Ground zero will put you in front of a looming structure that will hopefully give you some welcome shade during the dog days of summer. Look for the large four-digit number here. To find the final location:
DIRECTION = (NUMBER - 1147)
DISTANCE = (NUMBER + 582)
Then, project a waypoint from the starting coordinates: DIRECTION degrees at DISTANCE feet.
The cache is a short drive away, but walking is possible as well. As with all projection geocaches the final location might not be exact, but it will definitely get you close enough. Thanks, have fun, and happy hunting!
