Belleair Beach board reviews 65% impervious-surface limit and hears case for easing rules in parts of town
Summary
Planning staff told the board that the city's impervious surface ratio (ISR) is 65%; members discussed grandfathered development, whether parts of town could be allowed a higher ISR (70%), and whether zoning or an overlay district would be preferable to one citywide change.

Planning staff opened the meeting with data showing Belleair Beach’s impervious surface ratio (ISR) set at 65%. Staff said, “we are at the 65 ratio. So that means 65% of your lot … can be impervious,” and explained the ISR is checked when building permits are reviewed.
Board members pressed on how older homes that predate current reviews were allowed different outcomes and whether raising the ISR to 70% would ease new construction that commonly includes pools and circular drives. Staff and members discussed two approaches: change the citywide ISR or allow different limits by residential category or create an overlay district for specified areas. Staff warned that overlay districts add regulatory complexity and recommended considering changes by zoning district rather than parcel-by-parcel exceptions.
Members also reviewed legal grandfathering: staff said Florida law generally preserves uses or features that were lawful when installed, but illegal work is not grandfathered. The board asked staff to verify the historical basis for the 65% figure and return with specifics and draft language if a change is recommended. The board did not adopt any ISR change at the meeting; the item remains for future consideration.
