Master Stormwater Management Plan

History & Background

Major flood events in 1982 and 1987, and changing floodplain regulations, prompted the Village to create a comprehensive plan to address flooding in Northbrook. In 1993, the first Master Stormwater Management Plan was approved and looked at causes of flooding, property protection programs, and projects to improve flooding conditions. As a result of the first edition of the Master Stormwater Management Plan, the Village instituted the 50/50 Private Property Drainage Improvement Program as well as the construction of the Techny Drain Water Shed basin, the Dell Road detention basin, and Underwriters Laboratory Tributary project.


Recent Updates

Since that initial plan was drafted it has been updated three times. The first update came in 1996 and the second came in 2002. These 2 updated editions included updated costs and reflected projects that been completed as well as any conditions that may have changed. The two editions included projects that have been completed including the Underwriters Tributary and initial phases of the Techny Drain project. The two editions also recommended projects such as the rear yard drainage program and the overhead sewer program.

The third and most recent update of the Master Stormwater Management Plan was completed in the fall of 2011. The projects, programs, and recommendations included in the plan were created around the Village's 4 goals for managing stormwater, the MSMP will not eliminate flooding in the Village. The goals of the 2011 Master Stormwater Management Plan in order of priority are:
  1. Reduce structure flooding/damage as a result of stormwater.
  2. Reduce street and front yard flooding to maintain access for emergency responders.
  3. Manage property flooding (rear and side yard).
  4. Manage development/redevelopment.

Master Stormwater Management Plan (MSMP)


The Village of Northbrook has completed the fourth revision of its MSMP. The plan is comprised of two documents: an executive report and a separate appendix that provides in depth history and analysis on stormwater in the Village of Northbrook and detailed information on the projects included in the plan. The projects, programs, and recommendations included in the plan were created around the Village's four goals for managing stormwater. The MSMP will not eliminate flooding in the Village.
