After the subgrade excavation is completed for the sidewalk, a geotextile fabric will be <br />placed to separate the existing underlying soft materials from the granular materials. One <br />foot of select granular material or "sand cushion" will be placed on the geotextile fabric <br />to provide a firm base for the 4.0 -inches of concrete pavement. <br />4.1. Permits and Approvals <br />Construction of the sidewalks and lighting will disturb over one acre and will require a <br />National Pollution Discharge Elimination Systems (NPDES) General Storm Water <br />Permit (MNR 100001), which must be obtained by the City of Saint Anthony from the <br />Minnesota Pollution Control Agency (MPGA). <br />4.2. Detour Routes <br />The project will not require significant excavation in the existing boulevard area. <br />However, a supply of significant volumes of select granular base and concrete pavement <br />materials will be required. This effort will increase loaded truck traffic on the streets <br />adjacent to the construction area. Detours are not expected to be required to direct traffic <br />around the construction zones. The City will need to notify users of the increased truck <br />and construction activity. In order to accommodate the property owners along the <br />excavated boulevards and driveway areas, temporary parking on the adjacent streets may <br />be necessary during the periods of time when vehicle access is not possible. <br />5. FINANCING <br />5.1. Opinion of Probable Construction Cost <br />A detailed breakdown of the Opinion of Probable Cost for the project is included in <br />Appendix B. The Opinion of Probable Cost incorporated the average construction costs <br />experienced during 2005 and 2006, and includes a 15% contingency factor. <br />Administrative costs are projected at 25% of the construction cost and include <br />engineering, legal, financing and other administrative costs. The total estimated project <br />cost is $679,640. <br />5.2. Funding Sources <br />The total project cost is projected to be approximately $679,640. Funding for the project <br />will come from the City's Street and Utility Reconstruction Funds and Municipal State <br />Aid Funds. <br />2007 SIDEWALK AND STREET LIGHTING IMPROVEMENT PROJECT <br />FEASIBILITY REPORT <br />CITY OF ST.
