 <br /> <br /> <br />Feasibility Report <br />2024 Street Improvement Project <br />City of St. Anthony Village <br />WSB Project No. 023088-000 Page 4 <br />3. Existing Conditions <br />3.1 Sanitary Sewer <br />Roads identified in the 2024 Street Improvement Project were previously reconstructed in the 1990s and <br />early 2000s. At the time the streets were reconstructed, the majority of the sanitary sewer was replaced <br />with polyvinylchloride (PVC) pipe, including the replacement of sanitary sewer services to the right-of- <br />way. The record drawings indicate the existing sanitary sewer consists of 9-inch-diameter vitrified clay <br />pipe (VCP) along the following roadways: <br /> <br />x Roosevelt Street Northeast from 37th Avenue Northeast to 34th Avenue Northeast <br />x Edward Street Northeast from 35th Avenue Northeast to 34th Avenue Northeast <br />x Harding Street Northeast from 36th Avenue Northeast to 34th Avenue Northeast <br /> <br />An internal inspection (televising), with a specially designed television camera, will be completed with final <br />design to determine the structural condition of the existing pipe. <br /> <br />3.2 Water Main <br />The existing water main within the project corridor was also upgraded at the time the roads were <br />reconstructed to ductile iron pipe (DIP) including the replacement of water services up to and including <br />the curb stop. <br /> <br />3.3 Storm Sewer <br />Stormwater throughout the project corridor is currently conveyed with concrete curb and gutter to <br />adjacent storm sewer systems. The majority of the stormwater from the roadways is collected and <br />conveyed to Harding Pond. Stormwater along Wilson Street is directed through Silver Point Park and <br />ultimately collected within the trunk storm sewer within Highway 88. <br /> <br />3.4 Streets <br />Streets within the proposed mill and overlay improvement area consist of 30-foot-wide (measured back of <br />curb to back of curb) urban roadways and are experiencing various severities of distress. <br /> <br />Pavement cores taken indicated existing asphalt thicknesses ranging from 3 1/2-inches to 6 1/2-inches, <br />with a top lift of approximately 2-inches. The majority of the core samples were in fair to good condition <br />with some raveling noted. The streets exhibited chipseal stripping with transverse and longitudinal <br />cracking. <br /> <br />The pavement forensic report can be found in Appendix C. <br /> <br /> <br /> <br />69
