3. EXISTING CONDITIONS <br />3.1 Existing Streets <br />The existing right-of-ways along the street segments proposed to receive overlays as part of this <br />project generally vary in width from 60 to 80 feet. The paved street segments vary in width from <br />24 to 32 feet. All streets in this project were constructed with bituminous pavement and curbing, <br />and many of the street segments contain storm sewer. The thickness of the bituminous pavement <br />sections vary. <br />City staff visually inspects each public street segment throughout the City, typically on an annual <br />basis, to determine the pavement condition. Staff uses the Pavement and Surface Evaluation <br />Rating (PASER) method to assign a numerical rating between 1 and 10 to each street segment. <br />Streets rated with a 1 are considered to be failed pavements in need of complete reconstruction, <br />while streets rated with a 10 are considered to be in excellent condition therefore requiring no <br />improvement. The street segments proposed to receive overlays in 2015 had 2014 PASER <br />ratings of 3 and 4 making them excellent candidates for bituminous pavement overlays, which <br />will extend the life of the pavement approximately 20 years. <br />Based on the manner in which the existing pavement is deteriorating, staff does not believe there <br />are any issues with subgrade soils that will negatively impact the design life of the proposed <br />improvements. Staff also does not believe that groundwater will be a concern for any of the <br />proposed improvements. <br />3.2 Watermain <br />Watermain does not exist under any of the streets in the proposed project areas. <br />3.3 Sanitary Sewer <br />Sanitary sewer does not exist under any of the streets in the proposed project areas. <br />3.4 Storm Sewer/Drainage <br />Storm sewer exists under several of the streets in the proposed project areas, but it is not <br />proposed to complete any significant repairs or storm sewer construction as part of this project. <br />Feasibility Report <br />2015 Street Maintenance Program, Division B: Overlay Improvements <br />City of Ramsey Project No. 15-00 <br />Page 3 <br />
