Whereas section 9 of the municipal act, 2001, so 2001, c 25, as amended (the “Municipal Act”) states that a municipality has the capacity rights, powers and privileges of a natural person for the person of exercising its authority;
And whereas section 11 of the municipal act authorizes a municipality to pass bylaws, subject to certain rules, respecting economic, social and environmental well being of the municipality, services and things that the municipality is authorized to provide and public utilities;
And whereas section 391 of the municipal act authorizes a municipality to impose fees or charges on persons for services or activities provided or done by or on behalf of it, for costs payable by it for services or activities provided or done by or on behalf of any other municipality or any local board, and for the use of its property include property under its control;
And whereas section 398(1) of the municipal act provides that fees and charges imposed by a municipality on a person constitute a debt of the person to the municipality;
And whereas section 398(2) of the municipal act provides that a municipality may, in certain circumstances, add fees and charges to the tax roll of the property to which services, including public utilities, are supplied and collect them in the same manner as municipal taxes;
And whereas the City has, since January 1, 2011, imposed a stormwater charge to fund the operation, maintenance, renewal, and capital needs of the municipal stormwater management system;
And whereas the City has, since January 1, 2011, administered a stormwater credit program to recognize customers who implement stormwater Best Management Practices that reduce runoff and lessen the impact on the municipal stormwater system;
And whereas Council considers it necessary and desirable to maintain and update the stormwater charge and credit program to reflect current practices, ensure transparency in the costs of providing stormwater services, and support the long term sustainability of the City’s stormwater;
And whereas in establishing and updating the stormwater charge rate structure set out in this Bylaw, Council has had regard to the relationship between property characteristics, including impervious surface and property size, and the demand placed on the municipal stormwater system;
And whereas Council wishes continue the stormwater credit program and update the program to reflect current engineering standards, operational practices, program administration requirements, and the introduction of a renewal process for stormwater credits;
Therefore the municipal council of the corporation of the City of Waterloo enacts as follows:
