Reroutes and Repairs to Flood Damaged Trails

Rocky Mountain National Park » Reroutes and Repairs to Flood Damaged Trails » Document List

The National Park Service (NPS) is preparing to reroute and repair several trails in Rocky Mountain National Park that were damaged during heavy rains and subsequent flooding in September 2013.

The purpose of the project is to reestablish trail access on five damaged trails in four areas, while protecting natural and cultural resources and preserving wilderness character. Damaged trails that will be rerouted or repaired are: Alluvial Fan, Lawn Lake, Ypsilon Lake, Twin Sisters, and Aspen Brook. All of these trails currently remain open to the public except the Alluvial Fan Trail. Two separate decisions have been made to reroute and repair the trails. A decision to reroute and repair the Lawn Lake, Ypsilon Lake, and Alluvial Fan trails was made on June 24, 2016. A decision to repair and/or reroute the Aspen Brook and Twin Sisters trails was made on March 24, 2017.

An Environmental Assessment (EA) was prepared in compliance with the National Environmental Policy Act (NEPA) to provide a decision-making framework that 1) analyzed a reasonable range of alternatives to meet project objectives, 2) evaluated issues and impacts on park resources and values, and 3) identified mitigation measures to lessen the degree or extent of these impacts.

The EA was available for public review and comment from March 23 - April 29, 2016.
