1.3 SDC Rate Schedule 1.3.1 Formula The transportation SDC for an individual development is based on the total cost per trip (including the street and bike components) and the number of trips attributable to a particular development. This calculation is as follows: Cost per Trip X Number of Development Trips = SDC for Development where: Cost per Trip = (Cost per Trip (street) + Cost per Trip (bicycle), and Number of Development Trips = Trip Generation Rate X Pass-by Adjustment X Nodal Development Adjustment X Development Size 1.3.2 Assigned Trip Generation Rates The standard practice in the transportation industry is to use Institute of Transportation Engineers (ITE) trip generation rates to ultimately determine the SDCs for individual qevelopments. ITE trip rates by land use are based on studies from around the country, and in the absence of local data, represent the best available source of trip data for specific land uses. Pass-by trip adjustments to ITE trip rates have been applied to the ITE trip rates. Also referred to as linked trips or trip chaining, pass-by trips refer to trips that occur when a motorist is already on the roadway (as in the case of a traveler stopping by a fast food restaurant on the way home from work.) In this case, the . motorist making a stop while "passing by" is counted as a trip generated by the restaurant, but it does not represent a new trip on the roadway. Pass-by adjustments are provided only when three or more studies as reported in the ITE manual have established an average range for percent of pass-by trips for a particular use category contained in the Table 3. If the minimum number of studies is not available, no pass-by adjustment is assigned. An applicant may choose to submit a request for an alternative pass-by adjustment through the Alternate Calculation method. Except when the City Transportation engineer has approved an applicant's election to use the Alternate Calculation method or an alternative pass-by adjustment, the City Transportation Engineer shall apply the description that most nearly describes the type of development proposed ITE trip rates by land use as published in Table 3 to determine the trip rate to be assigned to the proposed development. A transportation trip rate may be assigned by the City Transportation Engineer should a proposed use not be accurately represented by one of the published transportation use codes. In addition, trip rates for published use codes may be alternatively assigned as best available information in the case that a revised ITE trip rate is published prior to an administrative modification to the Transportation Trip Rate Table (Table 3).
