Lighting Regulations in Port Isabel, Texas: Preserving Maritime Heritage Through Thoughtful Illumination

Introduction: Port Isabel's Unique Character

Port Isabel stands as one of southern Texas's oldest communities, with a rich history dating back to 1519 when Spanish explorer Alonzo de Pineda first charted the area.
