At the open house, staff heard concerns about the size of building. Staff has Phone: 952.227.1400 been working to try to reduce the building footprint and on ways to screen the Fax: 952.227.1404 building. Planning & Natural Resources The filtration plant is still being designed f ' p g g ed or the necessary capacity needed for the Phone: 952.227.1130 city. The iron and manganese filtration plant is planned for a total capacity of 6,000 Fax: 952.227.1110 gpm. The plant is proposed to have a process that is very similar to the gravity cast - in -place treatment process as the East Plant to provide consistency in the plant Public works operations and finished water quality. The plant will be designed for the ultimate 7901 Park Place treatment capacity needs of the city and will bring all the western wells and future Phone. 952.227.1300 952.227.1310 wells to the plant for iron and manganese filtration. The plant would be designed d soFax . treated water will be able to be pumped in the low and high zones. Senior Center Phone: 952.227.1125 Building Layout Changes Fax: 952.227.1110 The building layout has been changed since the May 9th work session as follows: Website www.ci.chanhassen.mn.us 1. The electrical room has been moved from the south side ofh ' ofthe building to the east side. 2. The generator room has been moved from the west side of the building to the east side. Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Todd Gerhardt West Water Filtration Plant: Plan Update July 27, 2016 Page 2 3. The non -water production area which includes the control room, chemical rooms, mechanical and electrical rooms have been lowered 6 feet in elevation to better screen this area of the plant and allow for a more gradual driveway grade. There are now stairs from the non -water production area to the process room. 4. The aeration process has been eliminated. The building for the aeration equipment has been eliminated to reduce the height and size of the building. 5. The size of the detention tank has been reduced by half. Eliminating the aeration process will require more chlorine to be used in the filtration process to oxidize the iron in the water supply although it will not affect the amount of chlorine that will be fed downstream into the water distribution system for disinfection purposes. WSB estimated that more chlorine will be consumed on a daily basis due to the elimination of the aeration process. Also, as the chemistry of the west well field potentially changes with the addition of new wells, the filtration process may become less efficient without the aeration process but the plant should continue to reduce the iron and manganese to acceptable concentrations in accordance with recommended Ten States Standards. The overall building length has been reduced from 178' 4" to 13 8' 4". The most the building is visible above ground is approximately 17' without a sloped roof. Building Exterior Design and Landscaping The goal of the site design is to have the building set into the hillside as much as possible to take advantage of the topography to decrease visual impacts. The building's exterior would be built with maintenance free materials and finishes such as stone, manufactured stone products or brick similar to the East Plant. Doors and windows, as well as, other fenestration could have more of a residential look than the East Plant and have a prairie -style architectural feel. Staff would like to use "earth tone" colors for exterior finishes. Below is an example of a prairie -style architectural structure. The use of evergreens and berms will likely be used at strategic locations to visually break up the building. The rest of the site and park will have additional landscaping with mainly deciduous trees. c:\users\jeans\desktop\wwtp plan review for parkandrec - 062216.doc Todd Gerhardt West Water Filtration Plant: Plan Update July 27, 2016 Page 3 Preliminary Cost Estimate The preliminary construction cost is approximately $19.5 Million which includes approximately $2 Million to construct the raw water lines from the west wells to the plant. More accurate cost estimates will be prepared at the completion of the 60, 90, and 100 percent complete phases of the design. The City has made application through the Minnesota Department of Health for grant and loan funds to assist in financing the plant. These funds come with specific requirements that would add cost to the plant construction but would lock in the interest rate at I% which is significantly below the rate the City could sell bonds. Site Acquisition The City purchased the site for the filtration plant in 2005 at the time the Lake Harrison development was approved. The City identified several sites for the future plant before the purchase was made. The parcel the City purchased was viewed as the best site for a future filtration plant. The site of the Children's Learning Center at the corner of W. 78th Street and Galpin Boulevard was one of the sites the City evaluated for the future filtration plant. The Children's Learning Center does have an outlot that is currently not being developed. This outlot is large enough for the filtration plant. It is estimated the outlot would be valued at about $1,000,000. The soils in the area are known to be poor and it is likely a building constructed on the outlot would need to be supported by piling or other structural techniques. The cost to extend raw water main from the current location to the plant and the necessary truck distribution water main is estimated to cost $1,500,000. If the plant were to be constructed farther south of W. 78th Street, the cost for constructing the trunk water main and the distribution main would be significantly higher. �CURDITT Y, City Park & Recreation Board Meeting Complete 90% Design and Cost Estimate City Council Meeting to Present 90% Design Neighborhood Meeting to Present 90% Design Complete 100% Design and Cost Estimate Planning Commission Meeting City Council Approves Bidding Documents Bid Opening City Council Considers Award of Construction Contract Construction Water Filtration Plant Start-up Attachments: Floor Plan Elevation Views Site layout Site Acquisition Memorandum c: Greg Johnson, WSB & Associates c:\users\jeans\desktop\wwtp plan review for parkandrec - 062216.doc June 28, 2016 August 2, 2016 August 8, 2016 August, 2016 August 31, 2016 September 6, 2016 September 12, 2016 October 11, 2016 October 24, 2016 November, 2016 — April, 2018 April, 2018 LLI LLJ Ix Z W -Z M W uj t Lb Ix 0. > U, -5 IX CL LL W CK w ul W Z UJ LL Z 4i 44 z C- z W w Z W CL T 1.9k K:\01694-720\Cad\Pmposed\Preliminary WSB\6-15-2016 MAIN LEVEL FLOOR PLAN.dwg, 6/21/2016 8:32:13 AM, Adobe PDF ii ii II ii ii 11 ii II 11 11 11 11 11 11 II It 11 11 11 ------------ 7771�\ II II II II II II 1 I I I a 1 II II 1 ©a II II II II II 11 II I II -------------- II I II 1 II .4 F03 _ _ _ _ ______ _ _________ _______I 0 -k > Z "n 0 0 0 0 0 01 01 0 0 0 I 0- Oro 01 0! 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 rao-of —04 0 0 0 0 0 0 0* 0 07 - 0 0 0 0 0 01 of 0 0 0 0 0 0 0 0 0i 0! 0 0 0 a O 0 0 0 0 01 01 0 0 0 moo 00 64 0 - su 0 0 0 O 0 0 0 0 0 0 a 0 d d 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 01 01 0 0 0 c3 q 0 0 0 0 4 la 0 0 0 0 0 - ------ 0 0 0 0 0 0 . ..... . 1 01 ......w ----4 w I 0..0-:0-'0 0 c/)N 0 0 0 0 0 0.: 01 0 0 0 0 0 0 0 0 0 0 0 O I O i O O O 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 -0 -0 '70 0 0 0 0 0 0 0 0: 01 0 0 0 0 0 0 0 0 0: 0: 0 0 0 c 0 0 0 Ct Ct 0 0 0 . 0 0 0 0 f o 01 0 0 a 1 1 : FTJ m 0 0 01 01 0 0 0 . .. ....... 0 0 0 4 0 4 . . . . . . . . . . . . . . . . . .

The sequestration process adds poly''ho-sphates to P the effluent Water and in, turn reduces the formation ofinsoluble iron fan mance nes o 'des which cause the water discoloration., prob] xi stainina, and taste and odoi. ems. Staff obtained costs for sequesterinathe west well water, Using averaslu. e: m.pnio Z� . , P rates from these wells,chcmical injection cost will average about $32,000.00/yr. Initial startup COStS will be approxim.ately $5,000.0 ,f r' tanks, pumps and injection Point installation. The effectiveness of sequestration can be limited by concentration. of constituents and w,1rJte.r temperature. In addition, polyphosphates can. begin to break down within. 24 h.ours, or less. reverting to an orthophosphate which has -no se q Lies terinor l el cpability4 Also, orthophosphates can serve as a nutric-nt to water system bacte na and other. microbes.

Topaz Drive. The site is approximately 5.4 acres. The majority of the site is on a steep hill with few mature trees. The site is centrally locatcd around the western wells and is close to the distribution network. The site is also central all located between the high zone and the low zone areas. The treatment plant would be desianed. to pump water to the hl. zone zone and the low zone without the Z:1 ko- 4i neat for an additional ex,ternal booster PLIMP station, The site Irl lows for the treatment t1lant to be built into the hillside and partially screened from the existing L -Ind future residential neighbo.t-lir oods (see -attached concept plans). Building the treatment plant. into the hillside will add rUpproximately $100,000 to the. construction of the plant. Properties on the e,---Ist side of Gal.pin BOUlevard would be screene d from the plant by a berm, In addition,these properties are sctback frot-n Gatpi_n Boulevard by it wetland Ulonr the east side of Galpin Boulevard. Additional raw water and distribution pipe network Would be required to brincy the. raw water from, Well Nos. 9 and 3 to the plant and distribute it outinto the network at an estimated. cost of $3 )90,000 (Section B). The purchase price for this s . ite is s estimated at $1,300,000. The Parks pe-C-irtment leas identified this site as a flood location for a srnall neichbot-hood park- and steddino hill. Funds for purchasin, ti e p-operty .1 would come frorn. the water utility fund and park dedication fund. The ')003 Master W11ter Plan considered: this site desirable for a watcr treatment plant.

The property is currently not for sale, Ifthe City would coni theproperty, costs for land are anticipated to be higher. The '2003 Master & Vf Z::� Water Plan rated this site to and did not considerit a desirable site because the shape of the parcel would ma'ke it difficult to provIde adequate buffer betNveen the Water treatment plant and the adjacentresidential parcels.
