Hazard Identification and Risk Assessment A hazard identification and vulnerability analysis was completed for the Village of Blue Mounds using the same methodology in the base plan. The information to support the hazard identification and risk assessment for this Annex was collected through a Data Collection Guide, which was distributed to each participating municipality to complete. The first step in a hazard analysis is to identify which hazards the community is vulnerable to. Table 1 outlines the hazard identification for the Village of Blue Mounds based on the Data Collection Guide issued in The Data Collection Guide listed all of the hazards that could impact anywhere in Dane County. The purpose of this worksheet was to identify and rank the hazards and vulnerabilities specific to the jurisdiction. The Village s planning team members were asked to complete the matrix by ranking each category on a scale of 0 to 3 based on the experience and perspective of each planning team member. A ranking of 0 indicated no concern while a ranking of 3 indicated highest concern. This matrix appears as Table 1. This matrix reflects the significance of the hazards relative to one another. Dane County (Village of Blue Mounds) 1

2 This matrix reflects that the Village of Blue Mounds is most vulnerable to flood, winter storms, windstorms, and tornados. The Village has a medium vulnerability to extreme cold, drought, and lightning, and a lower vulnerability to dam failures, erosion, extreme heat, fog, hail storm, landslide, and wildfire. The vulnerability established here is a qualitative assumption based on the impacts, geographic extent, probability of future occurrence, and magnitude/severity. On the County level, these vulnerabilities were calculated with quantitative data as well. Dane County (Village of Blue Mounds) 2

4 Previous Hazard Events Through the Data Collection Guide, the Village of Blue Mounds noted specific historic hazard events to include in the community profile. These events have been incorporated into the appropriate hazard chapters in the base plan. These events had a particular impact on the community beyond the impacts and events recorded in the Dane County Hazard Mitigation. This is not a comprehensive summary of past incidents, as the hazard profiles collected in the main Mitigation include other events that may have historically impacted the jurisdiction. The events noted by this jurisdiction in the Data Collection Guide include: Winter Storm: February 6 and 7, 2008 The entire village was impacted by the winter storm that moved through the County in early February of Though no deaths, injuries or damages were reported, schools were closed and roads were delayed in opening. The Village was part of the Snow Emergency Declaration and received $2, in federal aid to assist with the costs of responding to the snow event. The data collection guide indicates the Village feels the event is likely to happen again. Asset Inventory Assets include the people, property, and critical facilities within the Village of Blue Mounds that are exposed to hazards in general. Inventories of property, essential infrastructure, and natural, cultural or historic resources help provide a comprehensive picture of the community and provide a method of assessing exposure to hazards by establishing the improved and total values, capacities and populations for these assets. It also forms the basis for estimating potential losses, where possible.

The previous inventory tables quantify what is exposed to the various hazards within the Village of Blue Mounds. Table 6 cross-references the hazards with the various tables where exposure or vulnerability specifics are found. The intent of Table 6 is to quantify, where possible, future impacts of each hazard on the jurisdiction. In many cases it is difficult to estimate potential losses, so the overall exposure of populations, structures, and critical facilities is referenced.

10 Tornado While it is difficult to estimate specific losses to a tornado due to the random nature of the event, a methodology was developed that was applied to each jurisdiction during the 2009 update. The table below estimates the percent area of the jurisdiction that could be impacted based on the average sized tornado (F2) in Dane County. High value exposure is based on 100% loss, medium 50% loss, and low is 25% loss to the property potentially impacted. The loss ratio, which is the ratio of the damaged building value to total exposed building value, is a measure of the impact to the jurisdiction as a whole. Communities with loss ratios 10% or more may have difficulty recovering from a disaster. Refer to the tornado hazard profile in the main mitigation plan for more details on this methodology.
