Subject: PTIA SDO Repair Bank Stabilization
rdarling(a)mbakerintl.com has sent you an attachment(s) using Baker eFTP
David & Sue:
Thanks for your response - attached is revised PCN itemizing the stream impacts into 1) culvert
extension /installation (Nationwide Permit 18), 2) rip rap dissipater pad installation (NP 18), and 3)
stabilization /natural channel design (NP 13). Section A.1 b. has been updated to include both NP
13 and NP 18. The Site #3 phase 2 section cannot be limited to natural channel design or bank
stabilization only due to the significant elevation difference here:
For Site #3 Phase 2, a proposed drainage structure (manhole) and outlet pipe
are necessary to address the vertical drop from the existing stormwater pipe
outlet elevation to the existing elevation of the adjacent channel. This existing
vertical drop has eroded (and continues to erode) over time due to the hydraulic
energy released by the water cascading from the perched pipe. In order to
protect the channel from this erosive force, the vertical drop will be contained
within the proposed drainage structure. The outfall pipe will be utilized to direct
Message and contain the flow in its proposed direction. An outfall stabilization pad
Text: constructed of rip -rap is proposed to dissipate remaining energy from the
flow. The stabilization pad will be constructed so that the top elevation of the
rip -rip will coincide with the proposed elevation of the channel bottom.
The temporary and permanent Jordan buffer impacts at Site #3 have also been quantified by
Zone 1 and Zone 2 in the attached PCN and revised Permit Drawings by NP 18 and NP 13.
Thanks again for your prompt and helpful recommendations. Please do not hesitate to contact
me at your convenience should you require any additional information to process this request.

D.
Impact Justification and Mitigation
1.
Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stream impacts are specifically for purposes of stabilization using natural channel design criteria. Buffer impacts are unavoidable due to outfall
locations near stream origins. Existing buffer conditions will be improved by stabilizing currently eroded slopes and re- vegetating.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction - related impacts will be avoided and minimized to the extent possible by applying DEMLR- approved sedimentation and erosion control
protocols as noted on construction plans.
2.

FEATURES AND /OR INSTALLATION OF PROPOSED CHANNEL
SHALL PROGRESS IN AN UPSTREAM MANNER AS INDICATED
ON THE PLAN - BEGINNING WITH CONSTRUCTION OF ZONE 1
AND TERMINATING WITH CONSTRUCTION OF ZONE 3.
2. CONTRACTOR SHALL DEMOLISH THE EXISTING FLUME,
RE -GRADE THE DISTURBED AREA, PLACE NEW RIP -RAP
CHANNEL, AND INSTALL EROSION CONTROL MATTING IN
SEGMENTS OF WORK THAT CAN BE COMPLETED IN ONE
DAY. AT THE END OF EACH WORKDAY, THE NEW RIP -RAP
CHANNEL SHALL BE CONSTRUCTED UP TO THE END OF THE
EXISTING CONCRETE FLUME.
3. CONTRACTOR SHALL SCHEDULE ALL WORK TO BE
PERFORMED DURING DRY WEATHER CONDITIONS AND
COMPLETED BEFORE THE NEXT FORECASTED RAIN EVENT.
WORK ZONES SHOWN ON THE PLAN ARE FOR GENERAL
REFERENCE AND MAY BE ADJUSTED AS NECESSARY WITH
APPROVAL OF THE ENGINEER.
4. GRADED SIDE SLOPES SHALL BE SEEDED, MULCHED AND
STABILIZED USING EXCELCIOR EROSION CONTROL
MATTING.
5. IMPACTS INSIDE THE 50' JORDAN BUFFER = 0.00 s.f., AS THE
WORK IS BEING PERFORMED IS REPLACING AN EXISTING
FACILITY.
6. PIPELINE UTILITIES SHALL BE PROTECTED FROM
CONSTRUCTION TRAFFIC BY USING TIMBER MATTING OR
OTHER METHOD APPROVED BY THE UTILITY COMPANIES.
7. EXCELCIOR EROSION CONTROL MATTING SHALL BE
PLACED ON ALL DISTURBED SLOPE AREAS.
8. ALL DISTURBED AREAS SHALL BE SEEDED AND MULCHED

SEQUENCE NOTES:
GENERAL
THE CONTRACTOR SHALL SUBMIT TO THE ENGINEER AND OWNER A DETAILED CONSTRUCTION PROGRESS SCHEDULE. THESE PLANS
AND SPECIFICATIONS PROVIDE GENERAL CONSTRUCTION SEQUENCE AND SAFETY PARAMETERS WHICH MUST BE INCORPORATED INTO
THE APPROVED SCHEDULE. THE CONTRACTOR'S APPROVED EROSION CONTROL PLAN SHALL BE INCORPORATED INTO THE
CONSTRUCTION SEQUENCE PLAN.
THE CONSTRUCTION OF THE PROJECT MUST BE COMPLETED IN SEQUENTIAL ORDER AS LISTED BELOW:
* MOBILIZATION
* EROSION CONTROL
* CONSTRUCT WORK ELEMENTS
* SEEDING AND MULCHING
PLANNED TEMPORARY EROSION CONTROL FEATURES
1. TEMPORARY CONSTRUCTION ENTRANCE PAD
2. DROP INLET PROTECTION
3. EROSION CONTROL MATTING
ALL DISTURBED AREAS ARE TO BE SEEDED AND MULCHED IN ACCORDANCE WITH ITEMS T -901 AND T -908 OF THE
SPECIFICATIONS, WITHIN 14 DAYS FOLLOWING COMPLETION OF ANY PHASE OF GRADING. PERMANENT GROUND COVER SHALL BE
OBTAINED WITHIN 15 WORK DAYS OR 90 CALENDAR DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION OF THE PROJECT.
ANY FINES, PENALTIES, OR OTHER COSTS ASSESSED BY STATE, LOCAL OR THE GOVERNMENTAL AGENCIES FOR
NON— PERFORMANCE OF THE EROSION CONTROL REQUIREMENTS OF THIS PROJECT AGAINST THE OWNER SHALL BECOME THE
RESPONSIBILITY OF THE CONTRACTOR, AND ANY SUCH ASSESSMENTS, IF NOT PAID BY THE CONTRACTOR, WILL BE DEDUCTED
FROM MONIES DUE AT THE COMPLETION OF THIS PROJECT.

1. ATTEND PRECONSTRUCTION CONFERENCE
2. INSTALL EROSION CONTROL MEASURES
3. PERFORM CONSTRUCTION OPERATIONS
4. SEED AND MULCH ANY DISTURBED AREAS
5. ONCE PERMANENT SEEDING HAS BEEN ESTABLISHED, REMOVE ALL TEMPORARY EROSION CONTROL FEATURES. SEED AND
MULCH THE AREAS EFFECTED BY THE REMOVAL
MAINTENANCE PLAN
1. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY
RUNOFF — PRODUCING RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE
IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. SEDIMENT WILL BE REMOVED FROM BEHIND THE SILT FENCE OR INLET PROTECTION WHEN IT BECOMES ABOUT 0.5 FT.
DEEP. THE EROSION CONTROL BARRIER WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIER.
3. THE ENGINEER MAY DIRECT THAT ADDITIONAL SILT FENCING OR INLET PROTECTION BE INSTALLED AT ANY TIME PRIOR TO
FINAL ACCEPTANCE.
