I would like to support Acorn's point about documentation. Like many here, I started html coding sites. I was in the marketing and advertising business in the, well let's just say, not this century. Time and again I saw websites disintegrate when the management inevitably changed hands. I've seen websites held hostage by their creators. I cannot emphasize enough Acorn's point about documentation and I would go even further than just the technical and design documentation. I would include all administrative and financial (as in hosting site) documentation and that it always be available to the business owner of the site. IMHO
