Transect 1 (T1). Natural Zone consists of lands approximating or reverting to a wilderness condition, including lands unsuitable for settlement due to topography, hydrology or vegetation.

Transect 2 (T2). Rural Zone consists of sparsely settled lands in open or cultivated state. These include woodland, grasslands, parks and open space areas. Typical buildings are farmhouses, agricultural buildings or cabins.

Transect 3 (T3). Sub-Urban Zone consists of low-density residential areas, adjacent to higher density zones that include some mixed use. Home occupations and outbuildings are allowed. Planting is naturalistic and setbacks are relatively deep. Blocks may be large and the roads irregular to accommodate natural conditions.

Transect 4 (T4). General Urban Zone consists of mixed-use but primarily residential urban fabric. It may have a wide range of building types, such as single-family, sideyard buildings, and rowhouses. Setbacks and landscaping are variable. Streets with curbs and sidewalks define medium-sized blocks.

Transect 5 (T5). Urban Center Zone consists of higher density mixed-use buildings that accommodate retail, offices, rowhouses and apartments. It has a tight network of streets and small blocks, with wide sidewalks, regularly spaced street planting, and buildings set close to the sidewalks.

Transect 6 (T6). Urban Core Zone consists of the highest density and height, with the greatest variety of uses, and civic buildings of regional importance. It may have larger blocks, and streets have regularly spaced tree planting with buildings set close to the wide sidewalks. The T6 urban core is typically associated with downtown Flagstaff, thus this transect would not be applied in other locations within the City.

Utilities. Installations or facilities furnishing, for the use of the public: electricity, gas, steam, communication, water, drainage, sewage disposal, or flood control; utilities may be owned and operated by any person, firm, corporation, municipal department/division, or board, duly appointed by State or municipal regulations.
