The developer needs to submit maps to <br />Mn/DOT Metro District Water Resources Engineering showing pre- and post - <br />construction drainage areas with time of concentration flow paths and soil information for <br />the complete drainage area. The maps should be accompanied by drainage con putations <br />for pre- and post- construction conditions during 10 and 100 year events.
