NEXT STEPS STUDY

The intersection of Franklin Street and Buchtel Boulevard marks the westernmost edge of the proposed two-way cycle track. A complete intersection reconstruction is required in order to match the new street design of Buchtel, while maintaining the existing 12 ft. shared use path on the north side of Buchtel. Two-stage bike boxes are installed at three legs of the intersection, providing clear stopping zones for bicyclists transitioning from the adjacent, directional bike facilities.

• Long-term focus project that connects cycle track facility to existing bike routes at Franklin.

• Lower priority because existing shared use path currently provides a bicycle connection.

• Requires coordination amongst Regional Transportation District (RTD) and City of Denver to resolve ROW issues.

NEXT STEPS STUDYSUPPORTING DOCUMENTS

TO: Chris Vogelsang, PE FROM: Chessy Brady, RTD DATE: 08/03/17 RE: Response to memo of 6/30/17 titled “Future Bicycle Connection Opportunities

near Colorado Station”

We have reviewed your memo and have assembled a summary of concerns and recommendations from across many RTD departments.

Concerns: Several departments agree that mixing pedestrians, bicyclists and buses in a small space threatens the safety of the station area. With high bus activity surrounding the plaza and parking area, the proximity of Alignments A and B to the bus bays could increase the risk of bike/pedestrian collisions and serious accidents. It is preferred that areas in close proximity to RTD transit platforms be “walk your bike” zones; this applies to all 3 alignments. The layout at US36 & McCaslin, for example, has generated complaints, particularly from an ADA perspective.

Additionally, the Planning Department is concerned that Alignments A and B would require several infrastructure changes such as relocating the bus bays and TVMs.

The Rail Operations Department has concerns about Alignment C because the path would run through the traction power substation yard. As drawn, this would present security issues and limit access to the north side of the substation.

Recommendations: Capital Programs recommends the separation of bike and pedestrian movements by keeping the multi-use trail off/out of the plaza area altogether to avoid any bike/pedestrian conflicts. Capital Programs is also curious to see how the connection through the Colorado Boulevard intersection would lay out.

Several departments recommended replacing a westbound lane with a protected two-way bike facility on the north side of Colorado Center Drive. Center-running bike lanes were also mentioned.

The Safety, Security and Asset Management Department recommends moving the bicycle path south towards Evans before turning back north to the pedestrian bridge.

Takeaways: • Alignments A and B cause the greatest number of concerns across RTD departments.

• Alignment C does not create the same level of concern but exact routing could eliminateit as an option if it infringes too much on the substation yard, disrupts bus movementson Birch, or is determined to be unsafe for pedestrians. Special care would have to betaken in running the route between the PnR and the sidewalk to avoid ped/bikecollisions. Note that in the case of Alignment C, the path could just be a bike lane for

most of the distance, not necessarily a shared use path; perhaps 10’ width is unnecessary, especially at the tightest points.

• Placing the bike lanes on the north side of Colorado Center Drive reduces concernsabout bike/ped/bus interactions but does not eliminate them because there are buses onthe north side as well.

• Sharrows or on-street bike lanes on Colorado Center Drive would be less desirable froma biker perspective, but would cause fewer issues to RTD than the other options.

Hi Chris,

You are correct that designated park land cannot be used for public roadway improvements, however, a sidewalk would most likely be an acceptable addition contingent upon Parks review. Also, Parks does maintain the current Buchtel trail.

Let me know if you have any questions!

Thanks,

Adrienne‐ we’ve reviewed the materials DPR provided and see that our concept level improvements would impact Designated Park Land at the University/Buchtel intersection. I wanted to confirm that your opinion is that Designated Park Land can’t be used for public roadway improvements. Max and I were thinking about Cheeseman Park’s situation with RTD and the traveling public using 12th Ave through the Park and just want to confirm for sure that no part of the Designated Park Land can be used. Even if we could put a concrete sidewalk in the Designated Park Land as part of the Buchtel Trail that would be something useful for us to know as it would provide a little more room for us to work with in improving the University/Buchtel intersection or peds and bikes. Maybe that would be possible as long as DPR owned and maintained the concrete path? I’m not even sure who currently maintains the Buchtel Trail. It’s in the Park boundary but is not inside the Designated Park Land boundary based on the exhibit DPR provided.

Drop me a line and let me know your thoughts. We can chat on the phone if that is easier.

Thanks.
