Shoreview's Street Renewal Policy (and resulting Pavement Management Program) was created in 1985 and most recently amended in 1996. The intent of the program as stated in the policy is "to create a permanent program to manage, finance, and implement the reconstruction or rehabilitation of the streets within the City of Shoreview." The policy also directs that the City maintain a "detailed inventory of all City streets, which shall measure and document the condition of all streets and assist the evaluation by the City Engineer of anticipated street improvements." Further, the policy directs that the inventory be updated every three years, and that the revised information be used in the development of the Capital Improvement Program.
Conceptually, cost effective pavement management can be described as doing the right thing to the right street at the right time. Our pavement management program groups streets into three general classifications: 1) those which benefit from continued minor maintenance (i.e. seal coating, crack filling), 2) those which are appropriate to rehabilitate by full depth reclamation with emulsion, and 3) those which should be totally reconstructed prior to performing any minor maintenance. The classification of streets is based upon their Pavement Condition Index (PCI), which is a score on a scale of 1 to 100 with 100 representing a new pavement (1 to 3 years old) with no flaws. The average PCI of all of the streets in the City over time is a good indicator of how well we are keeping up with the natural deterioration of the pavements.
With our current pavement management program, we can predict how pavements deteriorate, and determine which rehabilitation strategy is appropriate. Severe pavement rehabilitation strategies such as total reconstruction are costlier per mile than seal coating, overlays, etc.; our approach to pavement management will reveal when it may be time to let a bad street go, and spend those same dollars on more appropriate strategies elsewhere on the street system. The software we are utilizing also helps ensure that maintenance strategies are utilized at times when they will actually extend the life of pavement and make the best use of your tax dollars.
Similar to any automated management system, our Pavement Management Program is intended to assist City staff in the decision making process. Many factors beyond pavement condition can influence the timing of street maintenance or rehabilitation, including drainage, sewer or water needs, existence of curb and gutter, available funding and location. Staff considers the information from the PMP when recommending modifications to the Capital Improvement Program and for setting current/future funding levels.
