An abundance of critical infrastructure—public and private—resides along the Detroit River and Great Lakes. These include power plants, drinking water intakes, and municipal sewage systems as well as privately owned industrial sites and marine terminals. Shoreline failures can threaten occupied structures, expose underground utilities, wash out pavements, and cause sinkholes and slope failures. Under this ordinance, every five years, property owners are required to submit both a seawall and a geotechnical report and must give notice within 48 hours if there is a shoreline breach, flooding, structural failure, or environmental contamination. These reports are prepared by licensed professional civil engineers who will provide an analysis of the structural integrity of the seawall and a maintenance and repair schedule for any issues identified in the report.
Shoreline protection has never been more important, and investments made now – both private and public -- will protect valuable recreational, commercial and industrial assets into the future. Existing shoreline systems do not have an unlimited service life and issues such as changing water levels, river scour, adjacent loadings not considered at the time of design and construction, as well as normal aging and deterioration, can lead to seawall distress and ultimately failure.
NTH’s knowledgeable civil engineers have extensive design and rehabilitation experience with seawall and shoreline protection systems on the Great Lakes and Detroit River with ongoing inspection diver and seawall contractor relationships that can assist with evaluation of current conditions and rehabilitation of existing structures. NTH also owns a Remotely Operated Vehicle (ROV) that allows our highly trained staff to inspect and assess the condition of your underwater assets – quickly, cost effectively and safely.
