Dear John and Carol,
Run to your nearest bookstore and buy Building Inside Nature's Envelope by Andy Wasowski. A must-read for all Americans moving onto acreage, this book helps you keep control over the building process and protect your trees and other valuable assets. Take photographs of the scarred trees and register the date. You may want to contact an arborist in Denton or Dallas for advice about your injured trees. The best of luck to you.
