Danger zones and restricted areas (USACE)

Danger zones, restricted areas and similar regulated water areas in coastal and marine waters (422 polygons) from 33 CFR part 334 and the raster navigational charts; agencyofuse is the using agency (mostly U.S. Navy and Army). A regulation may have several polygons: the id is state + CFR section, and repeats get ':part' suffixes in OBJECTID order.
