Re: 3:45-Acre La Camera Parkway Property
Karat Feature Evaluation

Dear Mr. Berlanga:

Please ?nd enclosed a Karst Feature Evaluation report, which summarizes our ?ndings on the i45-
acre above-referenced property. Thank you for the opportunity to provide to you our environmental
services.

The Karat Feature Evaluation has been performed under the supervision ofa biologist holding a U.S.
Fish and Wildlife Service (USFWS) Section 10(a)l(A) permit for research and recovery of
threatened and endangered species and a licensed Professional Geoscientist. Based on the guidelines
set forth by the Texas Parks and Wildlife Department (TPWD) and USFWS, the karst feature in
question, 8-17, does not appear to contain potential habitat for listed karst invertebrates. All
conclusions, opinions, and recommendations in this report are based upon site conditions at the time
of Paps-Dawson's site visit and should not be relied upon to represent conditions at later dates.

If you have questions about the report or we may provide further services, please do not hesitate to
contact our office.

Sincerely,
Pepe-Dawson Engineers, Inc.

Karst Feature Evaluation

INTRODUCTION
Pape-Dawson Engineers, Inc. was contracted to conduct a karst feature evaluation on one feature
(S-17) identified by others as potential habitat for listed karst invertebrates on a ±45-acre property
located north of La Cantera Parkway and west of Interstate-10 in northern Bexar County (Exhibit
1).
KARST INVERTEBRATE BACKGROUND & SITE INFORMATION
In 2000, the USFWS listed nine karst invertebrates in Bexar County (USFWS 2000). These species
are obligate cave dwellers, spending their entire lives in caves and other void spaces in limestone
rock. They consist of two un-named beetles, Rhadine infernalis and Rhadine exilis, the Helotes
mold beetle (Batrisodes venyivi), Madla’s Cave meshweaver (Cicurina madla), Government
Canyon Bat Cave meshweaver (Cicurina vespera), Robber Baron Cave meshweaver (Cicurina
baronia), Braken Bat Cave meshweaver (Cicurina venii), Government Canyon Bat Cave spider
(Neoleptoneta microps), and Cokendolpher Cave harvestman (Texella cokendolpheri).
In a report prepared for the USFWS and Texas Parks and Wildlife Department (TPWD), Veni and
Associates (2003) delineated five areas in the Bexar County region reflecting the likelihood of
finding federally endangered karst invertebrate species. The subject site is located entirely within
designated karst zone 2. Karst zone 2 is defined areas with high probability of containing suitable
habitat for endangered karst invertebrate species (Exhibit 2). Karst zone 2 requires a karst terrain
feature survey be conducted by a karst geologist or karst biologist with demonstrated experience
identifying karst features (USFWS 2015).
In addition to the karst zones, six karst fauna regions (KFR) have been delineated within Bexar
County (Veni 1994, Veni and Associates 2003), including: Stone Oak, University of Texas at San
Antonio, Helotes, Government Canyon, Culebra Anticline, and Alamo Heights. The subject site is
not located within a KFR (Exhibit 2).
The closest designated critical habitat for karst invertebrates is critical habitat units (CHU) 23 and
9 (USFWS 2012, Exhibit 2). CHU 23 is located approximately one mile northwest of the subject
site and has been delineated for the protection of Rhadine infernalis. CHU 9 is located
approximately one mile south of the site and has been delineated for the protection of Cicurina
madla. The project site is not designated by the USFWS as critical habitat for any of the
endangered karst invertebrates (USFWS 2003, Exhibit 2).
PROPERTY DESCRIPTION
Topography
Elevation across the site ranges from approximately 1,110 feet to 1,258 feet above mean sea level.
Surface runoff generally flows southeast to Leon Creek (Exhibit 3).

Karst Feature Evaluation

Geology
The site is located within the Balcones Fault Zone (BFZ). The BFZ consists of southwestward
trending high angle, normal faults with varying degrees of displacement. The BFZ divides the
relatively horizontal Cretaceous-age rocks of the Edwards Plateau from the southeast dipping
Tertiary-age units of the Gulf Coastal Plane. According to published geologic maps and reports by
SWCA (2001) and Bowman Engineers (2016), the site is located in the basal nodular (Kekbn) and
dolomitic (Kekd) members of the Kainer formation (Kek) (Stein and Ozuna, 1995, Exhibit 4).
The basal nodular (Kekbn) member is characterized as massive, shaly, mudstone to grainstone,
nodular limestone. Karst development in the Kekbn is characterized by vertical shafts as well as
large lateral caves. The dolomitic (Kekd) member is characterized as massively bedded, mudstone
to grainstone, crystalline limestone. Karst development in the Kekd is characterized by small
sinkholes and often caves develop as vertical shafts.
METHODS
A geologic assessment was performed in accordance with the Texas Commission on
Environmental Quality (TCEQ) by others in 2001 and 2016 (SWCA 2001, Bowman 2016).
Features are discovered by walking 50-foot transects throughout the property. While this
accomplishes the discovery of many visible features, hindrances such as dense vegetation, lighting,
topographic relief, soil cover, brush piles, etc. may conceal features. The results Bowman study
identified one feature that had the potential to be the surface expression of karst invertebrate
habitat. A karst geologist and permitted karst biologist familiar with habitat requirements for karst
invertebrates re-evaluated this feature, S-17 on September 21 and 29 and October 5, 2016, totaling
approximately 13 man-hours.
A habitat assessment produced by Bowman Engineers describes feature S-17 as “One feature that
was visually observed in the field and contained multiple small openings along its surface exposed
reach. The entrance to the feature contained troglophitic species, which are an indicator that the
feature supports habitats necessary for listed karst species (i.e. food source). The area surrounding
the entrance to the feature and extending to the surface exposed fault is depressional in nature,
which can sometimes suggest prior collapse of subsurface voids. The size of the depressional area,
connectivity to an exposed fault, geologic formation, and presence of troglophitic species at the
entrance and known occupied caves in the immediate vicinity makes it highly likely that this feature
contains listed karst invertebrate species.”
Feature S-17 was evaluated by Pape-Dawson permitted individuals (professional geoscientist and
biologist) to determine if the features or openings might represent listed invertebrate habitat and
followed the five-step approach outlined in Figure 1 below. Excavation was generally performed
with hand tools until encountering solid bedrock with no portals, packed clay with no airflow
present, or clay-rich organic soils.

Karst Feature Evaluation

USFWS protocol recommends features determined to contain potential karst invertebrate habitat
are surveyed for listed karst species using the protocol described by USFWS (2011a). Survey
protocol includes a minimum of three surveys spaced at least one week apart, a thorough search
of the void, and collection of a limited number of specimens.
All conclusions, opinions and recommendations in this report are based upon site conditions at the
time of site visit and should not be relied upon to represent conditions at later dates. Erosion or
deposition subsequent to this report can, respectively, expose or cover features.

Karst Feature Evaluation

RESULTS
Features S-17 was identified as having the potential for karst invertebrate habitat according to a
report by Bowman Engineers. After the initial field investigation described in the table below
under “Feature Description and Initial Findings”, Pape-Dawson permitted geologist and biologist
ruled the feature out as being potential karst invertebrate habitat. However, due an email from
Bowman Engineers on September 30, 2016 that included a rebuttal to Pape-Dawson’s findings,
Pape-Dawson personnel went back to the site on October 5, 2016 to hand excavate the feature.
The location of the feature is shown in Exhibit 3 and photos of this excavation are included in
Appendix A. Work completed follow the five-step approach outlined in Figure 1 above.

S-17
Feature Description and Initial Findings
This feature was documented in the Bowman
Engineers 2016 report as potential habitat and
evaluated on September 29, 2016 with the
following findings. The feature consists of a
large, loose rock (i.e. not bedrock) that is on a
hillside. Evidence of surface water flow
downgradient is apparent along the hillside. It
appears surface water has washed out soil on the
upgradient side of this large rock causing a small
depression or “void” below it. However, no
evidence of enhanced infiltration or connection
to the subsurface via a karst void was observed.
The soil below the rock was probed to reveal
clayey soils consistent with the soils in the
immediate surrounding area. In addition, no
voids formed by karst or geologic processes
were observed or felt during probing.
Therefore, this feature was ruled out as having
the potential to contain karst invertebrate habitat
based on USFWS protocol. Work completed to
Step 3a.

Findings After Hand Excavation
Subsequent to Pape-Dawson’s findings on September 29, 2016
was an email from Bowman insisting Feature S-17 was potential
habitat. Therefore, Pape-Dawson personnel proceeded to hand
excavate Feature S-17 to reveal the presence or absence of a
karst void that had the potential to contain karst invertebrate
habitat on October 5, 2016. The void in question is below a
large rock. Three Pape-Dawson personnel removed the rock by
using a rock bar and tow strap. Once the tow strap was secured
around the rock, it was slid out of the way. Soil with no karst
voids or mesocavernous spaces was visible below the rock. The
soil encountered appeared consistent with the rest of the site.
Small roots from the nearby tree were also present. PapeDawson personnel continued shoveling below the rock to ensure
no voids were present. A red clay layer was encountered and
still no karst voids or portals into the subsurface were found.
Finally, a probe was used to further confirm no voids were
present below the red clay. Harder, packed clay was
encountered and no areas of loose rock or soil was present based
on shoveling or probing. Therefore, this feature was again ruled
out as having the potential to contain karst invertebrate habitat
based on USFWS protcol. Work completed to Step 4a.

CONCLUSIONS
Based on the karst investigation conducted on the site, there is no evidence of karst invertebrate
habitat in feature S-17. While near a fault (Exhibit 4), Feature S-17 appears to be south of the
fault shown in Bowman’s geologic assessment report. Although smaller faults or fractures are
often present en echelon of the main fault, Feature S-17 does not appear to be within the fault or

Karst Feature Evaluation

fracture system. Feature S-17 is located on the side of a hill where many rocks have broken and
slumped due to gravity and overburden. Additionally, during rain events, surface water is flowing
down the hill and washing away soil on the upgradient side of the rock (S-17), which appears to
be the cause of the small “void” described by Bowman Engineers. Further, while the presence of
troglophilic species may indicate the presence of a void, as Bowman stated in their report, voids
that are suitable habitat for troglophilic species need not be karst in origin and do not require any
connection to the subsurface (i.e. animal burrows or hollow tree trunks serve as suitable habitat
for some troglophilic species). A karst void must be present to have potential listed karst
invertebrate habitat. Without surface expression of potential habitat there is no evidence of
potential impacts to listed karst invertebrates in Feature S-17. Should any additional feature be
encountered during construction, consultation with the USFWS or a USFWS-permitted karst
geologist/biologist is recommended.
