Taking Eroding Property Lines to the Bank: Creek Bank Stabilization Approaches

January 9th, 2008 by bruce_richmond

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.)

It’s in a Magazine so it Must be True: Best Places to Live in Bay Area

August 29th, 2007 by bruce_richmond

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.
