Hi Sue,
Please see attached our updated drawings as well as a NC Buffer Exhibit for your review. A list of your comments from
December 16, 2021, and our responses, are included below.
1. Would you please provide a buffer/wetland impact plan sheet that clearly documents how you calculated the
buffer impacts (and where you indicate buffer and wetland overlap). I recommend using different colors to identify
different areas and/or overlapping areas. I see the wetland lines on the plan sheets but it's really hard to tell what
is existing lawn, what is existing "forested" buffer, where there are wetland impacts and buffer impacts etc.
A buffer impacts exhibit is included with this submission and should explain the impacts, buffers and other
overlapping areas.
2. Are you proposing to dewater the entire length of stream channel and do all the instream work at once, or dewater
each structure location individually? I just want to be sure we capture the temporary impacts correctly. If you are
only proposing to dewater each structure location individually then the temporary check dam shown at the bottom
of the project would be a concern for DWR. We don't allow temporary sediment control measures "in channel".
Dewatering will be done at each structure location individually. We have removed the temporary check dam.
3. On the plans there's a line identified as "tree line to be removed" and it looks like that area is proposed to be
replanted as lawn. Since this would be in the buffer area, could you explain this further for me please.
4. On the plans there's a statement to only clear necessary trees within LOD. Can you please provide a definition of
"necessary", or better yet, update the plans to include that explanation? The construction crew may have a very
different definition of "necessary" than you or I, and since it's in the buffer area I want to be sure we are all on the
same page.
5. Can you provide some assurance that the landowners understand that the impacts to the buffer are temporary
and they must allow natural regeneration in all locations were trees were present (with the exception of the
maintained sewer corridor). We've seen many projects like this where landowners are happy to have new lawn
and permanently maintain it like that when the permittee stated the impacts would be temporary. I recommend
that the City propose temporary "no mow/maintenance" signs in all areas they are proposing as temporary buffer
impacts at least for the first few years while natural regeneration and/or live stakes are small.
In response to comments 3 to 5: We have adjusted the notes and the drawing to show the existing riparian buffer
area to be reestablished as a buffer and replanted with trees. Existing lawn areas (at 12 Devonshire Drive within
the LOD up to the tree line and within the fence relocations at 10 Devonshire Drive, 2006 and 2008 Downing
Street). No mowing will be allowed within the riparian buffer. The City monitors stream buffer impacts across the
1

City for non -City constructed projects and will ensure these impacts will return back to existing conditions. See
updated planting plan sheet (C-3) or buffer exhibit for different planting areas.
Let us know if you have any additional questions.
Thanks,
Amanda Weikmann PE

Hi Amanda,
I have reviewed this project and have a couple questions.
• Would you please provide a buffer/wetland impact plan sheet that clearly documents how you calculated the
buffer impacts (and where you indicate buffer and wetland overlap). I recommend using different colors to
identify different areas and/or overlapping areas. I see the wetland lines on the plan sheets but it's really hard
to tell what is existing lawn, what is existing "forested" buffer, where there are wetland impacts and buffer
impacts etc.
• Are you proposing to dewater the entire length of stream channel and do all the instream work at once, or
dewater each structure location individually? I just want to be sure we capture the temporary impacts
correctly. If you are only proposing to dewater each structure location individually then the temporary check
dam shown at the bottom of the project would be a concern for DWR. We don't allow temporary sediment
control measures "in channel".
• On the plans there's a line identified as "tree line to be removed" and it looks like that area is proposed to be
replanted as lawn. Since this would be in the buffer area, could you explain this further for me please.
• On the plans there's a statement to only clear necessary trees within LOD. Can you please provide a definition
of "necessary", or better yet, update the plans to include that explanation? The construction crew may have a
very different definition of "necessary" than you or I, and since it's in the buffer area I want to be sure we are all
on the same page.
• Can you provide some assurance that the landowners understand that the impacts to the buffer are temporary
and they must allow natural regeneration in all locations were trees were present (with the exception of the
maintained sewer corridor). We've seen many projects like this where landowners are happy to have new lawn
and permanently maintain it like that when the permittee stated the impacts would be temporary. I
recommend that the City propose temporary "no mow/maintenance" signs in all areas they are proposing as
temporary buffer impacts at least for the first few years while natural regeneration and/or live stakes are small.
I will consider the application on hold until receipt of responses to the above information. Please let me know if you
have any questions,
Thanks.

DEFINITION.' GRAVELED AREA TO BE LOCATED AT POINTS WHERE VEHICLES ENTER AND LEAVE A CONSTRUCTION SITE.
PURPOSE' TO PROVIDE A BUFFER AREA WHERE VEHICLES CAN DROP THEIR MUD AND SEDIMENT TO AVOID TRANSPORTING IT ONTO PUBLIC
ROADS, TO CONTROL EROSION FROM SURFACE RUNOFF, AND TO HELP CONTROL DUST.
CONDITIONS: TO BE USED WHEREVER TRAFFIC WILL BE LEAVING A CONSTRUCTION SITE AND MOVING DIRECTLY ONTO A PUBLIC ROAD OR
OTHER PAVED OFF -SITE AREA. CONSTRUCTION PLANS SHOULD LIMIT TRAFFIC TO PROPERLY CONSTRUCTED ENTRANCES.
DESIGN
CRITERIA: AGGREGATE SIZE - USE "CLASS A" STONE, WITH GEO-TEXTILE LINER.
DIMENSIONS OF GRAVEL PAD - THICKNESS = 8" MINIMUM
WIDTH = 12' MINIMUM OF FULL WIDTH AT ALL POINTS OF THE VEHICULAR ENTRANCE
AND EXIT AREA, WHICHEVER IS GREATER
LENGTH = 25' MINIMUM WITH GEO-TEXTILE LINER
LOCATION = LOCATE CONSTRUCTION ENTRANCES AND EXITS TO LIMIT SEDIMENT FROM
LEAVING THE SITE AND TO PROVIDE FOR MAXIMUM UTILITY BY ALL CONSTRUC-
TION VEHICLES. AVOID STEEP GRADES AND ENTRANCES AT CURVES IN PUBLIC
ROADS.
SITE CONDITIONS MAY REQUIRE VARIATIONS FROM THESE DESIGN CRITERIA. VARIATIONS WILL BE DETERMINED OR APPROVED
BY THE APPROPRIATE CITY EROSION CONTROL AUTHORITY.
