A swathe of land on a proposed 480 home development site on the outskirts of Helston has been ruled out for housebuilding due to noise from Flambards.

A noise survey conducted at the proposed HX2 site found that even if a six metre earthwork was built to deflect sound from the theme park and a nearby tip, sound levels would be higher than recommended domestic limits if houses were built less than 100 metres from Gays Hill on the south west corner of the site.

The survey, which was conducted during a busy bank holiday weekend when sound levels were expected to be at their peak, was commissioned by Cornwall Council after Flambards' owner Ian Cunningham raised concerns that noise complaints from residents in a new development could lead to constrictions being placed on his business, or even to the closure of the attraction.

found that "the sound of children’s voices, music and hum of the go-kart engines can be heard along the southern boundary of the site," with the highest highest levels opposite the go-kart track, and that "these levels will only occur when Flambards Experience is open and the rides full and this will be very much the minority of the time across the year," while noise from the waste and recycling centre was "even less of an issue."

The report also reaffirms statements made to the committee during a meeting at the beginning of April, that problems with noise are not insurmountable and while the affected land could not be used for housing, it could provide open green space, amenity areas including games fields, or lagoons for water storage, features which are allowed for in the current plans.

At the earlier meeting a representative of the developers David Martin had said as it was an outline proposal the number and location of houses on the site could be changed.

Town councillors agreed to support the proposal, provided that the sound mitigation work is carried out and vehicle access is relocated to the north west corner of the site and an extra exit is considered at the May Tree roundabout, while Councillor Judith Haycock said she would like to see better pedestrian access from the estate to Clodgey Lane.

A decision on the proposal is expected to be made by Cornwall Council's strategic planning committee on July 2.
