8 Engineering staff has established the following OCI categories to describe the conditions of the roadways: Adequate – Overall Condition Index (OCI) 70.01 – 100.00 Marginal – Overall Condition Index (OCI) 40.01 – 70.00 Problem – Overall Condition Index (OCI) 0.00 – 40.00 Photographs of representative road sections for each OCI category are included as Figure 3. Additional photos can be found in Appendix F . EXISTING ROADWAY PAVEMENT CONDITIONS Most of the roadway system at this time is in f air condition, but it is approaching a critical stage meaning it is approaching a stage in which a reconstruction is needed . The average city standard (a) roadway is 20 years old and has been sealcoated at least once. The average non -standa rd (b) roadway is 30 years old and has undergone either a seal coat or cold in place recycle :AA AbreakdownAofAtheACity’sAroadwayAoverallA condition is: Overall Condition Index Mileage Percent of System Adequate Category – 70.01 – 100.00 69.26 miles 72.5 % Marginal Category – 40.01 – 70.00 13.77 miles 14.4 % Problem Category – 0.00 – 40.00 12.57 miles 13.1 % (a) “Standard roadway” means a roadway within the City of Lino Lakes, which is in general conforma nce with the City standard as set forth in Section 302 of the City Code.

They are commonly recognized as lacking a critical component such as strength, adequate drainage or concrete curb and gutter but may have some of all of these or other components. Appendix A is a map of all City roadways showing their OCI classification. The specific OCI rating for each roadway segment is contained in Appendix B.
