Exhibit A- Engineer’s Services <br /> <br />DTSB Stormwater Plan - Scope of Services <br /> <br />Page 13 of 17 <br /> (Exhibit A- Engineer’s Services) <br />Understanding of the Assignment <br /> <br />It is the understanding of McCormick Engineering, LLC (MCCORMICK) that the City desires to provide a <br />separate stormwater system to convey discharges from City Right-of-Way and potentially from <br />development and redevelopment areas in the Downtown South Bend (DTSB) service area through a <br />variety of existing or new stormwater outlets to the St. Joseph River. The project will seek to provide the <br />necessary separate stormwater sewer sizing to accommodate levels of development desired by the City <br />based on the appropriate levels of development agreed to by the City during the course of the analysis. <br />The general locations of the DTSB services area is shown in Figure 1. <br />Scope of Services <br />Study and Report Phase <br /> <br />MCCORMICK will perform the following tasks to complete the noted work: <br /> Perform the calculations needed to meet the requirements of Scope Item 1 in the attached <br />Project Charter. <br /> Perform the calculations needed to meet the requirements of Scope Item 2 in the attached <br />Project Charter. <br /> Assist the City in the Proposed Stormwater allocations for new developments and redevelopment <br />outlined in Scope Item 3 in the attached Project Charter. <br /> <br />Preliminary Design Phase <br />MCCORMICK will perform the following tasks in order to complete the noted work: Prepare outline <br />specifications, opinion of probable Construction Cost and other documents outlined in Section A1.02 of <br />the Contract. <br /> <br />As part of the Preliminary Design Phase, McCormick Engineering anticipates the following Tasks: <br /> <br />1. Updated Stormwater System Study <br />- Prepare a hydrologic and hydraulic analysis of conceptual proposed storm sewer networks <br />to serve the DTSB service area, utilizing the capacity in known storm sewer outfalls to the St. <br />Joseph River, when possible. <br />- Update the 2015 PER data to include the latest available LiDAR topography and soils data <br />- Update the subareas of interest to reflect the DTSB service area maps <br />- Size appropriate separated storm sewers to reflect four scenarios of development <br />contributing to the storm network:
