Lake Elmo Planning Commission Minutes; 3-27-17 City of Lake Elmo Planning Commission Meeting Minutes of March 27, 2017 Chairman Kreimer called to order the meeting of the Lake Elmo Planning Commission at 7:00 p.m. COMMISSIONERS PRESENT: Larson, Dorschner, Emerson, Williams, Lundquist and Hartley COMMISSIONERS ABSENT: Fields, Kreimer and Dodson STAFF PRESENT: Planning Director Wensman and City Administrator Handt Approve Agenda: M/S/P: Dodson/Williams, move to approve the agenda as presented, Vote: 6-0, motion carried, unanimously. Approve Minutes: March 13, 2017 M/S/P: Lundquist/Dorschner, move to approve the March 13, 2017 minutes as amended, Vote: 6-0, motion carried unanimously. Public Hearing – Zoning Map Amendment – General Business to Village Mixed Use Wensman started his presentation regarding the rezoning of properties from GB to VMX. Since 2013, there have only been 3 properties rezoned to VMX based on applications received by the City. In 2016, the Planning Commission discussed rezoning all of the properties to VMX, but tabled it for the following reasons 1) densities within this area are guided too high 2) VMX standards are less restrictive 3) form based code should be created 4) updated population and development projections for area needed. The rational for the rezoning is to bring the subject perperties’ land use consistent with the Comprehensive Plan. Without the rezoning at this tiem, many improvements to these properties would require owners to rezone to VMX and obtain variances. Wensman went through the differences between GB and VMX such as lot width, lot area and impervious surface maximum. There are 83 parcels currently zoned general business. There are some parcels that are guided RS that are guided for VMX and there are a number of parcels zoned RS being used for business, not single family homes. The residential properties being used for business were not noticed, but should be included in this rezoning. Re-publication of the public hearing to include these properties would 2 Lake Elmo Planning Commission Minutes; 3-27-17 be needed. The properties that are guided for VMX, but currently used as single family residences, staff is not recommending rezoning at this time. Staff feels that single family residences should be an allowed use in the VMX. If that is the case, those existing single family homes could be rezoned to VMX as it would have no impact on them. New and existing homes should be treated the same. Hartley is wondering why there is long list of condition uses as part of the VMX district. Wensman stated it is the choice of the City Council to decide what is permitted and conditional. Some uses are conditional to allow greater scrutiny of those uses. In the Village, the lots and structures are very close to each other, so there could be uses that should have greater scrutiny with conditions put in place to mitigate unforeseen situations. Hartley thinks the veterinary services should be more specific to small animals, not large animal services. Wensman stated that if there are specific changes to the code, that code be discussed through the public hearing for the zoning. Williams is wondering if the City Council responded to the June Planning Commission request for updated population projections for the Village area. Wensman stated that they did not specifically respond. They have now launched into the Comprehensive Plan process and it will be addressed through the process. Williams is asking if there were 2 houses fairly far apart on existing lots, could they then subdivide and build another house. Wensman thinks there are greater requirements for single family homes, but he will look at it. Williams asked about the status of the form based code. Wensman stated that with the Comprehensive Plan update, the priority for form based code was lowered. Emerson asked how many single family homes would be affected if they change them to VMX. Wensman thought maybe around 30 properties. Williams asked what the downside would be of those properties being legal non-conforming. Wensman stated if the home burned down, they could only rebuild on the footprint and would not be able to expand without a variance. Williams is wondering about making single family homes conditional uses. Wensman stated that might be a good solution. Public Hearing opened at 7:32 pm Sue Dunn, 11018 Upper 33rd Street, she would like the Commission to really think about what things should be conditional uses. She is concerned about surface water and impervious surface. She thinks the VMX could possibly add an additional 10,000 people in the Village Area. She is concerned about the existing businesses. She thinks single family homes are important to the Village Area. She thinks it is important to know what the projections are for 2040 and how close we are to meeting those projections. There is also a huge section to the East that is considered part of the Village area. There were no written comments 3 Lake Elmo Planning Commission Minutes; 3-27-17 M/S/P: Dorschner/Williams, move to continue the public hearing for the Zoning Map Amendment Discussion to rezone properties to VMX – Village Mixed Use to the next possible meeting in order to properly notice the public hearing to include the additional properties in the Zoning Map Amendment, Vote: 6-0, motion carried unanimously. Public Hearing – Comprehensive Plan Amendment to add 2 properties to RSF Sewered Wensman started his presentation regarding adding 2 properties to the Olson Lake Trail sewer area and re-guiding them to Rural Single Family sewered. This would add 4497 & 4473 Olson Lake Trail to the MUSA. The feedback from the Met Council is that it would just be an administrative review and would be similar to what was done in the Village to add additional properties. This does not require any jurisdictional review as we have a joint powers agreement with Oakdale. We have not received any comments from the public notice sent out and advertised. Dorschner asked what the Oakdale capacity would be for hooking up the rest of the properties around Olson Lake on that road. Wensman stated that they are not in the MUSA so there has been no talk about Oakdale picking them up. Wensman stated that they do not know, because there is no plan for it and the property owners are not requesting it. Handt stated that the Engineers did reach out to neighboring properties to see if they wanted to be included, and these were the only 2 properties interested in being included. Williams is wondering if there is a Zoning Text that is actually rural single family sewered. Wensman stated that the City does not have that specific zoning, but it is probably something that could be created. Wensman stated that there really is no problem leaving them as Rural Single Family zoning, but the change to the land use designation was something the City Council was interested in to distinguish those properties within the MUSA. Met Council was only concerned with land use designation in the Comprehensive Plan allowing for sewer connection. Emerson is wondering if they would move the MUSA line without the property owners asking for it. Wensman stated that the City has not required properties to be sewered unless the property owner has petitioned for it and signed a waiver. Public Hearing opened at 7:44 pm No one spoke and there were no written comments Public Hearing closed at 7:45 pm M/S/P: Dorschner/Lundquist, move to recommend approval of the amendment to the City’s Wastewater Facilities Plan by adding PID #’s 090292132001 & 080292140059 to the Olson Lake Trail MUSA, Vote: 6-0, motion carried unanimously. 4 Lake Elmo Planning Commission Minutes; 3-27-17 Hartley stated that they are adding these properties because they specifically requested it. Looking at the map, there are potentially 4-5 properties that would seem to fit the same characteristics of the other properties and why they requested it. Why is the City not adding those properties? Williams stated it is because they did not request it and according to Handt, they actively declined by not responding. Wensman stated that there was one additional parcel that was thinking about it, but after further discussion with the Engineer, they declined. Dorschner is wondering if we have the means through the MUSA to require connection. Wensman stated that with the joint powers with Oakdale, we have the means to connect these properties. Dorschner is concerned that properties along the lake are still on old septic systems and what that means for the future. Hartley stated that he is concerned because the City does not have a very good mechanism to catch when drainfield fail and so we end up with even one house affecting the Lake. Handt stated that most septic problems are caught when the properties are sold or a building permit is issued. Williams stated that the same logic for the additional properties could be applied to the whole Tri-Lakes area. If the MUSA was opened up to the whole Tri-Lakes area, there would be numerous people speaking against it. Wensman stated that there are a number of 201 septic systems in this area that have been created to deal with some of the failing septic systems. M/S/P: Lundquist/Dorschner, move to recommend approval of a Comprehensive Plan Amendment re-guiding PID #’s 090292132001 & 080292140059 to Rural Single Family Sewered on the City’s Land Use Plan, Vote: 6-0, motion carried unanimously. Dorschner wanted to confirm that there was no Rural Single Family Sewered zoning. Handt stated that there was not, but this is just guiding it as such in the Comprehensive Plan. Hartley wanted to reinforce his concern from the standpoint of the Comprehensive Plan, they do not have the potential pollution issues under control for all of these properties that have individual septic systems and the inspection of them comes well after the fact that they have failed. Williams doesn’t disagree, but doesn’t feel that it will change anytime soon as he has heard the same discussion for 40 years. Business Item –Preliminary Plat and PUD Plans - Royal Golf Wensman started his presentation by stating that the Planning Commission approved the rezoning to GCC on 3/13/17 and tabled the approval for the Preliminary Plan and Preliminary PUD Plans. At the last meeting, the developer was proposing some changes to the NW neighborhood. They have withdrawn those changes at this time. The Planning Commission requested addition information on forest management, but the developer is no longer interested in doing that. The developer has indicated he will comply with the tree replacement requirements, but there is still dispute as to whether the project is a mixed use. Since 3/13, the VBWD has raised concerns regarding some of the infiltration basins. The developer is working through those issues and is confident 5 Lake Elmo Planning Commission Minutes; 3-27-17 there are adequate solutions that will not impact the plat. Staff has slightly modified the condition pertaining to VBWD approval. Staff added a missing condition that the green corridor in the NW neighborhood be a minimum of 100’ wide outside of the lot area. Right now there is one area that is shown at 84’ with one of the lot lines. Staff is recommending the same conditions with some corrections and additions. A correction to #15, correcting the Lots and Block it pertained to. Condition #20 pertains to the woodland management. It doesn’t hurt to keep that condition if the developer changes his mind, but it is up to the Planning Commission how to handle that. Condition #24 was reworded to make it clearer. #35 was added to capture the 100’ green corridor. #36, #37 & #38 are the 3 conditions added by the Planning Commission regarding the sidewalk along the South side of 20 th street and that there would be no street lights except at street intersections to meet the dark sky ordinance and to work with adjacent property owners to come up with screening that gets incorporated into the landscape plans. The recommended findings are the same with the addition of #9 that a significant amount of public testimony regarding that 20 th street is already dangerous without the additional traffic and the developer needs to explore ways to make the road safer. Staff is recommending approval with 38 conditions of approval and the 9 findings identified. Dorschner asked what the dispute is around mixed use. Wensman stated that the tree preservation plan has a provision that requires mitigation as well as landscape requirements for residential development. For commercial and mixed use developments there is an exception that all trees with the exception of ornamental trees may be counted towards tree replacement requirements. The developer is saying that this site is mixed use with the golf course being the commercial piece. They are arguing that it the case so that all of the replacement trees will count towards their landscaping requirements. Staff is saying that the golf course is the principle use; open space. It was a public facility in the past and it had an accessory commercial use, which is not the primary use. They will be creating a separate parcel for the more commercial site, and possibly that could be exempted, but exempting the whole golf course is not consistent with past practice and the City attorney does not support the mixed use interpretation. Wensman stated the difference would be a large cost to the developer in tree replacement or a significant loss of trees for the City. Staffs solution for this was the idea of forest management to better serve the development. The developer likes the tree preservation better because it is more quantifiable vs the forest management which is kind of a gray area. Rick Packer, Royal Golf, stated that the attorneys were discussing the mixed use concept and they had hoped that they could come to a compromise. They did not feel that the forest management was a compromise, but an exchange for the tree preservation requirement. The Royal Golf attorney opinion is that this development is mixed use. There is economic incentive that the City has provided to commercial development. There is currently no definition of mixed use in the City code. In the absence of a 6 Lake Elmo Planning Commission Minutes; 3-27-17 definition, those terms are supposed to be given their plan and ordinary meaning. The Royal Golf Community has 4 different types of uses on the property. There is residential, business services, food service and outdoor recreation. They feel that the golf course is clearly a commercial use. This is a wooded site vs a cornfield, so the number is really large. There are 8500 trees on this site, with about 3000 trees being removed. They are allowed to remove roughly 2500 trees or 30%. They are removing about 35% or 418 trees more than what is allowed. Based on the City code without the mixed use exemption, they would need to plant 3024 trees or 10 trees per lot. Packer states it would cost them $1.5 million dollars for trees alone. They had proposed 900 trees or 3 trees per lot. Packer stated that staff rejected that as there was no way for them to inspect them. They are planting 214 trees that are ornamental which do not count either. They feel that they legally qualify for a mixed use and should get the exemption. They were looking for some compromise that they did not get. Royal Golf is proposing to construct an off street trail in a location shown on the overhead vs a trail on 20th Street that has no shoulders. There is a significant grade change where the trail would need to go and a loss of trees. They would argue that it would be better served with adding a shoulder to the road that is wide enough to walk and bike on. Packer talked about the alternate Villa design and would like that to move forward to the City Council. There is one driveway that is in the sanitary sewer easement which is a concern to the city engineer. They can enter something into documents recorded against the property. Packer stated that this plan has one less unit than proposed with plat, but is essentially the same grading plan. Lundquist asked why the proposed sidewalk on 20th only goes just past the clubhouse. Packer stated that there are places that are very steep and would be very disruptive to that area. Williams asked why the City would not accept the widened shoulder or sidewalk within the ROW. Wensman stated that MSA standards would require the sidewalk to be located on the outer edge of the ROW. Larson asked what the status of the tree replacement is. Wensman stated that there is the landscape requirement and the street tree requirement. The City is going the mor e lenient interpretation, requiring landscaping based on the disturbed area calculation. Street trees will go in with the road when the improvement goes in. In terms of the development trees with 4 trees going in with the home, as long as the City has escrow to ensure the trees go in, the timing isn’t as important. There is a difference between the developer and the City of approximately 1000 trees. That difference hinges on the Mixed Use issue as the City and developer have failed to come to a compromise. Williams asked if they are opposed to any forest management in exchange for relief of the tree replacement. Packer stated that there is no compromise if it is dollar for dollar exchange they would not be interested. Williams stated that he is willing to relax the tree replacement provisions from 1000 to 500 in return for a program of buckthorn removal for 3 years after construction has started. Hartley thinks that it is problematic as it is not just the individual home owners. Dorschner stated that buckthorn is very 7 Lake Elmo Planning Commission Minutes; 3-27-17 difficult to manage and is good screening. Hartley feels that the City is better off having new trees vs a management plan based on the possible tree diseases. Emerson feels that the uses out there are mixed use and that is what they need to decide. Williams feels that they need to go with the City Attorney’s opinion on that issue, but also feels that there should be some relaxation of the number of trees with buckthorn removal. M/S/P: Williams/Lundquist, move to add an additional condition that the tree replacement requirement based on residential use be relaxed by 50% in return for the developer controlling buckthorn by cutting stems and treating the remaining stumps by either physical pulling or by herbicide application for a period of three years beyond the date for which construction begins for the adjacent phase, Vote: 4-2, motion carried with Hartley and Dorschner voting no. Wensman stated that this motion would replace condition #20 in the packet. Dorschner asked how many trees this would leave them to replace. Half would be around 500. Dorschner feels there would be more value in trees vs. the forest management. He feels the real issue is the mixed use interpretation vs. residential, but feels they need to go with the attorney’s opinion. Jim Felton talked about what they did for the wildlife corridor and what was required by the VBWD. His estimate of cost for what they have done is about 50K. Williams doesn’t believe there are any West Lakeland properties that they need to be concerned about in regards to screening. Packer stated that they have an agreement with the Homestead development. Williams feels that the City should allow the golf carts on the streets for the GCC. Wensman stated that a separate ordinance would be required that is not part of the zoning code. They could recommend that staff bring one forward. Hartley stated that personally he is not in favor of the golf carts because they are often driven irresponsibly and rules are not followed. Emerson doesn’t have a problem with golf carts and maybe an age limit could be put on it. Dorschner was in Arizona and many of the communities there have them. Larson stated that the golf carts would have destinations such as the clubhouse, restaurant, etc. Schroeder stated that they have looked at many ordinances in different cities and they address such things as age, speed, hours of operation, lights, etc. M/S/P: Williams/Dorschner, move to propose an additional finding #10 that the Planning Commission determines that it would be desirable to allow golf carts on the public streets within a golf course community, Vote: 5-1, motion carried, with Hartley voting no. Williams asked if the Fire Chief commented on the street names. Wensman stated that the Fire Chief does not like the new street naming policy, and is going to be taking the whole street naming policy back to the public safety committee. This street naming complies with the current ordinance. 8 Lake Elmo Planning Commission Minutes; 3-27-17 In regards to the street lights, the City Engineer stated that there is no requirement to have street lights in a development. Packer is wondering if they have addressed the Villa area. Handt stated that as of Friday, the developer was pulling that section, but tonight included it in the presentation. Wensman stated that one clear problem based on their limited review is the driveway with a storm pipe underneath it which will need to change. M/S/P: Williams/Dorschner, move to recommend condition #39 that staff reviews and approves the new plans presented tonight regarding the Villas and that the developer complies with all of the staff recommendations, Vote: 6-0, motion carried unanimously. M/S/P: Lundquist/Larson, move to recommend approval of the Preliminary Plat and Preliminary Planned Unit Development Plans for the Royal Golf Club at Lake Elmo with the 39 conditions based on the 10 findings identified in the staff report and amended by the Planning Commission, Vote: 6-0, motion carried unanimously. Business Item – Zoning Text Amendment – Village Low Density Residential Zoning Wensman started his presentation regarding the Village Low Density Residential Zoning. Since the last meeting, there were density ranges added, the impervious calculation was added to 35%, struck the maximum setback standard, allows free standing multi-family dwellings as a CUP to match the comprehensive plan, and clarified the setbacks for other residential uses. There was a desire at the last meeting to have a build to line incorporated into the VMX and the staff thinks that they have addressed that by the prevailing setback of the street to have consistency. If it is a new street, it can be decided at that time. Wensman went through some of the other standards. Williams asked about the garage standards and why that need to be called out specifically. Wensman thinks that it for existing homes that might want to build an additional garage. There was some information regarding tiny houses and if the City wants to alter its minimum home size. Wensman thinks more research needs to be done regarding this for the next meeting. Another consideration is would we want to have different standards for the urban vs rural areas. There was discussion if the Planning Commission thinks the VMDR zoning should just use the standards for LDR and have that reference made in the Comprehensive Plan. Hartley is wondering how the City determines in the VMX what is a permitted use and what requires a condition use permit. Wensman stated that there is not a straight criteria that determines if it is permitted vs a CUP. Typically the City makes uses conditional if it is perceived that the type of use could potentially create issues so the city wants to put conditions on the use. Williams stated that if there were 9 Lake Elmo Planning Commission Minutes; 3-27-17 recommendations of uses that should be permitted, the Commission could take up that discussion in the future. Business Item – Zoning Text Amendment – Solar Ordinance Wensman started his presentation regarding the solar ordinance. Some of the reasons for a solar ordinance are to protect neighbors from glare, that it meets imperious surface, area and size requirements and that there is a decommissioning plan. There is also a solar farm definition, which is not currently outlined in the Zoning Code as allowed permitted or condition primary use. Where should they be allowed as a primary use if anywhere? Some of the standards are that it must comply with accessory structure setback, height, lot coverage, etc. Should solar energy systems be exempt from certain standards in certain areas? Hartley is wondering if the City wants to add to the ordinance that an HOA can’t prohibit the use of solar panels. Wensman stated that would be unusual, but the City could put that restriction on. Currently solar farms are not allowed as the primary use anywhere, should they be? Staff is looking for any other additional standards that the Commission would like to include. Hartley thinks a large commercial installation is very different than a residential one. He also feels that in residential, if it is limited to the rooftop, that is different issue than if it takes up a whole back yard. Williams suggested a slightly different definition of solar farm from “wholesale sales” to “offsite customers”. Williams wants “off -grid systems” defined in the interconnection agreement section. Williams would like to eliminate “using a reflector to enhance solar production” from the reflectors section. Hartley stated that the commercial operations are probably the only ones to use reflectors. Williams is also confused about “screening to the North side of the solar array”. He thinks they need to look at that. Hartley suggested just striking the word north. Williams thinks that it needs to be stated that solar panels are considered impervious for calculations. Emerson doesn’t feel that the whole thing should be considered impervious. Williams feels that especially in commercial operations, you have compaction of the soils and it is no longer like a vacant field. There are also access roads and maintenance to consider. Wensman stated that it is creating a concentrated flow and runoff. Williams feels that it is easier for the City to manage and not inconsistent with the codes of other Cities if it is considered impervious. Hartley stated that maybe the total area could be calculated and 50% is considered impervious. Williams would like to add a provision that HOA’s and CIC’s are not allowed to prohibit solar systems. He is wondering if they should add solar systems as an incentive in the PUD bonus table. Williams asked if these systems would require a city building permit. Wensman stated that they would because of the footings. Hartley stated that screening and such would need to be reviewed by the City. Wensman stated that it might not be a building permit, but a zoning compliance review. Williams stated that there is a reference to building code in the code requirements section and it should say all rooftop 10 Lake Elmo Planning Commission Minutes; 3-27-17 or building integrated systems. Williams would like to add the words “and/or screened” to item #7 Visibility to be consistent with other rooftop structures. For storm water management, Williams would like to add “Watershed Districts requirements”.

Upcoming Meetings a. April 10, 2017 b. April 24, 2017 2. MAC CEP Report Commission Concerns Hartley would like to reinforce the idea that the meetings not be too long and that the Commission get out at a reasonable hour. If the meeting gets too long, they are not at their best. Dorchner wants to finalize the rural single family sewered. Wensman stated that the ordinance states that the rural single family should be predominately individual septic, but does not require it to be so. If they are designated in the comprehensive plan by the MUSA, it is allowed. Dorschner feels there should be different standard for when you are sewered and when you aren’t. Wensman will look at it more detail and report back. Williams is concerned that there has been nothing done as a City regarding form based code. He recognizes that it takes a long time, but it just keeps being pushed down the road. Wensman stated that through the Comp Plan amendment process, the vision will be reaffirmed. Meeting adjourned at 10:45 pm Respectfully submitted, Joan Ziertman Planning Program Assistant BUSINESS ITEM 5b STAFF REPORT DATE: APRIL 10, 2017 AGENDA ITEM: 5B – PUBLIC HEARING CASE #2016-59 TO: Planning Commission FROM: Emily Becker, Planner SUBMITTED BY: Zoning Text Amendment – Village Urban Districts REVIEWED BY: Stephen Wensman, Planning Director BACKGROUND: The Planning Commission has reviewed a proposed draft Village Urban Low Density (V-LDR) zoning district as well as minor amendments to the Village Mixed Use (VMX) District at its January 23, 2017, February 13, February 27, 2017, and March 27, 2017 meetings. ISSUE BEFORE THE COMMISSION: Staff respectfully requests that the Planning Commission hold a public hearing and recommend changes to and/or approval of the proposed draft ordinance of the Village Low Density Residential and minor amendments to the Village Mixed Use (VMX) District. PLANNING/ZONING ANALYSIS: Summary of Discussed Changes since the last Planning Commission meeting to Proposed Ordinance. The following provides changes and responses to Commission feedback provided from the last meeting at which the subject ordinance was discussed:  Multi-Family Not within a Mixed Use Development Added. There was question about if there was a definition for multi-family and for mixed use. Multi-family dwelling is defined in the Zoning Code as a building containing three or more dwelling units. The mixed use definition  Mixed Use Definition. The Commission asked that mixed use be defined. Staff was unable to find a very good example of mixed use to fit broadly within the Code. The VMX District states that more than one use is allowed on one parcel of land or in one building. Mixed use could mean a number of things: a mixture of uses in one building, one parcel, one development, one area, or one neighborhood. Staff does not recommend that Mixed Use be defined, as it could cause issues with interpretation elsewhere in the Code.  Additional Density Standards Added. Staff added language from the Comprehensive Plan Amendment approved in late 2015 that allows a higher density for senior congregate care facilities with services in the VMX to exceed listed density maximums with a range not to exceed 16 units per acre provided the facility can satisfy all zoning and applicable conditional use permit reviews.  Garage Setback. There was question as to why garages should be required to be setback at least 25 feet. This is to prevent cars parked in driveways from parking in the right-of-way. Garage setbacks were added to the Lot Dimension and Setback Requirements table in order to simply standards.  Standards for Village Medium Density Residential. There is still no Village Medium Density Residential Zoning District. The density that is set forth in the Comprehensive Plan for the Village Medium Density Residential land use is 2.5-4.99 units per acre. This is virtually the same density as Urban Low Density Residential (2.5-4 units per acre). Areas guided for Village Medium Density Residential may be zoned Urban Low Density to achieve the density for which 2 BUSINESS ITEM 5b – ACTION ITEM the area is guided. The reason for the creation of the Village Low Density Residential district is to create an urban residential zoning district which allows a density of 1.5-2.49 (the density the Comprehensive Plan designates for areas guided Village Low Density Residential), as there currently exists no zoning district that allows this.  Additional Setback Standards for County Roads Added. Staff has received requests from the county to add increased setback standards for county roads. Resultantly, Staff has recommended adding setback standards from county roads CSAH 14 and 17 at a minimum of 30 feet.  Single Family Homes in VMX. The Commission has expressed that they would like to see single family homes still allowed in the VMX District. o Zoning Code Language Currently. Currently, standards for the VMX district indicate that an existing single family home shall be considered a permitted, rather than non- conforming use, in the VMX zoning district. This language was derived from the Comprehensive Plan language outlined below. The Comprehensive Plan does not classify single-family homes as an allowed use in the VMX zoning district.  “[Uses in] VMX: Twin Home, Townhouse, Apartment/Condominium, Housing Above Retail”  “The existing residential neighborhoods within the Village Planning Area will [be] guided either as RS – Rural Single Family or as VMX – Village Mixed-Use with the intent of classifying all existing single family residential homes as permitted uses: o Language needs to be changed. This current language does not make legal sense. Either a use should be permitted or conditional use. Upon rezoning, a use may be made a legal non-conforming use, which would indicate that it could not be expanded. A legal non- conforming use may not be expanded through the variance process, as that would be considered a use variance, which is not allowed. o Single Family Detached Home as a Conditional Use in VMX. The Commission had mentioned that they may wish to see single family detached homes conditional uses in the VMX district as an option. Staff has drafted the proposed ordinance to read this way. However, the above should be considered regarding the Comprehensive Plan’s designated uses for the VMX district.  Minimum Lot Size Requirements for Single Family Detached Home in VMX. o Minimum Lot Size. Staff has estimated that the minimum lot size of single family homes within the VMX District is approximately 0.3 acres (13,068 sf). The Commission had expressed concern about lots with single family detached homes to subdivide. The current ordinance designates a minimum lot size of 5,000 sf for a single family detached home (even though it’s not an allowed new use). To address Commission concern, Staff is proposing that the minimum lot size be 9,000 sf, mirroring the minimum lot size standard of the proposed V-LDR standard. This would prevent a majority of the lots within this district to further subdivide, as only approximately eight of the single family residential lots guided for VMX would be able to further subdivide under this standard. o Minimum Lot Width. The current minimum lot width for single family homes within the VMX district is designated as 50 feet. However, it may make sense to increase this to 70 feet given the proposed increase minimum lot size of the district. It appears that very few single family lots within the Village have a lot width of as little as 50 feet, however it may affect some lots to increase the minimum to 70 feet. If the minimum lot size is increased, it may make sense to change the minimum lot width as well. Staff has changed the minimum lot width in the proposed ordinance but is looking for recommendation on this.  Conditional and Permitted Uses Currently Allowed in the VMX District. The Commission had expressed some concern over conditional and permitted uses currently designated as allowed 3 BUSINESS ITEM 5b – ACTION ITEM within the VMX zoning district. The Commission should specifically outline which uses are of concern and discuss. If additional standards are needed for specific uses, this should also be discussed.  New Housing Types Mixture Requirement. The following statement was added to standards for a single-family attached home in the VMX District. Staff added this standard, as it exists as standards for multi-family dwellings and two-family dwellings in the urban residential district. Staff has asked that the City Attorney review this language, as they believe it may not be legal to limit the type of housing one person can put in on a block just because someone had previously erected the same type of housing. o “New housing types should be introduced in limited quantities to increase diversity and housing choice, not to replace whole blocks of existing housing. Therefore, no more than 1/4 of the lineal frontage of a developed block may be redeveloped as two-family units, and no further two-family or higher density development is permitted once this threshold is reached. Lineal frontage shall be measured around the entire perimeter of the block.”  Veterinary Services. One comment from the Commission referenced that they may not wish to see veterinary services for large animals in the downtown area. Staff has added language that sets forth standards preventing this. The Commission should also keep in mind that further conditions can be placed during the conditional use permit process to help mitigate risks associated with certain uses.  House Size. The Commission did not specifically speak about the single family detached dwelling size regulation that was added to the VMX and V-LDR Zoning Districts. This standard remains unchanged as a result.  Question about General Site Design Considerations (154.504) vs. Development Standards for Specific Uses (154.505). The Commission had a question about why these were two separate sections. Section 154.504 sets forth general standards for all development within the Village District, whereas Section 154.505 sets forth general standards for specific uses. Findings. The Planning Commission drafted the following findings at its February 13, 2017 meeting: 1. That certain areas of the Old Village are guided for Urban Low Density Residential in the Land Use Plan of the Comprehensive Plan, which designates a density of 1.5-2.49 units per acre. 2. That there currently does not exist a Village Low Density Residential zoning district which has a density of 1.5-2.49 units per acre within the Zoning Code. 3. That the Village Low Density Residential zoning district is being proposed due to the imminence of the Gonyea West Development, which is expected to be proposed to be located within the Old Village in an area guided for Village Low Density Residential. 4. That the Planning Commission would be interested in exploring increased densities within the Old Village as an amendment to the Comprehensive Plan. RECOMMENDATION: Staff recommends that the Planning Commission hold a public hearing and provide feedback on or recommend approval of amendments to Article XIII: Village Mixed Use Districts, which add standards for the V-LDR Village Low Density Residential District and proposes minor changes to the VMX – Village Mixed Use District. If the Commission wishes to make recommendation at this time, the Commission may do so with the following motion: “Move to recommend adoption of Ord 08- , creating a Village Low Density Residential District and making minor amendments standards of the Village Mixed Use District.” 4 BUSINESS ITEM 5b – ACTION ITEM ATTACHMENTS: 1. Draft Ordinance Planning Commission Draft 4/10/2017 1 CITY OF LAKE ELMO COUNTY OF WASHINGTON STATE OF MINNESOTA ORDINANCE NO. 08-__ AN ORDINANCE AMENDING ARTICLE XIII: VILLAGE MIXED USE DISTRICT AND CREATING STANDARDS FOR A VILLAGE LOW DENSITY RESIDENTIAL ZONING DISTRICT SECTION 1. The City Council of the City of Lake Elmo hereby amends the Lake Elmo City Code Title XV: Land Usage; Chapter154: Zoning Code; Article XIII: Village Mixed Use District; to read the following: ARTICLE XIII: VILLAGE MIXED USE DISTRICTS § 154.500 PURPOSE AND DISTRICT DESCRIPTION (A) V-LDR Village Low Density Residential. The purpose of the V-LDR zoning district is to provide opportunity for lower density residential development within the Old Village and create a transition and connectivity between the heart of the Old Village and surrounding rural areas. Residential development within areas zoned V-LDR will occur at a density of 1.5-2.49 units per acre. (B) VMX – Village Mixed Use District. The purpose of the VMX district is to provide an area for compact, mixed use development made mutually compatible through a combination of careful planning and urban design and coordinated public and private investment. This district is intended to continue the traditional mixed use development that has occurred in the Village area by allowing retail, service, office, civic and public uses as well as residential units. The mixture of land uses within the district is essential to establishing the level of vitality and intensity needed to support retail and service uses. Development within areas zoned VMX will occur at a density of 6-10 units per acre. Senior congregate care facilities may exceed this density maximum with a range not to exceed a total of 16 units per acre, provided the facility can satisfy all zoning and applicable conditional use permit review criteria. The placement of building edges and treatment of building, parking, landscaping, and pedestrian spaces is essential to creating the pedestrian friendly environment envisioned for the VMX district. The standards in this chapter are intended to implement and effectuate the principles and relationships established in the Village Master Plan, which will be carried out through specific standards related to site planning, signage, architecture, building materials, and landscaping. Renovation and infill of traditional storefront-type buildings is encouraged, and parking standards may be waived to recognize the availability of on-street and shared parking facilities. § 154.501 PERMITTED AND CONDITIONAL USES Planning Commission Draft 4/10/2017 2 Table 11-1 lists all permitted and conditional uses allowed in the urban residential districts. “P” indicates a permitted use, “C” a conditional use. Uses not so indicated shall be considered prohibited. Cross-references listed in the table under “Standards” indicate the location within this Ordinance of specific development standards that apply to the listed use. A. Combinations of uses, Village Districts. The following use types may be combined on a single parcel: 1. Principal and accessory uses may be combined on a single parcel. 2. A principal and secondary dwelling unit may be combined according to the standards of Section 155.137 154.454 (C). B. Combination of uses, VMX District. 1. Single-family attached or multi-family complexes designed for rental or condominium occupancy, since these typically include multiple units and buildings on a single parcel. 2. Other permitted or conditional uses allowed within the district may be combined on a single parcel, provided that a unified and integrated site plan is approved. The entire development must be approved as a conditional use. 3. A mixed-use building that combines permitted or conditionally permitted residential, service, retail and civic uses may be developed meeting the form standards of this Article. Office or studio uses on upper stories are encouraged.

The Commission wanted to further research into the minimum house square footage requirements allowed in all the zoning districts and suggested looking at the zoning codes for progressive cities, neighboring cities and a few similar cities in the west metro. Business Item – Zoning Text Amendment – Planned Unit Development Zoning Planning Director Wensman introduced draft changes to the PUD ordinance. He suggested the purpose to the changes was to add the recently approved OP PUD process to the Article I PUD regulations. The other primary change was to eliminate the size requirement for commercial PUDs and to allow the Planning Director to waive the Sketch Plan requirement for small commercial PUDs when they meet the identified objectives in Section 154.751. Wensman also mentioned that Consulting Planner Gozola had reviewed the draft and offered some additional suggested changes. Wensman stated he will review some of Gozolas suggestions and will incorporate them into a future draft amendment. Commissioner Williams wanted to revisit section 154.751, Identified Objectives. He felt the requirement that one or more of them needing to be met was too easy for developers. It was suggested that Planning staff research what other cities do for establishing a basis for allowing PUDs. Commissioner Hartley suggested that 154.752 C and D be reworded to something like 120% increase from the underlying zoning requirements. Commissioner Williams was supportive of the draft changes to the minimum requirements, but suggested some rewording. Commissioner Hartley wanted 154.753 B to include public trails. The Commission discussed potential changes to the point system in Table 16-2 and wanted to revisit this. It was felt that Trails were a requirement already if part of a comprehensive trail plan and that otherwise the City should not award points for them. Business Item – Zoning Text Amendment – Solar Ordinance Discussion Planning Director Wensman introduced the Solar Ordinance discussion asking the Commissioners what they wanted to see changed with the City’s ordinance. Commissioner Dorschner wanted to be sure the ordinance protected neighbors from glare, etc. related to solar facilities. Commissioner Larson also stressed that safety was a concern. 4 Lake Elmo Planning Commission Minutes; 2-27-17 Commissioner Williams thought the ordinance should address impervious surface requirements. Williams also felt the City should be less concerned with the amount of energy that can produced and more concerned about the area or size requirements and the districts in which the facilities should be located. Director Wensman offered that he would review the city’s ordinance against other ordinances to create a draft ordinance that takes into consideration the Commissions’ concerns along with items generally addressed in other ordinances for future discussion. City Council Updates – February 21, 2017 Meeting i) OP-Alt Zoning District Repeal – passed ii) Shoreland Management Overlay Ordinance Amendment – failed and tabled to next meeting iii) ZMA and CUP for 3549 Lake Elmo Ave - passed Staff Updates 1. Upcoming Meetings a. March 13, 2017 Planning Director Wensman informed the Commission that the Royal Golf zoning map amendment and preliminary plat and preliminary PUD, Inwood 5th final plat and PUD and Lakewood Crossing 2nd Concept PUD public hearings will be held. b. March 27, 2017 Planning Director Wensman thought that Easton Village 2 nd Addition and Hidden Meadows 2nd Addition final plat might be reviewed at this meeting along with business items for future ordinance amendments. Commission Concerns Commissioner Dodson asked to review the engineering standards for street lighting. Commissioners Dorschner and Hartley requested updated zoning maps for their zoning notebooks. Meeting adjourned at 9:45 pm Respectfully submitted, Joan Ziertman Planning Program Assistant STAFF REPORT DATE: 4/10/2017 BUSINESS ITEM #: 5a MOTION TO: Planning Commission FROM: Emily Becker, City Planner AGENDA ITEM: Solar Energy Ordinance REVIEWED BY: Stephen Wensman, Planning Director BACKGROUND: The creation of a solar garden/solar power ordinance is an item on the 2017 Planning Commission Work Plan. The Planning Commission reviewed a draft ordinance at its March 27, 2017 meeting. Staff has amended the proposed ordinance for the Planning Commission’s review. ISSUE BEFORE COMMISSION: The Planning Commission is being asked to clarify what should be included in the requested solar garden/solar power ordinance. PROPOSAL DETAILS/ANALYSIS: Exemptions. The Planning Commission may wish to consider certain exemptions for the requirement that solar energy systems adhere to the lot size and dimension standards of the zoning district in which the solar energy system is located. The average size of an “off-the-shelf” solar panel is approximately 1 square meter (approximately ten square feet). However, there are smaller solar panels available, and requiring that such solar panels meet the accessory structure setback requirements of a zoning district may be unnecessary. For example, the City had recently received an inquiry about installing a 13.2” X 11” solar panel to provide exterior lighting to a sign. Because the Current code does not provide exemptions, this solar panel would need to adhere to the minimum setback requirements of the zoning district in which the solar panel is being proposed. The Commission may wish to consider adding an exemption to these requirements, based on the size of the solar panel. Staff has proposed an exemption size of six square feet or less, but the Commission may wish to consider a different size for exemptions. Different Standards for Rooftop vs. Landscape. The Commission wished to designate different standards for rooftop vs. ground solar energy systems. Language was added to clarify different standards for rooftop and ground-mount solar energy systems. Standards for Solar Farms. The proposed ordinance sets forth standards for solar farms. These standards would set forth specifications for solar farms as a principal use within a zoning district. These standards Planning Commission Meeting 4/10/2017 Business Item #5a Page 2 would be specified in the Article of the zoning district in which solar farms would be allowed. Staff is requesting that the Planning Commission consider if solar farms should be allowed as a conditional primary use within a zoning district that currently exists in the city and to consider which zoning district that should be. Defining Off-Grid Systems. The previous ordinance exempted off-grid systems from being required to have an interconnection agreement. The Commission asked for a definition of off-grid. Staff revised the proposed ordinance to provide further clarification. Additional Clarification for Impervious Surface. Staff added language to further clarify what would be considered impervious surface for a solar energy system. This language was taken directly from the model ordinance. Reflectors. The Planning Commission suggested that the language in the proposed ordinance should be amended to state that glare should be minimized from any solar energy system rather than stating that glare shall be minimized from any solar energy system using reflectors. Staff has amended the language as such. Restrictions from Homeowner’s Association. The Commission had requested that the solar energy systems ordinance place restrictions on homeowner’s associations being able to forbid the installation of solar energy systems or create design standards that effectively preclude solar energy installations. This language has been added to the proposed ordinance. Tax Status of Solar Farms. The Commission had questioned what the tax status of solar farms would be. The City Assessor was contacted and stated that the land on which a solar farm in Scandia is located is taxed commercially. FISCAL IMPACT: None. OPTIONS: The Commission may wish to:  Specify desired amendments or additions to the Zoning Code regarding solar garden/solar power ordinance.  Not recommend amending current standards or adding new ones. ATTACHMENTS:  Draft Ordinance 1 CITY OF LAKE ELMO COUNTY OF WASHINGTON STATE OF MINNESOTA ORDINANCE NO. 08-___ AN ORDINANCE AMENDING THE LAKE ELMO CITY CODE OF ORDINANCES BY ADDING ADDITIONAL STANDARDS FOR SOLAR ENERGY SYSTEMS.

Ground-Mount Solar Energy Systems. a. Ground-mount energy systems are permitted accessory uses in all districts where buildings are permitted. b. A solar structure Ground-mount energy systems must comply with all accessory setback, height and lot coverage restrictions unless otherwise stated herein or a variance is granted and shall not encroach on any City easement unless an easement encroachment agreement approved by the Planning Director or his/her designee after review and approval from the City Engineer or his/her designee has been executed. A certificate of zoning compliance is required for all solar energy systems unless a conditional use permit is required as stated herein. Commented [EB1]: “Solar structure” is not defined in the code. “Solar Energy System” is now defined, and so was kept. “Solar energy systems” is sufficient to meet the intent of what is trying to be said here. 2 i. The collector surface of a ground-mount system and any foundation, compacted soil, or other component of the solar installation that rests on the ground is considered impervious surface. Vegetated ground under the collector surface can be used to mitigate stormwater runoff. c. Exemptions. Solar energy systems of a size of six square feet or less may be exempt from zoning district setback requirements. 3. Interconnection Agreement. All electric solar energy systems that are connected to the electric distribution or transmission system through the existing service of the primary use on the site shall obtain an interconnection agreement with the electric utility in whose service territory the system is located. Solar energy systems connected directly to the distribution or transmission system must obtain an interconnection agreement with the interconnecting electric utility. Systems that are not directly connected to the grid or not connected to the electric system of a building that is connected to the gird are exempt from this requirement. 4. Glare. Glare produced from any solar energy system shall be minimized from affecting adjacent or nearby properties. Measures to minimize glare include selective placement of the system, screening of the solar array, modifying the orientation of the system, reducing use of the reflector system, or other remedies that limit glare. a. Mirror Reflecting Designed Solar Energy Systems. Mirror reflecting designed solar energy systems are permitted only on properties with five (5) acres or larger. A conditional use permit is required and more restrictive setback standards may be required upon review of the conditional use permit. 5. Code Requirements.

BACKGROUND: On a periodic basis, the City’s Landscape Design Standard Details and Specifications are updated and approved by the City Council. As part of that process it was requested that the Planning Commission review them and make a recommendation to the City Council. This year, the landscaping and irrigation design standard details and specifications, have been removed from the Engineering Standards and these have been updated and incorporated into their own freestanding set of standard details and specifications. ISSUE BEFORE THE COMMISSION: To review the Landscaping Design Standard Details and Specifications and provide a recommendation to the City Council. PROPOSAL DETAILS/ANALYSIS: Landscape Standards (900 series). The new series include updated details for deciduous, coniferous trees and shrubs for flat and sloped site planting. The tree protection detail was also moved into the landscape standards. The landscape standards also include required and recommended details for landscape irrigation. The required irrigation details include the water service and controller details that illustrate the required connections to Municipal Water consistent with City Council’s direction in 2016 when reviewing and adopting the irrigation standards. The recommended details illustrate best practices in landscape irrigation and these details are taken from the 5th Street project, where irrigation was required. All the irrigation standard details refer to updated irrigation specifications. Other improvements to the details include:  To be current with MN Department of Transportation Standard Specifications for Construction 2016 Edition;  To be current with the latest edition of American Standard for Nursery Stock (ANSI Z60.1); Planning Commission Meeting 4/10/17 Business item #5b Page 2  To clarify and provide additional guidance on incorrect planting practices that have been observed from time on time projects within in the City specifically on City owned property / right of way;  Provide guidance within the irrigation specification and details to help further protect the City’s potable water resources; and  To be current with updated technology advances within the irrigation industry specifically in the areas of energy efficiency, water conservation, improved watering that coincides with better plant health and increased sustainability of the irrigation products and systems supplied. FISCAL IMPACT: None RECOMMENDATION: Staff recommends that the Planning Commission recommend approval of the Landscaping Design Standard Details and Specifications with the following motion: “Move to recommend approval of the Landscaping Design Standard Details and Specifications.” ATTACHMENTS:  Landscaping Standard Details and Specifications STAFF REPORT PLANNING COMMISSION DATE: 04/10/2017 ITEM #: 5b AGENDA ITEM: Engineering Design and Construction Standards Manual – March 2017 Revisions SUBMITTED BY: Jack Griffin, City Engineer REVIEWED BY: Kristina Handt, City Administrator Rob Weldon, Public Works Director Stephen Wensman, Planning Director Chad Isakson, Assistance City Engineer BACKGROUND: The City has prepared and maintains engineering design standards, standard specifications, and standard details for public infrastructure within the City, including streets, sanitary sewer, watermain, storm water facilities, right-of-way management and boulevard layout. This information is compiled into an Engineering Design and Construction Standards Manual for use by staff and the development community. The latest version of the Manual is dated February 2015. The standards have been established to set minimum requirements to be met for all public infrastructure projects in the City with the intent of constructing consistent and compatible infrastructure systems throughout the community; to clearly communicate with the development community these minimum expectations and requirements; and to expedite plan design, preparation and City plan review and approvals. The engineering design standards and guidelines have been established to address the most common project elements and are to be used in conjunction with the requirements set forth by applicable codes, laws and ordinances, recognized industry standards, good engineering practice and specific project needs. Omission of reference in these standards and guidelines does not relieve responsibility for compliance with these requirements. In addition, the provisions of these standards and guidelines are not intended to prohibit the use of alternative systems, methods or components. Professional engineering judgement and ingenuity is encouraged to adapt to specific project needs. However, varying from the standards and guidelines will only be permitted with the approval of the City Engineer, after performing due diligence to ensure the design is equivalent or superior to the prescribed elements of the guideline. ISSUE BEFORE THE COMMISSION: Staff respectfully requests that the Planning Commission review and recommend approval of the March 2017 revisions to the Engineering Design and Construction Standards Manual. PROPOSAL DETAILS/ANALYSIS: The Engineering Design and Construction Standards Manual is a living document that is reviewed and modified from time to time by the City Engineering team to adapt pro-actively to changing conditions so as to remain current, address best practices and extract additional economic value and performance as needed. Changes are often based on recommendations from Planning, Public Works or other City staff, the development community, and other stakeholders.
