TRN-1.09 - Design Standards for Public Streets

Administrative Rules Adopted by Bureaus Pursuant to Rule Making Authority (ARB)
Policy category
Policy number

I. Discussion

Public street design is based on a number of national and local engineering standards. 

The booklet, PBOT Development Review Manual to Creating Public Streets and Connections is a compilation of potentially applicable street design standards and requirements. Where possible, information has been simplified for easier understanding, and it is presented based on zoning designations.

II. Design Standards for Public Streets

Public streets shall be designed using the standards provided in the booklet,

Any appeals of Public Works Permits shall follow City Code Chapter 17.06.

III. Connectivity

When required by PBOT, development must create short blocks, streets, and, where streets are not feasible, pedestrian/bicycle accessways. They should connect to transit routes, schools, and parks, and they should connect residential neighborhoods and other activity centers to each other. 

Spacing standards are a maximum of 530 feet for streets and 330 feet for pedestrian/bicycle accessways.  A new street extension or pedestrian/bicycle accessway may be required as a condition of approval as part of a land use review.

When a land use review is not required for a development, such connections may still be required. In these cases, applicants are encouraged to contact PBOT to determine whether such connection requirements are likely to be imposed. This is especially true for projects that are located on multi-dwelling or mixed-use sites or single-dwelling-zoned sites over 10,000 square feet, that are located in a master street plan area, or that are proposing more than four dwelling units.

Connectivity requirements derive from City Code Chapter 17.88, Street Access.
