A transitional buffer block of equal or lesser development density and similar height characteristics shall be provided where property in an office residential district abuts a subdivision containing residential uses that are located in an office residential or other residential district. The following shall apply to the regulation of a transitional buffer block:

(1)

A transitional buffer block shall be required in all office residential subdivisions that are subdivided or resubdivided after June 1, 2003. Subdivisions or development plans that received council approval by resolution or by agreement prior to June 1, 2003, shall be regulated under the standards in effect at the time of subdivision or development approval, and uses within the subdivision shall not be considered nonconforming as defined and regulated by this article.

(2)

A transitional buffer block shall not be required within a subdivision but shall be required where two subdivisions are adjacent or contiguous. The term "subdivision" is defined by article II, division 1, of this chapter. The term "adjacent" or "contiguous" is defined in section 10-2, but, for the purposes of this subsection, two subdivisions shall be considered adjacent or contiguous if separated by a public or private street.

(3)

The term "block" is defined by section 10-2122. For the purposes of this subsection, the term "street" within the definition of the term "block" shall include private roadways that function as joint access to a residential development. Outlots that are located along the subdivision boundary shall be considered part of the block for the purposes of this subsection.

(4)

A transitional buffer block shall be located along the entire subdivision boundary of the adjacent residential blocks. The transitional buffer block shall consist of uses or open spaces that conform to this subsection.

(5)

Residential uses within the transitional buffer block shall be developed to an equal or lesser density as the adjacent residential block. In no case shall this provision reduce the density of the transitional buffer block below the net permitted density that is defined by the minimum lot area in the R-1 district.

(6)

The number of dwelling units in each dwelling located in the transitional buffer block shall be equal to or less than the average number of dwelling units in the dwellings located in the abutting residential block.

(7)

The area and dimension of the transitional buffer block shall be at least equal to the area and dimension of the adjacent residential block. In no case shall this provision require a transitional buffer block that would be greater in area or dimension than a residential block resulting from the application of the zoning standards in the R-1 district. The maximum depth of the transitional buffer block shall not be required to be greater than 130 feet as measured between the subdivision boundary and the block boundary.

(8)

Environmentally sensitive areas, defined as slopes in excess of ten degrees for the purposes of this subsection, and public parks shall be considered conforming open spaces and may be considered a transitional buffer block if the slopes or parks are located along all or part of the subdivision boundary and are equal to or greater in area and dimensions as the abutting residential block as specified in subsection (7) of this section. The slope or park may be located in the abutting residential block or within the subdivision required to provide a transitional buffer block.

(9)

Structures in the transitional buffer block shall be at an equal or lesser building height as found in the adjacent residential block. If the adjacent residential block is vacant, the maximum building height in the transitional buffer block shall be equal to or less than the heights or structures depicted on the approved plans submitted for the development of the adjacent residential block. If no such plans were submitted for the adjacent vacant residential block, the maximum permitted building height shall conform to section 10-274.

(10)

Where nonresidential uses are proposed for the transitional buffer block, the uses shall be developed at a similar floor area ratio and building height as found in the abutting residential block. A transitional yard shall be provided per section 10-271, and parking areas screened in conformance with section 10-1740.
