Proposed:
Please refer to the attached underground level spreader (ULS) detail plan sheet. We
are proposing to place this ULS between the above-seen silt fence and the small ridge at the
rear of the homes. This location was determined to be the best since it is directly below the
small hill behind the homes and furthest from the stream. All of the stone will be removed.
The outlet pipe will be extended 20-feet to a T-fitting. This T-fitting will have approximately
32-feet of pipe extending from it east and west. The outlet pipe will consist of 15-inch
diameter perforated plastic pipe surrounded by gravel. North American Green P300 fabric
will be placed along the surface to facilitate the growth of the new grass.
Options such as bioretention and above ground level spreaders were considered.
However, these did not remove the safety and other concerns of the above-ground
discharge. Secondly, it does not appear that there is sufficient area for a bioretention cell
within Zone 2 and DWQ staff has informed us that they do/will not recommend a major
variance to the NCEMC. The topography behind the homes is also very conducive to the
ULS since they are narrow and can fit within the confines of the small ridge and Zone 1
buffer line. Upon completion of the ULS installation, we will conduct regular monitoring to
ensure its success. This includes video-documentation and providing it to your offices.
Stormwater:
The drainage basin for this stormwater outlet encompasses approximately five lots
and 0.75-acre. The drainage basin is entirely built-out. This ULS will provide the necessary
sheet flow into the adjacent riparian area. The current discharge of the RCP is 4.7 CFS and
the 15-inch diameter ULS should clearly handle the storm events.
