I am trying to get some information and ideas to use ‘Diamond Piers’ to support a driveway over a bordering vegetative wetland area  to access building lots. The town of Yarmouth, MA has a conservation restriction regarding areas bordering wetlands and I think the Pin foundation system may be the solution to install a driveway, but I cannot find where this system has been used for this particular purpose. I would most interested to know if anyone has knowledge of the use of this sytem to supoort vehicles necessary for residential access.
