Where can I sign up to be notified if there is a flood or emergency event?
Be sure you sign up for the Longmont Reverse Emergency Notification System to receive real-time, emergency notification on devices beyond your traditional landline telephone. The system is utilized to notify our community if evacuation is needed. You will only receive notifications during an emergency. You can register cell phones, VoIP accounts and email accounts. The system is “geo-based,” which allows you to link your devices to your home address. If an evacuation is needed and your home address is included, you will be notified regardless of where you are (at work in Denver, out shopping, etc.).
Where can I find real-time info about river flows and view creek cameras?
Visit the Flood Preparedness and Safety webpage to learn what actions Longmont's Office of Emergency Management takes and how to stay connected in case of flooding in our community.
Is the City or County doing anything to fix the St. Vrain Creek channel?
Collaborative efforts are under way by both Boulder County and the City of Longmont to make the St. Vrain Creek capable of safely carrying up to 100-year flood flows. Learn more about Longmont's efforts on our Resilient St. Vrain webpages and find Boulder County's information on the St. Vrain Creek Master Plan.
Resilient St. Vrain Project
When will construction begin for Resilient St. Vrain?
Construction work began in November 2016 on the Sandstone Reach. February 2017 was the start date for City Reach 1, which runs from from Main Street to Left Hand Creek (east of Martin Street).
Among the main goals for the City’s construction work are to ensure the rebuilt sections of the creek channel and greenway trails are safe for the public to access and resilient to future flooding events.

What is Resilient St. Vrain?
Resilient St. Vrain is the City of Longmont’s extensive, multi-year undertaking to fully restore the St. Vrain Greenway trails and improve the St. Vrain Creek channel to protect people and property from future flooding. Without these improvements, vulnerable portions of our community remain at risk for flood damage.
Work on Resilient St. Vrain is divided into distinct sections, known as reaches. The portion of St. Vrain Creek that runs through the urban, more-developed areas of Longmont is known as the City Reach, while the more natural area to the east of town, which includes the Sandstone Ranch nature area, is called Sandstone Reach. Construction began in the Sandstone Ranch in November 2016 and in City Reach 1 (downstream of Main Street to where Left Hand Creek joins the St. Vrain) in February 2017. Work will move upstream as sections are completed.
How long will Resilient St. Vrain construction take?
Initial planning work began in 2014 for Resilient St. Vrain. This large-scale, long-term undertaking is anticipated to take 7-10 years to complete. Work will be completed in sections, moving upstream. The timeline includes periods for vegetation regrowth to protect natural habitat as sections are completed, as well as work to secure additional funding.
Construction began in the Sandstone Ranch area in November 2016 and in the City Reach section from Left Hand Creek to Main Street in February 2017.

St. Vrain Creek or St. Vrain River: Which is correct?
It's St. Vrain Creek. Geographical names are assigned by the U.S. Board on Geographic Names (part of the U.S. Geological Survey), which has designated the body of water that runs through Longmont as St. Vrain Creek. Learn more about how the geographic names program works here, or view the USGS feature detail report for St. Vrain Creek here. The creek begins at the confluence of the North and South St. Vrain Creeks in Lyons and flows east to join the South Platte River northwest of Platteville. Along the way, Left Hand Creek and Boulder Creek flow into the St. Vrain Creek as well.
How much will Resilient St. Vrain cost? Who is paying for the project?
The cost for work to rebuild the St. Vrain Greenway and to restore and revitalize the St. Vrain Creek channel is estimated between $120 million and $140 million. Partial project funding for Resilient St. Vrain is coming from a variety of sources.
$20 million in voter-approved Storm Drainage Bonds
Additional funding will come from a combination of existing City funds (including the 3/4-cent Street Fund tax), plus monies from Federal Emergency Management Agency, Federal Highway Administration, State, County and Community Development Block Grant-Disaster Recovery funding.
The City continues to seek grants and other funding possibilities to fully fund this long-term and extensive project to protect the community.

Why is Resilient St. Vrain being designed to meet 100-year flood flows?
Design plans for Resilient St. Vrain use 100-year flood flows and the 100-year floodplain as benchmarks. The Federal Emergency Management Agency (FEMA), state and local agencies use the 100-year floodplain in regulatory processes related to building permits and environmental regulations, as well as for setting flood insurance requirements and costs.
A major flood event in September 2013 severely impacted Longmont, especially along the St. Vrain Creek. This flooding affected many properties within and outside of the floodplain. A flood event of this magnitude had not been experienced in Longmont since 1894, and it served as a reminder that the risk of major flood events is real and ever-present. From the disaster comes the opportunity to protect the community while restoring the St. Vrain Creek channel and improving its resilience to future flooding.
