Amanda,
Attached is the additional information you requested for the area around impact location 13. Please let me
know if you have any additional questions about the permit modification request. I will call to discuss this
week.
Zan,
Do you want to meet on site sometime for a compliance site visit?
Thank you,

29/3 Permit Modification Request
SAW -2017-00488, DWR# 05-1950 V2
Amanda:
On July 6th 2018 Atlas Environmental staff conducted a site visit to determine if impacts
had taken place at the stream end point upstream of the arched culvert, referenced as
#13, on the impact map. Geospatial analysis has indicated that the stream layer on the
impact map was skewed by approximately 38 feet to the West. This distance was
measured by overlaying the AutoCAD map with winter/fall aerial imagery. Included
with this response are two maps used to make the deremination showing overlays with
the site plan and aerial imagery. The end point on the impact map also does not align
with LiDAR or topographic layers. On the aerial imagery the tops of the culverts are
clear and directly align with GPS points collected by Atlas. After consulting with the
project engineer that we meet on site, John Kinnaird, he assures that they were well
above the flag representing the endpoint that was field verified during the
JD/permitting process in 2017.
In addition to the GIS analysis Atlas compared photographs from the most recent site
visit to the ones from delineation field work in 2016 and believes to have located the
same trees. In both photographs a large tulip poplar is directly adjacent to a smaller
tree that appears to be a birch. Despite the photos being taken from a different aspect
the trees appear to be the same relative size and location in both photographs. In the
2018 photograph the tree is broken off and is a likely reason for not being able to
locate the flagged end point. In addition there are few large tulip poplars in the vicinity
of area #13 on the impact map.

We believe due to the current hydrology and evidence of long established flow
combined with the geospatial analysis and vegetation comparisons that the stream has
not been impacted by the constructed driveway.
