Forensic Hydrology/Expert Witness Testimony

Gaea uses information gathered from historic aerial photographs, historic maps, and public records to determine the hydrologic changes that have taken place of a particular site over time.  With this information, we determine the most likely causes for these changes and detail the impacts of these changes.   

Gaea's approach involves the systematic monitoring and evaluation of the various aspects of a construction project to guarantee that the highest possible standards of quality are being attained.  This includes the regulation of of raw materials, assemblies, products and components, services related to production, and management, production and inspection processes.

Construction Management

Hydraulic and Hydrologic Modeling

Gaea designs water resources projects for navigation, ecosystem restoration, flood control, drainage improvement and shore protection using  ACES/CEDAS, EPA-SWMM, HEC-HMS, HEC-RAS, and AdH modeling software.  We also prepare engineering reports on analyses of water resources in coastal zones and riverine areas. 

Civil Engineering

Gaea prepares drainage reports, water reports, sewer reports, preliminary plat and site plans, master plan reports, final design reports, final improvement plans, paving plans, grading plans, sewer plans, water plans, onsite wastewater treatment design plans, cost estimates and earthwork analysis.  We also provide assistance and support for public hearings.

Environmental Consulting and Engineering

Gaea offers a wide range of environmental services including phase I and phase II environmental site assessments, environmental assessments, environmental impact statements, wetland delineation and determination, LA pollutant discharge elimination system stormwater pollution prevention plans and risk assessments.

Coastal Engineering

Gaea engineers and specialists are experts in addressing the unique issues that arise during design and construction in coastal and estuarine systems.  We provide risk analysis, environmental impact assessment, coastal zone management, ecosystem restoration, beach and shoreline stabilization and wetlands investigations.  

Green Infrastructure 

Gaea's multidisciplinary staff is well equipped to tackle green infrastructure design or retrofit challenges at a range of scales.  We combine our specialties to address stormwater quantity and quality objectives, vegetation requirements, utility conflicts, and monitoring goals.

Cultural Resources

Gaea performs Cultural Resource assessments for historic, architectural, and archaeological resources as required by the National Historic Preservation Act, the Archaeological Resources Protection Act, National Environmental Projection Act, and other federal, state, and local regulations for permitting and planning.  Gaea also provides historic preservation consulting services for construction and rehabilitation projects. 

Landscape Architecture

Gaea prepares landscape solutions for residential, commercial and public projects that are both functional and aesthetically pleasing. We work with clients and stakeholders to produce plans and specifications for planting, hardscaping, site furnishings, grading, stormwater management, and maintenance.  

Historic Research Services

Gaea performs historic site assessments and permit history analyses.  This involves consulting an array of past aerial photographs, newspaper articles from local and state publications, permit databases and local records.  We follow a similar approach when performing genealogical research for private clients and expert witness testimony.

Structural Engineering

Gaea performs structural design for concrete slabs and steel structures at industrial facilities.  Gaea also applies this skill set in coastal structural design and load case analyses.




Gaea serves as agents for our clients preparing City, Parish, State, and Federal permit applications with a 100% approval rating.  We have facilitated and obtained permits from LA Department of Environmental Quality, LA Department of Natural Resources, US Army Corps of Engineers, New Orleans Department of Public Works, and clearances from LA Department of Wildlife and Fisheries and individual parishes.
