Task 10 — Construction Phase Environmental Services
The proposed project intends to construct a new roadway crossing, which will require partial
dewatering of an impoundment of Dry Fork Creek within the City of Round Rock, Texas
(30.529953, -97.723439). Under current regulatory guidance, the Texas Parks and Wildlife
Department (TPWD) regulates any activity that may result in a loss of aquatic life. To minimize
impacts to protected aquatic biota, TPWD requires the development and execution of an Aquatic
Resource Relocation Plan (ARRP). Components of an ARRP include concentrated efforts to
survey for, and relocate (if found), freshwater mussels, fishes, turtles, and crayfish (herein
collectively referred to as "aquatic life"). Halff maintains specialized biologists (Stream Ecologist)
with the necessary scientific permits to survey for, collect, and relocate the above-mentioned taxa
as part of ARRP activities.
TPWD is particularly concerned with declining freshwater mussel populations and has special
relocation procedures for this taxon. The intensity of mussel survey and relocation efforts are
generally defined by what may be found within a given stream reach. Under current regulatory
guidance, TPWD maintains a spatial dataset which groups streams, or in some cases stream
segments, into five distinct stream groupings based on known mussel fauna and state/federal-
listing status.
Currently, mussel stream groupings do not list Dry Fork Creek within the current dataset.
Additionally, as an impoundment of a riverine feature, current regulatory guidance states that
methodology for recovery and relocation of freshwater mussels should match expected
freshwater mussel occupancy and diversity. To determine ARRP requirements, Halff discussed
the proposed project with a TPWD Kills and Spills Biologist on 3/24/2023. TPWD indicated that
since the impoundment was not included in a stream grouping and is unlikely to include any listed
aquatic fauna, ARRP methodology could consist of monitoring the site during active dewatering
to move stranded aquatic life to another nearby impoundment upstream of the proposed project
area.
Therefore, an ARRP will be developed, which includes methodology for the recovery and
relocation of stranded aquatic life during active dewatering, in addition to implementation of best
management practices necessary to prevent unnecessary losses of aquatic life and to avoid
compliance issues with TPWD. This process, in its entirety, is partitioned into the tasks described
on subsequent pages of this document.
10.1 Coordination and ARRP Development
Development and maintenance of effective communication between the City, Halff,
government agencies, and the Contractor will be a key factor in achieving successful
and expedient project completion. Halff will provide the City guidance and assist with
agency staff coordination via e-mail and up to three (3) conference calls. This task
also includes development of the ARRP, as coordination with agency staff and the
Exhibit B
Wyoming Springs Segment 1 —Final Design and Permitting SC#2 Page 2 of 7
City is necessary to develop the ARRP and application for a TPWD Introduction
Permit.
Deliverables:
• Electronic copies of meeting minutes from conference calls
• Electronic copies of the Aquatic Resource Relocation Plan and TPWD Introduction
Permit application
10.2 ARRP Field Relocations
Following the competition of Task 10.1, Halff will be on site with the Contractor
during dewatering efforts to collect, enumerate, and relocate stranded aquatic life to
prevent losses of these protected aquatic resources and prevent compliance issues
with state/federal agencies. Halff will assume reporting of aquatic life authorized
under the scientific research permit of the Stream Ecologist. This Task includes
acquiring a TPWD-issued Introduction Permit.
Deliverable:
■ Electronic copies of field notes/data collected while assisting with the aquatic life
relocation effort
10.3 ARRP Reporting
Following the competition of Task 10.2, Halff will produce both a relocation report to
satisfy regulatory requirements with TPWD. This report will be submitted to the Client
and TPWD.
Deliverable:
■ Electronic copies of the Aquatic Resource Relocation Report
10.4 Solution Feature Evaluations
• Solution cavity evaluations and reporting for the Texas Commission on
Environmental Quality (TCEQ) will be handled by subconsultant SWCA
(handling of 5 features is budgeted)
Deliverable:
• Report submitted to TCEQ in accordance with Edwards Aquifer regulations
EXCLUSIONS/OTHER ITEMS NOT INCLUDED IN THE PROJECT SCOPE
■ Task 10.1 does not include in-person meetings.
■ This scope does not include laboratory identification (i.e., DNA or other) of freshwater
mussels.
• Post-relocation monitoring of aquatic species, if required, is not included within this scope
of work.
■ Halff personnel maintain a Scientific Permit for Research (SPR) with specific authority to
collect and relocate most aquatic organisms, including state-listed fishes and mussel, in
the state of Texas. It is anticipated that all species which may be encountered within the
proposed project area are authorized under the aforementioned permit; however, should
Exhibit B
Wyoming Springs Segment 1 —Final Design and Permitting SC#2 Page 3 of 7
an organism be encountered which is not authorized under the permit, all activities will be
stopped and the applicable state agency will be contacted for next steps.
• The Stream Ecologist does not maintain a federal permit at this time and any
collection/handling/relocation of any federally-listed species will be done under the
direction of the federally-permitted individual selected by the City (if applicable).
• While the presence of state or federally-listed mussels and/or fish is not anticipated,
additional protocols and regulations may apply if an undocumented population of federal
or state list species is found. An additional scope and fee will be produced should any
additional effort be required to comply with state and/or federal regulations concerning
protected wildlife.
ASSUMPTIONS
• Locations within the project area are on city right-of-way, and right of entry/access will be
provided to Halff.
• ARRPs require a TPWD-issued Introduction Permit. Once the permit is issued, the permit
is active for 30 days before the permit expires and another permit must be issued. The
City will coordinate with Halff at least 30 days in advance to conduct ARRP activities and
allow sufficient time for coordination with TPWD.
• The City will coordinate with Halff regarding the timing and methodology of the proposed
ARRP and mussel relocation activities.
• It is estimated that Task 10.2 activities would require three (3) ten (10)-hour days (each)
by the Stream Ecologist and two (2) Unpermitted Assistants (other Halff biologists) to
complete. Should additional field days be required per TPWD recommendation, or in the
event of discovery of a significant freshwater mussel bed, or to prevent unnecessary
losses of other aquatic life from the proposed activities, these additional services would
be completed under a separate scope of work.
■ TPWD expects that the holder of the Scientific Permit for Research (Halff's Stream
Ecologist) use field data and results, species vouchers (live-captured specimens,
specimens found dead, mussel valves, etc.), photographs, and reports for scientific
research, the results of which may be used for, but not limited to, presentations and
published in publicly available, peer-reviewed, scientific journals.
LIMITATIONS
• The exact timing of the aquatic life relocation activities will be dependent upon conditions
within the impoundment, (i.e., flow levels, etc.), other weather-related conditions, and
other potential issues and/or concerns provided by the City or Halff. Due to the anticipated
presence of various hazardous conditions within the project area (i.e., potential obstacles
in the waterways, temperature, etc.), field activities will be conducted only when conditions
are deemed safe.
■ In the event that aquatic life are harmed or killed during recovery and/or relocation efforts,
Halff will not be held liable. Halff will use best management practices and will conduct
recovery and relocation activities in accordance with the TPWD-approved ARRP
submitted by the City.
