ON THE SPECIFIC SITUATIONS. WHEN THE 100 YEAR
FLOODPLAIN LIMIT IS SHOWN ON THE PLAN VIEW SHEETS, IT
WILL BE USED TO SET THE MINIMUM FINISH FLOOR AND BE
RECORDED ON THE PLAT. YOU MAY AVOID THIS COMPLICATION
BY SHOWING THAT THE 100-YEAR FLOODPLAIN LIMITS ARE
ENCLOSED WITHIN GREENWAY EASEMENT, WETLANDS, OR RPA IN
DOCUMENTATIONS SEPARATE FROM THE PLAN, OR ON CROSS
SECTIONS WITHIN THE PLAN. FURTHER DISCUSSION WILL
BE HELPFUL.
