Specifications include, but are not limited to: Snow Plowing – The Zone Representative shall determine the need for snow plowing services by the presence of ice and/or snow on the roadways in amounts that would impede travel or create hazardous travel conditions, such as when snow accumulation exceeds three inches (3”). The successful Proposer(s) shall plow to bare pavement whenever feasible, at least two (2) lanes wide. Snow shall be “pushed back” after the road has been plowed in order to prevent accumulation of snow in traveled lanes. All snow plowing equipment used by successful Proposer(s) shall be equipped with appropriate warning lights, placards, or signs identifying it as equipment that makes frequent stops and backing movements. The successful Proposer(s) shall not alter, modify, remove, or relocate any existing sign, marker, delineator, or striping without the approval from County’s Contract Administrator. Plowing must allow for the proper functioning of drainage facilities. Culverts and off drains shall be kept open to allow for adequate drainage.; Road Sanding – The need for road sanding services shall be determined by presence of ice and/or snow on the roadways. Sand shall be broadcast in those areas of the roadway where ice accumulates in order to increase traction. No snow plowing or sanding services shall be performed prior to specific contact from the Road Zone Representative and authorization by the County’s Contract Administrator or designee. Authorization to perform snow plowing and sanding services will be by phone call and email follow up from the Contract Administrator or his designee.
