Much of Tuggerah's residential housing was built in the 1970s–90s as the suburb grew around
the railway station and Westfield. Original copper and galvanised pipes are now 30–50 years
old and failing.

Parts of Tuggerah sit within the Tuggerah Lakes floodplain. After heavy rain, Tuggerah Creek
rises and stormwater systems back up into private property — basements,
garages, and sub-floor areas cop the worst.
