Project Overview#
The Oak Street project is part of the Downtown Stormwater Improvement Program (DSIP) and will help to resolve flooding issues in downtown Fort Collins. The project extends from Mason St. to City Park and began at Mason Street in July 2024.
Additionally and in preparation for the stormwater project, the City will be replacing the water main from Grant Avenue to Jackson Avenue, and Xcel Energy will be replacing the gas main from Meldrum Street to Jackson Avenue.
The map below shows the general locations and projected timeline for the projects.
Stormwater Project: June 11 Update#
Ongoing#
- Howes/Canyon: rain garden work ongoing through June. There is a smaller closure for ongoing construction in this area.
- 500 and 600 Block Oak Street: Irrigation and Landscape Repairs (coordination with property owners)
- Loomis intersection: storm pipe installation ongoing; storm structures and inlets ongoing
- Oak and Grant intersection: curb and gutter work; dewatering system and material storage located here
Upcoming#
- 100 S Block Meldrum: mill and overlay asphalt, late June
- 600 Block: Asphalt Paving operations and striping, late June
- 700 Block Oak Street: storm pipe installation
- 100-300 S Blocks of Loomis: Asphalt Overlay (July)
Important Notices#
- The permitted parking zones on the 200 S and 300 S blocks of Loomis, and the 600 W and 700 W blocks of Olive have been relaxed due to the various project closures in the area to allow residents more street parking options.
- At the Oak/Loomis intersection area, there will be two other construction projects happening concurrently with this project. There will be a sanitary sewer replacement project on Loomis from Mountain to Oak Street, from April 28 to late May. There will also be a storm sewer replacement project on Loomis from Oak to Olive, from early May to early July. Residents most impacted by this work will receive flyers at their door that will provide more details.
- It is now "flood season", which, for the project, means that the project team must be prepared for a flood event at any time. As part of being prepared, City Code requires construction projects to store equipment and materials outside of the designated floodway from April 1 through October 31. This is why you see a larger closure on Whitcomb and Sherwood, to allow us to store items outside of the floodway along Oak Street. Visit fcgov.com/flooding to stay informed about flooding events.

Estimated Construction Timeline#
FAQ#
-
There will be full roadway closures on Oak Street and other adjoining blocks where pipeline construction is occurring. Residents with alley access to their lots will be encouraged to utilize the alleyways as much as possible when the roadway is closed on their block. Residents that don’t have alley access will need to park on adjacent blocks. Sidewalk access to property frontage will generally remain open or detours for pedestrians will also be posted.
-
Sidewalk access to business property frontage will generally remain open. There will be some intersection and crosswalks closed during streetscape construction. During those times, detours for pedestrians will be posted.
-
You can expect large construction operations, including heavy equipment, dirt hauling and associated noise and dust during the construction period.
-
Stormwater system improvements include flood control measures as well as stormwater quality improvements such as rain gardens at Howes, Washington and Jackson. Rain gardens are systems that filter pollutants out of stormwater before it makes its way downstream to the Poudre River. As such, significant streetscape improvements to these same intersections will be made.
Other improvements being made as part of the Oak Street project include a new water main from Grant to Jackson Street, and a new gas main (Xcel Energy project) from Meldrum to Jackson Street.
-
On-street parking will not be available on the blocks where active construction is occurring. Generally, the construction zone will be limited to 2 or 3 blocks at a time and automobile detours will be posted to reroute drivers.
-
While we do anticipate ongoing construction adjacent to City Park during the summer months, we don’t anticipate a large impact on any events at City Park during those times. There will be reduced on-street parking near the Oak/Jackson intersection and along Jackson north of Oak Street, but existing parking will generally be available otherwise.
-
Yes, water services may be shut off for short periods of time (4 hours or less) during active construction of the water or storm mains. We will let you know at least 24 hours in advance of any shut-off.
-
Yes, its possible that either gas or electricity may be shut off for short periods of time during active construction.
