Hi All,
I needed a little time to finalize and pull this together in response to Steve's prior email comment regarding
proposed wetland reestablishment: "Did not realize additional investigation was being done on the re-
establishment area, can you give me a brief update on the boring results and how you anticipate it changing
the draft being reviewed (design, credit, etc)? If anything substantial, I would like to update the IRT in their
review of the draft or at least provide them the supplemental info."
Attached are:
(1) a revised plan Sheet 0.2.2. showing wetland approaches, including the reestablishment area and proposed
grading - grading has been refined based on LSS study, LSS boring locations have been added and the
reestablishment limits have been adjusted, however only slightly. Numbers report in table on this sheet reflect
the updated acreage.
(2) LSS report including 2 figures- (1) a photograph of the valley showing in landscape section the high area
believed to be an old road, and (2) a map showing the borings and data on hydric soil indicators and depths.
Let me know if you all have any questions about this new data. I believe this new information to be consistent
in support of the earlier Wildlands in-house findings and summary in the mitigation plan. We did reduce the
grading depths based on this new data, probably by about 6" on average if I had to estimate. The grading in
the footprint of the old road bed is still rather significant, but is supported by the obvious consistency of this
manipulated landform and the buried A horizon at depths supporting the removal of placed overburden. We
have looked back at aerials- the road bed feature is visible 40-50 years back. Aerials prior to that are a bit
grainy to interpret that well.
Thanks,
Jake

Thanks Jake, but I'll print them out next time I'm in the office. I copied Erin, Mac and Kim to see if they wanted hard
copies mailed to them or just plan to print their own, since it is only two pages.

Thanks for your efforts Steve. Computing away myself this evening, and I apologize that those didn't make it
into the package. See attached. Let me know if we can forward on hard copies of these for you as well and, if
so, where we ought to send.
best,
Jake

Actually, while trying to work out some questions with the real estate package, I noticed that my hard copy and the
digital copy seem to be missing figures 10 & 11. Unless they are elsewhere in the package that I haven't found, email
them to me so that I can get them to the IRT for review.

Jake,
I had trouble downloading the large plan file and thought it finally worked without network issues, but later when trying
to review it turned out to be an issue and I was unable to open. Luckily, Kim uploaded the cd she received and I was able
to access that. I did a quick review for completeness and recently put it out to the IRT. Their comments are due back to
me Friday, May 29tn
Did not realize additional investigation was being done on the re-establishment area, can you give me a brief update on
the boring results and how you anticipate it changing the draft being reviewed (design, credit, etc)? If anything
substantial, I would like to update the IRT in their review of the draft or at least provide them the supplemental info.
We are managing the homeschool and workjuggling act like everyone else, but sometimes makes for long days.
Definitely all looking forward to a little more time out of the house and the kids being able to socialize. Have not done a
good job of incorporating the soccer drills into the routine yet, especially with little brother trying to join, but plan to
work on it more. I'm definitely missing my games as an exercise outlet!

Steve,
Andrea said you were able to get access the files no problem. I just wanted to check in and make sure the
package was looking complete and no major concerns/questions thus far.
FYI- We've completed our boring study in the proposed reestablishment wetland and working on tweaking our
plans to incorporate the findings. We were planning to incorporate along with comments into the final mit.
plan, but let me know if you'd like to see a preview of this once we've gotten our design adjustments
tightened up.

Hope all is well for you guys and looking forward to some pickup later this summer. Those are some good
drills that Hasani has been sending, although I think I'm getting more out of them than Evie... fairly advanced
some of them. I'm going to keep pushing her to try them- she's having a mental block with anything that
doesn't come easy.
Thanks,
Jake

INTRODUCTION
Soil & Environmental Consultants, PA (S&EC, PA) was retained to perform an evaluation to assess the
presence and extent of hydric soils onsite. The evaluation area is within a maintained pasture. The
evaluation area contained hydric soil indicator F3 (Depleted matrix) throughout the majority of its
extent (see attached Hydric Soils Investigation Map). An area that appears to be an old road bed bisects
the hydric soil polygon and contained soils with a buried A horizon that, in its condition prior to
construction of the road, would have met the F3 (depleted matrix) hydric soil indicator.
METHODOLOGY
On March 261", 2020 S&EC, PA staff performed a hydric soil evaluation at the site. Hand auger borings
were advanced on the property at locations appropriate to approximately estimate the location and
extent of hydric soils within the project area (see attached Hydric Soils Investigation Map). Each soil
boring was evaluated to assess the presence or absence of hydric soil indicators. Hydric soil indicators
were identified utilizing the NRCS Field Indicators of Hydric Soils in the United States - A Guide for
Identifying and Delineating Hydric Soils (Version 8.2, 2018).
The evaluated area is mapped as the well -drained Spivey-Whiteoak soil series complex (Loamy -skeletal,
isotic, mesic Typic Humudepts & Fine -loamy, isotic, mesic Humic Dystrudepts, respectively). Most hydric
soils observed onsite within the project area were most like the Hatboro or Holly soil series (Fine -loamy,
mixed, active, nonacid, mesic Fluvaquentic Endoaquepts)
RESULTS
Approximately 12 soil borings were performed within the study area. Soil characteristics were evaluated
and all areas identified as containing hydric soils met the hydric soil criteria described below. Borings B1,
B7 and B9 were not hydric soils and did not contain a buried A horizon.
Soil borings were performed within the area approximately indicated on the attached Hydric Soils
Investigation Map. Hydric soil areas had a depleted matrix (F3 indicator) within 7" of the current land
surface.
Indicator F3: Depleted Matrix
Technical Description: A layer that has a depleted matrix with 60 percent or more chroma of 2
or less and that has a minimum thickness of either:
(a) 2 in. (5 cm) if the 2 in. (5 cm) is entirely within the upper 6 in. (15 cm) of the soil, or
(b) 6 in. (15 cm) starting within 10 in. (25 cm) of the soil surface.
An area bisects the hydric soils area that contains a layer of soil that is believed to have been deposited
when an old road was constructed. Areas where the buried A horizon was found below 10" of existing
land surface were not included in the hydric soil area but are defined on the Hydric Soils Investigation
Map (Borings B3 and 66). A general cross section of the landscape that indicates where hydric soils
were found in relation to the buried hydric soils is shown in the attached photograph.
