Call to Order. A. Mr. Kiefer called the meeting to order at 7:33 am. II. Approval of June 23, 2022 Meeting Minutes. A. Motion to approve June 23, 2022 minutes (Mr. Clark / Mr. Ulrich). Approved 3-0. III. Review of Storm Water Utility Progress Maps (Brown and Caldwell). A. Mr. Wegner introduced the topic and provided an overview of the map updates. Hard copies of the maps were provided to board members, the maps had previously been distributed electronically. The update included revisions to the progress maps previously created and reviewed by the board. The last update occurred in 2015. The updated maps followed the format and style of the prior maps. In addition, two new maps were created. B. Two items were noted regarding the maps from Mr. Clark. On the printed versions the green shading does not show up well and makes the maps harder to read. Additionally, on the mini-storm program map, the red dots do not look good. Mr. Wegner indicated these colors would be reviewed and changes would be tested on City printers to verify they look good on future maps. C. Map A-4 - Mr. Ulrich asked about the scheduled work shown on Map A-4 near “La Sures” and whether it was already being done as part of private development in the area. Mr. Gierach said the project shown was a reconstruction of Ripon Avenue and it was recently bid for construction. The contractor is hoping to start work this fall. This road was previously in the Town of Nekimi and the project will install water and sewer utilities. D. Mr. Kiefer asked what the difference is between planning level and detailed studies as shown on the flood studies map. 1. Mr. Wegner indicated planning level studies were mainly completed as part of the 2008 Citywide SWMP and looked at larger storm sewer to try to identify problem areas. Detailed studies look at all storm sewers and focus on finding solutions to flooding and sizing new infrastructure. Mr. Gierach added that planning level studies could be thought of as a 40,000 foot view and detailed studies could be thought of as a 10,000 foot view of the storm sewer system. E. Mr. Clark commented about how the mini-storm sewer program map shows a lot of participation in the Miller’s Bay area and asked about the potential correlation to a lack of detailed studies in this area. 1. Mr. Gierach said this issue is likely due to the age of development in the area. The streets and utilities haven’t reached the age where they need to be replaced. But the development occurred prior to rigorous stormwater planning and standards. He said there have been some issues and it is on the City’s radar for future study and work. F. Mr. Ulrich asked about the severity of the June 2008 flood event and if it was a 500-yr storm. 1. Mr. Wegner said that the flooding resulted from back to back large events. The first event was in the range of a 25-year storm. The second event happened about 4-5 days later and was in the range of a 75-year storm. However, the ground was saturated and water levels were elevated from the prior event. This resulted in flooding that was equivalent to a larger event, likely in the range of a 100-year storm. G. Mr. Clark asked about the process for finalizing the maps and whether an action item was needed. August Storm Water Utility Board Minutes 8-18-2022 Page 2 of 3 1. Mr. Gierach was unsure if an action item was needed, the City is looking to get the maps finalized and published. 2. Mr. Clark asked the City to look at past meeting minutes for what happened as part of prior map updates and that if needed an action item could occur in September. H. Mr. Kiefer and Mr. Clark both expressed that the maps looked good and indicated their positive feedback of the maps. II. Review of Johnson Avenue Watershed Storm Water Management Plan (AECOM) A. Ashley Leisgang from AECOM gave a presentation regarding the Johnson Avenue Watershed study that was recently completed. B. The presentation gave an overview of the study area, goals, existing conditions analysis, alternatives analysis, cost estimates, and the selected alternative. The analysis resulted in the selection of Alternative 6, which provided the greatest flood mitigation benefits. C. Following the presentation, the floor was opened for questions. 1. Mr. Kiefer asked about the residential area near the downstream end of the project area where the creek enters Lake Winnebago. He asked whether it was within the City or in the adjacent Town. Mr. Gierach and Ms. Leisgang said that the majority of the area was in the City. 2. Mr. Leisgang said that as part of the recent work in the Fond du lac Road area some of the recommended improvements from the study (storm sewer enlargements) were installed on Waukau Avenue. 3. Mr. Clark asked about the future road construction work that is scheduled on Oregon Street and whether this work would be implemented as part of that. Mr. Gierach said that the improvements in Alternative 6 would be within the future road construction project area and this work will be coordinated with the upcoming work. The storm sewer work is budgeted for 2024 in conjunction with the state project on Oregon Street, and the City will work through details to try to coordinate the work. The City project may need to occur after the state project due to difficulties in coordination and previous agreements in place regarding other utilities. The worst case scenario is the culvert would require a crossing of the street after the state project is done, but impacts would be minimal. D. Mr. Gierach said that the City would like to modify this agenda item to have the board approval of the study so that it can be finalized. E. A motion was made to amend Item IV to “Review and Approve of Johnson Avenue Watershed Storm Water Management Plan” (Mr. Clark / Mr. Ulrich). Approved 3-0. F. A motion was made to approve the Johnson Avenue Watershed Storm Water Management Plan as presented by Ms. Leisgang (Mr. Clark / Mr. Kiefer). Approved 3-0. III. Program and Project Updates (J. Gierach). A. 22-01 Bowen Sanitary Sewer/Storm Sewer 1. Project is scheduled to start early spring of 2023. WPS is currently working on relocating utilities in advance of the project. B. 22-02 E. 9th Avenue 1. Project is also scheduled to start in early spring 2023. C. 22-04 Algoma Boulevard & Vine Street Reconstruction 1. Contractor is currently working on Algoma Boulevard. The utilities are done. Phase 1 of concrete paving is in progress and the contractor is working on paving the 2nd side of the street. They will then move to Phase 2 for concrete paving. The phases are split based on a UW-Oshkosh steam tunnel project that is on-going. The City is coordinating with the university regarding the tunnel project. 2. Mr. Kiefer asked about when move-in will occur for UW Oshkosh and if the road would be open. Mr. Gierach said that move-in is Labor Day weekend. The road will not be open. The road will be paved in front of the campus, but not open to traffic and the contractor will be continuing to work August Storm Water Utility Board Minutes 8-18-2022 Page 3 of 3 on sidewalk, lights, and landscaping. The project will not quite be done prior to start of school as previously hoped. D. 22-05 East Lincoln & Rosalia Street Reconstruction 1. Work on Lincoln Street is complete. 2. On Rosalia Street the contractor is working on concrete paving of the 2nd side of the street. E. 22-07 Oregon Sanitary Sewer 1. The project is scheduled to start next week. F. 22-20 Mini Storm 1. This project is progressing well and is close to being finished. G. An update on 2023 projects was also provided. 1. Mr. Gierach said the City is working on design of the 2023 construction projects and is planning to bid the projects in the fall of 2022, which is ahead of schedule compared to previous years. 2. Mr. Kiefer asked about the CIP that was previously reviewed by the board and whether there were any changes. Mr. Gierach stated that there were no changes through the City Manager review. Earlier this week it was presented to plan commission. 3. Mr. Gierach also provided an update on the Sawyer Creek – Rural II detention basin. The City is currently working with Strand on land acquisition. They will get appraisals back soon, and then hope to have purchase offers sent out by the end of August. Design will be worked on this fall/winter with construction for summer/fall 2023. i. Mr. Clark asked if the current landowners are willing sellers? Mr. Gierach said that one is willing to sell. The City is currently unsure about the 2nd landowner. He said that the City may need to use the full eminent domain process. The City is following the process as part of the 1st steps in land acquisition and will continue if needed. ii. Mr. Kiefer asked if the appraisals were a challenge due to location of the property and the potential for future development. Mr. Gierach said it is not an easy location for appraisals, but that the parcels are not the easiest area for development either due to their location. iii. Mr. Clark stated that it is possible there are other residents in the Town of Algoma that may be opposed to the project who are pushing the landowner to oppose the sale of the land. iv. Mr. Gierach said that the ongoing work towards creating the flood storage districts along Sawyer Creek with Winnebago County may also be a factor in opposition. IV. Review Discussion of Future Meeting Agenda Items. A. Tour of Storm Water facilities (tentative for a meeting after board positions are filled). B. Storm Water Rates/Finance Discussion by Ehlers (September?). 1. Mr. Clark asked if an update on the total money spent on stormwater projects by the Stormwater Utility could be provided. He indicated that this information helps him discuss with residents that the City is committed to continuing to fix problems and is evidence of the work done to date. C. Mr. Wegner indicated that at the September meeting the Citywide SWMP Update would be presented and the City would be looking for the board to review and approve the plan. Materials for the project would be provided prior to the meeting. V. Adjournment. Mr. Gierach noted that this is the last morning meeting. The next meeting will be Wednesday, September 28 at 4:30 pm. Mr. Kiefer asked if there were any other items that needed to be discussed. Hearing none, a motion to adjourn was made and seconded: (Mr. Kiefer / Mr. Clark ) Approved 3-0. Adjournment at 8:31 am.
