Perdido Beach is a small town on the northern shore of Perdido Bay, sitting between the mouths of Soldier Creek to the west and Palmetto Creek to the east. It only incorporated in 2009, which makes it one of the youngest municipalities in Baldwin County by charter. Census data puts the median year built at 1985 across about 410 housing units, with five pre-1939 structures — a small, mostly-recent residential stock spread along the bay shoreline rather than clustered in a downtown core.
Water service splits between Orange Beach Water Authority reach and private wells, with the bayfront orientation creating the local install nuance. Bay-edge wells require chloride monitoring as an ongoing baseline — Perdido Bay is brackish, and freshwater drawdown can pull saltwater into shallow wells over years. The chloride concern is the same one that defines the Bayou La Batre and Lillian install conversations.
On the OBWA-served side, the install pattern mirrors Orange Beach proper: hardness as the residential driver, RO at the kitchen tap as the universal coastal preference for drinking water. The Perdido Beach-specific overlay is the saltwater-intrusion vigilance, which makes baseline chloride testing the appropriate first step before specifying equipment for any private-well address within sight of the bay. Soldier Creek and Palmetto Creek both discharge to the bay close to the town's footprint, which adds creek-watershed considerations to well-siting decisions for properties farther inland.
Town-charter age is the other practical lens. Perdido Beach voted itself into incorporation in 2009 — making it the youngest charter in Baldwin County — so the town inherited no zoning lineage of its own. Lot boundaries, well-setback rules, and dock-permitting authority traced through the county before that date and shifted to mixed municipal-county jurisdiction after. The bay-edge orientation also means the town faces the Florida line directly across the water from the Lillian Bridge approach, with Pleasure Island narrative anchors (Soldier Creek, Palmetto Creek, the bay itself) doubling as both geographic markers and zoning sub-districts. Census records show only 555 residents at the 2020 count — by far the smallest population on the city list — and a residential pattern dominated by single-family bay-shore parcels rather than the condo density that defines Orange Beach or Gulf Shores. Property-by-property variation is the rule, not the exception.
