Section 1.01 - Board of Stormwater Management to Operate Stormwater System

(A) Adoption of state law. The provisions of IC 8-1.5-5 are hereby adopted in their entirety, and the following entities established:

(1) A Stormwater Management Division within the East Chicago Sanitary District.

(2) A Board of Directors of the Division of Stormwater Management shall consist of Directors of the East Chicago Sanitary District.

(3) A Stormwater Management District, extending to the corporate boundaries of the City of East Chicago is hereby established for the purpose of providing for the collection and disposal of stormwater of the city in a manner which protects the public health and welfare, and for the purpose of assessing fees to pay for the cost of stormwater facilities and services. As the corporate boundaries of the city change, whether through annexation or otherwise, so shall the boundaries of the Stormwater District change.

(B) Powers of the Board. The Board of Directors of the Division of Stormwater Management shall have exclusive jurisdiction over the collection and disposal of stormwater within the District, and shall possess all the powers and duties set forth in IC 8-1.5-3-4 and 8-1.5-5-6 including but not limited to the power to:

(1) Establish and enforce rules and regulations governing the Division of Stormwater Management.

(2) Hold hearings following public notice.

(3) Make findings and determinations.

(4) Install, maintain and operate a stormwater collection and disposal system.

(5) Make all necessary or desirable improvements of the grounds and premises under its control.

(6) Recommend to the Common Council reasonable and just rates and charges for services to the customers of the District.

Section 1.02 Purpose & Objective

(A) The function of the Division of Stormwater Management is to provide for the safe and efficient capture and conveyance of stormwater runoff; mitigate the damaging effects of stormwater runoff; correct stormwater collection and conveyance problems; and fund the activities of stormwater management including design, planning, regulation, education, coordination, construction, operation, maintenance, inspection and enforcement activities, all for the protection of the public health, welfare and safety. It is the further function of the Division of Stormwater Management to insure the city's compliance with its NPDES stormwater discharge permit(s).

(B) It is hereby determined necessary for the protection of public health, safety and welfare and to conform with federal, state and local laws and regulations that a system of charges for stormwater service in the city be established which allocates the cost of providing stormwater service to each user in such a manner that the charges assessed are proportionate to the cost of providing stormwater service to that user, insofar as those costs can reasonably be determined.
