Drought

Best practices for all residents and businesses: (Please note HOA's and businesses have additional guidelines. Please see Homeowner’s Associations and Commercial Properties section below)

1. Limit watering of lawns, landscape, and turf areas to no more than 2 days per week and no more than 15 minutes of watering per day per station or irrigation zone.
   • Commercial properties and HOA's must not water all decorative grass.
2. Do not water outside plants or landscaping within 48 hours after significant rainfall.
3. Adjust outdoor watering systems to avoid runoff onto non-landscaped areas (walkways, roads, parking lots, or structures).
4. Do not use water to clean driveways or sidewalks, instead use a broom.
5. Wash your car at a commercial facility that recirculates the water.
6. Do not use water in a water feature, except where the water is part of a recirculating system or needed to sustain aquatic life in lakes/ponds.
7. Check for hidden leaks by reading your water meter when all devices are off.
8. Fix leaks or broken plumbing features as soon as possible or within 72 hours after noticing issue.

New California Law as of June 10, 2022

Owners and managers of non-residential property, including homeowner’s associations, commercial and institutional facilities, must meet the following requirements:

• Commercial, industrial, and institutional decorative grass should not be watered
• Turn off decorative water fountains
• Give all trees just what they need: avoid overwatering
• Follow the local requirements of your water supplier (see best practices above)
• Turn off/pause your irrigation system when it’s raining and for two days after rain
• Use an automatic shutoff nozzle on your water hose
• Use a broom, not water, to clean sidewalks and driveways

Violation of these requirements is now considered an infraction under State Law. The water suppliers or local government may choose to enforce the regulations with a fine of up to five hundred dollars for each day in which the irrigation of non-functional turf occurs.

There is financial assistance available to convert these spaces to drought tolerant landscaping. Commercial and HOA properties can apply to save $3.00 per square foot for the first 10,000 square feet and $2.00 per square foot thereafter and more. Visit WaterSavings.org view all your rebate options.

The City of Cupertino organization plans to achieve the 15 percent savings goal. Based on the current restrictions imposed by Valley Water, City Municipal Operations are currently at Stage 4 of water conservation measures, which means the City will follow the guidelines such as:

• Reduce water programming for all outside irrigation for trees/shrubs, having them be at a minimum according to the conservation amount.
• No watering of turf used passively.
• Limited watering (consistent with two days/week watering or similar) of turf areas used intermittingly at City permitted events.
• A minimum of 20 percent reduced watering of turf areas by City or school recreation events.
• No filling of ponds at Memorial Park.
• No operation of the interactive fountain at Community Hall.
• No water used to clean asphalt areas/sidewalks/plaza areas.
• Water used for street sweeping to be minimized while complying with Santa Clara Valley Air Board requirements.

Community Garden

• Gardeners have been provided information about the conservation requirements and tips on best practices for watering.
• Drip line use has been encouraged. Master Gardeners have held a workshop to teach gardeners how to install drip lines and coordinated efforts with some retailers to provide them a discount on supplies.

Blackberry Farm Golf Course

• Phase 1: stop watering the rough areas
• Phase 2: stop watering the fairways
  • 2a: 50 yards in front of the tee boxes
  • 2b: 100 yards in front of the tee boxes

The City has a long history of conserving water across its operations, leading by example through its practices, and encouraging businesses, residents and schools to do the same.

During the 2015 drought, staff developed and implemented water conservation restriction measures for City operations and made amendments to the Municipal Code Chapter 15.32 to allow the City to further conserve water.. Through City’s actions, the City was able to achieve a cumulative savings that is 31 percent below the 2013 consumption baseline.

Additionally, the City provided additional incentives to residents that participated in the landscape rebate program. . From 2010 through 2020, there were a total of 339 rebates processed with 457,569 square feet of landscape converted to drought-tolerant plantings. These projects resulted in permanent conservation of approximately 9.2 million gallons of water every year. As shown in the following table, the number of residents and businesses participating in the landscape conversion program increased during 2015 and 2016, when the City started offering additional incentives.
