Larchmont Regional Stress Index
Larchmont is Westchester's second-lowest-stress Sound Shore village by passive physiological metrics. Long Island Sound proximity still generates negative ions here, just fewer than Rye's open coastline. Manor Park's 5,000 feet of shoreline does the heavy lifting.
The real stress driver is New Haven Line crowding, not the coastline. Larchmont sits closer to Grand Central, but trains fill up first at Rye and Mamaroneck. By the time a train reaches Larchmont, seats are already gone.

Larchmont Local Nuance
Larchmont Manor Park is the village's passive recovery anchor. Thirteen acres and more than 5,000 feet of Sound shoreline, striated rocks included. The Larchmont Manor Park Society has kept it open dawn to dusk since 1892.
Larchmont trades Rye's beach club system for a marina identity. Larchmont Harbor anchors the Larchmont Yacht Club, and Chatsworth Avenue anchors everything else. Chatsworth Avenue is walkable straight from the train platform.
Larchmont is an incorporated village inside the Town of Mamaroneck. It packs roughly 6,000 to 6,600 residents into 1.1 square miles. Median home values run past $1.6M, with owner-occupancy near 73%.
