Exeter Municipal Code Ch. 13.36 Storm and Surface Drainage

It is unlawful to connect directly or indirectly to the city's sanitary sewer system any drain which will carry stormwater or irrigation water or other pure water runoff from private property or structures.

(Ord. 305 §1, 1973)

A. Where temporary disposal of storm water is required, such disposal may be made in temporary basins which shall be built to city standards. The area of the ponding lot shall be one lot for each twenty lots in a subdivision based on the average lot size; and where an overflow connection may be made to the sanitary sewer, the ratio shall be one lot for each thirty lots in the subdivision, based on the average lot size, but such overflow connection to the sanitary sewer shall only be made upon approval of the city engineer.

B. All areas used for temporary ponding basins shall be deeded to the city with reversionary rights to the grantor, if the ponding basins may be abandoned within seven years. If the ponding basin is still in use at the end of seven years, the property shall then become vested, without rights of reversion, to the city. When a ponding basin is constructed, the value of the lot may be deducted from the drainage fee. At such time as the ponding basin is abandoned, and prior to the reversion, such drainage fee shall be paid to the city.

(Ord. 305 §2, 1973)

A. The maximum distance permitted for surface drainage in developments within the city is one thousand three hundred feet.

B. Crossdrains at street intersections, necessary catchbasins, storm drains, and connections therefrom to sewers or drains shall be installed by the subdivider in accordance with specifications of the city.

(Ord. 305 §3, 1973)

The city shall assume no financial obligation for extending public storm drains to any subdivision or development.

(Ord. 305 §4, 1973)

When it is not possible for the subdivider or developer to provide for ultimate disposal, and a connection is made to an existing storm drain line which has been previously installed, payment shall be made to the city according to the type of development, and the fees shall be adopted by the city council by resolution.
