GTS’ Environmental Group commits its broad-based talents to
support public- and private-sector projects by evaluating any adverse
impacts on the environment and developing solutions to protect
sensitive areas and remediate problems. With a knowledgeable staff that
encompasses the major environmental disciplines, GTS has the resources
to take most projects from conception through construction.
GTS Stream Team
(Watershed Management and Restoration)
Recognizing the multi-disciplined nature of watershed assessment,
planning and restoration, GTS has assembled a team of water resources
specialists with diverse backgrounds to enable us to deliver a full
range of products and services. Individual Stream Team members have
training and experience in geomorphology, biology, hydrology,
hydraulics, soils, aquatic and terrestrial ecology, geographic
information systems, environmental and civil engineering, and community
relations. Staff members have completed hands-on training in the
natural stream channel design methods pioneered by hydrologist David
Rosgen of Colorado. Vegetative restoration design techniques, including
bioengineering approaches to streambank stabilization, are also
Assessments and Site Characterizations
GTS’ staff has extensive knowledge of the environmental site
assessment processes and procedures for both Phase I and Phase II
assessments, along with a depth of experience that comes from a 35-year
history of working within the transportation arena. Our services range
from field screening methods to intrusive multi-media sampling for
laboratory analysis, and we have a history of developing creative
environmental solutions to reduce costs and avoid wasted effort.
Endangered Species Surveys
GTS’ environmental team has a well-rounded knowledge of
community ecology and wildlife habitat assessments as well as an
understanding of abiotic and biotic components (soils, geology, water,
nutrients, producers, consumers, and decomposers). GTS has provided
habitat assessment and habitat designs for both terrestrial and aquatic
systems and has performed numerous assessments for both state and
federal threatened, endangered, and special concern species of flora
Identification, Delineation and Design
In addition to habitat community assessments, GTS has extensive
experience performing wetland identifications and delineations in
accordance with the U.S. Army Corps of Engineers’ Wetland
Delineation Manual (1987) and Section 404 of the 1977 Clean Water Act.
GTS has been involved with numerous projects requiring clearance under
the National Environmental Policy Act (NEPA) of 1969. GTS has also
designed replacement wetlands as well as wetlands that provide natural
treatment systems for highway stormwater runoff.
Management Practices (BMPs)
GTS frequently designs Best Management Practices to prevent or reduce
water pollution for stormwater management, watershed protection and
treatment of runoff from various sites and operations.
Information Systems (GIS)
GIS has become an excellent tool to assimilate land use, watershed,
transportation and environmental information into planning activities
as well as many other useful applications. GIS combines databases with
mapping capabilities, enabling an impressive array of information to be
readily available at the stroke of a computer key.
Public and media relations have taken on a bigger role in
today’s environmental projects, and GTS’ staff is
adept at putting together all the components of an effective program.
Public involvement activities can be as simple as holding a public
meeting or as complex as developing an interactive web site, conducting
community surveys and focus groups, creating newsletters and planning
GTS has sophisticated geophysical
capabilities, which can be
useful in detecting buried tanks and drums, abandoned landfills, water
tables, and groundwater contaminant plumes, for example.
Air Quality and
Staff is experienced in conducting air quality and noise studies for
public transportation projects as well as private industry applications.
