CALL TO ORDER and PLEDGE OF ALLEGIANCE     2. PUBLIC FORUM The public forum is intended to afford the public an opportunity to address concerns to the City Council. The public forum will be no longer than 30 minutes in length and each presenter will have no more than five (5) minutes to speak. Topics of discussion are restricted to City governmental topics rather than private or political agendas. Topics may be addressed at the public forum that are on the agenda. However, topics that are the subject of a public hearing are best addressed at the public hearing, not at public forum. Therefore, topics may not be addressed at public forum if: (I) the topic has been the subject of a public hearing before the City Council or any City Advisory Committee and the Council has not acted on the topic; or (ii) if the topic is the subject of a public hearing for which notice has been published in the City’s official newspaper, or a continued public hearing or public information hearing before the City Council or any City Advisory Committee. During public forum, a member of the public may request that the City Council consider removing an item from the Consent Agenda following the procedure set forth in Section 401.5. The City Council may discuss but will not take formal action on public forum presentations. Matters that are the subject of pending litigation are not appropriate for the forum.     3.

ADJOURNMENT      Lakefront Park Master Plan | City of Prior Lake | HKGi  1 | Page    MEMO Wednesday, Jan. 19, 2022 TO: Lakefront Park Advisory Committee FROM: Gabrielle Grinde, HKGi RE: Lakefront Park DRAFT Master Plan Concept Please review the attached Lakefront Park Draft Concept Plan. This concept was developed following public engagement input, two meetings with the Advisory Committee, and city staff input. The following elements and features are included in the concept. The highlighted numbers correspond with the legend on the concept graphic. Watzl’s Beach (1)  Public day slips are being brought back to the north side of the beach (6 slips)  A fishing pier is shown at the end of the new boat day slips  A new small restroom building is shown on the beach, vending machines will be included  There is space to accommodate a food truck at the beach during peak use times, with included electrical access; the food trucks would access the beach along the walking trails  A new road (2) and ADA parking stalls (3) will provide better access to the beach.  A new stairway (4) will provide direct access from the upper parking lot to the beach North Parking Area / Tennis courts  2 new Tennis courts (5) are placed at the top of the hill adjacent to the upper parking lot (location of current skate park); the new courts will be sheltered from wind by the surrounding trees  The existing trail connection from the north parking lot to Rutledge Street SE will be widened for emergency vehicle access  Convert large areas of turf grass/lawn to prairie grasses, primarily on slopes that are not conducive to other uses. Playground / Splash Pad  Replace existing playground with new adventure playground (6) built into the slope  Remove gazebo to allow room for splash pad  Construct a new splash pad (7), which is currently shown on the small size for a splash pad; we will include precedent images of different sizes of splash pads  Seating and shade for parents and caregivers around the splash pad and playground. Add a new picnic shelter between the playground and splash pad.  Pavilion (8) modifications: Lakefront Park Master Plan | City of Prior Lake | HKGi  2 | Page    o Alternative 1: Maintain Pavilion as is. Restrooms are only available to those who rent the pavilion for meetings or events. Construct a new restroom/changing room building near the splash pad and playground. o Alternative 2: Modify the existing pavilion to add on publicly accessible restrooms from the outside of the building that will serve the playground, splash pad, and other general park users. Skate Park and Basketball  Develop a new skate park (9) with bowl and high level features permanently located centrally in the park  Develop new basketball courts (10) centrally located in the park, one full court and two half courts  New road access (11) from the central area of the park to the east, with connection to Ridgemont Ave SE. Parallel parking is added along a portion of the road.  A new stormwater detention basin (12) is located between the parking lots in order to manage stormwater from the new road.  The southern most parking lot, centrally located in the park would be expanded (13) with a second drive aisle and two rows of parking stalls, which would more than double the parking stalls in that lot.  The existing baseball diamond will be removed and replaced with lawn open space that may be used for events or potentially a future amphitheater (14) or performance space.  Remove the existing picnic shelter near the baseball diamond. East Park / Winter Use Area  A new park building will be constructed along Ridgemont Ave SE, which will provide an outdoor patio space (15) to be used for both winter and summer gatherings with firepits and seating, and an indoor warming house (16) to support the sledding and ice skating/hockey uses at the park. This building could be used for the general public in the winter and rented out for events in the summer time.  The parking lot along Ridgemont Ave SE will be relocated to the north and expanded (17) to serve a larger recreation program.  Ice skating / hockey (18): o Alternative 1: A new ice skating ribbon will be constructed in place of the tennis courts and parking lot to provide a formal pleasure skating feature. o Alternative 2: One or two hockey rinks will be relocated from the bottom of the sledding hill to the top  The sledding hill will remain in place with a slight modification to the slope and direction of the hill due to the new road and slightly rerouted trails. Woodlands and Trails  Add a disc golf course along the edge of the woods  Trails through the woods: Include one main paved trail loop or spine through the woods, and transform the rest to natural surface. The natural surface trails would not be plowed. Consider winter trail uses -- cross country skiing, snowshoeing, etc. Lakefront Park Master Plan | City of Prior Lake | HKGi  3 | Page     Update the boardwalk across Lower Prior, potentially enhance to a bridge rather than a floating boardwalk. Add overlook in the middle of the bridge, to be used as a fishing/overlook area. Next Steps  Please provide your feedback by Jan. 24.  We will make revisions to the concept based on Advisory Committee feedback and present the draft concept to the City Council on Feb. 7th  The second phase on public engagement will be held in February and March to solicit input on priorities for implementation.  The Advisory Committee will meet one more time, in April, to review feedback to the concept plan and the draft Master Plan document.   Lakefront Park Master Plan | City of Prior Lake | HKGi  4 | Page    Precedent Images Splash Pad – Rosemount example ~3,800 SF Maple Grove Central Park Splashpad ~2,200 SF Lakefront Park Master Plan | City of Prior Lake | HKGi  5 | Page    Picnic plaza and small splash pad Slides built into the slope Lakefront Park Master Plan | City of Prior Lake | HKGi  6 | Page    Nature themed play equipment Nature themed play equipment Lakefront Park Master Plan | City of Prior Lake | HKGi  7 | Page    Adventure play- zipline Shade structures and picnic tables Lakefront Park Master Plan | City of Prior Lake | HKGi  8 | Page    Skatepark Stairway through woods Lakefront Park Master Plan | City of Prior Lake | HKGi  9 | Page    Ice skating loop Natural surface trail through woods Lakefront Park Master Plan | City of Prior Lake | HKGi  10 | Page    Wayfinding signage Disc golf course Lakefront Park Master Plan | City of Prior Lake | HKGi  11 | Page    Warming house / event building dual purpose Boardwalk / bridge LAKEFRONT PARK CONCEPT 1 2 5 4 6 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 7 8 9 10 11 12 13 14 18 20 19 17 16 153 LEGEND ALT 2: HOCKEY RINK Enhanced beach amenities (restroom building, beach canopies, picnic tables, fire pit) New road with drop off near beach Handicap parking Stairway connection to beach area Tennis courts Playground Splash pad Existing pavilion (possible exterior bathroom expansion) Skate park Basketball courts New road with parallel street parking Detention basin Expanded parking lot Possible amphitheater location Warming house patio Warming house Relocated, expanded parking lot Skating ribbon Disc golf Bridge with fishing pier/overlook Rutledge St S E Hope St SE AmphitheaterAmphitheater Sledding HillSledding Hill Community Community GardenGarden MemorialMemorial Kop BuildingKop Building VolleyballVolleyball Park ShelterPark Shelter Mitchell Cir SELakeview Cir SERidgemont Ave SEFranklin Trail SEFranklin Trail SEBounty St SE Crossandra St SE Gateway St SE 160th St SE Jordan Ave SEMemorial Trail SESt Paul AveOak St S E Minne s o t a S t S E Dakota S t S E Dakota S t S E D a k o t a S t S ECambridge Cir SEEagle Cr e e k A v e S E Eagle C r e e k A v e S E Grainwoo d Cir N E Grainwoo d Cir N EEau Claire Trail NECalmut Ave NEEau Claire Trail NE Colorado St SE Duluth Ave SEArcadia AveWest Ave SEWest Ave SEWest Ave SE Sunfish Trail SEQuincy St SE Bass St SE Birch Ave SELakeside Ave SELakeside Ave SEEvanstone Ave SEKop P k w y Main Ave SEErie Ave SEArcadia AveHsatings Ave SEBreezy Point Rd SEStefan Cir SERed Oaks Rd SE13 13 K o p P k wy C a m bridge Cir SE16 17 CHECK REGISTER FOR CITY OF PRIOR LAKE 1/8Page: 01/28/2022 09:44 AM User: Janet DB: Prior Lake CHECK DATE FROM 01/08/2022 -

EXECUTIVE SUMMARY Phase 2 of the Fish Point Road (CSAH 44 to TH 13) Reconstruction Project includes the reconstruction of Fish Point Road SE from 160th Street SE (CSAH 44) to MnDOT Trunk Highway 13 (TH 13). Phase 1 of the project was completed in 2021 and included the reconstruction of the local streets that access Fish Point Road SE in this area. These streets include: Hidden Oaks Circle SE, Timberview Street SE, Millers Circle SE, Glory Circle SE, Timber Trail SE, and Omega Trail SE. This feasibility report will cover Phase 2 of the Fish Point Road Reconstruction Project. The reconstruction of the Fish Point Road corridor and underlying utilities is identified in the City’s Capital Improvement Plan (CIP) for construction in 2023. Roadway reconstruction, consisting of removal of the existing bituminous pavement, subgrade correction, replacement of concrete curb and gutter, and new bituminous pavement is proposed for Fish Point Road from 160th Street SE (CSAH 44) to MnDOT Trunk Highway 13 (TH 13), which is approximately 3,480 feet (0.66 miles). The sidewalk along Fish Point Road SE is also proposed to be replaced with this project. Existing public retaining walls within the project area will be replaced in conjunction with the public improvements. A map showing the project location can be found on Figure 1 in Appendix A. Replacing portions of the City’s deteriorating utility infrastructure in conjunction with the proposed street improvements provides an opportunity to minimize the replacement costs and traffic disruptions associated with the work. Proposed utility improvements include the following: ▪ Installation of new watermain ▪ Replacement of hydrants, gate valves, and utility services ▪ Installation of new storm sewer to improve overall drainage and meet State Aid design standards along Fish Point Road ▪ Replacement of vitrified clay pipe (VCP) sanitary sewer pipe Traffic improvements are also proposed to Fish Point Road: ▪ Intersection improvements at Fish Point Road and TH 13 to facilitate the construction of dedicated turn lanes for northbound and southbound traffic onto TH 13 from northbound Fish Point Road, and a dedicated through lane for southbound traffic onto Fish Point Road from TH 13 ▪ Modification of ingress and egress points to Twin Oaks Middle School The proposed improvement cost for reconstructing Fish Point Road in 2023 is estimated to be $5,998,000.00. These estimates include a 10% contingency and 28% indirect costs. Funding for the project will be provided through assessments to benefiting properties, tax levy , State Aid funds, and various City funds. Reconstruction of Fish Point Road is scheduled to begin in the spring of 2023, with substantial completion scheduled for September 2023. The final wear course will also be in the fall of 2023. This project is feasible, necessary, and cost-effective from an engineering standpoint and should be constructed as proposed herein.

INTRODUCTION 2.1 Authorization On August 19, 2019, the City of Prior Lake City Council authorized the preparation of a feasibility report for the Fish Point Road (CSAH 44 to TH 13) Reconstruction Project in Resolution 19-095. This project has been designated City Project No. TRN 20-000001. The feasibility report focusing on Phase 1 of the project was prepared and accepted by the City Council on September 21, 2020. This feasibility report update pertains to Phase 2 and is provided as a supplement to the original feasibility report. 2.2 Scope This report investigates the feasibility of proposed improvements to street and utilities identified within the City’s Capital Improvement Plan. The streets proposed for the Fish Point Road (CSAH 44 to TH 13) Reconstruction Project were initially considered because of existing pavement conditions and known utility failures. The project includes the following streets . ▪ Fish Point Road SE from 160th Street SE (CSAH 44) to Trunk Highway 13 (TH 13) The project area is shown in Figure 1 of Appendix A. Improvements within this report include roadway reconstruction, public retaining wall replacement, concrete sidewalk replacement, sanitary sewer lining improvements and replacement, watermain replacement, storm sewer improvements, intersection improvements at Fish Point Road and TH 13, and traffic improvements to Twin Oaks Middle School 2.3 Data Available Information and materials used in the preparation of this report include the following: ▪ City of Prior Lake Capital Improvement Plan ▪ City of Prior Lake Assessment Policy ▪ City of Prior Lake Property Index Records ▪ City of Prior Lake Topography Maps ▪ City of Prior Lake Sanitary Sewer Televising Reports ▪ City of Prior Lake Utility Maintenance Logs ▪ City of Prior Lake Pavement and Utility Overall Condition Index Ratings ▪ Geotechnical Report prepared by WSB and completed in March 2020 ▪ Special Benefit Consultation prepared by Patchin Messner Valuation Counselors, dated July 31, 2020 ▪ Field Observations of the Area and Field Topography Surveys ▪ Drone footage of traffic operations during middle school morning drop off and afternoon pick up times along Fish Point Road, just north of CSAH 44, collected on November 9, 2021. 2.4 Background The City of Prior Lake has developed a Capital Improvement Plan to maintain infrastructure within the City. The proposed project area has been identified as a potential street reconstruction project location, where the streets are proposed to be reconstructed and issues with utilities addressed. The City of Prior Lake utilizes a Pavement Management Program to rate the condition of the City’s streets. The pavement rating, known as Overall Condition Index (OCI), is determined based on the amount of pavement deterioration that is visually evident. The street OCI is a number between 0-100, with 100 indicating streets that are in the best condition or are newly paved and 0 being the worst. Streets in need of a mill and overlay generally have an OCI of 45-65 and streets with an OCI between 35-45 Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 3 usually require a full depth reclamation. When the OCI reaches a range of 0-35 or when utility repairs are needed, the street usually requires a full reconstruction. A detailed account of the OCI values for the project area is shown in Table 1. 3. EXISTING CONDITIONS 3.1 Surface The pavement within the proposed improvement area is aging and exhibiting alligator cracking, edge cracking, transverse cracking, longitudinal cracking, stripping (that has since been patched) and some rutting. The bituminous pavement is becoming more brittle due to age and is showing signs of accelerated deterioration. The concrete curb and gutter is in overall poor condition, with locations of cracking and settling. The northern portion of Fish Point Road SE includes medians and turn lanes onto Omega Trail and Trunk Highway 13. The medians are in overall poor condition and show cracking in both the curb and interior concrete. A summary of existing conditions by street is provided in Table 1. Table 1 Fish Point Road (CSAH 44 to TH 13) Reconstruction Project Phase 2 Summary of Existing Conditions Street Name Location ROW (feet) Length (feet) Width* (feet) Existing OCI Fish Point Road SE CSAH 44 to Glory Circle SE 66 2,910 32 - 44 22 Fish Point Road SE Glory Circle SE to TH 13 60 550 32-52** 22 *Back of curb to back of curb street width **Layout includes medians and turn lanes A geotechnical report was completed by WSB in March of 2020. A total of 9 soil borings were taken at various locations along Fish Point Road. The borings indicate bituminous pavement thicknesses from 4 inches to 10 inches. Underlying the pavement was approximately 4.5 inches to 24 inches of aggregate base. The borings showed lean clay and some sand material below the aggregate. The full report can be found in Appendix B. 3.2 Public Utilities The City of Prior Lake owns, operates and maintains storm sewer, sanitary sewer, and watermain within the project area. 3.2.1 Storm Sewer and Drainage Existing and aging storm sewer infrastructure exists within the project area. The storm sewer was installed between 1980 and 1986. Stormwater runoff in the project area is collected into a storm sewer system and is generally discharged to stormwater basins and wetlands located east of Fish Point Road. Stormwater from the northern portion of Fish Point Road and Omega Trail is conveyed by storm sewer across TH 13 and into Lower Prior Lake. Based on field observations, the existing storm sewer is fair-to-poor condition and will need to be upgraded to properly collect and convey stormwater for the proposed roadway and pedestrian improvements. The project is located entirely within the Prior Lake Spring Lake Watershed District (PLSLWD). Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 4 3.2.2 Sanitary Sewer The sanitary sewer system within the project area was constructed in 1972 and consists of 8-inch and 9-inch vitrified clay pipe (VCP). The sanitary sewer for the project area flows north towards the sanitary sewer at Trunk Highway 13, which then flows south along TH 13 via City-owned trunk sanitary sewer facilities to CSAH 21, where the system then connects to the MCES gravity interceptor system that flows west and north to exit the City. The existing sanitary sewer pipe and manholes are in fair condition. 3.2.3 Watermain The watermain system within the project area was installed between 1972 and 1975. The existing watermain on Fish Point Road SE consists of 6-inch and 8-inch ductile iron pipe and 8-inch cast iron pipe. 3.3 Street Lighting Streetlights on utility poles exist on Fish Point Road SE from CSAH 44 to Huron Street SE. 3.4 Sidewalks Between CSAH 44 and Huron Street SE, 5-foot concrete sidewalks with boulevards exists on both the west and east sides of Fish Point Road SE. Between Huron Street SE and Trunk Highway 13, the boulevard between the existing 5-foot concrete sidewalk and the face of curb varies from 0-feet to 5-feet in width. In some locations, the sidewalk extends from the back of curb to the face of existing retaining walls. 3.5 Private Utilities Private utilities that have facilities in or near the project area will be notified during the final desi gn phase of the project and will be requested to coordinate any necessary repairs and replacements as needed at their cost. Private utility companies that may have facilities, both underground and aerial, within the project area include the following: ▪ Center Point Energy (Gas) ▪ CenturyLink (Telephone) ▪ Mediacom (Fiber Optic/Cable) ▪ Minnesota Department of Transportation (Signals) ▪ Scott Rice/Integra Telephone (Telephone) ▪ Xcel Energy (Electric) ▪ Minnesota Valley Electric (Electric) ▪ Zayo (Telecom) Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 5 4. PROPOSED IMPROVEMENTS 4.1 Streets Fish Point Road SE is proposed to be reconstructed with a 24-inch sand section, an 8-inch aggregate section, 6 inches of bituminous pavement, and barrier style concrete curb and gutter. Geotextile fabric will be used to separate the existing subgrade and the new street section. Between CSAH 44 and Huron Street SE the roadway will have 21.5-foot wide traffic lanes to match the existing roadway section that accommodates on-street parking adjacent to the two middle schools. Between Huron Street SE and Trunk Highway 13, the roadway will have 14-foot wide traffic lanes with no on-street parking. The typical sections for these designs are shown in Figures 2 and 3 in Appendix A. The street section designs are based on soil conditions found from the soil borings (see Appendix B), the traffic volumes, previous project experience in the area, and City standards. Within the project, the reconstructed roadway grades will be designed in such a way to minimize impacts to existing neighborhood features such as trees, landscaping, and driveways. Minor modifications to the existing alignment and roadway profile for Fish Point Road will be made to meet current State Aid design requirements. All impacted public retaining walls will be reconstructed based on the recommendations provided in the Geotechnical Report (see Appendix B). Drain tile will be installed with all new street sections within the project area to provide adequate drainage for the roadway subgrade and extend the useful life of the roa dway section. Permanent driver feedback signs (DFB) are proposed to be installed along Fish Point Road as a part of the project. In the past, City Staff has installed temporary DFBs have been installed along Fish Point Road in response to resident concerns regarding vehicle speeds within the corridor. As a part of the improvement project, permanent DFBs will be installed, similar to what was installed along Franklin Trail south of CSAH 44 (160th). City Staff have conducted multiple meetings with representatives from ISD #719 to review traffic congestion issues during peak hours (morning drop-off, afternoon pick-up, and events). Traffic data was collected via aerial camera in November 2021 during the morning drop-off and afternoon pick-up. It was discovered that the left turning movement into Twin Oaks Middle School from northbound Fish Point Road vehicles was a significant contributor to the traffic issues. It does not appear that adding dedicated turn lanes into either school along Fish Point Road will reduce the traffic issues. City Staff plan to coordinate further with school district representatives to evaluate alleviation options during final design . 4.1.1 Right-Of-Way Right-of-way needs, if any, will be identified during the final design process. Temporary construction easements or right-of-entries may be required for grading purposes to provide positive slopes to the curb and to address issues with existing retaining walls. Temporary construction easements may also be necessary along the lot lines in which runoff outlets. 4.1.2 Retaining Walls Public retaining walls within the right-of-way along Fish Point Road SE are proposed to be replaced. Precast Modular Block Walls (PMBWs) will be installed and will match walls installed with other recent public improvement projects. It is anticipated that there will be impacts to existing vegetation associated with wall excavation and construction. Fencing will be installed atop of retaining walls greater than or equal to four-feet in height to provide the necessary fall protection. Fencing is proposed to be black vinyl coated chain link. Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 6 4.2 Public Utilities The City of Prior Lake owns, operates and maintains storm sewer, sanitary sewer, and watermain within the project area. The improvements to these utilities are summarized below. 4.2.1 Storm Sewer and Drainage Reconstruction of the streets provides the opportunity to improve the drainage within the project area through the installation of new or additional storm sewer facilities. Proposed drainage improvements include installation of an entirely new storm sewer collection and conveyance system. Stormwater management improvements will be implemented to achieve the requirements of the Prior Lake Spring Lake Watershed District (PLSLWD) as well as the NPDES and MS4 requirements of the Minnesota Pollution Control Agency (MPCA). Rate control will be provided to ensure proposed discharge rates are less than existing condition or that downstream facilities have the required capacity. Volume control and water quality treatment will be provided to meet the needs of the project. Stormwater credits from previous public improvements projects will be used as appropriate and available to meet the volume control and water quality treatment requirements for this project. A decrease in impervious surface would achieve the requirements of the MS4 permit. If this does not occur, additional stormwater treatment may need to be incorporated. Temporary erosion and sediment control devices will be utilized during construction in accordance with pertinent MPCA NPDES General Construction permit requirements. The costs for the proposed storm sewer improvements are included in Appendix C. 4.2.2 Sanitary Sewer The proposed sanitary sewer improvements consist of replacing all of the VCP sewer pipe within the project area. It is the City of Prior Lake’s practice to replace all sanitary sewer services to the right-of-way with the road reconstruction projects. Parcels that may be subdivided in the future will receive additional services based on the size of the lot. The costs for sanitary replacement are included in Appendix C. 4.2.3 Watermain New 8-inch PVC watermain is proposed along the project corridor. Full watermain replacement including replacement of all water services and curb boxes within the project area is proposed as part of the improvements. Temporary water services will need to be provided to maintain service to the affected properties while the main is replaced. Hydrants, valves, and services will also be replaced in these areas as needed. All parcels will receive a new service to the right-of-way. Parcels that may be subdivided in the future will receive additional services based on the size of the lot. The costs for watermain replacement are included in Appendix C. 4.3 Street Lighting The streetlights that exist along Fish Point Road SE are limited to that portion of the road between CSAH 44 and Huron Street SE and the intersections at Hidden Oaks Circles SE and Trunk Highway 13. The replacement of existing streetlights and the addition of new streetlights, especially at intersections, has been standard practice with past improvements projects within the City. The proposed streetlights for the project will be rectilinear style with LED style bulbs. Streetlights will be owned and maintained by the electric service providers for this area (Xcel Energy and Minnesota Valley Electric ). Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 7 4.4 Sidewalks Replacement of the 5-foot wide concrete sidewalk is proposed along Fish Point Road SE. From CSAH 44 to Huron Street SE, a 5.5-foot boulevard is proposed between the face of the curb and the edge of the sidewalk. Between Huron Street SE and Trunk Highway 13, the boulevard width will vary between being 0.5-feet wide and 5-feet wide, such that the sidewalk will be reinstalled in a similar location to preconstruction conditions where adjacent retaining walls and right-of-way locations limit the creation of boulevard spaces between the roadway and the sidewalk. Pedestrian curb ramps meeting current ADA standards will be constructed at sidewalk connections with the residential streets. New concrete sidewalk along the west side of Fish Point Road from Omega Trail SE to TH 13 is proposed based on feedback from residents. This sidewalk would create a connection to the sidewalk on the east side of Fish Point Road that utilizes a signalized crosswalk . Installation of such a sidewalk will result in the need for additional right-of-way, and thus is dependent on cooperation from the property owner. Private utility impacts and retaining wall needs associated with the construction 4.5 Intersection Improvements The medians and turn lanes at the Fish Point Road SE and Timber Trail SE/Omega Trail SE and at Fish Point Road SE and Trunk Highway 13 are proposed to be removed and/or reconfigured with this project. The median south of Omega Trail SE is proposed to be eliminated and replaced with pavement markings, while the northern median will be relocated to allow for the construction of a dedicated southbound left turn lane onto Timber Trail SE, as well as dedicated north and southbound turn lanes onto TH 13 from northbound Fish Point Road. See Figure 4.5.1 below. Figure 4.5.1 Feasibility Report Fish Point Road (CSAH 44 to TH 13) Reconstruction Project City Project No. 2023-01 City of Prior Lake WSB Project No. R-13977-000 8 4.6 Permits/Approvals The anticipated permits and approvals, and the respective regulatory agencies, are listed below: ▪ Minnesota Pollution Control Agency (NPDES) ............................... Erosion/Storm Water Permit ▪ Minnesota Department of Transportation (TH 13) ...................................... Right-of-Way Permit ▪ Scott County (CSAH 44) ............................................................................. Right-of-Way Permit ▪ Minnesota Department of Health ............................................... Extension of Watermain Permit ▪ Prior Lake Spring Lake Watershed District……………..Stormwater and Erosion Control Permit In addition to a Right-of-Way Permit, the City will work with MnDOT to obtain the necessary approvals associated with the intersection improvements at Fish Point Road and TH 13, including the relocation of the existing signal arm to facilitate the construction of north and southbound turn lanes onto TH 13 from Fish Point Road. Costs for reconfiguration of the signal system are included in Appendix C. 4.7 Construction Access/Staging A detour for Fish Point Road SE will be necessary to keep non-local traffic from entering the project area and to maintain access to the middle school sites during construction. Fish Point Road will be closed to through traffic, and open to “Local Traffic Only,” during construction. The neighborhood will experience times during utility and retaining wall construction and other work tasks where ingress and egress is restricted during the day. Alternative routes through the neighborhood may need to be utilized to access driveways. It is anticipated that construction activities throughout the project area will be phased during the 2023 construction season. Additional details regarding phasing and detour plans will be developed with the final design of the project. Phasing of the project will allow for portions of Fish Point Road to remain open while other segments are closed to thru traffic. Access to driveways will be restricted during and after concrete curb and concrete driveway patches are poured. City Staff has been coordinating with ISD #719 on bus access and construction activities during the 2023- 2024 school years, though it is anticipated that the segment of Fish Point Road adjacent to the middle schools will be completed prior to Labor Day 2023. City Staff will continue to work with the school district to coordinate access to both middle schools during the summer months to ensure planned Community Education offerings at the middle school can continue, in addition to planned athletic club use of the middle school sites and Lakefront Music Fest Parking. School district representatives have suggested that many, if not all, events can be moved to another location for the su mmer. 4.8 Public Involvement Public informational meetings for the proposed project have been conducted by the City on multiple occasions throughout the multi-year project. Information has been presented to attendees regarding the proposed improvements, funding sources, schedule, and impacts associated with the project. An open house meeting will be conducted in January 2022, after the feasibility report is accepted by City Council, but prior to final design.

INTRODUCTION Project Location The site is located along Fish Point Road between State Hwy 13 and 160th Street SE, as well as Timber Trail SE, Glory Circle, Hidden Oaks Circle, Timberview Street, M illers Circle, and Omega Trail, all within Prior Lake, Minnesota. The approximate soil boring locations can be found on the Soil Boring Exhibit in Appendix A. Project Description It is our understanding that this project consists of reconstruction of Fish Point Road between State Hwy 13 and 160th Street SE, as well as reconstruction of Timber Trail SE, Glory Circle, Hidden Oaks Circle, Timberview Street, Millers Circle, and Omega Trail. Along with pavement reconstruction and installation of concrete curb and gutter, we understand the underground utilities (watermain, sanitary) will be reconstructed across much of the project. Retaining walls along the roadway wi ll also be reconstructed. We understand that the sanitary sewer within the southern half of the project is at depths of about 25 feet below existing pavement grade. We understand the horizontal and vertical alignment of the roadways will remain relativ ely unchanged from existing conditions. WSB has developed foundation recommendations for this project in consideration of the proposed layout, loadings, and structural configurations as understood at this time. When the designer develops additional information about final design structural loadings, building configuration, or other significant factors, the recommendations presented herein may no longer apply. WSB should be made aware of the revised or additional information in order to evaluate the recommendations for continued applicability. Purpose and Project Scope of Services Monica Heil with WSB requested these services which were authorized by Nick Monserud with the City of Prior Lake. In order to assist the design team in preparing plans and specifications, we have developed recommendations for retaining wall foundations, underground utilities and pavements. As such, we have completed a subsurface exploration program and prepared a geotechnical report for the referenced site. This stated purpose was a significant factor in determining the scope and level of service provided. Should the purpose of the report change the report immediately ceases to be valid and u se of it without WSB’s prior review and written authorization should be at the user’s sole risk. Our authorized scope of work has been limited to: 1. Clearing underground utilities utilizing Gopher State One Call. 2. Mobilization / demobilization of a truck mounted drill rig. 3. Drilling 9 standard penetration borings to 20 foot depths. 4. Drilling 9 standard penetration borings to 30 foot depths. 5. Sealing the borings per Minnesota Department of Health procedures. 6. Perform soil classification and analysis. 7. Review of available project information and geologic data. 8. Providing this geotechnical report containing: a. Summary of our findings. b. Discussion of subsurface soil and groundwater conditions and how they may affect the proposed underground utilities and pavements. c. Estimated allowable bearing capacity of the soils. d. Estimated excavation depths to suitable soils. e. Estimated R-value of the soils. f. Recommended pavement section. g. A discussion of soils for use as structural fill and site fill. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 2 2. PROCEDURES 2.1 Boring Layout and Soil Sampling Procedures WSB completed 18 standard penetration soil borings along the proposed roadway improvement areas. WSB recommended the boring depths and selected the desired locations. Our field crew staked the borings by estimating from existing site features from the supplied site plan. The approximate boring locations are shown on the Soil Boring Exhibit in Appendix A which is an aerial photo. The ground surface elevations at the borings were estimated by using LIDAR data with 2 foot contours. These maps should be accurate to within +/- one foot (1’) provided ground surface modifications at this site have not been completed since LIDAR data was obtained. The borings were completed within the roadways and were not completed at the base of any existing retaining walls. We completed the borings between September 9 and September 27, 2019 with a truck-mounted CME-55 drill rig operated by a two-person crew. The drill crew advanced the borings using continuous hollow stem augers. The drilling information is provided on the boring logs. Generally, the drill crew sampled the soil in advance of the auger tip at two and one-half (2 ½) foot intervals to a depth of 15 feet and then at five (5) foot intervals thereafter to the termination depth of the boring. The soil samples were obtained using a split-barrel sampler which was driven into the ground during standard penetration tests in accordance with ASTM D 1586, Standard Method of Penetration Test and Split-Barrel Sampling of Soils. The materials encountered were described on field logs and representative samples were containerized, and transported t o our laboratory for further observation and testing. The samples were visually observed to estimate the distribution of grain sizes, plasticity, consistency, moisture condition, color, presence of lenses and seams, and apparent geologic origin. We classified the soils according to type using the Unified Soil Classification System (USCS). A chart describing the USCS is included in Appendix A. 2.2 Groundwater Measurements and Borehole Abandonment The drill crew observed the borings for free groundwater while drilling and after completion of the borings. These observations and measurements are noted on the boring logs. The crew then backfilled the borings to comply with Minnesota Department of Health regulations. 2.3 Boring Log Procedures and Qualifications The subsurface conditions encountered by the borings are illustrated on the Logs of Test Borings in Appendix A. Similar soils were grouped into the strata shown on the boring logs, and the appropriate estimated USCS classification symbols were also added. The depths and thickness of the subsurface strata indicated on the boring logs were estimated from the drilling results. The transition between materials (horizontal and vertical) is approximate and is usually far more gradual than shown. Information on actual subsurface conditions exists only at the specific locations indicated and is relevant only to the time exploration was performed. Subsurface conditions and groundwater levels at other locations may differ from conditions found at the indicated locations. The nature and extent of these conditions would not become evident until exposed by construction excavation. These stratification lines were used for our analytical purposes and, due to the aforementioned limitations, should not be used as a basis of design or construction cost estimates. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 3 3. EXPLORATION RESULTS 3.1 Site and Geology The borings were completed through the existing bituminous surfaced roadways. Approximate boring elevations ranged from 946 to 996 feet, and indicate an undulating terrain. Geologic origins can be difficult to determine solely from boring samples. We referenced online geologic data of the area and used our experience to help determine geologic origin of the soils, however only a detailed geologic exploration would accurately determine the geologic history of the site. The Scott County Geologic Atlas indicates the surficial geology of the area is mostly bedrock consisting of glacial till deposits consisting of a mixture of clay, silt, and sands. Gravels and cobbles are present in areas and layers of lean clay or silt may be encountered. 3.2 Subsurface Soil and Groundwater Conditions The boring profile generally consisted of the pavement section and fill materials overlying glacial till and outwash deposits. Pavement section The pavement section generally consisted of bituminous asphalt overlying an aggregate base material. The bituminous asphalt generally ranged from about 4 to 10 inches in thickness and averaged just over 6 inches. The aggregate base consisted of crushed limestone and natural granular soils consisting of sands, sands with silt, and silty sands with various amounts of gravel. The aggregate base generally ranged from about 4 ½ to 24 inches in thickness and averaged just over 8 inches. Fill The borings encountered fill materials at PB-01, PB-02, PB-03, PB-06, PB-12, PB-13, and PB-18. The fills generally consisted of lean clays with sand, silty clays, organic clays, and clayey sands. The fills were brown to dark brown to gray to black in color and generally moist to wet. Glacial deposits The predominate soils encountered in the borings were glacial deposits. These glacial till and outwash deposits generally consisted of lean clays with sand, sandy lean clays, silty clays, clayey silts, clayey sands, silty sands, and sands with various amounts of gravel. These soils were brown to dark brown to reddish brown to gray in color and were generally moist to wet. Table 1 below presents the existing roadway pavement section and subgrade profiles.

Those values provide an indication of soil strength characteristics and are located on the boring log sheets. Also, visual-manual classification techniques and apparent moisture contents were also utilized to make an engineering judgment of the consistency of the materials. Table 2 presents a summary of the penetration resistances in the soils for the borings complet ed and remarks regarding the material strengths of the soils. Table 2: Penetration Resistances Soil Type Classification Penetration Resistances Remarks Fill Varies 4 to 24 BPF Variable compaction Glacial Deposits (cohesive) CL, SC 4 to 95 BPF Average 16 BPF Very soft to very hard Generally hard Glacial Deposits (cohesionless) SP, SP-SM, SM, ML 2 to 68 BPF Average 17 BPF Very loose to very dense Generally medium dense The preceding is a generalized description of soil conditions at this site. Variations from the generalized profile exist and should be assessed from the boring logs, the normal geologic character of the deposits, and the soils uncovered during site excavation. 3.4 Groundwater Conditions WSB took groundwater level readings in the exploratory borings, reviewed the data obtained, and discussed its interpretation of the data in the text of the report. Note that groundwater levels may fluctuate due to seasonal variations (e.g. precipitation, snowmelt and rainfall) and/or other factors not evident at the time of measurement. The bore holes were only left open a short period of time, and groundwater levels may not have stabilized. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 5 Table 3 below is a summary of the estimated water levels at our borings.

Elevations rounded to the highest ½ foot. Groundwater was encountered in Borings PB-02 and PB-06. Many of our borings encountered sands at depth that were considered moist as opposed to wet or waterbearing, indicating a static groundwater level is likely below the depths of those borings. We also noted gray colored soils in many of the other borings. Gray colored soils can be an indication of long term saturation conditions and could show potential groundwater elevations. Lower Prior Lake is located approximately 500 feet north of the proj ect. Based on data from the Minnesota Department of Natural Resources, Lower Prior Lake has an ordinary high water level of 903.9 feet. Based on this, it is our opinion that the groundwater encountered during drilling is likely a perched groundwater table, however perched groundwater could have substantial volumes and may not be easy to dewater. The perched groundwater could present an issue to excavations and placement of foundations and for utility installation. It is our opinion that the contractor should be prepared for dewatering. It should be noted that groundwater readings are difficult to obtain in cohesive soils such as the lean clays indicated in the boring logs. These soils have a low permeability and take a long period of time to obtain groundwater readings in. If more accurate subsurface water levels are needed, we recommend piezometers be installed to determine the groundwater level over several months. Monitoring of the Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 6 groundwater table elevation could occur up to the time of construction. This work was outside our scope of services. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 7 4. ENGINEERING ANALYSIS AND RECOMMENDATIONS 4.1 Discussion Fills No information was provided to us regarding density tests or excavation observations for the existing fills encountered at the boring locations. The best option is complete removal of fills materials below all pavements and utilities. However, these fills were likely placed during initial roadway or utility construction and have been under traffic loading for many years. In our opinion, the risk of construction of the pavement area or a utility upon these soils is generally low. The City may option for a partial removal of the organic and wet fill materials. The borings were completed in the roadway areas, however we used the boring data for the nearby retaining walls. Fills should be removed entirely below the retaining wall foundation. These soils may be suitable for reuse if they are free of organics and can be moisture conditioned to meet compaction requirements. Glacial Deposits Based on the results of our borings, the glacially deposited soils generally appear capable of supporting the retaining walls, pavement section, and utilities. However, some of the clayey or silty soils are locally wet and would require a partial excavation and replacement. General It is our opinion that perched groundwater could be encountered by excavations at this site and could affect construction of foundations and utilities. The contractor should be prepared for dewatering. Generally, the soils in the upper 4 feet of the subgrade influence pavement performance the most. The soils within the pavement subgrade consist of clays and silts, which are frost susceptible soils. Consideration should be given to partially subcutting these soils an d replacing with a non-frost susceptible granular fill to reduce the potential frost heave below the pavement section. Silt soils are also not recommended for direct support of pavements for the aforementioned frost reasons but also because they are sensitive to moisture changes, easily disturbed by construction traffic, and difficult to compact. Where silt soils are present at the top of grading grade we expect a partial subcut and replacement with an engineered fill is recommended. 4.2 Retaining Wall Area Preparation We recommend removal of the fills and organics from below the retaining walls. Additionally, we recommend a minimum of 1 foot of granular fill be placed directly below the retaining wall foundations for support. If wet silt/clay soils that are loose/soft or become loose/soft are present under the 1 foot subcut they should be subcut a minimum of another 1 foot. Loosened sands at bottom of footing elevations should be surface compacted with a large vibratory roller having a drum diameter of at least five feet (5’) and a static dead weight of at least ten (10) tons prior to placement of engineered fill and backfill or concrete. The sub-excavations should be oversized by at least one foot (1’) beyond the edge of footings for each foot of depth below the bottom of footing elevations (1-horizontal to 1-vertical lateral oversizing). Because the depth and lateral extent of the sub-excavations will vary away from our borings, we recommend a qualified engineering technician working under the direction of a registered professional geotechnical engineer observe and test the excavation bases during construction. Based on the borings, it appears that the on-site non-organic soil can generally be reused as structural backfill provided it is moisture conditioned and can be compacted to project specifications. However, silt soils will be difficult to place and compact especially when wet and are not recommended as fill below the retaining wall foundation or as backfill materials. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 8 The site should be graded to prevent water from ponding on silty or clayey soils and potentially softening them. 4.3 Foundation Recommendations We recommend that the retaining wall foundations in this development be supported on conventional spread footings bearing on a minimum of 1 foot of granular fill placed over naturally occurring glacial deposits. Based on the borings, it is our opinion the footings throughout may be designed for a net allowable soil bearing pressure not to exceed 2,000 pounds per square foot (psf). Frost protection should follow Minnesota Administrative Rules 1305.1809. We recommend unheated footings be placed at least five feet (5’) below adjacent exterior grade. The factor of safety against shear or bearing capacity failure for this footing design would be three (3) or greater. If the site is prepared as recommended, we estimate that total and differential se ttlements corresponding to our assumed structural loads would be less than one inch (1”) and one -half inch (1/2”), respectively, provided the bearing soils are not frozen or disturbed at the time of construction. 4.4 Excavations Near Existing Structures The construction planned at this site will require some excavations near existing structures. We recommend that the owner be involved with the contractor and engineer in determining what level of care will be needed to ensure that there is no undermining of any existing foundation or slab and that no sensitive equipment could be damaged by nearby construction. Monitoring of the excavation and existing building can be completed with visual observations, vibration monitoring, crack monitoring, pr e and post construction video surveys, and survey elevation points on the existing structure. At no time should the excavations extend below existing footings or within a 1:1 oversize below the footings, unless that foundation is properly braced and supported. 4.5 Retaining Walls To help prevent water from accumulating behind retaining walls in clayey or silty soils, we recommend drain tiles be placed at the base of the granular subbase. To promote water migration to the drain tile, we recommend either a drainage composite be placed against the back side of the wall or at least two feet (2’) (horizontally) of clean coarse sand be placed along the back of the wall. We recommend the upper foot of backfill consist of clayey soils to act as a “cap” and reduce water infiltration into the backfill soils. The drain tile should be connected to the storm sewer system or “daylighted” to suitable disposal areas. To assist in below-grade/retaining wall design Table 4 presents estimated soil parameters for common backfill soils. The coefficients presented below assume a level backfill at the top of wall. If the backfill is sloped, these values may change significantly. Silt (ML) is not recommended as backfill for walls.

Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 9 4.6 Backfill and Fill Selection and Compaction The on-site non-organic soils may be reused as backfill and fill provided they are moisture conditioned and can be compacted to their specified densities. Organic soils removed during the excavation process should be limited to use as fills in landscaping areas. Wet soils that are excavated would need to be dried before reuse as an engineered fill. Silt soils are not recommended for reuse below foundations, utilities, or the pavement section and should be used only in landscaping areas. We recommend use of a minimum of 2 feet of clean coarse sand with less than 50 percent passing the #40 sieve and less than 5 percent passing the #200 sieve when backfilling the bottom of a wet excavation. Backfills with cobbles larger than six inches (6”) should not be placed within 3 feet of grading grade or the retaining wall foundations or in contact with utilities. We recommend that clayey soils be moisture conditioned to within +/-2 percent of the optimum moisture content as determined from their standard Proctor tests (ASTM D-698). Fill should be spread in lifts of 8 to 12 inches, depending on the size and type of compaction equipment used. Table 5 provides the recommended compaction levels. Table 5: Recommended Level of Compaction for Backfill and Fill Area Percent of Standard Proctor Maximum Dry Density Retaining Wall Foundation 95 Pavement: Within 3 feet of bottom of aggregate base Within 3 foot radius of vertical utility structure 100 Pavement: Greater than 3 feet below aggregate base 95 Utility Trench 95 Landscaping (non-structural) 90 4.7 Pavement Subgrade Preparation and Stability We recommend excavation of any organic fills within 3 feet of the bottom of the aggregate base or within 3 feet of the utility invert. The soils at the bottom of the excavation should generally be prepared in accordance with MnDOT Specification 2112, Subgrade Preparation. If the subgrade preparation operations encounter unstable soils, we recommend removing these unsuitable materials and replacing them with Select Grading Material (MnDOT 2105.1.A.6). If the on-site soils cannot be moisture conditioned and compacted as recommended, additional measures, such as placement of additional sand subbase or a section of coarse breaker run aggregate, can be completed to provide a firm base for subsequent fill placement. Before placement of the sand subbase, the final subgrade should have proper stability within three vertical feet of grading grade (grade which contacts the bottom of the aggregate base). This will generally be achieved in fill areas with proper compaction of embankment materials and in cut areas through proper subgrade preparation. The stability of the pavement subgrade should be evaluated prior to placement of the sand subbase using the test roll procedure (MnDOT 2111), except a fully l oaded tandem axle dump truck or a full water truck should be utilized for the proof roll. If unstable soils are found under the test roll, these soils should be improved by means of scarification, moisture conditioning, and re - compaction, or by subcutting and replacement. We recommend placement of a geotextile fabric meeting the requirements of MnDOT Specification 3733, Type V beneath the sand subbase and above the on-site silt soils to limit mixing of the granular materials with the underlying fine-grained subgrade. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 10 4.8 Pavement Area Once the site has been prepared as recommended, we anticipate the prepared subgrade soils will consist mostly of lean clays, sandy clays, clays with sand, and sands. Based on the MnDOT Flexible Pavement Guide from 2017, the R-values of the subgrade soils would range between 10 and 70. We used a design R-value of 10 for the roadways based on the predominance of the clay soils. North Fish Point Road (North of Huron Road) Information provided to us indicates that traffic along North Fish Point Road has an Annual Average Daily Traffic (AADT) traffic volume of 1554. We estimated that traffic volumes would increase at an average rate of 2.5%. Based on the traffic data provided to us, the traffic loading consists of 62% passenger vehicles, 32% vans and pickups, 2% bus and truck traffic, and 4% tractor -trailers. Our design is based on a standard twenty (20) year design life of the pavement section. Based on the estimated traffic ADT we used the Minnesota State Aid Traffic Design forecast program to calculate the roadway traffic to be equivalent to approximately 301,000 Equivalent Single Axle Loads (ESAL’s) for roadway design. This is based on an Urban vehicle classification on a 2-lane road. Our Minnesota State Aid Traffic Design forecasting was based on a 10-ton road design. Based on MnDOT’s FlexPave excel design utilizing granular equivalent charts, we recommend the pavement section indicated below in Table 6.

Based on the roadways being cul-de- sacs, we assumed the ESAL’s would be less than 50,000. Our Minnesota State Aid Traffic Design forecasting was based on a 10-ton road design. Based on MnDOT’s FlexPave excel design utilizing granular equivalent charts, we recommend the pavement section indicated below in Table 8.

Aggregate base placement for pavement support should meet the gradation and quality requirements for Class 5, 5Q, or 6 per MnDOT specification 3138. Aggregate base material should be compacted to 100 percent of its standard Proctor maximum dry density. Within several years after initial paving, some thermal shrinkage cracks will develop. We recommend routine maintenance be performed to improve pavement performance and increase pavement life. Pavement should be sealed with a liquid bitumen sealer to retard water intrusion into the base course and subgrade. Localized patch failures may also develop where trucks or buses turn on the pavement. When these occur, they should be cut out and patch repaired. The pavement sections above provide options to meet the ESAL requirements. Other pavement design options would be acceptable as well as long as they meet the minimum requirements for bituminous thickness, aggregate base thickness, and can meet the ESAL requirements. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 12 4.9 Optional Frost Free Pavement Design Optionally, the use of a non-frost susceptible sand cushion will help reduce the effects of frost heave. In our opinion, placement of 12 inches of select granular fill below the Class 5 Aggregate Base should generally provide for a non-frost susceptible subgrade. It should be noted that any sand cushion placed below the pavement section will provide positive benefits for reduced potential frost heave. The owner and/or design team should evaluate the costs and benefit of this option to determine if it should be incorporated into the pavement design. Drainage of the sand cushion is recommended. Drainage of the sand cushion may be accomplished by daylighting to adjacent ditches or the use of drain tile. Drain tile wrapped in a sock should be placed at the base of the sand cushion and tied into catch basins. We recommend the sand cushion contain a select granular sand with less than 12% passing the #200 sieve. Alternately, a 3 inch minus rock fill could be placed instead of a select granular sand and drain tile. For transitioning the thickness of the sand subbase along the profile of the roadway, we recommend the thickness have a longitudinal taper of no steeper than 10H:1V. A taper of 4H:1V can be used perpendicular to the centerline for cross street/driveway connections. The placement of the sand subbase should extend slightly beyond the outer edge of the curbs to maintain subgrade uniformity for frost movement. 4.10 Utilities Invert elevations for the sanitary sewer are anticipated to be within 15 to 25 feet below existing grades and watermain would be approximately 8 to 10 feet below grade. Based on the borings, the subgrade soils for the utilities will consist chiefly of lean clays with sand, sandy clay, silty sand, and sand. We recommend removal of any organic soils of existing fills from within 3 feet below the utility invert. Any wet silts/clays should be subcut a minimum of 2 feet and replaced with an engineered fill. MnDOT Specification 3149.2F Granular Bedding should be placed to at least the crown of the pipe. Trench backfill above this point may consist of the non-organic excavated soils once moisture conditioned as recommended. Underground utilities are expected to be installed by backhoes completing the excavations and placing fills. Soil compactors should be used to compact the fill in even lifts to the specified densities. 4.11 Dewatering Groundwater and wet or saturated soils were encountered in the borings. Perched groundwater could enter the excavations. Dewatering can likely be accomplished with sumps and pumps placed at low points in the utility trenches. Where granular soils are present, dewatering greater than 2 feet could require sand point wells. 4.12 Construction Considerations Good surface drainage should be maintained throughout the work so that the site is not vulnerable to ponding during or after a rainfall. If water enters the excavations, it should be promptly removed prior to further construction activities. Under no circumstances should fill or concrete be placed into standing water. Soil corrections at this site for foundations and pavement subgrades may not be continuous. We recommend tapering the fills back to native soils at a ten to one (10:1) slope. It is important to review the fill limits and total depth of fill when placing str uctures upon compacted materials and when filling the excavation. The location of the footings should allow for at least a one to one (1:1) slope from the bottom of the footing to the outside limits of the engineered fill. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 13 It is important to check this at the time of construction that during filling, unsuitable soils do not encroach within the one to one (1:1) slope limits and extending downward and outward from future footings. 4.13 Construction Safety All excavations should comply with the requirements of OSHA 29 CFR, Part 1926, Subpart P “Excavations and Trenches”. This document states that excavation safety is the responsibility of the contractor. Reference to this OSHA requirement should be included in the job specifications. The responsibility to provide safe working conditions on this site, for earthwork, building construction, or any associated operations is solely that of the contractor. This responsibility is not borne in any manner by WSB. 4.14 Cold Weather Construction It is our understanding that construction is unlikely to occur during the winter months. However, if the construction does continue into the winter months we recommend the following guidelines. Roadbed embankments should not be constructed during periods when t he embankment material freezes while being placed and compacted, nor should embankment material be placed on soil that is frozen to a depth greater than 4 inches. When the soils are frozen to a depth exceeding 4 inches, at a time when weather conditions are such that embankment construction could be continued without the material freezing as it is being placed and compacted, the contractor may be permitted to excavate the frozen soil and proceed with the embankment construction for so long as the weather w ill permit. The frozen soils should be pulverized or replaced with other suitable soils to construct the embankments as specified. Only unfrozen fill should be used. Placement of fill and/or foundation concrete should not be permitted on frozen soil, and the bearing soils under footings or under the floor slab should not be allowed to freeze after concrete is placed, because excessive post-construction settlement could occur as the frozen soils thaw. 4.15 Field Observation and Testing The soil conditions illustrated on the Logs of Test Borings in Appendix A are indicative of the conditions only at the boring locations. For this reason, we recommend that excavations at this site be observed by a soil engineer or technician prior to fill or backfill placement or construction of foundation elements to determine if the soils are capable of supporting the fill backfill and/or foundation loads. These observations are recommended to judge if the unsuitable materials have been removed from within the planned construction area and an appropriate degree of lateral oversize has been provided. WSB also recommends a representative number of field density tests be taken in engineered fill and backfill placed to aid in judging its suitability. Fill placement and compaction should be monitored and tested to determine that the resulting fill and backfill conforms to specified density, strength or compressibility requirements. We recommend at least one compaction test for every 50 linear feet along the retaining walls, and one compaction test for every 150 feet of utility trench at a vertical interval of two (2) feet. Prior to use, proposed fill and backfill material should be submitted to the WSB laboratory for testing to verify compliance with recommendations and project specifications. Dynamic Cone Penetrometer (DCP) tests can be completed in the aggregate base in lieu of density testing. We recommend following MnDOT Specification 2211.3.D.2.c. WSB would be pleased to provide the advised field observation, monitoring and testing services during construction. 4.16 Plan Review and Remarks The observations, recommendations and conclusions described in this report are based primarily on information provided to WSB, obtained from our subsurface exploration, our experience, several assumptions and the scopes of service developed for this project and are for the sole use of our client. Geotechnical Report 2021 Street Improvements Prior Lake, Minnesota WSB Project No. 013977-000 Page 14 We recommend that WSB be retained to perform a review of final design drawing and specifications to evaluate that the geotechnical engineering report has not been misinterpreted. Should there be changes in the design or location of the structures related to this project or if there are uncertainties in the report we should be notified. We would be pleased to review project changes and modify the recommendations in this report or provide clarification in writing. The entire report should be kept together; for example, boring logs should not be removed and placed in the specifications separately. The boring logs and related information included in this report are indicators of the subsurface conditions only at the specific locations indicated on the Soil Boring Exhibit and times noted on the Logs of Test Boring sheets in Appendix A. The subsurface conditions, including groundwater levels, at other locations on the site may differ significantly from conditions that existed at the time of sampling and at the boring locations. The test borings were completed by WSB solely to obtain indications of subsurface conditions as part of a geotechnical exploration program. No services were performed to evaluate subsurface environmental conditions. WSB has not performed observations, investigations, explorations, studies or testing that are not specifically listed in the scope of service. WSB should not be liable for failing to discover any condition whose discovery required the performance of services not authorized by the Agreement .

There are City- owned timber retaining walls (built around 1984) that are beginning to degrade at the north property line, and private landscape block retaining walls. They are requesting that the walls are replaced at the City’s cost. City and WSB staff indicated that attempts will be made to locate property corners and verify that the timber wall is within the road right- of-way. - There is an existing storm sewer grate/inlet at the base of the landscape block wall that appears to connect to the storm sewer in the street via an 18” RCP pipe. The residents indicated that when that was first installed it would backup in major storms and had flooded their basement. The City completed some adjustments many years ago, and it hasn’t been as much of an issue since. WSB will incorporate this storm sewer inlet into the site analysis. - It was also discussed that all of the shrubs along the top of the wall were in very close proximity to the road and would likely need to be removed. The residents stated they were fine with that, but also stated that their goal is to “screen” the sight an d noise of traffic along the street and along TH 13. - It was noted that their services are off of Fish Point Road and on preliminary review, their replacement didn’t seem to require any tree removals in their front yard. - The landscaping and trees at the northwest corner of their property will likely need to be removed and the residents stated they were fine with that. 5910 Glory Circle SE (Michael Autenrieth) & 5901 Glory Circle SE (Kory Mosher) - This was a joint meeting with both residents. One main question/concern was if the watermain and sanitary sewer between their two properties is going to be replaced. Both of their services come from the side yard mains within the easement. The water service for 5910 was located, and an attempt was made to locate 5901. - The resident at 5910 Glory Circle SE indicated that during major rain events, about every 5-6 years, there is a ravine behind 5900 that essentially floods and runs between the two houses and into the storm sewer inlet in the cul-de-sac. He stated that the house at 5900 has flooded many times. City and WSB staff investigated along Timber Trail SE and determined that it is likely all the drainage is coming from the area outside of City ROW and from rear yards and roof tops. This, however, will be evaluated with the stormwater analysis. - The resident at 5901 asked how much of their driveway would be impacted and if their pine tree in the boulevard would be impacted and replaced if impacted. Nick M. stated that the tree will likely be affected, and if it is in the ROW it won’t be replaced, but if it is K:\013977-000\Admin\Meeting\8 5 20 Phase 1 Property Owner Meetings\Property Owner Meeting Summary.docx on private property, it will. He also gave the resident an approximate location of driveway removals. 5910 Miller’s Circle SE (Jody Stroh) - The resident’s main question was regarding the large timber retaining walls that abut the street on the west side of her property and continue up her driveway toward her garage. It was determined that her sewer and water service are underneath the portion of the wall adjacent to the driveway and that they would be impacted. It was discussed that final wall replacement details will come with design, but that it is likely the project will only replace the portion of the wall impacted by utility work and that the property owner would be responsible for replacing any other portion of the wall if they do desired. She asked how that coordination would work and Andy B. stated that the logistics will be more thought out as we get into design and it will be communicated back to the property owners. - It was also noted to the resident that the two large trees in her front yard will likely be impacted by the sewer and water service replacement. Andy B. explained that there may be a chance that they could be saved during the replacement but may die in a few years if the root system is impacted. He discussed there may be a benefit to having the cost of the tree removal be covered by the project as opposed to the resident later on. - The resident indicated that she would like to keep the retaining wall on the east side of her property if at all possible. 5833 Timber Trail SE (Robert Dudzik) - The resident’s main concern was what impacts are proposed to the timber retaining walls. He indicated that he built the walls and would like to keep them in place if possible. The City and WSB investigated as to the location of the sewer and water service and noted that the water service was in the driveway, about 8’ from the edge of the retaining wall. The resident recalled that the sewer service comes out of the hose on the west side of the property but then angles towards the driveway and runs adjacent to the water service. City and WSB staff will review sewer televising tapes for the area to better determine where this service comes into the main. - The resident also asked what sort of access there will be to his property, as he is currently experiencing mobility challenges. The response was that WSB and City staff will work to communicate access needs to the contractor and require that special accommodations be made to provide access. In general, access to the driveway will be maintained at the beginning and end of each working day for vehicles, except when the concrete curb is curing for 5 days in front of the driveway. 15654 Omega Trail SE (Christopher Wickstrum) - This resident was joined by his neighbor to the east at 15659 Omega Trail SE. One question/concern raised by these residents was how the project will address the improper drainage of the cul-de-sac. They noted that water pools at the end of their driveways and does not make its way down the street to the north. They were curious if improvements to the street could help reduce the slope of their driveways as well. Staff relayed that this drainage issue would be addressed with the storm sewer and street design, and that there is a chance that the cul-de-sac can be raised slightly to help with the steep driveways. - They asked if the private utility pedestals could be moved and/or consolidated with the project. Staff relayed that the City and WSB coordinate with private utilities but that there are typically no restrictions or requirements to move existing pedestals. The City and WSB will notify the private utilities of the residents ’ request. K:\013977-000\Admin\Meeting\8 5 20 Phase 1 Property Owner Meetings\Property Owner Meeting Summary.docx - It was also request that Public Works staff review how snow is stored in the cul-de-sac, as currently they pile it up on the property at 15654 and cover up an electrical transformer and cable pedestals. - The resident at 15654 indicated that they would like to widen their driveway to 24’ wide. Nick M. said that this resident should coordinate with the field staff when curb and gutter is being installed. - Lastly, they requested that the design consider an addition of a cross walk at Fish Point Road and Omega Trail. They have children that are too close to the school to bus, but don’t feel safe crossing the road to get on the sidewalk along the east side of Fish Point Road. The City said that internal discussions are being had about this issue and the design will consider a crossing, or extension of the sidewalk on the west side, so that the crossing at TH 13 can be added and utilized. 15489 Omega Trail SE (Dianna & Greg Running) - The resident’s primary concern was a drainage issue in their yard were water is being held since the street is higher than their yard. This low area somewhat drains to an existing plastic pipe that goes under their driveway and connects to the storm sewer catch basin in the roadway. They were told that storm sewer will be extended into their yard and a catch basin will be installed to collect the drainage and bring it into a new RCP pipe underneath the curb line in their street. The project will also rem ove the existing plastic pipe and replace their heaved concrete apron. - They indicated that they would like to keep the large oak tree to the left of their driveway but were told it is likely that with the storm sewer replacement this tree would have to b e removed. They indicated that would be alright, if it’s necessary. They also stated all the shrubs along the street are ok to be removed. 15480 Omega Trail SE (Kelly Flanagan) - The resident was not home at the meeting time of 3:30 pm. She was contact ed by Kirsten Gray, but wasn’t going to be home until 5:00 pm when the meetings were wrapping up. She was told that the City and WSB would reschedule a meeting. 5925 Hidden Oaks Cir (Judy Olson) - The resident’s primary concern was their newly constructed concrete driveway and whether or not it would be impacted. It was pointed out to the resident that the curbs stop is along the edge of the driveway, and the replacement of the water service and sanitary sewer service would impact the driveway. They were told the driveway would be replaced in-kind, at full width, and that an attempt would be made to match the sawcut joint type. - They were also notified that the pipe tree would need to be removed, and they were fine with that and asked if they could keep the wood for firewood. They were told they could keep the wood and that they should communicate that with the field staff during tree removals.
