What our Clients have to say.
"ES&A's work is professional, first rate and of high value. For our 102 acre industrial park ES&A designed and managed a technically difficult multi-million dollar wetland restoration project involving resolution of tangled legal issues and permitting from five City, State and Federal agencies". 
Kevin Loftus – Jameson Partners LLC

"ESA should get some kind of award for getting the City a permit ahead of others who have been in the system longer with less impactful projects. Great job!"

Ray Lanham, PE, Oregon State Marine Board

 "ES&A has been great to work with. I appreciate their attention to detail and responsiveness to all of our questions. I am very pleased that we have gotten through the process and have our permits so we can move forward with the next step."
Shane Witham, City of Keizer Community Development Department
