SUMMARY
Applicant &
Property Owner: Hawkins, Inc.
Location: 13005 Courthouse Blvd
Site Area in Acres: 27.86 Acres
Surrounding Land Uses: North: HI – Heavy Industrial/GI – General Industrial
East: GI – General Industrial
South: GI – General Industrial
West: HI – Heavy Industrial/GI – General Industrial
Existing Zoning District: HI – Heavy Industrial
Comprehensive Plan Desig.: HI – Heavy Industrial
The Planning Commission is being asked to conduct a site plan and building design review for
Hawkins, Inc. to allow for the construction of two additions totaling 47,000 square feet onto the
existing manufacturing and warehouse building onsite at 13005 Courthouse Blvd in eastern
Rosemount. Hawkins, Inc. is a chemical company that produces dilutes, and/or repackages
chemicals including acids and bases, and the proposed site improvements will not result in any
changes to the current operations within the facility, and will instead provide additional space that
was originally planned back when the planned unit development final site and building plan for the
property was approved by the City Council in 2011. Staff is recommending approval of the request
subject to the conditions of approval listed in this report.
BACKGROUND
In 2011, Hawkins, Inc., had purchased land from CNR that is approximately 25 acres in size to
construct a 62,640 square foot building to manufacture and warehouse chemicals. The site is
approximately 800 feet deep and 1,400 feet wide and is located between the MN Highway 52 and
Highway 55 split. The site then included CNR office and lab buildings, parking lot area, and the
northern site access. All other CNR structures on the site were proposed to be demolished except
for one 44-foot diameter and 34-foot-tall cylinder tank that was relocated to the tank farm area on
the central portion of the site. A Planned Unit Development was approved with the site design and
building plan for the site to allow for decreased setbacks on the south and east property lines. The
lot split for the property was exempt from City review by State law because it resulted in industrial
parcels of over 5 acres. Therefore, setbacks to existing structures could not be addressed during the
plat. The south property line is the railroad tracks and the east property is shared with the now
Origin to Destination, LLC, a similar heavy industrial use. Because of the two adjoining uses, staff at
the time did not find there would be any adverse impact in reducing the south and east setbacks to
75 feet for all structures under 250 feet tall.
The proposed additions as well as a future building to the east were planned for future development
as part of the final site and building plan that was approved by City Council. The reason for the need
for an additional site plan and building design review for the two additions is because they exceed
thirty (30) percent of the floor area of the existing building.
ISSUE
Site Layout
The site design that was approved back in 2011 had the site configured into three sections. The most
western portion is the location of the existing 63,019 square foot building on site. The building has a
truck dock on the south side of the building and an indoor truck loading bay to the east. The access
road was designed for one-way traffic with trucks traveling east between the building and the
railroad tracks, to the north along the east side of the building, and to the west between the building
and MN Highway 55.
The center section of the site was approved to be the tank farm with the installation of twenty-one
(21) 12 diameter tanks 37 feet tall, and the relocation of an existing 42-foot diameter by 34-foot-tall
tank. The tanks are supplied by overhead pipe form the rail line and then serve the building through
over had pipes into the truck loading bay. The tank farm was designed for expansion to serve a
future second building in the eastern third of the property. Two buildings that were located in the
most western part of the site were torn down in 2022.
One addition is proposed to be located on the north side of the existing building on site and the
second addition is proposed to be located on the western portion of the building. The proposed
2
additions are located within an existing drainage area and extending across a drive isle. The applicant
plans on removing existing bituminous pavement and concrete pavement just north of the existing
building for one of the proposed additions.
Building Design and Materials
The north addition is an 85-foot deep by 270-foot wide section that is 35 feet tall and will house
additional warehousing space. The western addition is a 200-foot deep by 119-foot wide section that
is 35 feet tall and will also house additional warehousing space. The western addition will also
contain four (4) indoor truck loading bays located in the most southern portion of the addition.
Currently there are 5 indoor truck loading bays directly to the east of this proposed addition.
Facing north along Highway 55, the northern addition to the existing building will be constructed of
prefinished metal cap flashing and will contain 13 small windows throughout the addition. This
addition will have a similar look to the existing building. The western addition to the existing
building, where the truck loading bays are located, consist of concrete double tee wall panels and
exposed aggregate tan precast concrete wall panels with 4-foot high smooth white accent stripe and
will also contain 12 additional small windows. This addition will also blend in with the existing
building façade.
Landscaping and Tree Preservation
This property prior to Hawkins obtaining it was generally devoid of any trees or landscaping aside
from some trees within the MN Highway 55 right-of-way and near the previous CNR office building
onsite. In 2011, when the planned unit development final site and building plan were approved,
Hawkins submitted a landscape plan for the site. None of the then existing vegetation was proposed
to be removed. Additional landscaping was required for the site dependent on the total development
area. At the time of the original approval Hawkins proposed a development area of 650 feet wide by
650 feet deep, resulting in a development area of 422,500 square feet which included the area for the
two proposed additions.
The City Code requires one (1) tree per 3,000 feet of development and one (1) foundation plant per
linear feet of building perimeter. The City allows industrial buildings to replace four (4) foundation
plants with one (1) tree resulting in 28 trees in place of the 113 foundation plants for a total
requirement of 169 trees. The City Code requires that trees are a minimum of 2 caliper inches in size
and count every two feet in height of a conifer as one caliper inch of a deciduous tree. Based on
those standards, Hawkins was responsible with the original approval for 338 caliper inches of trees.
The updated landscape plan showed eighty-five (85) eight (8) foot tall white pine trees screening the
tank, which is equivalent to 340 caliper inches of trees. The trees that are now planted on site are
predominately on the north and west portions of the property where they provide screening for the
existing manufacturing and warehouse building and as well as the tank farm. Staff was supportive of
the landscape plan that was approved in 2011.
Access and Parking
Access to the site is from the existing parking lot and northern access to Highway 52 frontage road.
The interior access road is asphalt pavement with a flat concrete curb. The City Code requires a curb
to prevent asphalt from breaking off if an errant truck drives off the access aisle so for that reason
Hawkins agreed back during the initial approval of the site to provide a barrier (B612) curb at all
curves greater than 45 degrees, at the loading docks, and at the rail storage.
Hawkins proposed to provide eleven (11) parking stalls for the existing building on site along with
3
nineteen (19) “proof of parking” stalls associated with the interior access road, and forty-one (41)
parking stalls within the existing parking lot by the old CNR office building. This parking plan
fulfilled the forty-nine (49) required parking stalls that was required for the existing building on site
at the time, but with the additional 47,000 square foot additions additional parking is required. The
two additions will be used for warehousing which for that building use the parking stall requirement
is 1 stall per 2,000 square feet. That totals twenty-four (24) additional parking stalls needed. Hawkins
had provided a total of seventy-one (71) parking stalls with both actual parking stalls and proof of
parking which totaled out to be twenty-two (22) stalls over the amount required. This means that the
site would be two (2) parking stall short of the requirement. Staff will work with the applicant to
address this shortfall.
Utilities
In 2011, when the original Planned Unit Development final site and building plan was approved
Hawkins proposed to hook onto the existing twelve-inch water line along the frontage road and MN
Highway 55 and into the sanitary sewer line along US Highway 52. It was recommended that
Hawkins work with the City Engineer to ensure that the sanitary sewer line could be extended to the
east to serve Feed Products as well. They proposed originally that the stormwater system would
employ ponds, swales, and infiltration basins that would be fed via overland sheet flow. A condition
was required that the applicant provide modeling to ensure the system would be compliant and
would revise any plans accordingly.
With the proposed additions no sanitary sewer or water service improvements are identified for the
project. Relocated storm sewer adjacent to the westerly building addition and roof drainage pipes
from each addition are proposed to be constructed. These systems connect to existing private storm
sewer or discharge to the existing pond on site. Comments included in both the City Engineering
Memorandum and the Surface Water Management Plan Review shall be incorporated into the
project design.
CONCLUSION AND RECOMMENDATION
Staff recommends approval of the site plan and building design review for Hawkins, Inc., to allow for
the construction of two additions totaling 47,000 square feet onto the existing manufacturing and
warehouse building on its property at 13005 Courthouse Blvd in eastern Rosemount. This
recommendation is based on the plan submitted by the applicant, the findings made in this report, and
the conditions outlined in the recommended actions section above.

LEGEND
1.Owner and Contractor shall obtain MPCA-NPDES permit. Contractor shall be responsible for all fees pertaining to this
permit. The SWPPP shall be kept onsite at all times.
2.Install temporary erosion control measures (inlet protection, silt fence, and rock construction entrances) prior to beginning
any excavation or demolition work at the site.
3.Erosion control measures shown on the erosion control plan are the absolute minimum. The contractor shall install
temporary earth dikes, sediment traps or basins, additional siltation fencing, and/or disk the soil parallel to the contours
as deemed necessary to further control erosion. All changes shall be recorded in the SWPPP.
4.All construction site entrances shall be surfaced with crushed rock across the entire width of the entrance and from the
entrance to a point 50' into the construction zone.
5.The toe of the silt fence shall be trenched in a minimum of 6”. The trench backfill shall be compacted with a vibratory
plate compactor.
6.All grading operations shall be conducted in a manner to minimize the potential for site erosion. Sediment control
practices must be established on all down gradient perimeters before any up gradient land disturbing activities begin.
7.All exposed soil areas must be stabilized as soon as possible to limit soil erosion but in no case later than 14 days after
the construction activity in that portion of the site has temporarily or permanently ceased. Temporary stockpiles without
significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand
stockpiles) and the constructed base components of roads, parking lots and similar surfaces are exempt from this
requirement.
8.The normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion
of the construction site, or diverts water around the site, must be stabilized within 200 lineal feet from the property edge,
or from the point of discharge into any surface water. Stabilization of the last 200 lineal feet must be completed within 24
hours after connecting to a surface water. Stabilization of the remaining portions of any temporary or permanent ditches
or swales must be complete within 14 days after connecting to a surface water and construction in that portion of the
ditch has temporarily or permanently ceased.
9.Pipe outlets must be provided with energy dissipation within 24 hours of connection to surface water.
10.All riprap shall be installed with a filter material or soil separation fabric and comply with the Minnesota Department of
Transportation Standard Specifications.
11.All storm sewers discharging into wetlands or water bodies shall outlet at or below the normal water level of the
respective wetland or water body at an elevation where the downstream slope is 1 percent or flatter. The normal water
level shall be the invert elevation of the outlet of the wetland or water body.
12.All storm sewer catch basins not needed for site drainage during construction shall be covered to prevent runoff from
entering the storm sewer system. Catch basins necessary for site drainage during construction shall be provided with
inlet protection.
13.In areas where concentrated flows occur (such as swales and areas in front of storm catch basins and intakes) the
erosion control facilities shall be backed by stabilization structure to protect those facilities from the concentrated flows.
14.Inspect the construction site once every seven days during active construction and within 24 hours after a rainfall event
greater than 0.5 inches in 24 hours. All inspections shall be recorded in the SWPPP.
15.All silt fences must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches 1/3
of the height of the fence. These repairs must be made within 24 hours of discovery, or as soon as field conditions allow
access. All repairs shall be recorded in the SWPPP.
16.If sediment escapes the construction site, off-site accumulations of sediment must be removed in a manner and at a
frequency sufficient to minimize off-site impacts.
17.All soils tracked onto pavement shall be removed daily.
18.All infiltration areas must be inspected to ensure that no sediment from ongoing construction activity is reaching the
infiltration area and these areas are protected from compaction due to construction equipment driving across the
infiltration area.
19.Temporary soil stockpiles must have silt fence or other effective sediment controls, and cannot be placed in surface
waters, including stormwater conveyances such as curb and gutter systems, or conduits and ditches unless there is a
bypass in place for the stormwater.
20.Collected sediment, asphalt and concrete millings, floating debris, paper, plastic, fabric, construction and demolition
debris and other wastes must be disposed of properly and must comply with MPCA disposal requirements.
21.Oil, gasoline, paint and any hazardous substances must be properly stored, including secondary containment, to prevent
spills, leaks or other discharge. Restricted access to storage areas must be provided to prevent vandalism. Storage and
disposal of hazardous waste must be in compliance with MPCA regulations.
22.External washing of trucks and other construction vehicles must be limited to a defined area of the site. Runoff must be
contained and waste properly disposed of. No engine degreasing is allowed onsite.
23.All liquid and solid wastes generated by concrete washout operations must be contained in a leak-proof containment
facility or impermeable liner. A compacted clay liner that does not allow washout liquids to enter ground water is
considered an impermeable liner. The liquid and solid wastes must not contact the ground, and there must not be runoff
from the concrete washout operations or areas. Liquid and solid wastes must be disposed of properly and in compliance
with MPCA regulations. A sign must be installed adjacent to each washout facility to inform concrete equipment
operators to utilize the proper facilities.

24.Upon completion of the project and stabilization of all graded areas, all temporary
erosion control facilities (silt fences, hay bales, etc.) shall be removed from the
site.
25.All permanent sedimentation basins must be restored to their design condition
immediately following stabilization of the site.
26.Contractor shall submit Notice of Termination for MPCA-NPDES permit within 30
days after Final Stabilization.

Date: October 12, 2022
Re: Hawkins Addition – (Hawkins, Inc.)
Site Plan Review
WSB File Number 021076-000
SUBMITTAL:
Hawkins, Inc. has submitted a site plan for two building additions to their existing facilities at
13005 Courthouse Boulevard. The plans submitted were prepared by Larson Engineering, Inc.
West Des Moines, IA. Review comments were generated from the submittal not dated, received
on 09.29.2022. The submittal included the following:
▪ Paving Plan
▪ Grading & Erosion Control Plan
▪ Utility Plan
EXISTING CONDITIONS
The Hawkins site is located just south of, and between, the State Highway 52 and Highway 55
split. The parent parcel consists of land developed for industrial use with multiple buildings and
railroad spurs located on the lot. The parcel is 27.86 acres in size.
SITE PLAN
The site plan identifies two building additions one on the north side of the existing building and
one on the west side. The additions were originally identified with the development of the current
structure. The additions are located within an existing drainage area and extending across a
drive isle. The proposed site improvements primarily provide for storm water management for the
site.
GRADING AND DRAINAGE
The proposed grading consists of site grading adjacent to the additions, shaping of a shallow
swale adjacent to the westerly addition and the construction of a NURP basin near the easterly
property boundary. The constructed pond appears to overtop to the south. A defined drainage
pattern is not indicated on the plans.
SANITARY SEWER AND WATERMAIN – UTILITY PLAN
No sanitary sewer or water service improvements are identified in the project.

STORM SEWER
Relocated storm sewer adjacent to the westerly building addition and roof drainage pipes from
each addition are proposed to be constructed. These systems connect to existing private s torm
sewer or discharge to the existing pond.
SURFACE WATER MANAGEMENT
The proposed Surface Water Management plan for the site is under reviewed. Comments
included in the Surface Water Management plan review shall be incorporated in the project
design.
GENERAL
Infrastructure design shall be completed in accordance with the City of Rosemount’s Engineering
Guidelines and Standards. Infrastructure construction shall be completed in accordance with the
latest edition of the City’s General Specifications and Standard Detail Plates for Street and Utility
Construction.

Memorandum
To: Jane Byron, City of Rosemount
From: Bill Alms, PE
Henry Meeker, EIT
Date: October 17, 2022
Re: Hawkins Site Improvements Stormwater Review
WSB Project No. 021076-000
I have reviewed the documents provided by Larson Engineering on October 6, 2022. Documents
reviewed include:
• Building Plan Set dated 10/6/2022
• HydroCAD Report dated 10/6/2022
• Proposed Drainage Map dated 10/5/2022
• SWPPP dated 10/5/2022
• Geotechnical Report dated 9/23/2022
• Comment Response Letter Dated 10/6/2022
Applicant should provide responses to each comment. Comments from the 10/6/2022 letter are in
red and updated review comments are in blue. I offer the following comments below.
Grading, Drainage, and Erosion Control Comments:
1. General
a. A SWPPP will be required before construction can begin.
A draft SWPPP has been provided for review.
The provided SWPPP appears to be sufficient.
b. An NPDES permit will be required before construction can begin, unless a
previous NPDES permit exists and is still valid.
A new NPDES permit will be needed and will be obtained by Knutson
Construction prior to work beginning on the project.
NPDES permit has been provided.
c. An operations and maintenance agreement for stormwater facilities is needed.
An O&M agreement will be drafted by the Owner and reviewed and approved by
the City.
Noted, provide when drafted.
d. A geotechnical report with infiltration rate testing is recommended.
A Report of Geotechnical Explorations prepared by AET and dated September
23, 2022 and a Report of Geotechnical Exploration and Review prepared by AET
and dated July 26, 2011 have been provided for review. While infiltration testing
was not performed as part of the exploration and testing work, the boring logs
included clearly shown sandy soils are found throughout the site and are very
Jane Byron
10/17/2022
Page 2
K:\021076-000\Admin\Docs\Stormwater Review\Hawkins Stormwater Review Memo 10-17-22.docx
capable to drawdown the existing infiltration basins on -site. This is also evident
in the history of pond performance over the past 11 years.
Noted, based on geotechnical results it appears the existing soils provide the
necessary infiltration capacity.
e. If the site is permitted under an industrial stormwater permit, provide the spill
emergency response plan.
The site is permitted under an industrial stormwater permit and the spill
emergency response plan will be shared.
Provide spill emergency response plan.
f. Provide phasing plan or further clarification of proposed improvements. Based on
provided materials and communications, it is unclear what site improvements
have already happened, are proposed with this permit application, or are
proposed further in the future.
A Phasing Plan has not been provided since all proposed work now clearly
shown on the Civil Plan Sheets prepared for the Site Plan Application will be
completed prior to July 2, 2023. The west warehouse addition is planned for
completion just weeks before the north proposed addition. Site restoration will
occur last with final stabilization planned for July 2023.
Noted.
2. Ponds and Wetlands
a. No comments.
3. Emergency Overflow Routes:
a. All emergency overflow locations and elevations must be shown for site low
points and stormwater basins.
EOF locations and elevations have been shown on the Plans.
Noted.
4. Retaining Walls:
a. No comments.
5. Erosion Control:
a. Proposed infiltration basins must have silt fence around the perimeter until site
stabilization has been achieved to prevent loss of infiltration capacity.
Silt fence has been shown where needed on the Erosion Control Plan. No
infiltration basins have been proposed, although the existing basins have been
protected with silt fence.
Noted, silt fence as shown is sufficient.
b. Silt fence is required to capture runoff wherever site construction has positive
drainage leaving grading limits. For example, silt fence is needed for the
perimeter of the berm on the north side of the site.
Silt fence has been shown where needed on the Erosion Control Plan. Site
disturbances will only occur within the loop road around the proposed additions
and at the proposed sedimentation basin on the east side of the site.
Noted.
c. Specify final stabilization seeding on plans.
Proposed seeding work has been shown on the Erosion Control Plan.
Jane Byron
10/17/2022
Page 3
K:\021076-000\Admin\Docs\Stormwater Review\Hawkins Stormwater Review Memo 10-17-22.docx
Proposed seeding work does not appear to be shown aside from note on sheets
C3.1 and C3.2.
6. Grading:
a. Show NWL and HWL for all basins on grading plan sheet, only some
sedimentation basins have these shown.
The NWL and HWL have been updated on the Grading Plan and in the
HydroCAD to reflect the as-built conditions and the proposed for the new
sedimentation basin.
Noted.
Stormwater Management Plan:
1. General Storm Sewer Design
a. The minimum allowable storm sewer size is 15” according to City engineering
guidelines.
Even though a 15” pipe size is well oversized for many of the small sub-
catchments proposed, 15” minimum pipe sizes have been provided downstream
of catch basins.
Noted.
b. Catchbasins in unpaved areas are not typically allowable. City staff to approve or
deny this variance.
A catch basin in the depressed green space south of the west addition is
proposed. This catch basin is needed to prevent meltwater from snow removal
operations from running over the loop road which acts as the primary vehicular
entrance to the site.
Noted, this catchbasin is allowable based on needs provided.
c. A 3’ sump is required on structures immediately upstream of basin inlets.
A 3’ sump has been provided for all proposed catch basins placed upstream of a
basin inlet.
Noted.
d. Confirm no conflicts at storm sewer crossings with other utilities. Provide
insulation if storm sewer crosses within 2’ of watermain or sanitary sewer.
No utility crossings are being proposed.
Noted.
e. Pond 13P is modeled with a 6” vertical orifice but is shown with an 18” FES
outlet. Reconcile difference between model and plans.
f. Pond 14P is modeled with a starting elevation of 902, but the OCS modeled
begins at an elevation of 904.1.
2. Water Quantity
a. Provide modeling of storm sewer facilities with updated Atlas 14 precipitation for
the 2-, 10-, and 100-year 24-hour events. Modeling of the 100-year 10-day
snowmelt event is needed as well.
A HydroCAD model has been provided for both the storms mentioned below as
well as the 100-year, 10-day snowmelt event.
The provided HydroCAD report does not include the 2-year 2.8”, 100-year 7.41”
or 10-day 7.2” events.
Jane Byron
10/17/2022
Page 4
K:\021076-000\Admin\Docs\Stormwater Review\Hawkins Stormwater Review Memo 10-17-22.docx
b. Longer timespans are recommended for HydroCAD modeling to fully capture
peak flows, especially when modeling the 10-day event.
3. Rate/Volume Control
a. Include any offsite drainage in modeling. For example, the drainage map
suggests offsite area to the north is considered as tributary area, but this 24S
subcatchment is not present in the modeling.
The HydroCAD model and Drainage Map have been updated to include site area
tributary to the basins and those that bypass treatment to the south.
Noted.
b. Gravel roads should be counted as impervious with a curve number of 98 in
hydrology modeling.
The HydroCAD model has been updated to show accurate subcatchments with
existing gravel surfaces modeled with a curve number of 98.
Subcatchments 28S and 37S still show gravel surface with the CN of 85.
c. Outlet control structures with skimmers are required for basins with offsite flows.
No basins are proposed for offsite flows.
Noted, outlet control structures are not needed as the site proposes to use the
excess infiltration capacity in the downstream regional BMP.
4. Freeboard
a. The modeled 100-year HWL for basin 9P is 913.07, above the proposed FFE of
913 for the eastern building. The City requires 3’ of freeboard from HWL or 2’ of
freeboard and meeting the following requirements:
• Provide flood storage volume within the freeboard area that is at least 50% of
the flood storage volume below the 100-yr HWL; and
• 25% outlet obstruction does not increase the 100-yr HWL by more than 1’;
and
• Adequate EOF from basin to provide assurance that 1’ freeboard will be
maintained for proposed low opening
The existing building and proposed additions will have a FFE of 917.00. A
minimum of 3’ of freeboard will be provided.
The proposed sedimentation basin north of the building expansion has a HWL of
914.45, within 3’ of the building FFE of 917.0.
5. Water Quality
a. The City requires infiltration capacity such that 1/12 of an acre-foot/acre/day is
achieved for the entire site’s acreage. Based on a site area of 28.03 acres, this
infiltration area is 1.46 acres. The proposed infiltration area is 0.82 acres,
meaning there is an infiltration area deficit of 0.64 acres.
i. This deficit can be accounted for with excess infiltration capacity in the
downstream regional basin constructed with the ATS site improvements.
In reviewing the Stormwater Summary for the ATS Site Improvements excess
volume is available for the Hawkins’ site runoff volume.
Noted.
b. While NURP dead pool storage is provided onsite, the required NURP dead
storage of runoff from a 2.5” storm over the tributary drainage area must be
calculated for each basin to ensure design standards are met.
A HydroCAD model for the 2.5” event has been provided to show the
sedimentation basins were designed with the proper dead pool storage.
Jane Byron
10/17/2022
Page 5
K:\021076-000\Admin\Docs\Stormwater Review\Hawkins Stormwater Review Memo 10-17-22.docx
Noted, provided dead storage meets this requirement.
6. Easements
a. Easements will be needed over all proposed stormwater basins.
Easements will be provided.
Noted.
