10.3.2 Zero Lot Line Development

  • A.
    Description. A zero lot line development is one in which houses in the development on a common street frontage are shifted to one side of their lot. This provides for greater usable yard space on each lot. These developments require that planning for all of the house locations be done at the same (subdivision) platting. Because the exact location of each house is predetermined, greater flexibility in site development standards is possible while assuring that single-dwelling character is maintained.
  • B.
    Applicability. Zero lot line developments are allowed for houses in the RHD, R-6, and R-8 Districts and all Planned Development Districts.
  • C.
    Procedure. Zero lot line developments are allowed by-right. Review for compliance with the standards of this section shall occur during the subdivision platting process. Restrictions that assure the minimum distance between houses and any required easements must be recorded on the plats of the applicable lots. Proof of such recordation must be submitted as part of the building permit application.
  • D.
    Setbacks. Notwithstanding any other requirements of this Zoning Ordinance, the side building setback on one side of a house in an approved zero lot line development may be reduced to zero (0) feet. This reduction does not apply to the street side setback or to the interior side setback adjacent to lots that are not part of the zero lot line project.
  • E.
    Additional Standards
    1. 1.
      Distance Between Houses. The minimum distance between all buildings in the development must be equal to two times the required side setback required by the underlying zoning district. A deed restriction must be recorded on the deed of each applicable lot to ensure continued compliance with this setback.
    2. 2.
      Eaves. The eaves on the side of a house with a reduced setback may project a maximum of 18 inches over the adjacent property line. In this case, an easement for the eave projection must be recorded on the deed for the lot where the projection occurs.
    3. 3.
      Maintenance Easement. An easement between the two property owners to allow for maintenance or repair of the house is required when the eaves or side wall of the house are within 4 feet of the adjacent property line. The easement on the adjacent property must provide at least 10 feet of unobstructed space between the furthermost project of the structure and the edge of the easement.
    4. 4.
      Privacy. If the side wall of the house is on the property line, or within three (3) feet of the property line, windows or other openings that allow for visibility into the side yard of the adjacent lot are not allowed. Windows that do not allow visibility into the side yard of the adjacent lot, such as a clerestory window or a translucent window, are allowed.

  • B.
    Applicability. The Traditional Design Option is an alternative set of standards for new single-family detached residential development of 50 acres or more in the R-1 zoning district, with frontage on at least one major arterial road (existing or planned). When in conflict with other Town regulations, including the Zoning Ordinance, the Design and Construction Standards Manual, The Subdivision and Land Development Regulations, etc. the Traditional Design Option shall take precedence.
  • C.
    Procedure. The Traditional Design Option is allowed by right. Review for compliance with the standards of this section shall occur during the subdivision review process. Proof of such recordation must be submitted as part of the Zoning Permit application. Individual building elevations required by Section 10.3.3.J.4 shall be submitted as part of the Zoning Permit application.

    9. 9.
      Applicants shall provide a typical street section with the application.

      Street cross-sections shall indicate the location of proposed street trees.
  • G.
    Open Space.
    1. 1.
      The Open Space regulations of this section require the establishment and maintenance of improved open space to provide adequate light, air and space to residents or occupants of all developments. These regulations require the establishment of a property owner association to be responsible for the maintenance of common improvements, as detailed in Section 8.3.6 of the Zoning Ordinance.
    2. 2.

        3. iii.

    10.4.1 Size and Dimension Standards, Generally

  • A.
    Establishment of Standards. In order to carry out the purpose and intent of this Zoning Ordinance, size and dimension standards for particular zoning districts are hereby established.
  • B.
    Application of Standards. The size and dimensions established by this Zoning Ordinance within particular zoning districts shall be minimum or maximum limitations, as appropriate to the case, and shall apply uniformly to each class or kind of structure or parcel of land, except as specifically provided herein. Where this Zoning Ordinance imposes greater restrictions upon the use of a structure or parcel of land than are imposed on such uses by any other town regulation or ordinance, the provisions of this Zoning Ordinance shall prevail.
  • C.
    Use, Occupancy and Construction. No building, structure or parcel of land shall hereafter be used or occupied, and no building or structure or part thereof shall hereafter be constructed, except in conformance with all size and dimension standards for the district in which it is located.
  • D.
    Requirements for One Use Not to be Used for Another. No part of a yard, open space area, or lot area required in connection with any building or use for the purpose of complying with this Zoning Ordinance shall be included as apart of a yard, open space or lot area similarly required for any other building or use, unless so authorized by this Zoning Ordinance.
  • E.
    Variances. Variances from these standards, excluding the maximum density and floor area ratio (FAR) limitations and as authorized by Sec. 13.2, may be granted by the Board of Zoning Appeals in accordance with the procedures of Sec. 3.13.

    • Effective on: 1/1/1901

    10.4.2 Minimum District Size

  • A.
    Generally. Where a minimum district size is specified for a given zoning district, no parcel of lesser size shall be so classified in any location in the town except by the Town Council acting on a rezoning application of its own initiation. Additional contiguous land may be rezoned to such classification if such an addition complies with any minimum standards established for enlarging the zoning district.
  • B.
    If No Minimum District Size. Where no minimum district size is specified, the minimum lot area and lot width requirements shall define the minimum district size.

    • Effective on: 1/1/1901

    10.4.3 Calculation of Density

  • A.
    Generally. In no instance shall the maximum residential density specified for a given zoning district be exceeded in the approval of any development, except as specifically authorized in this Zoning Ordinance. For residential districts maximum density shall be expressed as the number of dwelling units divided by the net area of the subject parcel.
  • B.
    Residential Density Calculation. For the purpose of calculating density, net area shall be calculated by subtracting all of the following from the gross land area of the subject parcel: (1) all lands within existing public rights-of-way (2) area within the 100-year floodplain and wetlands; (3) any area devoted to nonresidential uses, unless otherwise authorized by the Zoning Ordinance or Planned Development Ordinance and provided all other applicable town regulations are met; and (4) area classified as steep slopes.
  • C.
    Fractions. The maximum density figures of this Zoning Ordinance shall not be interpreted as a guarantee of density; other standards may work to limit density to figures lower than the stated maximum density of the underlying zoning district. In the determination of the maximum number of units to be allowed, the permitted number shall be made proportional to any fraction of an acre that is part of the development. Any fraction of a number shall be rounded down to the next whole number.
  • D.
    Mixed Residential. In mixed developments having both multi-family and single-family attached (townhouse) sections, density and any resulting active recreation facility requirements may be calculated separately for each respective dwelling category. See Article 9.

    • Effective on: 1/1/1901
