From The City of Grand Prairie:
Hard Freeze warning; Monday 11:55 AM - Tuesday 10:00 AM
Just a friendly reminder regarding irrigation systems—please shut down sprinkler systems for the next several days since the temperature is expected to drop below freezing this weekend.
Ice on Streets. A city ordinance makes it a violation to allow water from an irrigation system or water system to collect on city streets on cold nights when it can form ice and cause hazards to unsuspecting drivers. The ordinance is designed to encourage residents and businesses to be considerate during very cold weather. A resident or business (or PID or HOA) that allows significant ice patches to form on city streets should be prepared to face fines.
