commercial properties [tooltip name="flood-localitycommercial" content="" /]

In addition to damage on properties, flooding can also cut off access to utilities, emergency services, transportation, and may impact the overall economic well-being of an area. Overall, Ann Arbor has a moderate risk of flooding over the next 30 years, which means flooding is likely to impact day-to-day life within the community. This is based on the level of risk the properties face rather than the proportion of properties with risk.

infrastructure facilities [tooltip name="flood-localityinfrastructure" content="" /]

homes [tooltip name="flood-localityresidential" content="" /]

miles of roads [tooltip name="flood-localityroads" content="" /]

There are 2,275 properties in [tooltip name="general-locationtype" content="Ann Arbor" /] that have greater than a 26% chance of being severely affected by flooding over the next 30 years. This represents 13% of all properties in Ann Arbor.

social facilities [tooltip name="flood-localitysocial" content="" /]

Ann Arbor Flood Risk [tooltip name="flood-communityoverall" content="" /]

Communities that adapt to higher risks can limit damage and lower flood insurance costs. Ann Arbor is already investing in flood risk reduction projects, but more may be needed. <a href="https://riskfactor.com/solutions/flood">Learn more about solutions.</a>

Known adaptation measures [tooltip name="flood-adaptationcount" content="" /]

Properties protected by adaptation [tooltip name="flood-adaptationprotected" content="" /]

Lowering flood risk starts with higher standards. Some places plan to a higher standard (a &#8220;500 year&#8221; standard) that lowers the number of properties at severe risk. Protecting homes to this level would reduce the risk to the 2,275 severely affected properties.

text-center

Note: 966 properties in this area are protected by an <a href="https://help.riskfactor.com/hc/en-us/articles/360051062333-Adaptation-types">adaptation</a>. While the above projections take into account this reduction, risks may substantially increase in the event of failure.

Deeper floods from major events, like hurricanes, are less likely to occur, but affect more properties than more shallow flood events, like heavy rains. As Ann Arbor feels the effects of a changing environment, however, events of all kinds will affect more properties within the community.
If a low-likelihood storm resulting in severe flooding (a [tooltip name="flood-eventdefinition" content="1-in-100 year flood event" /]), occurred today, it could affect 2,204 properties in Ann Arbor. This type of event has a 26% chance of occurring at least once over the life of a 30 year mortgage. 30 years from now, an event of this same likelihood would affect 2,336 properties due to a changing environment.

Depth of flooding (ft.) [tooltip name="flood-historiclocalitycount" content="" /]

Properties impacted in Ann Arbor[tooltip name="flood-historicoverall" content="" /]

A changing environment means higher seas, new weather patterns, and stronger storms. As the atmosphere warms, there is more evaporation and more water available when it rains. A warmer atmosphere also means warmer oceans, which can intensify flooding from hurricanes and offshore storms. Sea level rise also increases coastal flood risks, as higher seas mean there’s more water available when high tides and coastal storms cause flooding.

Individuals, mayors, governors, and Congress can work together to build protections before flooding, build back stronger after flooding, and create plans that future-proof communities.

In addition to the flooding risk described above, Ann Arbor has minor risk from wildfires, minimal risk from severe winds, and moderate risk from heat. To learn more details about Ann Arbor’s risk and solutions visit this area’s Risk Factor pages below.

Flood-AAL

The Average Annual Loss is the percent of the structure value that is impacted based on the full risk profile (a depth times likelihood integration). You can multiply it by the property value of a given structure to get a proxy for the $ value of damage from the flood risk profile in any given year.

Fire-WUI-5

WUI, or Wildlife Urban Interface, is a special designation given to residential areas by the USDA Forest Service. Homes in a designated WUI are required to meet certain compliance standards for wildfire prevention.

Fire-WUI

Fire-DamageEstimate

This denotes if the property is likely to sustain damage and associated repair costs based on its building characteristics and vulnerability to nearby wildfires in the current year. You can edit building characteristics and see damage scenarios on the fire damages page.

Fire-Maps-flamesTitle

Likelihood of wildfire flames to reach this property.

Heat-FeelsLikeTemp

&#8220;Feels like&#8221; temperature is another word for &#8220;heat index&#8221; which is the result of combining air temperature with humidity to describe how heat feels due to the moisture content in the air. This is an important measure of temperature because this felt experience of heat is an important indicator of our bodies&#8217; ability to cool itself and stay safe on hot days.

Heat-HotDayDefined

A hot day is defined by using the 98th percentile &#8220;feels like&#8221; temperature in a specified area, or in other words the lowest daily high temperature on the hottest 7 days in a given year.

Flood-RecreatedModel

Risk Factor&#8217;s historic data is based on recreated models of flood events and not on recorded levels of flooding. While there may be some slight discrepancies from observed events this methodology meets statistical standards for accuracy and has been validated accordingly. <a href="https://help.riskfactor.com/hc/en-us/articles/360050783973-How-were-historic-floods-recreated-for-Flood-Factor-" rel="noopener" target="_blank">Learn more</a>.

Flood-SliderExplained

Homes with severe flood risk or with 30 year flood risk that is the same as current flood risk may not see any change on the flood projections map.

Fire-EmberCast

Wildfires produce large pieces of burning debris known as embers, which can be carried several miles from an active wildfire by wind and smoke. When flying embers land on a burnable material such as dried fuels or possibly even in a building, it causes fire to spread through a process known as spotting. Ember risk should be considered by owners of at-risk properties and precautionary measures should be taken to further reduce susceptibility.

Fire-MaxFlameLength

The maximum estimated height, or length, of flames at this location based on all fire scenarios where fire reached the largest building on this property.

Fire-AverageFlameLength

The average estimated height, or length, of flames at this location based on all fire scenarios where fire reached the largest building on this property.

Fire-Maps-EmberCast

Fire-SliderExplainedNonresidential

Buildings with 30 year wildfire risk that is the same as current wildfire risk may not see any change on the wildfire risk probability map.

Fire-propertyDetails-defensibleSpace5ft

If there is no vegetation or flammable materials within 5 ft of the building, and the proportion of vegetation or flammable materials within 50 ft of the building is less than 15% then it is low risk.

Flood-DamageEstimate

The estimated cost of all potential flood damages, based on this property&#8217;s flood projections. <a href="https://help.floodfactor.com/hc/en-us/articles/1500002966002-How-are-flood-damage-estimates-and-Flood-Factor-scores-related-">Learn more.</a>

The estimated change in energy use is based on the change in days required cooling.

Overview-OverallPropertyDetails

Property details can be adjusted within the Pro experience by going to any of the &#8220;Damages&#8221; pages. Adjusting property details will not change the property&#8217;s risk from environmental impacts, as that is based on the property&#8217;s location, but it could impact the damage consequences associated with that risk.

Fire-CompleteDestruction

This shows the likelihood of the structure being completely destroyed if wildfire were to reach it. This takes into account the height of the flame length and the property and building characteristics such as the defensible space and fire proofing upgrades.

Flood-FEMAZone

Federal Emergency Management Agency (FEMA) flood maps are primarily used to determine flood insurance requirements and do not determine a property&#8217;s Flood Factor.

Flood-ConsequencesAnnualizedDamages

Annualized damages are calculated by multiplying the likelihood of a flooding event to happen in a given year by the damage it would cause. As a changing environment makes floods more common and severe, the annual damage forecasted each year goes up.

Flood-ConsequencesbyLikelihood

Flood depth can vary depending on how likely a flood event is to occur. Events that are less likely have the capability to bring higher flood depths than a more likely event.

Flood-ConsequencesbyDepth

Flood depth can vary depending on the severity of the event. This can also impact the potential damages incurred by a property in a flood.

overallDetails-squareFootagePrice
