Whitefish Bay Storm Sewer Recovery

CLIENT: Village of Whitefish Bay, WI

What began as a sudden infrastructure failure in Buckley Park quickly escalated into a critical public safety emergency when a 54-inch storm sewer pipe, buried nearly 70 feet underground, collapsed. With heavy rainfall imminent and the risk of further collapse, the Village turned to Clark Dietz to deliver an immediate and effective response.

Clark Dietz rapidly mobilized alongside contractors and Village officials to stabilize the site and restore stormwater flow. Within five days, the team designed and implemented a temporary bypass system using more than 200 feet of 36-inch fused HDPE pipe and 360 feet of corrugated HDPE pipe, supported by dewatering systems and field-adapted solutions. This fast-tracked approach, informally dubbed “ratchet strap engineering,” successfully maintained system functionality and protected the surrounding community during subsequent storm events.

Beyond emergency response, Clark Dietz is leading the design of a permanent reconstruction solution estimated at $5 million to $6 million. The project includes installation of a new drop structure, earth retention system, and concrete pile-supported foundation, along with reconnection of key sewer infrastructure, outfall lining, and full restoration of Buckley Park.

This project demonstrates the importance of proactive infrastructure monitoring, rapid interagency coordination, and intentional temporary design under pressure. It stands as a strong example of engineering adaptability in the face of urgent and high-risk conditions.
