1 <br />EC 9.8320(5): The PUD provides safe and adequate transportation systems through compliance <br />with the following: <br />(a) EC 9.6800 through EC 9.6875 Standards for Streets, Alleys, and Other Public Ways <br />(not subject to modifications set forth in subsection (11) below). <br />Oakleigh Lane abuts the west half of the north boundary of the subject property. The applicant's <br />survey shows that the portion of Oakleigh Lane abutting the subject property has 20 feet of right-of- <br />way width, with approximately 19 feet of pavement width that partially overlaps the north boundary <br />of the subject property, outside the public right-of-way. Instead of dedicating additional right-of-way <br />to widen the roadway, the applicant proposes a 20-foot special setback from the north property <br />boundary (which coincides with the official right-of-way centerline). <br />East of the roadway is a row of cedar trees, which are primarily on adjacent lands to the north. Hence, <br />extending Oakleigh Lane to the east would necessitate right-of-way dedication from the northerly <br />property owner and, potentially removal of the cedar trees. Instead of extending Oakleigh Lane to the <br />east, the applicant submitted a street connectivity study prepared by Access Engineering, LLC, which <br />shows how the adjacent lands to the north could be further divided with flag lot access off the existing <br />20 feet of right-of-way, with just an additional five-foot right-of-way dedication (as multiple flag lots <br />require 25 feet of street frontage). (Refer to Attachment D-5.) <br />Referral comments from Public Works confirm that the proposed street layout provides a safe and <br />adequate transportation system, subject to additional findings and conditions for compliance with EC <br />9.6805 through EC 9.6875 Street Standards, as provided below. With regard to EC 9.6805 Dedication <br />of Public Ways, Public Works staff recommends right-of-way dedication west of the development's <br />driveway, so that the abutting street, Oakleigh Lane, will comply with EC 9.6870 Street Width. Public <br />Works staff also recommends right-of-way dedication, east of the driveway, to enable the <br />construction of a hammerhead turnaround, consistent with EC 9.6820 Cul-de-Sacs and Turnarounds. <br />Public Works staff confirms that no additional right-of-way or special setback is required based on the <br />acceptability of the applicant's street connectivity study; Public Works staff recommends the <br />exception to EC 9.6815 Street Connectivity be approved. Details of these findings, with the <br />recommended conditions of approval, are provided below. <br />Pursuant to EC 9.6850 Dedication of Public Ways, as a condition of any development, the City may <br />require dedication of public ways for bicycle and/or pedestrian use as well as for streets and alleys, <br />provided the City makes findings to demonstrate consistency with constitutional requirements. The <br />public ways for streets to be dedicated to the public by the applicant shall conform to the adopted <br />right-of-way map and EC Table 9.6870. EC 9.6870 Street Width confirms that the required right-of- <br />way width for Oakleigh Lane is 45 feet, based on the street functioning as a Low-Volume Residential <br />Street. Public Works staff confirms that there are currently 25 residential tax lots along Oakleigh Lane, <br />and with the addition of 29 dwelling units proposed by the subject development, the Average Daily <br />Traffic (ADT) would be greater than 500 trips per day, which is within the expected 250-750 ADT range <br />for low-volume streets. <br />The existing right-of-way width abutting the subject property is 20 feet, which was dedicated by <br />properties to the north, per the Plat of Oakleigh in 1927.
