1. PROJECT DESCRIPTION
2. SCOPE OF WORK
The scope of Work for this project has been divided into the following tasks:
• Task 1: TCEQ Geologic Assessment and Hydrogeological Investigation of the Onion
Fault
• Task 2: Jollyville Plateau Salamander Presence / Absence Investigation
2.1. Work Breakdown Structure Tasks and Description
2.1.1 Task 1: TCEQ Geologic Assessment and Hydrogeological Investigation of the Onion
Fault
Task Description: Under this task, a Cambrian Registered Professional Geoscientist who
is permitted by the U.S. Fish and Wildlife Service (USFWS) to conduct karst surveys will
visit the project area (subject to right of entry conditions) to evaluate surface features that
may be indicative of avenues for aquifer recharge and which may be indicative of sub-
surface habitat for the Jollyville Plateau Salamander (Eurycea tonkawae). The field work
will generally conform to the "Instructions to Geologists for Geologic Assessments on
the Edwards Aquifer Recharge/Transition Zones" as written by the Texas Commission on
Environmental Quality (TCEQ). Data collected during this effort will be used to prepare
an updated TCEQ Geologic Assessment report covering both tracts being considered for
purchase. This report is required for all development activities on the recharge zone. The
report will meet the requirements for enrollment in the Williamson County Regional
Habitat Conservation Plan (RI -ICP) for potential take of endangered karst invertebrates.
Based on the results of our findings, additional excavation work and biological surveys
may be required, although they are not expected based on the results of our previous
work in the project area.
This investigation will go beyond the normal minimum required to satisfy TCEQ
requirements in order to ascertain the hydrologic function, if any, of the Onion Fault. The
Onion Fault is indicated by at least one recent geological map as crossing the tract.
Functionality of the property would be considerably restricted if the fault is found to act
as a recharge feature and a protective setback is required. The primary tool for assessing
this matter will be a series of on-site infiltration tests.
Cambrian personnel recently conducted infiltration tests on a 2.039 -acre property located
at 2721, Sam Bass Road, west of the current project area. The results of Cambrian's
infiltration tests were widely variable and no significant linearity could be attributed to
tl�e action of the fault. The variability in the infiltration tests was most likely attributed to
prvviouq ground disturbance that has occurred on the site or differences between mapped
soil unit, rather than influence from the Onion Fault. Because the fault likely occurs east
of the 2721 Sam Bass Road tract, the Onion Fault could occur on the present tract.
2.1.2 Task 2: Jollyville Plateau Salamander Presence / Absence Investigation
Task Description: The project is crossed by Dry Fork of Brushy Creek, which may or
may not be occupied by the Jollyville Plateau Salamander (JPS, Eurycea tonkawae). The
JPS was listed as threatened under the Endangered Species Act in September of 2013.
The species is known to occur in spring runs located both upstream and downstream of
the project within the Brushy Creek drainage basin and additional habitat may occur
elsewhere in the basin. These factors indicate that habitat may be present in close
proximity to the project. Cambrian personnel recently completed a JPS presence/absence
report for a 2.039 -acre property located at 2721 Sam Bass Road, immediately upstream
from the current property area. After thoroughly surveying the area in accordance with
USFW 2014 protocols, Cambrian concluded with 95% confidence that the Jollyville
Plateau salamander was absent from the wetted section of that property.
Under this task, Cambrian will conduct a presence/absence investigation for the JPS in
the spring -fed creek running along the southern boundary of the property. As required by
the USFWS for conducting JPS salamander surveys (USFWS 2014), the entire property
area of the channel will be surveyed fifteen times under suitable sampling conditions and
during months when the Jollyville Salamander is known to have high detectability (April -
September). Our sampling method for the spring and shallow areas of Brushy Creek will
conform the visual encounter survey methods used by Pierce (Pierce et al. 20 10) for other
Eurycea sites in Williamson County. If salamanders have not been discovered by at the
eleventh survey, bottle traps will be deployed within the channel and checked for
Ewycea specimens every 24 hours. Due to the physical parameters of the habitat, bottle
traps may be deployed earlier than that required by the USFWS. If encountered,
individual salamanders will be temporarily captured and photo -documented before being
released and surveys will cease. No specimens will be collected permanently. A habitat
assessment report presenting the results of our investigation will be provided.
