David S. Ziegler Papers on the Tahoe Regional Planning Agency

Identifier: 2015-29

Scope and Contents

All of the materials in the David S. Ziegler Papers on the Tahoe Regional Planning Agency (TRPA) relate directly to the TRPA and were collected by Ziegler during his time served with the TRPA, 1981-1994, although there are a number of reports that predate Ziegler's time on the TRPA. A majority of the collection is comprised of reports and publications created both by and for the TRPA. One of the major areas represented is in regards to the water quality of Lake Tahoe. These reports represent a significant portion of the collection.

A small portion of the collection is dedicated to three separate court cases in which the TRPA was involved. This includes California League to Save Lake Tahoe vs. TRPA (1987), William Cody Kelly vs. TRPA (1980), and Tahoe-Sierra Preservation Council (TSPC) vs. TRPA (1997-2002). These cases document just three of the many court cases in which the TRPA was involved since it was founded in 1969.
