From 1910, then as prineipal assistant engineer, he supervised all improvements of the District, including these condueted at Savannah Harbour and the Inside Waterway. This also included construction of bank-protections, stone jetties, wharves, and hydraulic dredges these works were summarized in special reports.

In some cases, mechanical dredging of the soft material can be a more advantageous solution since the shear strength of the relocated clay material will start from its remoulded/residual shear strength, which is higher than the shear strength of hydraulically dredged and placed slurry.
