B3a. Explain the purpose of the proposed project:
The purpose of the project is to install a gravel driveway and stable stream crossing in a manner
consistent with Town of Black Mountain, NC DWR and USACE regulations while minimizing impacts
to stream buffers.
B3e. Describe the overall project in detail, including the type of equipment to be used:
Project Sequence:
1.Transplant high quality native plants (rush, sedge, grass, tree/shrub saplings) using hand tools
and small tracked excavator from driveway footprint to provided containers and be staged on
provided trailer for reuse in streambank stabilization.
2.Place 4 oz. nonwoven filter fabric (fabric) at 12’ width from Avena Road to tributary (trib.)
over driveway footprint.
a.
3.Place ~4” depth/thickness of 3-inch ballast stone on fabric from Avena Road to trib.
4.Install 48” diameter, 20’ length culvert in trib. In accordance with NC State Water Quality
General Certification NO. 4139 Section II Condition 11.
5.Construct boulder (2’H x 2’W x 3’L min boulder dimensions) headwall and endwall at
upstream and downstream ends of culvert location.
a.Back and underlay fabric behind and below boulders.
b.Backfill behind fabric/boulders with ABC/road-bond/crusher run.
6.Extend fabric over culvert to 30-feet rear lot setback boundary (approximately 112’).
7.Backfill culvert to bottom elevation of ballast elevation with ABC stone.
a.Ensure culvert manufacture specification for coverage is/will be met with final grade.
8. Install 3” topcoat ABC/Road-bond over entire drive including culvert.
9.Remove existing 20’ length failed culvert downstream of new culvert from stream and restore
approximately 60 linear feet of streambank (see figure 1).
a.Transplant high quality vegetation from failed culvert location to provided
containers/trailer.
b.Remove culvert and place culvert and all unwanted material directly into truck or trailer
for proper disposal.
c.Grade and compact streambanks in the area where the culvert was removed to
blend/match existing streambanks upstream and downstream of removal area.
d.Carefully install 10-10-10 fertilizer per manufacture specifications (MS) on streambank
keeping fertilizer out of water.
e.Install ERNST ENRMX-Riparian Mix (https://www.ernstseed.com/product/riparian-
buffer-mix/?anchor=65) or equal and annual grain appropriate for season to disturbed
areas per MS.
f.Install containerized herbaceous transplants in disturbed areas.
g.Install 400 oz/m2 coir fabric over all disturbed areas below the top of the streambank
per MS.
h.Mulch disturbed areas above top of bank with wheat straw at 75% soil coverage
Mair Driveway PCN Additional Sheets July 1, 2020
During removal of failed culvert and streambank grading in the failed culvert area, culvert
installation/removal and culvert headwall construction, stream flow will be pumped around the project
area. A filter bag(s) will be used to trap sediment at the downstream end of the pump around system
before discharging to the stream. Turbidity in the stream will be minimized and kept below 50 NTU.
The project area will be irrigated in periods of dry weather until a six-inch stand of temporary
grassy/grain vegetation is established over the disturbed areas.
Equipment used on the site will include small track mounted excavators and loaders (18,000 lbs. each),
compactors and various hand tools.
