3PARKS & TRAILS COUNCIL of MINNESOTA <br />What our Ratings Don’t Measure <br />TrailheadsBridges & Culverts <br />Routine Maintenance <br />Our ratings only answer a simple question: How smooth are Minnesota’s <br />State Trails to ride? While we use this question as a proxy for the overall <br />condition of each trail, there are several components of a safe, well- <br />maintained trail system that our ratings don’t capture. Our ratings do <br />not consider the integrity of trail bridges, culverts or the underlying <br />trail foundation. Our ratings do not consider the condition of <br />parking areas, interpretive displays or signage. And our ratings <br />only consider day-to-day upkeep to the extent it impacts the <br />smoothness of the ride (e.g., debris on an unswept trail is <br />rougher to ride than a freshly swept trail). See Appendix A for <br />more details on project scope and limitations. <br />How to Understand Our Ratings <br />Trail feels like new and <br />provides near-ideal <br />conditions for bicyclists <br />and inline skaters. Small <br />blemishes and crack <br />sealing may be present <br />in isolated areas but do <br />not negatively impact <br />user experience. <br />Trail o�fers a <br />comfortable ride for <br />bicyclists and inline <br />skaters, with infrequent <br />bumps and depressions. <br />Trail may require minor <br />rehabilitation and crack <br />sealing in isolated areas. <br />Trail has intermittent <br />bumps and depressions, <br />but is tolerable to ride <br />for the majority of <br />bicyclists. Some sections <br />may be di�ficult for <br />inline skaters. Trail may <br />require moderate <br />rehabilitation and crack <br />sealing in several areas. <br />Trail has frequent <br />bumps and depressions <br />and is uncomfortable to <br />ride for bicyclists. Many <br />sections may be di�ficult <br />for inline skaters. Trail is <br />at the end of its life and <br />requires major <br />rehabilitation. <br />Trail is in complete <br />disrepair with very <br />frequent bumps and <br />depressions. Trail may <br />be suitable only for <br />mountain and fat-tire <br />biking. Trail is past its <br />useful life and likely <br />needs to be entirely <br />rebuilt. <br />Good Fair Poor Very Poor <br />TRI 30-45 TRI 45-60 TRI 60-75 TRI >75 <br />Excellent <br />TRI < 30
