15 3.2.2 C - Neighborhood Street

Neighborhood Streets are used primarily in areas serving between 151 and up to 350 residential units, and where residential uses may be compatible with non-residential uses in a mixed-use context. They accommodate on-street parallel parking on both sides and feature two general travel lanes for vehicular use, including automobiles, bicycles, and occasional local transit or freight vehicles. Sidewalks are required on both sides of the street. Traffic calming design elements such as intersection bulb-outs can help to moderate vehicle speeds on Neighborhood Streets. Traffic calming design elements such as intersection bulb-outs and curb extensions/bump-outs can help moderate vehicle speeds on Neighborhood Streets, which are conducive to use of GSI practices including curbside bioretention, bioretention in bulb-outs and/or curb extensions, and permeable pavement sidewalks. Multi-Family Local Streets are intended to provide direct lot access and a relatively high level of on- street parking capacity in residential settings (Apartments and Townhomes). Two general travel lanes are present along with the allowance of a row of parking on each side in a parallel, perpendicular or angled configuration. Multi-family streets are to be used exclusively for residential developments built under the apartment or townhouse building types defined in the Unified Development Ordinance. Sidewalks are required on both sides of the street in a public easement. In these sections, the parking is not in the right of way, and the use of permeable pavement can be used in on-street parking areas. Multifamily Streets also are conducive to use of GSI practices including curbside bioretention, bioretention in bulb-outs and/or curb extensions, and permeable pavement sidewalks. This type is intended primarily for use in situations on roads directly adjacent to the Streetscape. The existing context may include any land use, but is often characterized by architecture such as strip malls, internally oriented subdivisions serving > 350 dwelling units with a middle turn lane, or detached development with large setbacks. In recognition of the fact that this type of facility often plays a significant role in local multimodal mobility, the cross-section provides distinct general travel and bicycle lanes. Sidewalks are required on both sides of the street. Where the travel lanes are divided by a median, the use of GSI practices are encouraged for stormwater management; bioretention is encouraged in depressed medians and permeable pavement is encouraged in raised medians.
