(a) Purpose. This district is intended to provide for commercial and recreational activities that warrant special consideration due to their scale or potential impacts, or for certain sites due to their location or environmental characteristics. The major objectives of a C-P district are:

    (1)    To promote flexibility in the design and location of structures.

    (2)    To promote the efficient use of land and to facilitate a more economic arrangement of buildings, circulation systems, land uses and utilities.

    (3)    To ensure compatibility with surrounding areas.

    (4)    To encourage a higher quality of landscaping and sign control.

    (b) Permitted Uses. In district C-P, no building, land or premises shall be used and no building shall be hereafter erected, constructed, reconstructed or altered, except for one or more of the uses allowed by the ordinance placing the property in district C-P (for exceptions, see section 29-28, Nonconforming Uses, and section 29-31, Board of Adjustment). The commission shall recommend and the council, at the time of rezoning, shall designate the use or uses allowed for the applicant's property from the following uses:

One or more or all of the permitted uses in district C-1.

One or more or all of the permitted uses in district C-3.

Amusement parks, commercial baseball or other athletic fields, race tracks or fairgrounds.

Commercial picnic grounds and fishing lakes.

Machine shops.

Outdoor stage and concert facilities.

Plumbing, heating, air-conditioning, and electrical businesses, which may include related customary activities such as contracting, retail and wholesale sales and distribution.

    Temporary Shelter, subject to the following.

(1)    A zoning petition for a temporary shelter shall include information about the size and design of the structure, population groups served, length of stay permitted, maximum design capacity and support services provided.  These items shall be used to determine if the facility is appropriate for the neighborhood.

    (2)  A temporary shelter shall not be located within one thousand (1,000) feet of another temporary shelter.

(3)    The minimum lot area for a temporary shelter shall be 7,500 square feet. If a proposed temporary shelter structure is larger than 2,500 square feet of gross floor area  there shall be provided an additional 1,500 square feet of lot area for each additional 500 square feet of gross floor area within the structure.

(4)    The shelter shall submit a semi-annual report to the protective inspection division of the public works department stating maximum monthly occupancy level and support services provided by the shelter.

Travel trailer parks.

Warehousing and distribution facilities provided such facilities are ancillary to other allowed uses in the C-P District.

     The owner of property zoned C-P may apply for a change in the permitted use or uses of the property. Such application shall be treated as a request for rezoning.

    (c) Conditional Uses. Except as provided in section 29-21.3 there shall be no conditional uses in district C-P and the board of adjustment shall have no power to grant any conditional use permit for any property in district C-P.    The following uses shall be permitted in district C-P only after the issuance of a conditional use permit pursuant to the provisions of section 29-23:

    (d) Standards and Criteria. The following standards and criteria shall apply to all C-P developments:

    (1)     Lot size. No minimum requirements.

    (2)     Yards. Yards shall be provided as deemed necessary, based on the characteristics of each individual proposal, to provide compatible development.

    (3)     Building height. No specific maximum; however, building height shall be compatible with the surrounding area.

    (4)     Vision clearance. On any corner lot 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.

    (5)     Parking and loading.   The provisions of section 2930, offstreet parking and loading, shall apply, except that the Commission may recommend and the Council may approve a different parking requirement if, after considering the proposed use, the availability of other parking in the area (including parking on non-residential public streets) and other relevant factors, a different requirement is deemed appropriate.

    (6)     Screening. A permanent screen consisting of a masonry wall, wood fence, landscaping material, or combination thereof, at least eight (8) feet in height and, when a fence is used, not to exceed twelve (12) feet in height, shall be required where a lot in this district abuts residentially zoned land. The required screening shall have an opacity of at least eighty (80) per cent year around and, if landscaping is used, the eighty (80) per cent opacity and eight-foot minimum height shall be achieved within four (4) full growing seasons. In the event a masonry wall or wood fence is used, landscaping shall be placed between the wall or fence and the property line to form an ornamental screen. The required screening and landscaping shall be maintained in good order and not allowed to exist in a state of disrepair or death. If wood fencing is used, it shall be durable in nature and treated to prevent rapid deterioration. Failure to maintain the required landscaping and screening shall be considered a violation of this chapter.

    (7)     Drainage. A drainage system shall be designed to minimize the possibility of soil erosion and flood damage.

    (8)     Circulation. The traffic circulation system shall provide for the safe, convenient and efficient movement of goods and people with a minimum of conflict between various modes of travel. Provisions shall be made for pedestrian travel within the development and shall connect with existing pedestrian systems or allow for future extensions to activity centers outside the development (i.e., schools, parks, shopping areas, etc.).

    (e) Procedure for review and approval of C-P zoning and the development plan.

    (1)    The first step in 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 and the developer to discuss land use and development concepts, applicable regulations, and other concerns that may be raised.

    (2)    The applicant shall prepare and submit a request for C-P zoning to the commission for its review. The commission shall then hold a public hearing.

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

    (4)    The council, after a public hearing, shall take final action on the C-P zoning request and shall specify the uses allowed.

    (5)    After council approval of the rezoning, the applicant shall submit a development plan for review and approval by the commission. The development plan shall be processed in the same manner as a rezoning request. Advertising costs shall be at the applicant's expense. After the public hearing, the commission shall forward the development plan to the council with its recommendation. The council will then conduct a public hearing and take action on the plan.

    (6)    The development plan submittal shall include the following:

        a.    The name of the C-P development.

        g.    The location and height of all buildings. The minimum distance from buildings to perimeter property lines shall be shown or stated on the plan.

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

        i.    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.

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

        k.    A landscaping plan which complies with the requirements of chapter 12A.

        l.    A storm water management plan, which shall include provisions for erosion control during construction.

        n.    The proposed location and general description of signs not attached to structures on the site.

        o.    The proposed type and location of all on-site lighting.

    (7)    In addition to the above, an C-P development plan submittal shall include a set of design parameters which the director of planning and development shall use as guidance when considering future revisions to an approved C-P development plan. The design parameters shall be in the form of a letter and shall include the following:

    a.    The maximum gross square footage of building floor area on the site.

    b.    The minimum distance between any building and any adjacent property line or street right-of-way.

    c.    The maximum height of any building on the site.

    f.    The maximum number of freestanding signs on the site, the maximum square footage of sign surface area and maximum height of each.

    g.    The minimum per centage of the site to be maintained in landscaping.

        The design parameters shall become part of the ordinance approving the C-P development plan.

    (8)    Approval of the development plan shall be deemed as satisfying the requirements of the subdivision regulations for a preliminary plat, provided all those requirements have been met. Any variances to the subdivision regulations, proposed as part of the development plan shall be stated clearly on the development plan. Such variances shall be considered along with commission and council review of the development plan.

    (9)    No building permit shall be issued until the development plan is approved by the council.

    (10)    No building permit shall be issued until the property has been platted.

    (11)    No building or footing and foundation permit shall be issued until the site plan filed with the application for a building permit has been reviewed by the director of planning and development for compliance with the approved development plan.

    (12)    From and after two (2) years following the date of approval of a development plan by the council, the council, may, by a majority vote, withdraw approval of such development plan, provided development has not commenced.

    (13)    Minor adjustments to a development plan approved prior to November 18, 1996, may be authorized by the director of planning and development at his discretion. The director of planning and development shall notify the commission of any such changes.

    (14)    Changes to a development plan approved prior to November 18, 1996, 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 development plan. If, after the public hearing, the change is considered to be in substantial compliance with the approved development plan, the commission may approve the revision. If, however, the change is considered to be a substantial deviation from the approved development plan, the commission may recommend to the council that a revised development plan be required. The council shall then take action on the proposed revision without a public hearing. If the council determines that the proposed change is a substantial deviation from the approved development plan, a revision to the development plan shall be required. This revision shall be processed in the manner herein described for development plans. Advertising costs shall be at the applicant's expense. The revised plan shall not be approved unless findings determined by the council are reflected on the plan.

        In determining whether or not the change is a substantial deviation from the approved development plan, the commission and council may use, but are not limited to, the following criteria:

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

        b.    Is there a rearrangement of or change in the number of buildings?

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

        d.    Is there a change in amenities being proposed, such as landscaping or open space?

    (15)    Changes to a development plan approved after November 18, 1996, may be made to an approved C-P development plan subject to approval by the director of planning and development, provided that any such changes are within the limits set forth in the approved design parameters. Any proposed changes which exceed the limits of the design parameters shall be processed as a new C-P development plan with required public hearings before the planning and zoning commission and city council.

    (16)    The applicant may submit the development plan at the time of rezoning to C-P. Under this option, the development plan will be considered as part of the rezoning request.
