The St. Johns River Water Management District’s permanent watering restrictions are designed to ensure the efficient use of water for landscape irrigation. The restrictions allow enough water to maintain healthy landscapes year-round.

“Landscape irrigation” means the outside watering of plants in a landscape such as shrubbery, trees, lawns, grass, ground covers, plants, vines, gardens and other such flora that are situated in such diverse locations as residential areas, public, commercial and industrial establishments, and public medians and right-of way. “Landscape irrigation” does not include agricultural crops, nursery plants, cemeteries, golf course greens, tees, fairways, primary roughs, and vegetation associated with intensive recreational areas, such as playgrounds, football, baseball and soccer fields.

Summary of the restrictions

  • During daylight saving time irrigation is limited to no more than two days per week on scheduled days.

Exceptions to the restrictions

Watering in of chemicals may not exceed ¼ inch of water per application except as otherwise required by law, the manufacturer, or best management practices.
  • Irrigation systems may be operated anytime for maintenance and repair purposes, not to exceed 20 minutes per hour per zone.
  • Irrigation using a hand-held hose equipped with a spray nozzle that can be adjusted so water flows only as needed is allowed anytime.
  • Discharge of water from a water-to-air air-conditioning unit or other water-dependent cooling system is not limited.
