      (1)   Intent. Open space subdivisions are intended to allow greater flexibility in design and development of subdivisions in order to provide for more efficient use of land, protect topographical or other natural features or amenities, permit common area and open space reservation and preservation in perpetuity, and reduce overall development costs. The provisions set forth promote imaginative design in the development of subdivisions, which allows for better utilization of the unique physical qualities of the site in order to preserve them for not only the subdivision residents, but the community as a whole. To accomplish this purpose, the following regulations and development incentives to the R-SF-1 District shall be available when employing the open space subdivision option.
      (2)   Applicability. In any subdivision within the R-SF-1 Districts, the primary plat of which is submitted for approval after 7-1-2000 in accordance with Ch. 193 of this code of ordinances may be developed as a open space subdivision in accordance with the provisions of division (D)(3) below and §§ 194.125 through 194.128 of this chapter.
      (3)   Development requirements.
         (a)   Subdivision area (minimum size of a subdivision). There shall be a minimum of five acres required for the development of a open space subdivision. The tract of land to be divided shall be in one ownership or shall be the subject of an application for primary plat approval filed by the owners of the entire tract. The tract shall be developed as a unit and in the manner approved.
         (b)   Subdivision density. The overall maximum density of the proposed open space subdivision shall remain the same as that permitted by developing the same tract into developable lots in full compliance with the applicable underlying residential district regulations, Ch. 193 of this code of ordinances and any other applicable regulations.
         (c)   Project open space. The total land area saved by using this provision shall be put into project open space, per division (E) below.
   (E)   Waiver of development requirements in the R-SF-1 District for open space subdivisions. Individual lots with an overall subdivision that receives development plan approval from the Plan Commission to be developed as a open space subdivision pursuant to this section and §§ 194.125 through 194.128 of this chapter, may be granted a waiver of the development requirements of the R-SF-1 District to the extent permitted below:

      (2)   The development of such open space shall be subject to the following additional requirements.
         (a)   The open space shall be equivalent to or more than the total reduction in lot area. At least 75% of the total amount of open space shall consist of land areas which are at least 50 feet wide.
         (b)   The open space created by the development of the tract as a open space subdivision shall further be provided in such a manner that it is accessible:
            1.   To residents of the open space subdivision and their guests, by way of sidewalk, footpath or combined walkway/bikeway; and
            2.   For maintenance.

         (d)   No over head transmission line easement may be used in calculation of required open space.
      (3)   Open space shall be calculated by taking the total land area within lots contained in sketch plan one (as outlined below) and subtracting the total land area within lots contained in sketch plan two (as outlined below).
   (G)   Procedures for open space subdivision approval; plan documentation and supporting information.
      (1)   Plans. Prior to applying for primary plat approval, the petitioner shall submit two plans for the tract proposed for an open space subdivision for review by the Building Commissioner.
         (a)   A sketch plan shall depict the development of the tract in full compliance with all use and development standards of the applicable underlying residential district and Ch. 193 of this code of ordinances. This sketch plan shall be used to determine the maximum number of developable lots possible on the tract and set the density of that development.
         (b)   A site plan shall depict the development of the tract as an open space subdivision. The density of the overall development (total number of lots) shall be no greater than that permitted by the development of the tract depicted in the sketch plan. Documentary evidence of the provision of open space in a manner and amount equal to or in excess of that required by this section shall be proved either in written format or in tabular format incorporated into the site plan.
      (2)   Building Commissioner review.
         (a)   The Building Commissioner shall compare the two plans noted above to determine the appropriateness of the open space subdivision layout for the tract. In determining the appropriateness of the open space subdivision’s layout, the Building Commissioner shall look for the following attributes:
            1.   Protection of unique topographical features on the tract, including, but not limited to, slopes, streams, wooded areas and other natural features;
            2.   Protection and preservation of wooded areas, individual trees of significant size, wetlands or other environmentally sensitive features;
            3.   Development of common open space and recreational areas accessible to residents of the open space subdivision including provisions for walkways and bikeways;
            4.   More efficient use of land;
            5.   Innovative residential environments;
            6.   Minimization of the alteration of natural site features by the design and location of individual lots, streets and buildings. Diversity and originality in lot layout and individual building design shall be encouraged to achieve the best possible relationship between the development and the tract of land on which it is located;
            7.   Relationship to surrounding properties, improvement of the view from and of buildings; and
            8.   Minimization of the land area devoted to motor vehicle access shall be encouraged through the arrangement and location of individual lots, streets and buildings.
         (b)   The Building Commissioner shall further review the proposed open space subdivision to ensure that it shall be constructed, arranged and operated so as not to interfere with the development and use of surrounding properties in accordance with the applicable residential district regulations, to include any necessary transition along the perimeter of the development with other abutting single-family residential districts. In review of the proposed open space subdivision, the Building Commissioner may consult with the town’s Engineer or other appropriate health and safety officials to ensure that all fire and safety issues are addressed.
         (c)   The Building Commissioner shall provide his or her findings in writing to the petitioner, with a copy forwarded to the Plan Commission. The petitioner may then proceed with the filing of a petition for primary plat approval, which shall further serve as a petition for development plan approval. The primary plat filed shall be in substantial compliance with the site plan submitted to and reviewed by the Building Commissioner or may be revised to address or correct any deficiencies outlined in writing by the Building Commissioner. The petition for a primary plat approval, and subsequent legal notice of the public hearing regarding the petition, shall indicate clearly that the petition is for primary plat and development plan approval for an open subdivision.
      (3)   Plan Commission consideration.
         (a)   The Plan Commission shall make a disposition on the petition for development plan separately from the petition for primary plat approval for a open space subdivision in compliance with this chapter, Ch. 193 of this code of ordinances and the rules of procedures of the town’s Plan Commission.
         (b)   All petitions for secondary plat approval for a open space subdivision shall comply with the primary plat approved by the Plan Commission and any commitments or conditions associated with its approval.
      (4)   Findings. The Plan Commission may approve a development plan (and thereby grant the waivers requested by the petitioner) indicating compliance with this section and §§ 194.125 through 194.128 of this chapter only upon finding that:
         (a)   The use or value of area properties shall not be adversely affected;
         (b)   The proposed development shall be in compliance with the applicable general requirements for open space;
         (c)   The proposed development is appropriate to the site and its surroundings; and
         (d)   The proposed development is consistent with the intent and purpose of this chapter.
      (5)   Existing perimeter street lots.
