Largo regulates site grading and drainage through CDC Chapter 11 stormwater rules and Chapter 8 general design standards, requiring runoff to be managed on site without harming neighbors or the public storm system.
Site grading, fill, and drainage in Largo are reviewed under Chapter 11 of the Comprehensive Development Code, which protects the city stormwater system, plus Chapter 8 general design standards that address site engineering and stormwater treatment. Property owners may not redirect runoff onto adjacent parcels or block established drainage paths, and significant land alteration requires city engineering review with stormwater calculations. Within the FEMA-mapped floodplain, Section 11.5 also limits fill and grading that would raise base flood elevations or reduce flood storage capacity. Largo Engineering Services coordinates with Southwest Florida Water Management District permitting for larger projects affecting regional drainage basins.
Diverting runoff onto neighbors or unpermitted grading in Largo can result in code compliance citations, mandatory restoration, civil penalties typically up to $500 per day, and possible liability for downstream property damage.
