Section 7: Non-Mow or Natural Areas and Acreage EvaluationsAnchor: #i1003110
Each district maintenance engineer, vegetation manager or designated representative must evaluate all unpaved sections of right of way to establish non-mow or natural areas and calculate acreage to be mowed. The department encourages consultation with the Texas Parks and Wildlife Department (TPWD) field biologists to maximize the wildlife habitat benefits on a local basis.Anchor: #i1003120
Establishing Non-Mow or Natural Areas
Maximize the designation of non-mow or natural areas throughout the right of way. Suitable non-mow or natural areas may include steep slopes, wide rights of way, and other areas which are covered with desirable vegetation. Clearly mark these areas to prevent accidental mowing during modified full-width mowing.Anchor: #i1003130
Calculating Acreage to be Mowed
In addition to the establishment of non-mow areas, the amount of modified full-width and strip acreage to be mowed must be calculated in whole acre units for each section of roadway. These figures will be used in drawing up contact bid proposals and determining maintenance costs.
The Maintenance Management Information System (MMIS) Users Manual, Chapter 2, Section 2 (“Acre Calculation Chart”) contains a table for calculating mowing area, shown here as Figure 2-18.
