Charlie Schaefer November 5, 1992 Page 2 The warehouse trip generation rate determined by the Institute of Transportation Engineers is 4.88 trip ends per day per 1,000 square feet. This is quoted from the Institute of Transportation Engineers, "Trip Generation", Fifth Edition, 1991, rates for warehouse land uses included as Attachment 2. It provides a description of warehousing land uses as follows. "Warehouses are primarily devoted to the storage of materials; they may also include office and maintenance areas". Caltrans estimates the daily trip rate for warehouses at 4.5 trip ends per day per 1,000 square feet as indicated on Attachment 3. This is very similar to the Institute of Transportation Engineers rate. This is quoted from "Fifteenth Progress Report on Trip Ends Generation Research Counts", Caltrans, December, 1983. Most of the detailed studies used to determine the Caltrans rate are also attached. They provide only a sketchy description of the actual projects. However, it can be noted that the trip rates are based upon total traffic entering and exiting each warehouse facility. Virtually all warehouses will include some type of office space. For example, Caltrans study No. 212 was conducted at a McGraw—Hill book distribution center in Novato, California. It describes this project as follows. "A book distribution center adjacent to Highway 101 in Novato isolated from other developments. Major activities include warehousing, book distribution, and office work". This particular project had, a trip generation rate of 2.2 trip ends per day per 1,000 square feet. The 8.33 trip ends per 1,000 square feet used for industrial storage land uses in the City of Colton traffic mitigation fee program is more consistent with triprates quoted for general light industrial land uses in the Institute of Transportation Engineers and Caltrans publications. In considering the appropriate traffic mitigation fee for this project, it should also be remembered that the project site was, until recently, outside the City of Colton sphere—of— influence and was not considered a candidate for contributing to the traffic impact fee at all. This project will not impact the City of Colton street system and, therefore, will not contribute to anticipated congestion requiring the various capitol projects anticipated to be funded by the traffic impact fee. The collection of any fee from this project can be considered a bonus to the City of Colton. If you have any questions regarding this recommendation, please do not hesitate to contact me. Thank: you for the opportunity to assist you with this project. Sincerely ours, Keith B. Higgins, CE kbh:mm enclosures 30489 exp. 3/31/96, TE 1385 exp. 12/31/93
