(a)

Purpose of the R Single-Family Detached Residence District. The R District is established to protect, promote, and maintain the development of single-family detached housing and limited public and institutional uses that are compatible with the surrounding residential neighborhood. The development standards and range of allowable uses for this district are designed to maintain a suitable environment for family living at the low density of development characteristic of the current pattern of development in the district, which consists of large lots with abundant open space. The R District includes one (1) sub-district which allows the same uses but provides bulk provisions that reflect the specific attributes of the development pattern that results in lot width and lot area that are less than that of the R District but still larger than that typically found in any R1 sub-district.

(b)

Purpose of the R1 Single-Family Detached Residence District. The R1 District is established to protect, promote, and maintain the development of single-family detached housing and limited public and institutional uses that are compatible with the surrounding residential neighborhood. The development standards and range of allowable uses for this district are designed to maintain a suitable environment for family living at the relatively low density of development characteristic of the current pattern of development in the district. The R1 District contains nine (9) sub-districts each of which allows the same uses but provides bulk and height provisions that reflect the specific attributes of the development patterns found in those sub-districts. Such attributes are described below.

(1)

The R1-A Sub-district contains predominantly single story and split-level homes developed since the 1950s.

(2)

The R1-B Sub-district contains residential development of a relatively low scale character having height and land coverage characteristics smaller than other areas.

(3)

The R1-C Sub-district contains a set of relatively uniform lots that tend to contain a mostly two (2) story homes located on a majority of lots smaller than found in other parts of the community.

(4)

The R1-D Sub-district contains predominantly two (2) story homes located on lots that range between fifty (50) and sixty (60) feet in width.

(5)

The R1-E Sub-district contains one (1) and two (2) story homes located on smaller lots, many less than fifty (50) feet in width, and accommodating smaller footprint buildings scaled to those lots.

(6)

The R1-F Sub-district contains a mix of homes built after the 1950s and containing primarily less than three (3) stories.

(7)

The R1-G Sub-district contains height and bulk provisions that typify the large home and lot development pattern found in the area roughly comprising the residential area abutting Chestnut, Ashland, Greenwood and Elmwood Streets east of Green Bay Road.

(8)

The R1-H Sub-district contains predominantly older homes, many of which are three (3) stories and are located on lots of fifty (50) to sixty (60) feet in width.

(9)

The R1-I Sub-district contains some of the smallest residential lots in the village and accommodates limited space between buildings. Development in this area fronts on narrow rights of way imparting a specific character to the neighborhood.

(c)

Purpose of the R2 Attached Residence District. The R2 District is established to protect, promote, and maintain the development of single-family detached and attached housing and limited public and institutional uses that are compatible with the surrounding residential neighborhood. The development standards and range of allowable uses for this district are designed to provide for residential living in areas that have a single-family residential character but are transitions between areas of commercial or multi-family uses and areas of predominantly single-family detached dwellings.

(d)

Purpose of the R3 Multi-Family Residence District. The R3 District is established to protect, promote, and maintain the development of multi-family housing and limited public and institutional uses that are compatible with the surrounding residential neighborhood. The development standards and range of allowable uses for this district are designed to provide for convenience and affordability in residential living, at densities characteristic of low-rise multi-family residential buildings.

(e)

Purpose of the R4 Multi-Family Residence District. The R4 District is established to protect, promote, and maintain the development of multi-family housing and limited public and institutional uses that are compatible with the surrounding residential neighborhood. The development standards and range of allowable uses for this district are designed to provide for convenience and affordability in residential living, at a density characteristic of high-rise multi-family residential buildings.

(Code 1993, § 20-8.1)

Table 8-1: Residential Zoning Districts Permitted and Special Uses lists permitted and special uses for the residential districts. A "P" indicates that a use permitted within that district. An "S" indicates that a use a special use in that district and must obtain a special use permit as required in Section 30-5.3 (Special Use). No letter (i.e., a blank space), or the absence of the use from the table, indicates that use is not permitted within that district.
