What the Town of Oyster Bay requires

• The Town's site plan rules hold flood plain areas to federal minimum elevations, set a nine-foot minimum elevation for habitable space and require FEMA flood zone designations on the plans.
• The Town takes part in the National Flood Insurance Program, which lets owners in its Special Flood Hazard Areas buy flood insurance. It notes that FEMA is updating the flood maps.
