Flood Emergency Action Plans

Content

These Flood and Severe Storm event Emergency Action Plans have been developed and public versions are available:

山谷水为圣克拉拉县提供洪水管理服务。在严重风暴事件和洪水普通小溪中的高流量期间,谷水可以实现紧急行动以保护生活,财产和环境。为此,山谷水与合作伙伴机构,土地所有者和其他利益相关者密切合作,以确保在紧急事件中进行协调的方法。

To improve the response to potential or actual flooding events, Emergency Action Plans have been developed that provide guidance on how Valley Water will prepare and respond to severe storm and high flow events. The plans describe 5 basic steps taken in response to storms and flood events.

  1. Event Detection
  2. Condition Level Determination
  3. 通知和通信
  4. 行动和责任
  5. Termination and Follow-up

A key component of these plans is to create an easy-to-understand and easy-to-communicate classification system for setting a condition level based on flood risk and flood severity. Before and during events the level of risk for flooding uses the color-coded system shown below:

Flood risk color-coded table

With the risk of flooding classified, the urgency of an event can be communicated and actions planned. However for actions to be most appropriate to the event, it is important to also understand and communicate how severe the event may be and what areas may be affected.

Valley Water and the National Weather Service both provide this type of classification. Below are the flood severity descriptions used by both agencies:

With an event's risk and severity established, the responsible agencies can best coordinate to provide a comprehensive response specific to the event.
