§ 7-113. Drainage water fee.

This drainage water fee shall be imposed on all lands being developed within the present corporate limits and within one-half mile thereof either as a special building permit or as a land development. The revenues derived therefrom shall be used primarily, but not exclusively, for the development and construction of improvements to the existing storm water facilities and for the construction of additional needed storm water facilities, such as new, main interceptor lines, detention facilities, and disposal facilities to serve the developed areas. It is not the intent of this development fee to pay for the construction of on-site storm drainage facilities for any development, but to provide the major overall interceptor lines and detention facilities to serve the conglomeration of developments.

A. 

Drainage water fee calculation. This drainage water charge shall be imposed upon all new developments and lands to be improved under special building permits in the City. This charge shall not be imposed upon any already developed land within the City or within one-half mile thereof at the time of the passage of this Part 7, which is November 4, 1982. The amount of said charge or fee shall be as follows:

(1) 

For special building permits, the sum of two thousand five hundred dollars per acre if the amount of discharge is not limited by on-site detention;

(2) 

For special building permits, the sum of five hundred dollars per acre if the discharge of storm drainage waters for the development is limited to or less than 0.20 of a cfs per acre during a one-hundred-year design storm event.

(3) 

For land development, the sum or two thousand five hundred dollars per acre multiplied by the "Weighted Runoff Coefficient" as determined by Section 7-104A, Rational Method, if the amount of discharge is not limited by on-site detention. The weighted runoff coefficient shall not be less than 0.2.

(4) 

For land development, the sum of five hundred dollars per acre if the discharge of storm drainage waters for the development is limited to or less than 0.20 cfs per acre, during a one-hundred-year design storm event and provided the City engineer approves on-site detention for the development. On-site detention shall comply with the City of Evanston stormwater master plan. In computing the area of any tract of land for purposes of applying such fee, the area of any existing public street, alley way, or any canal, irrigation lateral, or natural waterway shall be deducted. The amount of said charge or fee may be changed from time to time by the governing body.

B. 

Manner and time of payment.

(1) 

All charges or fees shall be paid to the City treasurer.

(2) 

Land being developed in the City or within one-half mile thereof shall be assessed this drainage water fee prior to the execution of the subdivision agreement or special building permit. Payment shall then be made for the tract of land being developed prior to final execution of the subdivision contract or issuance of the special building permit.
