Dear Dennis, Charlie and Jason:
I have spoken with Dennis and Charlie this morning and I have agreed to allow the ponds to
remain in their currently proposed locations as long as the issue of the seasonal high
groundwater table (SHWT) can be addressed. Charlie has done a boring at the proposed
locations of the two ponds and has determined that the SHWT is only 18-14 inches below the
ground surface. Charlie suggests that surveying needs to be done to determine the
elevations of the boring locations to assist with the pond design. As the October 29, 2008
Request for More Information letter states, the permanent pool elevation of the ponds must
be at or above the level of the SHWT to assure that the adjacent wetlands are not dewatered.
In the resubmittal for this project, please include:
- Results from the soil tests,
- Updated pond design plans if a redesign was necessary to protect the adjacent wetlands
(see the Required Items Checklist for Wet Detention Ponds for guidance about what should be
included - on the cross-section of the ponds, be sure to depict the SHWT), and
- A planting plan for the vegetated shelves of the wet detention ponds.
Please feel free to contact me if you have any questions.
Sincerely,
Annette Lucas
