Washoe County has taken significant steps to update its flood hazard information, particularly focusing on the Swan Lake area, to help residents become more aware of their flood risks. This effort aligns with the Federal Emergency Management Agency (FEMA) requirements and aims to refresh the FEMA Flood Insurance Rate Maps (FIRM), which detail the 1 percent risk (100-year) flooding zones around Swan Lake.
The update is especially important as it replaces previous maps based on outdated studies and mapping technologies. Changes to weather patterns and improvements in analysis tools over time necessitated this new approach, as noted by county officials. The last update to FEMA’s maps occurred back in 2009, indicating how long residents have relied on information no longer accurate or reflective of current circumstances.
Using new digital mapping techniques, Washoe County has been able to generate much clearer topographical information on areas susceptible to flooding. The remapping project highlights how flood risks evolve, whether due to natural events, environmental changes, or improved analytical approaches over time.
Notably, approximately 95 additional residential properties are now included within FEMA’s current 1 percent (100-year) floodplain boundary for Swan Lake, which elevates the total of affected residential properties to around 192. This adjustment also includes about 14 federal, Washoe County, and commercial properties recently identified as being within the floodplain boundary.
Dwayne Smith, Washoe County's engineer, stressed the importance of residents assessing their flood risk. He explained, “Residents who don’t know their flood risk might be inclined to skip obtaining the proper insurance, and this could have detrimental effects on their homes if and when a flood happens. Just as those who live in the wildland-urban interface are more likely to experience wildfires, and those living in seismically active zones are more likely to experience earthquakes, those living in floodplains have a greater risk of experiencing flooding, and they need to be aware of their risk.”
This statement underlines the potential dangers faced by residents who remain unaware of their surroundings and the risks posed by natural disaster events like flooding. To alleviate these concerns, Washoe County is committed to effectively communicating the updated flood risk information to residents and helping them make informed decisions.
Washoe County has proactively engaged with those affected by the changes. A letter has already been sent to residents impacted by the updated floodplain to inform them of these changes and their potential consequences. To facilitate community engagement, the county is organizing a meeting scheduled for January 29, 2025. At this meeting, residents can ask questions and learn more about flood risks from county officials and flood management experts. This event is part of Washoe County's broader strategy to keep residents informed through active communication and local outreach.
Notably, the flood risks have increased due to various factors, and as highlighted by Washoe County, "New digital mapping techniques provide clearer information on where flood water may encroach or where flood hazards have increased.” This assertion emphasizes the significance of utilizing advanced tools and technologies for effective flood management.
With this updated information, residents are encouraged to explore their flood insurance options proactively. Considering the changes brought about by the remapping efforts and the potential additional properties joining the floodplain, it becomes evident how important it is for homeowners to review their insurance coverage and be prepared for any emergencies.
Washoe County fully understands the concerns associated with these updates and the responsibilities they carry. Resources are available to assist residents and commercial property owners with any inquiries related to the floodplain information or insurance questions.
