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.

2021 Update: Project Pause

This project remains a high priority, particularly due to Sumac’s standing in the top ten percent of streets with the worst pavement condition in the city and its proximity to Crest View Elementary School. Read below for further details on the project pause below. 

Sumac Avenue/17th Street property owners will receive a letter with further info in Feb. 2021. 

Given the city’s budgetary shortfalls and our sensitivity to the cost burdens residents may be experiencing due to COVID-19, staff feels it prudent to pause the project until the current financial situation has stabilized. Staff will continue to incorporate feedback received from corridor residents and stakeholders into the project design. We anticipate sharing the final design plans with the community in the future.

Transportation Maintenance will continue to address pavement surface issues in the interim.

Additionally, the Utilities Division will be performing a needed waterline replacement from Broadway to 19 th Street in Spring 2021. Sumac property owners will receive further notice prior to this work beginning. Please reach out to Josh Meck [email protected] or 303-413-7439 with questions.
