Please provide the results of in-field soil testing to determine the level of the
Seasonal High Water Table (SHWT).
2. Per Chapter 17 of the DWQ BMP Manual, the SHWT must be at least two feet
below the invert of the dry detention basin. Given the proximity of the dry
detention basin to the wetland, it is extremely unlikely that this separation exists.
Per the DWQ BMP Manual, the only detention devices that may be used in an
area with a high SHWT are wet detention basins and stormwater wetlands.
3. Please provide calculations to show that the drainage feature that is receiving the
flow from the BMP will be able to convey the flow without becoming eroded.
