• • Engineering staff has established the following OCI categories to describe the conditions of the roadways: Adequate — Overall Condition Index (OCI) 70.01 -100 Marginal — Overall Condition Index (OCI) 40.01 -70 Problem — Overall Condition Index (OCI) 0 -40 Photographs of representative road sections for each OCI category are included as Figure 3. EXISTING ROADWAY PAVEMENT CONDITIONS Most of the roadway system at this time is in good condition, but is approaching a critical stage. The average city standard (a) roadway is 9 years old and has been sealcoated once. The average non - standard (b) roadway is 19 years old and has been sealcoated twice. A breakdown of the City's roadway overall condition is: Overall Condition Index Mileage Percent of System Adequate category - 70.01 -100 53 miles 63% Marginal category - 40.01 -70 20 miles 24% Problem category 0 -40 11 miles 13% (a) "Standard roadway" means a roadway within the City of Lino Lakes, which is in general conformance with the City standard as set forth in Section 302 of the City Code. They are commonly recognized as having a properly graded hard surface with normal crowns, width, strength, acceptable drainage systems and concrete curb and gutter on both sides. (b) "Non- standard roadway" means a roadway located in the City of Lino Lakes, which is not in general conformance with the City standards 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 or all of these or other components. 411 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. 7 -130-
