Permission from the Florida Department of Education to demolish and then rebuild school facilities is a three step process - (1) a Spot Survey for permission to renovate or replace; (2) a Castaldi application; and (3) a final Spot Survey for permission to demolish and rebuild. For the Bay Haven project, which entails demolishing buildings 2, 3, and 4 replacing them with a two-story structure, the first step was accomplished as part of the 2011 Five Year Plant Survey. The Castaldi step now involves preparation of a packet proving that it is more economical to rebuild than to renovate.
