7/14/2021 Update:
A new "Frequently Asked Questions" document is available.
City staff compiled the information after the June 30, 2021 Public Information Meeting to respond to several questions about the proposed solutions on erosion in City greenways and.or scouring at the harbor/outfall.

Project Overview

The City of Madison will complete a watershed study in the Spring Harbor watershed (as shown below). The watershed study will identify causes of existing flooding and then look at potential solutions to try to reduce flooding. The study will use computer models to assist with the evaluations. A local engineering consultant, Advanced Engineering and Environmental, will complete the study.For more information please see the Flash Flooding Story MapView a new story map for this watershed! Story maps are interactive pages that explain a project more visually and interactively. Take a scroll through this new tool to understand the Spring Harbor Watershed Study. *Note: Please view the story map using Firefox or Google Chrome browsers. Story maps are not viewable with Internet Explorer.

During the June 30, 2021 Spring Harbor Watershed Study Public Information Meeting attendees asked several questions about the effects of the proposed solutions on erosion in City greenways and/or scouring at the harbor/outfall. City staff compiled a Frequently Asked Questions document to answer these questions: Spring Harbor Outfall Repair and Dredge FAQ. PDF  For more information about the related projects, you can view the Spring Harbor Outfall Repair project and the Spring Harbor Dredge project webpages. 

Help the City understand what you want to prioritize flooding projects. Please take our survey and learn more about how we're working to prioritize stormwater improvement projects in our community.

Project Schedule

The watershed studies take 18-24 months to complete.  The first studies will take longer as the City works through the best processes and approaches for this new flood study initiative.

Public Involvement

There are a number of points of contact during this project where the public is encouraged to give feedback as part of public information meetings and public hearings. Dates and times are indicated below:

Public Information Meetings

Focus Group Meetings

In the summer and fall of 2019, the City of Madison Engineering Division hosted a variety of focus groups for known flooding areas within the watershed. 
Map of focus groups set in the spring harbor watershed. Areas include West Towne Pond, Oakwood village Association, Marbella Condo Association, Mineral Point Park to Owen Park, Regent St Burneet Dr & Calumet Cir, Owen Park Concrete Channel, Bordner Park, and the Spring Harbor Neighborhood Association.
The following focus group meetings occurred in this watershed: 

  • Mineral Point Park to Owen Park, 4-5 p.m., Aug. 28, Corner of Quarterdeck Dr and the bike path,  about 150 feet north of the intersection of Landfall Dr and Quarterdeck Dr on the east side of the street
  • Owen Park Concrete Channel, 6-7 p.m., Aug. 29, Corner of Forsythia Pl. and Bordner Drive
  • Regent Street, Burnett Drive and Calumet Circle, 4-5 p.m., Aug. 29, Corner of Burnett Drive and S. Kenosha Drive
  • Marbella Condo Association, 2-3 p.m., Aug. 30, Outside Marbella Tennis Court gates near corner of South Yellowstone Drive and Mineral Point Road
  • Oakwood Village Association, 2-3 p.m., Sept. 18, inside meeting room of Oakwood Village Center for Arts and Education
  • Bordner Park, 6-7 p.m., Sept. 19, Bordner Park Playground, 5600 Elder Place in center of park
  • West Towne Pond, 3-4 p.m., Sept. 16, Schwoegler Park Towne Lanes Banquet Hall, 444 Grand Canyon Drive
  • Spring Harbor Neighborhood Association, 5-6 p.m., Oct. 3, Spring Harbor Park Playground (corner of Spring Harbor Drive and Lake Mendota Drive)

Additionally, people within focus groups were involved in breakout sessions during the second public meeting on February 24, 2020. Residents were able to sit with engineering staff to provide feedback on where the drainage model predicted flooding during certain rain events.

Additional Resources

Report Flooding

If anyone has experienced flooding, and is willing to share with the City, please report it on the City's website. Even if a homeowner reported flooding to 2-1-1, FEMA, or a City official, the City needs standardized information to create stormwater models that show existing flooding conditions. The flood data helps the City prioritize different flood projects and future watershed studies. Please report any flooding you’ve experienced.
