Davis Street -Doolittle Drive Intersection Improvements Traffic Impact Fee Justification - AB 1600 Report Page 5 of 7 Analysis of Benefit Assessments for Proposed Traffic Improvements of Davis Street and Doolittle Drive by TJKM Traffic Engineers dated December 23, 2004 (Traffic Report), calculated the proportion of traffic growth generated in the proposed impact fee areas to all additional traffic using the Davis-Doolittle intersection between 2003 and 2025 by completing an origin and destination analysis. As shown in Table 1, TJKM has determined, on a square foot basis, the amount of traffic added by new development in the proposed impact fee areas.

DETERMINE HOW THERE IS A REASONABLE RELATIONSHIP BETWEEN THE NEED FOR THE PUBLIC FACILITY AND THE TYPE OF DEVELOPMENT PROJECT ON WHICH THE FEE IS IMPOSED (GOVERNMENT CODE SECTION 66001 (A)(4)) A reasonable relationship exists between the need for the proposed intersection improvements and the type of development because the proposed intersection improvements were identified based on the projected increase in traffic generated due to anticipated increase in development in the traffic impact areas, by the year 2025.
