Sometimes people relocating to Silicon Valley tell me that they’d like to move to a waterfront home, something with a view of the Pacific Ocean or the San Francisco Bay. Most of Silicon Valley is inland, though, separated from the ocean by the coastal mountains.
Ocean View Homes
For those truly set on having a view of the Pacific, home can be found in the Santa Cruz area with lovely ocean and Monterey Bay views. The compromise will likely be a long, winding commute over Highway 17’s mountain pass.
Similarly, ocean lovers may settle close to Half Moon Bay or Pescadero, but will have to slog over the coastal hills on Hwy 35 each day to get to the Peninsula. (Some lucky souls may find employment in Scotts Valley or along the coast, but most of the jobs are not in these places.) If faraway ocean view will work, a home in the Santa Cruz Mountains may be the ideal fit.
Silicon Valley Waterfront Homes
If you want to live along the waterfront within Silicon Valley and not these neighoring communities, there really are not a lot of neighborhoods from which to choose. Most water-view homes involve the San Francisco Bay. There are a few rivers, creeks, ponds (mostly man-made or percolation), lakes, and reservoirs to be found as well, but enjoying lovely water views up close is not the easiest criteria to fill and each come with their own concerns. Waterfront bay views often come down to Foster City and Redwood Shores, which we’ll discuss next. (more…)
What are the natural hazards in the San Francisco Bay Area and Silicon Valley?
The main natural hazards to consider are:
- 100 or 500 year flood plains
- floods from dam failure or levee failure (includes rising sea and bay water levels)
- liquefaction zones (and compressible soils areas)
- landslide zones
- fire risk areas, such as the Very High Fire Hazard Severity Zone
- for those with basements (few homes), radon
There are zones associated with these potential risks and those areas are delineated by the state, county, and local jurisdictions. The state level earthquake faults are those which are considered active in relatively recent years. The county mapped fault zones may not have been active in over 10,000 years and the town or city labelled areas have been dormant for much longer than that.

Fire season is a concept we are familiar with in the West Coast, but it may be foreign to those moving here or living far away.
Not long ago I was on the phone with a cousin from the East Coast. That area had recently been hit by Tropical Storm Ida and over here we were being smothered by the smoke from the Northern California fires (Caldor, Dixie, Tamarack and some others). Aghast at enormity of it all, my cousin asked the poignant question, “has there always been a fire season, or is that a recent thing?”
Briefly, yes, California has always had a fire season.
One major reason people (myself included) love California is for its mostly dry Mediterranean, subtropical climate. However, that ideal dry hot summer climate is also a perfect tinderbox. Without summer rain, the grasses and annuals die off and many native perennials go dormant. Dry hot winds, frequent from around August through October, dry out the landscape even more. By this time, an open hillside is A-grade kindling – one little spark and it’s a recipe for disaster.
Even in wet seasons with no drought, the summer will always be hot and dry with a high risk of ignition. So while fire season is nothing new, it’s longer and much worse than it used to be.
Fire and California Homes
For California homeowners and buyers, the increasing fire danger is strongly felt. Most buyers tell me they do not want to be in high fire risk zones, but might not always know what to avoid. State and local governments have put more preventative regulations in place to keep homes safe from wildfire, both on builders and homeowners.
If you are relocating to Silicon Valley, you may be wondering what the risks of wildfire are like for this area. There are plenty of resources available online, and I always recommend clients to look at the hazard maps such as those listed in my article Tools You Can Use When Relocating to the San Jose Area. While the mountain and foothill communities may be at risk of wildfire, even the lowlands are experiencing another concern that comes with harsher fire seasons: smoke and air quality.
In my other blogs I have more articles dedicated to the topic, so I won’t go into detail here. I encourage you to view some of my articles about Fire at the Live In Los Gatos Blog or over at the Valley of Heart’s Delight blog under the Natural Hazards and Safety categories if you’re interested in learning more.
Some of the oldest trees living in California have the scars of past fires, sometimes multiple. Native plants have evolved and adapted to fire and can thrive in its shadow. And for as long as people have lived here, they have contended with seasonal fire danger.
Fire season 2021 has come to an end with the arrival of rain – a double bounty since we are in the middle of a severe drought. When the rains come, the problems aren’t over, though. In burned out areas, the next challenge will be mudslides and further damage to the fire zones. This is an old problem also, I remember hearing about the mudslides following the fires as a kid growing up in the 60s and 70s.
“Fire hardening” is an important concept for those of us who live in or near large open spaces with hills especially. I suspect it will grow into a cottage industry with new experts appearing to advise or possibly install features which will make our homes and landscaping more resistant to advancing flames.
Water Heater improperly strapped – lower strap should be 4″ from controls – wise to fix this to make it more safe in an earthquake
If you are moving to California, or have recently arrived here, you are no doubt aware that this is Earthquake Country. There are modifications to the residence that can be done to improve earthquake safety, both inside of the home and in the structure itself. Is your home safe in an earthquake now? If not, it’s always a good time to address it, as quakes are a frequent occurrence here.
General tips and resources
Most injuries from quakes happen things falling on someone, so there’s a great focus on indoor precautions, such as securing book cases and tall pieces of furniture to the walls by bolting them securely in place, strapping water heaters, and so on. If you do a web search for how to make your home earthquake safe or ready, you will find many tips along these lines. If you aren’t familiar with these tips, here is one to get you started:

Required disclosures in California
When you buy or lease a home (for 1 year or more), you are supposed to receive the mandated Homeowner’s Guide to Earthquake Safety, print or digital, as well as information on mold, lead paint, etc. Both the state and also many companies provide these regulatory disclosures, and they are worthwhile reading for anyone living in the Golden State especially. If you implement the home improvement suggestions in these pamphlets, it could not just make your home safe in an earthquake, it could save a life.
Additionally, home owners need to provide a statement they’ve completed regarding earthquake hazards and what is known about them to buyers or those who will lease for 1 year or more. You can see that form here: Residential Earthquake Hazard Report. The questions were written by the state of California, so they are not 100% intelligible to consumers, however, submitting a query to any of the major search engines can provide results on what questions are being asked. Please read and learn to understand what the questions are asking, as they all pertain to safety issues, which for most of us would be paramount.
Sometimes I see sellers answer “don’t know” to every question on the form. That is not helpful. Most sellers do know if their water heater is strapped, and if they have done a pre-sale inspection, the inspector will have told them if the strapping is correct or not. If they don’t know what a cripple wall is, a quick search will tell them whether that question applies at all – and often, it doesn’t. Most houses here do not have brick (aka “masonry”) foundations.
Earthquake safety and soft story construction
Question 7 reads of the form listed above says:
If the house has a living area over the garage, was the wall around the garage door
opening either built to resist earthquakes or has it been strengthened?
Soft Story Condos – living area over a garage or carport
A a garage or carport with a living area above it is called a soft story (sometimes spelled soft storey) and is more vulnerable to damage from earthquakes because of the large opening at the garage door. This could be a house, a townhouse, a duet home, a condominium, etc. – anywhere there’s a living space over a parking space with a wide opening for cars to pass through. In some cases, there’s only a little overlap between the parking area and the living area above. In others, there are 2 stories above, and no dividers between the carports, so there are a lot of gradations to it. Newer homes, of course, have been engineered better. (I think you are unlikely to see the open carport style in newer construction.)
We see that configuration all the time, yet many people do not understand the vulnerability or that they might want to address it. You can see some scary pics by doing a Google image search for Soft Story Earthquake.
Living area over separate garages
It is possible to improve safety by strengthening or reinforcing the areas on each side of the door frame (if there IS a door frame, sometimes it’s an open carport), and perhaps additional areas, too. The same issue would be at play if you were in a home over a shop with large display windows and not much solid wall directly below you. A structural engineer can give the best advice on home improvements that will make the structure safer in case of a quake.
In some parts of California, there’s a movement to get apartment and soft story building owners to retrofit buildings. Palo Alto has been discussing it in recent years. Los Angeles has been requiring the retrofitting for seismic safety of many buildings mandatory for a couple of years now.
That could be a significant cost but would no doubt save lives in the event of a major seismic strike.
If you are going to purchase a home with a living area over the garage, or have already done so, see if you should bolster the engineering for safety. Some improvements may not be costly, so don’t dismiss it as unfeasible without investigating. If you own a condo with a soft story ground floor, learn what can be done to strengthen the building so there is a lessened risk of collapse.
There are many more issues to making your property more safe in an earthquake that we didn’t touch on here today. Be sure to ask your home inspector or structural engineer how you can make your dwelling more earthquake resistant and more safe in case of shaking and related issues. Read the state guide, linked above, which has great information that every California resident should know.
