occurred late this afternoon in response to an enormous storm cell that passed over the valley dropping about a half-inch of rain in less than an hour on hard-baked soils. Overland flow and sheet-flooding began immediately and ditches ran at full capacity along roadways for more than an hour. The National Weather Service did post both flash flood and severe thunderstorm warnings for the region and the last time an event this intense occurred was around 2010.
Peak runoff down the lane occurs as the storm cell moves eastward, with both roadside ditches running at full capacity. But a rainbow appeared and no personal property was damaged.
The low swale on the east side of my property took some runoff and sediment from small breaches in the berm along the roadside ditch.
UPDATE: The morning after in the mud bowl as the Town’s grader gets to work. There’s a lot of ditch maintenance that needs to happen beyond just clearing debris from the road surfaces.
