COUNTY OF HAWAII I PL.4)COMMUNITY PLANNING(COMMUNITY/REGIONAL PLANS,GENERAL PLAN,CLIMATE ADAPTATION) recommend them for Phase II ESAs. Using data from the Temporary UHWO Park and Ride enterprise central warehouse,properties recommended for Phase We are providing design services to support the development of a II ESA were prioritized to identify those where Phase II ESA rail station near the University of Hawaii,West Oahu(UHWO) activities are more critical based on potential presence of campus to comply with city,state,and federal requirements.To contamination, magnitude of future construction work and accommodate the anticipated ridership from this station,a workers exposure,accessibility,and acquisition status. Higher temporary park and ride is planned for development to support priority properties were grouped based on their geographic this station.The park and ride project are approximately 3.5 acres locations and a group-specific Phase II ESA and site and includes an access driveway and a new road.We are characterization work plan was prepared for each of the five coordinating with stakeholders,designing to address the current groups designing innovative investigation activities that will needs of the project while planning for the future development of optimize fieldwork and create cost-efficiencies.The use of the the site,and coordinating across several design disciplines centralized database allowed maximizing use of Phase I ESA data including,structural design support for foundations,electrical for reducing work plan preparation-times. lighting and security,and civil designs and services which Jacobs assisted HART with applying for and winning an EPA included site layouts,drainage,grading,traffic signage and brownfields assessment grant that partially funded the Phase I striping, roadway design and vehicle maneuverability. and II ESA efforts. The park and ride design requirements include the following: Additional Investigation and Remedial Action at Various • Accommodate approximately 300 passenger cars Locations along the HTRP.Honolulu.Oahu. Hawaii • Include six bus stops We have performed numerous additional investigation and • Meet current ADA requirements remedial actions for various locations along the HRTP,including ■ Provide for electric car requirements petroleum-only sites,chlorinated solvents sites,and other • Minimize impacts to adjacent roads hazardous substances sites.The objectives for these investigations ■ Meet city urban development requirements and remediation projects were to investigate the nature and • Provide for lighting and security extent of contamination in the subsurface,identify and optimize ■ Driveway design soil remediation volumes,and complete remediation ahead of • New roads for access to park and ride for both passenger construction. vehicles and buses We adopted a dynamic approach involving progressive and • Acquire necessary approvals and permits for construction iterative consultations with various stakeholders,including the • Erosion control HDOH,which resulted in expedited investigation and remediation, ' Traffic control regulatory approval,and significant cost savings. This project is a temporary solution.The design provides the We assisted HART with applying for and winning an EPA flexibility to be used by the university once the station is deemed brownfields cleanup grant,which partially funded the remediation no longer necessary and the site could be turned over. of the proposed Iwilei Station. In addition,a few of these exemplary projects were selected to be presented at various national conferences. 25.FIRMS FROM SECTION C INVOLVED WITH THIS PROJECT (1)FIRM NAME (2)FIRM LOCATION(City and State) (3)ROLE a.
