How is the land drainage fee calculated?
It is calculated with the following components: • Area of property – lot size in square metres. • Development Intensity – the measure of the portion of lot being utilized for its intended development. For residential customers the intensity of development factor is 1. For non-residential properties which are largely undeveloped or utilizing on-site stormwater management, a reduced factor may apply. Properties draining directly to the North Saskatchewan River are eligible for a credit to reduce the land drainage fee. • Runoff coefficient – the permeability of the lot’s surface (i.e. grass versus concrete), based on land zoning. The runoff coefficient for a single detached residential house is typically 0.5. However, depending on the property’s land zoning type, the runof coefficient can range from 0.20 to 0.95. • Rate – the monthly charge of 2.0121 cents/m2 of land area.
