing residential development or residential zoning district, there shall be a minimum twenty (20) foot wide permanent buffer area. These buffer areas shall be: 1) uniform in setback at all points on the perimeter of the Planned Unit Development; 2) kept in a natural state (if sufficient tree mass exists) or landscaped and/or otherwise provided with screening (i.e., sight proof fencing and/or landscaped earthen berms) to the satisfaction of the City Council; and 3) be kept free of buildings, structures and impervious surfaces. These buffer areas may be designated as common ground or placed within permanent easements on the individual lots. If these buffer areas are placed within permanent easements on the individual lots, the required building setbacks shall be measured from the inside line of the permanent easements.

Section 400.236.7 Effect Of Area Plan Approval.

[Ord. No. 7042, 8-24-2023]

Approval of the area plan by the City Council shall have the following effects:

Approval shall assure the applicant that the area plan is acceptable to the City Council for the three (3) year period, provided construction is diligently pursued, and authorizes the applicant to file a final site plan for the entire tract or portion thereof if the "PUD" is developed in phases.

Official approval of the area plan shall confer "PUD" status to the subject tract and permit modifications of lot area, lot width, yard requirements, and spacing among buildings and structures within the lot, except on the perimeter thereof, all as set forth in the approved area plan.

No deviations from the area plan approved by the City Council shall be permitted except as provided in this Article.

Approval of the area plan of a "PUD" shall expire and be of no effect one (1) year after the date of approval unless a final plan has been approved by the Planning and Zoning Commission.

Section 400.236.8 Information Required Final Plan.

[Ord. No. 7042, 8-24-2023]

Every final plan submitted to the Planning and Zoning Commission shall be in accordance with the requirements of this Section and have addressed all conditions of approval for the area plan review. The final plan submittal shall address and/or contain the following:
