Make Space for New Plants

When choosing new plants for your landscape this fall, be sure to account for the space each plant will need as it matures. This will help avoid overcrowding in your landscape.

Proper plant placement, while predicting the mature plant’s size, also should limit the need for future pruning. This can help reduce the amount of maintenance required in the long run.

The spacing chart below helps to judge how many plants are needed per square foot, based on the mature size of the plants.

Plan for space needed at maturity

On your landscaping plan, use circles to note the size of every plant at maturity using a scale in which one inch equals four feet. Use colored pencils to note different water needs of each plant. That will make it easier to group plants into their proper irrigation zones (hydrozones).

Wide canopy trees that grow to 20 or 30 feet in diameter will significantly change the landscaping over time. Consider whether a tree will cover a large section of landscaping with shade that is currently getting full sun. Be sure to avoid placing plants that will need full sun underneath these trees.

Small but mighty

Select the smallest, healthiest plants possible, especially when choosing native plants. Once they are planted in properly prepared soil and watered wisely, small plants establish themselves more vigorously than plants raised in larger containers. Do not plant more than the space will allow for when the plants are fully grown.

Root depth matters

Take note of the root depth of plants when you place them. Note root depths on your landscape plan. Trees will be irrigated less frequently, but for a longer period of time. Groundcovers with shallower roots require more frequent, shorter periods of irrigation. Keep these types of plants in separate hydrozones.

Trump Plan Could Bring Growers More Water. But Will It Harm California’s Rare Salmon?

The Trump administration this week declared that pumping more water from the Sacramento-San Joaquin Delta to supply farms will not jeopardize the endangered salmon and smelt that live in the estuary. This clears the way for the federal government to deliver more water, possibly as soon as next year.

The decision is a big and controversial step toward providing more water for people and less for fish. But the battle, yet another in a decades-long struggle for California’s water, has only just begun.

Understanding Streamflow is Vital to Water Management in California, but Gaps in Data Exist

California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring. That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons.

WOTUS Lawsuits Start Long, Muddy Legal Battle

Get ready for a surge of lawsuits over the Trump administration’s decision to walk back Obama-era protections for wetlands and streams. Opponents to the administration’s take on which water bodies are considered “waters of the United States” under the Clean Water Act already launched at least two challenges this week, kicking off the next round of courtroom action. The cases add a new dimension to what could soon be a complicated legal quagmire over the Obama administration’s WOTUS rule and the Trump administration’s efforts to both erase and replace the regulation.

How Feds New Water Plan Could Affect Customers in SoCal

The Trump administration on Tuesday unveiled new rules to govern California’s scarce water, committing to send more to farmers in the Central Valley despite warnings from environmental groups that it would imperil endangered species in the fragile San Joaquin Delta. The rules govern management of the federal Central Valley Project and the State Water Project, two complex labyrinths of dams and canals that corral rain and snowmelt to provide water to more than 25 million Californians and millions of acres of farmland. An initial review by the National Marine Fisheries Services in July concluded the plan would threaten the existence of some endangered species, including winter-run chinook salmon, according to the Los Angeles Times.

OPINION: A Win for Endangered Fish and California Farmers Who Need Water

To the editor: I would like to highlight the most important information in your recent article about new rules that will govern California water deliveries and environmental protections: “Under the new rules, [U.S Fish and Wildlife Service official Paul Souza] said [Sacramento-San Joaquin Delta] pumping restrictions would be based on real-time monitoring of where smelt and migrating salmon are swimming in the delta, rather than the seasonal prescriptions contained in the current regulations.” The new rules are based on the latest science and real-time monitoring rather than a particular calendar date to determine the needs of fish. This is good news for all Californians.

Fitch Boosts Desalination Plant Bond Rating

Bonds from the Carlsbad Desalination Plant and pipeline were upgraded to BBB and given a stable outlook in a new report from Fitch Ratings, affirming the project’s sound management and its ability to provide a stable, reliable source of drinking water to the San Diego region. As the largest, most technologically advanced and energy-efficient plant of its kind in the nation, the Claude “Bud” Lewis Carlsbad Desalination Plant’s stability stems from an effective collaboration between Poseidon Water and the San Diego County Water Authority.

Santa Barbara Water Agencies Say No to State Water Tunnel Project

Local water agencies aren’t buying into the new version of the Sacramento-San Joaquin Delta “twin tunnels” project, and Santa Barbara County members of the State Water Project voted Thursday to opt out entirely.

The California Department of Water Resources’ Cal Waterfix project, also known as the twin tunnels, aimed to increase State Water Project reliability by building two 40-foot-diameter tunnels to move water under the Delta instead of through it.

Editorial: California Governor Newsom Must Defend Delta

Gov. Gavin Newsom hasn’t flinched in fighting President Trump when it comes to loosening pollution rules in a smoggy state or punishing immigrants seeking protection. But he’s oddly noncommittal when it comes to a federal water grab that rewards thirsty farmers and Southern California cities.

Last week, federal rule makers followed White House dictates and issued looser restrictions on diversions from the state’s prime water faucet, the Sacramento-San Joaquin River Delta.

Fitch Boosts Desalination Plant Bond Rating

Bonds from the Carlsbad Desalination Plant and pipeline were upgraded to BBB and given a stable outlook in a new report from Fitch Ratings, affirming the project’s sound management and its ability to provide a stable, reliable source of drinking water to the San Diego region.

As the largest, most technologically advanced and energy-efficient plant of its kind in the nation, the Claude “Bud” Lewis Carlsbad Desalination Plant’s stability stems from an effective collaboration between Poseidon Water and the San Diego County Water Authority.

That partnership will continue under a transfer of ownership from Orion Water Partners to Aberdeen Standard Investments approved Thursday by the Water Authority’s Board of Directors. The transfer – made public in June – will not alter day-to-day operations at the Carlsbad facility or create a fiscal impact to the Water Authority.

Poseidon Water continues to manage desalination facility

The plant will remain governed by terms of the 2012 Water Purchase Agreement between Poseidon Water and the Water Authority. That 30-year agreement requires Poseidon to obtain the Water Authority’s written consent of the transaction and to reimburse the Water Authority for its costs related to consideration of the consent request. Under the WPA, the Water Authority agreed to purchase between 48,000 acre-feet and 56,000 acre-feet of water from the desalination plant each year at a price established by the contract.  At the end of the 30-year term the Water Authority can assume facility ownership for $1.

“We are honored that maintaining Poseidon Water as the facility manager was integral to the Water Authority’s approval of the ownership transfer and by the Water Authority’s acknowledgement of our exemplary stewardship of this valuable resource,” said Carlos Riva, CEO of Poseidon Water. “We look forward to working alongside our new partners to continue providing the San Diego region with a climate-resilient drinking water supply and ensuring the plant continues its strong operations.”

Desalination plant is ‘hedge against drought’

Water Authority Board Chair Jim Madaffer said the desalination plant is a valuable asset that provides high-quality water, a hedge against drought and insurance against earthquakes that could disrupt imported water deliveries. “With more than 50 billion gallons of water produced and counting, the Carlsbad plant is a critical part of our region’s infrastructure – and we don’t expect the sale to change that in any way,” he said. “In fact, we anticipate many more years of productive partnering with Poseidon.”

The Carlsbad Desalination Plant has met approximately 10% of the San Diego region’s water needs. The planned construction of new, technologically advanced and environmentally sensitive intake and discharge facilities will further enhance operations.

Higher ratings expected to save ratepayers money

Plant partners also praised the improved ratings for the desal plant and the associated pipeline by Fitch Ratings, which upgraded bonds from BBB- to BBB based on the plant’s strong operational record, updated financing projections for capital improvements, and Fitch’s expectation that the positive trend in financial and operational performance will continue.

Also this week, Moody’s affirmed its Baa3 rating for the plant and pipeline bonds. When those bonds are refinanced, higher ratings are expected to save ratepayers money by lowering the interest rate paid on the debt.

Since its inception as a public-private partnership, the Carlsbad facility has received numerous national and international awards.

The P3 approach allowed the Water Authority to develop new, capital-intensive, public-serving infrastructure without incurring debt or negatively affecting bond ratings, a fact recognized in 2016 when S&P raised the Water Authority’s credit rating to AAA citing, in part, the successful delivery of the Carlsbad facility.
