proper way of labeling batter behind retaining wall
say you have a retaining wall where the back face will be battered 1h to 30v.  would you write this as 1:30 or 30:1?
thanks  
i just put the dimensions instead of this notation.  but i believe the correct way to say it on your situation is 1:30.   
never, but never question engineer's judgement
1:30 or 3/8:12 (approx the same)
1h:30v

               !
               !
               !30
               !

sorry - didn't post right, but i think you get the idea...

as a prisoner of my own experience, geotechs - because of slopes always use h:v - so it would be 1:30. structural types like to use v:h so a structural designer (and even highway designers of structures) would use 30:1.  for myself, based on how i was mentored at the beginning of my career, i always put in the h and v with the numbers (1h:30v) so that whether one is using the argot of a geotech or structural-type - or a lay person - it will be understood.  limit confusion by proper and sufficient detailing.
i agree with bigh to always just put in the h and v. in my experience it is usually h:v, however when i did a project that happened to be in metric units it was v:h. also a graphical indication of the slope is acceptable.
good post bigh.
because drawings are used to provide construction documentation, my office has always shown the batter line, and shown the triangle next to it to display the slope, as per mike's post.
it would be hard to confuse a 1:30 with a 30:1. although batters are typically expressed in run per 12 units in rise to avoid confusion.
