Arlington Heights FAQ
Do I need a grading permit for landscaping work?
A grading permit is required if your landscaping work involves fill, excavation, or changes to existing drainage patterns. Minor landscaping that does not alter grading or drainage does not typically require a permit.
Can my neighbor redirect water onto my property?
No. The Village requires that all grading maintain existing drainage patterns and not redirect water onto adjacent properties. If a neighbor's grading work is causing drainage problems on your property, contact Engineering at (847) 368-5800.
When is an engineered retaining wall required?
Retaining walls over 4 feet in height require engineering design by a licensed professional engineer and a building permit. Walls under 4 feet generally do not need engineering but must still comply with setback and drainage requirements.
Skokie FAQ
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.
