2 LAND USE PLANNING AND POPULATION

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.

Figure 2-1:
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

 

Table 2-2:
Residential Density for the Performance Based Overlay District

 

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

 

2.2 FUTURE POPULATION ESTIMATES & LAND USE

Future wastewater demands were projected for buildout using the City's 2018 Land Use Map zoning designations (Figure 2-1) along with the most recent General Plan. The City of West Jordan Planning Department utilizes the estimates of residential dwelling unit densities shown above and occupancy rates (people per household). While an approximate population number can be determined from this data, the buildout scenario used in this master plan update utilizes the densities, occupancy rates, and the approved land use map to calculate future wastewater demands. Therefore, no specific population number is used within this update.
