Mayor Buol read the call and stated this is a special session of the City Council called for the
purpose of discussing the results of the Eagle Point Bluff Study performed by Kleinfelder, Inc.
City Engineer Gus Psihoyos introduced Dr. Bill Gates of Kleinfelder, Inc., who gave a
PowerPoint presentation on the results of Phase I of the Eagle Point Bluff Study. He stated that
the controlled blasting in 2003 had been conducted appropriately; however, the causes for
instability and failure of the bluff was the excavation at the base of the bluff that resulted in
oversteepening, which was exacerbated by the mechanical excavation methods used. Various
stabilization options for commercial development, residential development and for an
undeveloped bluff were discussed. These included controlled blasting, controlled blasting with
rock bolt reinforcement, rock bolt reinforcement, and wire mesh drape slope protection. The
cost of stabilization ranged from $180,000 to $350,000, depending upon the method(s) used.
He noted that removal of the trees from fifteen to twenty feet behind the brow of the bluff and the
installation of horizontal drains at the foot of the bluff would be necessary with any stabilization
option. The next phase of the study will narrow down the final design for stabilization, including
more specific cost estimates. In response to a question, Dr. Gates stated that once the bluff
was stabilized, development at the base would not cause further damage.
There being no further business, upon motion meeting adjourned at 6:47 p.m.
