T'he actual bituminous pavement width between the curbs is <br /> � 28'4". Costs are also listed in Appendix C for streets wider or narrower than 33'. <br /> Estimated utility costs for new water main, storm sewer extensions and sanitary sewer repairs are <br /> � listed separately in Appendix B. <br /> � All cost estimates include a 10% condngency factor and 30% indirect costs. Indirect costs include <br /> engineering design, construction inspecdon, legal, aci�ni.nistrative, testing and interest on the bond. <br /> ' <br /> � Assessments <br /> � Street improvement projects, whether new or reconstruction, are generally assessed totally or in part <br /> � to the abutting property owners. These costs are typically assessed on a front foot basis. The City of <br /> � Centerville has not developed a policy for assessing street reconstiuction type projects. One purpose <br /> of this Pavement Management Study is to suggest an assessment policy. This policy can be adjusted ; <br /> � or modified as necessary to meet the needs of the City: <br /> , Table 6— Suggested City Assessment Policy <br /> � Infrastructure Property <br /> ; Imarovement Owner Citv <br /> � Street Seal Coat 0% 100% <br /> Street MilUOverlay 10°l0 90% <br /> � Street Reconstrucrion 25°Jo 75°1'0 <br /> Concrete Curb & Gutter* 75°10 25% <br /> ;� Sanitary Sewer Repairs 0% 100% <br /> Water Main** 100% 0% <br /> Storm Sewer SQ% 50°!0 <br /> � Sidewalks 25% 75% <br /> � * Applies only where no curb and gutter existed before reconstruction <br /> , <br /> ** All costs over and above a 6" diameter aze financed by City Trunk Fund <br /> , Centerville Pavement Managernent Study 22 <br /> I — -- <br />
