LANDGATE —
FLOOD MAPPING
120. Hon SALLY TALBOT to the
parliamentary secretary representing the Minister for Lands:
(1) Is the
minister aware that the use of new local government flood mapping data has
significantly increased home insurance premiums for people living near the
Collie River in Eaton?
(2) Has
Landgate changed the way it assesses or compiles flood-mapping data; and, if
so, when did this change take place and what does it involve?
(3) How many
Eaton properties are built in locations designated by Landgate's
mapping as lying in the one-in-100-year flood fringe?

I thank the honourable member for some notice of the
question.
(1) No.
(2) No.
Landgate has recently revamped its web page for a suite of satellite remote
sensing–based products, including FloodMap, which make this service
easier to find and access. The difference between the FloodMap service
accessible via the new website and the one-in-100-year flood line is that
FloodMap provides an observation of current flood events based on satellite
images. The one-in-100-year flood line is a calculated flood line based on
expert understanding of flood behaviour, including weather events, soil
drainage and landforms. The Department of Water is the custodian of the one-in-100-year
flood fringe. Landgate is the custodian of the FloodMap service.
(3) The
Department of Water is the custodian of the one-in-100-year flood line.
Landgate has no control over custodial datasets such as this.
