What is "meadvale"

__NOTOC__ Meadvale or less commonly Mead Vale is a southern residential suburb that straddles borders of Redhill and Reigate in the borough of Reigate and Banstead in Surrey, and one of two which do so. The average elevation of the district is higher than the centres of each of the towns – Meadvale is bisected east-west by the Greensand Way at the top of a moderately low section of the Greensand Ridge. Its population, as broadly defined on its ward definition, is 3,090 spread over based upon the most recent national census.
