(a) Land use.
(1) The entire land area of the TND shall be divided into blocks, streets, and lots, and optional edge areas.
(2) Permitted Uses. All uses permitted in low density residential, medium density residential, community facilities, downtown and office/institutional districts are permitted within the TND.
(3) Similar land uses (uses within the same land use category) shall generally face across streets. Dissimilar uses, when adjacent, shall abut at rear lot lines. Parks and Squares Uses and Civic Uses are considered similar land uses for the purposes of this provision.
(4) Neighborhoods shall be limited in size or shape to allow residents to walk to the neighborhood square and/or commercial areas.
(5) The TND shall contain a clubhouse or neighborhood square. The neighborhood square can be used to meet the open space requirements of the TND.
(6) A neighborhood proper shall provide areas of mixed use (residential and commercial) buildings and shall encourage by design the clustering of living, working, recreation, shopping, and civic uses.
(7) A drive-through is allowed under the following conditions:
A. No more than one drive-through lane is allowed within the neighborhood proper.
B. The drive-through must not have its entrance or exit drive onto an arterial street or major thoroughfare.
C. The drive-through is located at the rear or side of the building .

(3) Pedestrian pathways shall be not less than four (4) feet in width.
(4) Utilities shall run underground or along an alley to the rear of a lot.
(5) Street lighting shall be provided along all streets. The general rule for lighting in a TND is to prefer more, smaller lights as opposed to fewer, high-intensity lights, to provide a more human scale. Street light structures shall not exceed 18 feet in height. Streetlights shall be installed on both sides of streets at intervals no longer than 75 feet measured parallel to the street. Building, wall, and freestanding exterior lighting fixtures shall be directed downward in order to reduce glare onto adjacent properties and streets. If the provisions for lighting of this TND District conflict with the municipal lighting policy, the provisions of the TND District shall prevail.
(6) The TND plan shall designate publicly and privately owned civic lots and, where possible, the general location of a civic building at the terminus of street vistas for all major internal streets. Termination of street vistas with a prominent public monument, specifically designed building facade, or a gateway to the ensuing space, is also encouraged.
(7) A neighborhood’s residences, shopping, employment, and recreation shall be connected by sidewalks, pedestrian paths, bicycle paths, and local streets.
(8) All streets shall have a six-inch high curb except for streets in House Use areas, where they are encouraged but not required. A curb, six inches in height, is required at all street intersections. There shall be curb cuts providing handicap access at all intersections and points of pedestrian crossing. Curb interruptions are permitted only for alleys, handicap access, and parking access points specified herein.
(9) Shopfront Use lots, Rowhouse Use lots, House Use lots, and Workplace Use lots shall have their rear lot lines coinciding with an alley. Alleys shall be designed in such a manner as to ensure compatibility with its intended use.

(c) Lots and buildings.
(1) Consistent build-to lines shall be established along all streets and public space frontages.

A minimum percentage build-out at the build-to line shall be established on the plan along all streets and public square frontages.
(2) All buildings shall have their main entrance opening to a street or square (except outbuildings).
(3) Stoops, colonnades, chimneys, arcades, awnings, cafes, projecting signs and front porches may encroach up to 10 feet into the front setback, as long as sufficient space for the required sidewalk width is retained.
