Legal counsel has previously reviewed the agreement. The City uses consultant services to augment the City's Engineering Department. These services are selected based on proposals received in response to a project work scope prepared by the City. Normal practice is to have a general agreement with the consultant firm. A supplemental contract is then written off of this general agreement for each project. This allows the individual project contracts to be much shorter and eliminates the duplication ITOm contract to contract. Currently, the City has no general agreement with SEH. Additionally, staff is recommending that the City Council approve a contract for engineering services with SEH in the amount of $30,800 for the preparation of a Wellhead Protection Plan. On July 10, 2000, the City Council authorized staff to obtain proposals for engineering services on the preparation of a Wellhead Protection Plan. It was further authorized that the consultant would be selected based on the qualifications of the firm and not simply the cost of the proposal. The City received seven submittals in response to the request for proposal. After reviewing the proposals, two firms (SEH and Barr) were called back for interviews. Upon completion of the interviews, the unanimous choice among staff was SEH. Staff believes that the firm's experience (recently completed a similar wellhead plan for Minnetonka) and approach to the project (SEH plans on fully staffing the required well pump test) sets them apart from their competitor. Failure to approve these agreements will delay the plan's completion .

Understanding of Scope and Deliverables SEH understands that the City of Chanhassen intends to fulfill the wellhead protection requirements as put forth in Minnesota Rules Chapter 4720. This proposal is in response to the City of Chanhassen Request for Proposal- Wellhead Protection Plan PW 379 dated August 22, 2000. Our understanding of the scope is summarized below. Scope - Part I I. Delineate the Wellhead Protection Areas (WHPAs) As discussed in the December 3, 2000 MDH scoping letter to the City of Chanhassen, SEH proposes to utilize the Hennepin Conservation District's MLAEM model of the Prairie du Chien/Jordan aquifer to delineate the WHPAs. SEH has utilized this model in the delineation of Edina's municipal wellhead protection areas. We are currently completing an assessment of this model for the Minnetonka wellhead protection delineations. We are familiar with the model and experienced with modifying it to meet the criteria requirements. Prior to utilizing this method, SEH will meet with City staff and the MDH to ensure that it is the most effective and efficient method available and that it is accessible through the more recent versions of the MLAEM software. We understand that the delineation method must incorporate the five criteria listed in Section 5520 of the Rule; Time of Travel, Flow Boundaries, Daily Volume, Groundwater Flow Field, and Aquifer Transmissivity. II. Pumping Test SEH has conducted several pumping tests in accordance with the wellhead protection rules. We understand that a pumping test will be required for the City of Chanhassen's wellhead protection plan. The pumping test will be utilized to determine aquifer transmissivities surrounding the seven city wells. It is assumed that the MDH will supply the equipment for the test including the pressure transducers and data logger(s). SEH will prepare and submit to the MDH an aquifer test plan, conduct the test, provide staff to install, download and remove the necessary equipment, evaluate the results, and calculate the aquifer transmissivity as part of this project. III. Drinking Water Supply Management Areas (DWSMAs) SEH will develop the DWSMAs utilizing existing electronic data of the city parcel, street, and zoning maps. The DWSMAs will be prepared in accordance with the wellhead rules and will be developed to most closely reflect the WHPA delineations. SEH will work with City staff in ensuring the DWSMAs mesh with the needs of the City and where possible existing zoning maps. IV. Vulnerability Assessments SEH understands that vulnerability assessments are required for each well and DWSMA. SEH will review and update the well vulnerabilities assessments previously conducted by the MDH. SEH will evaluate the geologic data collected during the delineation of the WHP As to assess the vulnerabilities of the DWSMAs. The vulnerability assessments will be conducted in accordance with the wellhead protection rules. V. Meetings Effective communication is essential to the success of the project. We intend to work closely with the City staff throughout the project. Based on the RFP it is our understanding that several formal and informal meetings will occur throughout the project. For estimating purposes, we are assuming five meetings at two hours each. SEH has several tools available to ensure effective communication. Every SEH staff member has voice mail and an e-mail address. The SEH project manager can also be reached via cell phone. Short Elliott Hendrickson Inc. Page 1 Understanding of Scope and Deliverables, cont. Deliverables - Part I Following is our understanding of the project deliverables. I. Draft Report Four copies of a draft report will be prepared which presents the delineated Wellhead Protection Areas (WHPAs), the Drinking Water Supply Management Areas (DWSMAs), and the Vulnerability Assessments. The draft report will include all supporting documentation, and electronic data files to meet the wellhead protection rule requirements. The geographic data will be presented in ArcViewœ format using UTM-meters (NAD 83 Datum). II. Final Report The final report will be updated to respond to comments from City and MDH staff. Four copies will be provided. III. Project Work Products Model input sets, data files, metadata annotation and the WHP A delineations will be provided as requested in the RFP section 3.0. SEH is familiar with these formats and requirements and has provided this data in an acceptable format to the MDH on numerous similar projects. Scope - Part II I. Scoping Meeting The second scoping meeting will define the level of effort required for the second phase of the wellhead protection planning. SEH wiJI prepare for and facilitate that meeting as required. II Contaminant Source Inventory A this time it is assumed that the contaminant source inventory will only require an inventory on existing wells and improperly abandoned wells within the DWSMAs defined in the first phase of this project. The locations of these wells wiJI be presented in the Arc Viewœ format as discussed above. This method is cost effective and is preferred by the MDH. III. Wellhead Protection Plan (WHP) SEH will prepare a WHP plan in accordance with the wellhead protection rules. SEH wiJI revise the WHP to address comments received from local LGU's and the general public. The WHP plan will be presented at the required public hearing. SEH has presented wellhead protection issues and plans at several City Council, Planning Commission and Utility Commission meetings. It is assumed that the City will be responsible for scheduling, preparing, and publishing announcements for the required public meetings and hearings. IV. Meetings Communication wlm City staff will be very important for the second phase of the wellhead protection plan. The second phase is a planning document and input from the City is critical for a successful plan that can be implemented. This proposal assumes five meetings at 2 hours each. Deliverables - Part II A final wellhead protection plan will be submitted for the Minnesota Department of Health's approval. Short Elliott Hendrickson Inc.

Page 4 : ! fi t! ¿t Project Experience and References Related Groundwater Experience The following is a list of recent SEH wellhead protection and groundwater modeling projects. City of Edina, Minnesota SEH was retained by the City of Edina to delineate wellhead protection areas. SEH modified and refined the Hennepin County groundwater computer model. MLAEM (Multi-Layer Analytic Element Method) and CZAEM (Capture Zone Analytic Element Method) software was utilized to delineate wellhead protection areas (WHPAs) and drinking water supply management areas (DWSMAs) for the 18 municipal, multi-aquifer wells in the City. SEH worked in conjunction with Hennepin County and the MDH to complete the project in a cost-efficient and effective manner. In addition to the WHPAs, DWSMAs, and pumping test, vulnerability assessments of the aquifer and wells were completed, and approved by the Minnesota Department of Health. Minnesota Department of Health SEH completed wellhead protection area delineations for Anoka County Community Public Water Supplies in the deep Quatemary Aquifer. The project included creation of a hydrogeologic conceptual model, regional groundwater flow model, refinement at wellhead areas, and wellhead protection area delineations. The model was used to delineate 10-year time-of-travel capture zones. City of Paynesville, Minnesota SEH, working with the City of Paynesville and the Minnesota Pollution Control Agency (MPCA), has completed wellhead protection delineations and vulnerability assessments for four municipal wells in Paynesville, Minnesota. SEH utilized the MLAEM/2 groundwater modeling software to delineate the wellhead protection areas and drinking water supply management areas. SEH is coordinating efforts between the MDH, MPCA, Rural Water Association, and City staff. City of Hudson and North Hudson, Wisconsin SEH delineated wellhead protection areas for five existing and two proposed municipal wells in the City of Hudson and the Village of North Hudson, Wisconsin. The project involved an extensive hydrogeologic and geologic investigation of the region. The wellhead protection areas were defined using well pumping rates, time of travel, transmissivity, porosity, aquifer gradient, flow direction and vulnerability. The U.S. Environmental Protection Agency (EP A) WHP A software program was utilized for this study. The EP A WHPA program is a modular, semi-analytical groundwater flow model. The module utilized for this project was the RESSQC. RESSQC delineates time-related capture zones around multiple pumping wells. This project also involved contaminant source inventory, wellhead planning and management, ordinance . formulation, public involvement/education, and zoning. City of Burnsville, Minnesota SEH has developed a 3-dimensional MLAEM groundwater model for the City of Burnsville. SEH utilized the MPCA Metro Model as a base model. The project refined and calibrated the model near the wellheads and a large limestone quarry. The purpose of the model is to develop wellhead protection areas, DWSMAs, site several new wells, and look at impacts to surrounding features such as landfills, quarries and wetlands.
