138 ENVISION FRANKLIN | Appendix APPENDIX A: EXISTING CONDITIONS AND TRENDS Existing conditions and trends were assessed in the first phase of drafting this Plan. Information contained within this Appendix was gathered in 2022 and 2023. Figures A.1 and A.2 show the 2015 estimated population and employment density, respectively. These figures represent the number of persons per acre for population and the number of jobs per acre for employment by traffic analysis zones (TAZ). The projections for each TAZ are sourced from the Greater Nashville Regional Council (GNRC). By using TAZs to project population, the GNRC and Franklin can more accurately plan for where transportation improvements may be needed as a result of increased traffic, density, and travel times from within each TAZ. Every TAZ that intersects with the urban growth boundary (UGB) of the city was included in the population and employment projection maps to provide a better overview of the growth occurring both in and around the city. Based on these projections, the city can expect the most employment and population growth to both occur in the Cool Springs and Goose Creek areas. Although these projections provide a geographic perspective of where growth will occur, the GNRC does not provide projections for areas within the Franklin UGB as a whole, therefore the city coordinated with Williamson Inc. to calculate estimates for the 2040 employment projections. The TAZ projections from the GNRC are based on population and employment estimates from 2017, then projections are provided for every 5 years to 2045. The projection methodology of the GNRC is sourced from Woods & Poole Economics, which uses more than 900 variables to more accurately and comprehensively project population, employment, and the movement of economic activity around the country. The 2022 technical summary for the Woods & Poole Economics projections methodology can be found here: https://www.woodsandpoole.com/wp-content/uploads/2022/06/TECH22-summary.pdf Williamson County is expecting continued growth, with a focus of developing within the cities and in the County’s Planned Growth Areas. According to a Woods and Poole population projection, Williamson County’s population will be 315,000 in 2030 and 394,000 in 2040. By 2040, it is projected that 133,647 will live in the City of Franklin / Franklin UGB area. This is a 52 percent increase in population from the 2015 estimate of 87,921. Projected employment within the study area for 2040 is 126,667, a 49 percent increase from the 2015 estimate of 84,995 jobs. In addition to the existing population concentrations, additional residential development is anticipated to the northwest, between Hillsboro Road and State Route 96, around the Goose Creek interchange, in the Cool Springs area, and east of Interstate 65 along the Murfreesboro Road corridor. Figure A.4 shows the 2040 projected population density. Employment growth is primarily expected to occur in established commercial areas, specifically the Cool Springs area, along Carothers Parkway. A new employment concentration is being developed around the Goose Creek interchange. Additionally, Downtown Franklin will also continue as an employment center. The 2040 projected employment density is shown in Figure A.5.
