Ordinance No. 2306 <br />Page 16 of 35 <br />Page 16 of 35 <br /> <br />48. ROADWAY DESIGN STANDARDS: All roads constructed or improved by the project <br />developer shall conform to the design standards contained in Pleasanton Municipal <br />Code Chapter 19.36. For standards not explicitly described in the Code, the following <br />State of California Department of Transportation (Caltrans) standards shall be followed: <br />Highway Design Manual, and the California Manual on Uniform Traffic Control Devices <br />(CA MUTCD), latest editions. The City also references design standards from “A Policy <br />on Geometric Design of Highways and Streets” (latest edition) as published by the <br />American Association of State Highway and Transportation Officials (AASHTO). Any <br />deviations from standards must be approved by the City Engineer. (Address <br />this condition prior to plan approval) <br /> <br />49. HOT-MIX ASPHALT PAVEMENT DESIGN STANDARDS: Public roadways and parking <br />lots shall be surfaced with hot-mix asphalt (HMA) as designed according to Chapter 630 <br />“Flexible Pavement” of the Caltrans Highway Design Manual, unless otherwise <br />approved by the City Engineer. The following minimum standards shall apply to the <br />design: <br /> <br />a. Minimum design life = 20-years <br /> <br />b. R-value of the underlying soil shall be R = 5 minimum. A higher R-value will be <br />allowed only through analytic testing by a licensed geotechnical engineer or <br />engineering geologist. <br /> <br />c. Asphalt Binder classification shall be PG 64-10. <br /> <br />d. Minimum Traffic Index (TI) shall be as follows. A lower TI will be considered only <br />when justified by analytic calculations performed by a licensed civil or traffic <br />engineer according to the Caltrans Highway Design Manual Chapter 613. <br />i. Public parking lot: TImin = 4.5 <br />ii. Local Street: TImin = 5.0 <br />iii. Residential collector street: TImin = 6.0 <br />iv. Collector street: TImin = 7.0 <br />v. Arterial street: TImin = 9.0 <br /> <br />e. Minimum thickness of HMA layer = 3 inches <br /> <br />f. Minimum thickness of total structural section = 8 inches (regardless of R-value). <br />(Address this condition prior to plan approval). <br /> <br />50. HYDROLOGIC AND HYDRAULIC CALCULATIONS: The City’s storm drainage network <br />has been designed in accordance with the Alameda County Hydrology and Hydraulics <br />Manual published by the Alameda County Flood Control & Water Conservation District. <br />Said manual is available for download at: https://acfloodcontrol.org/the-work-we-do/the- <br />work-we-do-hydrology-manual/. <br /> <br />Page 39 of 617
