The L.A. City Council today approved changes to the city's water conservation ordinance that limits when lawn watering can take place.

The revision comes in light of a report that concluded current conservation efforts caused a series of water main breaks last year.

The rules should be easy to follow, but they do need some explanation. Via the LADWP:

Under the revised Ordinance, customers whose street addresses end with an odd number - 1, 3, 5, 7 or 9 - will be permitted to use their sprinkler systems on Mondays, Wednesdays and Fridays, before 9 a.m. and after 4 p.m. Customers whose addresses end in even numbers - 0, 2, 4, 6, or 8 - will be permitted to do so on Tuesdays, Thursdays and Sundays, before 9 a.m. and after 4 p.m. Addresses ending in fractions will be treated as whole numbers and observe the same day restrictions as others on their same side of the street, (ie: 4321 ½ is regarded as 4321, an odd-numbered address.)
Sprinkler time limits will be based on the type of nozzle used. Spray head sprinklers and bubblers, which are non-conserving models and are common in most landscapes, will be limited to 8 minutes per cycle and one cycle per day per watering station. Rotors and multi-stream rotary heads will be allowed 15 minutes per cycle and up to two cycles per day per watering station.

Additionally, watering is only allowed before 9 a.m. and after 4 p.m., even if it's a household's watering day. Hand watering with garden hoses is allowed any day of the week within those time restrictions, but only if they are fitted with a shut-off nozzle.

The approved ordinance now heads to Mayor Antonio Villaraigosa for his signature. If signed, the revised law will go into effect upon publication about a week later.
