INTRODUCTION AND INITIATION OF REPORT IThe City of Lake Elmo has three distinct water systems. The purpose of this Report is to look at the feasibility of interconnecting the Old Village water system to the Lake Jane Iwater system. The reasons the City would like to interconnect these two systems include: A. Financing of a new elevated tank. As outlined in previous reports, the current elevated tank is far too small to serve the Old Village area. With additional users on Ithe systems, the cost of a new tank can be paid off sooner. B. Provide water service for residents of new developments. The routes for the Iwatermains to interconnect the water systems will pass through two planned developments. The City will be able to capture connection fees, while at the same Itime eliminating the need for a large number of new residential wells. C. Remove the Lake Jane water system from the City of Oakdale water supply. The ILake Jane water system was constructed to provide drinking water to homes within the well advisory area around the former Lake Jane Landfill. The Cities of Oakdale Iand Lake Elmo have a joint powers agreement for water service to these residents. This agreement expires in 2020. This agreement limits the area which can be Iserved, and sets the rates our City must pay. These two items have been an impediment to our City making this water system break even financially. ID. Provide public water to property owners along 31st Street. These properties are I currently outside of the SW-1 Well Advisory Area. However, traces of some chemicals have been found in their wells. This project would allow residents to connect to a public water supply. I E. Provide a third source of water to the Old Village water system. Routine Imaintenance requires that a well be shut down for a period of time every few years. By having a connection to Oakdale's water system, we have a back-up source of Iwater should we have an emergency while one well is shut down. This Report was initiated by the City Council. 1 13186.001 I 1 tII. EXISTING CONDITIONS ' The Old Village water system is currently served by City Well Nos. 1 and 2. They pump at 500 and 1,000 gallons per minute, respectively. There is a 75,000 gallon elevated tank. tThe Old Village system is split into a high pressure system which serves the Carriage Station area, and a lower pressure system that serves the remainder of the Old Village. ' There is a valve that allows water flow between the two pressure zones in the event of an emergency. The Lake Jane system is supplied with water from the City of Oakdale. The watermains there are sized to only provide drinking water, not fire protection. A new well would not change the ability of the system to supply water for fire protection. ' III. PROPOSED IMPROVEMENTS ' As shown in Figure 1, two watermains are needed to tie the two systems together. A new 500,000 gallon elevated tank is proposed at the Public Works site. For the northern loop, a 16-inch watermain would be extended from the intersection of 39th Street and Lake Elmo Avenue northward to 43rd Street. At 43rd Street, the watermain twould continue westerly, through a proposed easement, to the Tapestry subdivision. A 16-inch watermain would continue through the subdivision, to 45th Street. The watermain would follow 45th Street/Jane Road to Jamaca Avenue. At Jamaca Avenue the watermain would extend south to the Public Works site, where the new elevated tank is proposed. The southern loop would extend 12-inch watermain from the intersection of 39th Street and Lake Elmo Avenue, south to TH 5, westerly along TH 5 and Stillwater Boulevard to 31st ' Street. A crossing of the highway and the railroad would be made at that point. The 12-inch main would be extended to a proposed subdivision along 31st Street. A 500 000 allon elevated storage tank is needed to address current and future needs of 9 9 this water system. The tank is being sized using the Ten States Standards for Water System design. ' Use of the Public Works site will result in a tank that is 145 feet high. For comparison, the existing Old Village elevated tank is 125 feet high. This tank will result in a normal ' 2 1 3186.001 1 operating pressure of 50-80 psi throughout the system. The area of the Old Village water system south of the railroad tracks will need to have the pressure lowered in order to avoid ' excessive static pressure in that portion of the system. Two pressure reducing valves will be needed at the crossings near the railroad tracks. 1 IV. RIGHTS-OF-WAY AND EASEMENTS A utility easement will be needed at the western end of 43rd Street so watermain may be extended to the Tapestry subdivision. All other work should be done in existing City of Lake Elmo rights-of-way, or by permit in County and State rights-of-ways. ' V. PERMITS A Utility Permit from the Minnesota Department of Transportation (Mn/DOT) for work in the rTH 5 right-of way. A Utility Permit from Washington County for work in the CSAH 17 right-of-way. A Utility Permit from The Burlington Northern Santa Fe Railway Company for crossing of the railroad tracks. Minnesota Department of Health for a watermain extension and elevated tank construction. Valley Branch Watershed District for erosion control. VI. ESTIMATED PROJECT COSTS We have broken the project down into phases, according to the order the jroects will be P completed. Phase I 1. Watermain Extension To Tapestry)( p ry) $ 458,600.00 2. Watermain Oversizing at Tapestry $ 66,500.00 Phase I Total $ 525,100.00 3 13186.001 1 Phase II 3.

Remove Existing Elevated Storage Tank $ 41,000.00 11. Pumphouse No. 1 Replacement $ 390,000.00 ' Phase IV Total $ 431,000.00 TOTAL IMPROVEMENT COSTS: $3,849,300.00 VII. FINANCING OF IMPROVEMENTS The improvements are planned to be financed entirely by a Water Availability Charge 1 (WAC), water sales, and tower rental fees. No assessments are planned. It is recommended that the WAC be increased to $3000.00 per unit to cover the estimated project costs. Project cost estimates were prepared using this WAC amount for new users. A detailed breakdown of projected costs and revenues has been prepared and the figures will be reviewed by our Auditor prior to the selling of any bonds. Projected income and ' 4 13186.001 1 bond repayment will be influenced by the rate of development in the service area, timing of the projects, and actual project costs. 1 VIII. PROJECT ASSESSMENTS No assessments are anticipated. 1 IX.
