Application received on September 11
BRIEF DESCRIPTION OF THE REQUEST:
The applicant is proposing to subdivide an existing 23.6-acre parcel to create Lots 1 and 2 and
Outlot A. The property is located in the General Rural (GR) District and Shoreland Overlay
District of Long Lake, a Natural Environment Lake.
Lots 1 and 2 would be approximately 5.7 and 5.1 acres in size. The Outlot would include 12
acres.
The proposed driveway for the subdivision requires a variance from the City’s wetland setback
requirement.

DETAILED EVALUATION OF THE SUBDIVISION REQUEST:
Comprehensive Plan
The Comprehensive Plan describes the General Rural District as a residential area of mixed lot
sizes. The Plan states that overall density in the District should meet the Metropolitan Council
requirement of no more than 1 housing unit per 10 acres, but acknowledges that there are a
significant number of existing smaller parcels in the District, that areas around the lakes in
Scandia that do not meet the lot size and density standard, and that this will continue. The
Shoreland Ordinance, which is supported by the Comprehensive Plan, permits new lots with a
minimum size of 5-acres in the first tier around Natural Environment Lakes.
The proposed use of the property is consistent with the goals and policies in the Comprehensive
Plan.
Development Code Requirements: Density, Lot Size, Frontage, and Buildable Area
The Shoreland Overlay District requires that new lots on Natural Environment lakes be at least
5.0 acres in size, and be a minimum 300 feet wide at the OHWL, setback line, and road right-of-
way. The Development Code requires that new lots have a minimum buildable area of 1 acre.
The proposed Lot 1 includes 5.7 acres and will be 389-411 feet wide at the OHWL,
OHWL setback line, and right-of-way of Old Marine Trail.
The proposed Lot 2 includes 5.1 acres and will be 308-337 feet wide at the OHWL,
OHWL setback line, and right-of-way of Old Marine Trail
The proposed Outlot A includes 12.09 acres. The plat indicates significant areas of
wetlands and drainage easements on the parcel, and little buildable area.
The preliminary plat indicates that Lot 1 and Lot 2 each have more than 1.0 acres of
buildable area.
The proposed lots meet the lot size, width, and buildable area requirements of the Development
Code.
Accessory Structures
The existing parcels are vacant. If development is proposed in the future the accessory
structures shall comply with the standards of the Development Code.
Outlot
The Zoning Ordinance defines outlot as “a lot remnant or any parcel of land included in a plat
that is not buildable at the time of platting…it may be a lot that is too small to comply with the
minimum size requirements of zoning and subdivision…”
The applicant is proposing that Outlot A will not remain a part of this subdivision, but would be
combined with the parcel to the west that he owns. While it is more typical that outlots remain
part of the subdivision that created them, the Development Code does not prevent an outlot
from being combined with an adjacent lot. Combining the Outlot with the parcel to the west will
require a lot combination procedure after approval of the subdivision. The City Attorney
Manthey Acres Subdivision Staff Report
Scandia City Council Page 3 October 17, 2017
recommended that there should be a recital in the resolution of approval for the subdivision to
state that the City is not requiring that Outlot A remain a part of the subdivision. The recital is
included in the proposed conditions for approval of the subdivision.
Wetlands and Slopes
The Preliminary Plat shows the locations of the wetland boundaries and proposed drainage and
utility easements. The original Plat did not indicate the setbacks between the proposed
driveway and adjacent wetlands to the east and west. The setback appeared to be very close
to the required 75’, particularly to the wetland to the west of the driveway. At the Planning
Commission meeting and public hearing on September 5, the applicant and his surveyor
responded to questions about the driveway location and stated that the driveway did not meet
the 75’ setback requirement. The application was tabled to permit the applicant to apply for a
variance. The applicant submitted a revised plat that shows that the proposed driveway is 71
feet from Basins 5 and 6, and therefore does not meet the setback requirement.
Setbacks
The required setbacks in the Shoreland Overlay District on Natural Environmental Lakes are:
Setback from the OHWL: 200 feet for structures
150 feet for septic systems
Side yard, parcel >1 acre: 20 feet
Setback from Old Marine Trail (Minor Collector): 100 feet from the centerline or 50 feet
from the right-of-way, whichever is greater
Unclassified water bodies: 75 feet
The proposed driveway location requires a variance from the required structure setback from
wetlands. The Preliminary Plat meets the other setback requirements.
Wastewater Treatment
The Planner sent the plat to at Washington County for comments regarding wastewater
treatment. Alex Pepin’s comments included the following: “The soils look OK there; it appears
that the septic areas meet the wetland setback on the preliminary plat, but the septic areas are
really wedged in there right up to the setback and they will have to be very careful with the
driveway grading. It will be tight, but according to their preliminary plat it appears to meet our
septic requirements.”
The Planner included a proposed condition for approval of the subdivision that the applicant
shall obtain a septic system permit from Washington County.
Lot Coverage
The maximum lot coverage permitted in the Shoreland Overlay District is 25%. Future
development on the parcels shall meet the coverage requirement.

Stormwater Management
The Planner sent the application to the Carnelian-Marine-St. Croix Watershed District for
review. Any district comments will be provided to the Planning Commission at its meeting on
September 5.
The Planner included a condition for approval that the subdivision and future development shall
obtain all necessary Watershed District permits, and that the applicant provide a copy of the
wetland delineation to the Watershed District.
Drainage and Utility Easements
The Engineer reviewed the Preliminary Plat and had the following comments on the Minor
Subdivision:
The Plat should be revised to add a 10’ wide drainage & utility easement just south of
the Old Marine Trail road right-of-way across the entire proposed northern boundary of
Lot 1, Lot 2, and Outlot A. The easement shall be dedicated to the City of Scandia.
The proposed drainage easements should be adjusted accordingly.
The proposed private driveway easement should be adjusted up to the 10’ wide
drainage & utility easement.
The proposed drainage easements should include separate descriptions for Lot 1, Lot 2,
and Outlot A.
The Planner included the Engineer’s proposed conditions in the conditions for approval of the
subdivision.
Shared Driveway
The Development Code requires that each lot have frontage on an improved public roadway,
The proposed driveway meets that requirement. The City has required some standard
conditions for shared driveways that have been approved for other subdivisions, and the City
Engineer advised that for this application, the conditions should read as follows:
In order to provide reasonable access to fire trucks and rescue vehicles, the applicant
shall construct and the property owners shall maintain a minimum 12’ driveway surface
that is capable of supporting emergency vehicle equipment.
The applicant or owners shall maintain a 16’ wide opening around the driveway by
clearing the trees or shrubs as needed.
Any changes to drainage on the lots shall meet the requirements of the Wetland
Conservation Act.
The Planner added these conditions for approval of the subdivision.
Park Dedication
Park dedication is required for new subdivisions. The City has the option to obtain park land or
collect the fee in lieu of land ($3,000 per parcel). The property is not within a Park Search Area
Manthey Acres Subdivision Staff Report
Scandia City Council Page 5 October 17, 2017
identified in the Comprehensive Plan, so the City could propose to collect the park fee of $3,000
in lieu of land for the new parcels. The City Administrator requested that the City Attorney
provide an opinion on whether park dedication should be required for one lot or two lots. The
Attorney advised that the ordinance text requires park dedication for both new lots.
Staff have proposed a condition that the subdivision shall meet the City’s park dedication
requirement. The fee shall be paid before approval of the final plat.
DETAILED EVALUATION OF THE VARIANCE REQUEST:
The proposed location of the shared driveway does not meet the required setback from the
wetland boundaries. The proposed location is 71’ from wetland basins 5 and 6 rather than the
required 75’.
Chapter 1, Section 6.0 of the Development Code includes the criteria and required process for
considering variance requests. Variances may only be granted when the terms of the variance
are consistent with the Comprehensive Plan and in harmony with the general purpose and
intent of the development code. The variance criteria include:
1. The applicant proposes to use the property in a reasonable manner not permitted by the
Development Code.
2. The plight of the landowner is due to circumstances unique to the property not created
by the landowner.
3. The variance, if granted, will not alter the essential character of the locality.
4. Economic conditions alone shall not constitute practical difficulties.
5. The proposed variance will not impair an adequate supply of light and air to adjacent
property, or substantially increase the congestion of the public streets, or increase the
danger of fire, or endanger the public safety, or substantially diminish or impair property
values within the neighborhood.
6. The required variance is the minimum action required to eliminate the practical difficulty.
7. Practical difficulties include, but are not limited to, inadequate access to direct sunlight
for solar energy systems.
Applicants’ Rationale for the Variance
The applicants identified the following practical difficulties that require a variance in order to
construct a driveway to serve Lot 1 and Lot 2:
The property includes several wetlands.
The applicant has proposed a shared driveway in order to try to avoid or minimize
impacts to the wetlands on the parcel.
It is not possible to locate the driveway for Lot 1 in a location on the parcel that would
meet the wetland setback requirement
WCD Review and Comments
Jay Riggs, Washington Conservation District (WCD) Administrator, reviewed the wetland
delineation report, and made the following comments regarding the requested variance: “Based
on our field review, the wetlands are moderate to high quality, but a functions and values
assessment was not completed. The proposed shared driveway location appears to be a
Manthey Acres Subdivision Staff Report
Scandia City Council Page 6 October 17, 2017
reasonable option for minimizing wetland impacts, and I do not have any concerns with regards
to the Wetland Conservation Act.”
Findings
The following bullets present the Planner’s findings related to the Manthey request for a
variance, based on the statutory criteria for granting a variance. Each of the criteria are shown
in italics:
Variances shall only be permitted when they are in harmony with the general purposes
and intent of the official control.
Granting the requested variance is in harmony with the purposes and intent of the
Comprehensive Plan and Development Code based on the following:
o The proposed residential use is permitted in the General Rural District, and a
driveway is required to support that use.
o There is no location on Lot 1 where a driveway could be located outside the
required wetland setbacks.
o The proposed shared driveway and its location will be in harmony with the goals
and policies in the Comprehensive plan because the shared driveway and
proposed location are not likely to have negative impacts on the wetlands where
the setback will be reduced, and will minimize impervious cover in comparison to
having two driveway locations.
The property owner proposes to use the property in a reasonable manner under the
conditions allowed by official control(s).
Single-family residences and driveways are reasonable uses in the GR District. The
proposed use could not be developed without a driveway. The property owner proposes
to use the property in a reasonable way, but cannot do so under the rules of the
Development Code.
The practical difficulties are not caused by the landowner, and are unique to the
property.
The practical difficulties are caused by the locations of several wetlands on the parcel. It
is not possible to develop a driveway on Lot 1 that would avoid impacts to all of these
features.
The variance would not alter the essential character of the area.
Granting the variance would not alter the essential character of the area. The
applicants’ property is surrounded by parcels with single-family residences and vacant
parcels.
Economic conditions alone shall not constitute practical difficulties.
The practical difficulties are caused by the locations of the existing wetlands on the
parcel, and are not related to economic conditions.

The proposed variance will not impair an adequate supply of light and air to adjacent
property, or substantially increase the congestion of the public streets, or increase the
danger of fire, or endanger the public safety, or substantially diminish or impair property
values within the neighborhood.
The proposed variance will not impair the supply of light or air to adjacent properties and
will not increase congestion or endanger public safety. The proposed driveway location
will not impair property values in the neighborhood.
The required variance is the minimum action required to eliminate the practical difficulty.
Construction of the proposed shared driveway with a setback of 71’ from each of the
wetlands is the minimum action required to eliminate the practical difficulty.
Practical difficulties include, but are not limited to, inadequate access to direct sunlight
for solar energy systems.
Granting the variance will provide adequate access to direct sunlight for solar energy
systems.
PLANNING COMMISSION PUBLIC HEARINGS AND RECOMMENDATIONS
The Planning Commission held a public hearing on the proposed subdivision at its meeting on
September 5. One neighbor of the property asked several questions regarding the quality of the
wetlands on the parcels, the proposed outlot, and required structure setbacks. Staff responded
to the questions. The Commission asked the project surveyor about the distance between the
wetland boundaries and proposed driveway. It was determined that the driveway did not meet
the wetland setback requirements. The Commission tabled the request and requested the
applicant to submit a variance request for the proposed driveway location.
The Commission held a public hearing on the variance request at their meeting on October 3. A
resident asked questions about the driveway drainage easements and proposed location of the
septic system. The Planner responded that the City Engineer and County reviewed the
easements and septic system location and provided comments and recommended conditions,
which were included in the staff report.
Council Member Kronmiller commented that he opposes granting variances, and questioned the
rationale for granting this variance. He observed that the city seems to grant every variance
requested. The Planner responded that she has generally followed the League of Minnesota
Cities attorneys’ guidance materials regarding the interpretation of criteria for granting variances
and the guidance of the city attorney, and that the staff recommendation is based on that
guidance. The Commission discussed the issue and noted that the variance request is
relatively minor and meets the criteria for granting a variance from their perspectives, and that
the City’s staff screen variance applications and advise potential applicants about whether their
proposed variance is likely to be recommended for approval or does not meet the criteria for
variance approval, and advise applicants about changes that could be made to improve the
request, so that applicants do not spend time and money applying for variances that are unlikely
to be approved. Therefore the variance applications have been “screened” prior to submission
Manthey Acres Subdivision Staff Report
Scandia City Council Page 8 October 17, 2017
to the City, and those that do not meet the variance criteria do not come forward or are revised
to better meet the criteria.
The Planner noted that the City has recently granted several variances from the wetland
setback requirement, and that this may indicate a need to review the requirement. She stated
that in many communities, wetland setbacks or buffers vary based on the quality of the wetland,
and low to moderate quality wetlands typically require buffers and setbacks that are less than
75’ wide. This reduces the likelihood that variances may be needed for structures located near
low or moderate quality wetlands. The Planning Commission will review the wetland setback
requirements as it develops the City’s updated Shoreland Ordinance.
The Commission recommended approval of the subdivision and variance.
