GPS Surveying & Mapping

The annual inspection and maintenance of stormwater inlets requires accurate record keeping. SCS completes this task by using GPS based mapping systems to inventory the inlets and assign unique identifiers to each structure. A detailed inspection is completed of each inlet and minor cleaning is completed as part of the normal annual inspection. If repairs and/or higher level cleaning is required, the work is completed based on a pre-established menu of services.

Stormwater outfalls from MS4s are located using GPS systems and inspected for scouring at the discharge point. The outfalls are also documented photographically to establish a baseline for future inspections and to judge the degree by which conditions change over time.

The stormwater information that has been gathered by means of the GPS systems is downloaded into industry standard GIS mapping systems. The inspection results, photographs and other information are linked to the map.
