Trustees of the Burlingame Elementary School District are considering a construction bond measure for an upcoming ballot. But they must be looking over their shoulders. That’s because, when the city of Burlingame tried the same thing last year, that bond package fell well short of passage due to unhappy homeowners who, in the fairly recent past, had paid top-dollar for their Peninsula mini-mansions. Those properties are assessed much higher than those purchased decades ago. A revolt of the new owners trumped the will of the majority because a two-thirds approval vote was needed. Hence the failure at the ballot box. Now, the school district may be facing much the same sort of opposition. The funding issue is no different this time around. The disparity would be identical. However, if the district goes to the citizenry in a general election (November), its bond would need to achieve only a 55 percent threshold for passage. That might be enough to get past any dissident landowners.
