§ 3.1.4. Summary of development standards by lot/building types.  


Latest version.
  • The following summary and table 3.1.4A further illustrates the development standards for the various lot/building types.

    A.

    Dimensional requirements for each lot/building type: Table 3.1.4A provides dimensional requirements that apply to all lots of each designated lot/building type. These requirements supersede any contradictory requirements in other codes. If additional lot types are proposed during the application process, comparable dimensional requirements must also be proposed. Changes may also be proposed to the dimensional requirements in table 3.1.4A for a designated lot type. Administration of the appropriate jurisdiction will decide to accept, modify, or reject such dimensional requirements during the approval process based on its determination as to the consistency of the dimensions with the planning, design, and compatibility principles set forth in the regulatory plan and the development districts (in accordance with article 1.0).

    B.

    Frontage percentages: Frontage percentage is the percentage of the width of a lot that is required to be occupied by its building's primary façade. Table 3.1.4A provides minimum and maximum frontage percentages for each lot type. In the mixed-use commercial district, the town center district and the general neighborhood district up to 50 percent of the width of the primary façade may be counted as meeting the frontage percentage requirement even though it may be set back up to ten feet further from the street than the primary façade's principal plane providing that the said ten feet is dedicated to outdoor public/private space and open to the sidewalk for uses such as outdoor dining. The location of the primary façade's principal plane is not changed by façade extensions—frontages—such as bay windows, awnings, porches, balconies, stoops, colonnades, or arcades, or by upper floors that are closer to or further from the street. The width of a porte-cochere may be counted as part of the primary façade.

    C.

    Build-to lines and setback lines standards for all lot/building types:

    1.

    Build-to and setback lines distinguished:

    a.

    A build-to line identifies the precise horizontal distance (or range of distances) from a street that the front of all primary structures must be built to, in order to create a fairly uniform line of buildings along streets. Lot/building types specify build-to lines for street frontages.

    b.

    A setback line identifies the minimum horizontal distance between a property line and the nearest point of all structures, in order to ensure a minimum area without buildings. Lot/building types specify setback lines for side and rear property lines.

    2.

    General requirements for build-to lines:

    a.

    Build-to lines are illustrated conceptually on the building placement diagrams with each of the lot/building types.

    b.

    Where a build-to line is specified as a range (for instance, five to ten feet, this means that building fronts must fall within that range of distances from the front property line. Where there is a range, the front façade does not have to be parallel to the street or in a single plane, as long as the front façade remains within the range.

    c.

    At least 75 percent of the building frontage is required to align with the build-to line. The remaining 25 percent may be recessed up to ten feet behind the build-to line, for instance to provide recessed pedestrian entrances or simply for architectural diversity.

    d.

    Build-to lines are subject to adjustment to maintain visibility for vehicles exiting onto primary streets.

    i.

    Required visibility triangles must be maintained on both sides of intersecting streets and exiting driveways or to provide equivalent visibility.

    ii.

    Within these visibility triangles, no buildings, shrubs, or low-hanging tree limbs may obstruct visibility between the height of two feet and six feet above ground. However, visibility triangles are not required at intersections with roundabouts or all-way stop signs.

    e.

    Upper floors are encouraged to remain in the same vertical plane as the first floor. Awnings, canopies, balconies, bay windows, porches, stoops, arcades, and colonnades are allowed on building exteriors provided that they comply with the frontage standards.

    f.

    Build-to line requirements shall take precedence over any buffer or setback requirements imposed by other portions of this code.

    3.

    General requirements for setback lines: Minimum setbacks from property lines are defined for each zoning district.

    D.

    Building height: Table 3.1.4B shows building heights in the format of lot types by development district with the height minimum (stories/feet) and maximum (stories/feet) inclusive of required finish ground floor heights (30 inches), and plus additional height for allowable parapets.

    E.

    Wide buildings: The lot/building types allows a variety of buildings to be as wide and deep as the entire block face. When one of these wide buildings is placed directly across a street from significantly narrower lots, the principal façade of buildings on these lots must be varied with a change of architectural expression that reflects the widths of the narrower lots. These changes in expression may be a vertical element running from sidewalk to roof, a change in fenestration or style, color, or texture, or a break in façade plane or roof line. These changes may be subtle or significant, but must soften the visual effect of very wide buildings directly across the street from narrower buildings.

    F.

    Story heights: The ground story of commercial and mixed-use buildings must be from 12 feet minimum to 18 feet maximum tall. Each story above the ground story in commercial buildings must be from ten feet minimum to 15 feet maximum tall. Story heights are measured from the floor to the bottom of the lowest structural member that supports the story above.

    G.

    Accessory buildings: Each of the following lot/building types are permitted accessory buildings per Table 3.1.5: institutional; civic; mixed-use building; apartment/condominium; townhouse; villa/attached; single family detached; estate; countryside tract; and farms. Accessory buildings to serve the small box retail/drive through building type are subject to review by the zoning administrator to confirm compliance with section 3.4.5.2. Accessory buildings for small lot retail/drive through building/lot types shall not cumulatively exceed the size of the principal building.

    One accessory dwelling unit per principal building may be allowed following the approval of a SUP for the farm building/lot types. Accessory dwelling units may not exceed the size limitations in table 3.1.4A and must maintain the same side yards as required for the principal building.

    H.

    Primary entrance/access: The primary entrance of every building must directly face a street or a civic space, except as noted in section 3.4.6.

    The following summarizes and further illustrates the permitted and conditional uses for the various lot/building types.

    A.

    Permitted uses: Table 3.1.5 identifies the permitted, conditional and not-permitted uses for each lot/building type.

    B.

    Accessory uses: Accessory uses and structures not listed in Table 3.1.5 are regulated in the same manner as the lot/building type would otherwise provide for each permitted use.

    C.

    Permitted uses for additional lot types: If additional lot types are proposed during the application process, comparable assignments of land uses must also be proposed. Administration of the appropriate jurisdiction will decide to accept, modify, or reject such assignments during the approval process based on its determination as to their consistency with the planning, design, and compatibility principles set forth in the regulatory plan and the development districts (in accordance with article 1.0).
