Soil erosion and sediment control measures have been designed in accordance with the Standards for Soil Erosion and Sediment Control in New Jersey and are shown on the plan. These include stormwater management, silt fence, inlet protection, stabilized construction access, and temporary and permanent stabilization
Point Discharge stability can be met by either maintaining existing peak rates of runoff for a “failure analysis” which ignores infiltration and storage below the lowest basin outlet or by demonstrating stable conditions under the proposed design. Ocean County Soil Conservation district has adopted current precipitation adjustment factors at N.J.A.C. 7:8-5.7(c), the values of which are reflected in the tables below.
