provides a graphic description of how the zones are organized. A project’s zone classification is determined by which of the highlighted areas are expected to occur in the project. This table is a summary of the development characteristics of the various development zones

For instance, if a project is expected to require continuous hand-weeding after establishment, it is considered to be a Zone I landscape. Likewise, any project that can be mowed only by push mowers is also rated as a Zone I.

The zones are necessarily vague since many specific design decisions affecting maintenance are yet to be made at the site-design level. TxDOT will make the final determination of the level of management.
