In addition to furnishing topographic and hydrographic surveys, McKim & Creed mapped the majority of this project site using aerial photography and photogrammetry. The survey produced a 1-foot contour map showing all visible planimetrics, including all structures, paved roads, soil or sand roads, trails, docks and bulkheads. Ground surveys supplemented the efforts in order to acquire topography on any obscured areas, hard surface road elevations, docks and piers, and the sub-aqueous areas between elevation 0′ and -4′ NAVD88.
