Hilliard Lane (River Road Elementary School) Property - Eugene, Oregon C&A Project Number 20211201.00 June 23, 2022, Revised August 12, 2022, Revised October 10, 2022 Page 6 5. Reasonable worst-case property development in the proposed PL zone designation generates an additional 49 daily and 15 PM peak hour trips over the current R-1 zone designation. 6. The potential development trip generation increase of 15 PM peak hour trips is considered de minimus as it represents less than 5% of the traffic entering the River Road/Hilliard Lane intersection in the 2035 plan year which is the nearest intersection of higher-order roadways. Based on materials contained in the 2035 Eugene Transportation System Plan (TSP), both Hilliard Lane and the adjacent River Road corridor are anticipated to operate with link volume-to-capacity ratios of less than 0.80 in the 2035 plan year and meet agency mobility targets. 7. The transportation system impacts resulting from the proposed zone change from R-1 to PL will not change the functional classification of an existing or planned transportation facility, will not change the standards implementing a functional classification system, and will not result in volume-to- capacity ratios exceeding agency mobility targets. As such, OAR 660-012-0060 requirements are satisfied without any additional transportation analysis. 8. The proposed zone change from R-1 to PL does not trigger the need for a TIA per Eugene Code Section 9.8670. Further, if at any time the School District plans to increase student capacity resulting in the need for a TIA, the City Planning Division will be notified and an evaluation per Eugene Code will be provided.
