To do this the City Council must approve an amendment to the Transportation Chapter of the Comprehensive Plan. The City 1 Council, at the October 24 , 1988, meeting will be making a deci- sion between Option 2 and 2A for the proposed realignment of TH 101 and will also be adopting an official map delineating the 1 alternative chosen. State statute requires that the Comprehensive Plan must be amended to include the proposed street corridor ( "thoroughfare plan" ) prior to the adoption of the offi- cial map. Attachment #1 and #2 are proposed text amendments to the Transportation Chapter of the Comprehensive Plan. The texts 1 refer to both the 2 and 2A alternatives . The proposed text will be replacing the paragraph pertaining to STH 101 on Page t-36 and deleting pages t-37 through t-43 (Attachment #2) . 1 RECOMMENDATION Planning staff recommends the City Council adopt the following 1 motion: - "The City Council approves of the Comprehensive Plan text amend- , ment #88-6 as presented in Attachment #1 or #2 to the TH 101/TH 5 intersection has been determined by the City Council. " ATTACHMENTS 1 1 . & 2 . Proposed text. 3 . Existing Comprehensive Plan Text. . I NI ' r ALTERNATIVE 2 T. H. 101 (Realignment) - The Year 2005 Transportation and Land Use Study was authorized by the HRA at the conclusion of the downtown community and developer forums in the summer and fall of 1985. The ' purpose of the Study was to develop a land use and circulation plan that provides for linkages between the downtown and the remainder of the community as well as to evaluate the impacts of proposed TH 212 on the transportation system. The transportation plan advocates the relocation of 101 traffic away from downtown, thereby separating through traffic from local business traffic. The conceptual alignment of TH 101 is shown on the next page. The realignment of TH 101 provides three distinct benefits. It preserves an adequate level of service at all TH 5 intersections. Secondly, it improves 1 the north-south continuity of TH 101. Finally, it alleviates the impacts of through traffic on TH 101 on the downtown area. It is expected that the Dakota Avenue intersection will operate at a level of service D, the Great Plains Boulevard intersection at a level of service E, and the Market Boulevard intersection at a level of service C. Key elements y of the conceptual TH 101 layout include the following: Use of the present Dakota Avenue intersection for the north leg of TH 101 and including the northerly relocation of West 78th Street to provide sufficient stacking distance between TH 5 and West 78th Street. This will include a single railroad crossing with the Soo Line Railroad tracks aligned through the intersection of TH 101 and West 78th Street. ' A joint highway� g ay section with TH 5 and TH 101 sharing a common section ' between Dakota Avenue and existing Great Plains Boulevard. Volumes on the joint section will exceed 40,000 ADT in year 2005. A four-way intersection of TH 5/101 at Great Plains Boulevard and the continued use of Great Plains Boulevard south of TH 5 as TH 101. Great Plains Boulevard will have to be realigned in the near term to bring it up to accepted engineering standards. ' The purposed new alignment exists at the present time only in concept form. Additional refinement of the design involving MnDOT Staff will be necessary to ensure effective, safe traffic operation. 11111111111T1 1111111111111111r• - . _ s, , ! • '3 ..'...'2 ,27.2.--t—'2 2....i...}.4:L.....,..,/\.,\„:„..Y. 3......_SANTA .A..C.

H. 101 (Realignment) - The Year 2005 Transportation and Land Use Study was authorized by the HRA at the conclusion of the downtown community and developer forums in the summer and fall of 1985. The ' purpose of the Study was to develop a land use and circulation plan that provides for linkages between the downtown and the remainder of the community as well as to evaluate the impacts of proposed TH 212 on the ' transportation system. The transportation plan advocates the relocation of 101 traffic away from downtown, thereby separating through traffic from local business traffic. The conceptual alignment of TH 101 is shown on the next page. The realignment of TH 101 provides three distinct benefits. It preserves an adequate level of service at all TH 5 intersections. Secondly, it improves the north-south continuity of TH 101. Finally, it alleviates the impacts of through traffic on TH 101 on the downtown area. It is expected that the Dakota Avenue, Great Plains Boulevard and Market Boulevard intersections will all operate at a level of service D in 2005. Key elements of the conceptual TH 101 layout include the following: Use of the present Dakota Avenue intersection for the north leg of TH 101 and including the northerly relocation of West 78th Street to provide sufficient stacking distance between TH 5 and West 78th Street. This will include a single railroad crossing with the Soo Line Railroad tracks aligned through the intersection of TH 101 and West 78th Street. A joint highway section with TI-I 5 and TH 101 sharing a common section between Dakota Avenue and Market Boulevard. Volumes on the joint section will exceed 40,000 ADT in year 2005. A four-way intersection of TH 5/101 at Great Plains lams Boulevard with a local connection to Lake Drive East. ' A four-way intersection of TH 5/101 at Market Boulevard and the relocation of 101 traffic to Market Boulevard. This layout will include an entirely new south TH 101 leg to the south Ward property line. The purposed new alignment exists at the present time only in concept form. Additional refinement of the design involving MnDOT Staff will be necessary to ensure effective, safe traffic operation. 1 II, . . . t-36 C, Galpin Boulevard (C . S .A . H . 117) : In the future, Galpin Boulevard will serve primarily as a Chanhassen collector, carrying traffic I out of the northern neighborhoods into the downtown area or onto Highway 5 . ' I Lake Lucy Road : Prior to 1990 , Lake Lucy Road should be upgraded to adequately perform as a collector street for development in the northern section of the City . The major streets plan depicts Lake Lucy Road as being extended westward between Galpin Boulevard and S . T. H. 41 . This extension would serve both residential development in the area and the Lake IMinnewashta Regional Park which is presently being acquired . Downtown Area : The major streets plan depicts a CBD circulation system which is consistent with the Chanhassen Downtown Redevelopment II Plan . This plan calls for the removal of existing 78th Street and the construction of a ring road around the commercial area . S .T . H. 101 : Trunk Highway 101 has been classified by MnDOT as I ` , a temporary state highway which essentially means that only surface maintenance will be carried out and no other state funded improvements will occur. North df Highway 5 , 101 is 1 shown as being extended directly to the south to help alleviate unnecessary traffic congestion in the CBD area . South of 5 , proposed improvements include the straightening of the curves Mil on the east side of Lake Susan , the eastern realignment of 101 north of Lyman Boulevard , and the combination of 101 and Bluff Creek Drive into a common access onto Highway 212 . I Dell Road : The proposed alignment of Dell Road is on the Chanhassen-Eden Prairie line in the portion of Chanhassen which lies within Hennepin County. The Dell Road alignment which I is shown in the Eden Prairie Comprehensive Plan will carry traffic from Eden Prairie ' s northern residential neighborhoods I northward to the Crosstown extension and southbound to Valley View and Highway 5. Dell Road is important to Chanhassen as a I collector because the north and south Highway 5 frontage roads have been designed and constructed in such a manner as to allow a future connection to Dell Road . Because of the importance of this I route to both cities , Chanhassen and Eden Prairie should coordinate all future developments and road improvements in the Dell Road area . IOther Routes : The major streets plan shows other collector streets which are all continuations of their present status . As development proposals are reviewed in land areas adjacent to I these routes , the City should strive to uphold access limitations and other design parameters which are essential if collectors are to handle traffic volumes effeciently.
