Every neighborhood has a low point. That’s usually a good place for a neighborhood park with a rain pond. Currently, stormwater management engineers would build a retention basin there and put a chain link fence around it; don’t let them do it because those things are hideous and fill up with junk washed in during a storm. Let it be a pond that holds water instead, and which people can enjoy. It does the very same jobs the engineers were looking for of slowing runoff and recharging groundwater, but it does those jobs beautifully.
