Low ground near the river behaves differently from the hills above the Green. When the Whippany runs high for a day or two after a big storm, the soil around nearby foundations stays saturated and groundwater can push in at the joint where the wall meets the slab. Owners often notice the pattern: the basement stays dry through an ordinary shower, then takes on water a day after a tropical system passes. That delay is a strong hint that the problem is a rising water table rather than a gutter, and it changes which repair makes sense.
Morristown's own flood rules matter on these blocks. The town's Flood Damage Prevention article requires a development permit before construction in a special flood hazard area, and new or substantially improved homes must have the lowest floor, including the basement, at least one foot above base flood elevation. Routine waterproofing inside an existing basement is usually a different matter from new construction, but any work that adds living space, excavates, or changes grading near the river can raise questions. A contractor working here should check the flood map for your lot before quoting, and you can confirm requirements with the town.
For homes on the higher streets of the ward, away from the river, the usual culprits are short downspouts, driveways that pitch toward the house, and older block or stone walls with no footing drain. Closer to the water, interior perimeter drains with a sump, a battery backup, and a high water alarm are common, since storms that raise the river also knock out power. A sump only helps if its discharge leaves the property in a sensible direction, so ask where the line will end before work starts. Flood insurance is a separate question worth raising with your agent.

Questions from Second Ward homeowners
My Second Ward basement only floods after the big storms. Why?
When the Whippany River stays high, the ground around nearby houses stays saturated and groundwater can rise into the basement through the floor joint. That is different from a gutter leak, which shows up during the rain itself. An interior drain and a reliable sump are the usual answer for groundwater.
Is my house in the Whippany River flood zone?
Check the FEMA flood map for your address, or ask the town. Parts of the Second Ward near the river are mapped as high risk. A good contractor will look this up before recommending anything and will tell you what a drain system can and cannot handle in a true river flood.
