Seems to be a theme... developers buying right next to or behind longstanding gun ranges[which were built when they were out in the country] and suddenly there are [reportedly] a bunch of rounds exiting the property. I think the reality is that they bought the land at a discount for the noise and "perceived danger" and play it up as if they saw a bunch of splashes in their construction site to turn it back into a big money making development.
I know nothing about this particular range but the theme is real.
