11.3.A.2 Front Yard Build-To Line Requirement   

a.  Within the residential districts of the Historic Urban Neighborhood Districts, the front yard build-to line is established by any one (1) of the following methods. A build-to line is an established setback line at which a structure is required to build. However, in no case may the front yard of a single-family or two-family dwelling exceed twenty (20) feet in the Historic Urban Neighborhood Districts.

i.  As of the effective date of this Ordinance, the current front yard of the existing structure may be set as the required front yard build-to line. When a structure is demolished, the demolition permit shall indicate the dimension of the front yard prior to demolition. The required front yard build-to line is that indicated on the demolition permit.

ii.  The required front yard build-to line indicated on the most recent survey or Sanborn maps.

iii.  The average of the front yard of the adjacent lots on either side may be used to establish the required front yard build-to line. Averaging is based on the two (2) adjacent lots or, in the case of a corner lot, two (2) neighboring lots on the same blockface. In the case of a lot configuration where only one (1) lot is available for averaging, the front yard build-to line is that of the adjacent lot. (See Figure 11-1: Front Yard Averaging)

b.  The applicant is permitted a plus or minus three (3) foot variation from a front yard build-to line established by any of the above methods.

c.  The required front yard build-to line is measured as the narrowest dimension from the front lot line to the principal structure. The measurement is taken from the building walls of the principal structure and does not include permitted encroachments or architectural features, such as uncovered porches, bay windows, steps, and stoops.

11.3.A.3 Corner Side Yard for Single-Family and Two-Family Dwellings   

a.  For single-family and two-family dwellings within the residential districts of the Historic Urban Neighborhood Districts, the corner side yard is established by any one (1) of the following methods.

i.  As of the effective date of this Ordinance, the current corner side yard of the existing structure may be set as the required corner side yard. When a structure is demolished, the demolition permit shall indicate the dimension of the corner side yard prior to demolition. The required corner side yard is that which is indicated on the demolition permit.

ii.  The required corner side yard may be that indicated on the most recent survey or Sanborn maps.

iii.  A minimum of ten percent (10%) of lot width.

b.  The required corner side yard build-to line is measured as the narrowest dimension from the corner side lot line to the principal structure. The measurement is taken from the building walls of the principal structure and does not include permitted encroachments or architectural features, such as uncovered porches, bay windows, steps, and stoops. 

11.3.A.4 Required On-Site Open Space   

All townhouse and multi-family dwellings shall provide at least one-hundred twenty (120) square feet of useable on-site open space per dwelling unit. This open space may be either private open space for the dwelling unit or common open space restricted to the use of residents of the townhouse or multi-family dwelling. Such open space shall meet the following requirements:

a.  Required open space shall have a minimum dimension of at least seven (7) feet on any side.

b.  Required open space shall be located on the same lot as the dwelling unit it serves.

c.  Required open space shall be outdoors and designed for outdoor living, recreation, or landscape, including areas located on the ground and areas on decks, balconies, galleries, porches, or roofs. For multi-family dwellings, when open space is above grade, such as a balcony or gallery, it may not be located over on-site surface parking areas.

d.  The required open space area may not be contiguous, but each open space area, whether common or private, shall comply with minimum dimensional standards of Table 11-2. Common open space areas shall be accessible to all residents of the subject development.

e.  When located at ground level, the required open space area shall be substantially covered with grass, live groundcover, shrubs, plants, trees, or usable outdoor hardscape features or amenities, such as seating areas, patios, or pools.

f.  Off-street parking and loading areas, driveways or required landscape for parking lots and screening do not satisfy open space requirements. Bollards, curbs, wheel stops, or other similar features shall be provided to ensure that required open space areas are not used for off-street parking or any other vehicular use.

g.  Mechanical equipment, dumpsters, or service areas are prohibited in required open space areas.

h. All required open space areas shall be located and designed to take advantage of sunlight and other climatic advantages of the site.
