Public Present: Name Address Peter Kordonowy 810 Ramsey Avenue Martin Woody 4048 Spruce Road Bob Generous presented the staff report on this item. McDonald: Kevin, do you want to start? Dillon: You mentioned there would be a safety concern if windows were put in there. What's the safety concern? Planning Commission Meeting - March 6, 2007 Generous: Well just, the warehouse space they have, the equipment that they use in there, they can run into that. It's really pushing, storing things up against it and pushing against the window, you could run into. Cracking it. Dillon: And who's the tenant going to be? Generous: It's Heartland. Dillon: And what's the nature of their business? Generous: The applicant would probably be better to talk about that. Dillon: Okay, I'll ask that when they get up. Those are the only questions I had right now. Larson: I didn't have any. Thomas: No, I do not. McDonald: Kurt? Papke: What's the spirit of the transparency? The 50% transparency. Just to remind everybody, why do we require that? Generous: That's to provide a vision to the community, some night time light if you will from buildings out to the street so that people can look in and see activity. In this instance they wouldn't be able to see activity back there really. Papke: Isn't that true of a lot of office industrial type buildings? Generous: Well office space you'll see people working at night and you can see life in it, but in the warehouse space really is not conducive to that. Papke: I'm just struggling a little bit with the rationale behind this one. I certainly understand the safety concerns and I certainly understand the applicant's desire to do it, but I'm not fully grasping what, you know what our rationale is. Aanenson: When we put this PUD together, it falls in line with the highway corridor study that we wanted those buildings that had presence along collector roads, that would be more articulated. As Bob said, sometimes it's the light spilling out of a building, but you can see light in a building so you don't look at an expanses of dark walls. So in this instance the fact that it still has some articulation and has lighting underneath those panels that Bob showed you, that's another way to get, so the building has some life to it. You're not just in a cold space when so you're driving along that road. This does face a road that in some day in the future will be connected to 41. Right now it's not. As Bob Generous indicated, that this building, if it were to become office building could be modified to meet that requirement. Unfortunately, as the building was laid out, it now has frontage on two streets. 2 Planning Commission Meeting - March 6, 2007 Generous: Three streets. Aanenson: Three streets, and that's a little bit more, for an office warehouse, a little bit more onerous to try to meet that requirement, because typically what we say is when your street frontage should be the most articulated. In this circumstance it's three sided. So it's a little bit. Papke: And how big of a variance are we allowing on this? It wasn't clear from the verbiage. Generous: It's varied 10% rather than 50%. Aanenson: On a small segment of that building, yeah. Generous: Yeah, just on the north elevation. Papke: Okay. And if the usage were to change, the building were to change hands, what would be our mechanism at that point in time to revert to the 50% transparency. Generous: As part of the remodeling process, they would have to come in for a building permit. McDonald: I guess I'd like to pick up on that too because I'm having a problem with this. We do not like to grant variances. We like to make sure that if there's a reason for it, we should probably relook at our regulations to begin with. This makes sense from the standpoint of it's a warehouse. I understand that. But if we're going to say it's 50% as far as going to have windows, should we be looking at maybe something that says usage instead of just building by itself because otherwise the other problem I have with this is, they're putting the knock out's in there. It' in there for the windows. You know we're making them go almost to the step of the windows. You know do those knock out's and you should be able to meet it. And yet in their letter, what they're saying is is that, it becomes burdensome to put the windows in, but they're doing the knock out's. I'm having a little bit of a problem. Are we going to create a problem for ourselves with anybody else that comes in, again with warehouse and those things. It does make sense not to have all the windows. I understand that. But should we be looking at something a little bit deeper than this? I mean what, as you said, what was the intent of having the windows and what you've articulated to us is, yeah it's for office space and for you know people being able to see in, but we're applying it very broadly here and now all of a sudden we've taken a warehouse, which why shouldn't they have windows? Generous: And I believe that's part of the reason we have the variance process to look at those unique circumstances. We like to put the onus on them, or developers to meet our standards and then justify why they shouldn't. McDonald: Okay. And again I'll ask the applicant when they come up but I don't see where this is a big burden. So okay. With that I guess I would ask the applicant to come forward and add anything that you wish to add. 3 Planning Commission Meeting - March 6, 2007 Peter Kordonowy: Chairman McDonald, commissioners. Peter Kordonowy with Summerhill Commercial Real Estate. I'm the property manager of the building, the Heartland America building and I represent the owner. Appreciate the opportunity to discuss the building expansion and looking forward to moving forward on this project. This is the architect Martin Woody, and he can speak to the specific façade transparency issue. I think what he'll say is, even if we continue the punch out's on that north elevation, we will still need a variance. We're not going to be able to hit the 50% with the design. The building was designed in 1997 under those design criteria, and we actually can't hit the 50%. Now if we do continue the glass along the north end, we'll still be inadequate but I think from an ownership perspective, I'm not an owner. If they had to do that they would continue the glass on the north end, but it was in the design criteria of the building when it was built in 1997, and actually exceed those criteria by having continuous glass. The building does not have glass on the east side currently. And a good portion of the east side, there's not glass. But we could do as much glass on the north side as you'd like, as is on the east side. But we'd still be inadequate for the requirement. Martin Woody: Just to kind of reiterate what Peter had mentioned was, continuing the existing fenestration along the addition and along the north side. If we kept the same window pattern, even adding all the windows along the north side, we'd still be quite shy of the 50% requirement with the façade. The transparency requirement, which was adopted in 2001 and this building was built in '97 so. And then they do have a problem on the inside with storage up against windows because they utilize racking up against, of the exterior walls since they're loading and unloading the rack and comes in conflict with the windows on that side. We agree that you know should the building even become converted to office on that side, we'd be willing to add the windows at that point. Papke: Just to clarify, the fenestration, 50% transparency was enacted after this building was originally approved and built? Generous: Correct. Papke: So to some extent there's a grandfathering issue here. Also from a continuity and symmetry perspective, as you mentioned, it would certainly from an aesthetic goal, you'd like to continue the same patterning of the windows probably at most rather than all of a sudden coming up with a solid strip of windows there, just to meet this new code requirement. Martin Woody: Sure, there's some economies here as well. The pre-cast panels that are utilized in this construction, they're 8 feet wide so it's easy to punch a 4 foot window in a panel like that. If we say wanted to add a band of windows it would, one it wouldn't you know be consistent with the rest of the façade and it would add cost to the building because we'd have to run beams and what not to make that happen. Peter Kordonowy: Just to touch on that, I think it would create an unusual building because you'd have a strange addition look and then the existing building, and it would have a hybrid design that would not be complimentary to the park. 4 Planning Commission Meeting - March 6, 2007 Martin Woody: There's some, the existing south side of the building, where it is warehouse again existing now, there's reveals that mimic windows on the north side but there's not windows so, we're just trying to create that same appearance on the north side as well. A majority of the building frontages to the east so. McDonald: Anything else Kurt? Okay. Thomas: I think I'm okay, understanding a little bit better about the continuity of the building and trying to stay within the same look and feel of the building so that helps. Larson: Seems pretty straight forward to me. McDonald: Okay. Kevin. Dillon: So what is the business at the north end of the building? Peter Kordonowy: Yes, it's Heartland America. They are a mail order, home goods, or not home goods. Electronics, company. And they have computers, electronics, knick knacks. Globes, if you will. Just things people like to buy across the country. And so they're a mail order company. Heartland America and they're a catalog ordering business. Dillon: Do they take up the entire building? Peter Kordonowy: They're in 90,000 feet of the 100,000 square foot building. And so they would fully occupy this expansion, and so the good news is they're a local employer. Obviously increases the tax base in Chanhassen and being in Chanhassen's been a good thing for them and so this will be, this is an expansion for them. Dillon: I don't have any other questions. McDonald: You're going to have to understand a little bit about where I'm coming from on this because I really, we deal with a lot of variances and I have a real problem granting variances because if you grant them too easily, at that point why have them. It's real easy for people to come up here and say well you granted a variance to so and so. My problem with all of this is, again within your letter we talk about a hardship. I don't see a hardship. I see this based upon more or less usage instead of what the ordinance may have been pointed out to start with but I hear what you say about the grandfathering, the design criteria and those things. And I can buy into that. I'm okay. It's just you know one of the things that I probably want to talk to staff a little bit more about is, I think we need to relook at this. That there needs to be something that talks about usage. Warehouse, I would agree does not need windows, but at the same time I don't want someone else coming in here later on using you guys as an example and saying that we don't need windows either because we're going to store stuff in this particular part of the building. So I am going to go through this in some detail because I do want to create some kind of a record here that there's a reason for all of this. Now one of the things on the knock outs, you had mentioned something about those and that would be a requirement going forward, but what I visualized is that, I mean a knock out's kind of pre-cut into an area and you just kind of knock it 5 Planning Commission Meeting - March 6, 2007 out and it breaks at that point. That's not what I heard you say. What you're saying is that if we have to put windows in in the future, someone's going to have to go through a big effort it sounds like to put those windows in from the cut out panels. So this isn't just an easy, knock out that you would expect from furniture you buy that's already pre-cut and hit it and a piece falls out. Am I correct in that? Martin Woody: It's a little easier process with masonry construction versus pre-cast. McDonald: Okay. And then you mentioned things about other beams and everything. Yet what happens to the structural integrity of the walls? Is something going to have to be done there to shore those up if someone comes in and does something? Martin Woody: No, not in a pre-cast panel. They're structural panels that are 8 feet wide and the windows in this building, they're 4 feet wide. They fit in the center of the panel, so it's as easy as coming back. The manufacturer comes back with a saw and actually cuts the opening. McDonald: Okay, so if this gets converted then to an office space, this is not an extraordinary cost that's going to really, it's going to be a cost but I mean it's not something that someone can come back to us and claim, yeah because of this it's creating a hardship. This is not something that's extra ordinary as far as having to redo the building. Putting in new supports. I mean you're just putting in windows and the grouting and anything that would go around those. Martin Woody: Right. There'd be no special, or extra structural items needed to put windows in the panels, no. McDonald: And again if I'm understanding, the main reason why you want the variance is because structurally the rest of the building, the way it's built, this architecturally fits into that pattern. Martin Woody: It does. If you look at the building as a whole, actually the building, all the buildings in the development there, they're all real similar construction. Window types. What not. You know each panel has a window in it and structurally that's about what you can do with these panels. Putting in a strip of windows or a ribbon window system, not only would it you know destroy the character of the entire building but it would cost quite a bit more to make that happen. McDonald: Well from that point, the building wouldn't match the existing building. Martin Woody: Right. McDonald: Then the other thing, this entire building will be used for storage and for warehouse usage, is that correct? Martin Woody: Correct. 6 Planning Commission Meeting - March 6, 2007 McDonald: That is the primary purpose in doing this, so that the company that's moving in there can store things that they're selling. They need the extra space for that. Martin Woody: It's storage and distribution. McDonald: Okay. I guess other than that, I mean that's the only questions I've got about this really was dealing with this variance that we're looking at granting here tonight. I just want to make sure that we do it for the right reasons. Martin Woody: Yeah, I guess we wouldn't be asking for a variance if we didn't really need it. McDonald: Well I understand that. Even, or one of the things you said was, even if it meant that you'd still have to get a variance on the north side. Could you explain what you meant by that, because even at that you wouldn't be able to meet the 50%. Martin Woody: Right. We wouldn't be able to meet the intent of the ordinance the way it's written if we put windows in every panel along the north side. McDonald: Okay. Martin Woody: Along the north side and the addition side. We'd still be short. I think we'd only make it up to 30%. McDonald: Okay. I have no further questions, unless someone else wants to come back with something. Then I guess at this point I would open it up to the public and thank you all very much. Martin Woody: Thank you. McDonald: If anyone wishes to come forward and speak on this matter, please do so now. Well, seeing no one come forward, I will close the public meeting and I'll bring it back up for the council for deliberation and Kevin, do you want to start? Dillon: Yeah. You know I'm inclined to vote to grant the variance. I think that kind of given you know, it's either this or there's some other variance that we may be granting, or we wouldn't do anything at all and that would be harmful to the business and therefore present a hardship. I think that it makes sense. You know it's the right thing to do for this property. So your point Jerry about you know every we kind of straight down I'll say slippery slope of granting too many variances. I don't think we do that. I mean I think you know when these requests come before us, I mean there's always questions and challenge and properly considered and every one's a unique circumstance and by granting this one, I don't, it's not, and I don't want to mischaracterize what you said but I don't think we opened the flood gates to more or anything like that. There's going to be unique situations all the time. We just have to deal with those as they come. McDonald: Okay, fair enough. 7 Planning Commission Meeting - March 6, 2007 Larson: I'll agree with what Kevin just said regarding that. I won't repeat it. But also to the fact that it was grandfathered in in '97 and you know the fact that the city changed their views on it you know just a few years later, I'm all for keeping the style the same. You don't want to mess with the integrity of the structure you know and I think it's a nice design. It's an industrial design. Why mess with it. I mean if it's not really hurting anybody, I am inclined to go ahead and vote for the variance. Thomas: I'm going to also agree with the other two. I do agree that staff did a good job of bringing together the proposal and working with the applicant as to how the building will need to look and with it being that the ordinance was the way it was in '97, and now asking for additional, everyone's saying the same thing. We would have had to grant a variance no matter what so, I'm inclined to vote the same as well. Papke: I'm wondering if there isn't an opportunity here for a compromise, given that the street on the north side is eventually going to run out to 41. It's going to be reasonably high traffic. They're already putting in the knock out's for the windows. I guess one idea I'd float for discussion here is, if we had them put in the windows on the north side and they hit the 30%, that to me doesn't sound quite as ugly as 10%. And I don't think it would be over burdensome and again, I think it would give the building a uniform look to it. I think just to have no windows in the addition is going to make it look a bit odd, and to put in a strip window to meet the code is going to make it look odd. So I'm wondering if meeting the applicant halfway doesn't have some merit. Any thoughts? Larson: Is there any way that we could do it, have it be a condition as to the point where that road does open up, then it would have to be changed, or something like that. Papke: But then would you have them just, are you talking about putting in the windows or putting, or meeting code when the street goes through? Larson: Meeting code. Well no. Papke: But then they'd have to change the whole north side. They're not going to be able to meet it you know without ripping up the whole. Larson: …changing the windows at that point, but why do it now, you know what I mean? If it's not an issue at this point but at some point where it becomes an issue. Dillon: It's an aesthetic issue. Papke: It's an aesthetic issue now, and in the future, they're proposing putting in only a 10% transparency on the north side right now which means punch out's but no windows. Why not put in the windows, why not stipulate the windows now so at least it's uniform on the north side? Larson: It's an industrial building. Papke: It already is. 8 Planning Commission Meeting - March 6, 2007 Larson: I know but. McDonald: That's my point about the variance to begin with. Maybe the variance, maybe the regulation is wrong. Maybe it shouldn't be 50%. That's the whole point of looking at this is that, if we're going to have warehouses and industrial buildings come into town, we can't look at each one and be granting variances. We need to decide what it should be. What is appropriate for the use. We should not put burdens upon people that they cannot meet, and that's my point in all of this was to bring that up is that, 50% does sound like a rather high number and again, if it's based upon usage of the building, that should be factored into it. And it's not in this case. Papke: As you stated when we opened, we're not, we can't change the rules here tonight. McDonald: Right, and I'm not proposing that we do. What I again stated was that's probably something we need to go back and ask staff to look at. Aanenson: Mr. Chair if I could just add something too. We did include for you findings of fact of why we supported the variance and I just, while they're embedded in there, I want to make sure it's clear what our rationale was on that. The fenestration requirement is any street frontage, so because this is a 3 sided lot, and it's, the use of the building is predominantly warehouse storage, it's an anomaly in that respect. It should eliminate it from that requirement but the requirement did change. That would be one, some of the rationale. And the other one is, keeping in mind that this is a 25% expansion of a building that doesn't meet code, so while we're talking about 50%, it's 50% of that 25% expansion. So we were looking at that incremental change. Because our non-conforming says that if it's over 50%, then if you look at just a non- conforming building, because this was a smaller percentage, I just want to keep that in perspective. It's not a brand new building where we, you know it's following a prevailing pattern that they've already set in place, so it's trying to find that, what's the best way to get to the desired goal, and that's where we struggled and did recommend what we did in the staff report. McDonald: Well then part of what you're saying there is, that gets back to the grandfathering clause that what was there as existing must have met code at the time it was put up. Generous: Yes. Aanenson: Yes, so they don't have the 50% currently on the existing street, so when you're going beyond that on that extra 25%, so that's when we went back and said, is that onerous? Does that seem rationale? What's the nexus for that and that's where we struggled and kind of said, if we can provide that in the future the changes, but the way it's set up with that high of a building, it's set up to be office, excuse me, storage, warehousing with shelving and, could it be converted in the future? Sure, as any building in the city could. But that would probably involve a lot more structural stuff which I think Chairman McDonald, went back to your question. How much detail would be involved or how much work would be involved in changing that use. McDonald: Yeah, I guess with all of that, as Kurt has said, you know we're not here to change rules. I think what we're…this particular applicant because of the other things, it's just the way 9 Planning Commission Meeting - March 6, 2007 that it initially comes through. Any time you're going to grant 40% variance, I think we need to look at why are we doing that much. Papke: The only thing I'm kind of stuck on here is, if we're going to grant this, and why would we not at least have the applicant put in the same number of windows in you know, the same ratio of windows in the addition that they have in the base building? If we're going to grant a variance, why would we allow the applicant to go backwards in the fenestration ratio. You know it should at least maintain parity with what they already have. That's kind of what I'm getting stuck on. You know if we're going to grant the variance, why should we go backwards? That's one thing we try not to do with all of our variances. Larson: Is it all on the same side? I mean maybe I read this wrong. But isn't there a side of the building currently that doesn't have windows, or no? Generous: Yeah, the south elevation doesn't have windows either. Martin Woody: And the east elevation doesn't have windows as well. Papke: What we're kind of stuck on is, what I'm kind of stuck on is the north side. Larson: Why not extend it conforming with what they've already done? Papke: That's what I'm proposing, right. Are you, does the north side have windows all the way along or does the north side just have the punch out's? Right, and what the proposed addition has how many? Martin Woody: Well the east side. Papke: On the north side. Martin Woody: On the east side there's, part of it is windows and part of it is just reveal. So a lot of it on the east doesn't have windows as well. On the south side, most of it is reveals. Doesn't have windows. So there isn't a string of windows along the whole entire front of the building. Papke: What about the north side? Martin Woody: The north side there's 6 windows existing on the north side. Papke: Maybe I'm, do I have my bearings backwards or are you pointing at the west side? Martin Woody: This is north. Generous: So that's how this is sitting. Martin Woody: North is this way. Along this east wall it's not a continuous band of windows. 10 Planning Commission Meeting - March 6, 2007 Larson: So am I understanding it correctly or no? What you're adding, where you're adding, you're not putting new windows on the north edge, correct? Martin Woody: Correct. Larson: And then what about that little clip box corner? What's that? Martin Woody: There's 2 windows and an entrance on that. You can look here, it's an oblique angle here. There's 2 windows on each side of the entry. This is the, facing north and east. And this is the entire east elevation from here on. And this is the north. So this is, we're using this entire area as warehouse. Larson: Okay. Martin Woody: And on the south side of the building, it mimics this. There's just reveals here where there's no, the entrances are there. The entrance façade detail is there but there aren't any windows along there. Larson: So really the only windows are on the east side? Martin Woody: Right, and this is where the, this is the office area contains about this much, so this is actually open warehouse with the windows on the east side so. Larson: Okay. And does it pose a problem currently? Martin Woody: I think there is, that's a different function…part of the warehouse. Peter Kordonowy: The south side of the building actually has some windows come down part way about a quarter. Currently Heartland America does not have any windows in their warehouse and they have about 75,000 square feet of warehouse. So the east side, the long side of the building where the warehouse starts, doesn't have any windows. Martin Woody: Along the east side. Peter Kordonowy: On the east side, the current site. But currently Heartland does not have any windows in their warehouse area. Martin Woody: So it's not continuous with windows all the way along the east face of the building. There's reveals where windows could be. Peter Kordonowy: It stops right where the office, their office is about like this and so this entire length is non-windows until you get actually about the middle 50% is revealed edge on the existing building. Larson: Okay. 11 Planning Commission Meeting - March 6, 2007 Dillon: So anyways Kurt, to your comment about should we try to ask for a compromise, I think it's probably worth asking, but then the safety concern with the glass in the warehouse and all that stuff so, it's something that maybe we should pose to the developer just to get their reaction. McDonald: If you wouldn't mind getting coming back up there and addressing that. Peter Kordonowy: Sure. Well I do know that Heartland, we want to work with the City of Chanhassen and maintain the integrity of the look of the building and they don't have any glass in their current warehouse. Would they prefer to maintain that? They probably would strongly prefer it. Like to reach some kind of an equitable compromise. Still have the building look nice and uniform. It would add windows to their warehouse. They currently do not have that. If it's necessary they'd have to live with it. They probably would end up blocking it or something like that or screening it or plywood or something, but it could be done. Larson: Which means there's still no light coming out of those windows. Papke: You're not accomplishing the goal if you block the windows. Okay. McDonald: Okay, any other comment? Then at this point I would open it up for a recommendation. Papke: Mr. Chair, I'll make a motion that the Planning Commission recommends that the City Council approve Planning Case 07-05 for a 31,200 square foot office warehouse expansion to an existing 101,600 square foot building with a variance to permit only 10% building transparency on the northern building elevation. Plans prepared by Martin Woody Architects dated February 2, 2007, subject to conditions 1 through 25 as stated in the staff report. McDonald: Can I have a second? Larson: I'll second.
