Thanks to Nigel Hetherington's post to EEF, to point out that the Kings Valley Masterplan is online, on the Theban Mapping Project's webbsite: "In the spring of 2004, the Supreme Council of Antiquities (SCA) requested that the Theban Mapping Project (TMP) prepare a masterplan for the future management of the Valley. This project was generously supported by the World Monuments Fund (WMF), and the American Research Center in Egypt (ARCE), and several private donors. What follows is the main text of that management plan".
The full masterplan is available, in pdf format, from the above page - it is broken down into a set of chapters, so each one needs to be opened separately. Although the masterplan is mentioned in the August 2006 Progress Report, it does not provide a link to the above page.
