City Staff has utilized the services of Bolton and Menk Consulting Engineers to prepare this report. Traffic generated from this development will primarily utilize the TH 47 con'idor. Major intersections along this corridor were analyzed including 160th Lane, Alpine Drive, Snnwood Drive, CSAH 5/Xkimo Street, and CR 116. With the exception 0fCR 116 these intersections are currently operating at an acceptable level of service of D or better. In the afternoon peak period the intersection of CR 116 is currently operating at an F level of service and delay will increase as a result of this development. An upgrade to the level of service at this intersection will require geometric improvement of these highways. Stop signs are to be placed on the entrances onto TH 47, and it is recommended that left turn and right through lanes be added to the TI:[ intersection of 160th Lane at TH 47. Streets and Access: The sketch plan proposes one new access to Highway 47, at 160th Ln NW and to co,meet to 162nd Ave NW. Lithium Street has been proposed as a stub street to the north; The tern porary cul-de-sac proposed will need to accomadate snow storage within the public right of way. ~l'he plans for this street need to be revised. MnDOT has indicated that the proposed access onto TH 47 is Consistent'with 'their adc~s sp~cifi~ ~,fi[d~li-n~s.' 'The ~n-s~alI~/ff0h 6fleft-~ ~ " lanes £or both northbound and southbound TH 47 has been incorporated into the construction requirements as well the construction of a northbound right turn lane into the proposed subdivision. In. a June 15, 2005 plat review letter MnDOT has indicated that residential land use may not be compatible with highway impacts, noting potential noise complaints. MnDOT policy prohibits thc expenditure of highway funds for noise mitigation measures. A combination of berming and landscaping has been provided as a buffer to the highway. Sidewalks: City policy requires the installation of sidewalks along one side of all non cul-de-sac public streets in single-family developments. The final plans submitted are consistent with this policy.
