Appendix 2E Truck Traffic Issues Among the comments heard during the public engagement work were complaints related to truck traffic. These stem form concerns about the number of garbage trucks in an alley or on a street during a week, and the reasons for concern included noise, wear and tear on streets, safety, and pollution. The following data were gathered on the issue of garbage trucks and traffic. References cited are at the end of the summary. Reduced wear and tear on streets • Reduction of road impacts of overweight vehicles, especially during spring road restrictions when roads are the most vulnerable to damage as the frost moves out of the ground. - "As they fill up on the route, many refuse collection vehicles operate overweight, especially during the spring months when waste generation rates increase but road weight limits may be at their lowest...Further, the number of overweight vehicles using roadways increases the potential for paving damage." (GBB, pg V-2) - "The damage that garbage trucks inflict on City streets is magnified in the spring when road restrictions typically restrict other trucks from using the same streets." (Bonestroo) - "During the road restriction period, most refuse vehicles exceed the allowable • axle load limits. Because of the variable nature of refuse, these vehicles are rated by volume capacity rather than by weight. Minnesota is said to have some of the lowest allowable load limits when road restrictions are in effect; therefore refuse vehicle manufacturers are not inclined to design vehicles to meet Minnesota standards. Haulers generally acknowledge in some cases when road restrictions are in effect, their fully loaded vehicles exceed the allowable load limits. Tertiary (tag) axles and duel wheels are available on some refuse vehicles of more recent design, but they are not generally used in this area. Although these auxiliaries reduce the load on a road, they do not guarantee compliance with road restrictions....Mn/DOT will issue special permits to haulers who apply for such permits. These permits increase the allowable limit by 2,000 pounds/axle. Certain communities that enforce road restrictions may grant exemptions to refuse trucks operating on their residential streets. This practice is most common in cities with organized collection." (Roseville, pg 21) - "The number of exceptions to weight limits has direct bearing on the potential for damage to pavement. An increase in the frequency of overweight vehicles increases the risk of damage." (Chanhassen, pg 22) • Reduction of relative impact on local streets of collection vehicles - "According to research conducted as part of the City of Chanhassen Organized Collection Study, MSW collection vehicles have road impacts 4y
