Sec. 2.1.2. Housing Options

Sec. 2.1.2. Housing Options aaron.sheppard… Tue, 05/23/2023 - 09:08
  1. Conventional Development Option (see Article 2.2. Conventional Development Option)
    1. Conventional is a pattern of residential development that provides a majority of property owners with substantial yards on their own property.
    2. Under the conventional option no preserved common open space is required and the minimum lot size is limited to the lot size for the respective district.
  2. Compact Development Option (see Article 2.3. Compact Development)
    1. A compact development permits a reduction in lot size for residential subdivisions in exchange for an increase in common open space. This allows for efficient residential subdivisions and ample amenity area for the residents.
    2. Open space thresholds are district-based and are listed in Sec. 2.3.1. For projects under these minimum open space thresholds, only the conventional option can be used.
    3. Applicants that choose the Compact Development option must set aside 20% of the total project area or the minimum district-based requirements, whichever is greater, as common open space. Requirements for the configuration, use and management of common open space are set forth in Article 2.5. Common Open Space Requirements.
  3. Conservation Development Option (see Article 2.4. Conservation Development Option)
    1. A conservation development trades smaller lot sizes (with reduced setbacks) and additional density in exchange for preserving common open space. This allows for more efficient layout of lots, streets and utilities, promotes a mix of housing and protects the natural character of an area through the preservation of open space, recreation areas, environmental features and scenic vistas.
    2. Open space thresholds are district-based and are listed in Sec. 2.4.1. For projects under these minimum open space thresholds, only the conventional option can be used.
    3. Applicants that choose to use the conservation development option must set aside 40% of the total project area or the minimum district-based requirements, whichever is greater, as common open space. Requirements for the configuration, use and management of common open space are set forth in Article 2.5. Common Open Space Requirements.
  4. Frequent Transit Development Option
    1. A Frequent Transit Area as designated in the City's Comprehensive Plan encourages density and growth in areas served by high-frequency transit, defined as bus or other transit service where the time between vehicles will be 15 minutes or less during peak service periods. The Frequent Transit Development Option permits higher- density development than the underlying zoning might otherwise allow.
    2. The Frequent Transit Development Option encourages transit-oriented development by allowing for smaller lot dimensions and site area per dwelling unit standards.

Sec. 2.1.3. Additional Housing Patterns

Sec. 2.1.3. Additional Housing Patterns aaron.sheppard… Tue, 05/23/2023 - 09:08
  1. Cottage Court (See Sec. 2.6.1.)
    A cottage court is a group of small detached houses, tiny houses, attached houses or townhouses (two-unit maximum per building) sharing a common courtyard. The central courtyard enhances the character of the area through the provision of consolidated open space. A cottage court may be developed on individual lots or with a common form of ownership.
  2. Detached House Conversions (See Sec. 2.6.2.)
    A detached house addition is when an existing detached structure is expanded and converted into an attached building or apartment building. Additional regulations are required for these conversions.
  3. Accessory Dwelling (See Sec. 2.6.3.)
    The Accessory Dwelling housing pattern provides for the development of one accessory dwelling unit on a lot with an existing Detached House or Tiny House as an accessory use to a principal use of Single-unit Living or on a lot with an existing Attached House or Tiny House as an accessory use to a principal use of Two-unit Living.
  4. Flag Lot
    A Flag Lot is an irregularly shaped property with a narrow portion of land fronting on a street where no buildings are permitted that provides access to a larger portion of the lot where buildings are permitted. The creation of a flag lot typically results in an adjacent residual lot with greater frontage along the same street. Flag lots promote efficient use of land for residences. In exchange for some alternative minimum dimensional standards, only Tiny Houses are permitted on flag lots. ADUs are not permitted on flag lots.
