California flood protection starts giving rivers more room 

Ellen Knickmeyer, ASSOCIATED PRESS

After more than a century of building levees higher to hold back its rivers, California took another step Friday toward a flood-control policy that aims to give raging rivers more room to spread out instead.

The plan, adopted by the flood-control board for the Central Valley, a 500-mile swathe from Mount Shasta to Bakersfield that includes the state’s two largest rivers and the United States’ richest agricultural region, emphasizes flood plains, wetlands and river bypasses as well as levees.

Backers say the changing strategy will better handle the rising seas and heavier rain of climate change, which is projected to send two-thirds more water thundering down the Central Valley’s San Joaquin River at times of flooding.

The idea: “Spread it out, slow it down, sink it in, give the river more room,” said Kris Tjernell, special assistant for water policy at California’s Natural Resources Agency.

Handled right, the effort will allow farmers and wildlife — including native species harmed by the decades of concrete-heavy flood-control projects — to make maximum use of the rivers and adjoining lands as well, supporters say.

They point to Northern California’s Yolo Bypass, which this winter again protected California’s capital, Sacramento, from near-record rains. Wetlands and flood plains in the area allow rice farmers, migratory birds and baby salmon all to thrive there.

For farmers, the plan offers help moving to crops more suitable to seasonally flooded lands along rivers, as well as payments for lending land to flood control and habitat support.

In wine regions, vineyards and conservationists battle for the hills

Alastair Bland, YALE ENVIRONMENT 360

Kellie Anderson stands in the understory of a century-old forest in eastern Napa County, about 70 miles north of San Francisco. To her left is a creek gully, a rush of the water audible through the thick riparian brush. The large trees here provide a home for deer, mountain lions, and endangered spotted owls, while the stream supports the last remnants of the Napa River watershed’s nearly extinct steelhead trout.

“They want to take all of this out,” says Anderson, who sits on the steering committee of a local environmental organization, Save Rural Angwin, named for a community in the renowned wine country of the Napa Valley. She is studying a project-planning map of the area as she waves her free arm toward the wooded upward slope. “It looks like this will be the edge of a block of vines,” she says.

Anderson and two fellow activists, Jim Wilson and Mike Hackett, were visiting a property of several dozen acres that the owners plan to clear and replant with grapes, the county’s principal crop. The project is one of many like it that are now pending approval by Napa County officials, who rarely reject a vineyard conversion project in the Napa Valley, a fertile strip that runs northward from the shores of San Francisco Bay.

In Napa County, neighboring Sonoma County, and farther to the north in the Willamette Valley of Oregon, concern is growing among some residents, environmentalists, and scientists about the expansion of vineyards into forested regions and the impacts on watersheds and biodiversity. In Napa, an aerial view reveals a carpet of vines on the valley floor, which is why winemakers hoping to plant new vines increasingly turn to land in the county’s wooded uplands. At these higher elevations, “about the only thing standing in the way of winemakers are the trees,” says Hackett.

Wildlife-friendly fencing catching on across Sonoma County

Landowner’s guide to fencing

Creating a wildlife-friendly fence

Have you ever watched as a fawn, a coyote or a quail scurries in a panic to find its way around, over or through a fence?

Fences of all descriptions crisscross Sonoma County, and they are a major obstacle for animals simply trying to find food, water and shelter.

There are literally thousands of miles of fence in the county, built for many different purposes: for privacy, to keep pets or livestock in, to mark boundaries, to protect crops, to keep deer out, to protect property from vandalism, to keep animals from entering roadsides. There are many types of fences, some that allow wildlife to safely pass through while others that are actually quite hazardous.

According to those who have researched this issue, the most lethal type of fencing is woven-wire, with one or two strands of barbed wire over the top. These fences block smaller animals from crawling underneath, and often snare one leg of animals like deer that attempt to jump them.

Perhaps you’ve seen the remains of a doe or fawn that has met its fate in this manner, left to die dangling from one foot on the far side of the fence. In fact, one study in Utah found that fawns accounted for 90% of the mortalities on woven wire fences.

These are uncomfortable realities, but ones that many different land owners and land managers are confronting. We are doing out part at Sonoma County Regional Parks, working with partners and volunteers to remove old fences in places like Sonoma Valley Regional Park. The best fence often is no fence at all.

We also are working to replace old barbed wire fences with new ones that have smooth wires on the top and bottom, none of which is more than 40 inches tall. They adhere to guidelines set out by the Sonoma County Agricultural Preservation and Open Space District, and mirror those being used all across the West.

These wildlife-friendly fences allow us to keep cattle in where we want grazing for natural resource benefit, while allowing wildlife safe passage.

Wildlife-friendly fences benefit a wide range of animal species, including large carnivores like mountain lions, wide-ranging omnivores like black bears, smaller predators such as badgers, and even raptors and upland game birds.

Science is helping us discover which Bay Area lands are most important to wildlife as it passes through. By analyzing the areas where that movement is concentrated — streams and ridgelines and areas that still are relatively undeveloped — several maps have been drawn that indicate priority areas for conservation.

While they are helpful, it is important to recognize that micro linkages exist along every small waterway and ridgeline throughout the county. Much can be done at the scale of small farms, individual homes and backyards to address wildlife connectivity.

The most important thing you can do in your own yards is to consider making enclosures as small as possible to meet your needs. Rather than putting a deer fence around the entire property, for example, focus just on your garden space. If you have wilder portions of your property along streams or wetlands, consider removing all fencing that is nonessential.

Sebastopol’s Atascadero Creek has a rich history

Arthur Dawson, THE PRESS DEMOCRAT

Atascadero Creek flows from its headwaters southwest of Sebastopol under Bodega Highway through Ragle Ranch Park and continues north to meet Green Valley Creek near Graton. One explanation for its name is that it’s a native word meaning “dirty water” or “lots of water.”

In Spanish, atascadero means “bog” or “marsh,” a place with “lots of water.” An atascadero also can be a bottleneck or stumbling block, something that impedes progress. Atascar, the verb, means “to be stuck,” and an atasco is a “traffic jam.” We use the same metaphor in English when we get “bogged down with the details,” when moving forward feels as painfully slow as slogging through mud.

It’s probably no coincidence that Atascadero Creek once watered an extensive wetland above its confluence with Green Valley Creek. That marsh captured water in the winter and released it slowly through the dry summer (which may account for how Green Valley got its name as well). Before pavement and bridges, that atascadero would have been a place to avoid on foot or horseback.

Like most wetlands in California, those along Atascadero Creek have suffered. Early maps of Sonoma County show that significant changes to our watersheds were already underway by 1875 — wetlands drained, creeks rerouted, channels dug — all done with only the power of men, shovels and sometimes horses. This trajectory has continued up to today, though the machinery has become more powerful.

Several endangered species make the Atascadero Creek watershed their home, including steelhead, freshwater shrimp and the Pitkin marsh lily (which grows in a marsh on a tributary of the main stem). Coho salmon were present in the past but have not been seen recently. In 1998, the state designated 44 acres as the Atascadero Creek Marsh Ecological Reserve. Its mix of riparian forest and seasonal and permanent wetlands draws large numbers of water birds, raptors and passerine species (also called songbirds).

Local groups like the Atascadero/Green Valley Watershed Council and the Friends of the Atascadero Wetlands are focused on protecting and restoring more of the wetlands. A study is underway that will help protect them under the County General Plan. The atascadero for which the creek is named seems to be undergoing a transformation from obstacle to opportunity. Pausing by a marsh, even along the road, is a chance to slow down and tune into what’s right in front of you. You may even forget where you were going.

ACTION: General Plan Amendment proposal for Atascadero Creek wetlands

Rue Furch, SONOMA COUNTY GAZETTE

Atascadero Creek near Graton has marshy wetlands that are home to dozens of species of birds and wildlife. Wetlands store water during winter rains and release it into the underground where it supplies water for our wells.

HELP PROTECT THIS NATURAL RESOURCE!

On May 5, the County Planning Commission will decide if these wetlands should be included in county planning documents. If they vote “yes,” it will mean “hands off” to vintners, developers and builders who want to fill or plant or dredge these critical areas.

SHOW UP AND SHOW YOUR SUPPORT!

LET THE COMMISSIONERS KNOW OUR WETLANDS ARE IMPORTANT!

MAY 5, 2016 – 1:00 P.M. 

PERMIT AND RESOURCE MANAGEMENT DEPT. 2550 Ventura Ave., Santa Rosa CA 95403 

FYI: County schedules can change at the last minute. Call the Planning Department at 707-526-1900 the morning of May 5th and ask if the Atascadero Marsh Wetlands study is still on the agenda.

A proposed General Plan Amendment to expand wetland designations for the Atascadero marsh area is to designate the Atascadero wetlands, and add the Biotic Habitat (BH) combining zone which will help protect this sensitive habitat area from future development and impacts from agricultural, orchard and vineyard uses.  The proposed changes would provide a 100 foot setback from potential wetlands.  The purpose of project is to enhance protection for natural habitat, especially wetlands that adjoin the already protected riparian corridor along Atascadero Creek.

The proposal is to designate the wetland areas on the Opens Space maps with the BH combining zone.  The general plan requires a 100 foot setback for discretionary projects from designated wetlands.  VESCO also requires a 100 foot setback from wetlands designated in the General Plan.  So the protections would apply to discretionary projects (wineries, etc) and orchard and vineyards.  The Ag Commissioner has BMPs for other ag that may consider designated wetlands.

The planning commission hearing is set for May 5th, 1:00.  The staff report should be available the Friday before the PC meeting (April 29).

Sonoma County coalition awarded $8 million grant for water conservation work

Mary Callahan, THE PRESS DEMOCRAT

Supplemented by local funding, the venture aims to boost stream flows and groundwater and clean up the Russian River and its tributaries.

A coalition of Sonoma County resource agencies has been awarded $8 million in federal funds to advance an ambitious series of conservation projects intended to improve water supply and quality and enhance wildlife habitat on local agricultural lands.

The efforts will take in vineyards and farmland and aim to reduce erosion, boost stream flows and groundwater and clean up the Russian River and its tributaries while restoring habitat for imperiled fish and wildlife species.Sonoma County’s Agricultural Preservation and Open Space District is the lead agency and will contribute $14 million of the $15.8 million local match for the U.S. Department of Agriculture grant.

Most of the funding will go toward the purchase of conservation easements on farmland along key stream corridors and in areas where flood plains and groundwater basins can benefit.

One objective is to fortify the water supply for growers and wildlife in the face of drought and amid the uncertainty posed by climate change.
