Success Story

Assessor Modernization Project (AMP)

The Los Angeles County Assessor's current information technology environment includes over 120 aging mainframe applications – many of which were originally implemented between 1965 and 1978. After conducting an extensive evaluation of commercial off-the-shelf products and consulting with Sierra Systems, The Gartner Group and the Los Angeles County Chief Information Office, Oracle was selected to develop the first phase of a five-phase agile development project to replace the Assessor’s outdated systems.

Phase I established the overall enterprise architecture and plan for future phases and outlined the foundational system components including the creation and population of a new Assessment Roll system; rewrite of the "Assessor Portal" interface for both personal computers and mobile devices; functionality to store base year value and compute trending for all properties on the Assessment Roll; and a case management pilot designed for secure taxpayer self-service access.

ISD, the Assessor and Oracle are working in partnership to establish the architecture and provision the multiple technical environments needed to support the Assessor Modernization Project. In a truly collaborative effort, partner departments including The Chief Executive Office/CIO, ISO, Auditor Controller, Treasurer and Tax Collector, Registrar-Recorder/County Clerk and County Counsel participate in an Advisory Steering Committee to discuss collaboration, integration points, shared functional roadmaps, and budget.

Phase I was successfully completed in November of 2016, establishing 6 application environments consisting of more than 120 application servers and 30 databases. Over the past 16 months, Oracle and ISD staff have worked hand-in-hand with the Assessor to successfully complete development of Phase II foundational modules, including complex data structures and business rules needed to support property taxation in the County.

In order to provide enhanced security, environmental sustainability and advanced hardware and software resources, the AMP was migrated to the County’s new unified DataCenter1 in December of 2017. ISD worked with the Assessor’s Office to accommodate an aggressive implementation schedule and successfully address minor implementation issues that resulted from migration of multiple vendor systems along with a highly complex technical environment, and large data storage requirements to establish a secure and technologically advanced environment for the successful completion of AMP future phases.
