Morningside Flood Infrastructure Project

Join us 5-6:30 p.m. on December 9th to hear about the new revised concept, ask questions, and give us your reaction. The livestream video link will be available under the 'Virtual Meetings' tab.

A recording of the video and a copy of the presentation will be posted after the meeting.

The City will host a third virtual public meeting with residents from 5-6:30 p.m. on December 9th.

We've come up with a new revised concept that maximizes the flood risk reduction benefit.

Join us to learn more and tell us what you think.

Provide your reactions and ideas for the flood infrastructure scenarios under the Ideas tab. We'll use what we learn from you to come up with a single preferred option that we'll share with you at Virtual Meeting #3 on December 9th.

Join us to review alternatives, share your opinions, and get answers to your questions.

1-3 p.m. Saturday, October 31.

Or, you can take the virtual tour here.

What is the problem?

• "What is My Flood Risk?" interactive map - explore the risk for a specific property as well as across the neighborhood.
• Flood Risk Reduction Project video (3 mins) - introduction to the general flooding problem and what the project is about.

• Flood Risk Reduction Project video #2 (5 mins) - a closer look at the flooding issues.

What options are being considered?

• Download an overview of the scenarios we've explored. If you're looking for a deep-dive into the material, you can read the technical memo that the overview is based on.

How do I participate?

• Join us for a socially distanced Halloween pop-up in Weber Park from 1-3 p.m. to review the scenarios and talk with staff.
• Share your reactions and ideas on the Ideas Tab.
• Call or email a staff person.

Join us to learn more about alternatives for reducing flood risk, share your opinions, and get answers to your questions. Oh, and candy.

Landlocked basins do not have low level outlets; the only way for water to leave is through evaporation, infiltration, transpiration, and/or pumping. Because there is no outlet structure, landlocked basins are prone to high water levels during wet years and can hold water long after a storm ends.

When making decisions about adding storm sewer outlets to these basins, we must consider downstream impacts and the trade-offs of transferring flood risk. We use 2-dimensional stormwater models to test infrastructure options so that we can understand how flood exposure changes, where the benefits accrue, and where and when options cause impacts.

This map shows landlocked basins and areas that drain to landlocked basins in the neighborhood.

Before it was developed as a residential neighborhood in the mid-1900s, the Morningside neighborhood was largely a low-lying wet area, with a county ditch running right through it. The original plan for County Ditch 17 was part of the Minnesota History Museum collection from the bygone Hennepin County Soil and Water Conservation District. The Minnehaha Creek Watershed District is the current county ditch authority.

Here's a photo of the original plan and a modern map with the former ditch location drawn in. This 1908 survey map with modern streets overlaid shows the location of historical wetlands throughout the City.

Check out this topographic relief map to see the highest and lowest areas in the neighborhood.

Weber Park is the low area in the neighborhood. Water from the north and south portions of the neighborhood generally flow toward 41st corridor and 42nd street. Upon reaching the 41st corridor and 42nd street, water moves east to Weber Pond. Water leaves Weber Pond through a storm sewer pipe to the north toward Bde Maka Ska in Minneapolis.
