There is no official teepad for #13 or #15.
13 basket is in a temporary spot. Its an easy little pitch downhill from near the green power box on the ground, near the sidewalk.
Most course regulars choose to simply skip this hole.
It will be relocated to a more permanent spot sometime in the future.
So this is how you play those holes.
After you finish #11, the flat hole along the gravel path, follow the path northwest, cross the lower portion of the 18th fairway, then walk up the two zigzag switchbacks. At the top of the switchback path, on your right, is the tee for #12.
The basket is on the top of the hill, just to the right of the large storage containers.
From #12, follow the now easily seen bark path on your right, 20 feet, to the #14 tee.
#14 basket is past the basketball court, but well to the right of it, on a knoll.
After #14, look for the path going downhill, on the north side of the basket.
The tee for #15 is at the far northeast corner of the dog run area, in the gravel lot.
Look for a footline drawn in the gravel there, or possibly a stick. The basket is south from here. The large tree on the left side of the fairway, just past the road, is a mandatory. Your drive must be on the right side of this tree.
So aim between the concrete compost bin, and this tree.
After #15 walk north, back up the fairway, to the new, elevated #16 tee.
