RE: Flowers Plantation Neuse River Parkway
Bottomless Culvert Certification
Dear Cyndi:
This letter is in reference to DWQ's request for additional information pertaining to the proposed bottomless
culvert crossing on Neuse River Parkway at Flowers Plantation in Johnston County. The proposed bottomless
culvert in question has been evaluated and designed with due consideration given to the existing topography
and physical features, minimizing impacts to the riparian buffers and avoiding impacts to the buffered stream.
Concerns with depth to bedrock and long-term stream sustainability were considered throughout this design
process and both issues have been adequately addressed. The proposed foundation design is a spread footing
that achieves required bearing without reaching bedrock. This design has been prepared based on the
geotechnical report's recommendations and adequately supports the structure without directly or indirectly
impacting the stream itself. Construction impacts to the stream will also be negated with the use of temporary
shoring.
Long-term stream sustainability concerns have been addressed through an analysis of storm events that
considered flow depth in establishing the orientation and width of the structure and foundation. Additionally,
the Owner understands DWQ's concerns and has agreed to assume maintenance responsibility of the roadway
and the structure. Periodic visual inspections will ensure that the stream is not negatively impacted by the
structure.
Sincerely,
Stocks Engineering, P.A.
