High Water Mark offers comprehensive civil and water resources engineering services with a specialty in litigation support and expert consulting. We perform consulting engineering work in the field of hydrology and hydraulics, including advanced hydrologic and hydraulic modeling (HEC-RAS, SRH-2D, TUFLOW, CFD, etc.), FEMA permitting, 408 permits, dam break analysis and emergency action planning, culvert/channel analysis, urban drainage and river hydraulics.
From modeling a stormwater basin’s failure to crafting court-ready exhibits for floodplain disputes, we bring precision, insight and seasoned judgment to every engagement. We understand that every project has its own landscape — ranging from political to physical to legal.
We offer a broad range of consulting engineering solutions and expertise to your water challenges.
Support for plaintiff and defense in civil litigation concerning water, drainage, stormwater and flood-related disputes. Includes forensic engineering, litigation support, flood event simulations, expert reports, deposition preparation, trial testimony and litigation exhibits.
Modeling of watershed behavior, flow paths, rainfall events and flood risk using state-of-the-art tools such as HEC-RAS and HEC-HMS. Our services support design, policy and litigation.
Design review, compliance analysis and planning for municipal and private stormwater systems. These services include permitting support, drainage reports and failure analysis.
Evaluation and mitigation of flood risks with FEMA compliance, LOMR/LOMA support, floodway analysis and community resilience planning.
Water infrastructure inventories and planning for lifecycle maintenance and capital improvements. These services include condition assessments and GIS integration.
Modeling and evaluation of erosion, deposition and geomorphological dynamics within streams and rivers — critical for infrastructure planning and environmental review.
High Water Mark works seamlessly with attorneys, engineers, municipalities and developers to deliver solutions that not only solve today’s problem but anticipate tomorrow’s challenges.
Our deliverables don’t sit on shelves. They sit in courtrooms, city halls and capital planning documents.
