Stormwater Drainage and Lake Level Study (2019-2020)

About the Study

The City of Burnsville, along with project consultants AE2S, completed a Stormwater System Modeling and Analysis Study. This study helped determine areas within Burnsville's storm sewer/drainage system that may need updating and helped identify potential problem areas.

Throughout the process, the City asked for public engagement and feedback to try to understand as many significant drainage issues as possible. However, staff is unable to directly respond to all issues. 

With questions, email City Engineer Jen Desrude or call 952-895-4544.

The study consisted of three phases and was completed in mid-2020, leading to the planning of a proposed improvement to be constructed in 2021.

Storm Sewer System Model

Comprehensive digital models of storm sewer systems help identify potential problem areas, and areas that are more prone to flooding. The City reviewed its previous models and made necessary updates.

High Flood Risk Review

Using the updated models, the City identified areas where flooding is likely to occur, and analyzed what risks are associated if no improvements are made to those areas. For the highest risk areas, the City will work to develop potential solutions and identify the costs for any future improvements. 

Lake Level Review

Using the updated models, the City studied the drainage system (map of lake flow at right) and all lake levels from Keller Lake north to the Minnesota River. Once the review was completed, the City determined there is an improvement that the city is planning on undertaking in 2021.
