CITY OF OAK PARK HEIGHTS – WEEKLY NOTES for: January 20th, 2023
TO: City Council Members& Staff
FROM: Eric Johnson, City Administrator
Zoning & Development Items:
1.No new applications have been received for the February Planning
Commission.
2.Staff does have a planned meeting next week with a possible end-
user / developer for the former A1 site – along STAGECOACH.
We have not yet heard of specifics, but we have advised the
possible purchaser that the site is zoned Business / Transitional.
3.The Planning Commission has a vacancy and Staff has initiated
the recruitment notice. If you know anyone who wouldlike to
serve, please ask them to reach out to myself of Julie Hultman for
an application packet.
4.Staff has been communicating with the KOHLS site manager
about the sign hanging on their north face, that is poor condition
and was not permitted initially. It was removed on 1/15/23
however – Staff does need to chase these from time to time as the
on-site managers often appear indifferent to these type of situation.
5.Bremer Bank has been asked to clean the side of their building; and install black/screening in their lit sign. The
Starbucks developer has taken care of this for them.
Other Items:
The City has received a responsefrom the Valley Branch Watershed District related to its comments on their proposed
rule changes. These are enclosed and we will communicate with the City Engineer for any necessary follow-up.
The CIty has completed the 2023 Washington County Hazardous Waste Generation Report and Application for 2023. We
are awaiting our final License. The fee was $106.00.
Mayor McComber Provided:
1.NLC Update for 1/16/23 and 1/18/23
2.Information on possible legislationrelated to REMOTE MEETINGS – when illness may prevent attendance –
not under State of Emergency - see www.house.leg.state.mn.us/SessionDaily/Story/17535

Re: Valley Branch Watershed District Rules
Dear Mr. Johnson:
Thank you for your September 7, 2022, comments on the draft Valley Branch Watershed District
(VBWD) rules. I received your comments on October 26, 2022.
Oak Park Heights’ land within the VBWD includes Stillwater Area High School, the Oak Park
Ponds/Kowalski’s shopping area, and the businesses south of TH 36 and east of Stillwater
Boulevard. All parcels appear to be developed.
Attached is a table of comments received by the August 15, 2022, deadline for comments and
responses to those comments. Below are your comments and VBWD responses.
1.Page 22 - Rule 2 – Policies – Item 9. – Requires land used for stormwater management facilities be
preserved by dedication and/or perpetual easement to the VBWD. Since VBWD is a MS4 permittee,
we understand they are required to have a legal mechanism that allows them to conduct inspections of
privately owned BMP’s. The easement seems to go beyond the terms of the permit.
VBWD requires easements over areas used for stormwater management so that stormwater
management continues into perpetuity. This has been a VBWD policy for decades. In
practice, VBWD has not required easements over stormwater management practices of
projects implemented by MS4 (Municipal Separate Storm Sewer System) operators. From
the draft rules out for review last summer, the policy was revised to reflect this practice.
Submittal requirement K in Rule 1 and Standard 10.A of Rule 2 were also revised.
In addition, VBWD has a Memorandum of Understanding with one VBWD community
regarding easements within private developments. If the City of Oak Park Heights would like
to discuss this option, please contact me.
2.Page 23 - Rule 2 – Standards – Item 6.A –
acre of impervious needing to treat 1.3 inches times the impervious surface. This is 18% more than
increase in treatment volume for larger sites?
For new sites that create 1 acre or more of impervious surface and disturb 10 acres or more
of land, the required volume control standard is 1.3 inches times the new impervious

surface area. If a soil management plan is provided so that at least 50% of the remaining
pervious area disturbed by the project will be restored, the volume control standard
remains at 1.1 inches times the new impervious surface area. The additional 0.2 inch of
required volume control is based on an analysis of compacted soils summarized in Barr
Engineering Co.’s report to the MPCA, Assessment of MIDS Performance Goal Alternatives:
Runoff Volumes, Runoff Rates, and Pollutant Removal Efficiencies, June 30, 2011.
3. Page 25 - Rule 2 – Standards – Item 6.D.i. – States that a project must provide the required volume
control onsite through a different mechanism than infiltration. Since the city does not allow
infiltration within the DWSMA, filtration is the primary means of water quality treatment. Does
VBWD consider filtration a volume control mechanism? Or will property owners be required to try
other volume control practices prior to filtration (e.g. stormwater reuse via irrigation)? OPH will not
permit filtration in its DWSMA and will not be permitted to be violated by VBWD rules or
policies.
Filtration provides little, if any, stormwater volume control. VBWD requires stormwater
volume control. If in filtration is infeasible, the permit applicant needs to explore other
stormwater volume control mechanisms (e.g., capture and use for irrigation). Permit
applicants must conform to the city’s rules and the VBWD’s rules.
4. Page 32 - Rule 2 – Standards – Item 17 – States that projects creating a total of 1 acre or more of new
or fully reconstructed impervious surface that the permit holder must provide a chloride management
plan. Does this apply to city road reconstruction projects? PLEASE LET US KNOW.
Chloride management plans will be required with city road reconstruction projects.
However, MS4 operators with Winter Road Materials (salt) Management Plans will be
exempt from this requirement.
5. One thing to note related to MS4 rules – since both VBWD and OPH are MS4 permittees, they will
both be required to have maintenance agreements with property owners. This seems very redundant.
Noted.
The VBWD Board will be holding a public hearing regarding the rules at 8 p.m. on January 26, 2023,
at Baytown Community Hall. If the Managers adopt the rules, the City of Oak Park Heights will
receive additional information on the implementation steps.
Sincerely,
John P. Hanson
Engineer for the Valley Branch Watershed District
