The proposed new fees, if approved by commissioners, would kick in Oct. 1, the start of local government's fiscal year. Orlando area residential and commercial developers have been building feverishly in nearby Lake for the past seven years, taking advantage of some of the lowest impact fees in the state.

But now those fees, if adjusted, would compare with existing fee schedules in surrounding counties, commissioners argue. They are studying proposals made by their hired consultant, Tindale, Oliver & Associates of Tampa.

Fast-food restaurant developments may take the biggest hit--up 869.1%, from $1,182 per 1,000 sf of space to $17,706. General commercial projects, such as strip retail centers of 50,000 sf to 200,000 sf could face an increase of 260.4%, from $604 per 1,000 sf of development to $2,177.
