My city is fairly large and their recreational projects usually have budgets in the 10s of millions. I don’t think there is much I can do on that front. That being said, I think this question could be better framed as “to make your community a better place to live”. From that angle, I would have to get in touch with my HOA (I know) and see about opening a community garden with that initial investment.
Scatter random tire spikes on the roads. 10k would probably get you quite a few
Wow that would kill a lot of people where I grew up. Very efficient.
You are overestimating the danger of a punctured tire. It is easy to notice, usually gives you plenty of time (on the order of minutes) to come to a complete stop before the tire is deflated, and even after the tire is fully deflated it still allows you to stop relatively safely for a short while (until it is cut through completely). It would probably result in a few crashes (because in carbrained places many drivers don’t know how to operate a vehicle at all), but the worst outcome from this is ambulances/firetrucks being stuck in traffic jams.
Donate it to the library or a local food bank. Simple community building.
I’ll echo food banks. $10,000 isn’t much money for a municipality of more than 100 people, but a food bank might be where that money goes the furthest.
Knowing from my local outfit, while they would of course accept a donation of actual food bought with that money, they can do much more with the money than the food it buys in the grocery shops.
They do that by reaching out to vendors themselves and getting discounts that would put Costco out of business. I once heard that monetary donations being stretched 5x is typical, oftentimes going 10x or more.
