They didn't raise it only eight inches because they simply felt like it and picked a number out of their hat - eight inches was the most they could do without also impacting a nearby level crossing. Ballasting plain track up to a higher level can be done relatively easily (up to a certain extent of course), whereas touching the level crossing requires more work and also creates problems with the road geometry there:
If you raise the track across the level crossing too much, you create a nice little hump on which long vehicles can now get stuck, which isn't what you'd want, either. Fixing that in turn means rebuilding an even more considerable section of the crossing street, with all that that entails...
