Hawaii DOT's Comprehensive Stormwater Asset Management System: A Critical Tool to Meet NPDES Permitting Goals

With the implementation of Phase I and Phase II NPDES permits, many state DOT's have MS4 permits that require the mapping of the DOT-owned storm drain network as well as implementation of best management practices (BMPs) to fulfill six minimum control measures including public education and outreach, public participation and involvement, illicit discharge detection and elimination, construction site stormwater runoff control, post construction stormwater management in new development and redevelopment, and pollution prevention/good housekeeping measures. As partial fulfillment of the Island of Oahu's MS4 NPDES Permit (No. HI S000001), the State of Hawaii Department of Transportation, Highways Division (DOT-Hwys) has developed an Asset Management System (AMS) to provide program staff with tools for the efficient and effective management of information generated by the components of the Statewide Storm Water Management Program (SSWMP). The AMS is capable of housing and organizing vast amounts of data, providing the means for program staff to analyze this data through computerized processes and solutions. AMS will provide the following support to the Oahu SSWMP. This paper will document the challenges and successes that HDOT has had in the development and implementation of a comprehensive, web based asset management, system.
