CC Regular Session Meeting Date: 07/09/2019 Submitted For: Len Linton, Engineering/Public Works By: Len Linton, Engineering/Public Works Information 7. 4. Title: Adopt Resolution #19-162 Accepting Bids and Awarding Contract for Improvement Project #19-00, 2019 Cracksealing Improvements Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #19-162 accepting bids and awarding a contract for Improvement Project #19-00, 2019 Cracksealing Improvements. Background: Crackseal improvements are completed on numerous public street segments annually to cost-effectively maximize the life of the bituminous pavement. 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, reducing future pavement damage due to wet subgrade soils, especially during freeze -thaw cycles. 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 for the 2019 Cracksealing Improvements were prepared in-house as part of Staff's normal duties. A total of 24.20 miles of public streets are proposed to receive crackseal improvements in 2019. These street segments were selected based on their maintenance history, age, and Pavement and Surface Evaluation Rating (PASER). Per the City's typical maintenance schedule, these street segments are generally composed of streets that were constructed, reconstructed or received overlay improvements 3 years ago, or were last sealcoated 7 years ago. One -Year Suspension of Sealcoat Program The purpose of sealcoating is to protect existing bituminous pavement from damage caused by stormwater runoff, ultraviolet rays from the sun, and petroleum deposits left by vehicles. The City of Ramsey has generally sealcoated between 13 and 23 miles of City streets each year, and has done so for many years. This year, Staff and the Public Works Committee recommended suspending the sealcoat program for one year for the following reasons.
