PC Minutes 07-16-2013Chanhassen Planning Commission – July 16, 2013 Aller: I have a motion. Do I have a second? Yusuf: Second. Aller: Any further discussion? I’ll just say I believe that there are other variances that have been granted in that area that this would be in line with as stated in the report. Hokkanen moved, Yusuf seconded that the Planning Commission, as the Board of Appeals and Adjustments, approves a 5.8% hard cover variance to permit the construction of a single-family home subject to the following conditions and adoption of the attached Findings of Fact and Decision: 1. The builder shall provide a tree survey as part of the building permit process. The builder shall try to preserve the trees at the perimeter of the property. 2. The building shall be limited to the split level house design. 3. The builder shall apply for a building permit and meet all requirements of said permit. All voted in favor and the motion carried unanimously with a vote of 4 to 0. PUBLIC HEARING: BLUFF CREEK COTTAGES: REQUEST TO REZONE 8.9 ACRES OF PROPERTY FROM AGRICULTURAL ESTATE DISTRICT (A-2) TO MIXED MEDIUM DENSITY RESIDENTIAL DISTRICT (R-8); SITE PLAN REVIEW WITH VARIANCES FOR THE CONSTRUCTION OF A SENIOR HOUSING FACILITY; AND A CONDITIONAL USE PERMIT TO ALLOW DEVELOPMENT WITHIN THE BLUFF CREEK OVERLAY DISTRICT. PROPERTY IS LOCATED NORTH OF PIONEER TRAIL AND WEST OF BLUFF CREEK BOULEVARD. APPLICANT: CHESTNUT GROUP, LLC. OWNER: JOHN KLINGELHUTZ, PLANNING CASE 2013-08. Al-Jaff: Good evening Chairman Aller, members of the Planning Commission. The application is for a senior housing project, extended care. The site is located north of Pioneer Trail, west of Bluff Creek Boulevard. The existing zoning as well as the land use on the site, the 2030 Land Use Plan shows this area designed for development as medium density. Medium density allows for 4 to 8 units per acre. Types of development appropriate zoning for this type of land use would be an R-8, an RLM which allows for mixed types of low medium density or a planned unit development residential type of zoning. What the applicant is proposing to develop on this site is a single building which will contain 24 rooms. Individual rooms. The occupants of the building will be individuals that need assistance with their mobility. They will put a substantially less demand on the infrastructure of, on the infrastructure than a typical medium density type of development would. And for a continuing care facility the only type of zoning that is, that allows this type of use within the city is the R-8, which is the medium density. So with that said, what the applicant is requesting is a rezoning of the property from currently as I said it is zoned Agricultural Estate District. They are proposing to rezone it from Agricultural Estate to Medium Density which is R-8. They are also requesting a site plan approval for the construction of a continuing care retirement facility and a conditional use permit since the site falls within the Bluff Creek Overlay District. The only way you are allowed to develop within that area is if the City grants a conditional use. The current zoning of the site is Agricultural Estate District. The applicant is requesting they rezone it to Medium Density. That type of rezoning is consistent with the Land Use Plan and staff is recommending approval of this rezoning. It is compatible with the surrounding area. The area to the north of it has a medium density. The area to the east has 4 units per acre and then as we go into the Chaska portion of the 7 Chanhassen Planning Commission – July 16, 2013 city, which is to the southwest, that area is all residential single family homes. The site plan basically consists of a building that will gain access off of Pioneer Trail. Bluff Creek runs along the northeast portion of the site. The total area of this building is 13,700 square feet. As I mentioned earlier it will be one story. 24 bedrooms within this building. The maximum hard surface coverage permitted under this district is 35%. What the applicant is proposing will result in 8.9% hard surface so they are substantially below the maximum permitted. One of the things that the applicant has done with this building is extended a sidewalk that basically goes along the driveway and it will connect with a regional trail along Pioneer Trail. The design of the building is attractive. It is proposed to be constructed of high quality materials. They include a cultured stone and a sample of the materials is available. There will also be paneling. All elevations that can be viewed from the public, by the public have been treated equal. Treated and given equal attention. There is variation throughout the building and the windows, as well as doors will comprise over 50% of each elevation as required by ordinance. Bluff Creek. As mentioned earlier Bluff Creek runs along the northern portion of the site. The area that is highlighted in red on this slider shows the secondary zone while the blue is the primary zone on the site. Staff has had conversations with the developer and it is the applicant’s intention to ultimately donate this property to the City. The required 40 foot setbacks from Bluff Creek primary zone are being met. Of that 20 feet is going to be a buffer. And they have no intention of developing anywhere within the area that is the primary nor the secondary zone. So staff is recommending approval of the rezoning, the site plan approval and the conditional use permit to allow for the construction of this building for continuing care for the elderly and I’ll be happy to answer any questions. Aller: Great, thank you. And the report, as you noted, there’s a number of additional pages other than what has been presented in the viewing screen for the general public and can be found on the website. There are a number of conditions. Have you discussed the conditions with the applicant? And are they, and do they appear to be willing to comply with those? Al-Jaff: That’s for the next item. Aller: Oh, I’m sorry. Do we have an equivalent between, with the shrubs that were requested and the existing vegetation, do we know what that is? Al-Jaff: Yes. It is. Aller: In that buffer. Al-Jaff: They are working with the landscape. They’re working on the landscaping with the City Forester and when she reviewed the plans she indicated that they meet all the requirements. She had no additional comments nor conditions to add to this. Aller: That’s all I have for now so, any questions? Comments? Withrow: What is the size of the amount of land donated to the City? Al-Jaff: They are working with the Water Resources Coordinator and that will be something that will come in the future. There are some steep grades on the site. Some bluffs as well as wetlands. They could do it either through a subdivision or they could grant the City an easement to, over these wetlands and storm ponds. Withrow: Okay, and then in the report you mentioned that we’re still waiting on soil borings. Al-Jaff: Correct. 8 Chanhassen Planning Commission – July 16, 2013 Withrow: And I don’t know a whole lot about those but what is the likelihood that they won’t come back positive? And if so what would be done about it? What effect would that have? Al-Jaff: They will have to correct the soils. Withrow: They can remediate it? Al-Jaff: Correct. Withrow: Okay. Thank you. Aller: And if we pass this then any remediation would have to comply with the Bluff Creek requirements. Al-Jaff: Correct, as well as wetland setbacks, as well as the bluffs. Aller: And then was there a permit required then for the construction? No? Aanenson: Well no getting, I mean Chair, the process would be then for the, it’s not a subdivision so we put together a site plan agreement. There would still be security put in place for any public utilities or any landscaping that was to be put in place. The site plan would administer all that so then also for the building permit process…would be executed to find out if soil corrections…send it to a building official. And I just want to add one other, going back to, if I may go back to the site showing that watershed area. The donation. I’m just trying to find it on this. Oops, there it is. So if you look at this larger area, that’s what Sharmeen had indicated relief at, there’s some steep slopes and there’s some areas that…it’s topographically isolated so it really has no building utility…that’s fine, we can manage that so…because they’re not platting it right now and it’s not needed for any…except for the fact that they’re grading next to it…if they want to work through some other things with the City, that could be a separate discussion… Aller: Thanks for the clarification. Anything else? Alright, would the applicant like to come forward? State your name and address for the record sir. Dave Pokorney: My name is Dave Pokorney. I’m with Community Asset Development Group. My address is 1403 Valley View Road, Chaska. Thank you. So I actually don’t have a lot of comments. I think we spent a lot of time with the staff working through this. I’ve got to tell you I’m really glad I’m here with this project and not some of the other ones we looked at because the landowner has owned the land for a while. We looked at some different uses. I mean you can imagine if we had the townhouse project and we were really having to be up against the buffers and bluffs and that’s what, when we kind of hit upon this is the concept. We just said this is a really good use for the site. Quite frankly we’re not, as Sharmeen’s indicated we kept away from all of the bluffs. Were able to, there are a few trees on one corner that we’re touching but everything else is staying so for us it’s, we’re excited about the project because we think it’s a really good use but quite frankly we’re also excited it was not a difficult process to develop this site. I mean we’ve known for some time that this was going to be a challenge. Relative to the dedication, I think our discussion we’ve been having with the staff is that basically everything that you see that’s outside of the red line and this we would deed either an easement. It probably would be an easement because we are not going through a platting but it really is a piece that should be public. Should be preserved. People should have the right to go in there. It has really little value once we develop this to our property, although it has the same value to us as it does to the rest of the public so we may have, we won’t have our residents hopefully that are using but we may have visitors that will use it as an open space. 9 Chanhassen Planning Commission – July 16, 2013 Aller: Just to make it clear. Dave Pokorney: …we’re happy with, relative to the conditions which I know is the next item, I do have to say I think it’s the most conditions I’ve ever seen in a project in a long time, if ever but we don’t have any concerns regarding the conditions. Aller: Well and I’m sure citizens are glad to hear we’re putting requirements out there. Obviously the dedication portion is not a requirement for purposes of moving forward with your project, nor is it something other than a general interest for the people out there listening. Dave Pokorney: And quite frankly the landowner will probably, because it’s not a requirement he’ll be able to get some kind of tax advantage that will work for him. Aller: So tell us a little bit more about the project itself. It’s a senior’s home. Tell us what you’re constructing. Dave Pokorney: Yep, so it’s a 24 unit building. It’s geared to seniors that have, either they’re having memory care issues or they’re elderly and very few, I mean we won’t have residents that have cars, put it that way. The way that it’s set up it’s actually two separate units. Living units. Both units on each side. Each living unit will have it’s own dining, living room area. We will join, the reason we put it into two 12’s, particularly with people who have memory care issues. The smaller and simpler that you can make them, it’s just a better environment but when we can combine them together then we have the joint staffing so in the evening times we don’t need, we can have one person staffing a 24 unit. During the day there’s more. These tend to be really that one story environment works well for seniors that have these types of issues. We’re, if there’s a down side to the site it’s a little bit remote but from an up side it’s in a really great environment and it’s a place that you know I’d like to sit out in the back porch and that’s what our residents will do so they can take advantage of the environment that’s there and it’s not the most convenient but it’s a place that people who are visitors, they’re going to be able to know how to get there so being right on the county road is actually a positive. I’d tell you that I’m not so sure that we’ll ever use the sidewalk. At least none of our residents will but we’ll put a sidewalk in. So assuming that it gets approved, we do have financing in place and we would anticipate starting construction probably in September and it’s a 6 to 7 month timeframe. Aller: Questions? Hokkanen: No, I think it looks good. Withrow: Yeah I have a question. Will there be any patios or decks or anything on the outside for visitors and your residents to enjoy this setting, as you say? Dave Pokorney: Yes. Yes, so there is, there’s a small patio directly out the back and then there’s on the north end of the site there’s a larger open space walking area. It shows up on our site plan as a little curly pathway. That will be fenced and again it’s because some of our residents will have memory care issues but that’s there for, not only for residents but for residents and their guests. And that type of a space is really important to these because people, for example on a day like today, maybe it was a little bit too hot today but people, it’s really a calming environment for them to be in and so you need to have outdoors, and actually I think it’s a second part of it when you development these. You have to have a minimum amount of outdoor space. We probably exceed it by a fair amount. 10 Chanhassen Planning Commission – July 16, 2013 Aller: Thank you sir. Anyone else have questions? Okay, I’m going to open the public hearing. Anyone wishing to speak for or against the item before us please come forward. State your name and address for the record. Chris Hammer: My name’s Chris Hammer. Address 9688 Washington Boulevard. It’s the property directly to the north of the property in question. My only possible cause of concern is potential impact into the wooded area and Bluff Creek itself in the future. It’s an area that should be protected. Is the City preventing any future development into that because that would affect our home values directly to the north. We have a nice private space with the wooded area and the creek behind with all the wildlife. We’re worried about the value of our homes being impacted in the future because if something comes in, what’s going to happen next. Aller: Okay, anybody have an answer for that? Aanenson: Sure. Similar to what we did on Liberty at Bluff Creek which is where you live, we actually preserved all these trees and this is part of that same continuum of the Bluff Creek Overlay and it’s in that area because it probably has significant slopes and the creek goes through there so it’s, you can see the area that’s…right now is where they’re putting the building and… Chris Hammer: Okay. Aanenson: So we worked hard to try to find a use that would accommodate that as the applicant just stated so. Aller: Thank you sir. Anyone else wishing to come forward speaking for or against? Seeing no one come forward, close the public hearing. Comments, questions from the commissioners. Hokkanen: I think it’s a good use of the property. It’s a nice addition to the city. Audience: Sir, I think we have audience comments… Aller: Oh, come on. Move faster than ever. Colleen Kroll: Three months ago I talked with Sharmeen about the possibility, 3 months ago we got letters explaining what was going to be developed in that space. My property is the odd shaped one on the north and. Aller: And your name and address? Colleen Kroll: Oh I’m sorry. I’m Colleen Kroll, 2694 Shadow Wood Court. Aller: Thank you. Colleen Kroll: And like I said, I’m the property that is the odd shaped one. Short on the north and long on the south side. Our property runs right down to the pond. We have a nice woods to the north and I’m curious about how the donation would be if it would become open for trails and public parks and so forth or how that would be detonated with Mr. Klingelhutz donating a certain percentage of what he has, as well as many, many years ago the easement for Pioneer was to become a much larger road and so the property can’t, the State owns it at the time period for it’s beginning to expand. When they no longer choose to have that as a need, what is that going to look like, once we say it’s okay to put a building in, how does that affect future development? Will there be a second building? Will there be a, you know 11 Chanhassen Planning Commission – July 16, 2013 how do you limit the growth on it because it’s really not that big of a space. It’s a meadow. It has a deep, steep slope. The ravine that runs through the trees is quite steep. I know that when you own something and you can take down as many trees as you want but it will change that entire environment and wild turkeys and the deer and everything else we have so we have some questions about that. Also how the sewage is hooking up into the city of Chaska so, I will let the other guys to address that part but we need to know more what the future’s going to be because when they’re sitting out on their back patio, which is going to be great, they’re going to be watching my kids in my pool. It’s a direct way. It’s about 50 feet away so it’s not that, as well as the pond fluctuates in height and to know exactly, I understand that the City, and I don’t know if it was Chanhassen or Chaska, took the highest height. What the pond history has done but there’s no flags on the meadow right now. There’s no flags for us to even understand where this development’s going to be. How it’s going to implement us so we’re going off of that but the building’s not even put on it in relationship to our houses so it’s really kind of hard for us to imagine what’s going to happen so the new building. In March we had a building placed on the, plotted out but not on the new development pieces that we’ve seen so, it does affect us that way so that’s our part. Aller: Thank you. Aanenson: Mr. Chair, there is copies of the plat. I mean it’s all engineered. Well this, I mean they’re all in the packet so maybe we can get that to the residents as well. Aller: And it’s all available on the website as well. Aanenson: Yep, so you can go on the finished floor elevation and then you can find your finished floor elevation from your building survey and then you get an idea of what that would be. Aller: Okay. And then can we go, there was a view of the property. There you go that at least gives you an idea of where some of the landscaping looks like it’s potentially… Aanenson: Yeah, all the plants are in… We can go back to the other one. Maybe Sharmeen wants to talk. It’s not our intent to get into where the trees and the ravine are, we don’t think that’s buildable. When MnDOT vacates the right-of-way on that property there is potential for another building. Again this property is zoned medium density. There could have been a lot of townhouses in there. We worked really hard to try to find that transition between the single family in Chaska and the residents in Chanhassen that are guided also medium density so we thought this was really a good use. Much less units in there. Much less traffic in there plus they’re also lower profile buildings so. Aller: That’s the question I got as well as the fact that we’re getting incredibly low hardscape. Aanenson: Correct, if we can go back to, yeah. Aller: So that’s going to help. We give a little here and there on these variances all through the city. It’s nice to be able to keep some so that we can get some of that water flow through the. Aanenson: Yeah, I’m just trying to find the one that showed the, I guess for the right-of-way. So when MnDOT would vacate that right-of-way, the potential then for additional building would be you know somewhere in this area. Somewhere through here so, but we don’t know what that timeframe is going to be. Al-Jaff: And it would have to appear before the Planning Commission and a public hearing would be held so we would have to go through the entire process again. 12 Chanhassen Planning Commission – July 16, 2013 Aller: Yes sir. Come forward. Please state your name and address for the record. Jeff Kerfeld: My name is Jeff Kerfeld. I live at 2702 Shadow Wood Court in Chaska and so I am two doors to the north and west of the Kroll family so just wrap around that cul-de-sac just a little bit so. Couple questions I have I guess, we’d like to get a little more clarification as far as how the sewer’s going to be connected to our neighborhood. It’s my understanding that the utilities will not be provided by the City of Chanhassen but will be provided by the City of Chaska and directly across the road from us is a lift station and on a regular basis we have the City of Chaska coming out to do maintenance on that. Their truck is there you know several times. Sometimes several times a month and of course we are concerned about that because we had issues with flooding in our basements. Power goes out but more importantly you guys had an incident in Lake Susan about 3 years ago I think with a watermain break that forced raw sewage in people’s basements and I don’t think we’re in a position where, if there’s a failure or a fault as a result of how this utility connection is being made that we want to have that possibly circumstance come to play into this Shadow Wood neighborhood so can we get a little, if now’s the appropriate time to get a little clarification. Aller: Let me see what I can get for you. Jeff Kerfeld: Okay, that’s great. Aller: That’s your main issue? Anything else? Jeff Kerfeld: Yeah, the other part is, I’d be very curious as far as Colleen had mentioned, it’s a fairly steep hill. I mean our kids go sliding down it during the winter time and then you know there really is no crest per se. It kind of goes down off to the other side so I’d be very interested, I did see on the map a little bit as far as where it’s placed. It seems like it’s placed more towards the pond than this but I really question how much leveling of that land and how they can do some leveling without removing some of those big trees. You know we see wild turkey and deer and pheasants and you know wildlife continually through that area so that’s, you know that’s a major concern. Aller: Thank you. Jeff Kerfeld: Beyond that I would also be curious to know as far as what sort of lighting is going to be used with regards to the building. Right now we look out obviously at a dark field. We do have the neighborhood to the north but that’s all protected. My house looks to the north and I don’t ever see those townhouses in that area and everything so the hope obviously would be that any lighting would be below the building so that at nighttime we wouldn’t, we don’t want a Walmart parking lot I guess is what I’m saying sitting out there in the field across the pond from us and everything so that’s a concern. And then lastly runoff. The pond fluctuates immensely. I mean we’ve had, I’ve lived in my house for 22 years so I’ve been in the Shadow Wood neighborhood for 22 years and we did have one year when there was no water in the pond. Generally we have water and we use that as a hockey rink. Skating rink for the kids in the neighborhood. I’m the dad that goes out and takes the snow blower out and blows off the pond every year but that’s part of our recreation for the neighborhood and everything. We want to insure that that water flow, that natural watershed provides water for that area for, you know for our continual enjoyment and such so. Beyond that, that’s all I have. Aller: Thank you sir. Jeff Kerfeld: Thank you. Appreciate your time. Aller: You want to hit those? 13 Chanhassen Planning Commission – July 16, 2013 Fauske: I would love to answer the questions. Aller: Thank you. Fauske: Is this on now? Okay. The question about the sewer connection, City staff has met with the City Engineer and the Utility Superintendent from the City of Chaska. The question we had is, we had heard that there had been issues with this lift station that services the Shadow Wood area in the past. They’ve indicated that they have taken the appropriate measures to go in and increase the wet well of that particular lift station and that they would have capacity for this site. At this time the City of Chanhassen will send a letter to Chaska formally requesting the connection. With regards to where it physically will be located, the sewer line would run within the Pioneer Trail right-of-way to Shadow Wood Court. Would connect to a sanitary sewer manhole that’s at the intersection of Shadow Wood Court and Pioneer Trail so we don’t have the specific alignment plan profile of that but, and I apologize we don’t have it on the screen but if you do have a packet, Civil Page 4.0 is the utility plan and that does show a close up of where that proposed sewer connection is so we have had those conversations. Excuse me, the conversations with Chaska to discuss you know why is the proposal going to Chaska versus Chanhassen. Just to give you a little bit of history, we did look at making a connecting to the north to the K. Hovnanian project to the north and as Sharmeen had indicated in her presentation there’s woods and slopes and a creek and significant slope elevation changes in there so that’s why pursuing that option, that option was not pursued. With regards to the elevation difference. There’s just, to kind of give you an idea of what the elevation difference is from the elevation of the wetland to the first floor of the building is about 20 feet so that can kind of give you, and that’s the slope of the ground. So that should give you an idea of the elevation difference. And then runoff to the site, on the north side, here’s that outdoor space that Mr. Pokorney was speaking about. There’s a pond, small pond that will treat the runoff from the parking area before discharging to the wetland here and then there’s a second, it’s an infiltration basin that will collect some of the runoff from the drive before discharging to the wetland so those are the two stormwater amenities that they are proposing to provide some treatment and some peak discharge attenuation. And his fourth question was regarding lighting which. Aanenson: I would just also indicate, it is our water. We will be serving with the City of Chanhassen’s water…and again the reason for the sewer is when we looked at the original proposal, there was significant tree loss with trying to bring it through that area that we were just talking about we’re trying to preserve so there was a decision made to say what’s the best way to preserve that overlay district is to come through Chaska… Al-Jaff: There was one other question regarding lighting on the site. Any lighting would have to meet ordinance requirements. 90 degree cut off. Not to exceed half a foot candle at property lines and all light fixtures have to be shielded. Aller: Anyone else? Come on forward. Welcome. Emily Owen: Thanks. My name is Emily Owen. I’m at 2706 Shadow Wood Court. I’m just to the north of Jeff Kerfeld and I share all of their concerns as well. I additionally, and I may have missed this in a presentation because I was a little bit late but my, one of my concerns is the road that comes out onto Pioneer. Will that, the traffic that it’s going to increase. I don’t know if visitor hours are going to, if there’s going to be hours or if it’s just going to be any time. What that’s going to do to the traffic on Pioneer and whether we’ll have to have a stop light. I guess there’s pro’s and con’s to either way so that’s my only question. Thanks. 14 Chanhassen Planning Commission – July 16, 2013 Aller: Thank you. My understand is, and anyone can jump in and correct me if I’m wrong. The State would be the one to come in and take a look at stop lights and the requirements for stop lights along that corridor. Aanenson: Or the County. Aller: Or the County and the use as requested is substantially less than the use that could be there so I think overall you’re looking at getting less traffic this way by far than if it is approved than if we leave it alone and let somebody come in and build under the zoning currently present. So is that a correct assessment? Aanenson: Yep. Aller: Any additional comments? Questions? Please sir, come forward. Keith Wyman: I’m Keith Wyman, 2674 Shadow Wood Court in Chaska. I’m not opposed to the project. I believe it’s a good use for the space compared to what could be in there. I do have some, a couple concerns. One is sight lines or the height. Finished floor is 20 feet above the pond with a I feel fairly steep roof. You know can that be dropped down at all? Can the roof lines be cut down so we’re not seeing this big roof up above the trees that is there? Is there anyway that that can be, you know can we drop finished floor down a little bit more? Create some retaining walls on the one side where we have that steep grade. Our houses now on the other side of the pond are probably you know maybe 12 feet, 10 to 12 feet above the pond. He’s going to be 20 feet above the pond. You know is there a way to drop that down to get those you know, the top of that roof down lower? And then also have concerns too with the sewer connection. I do understand the need for tying into Chaska. You know no, you don’t want to go through those, to the north. It just doesn’t make sense but when the lift station was put in it was sized for our neighborhood. Not for this addition so is it, you know we went to that meeting with, what Matt had a couple nights ago for you know he’s saying that it’s over sized already but I guess I’ve never seen a developer put anything in over sized in the past. Why would they over size this one? So, and you know it has had problems in the past so you know, if this does causes problems what is, yes it’s tied into Chaska’s system but where does Chanhassen or the owner going to do if it does happen so. Aller: Thank you sir. I know, most of the matters that come before us like you’re about the water systems and the safety systems and sewer systems being put in and my understanding is they look, just as we do, we have a 2030 plan. We look for future growth and that’s why you have systems in place to accept that growth when it comes and they never come but they try to do that so unless I hear something differently from staff, it sounds like Chaska has made that representation. Fauske: That’s correct. Aller: Anyone else? Comments. Concerns. Okay. Sure? We’re going to close it now. Close the public hearing. Comments. Questions. I like the fact that there’s diversity with the growing age of the citizenry of Chanhassen. We’ve looked at the demographics here recently and it’s good to have projects like these. I like the fact that we have a project which is going to allow for significantly less impact on the hard cover surface area and it looks like we’re preserving a great deal of the Bluff Creek system and of course the developer has to work with them as well so. With what’s in the report and the representations I think I would be looking to approve at this point. I’m not hearing anything that is going to sway me to say that we shouldn’t allow for the opportunity for the product to move forward. Hokkanen: Well I think we clarified the conservation of all those trees and areas that concern the K. Hovnanian and some of the others have talked about and the different elevations. It’s a nice project. 15 Chanhassen Planning Commission – July 16, 2013 Could be a lot worst in that development and higher density project. Could be much more difficult…so I think it’s a great addition to the city. Yusuf: I agree. It seems like a very good use of the… Aller: Okay. Any thoughts? Withrow: No. Aller: Entertain a motion if anyone would like to do so. Withrow: The Chanhassen Planning Commission recommends the City Council approve the rezoning of property from Agricultural Estate District (A-2) to Mixed Medium Density Residential District (R-8). Site plan approval for construction of a continuing care retirement facility called Bluff Creek Cottages. Conditional Use Permit to allow development within the Bluff Creek Overlay District, subject to conditions of approval and adoption of the attached Findings of Fact and Recommendation. Aller: I have a motion. Do I have a second? Hokkanen: Second. Aller: Any further discussion?
