The sketch plan shall show each mobile home space, the water, electrical, and sewer lines serving each mobile home space, the location of garbage receptacles, water hydrants, service buildings, driveways, walkways, recreation areas, playgrounds, required yards, existing and proposed grading, parking facilities, storm shelter, lighting, landscaping, and the location of existing trees, buildings, or other significant features. Prior to development, a Site Plan must be submitted. The Site Plan will be considered by the Planning and Zoning Commission and the Council, who may approve or disapprove the plan or require such changes thereto as deemed necessary. The Site Plan shall be accompanied by a covenant to run with the land, in favor of the City and all persons having a possessory interest in any portion of the mobile home park, that the owner or owners of the park, or their successors in interest, will maintain all interior streets, parking areas, sidewalks, and plantings in compliance with City ordinances and the Site Plan as approved by the Council, which covenant shall be recorded in the office of the County Recorder.

   5.   Parking. A minimum of two off-street car spaces directly accessible to the private street for each mobile home lot shall be provided. Garage stalls shall not count toward the minimum off-street parking requirements. These required parking spaces, or parking areas, shall be so located as to provide convenient access to the mobile homes, but shall not exceed a distance of 200 feet from the mobile home that it is intended to serve. All parking areas shall be constructed with a concrete or asphaltic concrete surface. Parking stalls shall be a minimum of nine and one-half feet in width by 20 feet in length.
   6.   Streets. The entrance road connecting the park streets with a public street shall have a minimum road pavement width of 31 feet, measured back to back of curbs. All interior streets shall be not less than 26 feet in width, measured back to back of curbs. All streets shall be constructed in accordance with appropriate ordinances and specifications of the City.
   7.   Anchoring and Skirting.
      A.   Tie-downs or anchors shall be provided on every mobile home stand. Each tie-down or anchor must be able to sustain a minimum tensile strength of 2,800 pounds.
      B.   Skirting of a permanent type material and construction shall be installed within 90 days to enclose the open space between the bottom of a mobile home floor and the grade level of the mobile home stand. This skirting shall be maintained in an attractive manner consistent with the exterior of the mobile home and to preserve the appearance of the mobile home park.
   8.   Utilities. Sewer and water facilities shall be provided for each mobile home lot in accordance with the requirements of the Iowa State Department of Health. All units shall be individually metered in accordance with City regulations. All mobile home developments must be connected to the municipal sanitary sewer system and the municipal water system. All electrical and telephone lines shall be placed underground. All gas lines shall be black steel, 120#. Each unit shall have an accessible water shut-off valve as approved by the Water Department.
   9.   Storm Shelters. Mobile homes are extremely vulnerable to tornadoes and other high wind conditions. The greatest number of casualties in tornadoes generally come from mobile home developments. This is primarily due to the fact that the mobile home is usually not anchored to as firm of a foundation as a regularly constructed building and cannot take the impact of the extremely high winds and the accompanying flying debris. Tie-downs do not greatly increase the stability in extremely high wind or tornado type conditions, though may be fully adequate for lesser wind and thunderstorm conditions. Another concern in mobile home developments is the closeness of the units which causes additional damage. When one home is destroyed by the winds, the debris is forced into the next subsequent unit and thereby weakening them in a domino type effect, increasing both the loss to property and the residents. Every mobile home park of 10 or more lots which is constructed after March 15, 1999, shall be provided with above or below-grade storm shelters that conform to the following requirements:
      A.   A minimum floor area of 12 square feet shall be provided for each lot located in the mobile home park.
      B.   Shelters shall be centrally located to provide a minimum travel distance of not more than 600 feet from any mobile home space. It may be necessary to provide more than one shelter.
      C.   Shelters shall not be located in flood prone areas.
      D.   Shelters shall be designed and constructed to meet all applicable requirements of the Americans with Disabilities Act (ADA).
      E.   Shelters shall be designed by a licensed structural engineer or architect and built in accordance with plans sealed by said structural engineer or architect.
      F.   A shelter may be utilized for other purposes which are allowed as accessory uses in this district; with the exception that the required minimum floor area shall not be infringed, nor shall the function of the structure as a storm shelter be limited in any way.
      G.   Shelters shall remain accessible at all hours.
      H.   For any addition of 10 or more lots to any existing mobile home park, a storm shelter which complies with the general requirements of this chapter shall be provided to serve such additional lots. For any addition of fewer than 10 lots to an existing mobile home park which otherwise complies with the requirements of this section, there is no requirement that an additional shelter be provided to serve such additional lots. Provided, however, that when two or more such additions occur, which result in a cumulative addition of 10 or more lots, a storm shelter shall be provided to serve such additional lots.

168.06 R-5 PLANNED UNIT DEVELOPMENT (P.U.D.).

   The R-5 District is intended and designed to provide a means for the development of large tracts of ground on a unit basis, allowing greater flexibility and diversification of land uses and building locations than the conventional single lot method provided in other sections of this Zoning Code. It is the intent of this section that the basic principles of good land use planning, including an orderly and graded relationship between various types of uses, be maintained and that the sound zoning standards as set forth in this Zoning Code and statutes concerning population density, adequate light and air, recreation and open space, and building coverage be preserved. Planned Unit Developments shall be permitted on any five acre or larger tract of land that has been zoned or rezoned for P.U.D. purposes by the Council.
   1.   Principal Permitted Uses. Buildings and permitted conditional uses shall be used only for residential purposes; occupant garages, occupant storage space, and similar accessory uses; non-commercial recreational facilities, and community activities, including churches and schools, with the following exception; on a tract of land in excess of 80 acres or more, up to five percent of the total net area may be developed for commercial uses such as those found in the C-1 classification district. The following is a description of permitted uses:
      A.   One-family dwellings, to include manufactured homes in accordance with the following definition: Manufactured home, provided it is located and installed according to the same standards for a foundation system, setback, and minimum square footage which would apply to a site-built, single-family dwelling on the same lot. Manufactured home means a structure built according to construction standards promulgated by the United States Department of Housing and Urban Development under authority of 42 U.S.C. Sec. 5403.
      B.   Two-family dwellings.
      C.   Multiple-family dwellings, including row housing cooperative apartment houses and condominium units.
      D.   Churches, cathedrals, temples, and similar places of worship, provided that all principal buildings be set back a minimum of 50 feet from all property lines.
      E.   Museums, libraries, parks and playgrounds, community centers, and similar uses operated by the City.
      F.   Golf courses, country clubs, tennis courts, and similar recreational uses, provided that any such use not be operated primarily for commercial gain.
      G.   Public and parochial schools, elementary and secondary, and other educational institutions having established current curriculum the same as ordinarily given in the Southeast Polk Public School System, but excluding boarding schools, nursery schools, and childcare centers, provided that all principal buildings are set back a minimum of 50 feet from all property lines.
      H.   Any use that is approved and made a part of the Development Plan, subject to any conditions attached thereto, shall be permitted.
   2.   Permitted Accessory Uses.
      A.   Uses of land or structures customarily incidental and subordinate to one of the principal permitted uses, unless otherwise excluded.
      B.   Temporary buildings for uses incidental to construction work, which buildings shall be removed upon the completion or abandonment of the construction work.
      C.   Swimming pools when enclosed by a non-climbable barrier at least six feet in height, and residential swimming pools when enclosed by a non-climbable barrier at least four feet in height.
      D.   TV dish antennas in accordance with Chapter 167.11.
   3.   Permitted Conditional Uses.
      A.   Home Occupations. A Conditional Use Permit must be applied for and received from the Board of Adjustment for a home occupation which does not meet the requirements set forth in Section 167.15.
      B.   Communication towers (freestanding type), see Section 167.12.
      C.   Communication towers of the building-supported type, see Section 167.13.
      D.   Wind Energy Conversion Systems (WECS), see Section 167.14.
      E.   Model Home. Shall not be operated at any time, other than between the hours of 9:00 a.m. to 7:00 p.m. on Monday through Saturday and 12:00 p.m. to 5:00 p.m. on Sunday. These hours may be reduced by the Board of Adjustment as a condition of an approved Conditional Use Permit. This use does not include offices for contractors, which are not allowed in residential zoning districts. A model home Certificate of Occupancy is required for the term of the conditional use. A Conditional Use Permit for a model home may be allowed for up to an 18-month period.
   4.   Bulk Regulations. Although a P.U.D. is intended to promote and permit flexibility of design and thereby may involve modifications of conventional regulations or standards, certain requirements which are set forth below shall be applied to ensure that the development is compatible with the intent of this chapter. Height, setback, bulk, and other requirements set out in the Development Plan shall constitute the basis for and become the zoning requirement for that particular P.U.D., provided that refinements may be made through final plan approval, if not defined as a substantial modification. In addition, the following minimum requirements shall be observed.
      A.   The minimum lot and yard requirements of the original zoning designation of the development need not apply. The Council may require open space or screenings be located along all or a portion of the development boundaries.
      B.   The height requirements of the zoning district directly adjacent to the development boundary shall apply within 125 feet of the development boundary and land.
      C.   All public streets, water mains, sanitary sewer, and storm sewer facilities shall comply with appropriate ordinances and specifications of the City.
      D.   “Common land”, as referred to in this section, refers to the land retained in private ownership for the use of all residents of the development, or to land dedicated to the general public.
      E.   Any land gained within the development because of the reduction in lot sizes below minimum Zoning Code requirements shall be placed in common land to be dedicated to the City or retained in private ownership to be managed by a homeowner’s association.
      F.   The requirements of this Zoning Code relating to off-street parking and loading shall apply to all R-5 Districts.
      G.   The final plan shall comply with the density requirements set forth in the Development Plan, but shall in no case exceed 20 units per acre.
      H.   Project phases shall be substantially and functionally self-contained and self-sustaining with regard to access, parking, utilities, required open space, screening, and transitional elements and other support features, and be capable of supporting required operation and maintenance activities; temporary provisions, such as turnarounds or access easements, may be required for this purpose; the initial phases generally should not be comprised of the most intensive portions of the P.U.D., unless the City concurs this is the most feasible means of developing the property in terms of access, sewer service, or similar physical constraints, or will permit earlier development of common amenities.
      I.   Attention shall be given to mitigation of existing or potential land use conflicts through proper orientation, open space, setbacks, landscaping and screening, grading, traffic circulation, and architectural compatibility. It is the intent of this chapter to recognize that appropriate use of the design techniques will provide the require mitigation, and thereby eliminate the need for certain conventional regulations or standards. As examples and not requirements: orienting views, access, and principal activities away from the land use needing protection, placing those least compatible activities farthest from the common boundary and those most compatible nearest, can create an effective buffer; setbacks in conjunction with landscaping can mitigate conflicts by providing a visual buffer, controlling pedestrian access, softening visual contrast by subduing the differences in architecture and mass, and reducing heat, and dense landscaping can reduce the width of physical separation needed for such purposes; proper grading will control drainage, can alter views and subdue sound, and channel access; fences, walls, and berms will channel access and control visual, sound, and light pollution; proper architectural use of color, bulk, materials, and shape will enhance compatibility and reduce contrast, although details added to the building for aesthetic purpose without consideration to form and surroundings may be detrimental rather than helpful; and proper design of pedestrian ways, streets, and points of congestion and safety hazards, and help prevent introduction of noise, pollutants, and other conflicts into areas with less intensive land use. Other techniques may also be used.
      J.   There shall be a minimum setback of 20 feet for any garage whose opening faces the street.
      K.   Permanent care and maintenance of open space, recreation amenities, and other common elements shall be provided in a legally binding form. Any of these items, not dedicated to the City or held in single ownership, will require the submittal of proposed bylaws of a homeowner’s association fully defining the functions, responsibilities, and operating procedures of the association. The applicant shall file the proposed documents governing the association for review by legal counsel for compliance with the following requirements at the time the final plat or site plan is filed;
         (1)   Membership shall be mandatory for each home buyer and any successive buyer.
         (2)   The open space restrictions shall be in perpetuity, or automatically renewable, and shall not terminate except by approval of both the homeowners’ association and the City.
         (3)   The homeowners’ association shall be responsible for liability insurance, local taxes, and the maintenance of recreational and other facilities.
         (4)   Homeowners shall pay their pro rata share of the cost or the assessment levied by the association shall become a lien on the property.
         (5)   The association shall be able to adjust the assessment to meet changes as needed.
         (6)   No change in open space use or dissolution of homeowners’ association shall occur without approval by the City.
         (7)   Additionally, the proposed bylaws shall include, but not be limited to, the following provisions:
            a.   Automatically extending membership in the association to all owners of dwelling units within the development;
            b.   Limiting the uses of the common property to those permitted by the final development;
            c.   Granting to each owner of a dwelling unit within the development the right to use and enjoyment of the common property;
            d.   Giving every owner of a dwelling unit voting rights in the association; and
            e.   If the development will combine rental and for-sale dwelling units, stating the relationship between the renters and the homeowner’s association and the rights renters shall have to the use of the common land.
      L.   Private open space shall be provided adjacent and accessible to each dwelling consisting of balconies, deck, or yard. Required open space on the ground level shall generally have a minimum dimension of 15 feet and minimum area of 400 square feet, and one-half of the required area shall not exceed a slope of five percent. Private open space for dwelling units located entirely above the ground floor shall generally have a minimum dimension of six feet and minimum area of 60 square feet.
      M.   Performance bonds may be required to ensure completion of recreational amenities provided in lieu of public facilities, or for mitigating elements such as screening or public improvements.
      N.   Except where the City agrees to other arrangements, a P.U.D. shall be comprised of a single owner, or a group of owners acting as a partnership or corporation with each agreeing in advance to be bound by the conditions which will be effective in the P.U.D.
      O.   Covenants to run with the land, in favor of the City and all persons having a proprietary interest in any portion of the development premises, verifying that the owner of the land, or successors in interest, will maintain all interior streets, parking areas, sidewalks, common land, parks, and plantings which have not been dedicated to the City in compliance with City ordinances.
      P.   Any additional agreements required by the Council at the time of Development Plan approval.
      Q.   A final plat shall be submitted for each phase of the final plan. The subdivider shall also submit a site plan for that part of the final plan that is multi-family or commercial, per the Site Plan Ordinance. (See Chapter 171).
      R.   Signs in accordance with Chapter 159.
      S.   Basement Required. A basement, containing the square footage of at least 60% of the dwelling’s habitable first story square footage at the time of original Building Permit approval, is required in all single-family detached dwellings. This section applies to all R-1, R-2, R-3, R-5 District lots within preliminary plats approved after January 1, 2026.
(Paragraph S – Ord. 10-20-2025 #02 (679) – Nov. 25 Supp.)
   5.   Procedure.
      A.   Pre-application Conferences. In order to eliminate unnecessary expenditures of time and money, the developer shall first schedule a pre-application conference with the Community Development Director, who shall involve representatives of other departments as deemed appropriate. The Community Development Director may require submittal of a generalized sketch plan providing such information as follows:
         (1)   Location and size of the overall site, and of the individual types of development of uses proposed within the site.
         (2)   Existing topography, indicating major earth-work areas, stormwater runoff and detention considerations, floodplains, and any problem areas.
         (3)   Existing tree masses and other geological and environmentally important characteristics.
         (4)   Generalized vehicular and pedestrian systems and parking areas.
         (5)   Generalized building locations.
         (6)   Approximate gross density, and number and types of dwelling units in accordance with the Comprehensive Plan; approximate gross floor areas of commercial land uses, where permitted.
         (7)   Generalized utility line considerations with sanitary sewer capacity limitations so noted.
         (8)   Generalized public and private ownership boundaries, including common ownership areas, if any.
         (9)   Generalized building locations for small P.U.D. proposals.
   The Department of Community Development shall have 15 days in which to review and comment on the pre-application sketch plan. Following the Department’s review, the developer may request an informal consideration of the proposal by the Planning and Zoning Commission. Said consideration shall be non-binding on either party.
      B.   Rezoning or Development Plan Application. Following the pre-application conference, the applicant shall submit a petition for rezoning in accordance with standard City procedures for rezonings, accompanied by a Development Plan and related documents, as described in Subsection 6.
         (1)   The petition and Development Plan shall be referred to the Planning and Zoning Commission for study and report, and for public hearing as required by this chapter for rezonings. The Planning and Zoning Commission shall review the Development Plan for conformity to the standards of this section, and may approve the Development Plan as submitted; require the petitioner to modify, alter, adjust, or amend the Development Plan as deemed necessary to preserve the intent and purpose of this section to promote public health, safety, morals, and general welfare; or recommend that it be denied. The action of the Planning and Zoning Commission shall be reported to the Council, where upon the Council may approve or disapprove the petition and Development Plan as reported or may require such changes thereto as deemed necessary to effectuate the intent and purpose of this chapter.
         (2)   The Department of Community Development shall schedule all required public hearings as soon as possible after all required information has been submitted. The Planning and Zoning Commission shall report their findings to the Council in a timely manner. In the event they fail to take action within 60 days after the date of public hearing, the petitioner or anyone located within the notification area as defined for rezonings may request in writing that the Planning and Zoning Commission complete their considerations. The Planning and Zoning Commission shall then take action within the next 30 days and report their findings to the Council for consideration by the Council, unless the Council expressly grants the Planning and Zoning Commission additional time to complete negotiations, studies, or other items as necessary.
      C.   Final Plans. Final plans for the Planned Unit Development shall be comprised of site plans or preliminary and final subdivision plats as appropriate to the situation due to requirements of the site planning and subdivision ordinances or specific provisions of the Development Plan. Such site plans and plats shall contain all information and be processed in the manner set forth in said ordinances, in addition to complying with any specific provisions of the Development Plan, and shall generally comply with the development concepts outlined in the Development Plan. No public notice or hearing shall be required for Final Plans unless required by the Development Plan or caused to be required by the Planning and Zoning Commission or Council as deemed appropriate. Provided that deviation from the Development Plan may be permitted as refinements to the design and planning if not defined by this chapter as substantial modification requiring amendment to the Development Plan. Substantial modifications shall be submitted for approval by the Planning and Zoning Commission and Council.
         (1)   Final plans may cover all or part of the Planned Unit Development, provided that a final plan covering only a part of a P.U.D. is hereby defined as a phase irrespective of contrary provisions by the Development Plan and shall demonstrate the ability to be self-sustaining in terms of access, services, utilities, open space, economic viability, and other major consideration.
         (2)   If it is the desire of the petitioner, preliminary plat or final Site Plan approval may be obtained at the time of Development Plan approval by expressly declaring such intent and filing all information required by the subdivision and site planning ordinances. Final Site Plan approval shall not be granted for an unplatted parcel unless an accurate property survey is also filed as part of the preliminary plat, if a plat is required, or as a certified property survey in the event a plat is not required.
         (3)   The final plan shall include proposed housing, types of housing, locations, density, building clearances, and documents, per the bulk requirements section of this chapter, so that the Planning and Zoning Commission and Council can adequately review all aspects of the proposed P.U.D.
         (4)   Upon approval of final plans, building permits shall be issued in the same manner as for building permits generally. In any event where platting is required, no building permits shall be issued until the final plat is approved and recorded and all other requirements complied with. Final plans shall be binding on the petitioner, and any and all successors in title, so long as P.U.D. zoning applies to the land, unless amended in accordance with the procedures set forth.
      D.   Amendments or Modifications. Substantial modifications to the Master Plan shall be processed in the same manner as a rezoning and additionally shall comply with the application process for a P.U.D. as set forth in this chapter. Notice and public hearing requirements, and the effect of a denial shall be the same as for rezoning, provided that the notification area shall be those property owners proximate to the parcel covered by the amendment, as opposed to the entire P.U.D.
   Further provided that, in the event a requested amendment for a portion of the entire P.U.D. is denied, such action shall not create any limitations under rezoning procedure on the filling of an amendment to another portion of the P.U.D. having a substantially different notification area. Any ambiguities or disputes between this section and procedures for rezonings shall be resolved in favor of the more restrictive requirements.
         (1)   Substantial modifications are hereby defined to include, but are not limited to, the following: increased density; intensification of use by changing to a higher classification, with conventional single-family being the lowest classification and progressing to attached single-family, multiple-family, public facilities or uses, approved conditional uses, commercial (where permitted); addition of uses, or elimination of conditions or restrictions on a use or uses; increased floor area ratios, or other modifications considered probable to generate increased traffic, sewage, waste consumption, or other detrimental conditions; significant modifications to peripheral buffering or screening, setbacks, height, location of buildings, drives, or other improvements, which were intended for protection of proximate properties, provided that substitution of equivalent screening materials shall not be considered a substantial modification; modifications to the street pattern, such as that of major streets or continuations of existing streets which will have a demonstrable impact on traffic flow such as to effectively change the functional classification of the street; modifications to access which may lead to increased congestion, or to additional commercial or industrial traffic on a local residential street; or other changes deemed substantial by the Director of Community Development.
         (2)   Modifications to final plans shall follow the procedures of the site planning or subdivision ordinances, as appropriate, except in the case of a substantial modification as defined above.
   6.   Information Required on the Development Plan Application. The following information, plans, and maps shall be submitted as part of the application for a Planned Unit Development:
      A.   Names, addresses, and telephone numbers of owners, developer, and designer; name of development, date, north point, and scale;
      B.   Legal description of the P.U.D., and map of the boundary of the proposed P.U.D. as well as interior boundaries of proposed development phases, and of any existing separate ownerships;
      C.   Sufficient information on adjacent properties to indicate relationships to the proposed development, including such information as land divisions, land use, pedestrian and vehicular circulation, significant natural features or physical improvements, and drainage pattern;
      D.   Existing site conditions including contours at intervals sufficient to indicate topographic conditions (generally two feet), drainage ways and 100 year floodplains, floodways, heavy woods, or other significant natural areas, and existing structures;
      E.   General locations of proposed lots and attached residential, multiple family, commercial (where permitted), recreational facilities; further delineating areas with different uses or building types, and gross density per acre;
      F.   General location and size of areas to be dedicated or reserved for common open space, park, schools, recreation area, and similar uses, and how any private facilities are proposed to be maintained;
      G.   Existing and proposed general circulation systems, including streets, pedestrian ways, major off-street parking and loading areas, and major points of access;
      H.   Existing and proposed general sanitary and storm sewer systems, water mains, and drainageways;
      I.   Proposed development standards, including uses, density, floor area ratios for non-residential developments, lot areas and widths, setbacks, and exceptions or variances from general requirements of zoning and other ordinances;
      J.   Sewer usage computations in accordance with the criteria of the sewer district;
      K.   Treatment of transitional zones around the perimeter of the project for protection of adjoining properties, including setbacks and buffer areas, landscaping, fences, or other screening, height limitations, or other provisions;
      L.   A narrative or graphic explanation of the planning and design concepts and objectives the owner intends to follow in implementing the proposed development, including a description of the character of the proposed development; the rationale behind the assumptions and choices made; the compatibility with the surrounding area; and design considerations for architecture, engineering, landscaping, open space, and so forth;
      M.   A statement of intent with regard to selling or leasing all or portions of the proposed development;
      N.   Proposed energy conservation methods, such as siting or design of structures; and
      O.   Proposed phasing timetable.
   The Director may require any additional information which may be needed to evaluate the proposed P.U.D. on the basis of special or unforeseen circumstances, or may waive any of the above requirements if it is found that such information is unnecessary to properly evaluate the proposed P.U.D.
   The above information should be shown in a clear and logical manner in a legible scale. Sheet size should not exceed 36 inches by 48 inches. Generally, existing conditions should be illustrated on a separate sheet for the sake of clarity, although existing topography, access, utility, and sewer lines and other items that are appropriate for understanding the proposal should also appear on the proposed Development Plan. It is strongly recommended that an architect, landscape architect, and civil engineer be employed to prepare the plans.
   7.   Referral to Council. The Final Plan and required documents shall be reviewed by the Planning and Zoning Commission for compliance with the R-5 District standards and substantial compliance with the Development Plan. The Planning and Zoning Commission’s recommendations and report on the Final Plan shall be referred to the Council for final approval. The Final Plan, consisting of a final subdivision plat or site plan shall be approved by the Council before any building permit is issued.
   8.   Contingent Approval. The Council may make the approval of the Development Plan contingent upon the completion of construction and improvements within a reasonable period of time; provided, however, that in the determination of such period, the Council shall consider the scope and magnitude of the development project and any schedule of construction and improvements submitted by the developer. Failure to complete all construction and improvements within said period of time shall be deemed sufficient cause for the Council to rezone the unimproved property to the classification effective at the time of original submission of the Development Plan, unless an extension as recommended by the Planning and Zoning Commission and approved by the Council for due cause is shown. Any proposed change in the Development Plan, after approval by the Counci,l shall be resubmitted and considered in the same manner as the original proposal. The term “unimproved” property shall mean all property situated within a stage or stages of the final development plan upon which the installation of improvements has not been commenced.
   9.   Continuing to Second and Subsequent Stages. In no event shall the installation of any infrastructure improvements be commenced in the second or subsequent stages of the final Development Plan until such time as 90 percent of all improvements have been completed and approved by the City for any prior stage. In the event the first development phase has not commenced within two years after the date of rezoning, or if subsequent phases are delayed more than two years beyond the indicated development schedule, the developer shall file appropriate information detailing the reasons for the delay with the Department of Community Development. The Director shall review the circumstances and prepare report recommending appropriate action to be taken concerning the P.U.D.
   The Planning and Zoning Commission and Council shall review the matter, and may continue the P.U.D. zoning with revised time limits; require that appropriate amendments be made or action taken, such amendments to comply with the procedures of this section if deemed substantial; continue the P.U.D. zoning for part of the area, with or without revised time limits, and initiate rezoning or the remainder to an appropriate district; or initiate rezoning of the entire parcel to an appropriate district, provided that the rezoning shall not be to a zone more restrictive than that applied immediately prior to the rezoning to P.U.D. except after comprehensive planning analysis. The Planning and Zoning Commission and Council may schedule such public hearings as deemed appropriate. Approval of a final Site Plan or preliminary plat shall be deemed to commence development, provided that the permanent placement of construction materials shall have started and be proceeding without delay within two years after the date of Site Plan approval, and a Final Plat approved within one year after the date of preliminary plat approval in the event a Site Plan is not required. Failure to comply with this provision shall void the Site Plan and preliminary plat approvals, and make the P.U.D. subject to review as provided above. It shall be the responsibility of the developer to comply with all prescribed time limits without notice from the City.
   10.   Zoning Density of R-5 Districts. The zoning density of R-5 Districts shall be determined by the Planning and Zoning Commission recommendation as approved, or amended, or finally passed by the Council; and the density shall be established and interpreted by the administration of the Zoning Code upon the basis of the plan for the overall development of the tract as the plan is approved and filed with the Council on final passage. In determining the density of the R-5 District, it shall be considered what the zoning is of adjoining property and the use of adjoining property and density of adjoining property; however, this policy shall not be binding on the Council in setting the final density for the R-5 District zoned properties. In no case shall an average density be approved which exceeds 20 dwelling units per acre. Each parcel of real estate that is zoned R-5 District must have its density determined on the merits of each case. Any real estate zoned R-5 District prior to the enactment of the ordinance codified herein shall be bound by the density that is shown in the plans as accepted and approved by the Council for the development of said real estate.

168.09 C-3 PLANNED COMMERCIAL.

   The C-3 District is intended to provide for the development of shopping centers. For the purposes of this section, the term “shopping center” means a planned retail and service area under single ownership, management, or control characterized by a concentrated grouping of stores and compatible uses, with various facilities designed to be used in common, such as ingress and egress roads, extensive parking accommodations, etc. Since shopping center developments, whether large or small, have a significant effect upon the comprehensive plan for the development of the City, extensive authority over their development is retained by the Council and the Planning and Zoning Commission. Many matters relating to the shopping center’s design, its potential for success or failure, and its effect upon surrounding neighborhoods must be considered by the Council and Planning and Zoning Commission in order to be reasonably assured that the area will not eventually become blighted. It is further intended that, in the event of an applicant’s failure to construct a shopping center in accordance with a reasonable time schedule, the Council shall enact the necessary legislation to reclassify the area to another classification consistent with the surrounding neighborhood. Such action would also, because of the reduction in commercial zoning in a given area, provide conditions whereby it could be reasonable for the Council to classify other areas in the vicinity for shopping center use.
   1.   Procedures. The owner or owners of any tract of land comprising an area of not less than five acres may submit to the Council a petition requesting a change to the C-3 zoning district classification. The petition shall be accompanied by a plan for the commercial use and development of the tract for the purposes of meeting the requirements of this section and by evidence of the feasibility of the project and its effects on surrounding property, including each of the following:
      A.   A site plan defining the areas to be developed for buildings, the areas to be developed for parking, the location of sidewalks and driveways and the points of ingress and egress, including access streets where required, the location and height of walls, existing and proposed grades, the location and type of landscaping and the location, size and number of signs, type or style of architecture, building material, color, or other significant feature.
      B.   An analysis of market conditions in the area to be served, including types and amount of service needed and general economic justification.
      C.   A traffic analysis of the vicinity indicating the effect of the proposed shopping center on the adjacent streets.
      D.   A statement of financial responsibility to assure construction of the shopping center, including landscaping, in accordance with the plan and the requirements of this section.
   The Development Plan shall be referred to the Planning and Zoning Commission for study and report. The Planning and Zoning Commission shall review the conformity of the proposed development with the standards of the Comprehensive Plan, and with recognized principles of civic design, land use planning, and landscape architecture. The Planning and Zoning Commission may approve the plan as submitted or, before approval, may require that the applicant modify, alter, adjust, or amend the plan as the Planning and Zoning Commission deems necessary to the end that it preserve the intent and purpose of this Zoning Code to promote public health, safety, morals, and general welfare. The Development Plan as approved by the Planning and Zoning Commission shall then be reported to the Council, whereupon the Council may approve or disapprove said plan as reported or may require such changes thereto as it deems necessary to effectuate the intent and purpose of this Zoning Code.
   2.   Principal Permitted Uses. Uses permitted in the C-3 District shall include only the uses of structures or land listed in this section, provided however, the Council may consider any additional restrictions proposed by the owner.

   The C-7 District is intended to provide aesthetically pleasing and harmoniously designed developments that serve a larger regional trade area that extends well beyond the City. Importance and detail is to be given as to the developments layout, architecture, streetscapes, landscaping, and public spaces. The C-7 District, as designated on the Comprehensive Plan land use map, provide commercial establishments that offer a variety of goods and services to consumers. The C-7 District is primarily intended for establishments that have a large customer draw (e.g. regional pull), generate significant traffic and parking need, and require close access to arterial (or higher functional class) streets. High intensity uses that include large structures and sites are encouraged, as is redevelopment and infill. The C-7 District is oriented primarily to automobile traffic, although the design shall also include adequate facilities for pedestrians, bicyclists, and public transit. The C-7 District is a Planned Unit Development Commercial District. A Development Plan shall be reviewed and approved by the Council. The Development Plan shall be characterized by a planned or concentrated grouping of buildings and compatible uses, with various facilities designed to be used in common, such as ingress and egress roads, extensive parking accommodations, etc. Since regional commercial developments, whether large or small, have a significant effect upon the development of the City, extensive authority over their development is retained by the Council and the Planning and Zoning Commission. Many matters relating to the areas design, its potential for success or failure, and its effect upon surrounding neighborhoods must be considered by the Council and Planning and Zoning Commission in order to be reasonably assured that the area will not eventually become blighted.
   1.   Procedures. The owner or owners of any tract of land comprising an area of not less than 100 acres initially may submit to the Council a petition requesting a change to the C-7 District classification. Amendments may be allowed in as little as five-acre increments. The massing and clustering of similar and compatible uses shall be done to maximize and maintain synergy for maximum customer draw. The petition shall be accompanied by a plan for the commercial use and development of the tract for the purposes of meeting the requirements of this section and by evidence of the feasibility of the project and its effects on surrounding property, including each of the following:
      A.   A Development Plan (also known as a Design Criteria Manual) defining the areas to be developed for buildings, the areas to be developed for parking, the design and location of sidewalks and driveways and the points of ingress and egress, including access streets where required, the location and height of walls, existing and proposed grades, the location and type of landscaping and the location, size and number of signs, site and street lighting, type or style of architecture, building material, color, or other significant feature.
