[5] There were campaigns for Ridgewood's separation from Merriwa as far back as 1994, not long after the Carnegie Estate had been built by developers Town and Country Holdings.

[6] Although the request was rejected, the City supported the excision of the estate from Merriwa, leading to the creation of Ridgewood four years later.

The northern half of Ridgewood, "The Vistas", is a new development by Satterley, marketed as a part of the "Brighton Estate" that covers the adjoining suburbs of Butler and Jindalee.

Ridgewood is primarily a residential suburb, with a BP service station in its south-west and almost no other facilities or retail establishments.

[10] The West Coast Language Development Centre is the only education establishment in Ridgewood, one of five schools in Western Australia that serve language-disabled children.

[12] The Mitchell Freeway forms the suburb's eastern boundary, with interchanges at Lukin Drive and Hester Avenue.

Connolly Drive runs along Ridgewood's western boundary and provides a road link into Joondalup and the Mitchell Freeway.
