Short answers

Where does Avon flood?
Mainly the low avenues by the Shark River, especially 2nd and 3rd Avenues, and around Sylvan Lake.
Key East becomes Avon.
The area was once called Key East. In 1883 the Avon Inn went up at the foot of Sylvania Avenue, and the town that grew around it became Avon-by-the-Sea, named either for the inn or for Avon in England. It was incorporated from part of Neptune City on March 23, 1900, and has run under a Walsh Act commission since 1919.
It’s small and close-knit: about 1,900 people, a third of them over 65, in Victorian and shore homes between Sylvan Lake, known for its swans, and the Shark River inlet with its drawbridges. In 2000, 36.5% of residents claimed Irish ancestry, the third-highest share of any U.S. town.
It’s also one of the most flood-exposed towns on the Monmouth coast, and we write every Avon policy with that in mind.

An independent agency for a flood town.

When the Shark River comes up 3rd Avenue again, you call people who already know your house.
