I am using crushed local stone for my driveway and would like to get the point for high albedo materials?

Bill,
Depending on the green building program you are trying to qualify for, crushed stone may not be eligible for a high-albedo materials credit. For more information, see the discussion of a similar question that was posted a while ago:

Thanks Martin. Oh well, I will get the points for impervious material!
