City Council approval requires a simple majority vote of the City Council present. BACKGROUND The Minnesota Department of Natural Resources requires each community to apply for water appropriation which is covered under Minnesota State Statues, Section 103G.291. These permits are typically given for a 10 -year period. Staff has been working with the DNR on this appropriation permit for over two years. DISCUSSION The new permit is anticipated to cover the City for the next 10 years. The new appropriation allows for 1.586 billion gallons of water to be pumped annually with a peak pump rate of no more than 9,850 gallons per minute. The DNR is requiring the City install a monitoring well in Bandimere Park in conjunction with the new Well # 14 permit. This work is nearly completed and should be operational before Well #14 comes on line. Two additional wells are planned to be constructed in the next 10 years. These wells will be permitted separately and the DNR may require the City to install additional monitoring wells. The DNR continues to strongly encourage the City to adopt a time -of -day watering constraint ordinance to reduce peak demand.

This approval is effective upon the Department's receipt of a completed copy of the attached "Certification of Adoption" form. Please return the form to my office as soon as the City officially adopts the Plan. In conjunction with Water Supply Plan approval, Water Appropriation Permit 1981-6089 is amended authorizing an increase in volume from 1200 to 1586 million gallons per year. Previously authorized wells #10, #11, # 12, and #13 have been added to the permit. Wells # 14, #15, #16 are preapproved. These wells arc expected to be Prairie du Chien wells and located at the sites referenced as 14, 10, and 2 (see attached memo dated January 8, 2009 from Paul Oehme to John Gleason). This Amendment should cover the City's water needs for the next 10 years, per your Water Supply Plan. The City must notify the DNR at the time the new wells are activated and provide the well record, pumping test results, and the completed well notification form (copy attached). Please carefully review Condition #13, #14 and #15 of the permit. The City is already working to meet Condition 13 as we understand that you have recently constructed, at our request, two observation wells in the city park west of Lake Riley - one screened in the Prairie du Chien and one in the buried artesian aquifer. We appreciate the City's cooperation and interest in collecting water level data. Condition 14 states that the City is not authorized to appropriate water from well #14 until collection of monitoring data from the new observation wells is initiated. Condition #14 also requires that the City consult with the DNR prior to constructing wells #15 and #16 in order to review monitoring data and finalize the location, source aquifer, depth, and pumping rate. Condition 915 requires submission of the daily record of the static water levels recorded by the SCADA system for ail production wells The City calculated in 2008 ifs average residential per capita demand over the past five years to be 93 gallons/day, and it's average maximum day to average day demand at 2.7. This demand is higher than the 2002 metropolitan average of 75 gallons/day and 2.6, respectively. The Plan describes several programs the City is considering to implement to lower demand. The DNR and Metropolitan Council encourage the City to continue implementing programs to reduce demand. We strongly recommend that the City adopt a time-of-day watering restriction. Lawn watering before 10:00 a.m, and after 6:00 p.m, can improve lawn www.dorsta►e.w.us 0*1 AN EQUAL OPPORTUNITY EMPLOYER %J� PRINTED ON RECYCLED PAPER CONTAINING A MINIMUM OF Iffc POST•CONSUMER WASTE Mr. PaulOehme City of Chanhassen March 29, 2010 Page 2 watering efficiencies by reducing water lost to evaporation and wind drift. If Chanhassen's water demand is decreased the need for new wells and associated infrastructure may be delayed or eliminated. We also encourage the City to continue to educate its customers on how they can reduce household water use.

The measurements will be sent to the DNR electronically. The Division of Waters will provide an Excel spreadsheet template upon request. The information provided on the reporting spreadsheet includes: • Permit Number • Permitee Name • Well Address or location of the monitoring well • Permitee Well Number (or well name) • Minnesota Department of Health Well Number — MDH Unique well number • Measuring point distance above ground surface — in feet • Date of Measurement Time of Measurement — in 24 hour time • Depth to Water below ground surface — in feet If the information is collected from a data logger, the data from the logger should be assembled to fit this spreadsheet and submitted to the DNR. Hand measurements will also be reported on the spreadsheet. Unless stated otherwise in your permit, measurements from the permit monitoring well will be collected monthly and submitted your DNR area hydrologist on a quarterly basis.

LeMon; Kevin Crooks Subject: RE: Water Supply Plan Information Attachments: Figure Jack, Thanks for the update on our supply plan approval. I have attached a drawing showing potential well sites we recently evaluated. eased on our water modeling analysis, land availability, construction costs and were we will need the water in the future the sites we have selected for future wells in the next 10 years are site 14,10 and 2. All three wells would be Prairie du Chien/Jordan. The next well we are proposing to drill would be in 2010 at site 14. The timing of the next two wells, at sites 10 and 2, would be development demand dependent. The City is somewhat flexible on these two future sites if the DNR has objections. The City would like to obtain a 10 year permit instead of a 5 year. Let me know if you have any questions or need additional information. Thank you, Paul Oehme, P.E.

Thanks for taking the time to talk. We are still in the process of determining if a rate structure like Chanhassen's that includes a small volume of water with the base fee - can be considered a conservation rate. I will notify you when we decide, hopefully in the next 2-3 few weeks. Also, you mentioned that since Chanhassen submitted the revised Water Supply Plan last May that you had additional information on the location of the future wells. Could you please forward this information to me? We can use this new information to re-evaluate the appropriateness of a 10-yr permit.
