It's a bit of artificial landscaping between an office building and a parking garage, but it looks and sounds authentic. The photo is not too sharp because I broke some rules: 1/13 sec at 200 mm with no tripod.
The viewer wouldn't know it wasn't somewhere in the mountains. It's a lovely shot. Nice that they are putting such soothing sounds in office buildings and parkage garages. Calms one down before and after the work day!
