The planned development traditional neighborhood zone (PD-TNZ) provisions apply only to projects located within a designated “traditional neighborhood zone.” The desired development form shall be emphasized in the traditional neighborhood zone (TNZ), and strict use or density conditions shall be of secondary consideration.

A. This chapter defines two (2) different neighborhoods of a traditional neighborhood development and anticipates that one (1) neighborhood or a combination of neighborhoods may be employed in a traditional neighborhood zone.

1. Neighborhood Edge (NE): Neighborhood edge is the less dense form of traditional neighborhood development consisting principally of detached single-family homes. NE may also include a limited number of duplexes and courtyard bungalows. Buildings are situated on larger lots with setbacks on all sides. The permitted building frontage includes porches and front yards. The streetscape consists of the regular, aligned planting of shade trees in a relatively wide planter strip between sidewalk and back of curb. All building forms must be of a scale and appearance compatible with typical single-family homes. Duplexes, courtyard bungalows, and single-family are all acceptable forms in an NE.

2. Neighborhood General (NG): Neighborhood general is a primarily residential development pattern; however, it is denser than neighborhood edge and may consist of both attached and detached residence types. Multiple-family residential and nonresidential uses are permitted but shall blend into the neighborhood by occupying buildings that are of a scale and appearance compatible with single-family detached residences. Single-family homes are situated on smaller, narrower lots with shallow setbacks. The narrow lots generally require that off-street parking be accessed from the rear by alleys. A diversity of building frontages is appropriate in NG, including front yards, porch yards, door yards, forecourts, stoops, and shopfronts. Parking lot frontages are prohibited except on one (1) street side of corner lots. The NG streetscape consists of the regular, aligned planting of shade trees in a planter strip between sidewalk and back of curb.

B. Access Design: To the extent permitted by topography, all traditional neighborhood zones shall incorporate traditional block design, which includes the following elements:

1. A regular grid street pattern, unless the city council finds at the time of TNZ approval that it is not feasible due to topographical constraints.

2. Street cross sections that promote pedestrian activity and social engagement.

3. Off-street parking placed at the rear of buildings and accessed by driveway, alley or lane. On-street parking is encouraged in all traditional neighborhood forms in order to create a buffer between car traffic and pedestrians, and to introduce traffic calming friction to thoroughfares.

4. Car-oriented and large-scale commercial and industrial uses are incompatible with any of the traditional neighborhood forms. (Ord. 2019-10-002, 10-10-2019)
