The Geographic Information Systems (GIS) department maintains detailed cadastral mapping information that tracks exact lot lines, properties, right of ways, setbacks, zonings and the location of utilities like sewer and water, manholes, and fire hydrants. GIS also tracks design-build projects such as new developments, buildings and bridges.

GIS information is primarily used internally by the City of Chilliwack for planning, zoning and infrastructure management purposes, however information is also made available to other federal and provincial government agencies, developers and emergency service providers such as the fire department and RCMP.

Residents can access Touch Screen Maps at the cashier counter and the Municipal Development department at City Hall.
