John, I very much agree with Pete about reviewing Jeremy's essay on the routing as a concept of a journey of discovery of the property's assets. That journey-routing should floolw a certain logic as to how one would set about exploring an interesting property.
One question that comes to mind is the frequency of the elevation changes. Is it a very gradual and subtle rise and fall of the 25 ft elevation change that I imaging that area of the country typically flows; or does this property have a bit of quirk and atypical character with high frequency of hills and depressions, bowls and eskar like features. If it is a high frequency rolling terrain, you are lucky and I would urge you to concentrate on use of the contour as naturally as possible rather than artificially shape out fairway movement. That is an ideal though and probably not likely in that region. If it is more like the subtle long flow rises and falls, I would pay particular attention to techniques of manufactured terrain features and one place I would study the heck out of is Yeaman's Hall. If you have to shine up the land for golf strategy and feature creation, I really think that Raynor and Langford are two models that should be studied. Too many archies are falling into the typical large beast burial cemetaries to corridor the golf holes. If you have room, don't be afraid to leave those areas of hole separation un-dozed and shaped as much as possible.
I also assume that rainfall and drainage to take the water off efficiently is very problematic for Louisiana. Again, many of the old masters had some real savvy about moving water on the surface with cleaver drainage ways just outside of typical areas of play around the fairways. Does you soil perculate quickly or is it tight and resistent to fast infiltration. That question would have to be a real priority to answer before you can really shape out a general terrain-strategy concept.
Without a doubt, Jeff B and Tom D are the ones to really respond to this post. But, excuse my ramblings because this is the type of question that really keeps me interested here on the DG inorder to satisfy the hobby.-obsession with GCA. No doubt everyone on the panel here would love a topo map of your land to imagine their own creative routings...
