9.c Engineering Updates 1-19-21 City of Scandia Engineering Updates 1/19/2020 Engineering italics = old information · 2021 Street Improvement Project & Layton Ave  City Council authorized Plans and Specifications for the 2021 Street Improvement Project at the October 20th City Council Meeting.  As a separate agenda item, will have information prepared to Approve Plans & Specifications and Authorize Ad for Bid on the January 19th City Council meeting. · Anticipated Bid Opening – February 17, 2021 · 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: https://www.clflwd.org/documents/Agendaitem10b-1-MemoWMPUpdate_000.pdf. · January 7, 2021 – completed Technical Advisory Committee meeting · January 12, 2021 – completed Citizen Advisory Committee meeting · January 14, 2021 – completed regular Board meeting · January 19, 2021 – Board workshop: detailed discussion of draft WMP · January 28, 2021 – regular Board meeting · February 11, 2021 – regular Board meeting · TBD/if needed in Feb – Additional Workshops for further detailed discussion · February 25, 2021 – Regular Board meeting, proposed deadline to approve the 60- day draft · Late February/early March 2021 – Begin 60-day agency and public comment period · CLFLWD & Scandia Staff Quarterly Meetings  Meeting on October 19, 2020 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 – Draft Capital Improvement Plan (CIP) 2020 – 2024  Washington County will hold a public hearing on December 15, 2020, prior to adopting the final document.  CSAH 3 (Olinda Trail) update provided at meeting · 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.  Project Manager, Emily Jorgensen, 651-430-4338 · emily.jorgensen@co.washington.mn.us · 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.
