Sec. 35.1-43.9. Streets, alleys, paths, and block patterns in traditional neighborhood developments.
(a) The transportation system in traditional neighborhood developments shall be modeled on a grid street and alley pattern modified to accommodate the topography of the site and parcel shape. Cul-de-sacs should be avoided to the extent possible and shall not exceed twenty percent (20%) of the total length of streets in the TND. This latter standards applies to streets, but not alleys.
(b) Private streets and alleys, built to standards as approved by the technical review committee, are permitted in TNDs. Such private streets and alleys are permitted to serve multiple lots and uses. In other words, lots and uses are not required to have their own separate entrance on to a public street and may share a private street or alley entrance on to a public street. Private streets and alleys shall be maintained by the property owners association.
(c) All lots shall front on a public or private street or on a square. Alleys shall serve only the rear or sides of lots or uses.
(d) In the TND core area, the blocks created by the grid of streets shall have a maximum block perimeter of one thousand six hundred (1,600) feet, except in areas where the steepness of topography exceeds ten percent (10%). In the latter steep areas, the block perimeter may exceed one thousand six hundred (1,600) feet so as to reduce the number of streets constructed perpendicular to the steep slopes.
(e) In areas where multi-family residential, commercial/service, and restricted industrial uses predominate, sidewalks shall be provided on both sides of the street. In single-family detached and single-family attached residential areas, sidewalks shall be provided on at least one side of the street.
(f) Pedestrian and/or bicycle routes, lanes, or paths shall be provided to connect all uses and reduce motor vehicle use. Street design shall provide for the safety of pedestrians and bicyclists. (Ord. No. O-98-013, 2-10-98)
