I L I have reviewed the documents that were sent over to us and spoke with George about some plant options we would suggest for the slope. Below are a few I'd suggest: Red-Osier Dogwood (shrub) -cornus stolonifera Ninebark (shrub)-physocarpus capitatus Snowberry (shrub) -sympthoricarpos a/bus GroLow Sumac (groundcover) -rhus aromatica Crown Vetch (groundcover)-coronilla varia Allium (native wildflower) -allium stellatum Yarrow (native wildflower) -achillea millefolium Blue Rug Juniper (low growing evergreen) -juniperus horizontalis 'Wiltonii' RECEIV ED APR 1 920'7 CllY OF ORONO There a quite a few options available but these are the few I suggest that are easy to get and seem to do well in our area. I tried to give a variety of both shrubs, wildflower, and groundcover that all do well in a very sunny climate. Not only is having a variety nice aesthetically , but it bas it's benefits with erosion as well . Having the variety of sizes will do a good job of breaking up/slowing down rainfall as it falls and hits the slope which in turn minimizes erosion during a rainfall event. 1 #3939 ;a _6JX CANNED DRAINAG~o,den-, EA MAP AR 96974X 9 6B.77 X X968.70 9 69.24X 969.42X X969 .5B 970-- --;~~GRAD£ 12"-18" HIGH BERM X969 .79 12• YARD DRAIN INLET TOP=967.8 --- - X96B.54 "-'-_----_o_ 6 7 ? 2 X 9c X96l X96B.9 7 X96B .76 SCANNED 1S --~ To NW inlet NW Depression 2S --~ To SE inlet SW Depression Routing Diagram for 160478 HydroCAD Prepared by Microsoft , Printed 6/1/2017 HydroCAD® 10 .00-20 s/n 03113 © 2017 HydroCAD Software Solutions LLC SCI\NNED 6,, 7 7 ') l i L 160478 HydroCAD MSE 24-hr 3 10-Year Rainfal/=4.26" Prepared by Microsoft Printed 6/1/2017 HydroCAD® 10.00-20 sin 03113 © 2017 HydroCAD Software Solutions LLC Page 2 Summary for Subcatchment 15: To NW inlet Runoff = 0.29 cfs @ 12.12 hrs, Volume= 0.012 af, Depth> 1.85" Runoff by SCS TR-20 method, UH=SCS, Weighted-CN, Time Span= 5.00-20.00 hrs, dt= 0.05 hrs MSE 24-hr 3 10-Year Rainfall=4.26" Area (ac) CN Adj Description 0.010 0.070 0.080 0.070 0 .010 0.010 Tc Length (min) (feet) 5.0 Runoff = 98 Unconnected pavement, HSG C 74 >75% Grass cover, Good HSG C 77 76 Weighted Average, UI Adjusted 87.50% Pervious Area 12.50% Impervious Area 100.00% Unconnected Slope Velocity Capacity Description (ft/ft) (ft/sec) ( cfs) Direct Entry, Summary for Subcatchment 25: To SE inlet 0.34 cfs @ 12.12 hrs, Volume= 0.015 af, Depth> 1.78" Runoff by SCS TR-20 method, UH=SCS, Weighted-CN, Time Span= 5.00-20.00 hrs, dt= 0.05 hrs MSE 24-hr 3 10-Year Rainfall=4.26" Area (ac) CN Adj Description 0.010 0.090 0.100 0.090 0.010 0.010 98 Unconnected pavement, HSG C 74 >75% Grass cover, Good HSG C 76 75 Weighted Average, UI Adjusted 90.00% Pervious Area 10.00% Impervious Area 100.00% Unconnected Tc Length Slope Velocity Capacity Description (min) (feet) (ft/ft) (ft/sec) (cfs) 5.0 Direct Entry, Summary for Pond 3P: NW Depression Inflow Area= 0.080 ac, 12.50% Impervious, Inflow Depth> 1.85" for 10-Year event Inflow = 0.29 cfs@ 12.12 hrs, Volume= 0.012 af Outflow = 0.28 cfs @ 12.14 hrs, Volume= 0.012 af, Atten= 0%, Lag= 0.9 min Primary = 0.28cfs@ 12.14hrs, Volume= 0.012af Routing by Stor-lnd method, Time Span= 5.00-20.00 hrs, dt= 0.05 hrs Peak Elev= 968.1 O' @ 12.13 hrs Surf.Area= 68 sf Storage= 9 cf Plug-Flow detention time= 0.4 min calculated for 0.012 af (100% of inflow) Center-of-Mass det. time= 0.4 min ( 788.6 -788.2 ) .,ANNED 677 2 160478 Hyd roCAD Prepared by Microsoft MSE 24-hr 3 10-Year Rainfal/=4 .26" Printed 6/1/2017 HydroCAD® 10.00-20 s/n 03113 © 2017 HydroCAD Software Solutions LLC Volume Invert Avail.Storage Storage Description #1 Elevation (feet) 967.80' Surf.Area (sq-ft) 137 cf Custom Stage Data (PrismaticJ..isted below (Recalc) Inc.Store (cubic-feet) 0 4 134 Cum.Store (cubic-feet) 967.80 968.00 968 .80 Device #1 #2 Routing Device 2 Primary 0 35 300 0 4 137 Invert Outlet Devices 967.80' 0.4" x 3.0" Horiz.

(Final Grade) is preparing to reconstruct the failed slope at 2807 Casco Point Road in Orono, Minnesota. We understand that Barr Engineering previously evaluated the slope failure and presented the owner with several different design options to repair the slope failure. Final Grade retained Haugo GeoTechnical Services to perform a geotechnical exploration to evaluate the suitability of site soil and groundwater conditions and provide our opinion on the proposed slope reconstruction at the site. 1.2 Purpose The purpose of this geotechnical exploration was to characterize subsurface soil and groundwater conditions and provide our opinion on the proposed slope reconstruction at the site. 1.3 Site Description The project site is located at 2807 Casco Point Road in Orono, MN. The site currently contains one residential home that is located about 55 feet northeast of the crest (top) of an existing slope along Lake Minnetonka. TI1e house area and backyard of the project site is relatively flat with the surface elevations at the soil boring locations ranging from about 970 feet to 9691/2 feel The slope is relatively steep and is indicated at about 40 degrees on the Barr Engineering documents provided . The height of the slope from the crest to Lake Minnetonka is about 30 feet. The slope face generally contains small trees and brush with an existing stairway to Lake Minnetonka. Portions of the slope face failed during a period of heavy rain in June 2014. The slope failure was not repaired and portions were covered with plastic sheeting. 1.4 Scope of Services Our services were performed in accordance with the Haugo GeoTechnical Services, LLC proposal 16-0978 dated November 15, 2016. Our scope of services was performed under the terms of our General Conditions and limited to the following tasks: • Completing two (2) standard penetration test soil borings and extending each to a nominal depth of 40 feet. • Recording GPS coordinates of the soil boring locations and elevations. • Visually /manually classifying the samples recovered from the soil borings. • Performing laboratory tests on selected samples. 1 SCANNED 67 "?') ( L A field log of each boring was prepared by the HGJ'S drill crew. The logs contained visual classifications of the soil materials encountered during drilling, as well as the driller's interpretation of the subsurface conditions between samples and water . observation notes. The final boring logs included with this report represent an interpretation of the field logs and include modifications based on visual/ manual method observation of the samples. The soil boring logs, general terminology for soil description and identification, and classification of soils for engineering purposes are also included in the appendix. The soil boring logs identify and describe the materials encountered, the relative density or consistency based on the Standard Penetration resistance (N-value, "blows per foot") and groundwater observations. The strata changes were inferred from the changes in the samples and auger cuttings. The depths shown as changes between strata are only approximate. The changes are likely transitions, variations can occur beyond the location of the boring . 3.0 RESULTS 3.1 Soil Conditions The soil borings encountered about 1 foot of topsoil at the surface. The topsoil consisted of sandy lean day that was black in color. Beneath the topsoil, the borings encountered native alluvial lean clay soils that extended to around 4 feet below the ground surface. Penetration resistance values (N-values), shown as blows per foot (bpf) on the boring logs, of 8 blows per foot (bpf) were recorded in the lean clays which indicate a medium consistency . Underlying the topsoil and alluvial clay soils, the soil borings encountered glacial till soils that extended to the boring termination depths of about 40 feet . The glacial till soils consisted mainly of clayey sand, with upper layers of sandy lean clays and lean clays encountered at boring SB-1 . N-values of 10 to 26 bpf were recorded in the glacial till soils. These values indicate the clayey sands had a medium dense relative density with upper loose zones while the sandy lean days /lean days had a stiff consistency. 3.2 Groundwater Groundwater was encountered in both soil borings after drilling between depths of about 31 1/i to 34 feet which correspond to elevations of about 936 to 938. Water levels were measured on the dates as noted on the boring logs and the period of water level observations was relatively short. Given the cohesive nature of the glacial till soils encountered, it is likely that insufficient time was available for possible perched groundwater to seep into the bore hole and rise to its hydrostatic level. The Minnesota DNR reports the Ordinary High Water Level (OHW) of Lake Minnetonka to be around an elevation of 929 112 feet . 3 SCANNED ·6 7j-'"?.( ?) £~ Groundwater monito1ing wells or piezometers would be required to more accurately determine water levels. Seasonal and annual fluctuations in groundwater levels should be expected. 3.3 Laboratory Tests Laboratory moisture content and percent passing the Number 200 sieve (P-200 content) tests were performed on selected samples recovered from the soil borings . A summary of the laboratory testing is presented in the Table 1 below. The moisture contents of the samples are also provided on the soil boring logs opposite the sample tested . a e .

The cohesive soils will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines, while the granular soils will generally classify as Type C soils . 4 SCANNED 6 7 7 !) , j L , APPENDIX SGAl -,, {. = Approximate Soil Boring location GPS Boring Locations Boring Number Elevation Northing Easting (US Survey Feet) Coordinate Coordinate SB-1 970.0 149485.379 438364.937 SB-2 969.3 149530.864 438303.037 Referencing Minnesota County Coordinates Basis -Hennepin County (GEOID09 Conus model) Haugo GeoTechnical Services. 2825 Cedar Avenue S.
