I TRAFFIC IMPACT STUDY SCOPE OF WORK Date: April 24, 2010 Consultant: Branch Engineering 310 Fifth Street Springfield, OR 97477 Project Assumptions: . Chevron Gas Station & Convenient Store Southeast Corner of Gateway Street and Kruse Way ITE Codes: Gasoline/Service Station (945 & 853) Existing Size: 6 Pumps & 989 square feet Completed Size: 6 Pumps & 3,384 square feet Access: Via Gateway Street and Kruse Way Completion Date: Estimated 2011 . Project Name: Location: Land Uses: . . . General: The proposed development will more than triple the size of a convenient store on a site, while leaving the gasoline station unmodified. This will add trips to the adjoining . intersection of Kruse Way and Gateway Street, which has long been known for its frequent crash history and has also had one of the highest injury rates in the city. Consequently, as the development will increase the safety hazard there, in accordance with SDC 4.2-105(A)(4)(c), a TIA is required. The study should address all the criteria outlined in Springfield Public Works Department policy (See enclosed S.O.P.P. #T-6.l), except that certain elements of the study may be confined to the scope outlined below. As the City of Springfield Council has temporarily reduced the performance standard to below LOS D for the Gateway Street intersections with both Kruse and Beltline, no advantage will be gained in studying the capacities of these intersections outside of their impact on safety. This study will consequently need to be completed with operations in mind more than capacity. Trip Distribution and Assignment: The site traffic would have two primary routes available for access to/from Springfield's street network, and that is through a driveway on Kruse Way and one on Gateway Street, the latter of which is shared with the Super 8 motel adjoining the site to the south. The distribution pattern of existing traffic at these driveways is likely a reasonably reliable indicator of future site-trip distribution when comparing the two access points. Summarize recent three-year traffic accident data. The traffic accident data can be obtained from City or State. The analysis should include (but not limited to) total number of accidents by type (pDO, injury and fatal, rear end, head-on, sideswipe etc.), total number offatalities, high accident locations, accident patterns, road deficiencies and mitigation measures. Study Locations: . Intersection of Gateway Street and Kruse Way . The site access points at Kruse Way . The site access point at Gateway Street Date Received: Planner: AL Page 1 of2 . . In the place of analyzing the Beltline-Gateway intersection directly, please measure the maximum queue length based on the cycle length of said intersection. These measurements shall be taken three times every IS minutes in the a.m. and p.m. peak hours. They should be measured from a fIxed point thatcan be reproduced and directly related to the Gateway driveway and Kruse Way intersection. Trip Generation: Use the averaged data from the lIE Trip Generation Manual from lIE Codes 945 & 853 as discussed and derived in Attachment A. The independent variable will be trips per 1000 square feet gross floor area Traffic Crash Analysis: Summarize most recent three-year crash history along both the site access pomts on Gateway Street and Kruse Way within 200 feet each direction from beyond the site's borders. Include this Scope a/Work in the appendix a/the Traffic Impact Study Date Received: Planner: AL Page 2 of2
