ORDINANCE 93-01
SHORE LAND MANAGEMENT ORDINANCE
SUMMARY OF REGULATIONS:
The Prior Lake City Council adopted a Shore land Management Ordinance for the City of Prior Lake on
March 1, 1993 subject to approval from the Minnesota Department of Natural Resources. The City
formally submitted the Shore land Ordinance to MDNR on March 3, 1993. The Minnesota Legislature
passed Chapter 248, Laws of Minnesota 1995 which requires that an agency must, for any written requests
submitted after July 1, 1995, approve or deny a written request related to zoning within 60 days of receipt
of a complete application. Failure of the agency to act within the 60 day period is deemed by the Law to
be approval of the request. The City of Prior Lake again formally transmitted a copy of the approved
Shoreland Management Ordinance to the MNDNR on July 18, 1995 for its review and acceptance. The
deadline for response by MNDNR passed with no comment related to the Shore land Management
Ordinance. Therefore, by operation of Chapter 248, Article 18, Laws of Minnesota 1995, the MDNR has
approved anrj accepted the Shoreland Management Ordinance. On November 6, 1995 the City Council of
Prior Lake adopted Resolution 95-112 which ratified and reaffirmed passage and approval of the Shore land
Management Ordinance and ordered publication of the Ordinance which shall become effective upon its'
publication date.
The following paragraphs summarize the Shore land Management Ordinance. Tile entire Ordinance is
available for review and or purchase from the Prior Lake Planning Department located at Prior Lake

GENERAL PROVISIONS:
The City of Prior Lake has been authorized by State Law to adopt and administer Shore land Management
regulations consistent with Minnesota Statutes, Chapter 103, Minnesota Regulations, Parts 6120.2500 _
6120.3900, and the planning and zoning enabling legislation in Minnesota Statutes, Chapter 462. The
Ordinance will regulate all lands located within 1,000' of a designated public lake and 300' of a designated
river or tributary. The lands to which the Ordinance applies are indicated on the Official Zoning Map of
the City of Prior Lake.
The uncontrolled use of shore lands of the City of Prior lake affects the public health, safety and general
welfare not only by contributing to pollution of public waters, but also by impairing the local tax base. The
legislature of Minnesota has delegated responsibility to municipalities of the State to regulate the
subdivision, use and development of the shore lands of public waters and thus preserve and enhance the
quality of surface waters, preserve the economic and natural environmental values of shorelands, and
provide for the wise utilization waters and related land resources.
DESIGNATION OF TYPES OF LAND USE:
The Ordinance regulates the shore lands of II lakes and two tributary streams in Prior Lake, including
Prior Lake and Spring Lake. The Shoreland Management Zone is an overlay zoning district which applies
specified regulations to properties located in the zone. All permitted and conditional uses allowed by the
underling zoning district are permitted. The Ordinance specifically regulates Substandard Uses.
Substandard Uses are those uses of shorelands existing prior to the date of enactment of the Ordinance
which are permitted within the Zoning District but do not meet the minimum lot area, setback or other
dimensional requirements. Structural alterations which substantially increase a substandard use or structure
may not be allowed.

Minnesota Regulations, Parts 6120.2500 - 6120.3900, and the planning and
zoning enabling legislation in Minnesota Statutes, Chapter 462.
Policy: The uncontrolled use of shorelands of the City of Prior Lake affects the
public health, safety and general welfare not only by contributing to pollution of
public waters, but also by impairing the local tax base. Therefore, it is in the best
interests of the public health, safety and welfare to provide for the wise
development of shorelands of public waters. The Legislature of Minnesota has
delegated responsibility to the municipalities of the State to regulate the
subdivision, use and development of the shorelands of public waters and thus
preserve and enhance the quality of surface waters, preserve the economic and
natural environmental values of shorelands, and provide for the wise utilization of
waters and related land resources. This responsibility is hereby recognized by
the City of Prior Lake.

subdivision or by all purchasers of non-riparian lots in the
subdivision who are provided riparian access rights on the access
lot; and
d) Covenants or other equally effective legal instruments must be
developed that specify which lot owners have authority to use the
access lot and what activities are allowed. The activities may
include watercraft launching, loading, storage, beaching, mooring,
or docking. They must also include other outdoor recreational
activities that do not significantly conflict with general public use of
the public water or the enjoyment of normal property rights by
adjacent property owners. Examples of the non-significant conflict
activities include swimming, sunbathing, or picnicking. The
- 17-
covenants must limit the total number of vehicles allowed to be
parked and the total number of watercraft allowed to be
continuously moored, docked, or stored over water, and must
require centralization of all common facilities and activities in the
most suitable locations on the lot to minimize topographic and
vegetation alterations. They must also require all parking areas,
storage buildings, and other facilities to be screened by vegetation
or topography as much as practical from view from the public
water, assuming Summer, leaf on conditions.
D. Placement, Design, and Height of Structures:
1. Setback requirements from the ordinary high water mark shall not apply
to piers and docks. Location of piers and docks shall be controlled by
applicable state and local regulations.
2. On undeveloped shoreland lots that have two (2) adjacent lots with
existing principle structures on both such adjacent lots, any new
residential structure may be set back from the average setback of the
adjacent structures from the ordinary high water mark or fifty (50) feet,
whichever is greater, provided all other provisions of the Shoreland
District are complied with. In no instance shall a principal structure be
located in a shore impact zone or a bluff impact zone.
3. High Water Elevations. Structures must be placed in accordance with
any floodplain regulations applicable to the site. Where these controls do
not exist, the elevation to which the lowest floor, including basement, is
placed must be determined as follows:
a) For lakes, by placing the lowest floor at a level at least three (3)
feet above the highest known water level, or three (3) feet above
the ordinary high water level, whichever is higher;
b) For rivers and streams, by placing the lowest floor at least three
(3) feet above the flood of record, if data are available. If data are
not available, by placing the lowest floor at least three (3) feet
above the ordinary high water level, or by conducting a technical
evaluation to determine effects of proposed construction upon
flood stages and flood flows and to establish a flood protection
elevation. Under all three approaches, technical evaluations must
be done by a qualified engineer or hydrologist consistent with
Parts 6120.5000 to 6120.6200 governing the management of
floodplain areas. If more than one approach is used, the highest
flood protection elevation determined must be used for placing
structures and other facilities, and
c) Water-oriented accessory structures may have the lowest floor
placed lower than the elevation determined in this item if the
structure is constructed of flood-resistant materials to the
elevation, electrical and mechanical equipment is placed above
the elevation and, if long duration flooding is anticipated, the
structure is built to withstand ice action and wind-driven waves
and debris.
4. One (1) water-oriented accessory structure may be allowed per lot on
General Development (GD) lakes that have municipal sewer and water,
provided a building permit is obtained form the City of Prior Lake and the
following criteria are met:
- 18 -
-
a) The lot contains a slope equal to or greater than twenty (20)
percent measured from the front of the principal structure to the
ordinary high water mark; and
b) The structure must be one (1) story in height and cannot occupy
an area greater than one hundred twenty (120) square feet and
the maximum height of the structure must not exceed ten (10) feet
including the roof; and
c) The structure shall be located in the most visually inconspicuous
portion of the lot, as viewed from the surface of the lake, assuming
Summer, leaf-on conditions. The minimum setback requirement
must be at least ten (10) feet from the ordinary high water mark
and meet the other applicable side yard setbacks. The setbacks
shall be verified by a certificate of survey prepared by a registered
surveyor; and
d) The structure must not be designed or used for human habitation
and must not contain water supply or sewage treatment facilities.
However, the structure may contain electrical and mechanical
systems; and
e) The structure must be constructed of treated wood and/or block
that is compatible with the principal structure and designed to
reduce visibility as viewed from public waters and adjacent
shorelands by vegetation, topography, increased setbacks or
color, assuming Summer, leaf-on conditions; and
f) If the proposed structure will be located below the regulatory
floodplain elevation, the structure must be built compliant with
applicable flood-proofing requirements of the Building Code and
Prior Lake Floodplain Ordinance; and
g) Trees that are four (4) inches in caliper or larger should not be
removed for the erection of a water-oriented accessory structure.
If removal is necessary, replacement with like trees must be made
with the approval of the Building Official. Erosion control
measures, as required by the Building Official, must be
implemented and all disturbed vegetation replaced with sod or
suitable landscaping materials.
h) The structure shall be attached to a permanent foundation so as
to be immovable from its approved location.
5. Stairways, Lifts, and Landings. Stairways and lifts are the preferred
alternative to major topographic alterations for achieving access up and
down bluffs and steep slopes to shore areas. Stairways and lifts must
meet the following design requirements.
a) Stairways and lifts must not exceed four (4) feet in width on
residential lots. Wider stairways may be used for commercial
properties, public open space recreational properties, and planned
unit developments;
b) Landings for stairways and lifts on residential lots must not exceed
thirty-two (32) square feet in area. Landings larger than thirty-two
- 19 -
square feet may be used for commercial properties, public open
space recreational properties, and planned unit developments.
The required lakeshore setback for landings shall be ten (10) feet,
measured from the ordinary high water mark of the public water.
Landings shall not project into any required side yard setback.
c) Canopies or roofs are not allowed on stairways, lifts, or landings;
d) Stairways, lifts, and landings may be either constructed above the
ground on posts or pilings, or placed into the ground, provided
they are designed and built in a manner that ensures control of
soil erosion:
e) Stairways, lifts and landings must be located in the most visually
inconspicuous portions of lots, as viewed form the surface of the
public water assuming Summer, leaf on conditions, whenever
practical; and
f) Facilities such as ramps, lifts, or mobility paths for physically
handicapped persons are also allowed for achieving access to
shore areas, provided that the dimensional and performance
standards of sub-items (1) to (5) are complied with in addition to
the requirements of Minnesota Regulations, Chapter 1340.
6. Significant Historic Sites. No structure may be placed on a significant
historic site in a manner that affects the values of the site unless
adequate information about the site has been removed and documented
in a public repository.
7. Steep Slopes. The City Engineer must evaluate possible soil erosion
impacts and development visibility form public waters before issuing a
permit for construction of sewage treatment systems, roads, driveways,
structures, or other improvements on steep slopes. When determined
necessary, conditions must be attached to issued permits to prevent
erosion and to preserve existing vegetation screening of structures,
vehicles, and other facilities as viewed form the surface of public waters,
assuming Summer, leaf on vegetation.
8. Height of Structures. All structures in residential districts, except
churches and non-residential agricultural structures, must not exceed
thirty-five (35) feet in height.

subject to the following conditions:
a) Permitted uses on islands are limited to seasonal cabins, public
parks, and open space. Year round residences are not permitted.
Recreational facilities, such as a pavilion or picnic facilities for a
homeowners association, may also be permitted by conditional
use permit as set forth in Section 9.7 of this Ordinance.
b) Any structure built on an island must contain an enclosed septic
system or incinerator toilet facilities.
c) An application for building permit or variance must include a
signed lease arrangement that indicates that the owner has two,
on land, parking spaces for vehicles. Parking vehicles on public
streets, while occupying a seasonal structure on the island, is not
permitted. In addition, the owner is required to provide proof of
residency, at some location other than the island, at the time of
building permit application.
d) The minimum lot size for all islands without municipal sewer and

vegetation shall be restored insofar as feasible immediately after
any construction project is completed to retard surface runoff and
soil erosion.
h) Any removal of vegetation in conjunction with any construction
project shall require a restoration plan to be submitted and
reviewed by the City to ensure that natural vegetation is retained
insofar as possible to screen seasonal structures and other
buildings on site.
i) The lowest floor elevation of the structure including basement and
crawl space must meet the City's Floodplain Management
Ordinance requirements or provisions for locating the low flood
elevation as described in Section 9.3.D.3 of this Ordinance.
9.4 SHORELAND ALTERATIONS: Alterations of vegetation and topography will
be regulated to prevent erosion into public waters, fix nutrients, preserve shoreland
- 21 -
aesthetics, preserve historic values, prevent bank slumping, and protect fish and wildlife
habitat.
A. Vegetation Alterations:
1. Vegetation alteration necessary for the construction of structures and
sewage treatment systems and the construction of roads and parking
areas regulated by this Ordinance are exempt from the vegetation
alteration standards that follow.
2. Removal or alteration of vegetation, except for agricultural and forest
management uses as regulated by this Ordinance is allowed subject to
the following standards:
a) Intensive vegetation clearing within the shore and bluff impact
zones and on steep slopes is not allowed. Intensive vegetation
clearing for forest land conversion to another use outside of these
areas is allowable as a conditional use if an erosion control and
sedimentation plan is developed and approved by the soil and
water conservation district in which the property is located.
b) In shore and bluff impact zones and on steep slopes, limited
clearing of trees and shrubs and cutting, pruning, and trimming of
trees is allowed to provide a view to the water from the principal
dwelling site and to accommodate the placement of stairways and
landings, picnic areas, access paths, beach and watercraft
access, and permitted water oriented accessory structures of
facilities, provided that:
1. The screening of structures, vehicles, or other facilities as
viewed from the water, assuming Summer, leaf on
conditions, is not substantially reduced;
2. Along rivers, existing shading of water surfaces is
preserved; and
3. The above provisions are not applicable to the removal of
trees, limbs, or branches that are dead, diseased, or pose
safety hazards.
B. Topographic Alterations/Grading and Filling:
1. Grading and filling and excavations necessary for the construction of
structures, sewage treatment systems and driveways under validly issued
construction permits for these facilities do not require the issuance of a
separate grading and filling permit. However, the grading and filling
standards in this section must be incorporated into the issuance of
permits for construction of structures, sewage treatment systems, and
driveways.
2. Public roads and parking areas are regulated by Section 9.4C of this
Ordinance.
3. Notwithstanding items 1 and 2 above, a grading and filling permit will be
required for:
- 22-
-
a} The movement of more than ten (10) cubic yards of material on
steep slopes or within shore or bluff impact zones; and
b} The movement of more than fifty (50) cubic yards of material
outside of steep slopes and shore and bluff impact zones.
4. The following considerations and conditions must be adhered to during
the issuance of construction permits, grading and filling permits,
conditional use permits, variances and subdivision approvals:
a} Grading or filling in any type 2, 3, 4, 5, 6, 7, or 8 wetland, as
defined in the United States Fish and Wildlife Service Circulation
No. 39 (1971 Edition), must be evaluated to determine how
extensively the proposed activity would affect the following
functional qualities of the wetland*:
1. Sediment and pollutant trapping and retention;
2. Storage of surface runoff to prevent or reduce flood
damage;
3. Fish and wildlife habitat;
4. Recreational use;
5. Shoreline or bank stabilization; and
6. Noteworthiness, including special qualities such as historic
significance, critical habitat for endangered plants and
animals, or others.
* This evaluation must also include a determination of
whether the wetland alteration being proposed requires permits,
reviews, or approvals by other local, state, or federal agencies
such as a watershed district, the Minnesota Department of Natural
Resources, or the United States Army Corps of Engineers. The
applicant will be so advised.
b} Alterations must be designed and conducted in a manner that
ensures only the smallest amount of bare ground is exposed for
the shortest time possible;
c} Mulches or similar materials must be used, where necessary, for
temporary bare soil coverage, and a permanent vegetation cover
must be established as soon as possible.
d} Methods to minimize soil erosion and to trap sediments before
they reach any surface water feature must be used;
e} Altered areas must be stabilized to acceptable erosion control
standards consistent with the field office technical guides of the
local soil and water conservation districts and the United States
Soil Conservation Service;
f} Fill or excavated material must not be placed in a manner that
creates an unstable slope;
.23.
g) Plans to place fill or excavated material on steep slopes must be
reviewed by qualified professionals for continued slope stability
and must not create finished slopes of thirty (30) percent or
greater;
h) Fill or excavated material must not be placed in bluff impact
zones;
i) Any alterations below the ordinary high water level of public
waters must first be authorized by the Commissioner under
Minnesota Statutes, Section 1 03G.241 ;
j) Alterations of topography must only be allowed if they are
accessory to permitted or conditional uses and do not adversely
affect adjacent or nearby properties; and
k) Placement of natural rock riprap, including associated grading of
the shoreline and placement of a filter blanket, is permitted if the
finished slope does not exceed three (3) feet horizontal to one foot
vertical, the landward extent of the riprap is within ten (10) feet of
the ordinary high water level, and the height of the riprap above
the ordinary high water level does not exceed three (3) feet.
C. Placement and Design of Roads, Driveways and Parking Areas:
1. Public and private roads and parking areas must be designed to take
advantage of natural vegetation and topography to achieve maximum
screening from view from public waters. Documentation must be
provided by a qualified individual that all roads and parking areas are
designed and constructed to minimize and control erosion to public
waters consistent with the field office technical guides of the local soil and
water conservation district, or other applicable technical materials.
2. Roads, driveways, and parking areas must meet shoreland setbacks and
must not be placed within bluff and shore impact zones, when other
reasonable and feasible placement alteration exist. If no alternatives
exist, they may be placed within these areas, and must be designed to
minimize adverse impacts.
3. Public and private watercraft access ramps, approach roads, and
access-related parking areas may be placed within shore impact zones
provided the vegetative screening and erosion control conditions of this
sub-part are met. For private facilities, the grading and filling provisions
of Section 9.4.B of this Ordinance must be met.
D. Storm Water Management:
1. When possible, existing natural drainageways, wetlands, and vegetated
soil surfaces must be used to convey, store, filter, and retain storm water
runoff before discharge to public waters.
2. Development must be planned and conducted in a manner that will
minimize the extent of disturbed areas, runoff velocities, erosion potential,
and reduce and delay runoff volumes. Disturbed areas must be stabilized
and protected as soon as possible in accordance with Best Management
Practices. Facilities or methods shall be used to retain sediment on the
site.
- 24-
11
-
3. When development density, topographic features, and soil and vegetation
conditions are not sufficient to adequately handle storm water runoff using
natural features and vegetation, various types of constructed facilities
such diversions, settling basins, skimming devices, dikes, waterways, and
ponds may be used. Preference must be given to designs using surface
drainage, vegetation, and infiltration rather than buried pipes and
man-made materials and facilities.
4. When constructed facilities are used for storm water management,
documentation must be provided by a qualified individual that they are
designed and installed consistent with the field office technical guide of
the local soil and water conservation districts.
5. New constructed storm water outfalls to public waters must provide for
filtering or settling of suspended solids and skimming of surface debris
beforejischarge.

adopted by reference and declared to be a part of this Ordinance.
3. On-site sewage treatment systems must be set back from the ordinary
high water level in accordance with the setbacks contained in Section
9.3.A.1 of this Ordinance.
4. All proposed sites for individual sewage treatment systems shall be
evaluated in accordance with the criteria in sub-items a) - d). If the
determination of a site's suitability cannot be made with publicly available,
existing information, it shall then be the responsibility of the applicant to
provide sufficient soil borings and percolation tests from on-site field
investigations.
Evaluation Criteria:
a) Depth to the highest known or calculated ground water table or
bedrock;
b) Soil conditions, properties, and permeability;
c) Slope;

6. An existing treatment system not meeting the requirements of this
Ordinance must be upgraded, at a minimum, at any time a building or
zoning permit or variance of any type is required for any improvement on,
or use of, the property. For the purposes of this provision, a sewage
treatment system shall not be considered non-conforming if the only
deficiency is the sewage treatment system's improper setback from the
ordinary high water level.
7. The City of Prior Lake has by formal resolution notified the Commissioner
of its program to identify non-conforming sewage treatment systems. The
City of Prior Lake will require upgrading or replacement of any
non-conforming system identified by this program within two (2) years, as
described in Section 9.6.B.6 of this Ordinance. Sewage systems installed
according to all applicable local shoreland management standards
adopted under Minnesota Statutes, Section 105.485, in effect at the time
of installation may be considered as conforming unless they are
determined to be failing, except that systems using cesspools, leaching
pits, seepage pits, or other deep disposal methods, or systems with less
soil treatment area separation above ground water than required by the
Minnesota Pollution Control Agency's Chapter 7080 for design of on-site
sewage treatment systems, shall be considered non-conforming.
- 27-
9.7 CONDITIONAL USES: Conditional uses allowable within shoreland areas shall
be subject to the review and approval procedures, and criteria and conditions for review
of conditional uses established in Section 9.4 B4 of this Ordinance.
The following additional evaluation criteria and conditions apply within shoreland areas:
A. Evaluation Criteria: A thorough evaluation of the waterbody and the topographic,
vegetation, and soils conditions on the site must be made to ensure:
1. The prevention of soil erosion or other possible pollution of public waters,
both during and after construction;
2. The visibility of structures and other facilities as viewed from public waters
is limited;
3. The site is adequate for water supply and on-site sewage treatment; and
4. The types, uses, and numbers of watercraft that the project will generate
are compatible in relation to the suitability of public waters to safely
accommodate these watercraft.
B. Conditions Attached to Conditional Use Permits: The City Council, upon
consideration of the criteria listed above and the purposes of this Ordinance,
shall attach such conditions to the issuance of the conditional use permits as it
deems necessary to fulfill the purposes of this Ordinance. Such conditions may
include, but are not limited to, the following:
1. Increased setbacks from the ordinary high water level;
9.8
A.
2. Limitations on the natural vegetation to be removed or the requirement
that additional vegetation be planted; and
3. Special provisions for the location, design, and use of structures, sewage
treatment systems, watercraft launching and docking areas, and vehicle
parking areas.
VARIANCES:
B.
Variances may only be granted in accordance with Minnesota Statutes, Chapter
462, as applicable. A variance may not circumvent the general purposes and
intent of this Ordinance. No variance may be granted that would allow any use
that is prohibited in the zoning district in which the subject property is located.
Conditions may be imposed in the granting of a variance to ensure compliance
and to protect adjacent properties and the public interest. In considering a
variance request, the Board of Adjustment must also consider whether the
property owner has reasonable use of the land without the variance, whether the
property is used seasonally or year-round, whether the variance is being
requested solely on the basis of economic considerations, and the characteristics
of development on adjacent properties.
The Board of Adjustment shall hear and decide requests for variances in
accordance with the rules that it has adopted for the conduct of business. When
a variance is approved after the Department of Natural Resources has formally
recommended denial in the hearing record, the notification of the approved
variance required in Section 9.10 shall also include the Board of Adjustment's
summary of the public record/testimony and the findings of facts and conclusions
which supported the issuance of the variance.
- 28-
9.9
C.
C.
For existing developments, the application for variance must clearly demonstrate
whether a conforming sewage treatment system is present for the intended use
of the property. The variance, if issued, must require reconstruction of a
non-conforming sewage treatment system.
SUBDIVISION/PLATTING PROVISIONS:
A.
Land Suitability: Each lot created through subdivision, including planned unit
developments authorized under Section 9.9 of this Ordinance, must be suitable
in its natural state for the proposed use with minimal alteration. Suitability
analysis by the local unit of government shall consider susceptibility to flooding,
existence of wetlands, soil and rock formations with severe limitations for
development, severe erosion potential, steep topography, inadequate water
supply or sewage treatment capabilities, near-shore aquatic conditions
unsuitable for water-based recreation, important fish and wildlife habitat,
presence of significant historic sites, or any other feature of the natural land likely
to be harmful to the health, safety, or welfare of future residents of the proposed
subdivision.
B.
Consistency with Other Controls: Subdivisions must conform to all official
controls within the Prior Lake Subdivision Ordinance. A subdivision will not be
approved where a later variance from one or more standards in official controls
would be needed to use the lots for their intended purpose. In areas not served
by publicly owned sewer and water systems, a subdivision will not be approved
unless domestic water supply is available and a sewage treatment system
consistent with Section 9.6 can be provided for every lot. Each lot shall meet the
minimum lot size and dimensional requirements of Section 9.3, including at least
a minimum contiguous lawn area, that is free of limiting factors sufficient for the
construction of two standard soil treatment systems. Lots that would require use
of holding tanks must not be approved.
Information Requirements: Sufficient information must be submitted by the
applicant for the community to make a determination of land suitability. The
information shall include at least the following:
1. Topographic contours at ten (10) foot intervals or less from United States
Geological Survey maps or more accurate sources, showing limiting size
characteristics;
2. The surface water features required in Minnesota Statutes, Section
505.02, Subdivision 1, to be shown on plats, obtained from United States
Geological Survey quadrangle topographic maps or more accurate
sources;
3. Adequate soils information to determine suitability for building and on-site
sewage treatment capabilities for every lot from the most current existing
sources or from field investigations such as soil borings, percolation tests,
or other methods;
4. Information regarding adequacy of domestic water supply; extent of
anticipated vegetation and topographic alterations; near-shore aquatic
conditions, including depths, types of bottom sediments, and aquatic
vegetation; and proposed methods for controlling storm water runoff and
erosion, both during and after construction activities;

5. Location of 100 year floodplain areas and floodway districts from existing
adopted maps or data; and
6. A line or contour representing the ordinary high water level, the "toe" and
the "top" of the bluffs, and the minimum building setback distances from
the top of the bluff and the lake or stream.
D.
Dedications: When a land or easement dedication is a condition of subdivision
approval, the approval must provide easements over natural drainage or ponding
areas for management of storm water and significant wetlands.
E.
Platting: All subdivisions that create five or more lots or parcels that are ten (10)
acres or less in size shall be processed as a plat in accordance with Minnesota
Statutes, Chapter 505. No permit for construction of buildings or sewage
treatment systems shall be issued for lots created after these official controls
were enacted unless the lot was approved as part of a formal subdivision.
Controlled Access or Recreational Lots: Lots intended as controlled accesses to
public waters or for recreational use areas for use by non-riparian lots within a
subdivision must meet or exceed the sizing criteria in Section 9.3 of this
Ordinance.
F.
NOTIFICATIONS TO THE DEPARTMENT OF NATURAL RESOURCES:
A.
Copies of all notices of any public hearings to consider variances, amendments,
or conditional uses under local shoreland management controls must be sent to
the Commissioner or the Commissioners designated representative and
postmarked at least ten (10) days before the hearings. Notices of hearings to
consider proposed subdivisions/plats must include copies of the subdivision/plat.

PLANNED UNIT DEVELOPMENTS (PUDs):
A.
Types of PUDs Permissible: Planned unit developments (PUDs) are allowed for
new projects on undeveloped land, redevelopment of previously built sites, or
conversions of existing buildings and land. The land use districts in which they
are an allowable use are identified in the land use district descriptions in
Subdivision 9.2.8.1 of this Ordinance and the official zoning map.
8.
Application for a PUD: The applicant for a PUD must submit the following
documents prior to final action being taken on the application request:
1. A site plan and/or plat for the project showing locations of property
boundaries, surface water features, existing and proposed structures and
other facilities, land alterations, sewage treatment and water supply
systems (where public systems will not be provided), and topographic
contours at two (2) foot intervals or less. When a PUD is a combined
commercial and residential development, the site plan and/or plat must
indicate and distinguish which buildings and portions of the project are
residential, commercial, or a combination of the two.
2. A property owners association agreement (for residential PUDs) with
mandatory membership, and all in accordance with the requirements of
Section 9.11.F of this Ordinance.
3. Deed restrictions, covenants, permanent easements or other instruments
that: 1) properly address future vegetative and topographic alterations,
construction of additional buildings, beaching of watercraft, and
construction of commercial buildings in residential PUDs and 2) ensure
the long term preservation and maintenance of open space in accordance
with the criteria and analysis specified in Section 9.11.F of this Ordinance.
4. When necessary, a master plan/drawing describing the project and the
floor plan for all commercial structures to be occupied.
5. Those additional documents as requested by the Zoning Administrator
that are necessary to explain how the PUD will be designed and will
function.
C. Site "Suitable Area" Evaluations: Proposed new or expansions to existing
planned unit developments must be evaluated using the following procedures
and standards to determine the suitable area for the dwelling unit/dwelling site
density evaluation in Section 9.11.F of this Ordinance.
1. The project parcel must be divided into tiers by locating one or more lines
approximately parallel to a line that identifies the ordinary high water level
at the following intervals, proceeding landward.
- 31 -
Shoreland Tier Dimensions
Unsewered Sewered
(feet) (feet)
General Development Lakes-
First Tier 200 200
General Development Lakes-
Second Tier 267 200
Recreational Development
Lakes 267 267
Natural Environment Lakes 400 320
All River Classes 300 300
2. The suitable area within each tier is next calculated by excluding from the
tier area all wetlands, bluffs, or land below the ordinary high water level of
public waters. This suitable area and the proposed project are then
subject to either the residential or commercial planned unit development
density evaluation steps to arrive at an allowable number of dwelling units
or sites.
D. Residential and Commercial PUD Density Evaluation: The procedures for
determining the "base" density of a PUD and density increase multipliers are
outlined as follows. Allowable densities may be transferred from any tier to any
other tier further from the waterbody, but must not be transferred to any other tier
closer.
1. Residential PUD "Base" Density Evaluation.
a) The suitable area within each tier is divided by the single
residential lot size standard for lakes or, for rivers, the single
residential lot width standard times the tier depth, unless the local
unit of government has specified an alternative minimum lot size
for rivers which shall then be used to yield a base density of
dwelling units or sites for each tier. Proposed locations and
numbers of dwelling units or sites for the residential planned until
developments are then compared with the tier, density, and
suitability analysis herein and the design criteria in Section 9.11.F
of this Ordinance.
2. Commercial PUD "Base" Density Evaluation.
a) Determine the average inside living area size of dwelling units or
sites within each tier, including both existing and proposed units
and sites. Computation of inside living area sizes need not
include decks, patios, stops, steps, garages, or porches and
basements, unless they are habitable space.
b) Select the appropriate floor area ratio from the following table.

*For average unit floor areas less than shown, use the floor area ratios listed for 200 square
feet. For areas greater than shown, use the ratios listed for 1,500 square feet. For recreational
camping areas, use the ratios listed at 400 square feet. Manufactured home sites in
recreational camping areas shall use a ratio equal to the size of the manufactured home, or if
unknown, the ratio listed for 1,000 square feet.
c) Multiply the suitable area within each tier by the floor area ratio to
yield total floor area for each tier allowed to be used for dwelling
units or sites.
d) Divide the total floor area by tier computed in Item C above by the
average inside living area size determined in Item A above. This
yields a base number of dwelling units and sites for each tier.
e) Proposed locations and numbers of dwelling units or sites for the
commercial planned unit development are then compared with the
tier, density and suitability analysis herein and the design criteria
in Section 9.1'1.F of this Ordinance.
3. Density Increase Multipliers.
a) Increases to the dwelling unit or dwelling site base densities
previously determined are allowable if the dimensional standards
in Section 9.3 of this Ordinance are met or exceeded and the
design criteria in Section 9.11.F of this Ordinance are satisfied.
The allowable density increases in Item b below will only be
allowed if structure setbacks from the ordinary high water level are
- 33-
increased to at least fifty (50) percent greater than the minimum
setback, or the impact on the waterbody is reduced an equivalent
amount through vegetative management, topography, or additional
means acceptable to the local unit of government and the setback
is at least twenty-five (25) percent greater than the minimum
setback.

F. Maintenance and Design Criteria
1. Maintenance and Administration Requirements.
a) Before final approval of a planned unit development, adequate
provisions must be developed for preservation and maintenance
in perpetuity of open spaces and for the continued existence and
functioning of the development.
b) Open Space Preservation. Deed restrictions, covenants,
permanent easements, public dedication and acceptance, or other
equally effective and permanent means must be provided to
ensure long-term preservation and maintenance of open space.
The instruments must include all of the following protections:
1. Commercial uses prohibited (for residential PUDs);
2. Vegetation and topographic alterations other than routine
maintenance prohibited;
3. Construction of additional buildings or storage of vehicles
and other materials prohibited; and
4. Uncontrolled beaching of watercraft prohibited.
c) Development Organization and Functioning. Unless an equally
effective alternative community framework is established, when
applicable, all residential planned unit developments must use an
owners association with the following features:
1. Membership must be mandatory for each dwelling unit or
site purchaser and any successive purchasers;
2. Each member must pay a pro rata share of the
association's expenses, and unpaid assessments can
become liens on units or sites;
- 34-
3. Assessments must be adjustable to accommodate
changing conditions; and
4. The association must be responsible for insurance, taxes,
and maintenance of all commonly owned property and
facilities.
2. Open Space Requirements. Planned unit developments must contain
open space meeting all of the following criteria:
a) At least fifty (50) percent of the total project area within the
Shoreland District must be preserved as open space;
b) Dwelling units or sites, road rights-of-way, or land covered by road
surfaces, parking areas, or structures, except water-oriented
accessory structures, or facilities, are developed areas and shall
not be included in the computation of minimum open space;
c) Open space must include areas with physical characteristics
unsuitable for development in their natural state, and areas
containing significant historic sites or unplatted cemeteries;
d) Open space may include outdoor recreational facilities for use by
owners of dwelling units or sites, by guests staying in commercial
dwelling units or sites, and by the general public;
e) Open space may include subsurface sewage treatment systems if
the use of the space is restricted to avoid adverse impacts on the
systems;
1) Open space must not include commercial facilities or uses, but
may contain water-oriented accessory structures or facilities;
g) The appearance of open space areas, including topography,
vegetation, and allowable uses, must be preserved by use of
restrictive deed covenants, permanent easements, public
dedication and acceptance, or other equally effective and
permanent means; and
h) The shore impact zone, based on normal structure setbacks, must
be included as open space. For residential PUDs, at least fifty
(50) percent of the shore impact zone area of existing
developments or at least seventy (70) percent of the shore impact
zone area of new developments must be preserved in its natural
existing state. For commercial PUDs, at least fifty (50) percent of
the shore impact zone must be preserved in its natural state.
3. Erosion Control and Storm Water Management. Erosion Control, storm
water management plans, and Best Management Practices must be
developed and the PUD must:
a) Be designed, and the construction managed, to minimize the
likelihood of serious erosion occurring either during or after
construction. This must be accomplished by limiting the amount
and length of time of bare ground exposure. Temporary ground
covers, sediment entrapment facilities, vegetated buffer strips, or
other appropriate techniques must be used to minimize erosion
- 35-
impacts on surface water features. Erosion control plans
approved by a soil and water conservation district may be required
if project size and site physical characteristic warrant; and
b) Be designed and constructed to effectively manage reasonably
expected quantities and qualities of storm water runoff.
Impervious surface coverage within any tier must not exceed
twenty-five (25) percent of the tier area, except that for
commercial PUDs thirty-five (35) percent impervious surface
coverage may be allowed in the first tier of general development
lakes with an approved storm water management plan and
consistent with Section 9.4 of this Ordinance.
4. Centralization and Design of Facilities. Centralization and design of
facilities and structures must be done according to the following
standards:
a)
b)
c)
Planned unit developments must be connected to publicly owned
water supply and sewer systems.
Dwelling units or sites must be clustered into one or more groups
and located on suitable areas of the development. They must be
designed and located to meet or exceed the following dimensional
standards for the relevant shoreland classification: setback from
the ordinary high water level, elevation above the surface water
features, and maximum height. Setbacks from the ordinary high
water level must be increased in accordance with Section 9.3 of
this Ordinance for developments with density increases;
Shore recreation facilities, including but not limited to swimming
areas, docks, and watercraft mooring areas and launching ramps,
must be centralized and located in areas suitable for them.
Evaluation of suitability must include consideration of land slope,
water depth, vegetation, soils, depth to groundwater and bedrock,
or other relevant factors. The number of spaces >provided for
continuous beaching, mooring, or docking of watercraft must not
exceed one for each allowable dwelling unit or site in the first tier
(notwithstanding existing mooring sites in an existing commercially
used harbor). Launching ramp facilities, including a small dock for
loading and unloading equipment, may be provided for use by
occupants of dwelling units or sites located in other tiers;
d)
Structures, parking areas, and other facilities must be treated to
reduce visibility as viewed from public waters and adjacent
shorelands by vegetation, topography, increased setbacks, color,
or other means acceptable to the local unit of government,
assuming Summer, leaf-on conditions. Vegetative and topographic
screening must be preserved, if existing, or may be required to be
provided;
Accessory structures and facilities, except water oriented
accessory structures, must meet the required principal structure
setback and must be centralized; and
Water oriented accessory structures and facilities may be allowed
if they meet or exceed design standards contained in Section
9.3.0.4 of this Ordinance.
e)
f)
- 36-

G. Conversions. Local governments may allow existing resorts or other land uses
and facilities to be converted to residential planned unit developments if all of the
following standards are met:
1. Proposed conversions must be initially evaluated using the same
procedures for residential planned unit developments involving all new
construction. Inconsistencies between existing features of the
development and these standards must be identified.
2. Deficiencies involving water supply and sewage treatment, structure
color, impervious coverage, open space, and shore recreation facilities
must be corrected as part of the conversion or as specified in the
conditional use permits.
3. Shore and bluff impact zone deficiencies must be evaluated and
reasonable improvements made as part of the conversion. These
improvements must include, where applicable, the following:
a) Removal of extraneous buildings, docks, or other facilities that no
longer need to be located in shore or bluff impact zones;
b) Remedial measures to correct erosion sites and improve
vegetative cover and screening of buildings and other facilities as
viewed from the water; and
c) If existing dwelling units are located in shore or bluff impact zones,
conditions are attached to approvals of conversions that preclude
exterior expansions in any dimension or substantial alterations.
The conditions must also provide for future relocation of dwelling
units, where feasible, to other locations, meeting all setback and
elevation requirements when they are rebuilt or replaced.
4. Existing dwelling unit or dwelling site densities that exceed standards in
Section 9.11.E of this Ordinance may be allowed to continue but must not
be allowed to be increased, either at the time of conversion or in the
future. Efforts must be made during the conversion to limit impacts of
high densities by requiring seasonal use, improving vegetative screening,
centralizing shore recreation facilities, installing new sewage treatment
systems, or other means.

DEVELOPMENT ON SUBSTANDARD LOTS
A.
Purpose:
1. The purpose of regulating development on substandard lots of record is
to coordinate development on substandard lots to insure environmentally
sensitive development, insure compatibility with surrounding existing
development and to allow for combination of lots to the extent possible.
B. Substandard Lot: Development of a substandard lot of record requires sensitivity
and careful attention to issues of drainage, setbacks, floodplain elevation,
grading, lot coverage, existing vegetation cover, and relationship to adjacent
structures. New construction upon substandard lots should be carefully designed
to integrate with the existing neighborhood development. It is the intent of this
section to provide flexibility to develop substandard lots. However, the
requirements outlined herein are intended to define the conditions under which
the City will allow a substandard lot to be developed for single family detached
- 37-
dwelling purposes without a variance. Development or substandard lots of
record which do not comply with these criteria may only be considered after
application for, and approval of, appropriate variances as provided for in Section
7.6 of the Prior Lake Zoning Ordinance.
1. Sewered Areas.
a) A lot of record existing upon the effective date of this Ordinance in
a residential district, located adjacent to a General Development
or Recreational Development Lake, which does not meet the
requirements of this Ordinance as to area or width may be utilized
for single family detached dwelling purposes provided that all of
the conditions of this sub-section apply.
1) The minimum lot size with public sewer shall be a
minimum of fifty (50) feet in width measured at the front
yard setback line and shall have a minimum lot area equal
to or greater than seven thousand five hundred (7,500)
square feet.
2) The lot has been assessed a sewer and water assessment
and will not require an on-site septic system for
development.
3) The lot was created compliant with official controls in effect
at the time.
4) The development plans must be in conformance with the
policies for residential development as outlined in the
Comprehensive Plan.
5) The development plan must not exceed thirty (30) percent
impervious surface coverage.
6) Development must be planned and conducted in such a
manner that the control of disturbed areas and erosion is
demonstrated during and after construction.
7) A complete grading and drainage plan be submitted to the
City Engineer for review. Such plans should be prepared
in accordance with the National Urban Runoff Program
(NURP) Guidelines and Best Management Practices, until
such a time as the City adopts a Storm Water
Management Plan.
8) Any cutting of existing vegetation is minimized to the extent
possible.
9) The lot and proposed structure must meet all other
performance standards of the zoning and building codes.
10) A substandard, R-1 zoned lot of record, which contains fifty
(50) feet of lot width, measured at the required front yard
setback line, may utilize one five (5) foot side yard setback
provided the following conditions apply:
- 38-
.
-
a) The lot is not contiguous to another lot owned in
common by the applicant.
b) No significant trees of twelve (12) inches or more in
caliper will need to be removed to accommodate
the five (5) foot side yard setback.
c) No encroachment into any other required setback
will be necessary.
d) In no case shall a proposed building encroach upon
any recorded easement.
e) There are no written objections from neighbors
located within one hundred (100) feet of the subject
site. The applicant will be required to provide a list
of property owners prepared by a certified abstract
company for notification purposes. Property owners
will be given a ten (10) day notification period in
which to respond to the proposed five (5) foot
setback. Property owners directly adjacent to the
five (5) foot setback side yard shall be notified by
certified mail, or other registered delivery requiring
a return receipt. In the event that no objections are
received, the application may be processed
administratively by staff. In the event that a written
objection is filed within the ten (10) day notification
period, the applicant will be required to file a
variance application and supporting materials
according to the appropriate provisions of the
Zoning Ordinance.
2. Unsewered Lots.
a) If, in a group of two or more contiguous lots under the same
ownership, any individual lot does not meet the requirements of
Section 9.3.A of this Ordinance, thml hall not be considered as
a separate parcel of land for the p 0 s f sale or development.
The lot must be combined with one more contiguous lots so
they equal one or more parcels of land meeting the requirements
of Section 9.3.A of this Ordinance as much as possible.
This ordinance shall become effective from and after its passage and publication.
Passed by the City Council of the City of Prior Lake this 1 st day of March 1993.
