§ 141-13. Duties of Planning and Zoning Commission.

The duties of the Rocky Hill Planning and Zoning Commission shall include, but not be limited to:

A. 

Permit review. The Planning and Zoning Commission shall:

(1) 

Review all development permits to determine that the permit requirements of this chapter have been satisfied.

(2) 

Review all development permits to determine that all necessary permits have been obtained from those federal, state or local governmental agencies from which prior approval is required.

(3) 

Review all development permits to determine if the proposed development adversely affects the flood-carrying capacity of the area of special flood hazard. For purposes of this chapter, "adversely affects" means that the cumulative effects of the proposed development, when combined with all other existing and anticipated development, increases the water surface elevation of the base flood more than one foot at any point.

B. 

Use of other base flood data.

(1) 

When base flood elevation data has not been provided in accordance with § 141-4, Basis for establishing areas of special flood hazard, the Rocky Hill Planning and Zoning Commission shall obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer § 141-18.

(2) 

When utilizing data other than that provided by the Federal Emergency Management Agency, the following standard applies: Select and adopt a regulatory floodway based on the principle that the area chosen for the regulatory floodway must be designed to carry the waters of the base flood without increasing the water surface elevation more than one foot at any point.

C. 

Information to be obtained and maintained. The Planning and Zoning Commission shall:

(1) 

Obtain and record the actual elevation, in relation to mean sea level, of the lowest habitable floor, including basement, of all new or substantially improved structures.

(2) 

For all new or substantially improved floodproofed structures:

(a) 

Verify and record the actual elevation, in relation to mean sea level; and

(b) 

Maintain the floodproofing certifications required in § 141-11C.

(3) 

Maintain for public inspection all records pertaining to the provisions of this chapter.

D. 

Alteration of watercourses. The Planning and Zoning Commission shall:

(1) 

Notify the Rocky Hill Open Space and Conservation Commission, Adjacent communities, applicable regional planning agencies and the Connecticut Department of Environmental Protection prior to any alteration or relocation of a watercourse and submit evidence of such notification to the Federal Insurance Administration.

Editor's Note: See Ch. 42, Open Space and Conservation Commission.

(2) 

Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is not diminished.

E. 

Interpretation of FIRM boundaries. The Planning and Zoning Commission shall make interpretations, where needed, as to the exact location of the boundaries of the areas of special flood hazard (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in § 141-15.
