Spring Valley HOA and Watershed Benefit From Landscape Optimization Service

/in , /by

Conserving water and reducing pollution are two of many benefits from a new program in San Diego County.

Through a partnership between the County of San Diego’s Watershed Protection Program and the San Diego County Water Authority, residences and businesses in unincorporated areas of the county became eligible for newly enhanced water-use efficiency rebates in 2021. The Waterscape Rebate Program saves money for residential, commercial, and agricultural customers who make landscape upgrades to improve the region’s climate resilience and reduce the flow of pollutants into waterways.

The new concierge-style assistance program helped members of a Spring Valley homeowners association benefit from available incentives and rebates. As a result, residents saved money on landscape upgrades while reducing the flow of pollution into waterways and conserving water.

To make applying for rebates easier for large landscapes, the county added a Landscape Optimization Service, a unique technical assistance program for large-scale landscaping projects. The program helps applicants with large landscapes, such as HOAs and commercial properties, navigate the requirements, overcome barriers, and maximize their rebate eligibility.

LOS staff analyzes estimated water and cost savings, which details how quickly the project will pay for itself. The program also offers discounted designs to participants.

The finished project is estimated to reduce water use by almost two million gallons annually. Their total project costs prior to the rebate were approximately $120,000. After the rebates, the HOA paid just $13,000 for the project.

First of its kind assistance program

“Many of our larger customers, such as HOAs, are run by volunteers who don’t have the time or resources to undertake large landscape projects,” said Joni German, Water Resources Specialist at the Water Authority. “Most of their landscapes were put in during the 1970s, and many are ready for a water-efficient upgrade. This partnership with the County enables us to offer HOA customers a first-of-its-kind program with assistance from start to finish.”

Currently, seven San Diego County HOAs are working through the process of removing common area grass with the support of County of San Diego contractor Environmental Incentives.

Their project is estimated to reduce water use by almost two million gallons annually. Their total project costs prior to the rebate were approximately $120,000. After the rebates, the HOA paid just $13,000 for the project.

“The County is proud to partner with HOAs, like the Rancho San Diego Association, to help protect local waterways by transitioning to a more sustainable landscape,” said Scott Norris, Land Use Environmental Planning Manager with the County Water Protection Program. “We look forward to expanding the Landscape Optimization Service in the coming years to assist more properties in upgrading their outdoor space and helping protect water quality.”

Sustainable landscapes produce multiple benefits, which include reducing water use, enhancing habitat, increasing stormwater retention, and decreasing runoff.

The enhanced incentives include rebates starting at $3 per square foot for turf replacement, $60 per smart controller station, $65 per rain barrel, and up to $450 per cistern. In addition to offering technical assistance to upgrade larger landscapes on multifamily and commercial properties, a cost-share is available for agricultural growers to make water-saving upgrades.

Water customers in unincorporated San Diego County can determine their eligibility at SanDiegoCounty.gov/WatershedRebates. The Landscape Optimization Service is actively recruiting new participants.

Protecting our watershed by conserving water

The Waterscape Rebate Program helps to protect local waterways by reducing pollutants that enter storm drains. When irrigation systems overflow from landscaping, runoff may carry pollutants like pesticides, herbicides, and fertilizers into the storm drain system and cause the same adverse effects as runoff from rainfall. Reducing turf helps reduce irrigation use and runoff.

The program includes outreach and education to commercial, industrial, and residential properties in unincorporated areas of the county. San Diego County is also offering programs with rebates for upgrades, including rain gardens, gutters, permeable pavement, and regular septic system pumping.

UN Report: the World’s Farms Stretched to ‘a Breaking Point’

/in , , /by /Yale Climate Connectionsby Dana Nuccitelli

Almost 10% of the 8 billion people on earth are already undernourished with 3 billion lacking healthy diets, and the land and water resources farmers rely on stressed to “a breaking point.” And by 2050 there will be 2 billion more mouths to feed, warns a new report from the United Nations Food and Agriculture Organization (FAO).

For now, farmers have been able to boost agricultural productivity by irrigating more land and applying heavier doses of fertilizer and pesticides. But the report says these practices are not sustainable: They have eroded and degraded soil while polluting and depleting water supplies and shrinking the world’s forests.

Winter Weather Perfect Time for WaterSmart Landscape Makeover Series

/in , /by

December rainfall and cooler temperatures in San Diego County make it the perfect time of year for homeowners to create low-water-use landscaping to fit their needs. The San Diego County Water Authority offers its first 2022 WaterSmart Landscape Makeover Series of free online classes starting Wednesday, February 2. The classes provide homeowners site-specific knowledge, skills, and confidence to transform their thirsty turf yard into a beautiful, climate-appropriate, water-efficient space.

Registration for the four-class series closes on Monday, January 17. Register at WaterSmartSD.org. There is no fee to participate, but course participation is limited.

Custom plans and one-on-one professional guidance

Water Authority Water Resources Specialist Joni German said the course will give participants a customized roadmap to follow.

“We have different templates and themes to design the garden you want,” said German. “Do you need turf for the kids or pets? A meditation space? Or do you want to screen out undesirable views? With our help, you design the landscape that fits your lifestyle.”

Ideal time for new plants

German said with soils now soft and spongy, it’s the ideal time of year to add new plants and creating a new water-wise landscape.

As part of the course, participants will receive a site visit prior to the class, a preliminary onsite CAD drawing of their property to work with during the class, and one-on-one coaching from landscaping professionals.

Turf rebate programs offer rebates of up to $3 per square foot toward project costs for upgrading existing turf. To date, several hundred homeowners have transformed their landscapes into beautiful, climate-appropriate mini-watersheds which yield benefits including stormwater runoff reduction and lessening green waste in addition to saving water.

Positive participant feedback for free program

German said the program has evolved through the years in part due to feedback from previous participants, including information about capturing rainwater and cutting back on irrigation.

“People frequently say to us, ‘I can’t believe this program is free!’ Recent participants tell us the time flies, and they go from feeling overwhelmed to confident about their landscape projects,” said German.

Vallecitos Water District Development Services Coordinator Eileen Koonce participated in the course as a new homeowner to reduce her water usage by removing her thirsty front lawn.

Koonce said she enjoyed working with the instructors.

“They bring the language down to the do-it-yourselfers,” said Koonce. “They walk you through every part of it and if you have questions, they can help you out. You feel empowered because you can understand the process.”

Some In California Have to Limit Their Daily Water Usage to 55 gallons. Here’s What That Means for Everyday Activities

/in , , /by /CBS Newsby Carter Evans

Extreme drought in California is forcing drastic measures on the 200,000 residents in Marin County. They have been told to cut their water usage to just 55 gallons a day.

A 10-minute shower uses about 25 gallons. A load of laundry uses 40 gallons of water. A single sprinkler head can spray out 15 gallons per minute.

The new restrictions mean no refilling swimming pools or fountains. Residents can’t wash their car in their driveways, and outdoor irrigation is prohibited.

Capture Rain-Drought-Rain Barrels-Rebates

Make the Most of Rainfall

/in , /by

On the rare and welcome occasions when San Diego County gets rainfall, the water runoff from hard surfaces around the home such as roofs and patios should be re-directed to your permeable landscaping. By capturing as much rainwater as possible in the soil, it is possible to build an ecosystem that can last through the summer months with minimal additional irrigation.

Approach your landscaping as a living sponge, holding water until it is needed. If more rain falls than can be absorbed, or if the soil is particularly impermeable, rainwater can be directed through landscaped areas to remove pollutants before it flows into storm drains and heads downstream.

Adjust for rainwater capture

Capture rainfall in three steps. First, check your roof to determine where precipitation is directed after it hits the surface.  Does it fall into rain gutters, off the edge, or elsewhere? Second, choose how and where to hold excess rainwater based on this assessment. Finally, consider making upgrades like adding rain barrels or making changes in your landscaping. For instance, landscaping soil may need amendments to hold more water.

Is your soil more like a brick?

If your soil is more like a brick as with clay soils common in San Diego County, it will affect how landscaping is contoured to capture water. Adding soil amendments will help it become more like a sponge that retains water for drier weeks and month. If the soil doesn’t drain well, take special care to avoid drowning new plants.

When choosing landscaping plants, match them to the soil type. If the soil is sandy, look for plants with “dry feet” that prefer free-draining soil, If the soil is harder clay, look for plants that do not mind heavy soil.

Optimal landscape soil can capture rainwater and allow it to soak in completely in 24 to 48 hours.

Do your part to stay WaterSmart

Many homeowners also use rain barrels to capture rainfall before it reaches the ground so it can be released during dry times.

Olivenhain Municipal Water District has partnered with the San Dieguito Water District, Santa Fe Irrigation District, and Carlsbad Municipal Water District to offer discounted rain barrels to area residents this winter.

Rain barrels ordered by January 31, 2022 will be available for pick up at Solana Center for Environmental Innovation located at 137 North El Camino Real in Encinitas.

Fifty-gallon barrels are on sale for $97, with a final cost of $62 after a $35 rebate from water wholesaler Metropolitan Water District of Southern California. Rebates on rain barrels and other water-saving measures are available at www.socalwatersmart.com.

Escondido HOA Saves Water, Costs with WaterSmart Landscape Upgrades

/in , /by

The Emerald Heights homeowner’s association in Escondido recently completed a successful clubhouse upgrade including a landscaping makeover replacing existing turf with a beautiful drought-tolerant design.

The gated community is located within the Vallecitos Water District. It covers 6.2 acres including a private athletic club with tennis and basketball courts, plus a community pool and spa. The landscape of turf and trees surrounding the clubhouse area was not healthy. But it would be challenging to find plant materials well suited to growing in the microclimate under the shade trees.

Emerald Heights HOA representatives met with O’Connell Landscape and Maintenance. Jack Rush, O’Connell’s executive vice president of operations, encouraged the HOA to take advantage of the SoCal WaterSmart turf replacement program.

“It incentivized them by offering rebates to help offset the construction costs [for the clubhouse],” said Rush.

WaterSmart landscape features appealing new look

The HOA had invested in irrigation system upgrades two years ago, including “baseline” smart controllers throughout the community. HOA board president Dan Cannon and committee members worked with HOA property manager Telsa Dubois of Allure Management and O’Connell Landscape Management, project manager Salvador Alvarado, and construction supervisor Basilio Diaz to craft the new plan.

Dry riverbed areas were established in place of existing turf, graded to capture water runoff into these areas. Cobblestones and boulders were added, along with plants featuring different leaf textures and unique flowers. Using plants at different heights enhanced the landscape area and gave it a more eye-appealing look.

Throughout the property, point-to-point drip system irrigation was installed. All remaining spray heads were replaced with drip fixtures.

Ongoing savings help pay for community upgrades  

O’Connell applied for the incentive program on behalf of Emerald Heights HOA through the Metropolitan Water District of Southern California. It was able to remove 2,746 square feet of turf surrounding the clubhouse and tennis court areas. The HOA received $8,238 in rebates for the turf replacement.

“The water savings is still too early to tell, but we estimate 50% to 60% water savings are possible,” said Rush, based on the new plant materials and irrigation retrofitting. Rush says his firm will continue to explore more potential water savings for the community and work closely with members of the HOA.

The Emerald Heights HOA can file a turf replacement application each year to receive more turf rebates. Removing thirsty grass is one of the most water-conscious adjustments it can make to reduce its water usage and associated costs.

The Turf Replacement program is a two-part application process. To qualify for a rebate, customers must apply to reserve rebate funds before starting their project. The landscaping makeover must take place with 180 days, including the request for a rebate. Funding levels are subject to change based on availability at the time of rebate approval.

Fall Back and Adjust Irrigation Systems to Save Water

/in , /by

The end of daylight saving time is a reminder to residents to assess their outdoor watering needs and adjust their irrigation systems to reduce water waste – an especially important step after more than two years of statewide drought. Plants simply don’t need as much water during cooler months, and they typically don’t need irrigation at all after heavy rains.

“This is a great time to make sure irrigation systems are working properly and delivering the right amount of water,” said Jeff Stephenson, a water resources manager for the San Diego County Water Authority. “After two years of drought, using water efficiently and eliminating water-wasting practices is a critical part of preserving more of our precious supply.”

Adjust irrigation systems

Outdoor watering accounts for more than half of a typical household’s water use in California. Making seasonal adjustments to irrigation controllers can help reduce water waste and lead to healthier landscapes. Water-saving practices include turning off irrigation systems when rainstorms are predicted and leaving them off for at least a week after significant rainfall.

Using water efficiently indoors and outdoors is easier than ever thanks to online resources offered by the Water Authority at www.watersmartsd.org. The site is filled with information about conservation incentives, and it includes tools and programs designed to make the most of the region’s most precious natural resource. Saving water is easier than many people realize. A few simple changes can make a big difference – especially outdoors.

The 2021 water year was the driest in California in more than a century, but San Diego County continues to have reliable water supplies due to long-term investments in water sources and infrastructure, coupled with extensive water conservation efforts. Per capita potable water use in the San Diego region has decreased by nearly 50% since 1990 as residents and businesses continue to adopt WaterSmart practices.

Farmers Propose Solutions to Drought Conditions in the Western United States

Boost Your Irrigation IQ

/in , /by

To support and protect your investment in waterwise landscaping, you need to have a strong irrigation IQ and understand the basics. You’ll be able to best maintain and maximize your system’s efficiency, which is vitally important during times of drought in the San Diego region.

Conventional irrigation systems can be inefficient

Well-designed and operated systems can reliably deliver the necessary water to sustain your landscaping without waste or excess. Poorly performing systems can suffer due to bad design, inadequate maintenance, and improper management.

A shutoff valve (ball valve) can be manually operated to cut off the water supply in the event of a leak, a malfunction, or a major repair.

The anti-siphon valve, when activated by an irrigation controller, delivers water through a PVC pipe lateral irrigation line, ultimately reaching the sprinkler head, which applies the water to your landscaping.

Intelligent irrigation systems operate efficiently

Efficient irrigation components are designed to operate at lower pressure levels, as specified by each product manufacturer. Devices are more likely to fail under excess pressure, and damage can occur.

A pressure regulator will eliminate excess pressure.

A submeter can be installed where the irrigation system tees off the mainline to the house. It is a recommended option for large properties to keep track of the actual volume of water being applied to the landscape. Single-family homes typically have a single mixed-use meter which doesn’t distinguish between indoor and outdoor water use. An alternative is to install a flow sensor working in tandem with a smart controller.

Low-volume irrigation devices like rotary nozzles and micro or drip irrigation are designed to deliver water to the landscape at a slower rate. This better approximates the infiltration rate of the soil and reduces runoff.

Smart controllers will automatically adjust irrigation schedules in response to changing weather conditions. They come in two varieties. ET controllers monitor weather conditions. Soil moisture-based controllers directly sample the moisture in the ground. These devices also have features like “cycle and soak functions that can help eliminate runoff. When selecting a controller, look for brands with the EPA WaterSense ® label.

One day in early October, a group of University of California, Merced, students went to the campus Smart Farm, augurs in hand, to explore the soil for the best spots to locate moisture sensors. They were not looking in the root zone to monitor how much water is available but instead for areas lower in the soil to study how irrigation and stormwater can travel far enough beneath the plants to recharge the groundwater below.
