Bullfrog Campground and Storm Water Drainage Improvements
The National Park Service proposes to improve water drainage in the Bullfrog developed area of Glen Canyon National Recreation Area (Glen Canyon).
Improvements to surface water flow are needed to address current storm water run-off issues, to prevent damage to existing infrastructure, and to maintain visitor and employee safety. These changes are also needed to support future expansion of the campground and housing area as described in the Glen Canyon Uplake Development Concept Plan (Uplake DCP).
For example, proposed changes to the campground to better serve recreational vehicles (RVs) are precluded by the existing drainage issues. Once addressed, campground and other visitor service improvements can be made as funding becomes available.
Surface flow improvements may include redirecting existing drainage systems around the developed area or modifying the existing drainage system to allow all or some surface flows to move through the developed area in a way that does not put people or park resources at risk. Construction activities would require excavation to alter existing drainage channels and may result in redirecting where storm waters are delivered prior to reaching Lake Powell.
By improving surface water flow conditions the NPS plans to: implement environmentally sound, cost-effective management strategies that pose the least possible risk to people, park resources, and the environment; to provide for the planned development of facilities in the Bullfrog Basin as identified in the Uplake DCP; to reduce operation and maintenance requirements related to surface water drainage; and to maintain visitor experience during construction.
The NPS is preparing an Environmental Assessment (EA) to evaluate different techniques for improving surface water flow in the Bullfrog developed area in a manner that complies with the National Environmental Policy Act (NEPA), the National Historic Preservation Act (NHPA) and other applicable laws, regulations, and policies.
This process will provide a decision-making framework that analyzes a reasonable range of alternatives to meet project objectives, evaluates potential issues and impacts to park resources and values, and identifies how to avoid or minimize the potential for adverse impacts.
