City Council approval requires a majority vote of City Council present. On November 24, 2014 the Chanhassen City Council approved a metes and bounds subdivision dividing Lot 3, Block 1, Moline's Addition into Parcels 1 and 2, Block 1, subject to conditions. One of the conditions of approval was that the applicant was required to install the sewer and water service to the vacant property (Parcel 2) and submit a $10,000 escrow to ensure that the work was complete and the street properly restored. Subsequent to the November 24, 2014 meeting, the applicant requested that this condition be removed so that the person(s) purchasing and building on the property would be responsible for the installation of the sewer and water service, including the necessary road repair to West 65d' Street. The staff report has been edited and conditions of approval amended to reflect this change. All new information will appear in bold. ATTACHMENT 1. Resolution. 2.

Amends the conditions of approval to the metes and bounds subdivision for property located at 2061 West 651h Street (legally described as Lot 3, Block 2, Moline's Addition, Carver County, Minnesota) as follows: a. Metes and bounds subdivision Parcel 1 and Parcel l with the following conditions: Building The existing structure on proposed Parcel 2 must be provided with sanitary sewer connection — permit required. 2. Proposed Parcel 1 must be provided with separate sewer and water services (permit required) before a building permit is issued. Engineering The City Attorney shall draft and the developer shall execute a "Grant of Permanent Easement for Public Drainage and Utility Purposes" document. This document shall be recorded with the metes and bounds subdivision. 2. A roadway, 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. This easement shall be recorded with the metes and bounds subdivision. 3. Prior to recording the subdivision the developer shall pay the $45 GIS fee: $25 (subdivision) plus $10/parcel. 4. Sewer and water hookup charges are due for *met Parcel 1, a portion of which shall be collected before the metes and bounds subdivision is recorded: Water: 1 unit x $1,957/unit = $1,957 Sewer: 1 unit x $677/unit = $677 The remainder of the sewer and water hookup charges for Parcel 1 shall be collected with the building permit. 5. If the final subdivision submittals are received after 2015, all fees shall be recalculated based on the rates in effect at that time. 6.

On Parcel 1, the proposed home style as required by City Code Section 18-40 (4) 2 (iii) is a slab -on -grade 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 groundwater; the lowest floor must be minimum three feet above that elevation per City Code Section 18-40 (4) 2 (i). 8. Before a building permit is issued for Parcel 1, the water service and sanitary sewer service must be installed. The sanitary sewer is within West 65s' 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 requirements. 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 9.

City Council approval requires a majority vote of City Council present. EXECUTIVE SUMMARY The applicant is requesting metes and bounds subdivision approval to divide 30,324 square feet into two lots. City council may approve a metes and bounds subdivision of a lot into two lots inside the urban services area if both resulting lots meet the minimum requirements of the zoning ordinance and abut an existing public street, pursuant to Section 18-37 (b) of the Chanhassen City Code. PROPOSAL SUMMARY Request for a metes and bounds subdivision of 30,324 square feet (0.69 acres) into two (2) lots on property zoned Single -Family Residential (RSF) and legally described as Lot 3, Block 2, Moline's Addition (2061 West 65"' Street).

The proposed subdivision meets city ordinance requirements and staff is recommending approval subject to the conditions of this staff report. The Moline's Addition plat was filed with Carver County on December 29, 1969. The existing home was built in 1981. No other records exist. APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 20, Article XII, "RSF" Single -Family Residential District LAND USE: Residential Low Density (1.2 — 4.0 units per net acre) SUBDIVISION REVIEW The applicant is requesting a metes and bounds subdivision creating two lots. The net density of the development is 2.8 units per acre. Both parcels meet all the lot area, width and depth requirements. Parcel 2, which contains a single-family home, will have a total hard surface coverage of 24%. The city code allows up to 25%. The existing structure meets all required setback requirements.

The City Attorney shall draft and the developer shall execute a "Grant of Permanent Easement for Public Drainage and Utility Purposes" document. This document shall be recorded with the metes and bounds subdivision. Todd Gerhardt 2061 West 65"' Street Metes & Bounds Subdivision r"_ 6—, 241-55June 8, 2015 Page 4 of 12 A roadway, 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. Prior to recording the subdivision the developer shall pay the $45 GIS fee: $25 (subdivision) plus $10/parcel. STREETS The proposed subdivision is adjacent to West 65a` Street, a 25 -foot wide public street within a 60 -foot wide right of way without curb and gutter. This street was constructed in 1979 and was overlaid in 2013. The current standard for 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 65a' Street that provides service to the existing home.

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 sanitary sewer service must be installed. The sanitary sewer is within West 65' 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 requirements. 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 before the metes and bounds subdivision is recorded: Water: 1 unit x $1,886 $1,957/unit = $1,896 $1,957 Sewer: 1 unit x $664 $677/unit = $664$677 Todd Gerhardt 2061 West 65"' Street Metes & Bounds Subdivision Nla ''.may 5June 8, 2015 Page 5of12 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 remainder of the water and sewer hookup fees shall be paid with the building permit at the rate in effect at that time. GRADING & EROSION CONTROL Surface water currently drains from the back to the front of the property. The developer proposes grading on Parcel 1; Parcel l with the existing home 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 storm sewer system will connect to the city storm sewer in front of Parcel 1. A plumbing permit is required for the private storm sewer; the plumbing inspector will inspect the connection to the city storm sewer manhole. There is evidence of high groundwater conditions in the area: Infiltration into a sanitary sewer manhole in the area. The infiltration was abated with the 2013 street project. 2. Site investigation performed in 1980 by Hakanson Anderson Associates, Inc. (attached) indicated mottled soils on the property 18 inches below the surface. Mottled soils are indicative of periodic soil saturation. 3. Site investigation performed in 1981 by Subterranean Engineering, Inc. (attached) indicating presence of water during borehole drilling, rising to 2.6 feet below the ground surface. 4. Site investigation performed by Interstate Geotechnical Engineering, Inc on October 25, 2014. On Parcel 1 the proposed home style as required by City Code Section 18-40 (4) 2 (iii) is a slab - on -grade 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 groundwater; the lowest floor must be minimum three feet above that elevation per City Code Section 18-40 (4) 2 (i). Interstate Geotechnical Engineering recommendations include removal of some of the material found on the site and placement of controlled fill. On November 13, 2014 Interstate Geotechnical Engineering provided a follow-up letter with a professional opinion that the groundwater elevation will return to its original level after the soil corrections are completed on the lot. Todd Gerhardt 2061 West 65th Street Metes & Bounds Subdivision "l^^26,24' SJune 8, 2015 Page 6 of 12 PARKS AND RECREATION The proposed subdivision is located within an area that is in the municipal park service boundaries of Pheasant Hill Park and the Minnetonka Middle School West Campus. The property has access to the city's comprehensive trail system located on Galpin Boulevard. In lieu of parkland dedication or trail construction, the development shall pay full park fees in force for the one new lot at the time of subdivision approval. Parks fees for 2014 are $5,800.00 per single-family lot. LANDSCAPING AND TREE PRESERVATION The applicant did not submit tree canopy coverage 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 required for the development is one. There are no bufferyard requirements for this subdivision. MISCELLANEOUS A final grading plan and soils report must be submitted to the Inspections Division before building permits can be issued. Retaining walls over four feet high require a permit and must be designed by a professional engineer. Each lot must be provided with separate sewer and water services. COMPLIANCE TABLE Area (sq. ft.)

Corey have requested a subdivision of the property into two lots of 15,165 square feet and 15,159 square feet; and WHEREAS, the Chanhassen City Council held a public hearing on November 24, 2014, and found the plan consistent with the Chanhassen Comprehensive Plan and Zoning ordinance. NOW, THEREFORE, BE IT RESOLVED that the Chanhassen City Council hereby approves the metes and bounds subdivision of 2061 West 65`d Street (Planning Case #2014-30) for John J. and Kimberly E. Corey for property legally described as Lot 3, Block 2, Moline's Addition, Carver County, Minnesota, subject to the following conditions: Building The existing structure on proposed Parcel 2 must be provided with sanitary sewer connection — permit required. 2. Properties must be provided with separate sewer and water services. 3. Existing Subsurface Sewage Treatment Site on proposed Parcel 1 must be properly discontinued and abandoned — permit required. Engineering The City Attorney shall draft and the developer shall execute a "Grant of Permanent Easement for Public Drainage and Utility Purposes" document. This document shall be recorded with the metes and bounds subdivision. 2. A roadway, 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. Prior to recording the subdivision the developer shall pay the $45 GIS fee: $25 (subdivision) plus $10/parcel. 4. Prior to recording the subdivision a $10,000 security must be provided to ensure that the street is restored. The security can be released when the city determines that the patch is in good condition after one freeze -thaw cycle. 5. Sewer and water hookup charges are due for the new lot, a portion of which shall be collected before the metes and bounds subdivision is recorded: Water: 1 unit x $1,886/unit = $1,886 Sewer: 1 unit x $664/unit = $664 6. If the final subdivision submittals are received after 2014, all fees shall be recalculated based on the rates in effect at that time. 7. The remaining 70% of the sanitary sewer and water hookup fees must be paid with the building permit at the rate in effect at that time. 8. A plumbing permit is required for the private storm sewer; the plumbing inspector will inspect the connection to the city storm sewer manhole. 9. On Parcel 1, the proposed home style as required by City Code Section 18-40 (4) 2 (iii) is a slab -on -grade 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 groundwater; the lowest floor must be minimum three feet above that elevation per City Code Section 18-40 (4) 2 (i).

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 5'/4'& 61/4 at the locations of Boring 1 & Probe 1A, 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 61/4 to 83/2'in Probe 1A. 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 1 Pin 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 961/4±). 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 SCANNED 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 V/4 in the vicinity of Boring 1, it is another 2'+ in the vicinity of Probe IA. 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 maybe 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 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.

As you know, I investigated the lot last month and issued a report dated 25 October 2014,1 found a total of T& 8'/2'of unsuitable soil at the locations of Boring I & Probe IA, respectively, in the form of topsoil fall, general and varying fill, buried original humus and overly soft clay or marl. First suitable base soil is a loose to firm sand or a soft to medium lean clay. I recommended removing these materials and placing controlled fill, noting that you will have to seriously control groundwater in the process. Regarding groundwater, I found it very high on this site - at a stabilized level of 1.8'. As I understand it, The City of Chanhassen has asked if this water level will change as a result of site correction. I used as a stabilized water level the 1.8' found a day after the hand auger phase was completed. I had encountered water while drilling and did achieve the base granular soil that first day. When I did the power auger phase, water was creeping up to nearly the same level a few hours later, so I felt that the 1.8' is valid. I believe that, when you correct this lot, controlling groundwater, and compacting fill, most likely granular, the groundwater will soon rebound to its original level - 1.8' as found in my boring. If you construct ordinary and good site drainage on your finished project, groundwater will not be affected by any artificial rrcharge the result of your activities. If you have any additional questions on this, or if I can be of assistance in any additional capacity, do not hesitate to contact me at your convenience.

Box 665 222 Monroe Street Mr. Bernard Benz 311 3rd Street Excelsior, Minnesota 55331 Re: Benz Percolation Dear Bernie: professional engineers and surveyors Anoka, Minnesota 55303 September 2, to -r 3 8 ZO(,f W 612/417-5860 � . �lrrlLaS' ZS 1 F 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. _ Joil boring logs 2. Percolation test results 3. Testhole location sketch and system 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 color) 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 conventional trench type septic system. An alternative means of sewage disposal, such as the mound (also known as the berm) system, is recommended. The percolation test results (below) show that measured percolation rates are faster than the 120 minute per inch minimum rate for mound systems.

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 day,,and the design infiltration rate of the medium sand fill material, 1.2 gallons per square foot per day. 450 gallon/day . 1.2 gallon/ft2/day - 375 ft2 Two rock beds, each 10 feet wide by 20 feet long, provi& the needed area. The required basal area of the mound is based on the design 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 = 0.74 gallon/ft2/day = 608 ft2 With 3 to 1 sideslopes and 1.5 feet of medium 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�R',inch inside diameter pipe. The supply pipe should slope back towards the pumpii+4g 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 evaluitionof soil suitability for on-site absorption of septic tank effluent at the test site. Although soil 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 purposes.

The purposes of our work were to determine the general soil and ground water conditions within the proposed building area, and to prepare a report of our findings, including comments on recommended foundation types, footing design and installation procedures, etc. PROCEDURE A total of two (2) soil test holes were drilled at locations designated by Mr. Cravens in the field. The field work was performed on June 22, 1981 using a truck -mounted CME -55 drill unit SOIL AND FOUNDATION ENGINEERING, FIELD LOADING TESTS, ROAD SUBGRADE INVESTIGATIONS, EARTHWORK CONTROL 8 PAVEMENT DESIGN, MATERIALS TESTING, OBSERVATION AND CONSULTATIONS The test holes were advanced with 3'4"i.d. x 7"o.d. continuous flight, hollow stem augers which act as a temporary casing to prevent collapse of the sides of the holes. Standard penetration tests were performed in advance of the auger tip at 2 to 5 foot intervals of depth, in accordance with procedures designated in A.S.T.M. D-1586. Periodic observations for group water levels in the boreholes were made while drilling and aft completion. All soil samples obtained were brought to our laborator for examination and classification. They will be retained for a period of at least 90 days from date of issue of this report, after which they will be discarded unless we are otherwise notified. Drawing No. 1 is a site plan showing the soil test hole locations in relation to the outline of the proposed house. Detailed soil descriptions along with a plot of the standard penetration test blows per foot are given on the Borehole Log sheet, Drawing No. 2. Following the regular written soil descriptions are capital letters in parentheses, which represent the appropriate group symbols of the Unified Soil Classificatior System. A chart explaining this system is appended. All elevations in this report are to geodetic datum, and were obtained using the bench mark noted on the site plan. SITE AND GEOLOGY The property under present study is located on the upper portion of a large hill south of Lake Minnetonka. Natural inorganic soil at the site consists mainly of clayey glacial tjI SUBTERRANEAN ENGINEERING INC. x xx MINNEAPOLIS, MINN. related to the Des Moines ice lobe of the Wisconsin glaciation. During post -glacial times, a surface layer of topsoil has formed. According to information published by the State of Minnesota Geological Survey, the uppermost bedrock stratum under this site is believed to be dolomitic limestone of the Prairie du Chien formation. There is an area of dumped fill just south of Borehole SOIL CONDITIONS Only two basic soil types were encountered in our inves tigation. These 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 clay. It is in a soft condition, with standard penetration test values of 2 a 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 pavement. Water Modified Clayey Glacial Till The topsoil is underlain by a.major stratum of clayey glacial till. The uppermost 3 to 6 feet of the soil stratum has been modified by alluvial action, and consists of a mixture of grey and brown silty clay, clayey silt and clayey sand with random lenses of sand. :. SUBTERRANEAN ENGINEERING INC. x x MINNEAPOLIS, MINN. 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 a depth of 4.6' to 8' below present ground surface, and extending beyond the terminal depths of our borings, is a dark grey sandy clay with traces of gravel, and random thin lenses of fine sand. Standard penetration test resistances within the dark grey clay vary from 5 to 13 blows per foot, 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 surface shortly after compl n drilling. The water then slowly rose to a deptf of 2.6' below present ground surface, corresponding to There are a number of lakes in the vicinity of the site. Lake Minnetonka and Galpin Lake to the north have average water elevations of 930' and 942' respectively. Lake Minnewashta to the west has an average water elevation of 944' Christmas Lake to the northeast has an average water elevatio of 932', and Lake Lucy to the southeast has an average water elevation of 956'.. �y SUBTERRANEAN ENGINEERING INC. x MINNEAPOLIS, MINN. 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 water levels in the soil borings represents perched ground water conditions, wherein the water is retarded from further downward percolation by relatively impervious clay soils below. Thus, even though some seepage could potentially occur in excavations extending deeper than 3 feet, the volume of such seepage water would be small, and could be handled by conventional pumping. DEVELOPMENT PLANS It is proposed to build a single family dwelling along with an attached garage at this lot. The proposed house is a 4 -level, split-level home. The major portion of the house is a slab -on -grade structure with only a relatively shallow sub - grade crawl space level below the family room. The buildi will have masonry foundation walls to outside grade level, wii wood frame construction above. Structural loads on the foot- ings of such a building are relatively light. Lowest design floor level is approximately at existing ground level. ANALYSIS AND RECOMMENDATIONS The stiff to tough clayey glacial till soils underlyinc this site are competent foundation subsoils for the proposed residential structure. SUBTERRANEAN ENGINEERING INC. MINNEAPOLIS, 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 fi7 Removal of topsoil and subcut of soft clay soils to a depth of 3' below grade at our test hole locations is recommended. Fill necessary to reach design grades should be on approved inorganic sand soil, free of any foreign material or debris. It should be spread in 6 to 8 -inch maximum loose lifts and should be compacted to achieve at least 93% Maximum Modified Proctor Dry Density, A.S.T.M..D-1557 in general fill areas and 95% Modified Proctor Dry Density in the uppermost 2' feet below pavement areas. It appears that it would be necessary to place the lowest design floor level approximately 14 feet above present ground surface at our test hole locations, in order to provid a minimum 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 1500 pounds per square foot may be used for the footing design. �, Mat' SUBTERRANEAN ENGINEERING INC. INNEAPOLIS, MINN. All perimeter footings in heated portions of the buil ing areas must be a minimum of 34 feet below outside finished grade for frost protection purposes. Perimeter footings in unheated portions such as the outside garage walls should be at least 4 feet below outside grade. Continuous strip foot- ings under bearing walls should be at least 18 inches wide for practical reasons. It is also recommended that a perime tile drain system should be installed around the footings to provide drainage from the sand fill. A conventional flexible pavement design, consisting of a 5" compacted granular base course overlain by a 2" hot -mi bituminous wearing surface, may be used above the sand fill surface in the driveway area. GENERAL The soil conditions have been established at our test hole locations 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 placement and compaction should be monitored and tested by a qualified soil engineer. 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 5'/4'& 61/4 at the locations of Boring 1 & Probe 1A, 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 5'/4 to 7' in Boring 1, but from 6'/4 to 83/z in Probe IA. 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 1 Pin 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 SCANNED 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 V/4 in the vicinity of Boring 1, it is another 2'+ in the vicinity of Probe IA. 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 maybe 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 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 found a total of 7 & 8'/,'of unsuitable soil at the locations of Boring 1 & Probe IA, respectively, in the form of topsoil fill, general and varying fill, buried original humus and overly soft clay or marl. First suitable base soil is a loose to Stan sand or a soft to medium lean clay. I recommended removing these materials and placing controlled fill, noting that you will have to seriously control groundwater in the process. Regarding groundwater, I found it very high on this site - at a stabilized level of 1.8'. As I understand it, The City ofChanhassen has asked if this water level will change as a result of site correction. I used as a stabilized water level the 1.8' found a day after the hand auger phase was completed. I had encountered water while drilling and did achieve the base granular soil that first day. When I did the power auger phase, water was creeping up to nearly the same level a few hours later, so I felt that the 1.8' is valid. I believe that, when you correct this lot, controlling groundwater, and compacting fill, most likely granular, the groundwaterwill soon rebound to its original level - 1.8' as found in my boring. If you construct ordinary and good site drainage on your finished project, groundwater will not be affected by any artificial recharge the result of your activities. If you have any additional questions an 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 understanding that he plans to split the lot into two parcels. The purpose of my letter is twofold. First, I want to inform you and/or whoever else might be working on this particular 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 lot literally becomes a duck pond every spring when the snow melts and then again every time we get any significant rainfall. It will get standing water more than ankle deep on both the western edge of the lot bordering mine 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 street is higher than the lot so the water has nowhere to drain. I tried to remedy 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 impacts my property. 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 want to be sure that it is not done in such a way that simply 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 surprised. Thanks in advance for your consideration regarding this matter. If you or anyone has any questions I can be reached at 612-385-1329.

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.
