Project Status Update
Week of August 12, 2019
The contractor will be working on the 12-inch Town of Lyons waterline in unincorporated Boulder County this week and Monday and Tuesday of next week. Work is anticipated to remain in the construction zone for the next two weeks.
A pipeline construction zone of 500 feet will be closed to traffic except for emergency vehicles. Residents living within the construction zone will have access to their driveways. Residents that are EAST of the current dig area (where the pipe is being installed) may access their property from the south intersection of Apple Valley Road and US36. Owners should work with the flaggers to access their properties.
- Access to Apple Valley Road will remain open at the intersection of US 36 and the north end of Apple Valley Road.
- Access to Antelope Road is available from the north side of Apple Valley Road at US 36.
The City of Longmont and Town of Lyons will relocate their existing water lines from the North St. Vrain Creek corridor to Apple Valley Road beginning in spring 2019. This relocation is expected to continue through fall/winter 2019.
Both pipelines are used to provide drinking water to Lyons and residents along Apple Valley Road.
The relocations will reduce the risk of damage and loss of water service from future natural disasters, including floods.
Longmont and Lyons are coordinating the water line relocations to minimize impacts to residents in Apple Valley.
Goals and Proposed Improvements
Lyons will relocate a 12-inch water line; Longmont will relocate a 24-inch water line.
The water lines will be relocated to provide greater protection from natural disasters and allow better access to the pipelines for future operations and maintenance. Currently, the existing pipelines are within the floodplain or floodway of the North St. Vrain Creek and run along or cross the creek. Pipeline access in most cases requires crossing private property.
The new pipeline locations will be installed within the Apple Valley Road right-of-way with the majority of the pipelines situated outside of the floodplain. The image shows the location of the Longmont water line. The Lyons water line will begin at Apple Valley Road and Antelope Road and end at Apple Valley Road and US 36.

The two water line projects are scheduled to begin construction in June 2019 and continue throughout most of 2019.
During construction, most activity will occur within a 500-foot construction zone that will be closed to all traffic except emergency vehicles. At the end of each work day, the road will reopen to two-way traffic.
Work hours will initially be from 8:00 am to 7:00pm within Boulder County jurisdiction and 7:00 am to 7:00 pm in the Town of Lyons jurisdiction. The City of Longmont and Town of Lyons will coordinate the two projects whenever possible to minimize the impact to residents.
Both pipelines were affected by the 2013 Flood and will receive federal funding for their relocations.
