Mr. Mike Tassano November 4, 2015 Page 2 of 3 SCOPE OF WORK FEHR''PEERS Task 1— Prefirnfnacy Engineering Using available aerial mapping, any available topographic mapping, and the preliminary interchange design concept prepared by Fehr & Peers, MTCo will develop up to two (2) geometric alternatives for vehicular roadway improvements along Stoneridge Drive and on the westbound to northbound 1 -680 on -ramp, MTCo will develop a minimal design alternative which will minimize cost and impacts and will require Cattrans approval of design exceptions, including ramp metering exceptions. MTCo will also prepare an alternative that meets all feasible design standards including ramp metering for 2 mixed flow lanes and HOV bypass, which is the current Caltrans requirement Using available data from the JEDZ transportation impact study, Fehr & Peers will estimate ramp metering queues to inform the design. As part of this task MTCo will identify the need for and feasibility of widening the bridge. Ramp modifications will be designed to avoid shifting the ramp gore -point north if possible, recognizing the potential adverse impacts such a ramp modification would have to mainline I -680 operations due to the proximity of the 1-580/I -680 interchange. MTCo will prepare geometric layouts at 1' = 50' scale on readily available open source orthorectified aerial mapping. MTCo will prepare horizontal layout and prepare typical cross sections. This scope assumes widening only and no changes to roadway or ramp profile. In addition to the vehicular roadway design alternatives. MTCo and Fehr & Peers wilt work with the City to develop up to three bicycle route alternatives (Class! and Class 11), considering guidance in the rTE publication Recommended Design Guidelines to Accommodate Pedestrians and Bicycles at Interchanges (April 2014). guidance from the City's Bicycle Master Plan (update currently underway), and our understanding of Caltrans complete streets and Highway Design Manual guidelines. MTCo will prepare preliminary construction cost estimates for each of the alternatives based upon Caltrans 6 -page format MTCo will include construction cost estimates for roadway, structural, right of way and support costs for each roadway alternative. Cost estimates for bicycle route alternatives will be prepared to identify the marginal cost of each altemative so that the selected bicycle route may be added to the selected roadway alternative to understand the likely total project budget. Deliverables • Geometric Layouts (2 alternatives) at 1'=50' scale • Bicycle Route Layouts (3 alternatives) at 1 " =50' scale • Project Budget Estimates (Caltrans 6 -page format) 1 per alternative per above
