Grading & Drainage: Des Plaines vs Skokie

Can my downspout drain onto my neighbor's lot?

No. Concentrated stormwater discharge directly onto an adjacent property is prohibited. Discharge to splash blocks on your own property, drywells, or storm sewer connections is appropriate.

Can I connect my sump pump to the sanitary sewer?

No. Sump pump and downspout connections to the sanitary sewer are prohibited and contribute to combined sewer overflows. They must discharge above grade or to the storm sewer.

Do I need a grading plan to replace concrete?

Minor flatwork replacement maintaining existing grades typically does not require a grading plan, but new additions or significant grading changes do require plan review by Engineering.

Do I need a permit to regrade my yard?

Major grading, retaining wall construction, or projects that change drainage patterns may require a permit. Minor landscaping without altered drainage typically does not. Contact Community Development before significant projects.

My neighbor's drainage is flooding my yard. What can I do?

Report to Skokie Public Works at (847) 933-8427. The Village can investigate whether modifications violate drainage rules. Civil remedies are also available through private legal action.

Where should my sump pump discharge?

To your own property, ideally toward the street, alley, or storm inlet. It may not connect to the sanitary sewer, and the discharge cannot be concentrated onto neighboring property.
