This fall we were very surprised to see numerous evergreens planted around the tennis courts which should provide a much improved buffer. We appreciate that follow up and look forward to ensuring that these take good root this next year. In addition, we have reviewed the new proposal for the widening of the drive lane and the other site grading changes proposed for MMW (public hearing tonight). In general, we agree with the recommendations made by City staff should the project move forward. As a neighborhood, we discuss concerns about the increased traffic on 41 and the speed of the traffic especially around the school and cross walk at Chaska Rd. Has the City or MnDOT studied the impact of reducing the speed limit on highway 41 as a way to better manage the congestion and safety?

As a neighbor to this property, I am generally supportive of the proposal and the recommendations of the city staff. Of particular importance to me and my neighbors is the landscaping plan which was absent in the proposal. I am glad that the staff highlighted this in the report and made the submittal of a plan mandatory. Although we could not determine if the staff was recommending a landscaping plan that was under the minimum code requirements. We would strongly recommend that the landscaping plan at least meet the code minimum if not exceed it. Exceeding the code minimum would be welcomed considering that the parking lot is replacing an area that has substantial natural plants, trees and other wildlife. In addition, we would like to recommend that the City and School review this landscaping and the rest of the landscaping around the tennis courts for a period of at least 2 years to ensure that the landscaping has successfully taken root. We have been very disappointed in the landscaping that was done during the development of the tennis courts a few years ago where —5 evergreen trees were planted too close to the perimeter fence and the majority of them died within 1 year and were never replaced. The result is now a series of dead evergreens surrounded by invasive buckthorn and other invasive vines which do not achieve a good landscape buffer for the large chain link fencing associated with the courts. I appreciate your consideration and that of the council of our concerns and look forward to hearing the response.

PROPOSAL/SUMMARY The applicant is proposing 2,100 cubic yards of grading for site improvements that include expansion of the existing driveway access to Highway 41. Planning Commission Minnetonka Middle School West IUP — Planning Case 2016-03 January 19, 2016 Page 2 of 6 APPLICABLE REGULATIONS Chapter 7, Article Il, Excavating, Mining, Filling and Grading Chapter 19, Article VII, Surface Water Management Chapter 20, Article IV, Division 5, Interim Use Permits Chapter 20, Article XXI, "OP' Office and Institutional District BACKGROUND On January 27, 2014, the Chanhassen City Council approved Interim Use Permit #2014-01 for site grading in excess of 1,000 cubic yards to allow a parking lot expansion and stonnwater improvements on the south side of the school building as part of the swimming pool project within the building. On January 24, 2011, the Chanhassen City Council approved the interim use permit to permit site grading for the tennis courts at Minnetonka Middle School West, Planning Case #2011-01. On February 27, 2006, the Chanhassen City Council approved Interim Use Permit #2006-03 to permit the grading of approximately 3,400 cubic yards for an infiltration basin and drainage swales to reduce downstream erosion and sedimentation along Highway 41. On June 9, 2003, the Chanhassen City Council approved Interim Use Permit #2003-02 to permit grading in excess of 1,000 cubic yards to install a storm water pond and reconfigure the bus circulation route and parking area on the north side of the school.

The proposed project includes widening the driveway, drainage improvements by the pond near the tennis courts and at the southwestern corner of the building and parking lot improvements. The existing driveway for the school is a crowned drive that directs runoff to the gutter on either side of the roadway where it is collected at catch basins to enter the stormwater system for this part of TH 41. The proposed widened driveway design shall add a drainage structure along the new gutter line of the widened drive which will tie into this same system. MnDOT will require a drainage permit for this work. The applicant's engineer shall adjust the slope of the expanded drive lane to convey runoff to the northeast gutter line before entering the catch basins. The main parking lot existing drainage is served by several catch basins to collect the runoff for discharge into the stormwater pond near the tennis courts. Grading changes are proposed for this parking lot but the catch basin elevations will be adjusted with the parking lot mill and overlay. The southwest comer of the school's recent addition has been experiencing some drainage issues, with water ponding near the corner of the building. The applicant has proposed constructing a concrete valley gutter on the South Drive from near the building corner to the catch basin that was originally intended to collect that run-off. While a valley gutter would likely alleviate the drainage issue, staff is concerned about the long-term maintenance implications such as pavement heaving or cracking bituminous when placing a concrete material in the bituminous drive lane. Staff recommends examining other methods to direct stormwater away from the building. The plan set shall be revised to consistently show the proposed and existing contours updated since the last IUP was issued. An as -built grading plan is required at the completion of site grading to ensure compliance with the approved grading plan. Staff will require that the applicant provide a proposed haul route for review and approval. EROSION CONTROL The applicant shall submit an erosion control plan for this work per City Code 19-154 that shall include, but not be limited to, silt fence on downslopes and inlet protection for nearby structures. A $5,000 escrow to guarantee restoration and erosion control measures will be required with the permit. STORMWATER UTILITIES The project will also include construction of draintile, two new catch basins and a stormwater pipe near the pond and tennis courts. This new system will tie into an existing catch basin that outlets into the stormwater pond. The plans must be revised to label the catch basins to match the CB/MH Schedule on Page C5. Slopes shall be labeled on all proposed pipes. The note for the draintile shall be revised so that no sock is used on the draintile. It is city staff's experience that a sock will clog with sediment and prevent the draintile from functioning per design. Planning Commission Minnetonka Middle School West IUP — Planning Case 2016-03 January 19, 2016 Page 4 of 6 117N\�I�►'d/\L The school's driveway provides the school direct access to TH 41. The city has received comments from MnDOT on how this project will tie into their Trunk Highway. The applicant shall review MnDOT's letter, included in the staff report. The design shall be revised to incorporate MnDOT comments, which are summarized below: • The mill and overlay project would trigger ADA improvements at TH 41 including completing the trail to the corner along with a pedestrian curb ramp. • The plans don't show the crosswalk pavement markings being replaced. • A drainage permit is required. • The proposed development will need to maintain or reduce existing drainage rates to MnDOT right of way. • The project developer will need to submit the most current construction plans and existing/proposed hydraulic computations for the 10 and 100 -year rainfall events verifying that all existing drainage patterns and systems affecting MnDOT right of way will be perpetuated. • A work in right of way permit is required. On the west side of TH 41, opposite the school's driveway, the Beehive Homes 2nd Addition is under construction. When construction is complete, its access will be aligned with the school's driveway access. In the future, that access is intended to become a public street when the adjacent property is developed. Staff recommends the applicant consider pavement markings at the access at TH 41 to accommodate the through movement. PARKING LOT The parking spaces and aisles must be adjusted to meet the Chanhassen City Code requirements of 9 -foot by 18 -foot minimum stall dimensions, as well as the 26 -foot wide driving aisles for 90 - degree parking spaces. Figure 1: Proposed Traffic Flow The applicant has submitted a layout showing the proposed traffic flow at peak times (See Figure 1). The outside travel loop will accommodate busses, while the parking area inside the parking islands will be for automobile traffic. The parking lot plan includes installation of vehicle gates at the northeast and southeast comers of the parking lot to assist with maintenance access. The applicant has also indicated that the vehicle gates may be used to accommodate longer queue lengths during peak times (not shown on the proposed traffic layout). Planning Commission Minnetonka Middle School West NP — Planning Case 2016-03 January 19, 2016 Page 5 of 6 The existing parking lot layout includes a pedestrian -friendly island to provide sidewalk for pedestrians traveling north -south through the parking lot (See Figure 2). The proposed parking lot design would eliminate the pedestrian travel island and extend the parking spaces in an east -west row. The design shall be revised to provide a travel path for north -south pedestrians. The plan must follow all applicable State and Federal guidelines, including ADA standards for the sidewalk reconstruction. LANDSCAPING Minimum requirements for the parking lot landscaping at Minnetonka Middle School West include installing two landscape islands within the reconfigured parking area to replace the existing landscape island proposed to be removed. Landscape islands are required in all parking lots. Each island shall have an interior perimeter width of 10 feet and contain two trees each. The islands are required by ordinance and correspond to the existing parking lot landscaping on site. RECOMMENDATION Staff recommends that the Planning Commission approve the interim use permit to permit grading in excess of 1,000 cubic yards to allow a parking lot alteration, widen the main entrance/exit driveway and stormwater improvements subject to the following conditions: 1. The applicant's engineer shall adjust the slope of the expanded drive lane to convey runoff to the northeast gutter line. 2. The plans must be revised to label the catch basins to match the CB/MH Schedule on Page C5. 3. Slopes shall be labeled on all proposed pipes. 4. The note for the draintile shall be revised so that no sock is used on the draintile. 5. The applicant shall submit an erosion control plan (including additional detail plates) for this project per City Code §19-154.

On January 19, 2016 the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Minnetonka Public Schools District 276 for an interim use permit to allow a parking lot alteration, widen the main entrance/exit driveway, and stormwater improvements for the property located at 6421 Hazeltine Boulevard. The Planning Commission conducted a public hearing on the proposed interim use which was preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned OI, Office Institutional District. 2. The property is guided by the Land Use Plan for Public/Semi-Public use. 3. The legal description of the property is: The Southwest Quarter (SW '/) of the Northwest Quarter (NW '/) of Section Three (3), Township One Hundred Sixteen (116), Range Twenty Three (23) West, according to the U.S. Government Survey thereof, excepting therefrom the 35/100ths acres conveyed by deed recorded in the office of the Register of Deeds of Carver County, Minnesota, in Book 8 of Deeds, page 400, and that part thereof conveyed by deed recorded in the office of the Register of Deeds of Carver County, Minnesota, in Book 41 of Deeds, page 322, and subject to the right, title and interest of the State of Minnesota in that strip of land conveyed by deed recorded in the office of the Register of Deeds of Carver County, Minnesota, in Book 33 of Deeds, page 25. Also, that part of Lot E, Bardwell Acres, not conveyed by said deed recorded in the office of the Register of Deeds of Carver County, Minnesota, in Book 41 of Deeds, page 322. Subject to a permanent easement for roadway purposes as recorded in the office of the Register of Deeds of Carver County, Minnesota, in Book 64 of Deeds, page 32. 4. When approving an interim use permit the city uses the standards for a conditional use permit, the city must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: a. The grading operation will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. The site work will result in the creation of a better queuing opportunity at the site exit, alter parking and improve the storm water management system which will improve water quality. b. The grading operation will be consistent with the objectives of the city's comprehensive plan and the zoning code providing additional storm water treatment. The earthwork will be maintaining the site in a form suitable for institutional use which is compatible with the Comprehensive Plan and the zoning code. c. The grading operation will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area because the site improvements will improve the use of the site as well as improve water treatment. d. The grading operation will not be hazardous or disturbing to existing or planned neighboring uses because the grading and drainage will be contained within the site perimeters. Hours of operation are limited and specific conditions of approval will be in place and enforced by the city. e. The grading operation will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use. The grading is temporary which does not need to be served by public facilities and services. The proposed grading will improve storm water management in this area. The grading operation will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community since this site already contains a school. g. The grading operation will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare due to excessive production of traffic, noise, smoke, flumes, glare, odors, rodents, or trash. The conditions of the approval will provide standards by which the activities should be minimized. h. The grading operation will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. Through the use of signage, limits on the hours of operation, and the limited nature of the operation, traffic impacts will be limited. The grading operation will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. The grading operation is limited. 2 j. The grading operation will be aesthetically compatible with the area since the grading and re -vegetation of the site will improve the site storm water management. k. The grading operation will not depreciate surrounding property values since the plan will improve the site and its impacts on the surrounding properties. 1. The grading operation will meet standards prescribed for certain uses as provided in Chapter 7, Article III of the Chanhassen City Code. 5. The planning report #2016-03 dated January 19, 2016, prepared by Stephanie Smith, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the interim use permit to permit grading in excess of 1,000 cubic yards to allow a parking lot alteration, widen the main entrance/exit driveway and stormwater improvements.

Or at least a link directly to the plan? I went to Chanhassen City's project page and was unable to find a plan for the widening of the entrance/exit to MMW. Specifically, I'm interested in knowing how many trees will be removed from MMW property. But I'm interested in the overall plan as well. I'm concerned with the timing of this plan. We've lived at 6405 Melody Lane since 1999. Our house is adjacent to the entrance/exit to MMW. I was living here during the last changes to the entrance/exit and parking lot. It was a nightmare. We were unable to be outside almost the entire summer due to noise and dirt. Allowing more and more cars at Minnetonka Middle School West is not the solution. Widening the driveway is not the solution. There are too many cars coming to the school after school and there are too many cars on Highway 41. A signal light at the entrance/exit to the school would be a better solution. Limiting the number of cars at the school would be a better solution. Eliminating unused buses would be a better solution. As long as the only entrance/exit to Minnetonka Middle School West is Highway 41, there will be traffic issues at MMW in the morning and the evening. Highway 41 is very busy, talk to the State Patrol who direct traffic from Westwood Community Church at certain times during the week. Please do more work in understanding this issue. It has been ongoing for over 20 years. New people come into jobs and think they have the answers. Look at the history. This isn't a new issue. Concern today is the lack of outdoors our children are in. How much more green space is MMW going to give up? MMW is a school more concerned about cars and buses than the outdoor appeal and education of children. At least talk to the State Patrol and see what the officers that direct traffic on Highway 41 suggest.

Sincerely, Karen Sebeffing Principal Planner Copy sent via E -Mail: Nancy Jacobson, Design Hailu Shekur, Water Resources David Sheen, Traffic Clare Lackey, Traffic Engineering Doug Nelson, Right -of -Way Jeff Dierberger, Permits Diane Langenbach, Area Engineer Russell Owen, Metropolitan Council MnDOT ]Drainage Permits Cheeklist Purpose of the MnDOT Drainage Permit MnDOT Metro District regulates activities that impact its drainage systems and its MS4 regulated area. The purpose of the Drainage Permit is to protect State of Minnesota investment in infrastructure including but not limited to roadways, storm water treatment basins, ditches and storm sewer systems. Excess storm water and/or sediment laden storm water added to MnDOT's drainage systems leads to degradation of these assets. Negative impacts include but are not limited to: sediment deposition, loss of flood storage capacity and also loss of hydraulic conveyance capacity. These impacts may cause premature flooding of the road surface and/or erosion damage on State right-of-way. Technical Requirements of the MnDOT Drainage Permit The permit applicant shall demonstrate that offsite runoff coming to MnDOT drainage system and/or right-of-way will not increase as a result of the proposed project. This is quantified as a "no increase in discharge" criteria for the 2 -year, 10 -year and 100 -year storm events. Compliance is demonstrated by applying hydraulic/hydrologic software models. HydroCAD and XPSWMM are the approved models to compare the pre and post project discharge values. Typically, HydroCAD is sufficient to model most proposed projects. However, XPSWMM may be required if the project contains extensive storm water pipe systems connected to MnDOT storm sewer or if HydroCAD cannot in MnDOT's judgment effectively model pressure flow, complex junctions and/or backwater effects that are present. The 2 -year, 10 -year and 100 -year storm events shall be based upon Atlas 14 runoff amounts per the NOAA website. In addition, Drainage Permit Applicants shall meet all applicable water quality treatment requirements established by the local Watershed District(s) and the MPCA. Permit applicants should anticipate that specific projects that seek to divert runoff to another sub -watershed or watershed will be denied. It is MnDOT practice to avoid such watershed diversions whenever practicable. Submittal Requirements- Readable/legible watershed maps that show pre and post project drainage conditions. These two separate contour maps shall be large enough in scale so that approximate flow paths can be determined for verifying the Time of Concentrations used in the models. The drainage/watershed maps shall include enough detail so that Curve Numbers used in the hydraulic models may be verified by MnDOT. April 2014 • Surface water flow direction and storm water pipe water flow direction shall be indicated on the pre and post project watershed maps. Minimum recommended watershed map scale is,]" =100'. Project applications submitted with smaller scales (e,g., 1"=500') may be rejected and returned to the applicant. The same would apply for project watershed maps that do not include topographic contours or basic land use information such as the location of buildings, pavement and "green space". Watershed maps submitted as pdf files or CAD files shall be readily printable at scales that allow for good readability. • 'Pre and post project watershed maps shall be clearly linked to the drainage models such that the names of the sub -watersheds, ponds and drainage structures are the same in the models as shown on the watershed maps. In addition, watershed and sub -watershed boundaries shall be clearly shown. • Submission of the actual pre and post project HydroCAD or XPSWMM models is required: pdf copies of the drainage model simulations are unacceptable. In the event that the models cannot be transferred readily by electronic mail or electronic repository site, a hardcopy CD shall be provided. • Curve numbers shall be determined per NRCS methodology and should be modified as needed based upon detailed knowledge of soil type and specific conditions on site. HydroCAD modeling software includes NRCS guidance for determining curve numbers based upon land use and condition. • Time of concentration (Tc) computations and assumptions that in MnDOT's assessment clearly overestimate or underestimate this critical runoff parameter will be rejected. Two common assumptions that lead to overestimating Tc include: using the "Lag/CN" method to determine peak runoff from watersheds that have a relatively long and/or diverse flow path, and assuming that sheet flow occurs for a distance exceeding100 feet. Conversely, pre -project Tc shall not be underestimated to offset post project increases in peals discharge. • Available freeboard for existing and proposed treatment ponds shall be shown on the watershed maps as well as the normal and 100 -year high water levels. All proposed pond treatment systems along MnDOT right-of-way shall have a minimum freeboard of 2.0 feet between the road surface and the proposed 100 -year HWL. • Infiltration basins, filtration basins and ponds adjacent to MnDOT right-of-way shall be designed to provide at least 2 feet of eleyation difference between the 100 -year HWL and the crest of the basin berm. The berm crest shall be at least 5 feet wide. The emergency overflow shall be lined from crest to toe of slope with Turf Reinforcement mat or Category 6 or 7 Erosion Control Blanket. April 2014 • Best management practices (BMP's) including infiltration/filtration sites, storm water ponds, etc. shall be clearly labeled on the pre and post project watershed maps. • Plan sheets submitted as watershed maps shall be evaluated as such. They shall be readable and legible and meet all the same requirements including clear delineation of watershed boundaries, readable map scale, and land use shown by an aerial photo background map, or that is clearly depicted based on details on the plan sheet or sheets submitted. Project plan sheets relevant to the Drainage Permit are required and include: existing site conditions, the proposed grading plan as well as proposed site drainage system plans and profiles. The plans shall include applicable wetland impact/mitigation features and temporary sediment and erosion control measures for the project. In addition, erosion control blanket will be used to stabilize disturbed area on MnDOT right-of-way unless other methods such as rip -rap treatment are called for in the plans and approved by MnDOT. • Pond and basin special structures including weirs and orifices shall be consistent with what is used in the HydroCAD or XPSWMM models submitted and include relevant calculations/details. • A table summary of existing versus proposed site discharge to MnDOT drainage system/right-of-way is required for the 2 -year, 10 -year and 100 -year Atlas 14 rainfall events. • Post project storm water discharge to WDOT ditches or other open channel shall be limited to flow velocities of 6 fps or less for a 50 -year Atlas 14 rainfall event. • Project discharge points that will connect to MnDOT ditch or channel shall be located such that they do not cause erosion or conflict with the grade of the existing ditch or channel. • Proposed access road culverts on MnDOT right-of-way shall be designed for the 10 -year Atlas 14 rainfall event unless they are part of a significant drainage ditch along the roadway in which case a 100 -year or 50 -year design will apply. • Direct connections to MnDOT storm system shall be avoided. Connection to open ditch, or channel is preferred. If direct storm sewer connections cannot be avoided, it is the applicant's responsibility to provide a good connection typically via a new structure. Furthermore, MnDOT offers no warranty that there will not be a hydraulic backwater effects on the new storm line upstream that is connected to MnDOT's existing storm sewer. April 2014 • For all disturbed areas that sheet flow to MnDOT right-of-way and any disturbed areas within MnDOT right-of-way, either Erosion Control Mat or Bonded Fiber Matrix shall be used for temporary/permanent erosion control. • Silt fence shall not be used for erosion control at the proposed project site perimeter. Rather, continuous Wood Chip or compost Sediment Control Logs shall be implemented. Permit applicants are encouraged to contact MnDOT Metro Water Resource Engineering with questions/concerns. Questions posed early in the permit application process help to avoid project delays. This is particularly true for large project Drainage Permits with significant complexity.
