<br />Pavement Management Program Page 2 <br /> <br />SDecial Cases: <br />Definition: Streets which do not fit into any of the three above descriptions and have <br />a very low usage, (1-3 residences), streets which provide secondary access (ie alleys) <br />or streets defined by extreme limitations due to narrow ROW, topography etc. <br />(0.3 miles throughout City) <br />Recommended Street Width: Case Specific <br /> <br />. <br /> <br />Additional Considerations for Street Width Determination <br /> <br />Arden Hills is a community with a wide variety of neighborhoods, each with special <br />conditions which must be taken into account when considering reconstruction of streets. The <br />residential and neighborhood street widths listed above are desired goals but exceptions to <br />these widths will be considered by the City Council on a case by case basis. A number of <br />factors in addition to street classification will be considered including: <br />Topographical constraints (steep hills, lakes, etc.) <br />Existing street widths <br />Existing average daily traffic volumes <br />Existing right-of-way width <br />Existing trees <br />Pedestrian use ofthe road <br /> <br />All new street construction in Arden Hills will include concrete curb and gutter for a number <br />of reasons: . <br />Provide a stable maintenance edge for plowing and sweeping operations <br />Reduce plow damage to yards and mailboxes <br />Protect the edge ofthe bituminous surface from deteriorating <br />Channel storm water runoff away from street <br />Reduce erosion from boulevards/lawns <br /> <br />All new street construction in Arden Hills will be structurally designed for 9 ton loading <br />thereby eliminating the need for spring load restrictions (allowing year round access) and <br />slowing the rate of deterioration of the pavement system. <br /> <br />How Streets are Selected for Reconstruction or Overlav Work <br /> <br />The City Council select streets for reconstruction based on a variety of factors starting with <br />the Pavement Condition Index (PCI) of the pavement. The City Engineer conducts a field <br />survey of streets about once every 2 years at which time a PCI rating is calculated for each <br />street in the City. The PCI is a numeric reflection of the surface characteristics of the <br />pavement including potholes, cracking, rutting, etc. <br /> <br />Several other factors which will be considered in order to determine the best candidates for <br />street reconstruction are, but not limited to, the following: <br /> <br />Condition/effectiveness of existing surface drainage system <br />Condition of underground water and sewer system <br />Whether a street meets recommended standards for curb and gutter and width <br /> <br />. <br />
