A. Mr. Kiefer. called the meeting to order at 7:30 am. II. Approval of May 17, 2018 Meeting Minutes. A. Mr. Clark noted spelling Section II B (Citgo, not Citco). Clark moved to approve as amended. Seconded by Mr. Janty. Approved (4-0). III. Program Updates A. Mr. Ferris summarized current work and status of projects including: Knapp Street Relief Storm Sewer (completed), Libbey Nicolet Basin (constructed has started), and South Park project (project is in final restoration phase). i. Mr. Janty asked if the current pond water surface at South Park is near the high-level elevation under operational conditions. Mr. Ferris replied that is the case. ii. Mr. Ferris proposed that the July Committee meeting be held at South Park if the Committee would like a tour. Committee agreed this would be a good idea. B. Mr. Ferris summarized the Prairie Treatment System workshop that was conducted on May 30, 2018. There were 47 participants and a good response from the attendees. C. Mr. Ferris summarized the status of the cityparticipation in the USGS Leaf Management monitoring project. Mr. Ferris is preparing optional areas for the USGS to consider for monitoring in the fall of 2018. Mr. Janty asked for the schedule of the monitoring project. Mr. Ferris replied the monitoring will be conducted in 2018 and 2019 and data analysis / report writing will take place in 2020. D. Mr. Ferris mentioned that there is an Upper Fox / Wolf Basins TMDL stakeholder meeting on July 11, 2018 at the Oshkosh Coughlin Center. Mr. Ferris also presented a simplified, example of a Waste Load Allocation (WLA) and Load Allocation (LA) process for a receiving water. This type of analysis will be conducted for each reachshed within the TMDL area. The City of Oshkosh will have four reachsheds with WLAs for its storm sewer (MS4) system when the TMDL is issued. IV. Review Proposed 2019 & 2020 CIP Projects A. Mr. Ferris summarized the proposed capital projects for the 2019 CIP budget: i. Jeld-Wen outfall: The main part of this project is land acquisition and/or easement; and a new . The landowner is not sure of future development plans for the Cost estimate is $1,760,200. ii. East Parkway Ave. Basin: This project is a dry basin enhancement to gain water quality credits. The project requires land acquisition from CN railroad and possible acquisition of a residential property. The land acquisition process will delay construction until 2019. Cost estimate: land: $60,000, Construction: $750,000 iii. Wetland Mitigation: This project is ongoing and identification of suitable land is not finalized. Estimated budget: $1,400,000 (2019 land acquisition); and $327,600 (2020 design). iv. Mini-storm sewer: In 2017, 39 projects were funded and installed. In 2018, 33 projects are scheduled and funded, ($400,000), and 2019 has 41 projects scheduled ($450,000). The 2018 contract for this work will be on Council agenda. More projects for 2018 are being added. 2020 CIP is anticipated at $450,000 v. Waukau Avenue Bridge (on Gallups Creek): Design work is under way and $700,000 construction cost has been estimated for a 2019 implementation schedule. vi. Septic Haulers / Street Sweeper Disposal Upgrade Relocation Study: Currently, private septage and city street sweeper material are dumped at the wastewater plant at a receiving area off Dempsey Trail. The site is difficult to maintain and adds phosphorus to the wastewater treatment process. Future budgets call for: 1) a study of alternative methods to handle septage and street cleaning debris (2019 $75,00); 2) design of a receiving facility (2020, $125,000); and 3) construction of a facility ($1,000,000, 2021). Ms. Muldoon asked if street cleaner hoppers could be dumped at the current yard waste site. Mr. Ferris replied that at the yard waste drop-off site, rain runoff would enter the storm sewer system and this would not be acceptable. An improved disposal site for the street cleaner solids needs to be developed. Lab analysis of the current material at the disposal site shows very high phosphorus and mercury levels. vii. Kentucky Street Storm Sewer (near Merrill School): Storm sewer is proposed to be added at this location to allow the school system to construct paved parking on open lots (west side of Kentucky St.). There are no current storm sewers in Kentucky St. at this location. viii. Universal Court Storm Sewer Connector: Add approximately 1,600 ft. of new storm sewer to allow for new development northwest of Outlet Mall. This project will likely require an easement for the storm sewer. This project was not identified at the May 2018 meeting and no budget has been developed yet. ix. Gallups-Merritts Creek & Johnson Ave. Preliminary Engineer Study: Improvements from potential airport drainage upgrades will require the city to study downstream improvements th at a culvert crossing of a taxiway, along the channel (north of W. 35 Avenue) and in other the areas. No budget was estimated at this time. B. Mr. Janty asked about total capital costs for the stormwater capital program. Mr. Ferris replied between $4 $6 million, not including storm sewer components of street projects. C. 2020 CIP i. Moser Street Storm Sewer: Snell Road is scheduled for reconstruction in 2019 from Jackson Street to Moser. In 2020 an improved storm sewer from Snell to East Fernau Ave is cost estimate at this time. nd ii. 2 Fernau Watershed Basin: This project is on hold until further notice. No funding is planned for 2018 or 2019. Currently land acquisition is planned for 2020. iii. Westowne Basin: Land acquisition and conversion of a dry basin to a wet basin. The land acquisition process is still ongoing, and hopefully will be completed for a 2019 implementation. No capital budget estimate at this time. Implementation is scheduled for 2020. iv. Annual Parking Lot Retrofit Program: This is a proposed new program. The city is looking at adding stormwater treatment as city-owned parking lots are reconstructed. The treatment is in anticipation of TMDL requirements. The City owns 57 lots and these would v. Annual Ditch Restoration Program: City is planning on a comprehensive maintenance / restoration effort on city-owned / operated open channels. The work will require DNR permitting and vegetation control. The purpose of the work is to improve the hydraulic capacity of the channels. The estimates on costs and length of ditching are not estimated yet and this would be an ongoing effort. This work may stormwater vegetation management contractor. V. Review A. Mr. Ferris asked the committee how much effort should go into managing vegetation at the stormwater basins. Should some basins receive more priority than others? Initial budget estimate for vegetation management is $50,000 - $70,000 per year. Mr. Kiefer asked if the vegetation is affecting the functionality of the basins. Mr. Ferris responded that at times an overgrowth and die-off of cattails can cause clogging of outlets, but probably does not impact the overall functionality of a basin as far as pollution reduction. The committee generally agreed that maintaining the aesthetics of t keeping public support. The committee commented that basins could be prioritized by visibility and public exposure to determine where maintenance costs should be focused. i. Mr. Janty suggested the city consider if any of the sites could be future park or public use areas. ii. Mr. Clark recommended a scoring system for stormwater basins similar to the streets program for maintenance needs. iii. 18 management efforts. Next meeting will be at the South Park Shelter V. Discussion of Future Meeting of Agenda Items. A. Mr. Janty would like to hear how other cenance. B. Mr. Janty asked for ERU changes over the past 3 4 years and projected changes. C. Mr. Kiefer requested a list of the actual CIP submittal projects be made available to the committee. VI. Adjournment. A. Mr. Butler/ Mr. Janty moved and seconded to adjourn the meeting at 8:50 am. Motion passed (4-0). Respectfully Submitted John Ferris, PE, Civil Engineer Supervisor
