INTRODUCTION

This report contains a summary of public involvement efforts associated with the second US 6 - Clifton Access Management Plan Open House. The purpose of the open house was to present the preliminary access management plan recommendations developed by the study team. Members of the project team, including representatives from the Colorado Department of Transportation, Mesa County, and PBS&J, were on hand to address the public’s questions and concerns. The open house format allowed people to come and go at their convenience and provided opportunities for people to speak with project team members one-on-one. Assistance for people with disabilities was offered upon request. Project information was presented through a combination of display boards, roll plots, brochures, and a DVD video. Attendees began the open house by registering at a sign-in table, where a staff member collected their contact information. Display boards were placed around the room, covering various aspects of the study. Two large study area maps displaying the proposed access modifications were on display in the center of the room. Attendees were able to use Post-it notes to provide comments on both the boards and the map. A video presentation providing an overview of access management was played throughout the evening. Tables were available for attendees to sit and complete their comment forms and enjoy refreshments. The meeting date, time, and location were as follows: Date: July 16, 2008 Time: 5-8 p.m. Location: Clifton Community Hall 126 2nd St There were 34 people in attendance. The sign-in sheets are attached to this report as Appendix A.

Category Comment The changes to US 6 and I-70 BL will make for easier and safer access. The impacts on the post office, fire department, school and numerous businesses will be enormous. The intersection of 3rd into Peach Tree should have a ¾ intersection. This would eliminate most of the accidents that have occurred and still keep access viable to the shopping center. Please consider a ¾ access or a ½ access minimum. The other access nearby is a very difficult access to maneuver and would damage business substantially. It is difficult to be a small business if there is not direct access.

Access

Southbound I-70 B traffic that wants to access US 6 should be forced to do so at 32 ½ Road instead of at the traffic signal at I-70B/FRoad.

Moving the access point for Peach Tree Center to 2nd Street will diminish the value of the vacant land near the center. It will make the F Road visibility for the two lots that front F Road have relatively little value to the developers.

Peach Tree Center access must be taken into consideration fur future planning. It must remain a retail hub. Access is always a consideration for retail space value.

Traffic Traffic turn lights on I-70 BL need to be adjusted to volume of turning vehicles. Numerous contentious issues will arise, due to the access changes. Residents will do their best to keep their interests in the forefront of the project. Environmental Justice of the local population has been neglected at the post office, where the bulk of locals obtain their mail. The local grade school has been forced by the plan to forfeit the playground to traffic and the children will have a smaller play area close to the major road.

Misc.

Good presentation.

The two “T” intersections are not conducive to efficient movement of east/west traffic on F Road. Looking to the future it is even more imperative that the flow of east/west traffic not be impeded.

NEXT STEPS The display boards and proposed access modifications map are available on the project Web site. The project team will consider questions and comments provided by the public during the open house.

What is an access management plan?Any intersection or driveway along a roadway is called an access point. The purpose of an access management plan is to determine what access points will be allowed, where they will be located, and what kinds of traffic movements will be allowed at each one.

What are the goals of an access management plan?

Provide appropriate level of access to properties adjacent to the highway

Provide for the safe and efficient flow of traffic

Right-in, Right-out

Only right turns are allowed

Traffi c median prevents left turns and

straight movements – these movements must be completed at another intersection

3/4 Movement

Right-in, right-out and left-in are allowed

Traffi c median prevents left-out and

straight movements – these movements must be completed at another intersection

Full Movement

All movements in all directions

are allowed

May require the

installation of a traffi c signal

Why Have an Access Management Plan?

Without an access management plan residents, property owners, and businesses could experience:

Greater number of crashes involving vehicles and/or pedestrians

Increased traffic congestion, resulting in higher levels of pollution and more delays

A loss of visual appeal along the roadway

A difficult driving experience due to driveway clutter

Customers doing business on a highway with a better driving experience

How is an Access Management Plan Developed and Implemented?

Conduct the study

Propose improvements based on study findings and public input

Accept the final plan

Prepare an Intergovernmental Agreement between CDOT and Mesa County

Specify how elements of the plan can be changed in the future, if necessary

Sign the Intergovernmental Agreement and adopt the plan

Present to the Colorado Transportation Commission and get approval from the CDOT Chief Engineer so the plan becomes law

Continuing coordination between CDOT and the communities in the corridor to ensure proper implementation of the plan in the future

2008 Existing Traffi c Volumes and Level of Service

Page 29: Open House #2 Summary Report · Open House #2 Summary Report Date of Meeting: July 16, 2008 Prepared by: 4601 DTC Boulevard, Suite 700 Denver, CO 80237 303-221-7275

Roadway traffic congestion is expressed in terms of level of service (LOS) as defined by the Highway Capacity Manual (HCM). The conditions defining the LOS for roadways are:

A

BB

CC

DD

EE

FF

What is LOS?

LOS A – Represents the best operating conditions and is considered free flow. Individual users are virtually unaffected by the presence of others in the traffic stream.

LOS B – Represents reasonably free-flowing conditions but with some influence by others.

LOS C – Represents a constrained constant flow below speed limits, with additional attention required by drivers to maintain safe operations. Comfort and convenience levels of the driver decline noticeably.

LOS D – Represents traffic operations approaching unstable flow with high passing demand and passing capacity near zero, characterized by drivers being severely restricted in maneuverability.

LOS E – Represents unstable flow near capacity.

LOS F – Represents the worst conditions with heavily congested flow and traffic demand exceeding capacity, characterized by stop-and-go waves, poor travel time, low comfort and convenience, and increased accident exposure.

Why Does US 6 -Clifton Need an Access Management Plan?US 6 is an important resource for the communities of Clifton, Palisade, and Grand Junction

Traffic volumes on US 6 are projected to significantly increase in the future

Current and Future Traffic Volumes

US 6 Segment Daily Traffic Volume (2008)

Daily Traffic Volume (2035) % Increase

I-70 B to 2nd Street 18,000 49,000 170%

2nd Street to 33 Road 12,500 39,000 210%

East of 33 Road 9,060 19,000 110%

2008 Daily Traffi c Volume Source: CDOT and PBS&J2035 Daily Traffi c Volume Source: Mesa County

One of the best ways to keep US 6 safe and efficient is to manage the location and design of access points

2035 Build* Traffi c Volumes and Level of Service

*Under build conditions the roadway was assumed to have two lanes in each direction with turn lanes at intersections, and access conditions were changed to match the recommended plan.

Page 34: Open House #2 Summary Report · Open House #2 Summary Report Date of Meeting: July 16, 2008 Prepared by: 4601 DTC Boulevard, Suite 700 Denver, CO 80237 303-221-7275

The recommended Access Management Plan provides several benefits to the overall operations and safety along the US 6 - Clifton corridor. The following is a summary of the potential improvements and benefits.

Improve Traffi c Flow

The number of access points is reduced.

Reduce Traffi c Confl icts

Reduction in the number of conflict points.

Median cross over points are eliminated at non-critical locations.

Improve Traffi c Safety

The potential of high-speed rear-end, broadside, and sideswipe accidents is reduced.

More vehicles enter and exit the highway by making right turns, which are safer than left turns.

Provide Adequate Access to Adjacent Land Uses

All properties have access to US 6 or the secondary street system

Better use of the secondary street system or shared access locations to prove access to adjacent land uses.

The recommended Access Management Plan meets the established goals for the project by improving traffic flow, reducing the number of conflicts, improving traffic safety, and providing adequate access to the adjacent land uses.

Benefi ts of the Recommended Access Management Plan

Page 35: Open House #2 Summary Report · Open House #2 Summary Report Date of Meeting: July 16, 2008 Prepared by: 4601 DTC Boulevard, Suite 700 Denver, CO 80237 303-221-7275

Access Management Plan is a long range vision for US 6 -Clifton

Implementation of the plan will occur in phases or incrementally over time based on:

Traffi c needs

Safety needs

Available funding

Redevelopment

There are currently no planned state or federal projects or identified funding for improvements to US 6 that would change access in the near future

Additional planning and public input are needed to support the recommendations of the Access Management Plan and to identify the ultimate design (right-of-way needs) for US 6.

The future studies will consider the appropriate improvements to US 6 that address both traffic and pedestrian needs.

The following conceptual diagram depicts one possible option for future laneage on US 6 through Clifton based on 2035 volume projections developed by Mesa County. Mesa County and CDOT will conduct future studies and public involvement to determine the exact number of lanes and right-of-way requirements to ensure US 6 meets the future needs of local residents, property owners, and business owners as well as accommodating pedestrians and future traffic volumes.

PUBLIC INVITED TO US 6 - CLIFTON ACCESS MANAGEMENT PLAN OPEN HOUSE

We’re Studying Your Access to US 6!

MESA COUNTY – The Colorado Department of Transportation (CDOT) and Mesa County are inviting residents to the open house regarding the Access Management Plan being developed for US Highway 6, from the I-70 Business Loop to the railroad viaduct just east of 33 Road. The open house will be held Wednesday, July 16 2008 at the Clifton Community Hall, located at 126 2nd Street in Clifton. People can attend anytime between 5:00 p.m. and 8:00 p.m. Representatives from CDOT, Mesa County, and their consultant, PBS&J, will be available to address questions or concerns about the plan. The study team has assessed the existing and proposed intersections and driveways (access points) on US 6, has considered public comments provided at the first open house in April 2008, and is now ready to share its recommendations for future changes. Informational boards explaining the plan’s goals and objectives, and maps identifying recommended future access points will be on display at the meeting. Additional information is available on the project Web site: http://www.dot.state.co.us/us6clifton/. Reasonable accommodations will be provided for persons with disabilities. Please call Ryan Adams at PBS&J, (800) 497-5529, if you require such assistance.
