within X mile of the development site and connections to any streets that abut, are adjacentto, or <br />terminate at the development site. EC 9.6815(2)(c)) requires that the proposed development <br />include streets that extend to undeveloped or partially developed land adjacent to the <br />development site in locations that will enable adjoining properties to connect to the proposed <br />development's street system. EC 9.6815(2)(d) requires secondary access for fire and emergency <br />vehicles. <br />To the north, the proposed development is bordered by a 20' right-of-way, i.e., Oakleigh Lane and <br />an undeveloped 1.2 acre vacant lot, i.e., TL 200. The proposed development is also bordered by <br />partially vacant property (TL 10100) and an underdevelopedtract (TL 5600) to the west, parklands <br />to the east and existing residential development to the south. Existing streets within % mile of the <br />proposed development include McClure Lane to the south, which is separated from the <br />development by existing residential development and East Hilliard Lane which is located <br />approximately 370 to the north. Staff notes that there are no existing or topographical constraints . <br />within the adjacent TL200 that would prevent the extension a street connection from Oakleigh <br />Lane to Hilliard Lane, however the existing 20' right-of-way is not adequate to allow f or the <br />extension of a public street into TL 200, therefore additional right-of-way is necessary from the <br />proposed development to ensure extension of Oakleigh Lane and to ensure that future <br />development ofTL 200 will not be precluded. Without the approval of a street connectivity <br />exception, in order to comply with the street connectivity standards, the applicant would need to <br />extend 22.5' feet of right-of-way (i.e.,'/ width south of centerline) to the easterly boundary of the <br />proposed development. However, the applicant is requesting an exception to the requirement to <br />extend Oakleigh Lane based on EC 9.6815 (2)(g)(1), and has submitted a shadow plat (i.e., <br />alternate street plan) showing how TL.200 could be developed with the minimal widening of <br />Oakleigh Lane together with a narrative showing how the alternate street study meets the intent <br />statement of EC 9.6815(1). , <br />Per Figure 1 of the alternate street plan, TL 200 could be developed with 4 Lots, with Lots 1-3 <br />being created as flag lots from the terminus of the public right-of-way, i.e. an emergency vehicle <br />turnaround, and Lot 4 having frontage along the right-of-way. Per Fig. 1, a minimum right-of-way <br />dedication would be 9', however as discussed at EC 9.6870, a right-of-way width of 13' would be <br />necessary to ensure the construction of a public sidewalk adjacent to the south side of the <br />turnaround. Staff confirms that the proposed turnaround would adequately meet the future <br />frontage requirements for development of TL 200. <br />Public Works staff confirms that the proposed development complies with the intent statements <br />of subsection (1) in the following manner. <br />(1) Purpose and Intent. <br />The street connectivity standards of EC 9.6815(2) Street Connectivity Standards are established to <br />PDT 13-01 Oaldeigh Cohousing Page 5 of 22 <br />1259 <br />
