In 1987, the crestwood Local School District residents approved a 3.5- mill permanent improvement levy. Proceeds from this levy can be used to purchase or repair those items in the school district that have a long term useful life. Typically a five (5) year useful life or more is utilized when determining the use of these funds. The money from a permanent improvement levy can be used to purchase school busses, school building equipment such as boilers, furnaces, hot water heaters, water fountains, light fixtures, technology, athletic equipment and band equipment, etc. It can be used to replace or repair school roofs, cracked sidewalks, windows, as well as for the purchase of new textbooks, desks and instructional equipment.
