Changes to the contract prompted by: 1)Unanticipated utility conflict-An existing waterline across creek had to be lowered because it
was in conflict with proposed grading on the creek banks.The water line was shown in the construction plans in plan view however a profile of it
was not shown and SUE level A did not find it within 12 feet of depth where probed; 2)To protect against erosion,a 4"concrete flume
was constructed along edge of north retaining wall at downstream end of project-The June 24,2014 heavy rains caused severe erosion and
damage along the top edge of the recently installed concrete block wall.A concrete flume was recommended to channel offsite runoff away from
the wall. 3)One row of sheet piles was not required because one of the 3 proposed drop structures was eliminated due t ion
change at the outfall being 2 feet less than that shown in the plans. 4)A significant amount of the proposed Articulat cqR
M the bottom of the channel was not used because it was found during construction that the existing concrete rip-rap in t s
C-1) approximately 12-18"thick. It was decided to keep the bottom concrete rip rap.
