Hey Charles – rather than spending more $$$ you might try an internship with someplace like Barr Engineering in Minneapolis – they have a lengthy restroration portfolio. If you want hands-on experience you might call them to ask who does the installation of their projects. Ann Riley’s Waterways Restoration Institute in Berkley, CA might be a good internship opportunity.
I don’t know that you will find what you are looking for in an engineering program – most restoration experts I know came from a Master of Science in Landscape Architecture or a landscape ecology background. MAYBE environmental engineering, but you have to be very careful about the program.
Also – a word of warning – you probably should not call yourself a landscape architect on your portfolio. I don’t know what your state’s laws are, but most specifically prohibit that title unless you are licensed…..
Best of luck! Tanya
