Meeting Date: 01/23/2018 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #18-027 Approving Plans and Specifications and Authorizing Advertisements for Bids for 2018 Crackseal and Sealcoat Improvements, Improvement Project #18-04 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #18-027 approving plans and specifications and authorizing advertisements for bids for 2018 Crackseal and Sealcoat Improvements, Improvement Project #18-04. Background: Long-term Street Maintenance Program Various city street segments receive crackseal and/or sealcoat improvements annually to maximize the life of their pavement sections. Cracksealing protects pavement by preventing stormwater runoff from seeping through cracks in the pavement and joints between the pavement and concrete curb and gutter and utility castings. This reduces future pavement damage due to wet subgrade soils, especially during freeze -thaw cycles. Sealcoating protects pavement from the negative effects of stormwater runoff, ultraviolet rays from the sun, and oil -based products deposited on the pavement by vehicles. The City's typical maintenance schedule for public streets includes: • Crackseal 3 years after construction, reconstruction, or overlays. • Crackseal and sealcoat 7 years after construction, reconstruction, overlays, and sealcoats. • Overlay 20 years after construction, reconstruction, or overlays. • Reconstruct 60 years after construction or reconstruction. While this is the typical maintenance schedule, it is important to note that Staff reviews the condition of all streets annually and adjusts the schedule of maintenance operations based on actual pavement conditions. Plans and Specifications Plans and specifications for the 2018 Crackseal and Sealcoat Improvements were prepared in-house as part of Staff's normal duties. A copy of the final plans are attached to this case. A total of 22.71 miles of public streets are proposed to receive crackseal and/or sealcoat improvements in 2018. Approximately 7.15 miles of City streets are proposed to receive crackseal improvements in 2018. In accordance with the City's typical maintenance schedule, these street segments are primarily composed of streets constructed or
