Good Afternoon Sue,
On the attached plan, the rip rap outlet pad for stream crossing 2 was reduced to the minimum length required by
DEMLR. The downstream end of the pipe has been raised to reduce the slope and follow the slope of the existing
grade. Please let me know if you need anything else in order to issue the PCN/401. Thank -you.
Sincerely,
Michael T. Brame

Mike,
I have reviewed the application material for this project and have the following comments/items that need to be
addressed:
1. The culvert design for Crossing #2 in the perennial stream indicates that the slope will be almost 4%. The
Division has found that pipes at this slope installed within piedmont streams has the significant potential to
cause upstream headcuts. Therefore we request that the culvert be designed to be installed "at grade".
2. The culvert design for Crossing #2 includes a 60" long riprap pad. This impact is significant. The Division
requests that the applicant consider alternative designs that would limit the length of the riprap pad. If
alternative designs are not feasible, please note that the Division will consider this impact to be a permanent
loss of water due to the length of the riprap pad, when combined with the culvert impacts.
i

The Division will consider this application to be "on hold" until receipt of a response to the above items.
