Fellows Street Drainage Design ( CArcina December 10,2012 V JFNew WORK SCOPE We have divided our proposed scope into two parts — Part 1: assisting Christopher Burke Engineering (CBE)with drainage design for the Fellows Street—Ireland Road intersection and Part 2: drainage design in areas outside of the Fellows-Ireland intersection that contribute to drainage problems on Fellows Street.The drainage problem areas as we understand them include 1)the intersection of Fellows Street and Walter Street, 2)on Fellows Street just south of the intersection of its intersection with Barbie Street and 3)at the intersection of Fellows and Chippewa Avenue. For Part 1, we have assumed that we will work like a sub-consultant to CBE (though contracted through the City of South Bend), helping them develop a drainage solution for the Fellows-Ireland intersection design that is acceptable both to the City of South Bend (the City)and neighborhood residents. We will provide assistance with conceptual drainage design and details and specifications as needed, but the final construction documents remain CBE's responsibility. For Part 2 we have assumed that we will work as the primary design engineer;that is, the design will be prepared and stamped by Cardno JFNew. But we will prepare our drawings and specifications so they can be efficiently incorporated into the overall CBE bid package for the larger project. TASK 1: PROJECT COORDINATION This task covers our effort to coordinate with the City and with CBE.This includes correspondence on an on-going basis and face to face meetings.We have assumed at least one more meeting with the City and CBE and at least one meeting with stakeholders in the Fellows Street neighborhood. Subtasks include: a. Coordination with CBE and City of South Bend b. Stakeholder Meeting(s) Deliverables: 1. Project slides for stakeholder meeting(s) TASK 2: HYDROLOGIC/HYDRAULIC MODELING We will develop an explicit model of runoff and conveyance existing conditions for the entire drainage area that contributes runoff to the Fellows Street problem areas.The model will include runoff from the Fellows-Ireland intersection, the runoff contributions from Walters, Barbie and Chippewa Streets as well as all the runoff generated in and along Fellows Street. Model results will feed into the design process(TASK 3 below). We will also develop a proposed conditions model that incorporates the various design elements, so that the runoff control provided by each design element is accounted for in the design of"downstream" runoff controls. Subtasks include: a. Compile GIS/CAD coverages b. Delineate drainage areas c. Prepare existing conditions model d. Prepare proposed conditions model(following Task 3.d. below) Deliverables: 1. Existing and proposed conditions model input and output files 2. Brief technical memorandum on model results File#0811208.00 www.cardnojfnew.com
