In response to recommendations in the Stormwater Master Plan approved in 1996 and wide spread flooding that occurred in Northbrook after storms in September of 2008, the Village Board authorized two programs to help residents with private property flooding issues. Under these programs, the Village will reimburse residents for up to 50% of the costs to complete improvements to their property to help minimize the chance or severity of future flooding. These programs include the 50/50 Overhead Sanitary Sewer Program and the 50/50 Property Drainage Program.

50/50 Overhead Sanitary Sewer Cost Participation Program

Offered on a first-come first-serve basis, the Overhead Sanitary Sewer Cost Participation Program helps property owners protect their home from sewer backups during intense wet weather conditions.

Program Process & Eligibility Requirements

Step 1: Contact the Development & Planning Services Department at 847-664-4050 to schedule an eligibility inspection at the property. Minimal requirements for the program include: 1) Home constructed prior to 1965, 2) Seeking to convert from gravity system to overhead system. For information regarding eligibility requirements, please view the Overhead Sanitary Sewer Conversion Program Information.

Step 2: If you are eligible to participate in the program, you must complete and submit a program application along with the necessary submittals (see below) to the Development and Planning Services Department.

Step 3: Once a program application is received, it is reviewed and a permit will be issued.

Step 4: Schedule and complete a Rough Plumbing Inspection.

Step 5: Schedule a Final Inspection once work is completed.

Step 6: Once a Final Inspection is passed, property owner must pay all outstanding invoices to the Contractor; and submits a notarized Final Waiver of Lien/Contractor’s Affidavit and an IRS Form W-9 to the Village.

Step 7: Once paperwork is received, the reimbursement payment will be distributed within thirty (30) days.

Application Fees & Deposits

  • Building Construction & Inspection Fees - $130 (Due at time of permit pick-up)
  • Additional fees may apply at time of permit pick-up

Important Reimbursement Information

Reimbursement by the Village for pre-qualified program participants will be processed only upon completion of the work. The Village’s contribution will be limited to only 50% of the actual contractor construction cost, up to a maximum of $5,000, necessary to convert the plumbing system to an overhead sanitary sewer system. If the property owner selects a plumbing firm other than the lowest responsible bid, then the Village’s contribution will be limited to 50% of the lowest bid amount, up to a maximum of $5,000.

Additionally, once a building permit is approved, the property owner will have ninety (90) days to commence the overhead sanitary sewer conversion work. If work does not commence within this time frame, the home owner will forfeit its eligibility for any reimbursement. Lastly, if the property is demolished within five (5) years following the date of reimbursement by the Village for its share of the cost participation funds, a refund by the property owner shall be required. The property owner’s refund shall be 100% of the Village’s cost participation funds within one year of repayment, 80% for the second year, 60% for the third year, 40% for the fourth year, and 20% for the fifth year.


Private Property Cost Share Drainage Program

Residents experiencing overland, rear, side, or front yard flooding can help protect their homes and alleviate ponding or standing water in their yards by making improvements to their property that may include but not be limited to: re-grading their yards, installing swales, berms, rain gardens, or a number of other options. Residents with flooding conditions that qualify for this program will be reimbursed for a share of the improvement cost, up to $5,000 subject to funding availability. Village contribution for cost share drainage projects will be up to 30% for projects involving drain and/or pipe infrastructure, and Village contribution will be up to 70% for natural solutions including but not limited to swales and rain gardens. As is the case with the 50/50 Overhead Sewer Conversion program, residents are reminded that a permit and inspection of this work is required regardless of whether or not a property owner is participating in this 50/50 program.

Residents wishing to participate in the program can view the Drainage Program Cost Reimbursement Application and the Village’s Drainage Protection Cost Program Standard Operating Procedure.

The Village may cover up to $175 in cost of acquiring and planting a tree. Residents wanting more information can contact the Public Works Department via the GONorthbrook Service Request system.
