Standard messages to be used on the public address systems are given in Section IX of this plan. Dissemination should be made by as many different means as possible, but care should be taken to insure that warnings from different sources are similar in content. The warning message should clearly communicate the danger and recommend specific protective actions. Flood warnings for Ralston Creek and its tributaries can be issued by the broadcast media and loud speaker equipped vehicles. Confirmation of the initial warning is desirable whenever possible.
People tend to seek confirmation before reacting to a warning .
Response of the Public to the Warning If the desired response of the people in the flood hazard area to a warning is not obtained, the whole warning plan will have failed. Cultivation of the desired response must begin well in advance of any flood threat by heightening the public awareness of the flood hazard. The local governments will put a notice of the flood hazard in appropriate publications each spring before the flood season. Media coverage of the flood hazard, including the annual practice of the warning plan, will be sought.
