Portsmouth lawns are big and open, and its water district has imposed odd/even watering before. One local crew handles weekly mowing, spring and fall cleanups and planting across Portsmouth, from Island Park to the farms in the middle of town, with the schedule in writing.

Portsmouth has some of the largest residential lots in the area: farmhouse lawns, long frontage along East and West Main Roads, waterfront grass on the Sakonnet and Narragansett Bay, and tighter cottage yards at Island Park.
Most of Portsmouth is on the Portsmouth Water and Fire District, which has used odd/even watering days with fines in dry summers; a small part of town is on Newport Water. Irrigation should be set to match.
