About this map

Long Key and the southern Pinellas Peninsula define this mid-century coastal landscape, showing the rapid development of the Gulf beaches alongside established mainland neighborhoods. The barrier island is heavily subdivided, featuring the distinct layout of Don Ce-Sar Place and the community of Pass-a-Grille Beach, where the Sunshine Sch served local families. On the mainland, St Petersburg and Gulfport expand around Lake Maggiore and the shores of Boca Ciega Bay.

Significant infrastructure of the era is evident, most notably the Sunshine Skyway Toll Bridge stretching across the waters toward the south. Beyond the growing residential blocks, the map documents a complex network of keys and bayous, including the Pinellas National Wildlife Refuge at Tarpon Key. This survey preserves the geography of the shoreline before later decades of further dredging and artificial island creation changed the coastal profile.
