Local conditions
Environmental conditions in Orleans Parish
Orleans Parish sits on low-lying deltaic soils, much of it below sea level, in a subtropical climate that sees heavy seasonal rainfall and periodic hurricane-driven flooding. That combination means contaminants can migrate laterally and vertically faster than in more stable geologic settings, and historical land uses—industrial waterfront operations, petroleum storage, manufactured gas plants, rail yards—have left an environmental legacy that affects transactions and redevelopment across the parish. Lenders, buyers, and public agencies routinely require thorough due diligence before a project can close or break ground. Our firm provides Phase I and Phase II Environmental Site Assessments and construction-phase environmental support to keep that process on schedule. Dispatched through our Houston regional hub, our team brings structured field protocols, a laboratory operating under a documented quality system, and clear written deliverables that satisfy lender, regulatory, and project team requirements in this market.
The saturated, highly compressible alluvial and deltaic soils common throughout Orleans Parish create shallow groundwater conditions that can concentrate and transport subsurface contaminants quickly, which is a material factor in scoping any subsurface investigation. Seasonal heavy rainfall and the parish's subtropical climate also mean that surface drainage patterns and potential contaminant pathways should be evaluated with local hydrologic conditions in mind.
FAQ · Orleans Parish
How do Orleans Parish's shallow groundwater conditions affect the scope of a Phase II investigation?
Shallow water tables—often encountered within a few feet of grade across much of the parish—compress the unsaturated zone where soils can attenuate contaminants. This typically requires closer attention to groundwater sampling alongside soil sampling and may influence boring depths, purge volumes, and the number of monitoring points needed to characterize a release adequately. Scope decisions are made on a site-specific basis consistent with ASTM E1903 guidance.
What Louisiana state regulatory programs should we be aware of when planning a redevelopment ESA in Orleans Parish?
Louisiana DEQ administers the Voluntary Remediation Program and the Risk Evaluation/Corrective Action Program, both of which can affect cleanup standards and closure documentation for redevelopment sites. Sites involving underground storage tanks fall under LDEQ's UST program. Understanding which program applies early in due diligence helps scope the ESA correctly and avoids delays when seeking a No Further Action determination or similar regulatory closure.
Can environmental site assessment work be scheduled around the Gulf hurricane season to avoid project delays?
Field work can proceed year-round in Orleans Parish, but project schedules should account for the June–November hurricane season, during which mobilization windows can be interrupted by storm preparation or evacuation orders. We recommend building contingency time into Phase II field schedules that span those months. Report delivery timelines are agreed upon at project kickoff so lenders and closing teams have realistic expectations from the start.
