Summary
Property owners in unincorporated Manatee County must maintain any stormwater drainage facility on their land that principally collects that property's own runoff, and get the public works director's written approval before altering it. The county's separate stormwater management system, created under Sec. 2-10-51 et seq., is funded by utility fees and assessments, with the director authorized to inspect private facilities and order remedial maintenance at the owner's cost.
The property owner shall be responsible for stormwater drainage facilities located on private property where runoff will principally be collected within that property. The owner shall clean and maintain the facility or channel, as required, to ensure efficient and proper operation of the facility, and shall obtain the director's prior written approval for any proposed changes or alterations to any private stormwater drainage facilities that, in the county's sole discretion, may substantially or adversely affect stormwater drainage in the property owner's area. The director shall provide for inspection of private facilities to ascertain that the stormwater facilities are functioning as designed and approved. The director shall provide for remedial maintenance of facilities based upon the severity of stormwater problems and potential hazard to the public health, safety and welfare. The director is authorized to charge reasonable fees for such inspections and for the costs of such remedial action.

Full Breakdown
Sec. 2-10-75 puts the burden of private drainage on the landowner: the owner must clean and maintain any facility or channel that principally collects runoff generated on that parcel, and must get the director's prior written approval before changing or altering it if the change could, in the county's sole discretion, substantially or adversely affect drainage in the area. The director can order an inspection of private facilities at any time to confirm they function as designed, require remedial maintenance based on the severity of the problem and the hazard it poses, and charge the owner reasonable fees for both the inspection and the remedial work.
Parallel to this private-facility duty, the county operates a county-wide stormwater management system under Sec. , funded through stormwater management assessments, stormwater utility fees, permit and inspection fees, impact fees, and development capital contributions (Sec. 2-10-76). Owners who receive an on-site retention or detention adjustment to their assessment must submit to an annual inspection and pay an inspection fee set by the director (Sec. 2-10-73(b)). Sec. 2-10-78 makes clear the county carries no liability for flood damage that exceeds what the constructed drainage system can handle, and that paying a stormwater assessment or fee does not substitute for flood insurance.
Unpaid stormwater management assessments become a lien on the property from the first day of the assessment year until paid, collectible the same way a mortgage is foreclosed, with the county entitled to recover court costs and attorney's fees (Sec. 2-10-74).
Violations & Fines
Altering a private drainage facility without the director's prior written approval exposes the owner to a county-ordered inspection and mandatory remedial maintenance, billed back to the owner at the director's discretion (Sec. 2-10-75). Unpaid stormwater management assessments become a lien enforceable by foreclosure-style action, with the county recovering court costs and reasonable attorney's fees on top of the assessment itself (Sec. 2-10-74).
