The current plan for the SL Valley is from
Envision Utah and the Wasatch Front Regional Council. The plan is to build nodes around the valley.
The nodes will be where higher intensity development occurs. The nodes will be on rapid transit lines (Trax, FrontRunner, BRT).
The following are the nodes for the SL Valley:
Downtown SLC- Metropolitan Center - highest intensity
Sugarhouse SLC - Urban Center - Mild intensity
West Valley City (Valley Fair/Fairborne Station) - Urban Center - Mild intensity
Sandy (Between Trax and FrontRunner) - Urban Center - Mild intensity
Cottonwood Heights (Old Mill) - Urban Center - Mild intensity
Draper (Point of the Mountain) - Urban Center - Mild intensity
Murray - Urban Center - Mild intensity
The idea is that these nodes will be the focus for higher intensity developments. As they connect to other nodes via frequent transit, the hope is that this will reduce traffic while improving air quality.
The overall goal is to keep the higher intensity projects located in downtown SLC. The other nodes may have some taller buildings but will not be the focus of higher intensity developments. Think of the nodes as TOD's if this helps.
Overall, the plan is to have the City be a City and the suburbs be suburbs with a small area of increased intensity.
I do think though that we will some some additional areas outside of these nodes like South Salt Lakes downtown plans. But even then, it is on and around frequent transit lines.
