Drainage Identification, Analysis and Mapping System (DIAMS) is a computerized database that captures and stores relevant information associated with all aboveground and underground hydraulic structures belonging to the New Jersey Department of Transportation (NJDOT). DIAMS retrieves relevant performance and financial information so that NJDOT can remain compliant with Phase II of the Government Accounting Standards Board Statement 34, which is NJDOT’s sole means of reporting all financial transactions, namely the value of infrastructure drainage assets on an accrual accounting basis. DIAMS also retrieves all relevant environmental information to comply with the Clean Water Act and reporting requirements of the NJDEP.
