A Public Hearing will be held tonight in Ridgefield.  Residents can comment on whether the Aquifer Protection Agency should be under the jurisdiction of the Planning and Zoning Commission, or the soon to be elected Inland & Wetland Board.  A Charter revision approved last year separated the Board from the Commission.  The oversight question for the APA came up because of language in the ordinance creating it, which says obligations are assigned to members of the Planning and Zoning Commission in their capacity as the Inland Wetlands Board.  Tonight's hearing is at 7:30 in the Veterans Park Elementary School Auditorium.  The Board of Selectmen will eventually a recommendation to send to voters at a town meeting, likely in September.
