The purpose of this article is to establish overlay zoning districts wherein certain additional requirements are superimposed on the underlying standard zoning districts set forth in Articles
II,
III,
IV and
V of this chapter. Each overlay district is intended to address a special land use circumstance beyond those addressed by the underlying zoning district. Special requirements include mandatory protections against natural hazards, mandatory protections of valued natural resources, special design guidelines, and measures to ensure compatibility with airport flight operations. Each overlay district is intended to implement one or more aspects of the Comprehensive Plan and to ensure compliance with federal and state requirements. Any nonconforming situation (lot, use, structure and/or site) shall adhere to the provisions of Article
IX.
A given property may lie within one or more overlay zoning districts based on its geographic location. The provisions of this article are intended to be consulted before issuance of any building permit, site plan approval, conditional use permit, zoning permit, zoning change, or land division to ensure the intended use meets all of the requirements of any applicable overlay district, in addition to the underlying standard zoning district (see Articles
II,
III,
IV and
V). For each overlay district established in this article, a definition of the resource or geographic area is provided, followed by the specific purposes of the protective regulations governing the resource or geographic location, the method of delineating the boundaries of the overlay district, and the mandatory development regulations.

[Amended 12-16-2019 by Ord. No. 2019-18]
Except where otherwise indicated in this article, the overlay
zoning districts are represented on the Official Overlay Zoning Map
adopted and from time to time amended by the Village of East Troy.
[Added 7-21-2014 by Ord. No. 2014-07]
A. Legislative findings. The Village Board makes the following legislative
findings relating to the Shoreland Overlay District:
(1) Villages are required by § 61.353, Wis. Stats., to adopt
shoreland zoning regulations meeting the minimum standards set forth
in that section by July 1, 2014.
(2) Uncontrolled use of the shorelands and pollution of the navigable
waters of the municipality would adversely affect the public health,
safety, and general welfare and impair the tax base.
B. Purpose. This section promotes the public health, safety, and welfare
and is intended to:
(1) Further the maintenance of safe and healthful conditions and prevent
and control water pollution.
(2) Protect spawning grounds, fish, and aquatic life by controlling the
removal of shoreline vegetation.
(3) Control the placement of principal buildings by establishing setbacks
from waterways.
(4) Preserve shore cover and natural beauty by:
(a) Restricting the removal of natural shoreland cover;
(b) Preventing shoreline encroachment by structures;
(c) Controlling shoreland excavation and other earthmoving activities;
and
(d) Regulating the use and placement of boathouses and other structures.
C. Boundary of district. The Shoreland Overlay District includes land located within 1,000 feet of the ordinary high-water mark of a navigable lake, pond, or flowage or within 300 feet of the ordinary high-water mark of a navigable river or stream or to the landward side of the one-hundred-year floodplain, whichever distance is greater. Any feature designated as a lake or as a stream on the Zoning Map has been determined to be navigable for the purpose of this section. The Flood Insurance Rate Maps adopted under §
510-167 of this chapter are used in determining the extent of the one-hundred-year floodplain.
D. Vegetation management within shoreline buffer zone. Woody vegetation
not located in a wetland and woody and nonwoody vegetation in a wetland
located in the shoreline buffer zone (i.e., 35 feet landward from
the ordinary high-water mark) shall not be removed, except as described
in this subsection. Vegetation listed by the Wisconsin Department
of Natural Resources as an invasive species under Ch. NR 40, Wis.
Adm. Code, may be removed, provided that the property owner reestablishes
vegetation within the shoreline buffer zone consistent with a management
plan approved by the Plan Commission. Vegetation may be removed to
create and maintain a viewing/access corridor no more than 30 feet
wide for every 100 feet of shoreline frontage.
E. Shoreline setback.
(1) Principal buildings shall be no closer than 50 feet to the ordinary
high-water mark, except that a lesser setback is allowed if all of
the following apply:
(a)
The principal building is constructed or placed on a lot or
parcel of land that is immediately adjacent on each side to a lot
or parcel of land containing a principal building.
(b)
The principal building is constructed or placed within a distance
equal to the average setback of the principal building on the adjacent
lots or 35 feet from the ordinary high-water mark, whichever distance
is greater.
(2) Accessory buildings shall comply with the setback standards for principal buildings described in this subsection, except that a boathouse may be constructed within 35 feet of the ordinary high-water mark as set forth in Subsection
F below.

Key:
|
|
---|
Lot 1
|
The principal building is existing and is more than 50 feet
from the ordinary high-water mark (OHWM).
|
Lot 2
|
The lot is vacant. Because the lots on both sides have a principal
building, setback averaging may be used, but the setback may not be
less than 35 feet. In the instance depicted above, the setback would
be calculated as follows: (50 feet plus the actual distance of the
building on Lot 3) divided by two.
|
Lot 3
|
The principal building is existing and is less than 50 feet
from the ordinary high-water mark.
|
Lot 4
|
The lot is vacant. A principal building on this lot must comply
with the fifty-foot setback requirement because setback averaging
does not apply (i.e., a principal building is only on one side).
|
Lot 5
|
The lot is vacant.
|
F. Boathouses. A boathouse constructed within the Shoreland Overlay
District shall comply with each of the following requirements:
(1) The boathouse shall be located in the viewing/access corridor as allowed in Subsection
D above.
(2) The boathouse shall be designed and constructed solely for the storage
of watercraft and related equipment; human habitation is strictly
prohibited.
(3) One boathouse is permitted on a lot as an accessory structure.
(4) The boathouse shall not be constructed where the existing slope is
more than 20%.
(5) The boathouse shall not be closer than five feet to the ordinary
high-water mark of the stream or lake on which it fronts. A boathouse
shall not be closer than five feet to a side lot line.
(6) If the boathouse is located, in whole or in part, within the Floodplain
Overlay District, all applicable standards of that district shall
apply.
(7) The boathouse shall not exceed 12 feet in height at the roof peak
above the original grade or final grade as measured on the side facing
the water body.
(8) The floor area of the boathouse shall not exceed 450 square feet.
(9) The boathouse must have an appropriate door or double-wide doors
facing the water body for the purpose of entry and exit for watercraft.
French, patio, or glass doors are prohibited.
(10)
The boathouse may contain plumbing for two sinks and one toilet,
provided that such fixtures are connected to an approved wastewater
system. Showers and/or bathtubs are prohibited.
[Amended 4-21-2014 by Ord. No. 2014-04]
A. Purpose. The residents of the Village of East Troy depend exclusively
on groundwater for a safe drinking water supply. Certain land use
practices and activities can seriously threaten or degrade groundwater
quality. The purpose of this Groundwater Protection (GP) Overlay District
is to institute land use regulations and restrictions protecting the
municipal water supply of the Village of East Troy and to promote
the public health, safety, and general welfare.
B. Authority. Statutory authority of the Village to enact these regulations
was established by the Wisconsin Legislature in 1983, Wisconsin Act
410, effective May 11, 1984, which specifically added groundwater
protection, in §§ 59.69(1) and 62.23(7)(c), Wis. Stats.,
to the statutory authorization for county and municipal planning and
zoning to protect the public health, safety, and general welfare.
C. Definition. The GP Overlay District encompasses the area of land
which contributes water to the well out to a line delineating the
five-year time of travel to the well. Time of travel delineations
must be based upon accepted hydrogeological research as outlined in
the State Wellhead Protection Program Plan for Public Water Utilities,
Appendix 2, with zoning boundaries normalized to road center lines,
railways, surface water features, public land survey section lines
(i.e., 1/2, 1/4, 1/8 or 1/16 section lines), existing property lines,
or a stated distance from the aforementioned lines.
D. Boundary. The boundary of the GP Overlay District is established
by this chapter and is depicted on the Zoning Map.
E. Groundwater Technical Review Committee. The Groundwater Technical
Review Committee shall consist of the Village Administrator, Zoning
Administrator, Village Engineer, and Director of Public Works. The
purpose of the Groundwater Technical Review Committee is to provide
objective and scientific technical review of requests for conditional
use permits and make recommendations to the Plan Commission to grant
or deny conditional use permits based upon the facts discovered in
that review, to make recommendations on any and all conditions placed
on a conditional use permit, and to give advice on matters concerning
groundwater.

(7) Commercial and industrial establishments which are connected to the
municipal sanitary sewer system.
(8) Residential land uses containing aboveground liquid propane gas tanks
for heating, provided that the tank does not exceed 1,000 gallons.
H. Prohibited uses.
(1) The method of regulation by prohibition of certain uses is employed
to provide the greatest assurance that inadvertent discharge of pollutants
into the groundwater supply will not occur, since such an event would
result in almost certain contamination of the public water supply
and costly mitigation or remediation for which liability is difficult
or impossible to establish.
(2) The prohibited uses, activities, or structures inside the GP Overlay
District include:
(b) Buried hydrocarbon, petroleum or hazardous chemical storage tanks
(e.g., identified by OSHA criteria under 40 CFR Part 370);
(d) Chemical manufacturers (Standard Industrial Classification Major
Group 28);
(f) Landfills and any other solid waste facility, except post-consumer
recycling;
(h) Manure and animal waste storage, except animal waste storage facilities
regulated by the county;

(t) Wood preserving operations; and
(u) Hazardous, toxic, or radioactive materials transfer and storage.
I. Conditional uses. Any person may request a conditional use permit for certain uses, activities and structures otherwise prohibited by Subsection
H within the GP Overlay District if these uses, activities, and structures are outside of the required separation distances listed in Subsection
F. Procedures for review and approval of conditional use permits in the GP Overlay District shall be the same as those outlined in §
510-157 of this chapter, in addition to the following requirements:
(1) An environmental assessment report prepared by a licensed environmental
engineer which details the risk to, and potential impact of, the proposed
use, activities, and structures on groundwater quality.
(2) An operational safety plan which details the operational procedures
for material processes and containment, best management practices,
stormwater runoff management and groundwater monitoring.
(3) A contingency plan which addresses, in detail, the actions that will
be taken should a contamination event caused by the proposed uses,
activities, or structures occur.
J. Nonconforming uses and structures. Existing facilities within the GP Overlay District at the time of enactment of said district that may cause or threaten to cause environmental pollution, including but not limited to those listed on the WisDNR's Inventory of Sites or Facilities Which May Cause or Threaten to Cause Environmental Pollution, Wisconsin Department of Safety and Professional Services' list of underground storage tanks, list of facilities with hazardous solid waste permits, and all other facilities which are considered a prohibited use in Subsection
H or a conditional use in Subsection
I, shall adhere to the following additional requirements:
(1) Such facilities as above which exist within the district at the time
of enactment of a district shall provide copies of all current, revised,
or new federal, state, and local facility operation approvals, permits
or certificates, operational safety plans, and ongoing environmental
monitoring results to the Village for review by the Groundwater Technical
Review Committee.
(2) Such facilities as above which exist within the district at the time
of enactment of a district shall have the responsibility of devising,
filing, and maintaining with the Village a current contingency plan
which details how they intend to respond to any emergency which may
cause or threaten to cause environmental pollution that occurs at
their facility, including notifying municipal, county, and state officials.
(3) Such facilities as above cannot engage in or employ a use, activity, or structure listed as a prohibited use in Subsection
H or a conditional use in Subsection
I which they did not engage in or employ at the time of enactment of a district and can only expand, replace, or rebuild those present uses, activities, equipment, or structures on the site or property of record associated with the facility at the time of enactment of a district and in a manner that improves the environmental and safety technologies already being utilized. No existing use, activity, or structure listed as a prohibited use or conditional use shall be expanded, replaced, or rebuilt unless a conditional use permit is granted for such expansion, replacement, or rebuilding. This subsection does not apply to normal maintenance or minor repairs.
(4) If a nonconforming use or the use of a nonconforming structure is
discontinued for 12 consecutive months, any future use of the building,
structure or property shall conform to the appropriate provisions
of this chapter.
K. Changing technology.
(1) The uses prohibited by the GP Overlay District are prohibited based
upon the combined pollution experience of many individual uses and
the technology generally employed by a particular use considered to
be of a high risk for pollution to the groundwater resource. As the
technology of other uses changes to low- or non-risk materials or
methods, upon petition from such use, after conferring with the Groundwater
Technical Review Committee or other expert opinion, and after appropriate
public notice and hearing, the Village, through appropriate procedures
and amendments to this chapter, may remove from the designated prohibited
uses list such uses that are convincingly demonstrated to no longer
pose a groundwater pollution hazard.
(2) In dealing with uses which attempt to become permissible under the
terms of this district by continuing to utilize pollutant materials
by altering their processing, storage, and/or handling, it is not
the intention to accept alternate or reduced hazards as the basis
for making a use permissible. It is the intention to continue a prohibition
on such uses until the technology of the use removes reliance upon
the pollutant materials or processes deemed to be a groundwater hazard.
L. Enforcement and penalty. Any person who violates, neglects, or refuses to comply with any of the provisions of this section shall be subject to a penalty as provided in §
510-153 of this chapter.
(1) In addition to any other remedy, the Village of East Troy may seek
an injunction or restraining order against the party alleged to have
violated the provisions herein, the cost of which shall be charged
to the defendant in such action.
(2) As a substitute for and in addition to any other action, the Village
of East Troy may commence legal action against both the person who
releases the contaminants and the owner of the facility the contaminants
were released from to recover the costs of cleanup together with the
costs of prosecution. Any person who causes the release of any contaminants
which may endanger or contaminate the municipal water supply system
associated with a GP Overlay District shall immediately cease such
discharge and immediately initiate cleanup satisfactory to the Village
of East Troy and other state and federal regulatory agencies. The
person who releases such contaminants and the person who owns the
facility the contaminants have been released from shall be jointly
and solely responsible for the cost of cleanup, consultant or other
contractor fees, including all administrative costs for oversight,
and review and documentation, including the Village employees, equipment,
and mileage.
[Amended 10-17-2016 by Ord. No. 2016-13]
