(a) The drainage fee for nonresidential developed property shall be the ERU rate multiplied by the numerical factor obtained by dividing the total impervious area of a nonresidential developed property by the number of square feet in one ERU. The minimum drainage fee for any nonresidential developed property shall be equal to one ERU rate.

(b) In the event of newly developed nonresidential development property, the charge for the drainage fee attributable to that development shall commence, or increase in the case of additional development to property which is already developed property, upon the issuance of the certificate of occupancy for such additional development, or in the event that no certificate of occupancy will be issued for that development, or in the event development has halted, then on the date the Director or the Director’s designee determines in his reasonable judgment that the impervious area of such development is substantially established.

(c) In the event of separately metered nonresidential developed property with joint users of common impervious areas, the Director shall calculate and allocate the pro rata drainage fee among the users. Any owner or nonowner user disagreeing with the Director’s calculation or allocation may appeal such determination as provided in this article. (Ord. 19496 § 123, 12-21-10; Ord. 17059 § 18(C), 12-17-96. Code 1995 § 146-398. Formerly 14.85.080.)
