FROM: Charles Folch, City Engineer I DATE: January 8, 1992 I -13 c t Y I SUBJ: Authorize Preparation of Supplement to the Feasibility Study for the West 78th Street Detachment, Powers Bouelvard (C.S.A.H. 17) Project No. 87 -2 1 A little over a year ago, the consulting engineering firm of I Strgar- Roscoe - Fausch was commissioned to study the existing downtown transportation system and was to make recommendations for needed improvements both for the near term and into the future. This study and report has since been completed and has been I formally presented to the City Council, HRA and Planning Commission. The immediate recommended improvements for West 78th Street effect both the existing segment between Great Plains I Boulevard and Kerber Boulevard and also the design of the proposed West 78th Street detachment project between Kerber Boulevard and Powers Boulevard (County Road 17). Given their established I background in performing this downtown study and level of expertise in the transportation field, Strgar - Roscoe- Fausch has been selected to proceed with the implementation of the recommended improvements. I As the project number 87 -2 implies, the original feasibility study for the West 78th Street Detachment project was completed in July of 1987. Since that time, the project has encountered numerous I delays and obstacles surrounding the development proposals for properties adjacent to the roadway.' As such, a Supplemental Report No. 1 for the original feasibility study was completed in July of I 1988. Since no construction has begun on this project within one year of the last public hearing State Statute 429 for public improvement I project utilizing special assessments as a portion of the funding mechanism for the project requires that the City Council reinitiate the project process by authorizing the preparation of another 1 feasibility study or supplemental amendment to the original study ts, PRINTED ON RECYCLED PAPER 1 Mr. Don Ashworth January 8, 1992 Page 2 and hold another public hearing to update the scope and costs associated with the project. ' Strgar- Roscoe - Fausch had provided the City with a proposed scope of services and fee schedule for administrating the project from the 1 feasibility study amendment through construction (see attached). It should also be noted that the City had previously committed itself to upgrade County Road 17 north of Trunk Highway 5 to the detachment intersection in conjunction with MnDOT's plans for the intersection improvement with Trunk Highway 5 which proposed to relocate the existing West 78th Street /County Road 17 intersection to the new detachment area approximately 350 feet to the north. ' This work is scheduled to take place in the late spring early or summer of 1992. ' In order to properly sequence MnDOT's construction at the intersection with County Road 17, it will be necessary for the City to proceed with the improvement project process for the construction of the West 78th Street Detachment such that bids ' could be taken and construction initiated as soon as possible this spring. ' It is therefore recommended that the City Council authorize the preparation of the Supplemental Report No. 2 to the feasibility study for the West 78th Street Detachment /Powers Boulevard (CSAH 17), Project No. 87 -2 to address the needed improvements and associated costs as recommended in the recently completed downtown traffic study that the consulting engineering firm of Strgar- Roscoe- Fausch be assigned to the project.
