DUBLIN, CITY OF I-580 FALLON ROAD/EL CHARRO

1 -580 /Fallon Road Interchange E. Possible Additional Studies and Reports (From 12/13/02 PDT Meeting) At our PDT Meeting with Caltrans on December 13, 2002, Caltrans raised the issue the possibility of processing this project through federal requirements, since this project will introduce two additional access points onto I -580 by way of the new eastbound and westbound loops. Additional federal action could be triggered since a "Modified Access Report" will need to be prepared with approval from FHWA. This additional effort anticipates environmental re- evaluation of the project, revision of traffic volume to current year, additional meetings with Caltrans and FHWA, and other miscellaneous studies and reports.
