The winter road clearing financial and operational performance objectives were established in coordination with the City’s Public Works - Operations prior to the commencement of our field work. The results are based on our detailed review of selected monthly vendor payment certificates and data analytics on available GPS records for vendor salters/plow trucks over the 2017/2018 and 2018/2019 seasons.
