Post-flood restoration work is underway along the St. Vrain Creek between US 36 and Airport Road, also referred to as Reach 3.
Reach 3 is located east of Lyons and west of Longmont. The approximate project boundaries are US-36 to the west, Ute Highway (SH-66) to the north, N. 75th St. to the east, and Hygiene Road to the south. The area was severely damaged by the September 2013 floods due to many streambank breaches and concentrated flow in areas of the floodplain.
Along 1.5 miles of creek the following work will be done by American Civil Constructors Mountain West Division:
- Repair four of the nine stream breaches (1, 2, 6, and 7a, see map) to reduce the risk of future catastrophic failure
- Remove the metal and concrete debris left behind by the flood
- In select areas, restore, grade, and shape the channel to minimize future erosion
- Restore riparian vegetation to areas stripped bare by the flood
Please note: while this project is in the area of the proposed gravel mining operation along the St. Vrain Creek, it is not a gravel mining project.
