V. DESIGN STANDARDS BY

BUILDING FORM

The design standards are written by Building Form. The design variables for each of the nine Building
Forms are divided into four categories: Lot, Site, Building Form and Building Activation. Design standards
are written for each of the four categories. For those Building Forms that are permitted in multiple
Areas, specific design standards are provided for each design variable based on Area. After the design
standards for one category are provided, an annotated model illustrates the previously presented design
standards. Annotations in each model correspond to the letter(s) shown on each design variable table.

The four categories that the design variables for each building form are divided into are described
below:

Lot
Standards in the “Lot” category are intended to ensure that a site is adequately sized and dimensioned
to accommodate a particular building form, consistent with the intent of the DROD Area in which it is
located. Lot dimension requirements help ensure that a consistent and compatible horizontal rhythm
of buildings is established along a public street and that a project with multiple units or buildings on
one lot does not appear overly dense in relation to residential properties nearby. Lot requirements are
particularly important in areas where single-family homes are prominent.

Where a site will be subdivided into more than one parcel (a potential situation for Rowhouse, Cottage
Court, Two-Family and 3-Plex/4-Plex/Mansion Apartment), lot design standards should be based on the
collective area of all parcels. Figures 4.1 and 4.2 illustrate a project site that remains 1 parcel, despite
the individual rowhouse units. Figures 4.3 and 4.4 illustrate a project site that was subdivided into
individual parcels based on units. While this project is subdivided, the lot design standards should still
be based on the collective area of all parcels.

Site
Standards in the “Site Design” category are intended to ensure that the arrangement and relationship
between various elements on a site have a positive impact on the property and the surrounding
neighborhood. Site standards identify where buildings, parking and other elements should be located
on a site to promote a visually cohesive neighborhood, establish a rhythm of buildings along a street,
minimize the visual impact of parking and garages on the neighborhood and ensure that sufficient
light, air and privacy are preserved between adjoining properties. They also promote efficient and safe
circulation of pedestrians and vehicles, as well as a minimization of pedestrian/vehicle conflicts.

Where a site will be subdivided into more than one parcel (a potential situation for Rowhouse, Cottage
Court, Two-Family and 3-Plex/4-Plex/Mansion Apartment), site design standards should be based on the
collective area of all parcels. Figures 4.5 and 4.6 illustrate a project site that remains 1 parcel, despite
the individual rowhouse units. Figures 4.7 and 4.8 illustrate a project site that was subdivided into
individual parcels based on units. While this project is subdivided, the site design standards should still
be based on the collective area of all parcels.

Building Form
Standards in the “Building Form” category are intended to ensure that the basic parameters of a
building’s 3-dimensional volume are articulated and shaped to fit with the intent of a given DROD
Area. Requirements focus on the basic scale and dimensions of a building “envelope”, including overall
