Proposed Borrow Site #1 - Howerton Road

ECS Project 09.19179A
Dear Mr. Williams:
Mr. Michael Brame received an e-mail from you dated March 1, 2011 indicating that the
referenced application was incomplete. The correspondence requested additional information
pertaining to coffer dam impacts. The coffer dams that will be necessary to divert the water
flow during pipe installation will temporarily impact an additional 8 linear feet of stream channel
that was not disclosed in the PCN application. A copy of an updated drawing showing the
coffer dam design (including a. cross section view) is included as an attachment. During a
recent telephone conversation, you asked ECS to address the existing dam and why it cannot
be used. Heavy construction equipment will be used to cut and haul the borrow material from
the proposed borrow site. It will be necessary for dump trucks to make multiple passes each
day throughout the road construction project. The existing pond dam is old and not suitable for
use as a haul road. The heavy equipment would jeopardize the integrity of the dam and could
present a safety hazard.
Please feel free to contact me at [phone] if you have any questions concerning this
request or if additional information is required. Thank you in advance for your timely
consideration of this matter.
Sincerely,
rEECS Carolinas, LLP

Buffer Reforestation Planting Plan
Proposed Borrow Site #1 - Howerton Road
Alamance County, North Carolina
ECS Project 09.19179A
Dear Ms. Karoly:
Ms. Amy Euliss with the North Carolina Department of Environment and Natural Resources
(NCDENR), Winston-Salem Regional Office informed ECS Carolinas, LLP (ECS) that a buffer
reforestation planting plan is required as part of the 401 Water Quality Certification for the
proposed project. To satisfy the requirement, ECS has prepared a riparian planting plan in
conformance with the specifications defined in Chapter 15 of the North Carolina Department of
Environment and Natural Resources (NCDENR) Stormwater Best Management Practices Manual
(July 2007). The 30 feet closest to the stream (Zone 1) is to be reforested and the outer 20 feet
(Zone 2) will be planted in grass.
Zone 1 Planting Requirements
The planting recommendations for Zone 1 are based on the requirements of Chapter 15 of the
NCDENR, Stormwater Best Management Practices Manual (July 2007). Eleven species of native
trees and shrubs appropriate for the site based on site assessment and reference conditions have
been selected from the attached Master List of Native Plants. The list identifies several species
that are suitable for the existing site conditions. Seven tree species and four shrub species have
been selected based on suitability. They are highlighted on the attached list. It may be necessary
to plant alternatives to these species due to availability of nearby nursery stock. If it is necessary
to use alternatives, they should be selected from the attached Master List of Native Plants, and
submitted to ECS for approval.
Based on this plan, there will be approximately three or four understory trees for every canopy
tree to provide structural diversity similar to mature forests. The shrub species will be distributed
more densely at the outer edge of the riparian buffer to reduce light penetration and recolonization
by invasive exotic species.
Trees are to be planted at a density sufficient to provide 320 trees per acre and shrubs are to be
planted at a spacing sufficient to provide 1,200 shrubs per acre. To achieve these densities, trees
are to be planted at a spacing of 8 ft. x 8 ft to 10 ft x 10 ft and shrubs are to be planted at a
spacing of 3 ft. x 3 ft. to 5.ft x 5ft. The trees and shrubs to be planted in the restored riparian

buffer will be 12-18" tall. The trees and shrubs will be bare root or balled and burlapped (not
containerized stock). To attain optimal survival, plantings should be performed between
November 15th and March 15th. The attached Master List provides the number of trees required to
achieve these densities.
Zone 2 Plantino Reouirements
Zone 2 must be planted with a dense cover of grasses. Fescue and bluegrass should not be used
because they are invasive species and will compete with native vegetation for nutrients. Seeding
in Zone 2 is not to be performed during muddy or saturated conditions. Centipede and Zoysia
grasses should be planted in mid-May until late August. If plugs are used, they should be placed 6
to 12 inches apart (closer to a 6-inch separation for Zoysia since it doesn't spread as well as
Centipede), in a grid or checkerboard pattern. Plugs should be placed at a depth of one inch.
Site Conditions
Zone 1 and Zone 2 currently contain an approximate 25 to 30 year old stand of timber. In order to
construct the haul road, 0.14 acres of Zone 1 and 0.1 acres of Zone 2 will be cleared. Beneficial
species that are currently located within Zone 1 include red maple (Acer rubrum), loblolly pine
(Pinus taeda) and sweet gum (Liquidambar styraciflua). In addition, beneficial shrubs and low
lying vegetation consisting of ferns, greenbrier and hardwood saplings were observed in Zone 1.
Upon completion of the project, Zone 1 will be replanted with 45 trees and 168 shrubs to achieve
the desired planting densities (320 trees per acre and 1,200 shrubs per acre).
Site Preparation and Installation
Tree seedlings should be kept moist and should not be exposed to the air for extended periods of
time. A correctly planted tree should: 1) be planted so that the root collar is slightly below the soil
surface; 2) have the main roots nearly straight or spread out; 3) have soil firm around the roots;
and, 4) have the tree in an upright position and nearly even with the general ground surface, not
sunk in a hole or raised on a mound. When planting in either zone, the native soil is to be
scarified to a minimum depth of 4". All areas for grass plugs (if they are used) are to be raked to
a uniformly fine texture. Areas to be reseeded are to be moistened before planting if soil is dry.
Reseeded areas are to be mulched promptly following seeding activities.
Maintenance
Some seedling mortality is expected and replanting may be necessary to maintain the stand
density. Options for weed control include four to six inches of well-aged hardwood mulch, weed
control fabric, or pre-emergent herbicide. Once the seedlings have become established, the
areas will be left alone to encourage a natural ecosystem.
