DH I moved to just outside Seattle almost 2 years ago, and we got extraordinarily lucky. The neighborhood where we bought our house has a very active community club, and a neighbor who runs a microbrewery with regular events all summer long. We met our neighbor friends within the first couple months, and still hang out regularly.

I agree with other posters, finding community activities to take part in is a great way to meet people. Join a community choir/band/sport, go to meetups, find people with similar interests, and most importantly: exchange information. Be willing to ask people for their numbers/ social media contacts and then, perhaps the hardest part, contact them and invite them to do something with you. This may take several tries to organize something, but being willing to be the one to make plans and invite someone has been crucial to making social connections for me.
