Contour Your Landscape

When planning your landscape, look first at the terrain you’re working with. You can use the contours of your existing land – depressions and slopes – for guidance when planning your landscape grading. If your yard is flat, you’ll need to move soil and features around to create more rain-holding contour areas.

A soil percolation test can be very helpful in preparing your soil. You want to make it as much of a water-retaining sponge as possible before getting to work on rainwater capture plans.

NOTE: If you have existing hillsides, it’s best to get professional advice before grading or other significant changes. Before any digging, call Dig Alert 8-1-1 or visit digalert.org to be sure you won’t hit any underground utility lines.

Move water with gravity

Basins and swales are shallow depressions or channels no more than 24 inches deep on gently sloped or nearly flat landscapes. Basins and swales move water over short distances. With these contours, gravity will move water around to where you want it.

Small, shallow depressions work best in clay soil areas, while sandy soils may accommodate deeper depressions up to two feet. Channels can be planted or lined with rocks and small boulders to resemble natural creek beds.

Use rainwater to your advantage

By planning your landscape so that you don’t have low spots with no plants, you prevent wasting rainwater through runoff. You can also avoid fungus and rot from standing water. Plants in and around the depressions capture and sink small volumes of surface water so that all the rainwater you capture can be used.

Berms are mounds of raised soil, usually planted, that can border basins and swales or be used alone. They help contain and move water around, increasing the holding capacity of basins and swales.

Boulders can add points of interest and slow down water runoff in your landscaping. Boulders also are useful to retain small berms or the edges of swales.

The San Diego County Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.

The San Diego County Water Authority will be among the water industry employers offering career information at the conference.

The Water Authority and its 24 member agencies created a regional workforce development task force to address the ‘Silver Tsunami’ of employees reaching retirement age.

“There are approximately 4,500 water and wastewater positions in the San Diego region and more than 1,400 of those workers are expected to reach retirement age by 2024,” said Gretchen Spaniol, acting special projects manager with the San Diego County Water Authority. “Those retirements provide an opportunity to diversify the water industry workforce, and the Women in Water conference is a great starting place to explore careers in water.”

The series of workshops between 8 a.m. and 3 p.m. wraps up with a tour of the Water Conversation Garden.

Lunch, refreshments, and parking are included in the $35 registration fee. Registration is free for students. For more information about the symposium and Cuyamaca College’s Center for Water Studies, go to centerforwaterstudies.org.

Cash Rebates Increase for Grass Removal in San Diego Region

April 8, 2019

Removing grass can generate rebates of at least $2 per square foot for San Diego residents under new enhanced incentives that started this month.

As of April 1, the Metropolitan Water District is offering $2 per square foot for every square foot of grass removed from yards and replaced with sustainable landscaping.

“San Diego County homeowners and businesses know that sustainable landscapes are key to water reliability in our region,” said Joni German, who manages the Water Authority’s WaterSmart Landscape Makeover Program. “With the help of local landscape architects and designers, our WaterSmart Landscape Makeover Program gives them the knowledge and skills they need to be successful. WaterSmart landscapes are an upgrade, not a compromise.”

Infrastructure

The San Diego County Water Authority sustains a $245 billion regional economy and the quality of life for 3.3 million residents through a multi-decade water supply diversification plan, major infrastructure investments and forward-thinking policies that promote fiscal and environmental responsibility.

California officials toured some of that infrastructure in July as they worked to prepare a water resilience portfolio for the state. Our reporting on the July 18 water portfolio tour was the third most read story of 2019 on the Water News Network.

The Nifty 50: Best Plants for WaterSmart Landscapes

Are you looking for new plants or trees to upgrade your WaterSmart landscape? Check out the Nifty 50. These 50 plants and trees thrive in San Diego County’s arid climate, and the rainy fall and winter are a perfect time to introduce them into your landscape. They are attractive, non-invasive, easy to maintain and drought-tolerant.

Timing is important

During the first 12 months in your garden, called the establishment period, new plants need extra water. Before bringing them home, make sure to check your irrigation system and water pressure.

A good resource for estimating the right amount of water for your landscape is the City of San Diego’s Landscape Watering Calculator.

The calculator is based on historical weather data for your zip code and can tell you more about water requirements for the plants, soil and sprinkler type in each of your irrigation zones. It will work for any location in San Diego County.

Map out your landscape

Once you have an efficient irrigation system set up, choose your new plants. Trees are a great way to line your property and block out the sun, noise and wind. They can help you collect rainwater and provide a beautiful backdrop for other plants.

Certain types of shrubs pair well aesthetically and attract pollinators like butterflies and hummingbirds. California Lilac, Manzanita, and Toyon are good examples of shrubs that will bring pollinators and other wildlife to your garden.

To add some texture and dimension to your landscape, look for colorful groundcovers like Trailing Lantana or Stonecrop.

Authentic means sustainable

Plants native to the region have adapted over thousands of years, and native animal species depend on them as well. There are thousands of ground covers, grasses, succulents, perennials, shrubs, vines and trees to choose from in addition to the Nifty 50. For more information, go to WaterSmartSD.org.

WaterSmart Contractor Incentive Program

New Rebates For WaterSmart Irrigation Devices in San Diego County

A new rebate program for irrigation devices is available to qualified landscape contractors in San Diego County.

The WaterSmart Contractor Incentive Program, or WSCIP, is designed to help commercial, public and agricultural property owners improve water-use efficiency in large landscapes, through rebates for irrigation hardware upgrades. School districts, universities, and other organizations are also eligible.

WaterSmart offers water efficiency programs, services and incentives for residents, businesses and farmers in San Diego County.

Rebates for innovative irrigation devices

Qualifying project sites must include at least one acre of irrigated landscape. The rebates are offered on a first-come, first-served basis.

“The incentive program was designed to be business-friendly and is part of the Water Authority’s focus on long-term water-use efficiency,” said Efren Lopez, a water resources specialist with the Water Authority, who manages the new program and the Qualified Water Efficient Landscaper Program.

The WaterSmart Contractor Incentive Program is a large landscape and technology-focused program, which targets qualified landscape contractors and self-managed sites. The Water Authority’s mission is to improve water-use efficiency in large landscapes by retrofitting irrigation devices.

Catching and Storing Rainwater for Your Landscape

During the rainy fall and winter seasons in Southern California, catching and storing rainwater is beneficial for cutting down on irrigation costs. It can also be stored for later use through the rest of the year.

Know the path rainwater will take

If there are rain gutters on your house, water will flow into downspouts, where it can move with great force and speed. This is especially true in a large storm. Instead of allowing downspouts to discharge directly on hard surfaces like a driveway, path, or patio, plan ways to redirect downspout water into vegetated landscape areas. This will be a more efficient use of the natural irrigation.

Replacing downspouts with “rain chains” to slow down the water is one option. This way, water can be more easily absorbed when it reaches your landscape. Add a rain barrel or cistern at the bottom of downspouts or rain chains and let it overflow into your garden.

If your house does not have rain gutters, water shears off roof surfaces and can cause erosion damage. Cover areas under the eaves in permeable ground covers such as pea gravel, mulch, or rocks. Ground covers can reduce the compacting force of water falling on bare soil. Spread fresh leaf and wood chip mulch throughout the garden to slow down water. Healthy soil can withstand even the strongest rain. Once the rainwater is absorbed into the soil, your plants’ roots will grow deeper. This will help them thrive throughout the year.

Ways to store rainfall

Rainwater can also be harvested and stored. Rain barrels and cisterns directly connected to downspouts are great storage containers. Check out your local water district or water agency to see if there are any rebates or incentives available.

Stored water can be released gradually into the landscaping between winter rainstorms. This will help build up the soil sponge and ensure that native plants get adequate water when they need it most. If you need water in the summer and capture enough of it during the winter, you may be able to use your stored water for irrigation.

Both rain barrels and above–ground cisterns can be relatively inexpensive to purchase and easy to install. Use screens to keep mosquitos out. With minimum maintenance and common sense, you can keep the water safe and clean. If you plan to store rainwater, make sure the “first flush” is diverted directly into the landscaping before capturing the rainfall that follows. This is important because the “first flush” will collect debris and contaminants that have built up on surfaces throughout the dry months.

Use your landscape to capture rain

You can design your landscape to effectively collect water. Properly placed trees are excellent landscaping features to help capture rainfall, allowing it to be released slowly over time into the soil. Taller, stronger plants placed strategically can also allow you to control the flow of water.

With a little planning, you can capture and store rainwater easily and effectively during the rainy season and use it throughout the year.

Valley Center MWD Cool Valley Reservoir

Valley Center Reservoir Project ‘Exceptional’

The Valley Center Municipal Water District has been advised by the California State Water Resources Control Board that its Cool Valley Reservoir Cover Replacement Project was recognized by the Environmental Protection Agency’s new AQUARIUS Program as an “Exceptional Project,” among only 10 identified as such nationwide.

Each year, EPA’s Aquarius Program recognizes one Drinking Water State Revolving Fund project from each of its 10 regions nationwide for “exceptional focus on sustainability, protection of public health” while demonstrating a high level of innovation.

The $4.2 million Cool Valley Reservoir Cover Project was nominated by the SWRCB, EPA’s state-level partner in the DWSRF Program in California.

Cool Valley Reservoir Project ‘Innovative’

Constructed in 1975 and with the original floating flexible reinforced “Hypalon” material installed in 1992, Cool Valley is Valley Center’s largest drinking water reservoir with a capacity of 57 million gallons, providing about 40% of the District’s total covered drinking water storage capacity. By 2015, the floating cover had reached its full life expectancy and started to experience failures, possibly placing the quality of the water in the reservoir at risk. 

At that point the decision was made to take the reservoir out of service and seek DWSRF financing to cover the estimated $4.2 million project cost, rather than make additional repairs to the existing liner. 

With interim adjustments to system operations and cooperation from Valley Center’s wholesale supplier, the San Diego County Water Authority, the system operated reliably with Cool Valley off-line.

‘Exceptional Project’ reduces bacteria and energy use

District engineering staff and consultants were successful in securing the 20-year loan at 1.6% interest. With the loan secured, the project was approved by the Valley Center Board in the FY 2015/2016 Budget.  The project took 12 months to complete and was back on line by mid-2017. The effort was overseen by Wally Grabbe, District Engineer and managed by Dennis Williams (retired), Deputy District Engineer. 

Projects nominated by the states must meet three major criteria, including providing Safe Drinking Water Compliance, Public Health Benefit and having Financial Integrity.  Additionally, each project must demonstrate leadership in dealing with emerging contaminants, aging infrastructure or innovative financing, affordability, water loss control, efficient water and/or energy use, creative approach to project planning and implementation, and/or creating water system partnerships.

In making the award, the SWRCB and EPA noted that the Valley Center Cool Valley Project will not only protect water quality from atmospheric vectors, but the new cover-liner will “prevent leakage from the reservoir, reduce bacteria by creating a barrier between the drinking water and the concrete liner… and reduce chemical and energy use.

During the same period of time, the Valley District designed and installed a 95kW Photovoltaic Solar Array and upgraded the Cool Valley Pump Station, all located on the Cool Valley Reservoir site.

RE:BORDER 2019 Jim Madaffer - The Water We Share

Cross-Border Water Issues Need Cross-Border Solutions

Regional collaboration and partnerships are needed to solve cross-border water issues, according to San Diego County Water Authority Board Chair Jim Madaffer.

“The Water Authority is exploring innovative solutions to increase water supply reliability for the San Diego region, but also Baja California and the Southwest,” said Madaffer during today’s opening ceremony of RE:BORDER 2019 at San Diego State University. “Those solutions include the possibility of a transborder water connection that can help both Mexico and the United States.”

Madaffer’s special presentation, “Stewarding a Shared Resource for the Bi-National Region,” was part of the two-day RE:BORDER 2019 conference. It continues Tuesday at the Universidad Autónoma De Baja California in Tijuana.

‘The Water We Share’

The theme for the inaugural binational conference is “The Water We Share.” The goal is to forge regional solutions for transborder water issues by breaking down academic, political, and administrative boundaries.

In his opening remarks, San Diego Mayor Kevin Faulconer, was optimistic about solving Tijuana sewage issues, such as polluted runoff flowing into the Tijuana River causing beach closures in Imperial Beach and Coronado.

Momentum increasing for cross-border solutions

“I’ve never seen more momentum than I have in the past six months to solve this cross-border sewage issue,” said Faulconer. “It is a true international issue that we can solve.”

‘Borders are arbitrary, but we are connected’

California State Water Resources Control Board Chair E. Joaquin Esquivel delivered the keynote address.

“The borders are arbitrary, but we are completely connected,” Esquivel told a crowd of about 200 people in Montezuma Hall. “Infrastructure investments are needed on both sides of the border, and we know with climate change, the entire watershed will be an entirely different place in the future.”

Day 2 sessions in Tijuana will examine how the transborder region will be affected by climate change – including greater risks of floods, landslides and wildfires – how reduced water for agriculture could impact the region, and on-going concerns about uneven access to water resources.

RE:BORDER is a new initiative from San Diego State University President Adela de la Torre that each year will examine a significant issue.  The RE:Border 2020 conference is scheduled for November 12 and 13.

Prepare Your Landscape for the First Rain

After a dry spell, the first rainfall is the most important water to capture for your landscape. This is called the “first flush.”

In arid regions like San Diego County, this happens every year because there is a long stretch of dry weather in between rainy seasons.

Why is the first rainfall so important?

It washes away pollutants that have collected since the last rain. This water needs to be filtered as much as possible by landscaping before it goes anywhere else. Usually the next stop for this water is storm drains that empty into oceans. So your landscape can be a very important tool in preventing the buildup of pollutants in local water supplies.

In addition, the first rain in the fall is very important for your plants. New or established plants will want to grow deep roots in the fall and winter, and the additional water is essential. Capturing the rain with your landscape reduces the need for increasing irrigation.

How much water comes off your roof?

Measure the size of your roof to determine how much water will come off it. The shape of your roof doesn’t matter in this instance. The same amount of water falls on the roof whether it is sloped or flat. You can measure a sloped roof either using an aerial view or from the ground without worrying about the slope itself. Just measure the outside edges the same way you would if it was flat and calculate the square footage.

Flat roofs covering a building in one contiguous shape are easier to measure. Some roofs are more complicated. You can divide this type of roof into individual squares or triangles. Then, measure each one at a time and add the figures together for your total roof area.

Calculate your potential water capture

Once you know the total roof area, you can determine the amount of rainfall it generates in gallons, then use the following formula to convert square feet to gallons.

Formula: Rainfall in Inches x Total Square Feet x 0.62 = Gallons of Rainwater from the Roof

Here’s an example using a 1,000 square foot roof: 1 inch of rain x 1000 x 0.62 = 620 gallons.

Even in a dry climate, this rainfall adds up to a lot of water runoff. It’s easy to see how important it is to save as much of this water as possible in a landscape designed to be a sponge instead of a brick. Take the watershed approach to designing your landscape, and you can use the first flush of rain to your advantage.

The San Diego County Water Authority and its partners also offer other resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.
