Single-Family Residential Impervious Surface Regulations

The Village Code contains Maximum Impervious Surface regulations for single-family residential properties in the Village. The Village Code (Section 6-2-2) defines impervious surface as "any man-made area that alters the natural surface course for, or does not allow for, the natural rate of absorption or retention of storm water." Such areas include, but are not limited to, building footprints, driveways, walkways, swimming pools, porches, decks and patios.

The goal of these regulations is twofold: to control stormwater runoff and to enhance neighborhood aesthetics. This is mainly accomplished through control of development intensity by placing limits on the amount of paved or other impervious surface area that can be present on any individual lot. By implementing the maximum impervious surface ratio, the Village strives to enhance its drainage system (and minimize Lincolnshire’s effect on the Des Plaines River watershed) and maintain the desired community character with ample green space and natural landscape.

The impervious surface ratio is obtained by dividing the total amount of all impervious surfaces on the lot by the total lot area. The maximum impervious ratio permitted by Code depends on the zoning district the property is located in. The requirements are as follows:
