The Brookfield Board of Ed has adopted a proposed budget for the coming fiscal year. The $48.5 million plan is a 3.61 percent increase over the current year. The proposed budget includes changes due to inflation, health benefits, transportation, contracts, and a legally required elementary school bilingual teacher. Oil and heat costs are expected to rise nearly 50 percent from the last fiscal year while maintenance supply costs increased by 131 percent. The budget plan must be submitted to the First Selectman by next Monday.
