(A) Stormwater shall be managed in accordance with the National Urban Runoff Program (NURP) standards for the design of new stormwater ponds. The provisions of the Minnesota Pollution Control Agency’s urban “best management practices,” titled “Protecting Water Quality in Urban Areas,” shall be used to review any proposed development in order to reduce non-point source pollutant loadings in stormwater runoff.
(B) Existing natural drainageways, natural water storage or retention areas, and vegetated soil surfaces should be used to the greatest extent possible to store, filter and retain stormwater runoff before discharge occurs into any public waters. When natural features and vegetation are not available to handle stormwater runoff, constructed facilities such as diversions, settling basins, skimming devices, dikes, and man-made waterways and ponds may be used. Preference shall be given to designs using surface drainage, vegetation, and infiltration rather than buried pipes and man-made materials and facilities. Development should be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes.
