Bathymetric and Specialty Surveys

In Euclid, Ohio in Cuyahoga County, city officials were working on a long-range plan that included improvements to 2300 feet of Lake Erie shoreline. To help them plan, Lewandowski Engineers performed shallow water and deep water bathymetric surveys of the shoreline extending 700' into the lake as well as wade-in and near-shore upland topographic survey.

We documented drone photographs at 100' intervals over 2.5 miles and used a multi-beam echo sounder mounted on our 28' Baha Cruiser. Our 12-foot skiff was used for nearer shore work.

We have also done bathymetric surveys for the Toledo Metroparks and, shown below, for the Toledo Zoo.

With Bubbles the hippo safely in her pen, we were able to do a survey of the bottom shape of the hippo pool at the Toledo Zoo.

Another specialty is 3D surveys. These data-dense surveys map as-built conditions, virtual job sites, and more. We have used them to survey otherwise inaccessible river banks, bridge superstructure, building interiors, and streetscapes.
