Tropical Storm Allison Recovery Project, Harris County, TX  Performed field work in documenting flooding and damages that occurred.

Lake Brauning Thermal Modeling, San Antonio, TX  Performed water quality and temperature modeling in support of new power generation unit on Lake Brauning.

Environmental Exposure and Leptospirosis, Iquitos, Peru   Performed fieldwork and geospatial analysis to determine the source and mitigation strategies for Leptospirosis (a waterborne disease).

White Oak Bayou Flood Control Project, Harris County, TX   Performed H&H analysis for 25 miles to update floodplain maps and propose flooding solutions.

Juan Carlos Martinez, PE, QSD is a Senior Engineer and Senior Associate at Parmar Engineering.  Mr. Martinez has a wealth of knowledge in the field of water resources engineering and has become a vanguard of innovation, technical expertise, and quality assurance in the last ten years. 


Mr. Martinez holds two degrees from the University of Texas at Austin in Biology and Civil Engineering. In his studies, Mr. Martinez specialized in biochemistry, water quality treatment and GIS enabled water resources solutions.


Mr. Martinez has a dedicated history of serving consultancy to large agencies on multi-million dollar, high profile projects.  His project experience is a wide ranging expertise of water resources engineering projects as well as a remote sensing and GIS applications projects. Mr. Martinez is a Licensed Professional Engineer (PE) in California and a Qualified Stormwater Designer (QSD) in California.


Mr. Martinez is a vanguard of innovation in the field.  He has modeled,  designed and built complex coordinated arrays of detention basins in difficult urban environments.  In the modeling arena, he has tested to launch the initial Arc GeoRAS and ArcGeoHMS pre and post processors and was on the engineering team that created the first ArcHydro based model network and flood prediction systems in the country.  Mr. Martinez also managed the aquisition and production of  the largest 1-ft contour equivalent LiDAR topography dataset in the country; a dataset larger than 9,500 square miles.
