Forty years of flooding, solved in thirteen months - a mile-long gravity relief system for the Town of Mukwonago.
Residents of the Country Bliss Subdivision had endured recurring flooding for 30 to 40 years - studied repeatedly, never solved. Sitting in a landlocked kettle basin, the neighborhood needed more than another report - the Town had been working toward a fix for over a decade. Lynch vetted solutions, designed and permitted the system, and had construction underway within a year of starting work with the Town.
The solution: a gravity pipeline storm sewer system spanning over one mile - a 12-inch ADS N-12 closed-system pipe, a 24-inch steel casing section that avoided intricate driveway headwalls at the community association building, and a weir-controlled discharge with an emergency shut-off valve to protect downstream properties. Lynch managed solution vetting, design, permitting, bidding, construction administration, and stakeholder coordination with the affected residents, delivering roughly 10% savings on overall project cost.
Keeping the road open was the point - for residents, and for the police, fire, and ambulance services that depend on it. An operations and maintenance plan handed the Town's public works department everything needed to keep the system performing for the long haul.
Over a mile of closed-system relief piping drains the landlocked kettle basin.
12-inch ADS N-12 pipe, 24-inch steel casing section, and weir-controlled outfall.
Solution vetting, design, permitting, bidding, and construction administration - one team.
Stakeholder coordination and disciplined administration beat the budget.
