Seminole FAQ
Do I need a permit to regrade my Seminole yard?
Minor landscaping usually does not, but adding fill, changing lot elevation, or altering drainage patterns typically requires a city permit and may trigger an SWFWMD Environmental Resource Permit.
My neighbor's grading is flooding my Seminole yard - what can I do?
File a complaint with Seminole code compliance. The Land Development Code prohibits redirecting drainage that harms adjacent properties, and the city can require corrective grading or engineered fixes.
St. Petersburg FAQ

Significant fill requires a permit and engineered drainage plan under Chapter 16. You may not redirect runoff onto neighbors or block swales, and floodplain fill is further restricted by Section 16.40.050.
Do I need a permit for a new driveway culvert in St. Petersburg?
Yes. Driveway and culvert work in the public right-of-way requires a separate City right-of-way permit on top of any building or grading permits.
