FROM: Nathan Fuerst, AICP, Consulting Planner
AGENDA ITEM: Lake Elmo Elementary - Conditional Use Permit, Variance, and Preliminary
Plat
REVIEWED BY: Jason Stopa, Community Development Director
Sophia Jensen, City Planner
BACKGROUND:
As a result of an assessment of school facility needs, Stillwater Area Public Schools (ISD 834, hereafter
referred to as the “School District”) has identified the need for a new elementary school facility in Lake
Elmo’s South Planning Area. The School District has identified the subject property as a preferred
location for a new elementary school to replace the aging Lake Elmo Elementary located Northeast of
the intersection of Lake Elmo Blvd N. and Stillwater Blvd. N.
On March 6, 2024, the City Council approved an amendment to the City’s Comprehensive Plan and
Zoning Map to allow for the establishment of the public-school use on the subject property. Since that
time, the School district’s team has been compiling detailed development plans for the site.
The following applications represent entitlements required for this project:
1. Conditional Use Permit (CUP) – The Public Facilities zoning district requires a CUP for this
use, a public school. The CUP will cover use of the entire site.
2. Subdivision – The School District’s is proposing to develop an unplatted property. Consistent
with other development, the School District is required to plat the property through the major
subdivision process, this is due to the previously unknown need for public right of way
dedication and improvements.
3. Variance – Variances to the maximum lot area in the PF District and location of a drive in a
buffer area are required.
ISSUE BEFORE THE CITY COUNCIL:
Should the City Council approve the CUP, Subdivision, and Variance requests to allow the Lake Elmo
Elementary School to move forward?

Land Use Conformance. The subject property received a comprehensive plan amendment and rezoning
approval through Resolution 2024-029 and Ordinance 2024-07, respectively, on March 6, 2024. The
proposed land use, a public school, is consistent with the future land use, Institutional, and zoning
district, Public Facilities, where it is a conditional use.
Minimum Lot Area. The Lake Elmo Elementary School site is comprised of one parcel 47.59 acres in
area. This is above the City’s maximum lot area of 20 acres. Because the school is seeking to subdivide
this property as required by the City, the City has also required a variance be approved to the 20 acre
maximum. Staff support a variance to the City’s maximum lot size due to the fact that a great majority
of this property is encumbered by the buffer for the Oakdale Gun Club. Additionally, as this property is
located at the intersection of two county roads, there are significant distances required for the two
entrances from that intersection, reducing the ability to subdivide this property in a manner more
conforming with the City’s ordinance.
MN Shooting Range Protection Act: In May 2005, Minnesota Governor Tim Pawlenty signed into law
the Shooting Range Protection Act. It became effective on May 28, 2005, becoming Minnesota Statutes,
3
Chapter 87A. This Statute protects existing shooting ranges from becoming noncompliant as a result of
adjacent development. State law establishes a 750 foot buffer from the shooting range property
boundary. In that area, the law prevents the establishment of any land use which would cause the
shooting range to become nonconforming with the performance standards for shooting ranges which
were adopted by reference in state statute.
The elementary school is proposed on a parcel abutting a portion of the Oakdale Gun Club. When the
application was initially discussed, City staff explored this issue and reviewed the performance
standards for shooting ranges in person at the MN DNR’s Central Office. Staff’s initial finding was that
the only performance standard requiring further review was statutory noise limits created by State
Statute 87A.05 Noise Standards.
The Stillwater Area School District was required to submit a noise study which tested the noise levels
generated by the Oakdale Gun Club to determine whether the establishment of any new uses on site
would be over the allowable levels in statute. The noise study, completed by Veneklasen Associates,
measured noise levels at four different locations in the 750’ buffer area. Measurements were taken
during the week after the 4th of July, when the Oakdale Gun Club is open to the general public and
therefore it’s busiest time of year. The Study concludes that the noise generated at all four testing
locations is below the maximum levels in state statue for a Public School, which has the most sensitive
Noise Area Classification (NAC) in statue.
Staff required the noise study be revised to include an assessment of sound levels at the testing locations
during the fall period with leaf-off conditions when higher caliber rifles are typically used more
frequently at the Oakdale Gun Club. The acoustic consultant has provided an updated memo containing
methodology and updated findings based on modeling and past attendance records shared by Oakland
Gun Club. The findings show that even with fall conditions, all testing points remain under the state
statutory noise threshold.
Tree Preservation. The subject property is heavily wooded with many densely planted qualifying
significant trees requiring protection under the City’s ordinance. A significant amount of the trees on
this parcel will need to be removed for the School District’s proposed improvements, with removals
mostly concentrated on the east half of the site. Tree removals are proposed in part due to a need for
mass grading to allow improvements such as stormwater management, drives, parking areas, ball and
recreational fields, and the school building.
The School District has proposed an exception to the City’s Tree Mitigation Standards under LEC
105.12.460 (f). The rationale is that the former property owner, who had owned the property for over
three decades, planted the majority of trees on site between 1990 and 2003. In the areas on site where
the previous owner planted trees, they were planted in a grid-like pattern similar to tree farms in terms of
species composition and planting proximity.
The City’s ordinance allows for exceptions to tree mitigation requirements if all the following conditions
exist:
A. It is not feasible to combine the subject parcel with adjacent parcels that could use the parcel as
required green space;
4
B. Strict adherence to the City's tree preservation and replacement standards would prevent
reasonable development that is consistent with the Comprehensive Plan and desirable to the City
on the parcel; and
C. The exception requested is the minimum needed to accomplish the desired development or
redevelopment.
The City Council may provide partial or full relief to tree mitigation requirements under LEC
105.12.460. The City may consider multiple forms of relief, depending on which form of relief best
balances the objectives of the City and tree preservation. The City may also require payment of a fee-in-
lieu of tree replacement.
Summary of Tree Mitigation Data:
• Total Significant Tree Caliper inches on site (existing) = 29,296
• Total Significant Tree Caliper inches to be removed = 23,411
• Total Significant Tree Caliper inches planted by Previous Owner = 27,327
• Total ‘Previous Owner Planted’ Significant Inches Removed = 20,653
Mitigation Required Without Exception:
A. Total Significant Tree Caliper inches on site (existing) = 29,296 inches
B. Total Significant Tree Caliper inches to be removed = 23,411 inches
C. (A x .3) Allowable Removal (caliper inches) = 8,788 inches
D. (B - C) Mitigation Inches = 14,623 inches
E. (D x .5) Evergreen Replacement Inches = 7,312 inches
F. Evergreen Replacement Trees (1 standard tree = 3”) = 2,437 trees
G. Cash in Lieu Fee ($325/caliper inch) = $2,376,400
Mitigation Required With Exception for Owner Planted Trees:
A. Total Significant Tree Caliper inches on site (not planted by previous owner) = 1969
B. Total Significant Tree Caliper inches to be removed (not planted by previous owner) = 1314
C. (A x .3) Allowable Removal (caliper inches) = 591 inches
D. (B - C) Mitigation Inches = 723 inches
E. (D x .5) Evergreen Replacement Inches = 362 inches
F. Evergreen Replacement Trees (1 standard tree = 3”) = 121 trees
G. Cash in Lieu Fee ($325/caliper inch) = $117,650
The City’s Landscape Architect’s 9/12/2024 review memo requires further clarification of tree removal
data to understand the requirements for replacement. Staff recommend consideration of a fee of $325 per
unmitigated caliper inch, but not to exceed $50,000, in exchange for flexibility provided through the
exception requested for this project.
Landscaping. The City’s Landscape Architect has reviewed the planting plan for conformance with the
City’s ordinance and commented on necessary plan revisions in their 9/12/2024 review memo. The
Applicant will need to recalculate the total number of trees that are required for tree mitigation.
Additional information such as provisions for irrigation, species diversity requirements, and other details
will be required in a future resubmittal. A condition of approval is added requiring conformance to the
City Landscape Architect’s Memo.

Buffering and Screening. City Code Section 105.12.970 (f)(2) requires a 150-foot buffer from abutting
residential properties. While the school building and nearly all site improvements meet the building
setback requirement, a driveway access for the busses will be located within 38’ of the northern property
line. The parcel immediately to the north is undeveloped but is zoned Rural Single Family. This
necessitates a variance to the buffering standard. Key rationale include mandatory access spacing
requirements for safety along Lake Elmo Avenue, and that the nearest home to the north of the proposed
drive is over four hundred feet away.
Trees are proposed in the landscaping plan to line the school’s northern driveway access and would help
to recreate the vegetative buffer along with existing vegetated areas that will be preserved.
Building Design. Elevations submitted with the site plans indicate a new school building which is
designed with primary materials including brick, glass, and architecturally treated metal. In its design,
the building has facades which vary in design with contrasting building materials and colors and creates
visual interest. The building materials and façade elevations proposed are consistent with the City code
and design standards manual for such structures and are therefore found acceptable.
Parking. City code requires three spaces per classroom. There are 53 rooms that are classrooms or an
equivalent learning space. Therefore, a minimum of 159 parking spaces are required. There are a total of
211 parking spaces supplied in in the southern parking area, and a total of 13 adjacent to the bus parking
to create a total on site of 224 spaces. This site meets the parking minimum established by code.
Winter performance of the parking lot is an important consideration for safety and the reduction of
chloride use. The following suggestions are made to improve performance:
• Snow storage areas should be identified on grading plans.
• Grading of snow storage areas should be considered in order to reduce meltwater sprawl onto
surfaces treated with chlorides.
• Tree plantings and other landscaping should be carefully located such that plantings are not
destroyed by winter maintenance activities or salt from snow piles.
Traffic and Access. This project is served by two county roads, Lake Elmo Avenue North and 10th
Street North. A traffic study was required and supplied by the Applicant. Both the study and site plans
have been reviewed by the City Engineer and Washington County for issues related to traffic and access.
Washington County will ultimately require an access permit for the use and is the responsible
jurisdiction for county roads. Washington County has provided the following requirements in its letter
which are paraphrased here for brevity:
1. Turn Lanes are required for both access points.
2. Queuing on to county roads will not be permitted. Washington County is now planning to
improve the intersection of CSAH 10 and 17 in 2028.
3. A traffic light or roundabout is required at the entrance to the School (10th ST. N. entrance) this
will be expected at the School District’s cost.
4. The bus entrance on Lake Elmo Avenue may be restricted to a ¾ access intersection with
northern ‘left-outs’ prohibited.
5. Queuing on county roads will be prohibited.
6
6. It is suggested that the School District provide options for safe walking routes to school for
students who wish to do so.
The City Engineer provided a review memo dated 9/23/24 with the following comments related to
Transportation Improvements and Access:
1. Access Management. The Proposed access locations along both Lake Elmo Avenue (CSAH 17)
and 10th Street (CSAH 10) must be approved by Washington County.
2. Turn Lane Improvements. As part of the site improvements, dedicated right and left turn lanes
must be constructed along Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10) at both
access locations. Turn lanes must be constructed meeting Washington County standards.
3. Intersection Control Improvements. Traffic Control Improvements must be included as part of
the site improvements for the opening of the school as recommended by Washington County. A
traffic signal is required at the new access location along 10th Street North (CSAH 10), complete
with crosswalks. A temporary wood pole traffic signal, or alternate traffic control improvement
approved by Washington County, is required at the intersection of Lake Elmo Avenue (CSAH
17) and 10th Street (CSAH 10), compete with crosswalks.
4. Emergency Service Access. Emergency vehicle access to and throughout the site must be
reviewed and approved by the Lake Elmo Fire Department.
5. Bituminous Trails. The site improvements include the construction of a bituminous trail along
the east and south sides of the site along Lake Elmo Avenue and 10th Street. The grading plans
should be revised to eliminate the drainage swale obstruction that will impede any future
extension of the trail to the west along 10th Street. Consideration should also be given to the
provision of pedestrian connectivity internal to the school property and connection to the County
Park Preserve.
Due to the fact that Washington County is planning improvements at the intersection of Lake Elmo
Avenue and 10th Street North, City staff anticipates that there will be additional future costs to the City
that must be accounted for. With the County’s cost share policy, the primary costs to the City would be
the right of way acquisition and stormwater management. Due to the new Lake Elmo Elementary at this
location, the County has accelerated plans for infrastructure improvements to improve service after
determining improvements necessary due to the traffic study. The City’s staff suggest the following
requirements to address cost impacts to the City:
1. The Plat shall dedicate right of way as needed for future county intersection improvements.
2. The School District shall design the stormwater ponds to accommodate the needs for stormwater
management at the new intersection of CSAH 10 & 17.
3. The City will require a cost participation from the Applicant at no more than 50% of the City's
cost or $250,000, whichever is less, to account for the costs of the future intersection
improvements at County Roads 10 & 17.
CONDITIONAL USE PERMIT FINDINGS: City Code Section 105.12.290(a) provides findings
required for Conditional Use Permit approval. Staff recommends the following findings:
1. The proposed use will not be detrimental to or endanger the public health, safety, comfort,
convenience or general welfare of the neighborhood or the city. Approval of a conditional
use permit should not be detrimental to or endanger the public health, safety, comfort,
convenience or general welfare of the neighborhood or City. The City has required that the
Applicant submit evidence to determine impacts on woodlands, traffic, and noise.
7
2. The use or development conforms to the City of Lake Elmo Comprehensive Plan. This use
is consistent with the Comprehensive Plan as amended by Resolution 2024-029.
3. The use or development is compatible with the existing neighborhood. The proposed land
use, an elementary school, is permitted as a conditional use and is compatible with
surrounding residential development.
4. The proposed use meets all specific development standards for such use listed in Article 15
of this Chapter. The conditional use permit amendment meets all specific development
standards of Article 15. Variances to the lot area maximum and buffer distances are
proposed.
5. If the proposed use is in a flood plain management or shoreland area, the proposed use meets
all the specific standards for such use listed in Chapter 105.12.1260 (Shoreland Regulations)
and Title 100 (Flood Plain Management). The proposed uses will not be within the
floodplain, and the property does not fall within the City’s shoreland overlay district.
6. The proposed use will be designed, constructed, operated and maintained so as to be
compatible in appearance with the existing or intended character of the general vicinity and
will not change the essential character of that area. The proposed new building is designed to
be compatible with the City’s design standards.
7. The proposed use will not be hazardous or create a nuisance as defined under this Chapter to
existing or future neighboring structures. It is not anticipated for the use to become a
nuisance as the site will meet applicable performance standards.
8. The proposed use will be served adequately by essential public facilities and services. The
Applicant has requested a utility feasibility study and intends to connect the parcel to the
public sewer system as required under the City’s ordinance. Washington County and City
engineering staff have suggested conditions of approval that would mitigate impacts
expected to county roadways.
9. The proposed use will not create excessive additional requirements at public cost for public
facilities and services and will not be detrimental to the economic welfare of the community.
The use will provide an expanded capacity to serve area residents with educational
services. Intersection improvements, or cost participation in future improvements required
due to this use, are required by the City to mitigate City costs on public infrastructure
improvements.
10. The proposed use will not involve uses, activities, processes, materials, equipment and
conditions of operation that will be detrimental to any persons, property or the general
welfare because of excessive production of traffic, noise, smoke, fumes, glare or odors. The
use will not produce excessive noise, smoke, fumes, glare or odors. Washington County
and City engineering staff have suggested conditions of approval that would mitigate
impacts expected to county roadways.
11. Vehicular approaches to the property, where present, will not create traffic congestion or
interfere with traffic on surrounding public thoroughfares. Washington County and City
engineering staff have suggested conditions of approval that would mitigate impacts
expected to county roadways.
12. The proposed use will not result in the destruction, loss or damage of a natural or scenic
feature of major importance. The proposed expansion will meet applicable performance
standards. Environmental features on site will be preserved where possible, with most tree
occurring on the east side of the property.

SUBDIVISION FINDINGS.
The process for review of subdivisions is established in Title 103 of City Code. To approve a
Preliminary Plat, the City shall make the determination that the project does not meet the findings for
denial established in code section 103.00.090(d)(2) as follows:
a. That the proposed subdivision is in conflict with the city's comprehensive plan, development
code, capital improvements program, or other policy or regulation.
b. That the physical characteristics of the site, including, but not limited to, topography, vegetation,
susceptibility to erosion and siltation, susceptibility to flooding, water storage, and retention, are
such that the site is not suitable for the type or intensity of development or use contemplated.
c. That the design of the subdivision or the proposed improvements are likely to cause substantial
and irreversible environmental damage.
d. That the design of the subdivision or the type of improvements will be detrimental to the health,
safety, or general welfare of the public.
e. That the design of the subdivision or the type of improvement will conflict with easements on
record or with easements established by judgment of a court.
f. That the subdivision is premature as determined by the standards of this title.
VARIANCE FINDINGS.
An applicant must establish and demonstrate compliance with the variance criteria set forth in Lake
Elmo City Code Section 105.12.320 before the City may grant an exception or modification to city code
requirements. These criteria are listed below, along with comments from Staff about the applicability of
these criteria to the applicant’s request. Staff recommends the following findings:
1) Practical Difficulties. A variance to the provision of this chapter may be granted by the Board of
Adjustment upon the application by the owner of the affected property where the strict enforcement
of this chapter would cause practical difficulties because of circumstances unique to the individual
property under consideration and then only when it is demonstrated that such actions will be in
keeping with the spirit and intent of this chapter. Definition of practical difficulties - “Practical
difficulties” as used in connection with the granting of a variance, means that the property owner
proposes to use the property in a reasonable manner not permitted by an official control.
Parcel Size: The use proposed by the Applicant will be on a property of 47.59 acres less required
right of way dedication. The lot area variance is needed due to the desire to locate uses on site
outside of the buffer established around the Oakdale Gun Club property, and the need to locate
accesses at acceptable distances from the intersection of CSAHs 10 & 17.
Buffer: The northern driveway access to Lake Elmo Avenue is proposed with a distance of
approximately 38 feet from the northern lot line. Due to the requirement to meet access spacing
requirements intended to protect public safety, the access should not be moved any further south.
In the proposed location of the drive is approximately 400 feet away from the residence to the
north.
2) Unique Circumstances. The plight of the landowner is due to circumstances unique to the property
not created by the landowner.
Parcel Size: The Applicant is not proposing to expand the area of the property. The existing
conditions on site were not created by the Applicant.
9
Buffer: The Applicant is proposing accesses that are responsive to Washington County
engineering requirements and cannot move the northern drive out of the buffer area.
3) Character of Locality. The proposed variance will not alter the essential character of the locality in
which the property in question is located.
Parcel Size/Buffer: The variances will not impact the essential character of the area. The request
meets the City’s design standards.
4) Adjacent Properties and Traffic. The proposed variance will not impair an adequate supply of light
and air to properties adjacent to the property in question or substantially increase the congestion of
the public streets or substantially diminish or impair property values within the neighborhood.
Parcel Size/Buffer: The variance should not impair adjacent properties. Washington County and
City engineering staff have suggested conditions of approval that would mitigate impacts expected
to county roadways.

PUBLIC COMMENT:
Notice of a public hearing was sent to surrounding property owners and published in the Stillwater
Gazette. The Planning Commission held a public hearing on October 16, 2024. One written comment
concerning the amount of tree removals with opposition to the requested exception to tree mitigation
was filed with the City before the meeting. Three residents provided public comment on the proposal
and focused comments on the following topics as summarized by staff:
• Concern about the amount of tree removal
• Opposition for exception requested to tree mitigation standards
• Opposition to variance requests
• Concerns for traffic speeds and safety along the corridor
• Concerns and questions about roadway improvements or possible widening
• Noise impacts from Oakdale Gun Club on elementary school
OPTIONS:
The City May:
• Approve the request;
• Approve the request with conditions (staff recommendation);
• Deny the request citing findings of fact for denial.
PLANNING COMMISSION ACTION:
After holding the public hearing for the School District’s requests, the Planning Commission discussed
the proposal at its October 16, 2024 meeting. In its discussion, the Planning Commission considered the
tree removals, required access points, infrastructure improvements, noise study, and trail connectivity.
The Planning Commission ultimately voted 3-2 to recommend the item for City Council approval with
Staff’s recommended findings and conditions. Dissenting planning commissioners noted a desire for
reduced tree removal or additional tree replacement.

RESOLUTION NO. 2024-114
A RESOLUTION APPROVING THE REQUEST WITH CONDITIONS FOR VARIANCES
AT 10928 10th STREET NORTH
WHEREAS, the City of Lake Elmo is a municipal corporation organized and existing
under the laws of the State of Minnesota; and
WHEREAS, Stillwater Area Schools, ISD 834, (the “Applicant”), owner of the property
located at 10928 10th Street North, PID# 26.029.21.44.0001, Lake Elmo, MN 55042 (the
“Property”) has submitted an application to the City of Lake Elmo (the “City”) for variances to
maximum lot area and buffer areas in order to permit the establishment of a new Lake Elmo
Elementary School; and
WHEREAS, notice has been published, mailed, and posted pursuant to the Lake Elmo
Zoning Code, Section 105.12.250; and
WHEREAS, the Lake Elmo Planning Commission held a public hearing on October
16th, 2024 to review and consider the Variances; and
WHEREAS, the Lake Elmo Planning Commission has submitted its report and
recommendation of approval to the City Council as part of a Staff Memorandum dated
November 6th 2024; and
WHEREAS, the proposed Lake Elmo Elementary includes one parcel along with
dedication of public right of way northwest of 10th Street N and Lake Elmo Avenue N; and
WHEREAS, the City Council considered said matter at its November 6th 2024 meeting
and voted to approve the Variances with findings and conditions for approval; and
NOW, THEREFORE, based on the testimony elicited and information received, the
City Council makes the following:
FINDINGS
1) Practical Difficulties as used in connection with the granting of a variance, means that the
property owner proposes to use the property in a reasonable manner not permitted by an
official control:
Parcel Size: The use proposed by the Applicant will be on a property of 47.59 acres less
required right of way dedication. The lot area variance is needed due to the desire to locate
uses on site outside of the buffer established around the Oakdale Gun Club property, and
2
the need to locate accesses at acceptable distances from the intersection of CSAHs 10 &
17.
Buffer: The northern driveway access to Lake Elmo Avenue is proposed with a distance of
approximately 38 feet from the northern lot line. Due to the requirement to meet access
spacing requirements intended to protect public safety, the access should not be moved any
further south. In the proposed location of the drive is approximately 400 feet away from
the residence to the north.
2) Unique Circumstances the plight of the landowner is due to circumstances not created by
the landowner:
Parcel Size: The Applicant is not proposing to expand the area of the property. The
existing conditions on site were not created by the Applicant.
Buffer: The Applicant is proposing accesses that are responsive to Washington County
engineering requirements and cannot move the northern drive out of the buffer area.
3) Character of Locality the proposed variance will not alter the essential character of the
locality in which the property in question is located:
Parcel Size/Buffer: The variances will not impact the essential character of the area. The
request meets the City’s design standards.
4) Adjacent Properties and Traffic the proposed variance will not impair an adequate
supply of light and air to properties adjacent to the property in question or substantially
increase the congestion of the public streets or substantially diminish or impair property
values within the neighborhood:
Parcel Size/Buffer: The variance should not impair adjacent properties. Washington
County and City engineering staff have suggested conditions of approval that would
mitigate impacts expected to county roadways.
DECISION
NOW, THEREFORE, BE IT FURTHER RESOLVED, and based upon the
information received and the above Findings, that the City Council of the City of Lake Elmo
hereby approves the request with conditions for a variance request to allow a parcel maximum of
47.6 acres, and a drive up to 38’ from the northern property boundary for the Lake Elmo

MEMORANDUM
To: Nicole Miller, City Administrator, Lake Elmo
From: Paul Aplikowski | PA
Date: August 23, 2024
Comm. No: 232224
Subject: Independent School District #834
Submittal to City of Lake Elmo on behalf of Stillwater Area Public Schools, for the
proposed New Lake Elmo Elementary School project, located at the intersection of
Lake Elmo Avenue North and 10th Street North, Lake Elmo, Minnesota (Property ID
#2602921440001)
Conditional Use Permit, Preliminary Plat, and Variance Submittal Narrative:
On behalf of Stillwater Area Public Schools, we are submitting for City staff review a Conditional
Use Permit, Preliminary Plat, and Variance application for the proposed new Lake Elmo
Elementary School. Stillwater Area Public Schools is excited to continue to serve elementary-aged
students at a larger school within the city of Lake Elmo. The proposed 1,100-student elementary
school building would replace the current Lake Elmo Elementary School located at 11030 Stillwater
Boulevard, Lake Elmo, Minnesota. The new building is proposed to be a total of 148,700 square feet
and will be predominately a two-story structure. The building will staff about 130 employees. The
anticipated school day schedule is currently planned to be from 7:45 a.m. – 2:15 p.m. Projected
mobilization, ground-breaking, and building construction is planned to commence in Spring of
2025. Construction is expected to be completed by August 2026.
Since the initial sketch plat application, the zoning of the parcel has been revised from Agricultural
(A) to Public Facilities (PF) and the comprehensive plan has been updated to amend future land use
from Rural Area Development (RAD) to Institutional (INST) as well as adjusting the MUSA
boundary to include this site. As the subject site to be developed is over the maximum size of 20
acres, we are now requesting a variance to develop the entire 47.6-acre parcel.
In reaction to the city and county comments that were received on the initial sketch plat application,
the proposed site plan has gone through several iterations. Included in these changes are the
addition of trails on the south and east sides of the parcel and moving the bus parking entry further
north to comply with the required quarter-mile separation from an intersection. Also, based on the
submitted traffic study, the internal vehicle stacking has been increased to keep car queuing off the
adjacent roads.
As requested, a sound study of the site has been conducted and the site has been found to be in
compliance with sound codes. Given the receptor type, the modified MPCA code criterion is that
the sound level at the property line (or anywhere on the project) cannot exceed a sound level of 63
dBA when measured over a period of one hour. The loudest hourly sound level that was measured
was 55 dBA attributable to gun club activities at the closest measurement location at the property
line. As sound decays with distance, the decibel level continues to drop the further the observer gets
from the source. Additionally, all locations of all sound sensors were reviewed and approved by
city staff prior to the start of sound data collection.
Also included in this submittal is the completed traffic study which was previously submitted to
the City along with the Oak-Land Middle School submittal currently under review.

MEMORANDUM
To: City of Lake Elmo Date: August 20, 2024
From: Larson Engineering Project No: 12236128.000
Project: New Lake Elmo Elementary School
Thank you in advance for reviewing our request for an exception to the City of Lake Elmo’s Tree
Preservation and Replacement Ordinances. Stillwater Area Public Schools is planning to
construct a new elementary school within the City of Lake Elmo. This school will be designed to
accommodate 1,100 students and will benefit the local community and meet the requirements set
forth by the City of Lake Elmo.
This Memo provides specific design aspects from an engineer’s perspective of the site and
outlines design decisions and explains why the New Lake Elmo Elementary is impacting such a
large number of trees and why the school is looking to receive an exception for tree preservation.
When designing a new school, one of the first considerations is the proposed layout of the site.
There are quite a few elements that go into the initial consideration of a site layout such as
potential access points to the site, adjacent parcel uses & zoning designations, drainage patterns,
existing wetlands/landlocked basins, and grading. Listed below are major design factors that
were identified when designing the site layout the proposed elementary school.
➢ Access Points & County Road: Since the first concept design of the site, the layout
intended to have two entry points to access the site. The reason for two access points was
to separate student drop-off/teacher parking from the entry that services the school busses
and trucks for deliveries. This practice promotes far greater safety throughout the site as
the school district can better regulate the flow of traffic through their site. These entry
points need to be roughly a quarter mile from intersection of Lake Elmo Ave North and
10 Street North which is a standard county requirement to promote safety at intersections
and allow traffic queuing at the intersection without inhibiting the access points. In
addition, trails are required along both County Roads to service the local community.
➢ Adjacent Parcels: Parcels directly abutting the proposed new school site consist of either
residential homes, public park, or a gun club. The gun club was the primary concern
after reviewing the adject parcels.
➢ Drainage Patterns, Wetlands, and Landlocked basin: The existing site is broken down
into two major drainage areas that split the site from roughly its northwest corner to its
southeast corner. These drainage areas flow to landlocked basin located on the site. A
landlocked basin is low area where water flows to and has no way of escaping even is
major rainfall events, these lowland areas would have to fill up with stormwater around
15-20 feet over a vast area to have any chance of leaving the site. There were no
wetlands identified on the parcel.

➢ Grading: The existing site has a vast variation in grades as the high point of the site is
over 46 feet of vertical difference from the low point of the site and there are relatively
no flat areas other than the northwest corner of the site.
The design factors above all have significant impact on design of the site and overall impact on
the trees. The next section will directly outline how each of these design criteria impacted the
tree preservation of the site.
➢ Access Points & County Road: These entry points to the site provide roughly a quarter
mile separation from intersection of Lake Elmo Ave North and 10 Street North as this is a
standard with Washington County. Both of proposed locations enter the site in highly
wooded areas. The entry on the northeast side of the site off of Lake Elmo Ave North has
no flexibility in its location as it cannot be pushed further North as it’s already near the
edge of the property and it also can’t push further south at its already just under the
Washington County’s desired quarter mile spacing from the intersection and the County
will prohibit moving the entry any further south. The entry on the south side of the site
off of 10th Street North has the flexibility to move further West but would impact an
existing right turn lane but not further east due to Washington County’s desired quarter
mile spacing from the intersection. The proposed design kept the south entry as east as
possibly as this design option would have the east impact on trees.
In Addition to the access points a trail was required on the south and east side of the
property adjacent to the county roads this requirement was from both the County and the
City of Lake Elmo. Due to the existing topography adjacent to the county road the
proposed trail required the design had to make significant modifications to the
topography alongside the county road. The topography was revised to provide both a
trial consistent with City and County standards and also to create a new drainage way for
the runoff from the county road that would not inhibit the trail, this had significant
impacts on the existing trees due to the revised topography.

Ave North and 10TH Street North

➢ Adjacent Parcels: The gun club being an adjacent parcel had a significant impact on the
layout of the site. A 750 foot buffer was used from the edge of the gun club’s property
when determining the layout of the site. This buffer is shown in Image #3 below.
Pushing out proposed site layout to the East side of the site had a significant impact on
trees as this side of the parcel which was farmed less and had a greater number of trees
and vegetation.
Image #3
➢ Drainage Patterns, Wetlands, and Landlocked basin: The overall site was designed to
maintain existing drainage patterns and preserve the existing landlocked basin to meet the
Valley Branch Watershed Districts requirements.
The southern landlocked basin was significantly impacted by the access point entering
the site due to vast grade change between the landlocked basin and the entry drive. This
caused a large number of trees to be impacted, in addition the volume taken away from
the land locked basin due entry drive had to be made up in that landlocked basin, this
meant further grading was required in the basin to restore the volume back to what it was,
this in turn impacted additional trees.
The landlocked basin on the North side of the site was expanded due to request from
Washington County as they plan on improving Lake Elmo Ave North and 10TH Street
North in the future, on going coordination is still being done to finalize coordinating the
stormwater need of the County, but this expansion of the landlocked basin also impacted
additional trees. The expanded landlocked basin can be seen on the North side of the site
in Image #1 which was referenced above, in addition Image #4 depicted below shows the
flood elevations of the existing landlocked basin.

➢ Grading: The existing topography of the site has large variations in grades and lack any
large flat areas to propose improvements such a school, parking lots, ball fields, soccer
fields, and any other amenities typically found at an elementary school. The vast
variation of grades can be seen below in Image #5. To design a site that would provide
all these amenities, the site needed to be mass graded to provide flatter areas. The mass
grading of the site was done in a way to maintain as many trees a feasibly possible while
still proving amenities that will service the school district and the public.
Image #5
The design choices listed above outline why trees throughout the site were impacted. These
choices, along with the other site factors and the fact that the site is heavily wooded, seem to be
reasonable justifications for providing an exception to the tree preservation requirements.

For those slopedareas which must be disturbed, use techniques such as phasing and stabilization practicesdesigned for steep slopes (e.g., slope draining and terracing).3.Stabilize all exposed soil areas (including stockpiles). Stabilization must be initiated immediately tolimit soil erosion whenever any construction activity has permanently or temporarily ceased on anyportion of the site and will not resume for a period exceeding 14 calendar days (or 7 days if withinone mile of an identified impaired water). Stabilization must be completed no later than 14calendar days (or 7 days if within one mile of an identified impaired water) after the constructionactivity has ceased.4.Stabilization is not required on constructed base components of roads, parking lots, and similarsurfaces. Stabilization is not required on temporary stockpiles without significant silt, clay ororganic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sandstockpiles) but sediment controls must be placed at the base of the stockpile.5.For Public Waters that the Minnesota Department of Natural Resources has promulgated “work inwater restrictions” during specified fish spawning time frames, all exposed soil areas that are within200 feet of the water's edge, and drain to these waters must complete the stabilization activitieswithin 24 hours during the restriction period.6.Stabilize the normal wetted perimeter of the last 200 linear feet of temporary or permanentdrainage ditches or swales that drain water from the site within 24 hours after connecting to asurface water or property edge. Stabilize remaining portions of temporary or permanent ditches orswales within 14 calendar days (or 7 days if within one mile of an identified impaired water) afterconnecting to a surface water or property edge and construction in that portion of the ditchtemporarily or permanently ceases.7.Temporary or permanent ditches or swales being used as sediment containment systems duringconstruction (with properly designed rock-ditch checks, bio rolls, silt dikes, etc.) do not need to bestabilized during the temporary period of use as a sediment containment system. These areasmust be stabilized within 24 hours after no longer being used for as a sediment containmentsystem.8.Applying mulch, hydromulch, tackifier, polyacrylamide or similar erosion prevention practices is notacceptable within any portion of the normal wetted perimeter of a temporary or permanentdrainage ditch or swale section with a continuous slope of greater than 2 percent.9.Pipe outlets must be provided with temporary or permanent energy dissipation within 24 hoursafter connection to a surface water or permanent stormwater treatment system.10.Route water around unstabilized areas on the site and to reduce erosion, unless infeasible. Useerosion controls and velocity dissipation devices such as check dams, sediment traps, riprap, orgrouted riprap at outlets within and along the length of any constructed stormwater conveyancechannel, and at any outlet, to provide a non‐erosive flow velocity, to minimize erosion of channelsand their embankments, outlets, adjacent stream banks, slopes, and downstream waters duringdischarge conditions.11.Unless infeasible due to lack of pervious or vegetated areas, direct discharges from BMPs tovegetated areas of the site (including any natural buffers) in order to increase sediment removaland maximize stormwater infiltration. Use velocity dissipation devices if necessary to preventerosion when directing stormwater to vegetated areas.12.Infiltration areas shall not be excavated until all upstream areas have been stabilized and/orupstream BMPs are in place to properly prevent sediment deposition. Only low impact equipmentshall be allowed in infiltration areas which shall be clearly identified, staked, and marked/fencedoff.13.Project phasing shall be implemented to ensure land disturbance and temporary erosion controlmeasures can be effectively inspected and maintained throughout the duration of the project inaccordance with the Inspection and Maintenance requirements of Section 11.TEMPORARY SEDIMENT CONTROL PRACTICES (SECTION 9)1.Sediment control practices must be established on all down gradient perimeters and be locatedupgradient of any buffer zones. The perimeter sediment control practices must be in place beforeany upgradient land‐disturbing activities begin. These practices shall remain in place until FinalStabilization has been established.2.If downgradient sediment controls become overloaded, based on frequent failure or excessivemaintenance requirements, additional upgradient sediment control practices or redundant BMPsshall be installed to eliminate the overloading concerns. All changes shall be recorded in theSWPPP.3.Temporary or permanent drainage ditches and sediment basins designed as part of a sedimentcontainment system (e.g., ditches with rock-check dams) require sediment control practices onlyas appropriate for site conditions.4.A floating silt curtain placed in the water is not an acceptable sediment control BMP except whenworking on a shoreline or below the waterline. Immediately after construction activity (e.g.,installation of rip rap along the shoreline) in that area is complete, upland perimeter controlpractices shall be installed if exposed soils still drain to a surface water.5.Re‐install all sediment control practices that have been adjusted or removed to accommodateshort‐term activities such as clearing or grubbing, or passage of vehicles, immediately after theshort‐term activity has been completed. Complete any short‐term activity that requires removal ofsediment control practices as quickly as possible and re‐install sediment control practices beforethe next precipitation event even if the short‐term activity is not complete.6.All storm drain inlets must be protected by appropriate BMPs during construction until all sourceswith potential for discharging to the inlet have been stabilized. Inlet protection may be removed fora particular inlet if a specific safety concern (street flooding/freezing) has been identified by thePermittee(s) or the jurisdictional authority (e.g., city/county/township/MnDOT engineer).ThePermittee(s) must document the need for removal in the SWPPP.7.Temporary soil stockpiles must have silt fence or other effective sediment controls, and cannot beplaced in any natural buffers or surface waters, including stormwater conveyances such as curband gutter systems, or conduits and ditches unless there is a bypass in place for the stormwater.8.Where vehicle traffic leaves any part of the site (or onto paved roads within the site) install avehicle tracking BMP to minimize the track out of sediment from the construction site. Examples ofvehicle tracking BMPs include (but are not limited to) rock pads, mud mats, slash mulch, concreteor steel wash racks, or equivalent systems. Use street sweeping if such vehicle tracking BMPs arenot adequate to prevent sediment from being tracked onto the street.9.The Permittee(s) must install temporary sedimentation basins as required in accordance withpermit requirements.10.Minimize soil compaction by restricting vehicle access in areas where final vegetative stabilizationwill occur, unless otherwise infeasible.11.Discharges from BMPs shall be directed to vegetated areas unless infeasible.12.Preserve a 50 foot natural buffer or (if a buffer is infeasible on the site) provide redundant (double)perimeter sediment controls when a surface water is located within 50 feet of the project's earthdisturbances and stormwater flows to the surface water.13.Perimeter sediment controls shall be installed at least 5 feet apart unless limited by lack ofavailable space. Natural buffers are not required adjacent to road ditches, judicial ditches, countyditches, stormwater conveyance channels, storm drain inlets, and sediment basins. If preservingthe buffer is infeasible, the reasons for which shall be recorded in the SWPPP.14.The use of polymers, flocculants, or other sedimentation treatment chemicals, if used on theproject, shall be used in accordance with accepted engineering practices, dosing specifications,and sediment removal design specifications provided by the product manufacturer or supplier. Useconventional erosion and sediment controls prior to the chemical addition to ensure effectivetreatment. Chemicals may only be applied where treated stormwater is directed to a sedimentcontrol system which allows or filtration of settlement of the floc prior to discharge.15.If the proposed project as shown on the plans has 10 or more acres draining to a common locationor 5 acres or more if the site is within one mile of a special or impaired water (as identified inSection II - Receiving Waters and Environmentally Sensitive Areas), then a temporary sedimentbasin must be constructed as shown on the plans. Temporary sediment basins will have aminimum of 3,600 cubic feet of storage per acre draining to the basin. The basin outlet shallprovide for discharging water from the surface to minimize discharging of pollutants. A stabilizedemergency overflow shall be constructed.DEWATERING AND BASIN DRAINING (SECTION 10)1.Discharge turbid or sediment‐laden waters related to dewatering or basin draining (e.g., pumpeddischarges, trench/ditch cuts for drainage) to a temporary or permanent sediment basin on theproject site unless infeasible. Discharge from the temporary or permanent sedimentation basins tosurface waters if the basin water has been visually checked to ensure adequate treatment hasbeen obtained in the basin and that nuisance conditions will not result from the discharge. If thewater cannot be discharged to a sedimentation basin prior to entering the surface water, it must betreated with the appropriate BMPs, such that the discharge does not adversely affect the receivingwater or downstream properties.2.Discharge water that contains oil or grease, must use an oil‐water separator or suitable filtrationdevice (e.g. cartridge filters, absorbents pads) prior to discharging the water.3.All water from dewatering or basin‐draining activities must be discharged in a manner that doesnot cause nuisance conditions, erosion in receiving channels or downslope properties, erosion orscour in the immediate vicinity of discharge points, or inundation in wetlands causing significantadverse impact to the wetland.4.The use of filters with backwash water, haul the backwash water away for disposal, return thebackwash water to the beginning of the treatment process, or incorporate the backwash water intothe site in a manner that does not cause erosion. Discharge backwash water to the sanitary sewerif permission is granted by the sanitary sewer authority. Replace and clean the filter media used indewatering devices when required to retain adequate function.INSPECTIONS AND MAINTENANCE (SECTION 11)1.Owner and Contractor shall ensure that a trained person (as identified in item 21.2.b) of the permit willinspect the entire construction site at a minimum:- Once every seven (7) days during active construction, and- Within 24 hours after a rainfall event greater than 1/2 inch in 24 hours2.Inspect all erosion prevention and sediment control BMPs and Pollution Prevention ManagementMeasures to ensure integrity and effectiveness during all routine and post‐rainfall event inspections. Allnonfunctional BMPs must be repaired, replaced, or supplemented with functional BMPs by the end of thenext business day after discovery, or as soon as field conditions allow access unless another time frameis specified below. Investigate and comply with the following Inspection and Maintenance requirements:a.All perimeter control devices must be repaired, replaced, or supplemented when they becomenonfunctional or the sediment reaches one‐half (1/2) of the height of the device. These repairs mustbe made by the end of the next business day after discovery, or thereafter as soon as field conditionsallow access.b.Temporary and permanent sedimentation basins must be drained and the sediment removed whenthe depth of sediment collected in the basin reaches one‐half (1/2) the storage volume. Drainage andremoval must be completed within 72 hours of discovery, or as soon as field conditions allow access.c.Inspect and photograph dewatering discharges at the beginning and at least once every 24 hoursduring operation.d.Surface waters, including drainage ditches and conveyance systems, must be inspected for evidenceof erosion and sediment deposition during each inspection. Remove all deltas and sedimentdeposited in surface waters, including drainage ways, catch basins, and other drainage systems, andrestabilize the areas where sediment removal results in exposed soil. The removal and stabilizationmust take place within seven (7) days of discovery unless precluded by legal, regulatory, or physicalaccess constraints. Use all reasonable efforts to obtain access. If precluded, removal and stabilizationmust take place within seven (7) calendar days of obtaining access. Contact all local, regional, stateand federal authorities and receiving any applicable permits, prior to conducting any work in surfacewaters.e.Construction site vehicle exit locations must be inspected for evidence of off‐site sediment trackingonto paved surfaces. Tracked sediment must be removed from all paved surfaces both on and off sitewithin 24 hours of discovery, or if applicable, within a shorter time.f.Streets and other areas adjacent to the project must be inspected for evidence of off‐siteaccumulations of sediment. If sediment is present, it must be removed in a manner and at a frequencysufficient to minimize off‐site impacts (e.g., fugitive sediment in streets could be washed into stormsewers by the next rain and/or pose a safety hazard to users of public streets).5.Inspection frequency adjustment:a.Inspections of areas with permanent cover can be reduced to once per month, even if constructionactivity continues on other portions of the site; orb.where sites have permanent cover on all exposed soil and no construction activity is occurringanywhere on the site, inspections can be reduced to once per month and, after 12 months, may besuspended completely until construction activity resumes. The MPCA may require inspections toresume if conditions warrant; orc.where construction activity has been suspended due to frozen ground conditions, inspections may besuspended. Inspections must resume within 24 hours of runoff occurring, or upon resumingconstruction, whichever comes first.3.All inspections and maintenance activities within 24 hours of being conducted must be recorded andretained in the SWPPP. These records must include:a.Date and time of inspectionsb.Name of person(s) conducting inspectionsc.Findings of inspections, including the specific location where corrective actions are neededd.Corrective actions taken (including dates, times, and party completing maintenance activities)e.Date and amount of all rainfall events greater than 1/2 inch (0.5 inches) in 24 hours. Rainfall amountsmust be obtained by a properly maintained rain gauge installed onsite, a weather station that is within1 mile of your location or a weather reporting system that provides site specific rainfall data from radarsummaries.f.If any discharge is observed to be occurring during the inspection, a record of all points of the propertyfrom which there is a discharge must be made, and the discharge should be described (i.e., color,odor, floating, settled, or suspended solids, foam, oil sheen, and other obvious indicators of pollutants)and photographed.g.Any amendments to the SWPPP proposed as a result of the inspection must be documented withinseven (7) calendar days.4.All infiltration areas must be inspected to ensure that no sediment from ongoing construction activity isreaching the infiltration area. All infiltration areas must be inspected to ensure that equipment is not beingdriven across the infiltration area.POLLUTION PREVENTION MANAGEMENT MEASURES (SECTION 12)Implement the following pollution prevention management measures on the site:1.Storage, Handling, and Disposal of Construction Products, Materials, and Wastes shall comply with thefollowing to minimize the exposure to stormwater of any of the products, materials, or wastes. Productsor wastes which are either not a source of contamination to stormwater or are designed to be exposed tostormwater are not held to this requirement:a.Building products that have the potential to leach pollutants must be under cover (e.g., plasticsheeting or temporary roofs) to prevent the discharge of pollutants or protected by a similarly effectivemeans designed to minimize contact with stormwater.b.Pesticides, herbicides, insecticides, fertilizers, treatment chemicals, and landscape materials must beunder cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants orprotected by similarly effective means designed to minimize contact with stormwater.c.Hazardous materials, toxic waste, (including oil, diesel fuel, gasoline, hydraulic fluids, paint solvents,petroleum‐based products, wood preservatives, additives, curing compounds, and acids) must beproperly stored in sealed containers to prevent spills, leaks or other discharge.

RE: Lake Elmo Elementary School Tree Mitigation Exception Request
The new Lake Elmo Elementary School project is requesting an exception to the City’s tree preservation
and replacement standards. Standards for tree preservation exceptions by City Council are dictated by
Lake Elmo City Code Section 105.12.470.f.1
The proposed project site for the new Lake Elmo Elementary School is an existing agricultural field with a
significant amount of coniferous tree rows planted by the previous landowner. These trees are primarily 8”-
12” caliper red pines, scotch pines, blue spruce, and norway spruce. Per the historic aerial imagery below,
these gridded tree rows were planted between 1991 and 2003.
1991 Aerial Image 2003 Aerial Image
2014 Aerial Image 2024 Aerial Image
To develop this site for the new elementary school, a significant amount of the previous landowner planted
trees will need to be removed for the elementary building, parking, driveways, utilities, and stormwater
management. Diligent efforts were made by the Architect and Civil Engineer to limit site disturbance to the
East side of the property while maintaining the necessary functions and features of the elementary school.
Because a significant portion of the tree removals would be previous landowner planted trees, the project
is requesting that these landowner planted trees be exempt from a tree mitigation penalty.

The following sections of Lake Elmo City Code pertain to this request. Beneath each section of city code is
a description about how this section applies to the Lake Elmo Elementary School site.
105.12.470 Tree Preservation Section c.1.b.5
A Tree Preservation Plan is not required for the following activities: Tree removal related to public
improvement projects and maintenance or repairs to existing streets, roadways, sewers, parks, storm water
facilities and utility infrastructure.
The proposed Elementary School is a public improvement project . The ballfields and playground
will be open to the public.
105.12.470 Tree Preservation Section c.3.c
Trees that were planted as part of a commercial business such as a tree farm or nursery do not need to be
inventoried on an individual basis. A general description of the trees and an outer boundary of the planted
area must be provided. The burden of proof shall be on the applicant to provide evidence to support the
finding that the trees were planted as part of a commercial business.
Per the attached aerial imagery from 1991-2024, a significant portion of the coniferous trees on this
agricultural site were planted by the previous landowner between 1991 and 2003. The gridded layout
mimics a standard tree farm planting plan. The attached tree inventory chart documents these
landowner planted trees as primarily 8”-12” caliper coniferous trees including red pine, scotch pine,
blue spruce, and norway spruce.
105.12.470 Tree Preservation Section c.5.c-d
The following types of trees do not need to be included as part of the tally of tree removals:
c. Trees that were planted as part of a commercial business, such as a tree farm or nursery (subject to
verification by the City); or
d. Trees that were planted by the current property owner. In making such a determination, the City shall
consider consistency of the age of the trees, any patterns in the location of trees, historical aerial
photography and evidence of intentional planting such as invoices, formal planting plans or cost sharing
agreements.
Per the attached aerial imagery from 1991-2024, a significant portion of the coniferous trees on this
agricultural site were planted by the previous landowner between 1991 and 2003. The gridded layout
mimics a standard tree farm planting plan. The attached tree inventory chart documents these
landowner planted trees as primarily 8”-12” caliper coniferous trees including red pine, scotch pine,
blue spruce, and norway spruce.

105.12.470 Tree Preservation Section f.1: Exception Standards
Not withstanding the City’s desire to accomplish tree preservation and protection goals, there may be
instances where these goals are in conflict with other City objectives. These conflicts will most likely occur
on small, heavily-wooded parcels. The City recognizes there may be instances where it is not practical or
reasonable to have an applicant plant the total required replacement trees on site.
Applicants may ask the City to approve exceptions to the City’s tree preservation and replacement
standards. The City Council may grant exceptions if all of the following conditions exist:
a. It is not feasible to combine the subject parcel with adjacent parcels that could use the parcel as
required green space;
b. Strict adherence to the City’s tree preservation and replacement standards would prevent
reasonable development that is consistent with the Comprehensive Plan and desirable to the City
on the parcel; and
c. The exception requested is the minimum needed to accomplish the desired development or
redevelopment.
a. Within the site’s limits, the project will support and maintain new trees around the
development area to meet the Lake Elmo landscape and screening requirements. However,
it is not feasible for the Elementary School to plant and continue to maintain additional
mitigation trees on property or an adjacent parcel. Rather than funding on-site amenities for
elementary students, taxpayer dollars would be going towards a substantial tree mitigation
penalty due to the loss of the previous landowner’s planted tree rows.
b. This project is a reasonable development that is consistent with the goals of the
Comprehensive Plan. A new Elementary School is an essential public service for the City of
Lake Elmo, especially in a geographically ideal location near the Middle School.
c. The Architect and Civil Engineer have worked diligently to minimize site disturbance while
maintaining all of the necessary functions and features for the Elementary School including
parking, driveways, utilities, and stormwater management.
105.12.470 Tree Preservation Section f.2: Reduced Mitigation for Exceptions
If the City Council approves an exception to the tree preservation standards, relief from the requirements
of the standards may take the form of reduced mitigation requirements, greater allowable tree removal,
higher thresholds for determining significant trees, or any combination of the above. The City Council will
determine which form of relief best balances the objectives of the City and tree preservation.
The proposed Lake Elmo Elementary School project requests that the City Council exempt the
landowner planted trees from a mitigation penalty. The project intends to meet the Lake Elmo
standard landscape requirements and mitigation penalty for the removal of naturally occurring site
trees.
The proposed Elementary School is an essential public service and provides public improvements
including ballfields and a playground that will be open to the community. With this tree mitigation
exemption, the school will be able use more of the budget for the elementary students’ building ,
site amenities, and education.

Spot spray thistles, etc.Establishment (fall seeding):1)Prepare site - Late August - early September2)Seed - late September to freeze-upMaintenance (following season):1)Mow (6-8 inches) - once in May, June, and July2)Weed Control - mowing should keep annual weeds down. Spot spray thistles, etc.Evaluation:1)Cover crop growing within 2 weeks of planting (except dormant plantings).2)Seedlings spaced 1-6 inches apart in drill rows.3)Native grass seedlings may only be 4-6 inches tall.4)If there is a flush of growth from foxtail etc., mow as necessary.Year 2Maintenance:1)Mow (6-8 inches) one time between June 1 - August 15 before weeds set seed.2)Weed Control - mowing should keep annual weeds down. Spot spray thistles, etc.3)Some sites may not require much maintenance the second year.Evaluation:1)Cover crop will be gone unless winter wheat was used in a fall planting.2)Grasses forming clumps 1-6 inches apart in drill rows, but still short.3)Some flowers should be blooming (black-eyed Susans, bergamot, etc.).4)If there is a flush of growth from foxtail etc., mow site.Year 3Maintenance:1)Mow only if necessary.2)Weed Control - Spot spray thistles, etc.3)Sites usually do not require much maintenance the third year.Evaluation:1)Planting should begin looking like a prairie - tall grasses, flowers, etc.Long-termMaintenance:1)Weed Control - Spot spray thistles, etc.2)Burning (3-5 year rotation) alternate spring and fall if possible.3)Haying (3-5 year rotation) late summer or early fall. Alternate with burning (may substitute for burning).4)Burning two years in a row will really "clean up" rough-looking sites.MNDOT Seed Type 'B' areas noted per plan: (unless otherwise noted on civil plans), shall be:MnDOT Wet Ditch seed mixture, drilled into the topsoil layer at 20.0 lbs per acre.

Memorandum www.srfconsulting.com 3701 Wayzata Boulevard, Suite 100 | Minneapolis, MN 55416-3791 | 763.475.0010 Fax: 1.866.440.6364 An Equal Opportunity Employer SRF No. 17789 To: Stillwater Area Public Schools From: Brent Clark, PE, Project Manager Eric Wurst, EIT, Traffic Engineer I Date: August 1, 2024 Subject: New Lake Elmo Elementary School & Oak-Land Middle School Transportation Study Introduction SRF has completed a transportation study for the new proposed Lake Elmo Elementary School and additions to the existing Oak-Land Middle School (see Figure 1: Project Location). The proposed Elementary School, which is expected to replace the existing Lake Elmo Elementary School, is located in the northwest quadrant of the Lake Elmo Avenue North (CSAH 17) and 10th Street North (CSAH 10) intersection in the City of Lake Elmo, MN. The new elementary school, which is expected to open in Fall of 2026, is anticipated to have approximately 1,100 students and 130 staff members. The existing Oak-Land Middle School is located in the southwest quadrant of the Manning Avenue North (CSAH 15) and 10th Street North (CSAH 10) intersection. Planned renovations include a proposed 16,000 square foot gymnasium and a 29,500 square foot classroom addition. The capacity of the school is expected to increase from 950 to 1,250 students with 125 total staff. Therefore, the main objectives of the transportation study are to review existing operations within the study area, evaluate transportation impacts to the adjacent roadway network based on the new elementary school and additions to the middle school, and recommend any necessary improvements to provide safe and efficient operations for all modes of transportation. The following information provides the assumptions, analysis, and recommendations offered for consideration. Existing Conditions Existing conditions were reviewed to identify any existing operational and/or safety issues within the study area. The evaluation of existing conditions included various data collection efforts, including traffic data, roadway characteristics, pedestrian/bicycle facilities, crash history, school observations, and an intersection capacity analysis, which are summarized in the following sections.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 3 Study Intersections The following study intersections represent the primary focus of the transportation study. These intersections, categorized for each respective school, were identified through discussions with the project team as they relate to potential school impacts, as well as future area infrastructure needs. Lake Elmo Elementary School: 10th Street North (CSAH 10)/Keats Avenue North (CSAH 19) 10th Street North (CSAH 10)/Lake Elmo Avenue North (CSAH 17) Lake Elmo Avenue North (CSAH 17)/Hudson Boulevard Oak-Land Middle School: Manning Avenue North (CSAH 15)/10th Street North (CSAH 10) Manning Avenue North (CSAH 15)/Oak-Land Middle School North Access Manning Avenue North (CSAH 15)/Oak-Land Middle School South Access Traffic Data SRF collected 24-hour vehicular and pedestrian/bicyclist turning movement counts at the study intersections on Thursday, May 23, 2024, while area schools were in session. The existing Oak-Land Middle School hours are currently between 7:50 a.m. and 2:20 p.m., and the peak hours of the study area are summarized below. Note that the school arrival peak hour coincides with the a.m. peak hour of the adjacent roadway, which is 7:00 a.m. to 8:00 a.m. AM Peak Hour: 7:00 a.m. to 8:00 a.m. School Departure Peak Hour: 2:00 p.m. to 3:00 p.m. PM Peak Hour: 4:00 p.m. to 5:00 p.m. It should be noted that crack sealing construction was occurring along Manning Avenue during data collection efforts. While the construction resulted in sporadic lane/shoulder closures throughout the day, Manning Avenue remained open, and travel patterns were not expected to be impacted as a result of the construction. In addition, on-going construction along I-94 may be causing various regional traffic impacts between Oakdale and the St. Croix River, however, based on discussions with the county staff, the traffic volumes collected were considered representative of the study area. Roadway Characteristics A field assessment was completed to identify various roadway characteristics within the transportation system study area, such as functional classification, general configuration, and posted speed limit. A summary of these roadway characteristics is shown in Table 1. Note that these are general characteristics and that there are some deviations within the area or segments of the roadways. For example, Keats Avenue transitions from a 4-lane divided A-Minor Expander to a 2-lane divided local street north of 10th Avenue.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 4 Table 1. Existing Roadway Characteristics (1) Functional Classification based on the City of Lake Elmo’s 2040 Comprehensive Plan. (2) Functional classification transitions from an A-Minor Reliever to a Minor Collector east of Manning Avenue. (3) Functional classification transitions from a Major Collector to an ‘Other Arterial’ north of 10th Street. (4) Keats Avenue transitions from 4-lane divided A Minor Expander with a speed limit of 55-mph to a 2-lane divided local street with a speed limit of 35-mph north of 10th Street. (5) Speed limit change occurs north of Hudson Boulevard, with a posted speed limit of 55-mph to the north, and 50-mph to the south. From a traffic control perspective, the Manning Avenue/10th Street and Manning Avenue/Oak-Land Middle School south access intersections are signalized, and the 10th Street/Keats Avenue and 10th Street/Lake Elmo Avenue intersections are unsignalized with all-way stop control. All other study intersections are unsignalized with side-street stop control. Existing geometrics, traffic controls, and traffic volumes in the study area are shown in Figure 2. Pedestrian and Bicycle Facilities A field assessment was completed to identify the current local and regional pedestrian/bicycle facilities within the study area and is illustrated in Figure 3. While Keats Avenue (CSAH 19) has an off-street trail that provides connectivity from Woodbury to the Lake Elmo Park Reserve, the rest of the study roadways generally lack off-street pedestrian/bicycle facilities. It should be noted that the high speeds (i.e. 55-mph) along these roadways likely deter most pedestrians and bicyclists from using the shoulder. In general, the nearby local neighborhood developments include internal pedestrian/bicycle facility networks. Given the close proximity of these residential neighborhoods to the two school sites, it is important to consider pedestrian/bicycle connectivity within the project area. Further discussion regarding pedestrian/bicycle considerations is provided later in this document. Safety Analysis A safety analysis was completed to understand any crash trends or geometric issues at the study intersections. The safety analysis was based on reported crashes using MnDOT’s Crash Mapping Analysis Tool (MnCMAT2) from April 1, 2019, to March 31, 2024, which represents the most recent five-year period available. Results of the safety analysis are summarized below and shown in Figure 4, while detailed crash type/rate information is included in the Appendix.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 8 o There was a total of 24 crashes reported within the study area during the analysis period. The number of crashes ranged from a high of nine (9) crashes at the 10th Street/Lake Elmo Avenue intersection to a low of one (1) crash at the 10th Street/Keats Avenue and Manning Avenue/Oak-Land Middle School South Access intersections. o In order to determine the significance of the crashes, crash rates were calculated for each intersection and compared to average crash rates published by MnDOT for intersections with similar characteristics (i.e., traffic control, traffic volumes, lighting, environment, etc.) A higher than average rate does not necessarily indicate a significant crash problem. Therefore, critical rates were calculated to determine the statistical significance. If the actual rates are below the critical rates, crashes that occurred may be due to the random nature of crashes and not necessarily a geometric design or traffic control issue. Based on the results of analysis, which is illustrated in Figure 4, no study intersections are above the critical crash rate, indicating that no study intersections have a statistically significant crash problem. o It should be noted that one (1) fatal and four (4) serious injury crashes have occurred within the study area during the analysis period. Descriptions of the fatal/serious injury crashes, which are based on the police reports, are summarized below: o 10th Street/Lake Elmo Avenue – Fatal single vehicle run-off-road crash. Driver ran a stop sign at high speed, before exiting the roadway and hitting a tree. Based on the police report, the driver was intoxicated at the time of the crash. o Lake Elmo Avenue/Hudson Boulevard – Serious injury head-on crash. Driver crossed the centerline, colliding with oncoming traffic. Based on the police reports, drugs/alcohol may have played a role in the crash. o Lake Elmo Avenue/Hudson Boulevard – Serious injury angle crash. Side-street vehicle failed to observe right-of-way and pulled out into oncoming traffic. o 10th Street/Manning Avenue – Serious injury left-turn crash. Westbound left turning vehicle failed to yield to oncoming vehicle with green light. o 10th Street/Manning Avenue – Serious injury left-turn crash. Eastbound left turning vehicle failed to yield to oncoming vehicle with green light. o All eight (8) of the multi-vehicle crashes that occurred at the 10th Street/Lake Elmo Avenue were the result of vehicles running the stop signs or failing to yield right-of-way. o Six (6) of the seven (7) crashes at the Lake Elmo Avenue/Hudson Boulevard intersection were either minor injury or serious injury crashes, a majority of which were angle crashes.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 9 Lake Elmo Elementary School Observations SRF conducted observations of the parent pick-up/drop-off operations at the existing Lake Elmo Elementary School during the week of May 20th, 2024, to gather general trip rate information and assess potential storage needs for the new site. This data, along with queuing data from other schools and ITE trip generation standards, was important for estimating the operations expected at the relocated elementary school. Oak-Land Middle School Observations As mentioned previously, the Oak-Land Middle School hours of operations are currently between 7:50 a.m. and 2:20 p.m. The middle school, which serves grades 7-9, currently has an enrollment of approximately 950 students. In order to identify current travel patterns and any access, circulation, pick-up/drop-off, and/or pedestrian crossing issues, field observations were performed at the school. A summary of the middle school operations during the a.m. and school departure peak periods are shown in Figure 5 and 6, respectively. The trip generation for the school during the peak hours is summarized in Table 2. Table 2.

The North Access is a three-quarter access designated for buses only from 7:00 a.m. to 3:00 p.m. The lot operates as a counterclockwise loop with buses entering from the access along Manning Avenue and looping around the lot to reach the bus pick-up/drop-off area, located on the north side of the school. Given the access restriction, approximately five (5) to 16 buses were observed to make U-turn movements at the Manning Avenue/South Access intersection during school peak hours. The South Access is the primary access for staff/visitor parking and parent pick-up/drop-off operations. Parents will queue in a counterclockwise one-way loop and pick-up/drop-off students in a designated area, immediately adjacent to the main building access. In addition to staff members, a school resource officer is positioned in the area during school dismissal to help facilitate the process and direct students from the building access.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 12 During school arrivals, parents start arriving at the school around 7:05 a.m. and buses begin to arrive around 7:25 a.m., with the school starting at 7:50 a.m. Internal queueing was observed to extend onto Manning Avenue for approximately ten (10) minutes, however, the queues were maintained with the turn lane storage, and were not observed to affect mainline traffic. The school area was generally clear by 7:50 a.m. During afternoon pick-ups, travel patterns were generally the same as the morning drop-off. Students were released at 2:20 p.m., and most students were picked up and the school area was cleared within 15 minutes. Parents were observed to arrive at the school early, with some parents arriving as early as 1:45 p.m. Internal queueing was observed to extend onto Manning Avenue starting at 2:10 p.m., and queues nearly maxed out the turn lane storage at the intersection. Despite guidance from staff, some students were observed to cut across the parking lot to get picked up from their parents. In general, the overall operations during the school arrival and departure periods were observed to be safe and efficient. The only safety issues observed were when students would walk across the pick-up queue and parking lot to get to their parents’ vehicle. Despite signage, parents often would not pull up past the main school entrance, leaving potential on-site queueing storage underutilized. While internal queues that extended onto Manning Avenue were observed to be maintained within the turn lane storage, there may be occurrences throughout the year where these queues extend beyond the turn lanes, causing friction and additional conflict points along Manning Avenue. Intersection Capacity Analysis An existing intersection capacity analysis was completed using Synchro/SimTraffic software to establish a baseline condition to which future traffic operations can be compared. The capacity analysis was completed for the weekday a.m., school departure, and p.m. peak hour of the adjacent roadway network. Capacity analysis results identify a Level of Service (LOS) which indicates how well an intersection is operating. Intersections are graded from LOS A through LOS F. The LOS results are based on average delay per vehicle results from SimTraffic, which correspond to the delay threshold values shown in Table 3. LOS A indicates the best traffic operation and LOS F indicates an intersection where demand exceeds capacity. Overall intersection LOS A through D is generally considered acceptable by drivers in the Twin Cities Metropolitan Area. Table 3. Level of Service Criteria for Signalized and Unsignalized Intersections LOS Designation Signalized Intersection Average Delay/Vehicle (seconds) Unsignalized Intersection Average Delay/Vehicle (seconds) A ≤ 10 ≤ 10 B > 10 - 20 > 10 - 15 C > 20 - 35 > 15 - 25 D > 35 - 55 > 25 - 35 E > 55 - 80 > 35 - 50 F > 80 > 50
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 13 For side-street stop-controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an unsignalized intersection with side-street stop control can be described in two ways. First, consideration is given to the overall intersection level of service. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support these volumes. Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, the majority of delay is attributed to the side-street approaches. It is typical of intersections with higher mainline traffic volumes to experience high-levels of delay (i.e., poor levels of service) on the side-street approaches, but an acceptable overall intersection level of service during peak hour conditions. Schools generally have higher peaking characteristics as compared to the typical roadway network during the a.m. and p.m. peak hours (i.e., traffic on/near school grounds tend to be busy for a short period of time close to school start and end times). The study focused on analyzing and publishing findings for the 60-minute interval, which is the traffic industry standard. Additionally, peak 15-minute intervals were reviewed to provide context on any operational issues occurring immediately before or after school start and end times. Results of the existing intersection capacity analysis, shown in Table 4, indicate that all study intersections, other than the 10th Street/Keats Avenue intersection, currently operate at an acceptable overall LOS D or better during the a.m., school departure, and p.m. peak hours.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 14 The following information summarizes the operational and/or queuing issues identified as part of the existing conditions analysis: 10th Street/Keats Avenue: o The overall intersection operates at a LOS F (63 seconds) during the p.m. peak hour, and the eastbound and westbound approaches (i.e., 10th Street) both have delays of 70 seconds or greater and 95th percentile queues of 600 feet or greater. o The intersection is atypical for an all-way stop control, with multiple turn lanes and a wide center median along Keats Avenue. Drivers were observed to be confused on who had the right-of-way, and several turning movements occurred simultaneously mid-intersection. o Note the intersection is ranked as the number 3 priority intersection within the Washington County 2023 Intersection Control Ranking System (ICR S) Report and is programmed within the Washington County 2024-2028 Capital Improvement Plan for roundabout evaluation/preliminary design in 2027. 10th Street/Lake Elmo Avenue:
o While the overall intersection operates at an acceptable LOS D (27 seconds), the eastbound approach operates at a LOS E (43 seconds) with 95th percentile queues of approximately 375 feet during the p.m. peak hour. o While the intersection is below the average crash rate, there have been eight (8) crashes in the last five (5) years that involved vehicles running the stop sign or failing to yield right-of-way. Manning Avenue/Oak-Land Middle School South Access:
o As mentioned previously, parent pick-up/drop-off queues were observed to extend onto Manning Avenue for short durations (i.e., 10-minutes) during both the school arrival and departure peak hours. During site observations these queues were observed to be maintained within turn lane storage, however, there may be occurrences throughout the year where these queues extend beyond the turn lanes, which may cause friction and additional conflict points along Manning Avenue.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 15 Proposed School Projects As mentioned previously, both the new Lake Elmo Elementary School and Oak-Land Middle School additions are expected to be completed and open in Fall of 2026. Oak-Land Middle School The existing Oak-Land Middle School is located in the southwest quadrant of the Manning Avenue (CSAH 15) and 10th Street (CSAH 10) intersection. Planned renovations, which are illustrated in Figure 7, include a proposed 16,000 square foot gymnasium and a 29,500 square foot classroom addition. The capacity of the school is expected to increase from 950 to 1,250 students with 125 total staff. No parking lot or vehicular access changes are planned as part of the renovation project. Note classes are scheduled to take place for approximately 172 days of the year. Lake Elmo Elementary School The new proposed Lake Elmo Elementary School, shown in Figure 8, is located in the northwest quadrant of the Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10) intersection in the City of Lake Elmo. The new elementary school is expected to replace the existing Lake Elmo Elementary School, which is located in the northeast quadrant of the Lake Elmo Avenue/Stillwater Boulevard intersection. The new elementary school is anticipated to have a maximum enrollment of 1,100 students and 130 staff members. Note the current enrollment of Lake Elmo Elementary is approximately 650 students, however, for the purpose of this study the year of opening (2026) with the maximum enrollment was analyzed to provide a conservative estimate. Classes are scheduled to take place approximately 168 days of the year. Access to the elementary school is proposed at the following two (2) locations: • Main School Access: Located along 10th Street, approximately 1,225 feet west of 10th Street/Lake Elmo Avenue intersection; this access would be the primary access for staff/visitor parking and will also serve parent pick-up/drop-off operations. • Bus Access: Located along Lake Elmo Avenue, approximately 1,250 feet north of the 10th Street/Lake Elmo Avenue intersection; this access is intended for buses/utility vehicles only for the school. Further discussion regarding the site plan is documented later in this study.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 18 Traffic Forecasts To evaluate traffic impacts associated with the two school projects, traffic forecasts were developed for the year 2026 build conditions. The following information summarizes the year 2026 traffic forecast development process. School Time Changes Based on discussions with the school district, school times are expected to change prior to Year 2026 conditions and are summarized in Table 5. To account for the shift in travel patterns to/from Oak-Land Middle School, site trips were estimated throughout the network and modified to align with the new hours of operations. Given the staggered start/end times, four (4) separate peak hours were analyzed as part of this study to align with the new school times. It should be noted that these peak hours, which are also summarized in Table 5, slightly overlap with each other, however, in general the two (2) schools are staggered enough to minimize compounding impacts. Note the p.m. peak hour is based on the adjacent roadway network and is expected to remain from 4:00 to 5:00 p.m. Table 5. School Time Changes School School Times School Peak Hours Analyzed Current Future (2026) Oak-Land Middle School 7:50 – 2:20 pm 8:35 – 3:05 pm 7:45 -8:45 am 2:30-3:30 pm Lake Elmo Elementary 8:45 – 3:15 pm 7:45 – 2:15 pm 7:00 -8:00 am 1:45-2:45 pm Background Traffic Growth To account for general background growth in the area, a growth rate of one and three quarters (1.75) percent was applied to the existing peak hour traffic volumes to develop year 2026 background traffic forecasts. This growth rate was developed using a combination of historical average daily traffic (ADT) volumes from surrounding roadways publish by MnDOT, traffic forecasts from both the City of Lake Elmo and Washington County Comprehensive Plans, and engineering judgment. It should be noted that there are several development opportunities and potential roadway connections south of the school sites, however, based on discussions with the project team the general background growth rate is expected to account for this development potential from a traffic perspective. Trip Generation – Oak-Land Middle School To account for the traffic operations associated with the enrollment changes expected at Oak-Land Middle School, trip generation estimates were developed. The trip generation estimates, shown in Table 6, were developed using the existing trip rates based on the data collected at the site access locations (highlighted in gray).

Therefore, the school site trips were proportionally increased to account for the change in trips associated with the proposed enrollment increases. Trip Generation – Lake Elmo Elementary School To identify the traffic operations with the proposed elementary school, trip generation estimates for the school arrival (7:00 to 8:00 a.m.), school departure (1:45 to 2:45 p.m.), and p.m. peak hours (4:00 to 5:00 p.m.), as well as a daily basis were developed. The trip generation estimates, shown in Table 7, were developed using the ITE Trip Generation Manual, 11th Edition. Note that the trip generation was developed for the maximum enrollment of the school to provide a conservative estimate. Table 7.

Peak Hour Daily Trips In Out In Out In Out Elementary School (520) 1,100 446 379 228 267 81 95 2,497 Results of the trip generation estimate indicate that the proposed new Lake Elmo Elementary School is expected to generate approximately 825 school arrival peak hour, 495 school departure peak hour, 176 p.m. peak hour, and 2,497 daily trips. Trips were distributed throughout the study area based on the directional distribution shown in Figure 9, which was developed based on enrollment information provided by the school district, existing travel patterns, and engineering judgement. Traffic Forecast Summary Based on the traffic forecast approach described within this study, peak hour traffic forecasts were developed for year 2026 build conditions, which is illustrated in Figures 10. The year 2026 build conditions incorporate adjustments for school hours at Oak-Land Middle School, general background growth, and additional trips generated by the new elementary school and middle school expansion. Figure 10 illustrates the peak volumes during the busiest periods, showing the peak hour volumes for each respective school at their primary study intersections. The year 2026 build traffic forecasts for all four (4) school peak periods are shown in the Appendix.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 22 Year 2026 Build Conditions To understand how the study intersections will accommodate the year 2026 build traffic forecasts, an intersection capacity analysis was completed using Synchro/SimTraffic software. The following information summarizes the year 2026 build conditions. Assumptions The following assumptions were included as part of the intersection capacity analysis: • While operational issues were identified at the 10th Street/Keats Avenue intersection under existing conditions, the intersection was assumed to remain all-way stop control under the build conditions analysis. It should be noted that roundabout evaluation and preliminary design is programmed for 2027 based on the Washington County 2024-2028 Capital Improvement Plan. • It should be noted that the analysis assumes there is adequate parent pick-up/drop-off storage provided on-site. The required storage for parent pick-up/drop-offs and potential impacts of inadequate storage are discussed within the site plan review section. • While not shown in the preliminary site plan, an eastbound left-turn lane was assumed at the 10th Street/Main School Access for the new Lake Elmo Elementary School. • The operations analysis represents the busiest hour for each respective school at their primary study intersections. Operations for all four (4) school peak periods are shown in the Appendix. Year 2026 Build Conditions Results of the year 2026 build conditions intersection capacity analysis are shown in Table 8.

Note the p.m. peak hour is based on the adjacent roadway network.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 23 The following information summarizes the operational and/or queuing issues identified as part of the year of opening (i.e. 2026 build) intersection capacity analysis. Note the following section summarizes the percentage of trips contributed to the roadway network by the school developments. 10th Street/Keats Avenue: o The intersection is expected to be overcapacity during the p.m. peak hour, with overall average delays of over three (3) minutes and maximum eastbound queues of 1/2-mile. o As mentioned previously, this intersection is programmed within the Washington County 2024-2028 Capital Improvement Plan for roundabout evaluation/preliminary design in 2027. o Recommendation: The County should execute their CIP and construct a roundabout at the intersection to improve operations and safety. 10th Street/Lake Elmo Avenue:
o The intersection is expected to operate at an unacceptable LOS E/F during the a.m., school departure, and p.m. peak hours. Eastbound queues are expected to be over 600 feet during all three peak hours, and westbound queues are expected to be over 1,500 feet during the a.m. peak hour. o As mentioned previously, while the intersection is below the average crash rate, there have been eight (8) crashes in the last five (5) years that involved vehicles running the stop sign or failing to yield right-of-way. o Recommendation: The County should consider constructing a traffic signal or roundabout at the intersection to improve operations and better delineate right-of-way. 10th Street/Lake Elmo Elementary Main School Access:
o The southbound approach (i.e. elementary school exit) operates at LOS F and is expected to have queues of 500 to 1,200 feet (25 to 60 vehicles) during the peak 30-minute windows before and after school start and end times. o Approximately 250 vehicles are expected to make a southbound left-turn movement during the a.m. peak hour, which presents a safety concern given the peak characteristics associated with the school, and the high-speeds (i.e. 55-mph) of the adjacent roadway network. In addition, gaps along 10th Street are expected to be limited, and drivers may accept smaller gaps and make more aggressive movements, which could increase the risk of a potential crash. o Recommendation: Construct a traffic signal or roundabout at the intersection to improve operations and safety. Other options were considered, such as employing traffic control officers, restricting left-turns, or implementing staggered pick-up/drop-off schedules. However, high speeds on the roadway pose a safety concern for traffic control officers. Implementing access restrictions would force vehicles to travel three quarters of a mile to the 10th
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 24 Street/Keats Avenue intersection to reroute their travel patterns. Additionally, while staggered pick-up/drop-off schedules could help alleviate some operational challenges, they may inconvenience parents with multiple students and are unlikely to fully resolve the safety and operational concerns. 10th Street/Lake Elmo Elementary Bus Access:
o During school arrival and departure peak hours, an estimated 16 to 18 buses are anticipated to access the site from the south, likely within a similar time window. o Recommendation: While not needed from an operations perspective, given the high speeds (i.e. 55-mph) of the roadway, a northbound left-turn lane is recommended at the school’s bus access from a safety perspective.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 25 Trip Proportional Share Based on the year 2026 build conditions analysis, intersection improvements were identified at the 10th Street/Lake Elmo Avenue intersection. The improvements are triggered based on a combination of background traffic and the maximum enrollment of the elementary school. It should be noted that operational issues were identified at the intersection during the p.m. peak hour under existing conditions. Therefore, to identify the number of trips the proposed elementary school contributes to the intersection, a trip proportional share analysis was conducted. The intersection is currently an all-way stop control, therefore, all movements conflict with each other and contribute to the overall operations of the intersection. The trip proportional share, which is shown in Table 9, was developed by taking the expected elementary site trips entering the intersection and dividing them by the total number of entering vehicles under the year 2026 build conditions. The review included daily trips as well as each of the three peak hours analyzed (i.e. a.m., school departure, and p.m. peak hour) given issues were identified under all peak hour scenarios. Note that the proportional share was primarily focused on the Lake Elmo Elementary School trips, as the school times are largely staggered from each other and the increase in trips from Oak-Land Middle School during the p.m. peak hour is expected to be minimal. The resultant proportional share of trips that the proposed elementary school contributes to the intersection ranges from seven (7) to 35 percent. Table 9. 10th Street/Lake Elmo Avenue - Trip Proportional Share (2026 Build) Entering Volumes A.M. Peak Hour School Departure Peak Hour P.M.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 27 Parent Pick-up/Drop-off Storage A review of the existing and proposed parent pick-up/drop-off storage was completed to identify any issues and recommend potential improvements to limit any impacts to the adjacent roadway network. Oak-Land Middle School As mentioned previously, field observations were performed at the Oak-Land Middle School to identify any access, circulation, and/or parent pick-up/drop-off issues. Observations indicated that internal queueing extended onto Manning Avenue but generally remained within the turn lane storage at the Manning Avenue/Oak-Land Middle School south access intersection. From the main building access, there is approximately 750 feet of single-lane internal queueing storage provided on-site, and approximately 1,200 feet of queues were observed. Projecting forward with the anticipated enrollment increases, approximately 375 feet of additional storage may be required in the future to accommodate increased demand. With the future enrollment, parent pick-up/drop-off queues are expected to extend beyond turn lanes, which may cause friction and additional conflict points along Manning Avenue. Therefore, the following considerations are provided to help increase vehicular storage on-site, which are summarized below and illustrated in Figure 12. It should be noted that there is limited flexibility to improve on-site storage for the site given the existing building footprint/access and the Manning Avenue intersection location. 1. Consider implementing a dual-lane entry within the parking lot to provide an additional 500 feet of on-site storage. This configuration allows vehicles to queue in two lanes before merging into a single lane prior to the parent pick-up/drop-off area. The strategy could be accomplished through the use of daily cones, signage, pavement markings, and/or direct communication with parents. It is important to note that this strategy will utilize the full width of the drive isle, which may limit parking and/or maneuvering the parking lot for staff and other users. Additionally, the merge point may present a learning curve for some parents, and initial implementation may require support from the school resource officer. Note this strategy will not alleviate queueing onto Manning Avenue but is expected to maintain queueing within the turn lane storage, similar to what was observed under existing conditions. 2. If feasible, consider providing an additional building access for students on the south side of the building. During observations, it was noted that despite signage, parents did not pull up past the main school entrance, resulting in 170 feet of on-site queuing storage being underutilized. Introducing a south-side access point would encourage parents to utilize this additional storage effectively. 3. Other strategies, such as implementing staggered pick-up/drop-off times for different grades or classes could be considered if issues arise.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 29 Lake Elmo Elementary School The proposed elementary school layout includes a one-way parent pick-up/drop-off, with two lanes of queueing storage provided near the school’s main entrance. Based on the preliminary site plan, there is expected to be approximately 2,100 feet of internal queueing storage provided within the parent pick-up/drop-off lane. Based on recent (i.e. 2022 to 2024) queueing studies completed by SRF at multiple elementary schools in/around the metro (including the existing Lake Elmo Elementary School), the expected storage needed for an enrollment of 1,100 students is approximately 2,400 feet. Note this storage represents the school pick-up timeframe, which is often longer than the morning drop-off, as several parents often arrive early and wait for the school release. Comparing the expected storage needed at the proposed elementary school under the max enrollment with the preliminary site plan indicates that there is a potential deficit of approximately 300 feet of storage. This deficit may result in queues along 10th Street to block through traffic, which could cause safety and operational issues. Therefore, the following site plan considerations are provided to help increase vehicular storage on-site and improve internal operations/site circulation, which are summarized below and illustrated in Figure 13. 1. Consider extending the dual-lane storage to just east of the internal intersection to provide an additional 300 feet of on-site vehicular storage. While a dual-lane pick-up/drop-off operation could be considered, it requires significant staffing for successful implementation. The purpose of the dual-lanes in this configuration is to increase the capacity for stacking vehicles on-site before merging them into a standard single-lane pick-up/drop-off area. a. Provide adequate signage and striping to inform parents to form two lanes during school pick-up/drop-offs and merge to one lane near the designated parent pick-up/drop-off area. Note that based on other school observations, this may only be needed during school pick-ups when parents arrive early and wait for the school release. As mentioned previously, the merge point may present a learning curve for some parents, and initial implementation may require support from school staff. 2. Consider reconfiguring or redesigning the parking lot to minimize access points near the parent pick-up/drop-off outlet. This adjustment aims to decrease conflict points, designate right-of-way to reduce driver confusion, and improve circulation.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 31 Pedestrian/Bicycle Considerations Note the existing pedestrian/bicycle facility network is discussed in the existing conditions section and previously shown in Figure 3. While nearby local neighborhood developments incorporate internal pedestrian/bicycle facilities, the adjacent highways generally lack off-street facilities and pedestrian crossings. The proximity of the two (2) schools to these high-speed county highways presents a challenge in balancing pedestrian connectivity with safety concerns. Enhancing pedestrian access is important for ensuring school accessibility, yet the high-speed nature of the adjacent roadways raises safety considerations. Therefore, the following pedestrian/bicycle considerations are offered, which are also illustrated in Figure 14. It should be noted that there may be several feasibility challenges with the provided considerations, therefore, further discussion should occur with area stakeholders to determine what pedestrian/bicycle facilities options could/should be implemented. 1. Extend the existing trail along 10th Street (trail starts at Palmer Drive but terminates approximately 150 feet to the east) to connect to the Manning Avenue/10th Street intersection. This connection provides Oak-Land Middle School users the ability to walk to/from the neighborhood development along Palmer Drive. 2. Guide future development to include a trail connection from Oak-Land Middle School to the neighborhood to the west. The neighborhood comprises of approximately five (5) percent of the middle school’s current enrollment and is within a short walking distance, averaging less than 3/4 mile. a. As mentioned previously, there are upcoming plans to extend 5th Street to Manning Avenue, with off-street trails along the roadway and anticipated residential developments nearby. Therefore, this trail connection could potentially facilitate a future trail connection to the extended 5th Street if/when it gets extended. 3. Similar to consideration #2, there are residential neighborhoods nearby where students could potentially walk or bike if safe facilities were provided. This consideration involves establishing a pedestrian/bicycle connection to/from the neighborhoods to the southeast, east, and northeast of the proposed elementary school. The proposed facilities would cross the adjacent highways at the current all-way stop controlled intersection of Lake Elmo Avenue/10th Street, with potential improvements to a traffic signal or roundabout. Given the roadway speeds, additional support from parents or staff may be desired at the crossing. Nevertheless, this offers another accessibility option that could help alleviate vehicular traffic. 4. The Washington County Bicycle and Pedestrian Plan (2021) identifies future off-road pedestrian/bicycle facilities along 10th Street (CSAH 10) and Manning Avenue (CSAH 15). Note both corridors are designated as “high priority” within the plan and would connect the proposed facilities outlined above. While not identified in the plan, an off-street facility could be considered along Lake Elmo Avenue could provide access to the residential development along 5th Street. a. Note Washington County is planning to reconstruct Manning Avenue from 10th Street to 30th Street to provide center left-turn lanes at key locations. As part of the project, off-street pedestrian/bicycle facilities could be considered.

New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 33 Summary and Conclusions SRF has completed a transportation study for the new Lake Elmo Elementary School and the additions to Oak-Land Middle School in the City of Lake Elmo, MN. The main objectives of the transportation study were to review existing operations within the study area, evaluate transportation impacts to the adjacent roadway network based on the new elementary school and additions to the middle school, and recommend any necessary improvements to provide safe and efficient operations for all modes of transportation. Key findings of the transportation study are summarized below: 1) Existing Conditions: a. Pedestrian/Bicycle Facilities: Existing pedestrian/bicycle facilities were assessed, revealing gaps and safety challenges, particularly due to the high-speed roadways surrounding the schools. b. Safety Analysis: A review of crash data identified patterns and highlighted intersections with higher crash rates, however, none of the study intersections have a crash rate over the critical rate, indicating that no study intersections have a statistically significant crash problem. c. School Observations: Field observations were conducted at both the Oak-Land Middle School and former Lake Elmo Elementary School to identify travel patterns, pick-up/drop-off queues, and other site-specific issues. i. Parent pick-up/drop-off queues were observed at Oak-Land Middle School to extend onto Manning Avenue for short durations (i.e. 10-minutes) during the school arrival and departure peak hours. d. Traffic Operations: Existing operational issues were identified at the following study intersections. All other study intersections are expected to operate at an acceptable LOS D or better during peak periods. i. 10th Street/Keats Avenue: Overall intersection operates at LOS F during the p.m. peak hour. ii. 10th Street/Lake Elmo Avenue: Eastbound approach operates at LOS E during p.m. peak hour. 2) Traffic Forecasts: a. Background Growth: A 1.75 percent annual growth rate was applied to existing peak hour traffic volumes to forecast 2026 background traffic. b. Lake Elmo Elementary Trip Generation: The new Lake Elmo Elementary School is expected to generate approximately 825 a.m. peak hour, 495 school departure peak hour, 176 p.m. peak hour, and 2,497 daily trips.
New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 34 c. Oak-Land Middle School Trip Generation: The expected enrollment changes at the Oak-Land Middle School are expected to generate an additional 196 a.m. peak hour, 95 school departure peak hour, 59 p.m. peak hour, and 685 daily trips. 3) Future Operations: a. Year 2026 Build Conditions: The following study intersections were projected to experience unacceptable levels of service during peak hours: i. 10th Street/Keats Avenue ii. 10th Street/Lake Elmo Avenue iii. 10th Street/Lake Elmo Elementary School Main Access b. Trip Proportional Share: Existing issues were identified at the 10th Street/Lake Elmo Avenue intersection. Therefore, a trip generation analysis was conducted to determine the proportion of trips attributable to the proposed elementary school. It is anticipated that the elementary school will contribute seven (7) to 35 percent of the total traffic volume at this intersection. c. Parent Pick-up/Drop-off Storage: Both schools are expected to have a deficit in on-site vehicular storage for parent pick-up/drop-off operations, which may cause impacts to the adjacent roadway network. 4) Recommendations: a. Intersection Improvements: Traffic control improvements (i.e. traffic signal or roundabout) were recommended at the following study intersections to improve operations and safety. In addition, a northbound left-turn lane was recommended at the Lake Elmo Avenue/Lake Elmo Elementary School Bus Access intersection for safety purposes. i. 10th Street/Keats Avenue ii. 10th Street/Lake Elmo Avenue iii. 10th Street/Lake Elmo Elementary School Main Access b. Site Plan Recommendations: Recommendations were provided for both schools to improve internal circulation and expand on-site queuing storage to accommodate the increased vehicular demand expected during peak periods. c. Pedestrian/Bicycle Connectivity: Enhancements were proposed to create safer connections for pedestrians and bicyclists, including trail extensions and new crossings, to promote active transportation.

Lake Elmo, Minnesota
Property Noise Measurement Summary
Veneklasen Project No. 8512-002
Dear Matthew:
Veneklasen Associates, Inc. (Veneklasen) provides the following property acoustical measurement summary and
analysis as compared to the applicable State of Minnesota noise codes for the subject project. The proposed project is
planned due east of the existing Oakdale Gun Club in Lake Elmo, Minnesota. Given that measurements were not
completed during the peak operational time of year for the club, additional acoustical analyses were conducted to
estimate potential increases in measured noise levels for increases in club activities. This report documents our
findings.
Executive Summary
The subject project is proposed to be constructed on a corner lot directly due east, and to share a property line with,
the existing Oakdale Gun Club, both located in Lake Elmo, Minnesota. The intention of this study was to determine
whether existing activities from the gun club as measured at the proposed project property, as well as other planned
outdoor activity areas for the school and at the westernmost portion of the school building, would comply with the
applicable State noise codes.
An acoustical measurement survey was conducted to collect data from gun club activities at various areas of acoustic
sensitivity, as defined by the appropriate codes. This data was analyzed and compared against allowable property
noise level limits and determined to be compliant without additional mitigation.
Further analysis was conducted to evaluate the anticipated noise level increases resulting from increased activity as
well as the effects that higher-caliber firearms have on measured noise levels. These results were also compared to
applicable code requirements and found to be compliant without additional mitigation.
In summary, existing noise levels from the gun club as well as anticipated noise from increased use at busiest time
meet the Code requirements and do not require the Lake Elmo Elementary School to implement any noise mitigation
measures to be compliant with the state noise code requirements.
Noise Criteria
The City of Lake Elmo has no specific criteria for property noise relating to firearms, shooting ranges, or gun clubs. Nor
does it include any explicit prohibition of noise beyond subjective language. In instances such as this, it is appropriate
to defer to the county or state codes.
Typically, this would solely be the Minnesota Pollution Control Agency (MPCA) Chapter 7030 “Noise Pollution
Control”. However, the Minnesota Statutes 2023 Chapter 87A “Shooting Ranges” document has specific criteria that
apply to shooting ranges and the like that explicitly modify the MPCA noise criteria. Both of these criteria are
explained further below.

Section 87A.05 “Noise Standards” of the Minnesota Statutes document states the following:
Allowable noise levels for the operation of a shooting range are the levels determined by replacing the steady
state noise L10 and L50 state standards for each period of time within each noise area’s classification with a
single Leq(h) standard for impulsive noise that is two dBA lower than that of the L10 level for steady state
noise. The noise level shall be measured outside of the range property at the location of the receiver’s activity
according to the Minnesota Rules, parts 7030.0010 to 7030.0080, as in effect on May 28, 2005. For purposes
of this section, “Leq(h)” means the energy level that is equivalent to a steady state level that contains the
same amount of energy as the time varying sound level for a 60 -minute time period.
Per the MPCA chapter on noise control, an elementary school would be classified as a Noise Area Classification 1 ,
which has the strictest noise limits in this document and also classifies property types such as residences, places of
worship, etc. Section 7030.0040 “Noise Standards” provides a table of allowable noise levels per noise metric (L10 or
L50), time of day, and Noise Area Classification. Table is summarized below.
Table 1. MPCA Property Noise Standards
Noise Area

Daytime Nighttime
L50 L10 L50 L10
1 60 65 50 55
2 65 70 65 70
3 75 80 75 80
Per discussions with the gun club management, the club closes for members at sundown. Daytime hours, per the
MPCA, are defined as the hours between 7AM and 10PM. Based on the Noise Classification Area and the daytime
operation, the standard MPCA criteria would be:
1. L50 limit of 60 dBA and
2. L10 limit of 65 dBA.
3. However, per Section 87A.05, which specifically addresses a shooting range, these criteria are substituted for
a single hourly equivalent (average) sound pressure level of 63 dBA.
Section 87A.04(a) “Mitigation Area” of the Minnesota Statutes document states the following:
Except for those uses, developments, and structures in existence or for which approval has been granted by
October 1, 2005, or as provided in paragraph (b), no change in use, new development, or construction of a
structure shall be approved for any portion of property within 750 feet of the perimeter property line of an
outdoor shooting range if the change in use, development, or construction would cause an outdoor shooting
range in compliance with this chapter to become out of compliance.
This states that, given the school property has portions within 750 feet of the existing gun club property line, if gun
club activities would exceed the 63 dBA limit discussed above, it is the responsibility of the Client to provide acoustic
mitigation to comply. Per Section 87A.05, areas that must comply with this noise limit include areas of outdoor activity
and the school building itself.
Acoustical Measurement Summary
An acoustic measurement survey was conducted to evaluate the existing impacts of gun club activities on the property
line, as well as other proposed areas of outdoor activity per the applicable State code. These results were then
compared to the allowable noise limit to determine whether additional steps towards acoustic mitigation were
necessary.
Beginning on the 4th of July and going until the fall, the Oakdale Gun Club opens their club to the public on weekends.
It is limited to membership only on weekdays in this period of time. It is understood that, during this period of time,
occupancy increases on weekends because the club hosts both the public as well as its members. Therefore, it was

Veneklasen’s goal to conduct acoustic measurements over some of these July weekends to capture both “membership
only” days as well as weekends, which may have higher occupancy.
Veneklasen visited the site on Monday July 8, 2024 and set up four (4) noise monitors on the proposed project site to
capture gun club activity noise. Acoustic data was captured over two (2) separate weekends and several weekdays.
Per the code criteria, noise levels were evaluated by hour-long segments. Sounds not attributable to gun club activities
(e.g., documented weather events using the Weather Underground website) were omitted from the analysis.
Table 2 and Figure 1 below show a summary of the collected noise data attributable to gun club activities as well as an
aerial satellite image of the measurement locations. L1 was taken at the property line, L2 was taken at the nearest
location of proposed outdoor school activities, L3 is the approximate edge of the 750-foot mitigation area discussed in
the previous section, and L4 is the northwesternmost corner of the proposed school building.

Note that often levels from L3 and L4 are louder than L1 and L2 despite being further away from the gun club. Our
analysis of gun club activity noise has determined that often gun fire noise levels are equal to, or sometimes below,
the existing ambient noise levels, which are dictated by nearby traffic noise. Measurement positions L3 and L4 are

closer to the nearby roadways and the average hourly levels are therefore generally louder unless influenced by
higher amounts of gunfire activity. Note that the maximum hourly level at L1 is louder at L1 than all other positions
due to gun fire activity.
Acoustic Modelling
To verify the accuracy of acoustic measurements at the positions noted above, Veneklasen created an acoustic model
of the gun club and proposed school property. The 2023 version of the SoftNoise Predictor acoustic modelling
software was used to build the noise propagation model, specifically using the ISO 9613 noise calculation method. This
software allows the incorporation of geographical conditions across both sites, atmospheric affects, effects of existing
structures, and other attributes that affect how sound levels change as they propagate from the gun club to the
proposed school properties.
Once all four noise monitors, as discussed above, were running, Veneklasen had club members conduct several test
shots at each of the five shooting bays and conducted short-duration calibration measurements within 15-feet of each
of these shooting locations. These measurements were used to show the accuracy of the acoustic model discussed
above to verify that the terrain, foliage, atmospheric conditions, etc. were all modeled appropriately such that the
model represented real-world measurement conditions. The maximum deviation between modelled analysis results
versus measured results was 0.9 decibels at the L4 position, which is the furthest position away from the sound source
and well within the acceptable margin of error for an acoustic model.
As noted above, acoustical measurements took place in July of 2024 when the gun club is only open to the public on
weekends. However, during the months of October and November, the club is open to the public seven days a week.
Per conversations with gun club ownership, these months are the most populus and generally when they have the
highest patronage. Once a suitable acoustic model was constructed, it was pertinent to evaluate anticipated noise
level changes based on increased occupancy from summer to fall. This includes both the effects of increased number
of people as well as higher caliber firearms. Acoustic models were created for each condition.
Increased Occupancy
The gun club does not track number of rounds fired per day. They do, however, track the number of patrons who
attend per day and were able to provide Veneklasen with occupancy data for July of 2023, October through November
of 2023, and July of 2024. Veneklasen utilized a formula to calculate the anticipated change in measured sound level
based on changes in occupancy from summer to fall. This formula format is a logarithmic change formula used often in
acoustics for other applications (e.g., changes in traffic noise):
𝛥[𝑐𝐵] =10 log10
𝑜𝑐𝑐𝑒𝑎𝑙𝑙
𝑜𝑐𝑐𝑟𝑢𝑙𝑙𝑒𝑟
To model the increases in measured noise level, Veneklasen input the occupancy data collected from July of 2024 and
the fall of 2023 into the formula above. Figure 2 shows predicted noise with increased occupancy in the fall at the
same measurement locations shown in Figure 1. Numeric results below are shown in one hour dBA values with a
maximum value of 60dBA, which is below the allowable 63dBA criterion.

Figure 2. Increased Fall-Time Occupancy Noise Model
Given that this method is primarily used for constant sound sources (e.g., free flowing traffic or mechanical
equipment), using it for an intermittent sound source like gunfire will likely result in an overestimation of increased
noise. When summing constant and equal sound sources, the two will always overlap because they are consistently
running and therefore double; when summing intermittent sound sources, whether or not the overall acoustic
pressure doubles or is less than double depends on whether the intermittent events line up in time or not.
Additionally, occupancy data provided to Veneklasen is highly variable when comparing July of 2023 to July of 2024.
On average, weekends in July of 2023 were ten persons lower than weekends in July of 2024. Given that the highest
occupancy weekend day in either year during this month was 38 people, this is a statistically significant swing.
Therefore, Veneklasen has used the 90th percentile of occupancy data for July of 2024 and for fall of 2023 to evaluate
a case where a large number of patrons happen to v isit the club on a particular day. All occupancy data provided to
Veneklasen by gun club ownership can be found in the appendix.
High-Caliber Firearms
In careful analysis of the measurement data, it was observed that there were instances where the hourly noise level
on a particular day would be substantially higher than the other measured hourly levels on that same day. It was
found that these were due to louder individual gunshot events occurring within said hour (or hours) as compared to
other hours. These were uncommon in the measured data. As mentioned previously, gun club management provided
a demonstration for Veneklasen at each of the firing bays so that short-duration acoustic measurements could be
conducted and compared to the noise monitoring positions in order to calibrate an acoustical model. One of these
was a 45-caliber firearm.

To model the case where patrons of all shooting bays are using a high caliber rifle, Veneklasen modelled noise to the
proposed school property in the instance where a 45-caliber firearm is being used at each of the five shooting bays
simultaneously. This is representative of a shooting competition event being held at the club. Numeric results below
are shown in one hour dBA values with a maximum value of 62 dBA, which is below the allowable 63 dBA criterion.
Note, this model is conservative for a similar reason the above model is because shooters in all five bays will not be
firing simultaneously and will not all fire the same number of rounds so what is presented is the most conservative
representation of use. It is also worth noting that the gun club has a 50 -caliber firearm limit.
Figure 3. Five Simultaneous High-Caliber Firearm Modelled Noise Levels
Summary
Veneklasen conducted acoustic measurements of firearm noise from the Oakdale Gun Club as measured on the
proposed project school site to determine whether noise levels exceeded allowable MPCA criteria and would trigger
the proposed project to implement noise control measures. The allowable noise threshold was 63dBA as measured
within one (1) hour at any location on the school property where activity would take place.
Acoustic measurements at four (4) key locations were taken in July of 2023. The results of these measurements
showed that existing noise levels are compliant with MPCA criteria. However, it was communicated to Veneklasen that
occupancy, and likely noise, was greater during the months of October and November. Therefore, Veneklasen
completed additional calculations to model different higher-noise operating conditions of the gun club and verify
these would also be code compliant.

Veneklasen modelled both an increase in gun club occupancy as well as increased usage of high -caliber firearms. Both
of these acoustic models also showed noise levels in compliance with MCPA criteria. It should be noted that, for
reasons discussed above, these calculated models are conservative and likely overestimated noise levels.
Therefore, no acoustic mitigation measures are required to comply with state noise codes.
If you have any questions, please do not hesitate to call.

MEMORANDUM
Date: September 23, 2024
To: Sophia Jensen, City Planner Re: ISD 834 Lake Elmo Elementary School
Cc: Nathan Fuerst, Planning Consultant PID 26‐029‐21‐44‐0001
Marty Powers, Public Works Director Minor Subdivision and CUP
Chad Isakson, PE, Assistant City Engineer
From: Jack Griffin, PE, City Engineer
Engineering has reviewed the ISD 834 Lake Elmo Elementary School Site Plans received August 26, 2024 as part of
their Minor Subdivision and CUP applications. The new school is proposed to be located at the corner of Lake
Elmo Avenue (CSAH 17) and 10 Street (CSAH 10). The review consisted of the following documentation:
Plat: 10th and Lake Elmo School Addition.
Preliminary Plat and Plans dated August 23, 2024: C000, C001, C002, C050, C100‐C105; C200‐C205; C300‐
C305; C400‐C405; C500‐505.
Stormwater Management Report dated August 23, 2024.
Draft Geotechnical Report dated June 26, 2024.
Traffic Study dated August 1, 2024.
FINAL PLAT: 10TH AND LAKE ELMO SCHOOL ADDITION
1. The Final Plat shall not be recorded until the City Engineer approves the Final Construction Plans.
2. County Roadway Right‐of‐way Dedication. Right‐of‐way dedication has been shown on the Plat along both
Lake Elmo Avenue (CSAH 17) and 10th Street North (CSAH 10) to provide a total of 75‐feet from
referenced section line. The right‐of‐way dedication must be reviewed and verified by Washington County
prior to recording a Final Plat to ensure the right‐of‐way dedication is sufficient for future County roadway
improvements, including potentially a future roundabout complete with pedestrian facilities.
Additional right‐of‐way dedication appears to be needed at the northwest corner of Lake Elmo
Avenue (CSAH 17) and 10th Street North (CSAH 10) to accommodate a site‐triangle similar to the
northeast and southeast corners.
3. All easements as required by the City Engineer and Public Works Director shall be documented on the
Final Plat prior to the release of the Final Plat for recording. Easement revisions may be necessary to the
Final Plat as the Construction Plans are reviewed and finalized. All easement areas must be free from all
encroachments other than those approved by the City Engineer and upon execution of an easement
encroachment agreement. Prohibited encroachments include, but are not limited to trees, structures,
landscaping, fences, retaining walls, storm sewer running parallel with the easement, stormwater basins
and BMPs, and grading that exceeds 4:1.
4. Dedicated drainage and utility easements, minimum 10‐feet wide, are required along all public roadway
frontage. Easements along public roadways, including Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH
10), have been shown on the Final Plat as required.
Site and grading plan revisions will be necessary to remove grading and BMP encroachments to
preserve the use of these easements for small/dry utility installation. Grading within the easement
areas must be revised and the plans clearly labeled to be a 4:1 maximum slope.

Chad Isakson, P.E. 651.300.4285
PAGE 2 of 4
5. Dedicated utility easements are required over all public watermain as determined by the City Engineer
and Public Works Director. Easements must be a minimum width of 30‐feet centered over all public
watermain and each hydrant. Dedicated utility easements have been shown on the Final Plat. Revisions
may be necessary as the Construction Plans are reviewed and finalized.
6. Drainage and utility easements are required over all stormwater BMPs, including the 100‐year high water
level areas, maintenance access roadways to a public right‐of‐way, maintenance benches, and over all
emergency overflow locations and pathways. Stormwater management easements are shown on the Final
Plat, but must be revised to incorporate all required elements as listed above. Easement revisions are
necessary such that the Final Plat easements are consistent with the easements shown on the site and
grading plans. Additional revisions may be necessary as the Construction Plans are reviewed and finalized.
7. The storm water management facilities will remain privately owned and maintained. A Storm Water
Maintenance and Easement Agreement in the City’s standard form of agreement must be executed and
recorded with the Final Plat for all privately owned stormwater facilities.
8. All off‐site permanent and temporary easements, if necessary to construct the proposed site
improvements, must be acquired and provided to the City prior to the approval of the Final Construction
Plans. Each easement, if needed, must be provided in the City’s standard form of easement agreement.
TRANSPORTATION IMPROVMENTS, ACCESS AND COLLECTOR STREETS
1. Access Management. The proposed access locations along both Lake Elmo Avenue (CSAH 17) and 10th
Street (CSAH 10) must be approved by Washington County.
2. Turn Lane Improvements. As part of the site improvements, dedicated right and left turn lanes must be
constructed along Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10) at both access locations. Turn
lanes must be constructed meeting Washington County standards
3. Intersection Control Improvements. Traffic Control Improvements must be included as part of the site
improvements for the opening of the school as recommended by Washington County. A traffic signal is
required at the new access location along 10th Street North (CSAH 10), complete with crosswalks. A
temporary wood‐pole traffic signal, or alternate traffic control improvement approved by Washington
County, is required at the intersection of Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10),
complete with crosswalks.
4. Emergency Service Access. Emergency vehicle access to and throughout the site must be reviewed and
approved by the Lake Elmo Fire Department.
5. Bituminous Trails. The site improvements include the construction of a bituminous trail along the east and
south sides of the site long Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10). The grading plans
should be revised to eliminate the drainage swale obstruction that will impede any future extension of
the trail to the west along 10th Street (CSAH 10). Consideration should also be given to the provision of
pedestrian connectivity internal to the school property and connection to the County Park Preserve.
STORMWATER MANAGEMENT
1. The site plan is subject to a storm water management plan (SWMP) meeting State, Valley Branch
Watershed District (VBWD) and City rules. Storm water facilities proposed as part of the site plan to meet
State and VBWD permitting requirements must be constructed in accordance to City Engineering Design
Standards dated January 2022, even though the facilities will remain privately owned.
2. The stormwater management mitigation must be provided for all required site improvements, including
the County roadway and intersection improvements, County roadway turn lanes, and all bituminous trails.
3. In addition, it should be condition of the minor subdivision approval that the stormwater management
BMPs be oversized to accommodate the future County roadway improvements to be constructed by the
County at a future date. The stormwater BMP oversizing must address the additional proposed
impervious surface areas as provided by Washington County.
4. All stormwater facilities and BMPs will be privately owned and maintained by the school district. The
school district will be required to provide a Stormwater Maintenance and Easement Agreement in
accordance with the City’s standard form of agreement.
PAGE 3 of 4
5. All storm water basins must be placed in easements in accordance with the Stormwater Maintenance and
Easement Agreement. The easements must fully incorporate the 100‐year high water level areas, 10‐foot
maintenance bench, maintenance access roadways to a public right‐of‐way, and over all emergency
overflow locations and pathways.
6. The SWMP will be required to verify that rate control and volume control requirements are met for all
points of discharge from the site. The existing and proposed drainage exhibits must clearly show and label
all points of discharge from the site, including any required public improvements and turn lanes. The
SWMP rate control tables must reference each discharge location independently and combined.
7. Overland emergency overflows or outlets will be required as part of the site and grading plans.
8. All infiltration basins shall be sized using design infiltration rates based on actual soil borings obtained
from within the basin footprint at the proposed basin bottom elevation. Soil borings must be taken for
each infiltration basin in the number and to the depths required by the VBWD and City design standards.
Soil boring information submitted to date remains insufficient.
9. All wetlands and wetland buffers must be delineated and protected by easement.
10. Minimum floor elevations must be at least 2 feet higher than the adjacent 100‐year HWL elevation. Also,
all low opening elevations for all buildings must be at least 1‐ft higher than any adjacent emergency
overflow elevation (EOF). All building low floor and low opening elevations must be clearly labeled on the
grading plans.
11. All localized low points (catch basins) and low areas (land locked basins) must be protected within a
drainage easement up to the 100‐year high‐water level. The grading plans must be revised to label and
clarify the purpose of all low areas.
12. The grading plans must label all steep slope areas with notations indicating the maximum allowable
grading slopes.
13. The grading plans must label all basin maintenance access roadways, label the maximum slope as 10%,
and label the maintenance roadway width as 20‐feet.
MUNICIPAL WATER SUPPLY
1. Connection to the municipal water system is available to the existing trunk watermain running along Lake
Elmo Avenue (CSAH 17). The applicant will be responsible for connecting to the existing 16‐inch trunk
watermain along Lake Elmo Avenue (CSAH 17) in two locations to create a looped watermain network
around the new school. A minimum 8‐inch ductile iron watermain shall be extended internal to the site
and throughout the property as necessary to provide connection to all proposed uses.
2. The project will require the placement of fire hydrants and water system valves internal to the site as
determined by the Lake Elmo Public Works Director and Fire Department. The site plans show the
watermain extension, hydrant locations and system valves generally consistent with City requirements.
Revisions may be necessary as the Construction Plans are finalized.
3. Minimum 30‐foot easements centered over the pipe/hydrant have been shown on the plans as required.
4. No watermain oversizing is anticipated as part of this Project.
SANITARY SEWER SYSTEM
1. A Comprehensive Plan Amendment has been approved to expand the Municipal Urban Service Area
(MUSA) for the property. Therefore, the extension of public sanitary sewer service will be required to
serve the new elementary school.
2. The applicant will be required to construct a privately owned and maintained sanitary lift station on the
district property and extend a private forcemain to a designated connection point to be located on the
northeast corner of Lake Elmo Avenue (CSAH 17) and 10th Street (CSAH 10). The private forcemain will be
combined with a new public forcemain to be installed by the City and extended south along Lake Elmo
Avenue (CSAH 17) to an existing trunk sanitary sewer at 5th Street.
3. The new school sewer service would discharge by gravity to the new lift station.
4. Plan revisions are required for the private lift station facility to ensure that the facility is fully located on
district property and that the maintenance access is internal to the school property, fully outside all
required right‐of‐way dedication.
PAGE 4 of 4
5. It is anticipated that the sanitary sewer improvements will be partially constructed though a public
improvement project with both the private and public improvements to be paid by the District.
FINAL CONSTRUCTION PLANS & SPECIFICATIONS
1. Final Construction Plans and Specifications must be prepared and submitted for City review and approval.
The plans and specifications must be in accordance with the City Engineering Design Standards Manual
dated January 2022, using City standard details, plan notes and specifications and meeting City
Engineering Design Guidelines, unless approved otherwise by the City Engineer.
2. No construction on the Project may begin until the applicant has received City Engineer approval for the
Final Construction Plans; the applicant has obtained and submitted to the City all applicable permits,
easements and permissions needed for the project; and a preconstruction meeting has been held by the
City’s engineering department.
3. Existing Conditions Plans C100‐C105. Revise plans to include all required information and labeling to fully
depict the existing site conditions. In particular, the existing condition information is insufficient along the
existing roadway corridors.
4. Site Plans C200‐C205. Revise the site plans to include all required transportation improvements including
safe pedestrian crossing and intersection controls as required by Washington County.
5. Grading Plans C300‐C305. Revise the grading plans to eliminate all easement encroachments along Lake
Elmo Avenue (CSAH 17) and 10th Street (CSAH 10). Revise the grading plans to provide all required
stormwater BMP design information and labels.
6. Utility Plans C400‐C405. Relocate the proposed sanitary lift station to be outside the right‐of‐way sight
triangle and revise the lift station maintenance access to be internal to the site. Label all utilities as public
or private owned and maintained. Provide more design details for all work within the public right‐of‐way.

TREE PRESERVATION PLAN: 105. 12. 470
• A tree preservation plan will need to be submitted that meets code, including, but not limited to:
o The applicant has submitted supplementary information that supports the granting of a variance
that would allow them not to mitigate trees planned to be removed that were planted by the
previous landowner. As such; these trees will not be considered in the tree preservation and
mitigation calculations. However, the removal of more than 30% of the naturally occurring
significant tree inches onsite still requires mitigation.
o 1,969 qualifying (naturally occurring) significant inches exist. 590 are allowed to be removed
without mitigation. The plan proposes removing 739 significant inches of qualifying trees, which
leaves 149” that must be mitigated. No credit is to be given for preserving “previous owner
planted” significant inches.
o In order to determine the number and type of mitigation trees required, the applicant must create
a table that breaks out the significant common, coniferous/evergreen, and hardwood deciduous
trees planned to be removed, per 105.12.470 (c) (8). Any inches removed over the allowed 30% will
need to be replaced at the following percentages: common tree species will need to be replaced at
25% of the inches removed and evergreen/hardwood trees need to be replaced at 50% of the
inches removed.

o Revise the last row of the table on sheet L1.000 to remove reference to a credit and instead include
the breakdown of common, evergreen, and deciduous inches to be mitigated and the
corresponding number of required mitigation trees.
o Replace the tree protection detail on sheet L1.000 with the city standard tree protection detail.
LANDSCAPE PLAN: 105.12.480
• A landscape plan as submitted does not currently meet code, and needs to be revised as follows and
resubmitted prior to approval:
o The landscape plan must be revised to include the addition of the appropriate number of
mitigation trees required to meet tree preservation code.
o Additional trees should include enough evergreens to put the proposed trees into compliance with
the code’s tree composition requirements. More than 25% of proposed trees need to be evergreen
and fewer than 15% can be ornamental.
o Provisions for irrigation are required, whether through an irrigation plan, or a commitment to hire
out watering for the duration of the 2-year warranty period.
o Show the location of a topsoil stockpile and provide notes indicating that the quantity of soil shall
be sufficient to cover all landscaped areas at least 4” deep.
o Ensure that per 105.12.480 (b) (7) trees shall be planted ten feet away from utilities including water
and sewer stubs.
o Screening- Requirements of 105.12.480 (f) Screening is required between more intensive and less
intensive land uses- add or adjust spacing of screening trees along northern drive and play area so
that spacing does not exceed 40’.

Lake Elmo Elementary School
Dear Sophia,
Thank you for the opportunity to review and comment on the proposed Lake Elmo Elementary School
application at the intersection of County State Aid Highway 17 (Lake Elmo Avenue) & CSAH 10 (10th
Street). The county thanks the City of Lake Elmo and the Stillwater School District for meeting with the
county to discuss the proposed new school location that meets the community’s needs while also
providing for safe transportation connections. The county will continue coordinating with the district and
city on this proposed school; below are some comments that the County has for the proposal.
As we have shared, the proposed rural location adjacent to two high-speed county highways presents
several significant challenges related to nonmotorized access and traffic safety and operations; these
concerns are identified in the traffic study. By their nature, County Highways manage regional traffic
(vehicular, freight, transit, bicycle, pedestrian, etc.) at higher average speeds. With Washington County
currently the fifth fastest-growing county in the state, containing two of the top ten fastest-growing
cities in the state (Woodbury and Lake Elmo), we would be irresponsible in not planning for the future of
this area. We offer the following comments regarding the new design of the school site and the traffic
study.
1. The site plan indicates right turn lanes at both proposed access points; the county would also
require dedicated left turn lanes as a condition of access permit approval.
2. The traffic study indicates a significant delay for motorists at the intersection of CSAH 10 and
CSAH 17 (overall Level of Service F), with queues extending well beyond the available storage.
Washington County expects that the development team will mitigate these operational and
safety issues prior to school opening. The intersection of CSAH 10 & CSAH 17 is tentatively
scheduled in the County’s draft Capital Improvement Plan for construction of improvements in
2028, with $4M total planned investment. This is a significant investment, largely driven by the
placement of the school at its proposed location. Washington County appreciates the City’s
support in planning for this improvement during the design of the Lake Elmo Elementary School.
3. The traffic study recommends a traffic signal or roundabout at the County Highway 10/Lake Elmo
Elementary School main access. Washington County expects that this will be installed by the
development team without city or county cost contribution as a condition of access approval, and
operational prior to opening of the school.
A great place to live, work and play…today and tomorrow

P: 651-430-6001 | F: 651-430-6017 | TTY: 651-430-6246
www.co.washington.mn.us
Washington County is an equal opportunity organization and employer
4. The traffic study recommends a northbound left turn lane at the County Highway 17 (listed as
10th Street in the traffic study)/Lake Elmo Elementary Bus Access due to high speeds; Washington
County concurs with this recommendation if left-in access is to be provided at this location.
Washington County continues to view this access as unnecessary, as inbound and outbound
buses could be provided safe and efficient access to the county highway system via the controlled
intersection at the proposed 10th Street access. If the developer feels that an access to Lake Elmo
Avenue must be installed, Washington County expects that this intersection will be designed and
constructed as a ¾ access preventing eastbound ‘left-outs’ from the School site and directing all
traffic to turn south. The Oak-Land Middle School has this configuration at its bus-only access to
County Highway 15 as well. Restricting exiting traffic to right turns only helps prevent the
excessive delays that may be experienced by left turns which would in turn generate demands for
an additional traffic signal or roundabout to provide safe left-out access.
5. The traffic study states that “the expected storage needed for an enrollment of 1100 students is
approximately 2400 feet long” but only 2100 feet of storage is provided. Washington County
cannot allow queuing to extend onto County rights-of-way and infrastructure, and will not permit
an access that does not provide for adequate on-site storage at day of opening and under a
future ‘full-build’ condition.
6. The intersection of CSAH 10 & CSAH 19 is in the draft CIP for construction 2029, with $5.25M
total planned investment.
7. Minimizing unnecessary access to county highways allows for turning movements to be
consolidated to locations where improvements such as turn lanes, traffic signals, and
roundabouts can mitigate traffic conflicts. As a condition of access permit approval, the county
may require the removal of other pre-existing access points and may also require the applicant to
mitigate the traffic safety and operational impacts of the proposed new access through the
installation of various highway improvements including turn lanes, traffic signals, or roundabouts
Still haven't heard a compelling reason for this access.
8. School District staff have communicated that busing will be provided for students in
neighborhoods surrounding the new Lake Elmo Elementary, but this appears to conflict with
information provided on the district’s website stating, “Routes are currently being redrawn to
give priority to all students living 2 miles or further from school and others required by law to

to walk, and encouraging walking promotes health and reduces vehicular traffic demands.
Washington County expects that non-motorized access to the school will be prioritized by the
development team and available to students at the day of opening. This will reinforce the public
nature of the amenities proposed for this site.
Given the continued and rapid progress on the project plans we felt it was important to reiterate the
following comments:
While the placement of schools along highways enables convenient vehicle access, these locations also
present safety issues for vehicles and pedestrians that defy easy or effective solutions. Given the ongoing
prevalence of student drop-offs, school sites often generate significant inbound queues that sometimes
extend onto highway shoulders, into turn lanes, and sometimes even obstructing highway through lanes,
with safety repercussions. Providing adequate internal stacking can consume significant amounts of
space but is necessary to prevent congestion from extending onto highways. Experience with school
speed limits and/or flashing lights suggests that they have very limited effectiveness in slowing traffic
down and can cause a large variability of speed, which is itself a safety concern. Even costly solutions
such as traffic signals are often seen as a barrier for pedestrians due to the high vehicle volumes and
less-than-perfect behavior by drivers.
Safe access to the site for students and others who wish to arrive by walking or biking from existing
nearby neighborhoods, both to provide safe walking routes and safe crossing points of the county
highways remains a priority for Washington County Public Works. The school district must consider and
plan for pedestrian infrastructure within walking distance of the school, notwithstanding any current
policies related to bus transportation. The pedestrian routes should connect with nearby neighborhoods,
both existing and planned, and should provide reasonably direct access into the school site itself. A
preliminary assessment suggests that upwards of four miles of new trail would be needed to connect
existing neighborhoods to the school site. Washington County does not have any available funding for
these necessary trail linkages in our 5-year Capital Improvement Plan.
The Washington County 2040 Comprehensive Plan contains access criteria for county roads related to
spacing, sight lines, and availability of local road connections. School sites typically generate significant
traffic volume and queuing; therefore, the County appreciates the School District’s work to complete a
traffic study to better understand the anticipated traffic operations at the proposed access locations and
affected nearby intersections. Washington County access spacing guidelines for minor arterial roads
(both County Highway 17 and County Highway 10) is ¼ of a mile (1,320 feet). Partial reductions in this
spacing may sometimes be considered in favor of other safety aspects, such as optimizing sight distance
or maximizing spacing from other existing intersections.

Access permits will be needed for the construction of new driveway connections within the county right-
of-way, and will require the construction of turn lanes into the site and the provision of adequate
internal stacking space to prevent congestion from extending onto the county highway.
The Washington County Comprehensive Plan indicates that 75 feet of right-of-way from the centerline
should be secured at the time of development along both CSAH 10 and CSAH 17. The city will be
responsible for the costs of future right-of-way acquisition if not secured at the time of development, in
accordance with Washington County Cost Participation Policy #8001 as previously referenced.
A Right-of-Way Permit will be required for any work within the County highway right-of-way as it relates
to the development. As the development progresses, a plan set will be required with the application and
include any grading, culvert installation, water and sewer services, parallel trail development, signage,
and any landscaping and other improvements within the County right of way.
All utility connections to County highway right of way for the development will also require their own
Washington County Right of Way permits. Typically, these utility connection permits are the
responsibility of the utility companies.
The desire for regional stormwater remains. With review of the stormwater management report, it
appears that the planned infiltration basins have additional capacity to manage the county ROW runoff
in the future. The landlocked basins on site create some challenges but from our review it appears
feasible. The County requests continued coordination to provide stormwater management. The County
has a future project planned with the onset of the new school site, partnering on stormwater
management will help the County and City reduce the number of challenges the future project will pose.
This may require re-working of the proposed infiltration basins to allow the county road to drain to the
new ponds, either via ditches or storm sewer.
County Road 10 and County Road 17 are both listed as priorities for future paved trail development in
Washington County’s Bike and Pedestrian Plan as high and medium priorities, respectively. This
underlines the importance of planning for these future trails as part of the overall site design, including
right-of-way dedication (listed above), grading, and landscaping.
Pedestrians from nearby neighborhoods, especially Cimmaron residents, will want to cross the County
Road 10 and County Road 17 intersection to access the future school and Lake Elmo Park Reserve. The
proposed design and layout should thoughtfully and safely accommodate these users with connections
that are direct and don’t require crossing parking lots and vehicle access roads.
Lake Elmo Park Reserve is owned and operated by Washington County Parks. This land is protected in
perpetuity as part of the Metropolitan Regional Parks system and will not be available for any future
expansion of the proposed school or any other school district use.

Washington County Parks would support a safe and accessible trail connection from the school directly
to the existing trail network within Lake Elmo Park Reserve. Note that the existing trails closest to the
school are ski trails in the winter. Thus, a gate would be needed so the park could seasonally close the
trail to prevent impacts from walkers on groomed ski trails. Additionally, fencing and/or native
vegetative screening at the property border with park will be needed. Please contact County Parks staff
for additional guidance on this or the trail connection route.
Thank you again for the opportunity to provide comments on the traffic study for Lake Elmo Elementary.
We look forward to continuing to work with the City of Lake Elmo to ensure that development in this
area is successful and well-served by the transportation network.
