Seminole FAQ
Do I need a stormwater permit to build a home addition in Seminole?
Small additions usually do not need a separate stormwater permit, but additions that increase impervious area beyond thresholds require treatment and may trigger SWFWMD Environmental Resource Permit review.

No. Discharging chlorinated pool water, pressure-wash residue, or chemicals into Seminole storm drains is an illicit discharge under NPDES MS4 rules and can trigger fines.
