Zoning File #1093 January 7, 1987 Page 4 of 4 Of the 4 access sites reviewed, Tanglewood's existing access is the poorest, in that looking eastward, sight distance barely meets the absolute safety minimum for the 55-MPFI road, and does not meet the 850' applicable standard. Any of the other locations would be very acceptable in both directions. Tanglewood is not extremely unsafe under the existing traffic conditions on County Road 6, but would potentially be unsafe at some undefined level above the existing 4,000 vehicle per day traffic level. on County Road 6. According to Zetterstrom, the Hennepin County Department of Transportation would generaly start to look at limiting access when County Road 6 reached 5,000 vehicles per day. Tanglewood access relocation further east, within the Knoll Manor plat provides an access location for all Tanglewood and Knoll Manor residences that will meet the accepted safety standards. Furthermore, staff contends that the revised access will not increase extraneous traffic on Tanglewood Road but may decrease it, by providing a logical turn -around point where Knoll Manor intersects it (this is assuming the extraneous traffic consists of people who are lost, riot sight- seers). Also, Tanglewood will be a curvilinear road rather than straight, again a factor in giving the road exclusivity and a greater degree of privacy. Knoll Manor residents will have no need to travel past their own road intersection, hence traffic would not be likely to increase. The Knoll Manor and Tanglewood residents have the ability to post this as a private road. It would seem wise from a planning standpoint to close the existing relatively lcsc safe Tanglewood access given that better alternatives exist, however, because this is a private road, the Hennepin County Highway Department wili not force the change to occur until such time that traffic levels on County Road 6 increase to a point where the Tanglewood access is a hazard. If the City wants to force the change to occur now, the County has stated they wil L support the City's position. Staff Recommendation: While there may be an issue as to whether the City his the complete authority require the Tanglewood homeowners or the Underhill. property ers to accept the change ;n access location, from a planning persF tive, staff recommends Alternative 1 be adopted as the required access connection if Council feels it is appropriate to make the access change at this time with the currently proposed developement. If Counci 1 determines that no change is warranted at this time, Option 4 with the out lot for future access relocation would be appropriate. under this option, we would recommend that a condition of subdivision approval be the preservation of the City's right to specifically assess the 4 Knoll Manor lots for any future access changes that are required. Given a suitable resolution of the access staff world recommend preliminary approval of this subdivisior, w_t` a formal resolution of preliminary subdivision approval to be presented at your next meeting.
