Title 43 › CHAPTER 32B — COLORADO RIVER FLOODWAY › § 1600e
A federal officer, after talking with the Secretary, may spend federal money or give federal help inside the Colorado River Floodway even if section 1600d would otherwise stop it. That money can be used for dams, channels, or levees for flood control, water conservation, power, or water quality; other fixes like drainage to control high groundwater caused by floods; and for keeping, replacing, rebuilding, repairing, or expanding public or tribal roads, bridges, and facilities. Any expansion must be built under the procedures and standards in 23 C.F.R. §650.101 (as it may be changed) and the Floodway boundaries must be adjusted to reflect any flow changes the expansion causes. The officer may also fund military activities needed for national security. The officer may fund other kinds of projects too, but only if the Secretary finds them consistent with the chapter’s purposes. These include nine types of projects: fish and wildlife work and habitat or recreation projects; air and water navigation aids and access; projects eligible under chapter 2003 of title 54; scientific research; emergency actions to save lives and protect property under sections 305 and 306 of the Disaster Relief Act of 1974 (42 U.S.C. 5145 and 5146) limited to what is necessary, and disaster aid under other parts of that Act for people or structures that existed or were substantially under construction on the date ninety days after October 8, 1986, provided those people or the public owner had bought flood insurance if eligible and took prudent steps, as FEMA decides, to reduce future flood damage; public health help like mosquito control; nonstructural riverbank work that restores natural stabilization; publicly or tribally funded compatible recreation (parks, golf courses, docks, boat ramps) and related utility or interpretive work tied to restoring a National Historical Landmark that meet good engineering practice; and compatible agriculture that has no permanent crops and only minimal permanent facilities in the Floodway.
