Mark's water resources background includes watershed management and master planning; coastal resiliency and adaptation studies, floodplain management; pollutant load assessment; National Pollutant Discharge Elimination System compliance; low impact development (LID); environmental resource permitting; and hydrologic, hydraulic, hydrodynamic, and groundwater flow modeling. He also has extensive experience with GIS applications for spatial analysis, planimetric mapping, and data visualization.
For dozens of municipal and water management district clients, Mark consults on water resources engineering projects. He provided project management, planning, and design expertise for the Alachua County, Florida Stormwater Management Program. This master plan included developing a county-wide hydrologic and hydraulic model and identifying water quality improvement measures to meet TMDL requirements. The plan included a thorough review of maintenance program staffing and equipment resources to help justify future public works budget requirements. The plan culminated in the establishment of a capital improvement project program that included a 10-year planning period and helped justify a stormwater assessment and funding for a dedicated, sustainable stormwater program. Additionally, Mark conducts watershed management plan projects using his expertise with modeling for floodplain delineation. He was the project manager of a comprehensive watershed evaluation for a 400+ square mile area in Marion County, Florida, part of the St. Johns River Water Management District. The project included use of LiDAR data to generate a digital terrain model, a detailed inventory of drainage infrastructure, and the compilation of a detailed, GIS-based data management system to store all available physical and environmental data. This data supported the development of a comprehensive hydrologic and hydraulic model for floodplain mapping purposes.
Mark has completed more than 100 stormwater retrofit projects, ranging from complete subdivision flood rehabilitations to individualized BMPs that address water quality impairments. He was project manager for the development of a LID manual for Orange County, Florida, that included recommendations for site-specific stormwater practices along with regulatory code changes to incentivize development and produce more sustainable and resilient developments. Additionally, he has helped coastal Florida clients in addressing the challenges of infrastructure reliance and adaptation given future climate change projections.
