About West

Side

West Side, located between Deer Park Avenue and Commack Road, is a suburban and residential Deer Park neighborhood with a rail-adjacent edge and a patchwork of mid-century capes. The neighborhood’s character concentrates around Deer Park Avenue near the Deer Park LIRR station, where small storefronts, takeout counters, and service shops set a steady, everyday rhythm. Side streets read as quiet and practical, with tidy lawns and driveways framing compact lots. The Long Island Rail Road corridor and nearby arterials shape the soundscape and commuting patterns. Tanger Outlets Deer Park adds a modern retail district just beyond the residential grid. Belmont Lake State Park brings broad trails and water views into the local routine.
