Description:
My wife and I own the home at 425 East Davenport Street in Iowa City. For more than 100 years the sewer
line for our property has exited the back of our lot, crossed directly under the vacant lot located at 319 North
Van Buren Street, and emptied into the city sewer located in the alley which runs on the south side of the 319
Van Buren property. Because the existence of this line has never been challenged in this 100 year period we
have an easement by prescription for our sewer line.
The 319 Van Buren lot is currently vacant and has been since 2017. Prior to 2017 there was a very small
cottage which was at that time voluntarily demolished by the then owner of the property. The vacant 319 Van
Buren lot has now been sold and the city has issued a building permit for an approximate 2287 square foot
single family residence and garage to be built on the lot. The lot at 319 North Van Buren is only 35 x 80 feet
and the proposed structure has an approximate 25 x 45 foot footprint so it will interfere with my sewer line.
believe the city should not have issued the building permit for the new residence because it violates Chapter
7 of the 2021 Uniform Plumbing Code (which has been adopted by Iowa City) by not complying with the
required distance from sewer lines, by not requiring adequate underground materials and other adequate
and necessary protection and other requirements for my sewer line.

Mr Goers, here is the supplement you requested. Even though we are not required to provide this
level of detail we are doing so as a courtesy.
1. Mr. Moore is the holder of a dominant sewer line easement by virtue of his and his predecessors,
long use, and the long existence, of the sewer line that crosses the servient 319 North Van wren
Street property.
2. The 2017 voluntary demolition of the former residence at 319 North Van wren resulted in the
loss of any "grandfather" rights that the Van wren Street property may otherwise have had.
3. Iowa City has adopted the State of Iowa Plumbing Code, which is the 2021 Uniform Plumbing
Code. Under the table in Section 721.1 of the 2021 Uniform Plumbing Code two feet must be
maintained between a building and another building's sewer line.
4. The project at 319 North Van Buren is to be built directly on top of Mr Moore's sewer, meaning that
this two foot distance requirement has not been met.
5. Under Section 718.3 of the Uniform Plumbing Code any plumbing materials used under a building
must be approved for under -building use.
6. Mr Moore's sewer line is believed to be over 100 years old and is made of materials which have
not been approved for under -building use.
7. When Mr Moore attempted to discuss the location of his sewer line and possible alternatives with
the contractor he was threatened with trespass and the police were called on him.

Subject: Dave Moore appeal to Board of Appeals
Mr. Geerdes,
The City is in receipt of your appeal to the Board of Appeals dated December 20th. In it, your client stated that
the building permit should not have been issued "because it violates Chapter 7 of the 2021 Uniform Plumbing Code
(which has been adopted by Iowa City) by not complying with the required distance from sewer lines, by not requiring
adequate underground materials and other adequate and necessary protection and other requirements from my sewer
line." The City needs to know the precise nature of your client's appeal in order to be able to address it at the
hearing. Given that your client asserts the basis for his appeal is found in alleged violations of the Uniform Plumbing
Code, the City will need to know what specific provisions of the Uniform Plumbing Code your client believes have been
violated.
Until your client's appeal is supplemented with the specifics, the City considers the appeal filing
incomplete. Any allegation of a Uniform Plumbing Code violation lacking a citation to the specific Uniform Plumbing
Code provision your client believes has been violated will be considered incomplete and not addressed in the 5
appeal. Failure to cite any specific Uniform Plumbing Code provisions will result in no hearing being held. As you know,
the appeal period expired 30 days after the November 22Id issuance of the building permit, and the appeal remains
incomplete, but the City will allow your client to file a supplement if it is received by the City no later than 4:30 p.m. on
January 311, 2025. The supplement may be sent via email to Mr. Hennes or myself if that is most convenient to you.

Re: 319 N. Van Buren Street/appeal of building permit
INTRODUCTION
The owner of 425 E Davenport Street (Dave Moore) appealed the issuance of a building
permit for a new single-family home on 319 N Van Buren Street, Mr. Moore alleges the
City violated Chapter 7 of the Plumbing Code in issuing the building permit. (pages 2-4)
[- Davenport St
KA
The private sewer for 425 E Davenport Street crosses over both 323 N Van Buren
Street and 319 N Van Buren Street before entering the City's sewer main that runs
along the alley south of 319 N Van Buren. The exact location of the private sewer is not
known to City staff. City staff only knows where the private sewer enters the City's
sewer main on the alley south of 319 N Van Buren Street. (pages 25-28)
January 10, 2025
Page 2
WO
This is a civil matter between the owners of the two properties. The new construction at
319 N Van Buren Street needs to be resolved between the property owners. The City
notified all parties the presence of the private sewer for 425 E Davenport Street
crossing 319 N Van Buren Street would not prevent a building permit for 319 N Van
Buren Street from being issued. Although Attachment 1 (pages 14-15) shows the sewer
going directly from 425 E Davenport Street to Van Buren Street passing through both
323 N Van Buren Street and 319 North Van Buren Street, the exact location of the
sewer is not known to City staff. Mr. Moore claims the corner of the garage is located
over the sewer line, but the exact location of the sewer line is unknown. Additionally,
Mr. Moore does not have an easement for the use of 319 N Van Buren for his private
sewer.

Attachment 2--Building Permit and Plans (pages 17-23)

Attachment 5—Power Point (page 44)
APPEAL AND CITY'S RESPONSE TO THE APPEAL
Mr. Moore's attorney sent the City Attorney an email alleging the City made 7 errors in
issuing the building permit. (pages 2-6) Each alleged error is set forth below followed
by the City's response.
1. Alleged Error. Mr. Moore is the holder of a dominant sewer line easement by virtue
of his and his predecessors' long use, and the long existence, of the sewer line that
crosses the servient 319 North Van Buren Street property.
City response. The City is not aware of a recorded sewer easement, and at the Board of
Adjustment meeting on January 8, Mr. Moore did not state he had a recorded
easement. The City is also not aware of a Judge finding that a prescriptive easement
exists, and at the January 8 Board of Adjustment meeting, Mr. Moore did not state he
had a Court order finding a prescriptive easement. A prescriptive easement does not
exist simply because a person insists one exists. A prescriptive easement is an
unwritten easement that must be proven in Court. Only a Judge can determine if an
easement exists when one is not recorded. Last, this does not allege a violation of a
provision in Chapter 7 of the Plumbing Code.
2. Alleged Error. The 2017 voluntary demolition of the former residence at 319 North
Van Buren resulted in the loss of any "grandfather" rights that the Van Buren Street
property may otherwise have had.
City response. The City is not claiming any legacy (i.e., "grandfather") rights in the
Plumbing Code are applicable to this appeal.
3. Alleged Error. Iowa City has adopted the State of Iowa Plumbing Code, which is the
2021 Uniform Plumbing Code. Under the table in Section 721.1 of the 2021 Uniform
Plumbing Code two feet must be maintained between a building and another building's
sewer line.

City response. The City is not aware of the exact location of the private building sewer
serving 425 E Davenport Street. The City is aware of the location where a sewer enters
the City's main sewer line, but has no knowledge whether this is a straight line. See
Attachment 3, which are emails and a map from J.J. Wombacher of the City Water
Division (pages 25-28).
Sections 721.1 and 721.2 are set forth below.
721.1 Building Sever. Except as provided in Section 721.2, no building sewer shall
be located in a lot other than the lot that is the site of the building or structure served by
such sewer nor shall a building sewer be located at a point having less than the
minimum distances referenced in Table 721.1. (emphasis added)

2 See also Section 312.3
3 Drainage piping shall clear domestic water supply wells by not less than 50 feet (15240 mm). This
distance shall be permitted to be reduced to not than less than 25 feet (7620 mm) where the drainage
piping is constructed of materials approved for use within a building
4 See Section 720.0.
5 For parallel construction.
6 For crossings, approval by the Health Department or the Authority Having Jurisdiction shall be required.
721.2 Abutting Lot. Nothing contained in this code shall be construed to prohibit the use
of all or part of an abutting lot to:
(1) Provide access to connect a building or sewer to an available public sewer where proper cause
and legal easement, not in violation of other requirements, has been first established to the
satisfaction of the Authority Having Jurisdiction.
(2) Provide additional space for a building sewer where the proper cause, transfer of ownership, or
change of boundary, not in violation of other requirements, has been first established to the
satisfaction of the Authority Having Jurisdiction. The instrument recording such action shall
constitute an agreement with the Authority Having Jurisdiction and shall clearly state and show
that the areas so joined or used shall be maintained as a unit during the time they are so used.
Such an agreement shall be recorded in the office of the County Recorder as part of the
conditions of ownership of said properties, and shall be binding on heirs, successors, and assigns
to such properties. A copy of the instrument recording such proceedings shall be filed with the
Authority Having Jurisdiction.
(emphasis added)
Section 721.1 provides the sewer must be on the lot served by the sewer, which is 425
E Davenport, with one exception. The exception is the sewer may be on an abutting lot
if Section 721.2 is satisfied. 319 N Van Duren and 425 E Davenport are not abutting
properties. Because they are not abutting properties, Section 721.1 and Table 721.1
January 10, 2025
Page 4
11
are not applicable. There is no provision in the Plumbing Code regulating the situation
where the private sewer not only goes through the abutting property but also a non -
abutting property. Therefore, Section 721.1 is not violated.
Further, even in the case of an abutting lot, there must be "a legal easement ... to the
satisfaction of the Authority Having Jurisdiction" or an "agreement ... recorded in the
office of the County Recorder." Assuming for the sake of argument, the Plumbing
Code regulates construction on a non -abutting lot, the requirements for using an
abutting lot must apply, and the City has not approved an easement and there is no
recorded agreement. Moreover, only a Judge can determine if an easement exists if
there is no recorded easement.
As a result, the existing building sewer serving 425 E Davenport Street that crosses 319
N Van Buren Street is a civil issue between property owners, and the private building
sewer crossing 319 N Van Buren Street needs to be resolved between the property
owners. The City is willing to allow the existing building sewer serving 425 E Davenport
Street to remain in place, even if it is under the new home constructed at 319 N Van
Buren Street, with the understanding that a building sewer is required for 425 E
Davenport Street to meet the single-family dwelling use standards and 425 E Davenport
Street must be maintained as a functional building sewer. This can also be achieved by
relocating the building sewer service.
4. Alleged Error. The project at 319 North Van Buren is to be built directly on top of Mr
Moore's sewer, meaning that this two foot distance requirement has not been met.
City response. Mr. Moore does not allege a specific provision in Chapter 7 of the
Plumbing Code is violated. Presumably he is referencing Table 721.1.
The City is not aware of the exact location of the building sewer serving 425 E
Davenport Street. Further, the 2-foot requirement in Table 721.1 is not applicable
because the new building is not on 425 E Davenport, it is not on an abutting property,
and no Judge has determined there is an easement. See the response to Paragraph
No. 3 above.
With that said, the City is willing to allow the existing building sewer serving 425 E
Davenport Street to remain in place, even if it is under the new home constructed at 319
N Van Buren Street, with the understanding that building a sewer is required for 425 E
Davenport Street to meet the single-family dwelling use standards and 425 E Davenport
Street must be maintained as a functional building sewer. This can also be achieved by
relocating the building sewer service.
5. Alleged Error. Under Section 718.3 of the Uniform Plumbing Code any plumbing
materials used under a building must be approved for under -building use.
City response. Section 718.3 governs the installation of new sewers, not the
construction of a new building over an existing sewer. Therefore, there is no violation of
Section 718.3. Section 718.3 provides:
718.3 Protection from Damage. No building sewer or other drainage piping or part
thereof, which is constructed of materials other than those approved for use under or
within a building, shall be installed within 2 feet (610 mm) of a building or structure, or
part thereof, nor less than 1 foot (305 mm) below the surface of the ground. The
January 10, 2025
Page 5
12
provisions of this subsection include structures such as porches and steps, whether
covered or uncovered; breezeways; roofed porte cochere; roofed patios; carports;
covered walks; covered driveways; and similar structures or appurtenances. (emphasis
added)
6. Alleged Error. Mr Moore's sewer line is believed to be over 100 years old and is
made of materials which have not been approved for under -building use.
City response_. Mr. Moore does not allege a provision in Chapter 7 of the Plumbing
Code is violated. Presumably he is referencing Section 312.3. Section 312.3 regulates
the installation of new sewers, not the construction of a new building over an existing
sewer, and therefore there is no violation of this provision. Material used for the building
sewer at 425 E Davenport Street is unknown to City.
312.3 Building Sewer and Drainage Piping. No building sewer or other drainage
piping or part thereof, constructed of materials other than those approved for use under
or within a building shall be installed under or within 2 feet (610 mm) of a building or
structure, or less than 1 foot (305 mm) below the surface of the ground. (emphasis
added)
7. Alleged Error, When Mr Moore attempted to discuss the location of his sewer line
and possible alternatives with the contractor he was threatened with trespass and the
police were called on him.
City response. This is not a violation of the Plumbing Code and irrelevant to this appeal.
CONCLUSION
The City did not violate any provision in the Plumbing Code in issuing the building
permit.

As you may be aware the vacant lot at 319 N. Van Buren Street is for sale. Prospective buyers
have brought to the City's attention that the sanitary sewer service for your property at 425 E
Davenport Street runs south through the rear yard of 323 N Van Buren Street and 319 N Van
Buren Street. The image below was provided by the Iowa City Wastewater Division and shows
the approximate locations of the sanitary sewer services for the referenced properties. As far as
we are aware at this time, the sewer service line from your property is not a city owned sanitary
service line nor main line and is not located in an easement between private property owners.

As the owners of 425 E Davenport Street, it is your responsibility to provide a sanitary sewer
service connection from the dwelling on the property to the to the City's main sewer line. It is
not the responsibility of the City.
The City is advising the owner or potential buyers of 319 N Van Buren Street to consult a private
attorney regarding the matter of the private sanitary sewer service across the property. We
would advise you to do the same.
The presence of the private sanitary sewer service for 425 E Davenport Street crossing 319 N
Van Buren Street will not prevent a building permit for 319 N Van Buren Street being issued.
Please reach out to me if you have any questions that I can answer on this issue

Thanks JJ,
Remind me of the depth of the sewer main in the alley. Also, the active service that is at 111' is on the side of the main
and not on the top, correct?

Subject: RE: 319 Van Buren
All we know for certain is that there is an active service 111' east of the manhole in the alley between Gilbert St and Van
Buren St. We are making an educated guess that this is the service for 425 Davenport. I do NOT know where the service
comes out of 425 or the path it takes to get to the city main. If this information is needed, it is the property owners
responsibility to have their service televised and located by a private contractor.
If there is anything else I can do to help let me know!
Thanks!

JJ,
When we talked did I understand you correctly to say you know where the private sewer for 425 E Davenport connects
to the city main and you know where it comes out of the house but the route between the two place is unknown? Or is
it that you know where it connects to the city main and not where it comes out of the house at 425 E Davenport?
If you have a minute would you give me a call?

Subject: 319 Van Buren
Team,
From a video inspection on 4/4/2023 1 have noted these active services that would possibly serve houses on the north
side of sewer line 016-75_016-70 (line in the alley south of Davenport between Gilbert and Van Buren). The video was
recorded with the flow from manhole 016-75 to manhole 016-70 (west to east).
59' downstream 9 o'clock
111' downstream 9 o'clock
125' downstream 12 o'clock (picture attached, appears to turn back to the south but unable to verify)
180' downstream 9 o'clock
186' downstream 9 o'clock
The service at 125' was not on our map, I will include a pdf of its general location as well. (indicated by a dark green line
with an arrow. (This indicates where the connection to our main is and does not represent location or direction of the
actual service line)
if you would like to view the video in its entirety I am more than willing to drop it in a file somewhere, if file path is
provided. Unfortunately it is just a little to large to send through email.
If there is anything else I can help with, I am more than happy to assist!
Thanks!
