COMPREHENSIVE WATER PLAN UPDATE IN COORDINATION WITH 2040 COMPREHENSIVE PLAN UPDATE CITY OF RAMSEY, MINNESOTA A.P URPOSE The purpose for this report is to update the Citys 2012 Comprehensive Water Plan based on current (2017) population and land use projections. The 2012 Comprehensive Water Plan included a plan for meeting the Citys needs based on development projected within the Citys 2030 Comprehensive Plan. The 2012 Comprehensive Water Plan outlined infrastructure needs and included an implementation schedule based on the anticipated development. City staff has identified development which has occurred since the 2012 study was completed and has provided projections for development which is likely to occur in the next 23 years (Year 2040). This report evaluates the impact of the recent and projected development on the proposed schedule for water infrastructure implementation. Typically water system improvements are funded through a combination of Water Availability Charges, trunk charges, and water usage fees. We have prepared one option for funding the water system which should be reviewed and discussed with the Citys financial advisor prior to setting or adjusting any charges or fees. B.S2012CP UMMARY OF INFRASTRUCTURE REVISIONS TO OMPREHENSIVE LAN Infrastructure expenditures were based on the Citys Capital Improvement Plan for the years 2017 to 2020. We also identified several capital improvement projects which will need to be implemented between 2021 and 2040. 1.Water Distribution System The water distribution system is depicted on Figure 1. Water wells, towers and existing and proposed water mains are shown on the graphic. A summary of revisions (when compared to the 2012 map) is as follows: 1.Removed both alternative Water Treatment Facility locations and related surface water pipes. 2.Updated the existing water main locations to match the current City water map. 3.Loop #1 a.Revised to reflect the Bowers Drive water main as a lateral main rather than a trunk facility. b.Added a loop along Puma Street and Alpine Drive. c.Added a water main on Riverdale Drive, west of Armstrong Boulevard to complete the loop in that area. nd d.Removed the small loop east of Armstrong Boulevard on 142 Avenue. e.Revised the segment east of Armstrong Boulevard, on Riverdale Drive, from proposed to existing. 4.Loop #4 was revised to connect from one existing 12 main to another. The southern existing 12 pipe appears to have been installed since the 2012 report. City of Ramsey, Minnesota R16.110056 Page 1 Comprehensive Water Plan Update Prepared by Bolton & Menk, Inc.
