In today’s business world, using reliable information is crucial when making decisions and understanding how systems work. Virtually all data have a spatial component and our GIS team can help turn your raw data into tangible information that is easily accessible. By way of GPS, conventional surveying, and subsurface utility locations, our team can provide GIS utility or environmental mapping, to collect this raw data, helping you manage your assets.
We have recently developed a standardized GIS stormwater geodatabase for Collier County, populated with stormwater facilities constructed in conjunction with County roadway projects. The geodatabase was developed to fit standardized criteria already in place being used internally by Collier County staff and to help meet NPDES requirements for the County. Locations of stormwater facilities are taken from hardcopy and electronic documents, and assembled into a GIS geodatabase. Mapping includes over 770,000 LF of piped conveyances, over 4,900 inlets and junction boxes, over 200 individual water control discharge structures, as well as associated swales, ponds, and detention areas. Data gaps were filled in by our survey teams using GPS data collection methods, where plan sets were not available.
Information can then be extracted from the geodatabase in report or spreadsheet format and utilized to meet a variety of needs including operations and maintenance, hazardous spill response, and facilities management, in addition to NPDES reporting. Various documents are linked to the individually mapped features, like photographs, field notes, and PDF construction plan sets, making the geodatabase a central location for managing the stormwater infrastructure.
The geodatabase data acquisition model developed by Johnson Engineering can be readily adapted to other municipalities or airport FAA GIS requirements and can handle multiple data types in addition to stormwater, such as potable water, raw water, irrigation supply, gravity sewer, force mains, and gas mains.
