L Mr. Michael Grochala City of Lino Lakes, MN October 27, 2014 Page 2 WSB's project scope and proposed work plan as presented is based on our understanding of the project, discussions with City Staff, and experience on similar projects. The following are the major tasks that will be performed in preparing the City's water distribution system model. Task 1: Project Management and Coordination Project management is a key task included in each project undertaken by WSB. This task consists of management and administration, project coordination, and overall communication with the City. Proper completion of this task will help keep all affected parties routinely updated and informed regarding project issues, as well as keep the project on schedule and within budget. The proposed work plan will include up to three meetings with the City as deemed necessary. Project milestone meetings may include: • Project kickoff/scoping meeting; • Existing and future water demand discussion meeting; and • Existing water system evaluation and future improvements review meeting. Task 2: Existing Water System Data Collection WSB will utilize as much as possible the data that is currently in-house; however, there may be some amount of data necessary to complete the model will be collected from the City. The GIS water system information and existing ground contours in GIS format will be used and it is assumed that the pipe sizes are accurate or will be updated prior to the WaterCAD model is initiated. Information that is assumed to be provided by the City includes: • Existing and future land use map in GIS format; • Record drawings for storage, supply, and treatment, including pump curves; • Annual DNR Public Water Supply Inventories; • Water pumping data; • Water use records summarized by customer category; • Water use records for the top ten water users for the past two years; • Guidance on relationship between customer billing category and existing land use; • Hydrant flow testing data for some locations; • Information regarding currently proposed water system improvements; • Information related to the existing distribution system that include low/high pressure areas, tower cycling and backflow conditions, and main break history; and • Necessary fire flows for specific properties within the City upon which the ISO Classification was based. No hydrant flow tests are included in the scope of work. It is assumed that the City has recent and accurate hydrant flow testing that can be used to calibrate the water system model. See Task 7 for information regarding hydrant flow testing as additional services. Task 3: Existing Water System Model Development and Evaluation An existing distribution system WaterCAD model will be developed based on the existing water system map. The GIS shape files and a map of the existing water system developed will be
