I.Call to Order.
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).
