5.6.1 Local Government Unit Subwatershed Phosphorus Load Reductions

Part of the phosphorus load reduction plan for Dutch Lake is a required reduction by the LGUs in the subwatershed of the phosphorus load contributed by existing land uses.  The requirement is a 15 percent reduction in loading from existing residential land use; 25 percent from agricultural land use; and 10 percent from other developed land use.  This reduction can be accomplished through application of BMPs such as additional street sweeping, local water quality ponds, rain gardens and infiltration swales, and agricultural BMPs that reduce erosion or treat runoff or drain tile discharge; prevention of future load increases through the conservation of lands previously identified for development; or achieving load removals in excess of  the minimum required.  The LGUs identified below must identify in their local water management plans specific steps to accomplish these minimum reductions.  The LGUs must also annually report to the District their progress toward accomplishing this requirement.
