Or call us: (760) 895-4411

When a court case requires an expert in highway drainage system analysis, a seasoned hydrologist with experience in litigation support can be the key to a comprehensive understanding of the case. At WRCS (Water Resources Consulting Services), we bring over 35 years of unparalleled expertise, offering top-tier professional witness services tailored to meet the unique demands of your case.

Roadway & Highway Drainage:

When highway accidents happen, it is often under rainy or flooded highway conditions. That’s when the analysis of the roadway drainage system and its maintenance becomes important in determining causative factors for the accident. WRCS has worked on scores of freeway, highway and roadway drainage design cases and provided trial testimony in several of those cases.

The Federal Highway Administration (FHWA) administers national standards for highway drainage design, maintenance and operation. Most states have transportation departments that issue their own drainage design regulations, but these will always be subject to FHWA regulations. Even most city street drainage design is subject to the design standards of that city.
