What's the real deal with maintenance at Sattva Lake Ridge?

What's the real story with maintenance charges at Sattva Lake Ridge once it's ready? The brochure numbers always look good, but I'm trying to figure out the actual per sqft cost and what's truly included. Especially concerned about full power backup for the flat, not just common areas. Also, for families, how much genuine green space is there? My wife's really focused on finding a safe, open environment for our kids, not just another concrete jungle. Anyone visited the site and have insights on these aspects? Hope this helps someone else too.
