PLAN COMMISSION STAFF REPORT DECEMBER 2, 2025
ITEM 9: Architectural Building Plan Review for New Wastewater Treatment Buildings at
233 North Campbell Road
Applicant: Stephen Matthias
Owner: City of Oshkosh
Action Requested: The applicant is requesting an architectural building plan review for a new
tertiary filtration building and UV disinfectant building.
Applicable Ordinance: State Statute 62.23(5) requires the Plan Commission review the “location
and architectural design of any public building”.
Property Location and Background Information: The subject site is an 11.42-acre property with
frontage on North Campbell Road, Dempsey Trail, Knapp Street, and Campbell Creek. The site is
used as the City’s wastewater treatment plant and includes several structures and associated
paved areas. The surrounding area consists of University athletic fields and vacant land to the
north, institutional and multi-family residential uses to the east, and a mixture of industrial and
commercial uses to the south and west. The 2040 Comprehensive Land Use Plan recommends
Community Facility use for the subject site.

The City has identified the need for two additional buildings on the existing waste water
treatment site to aid in impending treatment limits of the plant and upgrade existing treatment
operations. The first proposed building is on the northwest portion of the site adjacent to
Campbell creek and will contain new tertiary filtration units and other ancillary equipment. The
second proposed building will contain new UV disinfection treatment equipment. This building
will be constructed over an existing tank (reusing the existing foundation).

Item 9 – 233 N Campbell Rd. – Arch. Building Review
Architectural building plan review is required for the two new buildings. According to the
applicant, the new building walls will consist of tilt-up precast panels with a brick form liner
finish on the exterior. The existing buildings have block walls with brick exterior. The brick form
liner pattern of the proposed precast panels is intended to match the face brick on the existing
buildings and will be stained to match the color of the existing buildings. There will be a white
band around the top of the walls similar to some of the other buildings at the wastewater
treatment site. The applicant has noted that on past projects this approach has produced building
facades that look very similar to adjacent buildings with genuine brick and block walls.

Item 9 – 233 N Campbell Rd. – Arch. Building Review
Staff has determined that the proposed building designs will not have a negative impact on the
surrounding area as the structures will be harmonious with the intended character of the large-
scale public utility site. Although the site’s existing buildings have a brick exterior, the proposed
pre-cast panels with brick form liner will provide a consistent appearance with other existing
buildings on the site. The City’s zoning ordinance does not have design standard requirements
for institutional buildings.

Recommendation: Staff recommends approval of the architectural design of the proposed tertiary

Supplemental Information to Application
City of Oshkosh General Application (Oct 20, 2025)
Revised 11/3/2025
Narrative of the proposed request – Oshkosh WWTP Tertiary Filtration
and UV Disinfection
The City of Oshkosh (City) owns and operates a wastewater treatment plant (WWTP) which resides
on an existing 30.01-acre City-owned property at the intersection of N Campbell Creek Road and
Dempsey Trail. The treatment plant treats incoming wastewater and discharges treated effluent to
the Fox River and Campbell Creek. The City has identified the need for two additional buildings on
the existing WWTP site to aid in impending treatment limits of the plant and upgrade existing
treatment operations. The WWTP also is also upgrading their service entrance equipment and
replacing existing generators.
The first proposed building is planned for on the northwest portion of the site adjacent to Campbell
creek and will contain new tertiary filtration units and other ancillary equipment. The new building
will require routine chemical deliveries (once every 2-3 weeks) by semi-trucks that will enter the site
off of N Campbell Road. The new building will be joined to the existing north parking lot by a new
access road. The truck deliveries are expected to cause only a minimal increase in truck traffic, as
the WWTP already receives several chemical deliveries.
The second proposed building will contain new UV disinfection treatment equipment. This building
will be constructed over an existing tank (reusing the existing foundation), causing a minimal
impact to the existing landscape. The new equipment in this building will eliminate the need for the
WWTP to receive chlorine gas cylinders will reduce truck traffic to the site. Figure 1 and Figure 2
shows preliminary exterior renderings of the two new buildings with their relation to the existing site
features.
The new building walls will consist of tilt-up precast panels with a brick formliner finish on the
exterior. The brick pattern will match the face brick on the existing buildings and will get stained to
match the color of the existing buildings. There will be a white band around the top of the walls
similar to some of the other buildings at the WWTP site. On past projects, this approach has
produced building facades that look very similar to adjacent buildings with genuine brick and block
walls.
Both new buildings will include exterior HVAC equipment that is not expected to increase noise
levels above the required ordinance levels at the site. No other impacts to adjoining properties are
expected. There will be no change to the existing parking at the site. The site’s impervious surface
Page 7
ratio with the proposed improvements will increase to 35%, which is still below the allowable 60%
threshold.
The entrance service electrical equipment replacement will require the removal of two trees along
Demsey Trail. New trees will be planted in-kind on the north end of the plant. The new generator
equipment will require one additional wall louver on the front of the generator building (see
Figure 3), one additional HVAC intake hood on the roof, and an exterior generator fuel tank. The
intake hood on the roof will be similar in size to the other two existing units, which are not visible
from the road. No other impacts to adjoining properties are expected.
