A nonconforming use may not be expanded or enlarged. A change
from one nonconforming use to another nonconforming use is not allowed.
If a nonconforming use is discontinued for a period of 12 months,
then any future use of the building and premises shall conform to
all of the requirements of this chapter and other applicable requirements
of the City Code.
Ordinary maintenance and repair to nonconforming principal structures
in the overlay district is allowed.
Nonconforming principal structures located within the ordinary
high-water setback area, bluffline setback area or slope preservation
zone may be structurally altered or reconstructed and foundations
may be replaced, improved or structurally altered if all of the following
requirements are met:
A. The lot has an area of at least 7,000 square feet.

G. Private on-site wastewater treatment systems are brought into compliance
with the requirements of Ch. SPS 383, Wis. Adm. Code, and the requirements
of the City Code.
H. The foundation of the structure may not be replaced, improved or structurally altered. Notwithstanding the definition of "reconstruction" in §
606-2 and the preceding sentence, the foundation of a nonconforming principal structure may be replaced, improved or structurally altered in conjunction with the reconstruction of the structure if the entire structure is located more than 50 feet from the ordinary high-water mark and no part of the structure lies in a slope preservation zone.
I. An erosion control plan and revegetation plan shall be submitted
to the City for approval or modification and approval prior to the
issuance of a permit for the structural alteration or reconstruction.
J. No filling and grading is allowed during alteration or reconstruction
except as minimally necessary to perform the alteration or reconstruction
in compliance with other provisions of this chapter and to bring the
site into conformity with existing sanitary, stormwater and erosion
control requirements.
K. If the nonconforming structure is located in a slope preservation
zone, it may reconstructed only if Wisconsin construction best management
practices applicable to steeper sloped areas are implemented to control
erosion. [Note: Approved best management practices for construction
site erosion control can be found on DNR website http://dnr.wi.gov/runoff/stormwater/techstds.htm.]
Nonconforming principal structures located in the ordinary high-water-mark
setback area or bluffline setback area may be expanded and the preexisting
foundation may be replaced, repaired or structurally altered in conjunction
with the expansion if all of the applicable following requirements
are met:

zone.
C. A nonconforming principal structure entirely set back more than 50
feet from the ordinary high-water mark and located wholly or partially
within 75 feet of the ordinary high-water mark may be expanded only
if the City concludes that there is no compliant building location
available elsewhere on the lot.
D. Structures entirely located more than 75 feet from the ordinary high-water
mark may be expanded regardless of whether a compliant building location
exists elsewhere on the lot.
E. For structures located wholly or partially within the ordinary high-water-mark
setback area, the total footprint of the structure may not exceed
1,500 square feet.
F. For structures located wholly or partially within the bluffline setback, but not within the ordinary high-water-mark setback area, the total footprint of the structure may not exceed 2,000 square feet and the structure shall comply with all of the requirements in §
606-12B(1) to
(5).
G. Expansion is on the side of the structure farthest from the river
or, if landward expansion is not possible, the expansion is parallel
to the ordinary high-water mark or bluffline.
H. The height of the structure complies with §
606-10.
I. The color of the structure complies with §
606-13.
J. The property owner submits a mitigation plan that complies with the requirements of §
606-39. If a permit is issued after a mitigation plan is approved, or modified and approved, by the City of Prescott zoning authority, the mitigation plan shall be incorporated into the permit and the property owner shall be required to implement the mitigation plan as a permit condition.
K. Private on-site wastewater treatment systems are brought into compliance
with the requirements of Ch. SPS 383, Wis. Adm. Code.
L. An erosion control plan and revegetation plan shall be submitted
to the City of Prescott zoning authority for approval, or modification
and approval, prior to the issuance of a permit for the expansion.
M. There will be no filling or grading conducted as part of the reconstruction
or expansion except as necessary to reconstruct or build the expansion
in compliance with other provisions of this chapter, upgrade a private
on-site wastewater treatment system, replace sewer or water laterals,
or install stormwater or erosion control measures.
Ordinary maintenance and repair of nonconforming accessory structures
in the overlay district is allowed. Nonconforming accessory structures
may not be structurally altered, reconstructed or expanded, except
that detached garages and storage sheds may be structurally altered,
reconstructed or expanded if all of the following requirements are
met, where applicable:
A. The entire detached garage or storage shed is not located in a slope
preservation zone.
B. The entire detached garage or storage shed is set back more than
75 feet from the ordinary high-water mark.
C. The detached garage or storage shed is not used for human habitation.
D. The combined footprints of all nonconforming detached accessory structures
on a lot other than existing driveways and located partially or entirely
within 75 feet of the ordinary high-water mark, in a slope preservation
zone or in a bluffline setback area may not exceed 500 square feet.
The square footage allowance for detached garages and sheds is in
addition to the square foot allowance for nonconforming principal
structures.
E. The detached garage or storage shed is built with earth-tone building
materials that are nonreflective, except that windows may be made
of ordinary window glass or nonreflective glass, but may not be made
of glass designed to reflect more light than ordinary window glass.
F. Mitigation measures are implemented and maintained that comply with the requirements of §
606-39.
G. The structure is visually inconspicuous or will be rendered so through a mitigation plan that complies with §
606-39.
Lots in the overlay district that were of record with the Pierce
County register of deeds on January 1, 1976, or on the date of the
adoption of an amendment to a City ordinance that made the lot substandard
and which do not meet the requirements of this chapter, may be allowed
as building sites if all of the following criteria are met:
A. Either the lot is held in separate ownership from abutting lands;
or the lot, by itself or in combination with an adjacent lot or lots
under common ownership in an existing subdivision has at least one
acre of net project area. Adjacent substandard lots under common ownership
may only be sold or developed as separate lots if each of the lots
has at least one acre of net project area and separately complies
with the City Code.
B. All structures that are proposed to be constructed or placed on a
substandard lot and the proposed use of the lot shall comply with
the requirements of this chapter, and all underlying City zoning and
sanitary code requirements.
Expansion, structural alteration or reconstruction of nonconforming
principal structures or nonconforming accessory structures in the
overlay district shall comply with these mitigation requirements.
Mitigation requirements shall be roughly proportional to the magnitude
of the impacts of the proposed project on scenic resources, water
quality, erosion potential and the protection of the shoreland area.
Mitigation shall include but not be limited to the following:
A. Planting of trees capable of screening the entire structure if existing
vegetation is not sufficient to render the structure visually inconspicuous.
The trees shall be native to the area, at least two inches in diameter
at breast height and planted no more than 12 feet apart parallel to
all structure(s). To allow for future growth, these trees may be planted
at different locations staggered between the structures and the river
so long as they are still no more than 12 feet apart. These trees
should be of a relatively fast-growing species such as maple and other
appropriate species.
B. The vegetation in the area within 50 feet of the ordinary high-water
mark shall be preserved or restored through planting of native vegetation.
Vegetation shall be established or maintained at densities that are
adequate to protect water quality, habitat and natural scenic beauty
of the shoreland area. Vegetation shall provide screening between
all structures and the river so as to make all nonconforming structures
visually inconspicuous while providing a limited view to the river
from the structures. A fifteen-foot wide mowed area around the structure
to protect it from wildfire is permitted.
C. Best management practices shall be followed to encourage stormwater
infiltration and to limit erosion and runoff. [Note: Approved best
management practices for construction site erosion control can be
found on DNR website http://dnr.wi.gov/runoff/stormwater/techstds.htm.]
D. A property owner shall submit an affidavit signed by all owners describing
the required mitigation plan 30 days prior to the first permit approval
hearing. The affidavit, or if the mitigation plan is modified as a
result of the permit approval hearing, a different affidavit describing
the mitigation plan approved by the City, shall be recorded with the
county register of deeds by the City Clerk within 14 days of final
permit approval. This recorded affidavit shall describe the permanent
vegetative screening, building color, erosion control and other continuing
mitigation measures that will be required of future property owners,
so as to put such future owners on notice as to mitigation measures
they will be required to sustain.
