3 <br />1 Per Table 9.6870 the minimum right-of-way width for low-volume <br />2 streets is 45.' The existing right-of-way in Oakleigh Lane is 20', <br />3 which was dedicated by the properties to the north per the Plat of <br />4 Oakleigh in 1927. Staff notes that the southerly margin of this 1927 <br />5 dedication forms the centerline of Oakleigh Lane and that any <br />6 additional dedications would necessarily be based on this centerline. <br />7 <br />8 Based on the right right-of-way requirement of 45' and the existing <br />9 right-of-way width (which as noted, is located entirely north of the <br />10 centerline), an additional 22.5' south of the centerline is required. <br />11 This dedication would satisfy the right-of-way requirement for the <br />12 properties south of centerline, with the remainder of the 45' right-of- <br />13 way being required from properties on the north side of the centerline. <br />14 <br />15 However, per the findings at EC 9.6815, the applicant qualified for an <br />16 exception to the street connectivity requirements. The alternate street <br />17 study identified the amount of right-of-way necessary to construct an <br />18 emergency vehicle turnaround beyond the end of the existing <br />19 Oakleigh Lane, which would also provide the necessary frontage for <br />20 flag lot development of TL 200. The proposed turnaround would <br />21 straddle the common property line between the proposed development <br />22 and TL 200. The portion of the right-of-way that is located within the <br />23 proposed development is identified on Fig. 1 of the alternative street <br />24 study as being a strip that is 9' wide x 116.5' long. (Staff notes that <br />25 the length should be 117' to allow an extra 6" for constructability <br />26 issues). <br />27 <br />28 Staff notes that while the applicant's proposal is sufficient to <br />29 accommodate the turnaround which would be necessary to separate <br />30 pedestrians from vehicles and provide a safe public walking surface <br />31 for the residents of the proposed development. The amount of right- <br />32 of-way necessary to allow for the construction of the proposed <br />33 turnaround and adjacent sidewalk would be 33' or 13' on the south <br />34 side of the existing centerline, which as previously noted is co- <br />35 incident with the property line. These dimensions assume a 21' wide <br />36 paved surface that is shown on the tentative plan as being located 6' <br />37 south of the existing northerly right-of-way line, a 6" curb, a 5' <br />38 sidewalk and a 6" area adjacent to the sidewalk for construction and <br />39 maintenance purposes. <br />40 <br />41 Staff further notes that as a result of the approved street connectivity <br />42 exception, Oakleigh Lane, east of the development's entry drive aisle <br />
