Sumac Avenue Study

Sumac Avenue Study


About the Project

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


The 2019 City of Boulder Transportation Master Plan (TMP) and 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 Avenue for work due to its deteriorating pavement conditions and proximity to Crest View Elementary School.

Study Purpose

The Sumac Avenue Transportation Infrastructure Study will assess multimodal improvements, pavement and drainage conditions and gather community input on street design options. 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.

Engagement Schedule

From Fall 2019 through the end of 2020, the Transportation Division will host three community meetings. 

Past Meetings

Open House #1 occurred on Nov 21, 2019, and offered the opportunity to meet the project team, review existing traffic conditions on Sumac and gather community insights and initial infrastructure improvement preferences. View meeting materials, including:

Open House #2 occurred on Feb 19, 2020, and offered the community a chance to review initial conceptual designs and express their preferences regarding the installation of drainage features, sidewalks and parking lanes along the corridor. View meeting materials, including:

​Open House #3 will be held later in 2020, once COVID-19 gathering restrictions are lifted for city events. Watch this page for updates. Feel free to contact project staff in the meantime with questions. Sumac Avenue/17th Street property owners interested in a one-on-one meeting with staff can request a phone call during this period.
