City of Lakeville Planning Department Memorandum To: Planning Commission From: Frank Dempsey, Associate Planner Date: May 15, 2020 Subject: Packet Material for the May 21, 2020 Planning Commission Meeting Agenda Item: The Preserve preliminary plat Action Deadline: July 31, 2020 BACKGROUND Representatives of Progressive, LLC have submitted applications for a preliminary plat, rezoning, and variance to allow the development of 89 single-family residential lots be known as The Preserve. The area of the preliminary plat includes four metes and bounds described parent parcels consisting of 89 single-family home lots and five outlots totaling 81.92 acres. The Preserve preliminary plat is generally located northeast of Kenwood Trail (CSAH 50), west of 188th Street, east of 190th Street, Javelin Avenue and Javelin Way and north of Iteri Avenue and Inndale Drive. The request includes a rezoning of the property from RS-2, Single Family Residential District to RS-3, Single Family Residential District. A variance for buffer yard lot width for three lots is also proposed. The Preserve preliminary plat plans have been distributed to Engineering Division and Parks and Recreation Department staff, and the Parks, Recreation and Natural Resources Committee and the Dakota County Plat Commission.

Wenck Executive Summary Narrative 5-6-20 PLANNING ANAL YSIS REZONING The developer requests approval of a rezoning of the subject property from RS-2, Single Family Residential District to RS-3, Single Family Residential District consistent with the zoning of the single-family neighborhoods to the east, west and south of the proposed The Preserve plat. The RS-2 and RS-3 Districts are differentiated by requirements of minimum lot size and lot width. The RS-2 District requires 100-foot wide, 15,000 square foot lots. The RS-3 District requires 85-foot wide, 11,000 square foot lots. Exhibit A identifies the area of the property that includes The Preserve that would be rezoned from RS-2 to RS-3. The proposed RS-3 District zoning remains consistent with the low-density residential land classification in the 2040 Comprehensive Plan. Findings of Fact in consideration of the rezoning request is attached. VARIANCE Three side yard buffer lots abutting 190th Street are proposed to be less than the required 110 feet in width, ranging between 99.8 and 100.2 feet in width. Additional buffer yard width is required for all lots that abut major collector or higher classification roads. The proposed lot widths are generally consistent with the minimum lot width for a standard corner lot not abutting a major collector road. Staff and the developer’s engineer explored options in order to maintain the minimum 110-foot wide side yard buffer lot width, but in doing so it would require shifting 190th 3 Street further north directly impacting the minimum lot depth requirement of the 12 buffer yard lots on the north side of 190th Street. Shifting the lots north would also result in the removal of additional trees that are now proposed to be saved in the area north of 190th Street. The landscape plan proposes additional landscaping for these lots to increase and maximize the effectiveness of the screening buffer. The three lots subject to the requested lot width variance will still be subject to the required buffer yard setback of 30 feet from the side yard abutting 190th Street. Findings of Fact in consideration of the variance request is attached. PRELIMINARY PLAT Existing Conditions. The development site consists of four parcels that included a single family home and accessory buildings that were removed in 2019. The land had historically been used for agricultural purposes until approximately the early 1990’s. The properties include large stands of mature trees and wetlands. Topography includes moderately sloping terrain from north to south. Many of the existing trees near the northeast portion of the preliminary plat appear as mature trees on aerial photographs since 1937. Many are proposed to be preserved as part of the proposed preliminary plat. Historic aerial photos also indicate that portions of the 80-acre property have been farmed until sometime around the early 1990’s. Consistency with the Comprehensive Plan. The proposed preliminary plat is located in Planning District 4 of the proposed 2040 Comprehensive Plan. Planning District 4 guides the subject property as low-density residential development where city sewer is available as well as restricted development consistent with the wetlands located on the property. Zoning and Adjacent Land Uses. The Preserve preliminary plat area is currently zoned RS-2. The developer proposes to rezone the property to RS-3 consistent with other single-family zoned properties in the area , while remaining within the low-density residential land use guided in the 2040 Comprehensive Plan. Adjacent single-family home developments to the west, south and east were developed between 2002 and 2013. Adjacent land uses and zoning are as follows: North – Single-Family Homes on large parcels and 185th Street (CSAH 60) (RS-2 District) East – Single-Family Homes (RS-3 District) South – Single-Family Homes (RS-3 District) West – Single-Family Homes and Kenwood Trail (CSAH 50) (RS-3 District) Consistency with the Capital Improvement Plan (CIP). City streets, sanitary sewer and water improvements for the area of The Preserve will be financed and constructed by the developer. The development costs associated with The Preserve development are not programmed in the 2020– 2024 CIP. 4 Premature Subdivision Criteria. A preliminary plat may be deemed premature if any of the criteria listed in Chapter 10-2-4-1 of the Subdivision Ordinance exist. Eligible criteria pertain to a lack of adequate: drainage, water, streets, sanitary sewer, and public service capacity (police and fire protection). The other pertinent criteria pertain to inconsistencies with the City Comprehensive Land Use and Capital Improvement Plans (discussed above). Staff review of The Preserve preliminary plat against these criteria finds that it not a premature subdivision. Density/Average Lot Size. The Preserve preliminary plat consists of 89 single-family lots on 81.92 acres. This results in a gross density of 1.08 units per acre. Excluding the 6.16 acre 190th Street major collector street right-of-way, wetlands and wetland buffers/public open space and stormwater management ponds, the net buildable area is 38.22 acres with a net density of 2.33 units per acre. Single-family lot sizes within The Preserve preliminary plat range from 11,009 square feet to 26,379 square feet in area. SINGLE-FAMILY LOT REQUIREMENTS Lots/Blocks. The following minimum single-family lot size requirements of the RS-3, Single- Family Residential District pertain to The Preserve preliminary plat, except for the identified lots abutting 190th Street for which a variance is proposed for buffer yard lot width: Lot Area (Interior) Lot Area (Corner) Lot Width (Interior) Lot Width (Corner) Lot Depth (Abutting 190th Street) RS-3 11,000 s.f. 12,500 s.f. 85 feet 110 feet 150 feet Setbacks. The following minimum requirements for single-family building setbacks in the RS-3 District pertain to The Preserve preliminary plat: Front Yard Side Yard (Interior) Side Yard (Corner) Rear Yard Rear/Side Yard (Buffers) RS-3 30 feet 10 feet 20 feet 30 feet 50 feet (rear) 30 feet (side) The proposed house pads shown on The Preserve grading, drainage and erosion control plan indicate that side and rear yard setback requirements can be met except for Lot 1, Block 4; Lot 1, Block 5; and Lot 9, Block 6. These are the buffer yard lots for which the variance is proposed. The building pad setbacks for the three variance lots shall be amended prior to City Council consideration of the preliminary plat. All 89 single-family lots have adequate building pad areas that meet setback requirements for principal structures. Outlots. There are five outlots totaling 37.07 acres in The Preserve preliminary plat. The use of the proposed outlots will be as follows: 5 Outlot A – 0.39 acres consisting of wetland and wetland buffer area to be deeded to the City with the final plat. Outlot B – 1.98 acres consisting of wetland, wetland buffer area, and a water quality corridor to be deeded to the City with the final plat. Outlot C – 17.16 acre outlot consisting of wetland, wetland buffer area, and stormwater basins to be deeded to the City with the final plat. Outlot D – 11.6 acre outlot consisting of stormwater basins, wetland and wetland buffer area, and a greenway corridor trail to be deeded to the City with the final plat. Outlot E – 5.94 acre outlot consisting of wetland and wetland buffer, greenway corridor trail, and tree preservation areas as preserved public park and open space to be deeded to the City with the final plat. Streets. The following is a summary of streets proposed with The Preserve preliminary plat. Additional detailed information is outlined in the Engineering Division memorandum dated May 13, 2020. 188th Court – 188th Court will be a cul-de-sac street extending east from Ixonia Avenue. The street will be constructed within a 60-foot wide right-of-way with a 32-foot wide street. There will be no sidewalk constructed within 188th Court. The cul-de-sac complies with the minimum required length of 150 feet and the maximum required length of 600 feet. 188th Street – 188th Street currently terminates at the west end of the Spring Hill Third Addition plat near the northeast corner of the proposed The Preserve preliminary plat. 188th Street will extend west with two lots fronting the north side of the street before turning south as Ivorra Avenue. The existing temporary cul-de-sac will be removed and 188th Street will continue the 60-foot wide right-of-way and 32-foot wide street with a five-foot wide concrete sidewalk along the north side of the street and west side connection of Ivorra Avenue. 189th Street – 189th Street will connect Ivorra Avenue and Ixonia Avenue. 189th Street will be constructed within a 60-foot wide right-of-way with a 32-foot wide street with a five-foot wide sidewalk on the north side of the street. 190th Street – 190th Street is a major collector within the south half of the property. 190th Street to the east of The Preserve is a 40-foot wide street within a 100-foot wide right of way. The preliminary plat plans for The Preserve shows the same right-of-way and street width continuing west until it intersects with Kenwood Trail opposite Jordan Trail, consistent with the Comprehensive Transportation Plan. Five-foot wide concrete sidewalks or bituminous trails will be constructed on both sides of 190th Street. Inndale Drive –Inndale Drive is a residential street that will be extended north from The Greenway neighborhood south of The Preserve to connect to 190th Street. The existing temporary cul-de-sac at the north end of Inndale Drive will be removed. Three lots will be 6 developed on either side of the Inndale Drive extension. Inndale Drive will be constructed within a 60-foot wide right-of-way and a 32-foot wide street consistent with the existing portion of Inndale Drive in The Greenway. Sidewalk was not constructed within The Greenway development so sidewalk will not be constructed along Inndale Drive within The Preserve north to 190th Street. Iteri Avenue – Iteri Avenue is a residential street that will be extended slightly north from The Greenway neighborhood and will end in a permanent cul-de-sac within The Preserve plat with no connection to 190th Street due to the discovery of soils contamination within that area of The Preserve plat. Sidewalk was not constructed within The Greenway development so sidewalk will not be continued into the permanent cul-de-sac. The temporary cul-de-sac constructed with The Greenway 4th Addition in 2011 and now located partly on the lots addressed as 19062 and 19063 Iteri Avenue shall be removed and the impacted areas of the two lots in The Greenway shall be restored by the developer of The Preserve. A financial security will be submitted by the developer for removal of the temporary cul-de-sac and restoration of the lots. Ivorra Avenue – Ivorra Avenue will connect 188th Street to 189th Street. The street will transition to 189th Street which will then connect to Ixonia Avenue. Ivorra Avenue will be a residential street constructed within a 60-foot wide right-of-way and a 32-foot wide street with a 5-foot wide concrete sidewalk along the west side of the street. Ivorra Court – Ivorra Court will be a short 150-foot deep cul-de-sac with four lots and will extend off the south side of 190th Street. Ivorra Court will include a 60-foot wide right-of-way with a 32- foot wide street without sidewalks. Ixonia Avenue – Ixonia Avenue is a minor collector street that will eventually connect 190th Street and 185th Street (CSAH 60) consistent with the Comprehensive Transportation Plan when the properties north of The Preserve develop in the future. Ixonia Avenue will eventually be a full access movement intersection at 185th Street. Ixonia Avenue is a 40-foot wide street within an 80-foot wide right of way with five-foot wide concrete sidewalks on both sides of the street. The preliminary plat shows the required amount of right-of-way to be dedicated with the final plat. Five-foot wide concrete sidewalks will be constructed on both sides of Ixonia Avenue. The developer shall install a sign at the north terminus of Ixonia Avenue that states “Future Road Extension.” Javelin Avenue – Javelin Avenue will be a residential street located within Stone Ridge 1st Addition. Javelin Avenue will be constructed within a 60-foot wide right-of-way and a 32-foot wide street with a five-foot wide concrete sidewalk along the south side of the street. The current temporary cul-de-sac at the end of Javelin Avenue will be removed with the second phase of the development. Javelin Avenue will transition into Javelin Path allowing connection to Javelin Way and 190th Street. Javelin Path – Javelin Path will be a residential street transitioning from Javelin Avenue and will be constructed within a 60-foot wide right-of-way and a 32-foot wide street with a five-foot wide 7 concrete sidewalk along the west side of the street. Javelin Path will connect Javelin Avenue from the north to Javelin Way to the south. Javelin Way – Javelin Way will extend east from the temporary turnaround in Stone Ridge 1st Addition and will connect to 190th Street to the south. The temporary turnaround on the property at 18826 Javelin Way at the east terminus of Javelin Way in Stone Ridge 1st Addition will be removed by the developer. The property where the temporary cul-de-sac is now located shall be restored when Javelin Way is extended to the east. A financial security will be submitted by the developer for removal of the temporary turnaround and restoration of the lot on which it is now located. Javelin Way is a residential street constructed within a 60-foot wide right-of-way and a 32-foot wide street with a five-foot wide concrete sidewalk along the south and west sides of the street. Kenwood Trail (CSAH 50) – Kenwood Trail (CSAH 50) abuts approximately 480 feet of The Preserve plat near the southwest corner of the site. Kenwood Trail is classified as a minor arterial roadway in the Comprehensive Transportation Plan. Kenwood Trail requires 75 feet of half right-of-way adjacent to the plat. The plat will dedicate the 75 feet of right-of-way required by Dakota County. A pedestrian trail was installed along the north side of Kenwood Trail with the Kenwood Trail improvement project in 2018. All streets meet the minimum width and design requirements of the Subdivision Ordinance. Grading, Drainage, Erosion Control, and Utilities. Proposed grading, drainage, erosion control, and utilities for The Preserve preliminary plat is shown on the grading, drainage and erosion control, and utility plans. The plans are outlined and discusse d in the May 13, 2020 engineering report prepared by Alex Jordan, Assistant City Engineer and Mac Cafferty, Environmental Resources Manager. The Engineering Division recommends approval of the preliminary plat. Tree Preservation. A tree preservation plan was submitted by the developer. The tree preservation plan identified 3,756 significant trees located within The Preserve preliminary plat boundaries. The tree preservation plan proposes to save 1,543 (41%) of the significant trees on site . Mac Cafferty, Environmental Resources Manager has reviewed the tree preservation plan. His comments are included in the May 30, 2019 engineering report. Wetlands. A wetland delineation was completed and approved on October 16, 2019. The wetland delineation identified 12 wetlands on site totaling 16.09 acres. The information and data have been incorporated into the preliminary plat plans. Mac Cafferty, Environmental Resources Manager, has reviewed the wetland delineation report. His comments regarding wetland preservation and impacts are included in the May 13, 2020 engineering report. Park Dedication. The City’s 2015 Parks, Trails, and Open Space Plan does not call for a neighborhood park within this development. Outlot E will include 4.95 acres that can be used for play pod areas that will abut up to The Preserve Greenway corridor trail. These play pod areas 8 will not be developed with field facilities, but a small playground may be possible on the site. Specifics related to future play pod areas will be determined at a later date following neighborhood input and suggestions. A combination of land dedication and cash payment will be used to satisfy the park dedication requirements at the time of final plat approval for the future phases of the project. The Parks, Recreation and Natural Resources Committee will review the preliminary plat at their May 20, 2020 meeting. Their comments will be forwarded to the Planning Commission at the public hearing. Sidewalks/Trails. The developer will construct 5-foot wide concrete sidewalks as required along one side of all streets in the development except cul-de-sacs, as noted in the planning report. The City’s 2015 Parks, Trail and Open Space Plan identifies bituminous trails connecting the Ipava Greenway Corridor north toward 185th Street. One segment of the greenway trail is proposed to extend west from near 188th Street into The Preserve neighborhood, then extend westerly through the wooded area to connect to Ixonia Avenue and eventually to 190th Street and the pedestrian trail on Kenwood Trail. The developer is negotiating with the owner of the property adjacent to the northeast corner of the plat to acquire the necessary trail easement to make the trail connection from 188th Street into The Preserve development. A sketch for the possible trail is attached. Another trail will connect to the Ipava Greenway trail in The Greenway neighborhood to the south. A trail crossing will be located at the intersection of Ixonia Avenue and 190th Street. Subdivision Monument Sign. A monument sign has not been identified with The Preserve preliminary plat. Any future monument sign shall meet Zoning Ordinance requirements. MUSA. The Preserve preliminary plat area is located within the current Metropolitan Urban Service Area (MUSA) and is able to connect to adjacent City sewer and water utilities. Ghost Plat. A conceptual lot and street layout (ghost plan) sketch was submitted for City staff review for the two 10 acre properties north of The Preserve and aligned with the proposed extension of Ixonia Avenue. The sketch includes the extension of Ixonia Avenue north to 185th Street. The future development of the properties north of The Preserve must include the extension of Ixonia Avenue north to 185th Street. Development Phasing Plan. The phasing plan proposes two phases of development commencing on the east side of the plat west to include Ixonia Avenue. The second phase proposes development of 190th Street and the west half of the plat adjacent to Stone Ridge 1st Addition. Development phasing is anticipated to begin Phase II during the 2021 – 2022 construction season. Development phasing is conceptual and may be subject to change by the developer upon submittal of future final plat phases. The development phasing plan is attached. 9 Overhead Utilities. Overhead electric lines and poles are located within the site on the parent parcels. The Developer is required to remove the overhead lines and poles with the final plat. All utility lines will be placed underground consistent with City Code requirements. Independent School District No. 194. ISD 194 received notice of the public hearing and the plans for the proposed preliminary plat. No comments were received. Plat Commission. The Dakota County Plat Commission reviewed and approved the preliminary plat at their June 17, 2019 meeting. The Plat Commission letter is attached. Identified Landfill and Soils Contamination/Mitigation Summary. As required by the Subdivision Ordinance, Progressive Land hired the services of a company to determine the conditions of soils on the property to identify variable soils and their suitability for the proposed development layout and street construction. A Phase I environmental report followed by a soil testing report was completed for the site. Two areas of concern of approximately 6.8 acres within the preliminary plat was identified that warranted further study. The Phase I environmental review identified an area near the center of the property as a likely dump area that included an old vehicle, household appliances, and various metal scraps. The testing identified an uncontrolled landfill of construction and other waste materials on-site likely dating from the 1980’s, which apparently pre-dates the most recent previous owner(s) of the property. In October 2019, Progressive Land hired the services of Wenck and Associates, Inc. (Wenck) to further investigate the scope and nature of the soils testing and landfill and determine contaminants at concentrations of potential concern within the proposed construction site. The testing identified evidence of elevated contamination in the soil and groundwater within the 6.8- acre landfill area. The additional testing that identified the older landfill area in the center of the property brought the total suspected landfill area to 11.4 acres. Wenck prepared a technical memo in November 2019, describing the nature of the landfill materials discovered. Wenck followed with a report dated February 20, 2020 which was submitted to the Minnesota Pollution Control Agency (MPCA). This was followed by a March 11, 2020 addendum to the February 20, 2020 environmental investigation work plan submitted to the MPCA. Based on the results of the study, a Response Action Plan (RAP) will be prepared and submitted to the MPCA for review and approval. The development improvements must be completed in accordance with the recommendations identified in the approved RAP. Progressive Land has filed a request to the MPCA for a Retroactive No Association Determination Letter for recognition that the landfill on the property was not a result of actions of Progressive Land. Neighborhood Meeting. The developer hosted an open house neighborhood meeting on Wednesday, June 19, 2019 at the Water Treatment Facility. Approximately 30 residents attended. Summary notes of the neighborhood meeting are attached. The reason for the delay between 10 June 19, 2019 and the public hearing for the preliminary plat was due primarily to the discovery of landfill materials on the property. RECOMMENDATION Planning Department staff recommends approval of The Preserve preliminary plat, rezoning, and variance subject to the following stipulations: 1. Implementation of the recommendations listed in the May 13, 2020 engineering report. 2. Park dedication shall be satisfied with a combination of land dedication and cash contribution paid with the final plat for each development phase. 3. The developer shall construct five-foot wide concrete sidewalks along one side of all streets, except cul-de-sacs, and bituminous trails as identified on the preliminary plat plans. 4. Outlots A-E shall be deeded to the City with the final plat. 5. Side yard building setback s for Lot 1, Block 4; Lot 1, Block 5; and Lot 9, Block 6 shall comply with 30-foot side yard buffer setback requirements in the RS-3 District. The building pads on the preliminary plat and grading plan shall be amended to comply with RS-3 District side yard buffer setbacks prior to City Council consideration of the preliminary plat. 6. Buffer yard landscaping shall be installed according to the approved landscape plan. A security for the buffer yard landscaping shall be submitted with the final plat. 7. Driveway access is not permitted onto 190th Street. 8. All new local utilities and any existing overhead service utilities located on the property shall be placed underground. 9. Any existing structures, fences, wells, and septic systems shall be removed with the development of this property. 10. The developer shall adhere to all environmental laws and regulations regarding soils contamination and site remediation. The development improvements must be completed in accordance with the recommendations identified in the approved Response Action Plan (RAP).

Approximately 30 residents were in attendance. Planning Department and Engineering Division staff were in attendance. The open house meeting was held between 5:30 PM and 7:00 PM at the Water Treatment Facility. The meeting was attended by the following individuals: •Joey Miller, representing Progressive, LLC •Steve Sauber, representing Progressive, LLC •Bob Wiegert, Progress Land Co. •John Bertelson, Progress Land Co. •Frank Dempsey, Associate Planner •MacCafferty, Environmental Resources Manager o Access and controls for construction traffic. Miller stated they will use the existing driveway access from Kenwood Trail as much as is feasible and no other alternative is available due to soil/weather conditions.

The plat is adjacent to CSAH 50 (Kenwood Ave.), and is therefore subject to the Dakota County Contiguous Plat Ordinance. Lakeville staff, Frank Dempsey, provided an overview of the preliminary plat. The preliminary plat showed a connection of 190th Street to CSAH 50. The plat also showed numerous local street connections, including a connection through the extension of Ixonia Street to the north, and eventually connecting to CSAH 60. A small parcel of land located at the connection of 190th Street and CSAH 50 is already County ROW and may not need to be dedicated. The Plat Commission has approved the preliminary plat. The Ordinance requires submittal of a final plat for review by the Plat Commission before a recommendation is made to the County Board of Commissioners. Traffic volumes on CSAH 50 are 18,600 ADT and are anticipated to be 27,000 ADT by the year 2030. These traffic volumes indicate that current Minnesota noise standards for residential units could be exceeded for the proposed plat. Residential developments along County highways commonly result in noise complaints. In order for noise levels from the highway to meet acceptable levels for adjacent residential units, substantial building setbacks, buffer areas, and other noise mitigation elements should be incorporated into this development. No work shall commence in the County right of way until a permit is obtained from the County Transportation Department and no permit will be issued until the plat has been filed with the County Recorder’s Office. The Plat Commission does not review or approve the actual engineering design of proposed accesses or other improvements to be made in the right of way. Nothing herein is intended to restrict or limit Dakota County’s rights with regards to Dakota County rights of way or property. The Plat Commission highly recommends early contact with the Transportation Department to discuss the permitting process which reviews the design and may require construction of highway improvements, including, but not limited to, turn lanes, drainage features, limitations on intersecting street widths, medians, etc. Please contact Butch McConnell regarding permitting questions at (952) 891-7115 or Todd Tollefson regarding Plat Commission or Plat Ordinance questions at (952) 891-7070.

Tollefson Secretary, Plat Commission c: EXHIBIT O Technical Memo Wenck | Colorado | Georgia | Minnesota | North Dakota | Wyoming Toll Free 800-472-2232 Web wenck.com To: Mr. Steve Sauber, Progressive, LLC From: Ms. Michelle Hosfield, Wenck Associates, Inc. Date: November 12, 2019 Subject: Environmental Sampling Results – The Preserve, 19030 Kenwood Trail, Lakeville, MN On October 15, 2019, Wenck Associates, Inc. (Wenck) in conjunction with Progressive, LLC and Country Joe Homes completed environmental sampling and observation activities at the proposed residential development known as The Preserve. The Preserve is located at 19030 Kenwood Trail in Lakeville, Minnesota (the Site). Based on information provided from a geotechnical exploration at the Site, dump materials were noted by Haugo GeoTechnical Services, LLC (Haugo) at test pit TP-14 located southeast of an existing house and driveway. The scope of work proposed by Wenck was to obtain a snapshot of the horizontal and vertical limits of the dump, to observe and document the type of debris buried and to collect soil and groundwater samples for characterization. Single-family homes and roadways are proposed in this area. The investigation activities included oversight of 17 test pits around TP-14, collection of 4 soil samples and 1 groundwater sample for laboratory analysis, field screening of soils and preparation of this report. Investigation Activities During investigation activities, soils were logged by a Field Scientist (FS) during test pit excavation. Each test pit was flagged in the field and surveyed by others. The test pit locations are depicted on Figure 1. The soils were classified, logged and screened with a photoionization detector (PID) equipped with a 10.6 eV lamp. The PID measures volatile organic compounds (VOCs) in the parts per million (ppm) range. Prior to using the PID, the unit was calibrated using an isobutylene gas. Soil samples were collected for laboratory analysis at the interval with the highest PID reading or within the debris layer. Soil sample locations were selected across the Site to achieve good spatial coverage. In addition, one groundwater sample was collected from test pit TP-10 to collect data for potential dewatering purposes. The soil and groundwater samples were placed in laboratory-provided containers, labeled and placed in a cooler on ice under proper chain-of-custody procedures. The samples were submitted to TestAmerica Laboratory for analysis of diesel range organics (DRO), gasoline range organics (GRO), VOCs, polynuclear aromatic hydrocarbons (PAHs) and the 8 Resource Conservation and Recovery Act (RCRA) metals. Soil Results Elevated PID readings above 10 ppm were not recorded on the test pit logs. All of the PID readings were below 1.0 ppm. Soils along the south side of the dump area in test pits TP-1, TP-2, TP-5, TP-6, TP-7 and TP-8 had 1 to 11 feet of fill soils consisting of silty sand, sandy clay and clayey sand with large pieces of concrete and asphalt. Organic peat or organic EXHIBIT P Mr. Steve Sauber Progressive, LLC November 12, 2019 2 N:\Technical\7956 Schaefco\01\Tech Memo_The Preserve 111219.docx clayey soils were encountered at the bottom of the test pits. Test pit TP-5 also had metal mixed in with the debris. Test pits along the existing driveway on the west side of the presumed dump area, TP-3, TP-4, TP-15 and TP-17, showed silty sand fill soils with concrete, metal, plastic, brick and wood. Test pit TP-4 had buried car parts and clay pipe and test pit TP-17 had evidence of roofing materials and foam. In the central portion of the dump area, test pits TP-10, TP-11 and TP-16 showed clayey sand and silty sand fill soils with concrete, metal, bituminous, wood, rubber pieces and tires. In test pit TP-16, roofing materials and foam were noted in the debris layer. On the east side of the presumed dump area, test pits TP-8 and TP-9 showed clayey sand and sandy clay with bituminous pieces. Wood paneling was noted in test pit TP-9. Surficial evidence of dumping was observed near test pit TP-15 on the far east side of the dump. In TP-15, fill soils consisted of silty sand with concrete, metal, plastic and wood to a depth of 6 feet below grade. A layer of ash was also noted in test pits TP-16 and TP-17 between 2 and 3 feet below grade. Test pit logs are included as Attachment 1. Wenck test pit TP-13 and Haugo test pits TP-15 through TP-17 did not show evidence of debris on the north side of the dump. Test pit TP-12 had trace concrete pieces within the fill soils. Soil samples for laboratory analysis were collected from test pits TP-3 (0-2’), TP-15 (0-4’), TP-16 (6-8’) and TP-17 (2-3’). Soil investigation data compared detected concentrations of RCRA metals, VOCs and PAHs to the Minnesota Pollution Control Agency’s Tier 1 Residential and Tier 2 Industrial Soil Reference Values (SRVs). Additionally, MPCA Tier 1 Soil Leaching Values (SLVs) were referenced to evaluate the potential risk to groundwater at the Site from the soil-to-groundwater leaching pathway. There are no established MPCA SRVs or SLVs for DRO and GRO. However, the criteria used for off-site reuse of soils as unregulated fill is 100 milligrams per kilogram (mg/kg). Table 1 shows a summary of the soil analytical results. The laboratory analytical report is included as Attachment 2. RCRA Metals The analytical results showed elevated concentrations of selenium in test pits TP-3 and TP- 15 above the MPCA Tier I SLV of 2.6 mg/kg. Selenium ranged from 22.1 to 30.7 mg/kg. DRO/GRO In test pits TP-3 and TP-16, DRO was detected at 143 and 2,820 mg/kg, respectively. GRO was not detected in the collected soil samples. PAHs In test pit TP-16 (6-8’), benzo(a)pyrene was detected above the MPCA Tier I Residential Soil Reference Value (SRV) of 2 mg/kg at a concentration of 48.7 mg/kg. Naphthalene was detected at 6.46 mg/kg, which is above the MPCA SLV of 4.5 mg/kg. Benzo(a)pyrene (BaP) equivalent concentrations were calculated to estimate the aggregated carcinogenic potential of PAHs relative to benzo(a)pyrene. The benzo(a)pyrene equivalent is calculated using the sum of the products of the respective relative potency slope factors multiplied by the compound’s soil concentration. In the soil sample from test pit TP-16, the BaP was calculated at 70.2682 mg/kg, which is above the MPCA Residential SRV of 2 mg/kg. Mr. Steve Sauber Progressive, LLC November 12, 2019 3 N:\Technical\7956 Schaefco\01\Tech Memo_The Preserve 111219.docx VOCs Naphthalene was the only VOC constituent detected in the collected soil samples. Naphthalene was detected in TP-16 (6-8’) below the MPCA Residential SRV. Groundwater Results Groundwater investigation data analysis compared detected concentrations of VOCs and PAHs to the Minnesota Department of Health (MDH) Health Risk Limits (HRLs) and Health Based Values (HBVs) to assess potential human health risks from exposures to chemicals in groundwater. There are no established HRLs or HBVs for GRO and DRO; however, 1,000 micrograms per liter (ug/L) is used as an indication of additional assessment and/or remediation in MPCA Petroleum Remediation Program (PRP) Guidance Document 4-01, Soil and Groundwater Assessments Performed During Site Investigations. Table 2 summarizes the groundwater analytical results. A groundwater sample was collected from test pit TP-10 using a disposable bailer. Results showed a detection of barium at 283 ug/L. The established HRL for barium is 2,000 ug/L. Naphthalene was detected at 5.43 ug/L, which is below the HRL of 70 ug/L. DRO was detected at 475 ug/L and GRO was not detected above laboratory detection limits. In addition, benzo(a)pyrene was detected in the groundwater sample above the HRL of 0.1 ug/L at a concentration of 0.591 ug/L. Conclusions Based on the information provided to date, the fill soils on the Site appear to contain debris to depths of 10 to 11 feet below grade. Some bigger pieces of asphalt and concrete could be separated from the soils and potentially hauled to a demolition landfill or crushed on-site to be used as road base, depending on the recommendations of a geotechnical engineer. If the fill soils are excavated, they would need to be properly disposed in a landfill based on the concentrations of DRO, selenium and PAHs found above regulatory limits. Depending upon the amount of fill soils, additional soil sampling would be required to fully characterize the soil for landfill disposal. Groundwater at one location is impacted with DRO and benzo(a)pyrene above the MDH HRL. Additional characterization would be required if dewatering was necessary at the project site. Typically, impacted groundwater can be pumped to a sanitary sewer system for disposal during dewatering activities. Permits with the City and Met Council would need to be obtained for any dewatering activities to the sanitary sewer system. Soil vapor samples were not collected as part of this scope of work. Vapor intrusion has become a “hot button” issue with the MPCA, especially at development sites. In this case, VOCs, methane and hydrogen sulfide would be the chemicals of concern when working with a dump site. Soil vapor results have defined the horizontal clean-up buffers that need to be in place during redevelopment and may reach up to a radius of 200 feet. Soil vapor sampling may be warranted if the dump site will be redeveloped or if residential lots will be located near this area. Mr. Steve Sauber Progressive, LLC November 12, 2019 4 N:\Technical\7956 Schaefco\01\Tech Memo_The Preserve 111219.docx Recommendations Based on the field observations and laboratory analysis of the collected soil and groundwater samples from the Site, Wenck submits the following recommendations: 1. The petroleum and non-petroleum detections at the Site shall be reported to the Minnesota State Duty Officer. 2. Enroll the Site into the MPCA Voluntary Investigation and Cleanup (VIC) and Petroleum Brownfields Programs. Apply for a Retroactive No Association Determination Letter from the VIC Program related to the non-petroleum releases in the soil and groundwater at the Site. Apply for a General Liability Letter for the identified petroleum release at the Subject Property. 3. If site development is still an option, additional soil, groundwater and soil vapor testing is warranted. The testing would further characterize the media. The results can then be used to prepare a Response Action Plan for the management of contaminated media and the proposed development.

Receipt The samples were received on 10/16/2019 10:10 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 2 coolers at receipt time were 0.8º C and 1.1º C. GC/MS VOA Method 8260B: The continuing calibration verification (CCV) associated with batch 310-257170 recovered above the upper control limit for Chloroethane(59.9%D). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The following sample is impacted: (CCV 310-257170/4). Method 8260B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch 310-257160 and analytical batch 310-257170 recovered outside control limits for the following analytes: Acetone. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch 310-257160 and analytical batch 310-257170 recovered outside control limits for the following analytes: Bromoform. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260B: Surrogate recovery was outside acceptance limits for the following matrix spike/matrix spike duplicate (MS/MSD) sample: (310-167552-D-10 MS). The parent sample's surrogate recovery was within limits. The MS/MSD sample has been qualified and reported. Method 8260B: The surrogate recovery for the CCV and LCS associated with analytical batch 310-257528 was outside the upper control limits. Method 8260B: The laboratory control sample (LCS) for analytical batch 310-257708 recovered outside control limits for the following analytes: 1,2,4-Trimethylbenzene and sec-Butylbenzene. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC/MS Semi VOA Method 8270D SIM: The following samples were diluted due to the nature of the sample matrix: TP-3 (0-2') (310-167565-1), TP-15 (0-4') (310-167565-2), TP-16 (6-8') (310-167565-3), TP-17 (2-3') (310-167565-4), TP-10 (310-167565-5) and (310-167654-A-8-C). Elevated reporting limits (RLs) are provided. Method 8270D SIM: The following samples were diluted due to the nature of the sample matrix: (310-167654-A-6-C), (310-167654-A-6-A MS), (310-167654-A-6-B MSD), (310-167654-A-8-A MS) and (310-167654-A-8-B MSD). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC VOA Method WI-GRO: The method blank for batch 257652 contained Wisconsin GRO above the reporting limit (RL). None of the samples associated with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not performed. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC Semi VOA Method WI-DRO: The laboratory control sample (LCS) for preparation batch 310-257080 and analytical batch 310-257490 recovered outside acceptance limits for DRO. There was insufficient sample to perform a re-extraction or re-analysis; therefore, the data have been Eurofins TestAmerica, Cedar Falls Page 3 of 64 10/23/2019 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Case Narrative Client: Wenck Associates, Inc Job ID: 310-167565-1 Project/Site: The Preserve Job ID: 310-167565-1 (Continued) Laboratory: Eurofins TestAmerica, Cedar Falls (Continued) reported.

(Wenck) was authorized by Progressive, LLC to prepare this Investigation Work Plan (the Work Plan) for environmental investigation activities at the proposed development known as The Preserve. The Preserve is an approximately 82-acre agricultural site that is being developed with single-family residential homes, associated roadways, utilities and stormwater infrastructure. A portion of The Preserve, approximately 6.8-acres, is affected by an unpermitted dump (the Site). The dump area is located adjacent to the address of 19030 Kenwood Trail in Lakeville, Dakota County, Minnesota. The focus of this investigation will be specifically on the 6.8-acre site. The Site location is depicted in Figure 1. A Site Detail Map and Existing Conditions Map are included as Figures 2 and 3, respectively. The Existing Conditions Map shows the outline of the 6.8- acre Site. In October 2019, Wenck conducted environmental sampling in the area of the identified dump based on a geotechnical evaluation by Haugo GeoTechnical Services, Inc. The purpose of the initial sampling was to provide an initial evaluation of potential environmental impacts at the Site as well as begin to determine the approximate vertical and horizontal extents of the waste material. The investigation activities revealed elevated petroleum, selenium and polynuclear aromatic hydrocarbons (PAHs) in soil and groundwater within the 6.8-acre dump area. In January 2020, Progressive, LLC pursued a “Retroactive No Association Determination” Letter from the Minnesota Pollution Control Agency (MPCA) for known impacts at the Site. The Site was assigned MPCA Site ID BF0001384. Based on a conference call with MPCA Project Managers, Mr. David Knight and Mr. Ryan Lundgren, Wenck and Progressive, LLC, it was determined that an Investigation Work Plan would be necessary to further characterize the Site based on the current development plan. The Work Plan would be submitted to the MPCA for review and comment. After the investigation activities are completed, as outlined in this Work Plan, a Response Action Plan would be developed for MPCA approval and followed during construction activities. The purpose of the Work Plan is to outline future investigation activities to determine if the Site has been impacted by hazardous substances, pollutants, or contaminants at concentrations of potential concern within the proposed construction areas at the Site. The potential for such impact has been identified in past investigations documented in 2019. February 2020 2-1 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx 2.0 Site Description The Subject Property is located in a rural and residential area in Lakeville, Dakota County, Minnesota. Site Address/Location Address: 19030 Kenwood Trail City: Lakeville County: Dakota State: Minnesota Township: Range: Section: 114 North 20 West South ½ of 18 Property Information Size: 6.8 acres Property Identification Number: Southern portion of 220180060011 Improvements There are no improvements on the Site. A gravel driveway adjoins the west property boundary. Use of the Property Current Use: The Site is currently vacant. The site is occupied by low-lying areas and dense wooded areas. Past Use: The February 2019 Phase I ESA by Haugo GeoTechnical Services, LLC (Haugo Phase I ESA 2019) and the aerial photographs included with the ESA show the current house adjacent to the west of the Site in the 1937 aerial photograph. A barn is located in the northwest corner of the Site with the majority of the Site being agricultural land. The barn was present on the aerial photographs until 2010. Filling activities first appeared on the 1987 aerial photograph with signs of grading from the farmstead driveway to the east. Dense tree growth and vegetation appeared within the dump area on the 1997 aerial photograph. Ownership and Operation of the Property Current Ownership & Operation: The Site is currently owned by Progressive, LLC and is currently vacant land. The Site location is depicted in Figure 1. A Site Detail Map showing the Site boundaries is provided in Figure 2. February 2020 2-2 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx 2.1 CURRENT USE OF ADJOINING PROPERTIES The following land uses were noted on adjoining properties: Direction Description North Unimproved land and single-family residences further north along County Road 60 (185th Street West). South Single-family residences and Kenwood Trail East Unimproved land and single-family residences along Irvona Avenue West Unimproved land and single-family residences along Javelin Avenue and Javelin Way 2.2 PHYSICAL SETTING 2.2.1 Topography The ground surface elevation is approximately 1,040 feet on the north side of the Site and 1,030 feet on the south side of the Site. The topography along the south end of the dump shows a noticeable decline down to the property line. Delineated wetlands are noted on Figure 3 along the south property boundary and east half of the Site. Numerous wetlands exist on the property in the low-lying areas. 2.2.2 Geology According to the 2019 Haugo Phase I ESA and published references, surficial geology at the Site consists of glacial till. The glacial till is identified as thin Des Moines lobe till over pre- Wisonsinan drift (Howard C. Hobbs et al, 1990). Bedrock in the vicinity of the Site consists of the St. Peter Sandstone. The upper half to two thirds of the St. Peter Sandstone is described as fine- to medium-grained quartzose sandstone. The lower portion of the formation contains multicolored beds of sandstone, siltstone and shale with interbeds of very coarse sandstone (John H. Mossler et al, 1990). Depth to bedrock ranges from 151 to 250 feet below ground surface (Bruce A. Bloomgren et al, 1990). 2.2.3 Hydrogeology The general direction of regional groundwater flow in the area of the Subject Property is noted to the south-southwest towards Marion Lake. The groundwater elevation is approximately 1,000 to 1,025 feet above mean sea level (Barbara M. Palen, 1990). Local groundwater conditions may vary due to surface water features, perched groundwater conditions or artificially created drainage systems. Based on geotechnical boring logs by Haugo, the Site’s surficial groundwater table at boring SB-5 (east of the Site) is at an elevation of approximately 1,036 feet corresponding to approximately 8 feet below grade.

(2019 Wenck Technical Memo) 3.1 2019 HAUGO PHASE I ESA A Phase I ESA was completed by Haugo Geotechnical Services, LLC, dated February 4, 2019. The Phase I ESA included the entire 82-acre property that is proposed to be developed. The Phase I ESA includes the 6.8 acres of property that is part of this Work Plan. A copy of the Phase I ESA is included as Appendix A. One Recognized Environmental Condition (REC) was identified in the 2019 Haugo Phase I ESA report, “A dump area was observed in a wooded area near the center of the property. The dump area included but was not (limited to) an older model vehicle (old car), household appliances, wire fencing, and pieces or scraps of metal. A review of historical imagery indicates that this dump area has been present since at least the mid-1960s. It is unclear the extent and depth of this dump area.” Haugo also identified one domestic well located east of the existing house. A septic system drain field was identified west of the house. In addition, there was discussion of removing the existing structures that could potentially contain asbestos building materials and/or hazardous materials that should be removed prior to demolition activities. 3.2 2019 HAUGO GEOTECH AND 2019 HAUGO TEST PITS In January 2019, Haugo installed 16 soil borings on the 82-acre property for geotechnical purposes. One soil boring, SB-4, was drilled within the 6.8-acre dump Site. Boring SB-4 was located in the northwest corner of the Site. Boring SB-4 encountered silty sand (topsoil) underlain by brown to gray silty clay to 7 feet below grade (bg). Silty clayey sand with gravel was encountered from 7 to 9 feet bg with sandy silt to 12 feet bg. Silty clayey sand, trace gravel was encountered to the end of the boring at 21 feet bg. No debris was noted in this boring log. Soil borings SB-3 and SB-5 were drilled west and east, respectively of the 6.8-acre Site. Boring SB-3 showed a little over 1 foot of silty sand (topsoil) underlain by lean clay to 4 feet bg. A mix of silty clayey sand and clayey sand, trace gravel was encountered to 9 feet bg. Silty clayey sand, trace gravel was encountered to the end of the boring to 21 feet bg. No debris was noted in this boring log. February 2020 3-2 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx Boring SB-5 showed 1 foot of silty sand (topsoil) and 1 foot of silty clay. Poorly graded sand with silt was encountered from 2 to 4 feet, underlain by clayey sand to 7 feet bg. Silty sand and sandy silt was encountered to 12 feet. Silty clayey sand was noted to the end of the boring at 21 feet. No debris was noted in this boring log. In addition to the soil borings, several test pits were conducted within the 82-acre project site by Haugo in August 2019. At the 6.8-acre Site, test pits TP-14 through TP-17 excavated and logged. Test pit TP-14 was conducted in the central portion of the Site and test pits TP- 15, TP-16 and TP-17 was located in the northwest corner of the Site. The draft test pit logs were reviewed by Wenck. A log for test pit TP-17 was not included in the draft submittal package. Test pit TP-14 showed fill material consisting of black to dark brown to brown clayey sand with concrete and bituminous debris to the bottom of the test pit at 8 feet bg. Test pit TP-15 showed clayey sand (topsoil) to 2 feet bg, underlain by poorly graded sand with silt to 5 feet bg. Sandy lean clay was encountered to the end of the test pit at 10 feet bg. No debris was encountered. Test pit TP-16 showed dark brown to black clayey sand (topsoil) to 2 feet, underlain by lean clay and sandy lean clay to 9 feet bg. No debris was encountered. A copy of the 2019 Haugo geotechnical report and draft test pit logs are included as Appendices B and C. Figure 3 shows the locations of the geotechnical borings and test pits. 3.3 2019 WENCK TECHNICAL MEMO Wenck was obtained by Progressive, LLC to conduct soil and groundwater sampling activities at the Site. On October 15, 2019, Country Joe Homes excavated test pits TP-101 through TP-117. These test pits were excavated around Haugo test pit TP-14. Wenck was on-site to log the test pits and screen the soils using a photoionization detector (PID). Soil samples were collected for laboratory analysis at the interval with the highest PID reading or within the debris layer. Soil sample locations were selected across the Site to achieve good spatial coverage. Soil samples were collected from test pits TP-103, TP-115, TP-116 and TP-117. In addition, one groundwater sample was collected from test pit TP-110. The soil and groundwater samples were analyzed for diesel range organics (DRO), gasoline range organics (GRO), Resource Conservation and Recovery Act (RCRA) metals, PAHs and volatile organic compounds (VOCs). Concentrations were compared to the MPCA Tier I Soil Reference Values (SRVs) and Soil Leaching Values (SLVs). The reuse criteria for DRO and GRO is 100 milligrams per kilogram (mg/kg). Soil results showed elevated selenium concentrations above the established SLV in test pit samples TP-103 (0-2’) and TP-115 (0-4’). DRO was detected above 100 mg/kg in samples TP-103 (0-2’) and TP-116 (6-8’). GRO was not detected in the collected soil samples. In sample TP-116 (6-8’) benzo(a)pyrene was detected above the Residential SRV and naphthalene was detected above the SLV. The calculated BaP equivalent was above the Residential SRV in test pit TP-116. February 2020 3-3 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx Groundwater results from test pit TP-110 showed DRO at 475 micrograms per liter (ug/L). Benzo(a)pyrene was detected above the Minnesota Department of Health (MDH) Health Risk Limit (HRL) of 0.1 ug/L at a concentration of 0.591 ug/L. The technical memo and supporting documents are included as Appendix C. February 2020 4-1 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx 4.0 Investigation Work Plan 4.1 FIELD INVESTIGATION RATIONALE The objective of this investigation Work Plan is to identify if soil, groundwater, and/or soil vapor impacts are currently present at the Site and to assess if the impacts are at concentrations of concern within the proposed construction areas. Impacts, if identified, will be comparted to MPCA Residential and Industrial SRVs, Tier I SLVs, Soil Vapor Intrusion Screening Values (ISVs), and the MDH HRLs. The impacts will be assessed against future land use with the decision to incorporate additional investigation activities or prepare a Response Action Plan (RAP) for construction. An Existing Conditions Plan is included as Figure 3. A Proposed Site Plan is included as Figure 4. Both figures 3 and 4 show the previous test pit and boring locations. Procedures for soil, groundwater, and soil vapor sampling activities will follow Wenck’s standard operating procedures. Methods and procedures are described below. 4.2 POTENTIAL CONTAMINANTS OF CONCERN A list of potential contaminants of concern (COCs) have been identified through historical report review. Total Resource Conservation and Recovery Act (RCRA) eight metals Polynuclear Aromatic Hydrocarbons (PAHs) Volatile Organic Compounds (VOCs) Diesel range organics (DRO) Gasoline range organics (GRO) Pesticides Laboratory methodologies that will be used during this investigation are as follows for soil and groundwater: Parameter Laboratory Methodology RCRA metals EPA Method 6010B/7471 PAHs EPA Method 8270 by SIM VOCs EPA Method 8260 DRO WI Method (gw)/Silica Gel Method (soil and groundwater) GRO WI Method Pesticides SW846 8081B Laboratory methodologies that will be used during this investigation for soil vapor are as follows: Parameter Parameter Laboratory Methodology Methane EPA Method 3C VOCs EPA Method TO-15 February 2020 4-2 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx 4.3 SOIL INVESTIGATION A series of eight (8) geoprobes will be drilled at the Site to determine the thickness of the debris layer and depth of native soils. Wenck will collect soil samples within the debris layer to characterize the soils for future reuse or disposal options. Gopher One Call will be notified. Utility lines buried at the Site will be located by the appropriate utility company and indicated on the ground surface. At this time, we don’t anticipate hiring a private utility locator. The eight (8) geoprobes will be drilled to depths of approximately 10 to 15 feet below grade depending upon the thickness of the debris layer. The goal of the drilling is to collect soil samples within the debris layer and the establish the thickness of the debris layer. During the advancement of the soil borings, soil samples will be collected for screening to boring termination. Equipment will be cleaned prior to arrival on-site. In addition, either new, cleaned equipment or equipment that is decontaminated between each soil boring will be used during drilling activities to eliminate the possibility of cross-contamination. A Field Geologist will be on-site to log the borings and to collect soil samples. Soil borings will be located during the field activities by the Field Geologists using a handheld GPS unit or will be staked in the field and surveyed by others. Soil samples will be screened for the presence of volatile organics with a photoionization detector (PID). Based on the soil screening, collection and analysis of soil samples for laboratory analysis will be completed. Soil classification will also be performed in the field in accordance with ASTM Method D2488, Standard Practice for Description and Identification of Soils. A boring log will be created for each soil boring showing stratigraphic sequence and associated field screening notes and observations. Visual evidence of contamination will be noted on the Field Geologist’s log. We anticipate one soil sample will be collected in the debris layer from each boring and analyzed for VOCs, 8 RCRA metals, PAHs, pesticides, GRO, and DRO Silica Gel Method. In addition, a total of three soil samples will be collected below the debris layer in three separate borings and analyzed for the same analytical parameters. Soil samples will be collected in new glassware, placed in a cooler with ice, and submitted under chain-of- custody to Eurofins TestAmerica Laboratories, Inc. in Cedar Falls, IA for laboratory analysis. Soil boring locations were selected based on the locations of the proposed infrastructure within the Site boundaries as noted below: 190th Street Cul-de-sac at the end of Iteri Avenue City trail on the east end of the site Figure 4 shows the proposed soil boring locations on the preliminary plat dated January 3, 2020. 4.4 GROUNDWATER INVESTIGATION Groundwater samples will be collected from four (4) of the eight (8) soil borings described above. Groundwater is anticipated to be approximately 8 to 10 feet below grade. Upon reaching the shallow groundwater table, the subcontracted driller will construct a temporary well approximately 5 feet into the shallow groundwater table. The temporary well will be constructed using a 1-inch PVC riser with a 5-foot slotted PVC screen. Groundwater samples will be collected from the well using a check ball connected to dedicated polyethylene February 2020 4-3 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx tubing. Groundwater will be purged to the degree possible, allowing the temporary well to recharge. The samples will be collected in dedicated glassware, placed in a cooler with ice, and submitted under chain-of-custody to Eurofins TestAmerica Laboratory, Inc. in Cedar Falls, IA for laboratory analysis. Groundwater samples will be analyzed for VOCs, GRO, DRO with Silica Gel Method, dissolved 8 RCRA metals, pesticides and PAHs using methods outlined in Section 4.2. Proposed temporary well locations are shown on Figure 4. 4.5 SOIL VAPOR INVESTIGATION To evaluate the potential for vapor intrusion at the Site, soil vapor sampling is proposed. We propose three (3) soil vapor borings to be located along the south property boundary and three (3) soil vapor borings to be located within the proposed 190th Street. The soil vapor probe locations are shown on Figure 4. The soil vapor probes on the south side of the Site will assess potential vapor risk to the adjoining homes and may be conducted prior to approval of this Work Plan. We anticipate the soil probes will be drilled to a depth of 10 feet on the south side of the site and to a depth of 5 feet within proposed 190th Street. The probes will be drilled through the debris layer and the rod will be pulled back one foot to create a void space for sampling. The top of the hole around the rod will be grouted to seal the sample space from the above- ground atmosphere. Dedicated polyethylene tubing will then be placed down the rod and connected to a fitting at the rod tip. Three volumes of air will be purged out of the sample line with a syringe prior to collecting the sample. The samples will be collected in 1-liter Summa canisters equipped with a 200 milliliter per minute fill regulator and dedicated in-line moisture filter. The Summa canisters will be analyzed for VOCs and methane. The Summa canisters will be submitted under chain-of- custody control to Eurofins TestAmerica Laboratory, Inc. in Burlington, VA. A PID equipped with a 10.6 eV lamp and a 4-gas meter will then be connected to the tubing for field screening purposes upon the completion of sample collection. 4.6 QUALITY CONTROL QC procedures are of prime importance to this investigation to ensure quality of the data collected, and thus the interpretations made from this data. The Wenck corporate QC program will be followed throughout the investigation, which mandates the use of industry- wide accepted procedures and practices during investigations. Laboratory results will be reviewed with respect to the laboratory’s reported QC results, including assessment of whether any observed deviations from QC criteria will affect the usability of the data for the intended purpose. Results for any field QC samples (e.g., field duplicates, field blanks, etc.) will also be assessed, if collected. Matrix spike (MS) and matrix spike duplicate (MSD) samples will be collected for each sampling method at a rate of 1:20 samples collected for laboratory analysis. Rinsate blank samples will also be collected at a rate of 1:20. Lab provided methanol blanks will accompany each sample cooler. 4.6.1 Chain-of-Custody Records Field personnel are responsible for sample custody from the time of collection until the time of sample shipment. Samples must be kept in the secure possession of the sampler, meaning that they are either within sight of the sampler, in the sampler’s secure vehicle, or February 2020 4-4 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx within the secure office of the sampling firm. The CoC procedures implemented for the project will provide documentation of the handling of each sample from the time of collection until completion of laboratory analysis. The CoC form serves as a legal record of possession of the sample. A sample is considered to be "in custody" if one or more of the following criteria is met: The sample is in the sampler's possession. The sample is in the sampler's view after being in possession. The sample was in the sampler's possession and then was placed into a locked area to prevent tampering. The sample is in a designated secure area. Custody will be documented throughout the project field sampling activities by the CoC form initiated for each day during which samples are collected. This record will accompany the samples from the site to the laboratory and will be returned to the Wenck PM with the final analytical report. All personnel with sample custody responsibilities will be required to sign, date, and note the time on the CoC form when relinquishing samples from their immediate custody (except in the case where samples are placed into designated secure areas for temporary storage prior to shipment). Bills of lading or air-bills will be used as custody documentation during times when the samples are being shipped from the site to the laboratory, and they will be retained as part of the permanent sample custody documentation. CoC forms will be used to document the integrity of all samples collected. To maintain a record of sample collection, transfer between personnel, shipment, and receipt by the laboratory, CoC forms will be filled out for sample sets as determined appropriate during the course of fieldwork. February 2020 5-1 N:\Technical\8410 The Preserve\03 Investigation Work Plan\The Preserve_Investigation Work Plan FEB 2020.docx 5.0 Investigation Report Upon completion of the investigation and receipt of all analytical data, an investigation report will be prepared for submission to the MPCA.

Hosfield - Wenck Associates, Inc. Copy: Mr. David Knight – MPCA Brownfields Program Mr. Ryan Lundgren – MPCA Brownfields Program Date: March 6, 2020 Subject: Preliminary Soil Vapor Investigation – The Preserve, 19030 Kenwood Trail, Lakeville, MN MPCA Site ID: BF0001384 Wenck Associates Inc. (Wenck) was authorized by Mr. Steve Sauber of Progressive, LLC to complete soil vapor sampling activities at the proposed development known as The Preserve. The Preserve is located at 19030 Kenwood Trail in Lakeville, Minnesota (the Site) and is a total of 82-acres in size. Our project site consists of 6.8-acres of the 82-acre development located north of Kenwood Trail and east of the residence located at the above- mentioned address. The Site location is depicted in Figure 1. A Site Detail Map is included as Figure 2. In the interest of time, Progressive, LLC expedited one round of soil vapor sampling at the Site. Specifically, the sampling was conducted between the known dump area and the residential homes to the south along Iteri Avenue to identify if a soil vapor risk pathway is present. An Investigation Work Plan (Work Plan) for this work has been prepared and submitted to the Minnesota Pollution Control Agency (MPCA) for review and is pending approval. The Work Plan dated February 20, 2020 was followed during this investigation. Soil Vapor Investigation Wenck completed the soil vapor investigation on February 25, 2020. The investigation included advancing three soil vapor probes at locations SV-1, SV-2 and SV-3. The locations are shown on Figure 3. Access to the drilling area was from the existing driveway to the west. The proposed sampling locations were initially located just north of the south property boundary and south of the delineated wetland lines. Based on the steep topography and heavy tree coverage in the area, the probe locations were moved north of the wetland delineation line, closer to the dump. Geoprobe Post-Run Tubing (PRT), vapor sample specific tooling, was advanced to a depth of 10 feet below ground surface (bgs) and the rod was pulled back two feet to create a void space for sampling (i.e., 8-10 feet bgs). The top of the hole around the rod was grouted to seal the sample space from the above ground atmosphere. Dedicated polyethylene tubing was placed down the rod and connected to a fitting at the rod tip. Approximately 300 milliliters (mL) of air was purged from the sample line with a syringe prior to collecting the sample. The samples were collected in 1-L Summa canisters equipped with 200 mL per minute flow restrictors and dedicated in-line moisture filters. The soil vapor samples were submitted under chain-of-custody control to TestAmerica for analysis of VOCs using EPA EXHIBIT R Steve Sauber Progressive, LLC March 6, 2020 2 N:\Technical\8410 The Preserve\04 Vapor Sampling\MPCA BF1384_The Preserve_Soil Vapor Report 030520.docx Method TO-15 and methane using EPA Method 3C. A photoionization detector (PID) equipped with a 10.6 eV source lamp and a multi-gas meter the lower explosive limit (LEL) and hydrogen sulfide were connected to the tubing for field screening purposes upon the completion of the Summa can sample collection. A soil vapor sampling form is included as Attachment A. Soil vapor probe SV-1 was drilled to 10 feet below grade (bg) and set to create a sampling space between 8 to 10 feet bg. Soil vapor probe SV-2 encountered water during sampling, so the boring was re-drilled and sampling was conducted between 4 to 6 feet bg. Soil vapor probe SV-3 encountered heavy debris and refusal several times before the final depth of 10 feet was achieved. Sample SV-3 was collected from 8 to 10 feet bg. Soil vapor data was compared to MPCA Residential ISVs. The guidelines were initially developed by the MPCA in 2010 and serve as the state’s regulatory screening values for vapor intrusion risk in varying settings. The MPCA updated the ISV values in May 2019 to reflect the U.S. Environmental Protection Agency’s (EPA) risk assessment methodology established in 2018 and default parameters for the highest likely exposure issued in 2014. Expedited ISVs (EISVs) are also used to help determine the need for expedited action based on the protection of human health. Residential ISVs and EISVs are divided by 0.03 (i.e. multiplied by 33, or 33X) to evaluate vapor intrusion potential as an “attenuation factor” to represent the presumed minimum decrease in concentration from the subsurface to the breathing zone. Various VOCs were detected at concentrations above their respective laboratory reporting limits in all three soil vapor samples. However, none of the detections exceeded their respective 33X the MPCA Residential ISVs with the exception of 1,3-butadiene, which was detected above 33X the Residential ISV in samples SV-1 and SV-2. 1,3-Butadiene is primarily used in the manufacture of synthetic rubber, it forms during combustion and may be a product of microbial degradation occurring in soil. It is found in wood and cigarette smoke, oil burner emissions, rubber tires and exhaust from internal combustion engines. Based on widespread sources, some of which are anthropogenic and others possibly naturally occurring, the detections of 1,3-butadiene do not appear related to a release at the Site. Soil vapor sample results are summarized results on Table 1. The laboratory report and supporting chain-of-custody documentation are included as Attachment B. In addition, there were no elevated PID readings recorded at the three soil vapor sampling locations. There were also no concentrations of hydrogen sulfide or LEL recorded above 0.0 with the multi-gas meter. The PID and multi-gas meter results are recorded on Table 1. Conclusions and Recommendations Based on the laboratory analysis of the soil vapor samples collected as a part of this soil vapor investigation, Wenck submits the following conclusions and recommendations: Low concentrations of VOCs were identified in all three soil vapor samples collected from the Site. None of the detected concentrations exceeded their respective 33X MPCA Residential ISVs with the exception of 1,3-butadiene. Due to the widespread origins of 1,3-butadiene, it is assumed that its presence in the soil vapor samples do not indicate a release of hazardous substances to the Site.

(Wenck) has prepared this addendum for the previously submitted Investigation Work Plan for The Preserve located at 19030 Kenwood Trail in Lakeville, MN (the Site). The Investigation Work Plan was submitted to the Minnesota Pollution Control Agency (MPCA) on February 20, 2020. After preliminary review of the Investigation Work Plan, an addendum was requested by MPCA Project Managers, Mr. David Knight and Mr. Ryan Lundgren. This addendum will address the following: Expand the Site boundaries to include two surficial dump areas identified in the 2019 Phase I ESA prepared by Haugo GeoTechnical Services, LLC. The surficial dumps are identified on the existing conditions survey (Figure 3). Extend the Site boundaries to include the former homestead at 19030 Kenwood Trail. Define the extent of the surficial dumps in the field and document. Conduct additional soil, groundwater and/or soil vapor testing as necessary. Based on the newly defined Site boundaries, the Site is approximately 396,500 square feet or 11.4 acres. The site is 500 feet by 978 feet as shown on Figures 3 through 5. This addendum includes additional sampling in addition to what is outlined in the February 2020 Investigation Work Plan: Conduct test pits around each surficial dump as indicated on Figure 3 to define the extents. The test pits will help to define these areas for future removal of surficial debris and/or impacted soils in future development areas (i.e., roadways, trails, greenspace and/or building pads). Test pit locations are plotted on Figure 3. Collect one soil sample from each surficial dump area for analysis of the parameters listed in Section 4.2 of the Investigation Work Plan. Conduct additional soil, groundwater and soil vapor sampling via soil borings in the northeast corner of the Site. Additional sets of samples will be collected in the area of the proposed building pad #9 and within 190th Street near the east side of the Site. The additional boring locations are plotted on Figure 5.

The Planning Commission conducted a public hearing on the proposed variance preceded by published and maile d notice. The applicant was present and the Planning Commission heard testimony from all interested persons wishing to speak. The Planning Commission hereby recommends the following: FINDINGS OF FACT 1. The property is located in Planning District No. 4 of the Comprehensive Plan which guides the property for low density residential land uses. 2. The property is zoned RS-2, Single Family Residential District but is proposed to be rezoned to RS-3, Single Family Residential District . 3. The legal description of the property is: (See Attached Exhibit A) 4. Section 11-6-5 of the Zoning Ordinance requires that certain criteria be met in consideration of a variance request. The criteria and our findings regarding them are: a. That the variance would be consistent with the comprehensive plan. Finding: The variance is consistent with the low-density land use designation of the 2040 Comprehensive Plan. b. That the variance would be in harmony with the general purpose and intent of the Zoning Ordinance. 2 Finding: The variance for reduced buffer yard lot width will be in harmony with the general purpose and intent of the Zoning Ordinance with the increased buffer yard landscape screening adjacent to 190th Street. c. That the plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The unique circumstances are the physical and natural environment characteristics of the property. The variance for lot width for the three lots would result in minimizing impact to trees and wetlands within the property. d. That the purpose of the variance is not exclusively for economic considerations. Finding: The purpose of the variance is to balance a maximization of the developable space on the property with protection of the natural environment. e. That the granting of the variance will not alter the essential character of the neighborhood in which the parcel of land is located. Finding: The three lots subject to the variance will meet minimum lot size and building setback requirements of the Zoning Ordinance. f. That the requested variance is the minimum action required to eliminate the practical difficulty. Finding: The proposed variance is the minimum necessary to allow homes to be constructed on the affected lots while meeting setback requirements. g. Variances may not be approved for any use that is not allowed under this section for property in the zone where the affected person’s land is located.

The property is bisected by two drainageways draining from the north t o the southeast and southwest. An existing building (homestead) and accessory buildings were located on one of the parent parcels, and were demolished in 2019. During the building demolition, various su rficial dump sites were discovered on the property. The Developer hired Wenck Associates, Inc. to prepare an investigation work plan on the property to evaluate the site conditions and determine its feasibility for development. The work plan included soil, groundwater and soil vapor sampling activit ies within the site after the discovery of the buried debris. The deepest depth of debris extended to approximately 11 feet below grade. A summary of the current environmental information and proposed environmental activities has been submitted to the City. Based on the results of the study, a Response Action Plan (RAP) will be prepared and submitted to the MPCA for review and approval. The development improvements must be completed in accordance with the recommendations identified in the RAP.
