PUBLIC COMMENTS
Zach Miller, 988 Kay Avenue, presented a petition to the City Council requesting that the City undertake
the soundwall application process through MnDOT. The petition is signed by 50 residents in the
neighborhood adjacent to 35E south, where it exits to 62. He stated that the residents are asking that the
City submit an application, as the window for applications is currently open. He believed that the noise
level from those two roadways is considerably higher than it was two or three years ago when the last
study was completed. He recognized that it may not be approved this year, but perhaps it would move up
on the list and the improvement could be awarded in a future year.
Valerie Namen, 964 Kay Avenue, also spoke about her desire for the City to pursue a soundwall. She
stated that she is a lifelong Mendota Heights resident and explained that she can see 11 lanes of traffic
from her property and spoke about the increase in traffic and noise that has occurred in the 30 years she
has lived at her current home. She commented on the impact the noise has on the enjoyment of her
property and noted that the natural screening that has been removed only increased the impact on residents.

She believed that a new sound study would provide additional details as the impact has increased in recent
years.
Joe Foley, 1975 Walsh Lane, also spoke in favor of the noise wall. He stated that they moved to Mendota
Heights one year ago and have noticed an increase in the impacts after the natural screening was removed.
He stated that he is an engineer and provided three suggestions that the City could pursue: to submit a new
project proposal to MnDOT with a wall starting at Victoria Road to Marie Avenue; to keep in mind that
the soundwall could be made of wood rather than concrete, as wood has a lower cost; and to consider that
the height of the wall does not need to be 20 feet, noting that a ten foot wall would be appropriate for most
of the span. He believed that those ideas would provide a barrier that is also cost efficient.
Andrew Katz, 1960 Walsh Lane, stated that he also supports reviewing the issue of a sound wall. He
stated that he and his neighbors have also been in contact with MnDOT. He stated that there are three
walls proposed that are being reviewed for Mendota Heights and the two walls that would be adjacent to
this area are ranked 97 and 103 on the MnDOT list of priorities. He stated that after speaking with MnDOT
the sound walls are designed for the type of housing products and a wall that long would not be feasible
as an access gap would be needed for maintenance. He stated that perhaps this could be one project with
a shorter distance. He stated that if chosen, the City would be responsible for ten percent of the cost and
hoped that the Council could begin to budget for that cost should the project be chosen to move forward.

PUBLIC HEARING
Page 4 of 177
September 17, 2024 Mendota Heights City Council Page 3 of 14
A) RESOLUTION 2024-49 ORDERING OF IMPROVEMENTS FOR THE FRIENDLY HILLS
NEIGHBORHOOD IMPROVEMENTS
Assistant City Engineer Lucas Ritchie explained that the Council was being asked to consider adoption of
Resolution 2024-49 ordering Street Improvement Project for the Friendly Hills Neighborhood.
Luke Moren, Kimley-Horn, provided a brief background on the project area and details and then reviewed
the resident input that has been received through the public engagement process.
Councilor Paper asked for more details on sacrificial anode.
Mr. Moren explained that soils can corrode the iron pipe over time. He stated that they use large sacks of
magnesium and those chemicals that would typically react with the pipe will instead react with those
sacks. He confirmed that it is external of the pipe.
Councilor Paper asked if there is a cost estimate for the Decorah trail construction if there was one built.
Mr. Moren confirmed that was included in the feasibility study.
Councilor Paper asked if the trails within Friendly Hills Park will be replaced as part of the project.
Assistant City Engineer Lucas Ritchie confirmed that those trails are included, as well as to the south to
the Apache neighborhood.
Councilor Paper asked if the parking lot is being included in the project.
Assistant City Engineer Lucas Ritchie confirmed that the parking bays along Decorah are included.
Councilor Mazzitello referenced the Decorah trail section that is not included as presented tonight and
asked if that connects two existing trail segments and whether there is another route around Decorah for
those trails to take.
Mr. Moren stated that there is not a direct route around and confirmed that the segment would connect
two existing segments. He stated that pedestrians are currently walking on the shoulder for that segment
of Decorah.
Mayor Levine referenced the definition of unit and asked for clarification on lots that are smaller.
Assistant City Engineer Lucas Ritchie replied that applies specifically to City owned parcels, such as
Friendly Hills Park. He stated that residential properties would each have the same assessment amount,
regardless of the size of the parcel or property value.
Councilor Mazzitello moved to open the public hearing.
Councilor Paper seconded the motion.
Ayes: 4
Nays: 0

Dave Jacobson, 728 Mohican Court, asked if the $7,700 assessment would be due at once or spread over
multiple years. He asked what the red dots on the map mean.
Mayor Levine commented that those are spots where digging will occur for the magnesium drops that
were just discussed.
John Maczko, 751 Cheyenne Lane, stated that he agrees that the streets require maintenance, noting that
at 20 years an overlay is recommended rather than a full depth reclamation. He stated that the roadways
were reconstructed in 1995, therefore they are beyond the 20 years, but typically streets last longer than
the estimates of engineers. He stated that the pavement ratings were stated at 25 to 50 but believed that
the streets within the Friendly Hills area are not within that range. He did not disagree that improvement
is needed, but believed that an overlay could achieve that desired goal. He stated that catch basin repairs
are a standard process during an overlay as well. He stated that for pavement conditions of 35 to 55
local maintenance and an overlay is recommended. He stated that the cost savings would be significant
if the overlay method were chosen, reducing the cost by over $2,000,000. He asked that the Council
consider the overlay rather than the full depth reclamation. He recognized that the reclamation may be
needed where watermain work is required, but most of the project area could benefit from just an
overlay.
Kelly Veazie, 2142 Fox, agreed with the previous speaker that while the roads need fixing, they are not
that bad. She commented that there are areas where the water pipes are being redone but a majority of
the project area will not have that work done and would therefore not require the same level of work.
She commented that it does not make sense to put a new road down when the pipes underneath need
work and suggested that the City better coordinate with Saint Paul Regional Water Supply (SPRWS).
Stacy Styles, 2188 Aztec Lane, asked for logistical information on parking during the project. She
asked if there would be concern of foundations shifting or dirty water coming into homes with the
watermain work being done.
Steve Waters, 747 Decorah Lane, stated that he has spoken with a number of neighbors on the street,
and they do not want the trail/bike lane and would prefer to keep the off-street parking for their homes.
Allen Olson, 2153 Fox Place, also asked why a new road would be placed over bad watermains. He
referenced the sacrificial anodes, stating that they are not a fix or a repair. He stated that this may
provide a delay but there is not a fix. He stated that there have been blowouts, and they cannot reverse
the problem and instead need to address it. He stated that the value of the anodes is limited and would
prefer to wait for the water pipes to be replaced before there is a new road.
Anna Argent, 752 Cheyenne Lane, asked if the residents would receive updates on the project progress
and water shutoffs to allow the residents to plan for those things.
Michele Kadrie, 697 Decorah Lane, asked about the anticipated length of the project segments
(2025/2026) if approved. She asked if there is a cost for just the overlay.
Page 6 of 177
September 17, 2024 Mendota Heights City Council Page 5 of 14
Eric Kruger, 720 Decorah Lane, thanked the Council for hearing the residents on Decorah and their
desire to not have a trail segment.
There being no one further coming forward to speak, Councilor Mazzitello moved to close the public
hearing.
Councilor Paper seconded the motion.
Ayes: 4
Nays: 0
Mayor Levine thanked all the residents for their input tonight.
Assistant City Engineer Lucas Ritchie stated that each phase of the project would be completed within
the project year, during the May to October timeframe. He stated that they will look at alternative
detours as some of the work will limit access to homes. He stated that they would phase replacement
efforts to ensure there would still be access during construction. He stated that the watermain method of
replacement will be a bursting method, which will not require open trench. He stated that they will work
with property owners when they work on service connections which may require alternate parking
within one block or so.
Mr. Moren commented that the limited access would be during the hours of 7 a.m. to 7 p.m., which
would allow residents to leave their home prior to the start of work that day and get back into their
driveways after work has completed for the day. He stated that they will have their traffic management
plan at the spring open house for the public.
Assistant City Engineer Lucas Ritchie stated that a project page is created for each street project and
reviewed the details that would be posted daily. He believed that SPRWS also has an automated service
that makes residents aware of water shutoffs or temporary water connections. He stated that he has not
been involved in any projects which have involved foundation shifting or anything of those concerns.
He stated that the service connections are two to three feet off the property line and the vibration would
be limited to the road itself and within the right-of-way.
Mayor Levine commented that she wanted to be clear that the Decorah trail segment has not been
included in the project as the Council heard the comments from the residents along that path of the road
stating that they did not want that. She referenced the comments received about the sacrificial anode,
recognizing that is a delay but that it should last for 20 years.
Assistant City Engineer Lucas Ritchie stated that a member of SPRWS is present that can provide more
details on the sacrificial anode. He stated that they targeted the area with the highest break rate for that
treatment. He stated that section is proposed to be abandoned.
Luke Sandstrom, SPRWS, stated that 20 years is the industry standards for sacrificial anodes. He agreed
that this will not fix the pipe but buys more time for a future project. He stated that Fox Place has a
lower risk than Aztec and three of the breaks have occurred on a section of line that will be completely
removed with this project.

Councilor Mazzitello asked if it would be worthwhile to complete a mill and overlay on the streets not
being excavated for utility replacement.
Assistant City Engineer Lucas Ritchie replied that would be an option. He stated that the City tries to
focus on doing a complete neighborhood when doing repairs. He stated that if they do different repairs
on different segments in a neighborhood that will change the maintenance cycle. He stated that they
prefer to have the streets within a neighborhood on the same maintenance cycle and if an overlay were
done in a section of the neighborhood, those streets would be due again for repair in about 10 years. He
stated that the sacrificial anodes are placed at 200-foot increments and will also require excavation,
which would also allow for moisture to seep in and cause additional cracking with just an overlay. He
stated that the pavement lifecycle is roughly 20 years for this type of improvement and at that time they
would reassess the watermain system as well.
Mayor Levine used the scenario that a new sewer is needed on Fox in 20 years and asked the type of
road repair that would be needed with that improvement.
Assistant City Engineer Lucas Ritchie replied that typically when you replace utilities to that caliber,
they would not be looking at an overlay because of the amount of pavement that would need to be
removed. He stated that it does not make sense to have an overlay when utility replacement is being
completed.
Mayor Levine asked staff to reply to the ratings of the roads provided by staff versus the opinion of Mr.
Maczko.
Assistant City Engineer Lucas Ritchie stated that every person will have their own opinion on the
pavement condition index (PCI). He stated that they are proposing a project at the 30-year lifecycle and
the threshold for an overlay is PCI of 60 to 70. He stated that although the condition may not be as low
as 25, he would argue that it is also not 60. He provided details on the options residents have for
assessment payment, noting that the assessment would go onto the tax rolls for 2027 with a ten-year
repayment period. He stated that there would be an assessment hearing in October of 2026 for both
project areas and residents could then make a full payment within 30 days to avoid paying interest and
avoid the assessment from going onto the tax roll. He confirmed that a partial payment could also be
made to reduce the amount that goes onto the tax roll.
Mayor Levine asked the cost of an overlay versus the full reclamation.
Assistant City Engineer Lucas Ritchie stated that full cost has not been estimated. He stated that while
generally an overlay is cheaper, that cost does not take into account the utility work that is needed. He
explained that would also only buy ten years.
Mr. Maczko disagreed with the PCI rating suggested an overlay, noting that the rating could go as low
as 35 to still receive benefit from a mill and overlay.
Councilor Paper asked if there is a metric that is used to determine the number of watermain breaks that
would trigger full replacement.
Page 8 of 177
September 17, 2024 Mendota Heights City Council Page 7 of 14
Mr. Sandstorm replied that there is a calculation used, noting that while breaks are a factor they are not
the only element used in that determination. He explained that the pipe is not always bad when there is
a break and provided some examples of other things that cause those breaks.
Councilor Paper asked if there was any discussion about a realignment of Decorah and Wagon Wheel.
Assistant City Engineer Lucas Ritchie replied that was not considered for this project but is shown in the
Capital Improvement Plan (CIP) for 2030. He stated that project will have a different set of
ramifications, and they will need to work with the State on that project.
Councilor Mazzitello stated that this was the first subdivision done in 1995 under the current street
maintenance system. He stated that at that time it was decided that the watermain would not be
replaced. He stated that part of the reason the street ratings in some sections of this project are so low is
because of the watermain issues and breaks that have occurred. He asked for and received information
on sections of road that would not have utility work completed. He stated that in 1995 the decision was
made not to replace the watermain which is causing the road to fail and need replacement earlier than
typical. He stated that in 20 years they will come back and replace the watermain and asked if they are
making the same mistake that was made previously and putting too much money into the road repair
when they know it will be dug up in 20 years. He stated that in the sections where watermain is being
replaced, the reclamation does make sense.
Assistant City Engineer Lucas Ritchie commented that is a possibility and there is also a possibility that
SPRWS does not have the funds to complete that replacement in 20 years.
Mr. Moren stated that there are segments of the project area that does not have the red dots because they
do not have the same types of pipe.
Councilor Mazzitello asked that an estimated cost savings be shown in the final design that would
provide overlay services in the areas of the project that do not require extensive utility work.
Assistant City Engineer Lucas Ritchie confirmed that could be provided.
Mayor Levine asked if cost could also be shown for the replacement of the pipes and whether that is a
cost the City could absorb.
Councilor Mazzitello commented that the City’s water system was deeded to SPRWS in 2016 for this
very purpose. He stated that they spent years developing the details of that agreement, and one of those
details was to sync the replacement of infrastructure with SPRWS. He stated that this is a very large
area and SPRWS is aware of the condition of the infrastructure, noting that while the sacrificial anodes
will buy time, that repair will be needed in the future. He stated that he would not want to spend
unnecessary funds and resources on something they know will need to be excavated in the future. He
stated that is why he requested to see the cost details for a mill and overlay on the sections of the project
that do not require digging to depth.
Mayor Levine recognized the comment that they do not want to spend more money than necessary when
future repairs will be needed.

September 17, 2024 Mendota Heights City Council Page 8 of 14
Councilor Lorberbaum asked what the Council is being asked to do tonight.
Assistant City Engineer Lucas Ritchie explained that the Council is being asked to order the
improvement project, which would move staff into the design phase of the project with actual costs
based on engineer’s estimates. He stated that they would then come back in late January/early February
to receive approval of the plans and specifications and receive authorization to go out for bid. He stated
that there will be extra design time needed in order to provide both scenarios, but also recognized that
there is not much of a difference between the plan set for the project as proposed and with the method
proposed by Councilor Mazzitello.
Councilor Lorberbaum summarized that this is simply taking the next step to move forward with
designing the project and those plans would still be reviewed and approved by the City Council.
Councilor Lorberbaum moved to approve RESOLUTION 2024-49 ORDERING OF IMPROVEMENT
PROJECT FOR THE FRIENDLY HILLS NEIGHBORHOOD IMPROVEMENT PROJECT (PROJECT
#202407), WITH DIRECTION FOR STAFF TO PROVIDE COMPARATIVE COST ESTIMATES OF
THE FULL RECLAMATION AND MILL AND OVERLAY FOR THE PROJECT AREAS NOT
RECEIVING EXTENSIVE UTILITY WORK/EXCAVATION.
Councilor Mazzitello seconded the motion.
Ayes: 4
Nays: 0
NEW AND UNFINISHED BUSINESS
A) CONSIDER APPROVAL OF ORDINANCE 592, AMENDING TITLE 12: ZONING OF THE
CITY CODE (ZONING CODE UPDATE PROJECT); AND CONSIDER APPROVAL OF
ORDINANCE NO. 593, CREATING TITLE 15: ENVIRONMENTAL STANDARDS OF THE CITY
CODE; AUTHORIZE PUBLICATION OF SUMMARY ORDINANCES
Planning Consultant Jennifer Haskamp explained that the Council was being asked to consider approval
of Ordinance 592, amending Title 12: Zoning of the City Code (Zoning Code Update Project); and
consider approval of Ordinance No. 593, creating Title 15: Environmental Standards of the City Code and
to authorize publication of summary ordinances.
Councilor Paper referenced a section of Chapter 12 related to wireless antennas and asked if this would
help to support the coverage that is needed.
Planning Consultant Jennifer Haskamp replied that the goal with the revised language is to state that there
are preferred locations, but the City would entertain secondary locations. She stated that the provider
would need to demonstrate that colocation is not possible and if a new tower is built, colocation would
need to be an option.
Councilor Mazzitello referenced the section related to PUDs, specifically amendments to the final
development plan and asked if the zoning amendment process would include the concept review.
Page 10 of 177
September 17, 2024 Mendota Heights City Council Page 9 of 14
Planning Consultant Jennifer Haskamp stated that the zoning would be amended, as the PUD would
function as a zoning district. She stated that the PUD process would still be followed for an amendment.
Councilor Mazzitello referenced the definitions, noting the definitions for public street, private street, and
street. He asked if the third definition is needed.
Planning Consultant Jennifer Haskamp replied that the definition for street is not needed.
Councilor Mazzitello referenced the definition of public street and asked if developed should be used
instead be constructed.
Planning Consultant Jennifer Haskamp agreed with that change.
Councilor Mazzitello referenced the R-1 standards table, noting recent requests for patio or deck
expansions. He stated that none of those requests exceeded 35 percent and therefore did not believe the
allowance for up to 50 percent with best management practices (BMP) is needed. He suggested that
remain for R-2 or above and leave R-1 at 35 percent or a variance.
Mayor Levine recalled that the Council had this discussion and believed that Councilor Lorberbaum also
agreed with Councilor Mazzitello. She used the scenario that a homeowner is already at 40 percent and
wants to put in a new driveway and asked what would happen.
Planning Consultant Jennifer Haskamp commented that replacing in kind would be allowed but if there
were any expansion, a variance would be needed.
Mayor Levine commented that she now recalls that there was discussion about a swimming pool, which
would exceed the 35 percent.
Councilor Mazzitello stated that his mind was changed by a recent swimming pool request, where the lot
stayed under the 35 percent by using pervious pavers around the pool. He stated that at the worksession
they had discussed allowing this provision for one year and then reviewing to see how it goes.
Councilor Lorberbaum commented that if the BMP option is included, that is providing residents
flexibility, and the Council needs to instead decide what it wants. She stated that they can still review
after one year and would prefer to stay stricter.
Mayor Levine confirmed the consensus of the Council to make the change to remove the BMP provision.
Councilor Lorberbaum thanked Planning Consultant Jennifer Haskamp noting that these have been a long
two years and acknowledged her work.
Councilor Mazzitello moved to adopt ORDINANCE NO. 592, APPROVING THE PROPOSED
AMENDMENTS TO TITLE 12: ZONING AND CORRESPONDING AMENDMENTS TO THE
ZONING MAP, TO BE PLACED INTO EFFECT ON JANUARY 1, 2024 AND TO AUTHORIZE
PUBLICATION OF A SUMMARY ORDINANCE AND TO ADOPT ORDINANCE NO. 593,
APPROVING THE CREATION OF TITLE 15: ENVIRONMENTAL STANDARDS, TO BE PLACED
Page 11 of 177
September 17, 2024 Mendota Heights City Council Page 10 of 14
INTO EFFECT ON JANUARY 1, 2025, AND TO AUTHORIZE A PUBLICATION OF A SUMMARY
ORDINANCE.
Councilor Lorberbaum seconded the motion.
Further discussion: Councilor Mazzitello stated that the motion is made incorporating the verbal changes
that were discussed prior to the motion.
Mayor Levine acknowledged the work of the Planning Commission, members of the public, members of
staff, and Planning Consultant Jennifer Haskamp who were all involved in this long process.
Ayes: 4
Nays: 0
B) CONSIDER APPROVAL OF ORDINANCE NO. 591, AMENDING TITLE 3: BUSINESS AND
LICENSE REGULATIONS TO CREATE A SHORT TERM RENTAL ORDINANCE AND LICENSE
PROCESS; AUTHORIZE PUBLICATION OF SUMMARY ORDINANCE; AND, CONSIDER
APPROVAL OF ORDINANCE NO. 594, AMENDING THE CITY’S FEE SCHEDULE
Community Development Manager Sarah Madden provided a brief background on this item. The Council
was being asked to consider Ordinance No. 591, amending Title 3: Business and License regulations to
add a new Chapter 5A: Short Term Rentals; authorizing publication of a summary ordinance to adopt
Ordinance No. 594, amending the City’s Fee Schedule by establishing a Short Term Rental License fee.
Councilor Lorberbaum acknowledged the intent to remove the maximum allowed number of days. She
noted the requirement for the owner to reside onsite for at least half the year and asked if the property
could only be rented while the owner is at the property.
Community Development Manager Sarah Madden replied that the owner would not need to be on the
property while renting it for a short-term basis.
Councilor Lorberbaum asked if the property could then be rented 100 percent of the time.
Community Development Manager Sarah Madden confirmed that could be done as long as all the other
performance standards are met.
Mayor Levine commented that there was a family that came forward who has a unit in their home that
they rent out.
Councilor Lorberbaum asked and received confirmation that all existing rentals would not be
grandfathered in and would need to apply and meet the standards. She asked if the City is prepared to
enforce these rules.
Community Development Manager Sarah Madden replied that the City has prepared an application form,
and the City is prepared to begin accepting rental applications. She stated that enforcement would be
handled on a case-by-case basis, and they would work with the City Attorney if there were additional
Page 12 of 177
September 17, 2024 Mendota Heights City Council Page 11 of 14
efforts needed after the application process. She confirmed that there is an established process for
enforcement, should that be necessary.
Councilor Paper asked if there would be a home inspection after application.
Community Development Manager Sarah Madden confirmed that there would be an initial inspection to
verify compliance with the ordinance. She stated that the cost for that service would be covered by the
$200 annual fee.
Councilor Paper asked if that $200 fee would cover the cost of the inspection and any related staff time.
Community Development Manager Sarah Madden noted the items that would be inspected at the home,
noting that it is not a full home inspection.
Councilor Paper asked if there were other violations noted during that inspection or whether they were
only looking at the number of habitable rooms and smoke/CO2 detectors.
Community Development Manager Sarah Madden replied that the inspection would only focus on the
terms within the ordinance.
Councilor Paper commented that he would want the inspection to verify that there is in fact a fire
extinguisher onsite.
David Epstein, 2234 Swan, stated that he is a real estate broker and renovates properties as well. He stated
that sometimes the highest and best use of a property is as a short term rental. He stated that this is a good
ordinance if the City does not want to allow short term rentals. He stated that he does not live in any
properties that he is renting out. He stated that requiring properties to be homesteaded in order to rent for
short term rentals would eliminate the possibility of people earning revenue on their property. He stated
that he moved to Mendota Heights for the safety that comes with it and because the local government does
not overreach. He believed that this could be written in a way that allows for homes that are not
homesteaded to be rented.
John Maczko, 750 Cheyenne Lane, stated that this is a residential community and short-term rentals are
different. He did not believe people want businesses conducted in their neighborhood with a new family
showing up every seven days. He commented that the rotating cast of people does not allow you to form
a sense of community. He believed that the community is more suited for long term rentals. He did like
the homestead clause and believed that proof would need to be provided during the application process.
Community Development Manager Sarah Madden commented that the license requirements speak of
primary residence requirements and noted that could be clarified in the ordinance itself if desired.
Councilor Mazzitello confirmed that it is a bit confusing and that could be cleaned up within the ordinance.
Mayor Levine confirmed the consensus of the Council for that language to be cleaned up. She thanked
Mr. Epstein for coming, but noted that they have been talking about this for one year and the decision to
require a homesteaded property was not taken lightly by this Council.
Page 13 of 177
September 17, 2024 Mendota Heights City Council Page 12 of 14
Councilor Mazzitello stated that he would like the City Attorney to review Mr. Bellville’s submission.
City Attorney Amy Schmidt stated that she did review some of the citations listed in the letter but has not
done an exhaustive legal review. She stated that a lot of the cases that were cited relate more to the zoning
authority of the city. She stated that in this ordinance the Council would be exercising its licensing
authority.
Councilor Mazzitello asked when the moratorium expires.
Community Development Manager Sarah Madden replied that the moratorium expires on Thursday,
September 19th.
Councilor Paper asked if the Council could review this after one year, similar to many other changes the
City has made.
Mayor Levine commented that she does not see any problem passing the ordinance today, as there is
nothing in this ordinance that is not included in the ordinances of other cities.
City Attorney Amy Schmidt commented that even if adopted tonight, the ordinance would not take effect
until it is published and therefore there will be a period of time where the moratorium expires, and the
ordinance is not in effect.
Councilor Lorberbaum asked if the moratorium could be extended.
City Attorney Amy Schmidt replied that she did not believe that the moratorium falls into the category of
that which could be extended.
Councilor Mazzitello commented that there is no grandfathering in, once the ordinance is adopted, all
short term rentals would need to fall under the ordinance. He stated that at the October 1st meeting he
would like to see the revisions and the opinion of the City Attorney on the letter submitted by Mr. Bellville.
Councilor Mazzitello moved to TABLE CONSIDERATION OF THIS ITEM TO THE OCTOBER 1,
2024 MEETING.

CITY OF MENDOTA HEIGHTS
DAKOTA COUNTY
STATE OF MINNESOTA
DRAFT Minutes of the City Council Work Session
Tuesday, September 17, 2024
Pursuant to due call and notice thereof, a work session of the Mendota Heights City Council was
held at City Hall, 1101 Victoria Curve, Mendota Heights, Minnesota.
CALL TO ORDER
Mayor Levine called the work session to order at 5:01 p.m. Councilmembers Lorberbaum,
Mazzitello, and Paper were also present. Councilmember Miller was absent.
Others present included City Administrator Cheryl Jacobson, Public Works Director Ryan Ruzek,
Finance Director Kristen Schabacker, Park and Recreation/Assistant Public Works Director
Meredith Lawrence, Assistant City Engineer Lucas Ritchie (arrived 6:10 pm), Community
Development Manager Sarah Madden, Police Chief Kelly McCarthy, and City Clerk Nancy Bauer.
LOCAL AFFORDABLE HOUSING AID (LAHA) WITH DAKOTA COUNTY COMMUNITY
DEVELOPMENT AGENCY (CDA)
Tony Schertler, Executive Director and Lisa Alfson, Director of Community and Economic
Development with Dakota County Community Development Agency (CDA) presented
information on the Local Affordable Housing Aid (LAHA) program.
T. Schertler explained that the Minnesota Legislature in May 2023 passed a housing bill for new
funding for various housing programs. State funds were appropriated for programs and a metro-
wide sales tax for housing needs was established, including a portion of this tax as local housing
aid for metropolitan cities. The new law established a 0.25% metropolitan regional sales tax.
Schertler explained that the CDA does not receive a direct LAHA allocation, but Dakota County
will. He added that the city is expected to receive $43,876.81 in 2024. The MN Department of
Revenue will distribute the funds to Mendota Heights in two allocations; one already received on
July 10, and one expected on December 26. The funds come with annual reporting requirements
and reporting will start December 1, 2025. The funds received must be spent within three years
on a qualifying project or returned to Minnesota Housing. The program's income limits for
homeownership are up to 115% AMI (area median income). The income limits for renting are up
to 80% of AMI.
Lisa Alfson shared that the CDA had been meeting with cities to discuss the need for affordable
housing and how the LAHA funds could be used. Alfson discussed the eligible uses of the funds
including construction, acquisition, rehabilitation, demolition, removal of existing structures for
6.b
Page 17 of 177
September 17, 2024, Mendota Heights City Council Work Session Minutes Page - 2
homeowners or rental assistance; financing for home ownership or rental housing; and emergency
rental assistance and financial support to nonprofit affordable housing providers.
It was shared that the city will need to decide how to use the funds. Alfson discussed a potential
partnership between the city and CDA where the CDA could administer three potential programs
on the city’s behalf: 1) an enhanced single-family home improvement loan program, 2) radon
mitigation grant program, or 3) a preservation and new construction gap financing program.
The CDA’s proposed role, and responsibilities would be to: administer the programs; complete
state reporting on behalf of the City’s LAHA funded and CDA programs; and provide quarterly
reports and updates to the city partners.
Alfson explained that to move forward, the CDA is seeking approval from the CDA board to hire
a full-time housing improvement specialist to deploy LAHA funds. A letter will be sent to cities
outlining a formal request to partner on LAHA funds. To meet implementation deadlines, cities
will need to decide by the end of November. A Joint Powers Agreement would be put in place to
carry out the programs.
Mayor Levine said she would be interested in seeing the funds used for upgrading the tot lot at the
CDA’s workforce housing development and to address multi-generational housing. Tony
Schertler said that multi-generational housing improvements would be a good idea for a pilot
project, if a developer could be found for that type of project, and if the family qualified for the
funds.
Councilmember Mazzitello stated that he agrees with multi-generational housing.
City Administrator Jacobson asked if Mendota Heights’ funds would be kept in its own fund or
put in a pool with other cities. Tony Schertler responded that the assumption is that the dollars
allocated to Mendota Heights stays in Mendota Heights. The CDA would do the accounting of
the funds.
Councilmember Lorberbaum said she liked all three ideas that were presented to use the LAHA
funds.
Councilmember Paper said he liked the idea of the CDA administrating the LAHA funds.
Mayor Levine asked if council members were supportive of partnering with the CDA to implement
the LAHA funds.
Councilmembers confirmed their support for collaboration with the Dakota County CDA with
funds directed towards an enhanced single-family home improvement loan program and radon
mitigation grant program.
POLICE DEPARTMENT AND CITY HALL BUILDING OVERVIEW
Page 18 of 177
September 17, 2024, Mendota Heights City Council Work Session Minutes Page - 3
Police Chief McCarthy asked the Mayor and council members to hold a work session in November
to discuss their vision for the police and city hall campus. A clearer vision is needed for the future
building project.
Councilmember Mazzitello confirmed that what was being asked of the Council was to define their
parameters for a project scope.
The value of the current building was discussed. Mayor Levine said she would like to move
forward with plans to submit a request for State bonding dollars again. A budget amount needs to
be figured out.
Community engagement and public involvement were discussed for a new campus. Bonding and
financing for the police/city hall campus were also discussed.
City Administrator Jacobson stated that the November work session is scheduled for November
19.
Councilmember Lorberbaum said the project was overdue and needed to be done.

Hearings
A) PLANNING CASE 2024-18
SOUTHVIEW DESIGN, 643 POND VIEW DRIVE – WETLANDS PERMIT
Community Development Manager Sarah Madden explained that the applicant is seeking a
Wetlands Permit to authorize construction of a new deck structure and landscaping/hardscaping
improvements on the property located at 643 Pond View Drive. A portion of the property is located
within the Wetlands District, which encompasses wetlands and water resource related areas and
the adjacent land within 100 feet of the normal high water markers of these water resources. The
proposed improvements are located at the edge of the Wetlands District boundary, approximately
95.5 feet from the edge of the adjacent Copperfield Pond.
Hearing notices were published and mailed to all properties within 350-ft. of the site; no comments
or objections to this request were received.
Community Development Manager Sarah Madden provided a planning staff report and a
presentation on this planning item to the Commission (which is available for viewing through the
City’s website).
Staff recommended approval of this application based on the findings and with conditions.
Page 20 of 177
6.c
August 27, 2024 Mendota Heights Planning Commission Meeting Page 2 of 7
Acting Chair Corbett referenced the suggested tree protection and asked for more details on what
prompted that addition.
Community Development Manager Sarah Madden commented that she opted to include that based
on current policy discussions, but noted that is not a current requirement of City Code and therefore
would be optional for the Commission to include.
Alison Landmark, Southview Design, commented that their goal is to be surgical in the planning
and construction for this project because of the adjacent wetland and natural area that takes up a
large portion of the backyard. She noted that a portion of the property is totally excluded from the
scope of work and the deck footprint would not go further than the current deck footprint.
Rory Dubin, property owner, commented that they worked with this team on their front yard
project last year and are excited to continue. He stated that they do not have any issues with
protection of the tree as suggested as they are keeping the tree.
Acting Chair Corbett opened the public hearing.
Seeing no one coming forward wishing to speak, Acting Chair Corbett asked for a motion to close
the public hearing.
COMMISSIONER STONE MOVED, SECONDED BY COMMISSIONER KATZ, TO CLOSE

tree protection and that the applicant agreed. He stated that he would support similar language
when applicable going forward.

tree.
Page 22 of 177

AYES: 5
NAYS: 0
Acting Chair Corbett advised the City Council would consider this application at its September 3,
2024 meeting.
New and Unfinished Business
A)ZONING CODE UPDATE
Planning Consultant Jennifer Haskamp presented the Final Draft of the Zoning Code Update. The
City has prepared proposed amendments to Title 12: Zoning to adopt a revised zoning title and
corresponding Zoning Map. This item was tabled from the July 23, 2024, regular Commission
meeting, where the public hearing was opened, held, and closed. The Planning Commission met
at a Worksession on July 30, 2024, to continue to discuss the comments received at the July 23rd
meeting.
Hearing notices were published and mailed to all properties within 350-ft. of the site; no comments
or objections to this request were received. The Commission is asked to reopen the public hearing
and continue its discussion of this item.
Planning Consultant Jennifer Haskamp provided a planning staff report and a presentation on this
planning item to the Commission (which is available for viewing through the City’s website).
Staff recommended adoption of Zoning Code updates as presented.
Commissioner Katz thanked staff for continuing to go through the drafts and answer questions,
acknowledging that this has been a long process.
Acting Chair Corbett reopened the public hearing.
Tim Lawrence, Alltech Engineering, referenced the proposed rezoning which would rezone a lot
of industrial property to general business. He commented that it would seem that a number of
current uses would not be included in the allowed table of uses for general business, using the
example of metal fabrication.
Commissioner Petschel commented that he specifically mentioned that use as something they
wanted to allow and therefore if it is not listed, it should be. He believed that would fall under the
definition of manufacturing.
Mr. Lawrence asked the purpose of rezoning the parcels.
Page 23 of 177
August 27, 2024 Mendota Heights Planning Commission Meeting Page 5 of 7
Commissioner Petschel commented that those properties are not currently be rezoned. He stated
that there is only one parcel in the industrial district being reguided as general business, and
identified that parcel.
Planning Consultant Jennifer Haskamp identified the stretch of property proposed to be rezoned.
She explained that this is a follow up from the Comprehensive Plan guiding which had an intent
to better match the existing uses of the property.
Mr. Lawrence stated that he is seeking to understand the purpose of the change as his business is
similar to many in that area. He stated that while their business is not engaging in manufacturing,
they support industrial businesses and does not want the other businesses to be impacted by the
change in zoning.
Commissioner Stone asked how they could ensure that this would not impact the current
businesses that are there.
Community Development Manager Sarah Madden stated that the map itself has looked like this
for some time because of the Comprehensive Plan guiding and cannot be separated from the
Zoning Code update at this point. She stated that the table of uses could be updated.
Planning Consultant Jennifer Haskamp stated that the existing businesses are protected as they
would predate the changes to the Code and would be legal nonconforming uses. She stated that
there was discussion that the existing businesses better match B-1 and if that is not the case, that
whole section could be recommended to revert back to industrial. She stated that uses could also
be added to the allowed uses if desired.
Commissioner Stone asked the number of uses of that nature in that area.
Public Works Director Ryan Ruzek commented that there may be one, noting that block may be
better served as industrial and east of Pilot Knob Road he is not familiar with industrial-type
properties. He stated that the map could therefore be modified, or if the intent is to have more
general business in the future, the map could be left as proposed.
Acting Chair Corbett commented that they would not want to adversely impact businesses or
properties.
Commissioner Petschel stated that perhaps manufacturing is added as a conditional use within
general business.
Planning Consultant Jennifer Haskamp reviewed the changes that could be made to allow those
uses conditionally within general business.
Commissioner Johnson suggested they look at the other B-1 zoning areas because that change
would then open it up in those areas.
Page 24 of 177
August 27, 2024 Mendota Heights Planning Commission Meeting Page 6 of 7
Commissioner Petschel commented that manufacturing is already allowed, noting that there is just
a specification on certain methods that are not allowed.
Planning Consultant Jennifer Haskamp reviewed some of the allowed industrial activities that
would not be allowed within general business. She stated that if those uses seem appropriate for
this strip of property, then she would suggest changing that area back to industrial rather than
adjusting the table.
Community Development Manager Sarah Madden commented that as suggested by Public Works
Director Ryan Ruzek, they could adjust the portion of the block west of Pilot Knob back to
industrial.
Commissioner Stone asked the opinion of the planning consultant.
Planning Consultant Jennifer Haskamp commented that if those uses, she reviewed feel consistent
with what is going on, and what they would like in the future, she would recommend the map
change. She noted that it has been two years since the last review and discussion related to the
map change.
Commissioner Petschel stated that he would be comfortable going that route, as in reviewing the
current uses, that seems to be more appropriate as industrial.
Planning Consultant Jennifer Haskamp commented that would still be consistent with the
Comprehensive Plan.
The Commission thanked Mr. Lawrence for his input.
Seeing no one further coming forward wishing to speak, Acting Chair Corbett asked for a motion
to close the public hearing.

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Approve Amendment to the Professional Services Contract for the Friendly
Hills Neighborhood Improvements
ITEM TYPE: Consent Item
DEPARTMENT: Engineering CONTACT: Lucas Ritchie, Asssitant City
Engineer
Ryan Ruzek, Public Works
Director
ACTION REQUEST:
Approve an amendment to the professional services contract on the Friendly Hills
Neighborhood Improvements, Project No. 202407.
BACKGROUND:
The Friendly Hills Neighborhood Improvements have been identified in the 2025-2029 Capital
Improvement Plan (CIP) for construction in 2025 and 2026. These streets currently have
deteriorating bituminous surfaces along with aging public utilities and will benefit from a
rehabilitation project to preserve the public infrastructure.
The Council previously authorized a professional services contract with Kimley-Horn at their
March 6, 2024 meeting and an amendment at their June 4, 2024 meeting to rehabilitate the
following streets within the Friendly Hills Neighborhood totaling 3.56 miles of roadway:
Apache Court, Apache Lane, Apache Street, Aztec Lane, Cheyenne Lane, Creek Avenue,
Decorah Lane, Fox Place, Havenview Court, Hazel Court, Hokah Avenue, Keokuk Lane, Mohican
Court, Mohican Lane, Nashua Lane, Navajo Lane, Ocala Court, Ocala Lane, Pagel Road, Pontiac
Place, Pueblo Drive, and Pueblo Lane.
Previous Council discussion has prompted further investigation towards the pavement
rehabilitation method for areas with limited utility improvements within the project. Staff and
the City’s consultant have engaged the geotechnical testing firm to collect additional
pavement data and provide a recommendation for the method of pavement rehabilitation that
was not originally included within the approved scope of services.
Page 32 of 177
FISCAL AND RESOURCE IMPACT:
The original contract amount with Kimley-Horn for providing professional services on the
project is $599,885. As the project was split into two years and additional streets were added,
the first amendment to the original contract revised the contract amount to $664,185. The

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Approve Trail Easement for 1441 Clement Street
ITEM TYPE: Consent Item
DEPARTMENT: Engineering CONTACT: Ryan Ruzek, Public Works
Director
ACTION REQUEST:
Approve an easement for trail purposes over the 1441 Clement Street property.
BACKGROUND:
The city of Mendota Heights approved the Ivy Falls South plat in 1995. The plat extended
Knollwood Lane south from Emerson Avenue. As part of the development, a trail was
constructed connecting Knollwood Lane to Clement Street. The Developers Agreement
required the developer to record an easement for the trail. Adjacent to the trail are several ash
trees that have died due to infestations from the Emerald Ash Borer on the 1445 Knollwood
Lane property. The homeowners asked that the city remove the trees as they are a hazard to
pedestrians.
Staff searched for the easement to review the requirements of the city to manage the trees.
Upon this review, it was determined that the trail easement does not exist. Staff worked with
the homeowners on developing the attached easement for trail purposes. The city resolved
the easement at 1445 Knollwood Lane and has removed the hazard ash trees.
FISCAL AND RESOURCE IMPACT:
The City will need to make payment of one dollar as a financial transaction for the easement.

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Memorandum of Understanding with NDC4 Modifying the Allocation of
Cable Franchise Fee Revenues
ITEM TYPE: New and Unfinished Business
DEPARTMENT: Administration CONTACT: Cheryl Jacobson, City
Administrator
ACTION REQUEST:
Approve a Memorandum of Understanding with the Northern Dakota County Cable
Communications Commission (NDC4) to modify the established allocation of cable franchise
fee revenue.
BACKGROUND:
The city of Mendota Heights is one of seven member cities that formed the Northern Dakota
County Cable Communications Commission in 1982 via a joint powers agreement. Other
member cities include South St. Paul, West St. Paul, Inver Grove Heights, Sunfish Lake, Lilydale
and Mendota. On behalf of its member cities, NDC4 administers and enforces the cable
franchise, manages institutional programming - like the broadcast and streaming of city
council and commission meetings, and oversees local community programming.
The city currently has a cable franchise agreement whereby, in exchange for the use of public
right-of-way, the cable franchisee (Comcast) pays a franchise fee and PEG (Public, Educational,
and Governmental) fee to NDC4. In turn, NDC4 retains 75% of the fee revenue and the
remaining 25% is disbursed to the member cities. The city receives its share of franchise fees
in the spring for the year prior (i.e. fiscal year 2023 fees are paid in the spring of 2024). This
year the city received $49,584.
Cities across the country are experiencing decreasing franchise fees and PEG fee revenues
from cable operators due to “cord cutting” and changes in the television/video marketplace.
Cord-cutting refers to subscribers canceling cable TV service and switching to a cheaper
alternative, like streaming. At this same time, NDC4 is experiencing increasing operating costs.
NDC4 (and Town Square Television) have been working on budget plans to reduce costs and
Page 65 of 177
diversify revenue streams and have also helped lead a legislative effort seeking a legislative
solution to modernizing the funding structure for local rights-of-way and PEG programming.
To aid in these efforts, NDC4 is requesting that:
1.Member cities waive their portion of one-time audit settlement payments which are a
result of a recent audit of Comcast's franchise fee payments; and
2.Agree to a reduction in franchise fees for FY2024 (paid in 2025) to 12.5%, and a
reduction in the city's share of 2025 franchise fees (paid in 2026) to 6.25%.
NDC4 has prepared the attached Memorandum of Understanding and will present information
at the October 1 city council meeting.
FISCAL AND RESOURCE IMPACT:
The anticipated payment amount in 2025 would be $23,404, which is approximately $26,000
less than that received in 2024 (for fiscal year 2023).

MEMORANDUM OF UNDERSTANDING
This Memorandum of Understanding (“MOU”) is by and between Northern Dakota County Cable
Communications Commission (“Commission”) and the cities of Inver Grove Heights, Lilydale,
Mendota, Mendota Heights, South St. Paul, Sunfish Lake, and West St. Paul, Minnesota (“Member
Municipalities”) (each individually a “Party” and collectively referred to as the “Parties”).
RECITALS:
1.The Commission is governed by the Amended Joint and Cooperative Agreement adopted
by the Member Municipalities (“JPA”); and
2.In the fall of 2020, the Member Municipalities each adopted an ordinance granting a cable
franchise to Comcast of St. Paul, Inc. (“Comcast”) for a ten (10) year term that obligates Comcast
to submit a franchise fee of five percent (5%) of its quarterly gross cable service revenues.
3.Article X, Section 5 of the JPA provides that the Commission shall collect all franchise
fees paid by Comcast and shall annually pay (payment remitted in April of the following year) the
Member Municipalities twenty-five percent (25%) of the franchise fees received by the
Commission (“Annual Contribution”); and
4.The number of Comcast cable subscribers in the Member Municipalities has decreased
over the past decade and has resulted in lower franchise fee payments received by the Commission;
and
5.The Commission contracted with Ashpaugh and Sculco (“A&S”) to conduct a review of
the franchise fees submitted by Comcast for the years January 1, 2015 through December 31, 2019
(“Review Period”); and
6.A&S submitted its findings to the Commission in a report dated, July 23,2021 (“Report”);
and
7. The Commission and Comcast settled the findings contained in the Report resulting in the
Commission receiving payments from Comcast for past due franchise fees and late penalties
totaling Two Hundred Eighty Thousand Ninety-four Dollars and 72/100 ($280,094.72)
(“Settlement Amount”); and
8.The Member Municipalities recognize that the Commission expended significant resources
to achieve the Settlement Amount, the Settlement Amount was not budgeted for by the Parties and
this one-time settlement would be beneficial to the Commission to address current financial needs
resulting from the reduced franchise fee payments received from Comcast; and
9.The Parties further desire to reduce the Annual Contribution to further assist the
Commission; and
10.This MOU has been negotiated in good faith by the Parties.
NOW THEREFORE, the Commission and the Member Municipalities agree as follows:
1. This MOU shall become effective on October 1, 2024.
Page 67 of 177
2
9617326v2
2.The Settlement Amount shall not be subject to any Annual Contribution set forth in Article
X. Section 5 of the JPA.
3.The Annual Contribution set forth in Article X. Section 5 of the JPA shall be reduced as
follows:
a.12.5% for 2024 (received by the Member Municipalities in April 2025),
b. 6.25% for 2025 (received by the Member Municipalities in April 2026),
4.The Annual Contribution amount for any years other than 2024 (received in 2025) and
2025 (received in 2026) shall not be reduced or otherwise modified except as may be approved in
writing by the parties at a future date.
5.This MOU will be governed by and interpreted and construed in accordance with the laws
of the State of Minnesota.
6.This MOU may be amended at any time by written agreement between the Parties.
7.This MOU may be executed in counterparts, each of which is deemed an original, but all
of which together are deemed to be one and the same agreement. A signed copy of this MOU
delivered by e-mail or other means of electronic transmission is deemed to have the same legal
effect as delivery of an original signed copy of this MOU.
IN WITNESS WHEREOF, this MOU has been executed by the duly authorized representatives
of the Parties as set forth below.

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Mendota Heights Police Department 2020 Project
ITEM TYPE: New and Unfinished Business
DEPARTMENT: Police CONTACT: Kelly McCarthy, Police Chief
ACTION REQUEST:
Approve reimbursement for the purchase of a home gun safe for each Mendota Heights Police
Officer.
BACKGROUND:
In 2020, firearms became the leading cause of death among children in the United States.
These deaths are entirely preventable. Thirty million children live in homes with firearms and
80% of children who die by firearm suicide use a gun that belonged to a family member. We
issue firearms to all of our officers. Mendota Heights Police policy 305.5.2 states, "Members
shall ensure that all firearms and ammunition are locked and secured while in their homes,
vehicles or any other area under their control, and in a manner that will keep them inaccessible
to children and others who should not have access."
As part of our ongoing commitment to community safety and officer wellness, we want to
make it as easy as possible for officers to follow policy and to ensure the safety of their family.
To that end, I am asking that the City authorize reimbursements for the purchase of a home
gun safe for each officer (not to exceed $200 per officer).
To raise awareness of the issue and the program, officers will be issued custom patches that
can be worn on uniforms in June and October (if they so choose). The patches can also be sold
to the public to cover the costs of the reimbursements.
FISCAL AND RESOURCE IMPACT:
The maximum cost to the city to start the program is $4,595. The purchase price of the
patches is $595.00 and $4,000 for safe reimbursements. The program could add $200 to the
outfitting of new hires in the future. The $4,595 will come from the department's clothing and
equipment budget.

•In 2020, firearms became the leading cause of death among
children in the United States (Center for Disease Control).
•Youth firearm suicide has reached its highest rate in more than
20 years.
•30 Million American children now live in homes with firearms
•80% of firearm suicides by people 18 or younger involve a gun
that belonged to a family member.
Page 73 of 177
•The Journal Injury Prevention published that many law
enforcement officers who own firearms fail to store them safely.
•The study found 71% of Officers had a gun at home and only
40% were stored in a safe.
•“Historically, law enforcement officers have had higher rates of
suicidal thoughts and behaviors,” said study first author Allison
Bond, of the New Jersey Gun Violence Research Center at
Rutgers.
Page 74 of 177
2020 Project – An overview
•As part of our on-going commitment to officer safety and
wellness, the City of Mendota Heights will reimburse each officer
up to $200 for the purchase of a home gun safe.
•The MHPD will create a safe storage fact sheet to distribute at
events and with the issuance of a permit to purchase.
Page 75 of 177
2020 Project
•To further raise awareness, a
special edition police patch will
be issued to officers and can be
worn on their uniform during the
month of June and sold to the
public to cover the cost of the
program.DRAFT
Page 76 of 177
We know that hindsight is 2020.
No parent would ever purchase or allow access to a gun if they
knew it would be used in a suicide.
Help the Mendota Heights Police Department raise awareness
and create safer homes for our officers and their families by voting
to approve the MHPD 2020 Project.

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Planning Case 2024-17 - Consider Resolution 2024-56 Approving a MRCCA
Permit and Amended CUP for Xcel Energy at 800 Sibley Memorial Highway
ITEM TYPE: New and Unfinished Business
DEPARTMENT: Community Development CONTACT: Sarah Madden, Community
Development Manager
ACTION REQUEST:
Adopt Resolution 2024-56, Approving a Mississippi River Corridor Critical Area Permit and
amended Conditional Use Permit for Xcel Energy at the Sibley Propane Tank Facility located at
800 Sibley Memorial Highway
BACKGROUND:
The subject property is generally known as the Sibley Propane Gas Plant facility and is located
south and east of State Trunk Highway 13/Sibley Memorial Highway, and abuts Valley Park to
the south, commercial/office developments to the north, and residential neighborhoods to the
east. The plant property contains two parcels comprised of approximately 25 total acres, which
are all owned and operated by Xcel Energy (formerly Northern States Power Company).
According to Xcel representatives, the plant use has existed in its current location since the
mid-1950s. Xcel Energy is seeking approval of a Mississippi River Corridor Critical Area
(MRCCA) Permit and an amended Conditional Use Permit, in order to implement a number of
improvements to the Sibley Propane Plant facility.
The site has previous MRCCA approvals (and prior Critical Area Permit (CAP) approvals) for site
functional and safety improvements. A recent 2022 approval authorized a replacement of the
propane loading facilities, significant upgrades to stormwater management, and installation of
a new watermain for fire suppression infrastructure. In 2016, the City approved a Conditional
Use Permit (CUP) and CAP related to improvements to a structure on the Sibley Plant property.
‘Essential Services’ is a listed Conditional Use in the B-1A zoning district, and prior to that
application, the site did not have a record of Conditional Use Permit approval for the use, due
to the age and historical use of the property. That approval included a condition that future
site alterations would be subject to an amendment to the CUP approval.
Page 78 of 177
Xcel is now completing other elements and improvements needed for this tank facility, and are
requesting official consideration of this work under a new MRCCA Permit, and which work
includes the following:
1. Mound soil around the existing propane tanks, as part of the fire suppression system
for the facility;
2. Install a six-ft tall retaining wall at the south side of the existing pump manifold station;
3. Install a storm shelter on a 12-ft x 24-ft concrete pad foundation within the fenced
compound; and
4. Expand the compound on the east side to allow for fire truck access along the east
perimeter of the fenced compound, by adding additional fencing.
According to the Xcel’s narrative, the proposed work will bring the site into compliance with
National Fire Prevention Association (NFPA) codes and design standards. The maintenance
and refurbishment of the facility is ongoing, with work taking place in 2024 that was reviewed
as part of the prior MRCCA Permit, such as the installation of the water-main and ongoing
permitting for the pipe bridge and pump house.
Pursuant to City Code Section 12-3-12, no building permit, zoning approval, or subdivision
approval shall be issued for any action or development located in an area covered by this
chapter until a site plan has been prepared and approved in accordance with the provisions of
this chapter. The ordinance also provides for rules and standards for new developments,
which may include land alteration activities and vegetation management (removals and
replanting).
The entirety of the work will take place within the fenced compound of the Sibley Plant which
has been maintained as an asphalt and gravel surface and contains no vegetated areas. No
work is proposed in any Primary Conservation Areas (PCA’s) on the property and all existing
vegetation outside the site compound will remain. The only expansion of the site compound is
the additional fencing which is proposed on the southeast side of the tank farm to widen the
area and provide fire truck access. Site work will consist of bringing in the soil to bury the
above-ground storage tanks within the mounding system. There are no major building
improvements proposed under this project, except for a small- storm shelter, which will be a
prefabricated building placed on a 12-ft x 24-ft foundation. The building will be a shell for the
purposes of providing employees and contractors working on the site with an Emergency
Preparedness shelter for severe weather events. This is proposed to be located north of the
tank farm and existing structures on the site, and west of the pipe bridge.
The primary focus of the project is dedicated to mounding soil around the propane tanks as
part of the fire suppression system for the Sibley Plant. This mounding of soil will be used
instead of an overhead sprinkler system, which was discussed as part of the former 2022
permit approval. The 6-ft tall retaining wall is proposed to limit the amount of grading on the
site and maintain the footprint of the existing plant, keeping the area of disturbance
contained. The grading and mounding of the tank farm modifies the former stormwater
management plan. A detention pond is still located southeast of the tank farm, however, the
Page 79 of 177
exact location has shifted closer to the boundary of the tanks, and the drainage path now
circulates south around the tanks to connect to the culvert system and riprap located west of
the tank farm. The basin is meant to pre-treat stormwater runoff, but also help reduce runoff
from reaching the bluff and BIZ on the west; which will help with slope stability that has been
needed in the westerly slope area. There are no changes to the riprap drainage channel within
the Bluff Impact Zone that was illustrated and included in the 2022 approval.
At the September 24, 2024 Planning Commission meeting, a planning report was presented. A
duly noticed public hearing was held, and two members of the public spoke at the meeting to
provide comments about the site improvements. The applicant was present to speak to the
application and answer questions from the Commissioners and clarify technical details about
the project proposal.
The Planning Commission discussed the site plan and the modification of fencing. A comment
was shared at the public hearing that questioned the full extent of the fencing change and
wanted to clarify that the existing access to Farmdale Road would not be modified. Members
of the applicant team addressed the Commission and attendees to confirm that the only area
of fencing to be modified was the corner immediately southeast of the southernmost row of
tanks and that the secondary safety access path to Farmdale Road was not planned to be
modified or improved, and would continue to function only as a secondary emergency access
path to the tanks, and is not part of the unloading pathway at all.
A copy of the 9/24/24 planning report with attachments and an excerpt from the unapproved
minutes are attached to this report. As noted in the attachments, staff recommended approval
of the MRCCA Permit and amended CUP. Following their discussion, the Planning Commission
determined that the applicant met the conditions set forth in City Code Section 12-3-1 and
voted unanimously (6-0) in support of Xcel Energy’s request with findings-of-fact and certain
conditions, as outlined in the attached [draft] Resolution.

PLANNING STAFF REPORT
DATE:September 24, 2024
TO:Planning Commission
FROM:Sarah Madden, Community Development Manager
SUBJECT:Planning Case No. 2024-17 - MRCCA PERMIT/AMENDED CUP
APPLICANT:Xcel Energy
PROPERTY ADDRESS:800 Sibley Memorial Highway
ZONING/GUIDED:B-1A Business Park / LB- Limited Business
ACTION DEADLINE:November 11, 2024
INTRODUCTION
Xcel Energy (Northern States Power Company) is seeking approval of a Miss. River Corridor Critical
Area (MRCCA) Permit and Conditional Use Permit, in order to implement a number of
improvements to the Sibley Propane Plant facility, located at 800 Sibley Memorial Highway.
This item is being presented under a duly noticed public hearing process. A notice of hearing was published in the Pioneer Press; and notice letters were mailed to all owners within 350-feet of the subject property, including the cities of St. Paul and Lilydale. The city has not received any objection or comments related to this application as of the submission of this report.
BACKGROUNDThe subject property is generally known or identified as the Sibley Propane Gas Plant facility, which is located south and east of State Trunk Highway 13, and abuts Valley Park to the south, commercial/office developments to the north, and Park Place and Summit residential neighborhoods to the east (refer
to GIS image – right). The plant property contains two parcels comprising of approximately 25 total acres,
which are all owned and operated by Xcel Energy
(formerly Northern States Power Company).
According to Xcel representatives, the plant use has
existed in its current location since the mid-1950’s.
The site is fairly open with security style fencing
around its perimeter, and contains a number of
support structures and buildings that house
Page 87 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 2
office/work spaces, maintenance areas, valve/mixing rooms, and includes 37 horizontal laying propane tanks on the back side of the plant site (referred to as the “Tank Farm”)
The plant is used primarily to feed propane into the local natural gas line systems during periodic “spikes” or peak demand events, typically experienced in winter heating season months and only as needed.
In 2016, the City approved a Conditional Use Permit and Critical Area Permit related to improvements to a structure on the Sibley Plant property. ‘Essential Services’ is a listed Conditional Use in the B-1A zoning district, and prior to that application the site did not have a record of Conditional Use Permit approval for the use, due to the age and historical use of the property.
In August 2021, Xcel received an Administrative Critical Area Permit, in order to complete some immediate and mandatory infrastructure improvements to this plant. These upgrades included
replacing some outdated and worn out valves, pipes and equipment with new modern materials,
equipment, pipes, valves and miscellaneous safety measures. Due to the importance of providing
continued natural gas service to the community and region, and ensuring that gas is available to
local customers when the cold/winter season comes, these equipment upgrades and the work
proposed by Xcel were deemed essential to the general public, and the council elected to expedite
this work under an Administrative Critical Area Permit approval.
In May 2022, the City reviewed a full MRCCA Permit application for additional improvements to
the tank facility, including replacing the propane loading facilities, improvements to the
stormwater management on site, and a new fire suppression system. The fire suppression system
included a new 12-inch watermain extension coming from the water main line underneath
Farmdale Road to the east. At that time, drainage issues on site were also proposed to be addressed through a re-grading of the site, a new detention basin, and a network of concrete stormwater trenches within the tank field.
Xcel is now completing other elements and improvements needed for this tank facility, and are requesting official consideration of this work under a new MRCCA Permit, and which work includes the following:
1. Mound soil around the existing propane tanks, as part of the fire suppression system forthe facility;
2. Install a six-ft tall retaining wall at the south side of the existing pump manifold station;
3. Install a storm shelter on a 12-ft x 24-ft concrete pad foundation within the fencedcompound; and
4. Expand the compound on the east side to allow for fire truck access along the eastperimeter of the fenced compound, by adding additional fencing.
According to the Xcel’s narrative, the proposed work will bring the site into compliance with
National Fire Prevention Association (NFPA) codes and design standards.- The maintenance and
refurbishment of the facility is ongoing, with work taking place in 2024 that was reviewed as part
of the prior MRCCA Permit, such as the installation of the water-main and ongoing permitting for
the pipe bridge and pump house.
Page 88 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 3
The review and approval also includes an update to their existing Conditional Use Permit (CUP), approved in 2016, which noted that future site alterations would need to be processed as an amendment to the CUP as well as any critical area permits needed.
ANALYSIS – MRCCA PERMITA majority of the plant site is situated in the MRCCA Overlay boundary, and is located within the
SR-Separated by River District.
Along the westerly boundary of the site is where the mapped bluffs are located, identified as the
cross-hatched areas – and the related 20-foot buffer or bluff impact zone (BIZ), as noted by
orange-hatched areas (see MRCCA map image- above).
Properties located in the SR District are characterized or governed by the following principles:
Description. The SR district is characterized by its physical and visual distance from the Mississippi River. The district includes land separated from the river by distance, topography, development, or a transportation corridor. The land in this district is not readily visible from the Mississippi River.Management Purpose. The SR district provides flexibility in managing development without negatively affecting the key resources and features of the river corridor. Minimizing negative impacts to primary conservation areas and minimizing erosion and the flow of untreated storm water into the river are priorities in the district. In addition, providing public access to and public views of the river, and restoring natural vegetation in riparian areas and tree canopy are also priorities in the district.
Per Section 12-3-8. E., Public utilities must comply with the following standards:
1. High-voltage transmission lines, wind energy conversion systems greater than five (5)
megawatts, and pipelines are regulated according to Minnesota Statutes, chapter 216E,
216F, and 216G respectively; and
2. If overhead placement is necessary, utility facility crossings must minimize the visibility of
the facility from the river and follow other existing right of ways as much as practicable.
Page 89 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 4
3. The appearance of structures must be as compatible as practicable with the surrounding area in a natural state with regard to height and width, materials used, and color.
4. Wireless communication facilities must comply with Section 12-3-5.B.6.
There are no new high-voltage line, wind energy systems, pipelines or wireless communication
systems proposed under this project.
Pursuant to new City Code Section 12-3-12, no building permit, zoning approval, or subdivision
approval shall be issued for any action or development located in an area covered by this chapter
until a site plan has been prepared and approved in accordance with the provisions of this chapter.
The new ordinance also provides for new rules and standards for new developments, which may
include Land Alteration activities and Vegetation Management (removals and replanting).
The entirety of the work will take place within the fenced compound of the Sibley Plant which has been maintained as an asphalt and gravel surface, and contains no vegetated areas. No work is proposed in any Primary Conservation Areas (PCA’s) on the property and all existing vegetation outside the site compound will remain. The only expansion of the site compound is the additional fencing which is proposed on the east side of the compound to widen the area and provide fire truck access. Site work will consist of bringing in the soil to bury the above-ground storage tanks within the mounding system. There are no major building improvements proposed under this project, except for a small- storm shelter, which will be a prefabricated building placed on a 12-ft x 24-ft foundation. The building will be a shell for the purposes of providing employees and contractors working on the site with an Emergency Preparedness shelter for severe weather events. This is proposed to be located north of the tank farm and existing structures on the site, and west of the pipe bridge.
The primary focus of the project is dedicated to mounding soil around the propane tanks as part of the fire suppression system for the Sibley Plant (see grading plan image below). This mounding
of soil will be used instead of an overhead sprinkler system. The 6-ft tall retaining wall is proposed
to limit the amount of grading on the site and maintain the footprint of the existing plant, keeping
area of disturbance contained.
Page 90 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 5
The proposed 6-ft retaining wall is just located just north of the tank farm and centered roughly between the two tank zones, as highlighted in the image below (bottom left). The change in fencing is located south east of the southernmost tank area, and adds 83-ft of new fencing at a diagonal angle, allowing an approximately 25-ft in width to facilitate fire truck access. The new line of fencing is illustrated in the image below (bottom right)
Land Alteration Standards and Stormwater ManagementMRCCA Ordinance Section 12-3-10 provides for specific allowances and standards related to Land Alteration and Stormwater Management. The purpose of this section is to establish standards that protect water quality from pollutant loadings of sediment, nutrients, bacteria, and other contaminants, and maintain the stability of bluffs, shorelines, and other areas prone to erosion.
Land Alteration:
Within the bluff impact zone (BIZ), land alteration is prohibited, except for the following, which are
allowed only by permit.
a) Erosion control consistent with a plan approved by the City and consistent with Section 12-3-10.F.
b) The minimum necessary for development that is allowed as an exception under Section 12-3-15; and
c) Repair and maintenance of existing buildings and facilities.
Grading around the tank farm will be significant, due to the mounding proposed as fire suppression within the tank farm. The 2022 MRCCA approval evaluated changes in containment of stormwater runoff, and the applicant prepared a Storm Water Pollution Prevention (SWPP) plan, which is included as an attachment to this report. Due to the level of land disturbance, a SWPP review is necessary, and the applicants will likely need a National Pollutant Discharge Elimination System (NPDES) permit from the Minnesota Pollution Control Agency as well.
Stormwater Management:
In the bluff impact zone, stormwater management facilities are prohibited, except by permit if:
a. There are no alternatives for storm water treatment outside the bluff impact zone on the subject site;
b. The site generating runoff is designed so that the amount of runoff reaching the bluff impact zone is reduced to the greatest extent practicable;
Page 91 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 6
c. The construction and operation of the facility does not affect slope stability on the subject
property or adjacent properties; and
d. Mitigation based on the best available engineering and geological practices is required and
applied to eliminate or minimize the risk of slope failure.
In all other areas, storm water runoff must be directed away from the bluff impact zones or unstable areas.
As part of the previous 2022 MRCCA Permit approval, Xcel intended to construct a new
stormwater detention basin to provide treatment of runoff coming off the tank farm area. The
basin was to be placed in the southeast corner of the tank farm and not be within any BIZ or bluff
setback. The grading and mounding of the tank farm modifies this plan. A detention pond is still
located southeast of the tank farm, however the exact location has shifted closer to the boundary
of the tanks, and the drainage path now circulates south around the tanks to connect to the culvert
system and riprap located west of the tank farm. The basin is meant to pre-treat stormwater runoff,
but also help reduce runoff from reaching the bluff and BIZ on the west; which will help with slope
stability that has been needed in the westerly slope area. There are no changes to the riprap
drainage channel within the Bluff Impact Zone that was illustrated and included in the 2022
approval.
Conditions of Land Alteration Permit ApprovalNo permit for land alteration shall be approved unless:
1. Temporary and permanent erosion and sediment control measures to retain sediment onsite
are consistent with the best management practices in the Minnesota Stormwater Manual, as
it may be amended or revised from time to time;
2. Natural site topography, and soil and vegetation conditions are used to control runoff and
reduce erosion and sedimentation;
3. Construction activity is phased when possible;
4. All erosion and sediment controls are installed before starting any land disturbance activity;
5. Erosion and sediment controls are maintained to ensure effective operation;
6. The proposed work is consistent with the vegetation standards in Section 12-3-9; and
7. Best management practices are used for protecting and enhancing ecological and water
resources as identified in Best Practices for Meeting DNR General Public Waters Work Permit
GP 2004-0001, as it may be amended or revised from time to time.
ANALYSIS – CUPThe 2016 Conditional Use Permit approval established the ‘Essential Services’ use as the zoning use existing on the property, encompassing the service and delivery of the propane at the facility. This current proposal does not modify the primary structures or essential services of the site, but does encompass the addition of a small structure for a storm shelter for employees, and does modify the grading and fire suppression associated with the essential service utility. The existing approval included a condition that ‘future improvements on the subject property that expand, alter, or otherwise change the existing use or site conditions in any manner shall require an amendment to the conditional use permit, including a critical area permit if applicable.’ The proposed improvements do constitute a change in the site conditions through the grading improvements and mounding of the tank farm. No additional performance standards are noted
Page 92 of 177
Planning Case #2024-17 (Xcel – MRCCA Permit) Page 7
with the essential services use in City Code, apart from the applicable provisions for all Conditional Use Permits within the City.
The City may grant a conditional use provided the proposed use demonstrates the following:
a) Use will not be detrimental to the health, safety or general welfare of the community,b) Use will not cause serious traffic congestion nor hazards,c) Use will not seriously depreciate surrounding property value, andd) Use is in harmony with the general purpose and intent of this chapter and the comprehensiveplan.
The site is enclosed by a 10-foot-high, barbed-wire-topped, chain link security fence. As part of Planning Case 1980-08, Northern States Power (NSP) was granted a conditional use permit to relocate and extend portions of the fence. The existing use was also established on the subject
property prior to development of both abutting residential subdivisions to the site. Staff finds the
existing ‘essential services’ use to demonstrate the above requirements for Conditional Use
Permits. In addition, the existing use is compliant with the conditions required for approval of a
conditional use permit within the MRCCA.
As part of the review of a Conditional Use Permit within the MRCCA, the City must note in the
Findings of Fact that the use is consistent with the purpose of the MRCCA ordinance as outlined
below:
a. The extent, location, and intensity of the conditional or interim use will be in substantial
compliance with the MRCCA plan;
b. The conditional or interim use is consistent with the character and management purpose of
the MRCCA district in which it is located;c. The conditional or interim use will not be detrimental to PCAs and PRCVs nor will it contributeto negative incremental impacts to PCAs and PRCVs when considered in the context of past,present, and reasonable future actions; andd. The conditional or interim use will not negatively affect other resources identified in the City'sMRCCA plan, such as wetlands, river overlooks, and parks and open space.
The proposal does not impact any PCA’s on the property, and the proposed improvements are consistent with the purpose of the MRCCA district in which it is located, and the provisions related to public facilities and utilities as outlined in 12-3-8-E. The site is not visible from the river, and the river is not visible from the site, and the tank area maintains its security and separation from neighboring uses through the utilization of fencing and buffered by natural vegetation.
INTERAGENCY REVIEWThe city is required to give Minnesota Dept. of Natural Resources and National Park Service at
least 20-day notice of any new MRCCA Permit application request. These notices were emailed
directly to the appropriate staff; and a response from DNR was received indicating no comment
or issues with the proposed improvement work and project by Xcel; and received no response or
comment from NPS.

Mendota Heights, MN 55118 Email: RE: Sibley Plant Safety Improvements
Conditional Use Permit Amendment & MRCCA Permit
Dear Sarah Madden,
Please find this letter of intent and application materials for the MRCCA Permits and the Conditional
Use Permit Amendment for the NSP (Xcel Energy) Sibley Gas Plant located at 800 Sibley Memorial
Hwy with Parcel ID numbers of 270140075011, 270230002013, 270230002012, 271715102091, and
275660002081. The plant stores propane which can be inserted into the natural gas system during
periods of peak demand in the winter. The plant has been in service since the 1950’s prior to the
incorporation of the City of Mendota Heights. NSP is investing to enhance safety upgrades and
improve plant operations. The primary improvements that we seek are:
•Amend the existing CUP to mound soil around the existing propane tanks. The mounded soilwi
ll be part of the fire suppression system for the facility. The remaining components of the
site plan will not change. Steps, walkways and retaining walls will be installed to allow for
access to the tanks.•Install a six feet tall retaining wall at the south side of the existing pump manifold stationwi
thin the facility in order to hold the mounded soil from the manifold station.
•Install a storm shelter on a 12’ x 24’ concrete pad foundation within the fenced compound.
•Expand the compound on the east side to allow for fire truck access along the east perimeterof
the fenced compound by adding approximately 25 linear feet of fencing.
The proposed work will bring the site into compliance with the National Fire Prevention Association
(NFPA) codes and design standards. The entirety of the work will take place within the fenced
compound of the Sibley Plant which has been maintained as an asphalt and gravel surface. Work will
consist of hauling in soil to bury the above-ground storage tanks. This in combination with other
devises and practices is part of the fire suppression system for the facility.
The property is in the southeast quadrant of and adjacent to I-35E and US Hwy 13. The site is
irregularly shaped and additionally abuts Lilydale Road and Farmdale Road. The property is in the
Critical Area Overlay Zone and includes steep slopes to the south and west and forested land
surrounding the facility. NSP purchased additional buffer land to the east to help screen the facility
from adjacent development to the east. City parkland to the south and east provide additional
screening and buffering. The site cannot be seen from the river, nor can the river be seen from the
site.
Page 97 of 177
414 Nicollet Mall, 414-06 Minneapolis, MN 55401 1-800-895-499xcelenergy.comMounding System:
The mounding of soil around the propane tanks will be used as part of the fire suppression system for
the Sibley Plant. The mounding of soil will be used instead of an overhead sprinkler system, which
due to its complexity requires more rigorous maintenance program. No work will be done in the
Primary Conservation Areas (PCA’s) located on the property. With the exception of increasing the
fenced compound slightly on the east side, all work will be done within the fenced portion of the
facility, all of which exists outside of any PCA. Retaining Wall: The proposed retaining wall will be constructed to limit the amount of grading on site. Without the
retaining wall existing structures would require relocation and the area of disturbance would be
increased, significantly increasing the footprint of the plant. The wall is six feet tall, one foot over the
city’s five feet limit for retaining walls. Without a 6’ tall wall, the mounding system would not
provide the fire suppression needed to meet the NFPA code.
Storm Shelter Foundation:
The storm shelter will consist of a prefabricated building that will be placed on a foundation. The
storm shelter will consist of a shell building within which will be an Emergency Security
Preparedness (ESP) Safety Shelter. This storm shelter will be essential in protecting Xcel Energy
employees and contractors working on the site from severe weather events.
MRCCA Permit:
The mounding of soil over the above ground storage tanks, mitigates the fire risk on the site, keeping
employees and contractors safe. Xcel Energy’s team of designers and engineers worked hard to limit
the footprint of the proposed improvements to lessen any impacts on the risk of impacts to the river
and its ecosystems will be minimal in completing these projects, as all vegetation will remain, no
work will be performed in any PCA’s, and the site is staying fundamentally the same.
Construction Timing: The maintenance and refurbishment of the facility is ongoing. Soil
mounding will occur in spring of 2025.
The proposed improvements are an essential component for the safe operation of the Sibley Plant and
are a part of our commitment to provide safe and reliable natural gas to our customers and help
ensure the safety of Xcel Energy employees, contractors, and the neighboring communities. Thank
you for your consideration of our request to bring the Sibley Plant into compliance with the latest
NFPA safety standards. The proposed improvements will minimally impact the natural environment
and enhance the reliability and safety of the natural gas system in Mendota Heights and surrounding communities. Page 98 of 177

SCALE IN FEET
EROSION & SEDIMENT CONTROL NOTES:
1. INSTALL PERIMETER EROSION CONTROL AT THE LOCATIONS SHOWN ON THE PLANS PRIOR TO THE
COMMENCEMENT OF ANY LAND DISTURBANCE OR CONSTRUCTION ACTIVITIES.
2. BEFORE BEGINNING CONSTRUCTION, INSTALL A TEMPORARY ROCK CONSTRUCTION ENTRANCE AT EACH
POINT WHERE VEHICLES EXIT THE CONSTRUCTION SITE PRIOR TO COMMENCING ANY CLEARING/GRUBBING,
REMOVAL, OR EARTHWORK ACTIVITIES. USE 2 INCH OR GREATER DIAMETER ROCK IN A LAYER AT LEAST 6
INCHES THICK ACROSS THE ENTIRE WIDTH OF THE ENTRANCE. EXTEND THE ROCK ENTRANCE AT LEAST 50
FEET INTO THE CONSTRUCTION ZONE USING A GEO-TEXTILE FABRIC BENEATH THE AGGREGATE TO
PREVENT MIGRATION OF SOIL INTO THE ROCK FROM BELOW.
3. REMOVE ALL SOILS AND SEDIMENTS TRACKED OR OTHERWISE DEPOSITED ONTO PUBLIC AND PRIVATE
PAVEMENT AREAS. AT A MINIMUM REMOVAL SHALL BE ONCE DAILY. SWEEPING SHALL BE MAINTAINED
THROUGHOUT THE DURATION OF THE CONSTRUCTION AND DONE IN A MANNER TO PREVENT DUST BEING
BLOWN TO ADJACENT PROPERTIES.
4. INSTALL INLET PROTECTION AT ALL CATCH BASIN INLETS WHICH RECEIVE RUNOFF FROM THE DISTURBED
AREAS. CONTRACTOR SHALL CLEAN, REMOVE SEDIMENT, OR REPLACE STORM DRAIN INLET PROTECTION
DEVICES ON A ROUTINE BASIS SUCH THAT THE DEVICES ARE FULLY FUNCTIONAL FOR THE NEXT RAIN
EVENT. SEDIMENT DEPOSITED IN AND/OR PLUGGING DRAINAGE SYSTEMS IS THE RESPONSIBILITY OF THE
CONTRACTOR. HAY BALES OR FILTER FABRIC WRAPPED GRATES ARE NOT ALLOWED FOR INLET
PROTECTION.
5. LOCATE SOIL OR DIRT STOCKPILES NO LESS THAN 25 FEET FROM ANY DRAINAGE CHANNEL. IF REMAINING
FOR MORE THAN SEVEN DAYS, STABILIZE THE STOCKPILES BY MULCHING, VEGETATIVE COVER, TARPS, OR
OTHER MEANS. CONTROL EROSION FROM ALL STOCKPILES BY PLACING SILT BARRIERS AROUND THE PILES.
6. MAINTAIN ALL TEMPORARY EROSION AND SEDIMENT CONTROL DEVICES IN PLACE UNTIL THE CONTRIBUTING
DRAINAGE AREA HAS BEEN STABILIZED. INSPECT TEMPORARY EROSION AND SEDIMENT CONTROL DEVICES
ON A DAILY BASIS AND REPLACE DETERIORATED, DAMAGED, OR ROTTED EROSION CONTROL DEVICES
IMMEDIATELY.
7. TEMPORARILY OR PERMANENTLY STABILIZE ALL CONSTRUCTION AREAS WHICH HAVE UNDERGONE FINAL
GRADING, AND ALL AREAS IN WHICH GRADING OR SITE BUILDING CONSTRUCTION OPERATIONS ARE NOT
ACTIVELY UNDERWAY AGAINST EROSION DUE TO RAIN, WIND AND RUNNING WATER. STABILIZATION TO
BEGIN IMMEDIATELY AND BE COMPLETED WITHIN 7 DAYS. USE SEED AND MULCH, EROSION CONTROL
MATTIING, AND/OR SODDING AND STAKING IN GREEN SPACE AREAS. REMOVE ALL TEMPORARY SYNTHETIC,
STRUCTURAL, NON-BIODEGRADABLE EROSION AND SEDIMENT CONTROL DEVICES AFTER THE SITE HAS
UNDERGONE FINAL STABILIZATION WITH PERMANENT VEGETATION ESTABLISHMENT. FINAL STABILIZATION
FOR PURPOSES OF THIS REMOVAL IS 70% ESTABLISHED COVER OVER DENUDED AREA.
8. CHANGES TO APPROVED EROSION CONTROL PLAN MUST BE APPROVED BY THE ENGINEER PRIOR TO
IMPLEMENTATION. CONTRACTOR TO PROVIDE INSTALLATION AND DETAILS FOR ALL PROPOSED ALTERNATE
TYPE DEVICES.
9. IF DEWATERING OR PUMPING OF WATER IS NECESSARY, THE CONTRACTOR IS RESPONSIBLE FOR
OBTAINING ANY NECESSARY PERMITS AND/OR APPROVALS PRIOR TO DISCHARGE OF ANY WATER FROM THE
SITE. IF THE DISCHARGE FROM THE DEWATERING OR PUMPING PROCESS IS TURBID OR CONTAINS
SEDIMENT LADEN WATER, IT MUST BE TREATED THROUGH THE USE OF SEDIMENT TRAPS, VEGETATIVE
FILTER STRIPS, FILTER BAGS (PUMP-IT TUBE DEWATERING BAGS OR EQUAL), OR OTHER SEDIMENT
REDUCING MEASURES SUCH THAT THE DISCHARGE IS NOT VISIBLY DIFFERENT FROM THE RECEIVING
WATER. ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED AT THE DISCHARGE POINT TO
PREVENT SCOUR EROSION.
10. PLACE EROSION CONTROL BLANKET ON ALL DISTURBED AREAS. EROSION CONTROL BLANKET MUST BE
2-SIDED WITH NATURAL NETTING, MEETING MnDOT SPECIFICATIONS.
11. FINAL GRADING SHOWN ON CIVIL SHEETS.
12. DOWNSLOPE ARMORING AT STORM SEWER OUTFALL SHALL BE CONSTRUCTED IN SEMI-DRY CONDITIONS. IF
THE FEATURE IS NOT ABLE TO BE CONSTRUCTIED AND STABILIZED WITH ARMORING IN A SINGLE DAY,
EROSION CONTROL BLANKET SHALL BE PLACED OVER ANY DISTURBED CHANNEL AREAS UNTIL WORK
RESUMES.

EXCERPT FROM DRAFT/UNAPPROVED 9/24/24 PLANNING
COMMISSION MINUTES
PLANNING CASE 2024-17
XCEL ENERGY, 800 SIBLEY MEMORIAL HIGHWAY – MRCCA PERMIT AND AMENDED
CUP
Community Development Manager Sarah Madden explained that Xcel Energy is seeking approval
of a Mississippi River Corridor Critical Area (MRCCA) Permit and Conditional Use
Permit (CUP), in order to implement a number of improvements to the Sibley Propane
Plant facility, located at 800 Sibley Memorial Highway.
Hearing notices were published and mailed to all properties within 350-ft. of the site; no comments
or objections to this request were received.
Community Development Manager Sarah Madden provided a planning staff report and a
presentation on this planning item to the Commission (which is available for viewing
through the City’s website).
Staff recommended approval of this application based on the findings and with conditions.
Commissioner Corbett asked for details on the height of the retaining wall as the presentation
mentioned six feet, but the plans show eight feet. He noted that it does appear that a fence
is being installed on top of the retaining wall for safety.
Community Development Manager Sarah Madden stated that the applicant may be able to provide
clarification on that as there may be a different measurement from the base of the retaining
wall.
Commissioner Katz referenced the statement that the applicants would likely need an NPDES
permit and asked if that would be required.
Community Development Manager Sarah Madden replied that generally with this level of
disturbance that permit would be required.
Chair Field opened the public hearing.
Brian Sullivan, Xcel Energy, explained that they are attempting to bring the current facility up to
code to make sure it is safe and reliable. He stated that after they attempted to implement
the updated fire suppression system that was mentioned in the last permit request, they
determined that there is a better system they would like to use that is much more reliable.
He stated that from the ground elevation up, the retaining wall would be six feet, with safety
railings. He stated that there is foundation work that would be under the ground level,
which is perhaps what was causing confusion on the plans. He stated that a storm shelter
has also been added to the site and they have been busy cleaning and painting the tanks.
Page 147 of 177
DRAFT/UNAPPROVED MINUTES
Commissioner Petschel asked how maintenance is done long-term if the tanks are buried, or
whether that would prohibit the need for maintenance.
Corey Tellers, Project Manager, commented that they are doing extensive checks on the tank and
completing welds where needed for reinforcement. He stated that they will then have a set
schedule to empty the tanks and go inside to do wall thickness checks.
Tom Muck, 1396 Farmdale, referenced the public hearing that occurred two years ago where
there was controversy about the water line that was going to be installed. He stated that
the trees that are in place are critical for the homeowners because of the screening that
those provide. He stated that the City Council approved the trenchless boring for the
installation of the waterline and noted that an alternate method would require a new
MRCCA permit. He wanted to ensure that was still the plan because the trees are very
important to the residents.
George Sonnen, 1387 Farmdale, asked if a permit has been obtained for the road to the south
because there was work on that last week. He stated that the applicant wants to put a new
road in off 13 between the current eastern fence and the tree line and asked if that is 25
feet wide.
Commissioner Corbett was unsure if that was part of this request as he is confused by the
questions. He stated that in the southeast corner the road already exists and they are
bumping a fence out.
Mr. Sonnen stated that he noticed gravel being put down. He stated that he was concerned that if
firetrucks could be brought in, other trucks could come in there as well.
Commissioner Petschel stated that Xcel does bring tanker trucks into the site as well.
Mr. Sonnen replied that those trucks use the access from 13 and clarified that he is speaking of
the dirt road that connects to Farmdale. He stated that he supports the safety and control
improvements but has a question of how much traffic would be using that access.
Mr. Sullivan commented that he has not told anyone to bring dirt into the south fire road.
Commissioner Corbett commented that it looks like an overgrown walking path on the satellite
imaging and was unsure it would be used for tanker trucks.
Mr. Sonnen commented that he would like some trees to be installed so that he does not have to
look at the activity on the site and would like a better review of the road plans.
Commissioner Corbett commented that he did not believe the fire road is part of the scope of
discussion tonight.
Page 148 of 177
DRAFT/UNAPPROVED MINUTES
Chair Field confirmed that the item is not included on the application but noted that the comments
of the resident have been received and are a part of the record. It was confirmed that the
purpose of that road is only for fire access.
Mr. Sullivan commented that there is a fire road that is supposed to be maintained for emergency
access, with an almost trail condition going to Farmdale. He confirmed that the only
purpose of that road/trail is for emergency access.
Another representative from Xcel confirmed that will only be used for fire access and the only
work that would be done on that would be if federal regulation required it to be clearer.
He stated that he would never allow someone to drive back there, other than the
maintenance crew. He identified the small portion of the fence that would be moved. He
stated that if any trees were required to be removed, they would be replaced.
Seeing no one further coming forward wishing to speak, Chair Field asked for a motion to close
the public hearing.

REQUEST FOR CITY COUNCIL ACTION
MEETING DATE: October 1, 2024
AGENDA ITEM: Tabled - Consideration of Ordinance No. 591: Short Term Rentals and
Ordinance No. 594: Fee Schedule Amendment
ITEM TYPE: New and Unfinished Business
DEPARTMENT: Community Development CONTACT: Sarah Madden, Community
Development Manager
ACTION REQUEST:
Adopt Ordinance No. 591, amending Title 3: Business and License regulations to add a new
Chapter 5A: Short Term Rentals; Authorize Publication of Summary Ordinance; and, Adopt
Ordinance No. 594, amending the City’s Fee Schedule by establishing a Short Term Rental
License fee
BACKGROUND:
The City Council met at their September 17, 2024 regular meeting to discuss the proposed
Ordinance No. 591, which would establish regulatory standards and licensing procedures for
Short Term Rentals, also known as ‘vacation rentals’.
The proposed ordinance adds a new chapter into Title 3: Business and License Regulations (to
be identified as Chapter 5A: Short Term Rentals) and is intended to address the short-term
rental of dwelling units within the R-1 one family residential zoning district and provide
operational standards for those residents who are interested in managing a short-term rental
in their home, while also balancing the concerns of neighboring residents and preserving
neighborhood character.
At the September 17 City Council meeting, the Council discussed the ‘primary residence’
requirement, the inspection process, and asked for information on implementation and
enforcement procedures. A public comment letter was also provided to the City Council at the
beginning of the meeting which outlined concerns with the City’s decision to license short-
term rentals and the contents of the proposed ordinance. The City Council directed staff to
make corrections and adjustments to the ordinance based on their discussion and asked for
the City Attorney to review and provide comments to the Council about the letter received in
Page 151 of 177
advance of their next meeting.
The draft of the Short Term Rental ordinance has been updated to reflect comments that were
shared by both members of the public, and members of the City Council during the meeting.
This revised ordinance is included as an attachment to this report. Additionally, the City
Attorney has prepared a memo to the Council which addresses the public comment letter
concerning the Short Term Rental Ordinance.
The revised final draft of the ordinance continues to include the primary policy objectives that
have been discussed by the City Council over the past several months, including the overall
standard defining short-term rentals as having leasing or rental periods of 30 days or less,
property maintenance cross-references, standards for primary residency, maximum bedrooms
and occupancy, a minimum night stay, an inspection requirement, and minimum renter age. In
addition to the formal Ordinance No. 591, a red-lined version of the ordinance has also been
included as an attachment to provide additional clarity on what changes have been made.
The revisions include:
1) Adding an additional section prior to the licensing provisions section which reinforces the
intended requirement for the operator of a short term rental to maintain the dwelling unit as
their primary residence
2) Establishing a timeline for existing operators to obtain their initial license following the
effective date of the ordinance (45 days)
3) Updating the language noting that operators should maintain a guest registry and
clarifying its contents and purpose
4) Including warranty and severability clauses
5) Minor grammatical and spelling error correction as needed
In addition to the proposed Ordinance No. 591, staff has prepared Ordinance No. 594
amending the City’s fee schedule to add a Short Term Rental License fee, which is proposed to
be set at $200.00 per annual license. This has not been modified from the September 17th
meeting.
Due to the length of the proposed ordinance, the City Council is also asked to consider
authorizing the publication of a Summary Ordinance, which requires 4/5ths of the Council’s
votes to succeed. Staff recommends that the City Council approve the new ordinance to
establish a Short Term Rental licensing process, and may make a motion for the consideration
of adoption of the two proposed ordinances as noted below:
(1) Adopt Ordinance No. 591, Amending Title 3 of the City Code to incorporate Chapter 5A:
Short Term Rentals, establishing a short term license and regulatory standards, and Authorize
Publication of a Summary Ordinance; and,
(2) Adopt Ordinance No. 594, Amending the City’s Fee Schedule to add a Short Term Rental
License fee.

ORDINANCE NO. 591
AMENDING TITLE 3 TO CREATE CHAPTER 5A: SHORT TERM RENTALS
The City Council of the City of Mendota Heights does ordain:
Section 1. City Code Title 3 – BUSINESS AND LICENSE REGULATIONS is hereby
amended to add Chapter 5A: SHORT TERM RENTALS as follows:
3-5A-1: PURPOSE AND SCOPE:
It is the purpose of this chapter to assure that short-term rental of dwelling units in the City's R-1
one-family residential zoning district is conducted, operated, and maintained so as not to become
a nuisance to the surrounding neighborhood or an influence that fosters blight and deterioration
or creates a disincentive to reinvest in the community. The City recognizes that short-term
rentals provide an opportunity for residents to use their property to generate supplemental
income; and, when properly managed, short-term rentals have a minimal impact on surrounding
properties. When not properly managed, short-term rentals have the capacity to generate noise,
traffic, and trash beyond what is typically present in a residential neighborhood creating a
nuisance. These issues can be especially acute when the owner of the property does not reside in
the home. In order to promote the health, safety, general welfare, aesthetics, and image of the
community, the City facilitates and regulates the use of residential properties for short-term
rentals by requiring the licensure of short-term rentals.
3-5A-2: DEFINITIONS:
For the purpose of this chapter, the following terms shall be defined as set forth below:
BEDROOM: A habitable room within a single-family dwelling which is used, or intended to be
used, primarily for the purpose of sleeping, but shall not include any kitchen or dining room. The
room shall have a method of egress in addition to the primary entry door to the room in
accordance with the Minnesota Residential Building Code.
DWELLING: A building or one or more portions thereof occupied or intended to be occupied
for residential purposes; but not including rooms in motels, hotels, nursing homes, boarding
houses, tents and recreational vehicles, or attached multiple- family dwellings.
DWELLING UNIT: A residential accommodation located within a dwelling that includes
permanently installed cooking, sleeping, and sanitation facilities, designed or intended for use as
living quarters for a single family. Dwelling units subject to this chapter are defined as being
detached dwelling units in the R-1 one-family zoning district.
OCCUPANT: A person who lives or sleeps in a dwelling unit.

TO: MENDOTA HEIGHTS CITY COUNCIL
FROM: AMY SCHMIDT, CITY ATTORNEY
DATE: SEPTEMBER 24, 2024
RE: SHORT-TERM RENTAL ORDINANCE; MEMO FROM LUKE BELLVILLE
Mayor and Councilmembers,
On September 17, 2024, the City Council conducted a public hearing and considered a proposed
ordinance regulating short-term rental of residential property in the City (the “Ordinance”). Just
prior to that meeting, the City Council received a memo from Luke Bellville, a Minnesota attorney.
In his memo, Mr. Bellville identified the following:
Legal Issues
1. Affidavit of Residency Requirement
2. Age Discrimination
3. Due Process Concerns
4. Municipal Authority
5. Enforcement and Compliance Burden
6. Privacy Concerns
For each category, he described his view of the associated legal issues and cited caselaw, state and
federal law, and the Minnesota and United States constitutions; and identified general legal
considerations or potential conflicts.
Following the public hearing and at the conclusion of the Council’s consideration of the proposed
Ordinance, the Council voted to table the matter for a final decision on October 1, 2024, and
requested a legal memo to address the issues raised by Mr. Bellville.
Short Answer
The issues presented by Mr. Bellville warrant consideration by the Council, and his summary is
helpful in identifying a need for certain revisions to the proposed Ordinance. At the same time,
the scope of the legal concerns raised and the various legal authorities cited tend to overstate any
legal defects in the proposed Ordinance. While it is not possible to say that any ordinance would
definitely survive any possible legal challenge, with a few revisions made to the proposed
Ordinance, it is likely to survive a legal challenge in whole or in part.
Discussion
Generally speaking, the concerns and issues raised by Mr. Bellville are not without merit. Clearly,
the City is obligated to adopt ordinances that are constitutional, and do not discriminate or conflict
Page 173 of 177
2
232781v1
with other state or federal law. However, the specific issues that Mr. Bellville identifies, and the
legal sources that he points to, are not necessarily the applicable legal analysis for the proposed
Ordinance.
1. Municipal Authority to Adopt Short-Term Rental Ordinance.
In his memo, Mr. Bellville states the following:
The extensive regulations and requirements for licensure might be seen as an
overreach of municipal authority. While Minnesota is a home rule state (Minn.
Const. art. XII, § 4), there are limits to municipal power.
•Relevant Statute: Minn. Stat.§ 462.351 grants municipalities the authority
to regulate land use, but this power must be exercised within constitutional
limits.
While it is true that there are limits to municipal power, this perhaps is a misreading of the
Constitutional provision. Article XII, Section 4 of the Minnesota Constitution authorizes “any
local government unit” to “adopt a home rule charter for its government.” It is not clear how this
makes Minnesota a “home rule state.” Notably, the City of Mendota Heights has not adopted a
home rule charter, and exercises powers as a statutory city. Accordingly, this part of the Minnesota
Constitution is not specifically relevant to the question of the authority of the City of Mendota
Heights to adopt this Ordinance.
Minnesota Statutes § 462.351 is likewise not specifically relevant in this context. This Statute
section applies to a city’s authority related to municipal planning, and in combination with other
sections1 has the stated purpose of providing “municipalities, in a single body of law, with the
necessary powers and a uniform procedure for adequately conducting and implementing municipal
planning.”
Here, the proposed Ordinance does not fall under the City’s exercise of its municipal planning
powers. Rather, by regulating short-term rentals, the City Council is exercising its general
authority to issue licenses. This general authority arises from the powers granted by the Legislature
to a city council to:
provide for the government and good order of the city, the suppression of vice and
immorality, the prevention of crime, the protection of public and private property,
the benefit of residence, trade, and commerce, and the promotion of health, safety,
order, convenience, and the general welfare by such ordinances not inconsistent
with the Constitution and laws of the United States or of this state as it shall deem
expedient.2
1 Minn. Stat. § § 462.351-462.364.
2 Minn. Stat. § 412.221, subd. 32 (emphasis added). See also, City of St. Paul v. Dalsin, 245 Minn. 325, 71 N.W.2d
855 (1955); State v. United Parking Stations, 235, Minn. 147, 50 N.W.2d 50 (1951).

2. Other Constitutional Concerns.
Please note that each of the following constitutional issues could each be addressed far more
extensively than is outlined here. I am happy to provide more in-depth analysis if needed.
A. General Constitutionality.
In addition to the concerns related to municipal authority to regulate the short-term rental of
property under the Minnesota Constitution, in his memo, Mr. Bellville raises additional concerns
regarding the constitutionality of this type of regulation. Specifically, Mr. Bellville asserts that a
requirement for an affidavit of residency could “infringe on property rights protected under the
Fifth and Fourteenth Amendments to the U.S. Constitution.” In support of this concern, Mr.
Bellville cites an inverse condemnation3 case4 where he says the Court “emphasized the
importance of considering the ‘reasonable expectations’ of property owners when evaluating
regulations affecting property rights.”
This is an incomplete description of the Court’s holding in the cited case. The Court, in upholding
the government’s action, also recognized that governments have “well-established power to
‘adjus[t] rights for the public good.’”5 Also, it is unclear how the holding or analysis of this case
specifically relates to the constitutionality of a requirement in the Ordinance that a license applicant
submit an affidavit of residency, or that a licensee may face the possible revocation of a license
based on non-residency.
B. Enforcement and Compliance Burden.
Related to this case cited above, Mr. Bellville also expresses concern that the “significant
responsibility placed on property owners to manage their rentals and comply with various
conditions could be burdensome and potentially discourage participation in short-term rentals.”
He cites Penn Central Transportation Co. v. City of New York, a seminal inverse condemnation
case. Mr. Bellville cites this case as a possible basis for a challenge to “overly burdensome
regulations” that violate the “reasonable use” doctrine established in that case.
Under the Penn Central rubric, a court would look at a regulation in terms of “the economic impact
of the regulation on the claimant and, particularly, the extent to which the regulation has interfered
with distinct investment-backed expectations . . . [and] the character of the governmental action.”6
While this legal test has evolved since it was initially decided7, it does still stand for the proposition
that if a government regulation goes so far as to deny an owner of all economic value in the affected
property, the regulation would effectively be a taking.
3 In simple terms, “inverse condemnation” occurs when a government regulation of land is so restrictive that the land
is deprived of all economic value or use such that the regulation has the same effect as an exercise of eminent domain,
and as a result, an owner is entitled to just compensation.
4 Murr v. Wisconsin, 237 S. Ct. 1933 (2017).
5 Id. at 1943 (citations omitted).
6 Penn Central Transportation Co. v. City of New York, 438 U.S. 104. 138 (1978).
7 See, e.g., Kaiser Aetna v. United States, 44 U.S. 164 (1979).

232781v1
As with the issue discussed above, the regulations at issue in the case were not related to licensing,
and were far more onerous and limiting than those in the proposed Ordinance. In fact, with the
proposed Ordinance, the performance standards and management requirements are likely in the
interests of an owner who wishes to protect their investment or receive good ratings and reviews
from their renters or the platforms where they advertise their property for short-term rental.
Further, all owners—regardless of whether they rent their property—are required to comply with
the City Property Maintenance Code, the State Building Code, and other applicable regulations.
Imposing restrictions under the City’s licensing authority is not so onerous as to constitute a taking.
C. Due Process.
As an additional constitutional concern, Mr. Bellville also states that the “revocation of licenses
after violations . . . could face due process challenges under the Fourteenth Amendment if the
process for contesting violations is not sufficiently robust.” In support of this concern, he cites a
case where the Court established a “balancing test” for determining the due process that must be
provided in administrative hearings.8
Again, this case is not necessarily the most apt choice of law in this context. First, the case cited
is not a licensing case, and was a matter related to a denial of Social Security benefits. Second,
while the cited case might be one of the leading cases related to the requirements for due process
in administrative hearings, there is actually a division of opinion among the Courts as to whether
licensees are entitled to due process.9 It is generally agreed that due process is required if a
licensee has a property interest or a fundamental interest in the granting, renewal, or transfer of a
license.10 Where due process is required for a licensee, there are generally-accepted steps that a
city should follow to ensure that the licensee’s rights are protected.11 As drafted, the proposed
Ordinance conforms to these steps.
D. Equal Protection (Age Discrimination).
As drafted, the proposed Ordinance prohibits a licensee from renting to anyone under the age of
25 years. In his memo, Mr. Bellville notes concerns that this prohibition could violate state or
federal law as illegal age discrimination. Mr. Bellville acknowledges that age is not a protected
class under either the Federal Fair Housing Act or the Minnesota Human Rights Act as it applies
to real property. At the same time, while citing cases that he acknowledges as “not directly
applicable” for this purpose, Mr. Bellville also asserts that the proposed Ordinance could be
challenged under the Federal Fair Housing Act or face other Equal Protection claims.12
8 Mathews v. Eldridge, 424 U.S. 319 (1976)
9 See, e.g., Klinger v. City of Braham, 130 F. Supp.2d 1068 (D. Minn. 2001).
10 Greater Duluth COACT v. City of Duluth, 701 F. Supp. 1452 (D. Minn. 1988).
11 Id; Sabes v. City of Minneapolis, 265 Minn. 166, 120 N.W.2d 871 (1963); State v. City of Duluth, 125 Minn. 425,
147 N.W. 820 (1914); Trumbull Div., OwensCorning Fiberglass Corp. v. City of Minneapolis, 445 F. Supp. 911, 917
(D. Minn. 1978; In re License of West Side Pawn, 587 N.W.2d 521 (Minn. Ct. App. 1998); Hymanson and Lucky
Lanes Inc. v. City of St. Paul, 329 N.W.2d 324 (Minn. 1983).
12 Cases cited are related to zoning; discrimination in housing rental under Section 8; conscientious objector seeking
discharge from the Army (Vietnam era); discrimination under the Age Discrimination in Employment Act.

232781v1
None of the cited legal authority really apply in the context of the proposed Ordinance. Here, as
an exercise of the City’s powers to issue licenses, it is within the City’s authority to establish a
minimum age for short-term rentals in furtherance of the public interest to protect life, safety,
general welfare, and health. For example, before the Legislature raised the state-wide minimum
age for the purchase of tobacco to 21 years, many Minnesota cities adopted local ordinances
establishing that same minimum age for sales by city tobacco licensees.
E. Conclusion regarding Constitutional Concerns.
As cited above, Minnesota Statutes § 412.221, subd. 32, explicitly requires that city ordinances
adopted under this grant of power be consistent with state and federal laws and constitutions. As
a general rule, ordinances are presumed to be constitutional, and a person challenging the
constitutionality of an ordinance bears the legal burden of proving that it is unconstitutional.13
Here, the requirements throughout the proposed Ordinance serve the Council’s interest in
regulating for the protection of life, safety, general welfare, and health of persons and property in
the City. While it is possible that a person could bring challenges against the proposed Ordinance,
there is nothing in the constitution, statutes, or court cases addressed above that are a clear basis
for invalidating the proposed Ordinance.
3. Privacy Concerns.
Last, the proposed Ordinance includes requirement that a licensee maintain a guest registry as a
condition of the license. Mr. Bellville raises the concern that such a registry could be public data
under the Minnesota Government Data Practices Act (“MGDPA”). As the Council is no doubt
aware, the MGDPA defines “government data” as “all data collected, created, received, maintained
or disseminated by any government entity regardless of its physical form, storage media or
conditions of use.”14 The MGDPA “establishes a presumption that government data are public
and are accessible by the public for both inspection and copying unless there is federal law, a state
statute, or a temporary classification of data that provides that certain data are not public.”15
As the proposed Ordinance is written, it is not explicit that a licensee must submit the required
guest registry to the City for any purpose, or that the data will ever be in the possession of the City.
Accordingly, the concern Mr. Bellville raises points to a need for clarification in the proposed
Ordinance. With some revisions, this legal concern can be mitigated.
Conclusion
With some provisions specifically tailored to the needs and character of the City of Mendota
Heights, the proposed Ordinance is similar to other short-term rental ordinances across Minnesota.
The Council has the legal authority to adopt and enforce the Ordinance. The Ordinance
requirements imposed on licensees are not so onerous or burdensome as to be deemed a taking, or
to be a violation of a licensee applicant’s or a licensee’s constitutional rights.
