CMP Part 4A. Transportation Plan <br /> <br /> <br />City of Orono Community Management Plan 2020-2040 Part 4A, Page 13 <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 /> <br />Table 4A-8 Maintenance <br />Type Description Examples <br />Preventive <br />maintenance <br />A planned strategy of cost-effective treatments to <br />an existing roadway system and its appurtenances <br />that preserves the system, retards future <br />deterioration, and maintains or improves the <br />functional condition of the system (without <br />significantly increasing the structural capacity). <br />Chip sealing <br />Slurry or micro surfacing <br />Thin overlay <br /> <br />Routine <br />maintenance <br />Day-to-day activities that are scheduled by <br />maintenance personnel to maintain and preserve <br />the pavement at a satisfactory level. <br />Cleaning of ditches & structures <br />Pavement markings maintenance <br />Crack filling <br />Pavement patching <br />Minor <br />rehabilitation <br />Minor Structural enhancements that extend the <br />service life of an existing pavement and/or <br />improve its load carrying capacity. <br />Overlays <br />Mill and Overlay <br />Geiger, D.R., Pavement Preservation Definitions, FHWA Memorandum dated 12 September 2005. <br /> <br />County Road/ Pavement Maintenance <br />Hennepin County implemented a pavement management system in 1996 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. 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 /> <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 />as a user perspective, and effective planning is needed to ensure that quality infrastructure is <br />sustained over time. Streets that receive no preventive maintenance are often beyond repair in just <br />ten years, while streets that are properly maintained at critical stages in the life-cycle can last up
