From my knowledge, this hill is actually artificial, since it is just north of Foster City, Mariners Point. The park consisted of a dog park, a trail, as well as the hill which is used for runners, and the Stairway. This stairway might be the most shocking yet, since it is just 7 miles south of my hometown. All these years I never knew this stairway existed. That is until my sister had mentioned that she saw some stairs at the dog park. Unable to tell me the name of the Park, I did some research online and actually found this fantastic stairway through google earth. It's much better in person though, trust me.
