3 CUP 8900 Audubon RoadCITY OF PC DATE: July 17, 2001 CC DATE: July 23, 2001 REVIEW DEADLINE: 9/15/01 CASE #: 2001-3 CLIP J L STAFF REPORT PROPOSAL: Request for a conditional use permit to construct a single-family home within the Bluff Creek Secondary Overlay District with a variance to allow development to encroach into the. required 40-foot setback of the primary zone. " LOCATION: APPLICANT: 8900 Audubon Road, Lot 2 Block 1 Sunridge Dennis & Ruth Chadderdon 5990 Charleston Circle Shorewood, MN 55331 PRESENT ZONING: RR, Rural Residential District 2020 LAND USE PLAN: Residential-Large Lot ACREAGE: 2.5 Acres DENSITY: N/A SUMMARY OF REQUE~ST: The applicant is proposing to build a single-family home. The lot is located within the Bluff Creek Overlay District and is adjacent to the primary zone. A conditional use permit is required prior to any construction within Bluff Creek and a variance is required from the 40- foot setback from the primary zone. Notice of this public hearing has been mailed to aH property owners within 500 feet. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City has limited discretion in approving or denying conditional use permits, based on whether or not the proposal meets the conditional use permit standards outlined in the Zoning Ordinance. If the City finds that all the applicable conditional use permit standards are met, the permit must be approved. This is a quasi-judicial decision. The City's discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Zoning Ordinance for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi- judicial decision. -- , .. es! V "~ ~ a~p Chadderdon CUP July 17, 2001 Page 2 APPLICABLE REGULATION Section 20-1554 of the zoning ordinance requires that conditional use permits be issued for all site plans, and prior the erection or alteration of any building or land within the Bluff Creek Overlay District Section 20-1555 allows the Planning Director to adjust the boundary of the Bluff Creek Overlay District, based upon data provided by a professional. Section 20-1563 requires the primary zone to contain 100% open space. Section 20-1564 of the ordinance requires a 40-foot setback from the Primary Zone with no disturbance within the first 20 feet. Section 20-591 of the ordinance states the intent of the "RR" District is to provide for single-family developments. PLANNING COMMISSION UPDATE On June 17, 2001, the Planning Commission held a public hearing and unanimously approved this item. During the discussion, the commission expressed interest in requiring an additional vegetative buffer adjacent to the outer boundary of the primary zone (881.6). The commission changed conditions of approval 7, 10, 11, 14, and added condition 16. This report has been updated. All new information is in bold. BACKGROUND In October 1998, the City approved a metes and bounds subdivision creating the subject site. In December 1998, the City adopted the Bluff Creek Overlay District Ordinance (two months after this lot was approved). The intent of the Bluff Creek Overlay District is to allow development to "blend into the natural environment while protecting Bluff Creek and sensitive land areas abutting and in the vicinity of the watercourse and its tributaries." The applicant is proposing to build a single-family home on this property. The main issue with the lot is that it is mapped entirely within the primary and secondary zones of the Bluff Creek Overlay District. The district regulations for the primary zone require that open space consist of 100% open space, and all structures setback 40 feet from the primary zone with no disturbance within the first 20 feet. In addition, a Conditional Use Permit is required for all development within the Bluff Creek Overlay. This ordinance does not exempt lots of record. Since this lot was created 2 months before the Bluff Creek Overlay District ordinance was adopted, the proposed lot was not required to meet these standards during the subdivision process. The strict application of these standards would result in this lot being unbuildable. Chadderdon CUP July 17,2001 Page 3 On May 18th, the applicant submitted an application for a conditional use permit with variances. A wetland delineation, detailed survey and proposed site plan were included with the application. Section 20-1555 of the ordinance states, "the planning director shall make a determination to maintain the officially designated watershed zone boundary or if the boundaries need to be corrected on city plans and maps based upon the data that is supplied." Staff studied the data provided by the applicant and conducted research on site characteristics of the property. Bluff Creek and an ag/urban wetland are located along the southern portion of the site. The wetland delineation submitted by the applicant depicts the boundaries of the wetland to be located below the 100-year floodplain elevation of 881.6 for Bluff Creek (See Attachment 2). The area above the 881.6 flood zone elevation has average slopes that range between 3-9%. It has been farmed and is devoid of native vegetation. The creek has been dredged and straightened to provide drainage for agricultural purposes. This has eliminated much of the natural wetland vegetation and habitat on this site. The primary corridor is intended to be preserved as natural as possible while the secondary zone is intended to be protected and managed to minimize impacts of new development on the primary zone. The characteristics found on this site (above the 881.6 elevation) more closely fit the conditions and intent of the secondary zone. The boundary of the primary zone should follow the 881.6 contour instead of the boundary designated on the official zoning map based on findings discussed above, which included a topographical survey, wetland delineation, farming history of the site, and site characteristics. The map of the primary zone has been amended accordingly. With this change, the proposed home is located within the secondary zone. Variances from the required 40-foot setback from the primary zone will be required to make this lot buildable. The development of this site can be a tool used to enhance the Bluff Creek Corridor. It provides the opportunity to protect the creek from further degradation. A site inspection by the Water Resources Coordinator concluded that much of the vegetation on this site is not native to the Bluff Creek corridor. With the development of this property, staff recommends that a buffer strip be established adjacent to the 881.6 elevation, following the primary zone boundary. In addition, the portion between the wetland and the elevation of 881.6 must remain undisturbed. The property is zoned RR, Rural Residential. The intent of this district is to provide for single-family residential subdivisions intended for large lot developments (Sec. 20-591). A single-family home, as requested by the applicant, would be a reasonable use to this site. Prohibiting such a use could be considered a taking. Staff is recommending approval of the conditional use permit with variances. PROPOSAL/SUMMARY The applicant is requesting a conditional use permit to construct a single-family home on a lot within the secondary Bluff Creek Overlay District with variance to allow development to encroach into the required setback of the primary zone. Chadderdon CUP July 17, 2001 Page 4 The site is located on the west side of Audubon Road, just north of Lyman Blvd. A 2,640 square foot home is proposed for this site to be located on the northwest portion of the site, 20 feet from the north property line, and approximately 21 feet away from the primary zone (newly designated boundary). A septic system will be located near the northeast property line, as shown on the site plan. The driveway is proposed to be approximately 400 feet in length with grades of less than 10%. Access to the site will be via a previously existing driveway entrance off of Audubon Road. Table 1 COMPLIANCE TABI.E Ordinance Proposal RR Setbacks East (Front) 50 feet 340 feet West (Rear) 50 feet 70 feet North/South (Side) 10 feet/10 feet 20 feet/138 feet Wetland 10 ft average buffer + 40 ft 61 feet setback Creek 75 feet 102 feet ISTS (Septic) Buildings 20 feet 20 feet Property lines 10 feet 10 feet Primary Zone 40 feet/20 foot no grading Does not meet, see below DISTRICT REQUIREMENTS The site is encumbered by numerous setback requirements (See Table 1). The Rural Residential District requirements are 50 feet for the front and rear setbacks, and 10 feet for the side setbacks. The proposed home will exceed these setbacks. The required setback of structures and sewage treatment systems from the OHW of Bluff Creek is 75 feet. The proposed structure and sewage treatment systems maintain the required setback. A condition of the subdivision creating this lot stated a permanent drainage and utility easement was dedicated over the creek at the 100-year flood elevation of 881.6. This easement has been recorded and falls within the wetland setback area; therefore the proposed home will not encroach into the easement. ISTS The site plan shows two drain field sites for an individual septic treatment system (ISTS). When this lot was subdivided in 1998, these drain fields were approved based on soil borings. A condition of the subdivision was that each ISTS site must remain undisturbed and must be protected and identified before construction begins. Individual sewage systems must not be placed on disturbed or compact soils. To the best of staff's knowledge the area identified for the septic systems is the only area on the site that has remained undisturbed. The proposed septic areas meet the setback requirements for building and property line requirements. Chadderdon CLIP July 17,2001 Page 5 WETLAND There is one ag/urban wetland located on-site adjacent to Bluff Creek. Since this lot was created after the adoption of the current wetland ordinance, the applicant must maintain a 0 to 20 foot wetland buffer (with a minimum average of 10 feet) and a 40-foot setback from the wetland buffer edge. The proposed home meets this requirement, however the plans that were submitted do not show the required wetland buffer. A wetland buffer with a minimum average of 10 feet should be shown on the plans. GRADING Following the subdivision that created this lot, grading began for a driveway to provide access to it. The property owner obtained a grading permit for the driveway in July 2000. As of today, grading and construction for the first 250 feet of the driveway has begun, however, driveway construction will not be completed until construction of the proposed home begins. A condition of the subdivision of this lot stated that the driveway grade shall not exceed 10% and shall be paved for the first 40 to 50 feet off Audubon Road. The plans reflect a driveway that is in compliance with this condition. The existing portion of the driveway is setback approximately 17 to 20 feet from the 881.6 elevation. This is an existing situation and does not require a variance. DRAINAGE The northeast comer of this lot receives water from a swale along the west side of Audubon Road. Prior to grading occurring on the site, the water drained from the northeast comer of the property to the southwest, where it was intercepted by the wetland prior to flowing into Bluff Creek. Because the culvert proposed in the grading plan application was not installed, the water is not able to flow into the wetland. The applicant should provide a culvert under the proposed driveway at the lowest point so water will be able to drain into the wetland. The applicant should install riprap at the downstream end of the culvert in order to prevent erosion. PRIMARY ZONE SETBACK The following will require variances from the 40-foot primary zone setback, and the "no disturbance" area of the first 20 feet of the 40-foot setback. 1. A comer of the proposed house is approximately 21 feet from the primary zone, requiring a 19-foot variance. 2. One of the proposed septic areas encroaches approximately 30 feet into the primary zone setback. The septic areas could be shifted north to reduce the variance to approximately 20 feet. 3. The first 250 feet of the driveway is approximately _17 feet from the primary zone. Fill for the grading of this portion of the driveway has been placed next to the edge of the primary zone. Pe~nission to grade for the driveway predates adoption of the bluff creek ordinance. Access to this site was approved when this lot was subdivided in 1998, and this portion of the driveway is preexisting. The remaining portion of the driveway is proposed to follow the edge of the primary zone. Staff recommends leaving the current, existing portion of the driveway as it is, but moving the remaining portion of the driveway north so it and any fill needed for grading will be out of the 100- Chadderdon CLIP July 17, 2001 Page 6 year floodplain (881.6). In addition, staff recommends the silt fence be moved outside the 881.6 elevation, no fill placed below the elevation of 881.6, and the retaining wall be constructed and setback 20 feet from the primary zone (if the retaining wall is over 4' in height, it must be engineered). TREE PRESERVATION/LANDSCAPING There are no existing trees on site. Since it is located in the Bluff Creek Overlay primary zone, staff recommends; a minimum of three trees be planted on site. They are to meet the ordinance's minimum size requirements and be native species. Staff recommends a choice of Sugar maple, Basswood, Red Oak and/or Bittemut Hickory. The applicant shall submit a planting list. VARIANCE FINDINGS The Planning Commission shall not recommend and the City Council shall not grant a variance unless they find the following facts: a. That the literal enforcement of this chapter would cause an undue hardship. Undue hardship means that the property cannot be put to reasonable use because of its size, physical surroundings, shape or topography. Reasonable use includes a use made by a majority of comparable property within 500 feet of it. The intent of this provision is not to allow a proliferation of variances, but to recognize that there are pre-existing standards in this neighborhood. Variances that blend with these pre-existing standards without departing downward from them meet this criteria. Finding: Literal enforcement of the ordinance would make this an unbuildable lot. In this case, the applicant is proposing to construct a single family home on a lot encumber by numerous restrictions. The lot is zone Rural Residential. A single family home is a reasonable use of this lot. It is a use that is made by the majority of the properties within 500 feet. b. The conditions upon which a petition for a variance is based are not applicable, generally, to other property within the same zoning classification. Finding: The conditions upon which this variance request is based are not applicable to most other properties in the RR zoning district. While the BCO is located within a large portion of the City, a majority of the RR lots are not located within this district. Co The purpose of the variation is not based upon a desire to increase the value or income potential of the parcel of land. Finding: The variation is not solely based upon a desire to increase the value of the land but to construct a single family home upon which to live. This site was approved by the City as a buildable lot. d. The alleged difficulty or hardship is not a self-created hardship. Chadderdon CUP July 17, 2001 Page 7 Finding: The hardship is not self-created. The lot was platted prior to the BCO ordinance. The granting of the variance will not be detrimental to the public welfare or injurious to other land or improvements in the neighborhood in which the parcel is located. Finding: The granting of the variance will not be detrimental to the public welfare or injurious to other land or improvements in the neighborhood in which the parcel is located. With the incorporation of staff conditions, the long-term restoration of this portion of Bluff Creek will be improved. The proposed variation will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets or increase the danger of fire or endanger the public safety or substantially diminish or impair property values within the neighborhood. Finding: The variance will not impair an adequate supply of light and air to adjacent properties or increase the congestion of the public street. It will not endanger the public safety or diminish property values in the neighborhood. CUP FINDINGS When approving a conditional use permit, the City must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: Will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. Finding: The proposed project will not be detrimental to public health, safety, comfort, convenience of general welfare of the city, with the conditions of approval. 2. Will be consistent with the objectives of the city's comprehensive plan and this chapter. Finding: This area is zoned Rural Residential and is guided residential-large lot. The proposal will be consistent with the objectives of the comprehensive plan and the zoning ordinance if the variance were approved. o Will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. Finding: The proposed project is designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. 4. Will not be hazardous or disturbing to existing or planned neighboring uses. Chadderdon CLIP July 17,2001 Page 8 , o o o o Finding: The proposed project will not be hazardous or disturbing to existing or planned neighboring uses. Will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by. the persons or agencies responsible for the establishment of the proposed use. Finding: The proposed project will be adequately served by essential public facilities and services. It must have an approved well and separate individual septic treatment systems. Will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community. Finding: The proposed project will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community, it is served by a separate septic system and well. Will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. Finding: The proposed use will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. Will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. Finding: The proposed project will have vehicle approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. Access to the site is via an existing entrance. The existing driveway is being used to minimize additional grading. Will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. Finding: The project will not result in the destruction, loss or damage of solar access, scenic or historic features of major significance. Staff believes that we have an opportunity to improve the natural features of this area as part of the project, with the conditions of approval. 10. Will be aesthetically compatible with the area. Chadderdon CUP July 17, 2001 Page 9 Finding: The project will be aesthetically compatible with the area. 11. Will not depreciate surrounding property values. Finding: The proposal will not depreciate surrounding property values. 12. Will meet standards prescribed for certain uses as provided in this article. Finding: The proposal meets the standards provided in this article if the setback variance is approved. RECOMMENDATION Staff recommends that the City Council adopt the following motion: "The City Council approves Conditional Use Permit 2001-3 to construct a single family home within the Bluff Creek Secondary Overlay District with a variance to encroach into the required 40 foot setback of the primary zone subject to the following conditions: .

Name Address Chris B. & Leslie Erickson 1831 Sunridge Court Dennis & Ruth Chadderdon 5990 Charleston Circle, Shorewood Julie Hoium presented the staff report on this item. Blackowiak: Thank you. Commissioners, are there any questions of staff? Deb, you want to start? Kind: Yes Madam Chair. You talked about moving the septic systems north, and I did not see the variance, or I'm sorry, a condition for that. Is it in here and I'm missing it? Hoium: I didn't put one in there. If we want to add that, I can attach, add that condition. Kind: So you'd be okay with adding a condition to that effect? Hoium: Yes, we could. Kind: That would be a good idea. And then condition number 10 it talks about the retaining blank, think it's a wall, must be set back 20 feet from the primary zone. I see the retaining wall on here and right now it looks to be, it's not 20 feet. Hoium: It's closer than 20 feet. Public Present: Planning Commission Meeting - July 17, 2001 Kind: It's closer, okay. And it's possible to move that back? It looks like it's holding back quite a bit of contour there. Hoium: I'm not sure. That would be something for the applicant hopefully to answer. Kind: And on page 3 of the staff report you talk about the development of this site can be a tool used to enhance the Bluff Creek corridor. Other than creating a buffer strip, are there any other enhancements that this would? Hoium: Planting vegetation and trees along the outside of the primary zone. Other than the buffer strip, maintaining it. Preserving it. Not going in and doing anything to it. Kind: That's all I have for now. Blackowiak: Okay. Uli. Sacchet: Yeah Madam Chair, I have a few questions too. First of all I'd like to clarify the boundaries of the primary Bluff Creek Overlay District zone. In the report you suggest that 881.6 contour line should be considered the border. Is that a new element or can you give me a little bit of framework of how that come about? Hoium: Sure. On the official Chanhassen city map, this is how the red is the primary zone. That is how it is mapped on the official map. Based upon the data that the applicant provided, the wetland delineation, the site plan, survey and just going out and doing site inspections, and following, which section is it? Section 20-1555, which allows the planning director to move it based on the information provided, it was determined that it fit more with the primary zone at the 881.6. Sacchet: So putting it at that elevation line is actually reducing a little bit. Hoium: The boundaries? Sacchet: The boundaries. That's in the interest of the applicant so I'm sure they're happy about that. Hoium: Correct. Sacchet: Now when we're talking about a buffer strip, relative to this 881.6 line, we can't really do a 20 foot because the driveway's very close in some areas pretty much... Hoium: Correct. Sacchet: The septic as we said, if we move it we might be 20 away. The comer of the house will be close to the retaining wall potentially intrudes on it. How much buffer, I mean can we quantify how much buffer we put in there? Hoium: Just based on what we've looked at and the information we've had, I think staff discussed a 10 foot buffer might be able to fit in there. Following the outer edge of the primary zone. Sacchet: So if we could possibly do something like an average of 10 foot or something like that? Planning Commission Meeting - July 17, 2001 Hoium: Yes. Sacchet: Because in some areas it might have to be less. Hoium: Yes. Where the driveway comes into the property, yes. Sacchet: It would not be feasible to have an average of 20 foot buffer, would it? Hoium: I don't think so. It would be tight. Kind: Madam Chair, point of clarification. The buffer needs to be from the wetland edge, not from the primary zone marker. Hoium: We are, maybe I'm confused. I thought we were talking about adding an additional buffer on the outside of the primary zone. There is a buffer, 10 foot buffer from the wetland itself. Sacchet: I was talking about, you understood what I...from the primary. Hoium: This would be in addition to the wetland. Sacchet: Now that's a good point. Let's clarify that. We're really clear which one we're talking about. When we said that there's usually a 20 foot buffer required, that would be from the primary zone boundary out. Is that correct? Am I understanding this correct? Hoium: Correct. Sacchet: Okay. So on that basis it would be fair and equitable to put a requirement on that it would be 10 or 15 foot average from that primary zone boundary? Aanenson: Yes, it's going to be 10 plus. Sacchet: Okay. Okay. Yeah, because I think if we make a condition I'd like to be very quantifiable. Now the silt fence is not on there. That's something that should be added in. Hoium: It's actually in place right now. Sacchet: Oh, but it has to be moved. Hoium: It has to be moved outside of the primary zone. Sacchet: Because it's in the primary, so it would have to be moved outside of that primary zone line. Hoium: Correct. Sacchet: How far is that one fifty foot along that driveway is actually in existence? That goes actually past that wetland thing or reaching north, isn't it? Hoium: No. It's about right there. Planning Commission Meeting - July 17, 2001 Sacchet: Because the reason why I'm asking, when I went out there I was under the impression that it was actually past the red line figure. Hoium: It' s possible. I think it' s, do one of the pictures show it. I think it' s right in that vicinity. Sacchet: Okay. Okay. And then...that raises another question. When we say that we recommend that the rest of the driveway would have more setback, we couldn't really do too much there anymore could we? Really the damage is basically done to the wetland from there on. It's away from the wetland. Hoium: Yes, that is correct. Sacchet: I just want to clarify whether my perception's accurate. Okay, that's my questions Madam Chair. Thank you. Blackowiak: Rich, any questions? Slagle: Just a couple of questions. Dove tailing on what Uli has suggested on the driveway Madam Chair, was there options to explore the driveway avoiding the wetland or is it I mean just said and done that it has to go across? Or adjacent to it? Hoium: Adjacent to it. Slagle: Yeah, I mean I guess what I'm wondering is there a real cost to moving that driveway further north? Haak: I guess I can speak to that a little bit. The driveway was put in prior to the city reviewing any sort of detailed plans. The city had approved a grading plan for the driveway and to the best of my knowledge it wasn't reviewed by myself or someone in my position, so we actually issued a Cease and Desist Order on the driveway just so we could make sure where the wetland boundary was so we could make sure that there was no additional fill. There right now is not wetland fill. It gets real close to the wetland boundary. I think any removal you do of material in that area, it' s kind of a 6 of 1, half a dozen of the other really as far as making the applicant remove the material versus just leaving the material where it is. It's outside of the wetland so I guess staff' s perspective was just to cut our loses and try to get the driveway, the rest of the driveway as far away as possible. Slagle: Okay. Blackowiak: Bruce, do you have any questions of staff? Feik: You said this was originally approved in '98. Hoium: Correct. Feik: If I recall the Park and Rec moved the trail to accommodate this driveway. At that time was there any consideration made to how this lot would have been accessed and was there any promises or indication given to the owner of the lot at that time how the lot would be accessed and where that driveway would go? Planning Commission Meeting -July 17, 2001 Aanenson: When this lot was created in 1998 simultaneously, I believe at that time there was a discussion on how that would be accessed. This parcel. Hoium: If I could add. The access was originally a farm access. Aanenson: Correct. So it's been there for a while. Hoium: It has been there. Aanenson: So that was kind of reviewed and as Lori said, we kind of cut our losses. Moving it, the degradation that you possibly could do. Again with the variance with this, you can attach reasonable conditions if you wanted to do some other things as far as mitigation to, for vegetation or whatever. You have that opportunity to attach a condition for that so we've decided that at this point trying to remove it probably is worse than, and that was part of the old farm road. Feik: Thank you. Sacchet: Can I clarify something? Blackowiak: Certainly, go ahead. Sacchet: That' s an interesting point. So that driveway was part of an existing farm road at one point? Hoium: Correct. Sacchet: Okay. Well that helps. Thanks. Blackowiak: I guess I just have a couple questions here. On the conditions, number 11, I just wanted to clarify, proposed walkout elevation of the home must be 2 feet above the OHW. I'm assuming you mean at least 2 feet? Hoium: Yes. Blackowiak: Okay. Wanted to clarify that. And the second thing has to do with the City Council resolution back in 1998, condition number 6. It talks about the developer paying full park and trail fees for parcel 2, and I'm not sure if this is parcel 1 or parcel 2. And if this is parcel 2, do we need to have a condition in there saying we need full park and trail fees? Hoium: Yes, this is parcel 2 and that was, I believe that was with the subdivision itself. Blackowiak: Okay. Now do we need to have a separate condition? Aanenson: Those are paid with the building permit. Blackowiak: It's okayed with the, okay. So we don't even. Aanenson: If you want to put it on there, that's no problem. Planning Commission Meeting - July 17, 2001 Blackowiak: No, if it's covered, I'm fine. I just wasn't clear as to whether this was parcel 1 or parcel 2 so I guess that's where I was coming from. Okay. Well if there are any other questions, then I'll ask the applicants or their designee to step to the microphone. State your name and address for the record. Dennis Chadderdon: I'm Dennis Chadderdon. I live at 5990 Charleston Circle in Shorewood. This is my wife Ruth. Ruth Chadderdon: Hi. Blackowiak: Okay, did you have anything you'd like to talk to us about this evening or anything that you'd like to clarify? Dennis Chadderdon: Not really. We're just here to you know, try to see the project through. We'd like to build a home on this lot and think it's completely possible to do. We know about the wetland situations and everything like that. Blackowiak: Okay. And based on the recommendations that the staff has made in terms of shifting possibly the septic fields, I mean how are you feeling about those recommendations? Dennis Chadderdon: We don't have any problem with doing what we can do with the septic system. The existing driveway is in to a certain point right now and continuing it and moving that a little bit north, we don't have a problem with. We've already discussed that with Julie. Blackowiak: Okay. Commissioners, do you have any questions? Start with you Bruce. Questions of the applicant? Feik: None, thank you. Blackowiak: No? Okay. Deb. Kind: I just want to make sure you had a chance to read all the conditions and you're okay with the conditions staff is recommending. Great. Blackowiak: Uli. Sacchet: Yeah, I have a few questions. The idea of adding a buffer like to that new line of where the primary zone boundary would be, is that something that you think is doable like a 10 to 15 foot average buffer? Dennis Chadderdon: Yeah. From the plans that we have submitted, I mean whatever it takes. We're not, we have no plans on infringing you know anywhere near the wetland. Sacchet: It probably means some extra planting or. Dennis Chadderdon: I'm sorry. Sacchet: You probably could translate it into some extra plantings on the south side of the driveway, which I would think you'd want to plant something anyhow. And then, let's see. The thing with the retaining wall, making that retaining wall any shorter. Is that a problem for you guys? Planning Commission Meeting -July 17, 2001 Dennis Chadderdon: The retaining wall on the front of the house? Sacchet: Right. Dennis Chadderdon: No. That, and that was drawn in by the survey people and if I can get away with you know shortening it, I have no problem doing that. Sacchet: Okay, so that's not... Good, thank you. Blackowiak: Okay Rich, any questions? No? Okay, thank you. This item is open for a public hearing. So if there' s anybody who would like to come up and speak before the commission, please step to the microphone and state your name and address for the record. Leslie Erickson: I'm Leslie Erickson. I live at 1831 Sunridge Court and we live in the lot just adjacent to where the building's going to be going on. And I have just a couple questions. I'm wondering if somebody could define this Bluff Creek Overlay for me. What exactly is an overlay? Blackowiak: Okay Kate, would you like to tackle that one. Aanenson: Sure. What the overlay district does is, it's an additional set of standards so there is the zoning ordinance. There's the zoning ordinance that regulates how you can use the lot. In addition with an overlay district it provides additional roles and regulations that you have to follow depending on if you're in the primary or the second zone. So it's an additional set of roles. And this example, the Bluff Creek is for those lots that are within a sensitive area of the Bluff Creek, and that line follows either a topographic features or their severe slopes. A wetland boundary or creek boundary, or if there' s a significant stand of trees. So this overlay district runs the entire kind of diagonal section of the city starting up at Lake Minnewashta all the way down to the Minnesota River. Leslie Erickson: Okay. Alright. And just to point out where we are, this is our lot here and so our home is here. They're I'm guessing that your home is going to be just right in this little comer. In that area, okay. We're a little concerned, and I don't know if you'll have to bring in a lot of fill up close to our property at all. Okay, good. And then when you talk about constructing the retaining wall, where is that going to be located? Dennis Chadderdon: That's in the front of the home. Leslie Erickson: On the front, okay. Dennis Chadderdon: It will be toward the road. Leslie Erickson: Okay. Aanenson: ...retaining wall right here. That's where we're asking them to cut the...so there's less grading. Again, that's the intent of the overlay district is to minimize disruption. Leslie Erickson: Okay, that's it. Thank you. Planning Commission Meeting - July 17, 2001 Blackowiak: Thank you. Would anybody else like to make comment or anyone else have a question? Seeing no one, I'd like to close the public hearing. Commissioners, now's the time to make comments. Rich, I will start with you. Slagle: I would just throw out a thought and that thought is, I mean I guess given what can happen in '98, where we stand today is okay with me. So I had a couple questions just regarding the intent of the applicant and after listening to it I felt pretty comfortable that they're willing to work within the conditions so. Blackowiak: Okay, thanks. Uli. Sacchet: It was interesting when I went out there looking at the site. I felt it actually is a sensitive area that can get impacted has already been impacted. It's that initial stretch of the driveway and it's certainly good to hear that that was an existing driveway for a farm before. The way I see it, the driveway really goes beyond that little finger of wetland that reaches north so there's not much we can mitigate there. And then the rest of the construction is basically away from the wetland that I think we have a pretty straight image here. I would like to add some conditions though to state that the septic system moves north. I'd like to quantify that a little bit. I'd like to ask that we consider a strip, a buffer strip beyond just the boundary of the primary zone since overall we ask for a 20 foot buffer. If we ask for an average somewhat smaller buffer, that is practical and is realistic in that framework, I think that would be balanced. And also with the retaining wall, I think it'd be fair to ask that there's an effort made to accommodate the standard setbacks in this type of environment. Other than that I'm fine with it. Blackowiak: Okay great, thank you. Deb. Kind: I agree with Uli and Rich's comments. I just have a question for Uli. Do you feel that condition number 1 that talks about the applicant shall maintain a 0 to 20 foot wetland buffer with a minimum average of 10 feet and a 40 foot setback from the wetland buffer edge, do you think that covers part of your request? And then coupled with number 14, which asks for a 10 foot vegetative buffer shall be established and preserved abutting the 100 year flood plain, so that would be in addition. Aanenson: That was our intent, correct. Kind: Between those two conditions, are you comfortable that it's covered? Sacchet: Well in terms of being equitable, I mean one of the efforts that we're making here is everyone treat everybody the same way. And it's my understanding that the 20 foot buffer would be required from everybody else of the primary zone boundary. Is that correct? Hoium: No. Sacchet: No, okay. Aanenson: The 20 foot from the primary, but you have the 0 to 20 so in some circumstances along that wetland it's going to average 0 to 20. In addition to that it's going to be 10 for the primary zone. Outside the primary zone. In some circumstances they're close to each other. Haak: That's what we're requiring. The 20 feet that we get with the primary zone is a 20 foot no grade. It's not necessarily called a buffer but everybody has that requirement. It's a 40 foot setback from the Planning Commission Meeting- July 17, 2001 primary zone so we don't really call it a buffer. We call it a no grade, no impact zone. But it in effect is the same thing. Aanenson: Yeah, so the mitigation is to make it a buffer. Haak: Right. Aanenson: That's what we're saying. It's a no touch zone but what we're implying is the mitigation and what you're saying, you have to landscape that and maintain a buffer. Sacchet: So in that sense you would have a valid point. That that is already covered in the current conditions. Okay. Yes. Kind: That's all Madam Chair. Blackowiak: Okay. Bruce. Feik: I just want to say that given previously the city has made some accommodations to allow for this lot, including some significant park and rec changes to the trail head and delay of the trail, I guess I'm just happy to see that it is finally getting resolved and a building going up. Blackowiak: Okay. And I just have a couple extra comments I guess. In the staff report they talked about a 40 to 50 foot paved area on the first part of the driveway, and I hope in a motion we'll see something. I don't know if we need to add that but I maybe would like to see that added. That the first 40 to 50 feet will be paved. Secondly, that the septic will be moved north, just like Uli said. Third, condition 11. That the OHW would be the marker and the walkout elevation be at least 2 feet above that. And then finally if someone would like to make a motion and talk about any kind of mitigation. You know when you're talking about 10 to 20 feet, we could certainly suggest additional vegetation or something. I mean I think that would be fair to kind of mitigate what's happening in this area so those are my comments. So if somebody would like to make a motion. Sacchet: Yeah Madam Chair, I move that the Planning Commission recommends approval of Conditional Use Permit 2001-3 to construct a single family home within the Bluff Creek Secondary Overlay District with a variance to encroach into the required 40 foot setback of the primary zone subject to the following conditions 1 through 14. In number 10 I'd like to add the retaining wall. The wall must be set back. In number 14 I'd like to read, minimum average 10 foot vegetative buffer shall be established and preserved abutting the 100 year flood plain. And I'd like to add a condition 16, that the septic system will be moved north as much as possible. Kind: I'll second that and I have a couple of friendly amendments if I could. Sacchet: Sure. Kind: You said conditions 1 through 14. Did you? Sacchet: Oh 15, sorry. Yeah. Kind: Okay. Just wondering if you were excluding 15 on purpose. Planning Commission Meeting - July 17, 2001 Sacchet: No I didn't. Sorry. So 16 would be the extra. Kind: And number 7. I'd like to add Alison's suggestion. Final grades of the driveway shall comply with the grading permit and add a second sentence that says the first 40 to 50 feet will be paved. Sacchet: That's fine. Kind: And number 11, did you say anything about the proposed walkout elevation of the home must be at least 2 feet above the OHW? Sacchet: Let's add it. Yep. Kind: And number 14, I just want to clarify. You changed it to say 10 foot minimum. Sacchet: Minimum 10 foot average. Kind: I was wondering if we could make it even stronger and say 10 to 20 foot vegetative buffer shall be established and preserved abutting 100 year flood plain. The buffer must average at least 10 feet? Sacchet: Yes, that would work. I mean we have to allow for areas where it's not going to be 10 foot because the driveway's so close there that it wouldn't work. Kind: If we say average it could be 0 in some spots. Sacchet: Well preferably it'd be more but. Kind: Theoretically. Sacchet: But if we say it the way you just said that it would be 10 to 20 feet with a minimum 10 foot average, I'm fine with that. Blackowiak: Okay, that's different so. Kind: Minimum 10 foot is it means it cannot go down to 0. Blackowiak: It could be a 0 then. Could we clarify please? Kind: Well a minimum of 10 feet. Blackowiak: That's totally different. Kind: That's totally different. I'll try it again here. Number 14 shall read, a 10 to 20 foot average vegetative buffer shall be established and preserved abutting the 100 year flood plain. The buffer minimum must be 10 feet. Sacchet: I don't think that's practical. It's not possible. I don't think it is. Please correct me. I mean what I've seen when I was out there, I really think that drive was closer than 10 feet in some areas. So I would say we could say something to the effect that any new grading or construction has to maintain the minimum of 10 foot. I think otherwise, what do you think Kate? 10 Planning Commission Meeting - July 17, 2001 Aanenson: Well, not to split hairs. We're going by the survey. The survey says you can get 10 feet so we're comfortable with what we put in there which is a minimum. If you want in those areas they can go more, I think that's great so if you want to say minimum of 10, averaging 10 to 20. So if there's areas where they can go more and you want to mitigate that by saying put more buffer in, that's fine. Sacchet: Point of clarification. You're saying that according to the survey they can maintain the 10 foot everywhere? Aanenson: Yes, based on what. Sacchet: Well then let's ask for it. Aanenson: That's what we suggested. Sacchet: Yep. Blackowiak: Alright, it's been moved and seconded. Uli, do you accept the amendments that were offered? Sacchet: Yep. Blackowiak: Okay. I'd like to vote on this motion. Sacchet moved, Kind seconded that the Planning Commission recommends approval of Conditional Use Permit #2001-3 to construct a single family home within the Bluff Creek Secondary Overlay District with a variance to encroach into the required 40 foot setback of the primary zone subject to the following conditions: . . . . . . The applicant shall maintain a 0 to 20 foot wetland buffer (with a minimum average of 10 feet) and a 40 foot setback from the wetland buffer edge. The buffer shall be shown on the plans. The applicant shall provide a culvert under the proposed driveway at the lowest point so water will be able to drain into the wetland. The applicant must submit drainage calculations to ensure that the proposed culvert is accurately sized. The applicant shall install riprap at the downstream end of the culvert in order to prevent erosion. The erosion control silt fence must be moved outside the 881.6 contour. Type Ill erosion control shall be installed as designated on the site plan. The current, existing portion of the driveway shall be allowed to remain in it's current alignment; however, the remainder of the driveway shall be moved so that no additional fill will be placed within the 100 year floodplain (881.6). Final grades of the driveway shall comply with the grading permit. The first 40 to 50 feet of the driveway shall be paved. 11 Planning Commission Meeting - July 17, 2001 8. There shall be no fill placed below the elevation of 881.6. , The existing public drainage and utility easement over the wetland (to the elevation of 881.6) must be shown on the plan as legally described. 10. The retaining wall must be set back 20 feet from the primary zone (881.6 contour). 11. The proposed walkout elevation of the home must be at least two feet above the OHW of the adjacent wetland. As such, the elevation should be 883.6. 12. Include the benchmark that was used for the site survey. 13. A minimum of three trees shall be planted on site. The applicant may choose between the following trees: Sugar maple, Basswood, Red Oak and/or Bitternut Hickory. The applicant shall submit a planting list. 14. 15. A minimum of 10 feet, averaging 10 to 20 feet vegetative buffer shall be established and preserved abutting the 100 year floodplain. The applicant shall comply with all conditions of Subdivision #97-11. 16. The septic system site shall be moved to the north as much as possible. All voted in favor and the motion carried unanimously 5 to 0. 12
