"The trucks will be on Blackbridge Rd six days a week and we fear the effects on cyclists, children and horse riders who use our road to get to the Riverhead Forest and [take] riding lessons on properties along here.".
The fill is to be a mixture of contaminated and non-contaminated waste, Mrs Syme said.
Dirtworks' application is to be heard by independent planning commissioners on Tuesday and Norsho's Bulc could be heard in late March, Mrs Symes said.
Norsho Bulc emphasised the demand in Auckland for landfills in its proposal.
"It is estimated that for every new residential dwelling that is constructed, approximately 25cu m [solid] of material is excavated which has to be removed off-site," a report said.
"In addition to the residential construction there are commercial and civil engineering operations, road improvements being completed where surplus fill material is required to be removed off-site."
A council report on the Dirtworks application said the adverse effects would be no more than minor.
"Effects associated with noise, dust, vibration, duration of works, traffic safety, the ability of Blackbridge Rd to accommodate the additional traffic movements, amenity values, visual landscape, erosion and sediment control, significant natural areas, natural hazards, discharge of contaminants, quality and mauri of water and cumulative effects have been assessed and the applicant has proposed measures to ensure the effects on the environment resulting from the activity will be avoided, remedied or mitigated."
When asked about the society's concerns, the Auckland Council referred the Herald to the applications from the landfill businesses.
