7.2 Recommendations
Soil disturbance associated with the construction in the project area may promote conditions for
the spread of invasive noxious weeds. The application of an aggressive weed management plan
for this project site is recommended to: 1) prevent the invasion and expanded range of noxious
weeds and 2) ensure the establishment of desirable plant life upon rehabilitation of the proposed
project area.
7.3 Integrated Weed Management Plan: A noxious and invasive integrated weed
management plan should be developed for the project area. The plan should be addressed as a
separate document and meet Mesa County standards. A summary of best management practices
to control noxious weeds includes the following:
• Conduct field surveys prior to construction to identify existing noxious weed infestations
within the project area.
• Initiate control measures outlined in a Noxious Weed Management Plan for the project
area. Follow the recommendations set forth in the plan. The plan should complement the
plan for site reclamation following construction.
• Consider tamarisk control project. Work with the local Tamarisk Coalition in an effort to
reduce or eliminate tamarisk and replace with native plant species. The tamarisk leaf
beetle may be introduced to control the growth of this species (likely already occurs).

• Use certified weed -free erosion control and reclamation materials (i.e., straw bales and
seed mixes).
• Monitor the distribution and density of noxious weeds on the property and control and/or
eradicate any new or expanded population for the life of the project.
• Promptly re- contour and re- vegetate all disturbed areas with the seed mix specified in the
approved weed/reclamation plan.
• Upon detection of noxious, non - native, and /or invasive plant species, control their
presence before seed production using materials and methods as outlined in the approved
weed plan or with the approval of the county weed supervisor. Application of herbicides
will occur under field supervision of an EPA certified pesticide applicator. Herbicides
must be registered by the EPA. Herbicides intended for use in riparian areas will be
