Summary
Crystal Lake and McHenry County have no ordinance specifically banning or approving residential artificial turf. Installations must still meet Unified Development Ordinance landscaping and setback standards, and large impervious projects trigger McHenry County's stormwater permit thresholds.
Any development that results in an additional 5,000 square feet of impervious area from the original effective date of this Ordinance; or, Any development which hydrologically disturbs 5,000 square feet or more;
Full Breakdown
No Crystal Lake or McHenry County code section directly regulates synthetic/artificial turf in residential yards - the county sets no specific rule here, so your city's UDO landscape standards govern. Practically, artificial turf still has to comply with UDO landscaping, drainage, and setback requirements, and it may not be counted toward required living-landscape or open-space minimums. Large hardscape or impervious installations can activate the McHenry County Stormwater Management Ordinance, which regulates any development adding 5,000 square feet of impervious area or hydrologically disturbing 5,000 square feet, requiring a stormwater permit and runoff controls.
Violations & Fines
Turf itself is not separately penalized, but installations that add impervious area past the county's 5,000-square-foot threshold without a stormwater permit, or that violate drainage/setback standards, are enforced under the UDO and Stormwater Ordinance.
