The New York State Office of Parks, Recreation and Historic Preservation (OPRHP) has replaced deteriorating railings and asphalt pavements at two locations within Niagara Falls State Park, the Three Sisters Island group above the Horseshoe Falls on the south side of Goat Island and Luna Island that separates the Bridal Veil Falls from the American Falls on the north side of Goat Island. The work included installing new railings, pavements and landscape areas with the goal of returning the Park to the original vision of the Park designer, Frederic Law Olmsted.

MMCE provided geotechnical engineering services for the project to Erdman Anthony and Trowbridge and Wolf. The geotechnical work began with a review of existing information including 1944 construction plans and boring logs for the Three Sisters Bridge project as well as work by the US Army Corps of Engineers on Luna Island and the American Falls when the American Falls was dried up in the late 1960’s. MMCE engaged Earth Dimensions, Inc. (EDI) to drill test borings and retrieve rock core samples at Three Sisters and Luna Island and prepared geotechnical recommendations for design and construction of the new railing foundations, pavement support and subsurface drainage.
