Section 23-3-2(H): RM-10: Low-Density Multifamily Residential District (H) RM-10: LOW-DENSITY MULTIFAMILY RESIDENTIAL DISTRICT 123 The Low-Density, Multifamily Residential (RM-10) District is established and intended to accommodate principally multifamily dwellings at relatively low urban densities, as well as a variety of other dwelling types (including live/work dwellings, single-family attached or townhouse dwellings, two-family dwellings, three- to four-family dwellings, and detached single-family dwellings), and limited nonresidential uses that complement urban residential development (e.g., parks, places of worship, and schools). RM-10 zoning is generally appropriate for established low-density multifamily developments and areas near and conveniently accessible to business areas and activity centers designated on the comprehensive plan s future land use map.

Section 23-3-2(I): RM-20: Medium-Density Multifamily Residential District (I) RM-20: MEDIUM-DENSITY MULTIFAMILY RESIDENTIAL DISTRICT 124 The Medium-Density, Multifamily Residential (RM-20) District is established and intended to accommodate principally multifamily dwellings at moderate urban densities, as well as a variety of other dwelling types (including live/work dwellings, single-family attached or townhouse dwellings, two-family dwellings, three- to four-family dwellings, and single-family detached dwellings), plus limited nonresidential uses that complement and serve urban residential neighborhoods (e.g., parks, places of worship, schools, and retail and service uses meeting everyday needs of nearby residents). RM-20 zoning is appropriate for established medium-density multifamily developments and areas near and conveniently accessible to regional business areas and activity centers designated on the comprehensive plan s future land use map.

We also propose simplifying dimensional standards to eliminate maximum side setbacks, express the height limit in feet rather than in both feet and stories (with the limit slightly increased to accommodate four-story buildings greater than 45 feet high), and express minimum rear setbacks as a distance rather than as both a distance and a percentage of lot depth. We suggest moving the increased height/setback requirements for buildings adjacent to single-family residential and historic districts to the transitional standards to be included in Article 23-6.

Fig. 23-3-2(J)(3): RM-30 Example Building Form 125 As discussed in the Diagnosis/Annotated Outline (p. 2-31), we recommend the current RM-25 district be modified to a RM-30 district that allows a density of 30 dwelling units per acre to better accommodate increasing demands for high-density residential development, reflect a more balanced range of multifamily districts, and avoid opening up inappropriate areas to commercial development merely to gain higher residential densities. Other than increasing the maximum density limit, this subsection largely carries forward the current LDO s provisions for the RM-25 district, expanding the district intent statement to emphasize the greater diversity of housing types suggested in the Diagnosis/Annotated Outline (p. 2-30) and to provide greater guidance as to location of RM-30 districts. We suggest simplifying dimensional standards to eliminate maximum side setbacks, express the height limit in feet rather than in both feet and stories (with the limit increased to accommodate eight-story buildings greater than 80 feet high), and express minimum rear setbacks as a distance rather than as both a distance and a percentage of lot depth. We suggest moving the increased height/setback requirements for buildings adjacent to single-family residential and historic districts to the transitional standards to be included in Article 23-6.
