Co-housing Development <br />I am writing this letter in response to the traffic issues raised by Mr. Simon Trautman <br />concerning the safety of Oakleigh Lane and in accordance with the open-record sequence <br />specified at the Eugene Planning Commission meeting on Monday, August 17, 2015. <br />This letter is a supplement to my Street Connectivity Study dated August 6, 2013, and <br />my comments from September 27, 2013, and October 15, 2013. Please accept this letter <br />and include the same in the record of these proceedings. <br />Oakleigh Lane is a dead-end local street that runs approximately 1000 feet east from the <br />centerline of River Road. It is one of four consecutive streets that terminate at City <br />parkland on the west bank of the Willamette River. The street has an oil-mat surface of <br />approximately 20-feet in width, with no curbs and with intermittent gravel shoulders <br />along both sides of the street that permits parking in some areas. As is common with <br />other low-volume residential streets in Eugene, Oakleigh Lane allows unsegregated <br />vehicular, pedestrian and bicycle access. <br />1. Impacts are Not Hazards <br />Transportation Engineering <br />7Yafflo Design <br />Trip Generation <br />Access Management <br />Traffic Counts <br />Street Lighting <br />Comments submitted to the Planning Commission confuse traffic impacts with traffic <br />hazards. No one disputes that the Oakleigh Meadow Co-Housing development will have <br />traffic impacts. The development will generate some additional trips on Oakleigh Lane. <br />However, additional trips do not mean an increased hazard. The Oakleigh Meadow <br />development includes 28 dwelling units. The Ninth Edition of the Institute of <br />Transportation Trip Generation Manual classifies this type of development as a <br />"residential condominium/townhouse." The traffic impacts from the proposal would be <br />just 168 average daily trips. <br />As a low-volume residential street, Oakleigh Lane can safely accommodate between 250 <br />and 750 average daily trips. Combining traffic from Oakleigh Meadow with the 21 <br />existing single-family homes on Oakleigh Lane, which are equivalent to 210 daily trips, <br />the total would be 378 daily trips, well within the range for a low-volume residential <br />street. <br />City Public Works comments do not identify any traffic hazard on Oakleigh Lane. Staff <br />references to traffic impacts under its dedication findings for the halfstreet dedication <br />and 13' foot wide public accessway on the OMC property frontage are common <br />constitutional findings in support of the dedication. Since the PUD is the last opportunity <br />for the City to obtain right-of-way from the OMC property, public works staff looked to <br />the projected traffic impacts from the PUD to establish the rough proportionality of the <br />property taken and the traffic impacts. <br />243 <br />
