Building permits are required for all retaining walls four feet tall or higher and must be designed by a Structural Engineer registered in the State of Minnesota. A fence must be placed at the top of the wall for safety. The exits in front of Wall 2 may be inadequate for some uses of the building under the proposed parking scenario. Exterior exit discharge must accommodate exits served. The parking stalls in this area should be constructed at the time when a final end user is determined so that the exits will not limit the occupancy. 8. The wall and wall supports (not including soil) in drainage area three on the east side of the site must be removed from the drainage and utility easement. 9. Details must be provided for all proposed storm sewer, sanitary sewer, and watermain crossings. Actual elevations of existing utilities shall be verified for accuracy. A minimum vertical separation of 18" is required at all storm, sanitary, and watermain crossings. 10. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to provide the City with the necessary financial security in the form of a letter of credit or cash escrow to guarantee the installation of the storm sewer, erosion control, and seeding. This amount will be determined prior to start of construction due to the possible phasing of the project and not knowing the amount to be installed and disturbed. 11. The applicant must also notify the City after installation of the erosion control and 48 hours prior to the commencement of grading. Permits from the appropriate regulatory agencies will be required. 12. The plans and drainage calculations must be signed by a professional engineer registered . in the State of Minnesota. Enclosed is a site plan permit that must be executed by CSM Corporation. Note that if there is a different property owner and/or mortgage holder on the property, they will need to sign the consent(s) at the end of the permit. Return the permit to me for City execution and recording at Carver County within 120 days of the approval (by January 12, 2012). The revised plans as specified in the conditions of approval and the required security specified in the site plan permit ($10,000.00) shall be submitted prior to the City issuing a notice to proceed. All erosion control measures and tree protection fencing must be installed and inspected prior to the City authorizing grading operations. A copy of the executed permit will be returned for your files.

City Council approval requires a majority vote of City Council present. EXECUTIVE SUMMARY The applicant is proposing a 155-space expansion of the site parking. However, due to revisions to the plan resulting from the conditions of approval, such as providing additional landscape islands and moving the retaining wall out of the eastem drainage and utility easement, the final number of additional parking spaces is not determined. The parking lot installation is anticipated to be completed in three stages and will be responsive to economic conditions. PLANNING COMMISSION SUMMARY The Planning Commission held a public hearing on August 16, 2011 to review the proposed plan. The Planning Commission voted six for and none against a motion recommending that City Council approve the site plan subject to the conditions of the staff report. There were no issues or concerns regarding the proposed parking lot expansion. The Planning Commission minutes are item la of the September 12, 2011 City Council packet.

We are concerned about the addition of 150 parking spaces being added to this lot. Our primary concern is with the spaces located at the intersection of Powers and Lake Drive. These will fall directly in the view corridor from our lot to Lake Susan Park. We have no problems with any of the other lot expansions. Since our intersection is already built we will have to build a road north east from that intersection parallel to Powers Dr to access our lot (as seen on PID map attached). When leaving our lot you will look right at those new parking spaces as you drive down to the intersection from our build -able area. Please include this in the meeting minutes.

SUMMARY OF REQUEST: The applicant is requesting Site Plan Review for a 155-stall parking lot expansion for the Lake Drive Business Center building. LOCATION: 950 Lake Drive Lot 1, Block 1, Empak Addition (PID 25-2710010) APPLICANT: CSM Corporation Attn: John Ferrier 500 Washington Avenue South, Suite 3000 Minneapolis, MN 55415 (612)395-7000 iferrier@csmcorp.net PRESENT ZONING: Industrial Office Park (IOP) 2020 LAND USE PLAN: Office Industrial ACREAGE: 12.6 acres DENSITY: 0.35 F.A.R. LEVEL OF CITY DISCRETION IN DECISION -MAKING: The City's discretion in approving or denying a site plan is limited to whether or not the proposed project complies with Zoning Ordinance requirements. If it meets those standards, the City must then approve the site plan. This is a quasi-judicial decision. PROPOSAL/SUMMARY The applicant is proposing a 155-space expansion of the site parking. The applicant believes that this parking expansion makes the building more marketable to office and warehouse tenants. They have been in contact with potential tenants who have expressed a concern about the lack of parking near the office portion of the building, which is located on the west end of the building. Additionally, the parking expansion permits greater flexibility for additional office space within the building. The parking will be installed in phases with the parking immediately southwest of the Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 2 of 10 building being installed first. The parking in the southeast portion of the building will be installed second, and the parking on the east end and the truck loading/maneuvering area will be installed third. However, should a large user be found all the parking could be installed in one phase. Some of this parking (located east of the building) was previously shown as part of a building expansion approved in 2000, but was held in proof of parking status. However, the proposed parking lot expansion and the resulting grading operation exceeded the amount that could be approved by staff administratively (1,000 cubic yards). The City may approve site grading through the site plan review process, the interim use process or as part of a subdivision. Since the proposal includes both landscaping, sign relocation and site lighting review in addition to the grading and parking lot expansion, the site plan review process is appropriate. With this site plan, they will have all their approvals in place for construction of the parking lot expansion. The property to the east is Roberts Automatic Products, another industrial user. Lake Susan Park is located south across Lake Drive. To the west across Powers Boulevard is a vacant office/industrial site. To the north are the railroad tracks at the top of a steep slope (elevation 946), 35 feet above the finished floor elevation of the building (elevation 911). To the southwest, the proposed parking expansion will be approximately seven feet above the corner of Powers Boulevard and Lake Drive. The site is served by City sewer and water service. Access is via Lake Drive with two driveways. Truck access is limited to the easterly driveway. The building is currently estimated to have the following breakdown of space usage: Office — 16,500 square feet, manufacturing area — 78,760 square feet and warehouse — 96,925 square feet. When the site plan was originally approved in 1989, the parking requirements for an office use were 3 spaces per 1,000 square feet of building area. At the time of the building expansion in 2000, City of Chanhassen's standards were 4.5 spaces per 1,000 square feet. Based on the parking requirements, the site needed the following parking: Office — 74 spaces, largest shift — 65 spaces, warehouse — 54 spaces. The total spaces needed were 193 spaces. There were ample locations to incorporate additional parking on site. At that time, staff visited the site on two different occasions and noticed that approximately one-half of the parking was occupied. The City permitted 30 percent of the parking (58 stalls) in proof of parking pursuant to section 20- 1124 (1) of the City Code. These spaces are located along the east side of the building. If parking had become a problem, the City could have required the installation of the additional parking spaces. Staff is recommending approval of the site plan subject to the conditions of this staff report. APPLICABLE REGUATIONS Section 20-106 — 20-116, Site Plan Review Section 20-811— 20-816, IOP District Regulations Section 20-1116 — 20-1124, Parking and Loading Section 20-1176 — 20-1183, Landscaping and Tree Removal Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 3 of 10 BACKGROUND On November 14, 2000, the Chanhassen Planning Commission as the Board of Appeals and Adjustments approved a six (6) foot variance from the 50-foot height limitation for the construction of storage silos. On August 28, 2000, the Chanhassen City Council approved Site Plan #2000-10 for a 96,925 square -foot expansion to a 95,260 square -foot building. On April 24, 1989, the Chanhassen City Council approved the plat of Lot 1, Block 1, Empak Addition, replatting Lots 1 and 2, Block 2, Chanhassen Lakes Business Park 2nd Addition. On April 10, 1989, the Chanhassen City Council approved site plan #89-1 for a 77,690 square - foot office and production facility. GENERAL SITE PLAN The applicant is proposing a three-phase, 155-space expansion of the site parking. The parking expansion southwest of the building is proposed to be installed first; the parking in the southeast portion of the building installed second; and the parking on the east end and the truck loading/maneuvering area installed third. Parking lot landscaping, parking area lighting and extensive retaining walls are included as part of the plan. The sign in the southwest comer of the building will be relocated further north on Powers Boulevard. ACCESS Access to the site is provided from Lake Drive via two existing driveways. No additional street access is being proposed. GRADING AND DRAINAGE This 12.6-acre site is located in Empak Addition which is on the northeast corner of Powers Boulevard and Lake Drive. A 188,900 square foot building with parking is currently on the site. Beyond the parking and building areas is grass. This development is located in the Bluff Creek Watershed District. Grading will take place on the site to prepare the parking areas. The grass area maximum slope must not exceed 3:1. Runoff from this site will be treated using an underground treatment system. The drainage and storm sewer system within the site is privately owned and must be maintained by the owner. Existing runoff rates must be maintained for the 2-, 10- and 100-year rain events. The drainage Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 4 of 10 calculations do not match the plans. The applicant must submit revised plans and calculations meeting City requirements. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. Erosion and Sediment Control The applicant has prepared an erosion control plan for all phases of this project. The first phase of this project will result in 3:1 slopes with a positive grade towards Lake Drive. This disturbed area will need to be covered with erosion control blanket or sod within 14 days of cessation of work. This should be indicated in the plan. Other than the need for blanket or sod on all 3:1 slopes, the plan appears adequate for existing conditions. However, a note must be added to the plan that additional best management practices may be necessary as site and climatic conditions change throughout construction. To assure that erosion and sediment control best management practices are installed and maintained, an escrow or letter of credit in the amount of $2,450 will be required with the first phase. This number was calculated based upon 450 feet of silt fence, three (3) inlet protection devices, and 370 yards of blanket and seed. Storm Water Management The applicant is proposing to construct 155 new parking stalls in three areas. These parking areas are to be phased in with only the most southwesterly parking area being constructed with the first phase. The applicant is proposing to utilize perforated storm sewer and embedded within a rock trench to achieve rate control and some pre-treatment of the runoff. Water from this site is directed to Lake Susan pond (LS-P3.34). Approximately 150 acres of commercial and industrial land use is also directed to the Lake Susan Pond. This water is routed through three primary storm sewer conveyance routes. Powers Boulevard from MN T.H. 5 to Lake Drive is routed through a 30-inch RCP along Powers Boulevard. Chanhassen Retail Addition is routed through a 36-inch RCP immediately east of the subject property. The third area drains through a 30-inch RCP along Lake Drive and accepts drainage from Lake Drive as well as the intersection of T.H. 5 and MN T.H. 101. Because of the size of the drainage area being conveyed through these pipes, the applicant must either model the entire watershed to Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 5 of 10 show that there is adequate capacity in the pipes or maintain, or preferably decrease discharge rates to the system. While this system is generally acceptable, it is undetermined at this time how it will be maintained. The City has required, and the consulting engineer has agreed to provide, a long- term operations and maintenance plan for this system. This system will remain private and the land owner will be responsible for the maintenance of the system. With proper lead time, staff has indicated to the applicant's engineer that the City would have an interest in working with the applicant to procure grant funds and partner or accept cash in lieu of installation of the pretreatment features being proposed. Because of the existing infrastructure and size of the contributing watershed, rate control must be achieved on site. However, the City would still have an interest in partnering with the applicant and other agencies to implement some alternative storm water BMPs. WETLANDS AND SHORELAND No wetlands appear to exist on or immediately adjacent to the proposed project area. Although the subject property is tributary to both Lake Susan and Riley Creek, it lies outside of the shoreland overlay district for both of these water bodies. RETAINING WALLS The proposed retaining walls are as follows: Location Length (approx.) Maximum Height a rox. Southeast comer parkingarea 1 Wall 1 70 feet 2.5 feet North side of parkingarea 2 — 5' from the buildingWall 2) 430 feet 6.8 feet East side of parkingarea 3 Wall 3 360 feet 8.8 feet North side of parking area 4 Wall 4 330 feet 17.5 feet Building permits are required for all retaining walls four feet tall or higher and must be designed by a Structural Engineer registered in the State of Minnesota. The exits in front of Wall 2 may be inadequate for some uses of the building under the proposed parking scenario. Exterior exit discharge must accommodate exits served. The parking stalls in this area should be constructed at the time when a final end user is determined so that the exits will not limit the occupancy. The wall and support structure (not including soil) in Parking Area 3 must be moved outside of the City utility easement. A 36-inch diameter storm sewer is within this easement. Moving the wall in this area will cause a reduction in the number of parking stalls. Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 6 of 10 UTILITIES Details must be provided for all proposed storm, sanitary, and watermain crossings. Actual elevations of existing utilities shall be verified for accuracy. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to provide the City with the necessary financial security in the form of a letter of credit or cash escrow to guarantee the installation of the storm sewer, erosion control, and seeding. This amount will be determined prior to start of construction due to the possible phasing of the project and not knowing the amount to be installed and disturbed. The applicant must also notify the City after installation of the erosion control and 48 hours prior to the commencement of grading. Permits from the appropriate regulatory agencies will be required. LIGHTING/SIGNAGE The applicant is proposing parking lot lighting as part of the parking area expansion. The photometric plan describes the use of 25-foot poles, which would comply with city requirements that restrict pole height to 30 feet. City code requires that all fixtures must be shielded, high- pressure sodium or light -emitting diode (LED) with a total cutoff angle equal to or less than 90 degrees. The applicant is proposing relocating the monument sign on the site. This relocation will require a separate building permit and sign permit. Such sign shall not exceed 64 square feet in display area nor be greater than eight feet in height. The proposed monument sign is shown 35.7 feet from the westerly property line. LANDSCAPING/TREE PRESERVATION Minimum requirements for landscaping include 472 square feet of landscaped area around the parking lot, two trees for the parking lot, and bufferyard plantings along Lake Drive, as well as neighboring property lines. The applicant's proposed as compared to the requirements for landscape area and parking lot trees is shown in the following table. Required Proposed Vehicular use landscape area 12,655 square feet >12,655 square feet Trees/ parking lot 50 overstory trees 14+ existing (not shown on plans) Landscape islands or peninsulas required 16 7 Bufferyard B — S. property line Adequate screening in accord with existing buffer plantings Screening needs revision Planning Commission Lake Drive Business Center Site Plan — Planning Case 2011-08 August 16, 2011 Page 7 of 10 Applicant does not meet minimum requirements for parking lot landscape islands/peninsulas or required trees. The applicant shall submit a revised landscape plan showing the minimum number of landscape islands/peninsulas and trees. Additionally, screening for parking along Lake Drive is not adequate. The applicant can match the existing screening or revise the selected shrubs to a species with greater height The landscape island on the north end of the parking proposed adjacent to the east side of the building shall be extended further out to provide full protection of the parking space immediately adjacent to the island. MISCELLANEOUS Building The propose number of accessible parking spaces (7) with adjacent access aisles and their locations are in accordance with Minnesota State Building Code (Chap. 1341, Accessibility). The plans and drainage calculations must be signed by a professional engineer licensed in the State of Minnesota. OTHER AGENCY APPROVALS The applicant will be responsible for applying for and procuring any additional permits that may be required for this project. It appears that all phases of this project exceed one acre of disturbance. If this is the case a National Pollution Discharge Elimination System construction stormwater permit will be required. COMPLIANCE REVIEW Required Parking Setback: North — 0', East— 0', South — 251, West— 30' Proposed Parking Setback: North — 60', East — 20', South — 25', West — 35' Parking Standards: Manufacturing or processing plant — One off-street parking space for each employee on the major shift and one off-street parking space for each motor vehicle when customarily kept on the premises.

All voted in favor and the motion carried unanimously with a vote of 5to0. Josh Koller: Thanks for your time. Mayor Furlong: Yep, thank you. Move now to the next item on our agenda which is the Lake Drive Business Center, a request for a site plan review of 155 stall parking lot expansion at 950 Lake Drive. Staff report. LAKE DRIVE BUSINESS CENTER: REOUEST FOR SITE PLAN REVIEW FOR A 155-STALL PARKING LOT EXPANSION. 950 LAKE DRIVE. APPLICANT: CSM CORPORATION. Kate Aanenson: Thank you Mayor. As you stated this request is for a parking stall expansion for the Lake Drive Business Center. It's located just at the Highway 5 and the current zoning on that is industrial office park. To the east you've got Robert's Automotive. You've got the Lake Susan Business Park. To the west it's vacant industrial land. We did receive one comment from, off of the Powers Boulevard property just immediately to the west. They had some concerns about the visibility of grading. Although that property isn't developed, the grades on that are such that I'm not sure they would see a lot of it so, we did send them back our comment that it did meet ordinance. There's no variances requested with this. It does meet ordinance so the parking lot expansion's really to accommodate some additional parking on the southwest, 48 additional stalls. On the southeast, 41 additional spaces and then on the east 66. So this could be done in phases. The real goal here is to accommodate the ability for the property owner to sell this property and make sure that the user needs additional parking, the plan's been approved so they can say that there's already entitlement to the property and they could go ahead and proceed with the parking lot so it provides them the flexibility to a potential buyer. So the grading plan itself does have some retaining walls with it. On the southwest side it's about 2 1/2 feet. On the southeast side it's about, almost 7 feet. And the east side's the tallest. The 8 feet and there's a tall one on the north side which would be about 17 feet so there is one issue on the drainage and utility easement on this side. There's the drainage, excuse me the retaining wall goes into the drainage utility easement. That needs to be moved. That may reduce some of the parking stalls there but I think we can accommodate that. Or the applicant can so when they come in for a final plans then they would have to accommodate that. And then there's also an existing stairwell that they need to accommodate through that retaining wall. They've also submitted a landscape plan and there's a few deficiencies in that but again we believe that can all be accommodated. Again this plan may not go forward immediately. It just depends on the currently they want to maximize the lease space in there so it does provide them the flexibility. The Planning Commission at their meeting did recommend approval of this plan when they had their meeting on August 16"' they voted 6 for, none against recommending the parking lot expansion and with that the motion we have for you would then also to approve the site plan for the parking lot expansion. With the condition in the staff report and with that I'd answer any questions that you have. Mayor Furlong: Thank you. Any questions for staff? Any concerns from the property to the east? Kate Aanenson: Yeah we did talk, we did talk to them. Mayor Furlong: Okay. Kate Aanenson: They live out of state. We did let them know that all the requests did meet code. There is additional landscaping that would be put in there and I think that was some of the concern that they would look and see a lot of landscaping. I mean it was a lot of parking but actually the landscape would buffer that so I think we've accomplished that and we. 32 SCANNED Chanhassen City Council — September 12, 2011 Mayor Furlong: Is this, I'm sorry, is this the property to the west across Powers that you're talking about or to the Robert's Automotive to the east? Kate Aanenson: Yeah, it's actually the piece across on Powers Boulevard. Mayor Furlong: Right. They expressed some concerns. Kate Aanenson: Yep, nobody else commented on it. Mayor Furlong: Okay. Kate Aanenson: Yes, I'm sorry. Mayor Furlong: Alright, thank you. Any other questions for staff? Comments, thoughts. I mean it's within, it meets ordinance. It's, there's no variances required. People are looking to improve the property. Kate Aanenson: It gives them the flexibility to maximize the building which is what we would like, yes. Mayor Furlong: Absolutely. Councilman Laufenburger: Is the building vacant right now Kate? John Ferrier: It's largely vacant. Kate Aanenson: Yes. Mayor Furlong: Okay. Any comments from the applicant they'd like to share with the council this evening? John Feiner: Good evening Mayor and council members. I'm John Ferrier with CSM Corporation. I represent the owner. Also here with me tonight is Mark Kronbeck. He is the engineer that worked on the plans and first I'd like to thank staff for working with us on this request. Essentially you said it, we just want to make the building more marketable. Not necessarily for a sale but we like our buildings to have tenants and so this one's been largely vacant for some time so we're looking at ways, creative ways to bring in more tenants so. We've read the staff report and agree with it's findings so we're here to answer any questions. Thank you. Mayor Furlong: Thank you, any questions for the applicant? Thank you. Councilman Laufenburger: Yeah I do have, John. John Ferrier: Yes. Councilman Laufenburger: Mr. Ferrier. Is it, is the inside of the building designed for industrial or office or what? John Ferrier: It is, it's one part of the property which is the property to the west was largely office so if you see in the lower left hand comer of the plan where that black paving area is. Councilman Laufenburger: Okay 33 Chanhassen City Council — September 12, 2011 John Ferrier: That's where a lot of the parking we're bringing in. That's probably what we would do first because with, to the west with that large office component, there just isn't enough parking for the office component. The two areas more to the east are more of your standard office or standard warehouse with a little bit of office component. Councilman Laufenburger: Is there access to the buildings? Are there doors on the southeast and the east side? John Ferrier: Yes. Councilman Laufenburger: Okay. Yeah, I like it Mr. Mayor. Mayor Furlong: Okay, thank you. Any other comments? Discussion. If not, would somebody like to make a motion? Councilwoman Ernst: I will. Mayor Furlong: Councilwoman Ernst. Councilwoman Ernst: 1 make a motion we approve the site plan for parking lot expansion located at 950 Lake Drive, plans prepared by Alliant Engineering, Incorporated dated July 19, 2011, subject to the conditions of the staff report, and adoption of the Findings of Fact. Mayor Furlong: Thank you. Is there a second? Councilman Laufenburger: Second. Mayor Furlong: Thank you. Is there any discussion on the motion? Sometimes the easy ones are hard to get the second on. If there is no discussion, we'll proceed with the vote.

APPLICANT: CSM CORPORATION. PLANNING CASE 2011-08. Public Present: Name Address John Ferrier, CSM Corporation 500 Washington Avenue So, Minneapolis Mark Kronbeck, Alliant Engineering 233 Park Avenue So, Minneapolis Generous: Thank you Chairman Aller, commissioners. As you stated this is a public hearing to review proposed parking lot expansion. The applicant made this application because they wanted additional flexibility and marketability on the property. Currently the site is mostly, mainly vacant. The building is and so they're looking for tenants to accommodate them in the future. The site plan review request is for 155 stall parking lot expansion. They're proposing it in three locations on the site and that would mostly occur in three phases. They're going through the site plan review process because the grading on, for the proposal is a little more than staff could approve administratively. Additionally we're reviewing the grading, the lighting, a sign relocation and the landscaping in conjunction with the parking lot. This property is zoned industrial office park. It's located on the northeast corner of Lake Drive and Powers Boulevard. To the east of it is Robert's Automatic. To the south is Lake Susan or Lake Susan Park. It's a community park. To the west is a vacant industrial office park site and I did hand out an email I received yesterday. The property owners have concern that when they develop their site, coming down their driveway they will see a parking lot in the comer. However I did respond to them and advised them that the parking lot is a permitted accessory use in the IOP district. That their proposal complies with all the zoning requirements and that we will as part of our review require that they provide landscaping around it so I haven't heard anything back from him but I told him that I'd give it to the Planning Commission and put it on the record. SCANNED Chanhassen Planning Commission - August 16, 2011 Alley: Okay just for the record we have received that and it should be made part of the Minutes so thank you. Generous: And then finally on the north side of this is the railroad tracks and it's very high above this site so you can't actually see it from the north. As I said there's three locations that they're proposing parking expansion. On the southwest corner of the site, which is this area down here, they're proposing a total of 48 parking spaces. The southeast comer they're proposing 41 spaces and on the east side there is a total of 66 spaces. Again they're, they would develop this in phases with the first phase being the southwest parking area. However if they did have a big user come in I'm sure they'd put all the improvements in at one time. The applicant is here and he can expand on that. Basically this is a review of the grading plan. It should be pointed out their extensive retaining wall systems on that. The smallest one is located in the southwest parking area and it's highest point is 2 '/z feet tall. The second one is around the southeast side of the building and it's tallest point is 6.8 feet. On the east side, along this edge of the property they're proposing an 8 foot 8 foot tall retaining wall and then the final one in this truck turnaround area would be 17 %2 feet. The issues that we have with their proposal would be that on the east side of the property there's a 20 foot wide drainage and utility easement. That contains a large stormwater pipe and so we would require that they keep all the retaining wall improvements out of that easement. What this will force them to do is either push all the parking to the west adjacent to the building, if that's possible, or we looked at an alternative where they could get a row of parallel parking on this east side and that would reduce, because they're 8 foot wide stalls instead of the 18 foot deep so they could pick up 10 feet. Or they could just eliminate that parking in that area and leave it up to the applicant to figure out and their engineer what's their best alternative. The other issue that we talked about within the report is that depending on the usage of the building there may be some exiting requirements along the south side, specifically if they have office occupancy in the warehouse area they would need to provide additional egress from the building and that, we believe that they could handle that through the use of a stairway system down into the parking area but it would again it depends on the occupancy in the future so we just wanted to advise them upfront that that may become an issue depending on who they get for a tenant. And finally the landscaping plan, they are deficient in the number of landscape peninsulas that they have as part of their parking requirements. City code requires islands or peninsulas for every 6,000 square feet of vehicular use area. This was intended to help break up the large expanses of parking lot and so they will need to provide us with a revised plan showing how they're going to locate that, and then there was one other issue in this northeast comer of the parking lot. This last stall is not protected by the landscape island and so we would have them extend that out farther so vehicles coming around that corner won't clip the back of a vehicle parked in that stall. And then as far as landscaping, right now there's significant trees in this area of the site that will be reviewed once these, if this parking area goes in and so they need to provide additional landscaping, screening along that drive. With that staff is recommending approval of the site plan subject to the conditions of the staff report. And I'd be happy to answer any questions. Alley: Okay we'll start, Kevin if you have any. Ellsworth: Ah Mr. Chair yes, I do. On page 4 and 5, Bob we talk about stormwater management and down at the bottom, the fast full paragraph on page 5. While this system is generally 2 7 Chanhassen Planning Commission - August 16, 2011 acceptable it is undetermined at this time how it will be maintained. And so it, looking for an agreement on how it will be provided. I did not see that in the recommendation on the conditions and maybe I missed that and I guess I'm curious as to what that would encompass. Jeffery: Chairman Aller, Commissioner Ellsworth. I have had discussion with the applicant and with the applicant's engineer. Their standard maintenance and operation, operations and maintenance manuals that would go with it. It is a little tricky with the underground system as to how you get the sediment out of the void spaces. That will be, will need to be looked at as we move forward. At this time it was left fairly open ended so that we could have that discussion and decide how best to handle it. We do within our surface water management plan have generalized form that we, for private stormwater maintenance or private stormwater system maintenance and that would be provided to the applicant for, at a minimum a template of the minimum information that would be required. Ellsworth: So you're confident that there's enough capability in this system and adequate maintenance would be provided, that this would not turn into a go, no go situation? Jeffery: Yeah, that's correct. That is correct because at this time what we are really looking for is a more rate control with this system than treating. We do have the Lake Susan pond that will be providing the water quality treatment we're looking for. It's really because of the large watershed that goes through this system we need to make sure that we slow the water down leaving the site and don't increase rates on the site. Ellsworth: Who owns that Lake Susan pond and who's responsible for it's maintenance and dredging it when it fills up and so on? Jeffery: That is owned by the City of Chanhassen and we are responsible under MS4 permit for the maintenance of that, and I did bring it up in the report that perhaps in future phases there might be a more efficient way to spend their stormwater dollars over on that pond itself rather than trying to install another one of these system with future phases. That would be to be determined and if we had enough lead time to try and come up with a way to do that but really at this time we're primarily concerned with maintaining rates coming off of that site. Ellsworth: Okay, thanks Terry. That's all Mr. Chair Hokkanen: No questions. Not yet. Aller: Commissioner Doll. Doll: Just is there a view issue with that vacant lot? I'm just confused as to how that would affect their view of the park. Generous: Is there a view issue? Doll: With this email here about the. Chanhassen Planning Commission - August 16, 2011 Undestad: The Pauls property. Doll: The Pauls property. Aanenson: Can you go back to that trail. Doll: The view corridor, is that really an issue? Aanenson: When you look at that driveway coming up off of Powers Boulevard, it's actually fairly steep going up so really the view shed is on Powers Boulevard I think getting to and from the site and I think that's what Mr. Generous was saying. Is that we look at landscaping that or trying to replace that or put additional landscaping there but it does meet city code. The city code does say that you should land, screen parking in front of buildings so that's one of the conditions of approval is so, but they do have a right to do that just as long as they follow code, which will be the screening but yeah from the top of the site, no. It'd be very difficult to see that. Doll: I thought that site was higher on the other side. Aanenson: Significantly, yeah. It's just, I think it's just a view perspective coming in. Doll: Okay. That's it. Undestad: No questions. Aller: Ms. Tennyson? Tennyson: No questions. Aller: Okay, nothing from me at this point. We have an application that wants to come forward and make a presentation? John Ferrier: Good evening Chair and Commissioners. I'm John Ferrier with CSM Corporation. Also with me tonight is Mark Kronbeck. He is with Alliant Engineering and put together the engineering plans. We reviewed the staff report and we agree with his findings. You know this parking lot expansion is largely market driven. On the southwest portion of the site we have a dismissed office area that's 100% office. It is adjacent to some warehouse, however there's very little parking in front of that office area. We've had several tenants go through the space and say well we need more parking in the front of the, you know kind of the entry part of the office, so Phase I is definitely that kind of V shaped area that he's pointing to right there. The other areas that we're proposing parking will be dictated by the kind of tenants we have come through there. We didn't want to be encumbered by the fact that they say oh, we need more parking and then we say it'll require city approval. We wanted to get it approved all at once so we can at least show them an exhibit that shows all this parking. This building has been largely vacant since we purchased it so we're looking for all kinds of creative ideas to get it leased up which in turn helps us and in turn helps you as well so we think that it's a great project. We appreciate the help from Chanhassen Planning Commission - August 16, 2011 staff and we'll work with staff to work through some of these issues as part of the recommendation so, if you have any other questions I'm here to answer any questions. Aller: I just want to confirm that what I'm hearing from you is you've read the report. You agree with all the conditions that are in the report? John Ferrier: Yes. Aller: And you understand that the, that primarily that easement in that area has to stay pretty much clear based on the conditions here concerning that water flow. John Ferrier: Correct. And I was talking with our engineer prior to the meeting. He has some ideas to keep some of that parking and adhere to the easement so. Aller: And then there were other conditions in here regarding the pollution discharge permits and things like that. John Ferrier: Right. Aller: You understand that we want those before Phase I. John Ferrier: Absolutely, yep. Aller: Okay. Any other questions? Great, thank you very much Mr. Ferrier. Okay we'll open the public hearing. Anyone that wants to speak on the matter, please come forward. State your name, address for the record. Seeing no one come forward, I'm going to close the public hearing. Comments from commissioners. Tom, anything? Doll: No. Undestad: No, looks good. Ellsworth: Looks like a good project. Aller: I think it's a good project. I like the fact that you looked at the entire plan even though it may be done in phases. That we get a foreshadowing of what's coming forward so, and the conditions are certainly reasonable. I think it's a good plan. Do I hear a motion? Undestad: I'll make a motion. Aller: Thank you Commissioner Undestad. Undestad: That the Chanhassen Planning Commission recommends the City Council approve the site plan for parking lot expansion located at 950 Lake Drive, plans prepared by Alliant Engineering dated July 19, 2011, subject to the conditions of the staff report and adoption of the Findings of Fact and Recommendation. Chanhassen Planning Commission - August 16, 2011 Aller: Can I have a second? Doll: I'll second. Alley: Commissioner Doll seconds. We have a motion and a second. Any further discussion? Undestad moved, Doll seconded that the Planning Commission recommends the City Council approve the site plan for parking lot expansion located at 950 Lake Drive, plans prepared by Alliant Engineering dated July 19, 2011, subject to the conditions of the staff report and adoption of the Findings of Fact and Recommendation: Plannin¢ Department Conditions 1.

APPROVAL OF MINUTES: Commissioner Ellsworth noted the verbatim and summary minutes of the Planning Commission meeting dated July 19, 2011 as presented. COMMISSION PRESENTATIONS: None. CITY COUNCIL ACTION UPDATE: Aanenson: Yes, on Monday, August 8`h the City Council approved the Bluff Creek 40' Addition, and you don't usually see the final plats. You see the preliminary so some of you may not be aware but that would be 19 additional lots with that so, that area is actually pulling a lot of permits. Hokkanen: And they're selling. Aanenson: Yes they're selling out there and the old Pioneer Pass yep, so they're doing well up there. And then I just wanted to note too that the City Council did table the paintball shooting courses but we've addressed some of their issues so actually the shooting range will be back on next Monday. There's a couple other action items they had to take so most of that meeting will be dedicated to budget but they will hear, we separated the paintball and shooting and actually it was helpful because the City Attorney also just recently, in Lakeville they had a Gaylan's that has shooting range so we had some of our specific questions addressed and added some additional comments so you, anything that would be requested would come back before you under a conditional use permit so we felt comfortable, the staff did with those changes and just i CITY OF CHANHASSEN P 0 BOX 147 CHANHASSEN MN 55317 08/16/2011 10:55 Receipt No. 00164237 CLERK: bethanym PAYEE: John Ferrier 4637 Oakland Ave Minneapolis MN 55407- Planning Case # 2011-08 ------------------------------------------------------- Property Owners List 15.00 Total 15.00 Cash 0.00 Check 4166 15.00 Change 0.00 ec"Wo 7700 Market Boulevard PO Box 147 Chanhassen, MN 55317 MEMORANDUM TO: Bob Generous, Senior Planner FROM: Terry Jeffery, Water Resources Coordinator \R DATE: August 8, 2011 Administration Phone: 952.227.1100 RE: Lake Drive Business Center Fax:952.227.1110 Building Inspections Phone:952.227.1180 PROJECT UNDERSTANDING Fax:952,227.1190 I have reviewed the plan set for the Lake Drive Business Center prepared by Alliant Engineering Engineering and dated July 19, 2011.

Based upon my Phone: 952.227.1140 review of these materials I have the following comments and conditions: Fax:952.227.1110 The applicant is proposing to construct 155 new parking stalls in three areas. These Park & Recreation parking areas are to be phased in with only the most southwesterly parking area being Phone: 952.227.1120 constructed with the first phase. The applicant is proposing to utilize perforated Fax: 952.227.1110 storm sewer and embedded within a rock trench to achieve rate control and some pre - Recreation Center treatment of the runoff. 2310 Coulter Boulevard Phone: 952.227.1400 SURFACE WATER DRAINAGE Fax:952.227.1404 Water from this site is directed to Lake Susan pond (LS-P3.34). Approximately 150 Planning 8 Natural Resources acres of commercial and industrial land use is also directed to the Lake Susan Pond. Phone: 952.227.1130 This water is routed through three primary storm sewer conveyance routes. Powers Fax: 952.2271110 Avenue from MN T.H. 5 to Lake Drive is routed through a 30 inch RCP along Powers Boulevard. Chanhassen Retail Addition is routed through a 36 inch RCP Public Works immediately east of the subject property.

Because of the existing infrastructure and size of the contributing watershed, rate control must be achieved on site. However, the City would still have an interest in partnering with the applicant and other agencies to implement some alternative storm water BMPs. WETLANDS AND SHORELAND No wetlands appear to exist on or immediately adjacent to the proposed project area. Although the subject property is tributary to both Lake Susan and Riley Creek it lies outside of the shoreland overlay district for both of these water bodies. EROSION AND SEDIMENT CONTROL The applicant has prepared an erosion control plan for all phases of this project. The first phase of this project will result in 3:1 slopes with a positive grade towards Lake Drive. This disturbed area will need to be covered with erosion control blanket or sod within 14 days of cessation of work. This should be indicated in the plan. Other than the need for blanket or sod on all 3:1 slopes, the plan appears adequate for existing conditions. However, a note must be added to the plan that additional best management practices may be necessary as site and climatic conditions change throughout construction. To assure that erosion and sediment control best management practices are installed and maintained an escrow or letter of credit in the amount of $2,450 will be required with the first phase. This number was calculated based upon 450 feet of silt fence, three (3) inlet protection devices, and 370 yards of blanket and seed. OTHER AGENCYAPPROVALS The applicant will be responsible for applying for and procuring any additional permits that may be required for this project. It appears that all phases of this project exceed one acre of disturbance. If this is the case a National Pollution Discharge Elimination System construction stormwater permit will be required. CONDITIONS OF APPROVAL 1. Rates of surface water runoff must not be increased from existing conditions. Where practicable to do so, rates should be decreased. 2. The applicant and City shall work together on future phases to look for potential cooperative surface water management opportunities. 3. These approvals for future phases are contingent upon City Code and other jurisdictional agency rules remaining the same. In the event that any of these rules change, the applicant will need to resubmit to assure that the plans meet any new rules germane to this project. 4. Include a note on the Grading and Erosion Control plan indicating that the proposed best management practices is the minimum controls anticipated but that as unanticipated site and climatic conditions present themselves, it will be to modify the best management practices to meet these new conditions. 5. All 3:1 slopes shall be covered with erosion control blanket or sod. This needs to be indicated within the plan set on sheet C-2: Grading and Erosion Control. 6. An escrow or letter of credit in the amount of $2,450.00 shall be provided to the City before commencement of the first phase. This escrow is only for the first phase. Subsequent phases will require additional assurance funds. 7. Applicant must apply for and receive approvals from other jurisdictional agencies as necessary. 8. The applicant must show that the total disturbed area for all phases is less than 1 acre or the must apply for and receive an NPDES Construction Stormwater Permit from the MPCA. If this is the case, a full Surface Water Pollution Prevention Plan must be prepared and submitted to the City for review and comment. 9. All exposed soils must be stabilized with 14 days of cessation of earthwork activities. 10. Lake Drive must be swept clean of soils and debris tracked onto it from the site as needed but no less than once per week until final stabilization is achieved. 11. The applicant or their designee must maintain the best management practices in good working order until final stabilization is achieved. This concludes my review.

A 188,900 sq. ft. building with parking is currently on the site. Beyond the parking and building areas is grass. This development is located in the Bluff Creek Watershed District. Grading will take place on the site to prepare the parking areas. The grass area maximum slope must not exceed 3:1. Runoff from this site will be treated using an underground treatment system. The drainage and storm sewer system within the site is privately owned and must be maintained by the owner. Existing runoff rates must be maintained for the 2-, 10- and 100-year rain events. The drainage calculations do not match the plans. The applicant must submit revised plans and calculations meeting City requirements. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. RETAINING WALLS The proposed retaining walls are as follows: Location Length Maximum (approx.) Height (approx.) Southeast comer parking area I all 1 70 feet 2.5 feet North side of parking area 2 — 5' from the 430 feet 6.8 feet building (Wall 2) East side of parking area 3 (Wall 3) 360 feet 8.8 feet North side of parking area 4 (Wall 4) 330 feet 17.5 feet Chanhassen is a Community for Life . Providing for Today and Planning for Tomorrow Robert Generous Lake Drive Business Center Site Plan Review August 16, 2011 Page 2 of 3 Building permits are required for all retaining walls four feet tall or higher and must be designed by a Structural Engineer registered in the State of Minnesota. The exits in front of Wall 2 may be inadequate for some uses of the building under the proposed parking scenario. Exterior exit discharge must accommodate exits served. The parking stalls in this area should be constructed at the time when a final end user is determined so that the exits will not limit the occupancy. The wall and support structure (not including soil) in Parking Area 3 must be moved outside of the City utility easement. A 36" diameter storm sewer is within this easement. Moving the wall in this area will cause a reduction in the number of parking stalls. UTILITIES Details must be provided for all proposed storm, sanitary, and watermain crossings. Actual elevations of existing utilities shall be verified for accuracy. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to provide the City with the necessary financial security in the form of a letter of credit or cash escrow to guarantee the installation of the storm sewer, erosion control, and seeding. This amount will be determined prior to start of construction due to the possible phasing of the project and not knowing the amount to be installed and disturbed. The applicant must also notify the City after installation of the erosion control and 48 hours prior to the commencement of grading. Permits from the appropriate regulatory agencies will be required. MISCELLANEOUS The plans and drainage calculations must be signed by a professional engineer licensed in the State of Minnesota. RECOMMENDED CONDITIONS OF APPROVAL 1. Grass area maximum slope must not exceed 3:1. 2. The applicant must submit revised plans (redlines) which meet the requirements of the City. 3. Drainage plans must be revised so that the plans match the drainage calculations. The applicant must also follow City standards for water quality volume. Also, the proposed drainage rates must be maintained for the 2-, 10-, and 100-year rain events. 4. The storm sewer provided for treatment will be privately owned and maintained. 5. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. g1eng\site plansVake drive business center%8-16-11 spr.dmx Robert Generous Lake Drive Business Center Site Plan Review August 16, 2011 Page 3 of 3 6.

The plan set consisted of nine (9) sheets. City staff Engineering met with representatives from Alliant Engineering, Inc., the applicant's consulting Phone:952.227.1160 engineer, on July 25, 2011. Updated sheets 5-C-2 and 6-C-3 and the HydroCAD Fax:952.22T1170 summary were transmitted via email on July 28, 2011. Based upon my review of these materials I have the following comments and conditions. Finance Phone:952.227.1140 The applicant is proposing to construct 155 new parking stalls in three areas. These Fax:952.227.1110 parking areas are to be phased in with only the most southwesterly parking area being Park & Recreation constructed with the first phase. The applicant is proposing to utilize perforated storm Phone:952.227.1120 sewer and embedded within a rock trench to achieve rate control and some pre- Fax:952.227.1110 treatment of the runoff. Recreation Center SURFACE WATER DRAINAGE 2310 Coulter Boulevard Phone:952.227.1400 Water from this site is directed to Lake Susan pond (LS-P3.34). Approximately 150 acres Fax:952.227.1404 of commercial and industrial land use is also directed to the Lake Susan Pond. This Planning & water is routed through three primary storm sewer conveyance routes. Powers Avenue Natural Resources from MN T.H. 5 to Lake Drive is routed through a 30 inch RCP along Powers Boulevard. Phone:952.227.1130 Chanhassen Retail Addition is routed through a 36 inch RCP immediately east of the Fax:952.227.1110 subject property. The third area drains through a 30 inch RCP along Lake Drive and accepts drainage from Lake Drive as well as the intersection of T.H. 5 and MN T.H. 101. Public Works Because of the size of the drainage area being conveyed through these pipes the 7901 Park Place applicant must either model the entire watershed to show that there is adequate Phone:952.227.1300 capacity in the pipes or maintain, or preferably decrease discharge rates to the system. Fax:952,227.1310 Senior Center While this system is generally acceptable, it is undetermined at this time how it will be Phone:952.227.1125 maintained. The City has required, and the consulting engineer has agreed to provide, a Fax:952.227.1110 long term operations and maintenance plan for this system. This system will remain private and the land owner will be responsible for the maintenance of the system. Web Site www.ci.chanhassen.mn.us With proper lead time, staff has indicated to the applicant's engineer that the City would have an interest in working with the applicant to procure grant funds and partner Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow or accept cash in lieu of installation of the pretreatment features being proposed. Because of the existing infrastructure and size of the contributing watershed, rate control must be achieved on site. However, the City would still have an interest in partnering with the applicant and other agencies to implement some alternative storm water BMPs. WETLANDS AND SHORELAND No wetlands appear to exist on or immediately adjacent to the proposed project area. Although the subject property is tributary to both Lake Susan and Riley Creek it lies outside of the shoreland overlay district for both of these water bodies. EROSION AND SEDIMENT CONTROL The applicant has prepared an erosion control plan for all phases of this project. The first phase of this project will result in 3:1 slopes with a positive grade towards Lake Drive. This disturbed area will need to be covered with erosion control blanket or sod within 14 days of cessation of work. This should be indicated in the plan. Other than the need for blanket or sod on all 3:1 slopes, the plan appears adequate for existing conditions. However, a note must be added to the plan that additional best management practices may be necessary as site and climatic conditions change throughout construction. To assure that erosion and sediment control best management practices are installed and maintained an escrow or letter of credit in the amount of $2,450 will be required with the first phase. This number was calculated based upon 450 feet of silt fence, three (3) inlet protection devices, and 370 yards of blanket and seed. OTHER AGENCY APPROVALS The applicant will be responsible for applying for and procuring any additional permits that may be required for this project. It appears that all phases of this project exceed 1 acre of disturbance. If this is the case a National Pollution Discharge Elimination System construction stormwater permit will be required. CONDITIONS OF APPROVAL 1. Rates of surface water runoff must not be increased from existing conditions. Where practicable to do so, rates should be decreased. 2. The applicant and city shall work together on future phases to look for potential cooperative surface water management opportunities. 3. These approvals for future phases are contingent upon City code and other jurisdictional agency rules remaining the same. In the event that any of these change the applicant will need to resubmit to assure that the plans meet any new rules germane to this project. 4. Include a note on the Grading and Erosion Control indicating that the proposed best management practices is the minimum controls anticipated but that as unanticipated site and climatic conditions present themselves, it will be to modify the best management practices to meet these new conditions. 5. All 3:1 slopes shall be covered with erosion control blanket or sod. This needs to be indicated within the plan set on sheet C-2: Grading and Erosion Control. 6. An escrow or letter of credit in the amount of $2,450.00 shall be provided to the City before commencement of the first phase. This escrow is only for the first phase. Subsequent phases will require additional assurance funds. 7. Applicant must apply for and receive approvals from other jurisdictional agencies as necessary. 8. The applicant must show that the total disturbed area for all phases is less than 1 acre or the must apply for and receive an NPDES Construction Stormwater Permit from the MPCA. If this is the case, a full Surface Water Pollution Prevention Plan must be prepared and submitted to the City for review and comment. 9. All exposed soils must be stabilized with 14 days of cessation of earth work activities. 10. Lake Drive must be swept clean of soils and debris tracked onto it from the site as needed but no less than once per week until final stabilization is achieved. 11. The applicant or their designee must maintain the best management practices in good working order until final stabilization is achieved. This concludes my review.

We are concerned about the addition of 150 parking spaces being added to this lot. Our primary concern is with the spaces located at the intersection of Powers and Lake Drive. These will fall directly in the view corridor from our lot to Lake Susan Park. We have no problems with any of the other lot expansions. Since our intersection is already built we will have to build a road north east from that intersection parallel to Powers Dr to access our lot (as seen on PID map attached). When leaving our lot you will look right at those new parking spaces as you drive down to the intersection from our build -able area. Please include this in the meeting minutes. If you have any questions please call Scoff or Glenn at 970-728-3540 970-318-6614 Thanks Non -Scannable Item Item Description 'Oolder Number Folder Name 06 1-� A � Job Number 3 Z 2-�, - Box Number Z mem::orex- CD MR /� 4 G�iprt vL/ 1/(ilT uGf3 CG+7""
