Background Money has been budgeted to replace existing water and sewer infrastructure that is old and/or undersized. The downtown water infrastructure has been identified as the highest priority. Criticality ratings have been assigned to priority pipes based on pipe size, material, and fire flow. B. Proposed ProIect This project is for design of water line replacement in NW 4~' St. which has been identified as one of the most critical water lines within the downtown azea. This water line consists of dated and undersized cast iron. IV. IMPACT A. Strateig c Im acct: This project meets our mission requirements to indentify and prioritize work to anticipate, plan and provide public services and facilities that support the needs of our growing community and ensure modern reliable facilities while maintaining financial stewardship. Infrastructure replacement is an important part of a Capital Improvement Program. Investing yearly in the replacement of infrastructure nearing the end of its life cycle, greatly reduces the risk of costly failures, decreased fire protection and increases the reliability of the water distribution system to efficiently provide service to our customers. B. Service/Deliver,~pact: Replacement of this water line increases fire flow capabilities and limits the possibility of costly water line breaks. C. Fiscal Impact: Project Costs Consultant Agreement $25,000 Project Funding Enterprise Fund for Water/Sewer Main Replacement $300,000 V. ALTERNATIVES A. The City could defer the replacement of this water line and risk breakages that are costly and cause the loss of service to customers. Fire protection capabilities aze also limited due to reduced fire flow. Page 2 of 3 B. The City could choose not to replace this water line which would result in the same risk of costly breakages, service interruptions and reduced fire flow. VI. TIME CONSTRAINTS Council's approval will allow completion of the design of the project by December of 2009. Once the design is complete, construction of the project could be approved, go out to bid and started by the Spring of 2010. VII. LIST OF ATTACHMENTS A.

Pine Ave. TASK 10094.1 Coordination and Review/Approval Meetin4s with the City of Meridian A. Attend initial project start-up meeting. Clarify work activities/responsibilities, obtain materials and "as constructed drawings" from the City. B. Provide preliminary drawings showing utility existing utility locations from survey data, including the existing water line locations and other topographic information for the utility companies. Attend meeting with utility companies to discuss project impacts to utility facilities and the scope and schedule for the project. C. Monthly administration, project budgeting, and invoicing. D. Internal project coordination and coordination with the City throughout the project. Anticipate one 3-hour meeting once a month for two months to coordinate with the City of Meridian.

Assumptions: TransCivil assumes the City of Meridian will provide "as constructed" drawings for both the sanitary sewer and potable water systems, other known information such as street sections, other utility systems and surface drainage facilities are also assumed to be provided. TASK 10094.2 Alternative Solutions A. TransCivil personnel will develop two alternatives to maintain water service to the adjacent property owners during construction of the new water line. The two alternatives will include: ^ Furnishing and constructing a temporary line capable of providing potable water. ^ Constructing new waterline adjacent to existing and switching existing services to the new line. Old line to be capped and abandoned in place. B. TransCivil personnel will develop a preliminary construction cost estimate for the City of Meridian's review. TASK 10094.3 Topographic Surveys A. TransCivil will contact all adjacent property owners by letter explaining the project. Conduct control surveying in order to establish and verify the property lines and right-of--way of the parcels within the project limits. B. Research Record of Survey drawings and Subdivision Plats along the corridors to delineate the right-of--way. C. Conduct control surveying to establish project control datum. D. Draft right-of-way and property lines in AutoCAD format and show on the topographical base maps. E. Perform topographic mapping of the project site, approximately 3100 lineal feet. Mapping shall include the locations of surface features on the site to include edge of pavement, roadway striping, pipe crossings and inverts, ditches, fences, adjacent roads, driveways, monitor wells, visible utilities, utility information as marked in the field by locating companies, pothole locations and depth to lines, etc. F. Prepare a base map from field data in AutoCAD format. Provide electronic file of final topographic base map and right- of-way delineation in AutoCAD format. Provide ASCII file of survey data containing point; northing, Basting, elevation and code information.
