state a fact about the project

This project surveyed existing techniques for tree and landform preservation/protection and weighed their suitability for application to the highway environment. It provides guidelines that include criteria for decision-makers to use in the identification of safety as well as social concerns affecting the decision, determining what can be saved, why it might be saved, and the cost for different measures available. This report identifies the issues that affect tree and landform preservation and protection, recommends standards and a new specification procedure as part of a tree protection program for TxDOT, and includes guidelines that explain the standards.
