You already know how to welcome new neighbours to the community, but to get to know them better, home-centric blog Re-Nest recommends starting a Time Bank. As you help them with their DIY projects or errands, they help you with yours.

The logistics of a time bank are simple. For each hour you help someone out with their project, they help you out with yours:
Need help building a deck? Maybe catching an airport shuttle isn't in your budget right now. Enter: the Time Bank. Their Mission is, "strengthening communities through reciprocity." If you spend an hour doing something for someone in your community, that hour goes into the "bank" as a Time Dollar. You can then spend that dollar to have someone else do something for you.
While there are official channels through which you can create a neighbourhood-wide Time Bank, with a central web hub and all (so others can find it), you could always use less formal means too. Even if it just means pitching the idea to a few neighbours as a cool idea (and have them then pitch it to other folks they know in the community), you could have a pretty casual, helpful setup going. Not only is it a great way to get to know your neighbours, but you'll probably gain some good DIY experience (and maybe even learn a trick or two) in the process.
