Rain gardens are a decent first step. In moco, you can even get a big rebate to put one in if you are willing to work through the bureaucracy to get it approved first.

Traditional storm water management has been dump the water into the sewers and move it somewhere else. That doesn't scale well as some have noted in this area with flooded streets when it rains. That strategy also tends to wash surface contamination into the nearest body of water without any treatment. So, silt and oil wind up in the river.
So not something the average homeowner can do, but a good technology to be aware of. I wonder why there aren’t more of these in California? I guess the rain is just that uncommon in enough of the state, whereas Washington gets a lot more rain.
OP you probably can’t do/don’t need one of these (or at least not in the average suburban or DC townhome lot), but you might be able to get a rain barrel or two. They have screens on top so mosquitos don’t lay eggs in them, and then you have 50 gallons of water for watering.
It's not easy to do with hand tools IMHO. You also need to do some calculations to determine the capacity you need.
Collecting rain water has a questionable legal status in some states. Go figure. https://worldwaterreserve.com/is-it-illegal-to-collect-rainwater/

Someone on another thread said we should all be doing this. Can you provide more detail? I think if I dig a trench I’d just have a muddy hole. Please explain. Thanks.
