arc ways to protect creek banks in a sensitive manner. I've attached some photographs of creek
repair projects that leave the creeks looking natural and more stable. The measures are proven and
are being used throughout the United States. They can work in San Luis Obispo too.

MEMORANDUM
October 2, 1997
TO: City Council
FROM: Mayor Allen Settle
SUBJECT: Urgency Item: Protecting the Water Reclamation Plant from Storm
Drainage
Due to the severe erosion to San Luis Obispo Creek in the vicinity of the Water
Reclamation Plant during the storms of 1994-95, there is a high likelihood that the Water
Reclamation Plant itself will be damaged by the winter rains, unless a contingency plan to
protect the plant is developed immediately.
Because of this, I have placed this item on the City Council agenda for October 7'so that
the matter can be discussed by the Council and staff so that the Council can provide
direction and the staff take actions to the end that potential plant damage is prevented or
minimized.
This is in accordance with the procedures set forth in Council Policy and Procedures,
Section 1.2.1.
