SCOPE OF WORK(continued) alternatives will be identified based on the results of the active transportation demand map,identified gaps and needs as well as the development of other modal alternatives. The consultant will analyze the performance of up to 10 active transportation alternatives using spatial analysis. The active transportation alternatives to be evaluated will be identified by determining which active transportation alternatives meet the need of this project. It is likely that more than 10 alternatives will be identified during this process but many of these may be projects that are best evaluated outside of the US 2/1-5 Interchange Planning Study because they do not specifically meet the need.This information will support the Screening in Task 05-04.The consultant will analyze both pedestrian level of service(PLOS)and bicycle level of traffic stress(BLTS) of the alternatives to establish the relative performance of different active transportation alternatives.The BLTS analysis will be completed for roadway segments.The PLOS will be completed for both roadway segments and intersections. Both the PLOS and BLTS will report level of service on a 4-point scale,with 1 indicating low stress facilities and a 4 indicating high stress facilities. Assumptions • Up to 10 active transportation alternatives will be evaluated in the first level screening • Up to 5 active transportation alternatives will be evaluated in the second level screening • Only conceptual level engineering with be completed Deliverables • Draft and Final Active Transportation section of the final report Subtask 5-02—Design Approach The Consultant will develop planning study roadway layouts in support of the Alternatives Development and Evaluation. The planning study roadway layouts will take into consideration horizontal and vertical roadway geometry, roadside safety, maintenance of traffic, and construction phasing,and will provide an appropriate level of detail ,to establish approximate environmental impacts and support an opinion of cost. Planning study roadway layouts will include edge to edge roadway limits over GIS maps to illustrate level of impact to social,natural environment, and existing right of way. Other planning level design considerations will include stormwater, utility,and structural design elements. Stormwater design considerations may include the identification of drainage needs in accordance with the appropriate standards. Drainage needs and stormwater management concepts,which may include flow control and water quality treatment, will be evaluated at a planning level for up to two(2)alternatives in support of the Preferred Alternative Selection Screening to support estimating overall alternative impacts and costs, including potential right-of-way acquisitions that may be required for stormwater facilities. The Consultant will analyze existing utility information gathered in Task 3 and identify any major potential utility relocations. Cost responsibility will be established, and the potential utility relocations will be evaluated for cost impacts to the project and considered in developing the opinion of cost.
