NOTE:This is an administrative completeness review, not a detailed engineering review,there may be
other issues that may be brought up during the engineering review. While not required for
administrative completeness, the following items were noted during review and may need to be
addressed during the technical review:
- Please specify side slopes of the Bioretention Cell on the detail sheet.
RESPONSE:Now side slopes were specified on Sheet C7.2 Details.
- Ensure that the media mix meets the requirements found on 15A NCAC 02H .1052 (6).
RESPONSE:Media mix updated to match the requirements on 15A NCAC 02H.1052(6).
- Note that the SHWT separation is from the lowest point of the SCM, to ensure that the SCM is
not impacting the water table. The bottom of the stone appears to be at 276.17, and the SHWT
is at 274.42.
RESPONSE:The whole bioretention cell is raised by 6". So, the bottom of stone lies more than 2'above
SHWT, which complies with MDC.
