Street & Intersection Typologies Design Guide

***The third and final round of public input will open Summer 2021. Until then, comments and questions may be submitted to Tom Millar (, 801-535-6134).***

What is it?

The Guide will help the City create streets that are designed better for everyone.

The project creates new definitions and designs for 15 distinct kinds (or typologies) of streets in the city. These will supersede the traditional “arterial”, “collector”, and “local” street classifications. The project also assigns one of these new typologies to each of the nearly 8,400 public street segments in Salt Lake City.

The typologies consider land use context as well as citywide and neighborhood goals, allocate appropriate space for each of the five most important and competing functions of the public right-of-way (see below), and prioritize people. Without being prescriptive, the Typologies Guide is like zoning for streets, making sure we have the right streets in the right places.

Frequently Asked Questions

Because this is a reference manual only, there is no cost, budget, or construction schedule associated with adopting the Typologies Design Guide. The Guide does not lay out a plan for when a street should be redone. It is not a required or prescriptive approach for every street. It is simply a book of ideas, or a reference manual.

Every street is different and needs different things. As with current and past street projects, project planners, engineers, and decisionmakers will collect additional input and data before a street is reconstructed and/or redesigned.

The answers to many questions received during the June-August 2020 public input period are included below (click the orange link to view full size).

Why are the typologies important, and why now?

“Streets comprise more than 80% of public spaces in cities, but they often fail to provide their surrounding communities with a space where people can safely walk, bicycle, drive, take transit, and socialize.” – National Association of City Transportation Officials (NACTO) Urban Street Design Guide, 2013.

The Typologies Guide is a unique opportunity to reimagine our streets and ensure that they work better for everyone – by design. New transportation funding at the local, county, and state level provide unique opportunities to apply the recommendations from the Typologies Guide and build the kinds of streets people in Salt Lake City want (for supporting survey results, see the documents at the end of this page).

Additional comments and questions may still be submitted to Tom Millar (, 801-535-6134). (Note that the City is currently making changes to these proposed designs according to public input.

How has past input been incorporated?

From June to August 2020, the public told City planners and decisionmakers what they thought of the fifteen typologies, their designs, and their assignments on streets in Salt Lake City. The City is currently making changes to these proposals according to public input. The new drafts, with public comments incorporated, will be made available during the third and final round of input in Summer 2021.

From August to October 2019, nearly 1,200 people took an online survey and ranked the importance of these essential functions of the right-of-way, depending on common locations in day-to-day life. Their time, effort, and responses guided the development of the cross sections and priorities of the Typologies project.

Person mobility, the movement of people walking, using mobility devices, and bicycling, is the most important function of the public right of way. This is true overall, in every place type, and in responses from every cross section of survey respondents, too, including people who drive regularly but never or rarely walk or ride a bicycle. More results and the Graphic Summary Report PDF are below.
