09.c Engineering Updates 3-15-2022 City of Scandia Engineering Updates 3/15/2022 Engineering italics = old information · 2022 Street Improvement Project (Melanie Trail N and 238th Street N)  City Council authorized Plans and Specifications for the 2022 Street Improvement Project at the June 15th City Council Meeting.  Staff met with Scandia Public Works on November 23rd to discuss scope of the project, as well as go over any questions or concerns.  Received final Geotechnical report from AET December 2nd, 2021.  We plan to request Approval of Plans & Specifications/Authorize Ad for Bid at the January 18, 2022 Council Meeting.  Bid opening was completed on February 9, 2022 in which the City received 7 bids.  Project awarded to Asphalt Surface Technologies Corporation at 2/15/2022 City Council Meeting.  Wetland Delineation near cross culvert on south end of Melanie Trail N is scheduled to occur after snow melts.  Astech is anticipating a June start date. Preconstruction Meeting date has yet to be set, but likely will be scheduled for mid-May. · 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.  City received on February 22, 2021 a Pre-Public Notice Review of Draft Permit - Bliss Collector WWTP (#MN0054119) that also included a statement of basis outlining any changes or new requirements to the draft permit. This 30 day pre-public notice review period starts on February 22, 2021 and ends on March 24, 2021. Once your pre-public notice review is complete the draft SDS permit will be placed on public notice for 60 days. · First thing that needs to be done is complete a Facility Evaluation Report within 180 days of issuance of the new permit they requested. Based on the report, MPCA will then ask the City to follow either Track 1 or Track 2. Track one is the new monitoring well. Track two is a facility upgrade. There are a few other changes to the permit, they include some additional monitoring required over this permit. Also, MPCA is requesting flow monitoring at WS 004, WS 005 and WS 006. These are to each of the infiltration trenches. We are in the pre-public draft notice stage where just the City received these draft documents and can comment. We can review and suggest changes or modifications prior to March 24th. · Current updates: Under track 1, the requirement to abandon GW 008 is included because using this well for monitoring is problematic, since we have no information on the well’s construction nor well boring records. Based on the limited information we do have, it is the opinion of MPCA hydrologist, Steven Stark, that this well is too deep to be used as a monitoring well and may be sampling a confined aquifer. All monitoring wells should be sampling the surficial aquifer and have well screens that bisect the watertable. · The justification for proposed timeline is sufficient and the new timeline will be incorporated into the draft permit. Shown below (last page of this report) is a revised compliance schedule. Flow monitoring requirements at WS 004, WS 005, and WS 006 will become effective upon installation of the flow monitoring equipment. The permit will continue to the 60-day Public Notice period.  The final permit has been issued. The assumption is that we’ll end up on Track 2, with required system improvements due to the nitrate issue. Only thing that needs to take place in the next 6 months (February 28, 2022) is for new flow meters to be installed at the system, something we’ll begin working on. At the one year mark (September 1, 2022), we’ll need to have a Facility Evaluation Report drafted to summarize the system’s ability or inability to meet the nitrate limit. · Sump Pump Inspection Program  2 homes/cabin remain to be inspected. · Bliss Addition Stormwater Planning  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.  Meeting scheduled with City Staff and Watershed District to discuss Clean Water Fund Grant Application on Thursday, July 22nd.  The CMSCWD has been notified a CWF grant award. The application was ranked 7th of 53 projects and will be awarded for a total of $272,400 for the installation of Bliss Addition water quality practices identified in collaboration with the City of Scandia. I anticipate the grant will be fully executed by May, 2022 and will expire on December 31, 2025. The CMSCWD is planning to post an Engineering RFQ for plan development and construction administration in March. The goal is to complete construction documents in December 2022 and put the project out to bid in January 2023 with substantial completion of construction in 2023. · CLFLWD Comprehensive Watershed Management Plan  Board of Water and Soil Resources approved the Plan on August 26  CLFLWD Board adopted final Plan on September 23  CLFLWD distributed the final approved Watershed Management Plan to partners and required entities on October 21st, completing the final step in the WMP update process. The final Plan is available at https://www.clflwd.org/watershed-management-plan.php. Municipalities were informed of the requirement to revise or prepare LWMPs that conform to this Plan. Please see section 8.1.2 of the Plan for more information. Note that some of the requirements have been revised since the previous Plan. · CLFLWD & Scandia Staff Quarterly Meetings  Meeting held on October 19, 2020.  Meeting on February 9, 2021.  Meeting on May 11, 2021 covered the following topics: · Lake Management District Updates · Bone Lake projects status · Greenway Corridor Planning & Parks · Roadway projects · CMSCWD Managment Plan · Bone Lake H&H Modeling Update at 5/13 Board Meeting. · Meeting on September 13, 2021 covered the following topics: · Permitting Update · Roadway Projects · Tiller Mining and WD Boundaries · Bone Lake projects status (SE wetland restorations, NE wetland restoration, agricultural practices) · FY22 Clean Water Fund grant application – Moody Lake projects · Greenway Corridor Planning & Parks · CLFLWD Watershed Management Plan · CMSCWD Watershed Management Plan  Meeting on May 11, 2021 covered the following topics: · Permitting Update (Nick) · Roadway Projects (Ken) · Bone Lake projects status: SE wetland restorations, NE wetland restoration, agricultural practices (Blayne) · FY22 Clean Water Fund grant award – Moody Lake projects (Emily/Blayne) · Greenway Corridor Planning & Parks Update (Nick) · CMSCWD Management Plan (Mike Isensee) · MnDOT/Washington County – Hwy 97 & Oakhill/CR 52  First initial contact/conference meeting with MnDOT to discuss issues and concerns with intersection safety on October 13, 2020. · This work has been completed; 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.  County Road 52/Oakhill · City Council Workshop on June 2, 2021; Scandia City Council heard concerns residents who live along Oakhill Road, east of the business area, where they have observed speeding traffic and parking issues. One resident who lives at the site of the 30 mph zone remarked that the majority of drivers do not slow their speed at all and race in and out of town, causing safety concerns for the many pedestrians and bicyclists who share the road. · Washington County has scheduled a meeting with City Staff on June 21, 2021 to discuss the concerns brought forward to the City Council. · Coincidentally the County has been communicating with the City Engineer to discuss Oakhill, Highway 97, and Olinda Trail. We think this is a good time to have a conversation about overall traffic flow, pedestrian connections, speeding, bike routing, school issues, etc. in the “downtown” Scandia area and potentially start to develop a joint strategic plan for this entire area – including engaging MnDOT about improvements to highway 97. · Washington County Projects  County Highway 3 (Olinda Trail) · Construction begins summer 2022. · Location - Olinda Trail (County Highway 3) from 170th Street (County Highway 4) to Old Marine Trail. Proposed Improvements – replace pavement full depth, increase road and shoulder pavement thickness, culvert cleaning and driveway culvert replacements, new signing and striping, driveways will be tapered with gravel to provide access to and from the roadway. · Schedule – August 2022 to September 2022 anticipated.  County Highway 15 (Manning Avenue) Pavement Improvement Project · Construction begins summer 2022. · Location – from Lynch Road to 240th Street N (County line). Proposed Improvements – cold in place recycle of existing pavement, increase road and shoulder pavement thickness, widening of turn lanes, culvert cleaning and driveway culvert replacements, new signing and striping, replace mailboxes, improve drainage, driveways will be tapered with gravel to provide access to and from the roadway. · 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.  Recommendations from consultants were to: 1. Conduct a GIS-based flood hazard assessment and workshop and 2. Model both historical and projected rainfall data to evaluate current design practices and inform future planning and management decisions.  CMSCWD has a completed Hydraulic and Hydrologic Model that was updated and calibrated in 2021. This model will be the foundation for any future climate resiliency modeling we conduct.  CMSCWD has identified climate resiliency/floodplain risk assessment work to be conducted in the 2023 in the CMSCWD Draft 10 Year Management Plan. The public comment period for the Management Plan ends October 15th and the public hearing for the final plan is scheduled for November 18th.  Staff is working with our respective boards to approve submitting a collaborative grant application to the MPCA by December 21st. (Planning grants for stormwater, wastewater, and community resilience)  From the December 8, 2021 CMSCWD Board Meeting Minutes: · Administrator Isensee reminded the Managers of a prior presentation by EOR to partner with CLFLWD and BCWD to review floodplain mapping and flood risk assessment across the 3 watershed districts to better prepare for large rain events and/or flooding. The proposal is for 4 organizations (CMSCWD, CLFLWD, BCWD, and MSCWMO) to jointly apply for a grant for resiliency planning. Manager White moved for Administrator Isensee to work with CLFLWD, BCWD and MSCWMO to submit a collaborative grant application to the MPCA for resiliency planning for an amount not to exceed $116,597 with a match from the CMSCWD of $3,615.00. Seconded by President Johnson.  Still waiting on response from MPCA on status of grant. · Uptown Drainfield System Capacity Review  Recent inspection of interior of pumped-down EQ tank by Smilie’s didn’t detect any apparent sources of I/I – we still don’t know where the additional flow that seems to be reaching the treatment system is coming from.  Recently received some info which confirms flows to the Uptown System, including the now- open café.  After a final review we’re looking at allowing the proposed Heritage Center to connect to the existing system without modification.  Scenario if the Heritage Center would lock the bathroom doors during Amphitheater events and require people to use porta potties: Average (gpd) Max (gpd) System Capacity 3,543 5,062 Existing Flows 2,500 4,000 Heritage Center Flows (no amphitheater) 607 773 Total Future 3,107 4,773 · Regional Update – Highway 243 Osceola Bridge  MnDOT are in process of designing the reconstruction of the Hwy 243/Osceola Bridge over the St. Croix National and Scenic Riverway, in partnership with the Wisconsin Department of Transportation (WisDOT). The Osceola Bridge was built in 1953.  The purpose of this project is to maintain a reliable highway connection over the St. Croix River for Hwy 243 between Washington/Chisago counties in Minnesota and the Village of Osceola and Polk County in Wisconsin. The project team will work with federal, state and local interests to minimizing project impacts to the St Croix River and other natural resources in the area.  Project website: http://www.dot.state.mn.us/metro/projects/hwy243osceola/index.html  Schedule: · Environmental documentation and preliminary design: 2021 through 2023 · Final design: 2023 through 2025 · Anticipated construction: 2025 through 2026 Denise Workcuff Dmitry Tomasevich Communications and Engagement Project manager denise.workcuff@state.mn.us dmitry.tomasevich@state.mn.us 651-775-0025 651-245-4406 · CMSCWD 2022-2031 Watershed Management Plan and Rule Revision  The Carnelian-Marine-St. Croix Watershed District (CMSCWD) has completed the public notification period to consider the Draft Fourth Generation Watershed Management Plan (2022-2031). Final response comments received during the 60-day comment period are attached to this report.  In addition to receiving written public comment, the CMSCWD held two public hearings at the Scandia Community Center, City of Scandia on September 8, 2021 and November 18, 2021 and at which time all interested persons will had the opportunity to address the CMSCWD Board of Managers concerning the proposed draft plan and the draft response to comments. Additional information can be found on the District website at https://www.cmscwd.org/10year-management-plan-update.  There were no comments on the revised rules from the Technical Advisory Committee or from the public comment period. The revised rules were adopted and effective Jan 1, 2022. The following steps have been completed for the CMSCWD Watershed Management Plan with no substantial changes to the draft plan: Public comment period completed, draft response to comments approved by the CMSCWD Board of Managers and posted on the website, second public hearing for the proposed revised plan based on public comment (no additional comments received), final draft plan submitted to the Board of Water and Soil Resources. We anticipate the 2022-2031 WMP will be approved by BWSR in late March and the final plan approved by the CMSCWD at the April 13, 2022 meeting.  As identified in the plan, the CMSCWD hired a permanent full time Riparian Permit Coordinator. He started on January 24. This is the email sent out to staff: Tom Langer earned his Master of Science from Central Michigan University in 2014 where his thesis focused on measuring biodiversity of costal wetland fish and macroinvertebrates. His past ten years of employment experience included positions with a research institute, consulting firm, and a watershed district. He brings a passion for ecology, strong communication skills, and technical environmental experience. Tom will be leading the CMSCWD permitting and riparian landowner technical assistance programs and be involved in many other watershed programs. · Gateway Trail Planning  Meeting with Washington County has been scheduled for Monday, November 29, 2021 to discuss partnership on Gateway Trail Planning opportunities within Scandia. · Martin Marietta Mine (old name Tiller Mine)  Annual site inspection was completed Friday, November 12, 2021. · Small Cities Assistance – Bill would provide dedicated funding for Account  The bill dedicates a portion of the auto parts sales tax to the Small Cities Assistance Account, which provides street funding to cities with populations below 5,000. · A bill passed by the Senate Transportation Finance and Policy Committee on Feb. 22 would provide dedicated funding for the Small Cities Assistance Account, a formula-based program that provides street funding to cities with populations below 5,000. The measure, SF 3086, authored by Sen. Jeff Howe (R-Rockville), dedicates 100% of the sales tax on auto parts to transportation, and carves out 12% of the proceeds for the Small Cities Assistance Account. The bill was passed unanimously to the Taxes Committee. The House companion, HF 3646, authored by Rep. Chris Swedzinski (R-Ghent), has not been scheduled for a hearing. The League testified in favor of dedicating a portion of the funds to cities with populations below 5,000. It is needed since these cities do not receive direct funding from the Highway User Tax Distribution Fund (HUTDF).  Funding Estimates · According to estimates provided by legislative staff, the sales tax on motor vehicle parts currently generates approximately $160 million annually. If SF 3086 passes in its present form, the Small Cities Assistance Account would receive just over $19 million per year. · Another 12% would go to townships and the remaining 76 percent would be deposited into the HUTDF. Existing law provides that the first $12.137 million per month (approximately $145.6 million per year) in revenues from the sales tax on auto parts must be deposited into the HUDTF.
