Black Rock Campground EA Available For Review

The National Park Service (NPS) is making available for public review an Environmental Assessment (EA) for the rehabilitation of Black Rock Campground for drainage and erosion control. The EA evaluated a no-action alternative, in which the campground would continue to be used in its current condition, and localized flooding issues, degraded campsites, and poor vehicle circulation problems would not be addressed. Also evaluated in the EA is a preferred alternative that includes installation of new drainage channels, road realignment, and reconfiguration of the Black Rock campsite layout with provisions for group sites, walk-in camping, and a horse camp, as well as other infrastructure improvements.

Black Rock Campground is sited on 80 acres in the northwest corner of Joshua Tree National Park about one mile south of the town of Yucca Valley. The existing campground facilities include a visitor center, comfort stations, gravel and asphalt roads, and car and recreational vehicle (RV) campsites.

The large Black Rock Canyon watershed outside of the boundaries of the campground currently conveys storm runoff through portions of the campground in an unpredictable manner, resulting in localized erosion and flooding. The campground, acquired by the Park Service in 1976 from a commercial operator, was not designed to adequately convey drainage away from campground facilities. Campground roads are currently aligned so that storm water runs directly down the roads with the potential for damaging campground facilities, natural resources, and adjacent landowner property. Degraded roads and camping areas also have contributed to increased storm runoff, erosion, and sedimentation.

To address these issues, the park is proposing several changes to the campground including drainage improvements to divert storm water runoff away from campground roads and nearby residential properties into appropriate natural drainage channels. Campground roads would be realigned across the topographic contour to prevent conveyance of storm water runoff and reduce the potential for erosion. The proposed realignment of the campground road network would improve accessibility for vehicles, pedestrians, and horseriders, and it would enhance overall circulation. Improvement of campsite layout with better privacy would also be a component of the proposed rehabilitation work. Because public participation is very important to the success of the project, the NPS encourages your review and comment on the EA.
