Mountains Aren't For Everyone
Living on the other side of the "hill" comes with some drastic lifestyle changes. Here's what you can expect when taking up this move: It might seem like you're just a few miles from bigger cities (San Jose is about 25 miles from Boulder Creek), but the reality is that even when the roads & weather are great, its not a short trip. Mountain roads have twists and turns, they go around the topography of the mountain. Generally speaking, you're rarely going to be able to drive above 45mph on most roads. No to mention during rainy winter seasons, mudslides and downed trees can also block off roads (sometimes for more than a day). This is a make or break situation for most people, so ask yourself: are you okay with a ~60min commute on mountain roads vs Hwy 101?
Utilities are also different compared to what you'll find in the Bay, and very location dependent. While you'll likely still get electric service from PG&E, water, sewage, and internet service will all likely be different than what you are used to. Internet service is very location-specific, and you can wave goodbye to Fiber fast speeds. Comcast has spotty coverage in the mountains, or you may need to purchase satellite internet, which is admittedly slower speeds, high latencies and has potential for outages whenever the weather isn't perfect. Cell phone coverage is also a huge variable, it can change every few feet due to the terrain. Make sure the area you are interested in has the internet connection and cell service you need.
