Hazard Identification and Risk Assessment A hazard identification and vulnerability analysis was completed for the Town of Montrose 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 Town of Montrose based on the Data Collection Guide issued in 2008. 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. Town of Montrose 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 Dane County (Town of Montrose) 1
appears as Table 1. This matrix reflects the significance of the hazards relative to one another. This matrix reflects that the Town of Montrose is most vulnerable to extreme cold, tornado, windstorms, and winter storms. Hail, drought, extreme heat, and fog, and are of medium vulnerability. The Town of Montrose has a lower vulnerability to lightning and wildfires. The vulnerability established here is a qualitative assumption based on the impacts, geographic extent, probability of future occurrence, and magnitude/severity. Dane County (Town of Montrose) 2

Previous Hazard Events Through the Data Collection Guide, the Town of Montrose 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 Plan. This is not a comprehensive summary of past incidents, as the hazard profiles collected in the main Mitigation Plan include other events that may have historically impacted the jurisdiction. The events noted by this jurisdiction in the Data Collection Guide include: February 5-6 2008: Winter Storm Record snowfall affected the entire Town of Montrose during early February of 2008. There were no reports of injuries, deaths, property, crop or infrastructure damage, but impacts on business and the economy were unavailable. The snow resulted in delays and closures along roadways, and in schools and businesses. The Town of Montrose received FEMA funds in the amount of $4,181 for disaster relief. The Town of Montrose planning members feel such an event is very likely to occur again. July 3-7, 2008: Flooding Flooding affected the Town of Montrose. The event occurred at Schaller & Remy Roads. There were no deaths or injuries reported, but there was reported damage to property as a loss of 20 tons of shoulder aggregate material. Crop damage was reported by farmers. No business or other impacts occurred. The Town of Montrose received FEMA funds in the amount of $1,389 to help recover from the hazard. The Town of Montrose planning members feel such an event is very likely to occur again. Asset Inventory Assets include the people, property, and critical facilities within the Town of Montrose 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.

Other Assets Other assets help define a community beyond the current composition of the Town of Montrose. These assets may provide economic benefit to the community, in addition to preserving the heritage and diversity of the community and may include natural, cultural and historic assets or economic assets such as major employers. It may also include more specific detail on critical facilities. The Town of Montrose has identified these other assets in Table 5. Hazard specific vulnerabilities are noted, where known.

The previous inventory tables quantify what is exposed to the various hazards within the Town of Montrose 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.

These assets are collected in Table 7. Refer to the flood profile in the mitigation plan for a description of the methodology used to identify potentially flood-prone properties. Table 8 summarizes properties located in the floodway, typically the area of the floodplain where velocities are highest and flood depths the greatest, and thus could be considered a priority for mitigation. The locations of properties within the floodplain are shown in Figure 1, in addition to flood hazard areas and planned land use.

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.
