The City Attorney shall draft and the developer shall execute a "Grant of Permanent Easement for Public Drainage and Utility Puiposes" document. This document shall be recorded with the metes and bounds subdivision. Todd Gerhardt 2061 West 65t�' Street Metes & Bounds Subdivision ��;�''n-o-��June 8, 2015 Page4of12 A i•oadway, drainage and utility easement must be dedicated over the portion of the existing cul- de-sac within the property and 15 feet beyond the edge of the road. Pi-ior to recording the subdivision the developer shall pay the $45 GIS fee: $25 (subdivision)plus $10/parcel. STREETS I The proposed subdivision is adjacent to West 65�' Street, a 25-foot wide public street within a 60-foot wide right of way without curb and gutter. Tlus st1•eet was constructed in 1979 and was overlaid in 2013. The cui��ent standard foi-new streets within Chanhassen is 31 feet wide with curb and gutter. Staff does not recommend that the developer install curb and gutter along the property frontage since the remainder of the roadway would remain a rural section. UTILITIES There is one sewer and one water service within West 65�' Street that provides service to the existing hoine. T�, a_._'.,N_�N..,r.,.,_., *., ..�„+w" �.._.. .,_.._. ..�. .._o*� *�,o _.__�*;�n',^,ro. .. . , . .. . .__ ____a� > > ,,.�;�;�,,, �4'+or ., a f�oo�o �1,.,.,, .. ,..lo > > ' �� Currently there is no water sel•vice or sanitary sewer service to Parcel 1. The proposed locations of the services are shown on the utility plan as a reference; the developer will not be installing the water service or the sanitary sewer service. Before a building permit is issued for Parcel 1, the water service and sanitaiy sewer service must be installed. The sanitary sewer is within West 65t�' Street, therefore, installation of a sanitary sewer service will require cutting into and patching the city street. A Work in Right of Way permit must be obtained before installing the water and sanitary sewer service; an escrow for street repair to ensure that the street is restored shall be part of the permit requii•ements. The estimated cost of the street repair was $10,000 in 2014. The escrow amount shall be adjusted according to the construction costs at the time the Work in Right of Way permit is issued. Sewer and water hookup charges are due for the new lot, a portion of which shall be collected befoi-e the metes and bounds subdivision is recorded: Water: 1 unit x $-l�� $1,957/uiut=�C $1,957 Sewer: 1 unit x �4 $677/unit =�-FC4-$677 Todd Gerhardt 2061 West 65r�' Street Metes & Bounds Subdivision "�r�� ni SJune 8,2015 Page5of12 If the metes and bound subdivision is recorded after December 31, 2015, the partial sewer and water hook-up rates in effect at that time shall be collected. ��, The 1-emainder of the water and sewer hookup fees shall be paid with the building pei7nit at flle rate in effect at that time. GRADING & EROSION CONTROL Sui-face water cui•rently drains from the back to the front of the property. The developer proposes grading on Parcel 1; Parcel2 with the existing hoine will not be altered. The developer will install a private storm sewer system on the Parcel 1 and grade the property so that surface runoff will not leave the site. The proposed private stot-m sewer system will connect to the city stoi�n sewer in front of Parcel 1. A pluinbing perinit is required for the private storm sewer; the pluinbing inspector will inspect the connection to the city stonn sewer inanhole. There is evidence of high groundwater conditions in the area: 1. Infiltration into a sanitary sewer manhole in the area. The infiltration was abated with the 2013 str•eet project. 2. Site investigation perfor7ned in 1980 by Hakanson Andei•son Associates, Inc. (attached) indicated mottled soils on the property 18 inches below the surface. Mottled soils ai-e indicative of periodic soil saturation. 3. Site investigation perfoimed in 1981 by Subter�•anean Engineel•ing, Inc. (attached) u7dicating presence of water during borehole drilling, rising to 2.6 feet below the ground surface. 4. Site investigation perfoi-�ned by Interstate Geotechnical Engineering, Inc on October 25, 2014. On Parcel 1 the proposed home style as required by Gity Code Section 18-40 (4) 2 (iii) is a slab- on-g7•ade home. Based on Interstate Geotechnical Engineering's observations, the groundwater elevation is 1.8 feet below the ground elevation of the soil boring. The developer must verify the surface elevation of the boring location to determine the elevation of the gi�oundwater; the lowest flooi•must be miiumum three feet above that elevation per City Code Section 18-40 (4) 2 (i). Interstate Geotechnical Engineerulg recommendations include removal of some of the material found on the site and placement of controlled fi11. On Noveinber 13, 2014 Interstate Geotechnical Engineering provided a follow-up letter with a professional opinion that the gt•oundwater elevation will retur�l to its original level after the soil con•ections are completed on the lot. Todd Gerhardt 2061 West 65th Street Metes & Bounds Subdivision '`�� n�SJune 8,2015 Page6of12 PARKS AND RECREATION The proposed subdivision is located within an area that is in the municipal park seivice boundaries of Pheasant Hill Pai-k and the Minnetonka Middle School West Campus. The propei�ty has access to the city's comprehensive ti•ail system located on Galpin Bouleval•d. In lieu of parkland dedication or trail construction, the development shall pay full park fees in foi•ce for the one new lot at the time of subdivision appi•oval. Pa��ks fees foi-2014 are $5,800.00 per sulgle-family lot. LANDSCAPING AND TREE PRESERVATION The applicant did not submit tree canopy covei•age and preservation calculations. Estimated calculations are as follows: �� Total upland area(excluding wetlands).....................30,324 SF Baseline canopy coverage..........................................26% or 8,160 SF Minimum canopy coverage allowed..........................30% or 9,097 SF Proposed tree preservation.........................................25% or 7,720 SF The applicant does not meet minimum canopy coverage allowed; therefore, the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings: Difference in canopy coverage ..................................1,377 SF Multiplier...................................................................1.2 Total replacement.......................................................1,652 SF Total number of trees to be planted ...........................1 tree The total number of trees requii•ed for the developinent is one.

A summary of my findings together with boring logs and my conclusions and recommendations are presented in the enclosed report. I found, as you already have been briefed, more than usual problems with the site. Thez-e is a total of 53/4' & 6'/4'at the locations of Boring 1 &Probe lA,respectively, of unsuitable soil in the form of topsoil fill, general and varying fill, and buried original humus. Below at first is a low sand content lean clay,generally dark in color, saturated,very soft to soft(w/depth). It is "normally consolidated99 (consolidated enough to only support its own weight, not additional weight of fill soils or structures above). The overburdening fill has not been inplace long enough to force further consolidation. The moisture content test in this material indicated nearly 42%, high for a lean clay. This material extends only from 53/4° to 7' in " Boring 1, but from 6'/4`to 83/2` in Probe lA. The first 9" of this material in Probe lA is ve�y soft and is a borderline marl material. All of the aforementioned materials are unsuitable for structure support should be removed. I do acknowledge that excavators are often reluctant to excavate further once the buried organic soil is cleared, so understandings should be inplace at the time of gathering bids. Base soil below at first is a lean clay, a little sandy, dark gray, saturated, rather soft to medium. It has inclusions of a poorly graded (biased finer grained) sand with a few fines, also dark gray, saturated,loose to firm.Deepest soil,commencing at 11'in Boring l,is a lean clay, rather sandy, dark gray, low gravel content, medium. Theses materials are glacial till. The sand inclusions in the upper portion are glacial outwash. All of these base mineral soils are suitable for residential construction,with conditions. Refusal to auger advancement was not encountered by boring termination depth of 23', indicating lack of bedrock to this level. Very importantly, groundwater was found in the main Boring at 1.8' (elev 96'/4±). It is aquifer groundwater, but marginally so, It appears to be contained primarily in the sand inclusions at 7'+. But it also is corriing from the upper soft and very soft clay,possibly from N�-,i�_i:.; �, . ��. � Mr James Rudos - 25 October 2014 Page 2 the lower organic soiL Proper construction on the site (removing the softer lean clay, promoting good site drainage) will mitigate some of this. 'Thus, water found presently can be regarded as a maximum levela Slab grade of the proposed residence should be set in accordance vvith City requirements utilizing this leveL I recommend complete removal of all unsuitable soil which is likely to be the fill and buried organic soil as encountered plus the overly soft clay found in both the boring and probe. While this amounts only to another 1'/4' in the vicinity of Boring l, it is another 2'+ in the vicinity of Probe lA. As indicated, excavators may be reluctant to excavate below organic soil level, but it is necessary(see longer discussion in the report). It is so important that full time inspection of the excavation by a soils engineer may be necessary. Of course, other zones of unsuitable soil not represented by the boring and probe could still be encountered due to the nature of small volume random sampling. Any other depths or zones of unsuitable soil should be removed as well. You could lo�ver footings somewhat so that you have to provide less oversizing and not stray onto the neighbor's property. But footings here should not be lowered so much as to rest directly upon the suitable base soil as it is only marginally suitable. You need a little fill (2' is recommended) to spread footing loads out with depth. Footings may be generally designed allowing the usual 2000 psf foundation bearing capacity, which will likely result in normal strip or pad footings. Special attention is again drawn to the advisory that excavations be examined by the Soils Engineer to verify soil boring results and to document adequacy of site preparation. Again this is very important as how much soft/very soft clay must be removed will require a high degree of field judgment. Fill, as used, should be tested for compaction adequacy. Soil correction should not be abated below slabs in any manner (ie, do not let the excavator try ta "trench around" slab areas). Thank you for the opportunity to have been of service. If you have any questions on this, or if I can be of assistance in any additional capacity, do not hesitate to contact me at your convenience.

Dear Bernie: � At your request percolation testing was performed at your lot located at part of the Southwest 1/4 of the Northwest 1/4 of Section 3 Township 116 North Range 23 West in Carver County, Minnesota. Standard methods of percolation testing were employed. Elevations are relative to an assumed elevation of 100.0' based at the top of the hydrant at the northeast property corner (see enclosed sketch) . This report includes: , � _ 1. �oil boring logs 2. Percolation test results 3. Testhole location sketch and systein configuration diagram 4. Septic system design specifications 5. Discussion and recommendations. The soil boring logs show sandy loam to sandy clay loam surface materials overlie heavier and firmer clay loam materials at depth. Significant soil mottling begins at about 1.5 feet depth at both boreholes. Soil mottles (spots of contrasting colorj are accepted indicators of periodic saturation in soils. Soil gleying begins at about 4.0 feet depth at both boreholes. Gleying (dull gray soil color) forms in soils which are saturated and in a chemically reduced condition for long periods of time. Because the Chanhassen sewage ordinance requires three (3.0) feet elevation difference between the bottom of standard sewage absorption trenches and the water table or soil mottling, the site is unsuited for installa- tion of a conv�ntional trench type septic system. An alternative means of sewage disposal, such as the mound (also known as the berm) system9 is recommended. The percolation test results (below) show that measured percolation rates are f_aster than the 120 minute per inch minimum rate for mound systems. Soil te�:ture at Hole Elevation Depth(inches) bottom of hole Percolation rate (min/in) ��l 98.1 24 Silty clay loam 3.0 f k �= � �,�F ;F �; p��:�"�c._� . .. . �l2 97.9 28 Sandy loam to sandy 2.1 clay loam �� f' , � 1�iSl "l��' �Jr_: �,� �f:�,� _,� .. ia a vi�fil"aljr'3,;+.3�: civil • municipal • planning • soils � land surveying G � Mr. Bernard Benz - 2 - September 2, 1980 Measured percolation rates are somewhat rapid for the soil material in which , the percolation tests were run. The design of the mound is based on a per- colation rate of 30-60 minutes per inch which is a typical rate for permeable clay loam soils. �, �( The minimum rockbed area for the mound is based on estimated sewage flow from a three bedroom house, 450 gallons per day9and the design infiltration rate of the medium sand fill material, 1.2 gallons per square font per day. ' ti 450 gallon/day -: 1.2 gallon/ft2/day = 375 ft2 ` �ao rock beds, each 10 feet wide by 20 feet long, provid�: tl�e needed area. The required basal area of the mound is based on the des��gn infiltration rate for a soil with a percolation rate of 30 to 60 minutes per inch, or 0.74 gallons per square foot per day. ' 450 gallon/day j 0.74 gallon/ft2/day = 608 ft2 , With 3 to 1 sideslopes and 1.5 feet of inedium sand fill beneath the rock beds, the basal area of the mound is 1,845 square feet; so sufficient infiltration area is provided by the design. The pressure distribution system consists of Schedule 40 PVC pipe. The supply pipe is 2i�inch inside diameter pipe. The supply pipe should slope back towards the pumpir�g chamber so that it drains after the mound is'�dosed. The laterals are 1.5 inch inside diameter pipe. The laterals should have 1/4 inch diameter holes drilled at a spacing of 3.0 feet. The laterals should be connected to the manifold so the holes point downwards into the rock. The distal ends of the laterals should be capped. Also, the last hole in each lateral should be drilled horizontally in the end cap near the crown of the pipe to facilitate air venting. A submersible effluent pump capable of delivering at least 34 gallons per minute at a total dynamic head of at least 13.7 feet should be selected. Headlosses are calculated as follow; 1. Elevation headloss of 7.5 feet between top of mound (elevation 100.5) and pump discharge (approximate elevation 93.0) 2. Friction headloss of 1.2 feet in 50 feet of supply pipe (2.4 feet loss per 100 feet of 2 inch I.D. plastic pipe) and 3. Five (5.0) feet to account for losses in distribution network. If elevations or distances are changed, headloss should be recalculated. The sole purpose of soils data contained herein is evaltation of soil suitability for on-site absorption of septic tank effluent at the test site. Although soil a Mr. Bernard Benz - 3 - September 2, 1980 texture and horizonation and ground water elevation data may be helpful for the setting of basement elevations at this site, we cannot warrant any such interpretations or the use of this data for other purpos�s. � ;; If you have any questions regarding information contained in this report, please feel free to call me.

MIN�NEAP�LIS, MINN. �,�X , �� 3 � � related �o the Des �.�oines ice lobe of the Wisconsin glaciation. During post-glacial times, a surface layer of topsoil has formed. According to i�formation published by the State of Minnesota Geological Sua°vey , th� uppermost bedrock stratum under this site is believed to be dolomitic limestone of the Prairie du Chien formation. There is an area of dumped fi11 just south of Borehole ; . SOIL CONDITIONS Only two basic soil types were encountered in our inves tigation , T{�ese are : topsoil ; and Des Moines clayey glacial till . Topsoil A surface layer of topsoil ,ranging in thickness from ' 1 .5 ° to 2 ' , occurs at our test hole locations . The topsoil consists of black organic silty and sandy cloy . It is in a soft condition, with standard penetration test values of 2 an 4 blows per foot . It is overlain by a thin layer of brown silty clay fill at Borehole 2 , The topsoil is unsuitable for foundation or floor slab support , or as a subgrade below a povement . . Water Modified Clayey Glacial Till The topsoil is underlain by a .major stratum of clayey gl�cial till . The uppermost 3 to 6 feet of the soil stratum has been modffied by alluvial action, and consist� of a mixture of grey anci brown silty clay , clayey silt and clayey ' . sand with random lenses of sond , :,�;;,... SU�`.I'.�+'R.R,AI`T�' 1�N ";,,�, I t - ENGINEERII�TG INC. n x MINNEAPOLIS, MI NI�T. ` 4 F The upper mixed glacial till has a soft to stiff consistency, with standard penetration test values ranging from 2 to 8 blows per foot . This soil layer has low load bearing capacity and moderate compressibility. . Des Moines Clayey Glacial Till • Commencing at o depth of 4. 6 ' to 8 ' below present ground surface, and extending beyoncJ the terminal depths of our borings, is a dark grey sandy clay with traces of gravel , � and random thin lenses of f� ne sand . Standard penetration test resistances within the dark grey clay vary from 5 to 13 blows per faot , representative of a stiff to tough consistency . • . This soil has moderate load-bearing capacity and low compressibility, and is a good foundation subsoil . GROUND WATER CONDITIONS Free ground water was observed in both boreholes, at a depth of 13' below present ground �urface shortly after compl ' � drilling . The water then slowly rose to a dept� of 2 . 6 ' below present ground surface, corresponding to �u.a t�_.o 3 ' . There are a number of lakes in the vicinity of the site . Lake rAinnetonko and Galpin Lake to the north have average water elevations of 930 ' and 942 ' respectively. Lake Minnew�shta to the west has an average water elevation of 944 . Ghristmas Lake to the northeast has an average water elevatio e of 932 ' , and Lake Lucy to the southeast has on average water elevatfon of 956 ' . ��"r�� SUBT�RRANEAI� �� ;� ENGINEERING INC. ' n x MIIVIVEAPOI,IS, MIN11oTT. x . 5 A smaller lake known as Harrison Lake, to the south, has an average water elevation of less than 1000 ' . " An analysis of this information indicated that the observed watex- levels in the soil borings represents perched graund water conditions, wherein the water is retarded from further downward percolation by relatively i.mpervious clay soils below . Thus, even though some seepage could potentially occur � in excavations extending deeper than 3 f.eet, the volume of '�, such seepage water would be small, and could be handled by � conventional pumping . DEVELOPAqENT PLANS , , It is proposed to build a single family dwelling along with an attached garage at this �.ot . The proposed hause is a 4-level , spYit-level home. The major portion of the house is a slab-on-grade structure vrith only a relatively shallow sub- grade crawl space level below the family room. The buildin will have masonry foundation walls to outside grade level, wi I wood frame construction above . Stsuctural loads on the foot- ings of such a building are relatively light . Lowest design floor level is approximately at existing ground levela APJALYSI S AND RECOMI�ENDATIONS ihe stiff to tough clayey glacial till soils underlyin this site are competent foundation svbsoils for the proposed residential structure . :��'''�� SUBTER�AI`TEAN ��.� - ENGII�EERING INC. �: � ,� IVIIN�NEAPOLIS, MINN. . '. � ` All obviously organic topsoil and any overlying existing fill should be stripped and removed from the buildin and pavement areas . In addition, it is recommended that the upper soft clay zone should be subcut in the proposed buildin area, and should be replaced with approved compacted sand #'il Removal of topsoil and subcut af soft clay soils to a depth of 3 ' below grade at aur test hole locations is recommendedo Fill necessary to reach design grades should be an approved inorganic sand soil, free of any foreign material or , debris . It shou].d be spread in 6 to 8-inch maximum loose '', lifts and should be compacted to acnieve at least 93% �.�aximum �I Modified Proctor Dry Density, A. SoT ,p1. .D�1557 in general fill , � areas and 95% �.�odified Proctor Dz°y Density in the uppermost 2i feet below pavement areas . It appears that it would be necessary to place the lowest design floor ievel approximately li feet above present ground surface at our test hole locations� in order to provid a minicnum 4 ° separation between the floor slab and ground water levels observed in our borings as required by F.H.A. The building may then be supported upon conventional, relatively shallow apread footing foundation based on approve ' compacted sand fill . A net allowable soil bearing pressure of I500 pounds per square foot may be vsed f.or the footing design . � '`�� SUBTER,�,ANEAN S��';n�, ENGrINEERIIITG INC. n Yx MIIi�NEAPOLIS, MINN, ° . - -� / ° All perimeter footings in heated portions of the build ing areas must be a minimum of 3i feet below outside finished grade for frost pratection purposes . Perimeter footings in unheated portions such as the outside garage walls should be at least 4 feet be�ow outside grade . Continuous strip foot� ings under bearing walls should be at least 18 inches wide for proctical reasons . It is also recommended that a perimet : tile drain system should be installed around the footings to provide drainage from the sand fi31 . A convention�l flexible pavement design, consisting of a 5" compacted granular base course overlafn by a 2" hot-m ', bituminous wea.ring surface, may be �seci above the sand fill I surface in the driveway area . 'I GENERAL ' The soil conditions have been established at our test hole locatfons only. There are likely to be variations in conditions between and around the borings, and interpolation or extrapolation of the results is not warranted. During construction, all excavations, earthwork , fill p�.acement and compaction should be monitored and tested by r qualified soil �engineers We would be pleased to provide the necessary field engineering observation and testing services .

A summary of my findings ' together with boring logs and my conclusions and recommendations are presented in the enclosed report. I found, as you already have been briefed, more than usual problems with the site. There is a total of 53/4'&6'/4'at the locations of Boring 1 &Probe lA,respectively, of unsuitable soil in the form of topsoil fill, general and varying fill, and buried original humus. Below at first is a low sand content lean clay,generally dark in color,saturated,very soft to soft(w/depth). It is "normally consolidated" (consolidated enough to only support its own weight, not additional weight of fill soils or structures above). The overburdening fill has not been inplace long enough to force further consolidation. The moisture content test in this material indicated nearly 42%, high for a lean clay. This material extends only from 53/4' to 7' in Boring 1, but from 6'/4'to 83/Z' in Probe lA. The first 9" of this material in Probe lA is very soft and is a borderline marl material.All of the aforementioned materials are unsuitable for structure support should be removed. I do acknowledge that excavators are often reluctant to excavate further once the buried organic soil is cleared, so understandings should be inplace at the time of gathering bids. Base soil below at first is a lean clay, a little sandy, dark gray, saturated, rather soft to medium. It has inclusions of a poorly graded (biased finer grained) sand with a few fines, also dark gray, saturated,loose to firm.Deepest soil,commencing at 11'in Boring 1,is a lean clay, rather sandy, dark gray, low gravel content, medium. Theses materials are glacial till. The sand inclusions in the upper portion are glacial outwash. All of these base mineral soils are suitable for residential construction,with conditions. Refusal to auger advancement was not encountered by boring termination depth of 23', indicating lack of bedrock to this level. Very importantly, groundwater was found in the main Boring at 1.8' (elev 96'/4±). It is aquifer groundwater, but marginally so. It appears to be contained primarily in the sand inclusions at 7'+. But it also is coming from the upper soft and very soft clay, possibly from : , ��'�'s�� ; . � Mr James Rudos 25 October 2014 Page 2 the lower organic soil. Proper construction on the site (removing the softer lean clay, promoting good site drainage) will mitigate some of this. Thus, water found presently can be regarded as a maximum level. Slab grade of the proposed residence should be set in accordance with City requirements utilizing this level. I recommend complete removal of all unsuitable soil which is likely to be the fill and buried organic soil as encountered plus the overly soft clay found in both the boring and probe. While this amounts only to another 1'/4' in the vicinity of Boring 1, it is another 2'+ in the vicinity of Probe lA. As indicated, excavators may be reluctant to excavate below organic soil level, but it is necessary(see longer discussion in the report). It is so important that full time inspection of the excavation by a soils engineer may be necessary. Of course, other zones of unsuitable soil not represented by the boring and probe could still be encountered due to the nature of small volume random sampling.Any other depths or zones of unsuitable soil should be removed as well. You could lower footings somewhat so that you have to provide less oversizing and not stray onto the neighbor's property. But footings here should not be lowered so much as to rest directly upon the suitable base soil as it is only marginally suitable. You need a little fill (2' is recommended) to spread footing loads out with depth. Footings may be generally designed allowing the usua12000 psf foundation bearing capacity, which will likely result in normal strip or pad footings. Special attention is again drawn to the advisory that excavations be examined by the Soils Engineer to verify soil boring results and to document adequacy of site preparation. Again this is very important as how much soft/very soft clay must be removed will require a high degree of field judgment. Fill, as used, should be tested for compaction adequacy. Soil correction should not be abated below slabs in any manner (ie, do not let the excavator try to "trench around" slab areas). Thank you for the opportunity to have been of service. If you have any questions on this, or if I can be of assistance in any additional capacity, do not hesitate to contact me at your convenience.

I think I spoke to you a couple of weeks ago on the phone about the lot next to mine and a proposed splitting of the lot. The property was recently sold to gentlemen who is "flipping" the property and it's come to my understandulg that he plans to split the lot into two parcels. The puipose of my letter is twofold. First, I want to inform you and/or whoever else might be working on this particulai-project that the lot in question has a pretty significant water problem. I'm surprised it was ever built on in the first place because the 1ot literally becomes a duck pond every spring when the snow melts and then again every tune we get any significant rainfall. It will get standing water more than ankle deep on both the western edge of the lot bordering inine and also on the south side of the lot. As I understand it there are springs underneath the ground and the water table is very high. This is coupled with the fact that the st�•eet is higher than the lot so the water has nowhere to drain. I tried to i-emedy this on my property by having a landscaping contractor install drain tile that ties into the catch basin in the culdesac. Unfortunately the lot in question next to me has an even larger drainage problem so it still iinpacts my propel�ty. Second, and more importantly, I want to be sure that if the lot is indeed approved to split and a new home is built that the proper steps are taken to ensure that any watershed does not impact my lot further. If any grading is done to build a new structure I wailt to be sure that it is not done in such a way that siinply moves the water problem from that lot on to mine. Hopefully whoever buys the property does their due diligence and has a percolation test done because if not I think they might end up being suiprised. Thanks in advance for your consideration regarding this inatter. If you or anyone has any questions I can be reached at 612-385-1329.

AI-Jaff, Sharmeen ' From: judy ashenbach [jashenbach@hotmail.com] ', Sent: Wednesday, October 29, 2014 11:16 AM To: AI-Jaff, Sharmeen Subject: To The Honorable Mayer& City Council Members This letter is to let you know of our concerns regarding the development of another lot at the property next door to us; 2061 West 65th Street. When we purchased out home in 1975, we were told that lot was not a buildable lot and would not be developed because of stream and wet land. When Mr. & Mrs. Benz built there home this forced the water our way and we had to add additional drainage to our home. When they built, I watch the slab of their home being laid in water. The side of their lot that they built on is the driest part of that property. To add another home on that lot would mean more water problems for this street and home owners. I remember when city sewer was installed and the city had to pump water from under the street for several weeks before installing sewer. Please take our concerns to all concerned. Thank you for your service and thank you for taking the time to serve us and the City of Chanhassen. �incerely, Bill and Judy Ashenbach 2041 West 75th Street Chanhassen, MN Phone 952-474-6821 jashenbach @Hotmail.com 1 �
