Description: Summary of impervious cover in reach contributing areas. Impervious surface was measured as a runoff coefficient using the Directly Connected Impervious Surface Cover/Area (DCIA; TRCA 2019). Using the total impervious area values, imperviousness was weighted in relation to the total amount of land cover types for a reach contributing area.
