Council adopts Sauk Creek Corridor plan with amendment to favor naturebased bank treatments

The Common Council adopted the Sauk Creek Corridor conceptual plan on March 11, endorsing a high-level framework for roughly 1.1 miles of greenway and stormwater-related work. City engineers described the plan as a starting point for more detailed engineering and permitting; the council added a final whereas clause directing that design phases "minimize riprap bank stabilization and use more environmentally sensitive nature-based solutions where feasible." The amended plan was adopted by unanimous vote.

Why it matters: Sauk Creek drains into downstream ponds and waterways; staff said conceptual planning is intended to narrow options, surface tradeoffs and prepare for detailed engineering, permitting and budgeting. City engineering staff emphasized that the conceptual plan combines technical stormwater modeling, field assessment and public input to create a pathway to later design phases.

Public comment and technical input: Dr. Faith Fitzpatrick, a professional hydrologist and geologist, spoke in opposition to the conceptual plan as presented to the Board of Public Works and suggested the plan should show how proposed measures will improve channel stability, reduce erosion and address long-term geomorphic responses. Dr. Fitzpatrick offered examples of bioengineering alternatives that are already in use by municipal stormwater programs and volunteered to serve on technical advisory work as detailed design proceeds. City engineers said the conceptual plan can accommodate further technical review and that the plan'to-design process will include additional community and expert input.

Council amendment and rationale: Alder Conklin offered an amendment (a new whereas clause) asking staff to minimize riprap and favor nature-based bank stabilization techniques during design phases. City project manager Jojo O'Brien described "bioengineering" options (vegetation, soil lifts, tree reinforcements) and said the public'proposed preference for riprap during earlier input reflected a desire to minimize disturbance; staff said the plan allows room to evaluate alternatives and refine solutions during design.

Outcome: The council adopted the Sauk Creek Corridor plan as amended; staff said subsequent phases will include more detailed engineering designs, permitting steps, potential archaeological reviews and cost estimates. Engineers noted the plan was developed with extensive public engagement and roughly 3,000 staff engineering hours to date.

Ending: Engineers and interested experts will move into detailed design and permitting; staff said they will include community and technical advisory input as the design work proceeds.
