Aaron Gwinnup has joined the McClure team as Team Leader – Environmental to lead the growth and development of the Environmental team. He brings 15 years of engineering experience and over 20 additional years in construction and project management.

Gwinnup’s engineering experience includes consulting and academic facets. He worked at the Iowa Institute for Hydraulic Research for three years researching phytoremediation and Midwestern water quality issues. His master’s thesis investigated Midwestern flooding and its impact on the Gulf of Mexico “dead zone”. He joined expeditions to the Gulf twice, to help measure the dead zone in 2008 and to collect oil-soaked salt marsh samples during the 2010 Deepwater Horizon oil spill.

His consulting career has included a wide range of projects including stormwater BMP design, stream, prairie, and wetland restoration, hydraulic modeling and dam modification, floodplain mapping and permitting, and major civil works such as landfill construction, park development, and conventional stormwater design. He has worked in ten US states and two Canadian provinces and has been retained by state agencies, cities, counties, watershed management organizations, and also private entities and NGOs in the implementation of hundreds of water-resources and ecological restoration projects.
