Santa Clara County Assessor Office Online Tax Assessment Viewer

Santa Clara County Assessor Office Online Tax Assessment Viewer

Client: Santa Clara County Assessor Office



Silicon Valley and the world’s leading high-technology companies lie at the heart of Santa Clara County.  Rapid growth and a red-hot housing market have made it imperative for home owners, potential home buyers, community development professionals, and the staff of local governments to rapidly and easily access the latest tax assessment status for properties throughout the county.  County Information technology staff and IT staff within the Assessor’s Office needed to provide their constituents with these property data.  To meet tight project deadlines and budgets, and to deliver a web-based application using the latest, most robust development technologies, county staff turned to Farallon for support.


Farallon staff partnered with the county to:

  • Provide Internet users the ability to view property assessment records without requiring a visit to the Assessor’s Office during business hours
  • Improve upon the functionality of the Assessor’s existing green-screen, main frame tax assessment viewing application
  • Integrate new website into the County’s emerging web portal technical framework

Farallon delivered a web solution that presents up-to-the-minute property assessment information for the current and past three tax years.  Farallon’s fully J2EE, Java Server Pages based site provides secure Internet access to over 2 million records related to property values, tax assessments, situs addresses, and tax rate areas for the entire Santa Clara county.  Our team of database and web development experts built and deployed a robust Oracle 9i database designed to retrieve information incredibly quickly, without sacrificing data security and maintainability.  Within 10 days of deploying the site, County IT staff noted that the Tax Assessment web site delivered by Farallon was the second most accessed site in the County, easily sustaining 3000 hits per day with response times under 2 seconds.

To provide geographic context, Farallon integrated the Assessment Viewer website with the online property GIS we developed for the Santa Clara County Planning Office.  This effort leveraged the County’s investment in web-enabled GIS without the need to re-code a single line of code in the Planning Office GIS application.
