Skokie's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Skokie, Illinois, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Stormwater Management

Skokie is subject to the Cook County Watershed Management Ordinance (WMO) administered by the Metropolitan Water Reclamation District of Greater Chicago (MWRD), which regulates development-related stormwater volume, detention, and water quality. The Village also maintains local sewer and grading rules. Development over 1/2 acre of new or redevelopment impervious area triggers full WMO review.

Key details: Regulator: MWRD / Cook County WMO. WMO Trigger: 0.5 acre impervious. Watershed: North Branch Chicago River. Illicit Discharge: Prohibited. Sanitary Sewer: No downspout/sump connection.

Illicit discharges to the storm sewer are subject to MWRD and Village penalties, typically beginning at $250 per occurrence. Altering lot drainage to flood neighboring property may result in Village notice to correct and fines from $75 per day. Major WMO violations on development projects may require costly retrofit. Contact Public Works at (847) 933-8427.

Grading & Drainage

Skokie requires that lot drainage be managed so that stormwater flows to public streets, alleys, or storm sewers and does not adversely affect neighboring properties. Grading plans are reviewed by Public Works and Community Development for new construction, additions, and major landscaping projects. Alterations that redirect water onto neighbors violate the municipal code.

Key details: Positive Drainage: Away from structures. Neighbor Drainage: Cannot redirect harmfully. Downspouts: Not to sanitary sewer. Retaining Walls: Engineered over 4 ft. Minimum Slope: 2% from foundation.

Altering drainage to harm neighbors may result in a code enforcement notice with fines from $75 per day and an order to restore original drainage. Major grading without required permits can result in stop-work orders and double permit fees. Contact Public Works at (847) 933-8427 or Code Enforcement at (847) 933-8284.

Flood Zones

Skokie participates in the National Flood Insurance Program and enforces floodplain development regulations under its municipal code consistent with 44 CFR and the Illinois Rivers, Lakes, and Streams Act. Most of Skokie lies outside mapped FEMA Special Flood Hazard Areas, but portions along the North Shore Channel and historic drainage corridors include flood-prone areas. The Village participates in the FEMA Community Rating System.

Key details: NFIP Participant: Yes. Freeboard: +1 ft above BFE. Main SFHA: North Shore Channel area. Urban Flooding: Sewer-driven events common. Substantial Improvement: 50% threshold.

Unpermitted floodplain development is a serious violation with fines from $250 per day and potential FEMA sanctions on the Village if left uncorrected. Building below base flood elevation may make the structure ineligible for affordable flood insurance. Contact Community Development at (847) 933-8447 before any floodplain-area construction.

Erosion Control

Erosion and sediment control on Skokie construction sites is governed by the Cook County Watershed Management Ordinance and the Illinois Environmental Protection Agency's construction general permit for sites disturbing 1 acre or more. Skokie Public Works enforces local grading and erosion rules for smaller sites and requires silt fencing and inlet protection on active construction.

Key details: IEPA Permit: 1+ acre disturbance. Silt Fencing: Required. Inlet Protection: Required. Stabilization: Within 14 days typical. Tracking: Must be cleaned promptly.

Erosion control violations can result in stop-work orders and fines beginning at $150 per day. IEPA may separately pursue NPDES violations with penalties up to $50,000 per day for major discharges. MWRD may issue violation notices under the WMO. Contact Public Works at (847) 933-8427 or Code Enforcement at (847) 933-8284.

The Bottom Line

Skokie's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Skokie is broadly strict or permissive.

Keep in mind that Skokie can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
