San Diego’s Farmer of the Year Taps Every Drop

/in , /by

Growing water-intensive crops like avocados in San Diego County is no small feat. Producing avocados requires the use of innovative farming methods to supply the trees with enough water.

It’s the use of innovative farming methods that earned John Burr the title of San Diego County’s Farmer of the Year – an honor he recently celebrated on KUSI-TV with Water Authority Board Chair Jim Madaffer as part of the agency’s Brought to You by Water outreach and education program.

Innovative farming methods

Over the past few months, the Water Authority partnered with local agriculture industry leaders like the San Diego County Farm Bureau to highlight the importance of safe and reliable water supplies for more than 5,500 local farms that are part of the county’s $4.8 billion agriculture industry.

Local farmers like Burr are invaluable in growing the agricultural bounty that sustains 3.3 million residents and the region’s quality of life.

Found in everything from tacos to smoothies to toast, avocados have become a staple in California cuisine and, with only about 10 inches of annual rainfall in the San Diego region, it takes innovation and technology to grow the popular fruit.

Technology saves water

For decades, Burr has been perfecting the operations on his Escondido farm, using state-of-the-art technology like the California Irrigation Management Information System. Two different satellite systems allow him to regulate irrigation by zones to determine precise water amounts to prevent using too much or too little water on his trees.

Satellites collect data, which Burr then analyzes with spreadsheets to determine how many gallons of water each tree requires. Every bit of data collected, from water usage to atmospheric conditions to soil type, allows Burr and his team to streamline their operations to be even more water-efficient.

“In San Diego County, we have to get the most out of our crops with the least amount of water,” said Burr, who irrigates his farm with water from the City of Escondido. “When the weather varies with changing seasons or fluctuating weather patterns, providing the right amount of water at the right time is paramount to using water efficiently. These technologies provide the information and tools that allow us to do that consistently, and ensure our crops grow successfully.”

Efficient land use conserves water

Those who see Burr’s farm may also notice another difference from the typical avocado farm, which is that his groves are designed for high-density planting.

“A typical avocado grove can have about 100 trees, but ours have about 400 in the same area of land. This cuts our water usage in half,” he said.

Each tree is also limited in height to prevent water loss through transpiration. This is especially important in a region like San Diego County, where temperatures can rise quickly on summer days.

Tips for Responsible Lawn Maintenance

/in , /by

While the goal of many sustainable landscaping plans is to remove the traditional suburban lawn, sometimes a portion of lawn area is maintained.

You can ensure that your lawn stays healthy, permeable and green by using sustainable landscaping tips for lawn maintenance:

  • Grass cycling
  • Using proper mowing height and frequency
  • Eliminating chemical use
  • Monitoring watering frequency and duration
  • Using organic amendments, particularly compost

Turf should be top dressed with one-eighth to one-quarter of compost once or twice yearly. This minimizes the need for resource inputs, the ability of lawn areas to act as infiltration and filter areas, and reduces polluted runoff.

Ideal placement and grass type

Turf should ideally be used where it serves a specific purpose, like a play area. It should be avoided in inaccessible or decorative areas like parkways, median strips, islands, or front yards. Turf should be avoided on all slopes.

Sustainable landscaping for responsible lawn maintenance

Warm season grass is the best choice for most areas in San Diego County. Warm season grass prefers temperatures of 80 degrees or more, and will go dormant in the winter when it is rainy and cool. Typically these grasses grow from sturdy rhizomes that extend deep underground.

Warm season grass also uses less water than cool season grass and is a moderate water use plant. Consider overseeing your grass with clover to make it more interesting and drought-tolerant.

Atmospheric Rivers Benefit State, Regional Water Supply

/in , /by

Atmospheric river events in late January and in February have significantly increased snowpack in the Sierra Nevada and the Rocky Mountains, key sources of water supply for the state and San Diego County.

“We’re thrilled by the amount of precipitation – rain and snow – in San Diego County, the Sierra and the Rockies,” said Dana Friehauf, a resource manager with the San Diego County Water Authority.

The statewide Sierra Nevada snowpack was 151 percent of normal at 104 reporting stations for February 27, according to the California Department of Water Resources. The Rockies have received significant snowfall, which will feed the Colorado River, a source of water supply for the Water Authority. The amount of precipitation in most of the Rocky Mountain region, has ranged from 100 to 150 percent for Water Year 2019 through February 25, according to data from the Natural Resources Conservation Service. The percentage is based on the median between 1981 and 2010.

Record rainfall recorded in San Diego

Locally, a bountiful February has helped make Water Year 2019 one of the wettest on record at Lindbergh Field. Preliminary data from the National Weather Service indicates 10.62 inches of precipitation at the San Diego International Airport, with 3.42 inches coming so far in February 2019.

The Weather Service report issued Feb. 24 also shows that last year at this time, just 1.91 inches of precipitation had been recorded at the airport (for Water Year 2018).

In fact, Water Year 2018 (October 1 – September 30) was the second-driest on record since 1850 at Lindbergh Field, with just 3.3 inches of rain, or 32 percent of the long-term average.

Friehauf reminds San Diegans that even in years such as this, when rainfall is plentiful, that water-use efficiency remains a way of life. For instance, each rainstorm is an opportunity to turn off irrigation systems for days or even weeks at a time. She also suggests residents use rain barrels to collect or “harvest” water that can be used later, when the weather is drier.

Capturing the water from gutters and downspouts also reduces the amount of water flowing into storm drains. Homeowners can get rebates on residential rain barrels. Find details on rain barrel rebates here.

Late-Fall Storms Improve Water Outlook Statewide

/in , /by by Water News Network Staff

San Diego welcomed an unexpectedly large amount of rain since mid-November, surpassing last year’s rainfall total in just the first 10 weeks of the season.

Following the latest storm, two-day precipitation totals on Dec. 7 showed rainfall of 2.6 inches at San Diego’s Lindbergh Field, San Diego’s official weather station. Regional readings ranged from a high of 3.23 inches in the University Heights area of San Diego, to 1.1 inches in Lakeside and less than an inch in the county’s desert areas.

San Diego’s airport reported 3.98 inches of rain between the start of the 2019 water year on Oct. 1 and Dec. 7, according to the National Weather Service.  Just over three inches of rain was recorded at Lindbergh Field between Oct. 1, 2017, and Sept. 30, 2018 – the second lowest total since 1850.

To put the water season in perspective, average rainfall at this time of year is about 1.8 inches.

Sierra Nevada Snowpack off to a Fast Start

In Northern California, late-fall storm systems have dropped a generous amount of snow in the Sierra Nevada, which had been very dry through mid-November. Many mountain areas are reporting twice the average snowpack for mid-December.

More than 60 percent of the state’s water supply comes from Sierra Nevada snowpack as it melts and releases water to lower elevations.  The more snow that falls each winter, the more protection the state builds against drought the following year. 

The news is also positive in the Rocky Mountains, though the Upper Colorado River Basin has been struggling with drought for nearly two decades. Rainfall was at 119 percent of average in mid-November.

San Diego Region has Sufficient Supplies for 2019

For San Diego County, the National Oceanic and Atmospheric Administration’s Climate Prediction Center’s three-month weather outlook for December through February predicts above-normal precipitation across all of California except the very northern tier. The agency also predicts above-normal temperatures for the western states, with a greater than 40 percent probability of above-normal temperatures this winter statewide.

Even if weather conditions were to dry out through September 2019, the Water Authority and its member agencies have enough water supplies to meet regional demands for the foreseeable future. This is possible due to a combination of drought-resilient local and regional water resources, including the Claude “Bud” Lewis Carlsbad Desalination Plant, conserved agricultural water transfers, savings from canal lining projects, and continued water-use efficiency measures.

A weak El Nino is expected to form and continue in the Northern Hemisphere this winter and into the spring. As a result, the U.S. Seasonal Drought Outlook released on Nov. 15 favors drought improvement or removal for California and the southern portion of the Southwest.

Meteorologist Alex Tardy of the National Weather Service San Diego office predicted near-average precipitation in the region in his 2018-2019 outlook, noting that “past precipitation events have been extreme” with extended dry periods between storm patterns that bring heavy rain.
