VEGETATION SELECTION
The following table lists the woody \egetation for the project site. Exact spacing
densities and placement of species will be determined prior to site planting by a
qualified \egetation specialist based on current site conditions and apparent wetness
of planting locations, as defined in the construction specifications. The total planting
area is estimated to be approximately two (2) acres but may vary based on areas
disturbed during construction.

PLANTING NOTES SUMMARY:
1. THE PLANTING ACTIVITIES SHALL ADHERE TO THE CONSTRUCTION SPECIFICATIONS
AS DEFINED IN SECTIONWAND AS SHOWN ON THE PLAN DETAILS. SEE SHEET I-A
FOR VEGETATION SELECTION TO BE PLANTED WITHIN THE CONSERVATION EASEMENT
2. THE EXACT SPECIES PLACEMENT WILL BE DETERMINED PRIOR TO SITE PLANTING BY
A QUALIFIED VEGETATION SPECIALIST BASED ON SPACING RECOMMENDATIONS,
SITE CONDITIONS, AND APPARENT WETNESS OF PLANTING LOCATIONS. ANY CHANGES TO
THE PLANTING LOCATIONS, SPACING DENSITIES, OR VEGETATION SELECTION
MUST BE APPROVED BY THE ENGINEER BEFORE PLANTING BEGINS.
3. THE SUPPLEMENTAL PLANTING AREAS TOTAL APPROXIMATELY TWO (2) ACRES
BUT MAY VARY BASED ON AREAS DISTURBED DURING CONSTRUCTION.
ANY ENCROACHMENTS WITHIN THE PLANTING AREAS SUCH AS CULVERTS,
DRAINAGE OUTFALLS, UTILITY EASEMENTS, TRAILS, ETC. WILL BE IDENTIFIED PRIOR
TO PLANTING ACTIVITIES.
4. THE CONTRACTOR SHALL INSTALL ALL VEGETATION DURING THE APPROPRIATE SEASON
FOR EACH SPECIES TYPE. THE PLANTING SEASON FOR THE TREES, SHRUBS, AND LIVE STAKES
SHALL BE FROM DECEMBER TO FEBRUARY AS DESCRIBED IN THE CONSTRUCTION SPECIFICATIONS.
NO PLANTING SHALL OCCUR IF THE SOIL IS FROZEN.
CONSTRUCTION SEQUENCE - ELLERBE CREEK
Michael Baker Engineering, Inc. will provide construction observation during the construction phase of this project
The following construction sequence shall be used during implementation of the plan.
1. Prior to beginning any land disturbing activities, notification and approval must be granted from the US Army Corp
of Engineers, NC Division of Water Quality, and NCDENR Division of Land Resources - Land Quality Section. Any
work performed shall be in accordance with the NC Erosion Control Planning and Design Manual.
2. The Contractor shall contact North Carolina "One Call" Center (1.800.632.4949) and Land Quality (919.791.4210)
before any excavation begins.
3. The Contractor shall mobilize equipment and materials to the site using the construction entrances off Albany St.
(upstream), Carolina Ave., and Guess Rd. (downstream) and install temporary construction entrances according to
the plans and specifications.
4. The Contractor shall install silt fence and safety fence before storing all equipment and materials in staging areas
as shown on the plans.
5. The Contractor shall utilize the haul roads and temporary stream crossings as shown on the plans.
6. Channel work within the active stream shall be conducted while stream flow is low. In general, the Contractor
shall work from upstream to downstream and in-stream structures shall be installed using a pump around or flow
diversion measure. Bank protection includes transplants, brush mattresses, geolifts, and/or seeding with matting.
Silt fence shall be placed between stockpiles and the existing channel as shown on the plans.
7. Immediately upon completion of bank grading, the slopes will be reseeded and matted with the specified erosion
control matting. The Contractor shall not disturb any area larger than they can completely stabilize in one day. All
disturbed stream banks must be stabilized by the end of each day.
8. Upon completion of the channel work and bank stabilization, all disturbed areas including staging areas and haul
roads, shall be seeded and covered with mulch. Permanent seeding mixtures shall be applied as shown on the
vegetation selection. Temporary seeding shall be applied in all areas susceptible to erosion (i.e. disturbed ditch
banks, steep slopes, and spoil areas) such that ground cover is established within 21 working days following
completion of any phase of grading. Permanent ground cover shall be established for all disturbed areas within 15
working days or 90 calendar days (whichever is shorter) following completion of construction.
9. The Contractor shall remove temporary stream crossings and erosion control measures. All waste material must
be removed from the project site.
10. The Contractor shall plant woody vegetation, live stakes, and apply permanent seeding at the appropriate time of
the year and as described in the planting details and specifications.
11. The Contractor shall ensure that the site is free of trash and leftover materials prior to demobilization of
equipment from the site.
