Proposal
Leafline Labs, LLC (Applicant), has submitted an application requesting a Site Plan Review and
Conditional Use Permit to allow for the construction of an approximate 134,000 square foot addi-
tion, in two phases, to their existing 43,700 square foot facility at 8235 97th Street South. The
proposed addition would be traditional construction as opposed to the greenhouse construction
as approved in 2020 (Resolution 2020-027). CUP and Site Plan approvals are in effect for one
calendar year before expiring. The Applicant requested an extension to their 2020 CUP and Site
Plan approval extending the action date to February 2023. therefore, the 2020 approval continues
to be in effect; however, the adjustment of the construction type from greenhouse to traditional
requires an amendment to the approvals.

Background
The existing Leafline Labs facility was approved and constructed in 2014, following Minnesota’s
legalization of the production and use of cannabis for some medical purposes. Leafline Labs was
selected as a manufacturer by the Minnesota Department of Health (MDH) as one of two licensed

medical cannabis producers in Minnesota. The current facility houses growing and processing
functions for the company’s medical cannabis products. The approved site plan in 2014 planned
for a future expansion on the site. In 2020, Leafline Labs proposed to increase their production
capacities with a 134,000 square foot greenhouse expansion in response the State’s medical
cannabis program expansions, although they halted moving forward due to the onset of the
pandemic.
Planning Considerations
Land Use
The parcel at 8235 97th Street South is located within the Cottage Grove Business Park and is
zoned I-2, General Industry. Pharmaceutical manufacturing is a conditionally permitted use within
this zoning district.
Existing Conditions
During initial development of this site in 2015, the entire parcel was graded anticipating future
growth. A tree inventory was conducted, and any trees removed were mitigated with trees planted
on site in 2015. A gravel pad was installed in the area of the future phased expansion; therefore,
the proposed expansion does not require mass site grading or alteration to the existing landscape.
Existing Site
Proposed Site Plan
The Applicant received approval for expansion of their operations with construction of an approx-
imate 134,000 square foot greenhouse. With the onset of the pandemic, the Applicant did not
move forward with the expansion. Since that time, the Applicant has indicated a traditional con-
struction expansion would support their needs for their increased operations. The Applicant is
proposing an expansion in two phases. The first phase would be construction of a 70,000 square
foot addition to their existing facility, which would include flower rooms, vegetation rooms, mother
rooms, industrial irrigation, energy conscious control systems, packaging, and production rooms
as well as additional restroom facilities and breakrooms.

Building Materials
The City’s Zoning Code Title 11-6-13C, Nonresidential Structures, requires all new structures to
use a minimum of 65 percent Class I materials. These materials include glass and window panels,
brick, and natural stone. This requirement results in high quality development and the use of
materials that will resist deterioration.
The Applicant’s proposed addition in 2020 was planned as a prefabricated greenhouse structure,
with glass walls and roof panels. Given the lack of strong sunlight in the Minnesota region and the
potential lack of quality of product, the Applicant has revised their design to precast tip up panels.
The proposed panels would be separated by aluminum rain screen on each of the corners and
would be painted to match the existing structure. The proposed building would meet the City’s
minimum material requirements and breakup of the façade.
Building Rendering
Parking
Ordinance requirements for parking on the site are based on the mix of uses contained in the
existing and proposed buildings. The existing building houses office, manufacturing, and ware-
housing activities. Parking requirements per the City’s Zoning Code Title 11-3-9 are 1 space per
250 square feet of office space, 1 space per 400 square feet of manufacturing space, and 4
spaces plus 1 space per 2,000 square feet of warehousing. The mix of uses in the existing building
requires a total of approximately 111 spaces. The Applicant constructed 102 spaces in 2014 with
construction of their existing facility. The reduced number of spaces was approved given the min-
imal traffic to the site. The Applicant did provide proof of parking to ensure additional parking could
be added to the site, if necessary, to support operations.
The proposed Phase 1 addition is approximately 70,000 square feet, with a future Phase 2 includ-
ing another 67,000 square foot addition. The Applicant has proposed an additional 15 parking
spaces with the first phase of their expansion and an additional 133 spaces at time of construction
of the second phase of their expansion. Proof of parking of 55 stalls is also provided, if required
to support operations in the future. Staff has verified operations on site have not required addi-
tional parking spaces above and beyond the existing spaces on the site.

Current, Phase 1, and Phase 2 Parking Areas
Traffic/Access
The facility currently employs 48 staff members at the site. The Applicant estimates the Phase 1
expansion will require the addition of 60 employees and the Phase 2 expansion will require an
additional 120 employees, for a total of 228 employees at full buildout. The Applicant has noted,
given the separate shifts, they do not anticipate needing to provide all proposed proof of parking
or access adjustments to support the additional employees as part of Phase 1. The Applicant is
proposing additional parking as part of Phase 2.
The site’s two current access roads from 97th Street will be preserved. The proposed addition
includes the extension of the site’s internal access road around the perimeter of the Phase 1 and
Phase 2 expansion for fire safety purposes. The current access is adjacent to the existing facility
and will be rerouted to the west as part of Phase 1. This access road is required to be paved as
part of Phase 1.

Surface Water Management/Grading
Surface water management infrastructure installed at the time of the 2014 development of the site
was sized to accommodate the maximum future site development, including the full buildout of
the site’s parking capacity. The proposed expansion does not fully exhaust their maximum capac-
ity, and therefore does not cause any additional stormwater management infrastructure to be
required beyond the existing infrastructure.
Existing Storm Basin Locations
Tree Preservation/Landscaping
A tree inventory was completed at the time of initial development (approved landscaping plan
dated 4/10/2015), identifying 409 qualifying trees on the site, of which 201 were removed and 208
preserved. Under the tree preservation ordinance at that time (Title 11-6-6), this level of removal
was determined to exceed the permitted removal threshold. The excess removed trees were
required to be mitigated with 82 replacement trees.
Additionally, the landscaping ordinance at the time (Title 11-6-5), which has since been amended,
required that the site, with an area of 914,394 square feet, excluding stormwater basins, be
planted with 132 overstory deciduous trees and 123 coniferous trees. Under the terms of the
landscaping ordinance at that time, preserved trees could be counted toward landscaping require-
ments at a rate of 1 preserved tree to 2 required trees. The 208 preserved trees were determined
to account for up to 416 required new trees. The Applicant has fulfilled the City’s landscaping
requirements with the large number of trees remaining on the site, along with the additional tree

plantings in 2015 along the south boundary, around the building, and the entrance as part of the
building in 2015.
The Applicant is proposing planting of 24 trees and 279 shrubs as part of Phase 1 of the expan-
sion. Prior to the issuance of a building permit, an updated landscape plan will be required to be
submitted ensuring the proposed tree plantings do not impact the utilities or easement areas.
Phase 1 Landscape Plan
Odor Mitigation
As a part of the approval in 2014, the Applicant indicated they would provide appropriate odor
mitigation control system as well as an odor mitigation plan. The system they installed included a
carbon filter within their exhaust system to avoid noxious odors or creating dangers to people
within the vicinity. The odor mitigation plan requires monitoring of odor in three locations: within
the exhaust stack, just outside the building, and at the property line. The mitigation plan also
allows the City the ability to take odor measurements at any time within the facility or property. In
the City’s letter dated February 3, 2016, the Applicant is required to notify the City if a nasal ranger
reading is above 2 dilution-to-threshold (D/T, odor concentration in the air) or “a just noticeable
odor” is detected at either location 2 or 3 on the below monitoring location map. If a nasal ranger
reading is at or above 4 D/T, the property owner is required to replace the carbon filters as a part
of the odor mitigation system.

Monitoring Location Map
The Applicant has indicated the previously proposed greenhouse expansion would not be condu-
cive to their operations and pose additional concerns including the lack of strong odor control,
poor energy efficiency, and potential security threats; therefore, the proposed traditional construc-
tion provides a more secure facility and the ability to manage potential nuisances from operations.
Any complaint received regarding odor from the facility will require immediate response from the
property owner to mitigate the nuisance. To date, City staff has not received any odor complaints
related to the facility and the operations. Staff will continue to monitor the odor data provided bi-
annually from the Applicant.
Utilities
The subject property is located within the Metropolitan Urban Service Area (MUSA). Prior to the
release of the building permit, public drainage and utility easements shall be dedicated over all
surface water storage, cross site conveyance routes, and underground water utility infrastructure.
Development Fees
Development fees for the entire site were paid at the time of initial development. The proposed
expansion does not trigger additional development fees.

Cottage Grove, MN 55016
Leafline Labs is looking to amend their prior Special Use Permit approved in 2019 from a greenhouse
structural to a traditional structure matching the existing 47,000 sqft facility. Upon further review of the
greenhouse structure originally submitted on, Leafline Labs has concluded that continuing with this plan
would not be the best option and instead proposes expanding the current facility with an additional
70,000 sqft structure of indoor agricultural space matching the existing.
The use of a greenhouse structure for medicinal cannabis in the Minnesota region would not be
would pose not only
issues with our operations, but also likely disappointment from our patients for the lack of quality
medicinal cannabis. Greenhouse structures also pose more concerns for Leafline, such as:
Lack of strong odor control
Large swings in Environmental controls
Poor Energy Efficiency
Major security threats and access control
For the reasons mentioned above, Leafline Labs strongly believes that the only approach to
combating these concerns is to build a new precast concrete structure matching the existing. The new
structure would not only provide strong odor controls and tight environmental controls, but it would
indeed strengthen our already profound security surveillance and controlled access to our cultivation
spaces. This new structure will be greatly more energy efficient- furthering our beliefs in a sustainable
Earth while being more aesthetically pleasing to our friends and neighbors. The proposed 70,000 sqft
addition would be home to our new and improved cultivation area that would include:
(9) double stack Flower rooms with LED lighting with state-of-the-art mechanical/HVAC systems
(2) Vegetation rooms with LED lighting
(2) Mother rooms
Industrial Irrigation room to water all the plants with energy conscious control systems
Dual purpose Production and Packaging rooms
All of the above-mentioned areas would be inclusive of state-of-the-art HVAC, lighting, controls, and
industrial systems to aid Leafline Labs in providing our patients with the best quality medicinal cannabis
on the market.

RE: CONDITIONAL USE PERMIT & SITE PLAN APPLICATION NARRATIVE
TH
8235 97 STREET SOUTH
Emily,
Enclosed is a Conditional Use Permit and Site Plan application and the supporting documents for the Leafline Labs
th
property at 8235 97 Street South. The specific request is to approve a Conditional Use Permit (CUP) for building
additions (in two Phases) to support additional grow facilities/operations, and secondly for Site Plan approval for the
Phase 1 building expansion.
The subject site is known as Block 1 Lot 1 GLENGROVE INDUSTRIAL PARK 4TH ADDITION, Parcel
2102721330003 and is 21.84 acres in size. Leafline Labs received a CUP/Site Plan approval from the City in
January 2020 for a new greenhouse building for growing operations. However, that was not completed, and the
CUP/Site Plan approval have expired. This request is similar to the proposal approved in 2020 for additional grow
facility space and supporting operations, but the architectural style would not be a greenhouse but more of an
office/industrial pre-cast concrete building instead. Leafline Labs has provided a more detailed summary of the
business operations and explanation to the changes from the original CUP approval. This is included with the
supporting documents in the submittal.
The enclosed plans provide full detail of the site layout and architectural design of the building additions. Below is a
description of the proposal and how the project addresses the Conditional Use Permit criteria.
SITE PLAN + PROJECT DESCRIPTION
th
The Leafline Labs property at 8235 97 Street South operates as one of the state licensed marijuana grow facilities.
The proposal is to add more growing facilities to the east of the existing building, completed in two phases. Phase 1
would consist of a building that is 70,940 SF and the Phase 2 building would be 66,500 SF. With both building
phases completed, the overall site would consist of 19% building footprint, 27% parking lot/sidewalks, and 54%
open space.
th
Access to the site would remain unchanged with the two access points north of the property from 97 Street South.
In the Site Plan set, Sheet C3-10 identifies each building phase and the parking spaces that would be provided with
each phase to show the parking complies with the code requirements. Parking provided for Phase 1 and Phase 2 is
based on employee counts provided by the owner. Future parking areas have been designated on the site plan to
provide additional parking to meet code requirements.
Stormwater management for the site was constructed in 2014 with additional capacity to account for future
construction of the site. The total impervious coverage area for the sizing of the stormwater management is
436,955 SF. The proposed coverage for the Phase 1 building, Phase 2 building, parking, access roads, and future
parking as required by code is 435,208 SF. Therefore, the proposed project will not increase the amount of

impervious area to the stormwater management facility for the site. The proposed building and parking areas will
drain to existing inlets on site or tie into existing storm sewer stubbed for future as part of the 2014 plan to maintain
flow patterns on site.
Site utilities for the project will consist of a new sanitary service, watermain, storm sewer, and a new gas service.
Storm sewer will consist of an extension of the existing storm sewer stub to the west along the north side of the
proposed building to tie in roof drain connections. There will also be a new inlet and trench drain at the loading
docks near the southeast corner of the proposed building which will tie into an existing catch basin. The sanitary

stub to the north of the proposed building and continue to the west and south along the building perimeter to
provide hydrants at appropriate spacing along the fire access road.
The Phase 1 and Phase 2 buildings would be a pre-cast concrete building. Please see the attached letter from the
architect describing the building height and materials in detail.
CONDITIONAL USE PERMIT ORDINANCE CRITERIA
Below are the questions the applicant must answer in response to the Conditional Use Permit (CUP) Ordinance
Criteria, and responses to each question:
A. Will the use be in conformity with the City's Comprehensive Plan and with the purpose, intent, and
applicable standards of the Zoning Ordinance? EXPLAIN.
Response: The 2040 Comprehensive Plan for Cottage Grove identifies this property within the current and
future Industrial land use areas. As such, the existing facility is located properly based on the current land
use designation and the future expansions would be consistent with the area to remain designated for
Industrial uses. The Land Use Chapter of the Comprehensive Plan also states that the subdivision and
zoning standards will emphasize high quality site and architectural design. The proposed plans were
designed following the zoning standards and design guidelines to uphold the high-quality standards of the
Citys vision for this site.
B. The use shall be located, designed, maintained and operated to be compatible with the existing or intended
character of that zoning district in which it is located. How does the proposed use fit these criteria?
Response: The property is zoned I-2, General Industry and the proposed use is classified as Pharmaceutical
Manufacturing, which is permitted with a CUP. The growing operations would be entirely indoors in a new
building that would be architecturally compatible to the existing building on-site and surrounding buildings in
the industrial park. The new building design is more of a traditional building style versus the approved
greenhouse style, and has fewer windows than a greenhouse, decreasing light omitted from the building.
See the attached narrative from Leafline explaining the reasons and benefits switching building styles and
for more details about the operations.
Page 2
952.426.0699 + www.ISGInc.com
C. The use shall not depreciate values of surrounding property. Explain effects of the proposed use on
surrounding property values.
Response: The proposal is to expand the existing use, which has proved to be a well-maintained site and
business operation in the Industrial Park. The use should not have any negative impacts to the property
values as the operations are entirely inside the building and the operations ensure it is a highly secure site
with well trained staff as the only authorized people within the building.
D. The use shall not be hazardous, detrimental, or disturbing to present and potential surrounding land uses
due to noises, glare, smoke, dust, odor, fumes, water pollution vibration, general unsightliness or other
nuisances. Explain effects of proposed use.
Response: The cultivation space operates with a 12 hour on and a 12 hour off lighting cycle. In addition to
that, the cultivation rooms are completely sealed from the rest of the building and especially to the exterior.
Any outside light reaching the plants pose disruption to their growth. This is mitigated by having a very tight
room environment which includes lighting. For the non-cultivation areas, the business operates at one shift
per day and all lighting in the facility is on an environmental-friendly controller to meet Section C408.3 IECC
2018.
There are special carbon filters installed throughout the building to control odor. Please see attached
cutsheets with the additional filters that are included in the building.
E. The use shall generate only minimal vehicular traffic on local streets as defined by the Transportation
Element of the Comprehensive Plan. The use shall not create traffic congestion, unsafe access, or parking
needs that will cause inconveniences to the adjoining properties. Explain the transportation needs for the
proposed use.
Response: Leafline Labs does not anticipate a large increase in truck traffic to the area. There are two
th
existing access points from 97 Street South that will remain the same and are adequate to service the
additional traffic onto the site. Sheet C3-10 of the Site Plan provides details showing that with each building
phase addition there is additional parking to meet the on-site parking needs and code requirements.
F. The use shall be served adequately by essential public services such as streets, police, fire protection and
utilities. Explain how the proposed use will be served.
Response: The public services to this site are adequate to service the proposed expansions. No specific
special needs or conditions are needed for the proposal from any public agency. In the beginning of this
letter the full extent of the utility extension and connections to serve the expansion are identified.
G. The use shall not create excessive additional requirements at public cost for public facilities and services
and shall not be detrimental to the economic welfare of the City. Justify this statement.
Response: The expansion would not cause any detriment to the economic welfare to the city. In addition to
the City regulations, this use is regulated by the Minnesota Department of Health. The Minnesota
Department of Health completes a full audit of the existing security system whenever they please with no

advanced notice, because of these we have to ensure full compliance 24/7. In addition to that, Leafline has
to submit our security/surveillance design for review and approval before any installation can begin. In a
nutshell, there is camera coverage of all interior spaces, all rooms (other then bathrooms) will receive full
video surveillance and coverage. All doors inside the facility have badge access where only permitted
employees who have undergone the proper security training are authorized into each respective room- on
top of that, all exterior doors are under video surveillance from the interior and exterior 24/7 with door
contacts and motion sensors.
The perimeter of the building has full camera coverage with face recognition and infrared cameras. In the
event of a power outage, all security systems and data are on emergency backup power
and Uninterruptible Power Supply's (UPS) to ensure no video coverage is lost. These additional security
measures ensure that there are no security issues and ensure the business operates safely and securely at
all times. This also ensures the site and use are good neighbors to the surrounding properties and to the
City for their benefit as well.
H. The use shall preserve and incorporate the site's important natural and scenic features into the
development of adjacent vacant land. Will these criteria be met?
Response: With the Phase 1 and Phase 2 building additions, the site would still be comprised of 54% open
space. The open space serves to provide water quality, buffering to adjacent properties, and areas to
landscape for additional screening and aesthetic enhancement to the site and area.
I.The use shall cause minimal adverse environmental effects. List any effects.
Response: The watering system used inside the building is with an energy conscious control systems. The
lights will be LED. These additional features along with the pre-cast concrete instead of the greenhouse will
help the building operate more efficiently than the previously approved greenhouse addition.
In addition, Stormwater management for the site was constructed in 2014 with additional capacity to
account for future construction and provide for water quality measures. The proposed building and parking
areas will drain to existing inlets on site or tie into existing storm sewer stubbed and provide adequate sizing
to accommodate the proposed expansion stormwater needs.
J. The use shall not adversely affect the potential development of adjacent vacant land. List any potential
problems.
Response: The proposed buildings and use would not adversely affect any future development on adjacent
lots. The use is consistent with the uses of the I-2 zoning and the site design complies with high, setbacks,
parking and other zoning regulations, the building is architecturally compatible to maintain the character of
the area.
