He has dedicated significant effort to becoming our firmwide roundabout expert through delivering similar projects, attending specific trainings and national conferences,and staying updated with the latest national roundabout guides, including National Cooperative Highway Research Program's(NCHRP) Report 1043: Guide for Roundabouts.Jon has coached and mentored his core roundabout delivery team assigned to this project through the successful delivery of multiple recent roundabout projects.The City can be confident you have the right leader and design team to develop designs that meet the most modern roundabout design, performance,and safety guidelines. We Can Hit The Ground Running - Through multiple meetings and discussions with City staff over the past year,we have been fortunate to have the time to start developing initial roundabout geometry concepts.As you will see in Figure 1 on page six, we developed a "dog bone" roundabout concept that refines the City's initial concept and meets the latest NCHRP Report 1043 guidelines.We also explored the option of a traditional "circular" roundabout and proved that the"dog bone"style will require less space,operate more efficiently, and provide greater safety benefits.The roundabout concept in Figure 1 includes our initial recommendations for addressing impacts to the Lateral 38 canal,stormwater management solutions,and potential property impacts. Upon receiving NTP,we have a 15%-30%design that is ready for review and discussion with the City to determine next steps. Approach to Public Involvement - As highlighted in the RFO,an effective public outreach plan will be critical to the success of this project.As added value to the City,we can confidently say, "been there,done that"when it comes to advising our clients with developing an appropriately-scaled public involvement plan.A roundabout of this scale with "non-traditional"geometry is certainly going to attract attention from local residents.As outlined in this response,we have plan to serve as a trusted advisor to the City to assist with engaging the community through public open house events with associated graphics,figures, roll plots, and questionnaires to successfully gain community buy-in. As your Project Manager with over 20 years of delivering roundabout projects similar this one, I am committed to delivering this exciting project for the City. Our firm will commit the key personnel identified in this proposal to your project as well. If you have any questions, please call me at 208.947.9033 or email jonathan.gellingsC consoreng.com. Our team looks forward working with the City to successfully deliver this project. Sincerely, Consor North America, Inc.

Given the City's goal of keeping the improvements within existing right-of-way,the team developed an urban compact design with an ICD of 108 ft that fits within the constrained right-of-way. Even though this is a compact design,the geometry still accommodates a WB-50 design vehicle for all turning movements and a WB-67 for the through movements along Canal Blvd.Given this is our most recent roundabout design,we had the opportunity to implement several modern pedestrian and bicycle accommodations recommended in the NCHRP Report 1043 including 10-ft wide sidewalks,Tactile Directional Indicators(TDIs), and transitional lighting to improve nighttime safety.

The previous offset intersection had a high crash rate and was over capacity during peak periods. Consor completed an intersection control evaluation to compare four options,including signals,different alignment geometries,and a roundabout to select the preferred alternative. The design was developed to facilitate construction off-line from the existing primary arterial road to allow for continuous traffic operation throughout construction while also avoiding impacts to a high-pressure gas line. On-site stormwater management was designed to comply with strict flow control and treatment standards using extended dry detention basins.A similar approach is anticipated for the Wendell Filer Martin roundabout.
