There were 8 citizen initiatives on the April 1973 ballot.  The Neighborhood Preservation Ordinance, which passed, turned out to have the most long lasting consequences.  It saved Berkeley's older houses from being demolished for ticky-tacky apartments and other eyesores.  Bulldozers were the enemy, as this poster made clear.   The initiative organizers were Martha Nicoloff and Ken Hughes.

After nearly thirty years, even leading opponents of the Neighborhood Preservation Ordinance in 1973, such as Mayor Shirley Dean, have come to embrace some of its policies.
