CITY OF ST. PETERS 2021 PAVEMENT MANAGEMENT PROGRAM FOREWORD The purpose of the City of St. Peters pavement management program is to provide well-maintained, high quality streets, sidewalks and traffic control systems at the lowest reasonable cost. Planned levels of maintenance must be carefully correlated with available funds to achieve the best possible level of service across the City. This program book lists the streets, sidewalks, street signs, pavement markings and traffic signals scheduled for repair or replacement during the coming season in each political ward of the City. Prior to the individual ward sections are summary lists for scheduled sidewalk, concrete and asphalt street repairs, sign replacements, traffic signal improvements, and pavement marking operations. All projects are listed in order of need. Listings of all projects, in the general order they will be performed, will be available at the Street Department website, www.stpetersmo.net. These listings will be updated periodically as the projects are completed, or conditions warrant a schedule change. In addition to the 2021 repair projects, listings of tentative repair and maintenance projects for 2022, which are currently un-funded, are shown. Street, sidewalk and traffic system repair and maintenance are hazardous and stressful jobs, which may not be understood by the general public. Operations are performed in the public road right-of- way during hot weather, and often under heavy traffic conditions. We thank those individuals who give their dedication and best effort in carrying out the details of this program. 2021 Pavement Management Program i Forward TABLE OF CONTENTS Foreword ............................................................................................................................. i Table of Contents ................................................................................................................ ii Pavement Management System Strategy ........................................................................ 1-2 Sidewalk Maintenance Program ..................................................................................... 3-6 Enhancement Maintenance Projects ...................................................................................7 2021 Asphalt Overlay Projects ..................................................................................... 8-10 2021 Concrete Slab Replacement Projects ................................................................. 11-12 2021 Curb and Sidewalk Replacement Projects ......................................................... 13-14 2021 Joint and Crack Sealing Projects ........................................................................ 15-19 2022 Proposed Asphalt Overlay Projects ................................................................... 20-22 2022 Proposed Concrete Slab Replacement Projects .......................................................23 2022 Proposed Curb and Sidewalk Replacement Projects ......................................... 24-26 2022 Joint and Crack Sealing Projects ........................................................................ 27-29 Pavement Marking and Sign Programs ....................................................................... 30-31 2021 Sign Replacement Projects ................................................................................ 32-51 2021 Pavement Marking Projects ............................................................................... 52-56 2021 Traffic Signal Projects .............................................................................................57 Ward 1 Projects and Pavement Ratings ...................................................................... 58-62 Ward 2 Projects and Pavement Ratings ...................................................................... 63-67 Ward 3 Projects and Pavement Ratings ...................................................................... 68-72 Ward 4 Projects and Pavement Ratings ...................................................................... 73-77 2021 Pavement Rating Summary .............................................................................. 78-197 2021 Pavement Management Program ii Table of Contents PAVEMENT MANAGEMENT SYSTEM STRATEGY The Transportation and Development Services Group is responsible for the maintenance of approximately 547 lane miles of pavement. Approximately 195 lane miles (36%) are constructed of asphalt and 353 lane miles (64%) are constructed of concrete. As the City’s pavement continue to age, more effort and financial resources will be required to maintain the current level of service condition. The American Concrete Pavement Association states the average useful life of properly installed concrete pavement is 35 years. The Asphalt Institute states that the average useful life of properly installed asphalt pavements is 17 years. Both organizations state that periodic crack sealing and miscellaneous spot repairs are generally necessary before full replacement or resurfacing is required. It has been the City St. Peters’ experience that major maintenance is generally required for asphalt streets, between the ages of 10 to 12 years, and for concrete streets, between the ages of 15 to 20 years. This increased frequency in maintenance is primarily due to less than optimum sub-grade conditions. Prior to 1998, concrete and asphalt streets in the City were constructed directly on a compacted soil sub-grade. Since 1998, all new pavement placed in the City of St. Peters must be constructed on four inch thick aggregate rock base. The addition of aggregate rock base provides a harder, more stabile base, thus extending pavement life. In 2017, the City of St. Peters joined the Eastern Missouri Pavement Cooperative (EMPC), a group of St. Charles area municipalities and agencies that work cooperatively to improve the quality of concrete pavement through improved specifications and staff training, more stringent material testing requirements and elimination of certain types of aggregate materials that are not suitable for use in areas that treat with salt and other deicing chemicals. While EMPC concrete mixes cost between $2.00 and $4.00 more per cubic yard compared to non EMPC concrete mixes, savings in future labor, traffic disruption and materials from less small scale replacement and patching will more than offset increased material costs. The graphs on the following page show the age distribution of the City’s pavements: Asphalt Pavement Age Distribution (Years) 12-25 <12 4% 2% 25-35 18% >36 76% 2021 Pavement Management Program 1 Pavement Management System Strategy Concrete Pavement Age Distribution (Years) <5 0% 5-15 >35 14% 24% 16-25 24% 26-35 38% Referencing the aging distribution graphs on the previous page, it can be seen that 0% of concrete streets within the City of St. Peters have met or exceeded their expected useful life of 35 years and 100% of the City’s concrete streets have reached an age where some slab replacement is required. By contrast, 97% of the asphalt streets have reached an age that requires periodic overlays be performed. In order to provide planned and orderly pavement maintenance, the City of St. Peters has instituted this pavement management program, which uses a computer database containing maintenance records of each city street. This database includes the name, length, width, street material, dates and quantities of maintenance operations, and current pavement condition or street rating. All streets in the City of St. Peters are rated using the “PASER” rating system, developed by the University of Wisconsin. The “PASER” system rates pavement based on the number and type of pavement distresses. Pavement is rated on a scale of 1 to 10, with 10 being new or like new. The database is sorted, based on the “PASER” ratings, to formulate lists of streets that require maintenance or repair, and to establish maintenance priority and schedule. In addition, the City of St. Peter’s resident concern system is used to identify locations where street repair or maintenance may be necessary. It is the goal of the City of St. Peters’ Pavement Management Program to achieve a 12-year overlay cycle for asphalt streets, and a 35-year replacement cycle for concrete streets. To achieve this goal, the City of St. Peters must overlay approximately 118,000 square yards of asphalt pavement and replace approximately 65,200 square yards of concrete pavement annually. Currently, the program is funded to overlay approximately 136,408 square yards of asphalt pavement, and replace approximately 22,950 square yards of concrete pavement. The City’s annual pavement maintenance funding also includes additional repair treatments such as crack sealing, joint repair, and pothole patching. Also part of the City’s annual pavement management program is the annual concrete curb and gutter replacement program. Curb and gutter replacement is typically performed on asphalt streets prior to planned overlay. The curb and gutter replacement program is funded to replace up to 5% of the curb and gutter present on a street scheduled for asphalt overlay. Currently the program is funded to replace 7,008 lineal feet of damaged concrete curb and gutter. 2021 Pavement Management Program 2 Pavement Management System Strategy SIDEWALK MAINTENANCE AND INFILL PROGRAM The City of St. Peters maintains approximately 501,600 lineal feet (95 miles) of sidewalks and 507 accessible ramps within its corporate limits. These sidewalks and accessible
