GRAND/Hope to Monterey
Grand Avenue is identified in the 2005-2007 Financial Plan Appendix B, page 80 under 2008-
2009 projects; however main line breaks that occurred within the last year have necessitated the
need to move the project forward. Grand Avenue is also identified in the 2007-2009 Financial
Plan Appendix B, year, one schedule for slurry seal. By moving the project forward it will be
completed before the slurry seal project scheduled to begin July 2008.
This project will be completed in phases in order to take best advantage of when Old Mission
Grammar School, Mission College Preparatory, Manzanita School and Cal Poly are out for
Thanksgiving and Christmas vacations as well as to alleviate disruption to surrounding homes,
