Our goal is to follow best irrigation practices while also conserving our water. We monitor the weather regularly and shut off irrigation systems when indicated by the weather forecast and anticipated rain accumulation.
- It is the City's goal to maintain and enhance native habitats, conserve water and to enrich residents' enjoyment of the greenways and nature areas. Learn more about standards used in greenway maintenance by visiting our Park Maintenance webpage.

Discover Longmont's many, diverse parks and trails through our Directory of Parks & Trails.
The paved greenways and trails represent Longmont's transportation network for bicycles and pedestrians. Unpaved paths generally go into City open space and the more natural areas where it is our goal to minimize maintenance and disturbances to wildlife. These areas include unpaved paths around McIntosh Lake, Golden Ponds, and the Jim Hamm Nature Area to name a few. We also don't mow along most of those paths for the same reason, to maintain habitat and minimize disturbances.
It should be noted that plowing unpaved trails is also not a maintenance best-practice. Plowing before freezing damages the trail, and plowing after snow hardens requires heavier equipment with ballast. Not only is that a much more expensive operation, it also has the potential to damage the trail.
For details about what paths we do plow and how they fall in the Parks Snow & Ice Control Plan, visit our Parks Snow Plan webpage.
Overall, the rule is based on State Health Department requirements because water quality monitoring is not conducted at any park water body, except Union Reservoir. In addition, there are also varying reasons why certain water bodies do not allow swimming. For example, in the case of Lake McIntosh, the City does not own this lake, but holds a recreational lease with the ditch company which allows certain activities.
Visit Recreation Services to find more information on a variety of swimming options - both indoor and out - available in Longmont.
Park restrooms close each October in advance of winter’s frost to prevent damage to the above-ground plumbing, which is not designed to withstand winter temperatures. The City places portable toilets in several high traffic areas for use throughout the winter. These facilities are cleaned and stocked once per week from November to April.
For more information, visit the Parks Public Restroom webpage.
- Yes, metal detecting is permitted in our public parks, however no digging is allowed.
- There are many ways citizens can become involved including participating in public meetings to help develop parks, contributing time and/or money, gifting, or simply enjoying our natural areas. To learn more about specific opportunities, please visit our Get Involved webpage or contact Parks, Open Space and Trails.
- Spray water features are generally turned on beginning Memorial Day weekend. They operate daily from 8 am – 8 pm until October 15. To find a list of parks with spray water features, visit our Directory of Parks and select the amenity: spray water feature.
- All recreational activity and use information related to this reservoir can be found on the Union Reservoir Park webpage.
Resilient St. Vrain Project
- 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.

This extensive, multi-year 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.

Work is progressing from downstream to upstream. Learn more on the Resilient St. Vrain Areas of Work & Schedule webpage.
Construction is well underway on the Resilient St. Vrain project. Visit the Areas of Work & Schedule webpage for details.
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.

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.
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.
Learn more on the Resilient St. Vrain Funding webpage.
- 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.
