This technical note and its attachments are issued in response to the request made by the States at the last Watershed Planning Meetings held October 25-26 and December 19-20, 1966, for data related to urban flood damages. The following items are attached for use by the Economist: 3 1. A folder of generalized urban damage data for use in preparing preliminary investigation reports and watershed work plans, This supplements the urban damage data issued at the Northeast Watershed. Planning Party Economists Workshop held at Ocean City, Maryland, in July 17-21, 1961, and the Stanford Research Institute data recently issued with TSC Advisory 175-7 (UD) dated August 29, 1567. The use of generalized data requires a determination that the data are applicable, and therefore, does not eliminate the need for personal interviews of flood-plain occupiers.
