A.D. Marble has completed 66 conditional assessment inspections (CAIs) for existing stormwater control measures (SCMs) throughout District 3-0. Certified condition assessment inspectors completed in-depth inspections of each SCM, and a Professional Engineer then completed QA/QC reviews. A.D. Marble used its unmanned aircraft (i.e., drone) capabilities to assist with the fieldwork by capturing aerial images of some SCMs and individual features, when possible. These capabilities were particularly useful for SCM overview images and areas that were difficult to adequately capture through on-the-ground images, due to areas of deep ponding and dense vegetation.
