Know the designated days
The St. Johns River Water Management District’s 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. The mandatory restrictions specify the time when watering may occur, the amount of water that may be applied, and the days when watering may occur for residential and nonresidential locations. These days depend on whether the address ends in an odd or even number, and on the time of year.
“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 rights-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.
“Residential landscape irrigation” means the irrigation of landscape associated with any housing unit having sanitary and kitchen facilities designed to accommodate one or more residents, including multiple housing units and mobile homes.
“Nonresidential landscape irrigation” means the irrigation of landscape not included with the definition of “residential landscape irrigation,” such as that associated with public, commercial and industrial property, including commercial or transient housing units, hotel and motel units, and public medians and rights-of-way.
