The board of adjustment has important duties. Its functions, partly administrative and partly judicial, are defined and limited by state enabling legislation and by provisions of the local zoning ordinance. This quasi-judicial body's powers include hearing and deciding appeals, map interpretations and granting variances from the zoning ordinance. Under Nebraska Statutes, the zoning board of adjustment is not a policymaking body, nor is it intended to be. The board of adjustment is the body that provides flexibility in the administration of the zoning regulation.
