The Board of Supervisors Wednesday unanimously approved a draft version of a North County region conservation plan. A final draft of the plan is expected for board consideration by 2024 or 2025. Supervisors voted to receive the revised North County Multiple Species Conservation Plan, which according to the Parks and Recreation Department would provide the greatest environmental benefits.
Conservationists in Colorado are dreaming big. In a time of political turmoil and legislative impotence, a consortium of Colorado conservation groups is floating an audacious plan to conserve 30% of the land in the state — roughly 20 million acres — by 2030. Since statehood, the state has protected only 6 million acres.
The Federal Emergency Management Agency has taken a dramatic step to encourage communities to use environmentally friendly features such as wetlands for flood protection instead of building sea walls and levees. A new FEMA flood policy released late last month with no public announcement is drawing praise from environmentalists because it will promote mitigation projects that provide environmental benefits in addition to flood protection.
The order raises more questions about the administration’s agenda when it comes to pesticides and freshwater flows for threatened fish species.
Welcome to Climate Point, your weekly guide to climate, energy and environment news from around the Golden State and the country. In Palm Springs, Calif., I’m Mark Olalde. Intense weather and natural disasters continue demanding headline space in a year that’s seen enough news to last a decade. According to the National Oceanic and Atmospheric Administration, there have already been 16 weather events in 2020 that came with a bill for rebuilding that exceeded $1 billion.
The Vallecitos Water District is pursuing greater use of renewable resources, increasing capacity to the electrical grid, and reducing long term operational costs with an innovative solar power project.

The east array is located on top of the 40-million gallon reservoir with 2,900 modules with ten 80 kw inverters. Photo: Vallecitos Water District
In 2017, the Vallecitos Water District Board of Directors agreed to pursue development of districtwide renewable power sources using existing open space to benefit the District and its ratepayers. The District worked with solar consultants Terra Verde Renewable Partners to evaluate and study the feasibility of three solar port locations. Two projects are now moving forward; two arrays at the pair of Vallecitos owned reservoirs in Twin Oaks, and an array at the (sewer) Lift Station #1, located on San Marcos Boulevard.
The projects are structured under a Power Purchase Agreement. A solar provider designs, builds, and maintains systems for 25 years. In turn, the District receives a reduced electricity rate from SDG&E over the 25-year term at the District’s 13 highest use meters. The District will become owners of the solar system after the 25-year maintenance term expires. No capital investment is required from the District.
“The project is a great benefit to Vallecitos customers,” said Ryan Morgan, Capital Facilities Senior Engineer. “Through our export of power into the electrical grid, we receive bill credits on these power exchanges. The District benefits directly through reduced power costs, and that cost savings is passed down to the customer ultimately in reduced water and sewer rates.”
Vallecitos Water District provides the project sites, working with SDG&E, the solar provider team, the District’s contractors, and the solar maintenance operator. The District’s water professionals work with solar power experts to guide the project through planning, design, and construction as a team.
Over the 25-year term, the District will benefit from a reduced electrical rate of 7.79 cents per kilowatt-hour (kWh) at its 13 highest use meters. It will also receive a rebate or credit on its export of power to the electrical grid. Savings to the District over 25 years are estimated at $8.3 million, which ultimately results in reduced water and sewer rates for customers. District staff locked in the maximum federal rebate by launching the project in 2019 and meeting a narrow window for grant funding.

While the solar power project cannot prevent the potential for power outages due to rolling blackouts, the project helps to add capacity to the power grid when it is needed.
“The District wants to publicly thank Terre Verde Renewable Partners, Holt Renewables, and Kenyon Energy for their valuable roles in the success of this project,” said Morgan. “We also want to acknowledge the above and beyond effort of the District’s inspections team.”
The Twin Oaks Reservoir dual array is expected to be completed in November 2020. The Lift Station #1 site is expected to be completed in February of 2021.
Three fourth grade student artists were honored by the Olivenhain Municipal Water District Board of Directors at its September 9 meeting as the winners of the District’s 2020 Water Awareness Poster Contest.
This year’s theme asked students to illustrate how they “Love Water, Save Water.”
The district annually invites fourth-grade students living or attending school within the Olivenhain Municipal Water District service area to enter the contest. Because of the change to distance learning in March due to the COVID-19 pandemic, the contest deadline was extended to June 15. Six classes from the district’s service area participated.
“We have been holding this poster contest for nearly three decades,” said OMWD board member Bob Topolovac. “This year, the classroom setting may have changed, but it’s reassuring to see that the students’ creativity and excitement for water conservation is as strong as ever.”

California avoided another round of rolling blackouts Tuesday as power conservation efforts helped stave off an energy shortage while excessive heat continued to plague the state.
Water agencies across San Diego County are doing their part to stabilize the state’s power grid during this week’s heatwave by generating hydropower and altering operations to trim electricity demands – and they are offering long-term solutions to reduce future energy shortages.
The California Independent System Operator issued a statewide Flex Alert from Sunday through Wednesday, calling for reduced electricity use in the afternoon and evening to limit power outages. Blackouts could affect hundreds of thousands of San Diego County residents, if extreme heat persists.
At Lake Hodges, the Water Authority is running its pumped energy storage facility to meet peak demands. As water flows down the pipeline from Olivenhain Reservoir into Lake Hodges, it generates up to 40 megawatts of energy on demand, helping to manage temporary peak electrical demands or unplanned outages. Then, the water is pumped back to Olivenhain Reservoir when power demands are low to restart the cycle.
In addition, water agencies are taking numerous actions to conserve energy. For the Water Authority, the strategy includes temporarily reducing drinking water production at the Claude “Bud” Lewis Carlsbad Desalination Plant in collaboration with Poseidon Water.
The Carlsbad Desalination Plant is the largest, most technologically advanced and energy-efficient desalination plant in the nation, and it has produced more than 62 billion gallons of drinking water for San Diego County since it began operations in December 2015.
Starting Monday, the plant ramped down operations, making an additional 8 megawatts of power available for other uses. If more load reductions are necessary over the next several days, additional curtailment may be considered at the plant. The power provided by the plant could help offset current energy shortages.
“This partnership by the Water Authority and Poseidon is another reminder of the value of the cutting-edge technology and local control at the Carlsbad plant,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “Operations are flexible and the technology is nimble, so production can be ramped up and down in response to local needs.”
In addition, local and regional water agencies are temporarily shutting down or reducing flows at pump stations and turning off HVAC systems in the afternoons. Some agencies also have the ability to convert to less energy-intensive treatment, for instance, by replacing ozone with chlorine.
Local water agencies also are tapping their significant backup power generation capacity – at their own expense – to ease the strain on the energy grid, following Governor Newsom’s executive order that suspends some regulatory requirements for those units during this emergency event. Local agencies are also looking to work with the administration to ensure that their backup generation capacity can be used proactively to help avoid future energy shortages.
Pumped energy storage facilities are part of an integrated and sustainable energy system that
includes the production, storage and distribution of clean energy.
Beyond the immediate concerns, this week’s heat wave has highlighted the need to increase large-scale energy storage as the state moves toward a goal of 100% renewable energy by 2045. Put simply, the sun doesn’t always shine and the wind doesn’t always blow enough to meet demands, so the state needs more capacity to store peak renewable energy production for peak demand periods.
The Water Authority has proposed building a large-scale pumped storage project at the San Vicente Reservoir near Lakeside. Pumped energy storage projects are designed to store excess renewable energy from solar and wind when it’s available, and then discharge that energy when energy demands increase and renewable energy is scarce.
A 2019 white paper highlighted the importance of pumped energy storage to California’s future.
“Our current situation is the direct result insufficient planning; the state clearly needs additional energy storage now and will need much more in the future,” said Gary Bousquet, energy program manager for the Water Authority. “Environmentally friendly pumped storage projects should be started immediately to address this shortfall, or power reliability will get significantly worse. The San Vicente project can be started now at no cost to taxpayers – users only pay when the project comes online.”
Eight talented East County student artists used their creative skills to depict the importance of water in Padre Dam Municipal Water District’s annual Kids Poster Contest.
The theme ‘Water Is Life’ asked students to express the value of water in their lives. They could draw, paint, color, cut, or paste original artwork depicting the theme in any way.
Students were honored at the June 17 Padre Dam virtual board meeting online, and the youngsters were featured along with their work in a video.
“Our Annual Water Is Life Poster Contest is a great opportunity for students to learn about the importance of using water wisely and we are thrilled to celebrate this year’s winning young artists,” said Melissa McChesney, Padre Dam communications manager. “These students did a wonderful job capturing the value of water in beautiful works of art.”
