Y:\Data\Proj20\10-101\Policy\Sidewalk & Driveway.Doc 1 of 2 04/01/2010 POLICY / GUIDELINE DEPARTMENT OF PUBLIC WORKS CATEGORY: ENGINEERING NUMBER: 12 FROM: TOBY GINDER P.W.C. APPROVAL: 1-8-96 DATE: REVISED: 02-22-10 SUBJECT: ASSESSMENT FOR MAINTENANCE OF SIDEWALKS / DRIVEWAYS A. SIDEWALK REHABILITATION Sidewalk may be rehabilitated via mud jacking or saw cutting as part of a sidewalk maintenance or street improvement project and 100% of the cost thereof assessed to the adjacent property owner if: 1. The sidewalk, at a crack or joint, is vertically displaced more than ½” and less than 1½” measured within approximately 1" of the adjacent surface. 2. Visual evidence indicates prolonged water ponding on the sidewalk surface. 3. The sidewalk surface does not conform to requirements of the ADA law. B. SIDEWALK REPLACEMENT Sidewalk will be removed and replaced as part of a sidewalk maintenance or street improvement project and 100% of the cost thereof assessed to the adjacent property owner if: 1. The sidewalk contains a crack or gap which is more than 1" wide measured ½” below pavement surface. This criteria applies also to a gap between the sidewalk and adjacent driveway or driveway apron. 2. The sidewalk surface of any section is spalled or deteriorated more than 4 square inches measured ½” below pavement surface or more than 2 square inches measured 1" below pavement surface. 3. Sidewalk is heaved or subsided more than 4" beyond the average sidewalk grade line measured adjacent to the displaced sidewalk squares even though there may be no abrupt vertical displacement at a joint. 4. Two or more of the above defects are present on a given section and are each within 75% of the stated minimum measurements. 5. Visual evidence indicates water ponding on the sidewalk surface longer than 24 hours. 6. A city Engineering Technician determines the sidewalk is a safety hazard for general pedestrian or disabled users. 7. The sidewalk surface does not conform to requirements of the ADA law. 8. Cracked sections of sidewalk adjacent to a section being rehabilitated or removed will also be marked for removal due to the probability of damaging the cracked section during work on the adjacent section. Such cracked sections will not be replaced unless one or more of the above described deficiencies exists. ---PAGE BREAK--- Y:\Data\Proj20\10-101\Policy\Sidewalk & Driveway.Doc 2 of 2 04/01/2010 C. DRIVEWAY APRON REPLACEMENT 1. Driveway aprons will be removed and replaced as part of a concrete maintenance or street improvement project and 50% of the cost thereof assessed to the adjacent property owner if: a. The apron is a part of or contiguous to the project; and b. The apron to be replaced is surfaced with concrete or asphalt; and c. The apron meets the following criteria for replacement: 1) The apron adjacent to the sidewalk is vertically displaced more than 1" causing a potential hazard to pedestrians on the sidewalk. 2) The apron adjacent to the sidewalk is vertically displaced and creates significant impedance to drainage from the sidewalk to the street. 3) The apron must be removed incidental to the reconstruction of the adjacent street. (Examples: to match new grades; to allow slip-form curb and gutter construction.) 4) The City Engineering Technician determines the condition of the apron poses a public nuisance or safety hazard to the general public. 2. The cost for removal and replacement of an existing apron for any reasons not listed above or for construction of a new apron will be assessed 100% to the adjacent property owner. D. DRIVEWAY REHABILITATION OR REPLACEMENT 1. A portion of driveway adjacent to sidewalk will be rehabilitated or replaced if the surface is vertically displaced more than 1" causing a potential hazard to pedestrians on the sidewalk. E. ASSESSMENTS 1. A city Engineering Technician will perform a survey prior to construction to determine the limits of concrete sidewalk or driveway apron meeting the criteria listed herein. 2. The amount assessed will include the applicable contract costs for concrete rehabilitation, removal, base course, new concrete, and grass restoration. An additional 15% of the contract costs will be assessed to cover engineering, testing and administrative expenses. 4. Additional sidewalk or driveway apron areas may be rehabilitated or replaced as part of a sidewalk maintenance or street improvement project if the adjacent property owner requests the additional work and agrees to pay the cost. 5. Per a decision of the Public Works Committee on July 8, 2002, the City will pay for maintenance of inter-block sidewalks.
