<br />CASe # d. <br /> <br />UPDATE ON DIRT DRIVEWAY PAVING <br />By: Steven Jankowski, City Engineer <br /> <br />Background: <br /> <br />City Council directed staff at the May 8, 2007 City Council meeting to prepare information <br />relative to the goal of eliminating unpaved driveways within the City. The benefit of such a <br />goal would be the reduction of sediment migrating onto paved City streets and into the <br />storm drainage system. Secondary benefits would be improved neighborhood appearance <br />and higher property values. The purpose of this case is to provide the Committee with cost <br />information and to project the financial impact of this proposal on both property owners <br />and the City ifit should chose,to participate financially to encourage this goal. <br /> <br />In an effort to quantify the number of unpaved driveways in the City the engineering <br />department intern conducted a survey during periods of travel between proj eets and during <br />rain days when construction inspection was interrupted or suspended. The surveyed area <br />included essentially the entire City excepting the more recently developed sewer and water <br />areas and commercial areas where the paving of driveways has been included as a <br />provision in subdivision development agreements. A City map was marked to document <br />the areas surveyed and to avoid recounting the same area twice. A summary of the <br />findings of this survey is as follows: <br />. There were a total of 498 unpaved driveways identified <br />. 366 unpaved driveways were the primary driveway for the property <br />. 132 unpaved driveways were secondary driveways <br />. 19 driveways were generally paved but had a short unpaved length between the <br />paved driveway and the street <br />. The range of unpaved driveway widths range between 10 feet and 35 feet, however <br />the largest percentage of drives is either 15 or 20 feet wide. <br />. Driveway lengths were not measured, however addresses were recorded and <br />lengths could be measured from a.erial surveys if more price cost information is <br />desired. <br /> <br />Based upon a local paving contractor's estimate of$2.50 per square foot for grading and <br />paving an unpaved driveway the following table illustrates the costs for paving individual <br />driveway. <br /> <br />Length <br />10ft <br />15 ft <br />20 ft <br />25 ft <br />30 ft <br /> <br />Driveway Paving Cost <br />Width <br />50 ft 75ft 1 00 ft <br /> <br />$ 1,250 $ 1,875 $ 2,500 <br />$ 1,875 $ 2,813 $ 3,750 <br />$ 2,500 $ 3,750 '$ 5,000 <br />$ 3,125 $ 4,688 $ 6,250 <br />$ 3,750 $ 5,625 $ 7,500 <br /> <br />5 <br />
