SCOPE OF SERVICES ATTACHMENT A. SCOPE OF SERVICES The City of South Bend is anticipating the construction of three (3) development projects within the East Race Area; the "Three Twenty at the Cascade", the Commerce Center expansion, and the Seitz Park Improvements. The East Race Area is defined as the property surrounded by the St. Joseph River and the East Race Waterway. The City is concerned that the existing sanitary sewer system within the East Race Area may not have the capacity to serve the proposed developments without improvements. The City has asked CBBEL to analyze the existing sanitary sewer system, identify critical capacity locations, determine if improvements are required due to the proposed developments, and provide a recommendation to accommodate the additional sanitary flows generated by the proposed developments. The Sanitary Sewer Analysis scope has been organized into the following three tasks: Task 1 -- Data Collection: This task will include acquiring, if available, and reviewing the sewer as-builts, GIS data, sewer monitoring data, sewer CCTV, lift station pump run times, current water consumption data, and existing hydraulic model outputs to complete task 2. Task 2 — Existina and Proposed Condition Sewer Analysis: CBBEL will construct and calibrate an existing conditions sanitary sewer model based on the data obtained in task 1. The existing conditions model will provide the basis for the proposed conditions model and alternatives analysis. The additional flows from the three developments will be added to the existing model to determine if capacity issues exist in the sewer system. CBBEL has anticipated analyzing three (3) sewer system improvement alternatives in the proposed conditions model as part of this task. A meeting with the City is anticipated to review critical capacity locations and discuss preliminary proposed alternatives. Task 3 — Technical Memorandum with Cost Matrix: This task will include developing a technical memorandum summarizing the existing condition and capacity of the sanitary sewer system, the proposed conditions including the anticipated flows from the proposed developments, and recommended improvements to the sanitary sewer system to accommodate the proposed developments. The memorandum will also include an estimated cost for the recommended improvements. M3 City of South Bend Traffic Signal Improvements
