2. Project Overview
·This project is in Division 5, and design will be managed by the Central Project Delivery Team.
·ROW date scheduled for September 2018. LET date scheduled for September 2019.
3. Review of Preliminary 4B Permit Drawings
·The permit drawings were produced for the 4C meeting to help generate discussion and give a
better view of potential impact areas and modifications to the drainage design.
·Sheet 4 (Site 1) – Repairing scour hole and extending pipe systems to eliminate large scour hole.
o Allowable impacts are needed at pipe outlets on left and right sides of existing culvert.
Permanent and temporary impacts are needed for scour hole stabilization.
o No comments were made regarding the permit drawings at Site 1.
·Sheet 5 (Site 2A) – Replacing and repairing existing rip rap outlet into jurisdictional stream SD.
o Scour hole stabilization requires permanent and temporary stream impacts and buffer
zone 1 impacts.
o No comments were made regarding the permit impacts at Site 2A.
·Sheet 5 (Site 2B) – Channel improvements for stream SD where 3@10’x10’ RCBC culvert
extension work is proposed.
o Comments during the meeting indicate to place additional rip rap on the west and east
side of stream SD where it confluences with Stirrup Iron Creek. Site visit was done to
determine need for riprap bank stabiliztion and west side was stable with riprap, but
east will need additional riprap to armor the graded area of transition.
o Additional permanent and temporary stream impacts on stream SD will be required due
to bank stabilization on east bank. Additional buffer impacts for west bank
construction access will not be needed as mentioned in the meeting since west bank
is stable.
·Sheet 5 (Site 3A) – Extending existing 3 @ 10’ x 10’ RCBC conveying a FEMA stream (Stirrup
Iron Creek)
o No comments were made regarding the permit impacts at Site 3A and 3C.
o Allowable and mitigable buffer impacts at culvert construction and along fill slope.
·Sheet 5 (Site 3B) – Cleaning out and adding rip rap to pipe outlet over wetland WI
o Wetland will be total take.
o No comments were made regarding the permit impacts for Site 3B.
o Separate clarity comment across Stirrup Iron Creek on side tributary from existing 36”
pipe was mentioned. Line style for converging ditch needs to be called out as “Non-
JS” and top of banks removed.
·Sheet 6 (Site 4) – Cut slope impact for erosion control measures to construct headwall on existing
pipe.
o 10 feet of mechanized clearing in wetland from slope stakes.
o No comments on this site
·Sheet 6 (Site 4B, old site 4A from 4B meeting) – Storm water systems to outlet in stream SF
designated as a JS with no buffers.
o Jurisdictional feature begins 47 feet from confluence with Brier Creek. Measurement
taken from NRTR table.
o Recommend extending JS line to temporary stream impacts and change line styles and
top of bank to start of JS.
o No comments provided on the permanent, temporary, and buffer impacts
·Sheet 6 (Site 5A) – Replacing existing 30” CMP
o Stream impacts in Brier Creek from embankment protection.
o Add additional 10 ft of allowable buffer impacts on the north side of the proposed 42”
RCP.

·Sheet 6 (Site 5B -Removed after 4B meeting) – Proposed tail ditch to run from proposed storm
water system to stream bank
o Removed due to design change. Piped to JB at Site 5A.
·Sheet 7 (Site 5C) – Culvert extension of 12’x12’ RCBC
o Extend outlet rip rap on west bank to bend and increase permanent and temporary
impacts.
·Sheet 7 (Site 5D) – Existing scour hole at pipe outlet. Location is in the bend of Brier Creek just
upstream of the 1@ 12’ x 6’ RCBC entrance.
o Extend ETF line from existing wingwall up to edge of fill slope.
o Add buffer impacts around Site 5D to edge of stream impacts and new ETF line.
·Sheet 7 (Site 5E) – New 1@ 12’ x 10’ RCBC buried 1ft
o Extend proposed riprap to edge of ROW and eliminate temporary stream impacts on
upstream side of new RCBC. No temporary stream impacts necessary outside of
ROW on upstream side. Leave downstream riprap and temporary stream impacts as
is since all within ROW.
o Questionable ditch and wetland tie in location, east of proposed culvert. Tie in point
will be addressed in the field
o Since 5E stream impacts are greater than 150 LF, buffer impacts will change from
allowable to mitigable.
·Sheet 7 (Site 6) – Stream SA impacted by fill slope and concentrated flow from pipe outlet
o Site 6 initially left off permit drawings prior to 4C meeting since rip rap was far enough
away from JS feature.
o Site 6 to be added to permit drawings. Rip rap outlet protection to be extended 10’ into
the JS line generating permanent and temporary impacts.
·Sheet 7 (Site 7) – Stream SB impacted by adding Class 1 rip rap at stream confluence with Brier
Creek.
o Site 7 initially left off permit drawings prior to 4C meeting since 4B meeting called for
Site 7 to be incorporated into Site 5C.
o Site 7 to be reinstated with permanent impacts and temporary impacts to PDE line.
·Sheet 7 (Site 8A) – Proposed -Y3- covers existing stream SH
o No comments on this site
·Sheet 7 & 14 (Site 8B) – Partial take of wetlands, and rerouting wetland outlet to Brier Creek
o Ditch’s elevation must not drain wetland. Tie in point will be addressed in the field.
o Permit drawing impacts are fine in this location, no comments.
·Sheet 10 (Site 9) – Stream grading to tie into proposed and existing pipe entrance of JS SE.
o Anticipate bore pit will tear up concrete swale. Extend existing rip rap to proposed
headwall.
o Add blind junction box 12 ft into slope from pipe inlet to allow contractor enough
room to match inlet elevation.
·Sheet 11 (Site 10) – Separated sites into 10A, 10B, and 10C
o Culvert extension and channel improvements impact stream SJ (Site 10A), wetland
WK (Site 10B), and wetland WN (Site 10C).
o Buffer impacts for construction access and construction of culvert extension.
o Fill slope might add additional impacts (mechanized clearing)
o to wetland WN.
o Buffer impacts to be extended to extent of wetland WK impacts.
o Make sure I-5506 drainage plans are gray and add additional drainage by other notes to
clarify separate project.
·Sheet 12 (Site 11) – Tying 51” W x 57”H CMP to a proposed junction box and extending with
60” RCP
o No comments on either stream impacts or buffer impacts.

·Sheet 12 (Site 11A) – Grade stream to tie into both the proposed and existing pipe entrance.
o Add buffer impacts on left bank.
o Add blind junction box 12 ft into slope from pipe inlet to allow contractor enough
room to match inlet elevation.
o Check old project and add note to summary sheet with allowable impacts from prior
project. Mitigated previously under I-5506.
·Sheet 12 (Site 12) – Temporary stream impacts on I-5506 JS due to permanent impacts on
upstream SG.
o Coordinate with I-5506 staff and add note to summary sheet with allowable impacts
from prior project. Mitigated previously under I-5506.
