<br />Special 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 />Street Width: Case SpecifIc <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 of the road <br /> <br />All new street construction and street reconstruction in Arden Hills will include concrete <br />curb and gutter for a number 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 of the 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 (PC!) 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 PCl 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 />Opportunities to improve water quality oflakes downstream of street <br /> <br />City of Arden Hills Pavement Management Program <br /> <br />Pagel <br /> <br />4/12/2007 <br />
