PAGE 9 CITY OF SOUTH BEND MARKET DISTRICT IMPROVEMENT PROJECT TOPOGRAPHIC SURVEY The topographic survey serves as the foundation for the project conceptual design alternates, which is why we will get started on this immediately following project award and notice to proceed. Our survey team already has this project earmarked in their schedule for Q3 2023. Because the project limits cover a large area and we understand the priority the City has set, our team will perform full topographic survey for projects 01 to 08, east of the St. Joseph River, right out of the gate. COST SAVINGS IDEA For projects 09 to 13, which are located west of the St. Joseph River, we will utilize available GIS and public LiDAR data to perform the preliminary planning study. We have successfully provided surveying services on numerous projects, ranging from small intersection improvement projects to large urban highway projects. We will use our talented survey staff to incorporate all available GIS information and aerial imagery supplemented with LiDAR data and field survey where needed. By using multiple survey delivery methods we will be able to provide South Bend with a solid foundation on which to develop this project and get the most value out of the project funds. Our design will take full advantage of the topographic survey options previously outlined to ensure that when this project is transitioned from a planning project to full design, re-work will be minimized, thus saving South Bend both time and unnecessary cost. TRAFFIC STUDY Our traffic team is intimately familiar with the City of South Bend’s traffic signal system, roadway network and current operational desires. Our preliminary review of the crash data has helped define the direction of the proposed project. The proposed realignment of the streets leading to/from the Eddy Street Bridge is anticipated to improve safety in this area as existing conditions resembling those typical of a freeway will be avoided with the removal of the existing ramps. This change will remove the existing conflict points in areas that are prone to higher operating speeds. The proposed realignment of the roadway network in the vicinity of the bridge is anticipated to improve access and mobility while having a traffic calming effect on the local streets. Our analysis would include traffic data collection such as intersection turning movement counts and origin-destination (O-D) data. During the Smart Streets Traffic Analysis that our team completed, cell phone data was utilized to provide detailed and accurate O-D data to assist with the redistribution of traffic throughout the City’s roadway network. A similar, but more refined approach would be necessary for the proposed traffic calming and elimination of certain movements. In addition, our team would work closely with the Michiana Area Council of Governments (MACOG), to review and refine the travel demand model to account for growth (creation of newer mixed-use urban areas) and the impacts to the roadway network as a result of the interchange removal. We will work with the City to determine the proper safeguards for pedestrians, bicyclists and micro-mobility services. Special attention will be paid to ADA accommodations throughout the design while coordinating with the road design and environmental teams. Our traffic team is experienced with alternative intersection types (such as roundabouts, median u-turn, quadrant roadway, displaced left-turn, continuous green-T), and determining which situations these intersections are most beneficial to operations while providing traffic calming effects. ROADWAY CONCEPTUAL DESIGNS We will start our conceptual design by taking all the information from the traffic study and coordination with MACOG, along with valuable input gathered during the charrette held at the University of Notre Dame and documented by the School of Architecture to advance the roadway network concept from the roadway network shown on the previous page. We will develop multiple roadway typical section alternates that include varying travel
