June 25, 1992 File No: 520-019-30 Honorable Mayor & City Council City of Arden Hills 1450 West Highway 96 Arden Hill s, MN 55112 RE: PODLASEK DRIVEWAY NORTH SNELLING AVENUE Dear Council Members: This letter 1s intended as a reply to the June 21, 1992 letter from Mr. Francis Podlasek regrading his driveway. Mr. Podlasek's driveway prior to the project had a slope of 2.4% from the corner Of his garage slab to the roadway and a slope of 3.2% from a point 40 feet into the driveway to the road. Our street reconstruction lowered the centerline of # the street approximately 6 inches, and the establishment of a standard crown lowered the edge of road approximately 10". This cut was made to provide a uniform street grade torward Royal Hills Drive and to match topography on both sides of the road. A straight prOfile on his driveway, therefore, would prOVide a slope of 3.2% from the garage slab to the roadway and a slope of 5.7% from a point 40 feet into the driveway to the road. As a comparison, Department of Transportation and municipal engineering gUidelines indicate that driveway grades of 10% are very reasonable for residential driveways and are commonly used as design criteria. Our first discussions with Mr, Podlasek occurred on Saturday, October 19. 1991. when the concrete aprons were being placed. Mr. Podlasek was very concerned that his existing driveway slope would not be exactly maintained and that we should provide the same driveway slope even if it meant rebuilding his driveway back to his existing concrete slab. At Mr. Podlasek's direction, we flattened out the concrete apron as much as possible to provide positive drainage and serve his driveway, Further discussions were held on October 26 and October 29, 1991 between myself, our inspector, Mr. Podlasek and the Contractor to discuss paving of his driveway from the apron to the right-Of-way. Mr. Podlasek indicated he was considering replacement of his entire driveway, possibly with concrete, due to the condition of the existing pavement. We indicated that the intent of the plans was to match the existing driveway with bituminous surfacing, but we could extend the - - bituminous patching Quantity in his driveway to improve the slope to his - satisfaction. This extension would have been to a point 40 feet from the road - and prOVided a 5.7% slope. This work was to be done in conjunction with Mr. Podlasek's plan to reconstruct his entire driveway. It was our understanding over the winter that this was the plan for construction this Spring. 1959 SLOAN PLAce, SUirE ~oo, ST. PAUL, MINNliSOTA5S117 612-774,6021 ----.-
