PC Minutes 02-05-2013 CHANHASSEN PLANNING COMMISSION REGULAR MEETING FEBRUARY 5, 2013 Chairman Aller called the meeting to order at 7:00 p.m. MEMBERS PRESENT: Andrew Aller, Tim Tennyson, Kathleen Thomas and Lisa Hokkanen MEMBERS ABSENT: Mark Undestad and Bob Colopoulos STAFF PRESENT: Kate Aanenson, Community Development Director; Bob Generous, Senior Planner; and Alyson Fauske, Assistant City Engineer PUBLIC PRESENT: Ben Gowen 6440 Hazeltine Blvd Bill Cook 3748 Landings Drive Frank & Theresa Gustafson 6250 Chaska Road Julie Prohaska 6242 Landings Court Marty Campion Campion Engineering PUBLIC HEARING: TH FRETHAM 15 ADDITION: REQUEST FOR A FOUR LOT SINGLE FAMILY SUBDIVISION ON 2.29 ACRES OF PROPERTY ZONED SINGLE FAMILY RESIDENTIAL (RSF) AND LOCATED AT 6300 CHASKA ROAD. APPLICANT: CURT FRETHAM, PLANNING CASE 2013-04. Generous: Thank you Chairman Aller, commissioners. As you stated this is a subdivision review for th Fretham 15 Addition. Curt Fretham, the Lake West Development Company is proposing this development. It’s a four lot subdivision. It’s located on the corner of Highway 41 and Chaska Road. It’s approximately 2.29 acres in size. Access to the site will be limited to Chaska Road which is a local street. There is access control and also city ordinance that precludes the access directly to arterial roadways which is Highway 41. Again this property is zoned single family residential so permits single family detached housings. Minimum lot sizes are 15,000 square feet. All of these lot sizes are in excess of 20,000 square feet on a net basis so the proposed development does comply with the standards in the RSF district. Again this is a 4 lot subdivision. Each of the lots has adequate frontage on Chaska Road and adequate depth. Currently they’re proposing to move the existing house which is located on proposed Lot 2 over to Lot 4 but that’s not been completely determined and so whether they would be required to meet our building permit requirements for any of those relocations. The entire site will be graded as a part of the initial development of the project to create acceptable building pads and also to build a stormwater pond to treat the runoff from this site before it discharges into the wetland which is located north and the east portion of this development. Lot 1 was the only lot that had any concerns on staff’s part because of the wetland we wanted to verify that they could meet all the setback requirements and locate an acceptable house on this site. The developer does have a house plan that he submitted as part of the development review and he showed how that would fit within all the required setbacks on Lot 1. It is a constrained building envelope for this site so that, we had to verify that they could put the principle structure and then any accessory structures within the required setbacks from, and it’s a wetland setback requirement in this specific locations that constrained the site. The driveway grade, we just wanted to verify that they could maintain the maximum 10% slope and they have provided us with additional information that shows that they can do it. And finally due to the sewer elevation within the roadway, Lot 1 will require that an ejector pump be put into the house and we want to let people know up front that this Chanhassen Planning Commission – February 5, 2013 will be a requirement as part of any building permit process so that there’s no surprises for anyone who purchase that house. They are providing landscaping. They’re going to create an additional buffer along Highway 41 out of landscaping. While this doesn’t provide great noise attenuation, it will provide some screening for the houses that do into this development so. And finally we’re recommending that the Planning Commission approve the subdivision subject to the conditions in the staff report and that you adopt the attached Findings of Fact and Recommendation and with that I’d be happy to answer any questions. Aller: Had there been discussion about the overstory trees? I know there were a bunch of the overstory trees, are they going to be removed or are they safe based upon the plan that’s been submitted? Generous: Well, they showed building envelopes for all of them and that would be removed and as part of any review of the actual building permits we’ll work with them to see if additional trees can be saved or exchanged if you will. Aller: Was there any more discussion on the water and sewer project and whether or not they’re going to be able to get in with us to do that concurrently or are they going to have to fend for themselves? Fauske: Chairman Aller, if I may speak to that. As we, staff did the review of this development, and even in the pre-submittal meetings the applicant was made aware that the City would be in with a resurfacing project proposed on Chaska Road so the applicant’s always been aware of what the City’s timeline is for the resurfacing project and had indicated that he would be out of the street area prior to the City mobilizing the contractor into that area. After that conversation had taken place staff viewed the televising, the sewer televising and we’ve indicated that there’s some work that needs to be done in the area for utilities and in order to better coordinate the contracts, get everything done, I called up the applicant and indicated that there might be an opportunity for the City to include the service installations under the City project and assess those costs back to the developer and he had indicated he would be interested in doing that so we’ll keep up those conversations so that we can have a smooth transition between the city project and the developer’s desires to get the services in. Aller: Great, thank you. And it’s my understanding they meet all the wetland setbacks. Generous: That’s correct. Aller: Okay. I don’t have any further questions. Anybody? Thomas: No. Hokkanen: No. Tennyson: No. Aller: Alright, would anybody like to come forward? Developer, presentation. Homeowner. Marty Campion: Good evening. My name’s Marty Campion. Project Engineer with Campion Engineering. I don’t have any additional information to add. Just let you know that I am available for questions, if you might have any. Aller: You’ve received the report. 2 Chanhassen Planning Commission – February 5, 2013 Marty Campion: I’ve received the report. We’ve had a couple of conversations with both Alyson and Bob and are in agreement with the report and don’t have any, don’t see any issues with the requirements or the request. Aller: Alright, thank you. Okay with that we’ll. Frank Gustafson: Hi, my name is Frank Gustafson. I live in the property that is just to the north. Aller: Okay, what I’m going to do is officially open the public hearing. Frank Gustafson: Oh, okay. Aller: And now you can step forward. Frank Gustafson: There you have it. Well my name is Frank Gustafson. I live at 6250 Chaska Road which is just north of there. Of this, of the property in question and I just want to give my support to this. I see no issues with it whatsoever. I looked at the plat drawings and it looks like it’s not going to affect our wetland areas at all, nor will it adversely affect our property. I have not talked with, I don’t speak for the rest of the neighbors. I haven’t heard anything negative from any of the neighbors so you’ve got my support. Aller: Great, thank you for coming forward. Anyone else wishing to come forward, either speaking for or against. Seeing no one coming forward, I’ll close the public hearing. Open for commissioner comments. No one? Thomas: No. It’s pretty straight forward. Aller: I think the report was really well done. I think it’s nice to hear that you have community support for the development, proposed development and hopefully it will be on it’s way so with that, I’ll entertain a motion. Thomas: Sure, I’ll make a motion. The Chanhassen Planning Commission recommends approval of the th preliminary plat creating four lots for the Fretham 15 Addition, subject to the conditions of the staff report and adoption of the Findings of Fact and Recommendation. Aller: I have a motion. Do I have a second? Hokkanen: I’ll second. Aller: Having a motion and a second, any further discussion? Thomas: Nope.

PUBLIC HEARING: UTILITY METER READER POLE: REQUEST FOR A CONDITIONAL USE PERMIT AND SITE PLAN TO INTALL A 60 FOOT TALL STEEL UTILITY METER READER POLE ON PROPERTY ZONED OFFICE AND INSTITUTIONAL DISTRICT (OI) AND LOCATED AT 6400 MINNEWASHTA PARKWAY (CHANHASSEN FIRE STATION #2) AT THE SOUTHWEST CORNER OF MINNEWASHTA PARKWAY AND TH 7. PLANNING CASE 2013-05. Aanenson: This item is actually, the City’s the applicant on this application. It’s a request for a Conditional Use and a site plan review to allow for a 60 foot tower with a 10 foot antenna on top of that for a utility meter reader. This application is a part of a request by the City to put at the fire station this tower. And the fire station that we’re looking at is on Highway 7 and Minnewashta Parkway, so that’s the subject site. A little bit of background on this. We did a radius search, they did some engineering on this kind of looking at where we needed to, it’s called a propagation study where we needed to have the meters in order to get coverage of the city and if I may I’ll just go, oops. Talk a little bit more about the actual why we’re doing the water meter and the City Council approved a contract to replace the City’s water meters. Right now how they’re being read is they’re actually, you have a vehicle that drives around and picks up all the radio feeds and in looking at the equipment that we had and trying to replace those as the batteries have expired, they actually chose to go with a different system after a cost benefit so that now requires these antennas to be placed throughout the city. So I’ll go through a little bit more detail but a majority of them are on water towers throughout the city. There’s 6 other sites. The two sites that will actually be on other features. There’s one at Bandimere Park which is on, there’s a siren on already so this is just an appendix to that but this is now the only free standing one again based on that propagation study where this needs to go so looking at elevations and public properties that it could go on, this appeared to be the best site for that so again the City does have the ability with the conditional use to follow through the criteria in the office institutional zoning district which the subject site is zoned to place it if it finds the conditions necessary in the staff report based on the fact that looked at the land use. The use by the City. What the purpose is and reasonableness. The City felt that it met that criteria so where it’s being placed is behind the parking lot. You can see the star on the slide there at the end of the parking lot so there’s no vegetation there. There is no screening. There is minimal equipment but that is actually going inside the fire station itself so then really what it comes down to is the visual impact so with that the engineering department took some slides from different positions and it’s kind of hard to see but I’ll try to do my best here to show you where you can see the actual antennas. So if you’re looking at the parking lot where it’s sitting so in Pipewood Curve it’s very hard to see back there. You can see one here on Meadow Lane. Site 3. Site 4, you’re coming westbound on Highway 7 and you can kind of see that off. Oops, actually over on this site in the distance. From the lift station, number 3 looking across. Again now what’s sitting over there is actually a bucket ladder so it’s actually physically, it’s got the height correct but actually the bucket itself is quite a bit bigger. So this is actually if you go down then to the fire station itself where you would see, what you would see going down Minnewashta Parkway. The 6
