Water Conservation

Water conservation is the least expensive source of water that we have because a gallon saved is a gallon that does not need to be imported or produced. We all need to do our part to use water as efficiently as possible, so this vital resource remains readily available, now and in the future.

Water-saving practices cost little to nothing to implement and the water and financial savings can be substantial. SGVMWD offers numerous programs and resources to help you conserve!

Conservation Lifestyle

After California’s historic, five-year drought that ended in 2015, the Governor issued an executive order prohibiting water waste and calling on all residents to “make conservation a California way of life.” The order resulted in a statewide plan enacting long-term conservation measures and water use targets for urban water systems.

SGVMWD supports water conservation by partnering with our member cities to provide funding and technical assistance for water-efficient technology and equipment, infrastructure programs, and public education. Since 2010, the District has been committed to funding and creating a variety of water conservation pilot projects throughout the service area. These projects are taking place in each of our member cities and involve elements of water-efficient technology and equipment, water-wise and California Native plants, and in-school curriculum.

2021 Drought Update

With the San Gabriel Valley experiencing a very dry winter in 2021, coupled with declining state and local water supplies, it’s sounding a lot like it did in 2014, when the Valley’s last major drought period began. That drought period lasted about 5 years and a historic low groundwater level of 169.4 feet above mean sea level was recorded at the Baldwin Park Key Well on November 18, 2019. That’s a very significant reading since groundwater comprises about 80 percent of the water we use in the San Gabriel Valley.

After relatively wet years in 2019 and 2020, drought conditions have returned and are worsening.

Some researchers believe the last drought never ended and that the region is actually more than two decades into an emerging “mega-drought,” a hydrological event that is on par with the worst dry spells of the past millennium. Due to our dry conditions, droughts are a part of life here. We are either in drought, recovering from drought or preparing for the next drought. And, droughts are getting more extreme.

As pointed out in the District’s 2021 Earth Day public education ad many of our key indicators – local rainfall, groundwater, reservoirs, snowfall and imported water deliveries – are all trending downward. The combined effect is a “perfect storm” for our declining water supplies.

Drought is common, drought is normal and drought will recur…“it takes a long time to get into a drought and a long time to get out of a drought.” Fortunately, conservation works and is the most efficient and least expensive means of preserving our water supply.

We know you have questions about the drought…and the Valley’s water supply…and water conservation…and more. We’ve listened to you and have answers for you in an easy-to-read “Frequently Asked Questions” (FAQ) format. We provide questions and answers about a) drought in general, b) present drought conditions; c) the basics of our water supply in the San Gabriel Valley, and d) an introduction to the District’s water conservation programs. In addition, we provide links to the preeminent source of drought and water supply information in the San Gabriel Valley, “The Waters That Connect Us” website, sponsored by the Main San Gabriel Valley Watermaster (www.watermaster.org).

Ensuring a safe and sustainable water supply in the San Gabriel Valley is the District’s mission and is critical to our health, environment and economy. We hope we can help you learn as much about our water resource as you do about other public policy issues such as education, transportation, health care, public safety, energy and foreign affairs. As residents will increasingly vote on important water policy matters at federal, state, county and municipal levels, we will try to keep you informed and engaged in the water dialogue.

Overview of Drought

Wikipedia defines drought as an extended period when a region notes a deficiency in its water supply whether surface or underground water. A drought can last for months or years, and occurs when a region receives consistently below average precipitation. Intense drought can cause significant damage to the environment, public health and the local economy (e.g. local fire danger, mudslides, etc.).

According to the California Department of Water Resources, when drought occurs is a function of drought impacts to water users. Drought is a condition of water shortage for a particular user in a particular location. Hydrologic conditions constituting a drought for water users in one location may not constitute a drought for water users in a different part of California or for users with a different water supply. Although persistent drought may be characterized as an emergency, it differs from typical emergency events. Droughts occur slowly, over a period of time. Droughts impacts increase with the length of a drought, as carry-over supplies in reservoirs are depleted and water levels in groundwater basins decline.

The most significant statewide droughts occurred during 1928-34, 1976-77, 1987-92, and 2007-09. Southern California has experienced five major droughts since 1969 as shown on the graph below. A significant regional drought occurred in parts of Southern California in 1999-2002, and from 2014-2019. Looking back further, ring records from thousands of trees across western North America, analyzed to reconstruct soil moisture over the last 1,200 years, suggest that 2000-2018 was the second-driest period, eclipsed only by a mega-drought in the late 1500s.

The graph below shows our unpredictable weather conditions: 2/3 of the years show below average rainfall, meaning we tend to have a few very yet years followed by a larger number of very dry years. Drought is normal in southern California and the San Gabriel Valley. Dought will recur over time and is tending to be worse and more extreme due to climate change.

A very illustrative graph of Basin water levels and drought conditions since 2000 may be found on Watermaster’s educational website, “The Waters That Connect Us,” at https://www.thewatersthatconnectus.com/copy-of-challenges.

California got less rain in 2013 than in any year since it became a state in 1850. Storage in key state reservoirs was lower than in 1977, one of the two previous driest water years on record, and the state’s snowpack was less than 25% of average. The year 2014 began with a drought emergency declaration from Governor Brown on January 17, the first such declaration since Governor Schwarzenegger declared a drought emergency in 2009. And, that was followed by an announcement from the California Department of Water Resources on January 31, 2014 that the State Water Project was suspending water deliveries. This meant no replenishment water for our groundwater supplies in the San Gabriel Valley. As many of us in the San Gabriel Valley will remember, on January 15, 2015, Governor Brown mandated water-use restrictions statewide, leading to restrictions in our cities and county and a goal of 25 percent water conservation.

Such a declaration helps focus the public’s attention on drought conditions. In 2014, and again today, people everywhere in California pay more attention to water conditions. Newspapers, TV and radio news, and the internet “overflow” with news of drought and what to do about it. Conferences “spring” up in response and many government, business and community organizations have water on their agenda. Residents and businesses want to help out by saving water. Drought helps create conditions where legislative and political leaders take action on water-related legislation, infrastructure and funding.

Absolutely not! Sporadic rain and snowfall events, while helpful in boosting reservoir storage levels, often do not produce enough water to ease a drought. Sustained drought conditions and extreme heat lead to very dry surface conditions, evaporation of surface water and very thirsty vegetation. Those conditions may decrease the amount of precipitation or storm run-off which makes its way to groundwater levels that can be anywhere from 50-450 feet below the surface. It takes time and sustained water availability for run-off to percolate or seep down those long distances to aquifers and groundwater storage areas to end a drought.

Because the San Gabriel Valley Municipal Water District and other water agencies throughout the Valley have employed sound water management practices for several decades, and because the Valley has reduced consumption in recent years through water conservation, the Valley is not in immediate jeopardy of major water shortages. We do have water in reserve. Some people believe in the adage that “we will not run out of water, but we will run out of cheap water.” To a degree, we are protected by larger regional water storage facilities and a reduction in water demand resulting from effective water conservation efforts.

For cities served by the San Gabriel Valley Municipal Water District, we have been preparing for water shortages like this, effectively providing you with “water insurance.” In other words, as residents in our service area use water from local wells, we’ve been actively helping to refill or replenish the groundwater that supplies those wells with imported water delivered via the State Water Project.

The worsening drought (2021) means less water is available in the Valley and in the local mountains to help supply our local groundwater system, and the recent reduction (2021) of water deliveries via the State Water Project means we have less water available to replenish those groundwater supplies. Thus, our water insurance is declining – reservoir levels are lower, groundwater levels are lower, snow packs throughout local and regional mountain ranges are lower.

The drought results from a “triple threat” lack of precipitation in the following geographic areas:

  • San Gabriel Mountains which feed local wells and water supplies
  • Sierra Nevada Mountains which feed the Owens River, the L.A. Aqueduct, Northern California, the Sacramento-San Joaquin River Delta and the State Water Project/California Aqueduct
  • Western U.S. and the Rocky Mountains which feed the Colorado River.

Present Drought Conditions : Spring 2021

Unlike 2014, when Governor Brown declared a statewide drought emergency, Governor Newsom has not issued a drought emergency statewide. He has issued a statewide drought proclamation and a drought emergency in 41 of the state’s 58 counties. Nor have mandatory statewide water-use restrictions, such as those imposed in April 2015, been enacted. However, state officials, such as Karla Nemeth, Director of the California Department of Water Resources, stated in early 2021, “There is no doubt California is in a critically dry year. State agencies, water suppliers and Californians are more prepared than ever to adapt to dry conditions and meet the challenges ahead. California gets most of its annual precipitation from a handful of major and infrequent winter storms, which have become even more unpredictable as a result of climate change.”

The U.S. Drought Monitor graphs below illustrate how drought conditions vary over time and how conditions have worsened at the outset of 2021.

The State Water Project is the State’s largest water project and brings water from the State’s wet northern region to 25 million residents and 750,000 acres of farmland via the California Aqueduct. Late each year, the State prepares preliminary plans for the amount of water (Allocations) that will be made available the following year to State Water Contractors and other water agencies via the State Water Project. Those plans are sometimes modified in the ensuing months based on rain, snow and existing hydrological conditions.

As shown on the graph below, given the dry winter, in April 2021, the State announced it was reducing planned Allocations from 10 percent to five percent. That means less water from northern California will be provided to state water contractors such as the San Gabriel Valley Municipal Water District (serving the cities of Alhambra, Azusa, Monterey Park or Sierra Madre) or the Metropolitan Water District of Southern California, which also serves parts of the San Gabriel Valley.

SGVMWD’s full allocation of imported water is 28,800 acre-feet, thus, only 1,440 AF are available in 2021. The elimination of this imported water, used largely to replenish underground water supplies, will put increased demand and stress on our local wells, reservoirs and other water supplies. Thus, the amount of water in local wells will decline faster than when water deliveries are taking place.

It’s impossible to predict with specificity other than to know historically dry periods tend to last for several years or more. Climate change and extreme weather conditions, such as intense storms and intense heat, add to the uncertainty facing water managers.

That remains to be seen. While increased water conservation is called for now on a voluntary basis, individual cities or counties may impose mandatory water use restrictions or price increases at any time based on their particular needs. It’s important for residents and businesses to follow local water decisions that may impact them closely.

No one can say for sure what will happen to water pricing, but, long-term, water prices are likely to rise, as in most supply and demand scenarios. Scarcer supplies put upward pressure on the cost of water to businesses, residents and agriculture. We are already witnessing that within the San Gabriel Valley. Remember, water prices to residential and business customers are usually set by municipal water utilities or local water companies. The San Gabriel Valley Municipal Water District is a wholesale water agency and does not deal directly with end users.

The single, most important activity we can all do is save water and voluntarily reduce usage. Again, no one can say for sure what will happen, but long-term, if the drought persists and worsens, it is likely many local jurisdictions will impose mandatory use restrictions. Rationing is a more extreme measure and, if it happens, will be more on a case by case basis. It is possible the State would take action, as well.

Local municipalities and unincorporated areas may act independent of the State, on a jurisdiction by jurisdiction basis, to implement mandatory water conservation, water use restrictions, rationing, price increases, tiered pricing structures and other measures. Many communities will grapple with declining water levels in local wells. Some cities may impose tighter water conservation regulations and higher prices than others. Residents should follow local water developments at the city, county, regional and state levels. The San Gabriel Valley Municipal Water District has no control over the policies, pricing and actions of these local government entities.

Each city is different, but most have the ability to provide customer service and conservation information and/or audits. We suggest you either call the water utility in your city or visit their websites:

Water conservation works. During the most recent drought, cities in the San Gabriel Valley reduced water use by more than 25 percent, though demand has increased since that time. Water savings may be achieved through water-efficient technology, equipment and vegetation, as well as greater public education efforts. Whatever your motivation to save water: to help your family, to help your community, to help the environment, to save money…now is the time to get informed about ways to conserve and other relatively untapped water supply solutions such as recycled water, storm water capture and desalination.

You may attend your city council and board of supervisors meetings and pay attention to state and local government action related to water. Because most water is provided to you via local water districts, water utilities or water companies, you should monitor their actions closely for information. Another suggestion is to prepare for disasters which could further stress our fragile water supplies.

Any crisis or emergency has the positive benefit of increasing awareness, prompting action and inspiring creativity and innovation. New legislation and technology related to water supply and water quality receives increased attention, funding and support during drought periods. Presently, California is considering a variety of water-related initiatives such as the Delta Conveyance Plan which would make imported water deliveries more reliable.

Water Supply Basics in the San Gabriel Valley

First, let’s review the basics about the San Gabriel Valley’s water supply. Our water supply system includes a variety of sources of water including groundwater replenishment, imported water, reservoirs and cyclic storage, recycled water, storm water capture, and water transfers. Thus, despite developments such as record-breaking dry weather, worsening drought conditions, reduction of imported water deliveries via the State Water Project, and implementation of voluntary water use restrictions, the San Gabriel Valley has water in reserve to meet local needs for the near future, even if the drought continues.

However, it is a reality that local water supplies are lower than we would like. Another reality is individual cities, counties, the state and water companies may act to impose mandatory water-use restrictions and raise water rates/pricing to curtail water use. These are actions that the San Gabriel Valley Municipal Water District has no control over but that we encourage residents and businesses to follow in the towns in which their homes and businesses are located.

The San Gabriel Valley is a distinct watershed shaped by local mountains, rivers, streams and other geological formations. A major, natural source of water for the Valley is the San Gabriel River and streams, ponds, lakes, dams and reservoirs connected to it that are located either in the San Gabriel Mountains or the Valley, itself. Beneath the Valley is the Main San Gabriel Basin, the focal point of our Valley’s water supply system.

Your water basin is bit more than 100 yards below the ground, right underneath your feet, and it is situated throughout the Valley. Just imagine the length of a soccer or football field, but downward, deep underground. That’s where the vast majority of your water comes from. It is held in a natural holding area formed of bedrock called a water basin. This underground basin holds rainfall, snowmelt and conserved water.

By far the largest component of local water supplies is groundwater pumping, providing about 80% of the water we use. 20% of the water we use is imported water from northern California by the State Water Project and from the Colorado River.

For more information on the Valley’s water supply, please refer to Watermaster’s educational website, “The Waters That Connect Us” (https://www.thewatersthatconnectus.com/copy-of-the-basics).


Here in Southern California and the San Gabriel Valley we live in a dry, desert region. We use more water than Mother Nature provides. Supplemental sources of water (other than pumping of local aquifers or underground wells), include surface reservoir production, recycled water, storm water capture and supplies imported through wheeling arrangements or transported via aqueduct from the State Water Project and the Colorado River. When needed, the basin holds waters we purchase from “imported” sources, such as the Bay Delta in Northern California and the Colorado River. Importing water is expensive and requires energy to pump it hundreds of miles. However, sometimes these imported waters are needed when rain, snowmelt and conservation aren’t enough to sustain healthy water levels in our basin. Imported water is used to fill spreading grounds which allows water to percolate or seep down to replenish groundwater.

The San Gabriel Valley Municipal Water District, formed in 1959, was created to provide a reliable supply of supplemental water for its member agencies, namely the cities of Alhambra, Azusa, Monterey Park and Sierra Madre. The District is one of 29 State Water Contractors which import water from the State Water Project (the District utilizes its Devil Canyon-Azusa Pipeline for this purpose).

Given the size and topography of the San Gabriel Valley, it’s not surprising that groundwater levels throughout the Valley vary from location to location – it is true that different locations in the Valley have more water or more accessible water than others. And, some wells in the San Gabriel Valley are polluted or contaminated. Water rights and pumping rights are complicated – for example, Monterey Park relies on water that is pumped from wells located in Rosemead. Thus, in 1973 the Main San Gabriel Basin Watermaster was created to manage and protect groundwater resources within the Main San Gabriel Groundwater Basin. The San Gabriel Valley Municipal Water District works very closely with Watermaster and other water agencies located in the San Gabriel Valley.

A widely accepted measure of our local groundwater supplies is the Baldwin Park Key Well. As the diagram below shows, groundwater levels have longer periods of decline than of ascent given that most of our years are relatively dry, with the historic low level of 169.4 recorded in November 2019. The graph also displays the critical importance of cyclical storage: the black line indicating groundwater levels without storage and the higher, blue line indicating groundwater levels with cyclic storage factored in. Note that cyclic storage levels have increased since the last drought due to smart water management practices throughout the Main San Gabriel Basin.

The City of Azusa draws its water primarily from Main San Gabriel Basin wells located in Azusa adjacent to spreading grounds which are located at the terminus of the pipeline operated by the San Gabriel Valley Municipal Water District. The City supplements this source of water with water from the San Gabriel River. Whenever the City’s groundwater production exceeds its water rights, untreated imported water is delivered to the San Gabriel Basin via the pipeline operated by the San Gabriel Valley Municipal Water District to replace that amount of water which was produced in excess of the City’s water rights. Water is treated, pumped to and stored in reservoirs located in the City, and then transported via the City’s water distribution system to your tap.

Sierra Madre’s groundwater historically came primarily from wells in the Raymond Basin and from surface water that is transported via tunnels reaching into the San Gabriel Mountains. In the recent past, Sierra Madre was 100 percent reliant on its Metropolitan Water District connection due to low groundwater levels in its local wells. In 2019 the San Gabriel Valley Municipal Water District and the City of Sierra Madre worked together to identify a long-term solution to the challenges facing the City and the District. That led to a water wheeling agreement between Sierra Madre and Arcadia that also called for construction of a joint well to be located within the City of Arcadia. The water would then be transmitted through Arcadia’s existing pipelines to Sierra Madre’s water distribution system. In January 2020, the District approved nearly $1.9 million in grant funding to begin construction of the joint well.

Monterey Park’s water comes primarily from San Gabriel Basin wells located in neighboring Rosemead. Whenever the City’s groundwater production exceeds its water rights, untreated imported water is delivered to the San Gabriel Basin via the pipeline operated by the San Gabriel Valley Municipal Water District to replace that amount of water which was produced in excess of the City’s water rights. Water is treated, pumped to and stored in reservoirs located in the City, and then transported via the City’s water distribution system to your tap.

The City of Alhambra’s water supply is primarily groundwater pumped from a portion of the Main San Gabriel Basin which is referred to as the “The Alhambra Pumping Hole.” The City supplements this source of water with a direct connection to the Metropolitan Water District’s pipeline. Whenever the City’s groundwater production exceeds its water rights, untreated imported water is delivered to the San Gabriel Basin via the pipeline operated by the San Gabriel Valley Municipal Water District to replace that amount of water which was produced in excess of the City’s water rights. Water is treated, pumped to and stored in reservoirs located in the City, and then transported via the City’s water distribution system to your tap.

Water Conservation

The District supports water conservation for both environmental and economic reasons. Water conservation is the easiest, most efficient and least expensive means of dealing with the drought. Every drop of water you save is a purchase you don’t need to make. Every drop of water we save is water that remains in our groundwater basin, aquifer and wells. Every drop of water we save is water we don’t need to import, recycle or treat.

Water Conservation means different things to different people. For some, it means equipment or processes, such as water timers and water-efficient appliances. For others, it means human behavior, such as the length of our showers, whether we install water efficient appliances, if we leave the faucet running while we brush our teeth, or if we use a hose, rather than a broom, to clean our driveways.

The Water District supports water conservation in many ways. The Conservation section of our website provides much more information on the District’s water conservation initiatives. A principle advanced by the District’s Board more than a decade ago was to develop a strong focus on educating, informing and motivating young people about water conservation. The Board believed then and now that if young people acquire water conservation and sustainability ethics, they will hold them for a lifetime and be a positive influence on their parents, families and communities.

Several other informative and educational conservation-oriented websites are:

For more than a decade the District has worked closely with school districts to provide hands-on presentations and materials to encourage development of sustainable water and environmental attitudes and behavior.

  • Our “Home Water Survey” enables students to work with family members and friends at home to identify water saving opportunities. (cannot find it on the website…provide link to location on website)
  • The “Our Precious Water Resource” video is available on-demand on our website for use in school or at home (https://www.youtube.com/channel/UCoGv1lxSIg1HzzQ8ix3_hAw/featured)
  • Our “Water Awareness Growth Chart” is available on our website for download or you may contact the district to have one mailed to your home or school (626-969-7911; info@sgvmwd.com).

Under the banner of the H2Owl Outreach Program and our Speakers Bureau Program, District representatives are available to speak to schools and community and business organizations on water-related topics. We also provide tours of District facilities on a planned and requested basis. For further information or to request assistance, please contact the District (626-969-7911; info@sgvmwd.com)

Our strategy has been to implement pilot projects at highly visible, high water-consumption locations and to create partnerships with member cities and community organizations to make the pilot projects as well known as possible. Beginning in 2009, the District began offering grants for water conservation pilot projects to cities, schools and large employers. The Water District has provided approximately $12 million in grants to fund more than 25 water conservation pilot projects in our four member cities. Our goal has been to both save water and to provide information to help residents, schools, businesses and other organizations adopt water saving technology, materials and procedures for the long-term.

As “demonstration” projects, our pilot projects take place in highly visible community locations that are easy to visit and learn from. Our grants funded equipment, technology, landscaping and vegetation and promote indoor and outdoor water savings. An added objective of each grant is to foster community partnerships that involve people working together. Projects at schools and youth or community facilities typically involve youth, teachers, parents, local businesses, local non-profits, churches and school clubs. Case studies can be viewed at (http://sgvmwd.com/CONSERVATION/pilot-projects).

The District’s O.W.L. Community Grant Program (Opportunities for Water Leadership) provides grants ranging from a few hundred dollars to $2,000. Eligible recipients include schools, clubs and community and business organizations. Funds are available on a rolling basis and the District has funded several dozen projects since the Program’s inception. For more information about or to apply for a grant from the OWL Grant Program, please visit our website at http://sgvmwd.com/EDUCATION/OWL_PROGRAM.

The District offers an extensive rebate program whereby stakeholders who purchase water saving appliances and equipment save water and save money. Items in the District’s rebate program include: rain barrels and cisterns, water-efficient washing machines, high-efficiency toilets, “smart” and weather-based irrigation controllers, soil moisture sensors, rotating sprinkler nozzles and commercial waterless urinals. For more information or to apply for a rebate, please visit our website section devoted to rebates http://sgvmwd.com/CONSERVATION/Rebates.

Our website provides water saving tips in multiple languages for residents, businesses and multi-family dwellings such as apartment buildings. Please visit our website at http://sgvmwd.com/CONSERVATION/WaterSavingTips. In addition, the District has created a variety of educational videos which may be viewed on our website at http://sgvmwd.com/video.


More than 50% of water use occurs outdoors and that provides an abundance of opportunities for saving water. Water-wise plants and landscaping are among the smartest and most effective means of reducing outdoor water use. Over many decades, as people have relocated to southern California and the San Gabriel Valley from other parts of the country, they have tended to landscape like they did back home. The reality is we live in an arid desert and we use more water than Mother Nature provides. Fortunately, for those with a certain aesthetic and those who love to garden, there are plants that are “native” to southern California and the San Gabriel Valley. They will survive in our warm, dry climate, they are attractive, they use less water and they are readily available.

Different terms to describe such vegetation include “California Native Plants”, water-efficient plants and drought-tolerant plants. Water-efficient landscaping may also include rock gardens, boulders, benches, synthetic turf and other decorative elements that use no water at all.

Saving water at home

Conservation doesn’t have to be hard! Even the smallest changes at home can add up to big savings.


Water efficiency on the job

No matter your business, you can save as much as 50 gallons of water a day by switching to rebate-eligible appliances and fixtures at the office. And by enlisting your staff to employ water-saving practices, that can add up to thousands of gallons (and dollars) per year!


Gardening Guide

Did you know that water-wise gardening practices can cut your water use by half and still keep your landscaping green and healthy? 

Here are some tips for getting started:

– Observe the pattern of runoff in your yard when it rains. You can create berms, swales and other contours to slow the flow and catch the water so it can be used by your plants.

– Use drip systems, soaker hoses and other efficient irrigation methods that apply water close to the plant roots. Keep in mind that plants adapted to dry summers need less water a few years after planting.

– Add compost or mulch to the soil. Compost helps the soil hold water and adds nutrients needed for plant growth. Mulch prevents the soil from overheating and drying out, reduces weeds and slows erosion. Use 2 to 4 inches underneath plants and shrubs.

– Gather rainwater in buckets and save it for later use in your garden.

– Avoid over pruning or forcing plants to grow into unnatural shapes.

– Layer plants to make shade and use species that are native to the area.

– Observe the natural shade and sun of your yard and plan your garden accordingly.

Water Conservation & Water Quality Pilot Projects

SGVMWD invests in water conservation pilot and demonstration projects in our member cities and provides zero-interest loans and grants to encourage customers, schools, businesses and organizations to adopt long-term water saving technology, materials and practices.

Some of the work funded since 2009 includes the installation of California native plants, drip irrigation and smart controllers at public buildings and in street medians. 

The Water District is working with its member cities to develop pilot and demonstration programs that emphasize water-wise landscaping and water-efficient gardening equipment and techniques. As these projects get finalized and produce results, we look forward to sharing more information with you.

Native Plants

The California Native Plant Society website is a very helpful guide to selecting water-wise vegetation appropriate for specific geographic locations and micro-climates. When you visit their website (www.calscape.org), you may enter your address or click on a map of California to identify your location. Then, a comprehensive listing (including pictures, descriptions and planting and care guides) of plants that will thrive in your area are highlighted.

The District has also supported the Theodore Payne Foundation in a variety of ways over the years to provide information about “water-wise” California Native Plants to teachers, students, residents and businesses. For more information about California Native Plants please visit the Theodore Payne Foundation website.
