APPROACH t&I BKF 100+ YEARS ENGINEERS.SURVEYORS.PLANNERS (1) Documentation of Existing Conditions, (2) Verification of Compliance/Deviation with Applicable Accessibility Design Standards, (3) Identification of Feasible Remediation Strategies and Solutions and Costs for Improved Pedestrian and Bicycle Circulation and Upgrades to Meet ADA Compliance (4) Final Determination/Implementation of Design Concepts BKF has implemented this 4-step process on several similar and regional projects in the greater San Francisco Bay Area and have worked hand in hand with the Caltrans on challenging interchange improvements for the disabled and non- motorized public. As part of our approach, BKF recognizes that an organized project delivery approach is critical for a projects success. A well-executed project results from effective project management and communication to understand the needs of the client, direct the flow of information, define and track tasks, assign the appropriate personnel to complete the work, and ensure a technically sound, cost-effective data set presented in an easily readable format. For additional details on the scope (commensurate of our understanding and approach), see our Work Scope Summary below: Key/Relevant Project Issues Summary • Standards Through BKF's experience, differing (and sometimes conflicting) standards, requirements and guidelines are occasionally referenced in the different local, County, State and Federal guidelines (ADAS, CBC Title 24, PROWAG, County and Caltrans). An example is Caltrans' current (2015) standard plans (based on their Highway Design Manual and DIB 82-05, Pedestrian Accessibility Guidelines for Highway Projects)which require much more conservative 7.5% max curb ramp slopes, 1.5% max sidewalk/ramp cross slopes, 4'-2" min ramp widths, and 9% max curb ramp wings; these values exceed federal accessibility standards/requirements, and were revised by Caltrans primarily for the purpose of design and construction tolerance and insured ADA compliance. The actual federal requirements are still 8.3%, 2%, 4', and 10%, respectively, but provided the work is outside of the State Highway System (Caltrans R/W), using the federal standards/requirements is still acceptable and in compliance. Additionally, Caltrans has not permitted the use of bicycle or pedestrian designs that are not on FHWA's approved list unless it is used as an experimental project approved by FHWA. Some of the suggested NACTO designs are not currently on FHWA's approved list so this will need to be reviewed carefully. • Laser Level/Inclinometer Calibration Field recognizance can primarily be performed with field visits for the verification of existing pedestrian and bicycle facilities but identifying compliance with ADA standards may need to be assessed with surveys. BKF will use our Leica High Definition C10 Laser Scanner to conduct the survey and will calibrate our laser levels and inclinometers (using our survey equipment to rectify)to insure our initial visual field measurement protocol efforts are accurate to verify whether existing condition accessibility standards are (or are not) in compliance. • Outreach and Coordination The proposed solutions and improvements are only effective if there is consensus. For the work within the interchanges, it is important to ensure that • City staff is comfortable with the proposed alternatives • the work is presented to Bicycle Pedestrian Trails Committee(BPTC)for suggestions and endorsement • the plan is reviewed with Caltrans for confirmation that proposed elements would be acceptable and any design exceptions are reasonable • a final presentation outlining the elements that resulted for the above efforts is validated by the City and BPTC City Of Pleasanton I I-580 and 1-680 Bicycle and Pedestrian Overcrossing Improvement, ['LEASANTCN�I.
