Methodology for Calculating Street Maintenance Fees
The current methodology is based on the following:
- Ties the street maintenance element of the fee to a 5-year maintenance and reconstruction plan prepared by the City of Tigard
- Uses actual road maintenance and repair projects on City streets, not state or county routes.
- Tailors the fee to the local data
- Sets a target revenue goal of $800,000 annually (established in 2003)
- Allocates the costs of the arterial projects to the non-residential uses
- Splits the costs for the collectors on a 50-50 basis with residential and non-residential uses sharing the costs equally. The rationale for splitting the costs in this fashion is that many of the collectors do traverse residential areas and collect traffic from those areas to feed the other collectors and arterials in the system.
- Allocates the costs for neighborhood routes and local streets to residential uses
- Allocates the costs for residential uses on a per unit basis for both single family and multifamily units.
- Uses the minimum parking space requirements based on the Tigard Development Code for non-residential uses with a 5-space minimum and 200-space maximum. Like the trip generation rates, the parking space requirements are based on size of building and type of use. However, this approach takes into account businesses that draw from a larger area than just Tigard. The argument is that above 200 spaces, the traffic is more likely regional traffic, which comes via the state routes. The 5-space minimum is to establish a minimum amount for the billing to compensate for the costs of preparing and mailing out the bills.
