Throughout the AACLP, the IID has worked with the U.S. Bureau of Reclamation (Reclamation) to minimize impacts to the environment from construction activities. The IID conducted detailed studies to identify sensitive plants, wildlife and habitat that could be affected. The IID will implement an environmental mitigation-monitoring program to ensure environmental protection during construction. The mitigation monitoring program includes: 

• Avoiding and minimizing impacts to sensitive biological resources
• Preserving offsite mitigation lands
• Compensating for impacts by restoring affected habitat

The environmental studies conducted along the AACLP identified sensitive cultural sites, and sensitive plant and wildlife species that may be impacted by the work activities. The AACLP mitigation program includes the restoration desert dune plant species, flat-tailed horned lizard compensation, a wetland enhancement between Drops 3 and 4, large mammal tracking, canal fishery mitigation compensation, razorback sucker retrieval, and treatment for cultural resources.
