C. 36-7-4, governs development in mapped flood hazard areas across the unincorporated county. 18 bars any structure from being located, extended, converted or structurally altered within the SFHA, or any land or stream within the SFHA from being altered, without full compliance with the chapter.

Violations & Fines

Failure to obtain a floodplain development permit, or failure to comply with permit requirements or variance conditions, is a violation of Chapter 155 under § 155.99. Every violation is treated as a common nuisance under the County's Zoning Code and is punishable by a fine not exceeding $2,500, with each day the violation continues counted as a separate offense. The County Plan Commission also notifies the property owner that a willful violation may cause a standard flood insurance policy to be suspended, and the county may pursue any other lawful remedy, with costs charged to the responsible party.

Frequently Asked Questions

Do I need a permit to build in a LaPorte County flood zone?

Yes. Section 155.17 requires a floodplain development permit before any development activity begins in a mapped special flood hazard area, including construction, grading, filling or structural alteration. Apply through the County Building Commissioner, who administers Chapter 155 as the Floodplain Administrator.

What happens if I build without a floodplain permit?

Section 155.99 makes the failure to obtain a permit, or to follow its conditions, a violation punishable by a fine of up to $2,500 for each day the violation continues. The county also treats the violation as a common nuisance under its Zoning Code and can pursue other lawful remedies at the violator's cost.

How many inspections does the county require?

Section 155.32(B)(13) requires at least three inspections: one at the flood protection grade reference mark, one when the structure's lowest floor is established, and a final inspection when the applicant submits the completed FEMA elevation certificate.

Can my flood insurance be affected by a violation?

Yes. Under § 155.99(B), the County Plan Commission will inform an owner that a willful violation is considered an act that increases flood damages, which may cause a standard flood insurance policy on the property to be suspended.
