Finance Director Olson explained the 2021 State bonding bill provided funding for Big Island Improvements including ADA accessible trails, toilet facilities, picnic facilities and signage and the money was received into the general fund. This action moves the money to the park fund. Seals moved, Benson seconded to approve the 2022 Interfund transfer. VOTE: Ayes 5, Nays 0. 15. APPROVAL OF FIRE LADDER TRUCK REHAB AND EQUIPPING Nancy Brantingham, 3185 County Rd. 6, said she was at the Long Lake Fire Dept meeting that was held before the holidays. A number of citizens in Orono asked that the council provide an opportunity to meet and have information about this. She would like to know what the council’s response is to that request MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 3 of 10 and would like to add her voice to theirs. She noted the City of Orono does not have approval from Long Lake that they will go with Orono’s proposal and yet here we are with a fire truck. She said feel like “we have gotten out in front of our skis”. She would like to know more about this whole fire situation and doesn’t feel like residents have gotten enough information. Seals said both she and Council Member Johnson are on the negotiation committee and you are right that there is no agreement in place between the two cities (Orono and Long Lake) but between the cities served by Long Lake Fire there is no back-up engine. This truck would serve as back-up for an engine and as a ladder for the taller buildings in the City. One of the city’s greatest responsibilities we have is to provide fire service to our residents. A lot of equipment servicing this area is really old. Orono still has the opportunity to work with Long Lake and the City would be willing to put this truck on loan to them. While this might seem like putting the cart before the horse, this is making sure your fire fighters have the tools they need to get to your house when there is a fire. There are still ongoing talks. Matt and I met with the committee last month. They are supposed to be giving us a response after their next council meeting but that is in their control. Johnson said what’s in front of us right here is the conversation about rehabbing of that equipment. He and Seals attend Future fire services meeting that neighboring communities attend. There was a proposal coming from City of Wayzata. When we have a big fire then our neighboring communities assist with that fire and we do the same thing on the police side too. When the City of Orono has a fire that requires a ladder truck mutual aid comes. The Cities don’t pay one another for mutual aid. The other departments wanted Long Lake Fire to pay $700,000 for 10 years to contribute to their new ladder truck. That spurred a conversation and a great piece of government work. The City found a used ladder truck for $350,000 and it is being refurbished for under $200,000 and Orono will own it. We’ll get 10-plus years of service. He said it would allow the City to provide a better level of service to the community since it will be inside the City, instead of coming from abutting cities, adding it is the fiscally responsible thing to do. He said Orono has been paying for 85 percent of the equipment purchases through Long Lake Fire so would be paying 85 percent of this regardless. He said it’s a piece of equipment we understood that we need and we did a terrific job as a community creating a solution that saves the taxpayers money. Ms. Brantingham again asked the council to pay attention to the request that was made at the Long Lake meeting for a meeting for our city to continue to provide residents with information on this Long Lake/ Orono whole Fire Department situation. We just need information. Johnson said that time will be most appropriate when we know what Long Lake is going to do. We are waiting for their response. Right now we’re in limbo. In the meantime, we have to make sure you have fire service. Mrs. Brantingham thanked the council for the clarity but said I’m just asking again that the council commit to holding an informational-type meeting like what was done in Long Lake for citizens of Orono, so we understand what is at stake here and what it will cost Orono residents. Benson asked where the truck is currently and was told it is at the public works building. She asked if this dollar amount for rehabbing is for all of the items needed. Johnson explained the $70,000 cost was for refurbing by the manufacturer, multiple vendors are providing equipment for $115,000, and graphics for another $6,600 are included in the refurbishment and equipping costs. He said once it is ready it can be offered for training. Fire fighters would like to have MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 4 of 10 access to this vehicle as soon as it is fully operational. He noted acquiring a ladder truck has been on the capital improvement plan for a number of years. Edwards clarified the $70,000 included the cost of refurbishing by the manufacturer and work the city could do in-house. Benson noted that in reading the packet there seemed to be different gradations of rehabbing. Edwards said when ladder truck was first purchased the City had McQueen Equipment do an assessment of the vehicle and was provided a comprehensive list at the staff level. The first list is what had to be done to put the truck into service; secondly, what would be good to do if the city had the funds, and a third category that was more aesthetics, like $70,000 to change from one shade of red to another. We didn’t think that was necessary so we said we weren’t going to do that. There were items on the list we already had as a city or could use existing vendors. Tires went from $9,000 to under $4,000 as an example. Benson asked if $182,000 for rehabbing includes the first two categories but not the third, the aesthetics. Edwards said correct, there were items we decided not to do. The first item, $70,000, those are all of those maintenance-type items. The $115,000 for equipping is all of the things you need on an engine like hoses; all the things that make an engine do what it needs to do. The graphics are just that. Benson asked if the intention is that when the fire truck is done it becomes part of the fleet and is used right away. Johnson said that would be the ultimate goal but we would need an agreement with the city of Long Lake. Edwards said the truck has to be refurbished and equipped before it can be offered for training. In unofficial discussions with Long Lake, once it is at that point they would entertain idea of using it. My understanding is the fire fighters would like to have access to this vehicle as soon as possible. Seals pointed out the lead time to order a new ladder truck is three years and the cost is about $2 million. At the future fires services meeting they were saying in the area all departments are at risk. Just having it as a back-up is a huge value to all the communities. Benson asked if this has been in the works for a while. Edwards said the idea of having a ladder truck has been on the capital improvement plan for a number of years. Existing engines are nearing their end of life. This vehicle could become an engine to replace the ones that are aging out. Benson asked if this ladder truck issue is part of the negotiations with Long Lake or something we have been working on for some time. Fire Chief Van Eyll said when he was chief of Long Lake Fire Department they had a ladder truck on the capital improvements plan but it was moved around to be able to satisfy the limited capital funding. In future fire service meetings they found out both Wayzata and Maple Plain departments were talking about possible replacement of their apparatus and how much they were thinking about charging other MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 5 of 10 surrounding cities to share this equipment. That led to a discussion of is there a way to better utilize those funds and actually own this equipment. Long Lake’s two engines are running at about 20 years. A typical engine you want to keep it about 20 years. The last one we bought in 2017 was $475,000 and now they are close to $1 million apiece. Benson said she doesn’t argue at all that it makes perfect sense to look at rehabbing something instead of purchasing something new. She asked to be reminded when this truck was purchased. Edwards said in November or December. Benson asked if the expense for the truck was budgeted in 2022. Edwards said no, the truck was in the capital improvements plan and the opportunity to purchase presented itself. Benson asked if the improvements were budgeted for this year Edwards said the costs were added to the 2023 Fire CIP once the city knew it had the truck. Dave Dursen said he doesn’t question the value of the truck but does question the process. He said residents just found out at this meeting what it will cost to refurbish the ladder truck -- almost $200,000 on the refurbishing and about $350,000 on the truck itself. To spend $500,000 on this even though it is a good deal, he said, the process seems odd because no one in the community knows what is going on. He went on, it seems to him there ought to be a way to include the voters in what the council is doing. He asked if this engine can go into the fire station. He added that Orono has indicated it wants to get out of the deal with Long Lake by 2025 and asked if it is possible the City won’t be able to use the new ladder truck until 2025. Johnson said the City of Orono has purchased 100 percent of some of the equipment so this is not unprecedented in the existing relationship with Long Lake Fire. He said this isn’t a foreign concept in Orono’s longstanding relationship with them. Orono owns 100 percent of fire station number two and 50 percent of fire station number one and he doesn’t see a path of not using this truck until 2025. Mr. Dursen said he was talking about a legal path to use the truck if Orono and Long Lake can’t come to an agreement. He asked if the City had gotten bids or done an RFP for the ladder truck. Johnson said the truck was purchased from another department that was selling it so there were no bids but bids were taken for the refurbishment. He said this is not the first time the council has had public discussion at a council meeting about purchasing this equipment and the cost for refurbishing. The initial estimates were higher. He said this might be the first time for you but not the first time the council has had public discussion on this topic. Mr. Dursen said many people in the community have said they don’t know what is going on. He said there should have been a survey and a town hall meeting to ask people if they are aware that Orono and Long Lake are looking at going to separate fire departments in 2025. Why don’t we have the right to know how our money is being spent? MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 6 of 10 Johnson responded that the city records these meetings, and put them out live. I’m encouraged by the fact that you are here and learning more. That’s what we like to see. Meetings are on video and all the documents are online. Mr. Dursen asked about a town hall meeting to address why are we doing it, what’s the cost, what’s the alternative? He pointed out the action was on the consent agenda at this meeting. When did the public have a chance for input? Mayor Walsh responded the public had had a chance for input in August. September, October, November -- pick a month. It is on consent agenda now for refurbishing. He said Orono is the most transparent council. We’ve had these conversations consistently. Mr. Dursen said what you are saying is the public isn’t engaged. It’s your responsibility to get them engaged. He again asked for a town hall meeting, pointing out the city was having one the next night on pickleball. Johnson said the City doesn’t have anything for you right now until Long Lake makes a decision. They have told us that after the next council meeting they hope to have a counter or reply to our offer we gave them in October. Where the existing department is going to go is the first question that has to be answered. In meantime we have to go ahead and make sure we have adequate service for our city regardless of what Long Lake decides to do. We hope they are our partner. We have been very clear we hope going forward we have a relationship with them and keep the fire fighters together. I’m still very optimistic that Long Lake is going to come back to us realizing that very same thing but it’s in their court. Mr. Dursen said the City is spending money now on this equipment, $500,000 to 600,000, and have a fire chief hired at $120,000 a year for three years. He’s not going to be fire chief for three years but we’re going to pay him. I’m not saying that’s right or wrong but I think we as a community have the right to at least have the council present to us what is going on. Crosby said if the ladder truck had stayed on the CIP Orono’s cost would be about $1.8 million. Instead of spending $1.8 million the City is getting a good value on a used piece of equipment we are getting to refurbish that has really been a need going back 15 years. I was on the department for ten of those years. We should have had this years ago. This truck was a good value without waiting for the build. We are the budget. This isn’t costing us much more money. Orono is the budget for Long Lake Fire. That’s primarily where the money is. Mr. Dursen said he is not arguing the need but arguing the process. To me you need to let the community know. Ms. Brantingham said she appreciates the council wants to have all the details sewed up but when Long Lake had its meeting they acknowledged they didn’t have all the information yet but explained what they were wrestling with and asked for citizen input. You have to come out to your citizens and say here’s what we’re wrestling with. The community is in an uproar about this thing. Please reach out and do a council presentation about where you are at. You don’t have to have everything finalized. I would urge you to do more sooner rather than later. Seals said one of the things James (Van Eyll) is here for is to do a needs assessment. Is he going to be working? Yes, he’s working. MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 7 of 10 Johnson said the time is coming when there will be a lot more information to share. We’re just short of that. We’re doing an assessment. Long Lake has got to make a decision, whatever it is. When those two things come together there will be a lot to talk about. Kim Carswell, 261 Cygnet Place, said she feels like every time she comes to a meeting this is on the agenda so maybe it would behoove the City to have a separate meeting to put it all together. Seals moved, Crosby seconded to approve the fire ladder truck refurbishing and equipping. VOTE: Ayes 4, Nays 1 (Benson). COMMUNITY DEVELOPMENT REPORT 20. LA22-000055, ESKUCHE DESIGN O/B/O TRAVIS & SARA WILDENBERG, 3838 CHERRY AVENUE, VARIANCES Staff presented a summary packet of information. New owners are requesting variances to conduct a major home addition. City Planner Curtis explained the current home on the site is situated 20 feet from the high-water level of the lake almost entirely within the 75-foot setback. The project would require a 75-foot lake setback, average lakeshore and hardcover variances. Initially the plan included two small footprint additions and a second story proposed to extend all the way to the foundation of the lake side of the home. Staff recommended denial. The planning commission, at its November meeting, conducted a public hearing and voted 3 to 1 to recommend denial of the application. After the meeting the applicant removed the footprint expansion in the 75 foot setback and pulled the second story addition back 12 feet from the lake. The footprint for hardcover was increased on the street side to make up for the reduction on the lake side. Staff has changed its recommendation to approval on the revised plan, which still reduces hardcover 275 square feet. Sara Wildenberg, currently at 1421 North Arm Drive, the applicant, said they had been looking at lake property for a long time, noticed this one had been vacant about five years and contacted the previous owner and purchased it. She said she and her husband love the design of the house but it is not laid out for a family at all. The Planning Commission in November gave them a lot of good feedback, she added. The proposed addition would be stairs to get to the upper level that will extend over the garage. The area is hardcover right now. Sven Gustafson with Stonewood Renovations explained there were a few other removals lakeside including a planter wall near the lake and a patio and the second level was pulled back 12 feet which does change the impact from the lake quite a bit. Council Member Johnson stated this was a good example of the planning commission making recommendations that improved the plan. He said he was comfortable with the revised plan. Johnson moved, Seals seconded, to ask the staff draft a resolution to approve LA22-000055, Eskuche Design O/B/O Travis & Sara Wildenberg, 3838 Cherry Avenue, Variances VOTE: Ayes 5, Nays 0. MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 8 of 10 In further Community Development reporting, Community Development Director Oakden said the department is wrapping up end of year reporting and finished the year with just over 1,400 total permits. They are working on the planning commission packet for next week. FINANCE DIRECTOR REPORT Finance Director Olson gave a presentation on the final total for 2022 for building permit revenue which he said far exceeded the budget for building permit revenue which was $565,000 but came in at $713,737. The department is still working on overall totals for 2022 for the General Fund. CITY ATTORNEY REPORT Attorney Mattick had nothing to report. He said he would have a report at the next meeting in closed session. CITY ADMINISTRATOR/ENGINEER REPORT City Administrator/Engineer Edwards updated the City Council that Parks and Public Works have been very busy with snow and ice removal to make room for the next batch coming. Walsh thanked the Public Works Department for their work on plowing and clearing the streets for Orono during the past snow events. Johnson said he had received two resident calls thanking the City for taking over the snow removal on the Dakota Rail Trail, adding that it is a great public service. RECESS AND RECONVENE Mayor Walsh recessed the meeting at 7:08 p.m. The meeting was reconvened at 7:16 p.m. PUBLIC COMMENTS Brad Erickson, 2485 Independence Rd., stated it was unfortunate Mr. Crosby felt compelled to run out again tonight. He said he would need to clear up a few things to set the record straight and bear witness for his grandparents. He said his grandparents were born in Holland, married in 1939, and in less than a year the Nazis invaded and subjected them to things that were unthinkable, so when you send him videos invoking the deaths, the extermination of 6 million Jews, you have opened a door you will not close. Moving onto Mr. Crosby, there are a few things he said he needs to clear up after his (Crosby’s) diatribe a month ago about me (Erikson). He called me a clown. He said I’m bistrating him and degredating him. Those are not words but I have been berating him. He passed around a handout for the City that stated that Crosby was crowdfunding for the Proud Boys and showed a picture taken at the State Capitol steps that he said showed Crosby, asking what he was wearing on his knee here and his tactical gear. “He hasn’t been a fire fighter in four years but he is down there fighting BLM in and a tifa? Give me a break. This is a Stop the Steal rally; this isn’t a mask mandate rally.” MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 9 of 10 Mayor Walsh informed Mr. Erickson he had had his three minutes and the microphone was turned off and remained off for about two minutes. Janie Delaney, 1315 Woodhill Ave. said she was there to talk about development of historic land in Orono. She said the proposed project targets public land in Orono that has been dedicated to public golf since 1924. Orono Public Golf has the oldest golf league in Minnesota formed in 1948 and still active and was the first course in the state to have grass greens. The course is located in a quiet residential neighborhood. There has been no direct engagement strategy deployed by the City to enlist feedback from the neighborhood, golf community or the citizens other than the two scheduled open houses announced on Jan. 3. The project will decrease City open spaces and increase traffic and noise levels. Noise levels will go from seasonal golf and pedestrian sports to year-round noise levels of high-impact sports. Pickleball has been the subject of lawsuits across the country. Because it is a fast-growing sport courts have been built without adequate consideration for community impact. It is becoming increasingly known that pickleball construction is a project with serious community impacts when built in the wrong location. Already there is not enough parking at the golf course on league nights or busy days. Currently within 6 to 12 miles of Orono there are 85-plus public pickleball courts so it is already well-supported in the community and surrounding area. In 2019 the Orono Activity Center was built and has opened pickleball for the community. Communities around the metro area are looking into retro-fitting tennis courts and making better use of infrastructure that already exists. Casco Point is three miles away and has a skating rink used by youth hockey. A need for youth hockey ice time cannot drive City-wide spending. MAYOR/COUNCIL REPORT Benson stated in her first council that “it is an incredible honor to sit before you tonight as a member of the Orono City Council and the privilege is one of great responsibility and inspires both humility and gratitude. I was elected to serve as a representative of the people of Orono. It is important to acknowledge this position required continuous support and guidance and many people I want to acknowledge Orono City staff who has been welcoming and generous with their assistance from the moment I was a council member-elect.” She noted that she had participated in an orientation and thanked staff members individually. She added she plans to attend the League of Cities elected officials training the next month. She mentioned the importance of interpersonal relationships in city government. She said she would commit to listening and learning and treat with great care the trust that has been placed in her by the community and thanked everyone watching the meeting in person or on video. Seals said they have been working on the needs assessment for fire to get a fuller picture of what’s happening and get it out to the public. Thanks to DJ and the team because they had a lot of snow and the roads were better in the City than they were in the County. Johnson noted he and Seals had attended a future fire services meeting the previous week. There was talk of hiring another consultant but there didn’t seem to be a lot of interest in that. He said his recommendation is that the City not send any more staff to these meetings as there isn’t any real progress occurring. That could change but it’s general conversations you could get off the agenda. He thanked the community for re-electing him. He encouraged the public to continue to come, ask questions and read packets. MINUTES OF THE ORONO CITY COUNCIL MEETING January 9, 2023 6:00 o’clock p.m. _____________________________________________________________________________________ Page 10 of 10 Edwards said he would appreciate it not being a mandatory meeting but would like to keep the door open to attend to meet with staff counterparts in other communities on fire and other issues. Mayor Walsh congratulated Johnson and Benson and commended police and public works for handling of the snow and Long Lake Fire and first responders for taking care of people. He said he hears a lot about the transparency issue. Going back six to eight years the City didn’t have videotaping. This is the council that has brought videotaping of the City Council, parks and planning commission meetings. He stated this is the most transparent council the City has ever had. He added they also brought budgeting for sewer, roads and water and infrastructure that weren’t budgeted for before. They brought technology into the City the last eight years. It used to be everything was paper and it would take a few weeks. This council put website and permitting online and all the file cabinets they used to have at the city are gone. Papers have been scanned. People now can click on a property and know everything that has happened on a property. The city also bought 3-D technology for public works and now has information on every project done on those roads so it can budget and plan. The code review committee has updated and reviewed codes and looked at what has worked and what doesn’t in other cities. The City went through the comp plan a few years ago. The old plan would not vacate land. This council said it would look at every opportunity of old roads and alleys and things going through peoples’ yards and in the middle of the lake that shouldn’t be there. “We’re not giving away land we are solving problems – things that got done a long time ago that doesn’t make any sense.” There are two open houses coming up. People used to say this is Oro-NO. This council brought “yes” back to Orono simplifying processes and bringing down costs. ADJOURNMENT Johnson moved, Seals seconded, to adjourn the meeting at 7:40 p.m. VOTE: Ayes 4, Nays 0. ATTEST: _____________________________________ _______________________________________ Anna Carlson, City Clerk Dennis Walsh, Mayor Orono City Council Work Session Minutes Monday, January 9, 2023 Council Chambers 5:00 p.m. Page 1 of 2 PRESENT: Mayo r Dennis Walsh, Council Members Victoria Seals, Richard F. Crosby II, Alisa Benson and Matt Johnson. Staff members present were City Administrator/Engineer Adam Edwards, City Attorney Soren Mattick, Finance Director Ron Olson, Public Works Superintendent DJ Goman, Community Development Director Laura Oakden, and City Clerk Anna Carlson. 1. Navarre Parking Lot Discussion (Moved to top of Work Session agenda) City Administrator Adam Edwards gave a brief update in regard to the completion of the design. He is looking for input about resources to get the job done. Edwards presented the site layout and discussed the plans for updates planned for the lot. The drivers for the project was to repave and make the flow safer. A one-way path was created to help obtain that outcome. Part of the project not shown on the site layout is the addition and work for Stormwater management. Several courses of action could be taken to reduce the cost including, adjusting the scope, delaying the project, evaluating a portion of project benefiting other businesses, installing parking meters to help cover costs, or alternating funding for the plan. Mayor Walsh noted goal is to get it done because it is a long-term fix for Navarre and that the city should look at bidding it out with the Fox project. He noted that he would prefer if the city did not delay the project since it presents so many benefits to Orono as well as its businesses in that area. There was discussion related to the importance of finishing the project, keeping scope as shown. Council Member Johnson noted his support for the project, Seals also supports the project. Edwards noted that the next steps will be to finalize the design and put it out for bid with the other pavement projects planned for 2023; as an alternate project. He also noted that the city plans to add the Golf Course parking lot as an alternate project to the pavement bid as well. The city could decide to pull the project if need be, but that cost estimates for them would be beneficial. 2. THC Ordinance Discussion Police Chief Correy Farniok began discussion of the THC ordinance item. He noted the House and Senate are currently discussing the legalization of adult recreational use of marijuana which may change some of the processes for the current legalized products. He noted that there are a few samples of ordinances adopted by surrounding cities in the packet. Along with adopting an ordinance, the city would need to decide what businesses are allowed to sell it, restrictions for consumption related to on or off site, and how the city would license these products. Orono City Council Work Session Minutes Monday, January 9, 2023 Council Chambers 5:00 p.m. Page 2 of 2 Mayor Walsh asked if there are certain standards or rules currently in place that have been worked out and what those are. Walsh is concerned about how it would be tied to the license so it could be easier to enforce. Farniok discussed that the city should focus on how we will regulate the sale and permitted use of marijuana. We are hoping a template for licensing and enforcement. Attorney Soren Mattick noted that there is currently discussions going on pointing towards the further regulations of marijuana and or THC, but we do not know all of the details surrounding it at this time. We will know more about it later in the year and with that we will have a better handle on how to proceed. Walsh noted the city could leave it as moratorium for now to give time to figure out.

LA22-000055 WHEREAS, on October 19, 2022, Travis and Sara Wildenberg (hereinafter the “Applicants”), applied for variances from the City Code for the property addressed 3838 Cherry Avenue and legally described as: Lots 8 and 9, Block 3, Crystal Bay View, Hennepin County, Minnesota (hereinafter the “Property”); WHEREAS, the Applicants have made application to the City of Orono for a variances from Orono Municipal Zoning Code Section 78-1279 to allow construction of a second story addition 20 feet from the OHWL where a 75-foot setback is required and lakeward of the average lakeshore setback line; and WHEREAS, the Applicants have made application to the City of Orono for a variances from Orono Municipal Zoning Code Sections 78-1680 and 78-1700 to permit 32.9% hardcover where 33.9% currently exists and 25% is permitted to construct additions to the existing home and change the hardcover; and WHEREAS, on November 21, 2022, after published and mailed notice in accordance with Minnesota Statutes and the City Code, the Planning Commission held a public hearing, at which time all persons desiring to be heard concerning this application were given the opportunity to speak thereon; and WHEREAS, on November 21, 2022, the Planning Commission reviewed the application and provided direction to the Applicants for revisions; the Planning Commission recommended denial of the variances as applied; and WHEREAS, prior to City Council review, the Applicants provided amended plans reflecting the proposed second story 32 feet from the OHWL and a proposed hardcover reduction resulting in 7,380 square feet (32.6%) total hardcover; and WHEREAS, on January 9, 2023, the City Council reviewed the application and the recommendations of the Planning Commission and City staff and directed preparation of findings for approval of the variances reflected on the amended plans. CITY OF ORONO RESOLUTION OF THE CITY COUNCIL NO. 7336 2 NOW, THEREFORE, BE IT RESOLVED that the City Council of Orono, Minnesota hereby approves the requested variances as amended and described above based on one or more of the following findings of fact concerning the Property: FINDINGS OF FACT: 1. This application was reviewed as Zoning File #LA22-000055. The analysis contained within staff memos and the exhibits attached to the aforesaid memos, all minutes from the above mentioned meetings, and any and all other materials distributed at these meetings are hereby incorporated by reference. 2. The Property is located in the LR-1C One Family Lakeshore Residential Zoning District. 3. The Property contains 0.52 acres in area and has a defined lot width of 100 feet. 4. The Property is within Tier 1 and hardcover is limited to 25% according to the Stormwater Quality Overlay District. 5. Applicant has applied for the following variances: a. Hardcover Variance b. Average Lakeshore Setback Variance c. 75-foot Lake Setback Variance 6. In considering this application for variance, the Council has considered the advice and recommendation of the Planning Commission and the effect of the proposed variance upon the health, safety and welfare of the community, existing and anticipated traffic conditions, light and air, danger of fire, risk to the public safety, and the effect on values of property in the surrounding area. ANALYSIS: 1. “Variances shall only be permitted when they are in harmony with the general purposes and intent of the ordinance . . . .” The variances for expansion of non-conforming building within the average lake setback and the 75-foot lake yard setback are supported by practical difficulties. The established 75-foot lake yard construction prohibitions are intended to maintain the natural lakeshore and encourage development away from the lake. Additionally, the goal of the average lakeshore setback regulations is to protect views of the lake from neighboring homes. The requested variances to expand the volume of the existing home were designed to utilize the existing home footprint while maintain open space on the lakeside to reduce the lakeward mass and to preserve views for the CITY OF ORONO RESOLUTION OF THE CITY COUNCIL NO. 7336 3 neighbors are in harmony with the Ordinance. The reductions in hardcover and are also in harmony with the Ordinance. 2. “Variances shall only be permitted . . . when the variances are consistent with the comprehensive plan.” The variances resulting in modifications to the existing home including volume and footprint expansions in a residential zone are consistent with the Comprehensive Plan. The applicant has identified necessary practical difficulties inherent to the land supporting their requests. The minimization of the structural massing of the new second story within the lake setbacks is consistent with the Comprehensive Plan. 3. “Variances may be granted when the applicant for the variance establishes that there are practical difficulties in complying with the zoning ordinance. ‘Practical difficulties,’ as used in connection with the granting of a variance, means that: a. The property owner in question proposes to use the property in a reasonable manner, however, the proposed use is not permitted by the official controls. The existing principal structure is situated almost entirely within the lake and average lakeshore setbacks. The proposed expansion of the home lakeward of the average lakeshore setback and within the 75-foot lake setback is reasonable as the second story has been designed to minimize the lakeside massing. Additionally the variance reduce hardcover on the Property is consistent with the Comprehensive Plan. b. The plight of the landowner is due to circumstances unique to his property not created by the landowner. The existing house was not constructed by the Applicants. They have a right to maintain or re-build the existing nonconforming home in-kind. The proposed home expansions have been designed to minimize impacts to the lake and to neighboring properties. Additionally, the nonconforming hardcover is proposed to be reduced; and c. The variance, if granted, will not alter the essential character of the locality.” The proposed variances to expand the footprint and the volume of the home will not increase any nonconforming setback and will result in a reduction of hardcover. The proposal has been designed to fit within the character of the neighborhood. The home expansions and reduced hardcover are supported by practical difficulty and are consistent with the Comprehensive Plan. CITY OF ORONO RESOLUTION OF THE CITY COUNCIL NO. 7336 4 4. “Economic considerations alone do not constitute practical difficulties.” Economic considerations have not been a factor in the variance approval determination. 5. “Practical difficulties also include but are not limited to inadequate access to direct sunlight for solar energy systems. Variances shall be granted for earth-sheltered construction as defined in Minn. Stat. § 216C.06, subd. 2, when in harmony with Orono City Code Chapter 78.” This criterion is not applicable. 6. “The board or the council may not permit as a variance any use that is not permitted under Orono City Code Chapter 78 for property in the zone where the affected person's land is located.” This condition is not applicable, as a residential home is an allowed use in the LR-1C District. 7. “The board or council may permit as a variance the temporary use of a one-family dwelling as a two-family dwelling.” This criterion is not applicable. 1. “The special conditions applying to the structure or land in question are peculiar to such property or immediately adjoining property.” The conditions applying to the existing home are unique, and support the requested variances. 8. “The conditions do not apply generally to other land or structures in the district in which the land is located.” The location of the existing home is a unique condition which does not apply to other homes in the district. 9. “The granting of the application is necessary for the preservation and enjoyment of a substantial property right of the applicant.” The improvements proposed to the existing home will allow for the home to better function for a family with children. The variances are reasonable and preserve the rights of the Applicants. 10. “The granting of the proposed variance will not in any way impair health, safety, comfort or morals, or in any other respect be contrary to the intent of this chapter.” Granting the requested variances will not adversely impact health, safety, comfort, or morals. 11. “The granting of such variance will not merely serve as a convenience to the applicant, but is necessary to alleviate demonstrable difficulty.” The variances provide an increase in home square footage, improved aesthetic, and outdoor living space near the OHWL which improve the livability of the property and are designed in a way that minimizes new encroachments and do not increase existing nonconformities. CITY OF ORONO RESOLUTION OF THE CITY COUNCIL NO. 7336 5 CONCLUSIONS, ORDER AND CONDITIONS: Based upon one or more of the above findings, the Orono City Council hereby grants a variance to Orono Municipal Zoning Code Section 78-1279 to allow construction of a second story addition 32 feet from the OHWL where a 75-foot setback is required and lakeward of the average lakeshore setback line; and variances from Sections 78-1680 and 78-1700 to permit 32.9% hardcover where 32.6% currently exists and 25% is permitted to construct additions to the existing home and change the hardcover, subject to the following conditions: 1. Council approval is based on the entire record, above Findings. 2. The approved project shall conform to the survey dated October 27, 2022 and revised on December 15, 2022 and revised building plans submitted by the Applicants and annotated by City staff, attached to this Resolution as Exhibits A & B. 3. Any amendments to the plans which are not in conformity with City codes may require further Planning Commission and City Council review. 4. Authorities granted by this resolution run with the Property not with the Applicants, but are permissive only and must be exercised by obtaining a building permit for the new construction and commencing construction of said project. A building permit must be obtained within one year of the date of Council approval, or the variance will expire on that date (January 23, 2024). 5. Violation of or non-compliance with any of the terms and conditions of this resolution may result in the termination of any authority granted herein. ADOPTED by the Orono City Council on this 23rd day of January 2023.

Purpose. This application is regarding variances to expand the existing home in a nonconforming location. 2. MN§15.99 Application Deadline. The application was received on October 19, and considered to be complete on October 27th. The 60-Day review period has been extended and expires on February 24, 2023. 3. Background/ Summary. The existing home on the property is situated 20 feet from the OHWL, almost entirely within the 75-foot setback; most of home is also within the average lakeshore setback. The deck is cantilevered 7-feet over the lake. 4. Variance Description. The applicant has requested 75-foot lake setback, average lakeshore setback, and hardcover variances in order to conduct a major home renovation including additions to the footprint and creation of a second floor. Responding to Staff and Planning Commission feedback, the applicant revised their plan to remove footprint expansions and reduce hardcover proposed within the 75-foot setback (Exhibit A). The footprint expansions are shown in yellow on the inset image. A revised hardcover level of 7,380 square feet (32.6%) is proposed; reflecting a reduction of 51 square feet from the previous proposal and 275 square feet from the existing condition (existing 33.9%). Additionally, the proposed 2nd story has been pulled back from the lake approximately 12 feet, reducing the encroaching mass. 5. Planning Commission Vote and Comment. On November 21st, the Planning Commission held a public hearing. Following the public hearing the Planning Commission voted 3 to 1 on a motion to deny the requested variances as applied. Commissioner Kraemer dissented, indicating his support for the project. The draft minutes are attached as Exhibit E. 6. Public Comment. No comments from the neighbors were received. Item No.: Date: January 9, 2023 Item Description: #LA22-000055, Eskuche Design o/b/o Travis & Sara Wildenberg, 3838 Cherry Avenue, Variances Presenter: Melanie Curtis Planner Agenda Section: Community Development AGENDA ITEM Prepared By: mcc Reviewed By: LLO Approved By: 7. Staff Recommendation. The applicant’s plan to recapture the existing footprint results in limited legal areas for additions or expansions. The revised plan is an improvement over the previously proposed plan and provides a reduction in overall hardcover. The footprint expansions have been removed from the 75-foot setback and the 2nd story was reduced to minimize the impact of the massing on the lakeside. Staff finds the revised plans to be an improvement from the initial proposal and changes the staff recommendation to approval of the variances according to the revised plans.

Purpose. The purpose of the action item is to consider the joining of the Joint & Cooperative Agreement for Public Safety Purchasing. 2. Background / Summary. The Orono Fire Department will be an active participant in the west suburbs automatic aid/mutual aid/box alarm system. As communities within Hennepin County respond to incidents together, breathing apparatus among other items could become an issue. Different communities use different equipment resulting in potentially hazardous conditions, possible even life threatening, from the lack of common equipment. The Joint Powers Agreement is an effort to allow participating organizations the ability to purchase the same breathing equipment, ideally tested and maintained by the manufacturer, resulting in increased interoperability and life safety. 3.

Background/ Summary. In September, the City received complaints regarding a new parking area under construction at the subject property. Upon inspection staff confirmed that the property owner had installed an approximate 1,175 square foot paver parking area within the 75-foot setback connected to the existing driveway (highlighted in pink). Additionally, two additional unpermitted patio improvements were constructed on the property: a 500 square foot fire pit patio area on the north point of the property (highlighted in orange); and a second 470 square foot fire pit patio area on the east side of the home (highlighted in green). 4. Variance Description. The new parking area is situated 31 feet from the OHWL where no hardcover is permitted and a 75-foot setback is required. The parking area exceeds the maximum 8-foot driveway width permitted within the 75-foot setback. The two new patio areas have also been installed 43 feet and 50 feet from the OHWL where patio hardcover is not permitted. 5. Planning Commission Vote and Comment. On November 21st, the Planning Commission held a public hearing. Following the public hearing, the Planning Commission voted 4 to 0 on a motion for denial of the requested after-the-fact variances. 6. Additional Information. Following the Planning Commission meeting, the applicant provided an exhibit demonstrating the turning radius as well as a stormwater management report in an effort to support their unpermitted improvements attached as Exhibits G and H. 7. Public Comment. Other than the three individual complaints about the driveway installation, one neighbor comment has been received and is attached as Exhibit C. Item No.: 13 Date: January 23, 2023 Item Description: LA22-000051 – Paul Taunton, 3600 Ivy Place, After-the-fact Variances Presenter: Melanie Curtis Planner Agenda Section: Community Development AGENDA ITEM Prepared By: mcc Reviewed By: LLO Approved By:RJO 8. Staff Recommendation. The property was platted in 2018 with a home constructed in 2020. The original development plans contemplated a shared, connected back up area (shown in Exhibit E). Although the new home at 3570 Ivy Place installed their portion of the shared driveway connection, when the new home was constructed at 3600 Ivy, the builder chose not to install their portion of the shared driveway connection. Finding no practical difficulty supporting any of the illegally installed hardcover improvements, Planning Staff recommends denial of the after-the-fact variances. As this application originated as a property violation, Staff further recommends the applicant be provided a timeline for removal.

There is also a manhole at the beginning of the driveway. He has been talking with the utility company about burying that power line to give more stability. Mr. Johnson understands that utility easements will run that entire length of the property and clarified none of the other vacation requests has a utility on them. He stated they did not request vacation of the southern portion which the other neighbors all received. Libby asked Mr. Johnson about the old garage that encroaches on the easement and if that would remedy it. Mr. Johnson replied it would remedy it as it puts the garage in compliance. He was looking at remodeling the rambler for his parents and would not be able to attach a garage on that property because of the easement which runs right up next to the house. It cleans up the fact that the City allowed that garage there and it would get rid of the non-conformity. Libby thinks it is very important for people to speak their mind during public comments. He thinks it is unfortunate when they take time with hearsay and conjecture that is not empirically based in fact. Libby has been a real estate broker for 35 years and during Covid when they did not have the ability to register deeds the deputy registrars were months behind. He clarified when one is not seeing a deed filing it is because they are still catching up from being months behind during Covid. He believes it was a wrong pursuit to try to discredit another property owner in Orono because one could not find the deed as it was not the property owner’s fault. Ressler summarized he is in support of the vacation due to precedence and does not see a way that it would be suitable for the City’s public use without substantial investment in some sort of imminent domain because it is landlocked. If there is an amount of money to be exchanged and settled upon, he is fine with that and thinks that is reasonable but he is not qualified to determine how much that would be. Utilities have been addressed this evening and the easement will remain intact. Ressler would generally be in support as long as there are no rights being given up for the City to provide utility. This is the ability to clean up some parcels and supports the application as applied. Chair McCutcheon is in support of the yellow area and thinks there is a sticking point on the orange area. Kraemer thinks Ressler said it well. Ressler moved, Kraemer seconded, to approve LA22-000050, 1003 Wildhurst Trail as applied. VOTE: Ayes: 4, Nays 0. 2. LA22-000051 PAUL TAUNTON, 3600 IVY PLACE, REQUESTS AFTER-THE-FACT VARIANCE APPROVAL FOR HARDCOVER WITHIN THE 75-FOOT SETBACK FOR A PARKING AREA. City Planner Curtis gave a presentation on the item, stating the Applicant is requesting after-the-fact approval of variances for hardcover within the 75 foot setback. In September, the City received and confirmed a complaint regarding a new parking area under construction on the property. The property owner installed an approximate 1,100 square foot paver parking area within the 75 foot setback connected to the existing driveway. Upon review, Staff noted two additional unapproved patio improvements on the MINUTES OF THE ORONO PLANNING COMMISSION November 21, 2022 6:00 o’clock p.m. _____________________________________________________________________________________ Page 8 of 13 property with a 500 square foot firepit/patio on the north portion 43 feet from the Ordinary High Water Level (OHWL) and a 470 square foot firepit/patio area 50 feet from the OHWL on the east side of the home. The Applicant has identified lot size, shape, and safety as practical difficulties supporting the driveway variance and has not addressed the firepit/patio areas. The parking area is situated 31 feet from the OHWL where a 75 foot setback is required. Additionally, it exceeds the 8-foot permitted width of an allowed driveway encroachment within the 75 foot setback. Two new patio areas are in the 75 foot setback where hardcover is not permitted. Based on the updated as-built survey and hardcover calculations there is approximately 3,600 square feet of hardcover within the 75 foot setback where 657 square feet was approved. Curtis stated that 3,029 square feet of new, unapproved hardcover exists on the property within the 75 foot setback. A comment from a neighbor was received that was generally in support of the driveway improvements. This is a newly created lot; the property was platted in 2018 under the City’s current regulations. The plans submitted for the 2020 building permit for the home and the current owner provided the allowed driveway access permitted by the Code within the 75 foot setback. The home and driveway were designed to comply as much as feasible with the zoning Codes. Staff does not find practical difficulty supporting any of the after-the-fact hardcover setback variances. Planning Staff recommends denial and further recommends that the hardcover improvements be removed immediately. Jaime Wallis of Chanhassen, on behalf of Applicant Paul Taunton, said the initial violation was in relation to the driveway. The patios did not come up in the violations which is why they had not been addressed prior. Regarding the 8 feet allowed for the driveway, the problem is with the radius of the turn. Mr. Taunton had a driveway study done and one cannot make the turn in or out of the property without encroaching on the neighbor’s property and one cannot back out of the driveway. If they had an 8 foot or 11 foot driveway one would generally back out into a two-lane road but in this situation one would have to back out, go approximately 150 yards past three homes to another road to back out of the property. She gave photos to the Commissioners and noted the driveway turn is a significant problem. An easement was granted to access the property and Ms. Wallis stated a delivery driver or Amazon truck cannot get in there because they have to back out the entire length of the road which is a safety hazard. That was the reasoning behind it. Ressler noted Staff clarified how strict the City is, especially with lakeshore setbacks and hardcover, and if there is not a reason to rebuild in like-kind. It looks like it was made abundantly clear in the application. Ressler asked for a comment on the awareness. From Ms. Wallis’ understanding, the awareness of the 75 foot setback was there, and in the previous permit or survey that was approved, there is a hump in the purple area that allows for a turn. It was designed not to encroach any further to the lagoon side. Ms. Wallis thinks Mr. Taunton bought a property and was not aware that he could not access the property, build the home he wanted, and is now struggling to get a vehicle out of the property. Putting the patios aside, Mr. Taunton is just looking for some practicality regarding the driveway. Ms. Wallis took a video of trying to get on the property with a standard-sized truck which cannot be done without encroaching on the neighbor’s property. Trucks cannot deliver on the property so they park trucks in front of neighbors’ houses and block their driveway. Chair McCutcheon asked if the Applicant is concerned about hardcover so close to the lake. Ms. Wallis replied because they are permeable pavers, Mr. Taunton did not believe it was deemed as something that could not be in the space because water can flow through it. She noted he is still within the hardcover for the size of the property but the setback is causing the difficulty as Ms. Wallis understands. MINUTES OF THE ORONO PLANNING COMMISSION November 21, 2022 6:00 o’clock p.m. _____________________________________________________________________________________ Page 9 of 13 Chair McCutcheon opened the public hearing at 7:37 p.m. Penny Saiki, 2874 Casco Point Road, stated they knew about this from the beginning and if the owner didn’t know, the builder did. To say one cannot get out of their garage is a poor design and whoever designed it knew a 24 foot radius for a car is normal. The inside of the house is huge and they could have moved the garage up and had less of a foyer. Ms. Saiki stated it is bad planning on their part and it was not included on the permit. Chair McCutcheon closed the public hearing at 7:38 p.m. Ressler stated it makes sense for a turnaround to be there, however making sense is not a practical difficulty. Approving this would establish precedence for others with this type of application. That is where Ressler struggles. Chair McCutcheon stated in Orono one needs to know about average lakeshore setback (ALS) and he sees three structures now within the ALS which is a bad thing. The City cares about the lake and does not want runoff into the lake. The rules are there for a reason. Kraemer thinks the public comment received that it was very poor planning is very, very accurate. He does not think the Commission wants to set precedent in granting variances after the fact and it is a big red flag. It says that it is okay to do what one wants and then come back and ask for forgiveness. He feels bad that the homeowner did not get better advice or planning on this, but he has a hard time agreeing with the application. Libby noted this could have been remedied if there had been consultation with City engineering; it would have been recommended to build a little less house to allow for a different form of driveway access. The Applicant may not have realized the importance of pulling permits but one cannot create their own practical difficulty and could have built a slightly smaller house. He is not in support and agrees with Staff’s recommendations. Chair McCutcheon agrees with Libby. Ressler moved, Libby seconded, to deny LA22-000051 Paul Taunton, 3600 Ivy Place VOTE: Ayes: 4, Nays 0. 4. LA22-000055 ESKUCHE DESIGN, 3838 CHERRY AVENUE, REQUESTS VARIANCES FOR AVERAGE LAKESHORE SETBACK, 75-FOOT LAKE SETBACK, AND HARDCOVER IN ORDER TO CONSTRUCT ADDITIONS TO THE EXISTING HOME. Sara and Travis Wildenberg, Applicants, were present. City Planner Curtis gave a presentation on the item, stating the existing home on the property is situated almost entirely lakeward of the 75-foot setback line; most of the home is also within the average lakeshore setback. The Applicant provided an updated narrative, not included in the planning report, which was emailed and placed at the Commissioners’ seats. It includes a revised practical difficulty analysis. The majority of the existing single story home is situated lakeward of the average lakeshore and 75-foot lake setbacks. The lake side deck projects over the OHWL and the lake.

The permit under which this project was carried out allows 12,041 sf of impervious (and 70,360 sf pervious) to surface run off directly to the Lake, whereas 12,601 sf impervious (and 69,800 sf pervious) was built, per an as-built survey dated 10/27/2022. In addition, the permit allows 2,510 sf impervious (and 7,416 sf pervious) to drain towards underground filtration/detention pond 2P. The as-built survey shows that 2,999 sf of impervious and 6,927 sf pervious was installed for this drainage area. See the table below for the as-built conditions.

The as-built determined that the underground filtration/detention pond 2P was installed as approved and permitted. The as-built site discharge rates are un-changed from what was approved and permitted. The table on the next page shows the results of the hydrological model, and the maps on the following pages of this report allow a comparison between the proposed conditions approved as part of the permit and the as-built conditions. Further, the entire printouts of the proposed conditions and revised as-built hydrological models are also included. www.CivilSiteGroup.com 4931 West 35th Street • Suite 200 • St. Louis Park • Minnesota • 55416 (612) 615-0060 Rate Control Summary Table: 1-YR [2.47"]10-YR [4.24"]100-YR [7.50"] EX1 1.48 3.86 8.68 EX2 1.50 3.92 8.79 TOTAL (REACH)2.98 7.78 17.47 1-YR [2.47"]10-YR [4.24"]100-YR [7.50"] 1P (PR1A)0.21 0.59 1.16 2P (PR1B)0.11 0.82 1.75 2P (AS-BUILT 1B)0.11 0.82 1.75 PR2 2.57 6.25 13.42 AS-BUILT 2 2.57 6.25 13.42 TOTAL (REACH)2.86 7.52 16.11 AS-BUILT TOTAL (REACH)2.86 7.52 16.11 Overall Stormwater Rate Summary 1-Year Event 2.98 2.86 2.86 10-Year Event 7.78 7.52 7.52 100-Year Event 17.47 16.11 16.11 As-Built Conditions Rate (cfs) Proposed Conditions Rate (cfs) Drainage Area Stormwater Rate Summary Drainage Area Existing Conditions Rate (cfs) Proposed Conditions Rate (cfs) Existing Rate (cfs) Conclusions: The as-built conditions conform to the approved and permitted conditions originally proposed.

Upon inspection staff confirmed that the property owner had installed an approximate 1,175 square foot paver parking area within the 75-foot setback connected to the existing driveway (highlighted in pink). When notified of the violation, rather than removing the added parking area, the applicant has requested an after-the-fact hardcover setback variance. At the end of October, the applicant submitted the requested as-built survey showing the newly installed driveway improvement for the after-the-fact variance application. Upon review for the after-the-fact driveway variance, staff noted two additional unpermitted patio improvements on the property: a newly constructed 500 square foot fire pit patio area on the north portion of the property, 43 feet from the OHWL (highlighted in orange); and a second 470 square foot fire pit patio area 50 feet from the OHWL on the east side of the home (highlighted in green). Throughout the summer of 2022, staff worked with the property owner on several compliance issues prior to completion of the home’s Application Summary: The applicant is requesting after-the-fact approval of variances for hardcover within the 75-foot setback. Staff Recommendation: Planning Department Staff recommends denial. FILE # LA22-000051 21 Nov 2022 Page 2 of 5 construction. At that time the property owner made unapproved changes to the landscaping plan for the project involving vegetation alterations, and expansion of the approved sand beach area; in addition, the property owner installed unapproved hardcover within the 75-foot setback. City staff coordinated with the MCWD and the owner to bring the property into compliance. The property owner was informed about the strict hardcover limitations within the 75-foot setback and the hardcover was removed. In July 2022, the final as-built survey and final site inspection for the new home showed the approved driveway installed and in compliance with the approved building permit. The recent hardcover expansions were installed after the resolution of the above-noted violations and after the building permit was closed. Practical Difficulties Analysis Applicant Submittal Information: The applicant has identified lot size and shape and safety as practical difficulties supporting the requested driveway variance. The applicant has not addressed the additional hardcover variances associated with the fire pit patio areas. They have provided supporting documentation regarding Practical Difficulties attached as Exhibit B, and should be asked for additional testimony regarding the application. Planning Staff Practical Difficulty Analysis: This is a newly created lot; the property was platted in 2018 under our current regulations. The plans submitted for the 2020 building permit for the home for the current owner provided the allowed driveway access permitted by the Code within the 75- foot setback. The home and driveway were designed to comply as much as feasible with the zoning codes. Staff does not find practical difficulty supporting any of the after-the-fact hardcover setback variances. LOT ANALYSIS WORKSHEET Section 78-350 & 78-1279 – Setbacks: The parking area is situated 31 feet from the OHWL where a 75-foot setback is required. Additionally, it exceeds the 8-foot permitted width of an allowed driveway encroachment within the 75-foot setback (Cite 78-1282). Two new patio areas have also been installed without permits, 43 feet and 50 feet from the OHWL (within the 75-foot setback) where patio hardcover is not permitted. Section 78-1680 and 78-1700 – Hardcover Calculations: The overall property hardcover is conforming at 16.7%, the new hardcover within the 75-foot setback brings the property out of conformance. Based on the submitted as-built calculations and the as-built survey, there is approximately 3,686 square feet of hardcover within the 75-foot setback. This calculation reflects 3,029 square feet of unapproved hardcover on the property. The building permit-approved hardcover level within the 75-foot setback was 657 square feet. Stormwater Overlay District Tier Total Area in Zone Allowed Hardcover Existing Hardcover Proposed Hardcover Tier 1 62,013 s.f. 15,503 s.f. (25 %) 7,660 s.f. (12.6%) 10,949 s.f. (16.7%) FILE # LA22-000051 21 Nov 2022 Page 3 of 5 Applicable Regulations: Hardcover Setback Variances (Sections 78-1282 & 78-1680) With few exceptions, hardcover is prohibited within the shore setback zone 75-feet from the OHWL of the lake. A driveway with a maximum width of 8 feet is permitted within the 75-foot setback if the property has no alternate access. Additionally, patios and other hard surface improvements are not permitted within the 75-foot setback. Governing Regulation: Variance (Section 78-123) In reviewing applications for variance, the Planning Commission shall consider the effect of the proposed variance upon the health, safety and welfare of the community, existing and anticipated traffic conditions, light and air, danger of fire, risk to the public safety, and the effect on values of property in the surrounding area. The Planning Commission shall consider recommending approval for variances from the literal provisions of the Zoning Code in instances where their strict enforcement would cause practical difficulties because of circumstances unique to the individual property under consideration, and shall recommend approval only when it is demonstrated that such actions will be in keeping with the spirit and intent of the Orono Zoning Code. Economic considerations alone do not constitute practical difficulties. Practical difficulties also include but are not limited to inadequate access to direct sunlight for solar energy systems. Variances shall be granted for earth-sheltered construction as defined in Minn. Stat. §216C.06, subd. 14, when in harmony with this chapter. The board or the council may not permit as a variance any use that is not permitted under this chapter for property in the zone where the affected person's land is located. The board or council may permit as a variance the temporary use of a one-family dwelling as a two-family dwelling. According to MN §462.357 Subd. 6(2) variances shall only be permitted when: 1. The variance is in harmony with the general intent and purpose of the Ordinance. The variances for hardcover expansions within the 75-foot lake yard are not supported by practical difficulties. 75-foot lake yard hardcover and construction prohibitions are intended to maintain the natural lakeshore, increase infiltration opportunities, and encourage development away from the lake. The requested variances to expand the driveway hardcover and new patio areas within the 75-foot setback are not in harmony with the Ordinance. This criterion is not met. 2. The variance is consistent with the comprehensive plan. The variance to permit additional hardcover within the 75-foot setback is inconsistent with the Comprehensive Plan. The applicant has not identified necessary practical difficulties inherent to the land supporting their requests. The increase in hardcover within the protected 75-foot setback from the OHWL is inconsistent with the Comprehensive Plan. This criterion is not met. 3. The applicant establishes that there are practical difficulties. a. The property owner proposes to use the property in a reasonable manner not permitted by the official controls; Reasonable use of the Property is established with the existing principal structure including the minimal width access driveway. The request to permit an expansion of the driveway hardcover and to create two additional hardcover patio areas within the 75-foot lake setback is not reasonable. The proposal results in a 3,029 square foot increase of hardcover within the 75- foot setback and is not reasonable. The variance to install new hardcover areas FILE # LA22-000051 21 Nov 2022 Page 4 of 5 proposed within the 75-foot setback is inconsistent with the Comprehensive Plan. This criterion is not met. b. There are circumstances unique to the property not created by the landowner; The new home on the property was built in 2020-22 by the current owner. The driveway expansion and new patio areas were not included on the approved plans for the new home; no permits were obtained for the construction of the driveway or patios. The constructed expansions are not a right, are not necessary to preserve the existing home, and are not supported by practical difficulty; and c. The variance will not alter the essential character of the locality. The proposed variances reflect expansion of the impervious surface areas within the 75-foot setback and result in additional hardcover setback encroachments toward the lake which are out of character with the neighborhood. The new hardcover areas within the setback are not supported by practical difficulty and are inconsistent with the Comprehensive Plan. This criterion is not met. Additionally City Code 78-123 provides additional parameters within which a variance may be granted as follows: 4. Economic considerations alone do not constitute practical difficulties. Economic considerations have not been a factor in the variance approval determination. 5. Practical difficulties also include but are not limited to inadequate access to direct sunlight for solar energy systems. Variances shall be granted for earth-sheltered construction as defined in Minn. Stat. § 216C.06, subd. 17, when in harmony with Orono City Code Chapter 78. This condition is not applicable. 6. The board or the council may not permit as a variance any use that is not permitted under Orono City Code Chapter 78 for property in the zone where the affected person's land is located. A driveway exceeding 8-feet in width and additional patio hardcover are not allowed within the Shoreland Overlay District. 7. The board or council may permit as a variance the temporary use of a one-family dwelling as a two-family dwelling. This condition is not applicable. 8. The special conditions applying to the structure or land in question are peculiar to such property or immediately adjoining property. There are no obvious special conditions applying to the land which are unique, or support the requested hardcover setback variances. Beyond the existing home and location of the approved improvements on the property which was created by the Owner, the applicant has not identified special conditions to the land justifying the variance. 9. The conditions do not apply generally to other land or structures in the district in which the land is located. The Applicant has not identified conditions. This criteria is not met. 10. The granting of the application is necessary for the preservation and enjoyment of a substantial property right of the applicant. Substantial property right is provided by the existing principal structure. The Code provides for the minimal driveway hardcover FILE # LA22-000051 21 Nov 2022 Page 5 of 5 necessary to access the property which was installed with the home construction. Expansion of an existing improvement or structure is not a right. 11. The granting of the proposed variance will not in any way impair health, safety, comfort or morals, or in any other respect be contrary to the intent of this chapter. Granting the requested variances would be contrary to the intent of the zoning chapter. 12. The granting of such variance will not merely serve as a convenience to the applicant, but is necessary to alleviate demonstrable difficulty. The variances to increase driveway square footage, improve aesthetics, and increase outdoor living space near the OHWL are conveniences and are not supported by a demonstrable difficulty. The Commission may recommend or Council may impose conditions in granting of variances. Any conditions imposed must be directly related to and must bear a rough proportionality to the impact created by the variance. No variance shall be granted or changed beyond the use permitted in this chapter in the district where such land is located. Engineer Comments The City Engineer reviewed the as-built document provided. It does not appear that the parking pad encroaches into the drainage and utility easement covering the sanitary sewer and shoreline restoration area. Public Comments Other than the three individual complaints about the driveway installation, one neighbor comment has been received (Exhibit F). Issues for Consideration 1. Does the Planning Commission find that that the property owner proposes to use the property in a reasonable manner which is not permitted by an official control? 2. Does the Planning Commission find that the variance(s), if granted, will not alter the essential character of the neighborhood? 3. Does the Commission find it necessary to impose conditions in order to mitigate the impacts created by the granting of the requested variance(s)? 4. Are there any other issues or concerns with this application? Planning Staff Recommendation Planning Staff recommends denial. The hardcover improvements (driveway parking area and patios) should be removed. List of Exhibits Exhibit A. Application & Narrative Exhibit B. Practical Difficulties Documentation Form Exhibit C.
