being located 6' south of the existing northerly right-of-way line, a 6" curb, a 5' sidewalk and a <br />6" area adjacent to the sidewalk for construction and maintenance purposes. <br />Staff further notes that as a result oft he approved street connectivity exception, Oakleigh Lane, <br />east of the development's entry drive aisle will effectively function as a cul-de-sac, with traffic <br />volumes falling well below the 250 ADT threshold for low-volume streets. Therefore, the <br />nominal right-of-way width beyond the entry drive aisle of the proposed development will be <br />reduced to 33' (13' south of centerline), consistent with the approved street connectivity <br />exception. <br />EC 9.6875 Private Street Design Standards <br />These standards do not apply because no private streets are proposed or required. <br />(5)(c) The provisions of the Traffic Impact Analysis Review of EC 9.8650 through 9.8680 <br />where applicable. <br />The development and existing street system do not warrant review under this criterion, <br />pursuant to the applicability criteria at EC 9.8670. The applicant notes that the development <br />will generate roughly 15 PM peak hour trips, which is well below the 100 trip threshold of these <br />standards. Further, staff has no concerns related to traffic safety issues or poor service levels <br />which will. result from this development. The traffic generated by this site will not result in <br />routine heavy truck traffic. <br />(6) The PUD will not be a significant risk to public health and safety, including but not limited <br />to soil erosion, slope failure, stormwater or flood hazard, or an impediment to emergency <br />response. <br />Due to the size of the development, an erosion prevention permit will be required prior to any <br />ground-disturbing activities. <br />Based on the recommendations made by the Geotechnical Engineer, the site appears to be <br />geologically stable and adequate for development. Per the Level 3 Geotechnical report <br />submitted with the application, the Geotechnical Engineer recommended construction <br />techniques consistent with industry standards, none of which indicate the existence of unsafe <br />sub-surface conditions or soil conditions requiring extensive construction to mitigate any <br />significant geological hazards or soil drainage issues. <br />With regard to risk of stormwater or flood hazard, per the findings at EC 9.8320(11)(c), any <br />structures placed within the identified flood hazard area will be required to comply with EC <br />9.6707 through EC 9.6709. The development itself will not result in unreasonable risk offlood <br />per the stormwater management evaluation at EC 9.8320(11)0). <br />_PDT13-01 Oakleigh Cohousing <br />Page 11 of 22 <br />1265 <br />
