Notes to Table 6-2:
a. For lots in the RR district without City services, minimum lot area shall be 10 acres. Other
lot dimensions shall be as specified in Table 6-2. See Section 13-605.
b. The minimum building width on any side shall be at least twenty-five (25) feet, not including
any entryways or other structures that do not run the full length of the building.
c. Where at least fifty (50) percent of the front footage of any block is built up with principal
structures, the front yard setback for new structures shall be equal to the average of the
existing structures, except that any structure which is set back twenty (20) percent more
or less than the average may be discounted from the formula.
d. If townhouses are developed on parcels where only the land immediately beneath each
dwelling unit constitutes an individually-described lot and all other land constitutes common
properties, the density requirement rather than the minimum lot size shall apply to the
entire parcel.
e. Side yard setbacks shall apply to the ends of attached or semi-detached dwellings.
f. Corner properties: The side façade of a corner building adjoining a public street shall
maintain the front setback of the adjacent property fronting upon the same public street. If
no structure exists on the adjacent property, the setback shall be a minimum of one-half the
required front yard setback of the subject property’s zoning district.
g. Heights of structures may be increased with a conditional use permit as permitted in 13-
205.
h. (Amd. GO 15-14) Covered porches are permitted in the front setback compliant with the
conditional use permit requirements found in 13-205. A porch proposed for a designated
historic property or a contributing building within a historic district may be constructed
within a front and/or side yard setback provided the porch is historically appropriate or a
restoration of a significant architectural feature of the original structure.
i. Lots containing less than 60 feet of public street frontage may have a side yard reduction to
6 feet for primary buildings.
j. (Amd. GO 11-14) For single and two-family uses, 6 feet for a single story, 8 feet for a story

THINGS TO CONSIDER
13-609. Maximum impervious surface coverage. Impervious surface, including all
buildings, drives, and other paved areas, shall not cover more than forty (40) percent of any
zoning lot located in the RR District, fifty (50) percent of any zoning lot located in the R1
District, sixty (60) percent of any zoning lot in the R2 District, or seventy (70) percent of any
zoning lot in the R3 District. See the following graphic.
* FILL OUR ATTACHED “IMPERVIOUS SURFACE RATIO SHEET” IF CLOSE
TO LIMITATIONS.
Exterior Wall Bracing:
Effective April 1, 2009, the State of Wisconsin Uniform Dwelling Code implemented new wall
bracing requirements. Wall bracing had typically been accomplished by providing 4 FT sections
of wood structural panels at the corners of the building and spacing the wall panels within each
wall section at intervals not to exceed 25 FT on center. However, since it may not be possible
to meet this requirement in all cases, the State Building Code provides several alternative wall
bracing methods.
Continuously Sheathed Braced Wall Method:
This is the most frequently used method when an addition has structural sheathing (osb)
applied to the entire surface of the exterior walls. Most lumber companies and/or designers
can provide wall bracing plans for you to submit when applying for a building permit.
Permanent Weather Resistant Finish:
The exterior walls of the addition are required to be covered with a permanent weather
resistant finish. There is a misconception in the construction industry that vinyl siding is a
permanent weather resistant finish. However, the vinyl siding does not protect the osb
sheathing from getting wet, and is actually constructed with holes in it to let the water shed out
due to the fact that it is not weather resistant. Most vinyl siding manufacturers require a
weather barrier under the siding such a tar paper or house wrap. Please note that osb is not
an exterior finish material and it shall not be exposed to the elements for longer than required
during construction even if it is painted. When installing house wrap and or tarp paper please
remember to properly lap it so the water sheds from the top of the structure to the bottom.

Impervious surf
ace
means an area that
releases, as runoff, all or a large portion of the
precipitation that falls on it, except for frozen
soil. Rooftops, sidewalks, driveways and
parking lots are examples of surfaces that are
typically impervious. Surfaces in the public
right-of-way, such as a street, driveway apron
or public sidewalk, are not counted in this
calculation-only area on your property.
Impervious surface ratio
means the measure
of intensity of land use, determined by dividing
the total of all impervious surfaces on a site by
the gross area of the site.
Required
for new buildings of any kind, additions, porches, patios, driveways and walks

Respect the marks. The marks
provided by the affected utility
operators are your guide for the
duration of your project. If you
are unable to maintain the
marks during your project, or
the project will continue past
your request’s expiration date
(varies by state), please call 811
to ask for a re-mark.

Dig carefully. If you can’t avoid
digging near the marks (within
18-24 inches on all sides,
depending on state law),
consider moving your project
to another part of your yard. If
you must dig near the marks
or use machinery of any kind,
