Two stretches of Arizona's Santa Cruz River are still legally "navigable" much to the chagrin of a home builders agency after the D.C. Circuit Court of Appeals ruled in favor of the Environmental Protection Agency.
The National Association of Home Builders and its two Arizona affiliates had tried to challenge the EPA's recent designation of the two river sections. The designation is important to home builders because streams that are legally navigable fall under the federal Clean Water Act, which imposes restrictions on any discharges into water that leads to those streams.
