The Internet provides new opportunities to show data in a way the public can easily access and use. GIS is interactive and can be simplified for general users and still convey meaningful information.
Project Examples
Who's in Charge? Mapping a Puzzle of Stormwater Jurisdictions
Client - NC Division of Water Quality

The question, “Who is in charge?” has a multitude of answers when stormwater is the subject. Stormwater permitting responsibility across North Carolina may be local, state, shared by multiple entities, or not even required based on Phase II stormwater legislation and rules. CGIA collaborated with the DWQ to develop the Stormwater Permit on-line mapping tool. For any location of interest across the state, a user may view the custom reference layer and see a table describing what program is in play, on what basis, and which public agency or agencies to contact.
DrinkingWater_mapviewer_table200911_thumb.png Is My Source of Drinking Water Susceptible to Contamination?
Client – NC Source Water Assessment Program

CGIA created and hosts an on-line map viewer that displays program data on drinking water assessment areas and their associated susceptibility ratings. Susceptibility ratings are a measure of potential contaminant risk and are classified as lower, moderate or higher for both surface and ground water sources. The ratings, displayed on a map and in a table, indicate whether a drinking water source is near a potential source of contamination.
