95th Street Intersections Project

News/Upcoming Meetings

Next Public Meeting TBD

Project Background

There are several reasons why Boulder County is pursuing improvements to the 95th and Valmont and 95th and Section of 95th Street in Boulder County.Isabelle intersections:

  • In 2007 voters approved a sales tax to provide funding, in part, for Roadway Reconstruction and Safety Improvements.
  • The intersections of 95th and Valmont and 95th and Isabelle were among nine locations within Boulder County that were identified for funding.
  • The accident rates at these two intersections are some of the highest in the entire Boulder County road network.
  • Over the past 10 years there have been 136 reported accidents with property damage, 18 of those resulting in personal injury.

CDOT Hazard Elimination Funds

The accident levels at 95th and Valmont and 95th and Isabelle have been high enough over the past five years that they became eligible for state funding for improvements. Here is a timeline of the process Boulder County took to acquire state funding:

  • In 2010 Boulder County staff submitted accident data to Colorado Department of Transportation (CDOT) for processing.
  • In January 2011 Boulder County submitted an application for CDOT Federal Hazard Elimination monies.
  • In March of 2012 CDOT announced that Boulder County would receive funds for the project and that these funds would become available July 2014.

    Note: The designs that can be found within this application are conceptual only and in no way represent the final design for the project. In order to receive funding Boulder County was required to have a preliminary design to know approximately how much funding to request.

Design Consultant Selection

In August 2012 Boulder County publicly released a Request for Proposal (RFP) to obtain qualifications, recent relevant project experience, and a proposed scope of work from private consulting firms.

  • Short Elliot and Hendrickson (SEH) was selected through a competitive bidding process based upon their qualifications, project approach and value.
  • The SEH proposal is available here for your viewing.

    Note: the drawings that can be found within this document are conceptual only and in no way represent the final design for the project. In fact, a conceptual drawing was not required to submit a proposal and half of the proposing consultant teams did not include one and were not penalized in their evaluation for not including one.

Public Process

As with all Boulder County projects, the 95th Intersections Project will have an extensive public involvement process.

  • The outline for this process is just now being developed.
  • Please check back to this website to learn more about how to be involved in the project.
  • Please sign up for our project email list by contacting Scott McCarey. Project emails will be sent Bcc so that email addresses can remain anonymous.

Community Meetings

November 18, 2014

After being placed on hold due to constraints placed by the September 2013 flood, an open house was held at the Pleasant View Grange to resume the project. Here's a meeting overview:
  • Meeting Minutes
  • A project update and a new timeline was presented.
  • An overview of the project at the 10% design stage, which included renderings of the design looking both north and south on 95th Street - see below
  • Feedback was collected from meeting attendees on the 10% design plans
  • Staff discuss how the project will be impacted by the Xcel Energy Pipeline Project that will run underneath 95th Street. More details can be found on the County's Planning & Land Use website. 

February 2, 2013

On Saturday, February 2, 2013 Boulder County held a community meeting at a local residence. Invitations went out to all properties that had topological survey work done on their properties. The purpose of this meeting was to:

  • Begin to engage the neighborhood/adjacent property. Future public meetings will be widely advertised and held at a public venue.
  • Discuss the traffic data that has been collected over the past 10 years. A diagram with bubble representation of the accident history was presented.
  • Show how the number of accidents as well as the accident rate (accidents per vehicle trip) are some of the highest of any location on the county road network.
  • Present a map of the project area.

Boulder County took minutes from this meeting.

February 23, 2013

On Saturday, February 23, 2013 Boulder County held a second community meeting at the Pleasant View Grange. Boulder County took minutes at the meeting. Two reports were referenced during the meeting that present the benefits of adding turn lanes to rural unsignalized intersections. The FHWA study and the NCHRP study show a reduction in traffic accidents in the order of 30 percent-50 percent after left turn lanes were installed.

March 30, 2013

On Saturday, March 30, 2013 Boulder County held the third community meeting at the Pleasant View Grange.

  • Minutes to that meeting were taken and are provided.
  • Staff presented the concept of a curb and gutter treatment and how this treatment can reduce right of way needs.
  • Staff presented photos of areas in the county that currently have curb and gutter treatments.
  • Meeting attendees participated in an exercise to mark on maps where they felt the flashing speed signs should be located. View these maps.
  • Staff presented a diagram that showing how adding turn lanes can improve conditions, even if during some periods of the day the new turn lanes still don't provide enough capacity.
