Railroad Quiet Zones
In response to concerns expressed by community members regarding the impacts of train horn noise, the city is designing and implementing several railroad crossing Quiet Zones. These efforts are in coordination with Boulder County and other local transportation agencies to improve the safety and quality of life for the Boulder community.
Anticipated Timelines for Establishing Quiet Zones
The City of Boulder's plans to establish Quiet Zones at 47th Street, Valmont Road, Pearl Parkway, 55th Street (north of Arapahoe Avenue) and 63rd Street (north of Arapahoe Avenue) are underway.

What Are Quiet Zones?
Quiet Zones are railroad crossings that include physical infrastructure and warning systems so train engineers are not required to sound the train horn at the crossing. Quiet Zones may involve roadway improvements (City of Boulder), railroad improvements (BNSF Railroad), or a combination of both.
- Roadway improvements include safety measures such as traffic control devices, median extensions and signage that enables a crossing to become Quiet Zone-eligible (if no further railroad improvements are required).
- Railroad improvements include circuitry improvements, signal upgrades and installation of exit crossing gate arms, and can only be implemented by BNSF, owner of the right-of-way at railroad crossings.
Once the improvements are made and approved by the FRA (Federal Railroad Administration) and the Colorado PUC (Public Utilities Commission), the location is recognized as a Quiet Zone. The time frame for Quiet Zone creation varies depending on the type and extent of improvements required.
Once the locations are established as Quiet Zones, train engineers are no longer required to sound the train horn at the crossing, so residents, businesses and visitors in the surrounding areas should expect less train horn noise. Please note, the train engineer still has the authority to sound the horn if an unsafe condition exists.
Funding for Quiet Zones
Funding to design and construct Quiet Zones comes from a $1 million grant from the Denver Regional Council of Governments (DRCOG) with a local match of $200,000 from the city transportation fund.
The city will continue to pursue funding opportunities in conjunction with Boulder County and adjacent municipalities.

Background on the Quiet Zone Project Prioritization
In collaboration with Boulder County and the Federal Railroad Administration over the past five years, the city conducted a public engagement process with the community to inform a prioritization and phasing plan for implementation. Projects will be prioritized as follows:
- 47th Street
- Valmont Road
- Pearl Parkway
- 63rd Street at the Diagonal Highway (joint effort with Boulder County)
- 55th Street north of Arapahoe
- 63rd Street north of Arapahoe
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), street characteristics, safety, installation cost and potential ongoing maintenance responsibilities.
Since the original project prioritization, the city has approached Quiet Zone implementation in a holistic manner to complete projects in as quickly possible.
