Local conditions
Environmental conditions in Jefferson Parish
Jefferson Parish sits almost entirely below sea level on the Mississippi River delta, a landscape shaped by centuries of sediment deposition, industrial corridor activity along the river, and recurring hurricane and flood events. That combination — low-lying fill soils, a history of heavy industrial land use upriver and along the parish's own chemical and petrochemical corridor, and groundwater that sits very close to the surface — means environmental unknowns can surface quickly during a transaction or construction project if they are not addressed early. Our environmental services team supports contractors, developers, and engineers working across Jefferson Parish with Phase I and Phase II Environmental Site Assessments, soil and groundwater sampling, and construction-phase environmental monitoring. Work is dispatched through our Houston regional hub on a scheduled and project-based basis. Each engagement is coordinated in advance so the right personnel and equipment arrive ready to perform — no service promises beyond what logistics actually support.
Louisiana's subtropical climate produces high annual rainfall, and Jefferson Parish's low-elevation soils — often soft clays, silts, and hydraulic fills — allow contaminants to migrate vertically to shallow groundwater with limited attenuation. Construction projects that disturb existing fill or encounter unexpected subsurface conditions benefit from pre-construction environmental assessment rather than reactive response.
FAQ · Jefferson Parish
How does Jefferson Parish's shallow groundwater affect Phase II sampling plans?
Groundwater in much of Jefferson Parish can be encountered within a few feet of the surface, which compresses the vadose zone where soil attenuation normally occurs. A Phase II sampling plan must account for this by setting shallow monitoring point depths appropriately, selecting field screening methods suited to saturated conditions, and using sampling protocols consistent with ASTM E1903 guidance to ensure representative results are collected and documented.
Are there particular contaminants of concern given Jefferson Parish's industrial and port history?
The Mississippi River corridor through Jefferson Parish has historically supported petrochemical, refining, and bulk-transfer operations. Common contaminants of concern in assessments for properties near these corridors include petroleum hydrocarbons, chlorinated solvents, and heavy metals. A thorough ASTM E1527-21 Phase I records review — including regulatory agency databases, historical aerial photography, and Sanborn fire insurance maps — is the appropriate first step for any acquisition in the area.
What environmental support do you provide during active construction in Jefferson Parish when unexpected soil conditions are encountered?
When excavation uncovers discolored soil, odors, or buried debris consistent with historical fill or release events, construction-phase environmental support includes field screening with a photoionization detector, documentation of anomalous material, and collection of confirmation samples. This limits project delays by giving the project team usable data quickly and supporting decisions about whether material requires characterization before off-site disposal under Louisiana DEQ and EPA waste classification requirements.
