Officers are trying to track down all signs which are on council-owned land or property that are old, incorrect, out of date, confusing have spelling or grammar mistakes, are in a bad state of repair or perhaps are no longer needed.

They could be anywhere as the council has a number of buildings and sites, ranging from libraries and leisure centres to parks and industrial estates as well as many schools, offices, civic buildings and one stop centres.

Leeds City Council changed its logo in recent years, but not all its signs were changed at the time, mainly because of the cost. Services and departments have also moved buildings or sites and so some older versions of the logo have remained in place.

It is a huge task to find out where they all are and residents of the city are being asked to lend a hand.

The authority wants pictures of dodgy signs emailed or sent via text message along with details of where they are and what the photographer thinks is wrong.

Information will then be put into a database so each one can be considered individually and then replaced, repaired or removed if appropriate.

Mobile phone images can be sent to 07518 219 449 – charged at normal operator text message rates – or emailed to talkingpoint@leeds.gov.uk.

Coun Richard Brett, executive board member with responsibility for resources said: "Our signs need to be clear, up to date and informative – and most are.

"Unfortunately, there are some which aren't and those are the ones we want to identify and possibly change, but this doesn't mean replacing signs for the sake of it.

"It's the first time we've asked for photographs to be sent in via text or email and I hope that encourages residents across Leeds to help us."
