For new construction, roof drains and sump pumps shall not connect directly to streets, sanitary or storm sewers or roadside ditches in order to promote overland flow and infiltration/percolation of stormwater. When it is not practical for roof drains and sump pumps to discharge to vegetative areas or infiltration BMPs, the City may permit roof drain and sump pump connections to streets, storm sewers or roadside ditches on a case-by-case basis upon recommendation by the City Engineer.
