a. The context area for the required street yard of the subject lot shall be the established street yards (as defined by the distance between the primary structure on each property and the edge of the right-of-way) on residential lots, including structures converted to nonresidential use, with residential zoning along the same block face.

For the purposes of this section, all lots on both sides along a cul-de-sac or other similar street section shall be considered a block face.

b. Vacant lots shall apply if the primary structure was demolished after January 1, 2006. GIS maps, demolition documents, and any available surveys shall be used to determine the street yard of the demolished building. If no documentation is available, then the minimum or maximum street yard of the zoning district, as applicable, shall be used.

c. Flag lots shall not be used for considering street yards. For flag lot yard requirements, see paragraph 6.12.5, Flag Lots.

a. The required street yard shall be any distance between the smallest and largest street yards within the context area. However, in no instance shall the smallest street yard be less than five feet.

Example: The subject infill lot (B) and four other lots with residential zoning make up the block face. One lot is undeveloped prior to January 1, 2006, and thus shall not be considered. The street yards along the block face of the three other lots are 10 feet (A), 15 feet (C), and 20 feet (D). Therefore, the required street yard for the subject lot (B) can be anywhere between 10 feet (the smallest) and 20 feet (the largest).

b. If there are fewer than two lots that qualify within the context area, the street yard requirement shall be that of the base zoning district.

c. For corner lots, one of the two street yards may be developed using side yard standards.

d. For detached duplexes using infill standards, only one building must have a street yard less than or equal to the largest street yard within the context area.
