Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
4.25 Severe flooding will cause extensive inundation and flooding of numerous roads and buildings resulting in a significant threat to property and life. Water will be 2 to 3 feet or more above ground level in some areas. Severe flooding will extend inland from the waterfront and shoreline flooding homes, businesses and isolating some neighborhoods. Numerous Homes are surrounded by up to 1 FT of water along Bishops Head Rd, Crocheron Rd and Lakesville-Crapo Rd.
3.75 Widespread flooding of vulnerable areas will result in an elevated threat of property damage to homes and businesses near the waterfront and shoreline. Water will be 1 to 2 feet above ground level in some areas resulting in a sufficient depth to close numerous roads and threaten homes and businesses. Water is up to the steps of the Kathy Noonan Center and the Parking Lot at the Marina on Fox Creek Rd is flooded.
3.25 Shallow flooding is expected in the most vulnerable locations near the waterfront and shoreline resulting in a low threat of property damage. Expect up to one foot of water above ground level in low lying, vulnerable areas. Multiple roadways begin to flood including Bishops Head Rd, Crocheron Rd and Lakesville-Crapo Rd.
