    City's Plan
    The City approved a Water Supply Plan in 1998.  That Plan has since been changed.  In February 2001, the City's engineers, Brown and Caldwell, presented a revision of the City's Plan during a City Council work session.  Following is one of the documents provided during that meeting.  If you wish to see the 1998 Water Supply Plan or more of the Brown and Caldwell documents, contact City Hall.

    Reasons for Changing 1998 Water Facility Plan
     

    • Heceta Water District water production will be reduced to 1 mgd, thus water supply to City of Florence from Heceta will reduce to zero by the summer of 2002.
    • 1998 Facility Plan assumed service to full urban growth boundary.
    • Development of the 2.5 mgd surface water treatment plant on Clear Lake is no longer a feasible option.
