The highest point of terrain within 1 nm of the theshold appears to be at a distance of 3527 feet (0.58nm), 256 feet to the right of the extended centerline, at 844 feet asl. Exactly 200 feet above the runway threshold elevation of 644 feet.
Nothing particular unusual about it, there are many airports with similar "hills" in immediate runway vicinity (for example RNO). The important point is that minimum vis for this approach is 1 mile so they would clearly see all the obstacles well in advance.
