Quick Solution Keeps Pipeline Repairs On Track

/in , /by /Water News Network

When Water Authority crews began dewatering part of the region’s pipeline system for a 10-day shutdown in mid-November, they discovered a leaking valve that threatened to disrupt the time-sensitive operation. At issue was a six-foot diameter valve in the Second Aqueduct that was designed to isolate a section of pipeline so workers could safely make repairs inside a dry section of the massive pipe. Instead, the valve was seeping water, which made it impossible to start the welding work slated for the relining project in Bonsall and Fallbrook.

Defeat Of Water Bond Imperils Desert Community Of Borrego Springs

/in , /by /The San Diego Union-Tribuneby J. Harry Jones

It’s back to square one for the desert community of Borrego Springs, which is facing the daunting task of reducing its consumption of water by at least 75 percent in the coming decades. Mostly lost in the hubbub surrounding the Nov. 6 election was the defeat of Proposition 3, an $8.8 billion state water bond. Had it passed, Borrego Springs would have received $35 million to fallow most of the 3,800 acres of citrus and other farms in the northern part of the community.

Bigger Wildfires. Worsening Droughts. More Disease. How Climate Change Is Battering California

/in , /by /Los Angeles Times

Analyses estimated that the area burned by wildfire across the western United States from 1984 to 2015 was twice what would have burned had climate change not occurred. Wildfires around Los Angeles from 1990 to 2009 caused $3.1 billion in damages (unadjusted for inflation). Tree death in mid-elevation conifer forests doubled from 1955 to 2007 due, in part, to climate change. Allowing naturally ignited fires to burn in wilderness areas and preemptively setting low-severity prescribed burns in areas of unnatural fuel accumulations can reduce the risk of high-severity fires under climate change. Reducing greenhouse gas emissions globally can also reduce ecological vulnerabilities.

HOA Homefront: Saving Our Lawns Or Saving Our Artificial Turf?

/in , /by /The San Diego Union-Tribuneby Kelly G. Richardson

Our board has indicated that they plan to remove all turf from the front yards of our community and replace it with various types of non-turf plants. The vast majority of homeowners oppose such a plan. Can a board make a decision of this nature and magnitude without homeowner approval? Their decision would make a highly significant change to the appearance of our community.

Delta Tunnels Opponents Score A Victory

/in , /by /The Press (Brentwood)by Tony Kukulich

In the bitter battle over the future of the California WaterFix Project, opponents recently scored a victory in their effort to stop the construction of Delta Tunnels. The development occurred when the Delta Stewardship Council (DSC) staff issued a preliminary finding stating that WaterFix, as it exists today, is inconsistent with the Delta Plan. Without a certificate of consistency, the Department of Water Resources (DWR) cannot move WaterFix forward.

OPINION: L.A. Wasn’t Built In The Desert, But The Desert May Be Coming To Us

/in , /by /Los Angeles Times

It’s hard out there for an environmentally responsible but thirsty Angeleno — someone who wants to grow a couple organic tomatoes in the backyard, take more than an occasional shower and still have enough money to repair the rain barrel after paying the various water bills, fees and taxes. Measure W, which voters passed on Nov. 6, will help. But it won’t put an end to our water problems.

Mirroring Native Plant Communities in Sustainable Landscaping

/in , /by

In nature, plants arrange themselves into communities of “friends” based on common microclimates, water and nutrient needs, and how they interact with the physical environment. Native plant communities also are based on interactions with each other and other species such as insects, birds, and other animals.

Most plant communities occur repeatedly in natural landscapes under similar conditions.

Local native plant communities have evolved together over a long period of time, and grow well together. They will even “reject” the outsiders and work together to compete for nutrients, sunlight, and other resources

This is one of many good reasons to learn about the San Diego region’s native plant communities and to select plants that like to live together in communities for sustainable landscaping.

Three examples of San Diego regional plant communities

California Coastal Prairie Community

California’s coastal prairies are the most diverse of any grassland in North America. Perennial flowers outnumber grass species here. Plants include: California Poppy (Eschscholzia californica), Blue-Eyed Grass (Sisyrinchium), Fern Leaf Yarrow (Achillea ‘Moonshine’), Seaside Daisy (Erigeron glaucus), and Cliff Buckwheat (Eriogonum parvifolium)

California Coastal Sage Scrub Community

California coastal sage scrub features fire-adapted, drought deciduous plants, which are rapidly disappearing to urbanization in southern California. Fortunately, some areas, including the San Diego Safari Park Biodiversity Reserve, have been conserved. Plants include: grey musk sage (Salvia Pozo Blue), sticky monkeyflower (Diplacus aurantiaus), San Diego sage (salvia munzia), fuschia gooseberry (Ribes speciosum), and woolly bluecurls (Trichostema lanatum)

California Chaparral Community

Chaparral exists in many coastal ranges, and on the western and eastern slopes of the southern California mountains. It is ‘hard’ brush that doesn’t rely as much on summer fog as the Coastal Sage Scrub does, and it is adapted to heat and drought. Plants include desert mallow (Sphaeralcea ambigua), bent grass (Agorstis pailens), San Diego mountain mahogany (Cercocarpus minutiflorus), bush poppy (Dendromeconi riguda), and clumping wild rye (Leymus condensatus),

OPINION: End Of An Era At Valley Center Municipal Water District

/in , /by /Valley Roadrunnerby Gary Arant

Something profound happened at 3:22 p.m. on Monday afternoon, November 19, 2018, at the Valley Center Municipal Water District. After serving as a Director for Election Division 3, Board President, and San Diego County Water Authority Representative, Gary A. Broomell walked out of the board room for the last time as a water board director. As the general manager of the district for close to 30 years, i have seen a few board members come and go.  What was profound about Mr. Broomell’s final exit was that it came after 48 years of continuous public service to the citizens, ratepayers and landowners of the Valley Center Municipal Water District.

California’s First Real Soaking of the Season Brings Wildfire and Smoke Relief But Also a Threat of Debris Flows

/in , /by /The Weather Channelby Linda Lam and Jonathan Erdman

A major weather pattern change has arrived on the West Coast, bringing relief for California’s wildfires and choking smoke, but it may also unleash enough rain to trigger dangerous debris flows in recently burned areas of the state. Northern California’s Camp Fire, the deadliest and most destructive wildfire on record in state history, is still not fully contained. Smoke from the fires has hung over millions, fouling air quality since last week in the Central Valley and Bay Area. Air quality has begun to improve but remains unhealthy for sensitive groups on Wednesday in the Central Valley of California.

San Diego Region Can Expect Light Rain on Thanksgiving Morning

/in , /by /Times of San Diegoby Chris Jennewein

A low-pressure system sweeping into Southern California will produce light rain throughout San Diego County on Wednesday evening and continue into Thanksgiving Day. The National Weather Service office in San Diego said the majority of the rainfall is expected late Wednesday evening and early Thursday morning. Escondido and Oceanside are expected to receive around a quarter-inch of rainfall, while one-tenth of an inch is expected near the coast and in the western valleys. The mountains are forecast to get between a quarter-inch and one-third inch, and the deserts less than one-tenth of an inch.
