Or perhaps they didn't really want too many of the public to attend, other than supporters who would have been notified via other mechanisms, such as announcements made to teachers and other SRVUSD employees. I'm probably being too cynical...
The information provided in the flyer on the purposes for the bond money was fairly vague, but the district web site has the following proposed/draft project list:
Lots of big-ticket items. Many of the items seem quite necessary, such as classroom additions and a new school for the Dougherty Valley area (due to increased students, etc.), as well as some items related to seismic retrofitting, and fire and intrusion alarm systems. But there are also lots of "modernization" items.
No mention was made of additional solar projects, which are a clever way of "converting" bond money into operational savings. But perhaps these fall under some of the "standard modernization for entire campus" projects.
