1- j 15-3763 July 16,2015 Page 5 of B such a cox�necting corridor. Because Kintyre Lane is a private road which will soon become completely under control of a homeowners association rather than guided by the developer of Kintyre, the City Attorney has been working with the developer of Kintyre and Bollis' attorney to establish easement rights and maintenance responsibilities for the extension of Kintyre Lane to serve this proposed developmen� Those discussions are still underway as of this writing; however, it appears that some agreement will be forthcom��in the neaz future. The preliminary plat depicts a proposed road corridor width of 50 feet which meets code. The standard minimum paved width for a road serving more than 7 units would be 28', and this would be a rural section (shoulders and ditches) except where curbing is necessary to manage stormwater. The plans indicate a 30' street width (back to back of surmountable curb) which apparently is necessaty to direct road runoff to the pmposed stormwater pond. For engineering discussion is the fact that Kintyre Lane is only 2b' wide (back of curb to back of curb) as it was only designed to serve 6 homes and meets code for 6 homes. With adding 7 more homes using the road, existing Kintyre Lane will become substandard in width... Road Improvements andlor Easements Needed The City will require a Road, Drainage and Utilities Easement over the private road. Standard perimeter drainage and utility easements wil� be required along all property boundaries in the plat as well as Conservation and Flowage Easements over all delineated wetlands and drainageways. Whether existing Kintyre Lane should be widened may be worthy of discussion, but to do so would be expensive and likely meet with significant resistance from the existing neighbarhood and have significant cost ramifications. At the sketch plan review it was noted by one Council member that the existing cul�e-sac perhaps should be removed. There are likely pros and cons to daing so, and it would require cooperation and acceptance by the existing Kintyre neighbors. Park/Trail Easement/Fees or Ded'rcation Needed Although the Pazk Commission has nat reviewed the proposed piat, it is anticipated that no land for a public park is required, in part due to the remoteness of the deueloping area from public roads. The C�VIP indicates that a future trail is proposed along Stubbs Bay Road, connecting from a co�aceptual trail along the south side af the Burlington Northern raalroad corridor down to the shore of Stubbs Bay. Whether this trail will ever be completed is unknown; a 14' easement along the west boundary for future trail purposes should be considered. Additionally, as 6 new building sites are being proposed, payment of the standard Park Dedication fee for 6 new building lots would be appropriate; the current fee is $5,550 per lot or a total of 533,300. Stormwater and Drainage Improvements Creation of a new private road requires stormwater stormwater management measures, and theose proposed include a stormwater pond located within Lots 2 & 3 as well as road curbing and stormsewer piping to convey runoff to the pond. Ponding ateas will require the establishment of easements and the ponding areas up to the outlet level aze not creditable as dry buildable area. The properly will be subject to the Stormwater and Drainage Trunk Fee, resulting in a fee of 6 lots @$7680/1Qt=$46,080.
