My name is Nadean, and I am a self-professed stormwater nerd. I started working with stormwater compliance in the Air Force and quickly realized how important stormwater pollution prevention was to the ecosystem. During my military career, I focused on construction and other civil engineering operations duties.  When I separated from the military, I initially worked as a Geotechnical Engineer (that is a fancy way of saying that I worked in dirt) but I found my way back to my true love of stormwater management in 2014. I created a Stormwater Management division at a local engineering firm, focused on helping clients manage the stormwater regulations that affect their development, as well as ensuring that the sites are limiting their contribution to Stormwater Pollution. I saw another stormwater need developing and decided to tackle it next.  I started up Oya Construction as a way to properly install and maintain stormwater controls on construction sites, reducing the sediment deposition into waterways.  I am passionate about keeping our waterways clean and our environment beautiful.
