Winthrop Comprehensive Plan

Winthrop, MN | Public Works

Overview

The City of Winthrop, Minnesota enlisted ISG’s stormwater management experts to investigate where flooding occurs, to what extent, and how to alleviate it. A stormwater plan was constructed by ISG to manage the flooding.


Opportunity

Insufficient stormwater management within the City of Winthrop created severe flooding over urban topography, causing concerns for City residents and employees during storm events.

Solution

A stormwater management plan was constructed using surveys from previous streets projects, and stormwater run-off was calculated by simulating a 100-year rainfall event, using a city-wide 2D hydraulic and hydrologic model, XPSWMM’s Rain-on-Grid. The findings from the simulation were confirmed by testimonials from residents and City employees with first-hand knowledge of the problem areas. The plan proposed cost-effective methods of improving conveyance and increasing storage, to alleviate flooding. Improvement areas were prioritized based on concerns of City employees, extent of flood damage, cost-effectiveness, and the timeline for future streets projects.
