· Bliss Drainfield System
Both the 2020 permit application for this system and the “final report” for nitrogen mitigation have
been completed and submitted to the MPCA. The memo which serves as a final report doesn’t
present final solutions for the nitrogen issue, but instead outlines the issues that have been found
and solved in this treatment system, as well as some additional testing that will now be
recommended to get a handle on the nitrogen, BOD, and TSS entering and leaving the facility. The
hope is to gain us a little more time from the MPCA before they mandate action. We’ll use this time
to perform the aforementioned testing and evaluate options for removing nitrogen at Bliss.
To date we still have not heard anything from the MPCA regarding the permit and this is very typical.
This means the City’s existing permit is still in effect until the new permit is issued.
· Sump Pump Inspection Program
2 homes/cabin remain to be inspected.
· Bliss Addition Stormwater Planning
Public Outreach meeting being held at City Hall with the adjacent property owners prior to the City
Council meeting, on April 16, 2019, from 5:30pm – 6:30pm.
Met with watershed district on 8/2 to discuss preliminary options for expanding regional water
storage, restoring infiltration capacity and improve water quality. The watershed made some great
recommendations for managing overall project costs and those options are currently being explored.
Second public meeting occurred on August 20th. Preliminary stormwater management practices
were presented to the residents and were well received. Some new recommendations were also
presented and considered in the plan revisions.
Final Draft will be presented to the City Council at the November 19, 2019 meeting.
Meeting with City Staff and Watershed District was held on January 16, 2020 to discuss prioritization
and implementation schedule for the items presented in the final stormwater study. Separate costs
estimates have been put together based on the prioritization which will be used for future funding
submittals.
Recent engagement with the Carnelian Marine St. Croix Watershed District resulted in the two bullet
points below:
· Cost responsibility - Who would take on what costs and how? Ideally the District would like
to participate with a Clean Water Fund Grant.
· Timeline - The District is working to complete the Subwatershed analysis for Big Marine
Lake. It will be complete by June 2021. Clean Water Fund Grants are awarded based on
how the score. Without a completed Subwatershed analysis for the entire lake and
application would score low. We planned to apply for a CWF grant in the fall of 2021 (after
the completion of the analysis). If the City would like to dedicate funding and move up the
timeline, they could request the CMSCWD Board of Managers consider funding a phase of
the project without a CWF grant. I do know that next year’s budget is tight with the state
required 10-year management plan update.
Temporary drainage improvements that included two options were presented at the August 5th City
Council Workshop that were intended to relieve drainage concerns at the property of 19123 Layton
Ave. Upon the discussion there seems to be separate opinions forming on both sides of the street of
what temporary solutions are favored but why the ultimate correction is not just completed in
conjunction with the storm sewer improvements identified in the neighborhood stormwater study.
On October 14, 2020 at the Watershed Board meeting, Board Managers approved $3,600 cost share
for option 1.
Watershed anticipates in 2021 they will apply for 2022-2025 Clean Water Funds to implement stage
1 and 2, but could potentially also apply for all three stages. It should also be noted it will be difficult
for the District to participate in just the directional pipe installation without the water quality BMPs
being installed in that area. City may want to consider adding water quality practices to this stage to
leverage more funds from District (with or without Clean Water Funds).
· Stage 1 – directional drilled pipe to re-route drainage to wetland
· Stage 2 – North Layton Ave bioinfiltration basin, concrete trench and enhanced ditch
improvements, west bioinfilration basins, and 189th culvert crossings and enhanced ditches.
Watershed has completed the evaluation of potential projects on Big Marine. The Subwatershed
Analysis is currently being prepared. Schedule still anticipates to be on track to apply for Clean Water
Funds in July 2021.
· CLFLWD Comprehensive Watershed Management Plan
Watershed District staff reviewed the following topics with the City staff though a Zoom Meeting on
May 12, 2020. Some of the topics included; Lakes (pollutants, recreational use, shoreline), Aquatic
invasive species, Stormwater management (Low Impact Development, rules), Floodplain (flood
resiliency), Resiliency planning (climate adaptation, development demands), Groundwater (quantity
and quality)
The Water Management Plan timeline: Watershed has pushed back the expected start date of the
60-day review. Instead of January, it’s looking more like February or March. Here’s a brief table of
upcoming checkpoints. For a more extended outlook, see the memo here:

· CLFLWD & Scandia Staff Quarterly Meetings
Meeting held on October 19, 2020.
Meeting on February 9, 2021 covered the following topics:
· MnDOT – Hwy 97 & Oakhill/CR 52
First initial contact/conference meeting with MnDOT to discuss issues and concerns with intersection
safety on October 13, 2020.
· Signing – MnDOT will upgrade the size of all the fluorescent yellow-green signs and add
fluorescent yellow green tape to the sign structure (the post). At the crossing itself MnDOT
will be placing the enlarged signs back to back as to warn motorist on approach of the
crossing on Hwy 97. These additions will enhance the visibility of the intersection.
· Striping - The school Xing pavement markings were completed with the last pavement
maintenance project, if City staff observes that these are worn out, please send in a request
to MnDOT and they will submit it to our pavement makings crew.
· Washington County’s first Bicycle and Pedestrian Plan
TAC Meeting #3 was held virtually on March 25, 2020. The planning consultant used this time to
present draft materials, which included a revised Future Network map and a methodology for
prioritizing future projects.
Washington County is launching their last phase of the public engagement. The website up to date
with the final draft plan, videos summarizing each chapter and a questionnaire for folks to provide
feedback.
There will be a workshop on the final draft of the MOVE Washington County Bicycle and Pedestrian
Plan with the Washington County Board of Commissioners on Tuesday, February 2, 2021 and plan
adoption is scheduled February 9, 2021.

· Floodplain Risk Assessment
Online Workshop held, January 5, 2021
The Brown’s Creek Watershed District (BCWD), Carnelian-Marine-St. Croix Watershed District
(CMSCWD) and the Comfort Lake – Forest Lake Watershed District (CLFLWD) are jointly evaluating
approaches to conducting a floodplain mapping/flood risk assessment with two goals in mind:
· The short-term goal is to outline potential approaches the watershed districts could take to
map and quantify future flood risk.
· The long-term goal for these watershed districts is to build a common understanding of risk
and prioritize projects and other resiliency actions.
Small group met on February 3, 2021 to discuss the outcomes of the online workshop and
next steps. A summary is anticipated to follow soon.
