Development Engineering, LLC 550 Colfax Road Wayne, NJ 07470 (973) 835-0340 The variability of soil permeability test results shall be considered acceptable only where the results of all replicate tests fall within one soil permeability class or two adjacent permeability classes. New Jersey Storm Water BMP Manual Appendix E defines soil permeability classes as follows: Measured Soil Permeability Greater Permeability than (in/hr) Class 20 K5 6-20 K4 2-6 K3 0.6-2 K2 0.2-0.6 K1 Less than 0.2 K0 Based on the field results, the subject soil permeability class is K3 which is very suitable for installation of the proposed seepage pit.
