(5) Routing Lake Shore Drive traffic to Cantrell Street, ' (6) Redesignating Rt. 105 to Eldorado Street (Rt. 36) and Rt. 51. In addition, the consultant is required to study a minimum of two add.itional options beyond those six identified. Quite frequently, two or more alternatives may be combined to evaluate their effectiveness. Bucher,Willis&Ratli.ff will assess and analyze a maximum of ten alternatives on their traffic impacts. Each of the alternatives will require approval by the City prior to major investigation. These alternatives will be tested on various development timing schedules as previously identified in Task 3. The evaluation criteria will be unbiased, consistent, including evaluaHon of intersection and nodal level-of- service, traffic safety improvements,general community impacts, environmental impact, and preliminary construction cost and benefit/cost ratios as outlined in the following tasks. This task will primarily identify transportation unprovement alternatives based on future needs. Capacity analyses of proposed alternatives will occur with various types of roadway cross sections. Basic cost estimates will be developed for each improvement alternatives for comparison. TASK 5 - SOCIO-ECONOMIC/LEGAL CONSTRAINT REVIEW As a part of the alternative comparison,it is important to not only evaluate the technical merit,but also review the impact on less quantifiable issues such as the change in quality of life, potential economic impact due to change of access, and overall socio-economic issues resulting from route relocaHon and alteration of the neighborhood. Other legal issues,such as the restriction or removal of existing access, condemnation of certain right- of-way acquisitions, zoning and street classification, as well as any legal constraints and financial costs, if any, to the City that may occur from the Illinois Department of Transportation,will be reviewed as a part of the corridor relocation alternative evaluation process. Recognizing the fact that it will be difficult to quantify some of the intangible factors for comparison, the consultant will evaluate the relative constraints on two basis: comparing the merit of all pertinent factors on a pre-determined relativity scale and on a preliminary mitigation cost. We have learned from our past experience that the comparison of mitigation cost will be particularly effective if it is supported by sound and uniform cost basis. Legal constraints are difficult to compare on a quantifiable scale and will have to be identified and reviewed in a cursory fashion. Nevertheless, the consultant will present to the City important concerns on any relocation alternatives prior to proceeding further with the analysis. TASK 6- IDENTIFICATION OF PRELIMINARY ENVIRONMENTAL CONCERNS This particular task will primarily deal with the physical feature of the environmental issues relating to the potential relocation of Lake Shore Drive. While the project is confined by the budget constraint from exercising a more detailed environmental assessment analysis, it is the intent of the consultant to conduct a cursory review of �o
