Construction and maintenance on communication towers and other tall, artificial structures can cause disturbance to eagle nests, communal roosts, or foraging areas. If your tower construction or maintenance project is within 660 feet of an eagle nest, communal roost, or foraging area, you will need to follow specific measures described below to prevent disturbance to eagles.
If an eagle nests or roosts on your tower, you must obtain a permit to access the tower (including emergencies).
Build new towers with or on existing towers; ideally collocated within existing antenna farms or other structures (e.g., billboard, water tower, or building mount).
If you can't collocate, place the communication towers at least 660 feet away from nests, foraging areas, and communal roost sites. Towers should not be sited in or near bird concentration areas or in known migratory or daily movement flyways. Keep a record of your siting decisions in writing.
Use monopole technology to minimize nesting and perching opportunities. Equip the structures with devices to discourage eagles from building nests or install nesting platforms that will safely accommodate eagle nests without interfering with structure performance or access.
To reduce the possibility of unintentional killing of eagles, towers should be less than 200 feet tall without guidewires.
