If a creek is eroding your property, what you do to stabilize the banks can have significant unintended consequenses to your property and others downstream.

Some typical guidelines for bank stabilization approaches include:

• Do not reduce the width of the creek, as this will almost certainly cause erosion both in the bed and downstream.
• Do not reduce the length of the creek (by straightening a bend for example). This action will steepen the bed profile, increasing erosion locally, and on the next bend downstream.
• Where possible, combine grading activities to flatten bank angle and use a mixture of biotechnical methods such as brush mats and willow planting.
• Where rock is required, place rock (mechanically or by hand) rather than by dumping. Dumped rock generally forms an unsustainably steep angle, which eventually collapses and rolls rock into the creek.
• Limit the upper vertical extent of placed rock for structural and erosion protection requirements on the bank slope to maximize plantable areas. Key rock into the bed several feet to prevent undercutting.
• Utilize rock sizes based on calculations of flow force and resistance.
• Integrate native trees such as willow and alder with the engineered rock bank protection.
• Integrate native trees such as willow and alder with the engineered rock bank protection. Integrated planting has several benefits:
  • Roots anchor the soil beneath the rock, providing a living support system that increases the strength of the bank protection over time
  • Vegetation slows water velocities, reducing erosion both at the bank and downstream, and
  • Trees provide shaded cover for the creek, improving habitat conditions.

These “conceptual restoration approaches” come directly from Portola Valley’s Citizens’ Guide to Creek-Side Property Protection. The guide was created as a tool for the Town and its residents to use in guiding design, permitting, and construction of bank stabilization and revegetation efforts along Corte Madera Creek.

I know that Palo Alto and Menlo Park are looking to this an other guides for stabilizing the banks of San Francisquito Creek. It will not surprise me if other local like-minded towns (Woodside, Los Altos Hills, and Los Gatos, at least) move in this direction, too, if they can get it through the creeky legislative system. (Sorry, I had to work that in somewhere.)

Ah, Eichler homes — a truly California mix of indoor and outdoor living. But sometimes this comes at the price of dis-comfort. Many Eichler owners complain of being too hot in the summer as the sun bears down on their patio or atrium. And too cold in the winter as all that glass conducts the warm air out.

Typical home improvement suggestions to increase comfort are to add insulation in the walls and replace your single-pane windows with double-pane. Both will save energy, but lack an element of “fun” we crave. And the expense! Here are a few different ideas:

Close off the atrium or patio.

Some Eichlers wrap around their open courtyard. It’s a simple matter to add the final wall and some kind of roof covering. The roof area can be covered with an innovative skylight option. I’m a big fan of putting skylights over the atrium, because it makes the area useful during the rainy winter months, so we get more use out of the whole house. We installed a Rollamatic Roof. Our energy efficiency tests show that it doesn’t leak warm air at all. This means the glass windows facing the patio or atrium no longer conducts warm air to the outside, saving energy and money.

Oh, and the courtyard floor has now moved indoors. It can be heated with a simple add-on such as Warmfloor™. 

Add awnings for shade.

A recent study showed that shading windows on the south and west can substantially reduce air conditioning costs. While our air conditioning days are minimal, homeowners can increase comfort by shading windows and patio areas in the summer. East-facing patios, for example, can heat up in the morning and release that heat all day long, raising the house temperature in the afternoon when the sun is blazing down from the west.

Sale shades provide wonderful trapezoidal shapes for shade, a style that fits with the contemporary Eichler look. Sunset Magazine even recently featured an Eichler with a sail shade.

Add blinds to your single pane windows.

Cheaper than replacing all those famous Eichler windows with double-pane, blinds can help reduce heat gain in the summer and heat loss in the winter. Their effectiveness will depend on your lifestyle. Here are reasons that blinds may or may not work for you.

First, blinds reduce heat gain and heat loss when they are closed. But, as Eichler owners, we like our open indoor/outdoor feeling. So, blinds depend on the good habit of actually pulling them down. Will you really do it?

Second, blinds are an imperfect seal. They let hot air in, and cold air out. They will reduce heat transfer, but not as effectively as a double-paned window. Will you mind? If blinds are a solution for some of your windows, look for those that have R values (insulation factors) of 2 or more.

Match your choice of blind to your purpose. Some styles are optimized to save heat in the winter. Other styles are optimized to provide shade in the summer. There are even shading blinds that you can look through, keeping the best of both worlds — Eichler’s feel of outdoor living while cooling the house in the summer.

I love living in my Eichler, but I want to save energy too. Let’s keep looking for fun ways increase comfort.

When it comes to climate change, most schools get a failing grade.

But first, let’s look at the big picture, which shows a growing interest in building greener schools. Sixty schools across the U.S. have been certified by the U.S. Green Building Council, and 360 more are waiting to have applications approved.

There is a movement towards greener practices, too. Residence halls and dorm rooms are sporting energy-efficient mini-fridges and low-flow shower heads, among other eco-products for the generation used to sorting trash.

Locally, the Bay Area Green Business Program lists only four schools in Santa Clara County that they’ve certified as “Green.” San Mateo County started it’s program during the latter half of 2007 and is not yet certifying schools.

Stanford University is no surprise on the list. Stanford Dining received the first Acterra Award for Sustainability. They were a runner up in Grist’s 15 Green Colleges and Universities. They’ve embarked on a fascinating multidisciplinary Initiative on the Environment and Sustainablility. Lots of cool stuff going on at Stanford.

Palo Alto hosts two green schools: Castilleja, a private girls middle and high school on Bryant Street, and Gunn High School on Arastradero Road. The only elementary school is Sunnyvale’s Cumberland.

I guess as parents and teachers influence the schools, more environmental awareness will pass through the school. Then, the kids will be teaching us how to take better care of the planet we’ll be leaving them.

San Jose Magazine sure likes “best of” lists. According to the teaser on the Aug 07 cover, they’ve picked the top “cities and neighborhoods to consider moving to when buying a home and selecting a good school district for our kids.” That’s it. No overall criteria explained inside, as far as I could see.

However, there is a well-written individual description for each of these Best Places to Live selections. I added SJ mag’s sub-header to the names on the list to keep it interesting and entice you to look at the description, so here goes.

Atherton: Elegant gardens and native trees dominate this quiet small community.

Lovely homes on tree-lined streets have made Burlingame the “City of Trees.” (Trees and nature are mentioned throughout the descriptions of these Best Places.)

Campbell is a quaint community where tradition and progress go hand-in-hand.

Founded as an artists’ colony, Carmel is as inspiring and beautiful as it was more than a century ago. (The only coastal city on the list and the only one in Santa Cruz County.)

Diversity and high-tech innovation abound in Cupertino. (Schools are a regular highlight in these cities’ descriptions.)

With plenty of shopping, employment and recreational opportunities, Fremont captures metropolitan living at its best. (The only East Bay city listed.)

One of the fastest-growing cities in Silicon Valley, Gilroy is open for business.

Hillsborough: A great small town in which to lead a lavish life.

Tree-lined streets and a small-village atmosphere liven up Los Altos. (“Small town” feel is another feature prized by the group creating this list.)

Los Gatos: A small-town feel and rich history can be found in this bedroom community.

Milpitas: This forward-looking city is a vital part of the Valley’s economy.

The city might be tiny, but Monte Sereno is awash with beauty and rural charm.

Thoughtful planning has made Morgan Hill one of the Valley’s most desirable communities. (Valuing the past while planning for the future seems to be another key to getting on this list.)

Mountain View offers homes and amenities suited for every lifestyle.

Palo Alto: The “Birthplace of Silicon Valley” is a blend of old and new.

There are countless reasons why business and citizens choose to locate to Santa Clara.

Community pride and a rural feel separate Saratoga from Silicon Valley.

Woodside: A place to find small-town life at its finest.

San Jose neighborhoods:
Residents retreat from nearby Silicon Valley to the relaxing Almaden Valley.
Families build their future in the developing Evergreen Valley.
Rose Garden: San Jose’s historic neighborhood cultivates its turn-of-the-century beauty.
Hidden in the foothills, Silver Creek is sheltered from the chaos of Silicon Valley.
Willow Glen: A neighborhood that retains its unique identity in spirit and architecture.

There are no surprises on the list. This really is a great place to live.

With all the interest in green homes, it’s not often one comes on the market. That changed yesterday, with a beautiful, century-old Craftsman now for sale at 120 Waverley Street in Palo Alto. This home blends the character of an old home with modern comfort and conveniences.

A Palo Alto firm Topos Architects remodeled this home following LEED Residential standards. They claim that, had the rating been available when the home was completed, it would have qualified for a LEED Gold rating.

How does this home qualify as being so green? Much of the existing building material was re-used within the remodel. Recycling efforts for the unusable material far exceeded Palo Alto’s requirements to minimize landfill.

Energy efficient design exceeds the California Energy Commission standards (Title 24) by 3%, reducing the owner’s energy consumption and utility costs. This is enhanced by passive solar design and tracked through an innovative Agilewaves resource monitor, making it a smart house as well.

Building components that create the energy efficient envelope include highly rated windows, exterior doors, and insulation. Interior energy savers include the furnace, air conditioner, ventilation fan, water heater, toilets, and lighting with a lighting control system. Energy Star rated appliances (refrigerator, clothes washer, and dishwasher) add the finishing touches.

If you’re ready to move into a green home, the $3.15 million price tag is a good value for the neighborhood. If you’re a do-it-yourselfer, there’s a tear-down in a nearby neighborhood for almost $2 mil. You can still have your green dream home – it will just take longer to move in.

It’s almost the end of class and towers of cardboard cover the tables and floor. Students have been learning the importance of a wide base to have a waist-high structure.

That may not seem like a tall order for most of us, but these students are five to seven years old. The class is Architectural Design for Kinders offered by Palo Alto’s Community Services Department as part of the summer program.

German native Anja Blum is an incredibly patient and encouraging instructor. She gets a little help from the few parents who stick around and help their child. An architectural designer herself, this is Anja’s first year teaching Kinders. Architectural Design for Kids (7-12 years old) is in its third year.

Through drawing and model making, Kinders learn concepts such as floor plan, elevation, stability, and interior design. The Kids class adds concepts such as scale, three-dimensional design, and designing furniture.

The most important goal is that they have fun working with the materials as they manipulate small boxes, construction paper, pipe cleaners, yogurt containers, toilet paper rolls, craft sticks, wire, strawberry baskets, scissors, tape, and glue.

It’s not be the Magic School Bus, but with these hands-on experiments, they certainly get to “take chances, make mistakes, and get messy!”

I see gray piles of crushed concrete as I’m driving by construction sites, looking like gigantic abandoned sandbox projects. We’re likely to see more of these piles as green concepts permeate the building industry.

According to the Concrete Network, recycling concrete from demolition project can result in considerable savings since it saves the costs of transporting concrete to the landfill (as much as $ .25 per ton/mile), and eliminates the cost of disposal (as high as $100 per ton). This savings to the contractor also results in greater environmental benefits, such as protecting natural resources, fewer pollutants from the transport of materials and reduced impact on our landfills.

Palo Alto’s “construction and demolition” program requires 90% of concrete and other inert solids be diverted. Santa Clara requires 50% to be recycled. San Jose, most of the cities within San Mateo county (and the County itself), and nine cities in Alameda county have also implemented these reuse and recycle programs.

Recycling of concrete is a relatively simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. The goal of a green remodeler is to use as much onsite as possible, says Iris Harrell of Harrell Remodeling.

Concrete Technology gives five applications of unprocessed recycled concrete, then five different applications after processing, including new concrete. So concrete really can be recycled into more concrete!

The photo is at 3270 West Bayshore as seen from 101. Other concrete piles can be seen at 899 Charleston and at Page Mill and Park. All are in Palo Alto.

What did you do during your summer vacation? PACCC’s Neighborhood Infant Toddler Center was treated to a makeover. NITC is in a 50 year old adobe stucco house in Old Palo Alto a few blocks from Bowden Park.

Gratitude was appropriately heaped upon the parents, staff, and contractors for their support during the structural and cosmetic upgrades. Bob Davis and David England of Spectrum Fine Homes listed in the thanks. I know these guys and with their dedication to green construction, you can be sure that NITC has become greener.

Also thanked for their “quality and tireless hard work” were RJ Leonard Painting of San Jose, Economy Hardwood Floors of San Jose, Western Exterminator, Art-Craft Carpet and Linoleum Shop in Palo Alto and Timothy Andrew, aka “Handy Andy.”

In case you are not familiar with PACCC (Palo Alto Community Child Care), it’s one of the numerous options for preschool and after school care in Palo Alto. Not limited to Palo Alto residents, it’s a non-profit corp originally created out of Palo Alto’s desire to provide comprehensive child care covering ages two months to fifth grade.

My family gives special thanks to Cara Whaley and her staff at Barron Park Children’s Center, to Mary McCalister and Linda Jackson at Sojourner Truth Child Development Center in the Ventura neighborhood, and to Infant/Toddler & Preschool Coordinator Lisa Rock, who was always helpful and easy to talk to. Additional thanks and congratulations to Lisa Lewis who was Center Director of STCDC when we started and has been promoted again, this time to be PACCC’s Associate Director.

So where are all of these Backyard Habitats?

Apparently, it’s a bit labor intensive to get the Certified Backyard Habitat stats city-by city. Thanks to Roxanne Paul of the National Wildlife Federation for sending this partial list before dashing off on her vacation.

Campbell: 12
Cupertino: 9
Los Altos: 16
Los Altos Hills: 3
Los Gatos: 14
Menlo Park: 4
Palo Alto: 17
Saratoga: 5
San Jose: 99
Santa Clara: 9

Landscaper Sherri Osaka told me today that she had one and they’re not that hard to do.

I recently talked with a neighbor in Palo Alto who’s really into animals. I asked if their backyard landscaping was completed. She showed me how the family had “gone wild” to reintroduce native tree frogs and toads to the environment with their new pond and supporting vegetation.

This family is not alone. The National Wildlife Federation has certified over 80,000 Backyard Wildlife Habitats nationwide. There are 77 certified in San Mateo County and 237 in Santa Clara County

It seems we can create a landscape that incorporates locally appropriate planting for wildlife and human habitation. Locally-developed Sustainable Landscape Standards give wildlife habitat one point out of 49. The fascination factor is much higher. It is not as difficult as you’d expect to help support wildlife in your backyard. My neighbor incorporated a water feature in the garden for birds and other animals, including local fish. The downside may be that the local egrets eat the fish.

Another gardening for wildlifesuggestion is to provide food, shelter, cover, and water for wildlife such as mammals, birds, hummingbirds,, beneficial insects,bees, andbutterflies You can pick and choose what you want to attract. No one will convince me to support my yard’s ant population.

A third, obvious choice is to eliminate pesticides whenever possible by using integrated pest management practices to preserve native insects, birds, and other small creatures.

At the end of my backyard tour, half joking, I asked my neighbor, “What’s next, bats?” Apparently, the bat houses are already ordered and should arrive by end of summer.
