(A) Identify programs. The city shall coordinate with local water purveyors and identify programs that enhance and encourage landscape water use efficiency such as tiered water rate structures; allocation-based conservation water pricing structure; a rate structure at least as effective as the above options; irrigation audits and/or irrigation surveys; and penalties for water waste.
(B) Restrictions. The following water conservation requirements are intended to avoid water waste, are effective at all times, and are permanent.
(1) Limits on watering hours. Watering or irrigating of lawn, landscape or other vegetated area with potable water is prohibited between the hours of 9:00 a.m. and 5:00 p.m. on any day, except by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self-closing water shut-off nozzle or device, or for very short periods of time for the express purpose of adjusting or repairing an irrigation system. Overhead irrigation shall be limited to the hours of 8:00 pm to 9:00 am.
(2) No excessive water flow or runoff. Watering or irrigating of any lawn, landscape or other vegetated area in a manner that causes or allows excessive water flow or runoff onto an adjoining sidewalk, driveway, street, alley, gutter or ditch is prohibited.
(3) No washing down hard or paved surfaces. Washing down hard or paved surfaces, including but not limited to sidewalks, walkways, driveways, parking areas, tennis courts, patios or alleys, is prohibited except when necessary to alleviate safety or sanitary hazards, and then only by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self-closing water shut-off device, a low-volume, high-pressure cleaning machine equipped to recycle any water used, or a low-volume high-pressure water broom.
(4) Obligation to fix leaks, breaks or malfunctions. Excessive use, loss or escape of water through breaks, leaks or other malfunctions in the water user's plumbing or distribution system for any period of time after such escape of water should have reasonably been discovered and corrected and in no event more than seven days, is prohibited.
(C) Landscape meter requirements.
(1) A separate dedicated meter is required for landscape areas greater than or equal to 2,500 square feet.
(2) The efficient use of water should be considered in the design of any new landscape area. The MAWA will be calculated for customers that request a new account using the formula in § 15.04.050(B)(12)(m) of this chapter.
(3) Prior to the issuance of a meter, the new customer shall calculate the EAWU for each landscape area using the formula provided in § 15.04.050(B)(12)(n). The EAWU shall be submitted to the local water purveyor for review. For the new meter to be issued, the calculated water budget for the landscape area cannot exceed the MAWA calculated in § 15.04.050(B)(12)(m) of this chapter.
(4) New accounts that have to comply with equivalent or more stringent water use efficiency measures imposed by another jurisdiction, do not need to comply with the requirements of this section of the chapter, but do need to provide information about the landscape area to the local water purveyor.
(D) Enforcement. The restrictions set out in this section first shall be enforced by the water purveyor; in the event the water purveyor does not do so, or requests the city to do so, they may be enforced by the city by any legally available means.
