Master Address Database & Enterprise Addressing System

Web-based system for managing an authoritative, master address database of building addresses tied to Assessor’s parcels and City’s street centerline network


Reduce addressing errors. Eliminate duplication. Increase functionality

The Situation

Every municipal department (city or county) depends on addresses.

  • Each department has at least one vertical address-based application
  • Each department enters these addresses with their own procedures and conventions
  • Each vertical application stores and uses addresses differently
  • Each application has its own address mapping solution

The Problem

Multiple address systems lead to errors and inconsistencies.

  • Less accurate tax assessment and collection problems
  • Emergency dispatch services can show up in the wrong place
  • Difficulty matching customer service requests or complaints to addresses
  • Duplicated efforts, reduced efficiency and non-validated / bad data

The Solution

Centralized, authoritative, addressing system that spans all departments.

  • Assessor matches permits to parcels by address
  • 911 dispatches emergency services to correct addresses
  • Public works and utilities matches complaints to addresses
  • Business and spatial validation rules automatically maintain data integrity

Fast, intuitive, manageable, and secure

Master Address Database used by all municipal departments 
Consistent, reliable, timely addresses across departments

Farallon’s Master Address Database and Enterprise Addressing Framework provides an authoritative, centralized database of building addresses for use throughout an organization so you can more easily compare and relate information with locations across databases and departments.

The Enterprise Addressing System (EAS) also known as a Master Address Database or Master Address Repository, reduces errors and prevents duplicative effort by enabling all departments within a City or organization to access address data from a single source. The secure, web-based EAS solution using Open Source technology, incorporates the geospatial location of addresses, allowing address points to integrate with other georeferenced data such as and the City’s street centerline network, Assessor parcels, and census information.

A customizable, off-the-shelf solution

Farallon customizes the capabilities of the master address database, the address maintenance workflow, and the web services needed to support the integration of your existing GIS and multi-jurisdictional business systems such as Planning and Zoning Departments, Building Department, the Department of Public Works, and Public Safety. We then ETL your address lists into the master address database schema. Spatial capability enables the EAS to intelligently apply business logic and spatial validation rules to automatically maintain the integrity of the system.

Increase Revenue, Reduce Costs & Decrease Risk

This address management system is flexible, extensible and cost-effective. It enables more accurate tax assessments, enhanced City construction and redevelopment planning and streamlined environmental analysis as well as saving substantial expense through reduction in errors and duplication.
