2.1 EXISTING POPULATION ESTIMATES AND LAND USE

The City's most current GIS parcel data, aerial photographs, and 2018 Land Use Map (Figure 2-1) were used to identify residential, commercial, industrial, and light industrial areas of the City. See Appendix A for the large-scale figure.

2018 Land Use Map

The wastewater flows from these areas were then individually assigned to the wastewater model. The 2018 population estimate used information from the University of Utah Kem C. Gardner Institute for residential dwelling unit densities and occupancy rates (people per household). The current citywide residential dwelling units per acre is 1.66. The City population for 2018 from the University of Utah Kem C. Gardner Institute was 111,719.

Tables 2.1 and 2.2 provide residential density ranges that are found in the most recent City General Plan. The performance-based overlay district allows increases in density when a developer adds amenities such as extra open space, playgrounds, or upgrades to building facades.

Table 2-1:
Residential Density Ranges

 

Density Designation	Current Density Range (Dwelling Units Per Acre)
Very Low Density	Up to 2.0
Low Density	1 to 3
Medium Density	3.1 to 5.0
High Density	5.1 to 10
Very High Density	10.1 and up

Density Designation	Density Range (Dwelling Units Per Acre)
Very Low Density	Up to 2.0
Low Density	1 to 3.5
Medium Density	3.1 to 7.6
High Density	5.1 to 14.1
Mixed Use	0-25
