CDOT Advances in Resiliency - Results of the I-70 Risk and Resiliency Pilot and Next Steps for Using the Results in Day-to-Day CDOT BusinessLizzie Kemp Herrera, CDOT Region 1 Manager of Planning and PMO Oana Deselnicu, CDOT DTD, Economist Aimee Flannery, AEM, Corp., Program Manager, PhD, PE Nicole Boothman Shepard
CDOT presented last year on the early stages of the I-70 Risk and Resiliency Pilot. The Pilot began in August 2016, and builds on the work completed by CDOT in the wake of the 2013 flood event. It is a first-of-its kind approach, one meant to address vulnerabilities in Colorado’s highway infrastructure before they ever become a concern. 450 miles of I-70 from the Utah border in the west to the Kansas border in the east have been analyzed for the potential of future damage and closures from physical threats. The Pilot considers multiple significant threats—ranging from avalanche to wildfire, as well as human-made threats, such as high vehicle bridge strikes.
The Pilot is now complete. Purpose of the presentation would be to present final results and spur ideas about how the results can best be used in day-to-day CDOT practices to best inform how we manage our transportation system.
CDOT also began an effort in 2017 to develop an “Emergency Response Framework”. The Framework is built off of many of the lessons learned during the 2013 floods about how much staff, and what specific skills are needed to get an emergency response center up and running quickly with all roles and responsibilities clearly defined.
US 34 Big Thompson Canyon: Building Resiliency in a Flood Prone Canyon

US 34 winds its way through the Big Thompson Canyon, providing major access between Loveland, Lyons, and Estes Park. During the September 2013 flooding, watershed runoff combined with flows released from Lake Estes Dam, mudslides and surges from debris dam breaches to generate unprecedented flow surges that exceeded the 500-year flood event. The canyon section sustained widespread, massive damage. Major sections of roadway were washed away completely, along with access bridges and retaining walls.
For the permanent repairs, many design solutions were developed and priced and from these iterations it was recognized that a full damage-proof design solution was unattainable for the available budget. For the CM/GC team a new "Resiliency" theme emerged that helped craft the direction for building this project. The resiliency based design approach was implemented to pave way for minimum 15' passable lane when the next major storm event occurs.
Some of the resilient solutions involved shifting the roadway onto bedrock or building our own bedrock in-lieu of embankment. An innovative concept of soil-mixing was implemented for building our own bedrock. Installation of shifted revetment was also used to save costs.

CDOT's Curb Ramp Program: An Overview and Lessons LearnedRick Plenge, HDR Sara Ciasto, DEA Dianna Litvak, Mead and Hunt (Env issues Greg Jamieson, HDR ROW Manager Greg Martinez, CDOT ADA Specialist
CDOT created a statewide curb ramp program that identified potentially non-compliant ramps across the state and required each CDOT Region to implement their own programs for prioritization, design, environmental clearance, and construction of the non-ADA compliant ramps. Our presenters can talk about the program(s) as a whole (how CDOT got to this point and what CCD is doing about their non-compliance), and the panel can also discuss project examples of lessons learned (Colfax), innovative techniques (ROW), and environmental challenges (specifically historic).

PMO and APD UpdatesJane Fisher
CDOT's Program Management Office was established in 2012 in support of the RAMP program intended to spend down a -$1.5B cash balance. As of December 2017, the cash balance has essentially been spent down and CDOT is now
transitioning to managing their project portfolio such that a minimum cash balance threshold by month is maintained. This presentation will provide an update regarding the current status and next steps of various PMO related initiatives that are in process in support of the transition to cash management. These include: asset/fund management evaluation and associated recommendations for improvement, preconstruction project management training and guidance,
project management software tool selection and implementation, risk based cost estimating, and standard statewide report development and implementation.

Sustainable Transportation Funding Solution: Road Use Charging, Ballot Initiative, Legislation and Federal Infrastructure FundingRoad Usage Charging: A Sustainable Transportation Funding Solution
Tim Kirby, Manager MPO & Regional Planning Section, Colorado Department of Transportation Mike Warren, Director Road Usage Charging, WSP
Over the past several years, states have been exploring road usage charging (RUC) as an innovative approach to moresustainable transportation funding through charging motorists a per-mile charge as opposed to through gas taxes. Thispresentation will discuss the reason states are exploring RUC, the use of technology and innovation to research RUC,what other states are doing with RUC policies and pilot demonstrations, and key considerations for RUC programs. Thispresentation will also present the key findings, lessons learned, and next steps from the recently concluded ColoradoRoad Usage Charge Pilot, a statewide, 100-person demonstration to explore the technical feasibility of providing a moresustainable funding solution for Colorado's transportation network.
