Managing Tomorrow’s Resources Today MEMORANDUM Page 7 of 11 RWC_Memo_19Dec2024 the City’s Master Fee Schedule. This calculation represents an estimate of the value of the City’s public right-of-ways. The City’s parklet fee is similar to the rate that neighboring cities charge. For example, San Bruno charges $12.68 per square foot 1 while Mountain View charges $10.00 per square foot. Figure 5. Right of Way Encroachment Value Alternative 7.Vehicle Impact Analysis. Road maintenance is based on deterioration. While roads will deteriorate if simply left unused, most deterioration is associated with use. The damage caused by vehicles increases much more than proportionately with size and weight. Hence, maintenance costs are greater for trips made by heavy vehicles. A single, large truck can cause as much damage as thousands of automobiles, and a truck’s configuration can affect the amount of damage as well. If the load is spread over more axles, allowing for less weight on each wheel, then damage is reduced.2 Refuse Vehicles are generally some of the heaviest vehicles regularly operating on city streets. Accordingly, these vehicles contribute significantly to the cost of maintaining those streets. Pavements are engineered to carry the truck traffic loads expected during the pavement design life. Truck traffic, which includes refuse vehicles, transit vehicles, trucks, and truck-trailer vehicles, is the primary factor affecting pavement design life and its serviceability. Passenger cars and pickups are considered to have negligible effect when determining traffic loads that damage the pavement. City streets are categorized as residential, commercial, and arterial and each category is engineered to withstand the projected truck traffic volume. Pavement damage also varies with weight distribution. Three factors which affect weight distribution are the number of axles, the weight on each axle, and the spacing between axles. The American Association of State Highway and Transportation Officials (AASHTO) developed a unit of measure to convert various axle configurations of different vehicles on the roadway and their loads. Loads include the weight of the vehicle and the contents of the vehicle in transit. One Equivalent Single Axle Load (ESAL) represents the amount of damage to the pavement structure that is the equal to one pass of a single 18,000-pound, two-tire axle with all four tires inflated to 110 psi. Street design standards often use a Traffic Index (TI) for specific types of streets. Each TI has a corresponding ESAL value. 1 This rate is calculated by applying the parallel parking space area of 160 square feet to the annual permit fee of $2,028. 2 Rufolo, Cost-Based Road Taxation, Cascade Policy Institute, Policy Perspective #5, November 1995.
