North Trail Extension

The work to be performed is the complete construction of new, natural surface, non-motorized bike and pedestrian path. The total length of the project is approximately 13,066 feet, and includes the creation and grading of a 12-15 foot-wide trail along this entire length. The path surface will be finished with 4-inch-thick road base that would be topped with a 2-inch-thick layer of gray crusher fines. Redi-rock retaining walls will be used below the Ordinary High Water Mark (OHWM) of the Animas River to retain the trail and prevent bank erosion in the reach identified in the “Construction Plans for Animas River Trail North Extension”. The trail extension will also include creating a pedestrian walkway under the Browning Parkway Bridge where approximately 180 feet of concrete pathway would be constructed. Concrete would be cast in place and a gabion retaining wall would be built at this location to prevent erosion during high flow events. Three prefabricated bridges would be installed over irrigation ditches and waterways in the project area. Total disturbance would be approximately 4.5 acres; 4.446 acres of permanent impacts to uplands, .02 acre of permanent impact to a forested wetland, and .034 acre of permanent impact to the Animas River. A check dam will be constructed for work below the OHWM and will result in 0.08 acre of temporary impact to the Animas River.
