SUMMARY
Property Owner: Warren and Kathleen Israelson
Applicant: KJ Walk, Inc
Site Location: Northeast quadrant of the intersection of Highway 3 and County
Road 46 and the northeast quadrant of the intersection of Business
Parkway and County Road 46 Parkway and County Road 46.
Site Area in Acres:
Comp. Guide Plan Designation: CC – Community Commercial
Current Zoning: C4 – General Commercial & C3 – Highway Service Commercial
The City Council is being asked to consider a request by KJ Walk, Inc for preliminary and final plat
approval for Rosewood Commons Second Addition in anticipation of future commercial development at
two sites located west of the intersection of Business Parkway and CSAH 42 and one site located east of
the intersection of Business Parkway and CSAH 42. Commercial development projects require site plan
review, so if the preliminary and final plats for Rosewood Commons 2nd Addition are approved site plan
reviews will be required for each site when. A minor amendment to the Rosewood Commons Planned
2
Unit Development Agreement is required with the approval of the preliminary and finals plats. Lots 1 and
2, Block 1 do not meet the minimum lot width requirements for the C4 – General Commercial zoning
district so an amendment to the Rosewood Commons PUD is needed to allow for the two lots to be
approved as is. Approval of a minor amendment to the Rosewood Commons PUD will be included as
condition of approval with the plats. Staff is recommending approval of the preliminary and final plats and
approval of the minor amendment to the Rosewood Commons PUD.
PLANNING COMMISSION ACTION
The Planning Commission held a public hearing to review the request and receive public comment. The
Commission noted that the proposed landscaping plan will need to be revised when site plan reviews
come forward for the proposed lots. The Commission questioned if there was a site plan provided for Lot
1, Block 2. Staff confirmed that a preliminary site plan for the lot was not provided and informed the
Commission that they will review further detailed plans for the site once a site plan review application is
applied for. No public comments were received during the hearing. The Commission voted unanimously
to recommend approval of the preliminary and final plat requests.
BACKGROUND
The Planning Commission reviewed and recommend approval of the Rosewood Commons Planned Unit,
Preliminary Plat, and Site Plan for the first phase of development at its meeting in September 2020. The
site was originally approved for a mixture of High Density Residential and Commercial Use which could
include senior housing, a hotel, various retail, and a memory care facility. The proposed memory care and
assisted living facility was approved by the City Council in June 2022 and is located within the Rosewood
Commons Plat.
The Rosewood Commons final plat was approved by the City Council in April 2022. This final plat was
the final step in the subdivision process and was necessary to allow for construction to being on the six
apartment buildings that received final site and building plan approval in 2020. With the submittal of that
final plat the applicant did include two additional parcels in the southern portion of the preliminary plat
area for future commercial use, but because the parcels were not included in the original preliminary plat,
they were not able to be platted with Rosewood Commons. The Planning Commission is required to hold
a public hearing to review commercial parcels as part of the preliminary and final plat process so that is
why the applicant was required to go through the preliminary and final plat process for the proposed
commercial lots that are being proposed.
ISSUE ANALYSIS
Legal Authority Legal Authority. Preliminary and final plat requests are quasi-judicial decisions for the
Planning Commission. This means the Planning Commission is acting as a judge to determine if the
regulations within the Comprehensive Plan, Zoning Ordinance, and Subdivision Ordinance are being
followed. Generally, if the proposed preliminary and final plats meet the standards and requirements for
reviewing this type of request it must be approved.
Plat
The applicant is proposing a plat that will contain three buildable lots that were originally apart of the
Rosewood Commons Plat and the Rosewood Estates Plat. Two of the proposed lots are located in the
northwestern quadrant of CSAH 42 and Business parkway intersection and are adjacent to the south side
of the private street of 149th Street, which is constructed within Rosewood Commons. The proposed third
lot is located in the northeastern quadrant of CSAH 42 and Business Parkway intersection and is also
adjacent to the south side of 149th Street. The land located west of the proposed Lot 1 and 2, Block 1 will
be outloted on the plat as Outlot A.
The Zoning Ordinance contains standards related to the dimensions of lots within the C3 – Highway
Commercial and C4 – General Commercial zoning districts. There is no minimum lot depth specified in
3
the City Code, but a minimum lot width and area is required to be followed. The plat shows that Lots 1
and 2 of Block 1 do not meet the required 120-foot minimum lot width requirement. Lot 1, Block 1 has a
minimum lot width of 106-feet in the northern portion of the site and Lot 2, Block 1 has a minimum lot
width of 119.49-feet in the southern portion of the site. A minor amendment to the Rosewood Commons
Planned Unit Development Agreement to allow for the reduced minimum lot width is required for Lots 1
and 2, Block 2 and will be included as a condition of approval for the preliminary and final plats. The
standards and a comparison of the proposed plat is provided in the table below. Standards related to
setbacks, lot coverage, building height, etc. will be reviewed by staff and the Planning Commission when
site plan review applications are submitted.
Lot Standard Required Lot 1, Block 1 Lot 2, Block 1 Lot 1, Block 2
Minimum Width 120 feet 106 feet 119.49 feet 291 feet
Minimum Area 20,000 sq ft >20,000 sq ft >20,000 sq ft >20,000 sq ft
Engineering
The request was reviewed by the City Engineer, with comments provided in a memorandum included with
the attachments. The main access to Lots 1 and 2, Block 1 will be from a common driveway centered on
the westerly property line of Lot 1, Block 1, which also extends into Outlot A. Shared driveway easements
and maintenance agreements will be required between the two lots of Block 1 and the future lot to be
platted with the development of Outlot A. The main access to Lot 1, Block 2 comes from an existing
driveway extending from 149th Street at the northeast corner of the parcel. This driveway location will need
to be the access and egress location for the lot. Noted in the engineer’s memo is that 149th street adjacent
to Lot 1, Block 2 is located within a roadway easement as it is not on platted right of way. The platting of
149th street must include the vacating of roadway and drainage and utility easements in that area.
Sanitary sewer and water services have been extended to each of the three lots. Services were extended to
Block 1 with the development of Rosewood Commons. Services to Block 2 extend from 149th Street
midway along the lot. Also noted was tree plantings will need to allow space for access and maintenance
for future proposed infrastructure.
Park Dedication
The City’s Parks and Recreation staff reviewed the proposed plat and is recommending a fee-in-lieu of
land dedication for the proposed commercial sites. The cash dedication for the 4.77 acres of commercial
development would be $42,930 (4.77 acres x $9,000 per acre).
CONCLUSION AND RECOMMENDATION
The Planning Commission and staff are recommending approval of the preliminary and final plats based
on the information provided by the applicant and reviewed in this report, subject to the conditions listed
in the recommended action. Future site plans for projects as they come to fruition will be brought
through the formal approval process.

Applicant should provide responses to each comment. Updated comments per the 8/24/2022
submittal are shown in red. I offer the following comments below.
Grading, Drainage, and Erosion Control Comments on Plan Set
1. General
a. An NPDES permit will be required prior to the start of construction.
b. Inlets required every 300’ on streets to prevent runoff from flowing through
intersections.
c. Inlets should be located such that 3 cfs is max flow at the inlet for 10-year design
and does not exceed applicable spread design for road. Provide calculations
showing inlets 1-3, 1-4, and 3-1 meet this requirement.
While structures 1-2 and 3-1 still show rates much greater than 3 cfs, it appears
the tributary area to these will likely change with future development. No action
required
d. Street catchbasins require 3 foot sumps prior to discharging to public storm
sewer and the final structure before outletting to a water basin requires a 3 foot
sump.
e. Indicate drainage structure type and size on storm sewer profiles. Ensure
structures are constructable based on pipe sizes and angles. As designed,
structure CB 3-2 would require an 84” manhole to be constructable with the angle
between the two pipes.
f. Correct SWPPP to include proper contact for long term O&M of stormwater
facilities.
g. Provide response to comments provided by the City from previous review.

a. Show Regional Basin ID, NWL, HWL, and storage volume for all BMPs receiving
drainage from the site.
b. Show/define access routes for maintenance purposes to all manholes, inlets,
and/or outlets at ponding areas that are outside of public ROW. See Section 6,
Grading, in the City of Rosemount Engineer Guidelines for more detail on the
construction requirements of these access routes.
c. Show existing or proposed city standard regional OCS on BMPs receiving
drainage from the site.
3. Emergency Overflow Routes:
a. Show EOF routes. All EOF routes need to be encompassed by a drainage/utility
easement. Overland EOF routes shall be provided for all basins in addition to the
normal pipe outlet. Show EOF routes from all low points and show high point
elevation along EOF routes and the directional flow arrows. Show EOF route
typical section with bottom width and side slopes. If a pipe is installed to provide
an EOF, label it as EOF.
4. Retaining Walls:
a. No comments.
5. Erosion Control:
a. A separate erosion control plan sheet is required that will accompany grading
plan. See Section 5, Erosion Control, of the City of Rosemount Engineering
Guidelines for more information on requirements.
6. Grading:
a. Provide the datum used for grading elevations.
Stormwater Management Plan:
1. General Report Requirements
a. Include narrative describing existing and proposed drainage conditions for site.
b. Offsite drainage must be considered in site modeling.
Offsite drainage to Pond B can be reduced based on new storm sewer
development in the area, the area can be reduced to 12.61 acres and the extents
shown in the included drainage exhibit.
c. Include an approximate timeline for anticipated improvements to Pond C.
2. General Storm Sewer Design
a. Label all storm sewer as public or private. Storm sewer within public ROW or
trunk conveyances shall be public owned and maintained.
b. Include drainage area maps showing existing and proposed conditions.
c. Include catch basin drainage area map and pipe size calculations.
d. Modeling should show storm events as defined in the City of Rosemount’s
Engineering Guidelines, Section 2.f.:
i. 2-year
ii. 10-year
iii. 100-year
iv. 10-day snowmelt
Modeling must be consolidated, using different models to determine certain
HWLs is not allowable. HWLs must be determined with offsite drainage included ,

no exfiltration to be included in modeling. Pond B has no NURP pretreatment
volume included in the modeling.
e. Proposed drainage calculations should incorporate stormwater analysis of the
future development to the west (Outlot E) and be sized for future impervious
areas. Include analysis and narrative of these calculations in stormwater report.
f. Show building roof leader connections to storm sewer throughout entire project
site.
g. Provide insulation for storm sewer crossings within 1 8” of vertical separation to
watermain.
h. Move CB 1-3, 1-4, 3-6, 3-7, 3-10, 3-11 and 3-12 to a curb line.
i. The pipe between CB1-5 and FE 1-6 must be sized appropriately to convey the
drainage needs of the site after full development. Future development must route
to CB 1-5 instead of constructing additional outfalls into Pond B.
One additional future outfall to Pond B is acceptable.
j. Include storm sewer connecting Pond A culvert outlet, north of 2717 148th St W
parcel, to CB 1-3 and ultimately Pond B .
k. The maximum allowable velocity in storm sewer is 10 fps generally and 6 fps
prior to an outfall to a BMP. Pipes between structures 1-1 and 1-6 must have
shallower slopes to reduce this velocity. Pipe velocity into the pond currently
shows 12.2 ft/sec.
3. Water Quantity
a. See supplemental review information from 2017 modeling regarding regional
basin storage requirements. Indicate which option has been chosen or specify
other proposed storage design.
4. Rate/Volume Control
a. Include summary table for onsite and offsite runoff to each Pond in the
stormwater report in existing and proposed conditions.
b. Include existing and proposed runoff rates for all storm events.
5. Freeboard
a. Include basement floor elevations analysis (Section 2.l.i-iii.)
6. Water Quality
a. Include NURP analysis (see Section 3.a.i-viii.)
Modeling a 2.5” storm event is recommended to determine the required dead
storage volume for Pond B, this includes offsite areas.
b. Provide calculations of required and provided water quality volumes.
See above comment.
c. Show locations of basins providing water quality treatment.
7. Easements
a. Provide D&U Easement over outfalls to basins.

Subject: Rosewood Commons Second Addition Preliminary and Final Plats
The Parks and Recreation Department recently reviewed the plans for the Rosemount Commons
second addition development plans and has the following comments:
Parks Dedication
Because the City is not looking to acquire parkland in this development, thus the parks dedication
for this will be cash in-lieu of land. The cash dedication for the 4.77 acres of commercial
development would be $42,930 ($9,000 per acre x 4.77 acres = $42,930).
Please let know if you have any questions about this memo.
