For this project, ABNA was the prime surveyor of record. ABNA’s Surveyors completed three of Forest Park’s major waterways: Round Lake, Jefferson Lake, and Bowl Lake & Seven Pools. Where the lake was over 3 feet deep, sonar technology was used to obtain a dual reading of the top silt and bottom of the pond. ABNA also prepared topographic surveys and land surveys, including the watersheds around the project site, and located over 90 manhole structures and performed a condition analysis, creating a geographical database. Survey data was collected in the field with GPS and robotic instrumentation.
