Widespread flooding continued into early 2006 after very heavy rains through December 31st brought 3 to 4 inches in a 24 hour period. Urban flooding initiated landslides that contributed to the damage, and small streams and creeks overflowed their banks. Much of the damage was in Walnut Creek, Richmond, San Pablo, Martinez and Orinda. Included in the damages were schools, park areas and several Government Buildings.
