Controversial plans to build a Harris Academy in South Wimbledon have been recommended for approval.

Earlier this year, Mayor of London Sadiq Khan identified 50 of the most polluted schools in the capital.

On the list was Merton Abbey Primary School, which occupies land on the same street that the new Harris Academy would be built on.

But in the document recommending the High Path development be approved, it says there is nothing to worry about.

Despite these assurances, the Harris Federation will have to fork out thousands of pounds to ensure the air quality levels remain acceptable.

"The submission has satisfactorily demonstrated that issues of air quality, noise, contamination, traffic generation, flood risk and drainage and sustainability are addressed and acceptable or can reasonably be addressed," the council document read.

"Whilst the proposal has demonstrated that it would be acceptable in terms of air quality, the council’s environmental health officer has advised that a financial contribution of £11,500 should be secured by way of a s.106 agreement to provide for on-going monitoring of the proposed mitigation measures over the next 5-6 years."

But air quality wasn't the only concern.

Abbey Recreation Ground sits on the opposite side of a main road to where the school would be built.

These playing fields will be used by the students if the development is approved.

Once again the Harris Federation will have to pay up to ensure student safety.

"The council’s highways team have set out that some form of junction improvements to secure suitable pedestrian crossings are required in order to safely accommodate pupils walking to the Abbey Recreation Ground and have identified necessary highway improvements," the document read.

"The financial contribution to secure these works has been calculated to be no more than £70,000."

Despite criticisms about the development, which include comments from former cabinet member for schools in Merton, Peter Walker, who said it would be a "crime committed against the children," Merton Council has repeatedly said the need for more school places was overwhelming.

This was once again echoed in the council document prepared for tomorrow's meeting.

"The London Borough of Merton has a statutory duty to deliver additional school places," it read.

"The proposed development would provide a major new secondary school meeting a defined need arising from significant growth in a cohort of children that will be of secondary school age in the coming years.

"The delivery of a school of the size required to meet known needs has proved challenging both in terms of identifying suitable sites so as to avoid encroachment onto protected open space and through the site selection process the council is now committed to this site."

A final decision will be made at the planning applications committee meeting tomorrow, which is due to begin at 7.15pm.
