The Contra Costa County Board of Supervisors RESOLVES THAT:
It has been brought to the Board's attention that during periods of high tides and/or
high flow in the waterways. of Contra Costa County's Delta the wind, wave (including
passing boat wakes) and tidal action cause damage to the levees, thereby endangering the
safety of persons and property by resulting levee failure and island flooding. The
Sheriff-Coroner indicates a study by the. State of Californi 'a Department of Boating
a nd Waterways concludes a significant levee erosion is caused by the wake of a passing
boat.
Contra Costa County Ordinance Code SS410-4.001 and 410-4.004 provide that the Board
of Supervisors by resolution may designate slow areas which are speed zones in which
no vessel may be operated at a speed in excess of five nautical miles per hour.
Pursuant to Ord. C. S410-4.004 during the following listed time periods the herein-
after designated Delta waterway areas are slow areas:
1. Time Periods

Pursuant to Harbors and Navigation Code S660(c) this is an emergency regulation effective

which do not exceed 60 days from its adoption. It is necessary that this regulation be
immediately effective in order to insure the safety of persons and property during the
above specified periods of Delta high tides and high flow by preventing wakes from boats
traveling in excess of five nautical miles per hour which can breach weak levees, cause
island flooding, increase the erosion of levee crowns (and the possibility of damage to
marina property and farm lands) , and damage wildlife habitat areas.
