Sumac Avenue Study

Sumac Avenue Study

The City of Boulder Transportation Division is studying Sumac Avenue from Broadway to 19th Street to address various infrastructure needs, including continuous sidewalks, pavement rehabilitation and storm drainage improvements.

The 2019 City of Boulder  Transportation Master Plan  (TMP) and recently approved  Low-Stress Walk and Bike Network  prioritize creating walkable and bikeable routes to key destinations in Boulder. 

The city has identified this portion of Sumac for near-term project work due to its deteriorating pavement conditions and proximity to Crest View Elementary School.

Study Purpose

The Sumac Avenue Transportation Infrastructure Study will explore a variety of street designs to address the corridor needs and will include an engagement process to involve the community in understanding the range of options, assessment and recommendation of a street design. The intention of the study and future project is to improve connectivity and mobility for all using the corridor, including students, parents, teachers and staff travelling to Crest View Elementary.

The study will assess multimodal improvements, review storm drainage needs and upgrades and gather community input.


From Fall 2019 through Spring 2020, the Transportation Division will undertake a transportation infrastructure study to assess a range of street designs to address the needs identified above and select a recommended option. The first of three public open houses will occur in Fall 2019, and offer the opportunity to meet the project team, review existing traffic conditions on Sumac and gather community insights and initial infrastructure improvement preferences.
