Summary

New Britain's Flood Damage Prevention ordinance requires new construction or substantial improvement of any residential structure in a special flood hazard area to have its lowest floor, including the basement, elevated at least two feet above the base flood elevation. The city engineer administers floodplain management permits and enforces the two-foot freeboard standard citywide.

a.Residential construction: New construction or substantial improvement of any residential structure shall have the lowest floor, including basement, elevated at least two (2) feet above the base flood elevation. ... Any person who violates this article or fails to comply with any of its requirements shall be subject to a fine of ninety-nine dollars ($99.00) and to a further penalty of not less than ninety-nine dollars ($99.00) for each and every day that such violation continues to exist.

Full Breakdown

Article III of the Code of Ordinances, adopted under the authority of Connecticut General Statutes section 7-148(c)(7), governs development within New Britain's special flood hazard areas, mapped by FEMA as zones A, AE and A1-30 on the Flood Insurance Rate Maps dated May 16, 2017 (Panel 09003C0487G) and September 26, 2008. Under section 9-45(c)(1)a., new construction or substantial improvement of a residential structure must have its lowest floor, including any basement, elevated at least two feet above the base flood elevation; nonresidential structures face the same two-foot freeboard unless floodproofed to the standards of section 9-45(c)(1)b.

A floodplain management permit from the city engineer, required by section 9-43(c) before any development activity begins, expires if work does not start within ninety days. Applicants must submit certifications from a registered professional engineer, surveyor or architect confirming the elevation of the lowest floor in relation to mean sea level, and the city engineer records that elevation once construction is complete. Fully enclosed areas below the base flood elevation must have at least two flood vents with a net area of one square inch per square foot of enclosed space, and may only be used for parking or storage, never as finished living space.

The flood and erosion control board hears variance requests and appeals from the city engineer's decisions; appeals from the board go to the Superior Court for the Judicial District of New Britain within fifteen days under section 8-8 of the General Statutes.

Violations & Fines

Violating any requirement of Article III, including building below the required two-foot freeboard, carries a fine of ninety-nine dollars under section 9-50, plus a further penalty of at least ninety-nine dollars for every day the violation continues. The city engineer may also order a stop-work order through the chief building inspector and require correction of deficient lowest-floor elevations before construction proceeds.

Frequently Asked Questions

How high above the base flood elevation must a New Britain home be built?
Section 9-45(c)(1)a. of the Code of Ordinances requires new construction or substantial improvement of any residential structure in a special flood hazard area to have its lowest floor, including the basement, elevated at least two feet above the base flood elevation shown on FEMA's Flood Insurance Rate Map for New Britain.
Who administers New Britain's flood elevation rules?
The city engineer is designated under section 9-44(a) to administer, implement and enforce Article III, Flood Damage Prevention, including reviewing floodplain management permit applications, verifying elevation certifications from registered engineers or architects, and taking enforcement action against noncompliant construction under section 9-49 of the Code of Ordinances.
What happens if a structure is built below the required elevation?
The city engineer issues a written order to cease the activity and either obtain a permit or remove the violation, notifies the chief building inspector to suspend any building permit and issue a stop-work order, and the violator faces a ninety-nine dollar fine plus ninety-nine dollars for each day the violation continues under section 9-50.
Can a New Britain property owner get a variance from the flood elevation requirement?
The flood and erosion control board may grant a variance under section 9-47 upon a showing of good and sufficient cause and exceptional hardship based on the property's unusual physical characteristics, but never for structures within a designated floodway if the variance would increase flood levels during the base flood discharge.
