  • NWO-2020-02061-DEN

    Expiration date: 3/5/2022

    The City of Thornton is proposing to replace the York Street bridge over Big Dry Creek and modify the channel along 2,549 linear feet of Big Dry Creek. The channel modifications include realignment, reshaping, and bank and channel stabilization to create a multistage channel to convey flows. The existing York Street bridge will be replaced with a 200-foot-long bridge and the road will be reconstructed to 50 feet wide. Lastly, a portion of the Big Dry Creek Regional trail will be constructed at the northern portion of the bridge. The project, as proposed, would impact 2,549 linear feet (0.71-acre) of Big Dry Creek, 0.82-acre of adjacent wetlands, and 0.08-acre of open water.
