ARDEN HILLS CITY COUNCIL WORK SESSION - JANUARY 18, 2022 2 Public Works Director/City Engineer Swearingen reported that Attachment B showed the 2021 PCI directly from the automated survey when it was conducted in May of last year. This was prior to the 2021 PMP in the Hazelnut neighborhood and other street related projects from last year. Attachment C shows the PCI from the beginning of this year (2022). This map was generated after entering data into the pavement management software. Staff enters all pavement projects into the software including the reconstructs, full depth reclamation, seal coats, crack sealing etc. The software then depreciates the values over time using an algorithm. The PCI raised 2.6 points over last year's construction season. This jump is likely due to the large area of streets within the PMP project. The project scheduled for 2022 on Snelling Avenue North and the Arden Oaks neighborhood should show a similar improvement in the PCI since those large sections of street are currently rated so low. Public Works Director/City Engineer Swearingen explained that streets rated with a good PCI 65 or higher are candidates for preservation methods. These methods include crack sealing, seal coats and fog sealing, which are included in the scope of work with the Coon Rapids JPA contract. Large area patching and pothole filling is handled by our public works department. Streets with a rating of 45 to 65 fall into the category for rehabilitation methods which include mill and overlays or full depth reclamation and overlay. We do have a significant amount of payment within that range. Anything below 45 would call for at least a full depth reclamation project or a complete reconstruction because the pavement has met the end of its useful life. Public Works Director/City Engineer Swearingen stated that using this information staff is proposing the next PMP projects through 2030. These projects will be spaced two years apart, and will mainly consist of mill and overlay and full depth reclamation types of rehab projects. In 2022, will be the Snelling Avenue North improvements project that also includes Cummings Lane. Arden Oaks Drive and Arden Oaks Court are included in the Arden Oaks street improvements project. They will be brought to Council soon for approval of plans and specs and go out for bid in February. The 2024 project includes Colleen Avenue, Norma Avenue, and Briar Knoll. Those streets are localized west of Hamline and east of Snelling Avenue. The 2026 PMP is the Karth Lake neighborhood which is in the northeast corner of the city. 2028 PMP is in the southeast quadrant of the city and the 2030 PMP includes areas around Red Fox Road, Grey Fox Road, Cummings Park Drive and Stowe Avenue. Councilmember Holmes asked if Lake Valentine Road construction was still in 2022. Public Works Director/City Engineer Swearingen replied that he added in the short section just in front of the school which will be done by the school this summer. Those improvements are being done and funded by the school. Public Works Director/City Engineer Swearingen mentioned that these estimates for 2024 and beyond are just desktop estimates and are conservative numbers. Councilmember Holmes said she thought the Lake Valentine Road project was deferred until when some of the city work was done. Public Works Director/City Engineer Swearingen said they took some pavement cores along that stretch and noticed that the pavement section is actually in pretty good shape. The issues lie
