High Line Canal Stormwater Study 2022

The final report from the Stormwater Study is available here. The draft report was presented to City Council at the Study Session on Sept. 20th for review, and the final report was accepted by City Council at their meeting on Dec. 14th, 2022. 

For a summary of the study, please visit the project's StoryMap here. 

Background

In fall 2021, City Council  directed staff to seek further analysis of the High Line Canal Stormwater Master Plan (Master Plan) as it pertains directly to the three-mile segment of the Canal within the Village, as well as craft short and long-term strategies for capital improvements and annual maintenance of this segment of the High Line Canal. The Master Plan explores the analysis associated with utilizing the Canal for stormwater purposes but cannot be construed as acceptance or approval of the drainages analyzed or improvements recommended. The City desires to know what additional considerations are necessary to transition the City’s segment of the irrigation Canal to a stormwater channel and how to address certain considerations to accomplish that goal. 

Stormwater Capital Improvement and Operations Analysis

Icon Engineering, Inc. has been hired to complete the study in 2022 for a total cost of $59,000. The analysis will include modeling of High Line Canal areas beyond what was completed in the Master Plan to ensure safety, constructability, and ease of maintenance. Additionally, the City will receive a detailed cost model verifying the costs outlined in the Master Plan for the construction and maintenance of: (1) the proposed improvements; and (2) the entire High Line Canal conveyance channel, including the ditch and bank vegetation, within the municipal boundaries, as the City will become responsible for these costs if the stormwater improvements are constructed. Further, the analysis will give the City guidance on possible phasing and timing plans for the capital projects, based on prioritization determined during the analysis process.
