Jefferson County - East-West Gateway Coordinating Council

A Regional Overview All-Hazard Mitigation Plan 11
Analysis and Prioritization of Mitigation Actions
Jefferson County’s mitigation actions promote and/or support the development of local
hazard mitigation plans, projects and activities. Examples of actions include instituting
watershed plans, encouraging adoption of the most current codes and ordinances,
development of flood fighting plans, prioritizing flood buyout properties.
The following matrix provides an analysis and prioritization of the county’s hazard
mitigation goals, objectives and actions. The matrix distinguishes between the identified
hazards and the county’s mitigation actions. It is recommended that the County will place
an emphasis on cost-benefit analysis for further mitigation project prioritization purposes
when the budget analyses are conducted. The matrix also identifies those agencies
responsible for implementation along with the respective funding sources. It is
recommended that actions be coordinated, where applicable with Missouri’s mitigation
actions.
Criteria for prioritization are:
Historically, Jefferson County has been most affected by flooding hazards followed in
severity by tornado/thunderstorm, severe winter storm, heat wave, and drought. The risk
of earthquake, dam failure and wildfire must be addressed, even though the County has
not yet experienced these hazards.
Some actions may be high priorities, but will require a lengthy planning process. These
types of actions will be designated as a “high priority” with a future target date for
completion.
Certain hazards can impact incorporated areas more than the County as a whole. The
incorporated areas that could be specifically affected are identified as follows:
1= Arnold
2=Byrnes Mill
3=Cedar Hill Lakes
4=Crystal City
5=DeSoto
6=Festus
7=Herculaneum
8=Kimmswick
9=Pevely
10=Scotsdale
11= All communities
Jefferson County involvement is assumed for all of the items on the following Action
Matrix.
