Railroad Quiet Zones
In response to concerns expressed by community members regarding the impacts of train horn noise, city staff is planning several “quiet zones” for railroad crossings impacting Boulder.
Quiet zones are railroad crossings that include physical infrastructure and warning systems so that train engineers are not required to sound the train horn at the crossing. The city has been awarded a $1.2 million in grant funding from the Denver Regional Council of Governments to advance quiet zones for the Boulder community. This grant is expected to fund the construction of the Pearl Parkway and 47th Street crossings and design the 55th Street (north of Arapahoe) and 63rd Street (north of Arapahoe) crossings.

2017: $1.2 million in grant funding was received from the Denver Regional Council of Governments for Quiet Zones design and construction
February 2018: Preliminary design of crossing at Pearl Parkway, 47th Street, 55th Street (north of Arapahoe) and 63rd Street (north of Arapahoe)
Spring - Fall 2018: Final design, review and approvals
Late 2018/Early 2019: Construction of improvements at Pearl Parkway and 47th Street crossings
Construction of the 55th and 63rd Street crossings (north of Arapahoe) may also be possible though the $1.2 million grant. The Valmont Road quiet zone improvements are being constructed through a separate transportation capital improvement project.
The city will continue to pursue other funding opportunities for any remaining locations in conjunction with Boulder County and adjacent municipalities.

The community provided input on a number of factors, including the number of people living and working within 0.5 miles of the railroad crossings, type and proximity of adjacent land uses (existing and /or planned), as well as street characteristics, safety, and costs for installation, plus any potential on-going maintenance responsibilities.
These were conducted by the City of Boulder in partnership with Boulder County and the Federal Railroad Administration. To view the previous two open house presentation materials and boards, please see the links below.
