    (2)    Open space or common land shall be an essential and major element of the plan.

    (3)     Establishment of PUD. A PUD may be approved, provided that all the provisions of this section are complied with, but approval is not mandatory, and PUD is not a use of right.

    (4)     Density of development.

The maximum density shall be calculated on the land area that remains after deducting all perimeter street right-of-way requirements as determined by city street standards and the major roadway plan.

The actual density of the PUD shall be determined by conditions specifically applicable to the site such as topography, the character of the surrounding property, traffic movement, or adequacy of public services.

When zoning on property is changed to PUD, the zoning district map shall designate the property as PUD, followed by a number  with up to one decimal place (e.g. 5.5)  which shall indicate the maximum allowable dwelling units per acre on that particular site.

    (5)     Building height. Buildings shall not exceed forty-five (45) feet in height, except that the applicant may request or the commission may recommend and the council may approve a greater maximum building height.

    (6)     Lot size. Lots shall not be less than 2,500 square feet for one-family detached dwellings, except that the applicant may request or the commission may recommend and the council may approve a smaller minimum lot size.  No minimum lot size requirement for all other housing types.

    (7)     Yards. There shall be a twenty-five (25) foot setback from all perimeter property lines of the PUD, except the setback from property lines other than street right-of-way shall be ten (10) feet for side yards and twenty (20) feet for rear yards when the PUD or portion thereof consists of one-family , one-family attached  or two-family dwellings. The setback is intended to be a landscaped buffer; however, driveways (but not parking) are allowed. The applicant may request or the commission may recommend and the council may approve modifications in the width of or use of the setback when unique conditions warrant such modifications.

         Other minimum setback requirements shall be as follows:  front yard abutting a perimeter street - twenty-five (25) feet; front yard abutting an interior street - twenty (20) feet for a garage or carport facing the street and fifteen (15) feet for other portions of the building; interior side yard - five (5) feet; exterior side yard on the street side of a corner lot - fifteen (15) feet; interior common wall - zero (0) feet; zero lot line - zero (0) feet on one side and ten (10) feet on the other side; and rear yard - twenty (20) feet.  There shall be no setback required from a common area as long as the common area is at least as wide as the required yard.  There shall be one (1) additional foot of interior side yard setback required for each additional foot of height for buildings over forty-five (45) feet. The applicant may request or the commission may recommend and the council may approve lesser minimum setbacks.

    (8)     Vision clearance. On any corner lot on which a front or side yard is required, no wall, fence, sign, or other structure or no plant growth of a type which would interfere with traffic visibility across the corner shall be permitted or maintained higher than three (3) feet above the curb level, within fifteen (15) feet of the intersection of the street right-of-way lines.

    (10)     Parking. The provisions of section 29-30, off-street parking and loading, shall apply , except the applicant may request or the commission may recommend and the council may approve a lesser parking requirement if, after considering the proposed use, the availability of other parking in the area (including parking on public streets) and other relevant factors, it is demonstrated that a lesser requirement is appropriate. The commission may recommend and the council may allow some of the required parking to be deferred.  This shall be done by noting such parking spaces on the plan as “future parking if needed”.  The future parking may be placed within landscaped areas, as long as the landscaped areas are in excess of the minimum area required to be landscaped.  The property owners shall establish additional parking spaces in the “future parking” area when directed to do so by the council.

    (11)     Homeowners association.

For PUDs or portions thereof consisting of one -family detached dwellings on individual lots or one -family attached dwellings on individual lots (except as specified below), the provisions of section 29-25 shall not apply; however, this requirement shall be met by depicting the proposed landscaping on a "typical lot".

     (13)    Lighting.  The provisions of Sec. 29-30(h)(5) shall apply.

    ( e )     Procedure for Establishing PUD Zoning:

    (1)    The first step in the approval process should be a concept review to discuss and document the proposal. The concept review is an informal discussion and review between the director of planning and development or his designee and the developer to discuss land use and development concepts, applicable regulations, and other concerns that may be raised.

    (2)    The second step shall be the submittal of a request for rezoning to PUD. Rezoning shall be done in accordance with section 29-34 of this chapter and shall be accompanied by a statement of intent. The statement of intent shall be a letter, signed by the applicant or his agent, containing the following information about the proposed PUD:

         d .     The maximum building height proposed.

         The commission and council may require other plans or data as they deem necessary to accompany the statement of intent.   The statement of intent shall become part of the ordinance approving the PUD zoning  and  shall be binding upon the owners, their heirs and assigns until such time as the council shall release such limitations on the use of the subject property under the procedures provided herein. The statement of intent is intended to provide guidance for any future revisions to the PUD development plan.

     (3)    The commission shall then hold a public hearing.  After the public hearing, the commission shall forward its recommendation to the council.

     (4)     The council shall approve, approve with conditions, or disapprove the PUD zoning request. An ordinance placing property in district PUD shall specify the uses allowed. Prior to a vote on an ordinance placing property in district PUD that contains conditions, the applicant shall be given an opportunity to:

     (f)    Procedure for Review and Approval of a PUD Development Plan:

    ( 1 )    After the rezoning to PUD, the applicant shall submit a PUD development plan, which is in conformance with the ordinance approving the PUD zoning, for a public hearing by the commission. The procedures for application, review and public hearing on a PUD development plan shall be the same as for the rezoning. After the public hearing, the commission shall forward the PUD development plan to the council with its recommendations. The council shall take action to approve, approve with conditions, or disapprove the plan.

        As an option, the applicant may submit a PUD  development  plan along with the petition for rezoning to PUD and statement of intent, in order to abbreviate the approval process.

    ( 2 )    The PUD  development  plan submittal shall include the following:

        a.    Name of the PUD.

        b.    A north arrow, scale, small location map, and the size of the site to the nearest one-tenth (0.1) of an acre.

        d.    The names of adjacent property owners of unsubdivided land and the names of adjacent subdivisions.

        e.    The existing topography of the site with contour intervals no greater than five (5) feet, and the specific location of the one-hundred-year floodplain, if applicable.

        f.     The location and maximum height of all buildings. In the case of one -family units  or one -family attached units on individual lots, this requirement can be met by use of building "envelopes" which show the portion of the lot within which structures may be located.

        g.    The location and number of parking spaces, drives, walkways, and the parking ratio.

        h.    The location and width of existing street rights-of-way, alleys, roads, railroad rights-of-way, and recorded easements; and the proposed location, width, name and grade for any new street.

        i.    The location of existing and proposed sanitary sewers, water mains, storm sewers and natural gas mains within or adjacent to the site.

        j.    The types of dwelling units, other uses, and proposed density of development.

        k.    The location and size of all areas to be conveyed, dedicated or reserved as common open space, public parks, pedestrian ways, recreational areas, school sites, and similar public or semipublic uses.

        l.    The location  and dimension  of the perimeter setback  and other building setbacks .

m.    Signature blocks for commission and council approvals on all exhibits considered part of the PUD  development  plan.

n.    A  conceptual  landscaping plan  showing the areas to be landscaped or preserved, the general types of landscaping materials (trees, shrubs, lawn, etc.) proposed for each area, and the percent of the total site to be landscaped or preserved.  A landscaping plan (including any tree preservation areas) which complies with the requirements of Section 29-25 and Chapter 12A may be submitted with the PUD development plan or at the time of application for a land disturbance or building permit.  

o.    The phasing of structures, streets and amenities within the development.

    ( 3 )    In addition to meeting the requirements stated in paragraph ( 2 ) above, the PUD development plan shall adhere to the objectives set forth in paragraph (a), Purpose, and paragraph (d), Standards and Criteria.

    ( 4 )    Approval of the PUD development plan shall be deemed as satisfying the requirements of the subdivision regulations for a preliminary plat, provided all those requirements have been met.

Such variances shall be considered along with commission and council review of the plan.

    ( 5 )    No building permit shall be issued for any construction in the PUD until a final subdivision plat for the property on which permits are requested has been approved.

    ( 6 )    From and after five (5) years following the date of approval of the PUD development plan by the council, the plan shall become null and void, provided construction has not commenced on any portion of the PUD site.

        Prior to expiration of the PUD development plan, the council may extend the time for a specified period. A request for a time extension must be made in the form of a letter signed by the property owner or his agent.

    ( 7 )    Minor changes to an approved PUD development plan may be authorized by the director of planning and development, but in no case shall the director be obligated to approve such changes. Such changes shall not constitute a substantial deviation from the approved PUD development plan.

        In determining whether or not the change is a substantial deviation from the approved PUD development plan, the director shall use, but is not limited to, the following criteria:

        a.    Does the revision comply with the original statement of intent?

        c.    Is the dwelling unit type (attached, detached, multi-family) being altered?

        d.    Is there a change in public or private infrastructure?

        e.    Is there a change in amenities such as landscaping, open space, common area or recreational facilities?

        f.    Is there a rearrangement of buildings?

         g.    Is there an increase or decrease in land use intensity such as building height, size or increase in parking area?

        h.    Is there a change in the use of any structure?

        i.    Is there a potential increase in traffic?

    ( 8 )    Changes, other than those considered minor by the director of planning and development, shall be submitted to the commission for a public hearing. The public hearing shall follow the same procedures outlined herein for a PUD development plan. After the public hearing, the commission may approve the revision to the PUD development plan. If, however, the change is considered by the commission to be a substantial deviation from the PUD development plan or the statement of intent, the commission shall forward the proposal to the council. The council shall approve, approve with conditions, or disapprove the proposed revision.

     (g)    Simplified PUD.  An application may be submitted for a simplified PUD District provided the application complies with the following conditions:

     (1)    Uses shall be limited to permitted uses in District R-1.

     (2)    The height and area regulations in District R-1 shall apply, except that the minimum lot size shall not be less than 5,000 square feet; the minimum lot width at the building line shall not be less than fifty (50) feet; and the minimum front yard and rear yard setback shall not be less than twenty (20) feet.

     (3)    The requirements of subsection (c) are complied with, except as specified above for lot size, lot width and front and rear yard setbacks, and unless a specific exception is requested and approved by the council.
