Following both public and City Council discussion, it was apparent that there were a few issues that warranted further study and discussions with adjacent property owners, particularly as it related to access control and locations along the proposed roadway. Therefore, the Council acted to continue the public hearing until these issues could be resolved. During the time period that followed the public hearing, staff became aware that Target was ' interested in developing at a site immediately south of the detachment roadway. Due to the potential impacts of a major retail development such as this, staff concluded that the feasibility study could not realistically be completed until Target had officially chosen a site location and submitted conceptual site plans to the City for review. These submittals have since transpired and on September 14, 1992, the Council gave conceptual PUD approval for the Target site plan. During the planning and development process for the Target site, specifically as it relates to the acquisition of the Burdick property and a portion of Charlie James property, a 1 proposal was made to revise the West 78th Street Detachment intersection with County Road 17 approximately 120 feet south. There were a number of issues involved which led to the proposed alignment change. Thus, staff and SRF were charged with the task of investigating the potential impacts. 1 es 1 ��� PRINTED ON RECYCLED PAPER 1 1 Don Ashworth September 23, 1992 ' Page 2 1 From the City's standpoint, the revised alignment provides some advantages in terms of eliminating the reverse curve along the roadway, reducing impacts to the wetland west of County Road 17 when the future extension of the road occurs, and improving the financial negotiating aspects of the land acquisition. During this very limited time period, contact has been made with the Minnesota Department of Transportation and with the Carver County engineer to discuss the revised alignment. Both MnDOT and Carver County have given ' preliminary indications that this revised alignment would be approved with appropriate design considerations on County Road 17 at Trunk Highway 5 and submittal of supporting traffic analysis documentation. 1 A large scale drawing of the proposed West 78th Street Detachment alignment and overall improvements between Great Plains Boulevard and Powers Boulevard (County Road 17) ' will be presented to the Council at Monday night's meeting. The plan proposes to reconstruct West 78th Street along the revised alignment as a four -lane divided urban roadway section with left and right turn lanes. This roadway segment will incorporate turf ' medians and landscaping consistent with the theme east of Market Boulevard. In addition, the northerly segment of Monterey will be realigned to match the Kerber Boulevard intersection. The majority of this improvement project will occur on the segment between Kerber Boulevard and Powers Boulevard (County Road 17); however, the plan also proposes to 1 construct street widening and median nose improvements to the portion of West 78th Street between Kerber Boulevard and Great Plains Boulevard. These improvements would yield a four -lane divided roadway segment between Kerber Boulevard and Laredo Drive and 1 along the westbound segment between Great Plains Boulevard and the entrance to the Riviera parking lot. This plan also shows future widening improvements which could be implemented to the segment between Great Plains Boulevard and Laredo Boulevard at sometime in the future when traffic volumes warrant a four -lane, divided facility. In effect, this is a master plan which would ultimately yield a four -lane divided urban roadway section 1 from Great Plains Boulevard to Powers Boulevard (County Road 17) and still maintain the landscaped median treatments. During the past few months, the City's consultant engineer for the project and central business district downtown traffic study, Strgar- Roscoe - Fausch (SRF), completed a downtown traffic signal analysis and justification report for the primary intersections along West 78th Street between Great Plains Boulevard and Powers Boulevard (County Road 17). At their regular meeting on July 13, 1992, the City Council acted to authorize signals within the downtown area and asked that public informational meetings be held prior to awarding bids for the signals. These public informational meetings were advertised in The Villager and held on August 24 and September 14, 1992. Although public participation at these meetings was very limited, relevant, pertinent information received from downtown business 1 1 1 Don Ashworth 1 September 23, 1992 Page 3 1 representatives, the Public Safety department and the general public have been incorporated into the revised feasibility report and plan for the overall improvements to West 78th Street between Great Plains Boulevard and Powers Boulevard (County Road 17). The plan displays the installation of traffic signals on West 78th Street at the intersections 1 with Great Plains Boulevard, Great Plains Boulevard, Laredo Drive, Market Boulevard, Kerber Boulevard, Powers Boulevard and at the primary access shared by the Target site and Outlot B. These traffic signals are proposed to be interconnected and operated by a master controller unit which could be programmed to efficiently move traffic in and out of the downtown area and control speeds along West 78th Street. It should also be noted that a master control switch is proposed to be installed at the Fire Station to control both the signals at Laredo Drive and Great Plains Boulevard. The switch would turn the signal at Laredo green (stopping West 78th) while simultaneously giving east and south movements 1 a green light by the clock tower. This should allow traffic to clear West 78th Street before the fire truck(s) get to West 78th Street. The project also includes installing remote control units in all police and fire vehicles to activate all signals within the downtown and on Highway 5. Due to time constraints, revised cost schedules and preliminary assessment roll for this overall West 78th Street Improvement Project will not be available prior to packet distribution. I would anticipate that this information could be given to the City Council at the public hearing during the formal presentation of this improvement project. The special assessment methodology for the roadway improvements is proposed to be consistent with that implemented for the previous West 78th Street improvements east of Market Boulevard. At the close of the public hearing, if there are no further, relevant questions or concerns that warrant investigation, it is recommended that the City Council approve the supplemental feasibility report for the revised West 78th Street Detachment Project No. 92- 3, authorize the preparation of project plans and specifications by the consultant Strgar- Roscoe- Fausch and authorize the condemnation of the right -of -way needed for the revised alignment east of Powers i l l - • . . • - - ' s. jms 1 c: Dave Hempel, Sr. Engineering Technician Dennis Eiler, SRF Jim Dvorak, SRF 1 1 1 1 Don Ashworth September 23, 1992 Page 4 Manager's Comments: As noted by the City Engineer, we met with the County Engineer, Roger Gustafson. Although wanting to review Strgar's traffic counts /projections, Mr. Gustafson is prepared to ask the County Board to endorse the revised project plans. Although he did not state that he would deny the project if a right - in/out (for Ryan) or a left - in/out (for James) was included, he was clear in stating that neither of these would be preferred and both' had the potential of increasing traffic accidents for motorists coming off of County Road 17. 1 DWA (9- 24 -92) 1 1 _ 1 1 1 1 1 1 1 1 1 1
