CMP Part 4A. Transportation Plan <br /> cost effective than waiting until the pavement is in poor condition when it is necessary to perform <br /> more costly maintenance or reconstruction. <br /> An effective preservation programs addresses pavements while they are still in good condition. A <br /> cost-effective treatment in a timely manner will restore the pavement almost to its original <br /> condition. By doing so, the cumulative costs of such treatment are substantially less then <br /> reconstruction or major rehabilitation over the life of the pavement. In addition the disruption of <br /> traffic is less for more frequent and minimal treatments in comparison to larger construction <br /> treatments. A proper Pavement Preservation program consists of three primary components: <br /> Table 4A-8 Maintenancer .

The pavement management system tracks pavement condition to help <br /> decision making regarding the cost / benefit trade-offs of road reconstruction versus lower level <br /> maintenance strategies. The Program is used by the County to develop priorities for pavement <br /> maintenance projects on county roads. (See Hennepin county Transportation Plan for details on <br /> their Maintenance program) <br /> Orono Road/Pavement Maintenance <br /> The primary need for Orono Roadways in the coming years is maintenance. Over the last decade <br /> Orono had underfunded road maintenance and replacement operations and therefore the roads have <br /> fallen in to disrepair. Orono adopted a pavement management system in 2014 to identify roadway <br /> maintenance priorities. The pavement management system tracks pavement condition to help <br /> decision making regarding the cost / benefit trade-offs of road reconstruction versus lower level <br /> maintenance strategies. While a certain share of the City's annual levy is dedicated to Pavement <br /> Management Fund (PMF) each year for maintenance, much of the city's infrastructure is aging. <br /> This is particularly challenging in the older,more developed parts of the city. Many of these roads <br /> are old, were not initially designed to support the land use forms desired today, are not pedestrian <br /> or bicycle friendly, and are in need of both infrastructure and land use revitalization. Also a lack <br /> of adequate funding for preventive maintenance activities has resulted in a great deal of deferred <br /> maintenance. This deferred maintenance has undesirable consequences from a financial as well <br /> City of Orono Community Management Plan 2020-2040 Part 4A, Page 15 <br />
