MEMORANDUM
DATE: August 6, 2020
TO: Honorable Mayor and Members of the Common Council
FROM: John Fitzpatrick,Assistant City Manager
RE: Professional Services Agreement for 2020 Storm Water Facility Native Planting
Maintenance/NES Ecological Services ($38,405)
In May 2016, the Department of Public Works selected Applied Ecological Services, Inc. for the
development of a Storm Water Detention Basin Vegetation Maintenance Program for the many
City-owned detention basins. In 2017, the Department selected NES Ecological Services (NES)
to implement this work.
The original agreement with NES was for a three (3) year term, which ended in 2019. Due to
their experience with the City's storm water facilities' plantings and their technical
qualifications, staff asked NES for a proposal to extend these services for one(1)year(2020).
Engineering Division staff reviewed the proposal and proposed costs. The proposed fee is
$38,405. Funds for these services are budgeted in the Storm Water Utility's 2020 Operating
Budget.
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a
specialized nature, including engineering services, may be procured without the use of formal,
sealed quotes. In accordance with Section 12-16 of the Code, I am hereby submitting this report
regarding this professional services agreement.
Please contact me if you have any questions concerning this professional services agreement.

RE: 2020 Stormwater Facility Native Planting Maintenance
Dear Mr. Gierach:
NES Ecological Services(NES) is pleased to submit this proposal for the maintenance of native plantings
within and around 13 stormwater facility located in the City of Oshkosh, Winnebago County, Wl. The
proposed scope of services for the maintenance,cost and schedule are outlined below.
SCOPE OF WORK
Tasks referenced below can be found in the 2019 City of Oshkosh Stormwater Facility Assessment
Report.
9t" and Washburn Basin
The wetland areas will require intensive work and needs to be addressed over a period of time if a healthy
native community is to be established. The primary concern within this community type is the
elimination of purple loosestrife and cattail. Recommendations are as follows:
• In the wet meadow and prairie communities, we suggest timely herbicide applications (Task 6) .
and selective hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive
forb species. Species to be addressed during these site visits include but are not limited to:
Canada thistle, bull thistle, burdock, cattail, Queen Anne's lace, crown vetch, purple loosestrife,
reed canary grass,sweet clover,common teasel and Kentucky bluegrass.
• NES recommends continued herbicide treatments of cattail to fully eliminate the populations in
the emergent community. Spot treatments and hand wicking will be the most applicable as the
population has been depleted to the point where broadcast applications won't be necessary.
Cattail populations can be greatly reduced in the first year of treatment; however, if follow-up
treatments are not conducted in the years following, the species can easily re-occupy the
previously infested area. As these populations are eradicated, seeding and/or planting of native
vegetation may be recommended to help reduce future invasions by non-native species and
establish a native community.

City of Oshkosh Native Planting Maintenance Proposal
• Follow-up woody vegetation control around the pond's perimeter will be conducted(Task 14). If
left unchecked, woody vegetation could populate the entire shoreline and wet meadow
community making future pond maintenance activities more difficult. Trees could compromise
berms and extensive willow thickets could eliminate desirable herbaceous vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed, A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
Armory Basin
This basin will require intensive work and needs to be addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:
• An early spring, broadcast herbicide treatment targeting broadleaf invasive species, particularly
common teasel and wild parsnip shall be conducted (Task 6). The timely herbicide treatment
would be conducted to target the above listed species prior to native forb species emerging. A
post-treatment evaluation should then be performed to determine native species density within the
planting. If >60% native cover is noted later in the season, a regular maintenance schedule
should be implemented moving forward to keep a positive trend in native species establishment.
If less than 60% cover is observed, the prairie community would need to'be over-seeded or re-
seeded depending on the actual cover of native species.
+ Due to the density of invasive species present, the site likely has a significant seedbank that may
need to be depleted prior to re-establishing native vegetation. If the above herbicide application
is not successful, additional herbicide applications will be required. The process could require
two or three years of herbicide treatments. If redoing the prairie is a priority,the process should
continue by conducting two additional herbicide applications during the 2020 growing season to
remove all vegetation followed by the installation of native grass seed in the fall. Because the
dominant invasive species are forbs, a broadleaf selective herbicide can then be used to
repeatedly treat the prairie area two to three times per year for another year or two until invasive
species control has been achieved, A native prairie seed mix containing primarily wildflowers
can then be over-seeded on the site to increase vegetation diversity.
• If budget doesn't allow the potential re-seeding of the prairie community at this time,two timely
mowings(Task 7 & 8)shall be conducted to prevent teasel and thistle seed production. Repeated
mowing may also help reduce these species populations over time and give native vegetation an
opportunity to grow. Mowing however will not control crown vetch; therefore, spot herbicide
treatments(Task 6)will still be necessary to control this species.
• To achieve a"Good" ranking for this basin, cattail will need to be eliminated from the emergent
zone. Based on the current condition of the emergent zone, broadcast herbicide applications
(Task 6)will be required in 2020.

• Follow-up woody vegetation control around the pond's perimeter shall be conducted(Task 14),
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to

work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1),
Aviation Basin
The site's overall "Best" condition reduces maintenance activities and the time it takes to cover the site;
however, the fencing structure over the basin offsets that by increasing implementation time due to
reduced access and maneuverability for staff and equipment. Recommendations are as follows:
• We recommend selective herbicide applications (Task 6) and hand pulling/cutting/mowing(Task
8)be conducted to target cool season grasses and invasive forb species. Even these tasks may be
difficult to conduct near the slope top because the fencing is only a foot or two off the ground.
Extreme care will need to be taken when conducting tasks within the basin to avoid injury from
the fencing. Species to be addressed during these site visits include but are not limited to: thistle
spp.,burdock, Queen Anne's lace,reed canary grass,and sweet clover.
• Cattail is the only invasive species within the emergent zone that is of concern. Due to the low
density,control shall be performed by hand wicking plants(Task 6).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to

and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
Baldwin Basin
This is a high priority basin for the City due to its high visibility. To achieve the City's desired goal,
significant effort will be required to control primarily cattail, purple loosestrife and woody species.
Recommendations are as follows:
• A spring prescribed burn is recommended (Tasks 4 & 5). The burn will eliminate previously
treated cattail thatch, set-back cool season species, assist with woody species control and blacken
the earth which will spur the growth of native species. If water levels within the basin do not
allow a spring burn, attempts could be made to complete the task in fall. However, if burning is
not feasible, the cattail patches should be mowed (Task 7) in late winter/early spring to allow for
easier follow-up herbicide treatments.

• In the higher quality wet meadow segments, we suggest timely herbicide applications (Task 6)
and selective hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive
forb species. Species to be addressed during these site visits include but are not limited to: thistle
spp., Queen Anne's lace,purple loosestrife,reed canary grass,hybrid cattail and sweet clover.
• Any remaining dense cattail populations shall be broadcast sprayed while scattered plants will be
hand wicked (Task 6) to reduce impacts to the native species. Due to the high quality wet
meadow adjacent to these stands, it is likely native species will re-populate the sites. The treated
areas will be monitored to determine follow-up activities.
• Follow-up woody vegetation control throughout the basin shall be conducted (Task 14). If left
unchecked, woody vegetation could populate the entire wet meadow community making future
pond maintenance activities more difficult. Trees could compromise berms and extensive willow
thickets could eliminate desirable herbaceous vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to

(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
Fair Acres Basin
The wetland area has endured intensive herbicide treatments to control hybrid cattail. Monitoring of the
wetland area will need to be done in order to determine the need for planting within the zone. The upland
area will also require work to control invasive species. Recommendations are as follows:
• In the prairie community, we suggest timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing(Task 8)to target cool season grasses and invasive forb species. Species
to be addressed during these site visits include but are not limited to: thistle spp., burdock,Queen
Anne's lace, crown vetch, purple loosestrife, reed canary grass, sweet clover and Kentucky
bluegrass.
• To achieve a better ranking in the emergent zone,native species will need to begin re-populating
the zone and any remaining cattail will need to be addressed via spot treatments or hand wicking
in order to prevent the species from re-populating.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments

(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
Fernau Basin
Since this basin is in its early stages of development, routine maintenance of mowing and spot herbicide
treatments should improve the condition of the basin. Recommendations are as follows:
• In the prairie community, we suggest timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing(Task 8)to target cool season grasses and invasive forb species. Species
to be addressed during these site visits include but are not limited to: thistle spp.,burdock,Queen
Anne's lace, crown vetch,purple loosestrife,reed canary grass, sweet clover, common teasel and
Kentucky bluegrass.
• Cattail is the only invasive species within the emergent zone that is of concern. The population
has been reduced to little coverage of scattered plants interspersed throughout the emergent zone,
but control should continue to be performed through spot foliar treatments and/or hand wicking
(Task 6).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the"assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
James Road Basin
The rather large basin has the potential to provide good native species diversity and cover; however,
maintenance activities should be conducted to fully control invasive species on the site and improve the
overall quality of the facility. Recommendations are as follows:
• We suggest spot herbicide applications(Task 6)and selective hand pulling/cutting/mowing(Task
8) be conducted to target cool season grasses and invasive forb species in the emergent and wet
meadow communities currently containing >60% native species coverage. Species to be
addressed during these site visits include but are not limited to: thistle spp., sweet clover,
Kentucky bluegrass, reed canary grass, hybrid cattail, willow and Queen Anne's lace. The two
species that will require the greatest effort to control are reed canary grass and cattail.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments

Oshkosh North High School Basin
The site's overall great condition minimizes maintenance requirements and the amount of effort to
accomplish them. Continued routine maintenance activities will ensure the communities remain in great
shape. Recommendations are as follows:
• A spring prescribed burn is recommended(Tasks 4&5). The burn will eliminate thatch,set-back
cool season species, assist with woody species control and blacken the earth which will spur the
growth of native species and rejuvenate the planting.
• Post-burn, we suggest spot herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) be conducted to target cool season grasses and invasive forb
species in the wet meadow and prairie communities. Species to be addressed during these site
visits include but are not limited to: thistle spp., burdock, garlic mustard, Queen Anne's lace,
reed canary grass and sweet clover.
• Cattail and purple loosestrife are the only invasive species within the emergent zone that are of
concern. Due to the low density, control should be performed carefully by hand wicking or spot
treating cattail. Purple loosestrife control should be performed by cutting and bagging seed heads
and spot treating the plants(Task 6).
• Follow-up woody vegetation control around the pond's perimeter shall be conducted(Task 14).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it

South Park Basin
To ensure invasive species do not hinder future native plantings recommended in the plan to be prepared
by NES,we recommend continued maintenance activities in 2020, similar to what was conducted in 2019
which includes:
• In the prairie/wet meadow community, we suggest timely herbicide applications (Task 6) and
selective hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb
species. Species to be addressed during these site visits include but are not limited to: thistle
spp.,burdock,purple loosestrife and reed canary grass.
• Cattail and purple loosestrife shall be removed from within the emergent zone via herbicide
applications(Task 6)and selective hand pulling/cutting/mowing(Task 8).

Southwest Industrial Park Basin A
The lack of native species establishment in the upland of this site is concerning;however;they may need
more time to establish. The dominance of cattails within the emergent zone is also problematic to the
success of planted species within that area. Recommendations are as follows:
• In the prairie community, we suggest timely herbicide applications (Task 6), mowing (Task 7)
and selective hand pulling/cutting/mowing(Task 8)to target invasive forb species. Species to be
addressed during these site visits include but are not limited to: thistle spp., burdock, Queen
Anne's lace, sweet clover, reed canary grass and wild parsnip. Due to the high coverage of
Kentucky blue grass and lack of native forb and grass species, reseeding the prairie is likely the
only way to get a native prairie established on this site. If reseeding is not a high priority, it
would still be important to control the invasive forb species, while leaving the Kentucky blue
grass for bank stabilization. If NES tried conducting a grass specific herbicide treatment to
address the Kentucky bluegrass on site, it would likely result in erosion issues as there would not
be enough vegetation to stabilize the banks.
• 2019 cattail treatments have addressed any remaining or newly sprouted plants. At this time the
emergent zone will need to be monitored to determine the need for supplemental planting based
on how well native vegetation recolonizes the treated areas. Any remaining or newly sprouted
cattail shall be treated carefully via spot treatment or hand wicking in 2020 (Task 6).
• Follow-up woody vegetation control shall be conducted(Task 14).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it
should not be continually repeated. Sometimes adaptive management needs to be implemented to

budgetary constraints will be conducted upon completion of report review by city staff(Task 1).
Southwest Industrial Park Basin B
The lack of native species establishment in the upland of this site is concerning. Improvements in the
emergent zone are clear and should only require limited efforts moving forward. Recommendations are
as follows:

• Due to the success of previous cattail treatments limited efforts of hand-wicking and or spot
treating(Task 6)shall be conducted to keep the species at bay.
• The last recommendation is that all work be documented and tracked over time to determine

Southwest Industrial Park Basin C
The positive trend in native species establishment within the prairie and the re-establishment of native
species in previously treated cattail areas is encouraging. Recommendations are as follows:
• In the prairie community, we suggest timely herbicide applications (Task 6), mowing (Task 7)
and selective hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive
forb species. Species to be addressed during these site visits include but are not limited to:thistle
spp., burdock, Queen Anne's lace, sweet clover, Kentucky bluegrass, reed canary grass and wild
parsnip. Due to the slow but sure development of native species within the prairie it is likely that
routine maintenance should keep this community on track for native species dominance. A
prescribed burn would be beneficial to this basin to further encourage the establishment of native
species but overall vegetation coverage would need to be dense enough to support the burn. The
site will need to be monitored in 2020 to determine whether or not a burn could be conducted in
2021.
• 2019 cattail treatments have addressed any remaining or newly sprouted plants. The emergent
zone has responded well to previous cattail treatments at this basin, as native species have
become well established within those areas. As long as this trend continues in the areas that were
treated for cattail in 2019, the zone should continue filling in with native species and will not
need any supplemental planting in the future. Any remaining or newly sprouted cattail shall be
treated carefully via spot treatment or hand wicking in 2020(Task 6).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments shall be made by the individual conducting work on the
site each time he or she is at the basin. If something is not working on this particular site, it

Westhaven Clubhouse Basin
The dense growth of thistle needs to be addressed in future years. Fire may be used to try to reduce the
thistle and improve native species coverage; otherwise, replanting the degraded areas is recommended.
Recommendations are as follows:
In the prairie community, we suggest timely herbicide applications (Task 6) and selective hand
