2. PORTS HARBORS & BEACHES
Since 1970, CSA has provided support to local municipalities;
county, state, and federal agencies; dredging contractors; port
authorities; shipping companies; and private industry clients in
preparing environmental assessment documents and mitigation
plans, performing marine habitat mapping and data collection
surveys, developing and conducting monitoring programs, and
assessing impacts of marine activities.
CSA’s scientific and technical staff design and perform mitigation
programs associated with port and harbor development, including
seagrass and coral colony relocation from impact footprints
to adjacent locations. CSA also conducts long-term biological
monitoring programs associated with beach restoration and
nourishment projects.
Our staff are highly experienced in a wide variety of environmental
disciplines: biological, chemical, and physical oceanography;
marine ecology; coral reef and seagrass ecology; and marine
mammals and endangered species. Because of the extensive
diversity and experience of in-house personnel, CSA is able
to competitively and efficiently meet our clients’ needs while
maintaining our internal standards of excellence.

3. REPRESENTATIVE PROJECT
PROJECT OVERVIEW
CSA conducted pre-construction (2007, 2008), immediate post-
construction (2010), and 5 years of annual post-construction (2011 to
2015) biological monitoring surveys of nearshore hardbottom offshore
northern Indian River County, Florida, for the Sector 3 Beach and Dune
Restoration Project.
CSA RESPONSIBILITIES
Twenty-one permanent cross-shore monitoring transects were installed,
maintained, and monitored in both project and reference areas. CSA
scientists collected quantitative and qualitative video data along each
transect to determine percent cover of substrate types, wormrock,
macroalgae, corals, sponges, and other benthic fauna. Percent cover
of the benthic groups were also visually estimated in situ by sampling
0.25-m2
quadrats at 12 locations along each transect. In addition, sediment
depth was measured at pre-determined locations along each transect. The
landward edge of exposed hardbottom was mapped to document position
relative to the shoreline to monitorpotential cross-shore transport ofbeach
fill as well as to document potential changes in the benthic community
along the edge. Lastly, aerial imagery was analyzed via classification of
spectral bands and ground-truth verification to produce a habitat map
identifying hardbottom cover within the survey area.
SUMMARY
•• Prepared annual biological montoring reports as well as
comprehensive data deliverables pursuant to FDEP requirements.
•• Mapped, characterized, and quantified hardbottom resources.
•• Assessed potential sedimentation impacts to hardbottom.

4. REPRESENTATIVE PROJECT
PROJECT OVERVIEW
CSA provided marine environmental services for addressing potential
coral and seagrass impacts as part of environmental mitigation activities
associated with the Miami Harbor Construction Dredging (Phase 3) Project.
The Phase 3 dredging consisted of federally authorized improvements to
Miami Harbor, including deepening and widening of several features of the
existing federal channel and berthing areas for the local sponsor, the Port
of Miami. The project was conducted by the U.S. Army Corps of Engineers
(USACE) and the local sponsor, the Port of Miami.
CSA RESPONSIBILITIES
CSA conducted natural resource surveys of coral habitats prior to the
development and approval of a coral relocation plan; conducted pre-
construction seagrass surveys in the ingress/egress routes surrounding
the Julia Tuttle Mitigation Site and Lummus Island Turning Basin staging
area; and created a seagrass transplantation plan for review and approval
by the Client and the USACE. CSA relocated Acropora cervicornis (staghorn
coral) colonies, a species listed as threatened and protected under the ESA,
and non-Acropora hard coral colonies to a hardbottom reef south of the
Miami Harbor Channel. A newly constructed artificial reef also was created
for the project. CSA harvested seagrass from an approved donor area
and transplanted over 115,000 seagrass plants into the 17-acre seagrass
mitigation site. As advanced compensatory mitigation, 644 hard corals
and octocorals as well as 50 barrel sponges were relocated or donated to
the Patricia and Phillip Frost Museum of Science.
SUMMARY
•• Relocated 38 Acropora cervicornis (staghorn coral) colonies.
•• Relocated 924 non-Acropora hard coral colonies.
•• Relocated or donated 644 additional hard corals and octocorals as
well as 50 barrel sponges.
•• Transplanted more than 7 acres of seagrass within the 17-acre
seagrass mitigation site.

5. REPRESENTATIVE PROJECT
PROJECT OVERVIEW
The marine resource assessment conducted for the U.S. Navy under
subcontract to HDR, Inc. consisted of a series of diver surveys to collect
data regarding marine resources in Apra Harbor, Guam. The collected data
were used to assess the impacts of a proposed dredging project on marine
resources and was evaluated for input into a Compensatory Mitigation
Plan for Clean Water Act Section 404 and Rivers and Harbors Act permits.
CSA RESPONSIBILITIES
Marine resource surveys consisted of 5 main tasks:
1. Collection of data at over 100 sites to characterize coral reef
communities within the dredging footprint.
2. Collection and processing of soft bottom samples from 55 sites to
characterize benthic infaunal communities.
3. Characterization of fish and turtle abundance and diversity during
two rounds of surveys at 34 sites. Sea turtles were also censused
during dive scooter surveys throughout the harbor.
4. Reconnaissance of 10 potential reef mitigation sites to provide
information on the relative condition of resources and suitability for
recovery/enhancement.
5. A laboratory dose-response experiment to test sedimentation
impacts on four species of stony corals in Apra Harbor. Tissue
and cellular signs of sedimentation stress were assessed using
histopathological methods.
SUMMARY:
•• Comprehensive characterization of coral, reef fish, sea turtle, and
benthic infauna populations within and adjacent to the dredge
footprint.
•• Assessment of mitigation sites.
•• Identification of sedimentation thresholds for the four most prevalent
species of stony coral.

multidisciplinary projects involving the assessment of
potential environmental impacts in coastal and marine
ecosystems and offer a wide variety of scientific
analysis and field survey services to support our
government clients worldwide.
GOVERNMENT
CSA focuses on providing marine environmental
consulting services associated with the sustainable
exploration, production, and research of energy
resources. Although much of CSA’s activities are
concentrated within the oil and gas industry, we are
experiencing a growing demand for services to support
the expanding technology and regulations associated
with renewable alternative energy sources such as
wind, tidal, solar, and hydroelectric.
