Another resource that may be helpful is the Site Planning and Design Technical Manual (TM 5-803-14)that can be found on the US Army Corps of Engineers website. It discusses the design process, site analysis, and gives design guidelines. I don't recall the exact web address, but if you reach the Corps of Engineers website through a search engine, you can drill down through TECHINFO/Army Technical Manuals/ you should see it.<br>

If that doesn't supply enough detail, the Land Development Handbook - Planning, Engineering and Surveying by Dewberry & Davis may be helpful. It is published by McGraw-Hill. I believe their website is McGraw-Hill.com where you can view more detailed information of what is contained in the book.
