I need an engineer to do a soil perc. and storm water study for a patio job in Wayne, PA. Tredyffrin Township. I was going through Gilmore & Associates as recommended by EP Henry, but the guy said he would get back to me this week and when I called today, his office said he's on vacation for a week. Looking for someone who has specifically dealt with storm water management issues. Can anyone out this way recommend someone? Thanks!
