A memorial stone at the old village site, a boulder from the Soonwald, unveiled on 1 June 1980, commemorates Rehbach's 500 years of history there.

After the airfield at nearby Pferdsfeld was given up by the military in 1998, the municipality of Rehbach, together with the town of Bad Sobernheim (within whose limits the airbase lay after the acquisition of the outlying villages) and the municipality of Ippenschied founded the Planungsverband Konversionsmaßnahmen Pferdsfeld, a group whose goal was to convert the facility to civilian use.

A community centre with a youth room, a slaughterhouse and firefighting facilities arose, new houses were built and in 1970 the first villagers moved in.

[3] As at 2 January 2014, there are 48 full-time residents in Rehbach, and of those, 36 are Evangelical (75%), 2 are Catholic (4.167%), and 10 (20.883%) either have no religion or will not reveal their religious affiliation.

[6] The German blazon reads: In Rot ein blauer Wellenbalken, belegt mit einem silbernen, goldgehörnten Rehbock.

The municipality's arms might in English heraldic language be described thus: Gules a fess wavy azure surmounted by a roebuck springing argent attired Or.

This leads southwards to neighbouring Daubach (several hundred metres), linking with Kreisstraße 22, which itself links with Kreisstraße 20, which runs southwards to Bundesstraße 41 at Bad Sobernheim, serving which is a railway station on the Nahe Valley Railway (Bingen–Saarbrücken).
