Title: ENVIRONMENTAL OPPORTUNITIES AND CONSTRAINTS
1ENVIRONMENTAL OPPORTUNITIES AND CONSTRAINTS
- ARCHAEOLOGICAL - HISTORICAL INVESTIGATIONS
- PERMITTING FOR UNAVOIDABLE ENVIRONMENTAL IMPACT
- AREA ENDANGERED SPECIES ISSUES ARE WELL KNOWN
- CONSERVATION AND PRESERVATION
- ENDANGERED SPECIES ARE OF HIGHEST CONCERN
- PRESERVE IMPACTS VS. HABITAT IMPACTS
2ENDANGERED SPECIES ACT
- REQUIRES THAT IMPACTS ON ENDANGERED SPECIES BE
EVALUATED WHEN THEY ARE KNOWN TO BE OR FOUND TO
BE IN THE WORK AREA AND YOU MUST DO ONE OR MORE
THINGS WHERE SPECIES AND THEIR HABITAT ARE
ENCOUNTERED - AVOID THEM. IF YOU CANNOT AVOID THEM
- MINIMIZE THE IMPACTS OF YOUR PROPOSAL ON THE
SPECIES AND THEIR HABITAT. AND IF YOUR MINIMUM
IMPACTS RESULT IN A SITUATION THAT MAY ADVERSELY
IMPACT THEM, THEN YOU MUST - MITIGATE FOR ANY UNAVOIDABLE IMPACTS WHICH MUST
BE INCIDENTAL TO THE PROPOSAL. - AND, YOU MUST DEMONSTRATE THAT THERE IS NO
PRACTICABLE ALTERNATIVE PROPOSAL WITH LESS IMPACT
TO THE SPECIES THAN YOURS - IF A PROPOSAL CANNOT DO THESE THINGS, AN
INCIDENTAL TAKE PERMIT CANNOT BE OBTAINED FROM
THE USFWS TO TAKE ENDANGERED SPECIES.
3TAKE
- Endangered Species Act prohibits take of
endangered species and their habitat. Take is
described as killing, maiming, injuring or
disturbing the life history or habitat of the
species in such a way that it MAY CAUSE harm to
the species, either directly or indirectly, and
this does include the modification to its
habitat or in proximity to habitat. - Obviously, however, once a species habitat is
modified it is no longer regulated as habitat.

- Feb 12, 2007 - met with Mr. Scott Rowin,
biologist and permitting specialist, USFWS - Discussed current best available commercial
science relating impact to Golden-cheeked
Warbler (GCWA) and the Tooth Cave Ground Beetle
(Rp) - USFWS advises that
- take of Rp occurs within 500 feet of occupied
habitat. - take of GCWA occurs within 250 feet of occupied
habitat - indirect take MAY occur beyond those distances as
well under certain circumstances. -
-
7 - In May the Design Oversight Committee met to
discuss results of analysis and ground truth
field work in several alternative routes. - In mid May the recommendations of the technical
consultants were made to the managers of the
three cities and other attendees at the meeting.
- On June 12, the preferred route of the managers
of the three cities was discussed with the USFWS. - Result - the opinion of USFWS biologists,
supported by field work, that the presence of
known, occupied karst habitat in close proximity
to areas of Lime Creek Road, Anderson Mill Road
and Lakeline Boulevard would likely result in a
finding of take for construction in those areas
since those routes do not avoid the species but
another feasible route does. - August 17, USFWS (S. Rowin and A. Arnold) were
again advised of the impact issues for the
several routes for the raw water line project. - Preferred route places raw water line
construction in areas more than 500 feet from all
known karst faunal features, - Preferred route places raw water line more than
250 feet from all known GCWA habitat - Dec. 15, route toured with USFWS representative
and field biologists. - Recommended route avoids endangered species and
their habitat
8 - A biological assessment and biological opinion of
the findings of the technical consultants to use
the previously approved LCRA route was finalized
and has been submitted to the USFWS for their
consideration and concurrence. - An application has been made to the Balcones
Canyonland Preserve manager for a certificate of
participation to cover one small possible GCWA
area on the plant site - A Nationwide Sec 12 Permit application has been
submitted to the U. S. Army Corps of Engineers to
re-use the three already confined and existing
road crossings of waters of the U. S. along the
preferred route. -

9Prior Environmental Assessments
- An environmental assessment for a 50 foot wide
route study area, nearly identical to the
proposed route with nearly identical impacts, was
prepared and submitted by LCRA in 2000. - LCRA also studied alternative routes, discarding
others and ultimately selecting the Trails End
route recommended for use by BCRUA. - LCRA Environmental Assessment was approved under
similar standards of review by the USFWS, by the
Corps of Engineers, by Texas Parks and Wildlife
Department and the Texas Antiquities Commission,
and those agencies individually and collectively
determined that the LCRA project included no
significant adverse impacts neither direct nor
indirect - to waters of the U. S. and wetlands,
to endangered species or to other environmental
elements on this alignment. - There are no known karst features containing
endangered species, nor were any new features
found in our field work on a 1000 foot wide route
study area of the work zone for the preferred
alignment.

15 FEASIBILITY AND PRUDENCE MORE THAN ONE ROUTE
WAS BOTH FEASIBLE AND PRUDENT FROM A NARROW
CONSIDERATION OF ENGINEERING ISSUES.PRESENCE OF
EXISTING ENDANGERED SPECIES PRESERVES COVERING
BROAD AREAS MADE SOME ROUTES FAR LESS FEASIBLE OR
INFEASIBLE THAN OTHERS.IF AN AVOIDANCE
PROPOSAL COULD NOT BE ADVANCED, APPROVAL OF A
HABITAT CONSERVATION PLAN BY THE USFWS THAT
INCLUDES IMPACT TO ONE OR MORE ENDANGERED SPECIES
WOULD BE REQUIRED FOR ANY PROPOSAL TO GO FORWARD.
THE REQUIREMENT TO OBTAIN A CRUCIAL PERMIT FOR
INCIDENTAL TAKE OF Rp COULD NOT BE MET WITHOUT
NEW LOCATIONS OF Rp BEING AVAILABLE FOR
MITIGATION.NO NEW LOCATIONS OF Rp ARE KNOWN
TO EXIST IN THIS REGION AMONG THE
BIOLOGICAL/SPELEOLOGICAL COMMUNITYONE ROUTE,
THAT PROPOSED, WAS FEASIBLE, AND THEREFORE
PRUDENT, FROM THE NARROW CONSIDERATION OF
ENVIRONMENTAL ISSUES.
