DC Zoning

DC Zoning Office system shreds paper-based processing

For years, the D.C. Office of Zoning, which provides administrative and technical assistance to the District’s Zoning Commission and Board of Zoning Adjustment, required applicants for zoning approvals to appear in person and submit 20 copies of all supporting documents. The tedious paper-based workflow caused difficulties in retrieving information, significant storage costs and laborious coordination with other agencies. Responding to what had become an intolerable system, the DCOZ IT team developed a Web-based system that provides for electronic case filing, processing, management of zoning cases and electronic distribution of final decisions.

The Interactive Zoning Information System (IZIS) was developed using object-oriented software development techniques to enhance re-usability, maintainability and scalability. Sun J2EE blueprint and Jakarta STRUTS were used to build the core of the system, which is supported by a Microsoft SQL Server 2008 database. Industry standard design patterns Singleton and MVC form the basis of IZIS components while Java, Java Server Pages, Servlets and JavaScript were used to develop interfaces. IZIS is also integrated with iFileNET and the Office of Zoning’s ESRI-based GIS system to validate geographic information.

Extensive training was conducted to ensure a successful launch of the system and smooth ongoing operations. Today, the IZIS enables the public to conduct online searches and instantly retrieve case information going back to 1970.
