8.d August Engineering UpdatesSCANDIA City of Scandia Q & MLENK Engineering Updates 9/20/2016 Engineering italics = old information 2016 Street Improvements ➢ Contractor's Request for Payment No. 3 was approved at the August 2016 City Council Meeting. ➢ Minor punch list items are scheduled to be completed by the end of September and then final project closeout documents can be prepared for project closeout. • 2016 Seal Coat and Crack Filling Project ➢ All work has been completed other than the second sweeping and 4" double solid line (yellow paint) on 2201h Street N. ➢ Contractor's Request for Payment No. 1 is on the agenda as a separate business item. • 2016 Property Tax Report/Resources ➢ The Minnesota League's annual Property Tax Report and data tables are now available. In the report, you'll learn that the trend of increasing property values continued in Minnesota cities overall. You'll also find out about other market value and tax capacity trends and get an update on current policy issues related to the property tax system. http://www.Imc.org/page/1/PropertVTaxReportSeptOct2016.*sp Road Ratings ➢ All the road ratings have been updated along with an updated colored map showing the road ratings. The ratings were updated using the PASER Road Rating System which is a visual system to rate the condition of pavements based on rating number 10 (excellent) through 1 (failed). • Guidance for dealing with Cell Towers and Small Cell Technologies ➢ With the increase in the use of cell phones and other mobile technology, cities are getting more requests for placement of new cell towers and for placing cell technology and distributed antenna systems (DAS) on city property and in public rights of way. It's important for cities to proactively review their regulations to ensure they are consistent with federal law, while still retaining control over the deployment of structures and the use of rights of way. http://www.Imc.org/media/document/1/celltowerssmallcelltechanddas.pdf?inli ne=true I& w ¢ LAKE 202nd a hmL jA j r PASER PAVEMENT RATINGS ® 9-10 m 7-a 5-6 3-4 1-2 196th ST 9 'P J f \ C� ItiW U - r 2 r LAKE --ty�t AN RO CIR.

The rating scale ranges from 10—excellent condition to 1—failed. Most pave- ments will deteriorate through the phases listed in the rating scale. The time it takes to go from excellent condition (10) to complete failure (1) depends largely on the quality of the original construction and the amount of heavy traffic loading. Once significant deterioration begins, it is common to see pavement decline rapidly. This is usually due to a combi- nation of loading and the effects of additional moisture. As a pavement ages and additional cracking develops, more moisture can enter the pave- ment and accelerate the rate of deterioration. Look at the photographs in this section to become familiar with the descriptions of the individual rating categories. To evaluate an individual pavement segment, first determine its general condition. Is it relatively new, toward the top end of the scale? In very poor condition and at the bottom of the scale? Or somewhere in between? Next, think generally about the appropriate maintenance method. Use the rating categories outlined below. Finally, review the individual pavement distress and select the appropriate surface rating. Individual pavements will not have all of the types of distress listed for any particular rating. They may have only one or two types. z RATING 10 O Excellent H RATING 6 z O Good V F_ RATING 4 LU Fair 5 LU > RATING 2 a- Poor PAVEMENT AGE In addition to indicating the RATINGS ARE RELATED TO NEEDED MAINTENANCE OR REPAIR surface condition of a road, a given rating also includes a Rating 9 & 10 No maintenance required recommendation for needed Rating 8 Little or no maintenance maintenance or repair.
