117. DIRECTIONS TO THE SITE
From USACE Asheville offices (Federal Building): Head west on Patton Ave toward S French Broad Ave (0.4 mi). Keep right at the fork,
follow signs for US-19 N/US-23 N/US-70 W/Wcavcrvillc (0.3 mi). Continue onto I-26 W/US-19 N/US-23 N/US-70 W (1.3 mi). Take exit
25 toward NC-251 (0.3 mi). Turn left onto Broadway St. (0.1 mi). Continue onto Riverside Drive (2.3 mi); the project location is on the left
(currently comprising the combined area of WastePro and Woodfin's Riverside Park).
Location is at/just downstream of French Broad River Mile #143 (Old Leicester Highway Bridge & Woodfin Riverside Park)
18. Nature of Activity (Description of project, include all features)
Project activities include significant modifications to the terrestrial and aquatic environment at Woodfin Riverside Park. The existing park
will be expanded southward to include the current WastePro site, a greenway and other recreational amenities/facilities will be built, and a
standing whitewater wave will be constructed in a portion of the riverbed. Major modifications to the WastePro site elevation will occur to
match grade with the existing park; excavated soils will be hauled offsite. The Park will include river access areas, one at a proposed new
boat ramp, and a second at a beach area adjacent to the Wave feature. A portion of an existing unnamed tributary will be culverted under
the proposed greenway. The Wave will be built using a combination of excavations and fills (boulder installation) to ensure the feature will
work at all flow levels; a bypass channel will allow rivcrgocrs to pass the wave and fish species to migrate up and downstream. Dangerous
historical bridge pilings will also be removed incidental to the project. A comprehensive set of park and wave plans & designs and
according sediment & erosion control sets is attached; these documents comprehensively depict and describe all proposed project work.
19. Project Purpose (Describe the reason or purpose of the project, see instructions)
To celebrate, re -imagine, expand upon, and improve an existing rivcrfront recreational amenity, Woodfin's Riverside Park, with updated
features such as a greenway, park space with expanded facilities, improved river access, and creation of a standing whitewater wave in the
French Broad River. Land -based activities will create amenities for pedestrians, cyclists, whitewater enthusiasts, tourists, and many others;
water -based structures are designed for whitewater paddlers to hone their skills. The wave will have a bypass channel to allow aquatic
organisms to pass up and downstream without engaging with the Wave, and to allow human river users to safely avoid the feature.
Furthermore, it will remove existing wood and metal pilings from the riverbed that currently pose a danger to human safety. Conceptual
design is nearing 90%, and project work is expected to commence in summer 2023; completion date is yet TBD and will hinge upon the
401/404/Section 7 permitting processes, timing of the awarded construction contract, and appropriate meteorological conditions during the
construction window.
USE BLOCKS 20-23 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED
26. Reason(s) for Discharge
Various temporary and permanent discharges of fill material below OHWM are required to construct the wave features in the riverbed and
to sufficiently tie them into either riverbank; there will also be fill placed along the riverbank related to river access (ramp) and shoreline
stabilization (boulder toe protection); one minor discharge is also required to properly span an existing jurisdictional stream on the inland
park area. The wave design dictates permanent discharges in the form of concrete and boulder materials will need to be permanently placed
in and affixed to the riverbed to adequately form the wave feature and conjoined bypass channel. Specific information regarding the
discharges of fill is provided as an Attachment to Block 21b. Some excavation of the riverbed will also be required to construct the wave
feature, although it will be limited due to the presence of bedrock within large portions of the footprint of the wave. Temporary discharges
will be incurred during the placement and adjustment of various coffer dams as necessary to work in the dry and establish wave features.
Construction sequencing is provided in attached Block 20: Supplemental Info as well as in the attached sediment & erosion control plans.

23. Description of Avoidance, Minimization, and Compensation (see instructions)
For the on -land park features, avoidance and minimization to impacts to WOTUS will be achieved through work in the dry and
implementation proper sediment and erosion control techniques during work in and around WOTUS; construction areas will also be
stabilized/replanted with native vegetation to establish a buffer for runoff. For the wave, avoidance and minimization will be primarily
through working in the dry via the establishment of coder dams. Due to minimal impacts to WOTUS, no mitigation is being proposed;
permanent losses are detailed in Block 23 of the attached sheet as well as in the attached detailed sediment and erosion control plans.

24. Is Any Portion of the Work Already Complete? Yes X No IF YES, DESCRIBE THE COMPLETED WORK
Only background studies and limited assessments have been performed to date to understand the feasibility of site designs. A
comprehensive topographical survey of both the land and the riverbed has been conducted. A USACE concurrence request has been granted
acknowledging the presence of WOTUS including the call -out of OHWM elevations. Conceptual planning and design of the inland and
wave features is at approximately 90%, and consultation with the USFWS has begun regarding avoidance/minimization of impacts to both
aquatic and terrestrial listed species known to occur in the corridor containing the project area. Preliminary geotechnical borings have been
conducted to understand subsurface conditions and to assess structural stability. The CLOMR/LOMR process is underway. A mussel survey
conducted in early October detected no endangered mussels; a final endangered species report is expected no later than December 2022.

A volume surface comparison was completed using Autodesk Civil 3D. In order to trim the surfaces to
the correct boundary, the ordinary high water mark (OHWM), had to be determined. Kee Surveying
provided a delineation of the OHWM along the river right bank at the project site along Riverside Park.
S20 used HEC-RAS 2D modeling to run a series of flows through the existing conditions terrain and
matched the Water Surface results to Kee's survey delineation, determining that a flow of 2600cfs
represents ordinary high water. Once the appropriate OHW flow was determined, two different 2D
models were run. One with the existing conditions surface was run at 2600cfs, and another with the
proposed conditions surface was run at 2600cfs. The resulting water surface layers were exported to CAD
as shape files to use as clipping boundaries for volume surface cut/fill comparison, and for areal
comparison of OHW to determine square footage difference.
The table below shows a breakdown of the volume surface comparison completed using the OHWM as a
clipping boundary. The top line is the overall net fill total (3280.38cy), the other three lines are the
quantity of cut or fill for the three different work zones; the wave/bypass, the railroad pier removal, and
the put -in area.

AREA FOR REMOVAL OF INVASIVE SPECIES AND MID -STORY CLEARING
FOR VISIBILITY TO ADHERE TO THE FOLLOWING STEPS:
1. REMOVE INVASIVE PLANTS AND RE-VEGETATE/SEED WITHIN
SHOWN BOUNDARY . DO NOT CLEAR AND GRUB. CLEAR MID -STORY
(2' TO 10' IN HEIGHT) OF ALL VEGETATION, EXCLUDING TREES AND
GROUNDCOVER. BE SURE TO LEAVE GROUND COVER FOR SLOPE
STABILITY.CUT ALL CLIMBING VINES AT 8' OFF THE GROUND AND
REMOVE LOWER PORTION, LEAVING THE PORTION IN THE TREE
CANOPY TO DIE, OR CAREFULLY REMOVE BY HAND WITHOUT
DAMAGING TREE LIMBS.
2. REMOVE INVASIVE PLANTS AROUND THE BASE OF TREE MASSES.
IF USING MECHANICAL EQUIPMENT FOR REMOVAL, RETAIN A 10-20'
BUFFER FROM THE BASE OF ALL TREES THAT WILL REMAIN AFTER
CONSTRUCTION TO AVOID ROOT COMPACTION AND OTHER
DETRIMENTAL IMPACTS TO TREE HEALTH. INVASIVES WITHIN THIS
BUFFER SHOULD BE CONTROLLED BY INTEGRATED PEST
MANAGEMENT TECHNIQUES. IF USING HERBICIDE USE AQUATIC
SAFE HERBICIDE.
3. SEE SPECIFICATIONS FOR ALL SEEDING, PLANTING , SOIL
PREPARATION SPECIFICATIONS AND WATERING INSTRUCTIONS.
CONTRACTOR TO WALK THE AREA WITH THE PROJECT LANDSCAPE
ARCHITECT PRIOR TO REMOVING ANY TREES. IF TREES CUT DOWN
PRIOR TO WALK THROUGH, TREES WILL BE REPLACED BY
CONTRACTOR AT A RATIO OF 3:1 AT A SIZE OF 2 1/2" CALIPER.

All aspects of work shall be
performed in accordance with
all applicable local, state, and
federal regulations pertaining
to worker safety.
r
EROSION CONTROL MEASURE NOTES:
1. THOROUGHLY REVIEW THE SEDIMENT AND EROSION CONTROL PLAN, ADDING EXTRA
PROTECTION ALONG THE RIVER AND NEAR STREAMS (I.E. DOUBLE ROW SILT FENCE).
2. CONTRACTOR TO FINE GRADE AND ADD EROSION CONTROL MATTING AND NATURAL SITE
DEBRIS AT ACCESS AREAS USED BYGEOTECHNICAL ENGINEERS FOR BORING SITES.
3. STABILIZATION MEASURES SHALL BE INITIATED AS SOON AS PRACTICABLE IN PORTIONS OF THE
SITE WHERE CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED, BUT IN
NO CASE MORE THAN SEVEN (7) DAYS AFTER WORK HAS CEASED, EXCEPT AS STATED BELOW.
4. WHERE STABILIZATION BY THE 7TH DAY IS PRECLUDED BY SNOW COVER OR FROZEN GROUND
CONDITIONS STABILIZATION MEASURES MUST BE INITIATED AS SOON AS PRACTICABLE.
5. WHERE CONSTRUCTION ACTIVITY ON A PORTION OF THE SITE IS TEMPORARILY CEASED, AND
EARTH -DISTURBING ACTIVITIES WILL BE RESUMED WITHIN 7 DAYS, TEMPORARY STABILIZATION
MEASURES DO NOT HAVE TO BE INITIATED ON THAT PORTION OF THE SITE.
6. ALL SEDIMENT AND EROSION CONTROL DEVICES SHALL BE INSPECTED ONCE EVERY CALENDAR
WEEK. IF PERIODIC INSPECTION OR OTHER INFORMATION INDICATES THAT A BMP HAS BEEN
INAPPROPRIATELY OR INCORRECTLY INSTALLED, THE PERMITTEE MUST ADDRESS THE
NECESSARY REPLACEMENT OR MODIFICATION REQUIRED TO CORRECT THE BMP WITHIN 48
HOURS OF IDENTIFICATION. IF THIS OCCURS, NOTIFY LANDSCAPE ARCHITECT.
7. PROVIDE SILT FENCE AND/OR OTHER CONTROL DEVICES, AS MAY BE REQUIRED, TO CONTROL
SOIL EROSION DURING UTILITY CONSTRUCTION. ALL DISTURBED AREAS SHALL BE CLEANED,
GRADED, AND STABILIZED WITH GRASSING IMMEDIATELYAFTER THE UTILITY INSTALLATION.
FILL, COVER, AND TEMPORARY SEEDING AT THE END OF EACH DAY ARE RECOMMENDED. IF
WATER IS ENCOUNTERED WHILE TRENCHING, THE WATER SHOULD BE FILTERED TO REMOVE
ANY SEDIMENTS BEFORE BEING PUMPED BACK INTO ANY WATERS OF THE STATE.
8. ALL EROSION CONTROL DEVICES SHALL BE PROPERLY MAINTAINED DURING ALL PHASES OF
CONSTRUCTION UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES AND ALL
DISTURBED AREAS HAVE BEEN STABILIZED. ADDITIONAL CONTROL DEVICES MAYBE REQUIRED
DURING CONSTRUCTION IN ORDER TO CONTROL EROSION AND/OR OFFSITE SEDIMENTATION.
ALL TEMPORARY CONTROL DEVICES SHALL BE REMOVED ONCE CONSTRUCTION IS COMPLETE
AND THE SITE IS STABILIZED.
9. THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF MUD ONTO
PAVED ROADWAY(S) FROM CONSTRUCTION AREAS AND THE GENERATION OF DUST. THE
CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM PAVEMENT, AS MAY BE REQUIRED.
10. TEMPORARY DIVERSION BERMS AND/OR DITCHES WILL BE PROVIDED AS NEEDED DURING
CONSTRUCTION TO PROTECT WORK AREAS FROM UPSLOPE RUNOFF AND/OR TO DIVERT
SEDIMENT -LADEN WATER TO APPROPRIATE TRAPS OR STABLE OUTLETS. THESE TEMPORARY
BERMS AND DITCHES SHALL BE PROTECTED WITH A ROLLED EROSION AND SEDIMENT CONTROL
PRODUCT UNTIL VEGETATION CAN BE ESTABLISHED.
11. ALL WATERS OF THE STATE (WOS), INCLUDING WETLANDS, ARE TO BE FLAGGED OR OTHERWISE
CLEARLY MARKED IN THE FIELD. A DOUBLE ROW OF SILT FENCE IS TO BE INSTALLED IN ALL
AREAS WHERE A 50-FOOT BUFFER CAN'T BE MAINTAINED BETWEEN THE DISTURBED AREA AND
ALL WOS. A 10-FOOT BUFFER SHOULD BE MAINTAINED BETWEEN THE LAST ROW OF SILT FENCE
AND ALL WOS.
12. LITTER, CONSTRUCTION DEBRIS, OILS, FUELS, AND BUILDING PRODUCTS WITH SIGNIFICANT
POTENTIAL FOR IMPACT (SUCH AS STOCKPILES OF FRESHLY TREATED LUMBER) AND
CONSTRUCTION CHEMICALS THAT COULD BE EXPOSED TO STORM WATER MUST BE PREVENTED
FROM BECOMING A POLLUTANT SOURCE IN STORM WATER DISCHARGES.
13. A COPY OF THE INSPECTION RECORDS, AND RAINFALL DATA MUST BE RETAINED AT THE
CONSTRUCTION SITE OR A NEARBY LOCATION EASILY ACCESSIBLE DURING NORMAL BUSINESS
HOURS, FROM THE DATE OF COMMENCEMENT OF CONSTRUCTION ACTIVITIES TO THE DATE
THAT FINAL STABILIZATION IS REACHED.
14. INITIATE STABILIZATION MEASURES ON ANY EXPOSED STEEP SLOPE (3H:1V OR GREATER)
WHERE LAND -DISTURBING ACTIVITIES HAVE PERMANENTLY OR TEMPORARILY CEASED, AND
WILL NOT RESUME FOR A PERIOD OF 7 CALENDAR DAYS.
15. MINIMIZE SOIL COMPACTION AND, UNLESS UNFEASIBLE, PRESERVE TOPSOIL.
16. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM EQUIPMENT AND VEHICLE WASHING, WHEEL
WASH WATER, AND OTHER WASH WATERS. WASH WATERS MUST BE TREATED IN A SEDIMENT
BASIN OR ALTERNATIVE CONTROL THAT PROVIDES EQUIVALENT OR BETTER TREATMENT PRIOR
TO DISCHARGE.
17. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM DEWATERING OF TRENCHES AND EXCAVATED
AREAS. THESE DISCHARGES ARE TO BE ROUTED THROUGH APPROPRIATE BMP'S (SEDIMENT
BASIN, FILTER BAG, ETC).
18. MAINTAIN ALL BUFFER REQUIREMENTS AS INDICATED ON THE PLAN.
19. THE FOLLOWING DISCHARGES FROM SITES ARE PROHIBITED:
19.1. WASTEWATER FROM WASHOUT OF CONCRETE, UNLESS MANAGED BY AN APPROPRIATE
CONTROL;
19.2. WASTEWATER FROM WASHOUT AND CLEANOUT OF STUCCO, PAINT, FORM RELEASE OILS,
CURING COMPOUNDS, AND OTHER CONSTRUCTION MATERIALS;
19.3. FUELS, OILS, OR OTHER POLLUTANTS USED IN VEHICLE AND EQUIPMENT OPERATION AND
MAINTENANCE; AND
19.4. SOAPS OR SOLVENTS USED IN VEHICLE AND EQUIPMENT WASHING.
20. AFTER CONSTRUCTION ACTIVITIES BEGIN, INSPECTIONS ARE EXPECTED TO BE CONDUCTED AT
A MINIMUM OF AT LEAST ONCE EVERY CALENDAR WEEK AND MUST BE CONDUCTED UNTIL FINAL
STABILIZATION IS REACHED ON ALL AREAS OF THE CONSTRUCTION SITE.

1. Sediment traps should not be placed in Waters of the State or USGS blue -line streams (unless
approved by Federal Authorities).
2. Both outlet berm and the stone apron shall have an underlying layer of non -woven geotextile
filter fabric.
3. AU internal side slopes of the sediment trap should be 2.5:1 or flatter.
5. A sediment cleanout stake should be installed and marked to remove sediment at 50% of the
sediment storage volume.
7. After construction of each sediment trap, the area disturbed to construct the trap should be
promptly stabilized, including all side slopes.
8. The following sediment trap requirements shall be maintained:
- Maximum embankment height shall be 5-feet.
- Maximum riprap outlet height shall be 3.5-feet.
- Minimum flow length at top of riprap outlet shall be 5-feet.

INSPECTION AND MAINTENANCE
1. The key to a functional sediment trap is weekly inspections, routine maintenance and regular
sediment removal.
2. Attention to sediment accumulations within the trap is extremely important. Accumulated
sediment deposition should be continually monitored in the trap and removed when
necessary.
3. Remove accumulated sediment when it reaches 50% of the designed
sediment storage volume as marked by the cleanout stake.
4. Removed sediment from the trap shall be placed in stockpile storage areas or spread thinly
across the disturbed area. Stabilize the removed sediment after it is relocated.
5. Regular inspections of sediment traps should be conducted once every calendar week and, as
recommended and within 24-hours after each rainfall event that produces 1/2-inch or more of
precipitation.
6. Disturbed areas resulting from the removal of the sediment trap should be permanently
stabilized and additional BMPs, such as silt fence, should be utilized to handle stormwater
runoff from this disturbed area until final stabilization is reached.

INSTALLATION:
1. STABILIZED CONSTRUCTION ENTRANCES SHOULD BE USED AT ALL POINTS WHERE TRAFFIC WILL
EGRESS/INGRESS A CONSTRUCTION SITE ONTO A PUBLIC ROAD OR ANY IMPERVIOUS SURFACE, SUCH AS
A PARKING LOT.
2. INSTALL A NON -WOVEN GEOTEXTILE FABRIC PRIOR TO PLACING ANY STONE.
3. INSTALL CULVERT PIPE ACROSS THE ENTRANCE WHERE NEEDED TO PROVIDE POSITIVE DRAINAGE.
4. LIMESTONE MAY NOT BE USED FOR THE STONE PAD.
INSPECTION AND MAINTENANCE:
1. INSPECT THE CONSTRUCTION ENTRANCE AT LEAST ONCE PER CALENDAR WEEK. CHECK FOR MUD AND
SEDIMENT BUILDUP AND PAD INTEGRITY. INSPECTIONS MAY BE NEEDED TO BE MORE FREQUENT
DURING LONG PERIODS OF WET WEATHER.
2. THE ENTRANCE SHALL BE MAINTAINED IN A CONDITION THAT WILL PREVENT TRACKING OR FLOWING OF
SEDIMENT ONTO PUBLIC RIGHT-OF-WAYS. THIS MAY REQUIRE TOP DRESSING, REPAIR AND/OR CLEAN
OUT OF ANY MEASURES USED TO TRAP SEDIMENT.
4. WHEN NECESSARY, WHEELS SHALL BE CLEANED PRIOR TO ENTRANCE ONTO PUBLIC RIGHT-OF-WAY,
5. IMMEDIATELY REMOVE ANY MUD OR SEDIMENT TRACKED ONTO ADJACENT IMPERVIOUS SURFACES BY
BRUSHING OR SWEEPING. FLUSHING SHOULD ONLY BE USED WHEN THE WATER IS DIRECTED TOA
SEDIMENT TRAP OR BASIN.
6. REMOVE CONSTRUCTION ENTRANCE ONLY AFTER THE SITE HAS REACHED FINAL STABILIZATION.
PERMANENT VEGETATION SHOULD REPLACE AREAS WHERE THE CONSTRUCTION ENTRANCE HAS BEEN
REMOVED UNLESS THE AREA WILL BE CONVERTED TO AN IMPERVIOUS SURFACE TO SERVE
POST -CONSTRUCTION.

Permanent Stabilization
• Permanent grass seed covered with straw or
other mulches and tackifiers
• Geotextile fabrics such as permanent soil
reinforcement matting
• Hydroseeding
• Shrubs or other permanent plantings covered
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt or
retaining walls
• Rolled erosion control products with grass seed
ILYACRYLAMIDES (PAMS) AND FLOCCULANTS
. Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NC DWR List of Approved PAMS/Flocculants.
Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
Provide ponding area for containment of treated Stormwater before discharging
offsite.
Store flocculants in leak -proof containers that are kept under storm -resistant cover
or surrounded by secondary containment structures.

GENERAL EROSION & SEDIMENT CONTROL NOTES:
(I) THE IMPLEMENTATION OF EROSION AND SEDIMENT CONTROL MEASURES
AND BEST MANAGEMENT PRACTICES INCLUDING CONSTRUCTION,
MAINTENANCE, REPLACEMENT AND UPGRADING ARE THE RESPONSIBILITY OF
THE CONTRACTOR UNTIL ALL CONSTRUCTION IS COMPLETED AND
APPROVED.
(2) THE DETAILS SHOWN ON THIS SHEET ARE AN EXAMPLE OF ACCEPTABLE
METHODS TO USE DURING CONSTRUCTION OF THIS PROJECT. THE
CONTRACTOR IS RESPONSIBLE FOR DEVELOPING AND SUBMITTING A
COFFERDAM PLAN TO INCLUDE SUFFICIENT DETAIL OF MEANS AND
METHODS SATISFACTORILY MEETING THE PROJECT SPECIFICATIONS AND
PERMIT REQUIREMENTS. COFFERDAMS MAY CONSIST OF OTHER METHODS
INCLUDING (BUT NOT LIMITED TO) SECLUSION FENCING, SAND BAGS, BULK
BAGS, SUPER SACKS, SHEET PILE AND INFLATABLE BLADDERS.
COFFERDAMS SHALL INCLUDE PLASTING LINER OR FINE MESH SILT FENCE
TO REDUCE TURBIDITY AND FINES FROM ENTERING THE FREE FLOWING
PORTION OF LIVE WATER.
(5) ALL PUMP INTAKES SHALL BE SCREENED FOR FISH PROTECTION AS
REQUIRED BY REGULATORY AGENCIES.
(4) DEWATERING PUMP DISCHARGE FROM WITHIN COFFERDAM WORK AREAS
SHALL BE RELEASED ONTO FLOODPLAIN AREAS AWAY FROM WETLANDS AND
CONSTRUCTION ACTIVITIES. DISCHARGE SHALL NOT CAUSE EROSION OF
TOPSOIL AND SHALL SHEET FLOW OVER THE FLOODPLAIN BEFORE

WOTUS Impacts Narrative
The Riverside Park and Wave project is a 12.01ac park improvement project that will have impacts to
waters of the United States. There will be both land based and water based impacts including tributary
crossing, the addition and improvements of river access, and the implementation of an in -stream white
water feature (the wave and bypass channel).
Water based impacts will be first in the construction sequencing. Impacts will be both temporary and
permanent. Temporary impacts are necessary to construct the wave and bypass feature as well as bank
tie-ins. These impacts will include a temporary low -flow road, coffer dams and dewatering zones to
allow construction of the wave feature in the dry. The construction of the wave and bypass will be done
in three sections. The project will commence with the lowering of the east bank to gain access for the
wave and bypass construction. Once a temporary construction access is installed down to the east bank
and where the abandoned railroad piles meet the east bank, a temporary low -flow road will be
constructed along the existing remnants of the old railroad crossing. The low -flow road will be
constructed by placing culverts between the abandoned railroad piles and filling over the culverts and
between the piles with cobble. This road will be used to carry construction equipment and material to
the first section of construction, the center of the wave, including the island separating the wave from
the bypass. Once the road is complete, a coffer dam will be constructed surrounding this section on all
sides and it will be dewatered. Once the construction of the first (center) section is complete, the coffer
dam on the upstream side of this section will be relocated to the downstream side of the temporary
low -flow road as well as portions of the upstream side of the road that may not have coffer dam. At this
point, the road should have coffer dam on either side of it. The road will then be removed. While
removing the road, the contractor will also pull out the abandoned bridge pilings. These pilings are to
be removed for the safety of river users. Note, this area of road and piling removal will not be
dewatered, however cofferdams will limit siltation and turbidity migrating downstream. The coffer dams
will be removed as the road gets removed, backing back to the east bank.
The second section of the wave to be constructed will be the east side. This includes from the center of
the wave feature to the east bank tie in and the east bank boulder toe. This section will be surrounded
with coffer dam and dewatered. The portion of coffer dam furthest from the bank will be shifted coffer
dam from the previous section of work, while the portions of coffer dam closer to the bank will be set
from the bank and a built-up peninsula in the footprint of the wave. Once this portion of the wave is
complete, all construction material temporary measures will be removed wrapping up with the coffer
dams.
The third section (fish bypass) will be built from the west bank. Coffer dams will be installed to surround
the limits of work which will be from the island to the west bank tie-in, including boulder toe and bank
stabilization. This section will be dewatered, and construction of the bypass will be done in the dry.
Once construction is complete, all construction equipment and temporary measures will be removed
finishing with the coffer dam.
As part of other water -based impacts, the park improvements include two river access points. The
south access will be constructed first and includes boulder toe/bank stabilization. This section will be
surrounded by a coffer dam and dewatered. The north access will be a precast boat ramp that will be
placed. This will not be done in the dry, however a turbidity curtain will be used to protect the river
from construction activities on the bank.

Land based impacts include a tributary crossing. This crossing will be complete as part of other land -
based activities and will be constructed in the dry using a pump around with dykes. The crossing will be
an elliptical metal culvert that will be partially buried. Once the culvert is installed, the pump around
and temporary dykes will be removed.

EROSION CONTROL MEASURE NOTES:
1. THOROUGHLY REVIEW THE SEDIMENT AND EROSION CONTROL PLAN, ADDING EXTRA
PROTECTION ALONG THE RIVER AND NEAR STREAMS (I.E. DOUBLE ROW SILT FENCE).
2. CONTRACTOR TO FINE GRADE AND ADD EROSION CONTROL MATTING AND NATURAL SITE
DEBRIS AT ACCESS AREAS USED BYGEOTECHNICAL ENGINEERS FOR BORING SITES.
3. STABILIZATION MEASURES SHALL BE INITIATED AS SOON AS PRACTICABLE IN PORTIONS OF THE
SITE WHERE CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED, BUT IN
NO CASE MORE THAN SEVEN (7) DAYS AFTER WORK HAS CEASED, EXCEPT AS STATED BELOW.
4. WHERE STABILIZATION BY THE 7TH DAY IS PRECLUDED BY SNOW COVER OR FROZEN GROUND
CONDITIONS STABILIZATION MEASURES MUST BE INITIATED AS SOON AS PRACTICABLE.
5. WHERE CONSTRUCTION ACTIVITY ON A PORTION OF THE SITE IS TEMPORARILY CEASED, AND
EARTH -DISTURBING ACTIVITIES WILL BE RESUMED WITHIN 7 DAYS, TEMPORARY STABILIZATION
MEASURES DO NOT HAVE TO BE INITIATED ON THAT PORTION OF THE SITE.
6. ALL SEDIMENT AND EROSION CONTROL DEVICES SHALL BE INSPECTED ONCE EVERY CALENDAR
WEEK. IF PERIODIC INSPECTION OR OTHER INFORMATION INDICATES THAT A BMP HAS BEEN
INAPPROPRIATELY OR INCORRECTLY INSTALLED, THE PERMITTEE MUST ADDRESS THE
NECESSARY REPLACEMENT OR MODIFICATION REQUIRED TO CORRECT THE BMP WITHIN 48
HOURS OF IDENTIFICATION. IF THIS OCCURS, NOTIFY LANDSCAPE ARCHITECT.
7. PROVIDE SILT FENCE AND/OR OTHER CONTROL DEVICES, AS MAY BE REQUIRED, TO CONTROL
SOIL EROSION DURING UTILITY CONSTRUCTION. ALL DISTURBED AREAS SHALL BE CLEANED,
GRADED, AND STABILIZED WITH GRASSING IMMEDIATELYAFTER THE UTILITY INSTALLATION.
FILL, COVER, AND TEMPORARY SEEDING AT THE END OF EACH DAY ARE RECOMMENDED. IF
WATER IS ENCOUNTERED WHILE TRENCHING, THE WATER SHOULD BE FILTERED TO REMOVE
ANY SEDIMENTS BEFORE BEING PUMPED BACK INTO ANY WATERS OF THE STATE.
8. ALL EROSION CONTROL DEVICES SHALL BE PROPERLY MAINTAINED DURING ALL PHASES OF
CONSTRUCTION UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES AND ALL
DISTURBED AREAS HAVE BEEN STABILIZED. ADDITIONAL CONTROL DEVICES MAYBE REQUIRED
DURING CONSTRUCTION IN ORDER TO CONTROL EROSION AND/OR OFFSITE SEDIMENTATION.
ALL TEMPORARY CONTROL DEVICES SHALL BE REMOVED ONCE CONSTRUCTION IS COMPLETE
AND THE SITE IS STABILIZED.
9. THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF MUD ONTO
PAVED ROADWAY(S) FROM CONSTRUCTION AREAS AND THE GENERATION OF DUST. THE
CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM PAVEMENT, AS MAY BE REQUIRED.
10. TEMPORARY DIVERSION BERMS AND/OR DITCHES WILL BE PROVIDED AS NEEDED DURING
CONSTRUCTION TO PROTECT WORK AREAS FROM UPSLOPE RUNOFF AND/OR TO DIVERT
SEDIMENT -LADEN WATER TO APPROPRIATE TRAPS OR STABLE OUTLETS. THESE TEMPORARY
BERMS AND DITCHES SHALL BE PROTECTED WITH A ROLLED EROSION AND SEDIMENT CONTROL
PRODUCT UNTIL VEGETATION CAN BE ESTABLISHED.
11. ALL WATERS OF THE STATE (WOS), INCLUDING WETLANDS, ARE TO BE FLAGGED OR OTHERWISE
CLEARLY MARKED IN THE FIELD. A DOUBLE ROW OF SILT FENCE IS TO BE INSTALLED IN ALL
AREAS WHERE A 50-FOOT BUFFER CAN'T BE MAINTAINED BETWEEN THE DISTURBED AREA AND
ALL WOS. A 10-FOOT BUFFER SHOULD BE MAINTAINED BETWEEN THE LAST ROW OF SILT FENCE
AND ALL WOS.
12. LITTER, CONSTRUCTION DEBRIS, OILS, FUELS, AND BUILDING PRODUCTS WITH SIGNIFICANT
POTENTIAL FOR IMPACT (SUCH AS STOCKPILES OF FRESHLY TREATED LUMBER) AND
CONSTRUCTION CHEMICALS THAT COULD BE EXPOSED TO STORM WATER MUST BE PREVENTED
FROM BECOMING A POLLUTANT SOURCE IN STORM WATER DISCHARGES.
13. A COPY OF THE INSPECTION RECORDS, AND RAINFALL DATA MUST BE RETAINED AT THE
CONSTRUCTION SITE OR A NEARBY LOCATION EASILY ACCESSIBLE DURING NORMAL BUSINESS
HOURS, FROM THE DATE OF COMMENCEMENT OF CONSTRUCTION ACTIVITIES TO THE DATE
THAT FINAL STABILIZATION IS REACHED.
14. INITIATE STABILIZATION MEASURES ON ANY EXPOSED STEEP SLOPE (3H:1V OR GREATER)
WHERE LAND -DISTURBING ACTIVITIES HAVE PERMANENTLY OR TEMPORARILY CEASED, AND
WILL NOT RESUME FOR A PERIOD OF 7 CALENDAR DAYS.
15. MINIMIZE SOIL COMPACTION AND, UNLESS UNFEASIBLE, PRESERVE TOPSOIL.
16. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM EQUIPMENT AND VEHICLE WASHING, WHEEL
WASH WATER, AND OTHER WASH WATERS. WASH WATERS MUST BE TREATED IN A SEDIMENT
BASIN OR ALTERNATIVE CONTROL THAT PROVIDES EQUIVALENT OR BETTER TREATMENT PRIOR
TO DISCHARGE.
17. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM DEWATERING OF TRENCHES AND EXCAVATED
AREAS. THESE DISCHARGES ARE TO BE ROUTED THROUGH APPROPRIATE BMP'S (SEDIMENT
BASIN, FILTER BAG, ETC).
18. MAINTAIN ALL BUFFER REQUIREMENTS AS INDICATED ON THE PLAN.
19. THE FOLLOWING DISCHARGES FROM SITES ARE PROHIBITED:
19.1. WASTEWATER FROM WASHOUT OF CONCRETE, UNLESS MANAGED BY AN APPROPRIATE
CONTROL;

1. Sediment traps should not be placed in Waters of the State or USGS blue -line streams (unless
approved by Federal Authorities).
2. Both outlet berm and the stone apron shall have an underlying layer of non -woven geotextile
filter fabric.
3. AU internal side slopes of the sediment trap should be 2.5:1 or flatter.
5. A sediment cleanout stake should be installed and marked to remove sediment at 50% of the
sediment storage volume.
7. After construction of each sediment trap, the area disturbed to construct the trap should be
promptly stabilized, including all side slopes.
8. The following sediment trap requirements shall be maintained:
- Maximum embankment height shall be 5-feet.
- Maximum riprap outlet height shall be 3.5-feet.
- Minimum flow length at top of riprap outlet shall be 5-feet.

RIP -RAP STABILIZATION
1. The key to a functional sediment trap is weekly inspections, routine maintenance and regular
sediment removal.
2. Attention to sediment accumulations within the trap is extremely important. Accumulated
sediment deposition should be continually monitored in the trap and removed when
necessary.
3. Remove accumulated sediment when it reaches 50% of the designed
sediment storage volume as marked by the cleanout stake.
4. Removed sediment from the trap shall be placed in stockpile storage areas or spread thinly
across the disturbed area. Stabilize the removed sediment after it is relocated.
5. Regular inspections of sediment traps should be conducted once every calendar week and, as
recommended and within 24-hours after each rainfall event that produces 1/2-inch or more of
precipitation.
6. Disturbed areas resulting from the removal of the sediment trap should be permanently
stabilized and additional BMPs, such as silt fence, should be utilized to handle stormwater
runoff from this disturbed area until final stabilization is reached.

INSTALLATION:
1. STABILIZED CONSTRUCTION ENTRANCES SHOULD BE USED AT ALL POINTS WHERE TRAFFIC WILL
EGRESS/INGRESS A CONSTRUCTION SITE ONTO A PUBLIC ROAD OR ANY IMPERVIOUS SURFACE, SUCH AS
A PARKING LOT.
2. INSTALL A NON -WOVEN GEOTEXTILE FABRIC PRIOR TO PLACING ANY STONE.
3. INSTALL CULVERT PIPE ACROSS THE ENTRANCE WHERE NEEDED TO PROVIDE POSITIVE DRAINAGE.
4. LIMESTONE MAY NOT BE USED FOR THE STONE PAD.
INSPECTION AND MAINTENANCE:
1. INSPECT THE CONSTRUCTION ENTRANCE AT LEAST ONCE PER CALENDAR WEEK. CHECK FOR MUD AND
SEDIMENT BUILDUP AND PAD INTEGRITY. INSPECTIONS MAY BE NEEDED TO BE MORE FREQUENT
DURING LONG PERIODS OF WET WEATHER.
2. THE ENTRANCE SHALL BE MAINTAINED IN A CONDITION THAT WILL PREVENT TRACKING OR FLOWING OF
SEDIMENT ONTO PUBLIC RIGHT-OF-WAYS. THIS MAY REQUIRE TOP DRESSING, REPAIR AND/OR CLEAN
OUT OF ANY MEASURES USED TO TRAP SEDIMENT.
4. WHEN NECESSARY, WHEELS SHALL BE CLEANED PRIOR TO ENTRANCE ONTO PUBLIC RIGHT-OF-WAY,
5. IMMEDIATELY REMOVE ANY MUD OR SEDIMENT TRACKED ONTO ADJACENT IMPERVIOUS SURFACES BY
BRUSHING OR SWEEPING. FLUSHING SHOULD ONLY BE USED WHEN THE WATER IS DIRECTED TOA
SEDIMENT TRAP OR BASIN.
6. REMOVE CONSTRUCTION ENTRANCE ONLY AFTER THE SITE HAS REACHED FINAL STABILIZATION.
PERMANENT VEGETATION SHOULD REPLACE AREAS WHERE THE CONSTRUCTION ENTRANCE HAS BEEN
REMOVED UNLESS THE AREA WILL BE CONVERTED TO AN IMPERVIOUS SURFACE TO SERVE
POST -CONSTRUCTION.

GENERAL EROSION & SEDIMENT CONTROL NOTES:
(I) THE IMPLEMENTATION OF EROSION AND SEDIMENT CONTROL MEASURES
AND BEST MANAGEMENT PRACTICES INCLUDING CONSTRUCTION,
MAINTENANCE, REPLACEMENT AND UPGRADING ARE THE RESPONSIBILITY OF
THE CONTRACTOR UNTIL ALL CONSTRUCTION IS COMPLETED AND
APPROVED.
(2) THE DETAILS SHOWN ON THIS SHEET ARE AN EXAMPLE OF ACCEPTABLE
METHODS TO USE DURING CONSTRUCTION OF THIS PROJECT. THE
CONTRACTOR IS RESPONSIBLE FOR DEVELOPING AND SUBMITTING A
COFFERDAM PLAN TO INCLUDE SUFFICIENT DETAIL OF MEANS AND
METHODS SATISFACTORILY MEETING THE PROJECT SPECIFICATIONS AND
PERMIT REQUIREMENTS. COFFERDAMS MAY CONSIST OF OTHER METHODS
INCLUDING (BUT NOT LIMITED TO) SECLUSION FENCING, SAND BAGS, BULK
BAGS, SUPER SACKS, SHEET PILE AND INFLATABLE BLADDERS.
COFFERDAMS SHALL INCLUDE PLASTING LINER OR FINE MESH SILT FENCE
TO REDUCE TURBIDITY AND FINES FROM ENTERING THE FREE FLOWING
PORTION OF LIVE WATER.
(5) ALL PUMP INTAKES SHALL BE SCREENED FOR FISH PROTECTION AS
REQUIRED BY REGULATORY AGENCIES.
(4) DEWATERING PUMP DISCHARGE FROM WITHIN COFFERDAM WORK AREAS
SHALL BE RELEASED ONTO FLOODPLAIN AREAS AWAY FROM WETLANDS AND
CONSTRUCTION ACTIVITIES. DISCHARGE SHALL NOT CAUSE EROSION OF
TOPSOIL AND SHALL SHEET FLOW OVER THE FLOODPLAIN BEFORE
RETURNING TO LIVE WATER DOWNSTREAM OF THE WORK AREA. ALL
RETURN FLOWS MUST MEET PERMIT REQUIREMENTS FOR TURBIDITY.
(5) ALL EARTHWORK AND WOOD STRUCTURES CONSTRUCTION WITHIN THE
ORDINARY HIGH CHANNEL SHALL CONFORM TO WATER QUALITY STANDARDS
