HomeServicesAs-Built Surveys › Lemont, IL

Lemont sits along the Des Plaines River valley and the Sanitary and Ship Canal in southwestern Cook County, with quarrying history, hilly terrain, and expanding residential subdivisions. Its varied topography makes verified final grades especially important at closeout. A final as-built survey documents where the completed improvements were built and at what elevation and compares them against the approved plans so the village can accept the work.
