• Providing protected intersections and crossing treatments for bicycles and pedestrians at existing signalized intersections; • Upgrading and reconstructing ADA curb ramps and driveways; • Spot repairs and replacements for existing storm, sewer and water laterals;and • Permanent stormwater treatment facilities for areas receiving full reconstruction. Traffic signal modification design will focus on relocating pedestrian push buttons, push button posts, bicycle and vehicle detection zones, and traffic signal head placement for the new and upgraded protected intersections. Conducting traffic studies and analysis for reductions in the number of travel lanes and intersection land configurations is not included in this Scope of Services. Task 3.1 Prepare Basis of Design Memorandum Mark Thomas will prepare and submit a draft Basis of Design Technical Memorandum prior to commencing conceptual design plans identifying assumptions,codes, policies, and criteria that will be utilized to conform with the design intent identified in the Bike and Pedestrian Maser Plan and the W. Las Positas Boulevard Feasibility Study.The City will facilitate the review of the Basis of Design Technical Memorandum with stakeholders. Supplemental design basis memorandums,as identified in the tasks below,will be added to the overall Basis of Design Technical Memorandum as appendices. Task 3.2 Civil Design Basis Memorandum Mark Thomas will prepare a civil design basis memorandum summarizing assumptions, design concepts,guideline criteria,and codes and regulations applied to the complete roadway design of the Project corridor and how they were applied in considering the objective of the W. Las Positas Boulevard Feasibility Study.The topics addressed will include, but are not limited,to assumptions considering safety and comfort of all roadway users,curb alignments,crosswalks, ADA requirements,traffic lane alignments, bike lanes, and stormwater treatment options and locations. Task 3.3 Landscape Design Basis Memorandum Mark Thomas will prepare a landscape design basis memorandum summarizing assumptions, design concepts, guidelines, criteria, and codes and regulations applied to the complete landscape design on the Project corridor including preservation of existing trees and plant material, new plantings, landscape design approach for stormwater treatment facilities to address C.3 requirements,and irrigation design approach.The memorandum will include a written narrative/description of proposed improvements Task 3.4 Develop Preliminary Corridor Plans and Estimates Mark Thomas will prepare one (1) set of preliminary corridor plans for W. Las Positas Boulevard showing two alternative treatments.Alternative 1 will include interim condition with striping and plastic delineator posts used to construct the Class IV cycletracks and reduced pavement reconstruction options.Alternative 2 will include the ultimate project improvements with landscape buffer medians and protected intersection treatments.The project will be broken down in the following seven segments: 1) Foothill to Muirwood(Including intersection improvements) 2) Muirwood to Payne (Caltrans) 3) Payne to Hopyard 4) Hopyard (including intersections of Hopyard,Willow)to Hacienda 5) Hacienda (Including intersections of Hacienda and Stoneridge)to Stoneridge 6) Stoneridge to Owens(including intersection of Owens) 7) Owens to Fairlands including intersection of Santa Rita The Corridor Plans will include up to six(6) intersection detail exhibits to investigate potential protected intersection configurations at Hopyard Road,Willow Road, Hacienda Drive,Stoneridge Drive,Owens Drive,and Santa Rita Road. Proposed bicycle facility improvements and crosswalk enhancements will be shown to identify the proposed design elements and potential impacts.The design concepts will include preparation of a corridor-level plan drawing on aerial photo with intersection details,and typical sections for use in presenting the proposed improvements to stakeholders and the public.The design detail will be sufficient to prepare a Caltrans 11-page planning type cost estimates for each alternative and identify risks, construction phasing alternatives, and additional investigations needed to verify assumptions. Fehr&Peers will provide concept-level cost estimates for traffic signal, lighting, and electrical improvements to be included in the 11-page cost estimate.Toole will conduct a peer review of the concept plans for adherence to bicycle and pedestrian facility design guidelines and standards.
