In the Mustoja basin, the directly connected impervious area or DCIA was determined to be 26.8% of the total land use area (see Table 3).
For EIA directly connected impervious areas (DCIAs) need to be accounted because the part that is not directly connected to storm drainage has less impact on the output (Lee and Heaney, 2003; Ebrahimian et al., 2016).
Bids were collected, ranked in ascending order, and then weighted on the basis of objective criteria that would affect effectiveness (e.g., area of directly connected impervious area
, soil runoff potential, and proximity to a stream reach).
* Implementing planning requirements to minimize the amount of directly connected impervious areas
and to incorporate buffer strips, open space, and structural BMPs to control runoff from new developments.
