Madison has over 5 year of water resource engineering experience with projects scattered from the southeast to the northwest regions of the United States (US). He is a licensed professional engineer (PE) in Idaho and is a certified floodplain manager (CFM). He has performed task manager and/or technical roles for the hydrologic and hydraulic analysis on bridges and culverts being replaced in Utah, Arizona, Idaho, Georgia, and South Carolina. This includes 1D and 2D modeling in HEC-RAS and SRH-2D, scour analysis, riprap sizing, freeboard determination, and floodplain extents during design and check flood events. He executed a variety of hydrologic analyses to compare and determine flowrates using stream gage data (Bulletin 17C), HEC-HMS, FEMA analysis, canal flow, or dam release rates.

Additionally, he has worked on projects that have allowed him to model and report the runoff impacts of large scale, proposed solar sites and luxury residential communities across the US using RAS 2D rain-on-mesh modeling and ArcGIS Pro. He has also performed roadway drainage design to capture and convey runoff from surface water back to groundwater using Open Roads Designer, FlowMaster, and ACHD spreadsheets. Madison has experience with FEMA no-rise, LOMR, and LOMR-F flood studies for proposed buildings and bridges in FEMA SFHA’s. This was useful knowledge when he calculated, modeled and reported runoff design for proposed development using StormCAD, FlowMaster, HY-8, and ACHD spreadsheets.
