RIGHT.OF-WAY AND EASEMENTS There is an existing 2O-foot wide Metropolitan Council Environmental Services (MCES) sewer and utility easement located on the property as illustrated on the submitted plans. Generally, the easement traverses from the northwest comer ofthe property to the southeast comer of the property, bisecting the site diagonally. The applicant is proposing to impact the easement at two locations. The first location is within the northwest comer of the site where grading and construction of "Mauie Circle" and Basin 200 are proposed. The second location is to the east of "Visionary Court" where grading is proposed behind Lots 119-120. The MCES has been supplied the applicant's site plans and all comments and conditions set forth by the MCES shall be addressed by the applicant. An agreement to construct any of the proposed improvements over the MCES'S easement must be executed and supplied to the city for review prior to the issuance of grading permits. As grading and construction is proposed in these easements for The Park 2'd Addition, an agreement will be required. The applicant is proposing standard drainage and utility easements (D&U's) around the majority of the lots on the provided preliminary plat. Additional 20-foot wide D&U's have been provided within Lots 139-153 abutting "Mattie Circle" and Lots 166-169 abufting Topaz Drive. These 20- foot wide D&U's are provided for stormwater collection and conveyance systems located in backyards that fall outside the standard D&U's. Furthermore, 30-foot wide D&U's between Lots 20-21 abutting "Fathers Song" and Lots 5-6 abutting "Paisley Path" have been proposed to provide access to proposed utilities and the north and south side of Basin 300. Thirty-foot (30-foot) wide D&U's between Lots 151-152 abutting "Mattie Circle" have been proposed to provide access to a water main extension to Ruby Lane. fught-of-way dedication will be required along the east side of Galpin Boulevard per Carver County's review and comments (see "Camer County Development / Access Review Comments" attached), the Highway 117 Corridor Study, and the typical roadway sections identified in the county's Draft 2040 Comprehensive Plan. The Corridor Study identifies specific right-of-way needs and the plat will be required to follow and be consistent with the preferred roadway altemative. The right-of-way shall tie into the existing highway right-of-way north and south of the proposed development. The final plat proposal shall be reviewed and approved as to form and content by the county surveyor and city. After review by the city of the proposed final plat for The Park, adequate right-of-way has been dedicated. Todd Gerhardt The Park 2nd Addition Final Plat Jamary 27,2020 Page22 The applicant will be required to underground all overhead utilities within the development. Underground utilities reduce the risk ofaccidents, such as vehicles colliding with poles and service impacts such as storms knocking down limbs on lines. It also improves the overall esthetics of roadway corridors and neighborhoods, which improves and promotes livability. Lastly, as experienced during the construction ofThe Park (1't Addition), Galpin Boulevard was frequently utilized as a staging area for construction traflic. This method of staging on a collector road causes ahazard to motorists utilizing the corridor, especially as Galpin Boulevard adjacent to the development has poor sight lines. In an effort to mitigate this occurrence during the 2nd Addition construction, the developer and their contractors shall submit a plan to ensure that no construction traffic stages on Galpin Boulevard or obstructs any travel lanes. EXISTING CONDITIONS SURVEY Water wells and septic fields have been identified on the existing conditions survey. The abandonment of all existing wells shall be in accordance with the Minnesota Department of Health's review and regulations, and the abandonment ofall existing septic systems shall be in accordance with the Minnesota Pollution Control Agency's review and regulations. All required permits fiom the appropriate regulatory agencies shall be obtained prior to the commencement ofany abandonment(s). GRADING The applicant is proposing to construct eight stormwater basins (Basins 100, 200, 300, 400, 500, 600, 800, 900) within and around the development. Through the preliminary grading plan and grading details, drainage from individual lots will be routed away from buildings into a series of catch basins and HDPE pipe located within drainage and utility easements in backyards. Drainage from proposed public streets will be collected through catch basins located next to curbs, and routed to stormwater basins within and around the site. The applicant has provided an overall grading plan and the phased grading schedule for the entire subdivision as well as a grading plan for The Park 2nd Addition. Both plans generally conform to city ordinances and standards for grading, with minor changes required. The applicant shall meet all the conditions enumerated with the development contract prior to commencement of grading operations. There are proposed driveways that approach the maximum 10% grade (e.g. Lot 152 abuuing "Mattie Circle" is at 9.9%o grade) and one street that reaches the maximum 7% grade ("Purple Parkway" near station l+45) allowed by city ordinance. Staff recommends limiting maximum grades in order to achieve a higher level of constructability. Any constructed street or driveway that exceeds maximum allowable grades upon final inspection will be required to be removed and replaced. There are two bluffs within the site. One bluffis located west of Lots 106-164 abuuing Lucy Ridge Lane, and a second bluff is located south ofLots 148-149 abutting "Mattie Circle". The grading plans indicate the locations and extent of the bluffs and their appropriate buffers and setbacks. All grading operations have been proposed to be outside the bluff impact zones. Todd Gerhardt The Park 2nd Addition Final Plat IanuNy 27 ,2020 Page2l Currently, while the grading plan shows a majority of stormwater being routed to appropriate treatment methods (BMPs), some lots (e.g. Lots l0- 13 abutting "Visionary Court") do not appear to have a method of conveying untreated stormwater runoff to BMPs. As by city ordinances, no untreated stormwater shall be routed to wetlands prior to treatment. While the proposed public trail system meets the Americans with Disabilities Act Accessibility Guidelines (ADAAG) for maximum running slope of trail segments (no more than 30% of the total trail lengh to exceed a I : 12 slope), staffrecommends the installation of a level resting pad over continuous glades over 8%. This recommendation is based on the intent of the ADAAG which is to provide access to the greatest extent possible. The plat's final grading plans, ponds, and right-of-way along Galpin Boulevard shall be reviewed and approved by the county and the city to show how they conform to the potential future Galpin Boulevard reconstruction. A cross reference of grading plans, profiles, and respective cross sections should be provided at key locations such as intersections, ponds, or other special features for review by the county and city prior to acceptance. SHORELAND MANAGEMENT This phase is not in the shoreland management area. RETAINING WALLS No retaining walls are being proposed with the development. STREETS The applicant is proposing construction of nine new streets (Mattie Circle, Pearl Drive, Visionary Court, Fathers Song, Alphabet Street, Purple Parkway, Paisley Path, Paisley Court, and Rogers Court) and the extension ofone existing street (Lucy Ridge Lane) that shall be owned and maintained by the city after acceptance of the public improvements by the City Council. All newly constructed street sections shall be designed to meet the current standard specifications and detail plates for residential streets. These new streets and extensions will result in eight cul-de-sacs with seven of the eight proposed cul-de-sacs meeting current city code and standard specifications. "Mattie Circle", a newly constructed street and cul-de-sac in the northem section ofthe development, exceeds the maximum lenglh for a cul-de-sac per city ordinance; however, it was approved in the preliminary plat by City Council. Engineering recommended approval ofthe cul-de- sac as the topography would require substantial grading and the loss of significant trees that would alter the physical character of the property and surrounding parcels (Ordinance I 8.57.k.2). Access to "Mattie Circle" is from Galpin Boulevard, a collector road. There is an existing driveway 30 feet south of "Mattie Circle" providing access to Parcel 250100400. This spacing does not meet MnDOT Access Management Guidelines or Carver County's requirements for access points off of collector roads. The parcel's access from Galpin Boulevard will be abandoned and realigned to tie Todd Gerhardt The Park 2'd Addition Final Plat lmuary27,2020 Page 24 The applicant has supplied a geotechnical evaluation report that was completed by Braun Intertec Corporation on June 29,2018. The report discussed and explored design and construction recommendations for roadway sections, amongst other topics. The updated plans and updated geotechnical evaluations provided since the original preliminary plat submittal show adequate boring information and provide sufficient guidance on the construction ofthe public streets. However, it will be required ofthe developer to have a geotechnical engineer onsite during grading operations. If groundwater is encountered during grading, grades shall b€ adjusted to maintain a 3-foot separation from the bottom floor elevation of proposed buildings. Subsequent changes to grades shall be submitted to the city for review and approval. Sidewalks and pedestrian access points have been proposed on a majority of the streets throughout the development. However, Lucy Ridge Lane will require an extension of sidewalk to provide access within the cul-de-sac. Sidewalks shall be constructed in accordance with city standard specifications and detail plates. All curb ramps shall be constructed to meet ADA standards and the city's detail plates. The sidewalk located at the intersection of Galpin Boulevard and "Pearl Drive" terminates with no proposed intersection improvements to access the existing trail system on the west side. The developer will be required to extend connectivity by providing access from the newly constructed east side to the existing west side of Galpin Boulevard by utilizing approved MUTCD practices for pedestrian crosswalk and intersection improvements. Street lights have been proposed throughout the development. Street lights will be required at all intersections and at the end ofeach cul-de-sac. The developer will need to work with Xcel Energy on the installation of city-approved street lights. A $300 fee shall be collected with the development contract for each street light for the purpose ofelectricity costs for the first year ofoperation. WATER The applicant is proposing to construct 8" PVC C900 water main throughout the development that shall be owned and maintained by the city after acceptance ofthe public improvements by the City Council. The development is located between two pressue zones in the city; a high pressure zone and a low pressure zone. To the west, in the Longacres neighborhood, is a high pressure zone. To the north and south, in the Ashling Meadows and Royal Oak Estates neighborhoods, respectively, are low pressure zones. The city has modeled the impact of the development based on the proposed usage. It was found that in order to provide adequate pressures and fire flows, water mains shall be tied into the high pressure zone located on Galpin Boulevard. This will result in some areas ofthe development experiencing pressures above 90 PSI. Therefore, a portion of the homes will likely require individual pressure reducing valves. The developer will need to work with the Building into "Mattie Circle" as the future Galpin Boulevard Redevelopment project approaches. Additionally, a water stub for future connection shall be installed to serve the property. The city has had discussions with the resident ofthis property and has obtained verbal agreeance ofsuch a realignment and future water service connection. Todd Gerhardt The Park 2nd Addition Final Plat Jaruary27,2020 Page25 Department and Public Works Utility Department to determine which homes will require pressure- reducing valves. In the northwest area ofthe development where Lucy Ridge Lane will be extended, the developer is proposing to tie into the low-pressure water system via the existing 8" PVC water mains. Engineering does not anticipate any extraordinary impacts to the water system's pressure or fire flow for the proposed 15 connections. "Mattie Circle" will be tied into the high zone water system via the existing water main off Galpin Boulevard. "Mattie Circle" is an approved cul-de-sac by way of acceptance of the preliminary plat, and the applicant was proposing the creation of a dead end system. The Public Works Utility Departrnent required the applicant to tie in the proposed water main on "Mauie Circle" to the existing water main srub located offRuby Lane, to the north, which is now being proposed with the updated preliminary plans. Because "Mattie Circle" will be within the high-pressure zone, and the north tie-in location on Ruby Lane (Ashling Meadows neighborhood) is within the low-pressure zone, updated construction plans call out a gate valve to be installed where the system ties in. This gate valve will remain closed in order to separate the two zones, and will be opened by city forces during any maintenance or repair work in order to "back feed" the system, as necessary. The majority ofthe water main to be installed is within the central and southem portion ofthe development (The Park ls,2nd and 3'd Additions). The applicant is proposing to create a looped water system that meets the city's best management practices for water utilities. Looped systems improve reliability by feeding water from two directions rather than one, which subsequently allows service to continue during an event that may otherwise cause disruption to water service. Water main connections will be tied into the high zone water system offGalpin Boulevard. The applicant shall verifu the location of the connections on the construction plans. All water main taps, connections, and required water main testing shall be witnessed by the city. A pre-construction meeting prior to the commencement ofany work shall be scheduled by the developer's contractor with the city. Additionally, all underground utilities on the east side of Galpin Boulevard have no1 been located and illustrated on the plans, for example, the city's raw water main that feeds the west treatment plant. This area on the east side of Galpin Boulevard is where water will cross before entering the development. Thus, prior to the issuance of public utility construction, all underground utilities in this area (east and west of Galpin Boulevard) shall be surveyed and illustrated in the profile sheets in order to identifu any conflicts. From the proposed preliminary water plans, there are multiple areas where water main and sanitary sewer mains will cross. All crossings of water and sewer utility mains are required to have 18" of vertical separation and l0' of horizontal separation, measured from the edge of pipe. Where water mains cross sanitary sewer mains and do not meet vertical or horizontal separation requirements, the sanitary sewer shall be constnrcted of C900 water main material. All crossings shall be required that the sanitary sewer pipe length shall be centered over the water main crossing. The preliminary plans delineate areas where water main will run closely adjacent to, or under, storrnwater catch basins. This may cause a potential for freezing of the water main at these locations Todd Gerhardt The Park 2nd Addition Final Plat JaruNy27,2020 Page26 due to inadequate ground cover from catch basin bottoms (sumps) to the water main. Water mains shall be constructed at7.5' below grade, or be insulated, and constructed in conformance with the city's standard specifications and detail plates. Plan and prohle sheets provided with the construction drawings ofthe water main shall include the location and depth ofcatch basins and their sumps for review and approval prior to issuance ofa notice to proceed. The applicant shall ensure all hre hydrant spacing meets fire codes and are subject to the review and approval of the Fire Department. SANITARY SEWER The applicant is proposing to construct 8" PVC sanitary sewer main throughout the development that shall be owned and maintained by the city after acceptance ofthe public improvements by the City Council. The entire sanitary sewer system will operate as a gravity system and connects to existing sanitary sewer mains at three locations; Lucy Ridge Lane, a direct connection to the MCES sanitary sewer trunk line on "Mattie Circle", and at the Majestic Way extension offof "Paisley Path". As proposed, the connection to the MCES sanitary sewer trunk line from "Mattie Circle" and its subsequent manhole are not within the roadway, down steep grades, and abutting Basin 200. The applicant shall resubmit construction drawings with this phase ofthe development to provide the access manhole and tie-in on and within "Mattie Circle". All conditions set forth by MCES shall be addressed by the applicant for the required access manhole and direct connection to their trunk line, and all permits required shall be obtained prior to the commencement of construction. The pteliminary plans submitted utilize a nomenclature for identifuing proposed manholes that aligns with the city's. The city provided a list of appropriate manhole identifiers, as well as fire hydrant identifiers. This will ensure an effrcient transition ofthe newly constructed public improvements into the city's asset management system for sanitary sewer manholes and fire hydrants. The applicant shall ensure the city's manhole naming conventions supplied are incorporated within the plans and on all future submittals. Profile sheets for all public utilities, including sanitary sewer, shall be required for review and approval by the city prior to issuance of building permits for all phases. Based on the provided profile and plan sheets for The Park 2nd Addition, the applicant is proposing sanitary sewer that reaches a maximum depth requiring PVC class C900. PVC sanitary sewer pipes that have a burial depth of 0-16 feet are required to be class SDR 35, burial depths of 16-26 feet requires class SDR 26, and burial depths of greater than 26 feet requires class C900. The applicant has shown that the proposed sanitary sewer pipes falling within these burial depths have the appropriate class ofPVC. STORMWATER MANAGEMENT Todd Gerhardt The Park 2nd Addition Final Plat laruary 27,2020 Page27 1. The applicant has delineated all wetlands on the property and agencies have approved the boundaries and type. 2. Wetland permitting is required due to the proximity and proposed impacts to wetlands onsite. Grading permits could be issued as all approved wetland permits have been received. See "Iletland Alteration" of this staff report for more information. 3. An NPDES permit has been obtained by the applicant. An updated stormwater pollution and erosion control plan shall be provided. 4. An opetations and maintenance plan for the proposed stormwater management systems have been entered into with the Riley Purgatory Bluff Creek Watershed District (RPBCWD) and the applicant. Preliminarv Plans Infiltration test results will be required in the location ofall proposed infiltration benches and infiltration basins. Infiltration test results have not been submitted in the location of proposed Basin 100. If filtration is to be used, the applicant will need to provide a specification for amended soils. WETLAND ALTERATION The plan set shows intent to impact several wetlands on site. A Wetland Replacement Plan application was submitted to the city and reviewed per the WCA. A Notice of Decision and Approval for the Wetland Replacement Plan was sent on June 6, 2019. Wetland mitigation was approved through the purchase of wetland credits with wetlands being replaced at a ratio of2: L Wetland 14, proposed to be impacted during The Park ('l't Addition"), required a United States Army Corps of Engineering (USACE) permit as it was determined to be a USACE jurisdictional wetland. The approved permit was submitted to the city. Wetland buffers using buffer averaging has been applied to the project. Wetland buffers and buffer setbacks pursuant to section 20-41 1 and consistent with the preliminary plat must be memorialized with a recorded wetland buffer agreement filed with the county recorder's ofnce. EROSION PREVENTION AND SEDIMENT CONTROL The proposed development will exceed one (l) acre ofdisturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activiry Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). The applicant has prepared and submitted a Surface Water Pollution Prevention Plan General 5. All comments and conditions set forth by the RPBCWD shall be addressed by the applicant. Todd Gerhardt The Park 2nd Addition Final Plat Jawary27,2020 Page 28 (SWPPP) to the city and has obtained an NPDES Construclion Permit for The Park. An updated erosion and sediment control plan meeting the requirements of City Ordinance Sec. 19-145 shall be submitted for review and approval prior to the commencement ofany grading operations. Financial A ssurance To guarantee compliance with the grading plan, and related remedial work, a cash escrow or letter of credit, satisfactory to the city, shall be fumished to the city before a Notice to Proceed is issued for The Park 2nd Addition. The escrow amount shall be $3,148,71l 83, which is I10% of the estimated costs of construction for The Park 2nd Addition. The city may use the escrow or draw upon the letter ofcredit to reimburse the city for any labor or material cosls it incurs in securing compliance with the plan or in implementing the plan. The city shall endeavor to give notice to the owner or developer before proceeding, but such notice shall not be required in an emergency as determined by the city. The assurance shall be maintained until final stabilization and removal oferosion and sediment controls and acceptance ofdedicated public streets and public utilities. STORMWATER UTILITY CONNECTION CHARGES Section 4-30 of City Code sets out the fees associated with surface water management. A water quality and water quantity fee are collected with a subdivision.

The Utility & Street Construction Plans (“U&SC Plans”) sheet numbers must be updated to reflect the proper sequencing of sheets for clarity, e.g. Sheet 1.1 of 28 does not have a Sheet 28 within the set. 42. On Sheet 1.1 of the U&SC Plans, provide a separate, enlarged inset detail of the proposed connection to the 14” HDPE water main at the intersection of Galpin Boulevard and Longacres Drive/“Pearl Drive” that includes plan and profile views of the location of all existing utilities. The updated plan is required prior to the commencement of any construction activities in this location, pending review by the City. The newly installed 8” C900 watermain shall be installed with a casing pipe with no bends, any conflicting utilities shall be lowered. 43. On Sheet 1.1 of the U&SC Plans, an air release valve and manhole shall be located near the high point of the watermain, pending revisions from condition 42 (above); construction note 208738v2 SP-8 5. shall indicate “1” I.P.S. PE”; the gate valve located near station 5+15 along “Pearl Drive” over the sanitary main shall be offset 5’to the east; the irrigation service stubbed near station 0+95 along “Pearl Drive” must be PE and not DIP and shall be 1”, if a larger diameter service line is required a justification must be submitted to the City for review; all watermain within 7.5’ of catch basins shall be insulated, e.g. at stations 1+60 and 4+75 along “Pearl Drive”; all hydrants shall be located 10’ away from light poles, e.g. at the intersection of “Pearl Drive” and “Purple Parkway”; on the profile the future watermain shall be called out as such and the plug should be illustrated for clarity. 44. On Sheet 1.2 of the U&SC Plans, lower watermain to avoid the conflicts with storm sewer catch basins and to minimize the required drops/bends/fittings, up to a maximum of 10’ below grade watermain will be accepted, pending review and approval; all sanitary sewer shall have a minimum slope of 0.50%, e.g. pipe runs between MH 16-085 to 16-094 maintain 0.40%; where “see watermain offset detail” is called out on plans indicate the page number for clarity. 45. On Sheet 1.3 of the U&SC Plans, MH 16-084 shall be lowered to maintain a 4% grade between MH 16-084 and MH 16-083; watermain shall be lowered to avoid conflicts and to maintain a consistent grade past station 4+00; water and sanitary services to Lot 6 of Block 4 and Lot 9 of Block 3 shall be adjusted away from catch basins and be insulated if necessary; a gate valve shall be installed near the connection to the existing C900 off “Purple Parkway” near station 9+75; the note calling out “connection to existing 8” DIP” shall be adjusted to 8” C900, for clarity. 46.

On Sheet 1.5 of the U&SC Plans, the submitted temporary traffic control plan indicates the use of MnDOT Traffic Control Layout 6K-17, however the provided proposal does not adhere to this standard and must be adjusted accordingly, e.g. the required buffer space is well below the standard; where CL-5 aggregate is called a note is to be added identifying that the aggregate shall be rolled and compacted prior to opening the bypass; note 3 shall clearly state this work is to be conducted by the Developer’s contractor and/or their subcontractor(s); the scale provided should be updated to a typical engineering scale; review and approval of the temporary traffic control plan by the County shall be provided to the City prior to any work on County Road 117. 48. On Sheet 1.6 of the U&SC Plans, add “Road Work Ahead” sign 600 feet before the “One Lane Road Ahead” signage; add additional “Flagger Ahead” sign south of Wynsong Lane. 49. On Sheet 2.1 of the U&SC Plans, “Storm Sewer Construction Notes” indicate usage of Neenah casting R-3067VB at catch basin low points, however the structure table does not indicate any “VB” structures, update accordingly; the formatting under “Storm Structure Table Notes” is not clear, it appears the notes are all related to water tight structures, if this is the case offsetting the sub-bullets (A-D) may make this clearer, update accordingly. 50. On Sheet 2.2 of the U&SC Plans, ensure all storm sewer conveyance pipe is entirely below road sections, e.g. between CBMH-426 and CBMH-425 the pipe would encroach into the road 208738v2 SP-9 section as the cover from top of pipe to proposed grade is 36”, adjust storm sewer accordingly; profile shall be updated to include stationing; FES-433 shall include trash guard; all catch basins throughout the plan set shall be located perpendicular to each other when on opposing sides of the road, e.g. CBMH-431 and CBMH-430 should be updated accordingly. 51. On Sheet 2.3 of the U&SC Plans, update plan view to show entire pipe run as CB-351 on plan view is not shown. 52. On Sheet 2.4 of the U&SC Plans, CBMH-336 and CBMH-335 should be relocated to achieve a perpendicular alignment per condition 50 (above), this may be accomplished by locating near station 1+20 to avoid conflict with Lot 1 of Block 2 driveway, furthermore this would allow for a recommended 2’x3’ catch basin rather than a catch basin manhole. 53. On Sheet 2.6 of the U&SC Plans, CBMH-303 shall have a 4 foot sump with SAFL baffle and the detail sheets shall be updated accordingly; update plans to indicate type of plug identified east of CBMH-306; remove trash guard from FES-300. 54. On Sheet 3.1 of the U&SC Plans, the pedestrian ramp type called out in the legend (MnDOT 7036F) is a 2004 detail plate and has been discontinued, update accordingly; maintain a 10’ separation from pedestrian ramps and catch basin castings at all times, e.g. in front of Lot 5 of Block 6; a sidewalk detail should be included as typical either on the plan sheets or within the detail sheets and called out accordingly; construction notes regarding street sign locations and installations should be included, coordination with Public Works is required; plans shall be updated to incorporate the pedestrian improvements at the intersection of Longacres Drive and Galpin Boulevard as conditioned upon approval of preliminary plat. 55. On Sheet 3.2 of the U&SC Plans, there is a call-out “???” over Lot 8 of Block 6, which must be removed or clarified. 56. On Sheet 3.4 of the U&SC Plans, the “eyebrow”, or half cul-de-sac bubble, between stationing 3+00 and 4+00 should be constructed so that the flow line for street drainage is to be maintained 15.5’ from centerline of “Alphabet Street”, this is required in order to minimize the amount of street drainage being routed around the eyebrow and creating a “bird bath” or drainage issues abutting Lot 20 of Block 4. Stormwater Conditions & Wetlands 1. All comments and conditions set forth by the Riley Purgatory Bluff Creek Watershed District shall be addressed by the Developer. 2. A defined riprap EOF spillway will be required for all stormwater basins. Developer should include location and elevation of all EOF spillways on the storm sewer plans. 3. Stormwater runoff shall not be discharged into wetlands without water quality pretreatment as prescribed by City Code. 208738v2 SP-10 4. Wetland Buffers. Wetland buffers and buffer monumentation will be required adjacent to the wetlands on site. Wetland buffer widths and locations where signage will be placed must be indicated on a plan sheet. Please find additional information on signage placement in the City’s guidance document. The WMO provides signs and sign posts for the cost of materials. Alternative signs (by the City or Developer) are also acceptable provided they contain similar information. Wetland buffers and buffer setbacks pursuant to section 20-411 and consistent with the preliminary plat must be memorialized with a recorded wetland buffer agreement filed with the county recorder’s office. 5. Where possible, the Developer shall update all storm sewer so the maximum pipe velocity is 12 feet per second. If not possible, pipe velocities should not exceed 15 feet per second per MnDOT guidance. Landscaping and Tree Preservation 1. Tree preservation fencing shall be installed around existing trees to be saved prior to any construction activities and remain installed until completion. 2. Any well house access road established by Developer shall avoid removals of any significant trees in Outlot E or F, Park Addition and shall require written approval by the City for access or work within City Property.

Right to Proceed. Within the plat or land to be platted, the Developer may not grade or otherwise disturb the earth, remove trees, construct sewer lines, water lines, streets, utilities, public or private improvements, or any buildings until all the following conditions have been satisfied: 1) this agreement has been fully executed by both parties and filed with the City Clerk, 2) the necessary security and fees have been received by the City, 3) the plat has been recorded with the County Recorder's Office or Registrar of Title’s Office of the County where the plat is located, and 4) the City Engineer has issued a letter that the foregoing conditions have been satisfied and then the Developer may proceed. 2. Phased Development. If the plat is a phase of a multiphased preliminary plat, the City may refuse to approve final plats of subsequent phases if the Developer has breached this Contract and the breach has not been remedied. Development of subsequent phases may not proceed until Development Contracts for such phases are approved by the City. Park charges and area charges for sewer and water referred to in this Contract are not being imposed on outlots, if any, in the plat that are designated in an approved preliminary plat for future subdivision into lots and blocks. Such charges will be calculated and imposed when the outlots are final platted into lots and blocks. 3. Preliminary Plat Status. If the plat is a phase of a multi-phased preliminary plat, the preliminary plat approval for all phases not final platted shall lapse and be void unless final platted into lots and blocks, not outlots, within two (2) years after preliminary plat approval. 4. Changes in Official Controls. For two (2) years from the date of this Contract, no amendments to the City's Comprehensive Plan, except an amendment placing the plat in the current urban service area, or official controls shall apply to or affect the use, development density, lot size, lot layout or dedications of the approved plat unless required by state or federal law or agreed to in writing by the City and the Developer. Thereafter, notwithstanding anything in this Contract to the contrary, to the full extent permitted by state law the City may require compliance with any amendments to the City's Comprehensive Plan, official controls, platting or dedication requirements enacted after the date of this Contract. 5. Improvements. The improvements specified in the Special Provisions of this Contract shall be installed in accordance with City standards, ordinances, and plans and specifications which have been prepared and signed by a competent registered professional engineer furnished to the City and approved by the City Engineer. The Developer shall obtain all necessary permits from the Metropolitan Council Environmental Services and other pertinent agencies before proceeding with construction. The City will, at the Developer's expense, have one or more construction inspectors 208738v2 GC-2 and a soil engineer inspect the work on a full or part-time basis. The Developer shall also provide a qualified inspector to perform site inspections on a daily basis. Inspector qualifications shall be submitted in writing to the City Engineer. The Developer shall instruct its project engineer/inspector to respond to questions from the City Inspector(s) and to make periodic site visits to satisfy that the construction is being performed to an acceptable level of quality in accordance with the engineer's design. The Developer or his engineer shall schedule a preconstruction meeting at a mutually agreeable time at the City Council chambers with all parties concerned, including the City staff, to review the program for the construction work. 6. Iron Monuments. Before the security for the completion of utilities is released, all monuments must be correctly placed in the ground in accordance with Minn. Stat. § 505.02, Subd. 1. The Developer's surveyor shall submit a written notice to the City certifying that the monuments have been installed. 7. License. The Developer hereby grants the City, its agents, employees, officers and contractors a license to enter the plat to perform all work and inspections deemed appropriate by the City in conjunction with plat development. 8. Site Erosion and Sediment Control. Before the site is rough graded, and before any utility construction is commenced or building permits are issued, the erosion and sediment control plan, Plan B, shall be implemented, inspected, and approved by the City. The City may impose additional erosion and sediment control requirements if they would be beneficial. All areas disturbed by the excavation and backfilling operations shall be reseeded forthwith after the completion of the work in that area. Except as otherwise provided in the erosion and sediment control plan, seed shall be certified seed to provide a temporary ground cover as rapidly as possible. All seeded areas shall be fertilized, mulched, and disc anchored as necessary for seed retention. The parties recognize that time is of the essence in controlling erosion and sediment transport. If the Developer does not comply with the erosion and sediment control plan and schedule of supplementary instructions received from the City, the City may take such action as it deems appropriate to control erosion and sediment transport at the Developer's expense. The City will endeavor to notify the Developer in advance of any proposed action, but failure of the City to do so will not affect the Developer's and City's rights or obligations hereunder. No development will be allowed and no building permits will be issued unless the plat is in full compliance with the erosion and sediment control requirements. Erosion and sediment control needs to be maintained until vegetative cover has been restored, even if construction has been completed and accepted. After the site has been stabilized to where, in the opinion of the City, there is no longer a need for erosion and sediment control, the City will authorize the removal of the erosion and sediment control, i.e. hay bales and silt fence. The Developer shall remove and dispose of the erosion and sediment control measures. 8a. Erosion Control During Construction of a Dwelling or Other Building. Before a building permit is issued for construction of a dwelling or other building on a lot, a $500.00 cash escrow or letter of credit per lot shall also be furnished to the City to guarantee compliance with City Code § 7-22. 208738v2 GC-3 9.

The appropriate contractor waivers shall also be provided. Final acceptance of the public improvements shall be by City Council resolution. 11. Claims. In the event that the City receives claims from laborers, materialmen, or others that work required by this Contract has been performed, the sums due them have not been paid, and the laborers, materialmen, or others are seeking payment out of the financial guarantees posted with the City, and if the claims are not resolved at least ninety (90) days before the security required by this Contract will expire, the Developer hereby authorizes the City to commence an Interpleader action pursuant to Rule 22, Minnesota Rules of Civil Procedure for the District Courts, to draw upon the letters of credit in an amount up to 125% of the claim(s) and deposit the funds in compliance with the Rule, and upon such deposit, the Developer shall release, discharge, and dismiss the City from any further proceedings as it pertains to the letters of credit deposited with the District Court, except that the Court shall retain jurisdiction to determine attorneys' fees. 12.

These conditions must then be complied with within two (2) months after the certificate of occupancy issued, except that if the certificate of occupancy is issued between October 1 through May 1 these conditions must be complied with by the following July 1st. Upon expiration of the time period, inspections will be conducted by City staff to verify satisfactory completion of all conditions. City staff will conduct inspections of incomplete items with a $50.00 inspection fee deducted from the escrow fund for each inspection. After satisfactory inspection, the financial guarantee shall be 208738v2 GC-4 returned. If the requirements are not satisfied, the City may use the security to satisfy the requirements. The City may also use the escrowed funds for maintenance of erosion control pursuant to City Code Section 7-22 or to satisfy any other requirements of this Contract or of City ordinances. These requirements supplement, but do not replace, specific landscaping conditions that may have been required by the City Council for project approval. 14. Warranty.

Consistent with the Carver County Comprehensive Plan, policies, and related studies, the following are comments and recommended conditions of approval and potential requirements for any necessary permits to be issued for the project: 1. CR 117/Galpin Blvd. ownership and maintenance is planned to be turned over from Carver County to the City of Chanhassen in 2023 and was studied as part of a Highway 117 Corridor Study. The proposed 50 feet of right of way from the highway centerline, 100 feet total, as shown on the proposed plat along CR 117/Galpin Blvd. is consistent with the Highway 117 Corridor Study and as established per The Park 1st Addition. 2. CR 117/Galpin Blvd. is identified in Carver County’s Comprehensive Plan with access spacing guidance in Category 6B - Urban/Urbanizing Collector, which guides access spacing at 1/4- mile full access and 1/8-mile secondary access. The proposed access across from Longacres Drive, named Pearl Drive in the proposed plat, meets this guided access spacing and was also identified in the corridor study. 3. Exclusive left and right turn lanes will be required at the access point across from Longacres Drive, named Pearl Drive in the proposed plat. These are shown conceptually in the preferred alternative from the Highway 117 Corridor Study. 4. The plat’s final grading plans and stormwater ponds along CR 117/Galpin Blvd. will need to be reviewed and approved to show how this is set up for the potential future CR 117/Galpin Blvd. reconstruction project. A cross reference of grading plans, profiles, and respective cross sections should be provided at key locations such as intersections, ponds, or other special features. a. Carver County requests a meeting with City of Chanhassen staff to review and verify the stormwater ponds needed for the related Galpin Blvd. reconstruction project to make sure the final grading plan within this plat is compatible. 5. For traffic control management, additional provisions are required: a. The temporary one lane road with flaggers will only be allowed during the day when 2 | P a g e work is actively taking place. Both directions of traffic need to be restored when flaggers are not on site. b. A Be Prepared to Stop sign should be added to the temporary traffic control layout. c. Make the detour signage for Longacres Drive more robust to better convey the route for local residents to use when the intersection is closed. 6. Regarding the utility crossings of CR 117/Galpin Boulevard, additional provisions are required: a. Carver County typically requires utility crossings to be within a steel casing. Since this highway is planned to be turned over to the City of Chanhassen, Carver County would like to understand the city’s preference and to ensure that any utility crossing is compatible with the planned reconstruction project. b. Clarify if existing watermain is being removed. 7. The technical details of the plat, its boundaries and form(s) will need to be reviewed and approved by the County Surveyor. 8. Prior to any work affecting or on County highways or in County right of way, the applicant shall coordinate plans with the County Engineer and obtain a Utility or Excavating/Filling/Grading Permit(s) from Carver County Public Works: (http://www.co.carver.mn.us/how-do-i/apply-for/a-permit). Final details of locations, grades, and profiles affecting County roads as well as any utility connections will need to be reviewed and approved prior to any permits. 9. Any damages, modifications, or changes incurred on Carver County highways from current or approved conditions will need to remedied or updated at development expense, including costs incurred by Carver County. These are comments at this time. If you have any questions or need further assistance, please do not hesitate to contact me at dmccormick@co.carver.mn.us or by phone at (952) 466-5208. Sincerely, Dan McCormick, P.E. PTOE Transportation Manager Carver County Public Works
