While repairing leaks of Fallbrook Public Utility District facilities, FPUD staff temporarily patched 40 sites with cold mix asphalt. On March 22, FPUD’s board awarded Onyx Paving a contract for a one-time paving project to replace the cold mix patches with permanent hot mix paving. The 5-0 vote awarded Onyx Paving the contract for $77,120.
You’ve decided to eliminate the thirsty turf areas in your current landscaping when planning your new sustainable landscape. It’s tempting to install hardscape. It needs no water at all. It might seem like a smart idea, but it creates a new problem: stormwater runoff. It can also increase temperatures and add in its own small way to global warming.
Finding alternatives to cover the area with plants instead of hardscaping will help prevent too much stormwater runoff and capture rainfall.
Consider replacing your lawn with groundcovers. There are many good choices of groundcover plants that make good lawn substitutes. Many species grow well in San Diego County’s six climate zones and the Mediterranean climate natives fall into the very low or low Plant Factor categories. They won’t use as much water than the same amount of grass.

Three potable water reuse or recycling projects under development in the San Diego region were highlighted this week during the San Diego Green Building Council’s inaugural “Sustainable Building Week San Diego.”
The Sustainable Building Week programs focused on sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building.
The panel discussion, “Potable Reuse: New Local Sources of High-Quality Drinking Water for San Diego County,” updated the development status and future benefits of three projects: Pure Water Oceanside, Pure Water San Diego, and the East County Advanced Water Purification program. Attendees learned how the technology works and how it reduces reliance on imported water, while increasing local supply.

“Potable reuse has multiple benefits, including sustainability and drought resilience,” said Lesley Dobalian, principal water resources specialist for the San Diego County Water Authority and the panel moderator.
“Water supplies are subject to lots of vulnerabilities, including rising costs, energy consumption, natural disasters, and eco-system and environmental issues,” said Cari Dale, City of Oceanside water utilities director. “Pure Water Oceanside replicates and accelerates Nature’s natural recycling process.”
The City of Oceanside is working toward creating 50% of its water supply locally, including Pure Water Oceanside, by 2030.

Kyle Swanson, director of advanced water purification with the Padre Dam Municipal Water District, said the East County Advanced Water Purification project would recycle 15 million gallons of annual wastewater discharge into a resource. Currently, wastewater from East County travels 20 miles to be discharged into the San Diego metropolitan wastewater treatment system and eventually into the Pacific Ocean.
“Redistribution of this water would meet 30% of the demand for potable water in East County,” said Swanson. “It is sustainable, uninterruptable, and competitive in costs.”

Pure Water San Diego is the $5 billion project designed to generate 83 million gallons of water per day by 2035, nearly one-half of San Diego’s water demand based on the new 2021 urban water management plan.
“That’s pretty exciting, half our water supply is from this project,” said John Stufflebean, assistant director, City of San Diego Water Utilities Department.
Phase 1 will produce 30 million gallons of water per day by 2025; Phase 2 will deliver the remaining supply.
Potable reuse will provide a new source of safe, high quality drinking water in San Diego County. This local supply is sustainable, drought resilient, and benefits the environment. It will also help prepare the region for future droughts and a changing climate.
Drought is back in California. Federal and state agencies are warning of potential water shortages in the months ahead. Because of investments made by the San Diego County Water Authority, its member agencies and the region’s water ratepayers, San Diego County is safe from the threat of multi-year droughts.
Earlier this month, camera crews once again gathered in the Sierra Nevada to watch a man plunge a pole through the snow. The pole was removed and, following a tense few moments, Californians learned we experienced another dry winter, and we are plunging further into drought. These snowpack surveys are quaint rituals, but they’re also a jarring reminder of how little technological innovation has occurred in California’s water sector. The case for action is clear.
With California in the throes of a second year of drought conditions, the mega-water agency of Southern California served notice Tuesday that it’s prepared to spend up to $44 million to buy water from Northern California to shore up its supplies.
The board of the Metropolitan Water District of Southern California, which serves 19 million urban residents, authorized its staff to begin negotiating deals with water agencies north of the Sacramento-San Joaquin Delta, where supplies are generally more plentiful.
It’s that time of year, when we find out it’s that kind of year. We appear at the doorstep of a “critically dry year,” and most reservoir levels are significantly below average. Those conditions bring painfully to mind the awful drought years of 2014 and 2015, and threaten water supplies for California farms and cities, and for the protected fish species that must also get by in these lean years. For direct diverters, the State Water Resources Control Board recently sent letters to 40,000 water right holders of record, asking them to start planning for potential water supply shortages later this year, and identifying actions water users can take to increase drought resilience.
While the federal government sees the prospect of raising the height of Shasta Dam as a way to increase water storage for a thirsty California, the Winnemem Wintu of Shasta County see it as a threat to their culture.
It was a theme picked up this week by American Rivers, a conservation group that named the McCloud River one of America’s 10 most endangered rivers because of the proposal to raise the height of Shasta Dam.
California’s agricultural community made clear in a series of public meetings last month that growers, dairies and ranchers stand ready to expand forward-thinking environmental practices — but that such activities don’t necessarily make financial sense without some form of government support.
For more than 100 years after California’s Gold Rush, developers and city leaders filled in San Francisco Bay, shrinking it by one third to build farms, freeways, airports and subdivisions.
All that changed in the 1970s with modern environmental laws. But now as sea level rise threatens to cause billions of dollars of flooding in the coming decades, the bay is going to need to be filled again — but this time in a different way, according to a new scientific report out Tuesday.
