If your an Engineer looking for a couple good references on site plans, here are a couple books I have found helpful:
1 - Land Development Handbook (Planning, Engineering, and Surveying) by McGraw Hill
2 - Land Development for Civil Engineers by Dion
3 - Civil Engineering Reference Manual, of course
There seems to be very little information out there "instructing" engineers how to develop "good" grading plans. Quality grading and storm drain design may take more time, hence cost more, at the outset, but can save clients hundreds of thousands of dollars...
Long answer, not sure if I asked your question as it was rather vague. Possibly I can be of better help if you are more specific.
