Professional On-call Engineering Services City of Santa Ana T f RPP No. 17-083 Key Issues COMPLETE STREETS The City is Implementing this project as part of its Complete Streets program. Complete streets Improve safety and accessibility for all users: pedestrians, bicyclists and motorists. Typically, a complete street can Include sidewalks, bike lanes (or wide paved shoulders), special bus lanes, comfortable and accessible public transportation stops, frequent and safe pedestrian crossing opportunities, median Islands, accessible pedestrian signals, curb extensions, narrower travel lanes, and roundabouts. During v the Preliminary Design stage, we look at alternatives to implement these features into the design. Specific areas that the APP Team will review will include the following: _ • ADA • Verify that the impacted sidewalks and curb ramps are compliant with the most -current 03 standards; • Curb Extensions — Review areas where curb extensions can be introduced that will improve pedestrian access and safety; o 11 It Bike Lanes - Review bike lane configuration to account for appropriate bike and vehicular movements, driveways, and pedestrians `I PAVEMENT REHABILITATION As illustrated in Exhibit 1; Roadway Reconstruction/Rehabilitation Cost Alternatives on the following page, optimizing the pavement rehabilitation strategy for Mile One Street can result in significant cost savings to the City. APP excels at evaluating and considering refinements to the recommendations in pavement reports to develop economical rehabilitation strategies and is an industry leader In the design and implementation of cost-effective pavement rehabilitation strategies including cold -in-place recycling, full depth recycling and maintaining the existing aggregate base in place. s` We will explore options and provide the City with the best pavement solutions to maximize Its construction budget. Depending on the application, these pavement alternatives can reduce project g: costs up to 50 percent or more over traditional paving methods. Exhibit 1 on the following page provides a relative cost comparison for traditional asphalt concrete on aggregate base pavement section (6" AC over 12" aggregate base) to four (4) other less costly paving/rehabilitation options: • Pull depth reclamation of the existing asphalt section > 3 • Reconstruction of asphalt over recompacted existing aggregate base • In-place cold recycling of existing asphalt • Cold milling and replacing with AC surface These paving options include construction cost estimates for the various materials (asphalt, base) and field operations (excavation, cold mill, compaction) as well as an allowance for miscellaneous concrete B improvements and a comparison of the costs options that we can investigate with the City and incorporate into the project documents as applicable. ENVIRONMENTAL s To implement the improvements, the City of Santa Ana will be using local and federal funds for the project. Caltrans' Division of Local Assistance will be the administering agency for the approval and 4 dispersal of the federal funds. As such, both state and federal environmental documentation will be required to satisfy CEQA and NEPA, in compliance with Caltrans' Local Assistance Program. Projects that receive federal funding through Caltrans are required to complete a Caltrans Preliminary Environmental Study (PES) form which will recommend the appropriate NEPA documentation. In our experience these types of projects would have a minimal environmental impact; therefore, it is assumed that the recommended document will be a NEPA Categorical Exclusion (CE). The CEQA Lead Agency will be the City of Santa Ana. CEQA documentation will consist of at CEQA Categorical Exemption (CE)., aI _ - ANDERSON PENNA
