Long Prairie council adopts stormwater resiliency study to guide future street projects
Summary
Council approved a grant-funded Stormwater Infrastructure Resiliency Study that maps high-flood areas, estimates a 100-year rainfall event at 4.5 inches over 24 hours, and recommends inlets, upsized pipes and bypass areas for future street projects.
The Long Prairie City Council voted April 9 to approve a Stormwater Infrastructure Resiliency Study funded by a grant. The study identifies potentially high-flooding areas and recommends infrastructure changes, including added inlets, upsizing pipes and constructing bypass areas where warranted.
Council members said the study's findings will be incorporated into the city's future street improvement projects and submitted for grant reimbursement. The study notes that a 100-year storm could produce an estimated 4.5 inches of rain in 24 hours, a planning figure council members cited when discussing priority locations for upgrades.
