STREAM RELOCATION
Olde Towne

PROJECT DESCRIPTION + NEED

Olde Towne is a proposed 574-acre master planned community comprised of five residential sub -communities, a
commercial district, amenity center, greenways, a multi-use path, a road network and public gathering spaces located
at the northeast quadrant of S. New Hope Road and Rock Quarry Road in southeast Raleigh, North Carolina. The
project’s purpose is to create a large -scale master-planned community to meet the current demand for residential
housing mixed with commercial space near downtown Raleigh. To move forward with the Olde Towne development,
offsite road improvements on Rock Quarry Road were required by TIA for Phase 1. Widening of Rock Quarry Road
results in impacting 351 lf of existing stream channel, requiring mitigation as part of the project’s issuance of an Induvial
Permit and Water Quality Certification. To offset impacts of widening Rock Quarry Rd, 351 lf of stream was relocated
using natural channel design techniques.

The restored stream was designed to have natural channel dimension, pattern, profile, and vegetation based on
regional stream data. The stream was relocated and connected to the surrounding forested floodplain using a “Priority
One” approach of grading the channel so that bankfull stage (incipient flooding) was at the elevation of the existing
floodplain area with minor floodplain grading to provide sufficient flood prone area width to dissipate hydraulic energy
during bankfull and greater flood events. This geomorphic condition will be sustained by increased sinuosity, creation
of a stable slope, and grading appropriate channel depth and width for stability, thereby reducing bankfull shear stress
and velocity. Stream longitudinal profile and bedform diversity were improved with the design of riffle and pool
sequences and incorporation of log structures for habitat diversity and grade control. The streambanks and surrounding
floodplain will be planted extensively with native riparian and wetland vegetation to establish a native forested riparian
plant community.

DESIGN MODIFICATIONS

During the onsite pre-construction meeting, it was requested to protect additional existing hardwood trees in the
project area. Trees on the plans and identified in the field were flagged to be avoided by the stream restoration work.
As a result, the proposed stream channel alignment was modified slightly during construction as a field change,
specifically between stations 1+30 to 2+00 to protect the mature trees and their extensive root systems.

Another design modification included stabilizing the proposed stream channel at its downstream tie-in with the existing
stream channel. Onsite rock equivalent in size to Class ‘B’ riprap was embedded in the channel bottom from stations
3+50 to 3+56 to protect against potential erosion in the channel bed. The top of stone matches channel bottom grade
and the bank area was stabilized with erosion control matting and permanently protected with riparian vegetation.

During construction, the relic stream channel was observed to overtop the constructed channel plug prior to its
connection with the relocated stream channel. The future road widening will fill in the remaining relic channel and
prevent this from occurring in the future. Therefore, in order to protect the channel plug in this interim condition, a
log sill was buried at the upstream end of the channel plug and installed perpendicular to the relic stream channel.
Additionally, temporary sandbag sills were placed on top of the channel plug within the floodplain and angled towards
the proposed stream channel, promoting dissipated flow across the floodplain and into the relocated stream channel.

AS-BUILT CONDITION

At the time of as-built survey, two cross sections, 1 riffle and 1 pool were selected and surveyed to establish a baseline
geometry for monitoring. A centerline survey was also performed to determine total restored length of 369 linear feet
of the stream channel. The as-built centerline and location of the cross sections and their surveyed geometry points
can be found on the as-built survey prepared by the John R. McAdams company signed May 10, 2021. Approximate
location of the cross sections is shown on the as-built record drawings.

General condition of the channel and surrounding project area can be observed in the attached photo journal. It should
be noted that sediment load contributed from upstream reach has resulted in sediment deposition within the
restored/constructed channel. Photos taken at time of construction completion should be considered the baseline
condition for monitoring.

TEMPORARY SEEDING SCHEDULE:
TEMPORARY SEEDING SHALL BE APPLIED AS NEEDED DURING CONSTRUCTION TO STABILIZE BARE OR DISTURBED AREAS OF SOIL AND AT
THE COMPLETION OR ALL GRADING AND EARTHWORK ACTIVITIES WITHIN A PARTICULAR AREA OF THE SITE. PERMANENT SEED MAY BE
DISTRIBUTED WITH TEMPORARY SEED UPON THE FINAL APPLICATION OF TEMPORARY SEED.
SEEDING DATE SEEDING MIXTURE APPLICATION RATE
AUG 15 - MAY 1 RYE (GRAIN) 30 LBS/AC
AUG 15 - MAY 1 WHEAT 30 LBS/AC
MAY 1 - AUG 15 GERMAN MILLET 10 LBS/AC
MAY 1 - AUG 15 BROWNTOP MILLET 10 LBS/AC
SEEDING METHODS
1.EVENLY APPLY SEED USING A CYCLONE SEEDER, DRILL, CULTIPACKER SEEDER, OR HYDROSEEDER. THIS MUST BE DONE WITHIN 48
HOURS OF LAND DISTURBING ACTIVITIES.
2.MULCH WITH CLEAN WHEAT STRAW.
3.AFTER SEEDING, APPLY MULCH TO AREAS UNDER HARSH CONDITIONS SUCH AS AREAS THAT HAVE BEEN GRADED, OR THOSE WHICH
WILL RECEIVE CONCENTRATED FLOWS. AREAS CONSIDERED TO BE UNDER HARSH CONDITIONS WILL BE CONSIDERED THE AREAS
GRADED FOR THE WETLAND VALLEY.
4.RESEED AND MULCH AREAS WHERE SEEDLING EMERGENCE IS LESS THAN 80% COVERAGE, OR WHERE EROSION OCCURS, AS SOON
AS POSSIBLE. DO NOT MOW. PROTECT FROM TRAFFIC AS MUCH AS POSSIBLE.
NOTES
1.TEMPORARY ANNUAL SEED SELECTION SHOULD BE BASED ON SEASON OF PROJECT INSTALLATION.
2.A SINGLE SPECIES FOR TEMPORARY COVER IS ACCEPTABLE
3.IN SOME CASES WHERE SEASONS OVERLAP, A MIXTURE OF TWO OR MORE SPECIES MAY BE NECESSARY. HOWEVER, APPLICATION
RATES SHOULD NOT EXCEED THE TOTAL RECOMMENDED RATE PER ACRE.
4.TEMPORARY SEED SHOULD BE MIXED AND APPLIED SIMULTANEOUSLY WITH THE PERMANENT SEED MIX IF OPTIMAL PLANTING
DATES ALLOW.
PERMANENT SEEDING SCHEDULE:
PLANT MATERIAL SELECTION
1.REFER TO TABLE 6.24C BELOW FOR APPROPRIATE SELECTIONS OF NATIVE PERMANENT SEEDS.
2.PERMANENT SEED INCLUSION IN THE MIXTURE SHOULD TOTAL 15 LBS OF PURE LIVE SEED (PLS) PER ACRE DRILLED OR 15-20 LBS
pls/AC BROADCAST APPLIED.
3.AT LEAST 4 SPECIES SHOULD BE SELECTED FOR THE MIXTURE INCLUDING ONE SPECIES FROM EACH TYPE (WARM SEASON, COLD
SEASON, WETLAND). SELECTION OF MORE THAN 4 SPECIES IS RECOMMENDED FOR INCREASING CHANCES OF SUCCESSFUL
VEGETATION ESTABLISHMENT.
4.IF OTHER SPECIES SUCH AS WILDFLOWERS ARE ADDED TO THE MIX, THEY SHOULD NOT BE COUNTED IN THE MINIMUM SEEDING
RATE FOR GRASSES.
SEEDBED PREPARATION
1.DISTURBED SOILS WITHIN RIPARIAN AREAS MUST BE AMENDED TO PROVIDE AN OPTIMUM ENVIRONMENT FOR SEED
GERMINATION AND SEEDLING GROWTH.
2.THE pH OF THE SOIL MUST BE SUCH THAT IT IS NOT TOXIC AND NUTRIENTS ARE AVAILABLE.
3.SOIL ANALYSIS SHOULD BE PERFORMED TO DETERMINE NUTRIENT AND LIME NEEDS OF EACH SITE.
4.APPROPRIATE pH LEVELS ARE BETWEEN 5.5 - 7.
5.RIPARIAN BUFFERS REGULATED FOR NUTRIENT MANAGEMENT MAY BE LIMITED TO A SINGLE APPLICATION OF FERTILIZER.
6.SUITABLE MECHANICAL MEANS SUCH AS DISKING, RAKING, OR HARROWING MUST BE EMPLOYED TO LOOSEN COMPACTED SOIL
PRIOR TO SEEDING.
PLANTING
1.APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP-TYPE SPREADER, DRILL, OR HYDROSEEDER ON A FIRM, FRIABLE SEEDBED.
2.IN FINE SOILS, SEEDS SHOULD BE DRILLED 0.25 - 0.5 INCHES. IN COARSE SANDY SOILS, SEEDS SHOULD BE PLANTED NO DEEPER THAN
0.75 INCHES.

1.MULCH ALL PLANTINGS IMMEDIATELY AFTER SEEDING.
2.IF PLANTING ON STREAM BANKS STEEPER THAN 10% OR AREAS SUBJECT TO FLOODING, A BIODEGRADABLE ROLLED EROSION
CONTROL PRODUCT IS RECOMMENDED TO HOLD SEED AND SOIL IN PLACE.
MAINTENANCE
1.THE RECOMMENDED PERMANENT GRASS SPECIES MAY REQUIRE TWO YEARS FOR ESTABLISHMENT, DEPENDING ON SITE
CONDITIONS.
2.INSPECT SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS, SOIL AMENDMENTS, AND RE-SEEDINGS.
3.IF WEEDY EXOTIC SPECIES HAVE TAKEN OVER THE AREAS AFTER THE FIRST GROWING SEASON, THE INVASIVE SPECIES MUST BE
ERADICATED TO ALLOW NATIVE SPECIES TO GROW.
4.MONITOR THE SITE UNTIL LONG-TERM STABILITY HAS BEEN ESTABLISHED.
SEEDBED PREPARATION
1.CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3-4 INCHES DEEP OVER ADVERSE SOIL CONDITIONS. TOPSOIL SHOULD BE
INCORPORATED INTO THE FINAL GRADING OF THE BASIN SIDE SLOPES AND SHALLOW LAND AND SHALLOW WATER AREAS.
CONTRACTOR SHOULD SCARIFY THE TOP 3-4 INCHES OF THE COMPACTED FILL TO PROMOTE BONDING WITH TOPSOIL.
2.RIP THE ENTIRE AREA TO 6 INCHES DEPTH.
3.REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER OBSTRUCTIONS LEAVING SURFACE REASONABLY SMOOTH AND UNIFORM.
4.PER ONE TIME ONLY, APPLY AGRICULTURAL LIME, FERTILIZER, AND SUPERPHOSPHATE UNIFORMLY AND MIX WITH SOIL.
5.CONTINUE TILLAGE UNTIL A WELL-PULVERIZED, FIRM REASONABLY UNIFORM SEEDBED IS PREPARED 4 TO 6 INCHES DEEP.
6.SEED ON A FRESHLY PREPARED SEEDBED AND COVER.
7.ONCE SEED MIX HAS BEEN APPROPRIATELY APPLIED TO THE AREA, COVER WITH EROSION CONTROL BLANKET IMMEDIATELY (SEE
DETAIL SHEET C9.2).
8.INSPECT ALL SEEDED AREAS AND MAKE NECESSARY REPAIRS OR RESEEDINGS WITHIN THE PLANTING SEASON, IF POSSIBLE. AFTER
PERMANENT COVER IS ESTABLISHED.
9.CONSULT CONSERVATION INSPECTOR ON MAINTENANCE TREATMENT.
PLANTING INSTRUCTIONS
PLANTING TECHNIQUES
A.INSURE THAT ROOTS, ONCE REMOVED FROM POT, ARE STRAIGHTENED AND FACE DOWNWARD.
B.CREATE PLANTING AREA FOR EACH PLANT AND EXCAVATE PIT.
C.PLACE PLANTS IN PIT INSURING ROOTS ARE FACING COMPLETELY DOWNWARD.
D.HEEL IN SOIL AROUND PLANT AND PROCEED TO NEXT PLANTING LOCATION.
E.NEWLY PLANTED PLANTS NEED TO BE FASTENED TO THE SUBSTRATE FOR THE ESTABLISHMENT OF NEW ROOTS.
F.ROOTS SHALL BE SPREAD IN THEIR NORMAL POSITION. ALL BROKEN OR FRAYED ROOTS HALL BE CUT OFF CLEANLY.
G.THE DIAMETER OF THE PITS FOR ALL VEGETATIVE STOCK SHALL BE AT LEAST THREE TIMES THE DIAMETER OF THE ROOT MASS.
PLANT PIT WALL SHALL BE SCARIFIED PRIOR TO PLANT INSTALLATION.
H.SET THE PLANTS UPRIGHT, IN THE CENTER OF THE PIT. THE BOTTOM OF THE ROOT MASS SHOULD BE RESTING ON UNDISTURBED
SOIL.
I.PLACE THE BACKFILL AROUND THE BASE AND SIDES OF THE ROOT MASS, AND WORK EACH LAYER TO SETTLE BACKFILL AND TO
ELIMINATE VOIDS AND AIR POCKETS. WHEN PIT IS APPROXIMATELY 2/3 FULL, WATER THOROUGHLY BEFORE PLACING REMAINDER
OF THE BACKFILL. WATER AGAIN AFTER PLACING FINAL LAYER OF BACKFILL.
J.BROKEN OR DAMAGED PARTS WILL BE CUT BACK TO UNDAMAGED TISSUE, LEAVING AS MUCH GREEN BASAL TISSUE AS POSSIBLE
ABOVE THE ROOTS. IF MORE THAN FIFTY PERCENT (50%) OF THE PLANT IS DAMAGED THEN CONTRACTOR SHALL REPLACE THE
PLANT.
CONTAINER STOCK / BARE ROOT
A.STOCK SHALL HAVE BEEN GROWN IN A CONTAINER LONG ENOUGH FOR THE ROOT SYSTEM TO HAVE DEVELOPED SUFFICIENTLY TO
HOLD ITS SOIL TOGETHER ONCE REMOVED FROM THE CONTAINER.
B.CONTAINER PLANTS WILL NEED TO BE WATERED REGULARLY AND PLACED IN SHADY CONDITIONS UNTIL PLANTING OCCURS.
C.BARE ROOT PLANTS ARE FOR IMMEDIATE PLANTING, OTHERWISE SEE D) BELOW.
D.IF BARE ROOTS SPECIMENS ARE NOT TO BE PLANTED WITHIN FOUR (4) DAYS, TEMPORARY HOLDING OF BARE ROOT SPECIMENS
ARE TO BE COVERED ENTIRELY BY A SUITABLE MEDIUM (ETC. SOIL, SAWDUST, MULCH OR THE LIKE) AND WATERED REGULARLY SO
AS TO NOT DRY OUT.
PLANT LOCATIONS
A.NEW PLANTINGS SHALL BE LOCATED WHERE SHOWN ON PLAN EXCEPT WHERE CHANGES HAVE BEEN MADE IN PROPOSED
CONSTRUCTION.
B.NECESSARY ADJUSTMENTS SHALL BE MADE ONLY AFTER APPROVAL BY THE OWNER OR THE OWNER'S REPRESENTATIVE.
WATER
WATER SHALL BE POTABLE AND SHALL NOT CONTAIN ELEMENTS TOXIC TO PLANT LIFE.
