A petition has been launched calling for a full review of Farnham’s town centre road changes to determine whether they have delivered the improvements promised.

Residents and businesses are being asked to back calls for Surrey County Council, Farnham Town Council and Waverley Borough Council to assess the impact of the Farnham Infrastructure Programme once the major works are complete.

The petition says that after almost two years of closures, diversions and disruption, the public deserves clear evidence of whether the changes have improved the town.

It stresses that campaigners are not seeking a verdict while work is still under way, with Castle Street among the areas yet to be completed.

Instead, they want the authorities to publish clear measures of success before the work finishes and carry out a detailed review once traffic, footfall and trading patterns have had time to settle.

The review would examine whether congestion and journey times have improved, whether traffic has been displaced onto surrounding roads and whether air quality has improved across Farnham.

Campaigners also want the impact on independent businesses assessed through measures including footfall, vacancy rates, business openings and closures and trading conditions.

The petition calls for the full post-completion review to take place around 12 months after the work is finished.

It says accessibility should also be considered, including the experience of pedestrians, disabled people, cyclists, bus passengers, motorists and families with pushchairs, as well as whether the new road layout is capable of coping with future growth.

Campaigners also want the authorities to commit to an action plan if the evidence shows that elements of the scheme are not working as intended.

The petition says its purpose is not to oppose investment in Farnham, but to make sure the town receives the improvements it was promised.

“If the changes work, that should be demonstrated and celebrated,” it says. “If parts don’t work, they should be acknowledged and addressed.”

The petition is now seeking support from Farnham residents and businesses.
