The El Campo City Inspections Department has already sent out more than 30 letters this month warning property owners to start your mowers or get ready for the bills. City staff typically mow during off hours, costing a property owner about $100 for a residential type lot, more for larger parcels. A certified letter and a standard letter are sent out at the same time. Once sent, there’s a 10-day requirement for compliance. El Campo lawns have received almost 10 inches of rain in the last 30 days, according to the dayta from the Lower Colorado River Authority gauge on the El Campo Memorial Hospital grounds.
