May 13, 2024 RE: Proposal for Professional Engineering Services Water Meter Vault City of Roseville Roseville, MN SEH Project No. ROSEV P-178749 Jesse Freihammer, P.E. Public Works Director City of Roseville 2660 Civic Center Drive Roseville, MN 55113 Dear Jesse: The City of Roseville is proposing to replace the three (3) below-grade water meter vaults that that serve the connections with the City of Arden Hills. Our staff has a good deal of experience with such structures from past projects. It also so happens that we are currently working on three (3) meter vaults for the Randall Community (Rural) Water District in South Dakota, so the timing of this project is perfect! Acting on your invitation, SEH is pleased to submit this proposal for professional engineering services to prepare construction phase plans and specifications to support the City’s endeavor. The following outlines our understanding of the project and our proposed scope of services for assisting the City of Roseville (Roseville) with this meter vault replacement project. PROJECT BACKGROUND The City of Roseville provides water service to the City of Arden Hills at three (3) separate locations. These water system connections have been in place for many years and the overall useful life of the meter vaults is considered to be diminished to the point where replacement is desired. Roseville’s proposed schedule is to replace one (1) meter vault in late summer or fall of this year. Replacement of the other two (2)meter vaults will occur at a later date. In general, the existing meter vaults are located at: 1.) County Road D and Cleveland Avenue; County Road D and Fairview Avenue; and 3.) Hamline Avenue, east of Snelling Avenue. The Hamline Avenue location utilizes a 16” water service connection between Roseville and the City of Arden Hills, while the other two (2) locations offer 12” connections. Meter readings and upkeep of the vaults is Roseville’s responsibility. Under normal circumstances, water flows from the Roseville system into the Arden Hills system. However, the hydraulic gradelines (HGLs) that the Roseville and Arden Hills water systems operate at are close enough in elevation that water can actually flow back from the Arden Hills system into the Roseville system should the Roseville system experience an unexpected drop in their HGL. PROJECT SCOPE From our Monday, April 22 Team meeting we understand that the City of Roseville is interested in developing a set of construction documents for the initial meter vault replacement project that can be used for the future replacement of the other two (2) meter vaults. Other parameters that Roseville has interest in for this meter vault replacement project include: 1.New electromagnetic (mag) meters with AMI/AMR end points that are compatible with the existing Qbhf!217!pg!257
