Safety - Drones pose a potential hazard to visitors due to malfunction or negligent operation.
b. Since UAS operation can be a safety and security risk to USACE infrastructure, as well to staff, visitors, environmental features, and wildlife at USACE projects, all private and public recreational/hobby and/or commercial use of UAS must satisfy all FAA requirements, applicable state and local laws, and USACE regulations.
NOTE: No areas of the Canal have been designated as authorized for aircraft operation by the New England District Commander. Therefore all aircraft operation (including UAS/Drones) is prohibited at the Cape Cod Canal per 36 CFR, Chapter III, Part 327.4, Aircraft. (Public safety agency official use is exempt)
BE ADVISED: Reference aid maps such as B4UFLY and AIRMAP may not indicate that the Cape Cod Canal is a restricted area. This does not remove or prevent the enforcement of restrictions imposed by 36 CFR, Chapter III Part 327, under the authority of 16 U.S.C. 460d; 16 U.S.C. 4601-6a; Sec. 210, Pub. L. 90-483, 82 Stat. 746.; 33 U.S.C. 1, 28 Stat. 362.
