MEMORANDUM
DATE: March 19, 2015
TO: Honorable Mayor and Members of the Common il
FROM: James E. Rabe, Civil Engineering Supervisor
RE: 2014 Storm Water Program Annual Report
BACKGROUND
The City of Oshkosh received coverage under the Wisconsin Department of Natural Resources (WDNR)
Municipal Separate Storm Sewer System (MS4) General Permit on January 2, 2007. In May, 2014, the
City of Oshkosh notification that this coverage was extended to include the newly release version of the
MS4 General Permit. This permit requires the City to comply with the following six minimum control
measures (as mandated by the Federal Clean Water Act and the Environmental Protection Agency):
1. Public Information and Education Plan
2. Public Involvement and Participation Program
3. Illicit Discharge Detection and Elimination Program (including new or revised ordinances)
4. Construction Site Pollutant Control Program (including new or revised ordinances)
5. Post-Construction Storm Water Management Program (including new or revised ordinances)
6. Pollution Prevention Program (Prevent pollution from the daily operations of the City)
The Storm Water Utility Committee reviewed the Annual Report and recommended approval as
discussed during their March 19, 2015 meeting.
ANALYSIS
The annual report contains information on the activities performed by the City of Oshkosh in compliance
with the MS4 Permit requirements. This report includes the completed WDNR form, as well as
supplemental information that the WDNR Form did not have room to enter. The final year end financial
data is still being compiled by the Finance Department, and the final 2014 expenditures may be slightly
different that those shown in the table. City staff has more details available for the WDNR, should they be
requested.
FISCAL IMPACT
There is no anticipated fiscal impact from the approval of this resolution.
RECOMMENDATION
Staff recommends approval of the resolution.
Approved:

a.Minimum Control Measures:
Public Education and Outreach
There were two informational signs set up throughout the construction of the Armory Area Wet Detention
Basin during 2014. One sign was located in the residential neighborhood that borders the north side of
the project. The second sign was located adjacent to the commercial parking lot on the west side of the
project. Throughout the construction,numerous residents were observed watching the construction while
eating lunch and reading the information signs.
The Storm Water Utility Committee was given the opporlunity to visit the Armory Area Detention Basin
during construction,and the recently completed James Road Area Detention Basin at their July l Oth
meeting.
Staff conducted Erosion Control Conferences("Ground Control Conference")for five major construction
projects in 2014. The General Contractor is required to have their site supervisor and foreman in
attendance. Sub-Contractors that have not gone through a ground control conference in the past year are
also required to have staff in attendance. City staff spend approximately one hour with each project going
through project specific erosion and sediment control requirements,watching a video on erosion and
sediment control, and discussing the City's procedure for conducting inspections and sending notification
of corrections needed.
Civil Engineering Supervisor James Rabe and Strand Associates, Inc Project Manager Matt Yentz
presented at the 2014 Fox Wolf Watershed Alliance Annual Conference. The presentation was a "Case
Study" of the various Storm Water Management and Flood Management strategies employed by the City
of Oshkosh over the past five years. The presentation highlighted six projects that the City had
constructed between 2009 and 2013.
Civil Engineering Supervisor James Rabe and Strand Associates,Inc Project Manager Matt Yentz worked
with Communications Coordinator Emily Makowski to record the presentation given at the Fox Wolf
Watershed Alliance in the Oshkosh Community Media Services (OCMS)studio. The presentation then
aired on OCMS local cable channel,"On Demand"on the OCMS website,and as part of a program loop
that airs on a television in the lobby of City Hall. A link to this recorded presentation can be found on
the City's Storm Water Utility webpage
(http://www2.ci.oshko sh.wi.us/PublicaWorks/Storm=W ater�Utilit�).
On September 23`d,Civil Engineering Supervisor James Rabe gave an"Introduction to Storm Water"
presentation to the University of Wisconsin—Oshkosh students taking the Introduction to Sustainability
course. The presentation introduced students to what storm water runoff is,and what some of the
challenges are in dealing with storm water runoff.
Informational Signs were installed at several City owned storm water management facilities in 2014. All
the signs carry similar City-Wide messages,but also contain watershed or site specific messages as well.
The City currently has signs installed at the following locations: Fair Acres Detention Basin,Oshkosh
North High School Area Detention Basin,Baldwin Avenue Area Detention Basin,Westhaven Clubhouse
Area Detention Basin,Melvin Avenue Storm Water Pump Station and Tipler Area Detention Basin
Staff interact with property owners on a daily basis and continually provide education and outreach to the
residents,business owners,and others doing business in the City of Oshkosh.
Public Involvement and Participation
The Storm Water Utility has a page on the City's Website. The Storm Water Utility Engineering
Supervisor works with the Information Technology Division staff to ensure that items pertaining to the
Storm Water Utility that may be of interest to the general public are posted. The url for the Storm Water
Utility webage is: http://www2.ci.oshkosh.wi.us/Public Works/Sto�Water Utilit�
In 2014,the Storm Water Utility Committee held public meetings on: January 16,February 20,March 20,
May 1,June 12,July 10,August 21,October 2,November 6 and December 11. All Storm Water Utility
Committee meetings are open to the general public,and are publicly noticed in accordance with state
statutes. A link to the Storm Water Utility Committee agendas and minutes can be found on the City's
Storm Water Utility webpage.
The 2013 MS4 Annual Report was discussed at the February 20 and March 20 Storm Water Utility
Committee Meetings. The report was also posted to the Storm Water Utility webpage. The Common
Council reviewed and voted to approve the report at their March 25th meeting.
The Storm Water Utility Committee was given the opportunity to visit the Armory Area Detention Basin
during construction,and the recently completed James Road Area Detention Basin at their July lOth
meeting.
Staff inet with businesses within the Fernau Avenue Watershed to discuss status of the Storm Water
Management Plan analysis. The primary goal of preliminary meetings such as these are to inform the
businesses of the status of the ongoing analysis,as well as review existing conditions model efforts to see
if the model reasonably depicts the level of flooding experienced during real storm events. This effort to
calibrate the model to real storm events is essential to ensuring the reliability of the modeling throughout
the remainder of the analysis.
Illicit Dischar�e Detection and Elimination
Outfall screening program completed first four year cycle in 2013. 2014 is a"transitional"year between
the initial screening program,and the development of the revised ongoing screen program. The revised
ongoing screening program will be developed based upon information gathered and lessons learned
during the first four year screening cycle.
During 2014,42 outfalls were"re-screened"from previous years. These 42 outfalls were selected due to
the potential for illicit discharges to be present based upon the previous years. A1142 of the outfalls are
partially or fully submerged. Of the 42 outfalls screened, 17 had potential illicit discharges. 14 of these
due to floatable debris,2 due to detection parameters out of range,and 1 due to potential petroleum.
Previous years detected a number of manholes with an accumulation of floatable debris. This floatable
debris collects in manholes in the submerged storm sewer system. The Streets Division vacuums the
debris from the manholes after the inspection reveals the presence. The continued presence of floatable
debris could be the sign of an ongoing issue,or it could be due to manholes further upstream having
accumulated floatable debris that has not yet been removed from the system. The City will perform a
more thorough analysis of these submerged systems to determine if additional cleaning of the system is
required.
A copy of the 2014 Outfall Screening Report has been submitted under separate cover.
A summary table of phone calls received in our office regarding illicit discharges(primarily grass
clippings being deposited in the street)is attached to this report.
On Friday,October 24, 2014,DNR Northeast Region Spills Coordinator,Beth Erdman contacted the City
Engineering Division to request assistance in tracking a discharge into Gallups/Merritts Creek. The
Department had been contacted by residents reporting that Gallups/Merritts Creek was flowing white.
Department staff tracked the discharge to the City's storm sewer system outfall on 35`h Avenue. City staff
met Department staff onsite and assisted with the tracking and containment of the discharge until the
discharging party could contact appropriate assistance to contain/clean up the discharge. DNR remained
the lead agency on the case,with the City providing assistance as requested.
Construction Site Pollutant Control
The City inspects all municipal construction projects on a weekly basis,and after rainfall events in excess
of one half inch in twenty four hours. The Contractor is issued orders to repair any deficiencies in the
implementation of the Erosion and Sediment Control Plan within 24 hours. The City utilizes a mapping
grade handheld GPS unit to locate any deficiencies in the erosion and sediment control practices,and
provide the contractor a map of the locations needing repair. The City also inspects all municipal
construction projects that remain"open"over winter to ensure that practices are in place and functional as
the ground begins to thaw.
The City inspected each Commercial/Industrial development for compliance with their Erosion and
Sediment Control Plans on average 1-2 times throughout the construction season. Any deficiencies noted
in the implementation of the Erosion and Sediment Control Plan were noted in a letter emailed to each
construction manager. Additionally,the City responds to numerous citizen complaints due to erosion and
sediment control. These complaints are notably after storm events when tracking from construction sites
frequently occurs. As with"random" inspections,a summary inspection letter is sent to the construction
manager for the site.
City staff performed a total of 238 construction site erosion and sediment control inspections in 2014.
Approximately 200 hours were spent on the inspections,with approximately another 50 hours or so spent
in the office preparing reports to send to contractors.
Post-Construction Storm Water Management
Staff completed 109 private site development plan reviews through the course of 2014, spending
approximately 340-350 hours on those plan reviews.
Pollution Prevention
Approximately 3,000 person-hours were spent cleaning and removing sediment from catch basins.
Approximately 14,000 curb miles of street sweeping occurred in 2014. There are approximately 280
miles of street in the City of Oshkosh. Each mile of street equals 2 curb miles(1 on each side of the
street). The approximately 14,000 curb miles of street sweeping equates to sweeping each street
approximately 25 times throughout the year. Street sweeping starts in April-May and continues into
November in an average year.
Road Salt application vehicles are calibrated per the manufacturer's recommendations. The Streets
Division Supervisors have pavement temperature sensors equipped in their trucks,to monitor the
temperature of the pavement to ensure that salt is not being applied when it will not be beneficial.
e.Best Management Practices Maintenance:
The City of Oshkosh Streets Division inspects the major storm water BMP's after each major rain event.
These inspections look for any evidence of damage,plugging or other concerns. Any deficiencies noted
are repaired as quickly as possible.
The City Waste Water Treatment Plant Staff maintain all pump stations in the City of Oshkosh(waste
water and storm water). The City has one large storm water pump station(Melvin Avenue Storm Water
Pump Station). The station is monitored 24 hours a day, 7 days a week, 365 days a year via radio
telemetry by operations staff at the Waste Water Treatment Plant. The station is visually inspected on a
weekly basis by a Maintenance Mechanic. The backup power generator is tested 3-4 times per year. The
backup power generator was serviced in April by supplier maintenance staff. The wet well was cleaned
and inspected in June,2014.
Engineering Division Staff inspects each storm water BMP annually. These inspections focus on
potential structural damage to the facility due to erosion,rodents,vandalism,or other causes. Any
deficiencies noted are repaired as quickly as possible. In the case of rodent damage,the site is then
evaluated for potential actions to reduce the rodent population.
The City contracted with McMahon(Neenah,Wn to conduct vegetation monitoring and maintenance at
two of our recently constructed detention basins. This vegetation monitoring and maintenance program
helps the native vegetation become properly established,thus reducing long term operation and
maintenance concerns.
The City of Oshkosh contracted with Suburban Wildlife Solutions,LLC(Kaukauna,WI)to conduct
nuisance animal inspections and trapping at all wet detention basins owned and operated by the Storm
Water Utility. The management of nuisance animals(muskrats for example)is vital to ensure the long
term stability of the detention basins. In addition to the wet detention basins, Suburban Wildlife
Solutions,LLC performed monthly inspections of the berm at the James Road Area Detention Basin. If
the inspections showed evidence of burrowing animals,trapping activities were initiated to remove the
burrowing animals and reduce/eliminate the potential damage threat to the berm.
