floodplain information following their acceptance and approval by the CWCB Hydrology
Advisory Committee and the Board. The CWCB staff and the Hydrology Advisory Committee
feel that this approach is appropriate for calculating flows for approximate floodplain delineations,

for the development of the Guidelines. The "Proposed Motion" is as follows:

ProDosed Motion

The Board, having reviewed the Board memorandum summarizing a proposal for
the development of the "Guidelines for Determining Flood Peaks for Approximate IOO-Year
Floodplains", now moves as follows: to approve as suitable for Board approval and designation
of lOO-year floodplain information the regional regression methodology proposal in the attached
Work Plan, to authorize the Board staff and the CWCB Hydrology Advisory Committee to
proceed with the preparation of the Guidelines and to approve the proposed order of study for
