Sumac Avenue Study

The City of Boulder Transportation Division is beginning a study of Sumac Avenue, from Broadway to 19th Street to address various infrastructure needs, including the lack of continuous sidewalks, deteriorating pavement conditions, and the need for improved storm drainage.

Due to its direct access to Crest View Elementary School, Sumac Avenue is an important east-west local street. A number of challenges affect the condition and usability of the street: the roadway pavement has deteriorated, there are street drainage issues and a lack of continuous sidewalks.

Study Purpose

The purpose of the study is to define site constraints and identify opportunities to improve the street pavement and drainage, as well as pedestrian connectivity and mobility.


The study will begin in spring/summer 2017 and is scheduled to conclude in mid-to-late 2018.


If you have questions about this project, please contact Senior Transportation Planner Noreen Walsh at 303-441-4301.
