While the project was awarded to Meek in February 2009, the start of construction did
not occur until mid- October due to the tide valve manufacturer's inability to produce a
valve unit.that complies with the design specifications. There were also concerns over
the gate unseating head pressures. Meek performed well in constructing the
improvements as originally designed. Additional time was granted for the change order
work.

The project was determined to be exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15301 (Restoration or Rehabilitation) of the CEQA
