Hilliard Lane (River Road Elementary School) Property - Eugene, Oregon <br />C&A Project Number 20211201.00 <br />June 23, 2022, Revised August 12, 2022 <br />Page 4 <br />4. SUMMARY <br />The following conclusions and recommendations are made based on the materials contained in this <br />analysis. <br />The subject property, described as tax lot 2000 on Lane County Assessor's Map 17-04-24-23, is <br />addressed 148 W Hilliard Lane in Eugene. The property is 4,356 square feet in size and is currently <br />developed with a single-family residence that is used by the Eugene School District 4J (4J) to provide <br />student support services for the adjacent River Road/Camino del Rio Elementary School. <br />2. The property has been recently annexed into the City of Eugene. To formally establish student support <br />programs at the existing school, 4.1 is proposing a property zone change from Low Density Residential <br />(R-1) to Public Land (PL). <br />3. The subject land use action does not contemplate specific property development. Rather, it <br />contemplates a zone change and a traffic impact analysis study is necessary to address Transportation <br />Planning Rule (TPR) criteria outlined in Oregon Administrative Rule (OAR) 660 012-0060. <br />4. The proposed land use actions do not include a specific development application. As such, this analysis <br />evaluates impacts resulting from reasonable worst-case development scenarios in the current and <br />proposed zone designations. Specifically, this analysis assumes a 1,500 square-foot daycare facility in <br />the proposed PL zone and a 3 attached residential dwelling units (a triplex) in the current R-1 zone. <br />5. Reasonable worst-case property development in the proposed PL zone designation generates an <br />additional 49 daily and 15 PM peak hour trips over the current R-1 zone designation. <br />6. The potential development trip generation increase of 15 PM peak hourtrips is considered de minimus <br />as it represents less than 5% of the traffic entering the River Road/Hilliard Lane intersection in the <br />2035 plan year which is the nearest intersection of higher-order roadways. Based on materials <br />contained in the 2035 Eugene Transportation System Plan (TSP), both Hilliard Lane and the adjacent <br />River Road corridor are anticipated to operate with link volume-to-capacity ratios less than 0.80 in the <br />2035 plan year and meet agency mobility targets. <br />7. The proposed zone change from R-1 to PL will not result in a trip generation increase that significantly <br />affects any existing or planned transportation facilities. As such, OAR 660-012-0060 requirements are <br />satisfied without any additional transportation analysis. <br />8. The proposed zone change from R-1 to PL does not trigger the need for a TIA per Eugene Code Section <br />9.8670. Further, if at any time the School District plans to increase student capacity resulting in the <br />need for a TIA, the City Planning Division will be notified and an evaluation per Eugene Code will be <br />provided. <br />Sincerely, <br />Christopher M.
