SD County Supervisors OK Sustainability, Native Plant Policies

/in , , /by /KPBS

San Diego County supervisors Wednesday unanimously approved policies focused on environmental sustainability, and offered residents and businesses new tools to expand the natural habitat.

Supervisor Terra Lawson-Remer teamed up with board Chairman Nathan Fletcher and Vice Chairwoman Nora Vargas to propose reorganizing county departments around sustainability, including a formal plan, and creating a native plant policy to preserve regional biodiversity.

Opinion: There is No Drought

/in , , /by /Los Angeles Times by The Times Editorial Board

Gov. Gavin Newsom declared a drought emergency last month in Sonoma and Mendocino counties because of severe drop-offs in the winter rains that once had been counted on to fill reservoirs in the Russian River watershed, north of the San Francisco Bay Area. Like most other California reservoirs, those human-made lakes were built in the 20th century, an unusually wet period when compared with more than a thousand years of climate records reconstructed from studies of ancient tree rings and geological evidence.

Deepening Drought Holds ‘Ominous’ Signs For Wildfire Threat in the West

/in , , /by /NPRby Eric Westervelt

After one of the most destructive and extreme wildfire seasons in modern history last year, a widening drought across California and much of the West has many residents bracing for the possibility this season could be worse.

Anemic winter rain and snowfall has left reservoirs and river flows down significantly, even as the state experiences its driest water year in more than four decades. Today, wildfire fuels in some parts of California are at or near record levels of dryness.

Can Hydropower Help Solve the Climate Crisis? This $63-Billion Plan is Banking On It

/in , , /by /Los Angeles Timesby Sammy Roth

Conservationists in California and across the West are deeply skeptical of hydropower, and it’s not hard to see why. There’s a long history of government agencies damming spectacular canyons, choking off rivers, obliterating fish populations and cutting off access to Indigenous peoples. It’s a history detailed in books such as “Cadillac Desert,” and experienced by anyone who has spent time fishing, kayaking or swimming in the region’s reshaped waterways, or hiking alongside them.

Protect Your Hillsides and Slopes 

/in , /by

San Diego County features many native canyons, and many homes are located in proximity to a native canyon. Native canyon hillsides near your home should not be disturbed. The more you can adapt your home’s landscaping to Nature’s landscaping, the healthier and more low maintenance it will be.

Your home may have been built on canyon slopes leveled or filled. When planting in previously disturbed or built slopes and hillsides, choose low-water use plants and trees, especially deep-rooted native plant species. Climate-appropriate plants with strong root structures are the best choices. Their powerful root systems can help hold your soil together.

Coarse compost and mulch can be applied directly to hillside and slope surfaces, providing protection from the force of rainfall and shading exposed soils, if your slope is gentle with a 33% grade or less. With occasional and gentle irrigation, mulch will “knit” together.

Compost blankets are another type of erosion control mat applied to the soil surface to protect and preserve it. They can be used alone, with coir mats or other organic-engineered material with biodegradable grids for stabilization. Mats allow water to penetrate through to the underlying soils while retaining loose soil and debris, preventing erosion. You can plant right through them, or use pre-seeded products.

Irrigation tips to help preserve hillsides

Prepping Hillside for planting

When preparing a hillside for planting, plan your irrigation before doing any work. Low-volume rotating spray heads are ideal for sloped areas, if the space is large and the groundcover is uniform. Inline emitter drip tubing can also be effective, especially for wider-spaced shrubs and trees.

Water can be applied in repeated short periods over the course of 24 hours so it can be fully absorbed between application times. Runoff, erosion, and efficient deep watering should be factored into all landscaping plans, but especially for hillsides.

NOTE: When using a drip irrigation system, emitters should be placed above the plant basin. Spray systems should have check valves in all lower heads to avoid low point runoff. Irrigation for the top of the slope and bottom of the slope should be on separate valves.

This article is part of a year-long series inspired by the 71-page Sustainable Landscapes Program guidebook. The Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.

Investments Protect San Diego Region from Drought

/in , /by

It has been a very busy few weeks in the water world, with the governor declaring a drought emergency in two Northern California counties and increased discussions across the West about how to manage water through a very dry year.

While the challenges are real in some parts of the state, I applaud Governor Newsom for taking a targeted, flexible, and iterative approach to drought management. This approach provides support for individual regions that are suffering from drought while also recognizing regions like San Diego County that have sufficient water supplies due to three decades of investments in supply reliability.

Water Portfolio Strategy

The governor’s Water Portfolio Strategy aligns with our region’s long-term investments in a diversified water portfolio, desalinated seawater, conserved water from Imperial County, local water-use efficiency measures, member agency recycled water and local supply projects, and increased water storage. It’s especially important to highlight the efforts of our ratepayers, who have cut per capita water use by nearly half since 1990. Because of those actions and others, our residents have enough water for 2021 and future dry years.

In addition, the innovative and resilient water supply portfolio created by the Water Authority and its 24 member agencies puts our region in a unique position to provide solutions that can help California weather this drought and future droughts – for instance, by storing water in Lake Mead. We look forward to working with the governor and his staff to collaborate on projects and programs where we can use our assets and experience to help areas that are hit hard by drought in the face of a changing climate.

Finally, I invite you to read my latest commentary in The San Diego Union-Tribune that addresses many of the issues being faced statewide and how that impacts San Diego County.

I hope you also take a moment to appreciate the cartoon in the U-T by Steve Breen, which perfectly captures our investments over the past three decades.

Opinion: Drought-Tolerant San Diego Won’t Go Thirsty in the Dry Stretch Ahead

/in , , /by /The San Diego Union-Tribuneby Michael Smolens Quoted: San Diego County Water Authorty

San Diego takes droughts very seriously. That’s why the region is well-positioned to weather an extended dry spell with enough water.

Local officials don’t shrug at the drought conditions across the state that have triggered emergencies in a couple of northern counties. For one thing, the wildfire threat can be as dangerous here as anywhere.

San Diego may be more drought-tolerant than in the past when it comes to water, but it may never be fire-resistant.

There have been many surprises and unanticipated outcomes in the long wake of the pandemic. Like most workplaces, the San Diego County Water Authority had to quickly adapt a year ago, and that process continues to evolve under the leadership of General Manager Sandra L. Kerl. In a conversation with California Water & Power, Kerl discusses how her organization has embraced change and continues to prepare for the future.
