Stormwater Projects

Stormwater projects can vary from dry well installation, maintenance, and cleaning to levee maintenance. This page provides information on projects scheduled for 2021.

We will provide regular updates here on our Projects page and on Facebook as schedules are finalized. For more information, email Tracy Campbell or call (406) 552-6364.

Maintenance Work on Levee III and Levee V — Completed

Description:  This project involves removal of all non-native vegetation, cottonwoods, and any trees or shrubs ≥4 inches in diameter at chest height from the levee prism and within 15 feet of the riverward side of the floodwall on the north side of the Clark Fork River. Small woody debris will also be removed, while cut trucks (except golden willow) ≥10 inches in diameter shall be retained on site. Native shrubs <4 inches in diameter at chest height will be retained to provide shelter and food for wildlife, as well as to provide shade and mitigate the effects of reflective heat from the riprap.

Storm Water Utility staff collaborated with the City's Parks and Recreation Department to identify the non-native vegetation. They also consulted Montana Fish, Wildlife, and Parks to obtain the necessary permit. The Clark Fork River will not be disturbed during this work.

The utility has contracted with a local company to perform this work, as required by the U.S. Army Corps of Engineers to maintain the integrity of both Levee III (Madison St. to Orange St.) and Levee V (California St. to Russell St.). Engineers from the Army Corps will be inspecting the levees in the near future, and the levees could also lose their accreditation if not properly maintained. Non-accreditation of the levees would cause all businesses and residences protected by the levees to either obtain or increase their flood insurance.

Project Dates:  Scheduled to begin March 1, 2021, with completion expected around April 15. These dates are subject to change due to weather and other unforeseen circumstances.

Trail Closure Information:

  • The North Riverfront Trail adjacent to the active work area will be closed weekdays 9 a.m. to 4 p.m.
  • Work will start at the Madison Street Bridge and move to the west in 3- to 5-day increments with sections closed at approximately the following locations and order:
    1. Madison Street Bridge to just east of Kiwanis Park.
    2. Along Kiwanis Park to the east end of Bess Reed Park.

    5. From the California Street Bridge to the Russell Street Bridge.
  • Once work is completed on a section, the trail will be reopened.

Detour Maps:

Due to construction downtown and winter road conditions, a prearranged detour route has not been defined. Cyclists and pedestrians are advised to use parks, streets, and sidewalks as needed to travel around the trail closures. Closures will be timed to avoid peak commuter traffic times. Please plan for a few extra minutes of travel time during the project.
