Retaining Wall Manual and Policy

The manual has been established to meet the following objectives:
In addition, it is the intent of this policy to initiate a process for review and approval for both permanent and critical temporary proprietary wall systems so that a list of approved wall systems can be established. A critical temporary wall is one that is necessary to maintain the safety of the traveling public or structural integrity of nearby structures and utilities for the duration of the construction contract.
