WETLAND CROSSING
Wetland crossings must be avoided wherever possible. Where that is not possible, the location of the
crossing and its orientation must be selected so as to have the least possible impact upon the wetland.
All wetland crossings must conform to Chapter 105 permitting requirements.
Temporary crossings should be constructed from materials that can be placed with a minimum of
disturbance to the soil surface and completely removed when no longer needed. Some examples of
stabilized crossing methods are illustrated in Figures 3.5 through 3.7 below.
