That's the most ridiculous thing I've ever heard.
So you're going to lower the temperature in the area
by wasting water on a lawn. What a gass!

You may think it's a "gass", but it is an effect in a
large enough urban area. Look up "microclimate".

Las Vegas has been changing (getting more humid) due to all the water spread
around in the desert by people that want to bring lawns with them. Just
because you CAN do something does not mean it is a good idea.
