Critical Habitat Reform Act of 2004

Critical Habitat Reform Act of 2003 - Amends the Endangered Species Act of 1973 to require the process for designating critical habitat to be practicable, economically feasible, and concurrent with the approval of a recovery plan for a species.

Prohibits the relevant Secretary (the Secretary of the Interior or the Secretary of Commerce) from designating an area as critical habitat of a species, and any designation of critical habitat of a species from applying to an area, if the area is subject to: (1) a habitat conservation plan that the Secretary determines provides protection for habitat of the species that is substantially equivalent to the protection that would be provided by such designation; or (2) a State or Federal land conservation program that provides such protection.

Directs the Secretary, in determining whether an area is critical habit, to seek and consider information from local governments in the vicinity of the area, including local resource data maps.

Specifies factors for consideration of the economic impact on landowners under the Act, including lost revenues and costs associated with preparing reports, surveys, and analyses.

Modifies the contents of the required notice of proposed designation of critical habit to include any municipality having administrative jurisdiction over the area in which the species is believed to occur.

Requires the Secretary, with respect to a regulation to designate or revise a designation of critical habitat, to: (1) maintain, on a publicly accessible Internet page of the relevant Department (Interior or Commerce), Geographical Information System maps and coordinates of the area; and (2) include in such notice a reference to the Internet page.
