Nestled along the Central Coast, Cambria is a picturesque town famous for its vintage clothing and antique shops, its one-of-a-kind olallieberry pies, its scarecrow festival in the fall and its Disneyesque Christmas market and light display in December. Located right off of Highway 1 and 73 miles south of Big Sur, it’s a popular stop for those driving on the Pacific Coast Highway.
Even in late May, when T-shirts take over and thermostats hit a balmy 70 degrees, patches of snow cling to the top of Mount Spokane.
Snow persists on many Pacific Northwest mountains well into summer. It acts as a natural reservoir, melting as the weather warms and watering the thirsty low country when rains are few and far between.
In some of the world’s driest places, atmospheric moisture is a major source of water for native ecosystems. Some algae, plants and insects in the Israeli and Namibian deserts get much of their water from fog, dew and humidity. The spines of some cacti species have evolved to collect fog droplets. California’s redwood forests derive a significant amount of their moisture from fog.
Tucked into the Santa Monica Mountains, the average home here goes for around $1.8 million, the gardens are bursting with pansies fit for rainy England, and hefty fines have done little to restrain many homeowners from squandering water in a time of drought.
This week came a measure of last resort. The local water agency began choking the taps of the worst offenders, limiting the water flow of those who flouted water conservation rules, paid the fines, and kept on flouting. Their showers will henceforth slow to a trickle. Sprinklers will be rendered unusable. Good luck refilling the pool. Or the koi pond.
If there is any source of water that ought to be optimized, it is the wastewater produced by California’s urban centers. Perennially issuing from sewage treatment plants throughout the state, every year this torrent of mostly treated effluent is equivalent in volume to the San Joaquin River in a wet year.
The California Department of Water Resources estimates statewide urban water consumption at approximately seven million acre feet per year. Just over three million of that total is estimated to be so-called “interior” water use, which means this water is flushed or drained through sewer systems into a wastewater treatment plant.
Every individual landscape sits in one of San Diego County’s 16 watersheds. The watershed approach to landscaping considers every garden its own mini-watershed, holding onto or cleaning the water falling on it and nurturing a diverse habitat of plants and insects.
Each mini-watershed can be controlled by the people who steward it. Individual landscaping choices add up to collective community action. As a result, these collective actions have the ability to restore the county’s greater watersheds.
Every landscape has unique opportunities and constraints. A thorough evaluation helps to identify them and inform the planting and design choices. Spend time in your yard, observe and take notes about it. Identifying multiple site elements will help you make decisions as you start the design process.
Notes should include the home’s architectural style and materials, good and bad views, slopes, and plants and trees you want to protect. Locate utilities and major irrigation items such as your water meter, controller, and valves.
There’s so much more to soil than most people new to landscaping projects realize. Soil is the growing medium for plants. Its nutrients support healthy plant growth. Knowing and working with existing soil conditions and composition is a powerful strategy to maximize water efficiency.
Healthy soil controls the behavior of water: how it moves through the soil and how long it holds on to it. Healthy soil is essential to irrigation efficiency and plant health. It’s possible to build better soil even if existing soil conditions aren’t optimal.
First, you must figure out what kind of soil you’re working with. There are three basic soil types: clay, silt, and sand. Clay soil is made of the smallest particles. Sandy soil is composed of the largest particles. Loam, an equal blend of sand, silt, and clay, is considered the ideal. In general, sandy soil drains faster than clay soils.
Soil structure is also vitally important. Hard, compacted sandy soil will not absorb water. Healthy clay soil can behave more like a sponge, holding and releasing water when necessary.
San Diego County residents must often deal with clay soils and work to improve them to provide the best growing conditions and watershed.

The Vista Irrigation District awarded college scholarships to seven high school seniors selected as winners of the district’s annual scholarship contest. Three fourth-grade students from the local community were also selected as winners of the district‑sponsored Student Poster Art Contest.
The U.S. national drought early-warning information system, called NIDIS, gave a rundown Thursday on when much of the Southwest will experience conditions that heighten the potential for wildfire.
Drought is one of the main drivers because less water means drier soils, drier plants and drier air, all conditions that fuel wildfire.
A major electric vehicle manufacturer has inked a 10-year deal with a company operating at the south end of the Salton Sea for battery-grade lithium hydroxide, a huge boost for nascent production in an area that has long struggled with unemployment and pollution.
Controlled Thermal Resources’ Hells Kitchen project has signed a binding agreement with Stellantis N.V. to supply the product for use in Stellantis’ North American electrified vehicle production.
Water restrictions began Wednesday for 6 million residents in Southern California, as the state enters its third year of severe drought and what water officials say is the state’s driest year on record.
Residents and businesses must limit their outdoor watering to one or two days per week or to a set volume of water, the Metropolitan Water District of Southern California announced.
