TO: Planning Commission
FROM: Nathan Fuerst, AICP, Consulting Planner
AGENDA ITEM: Oak Land Middle School Improvements - Conditional Use Permit, Minor
Subdivision, and Variance
REVIEWED BY: Jason Stopa, Community Development Director
Sophia Jensen, City Planner
BACKGROUND:
The City of Lake Elmo received a request from the Stillwater Area Public School District, ISD 834, to
expand the existing Oak Land Middle School building. Enrollment is projected to increase from 1040
students to 1250 students. In a 2023 special election, the Stillwater Area School District successfully
received approval of a bond request to finance this expansion. The improvement proposed to the Oak
Land Middle School building includes 8 new classrooms and a new gymnasium that will also serve as a
storm shelter for the building. Other site improvements include more parking space and a service road
behind the building to meet emergency service access requirements.
The following applications were required for this project:
1. Conditional Use Permit (CUP) – The Stillwater Area School District does not have a
conditional use permit for this site. The Public Facilities zoning district requires a CUP for this
use, a public school, and the requirement is triggered by an expansion of the existing use. The
CUP will cover the entire site.
2. Minor Subdivision – The School District’s use of the Oak Land middle school site spans across
two parcels. The unaddressed western parcel is landlocked, and has a track and other sports
fields. For the entire site to meet impervious surface requirements, the two parcels need to be
combined. Some right-of-way (ROW) is also needed for this site to conform with the County
comprehensive plan for the two abutting county road corridors. ROW can be dedicated through
the minor subdivision process.
3. Variance – A variance to the maximum lot area in the PF District of 20 acres is required. The
lots will be combined through the minor subdivision process, requiring a variance to this
standard.
ISSUE BEFORE THE PLANNING COMMISSION:
The Planning Commission is being asked to review the conditional use permit, minor subdivision, and
variance requests to make a recommendation to the City Council.

Minimum Lot Area. The Oak-Land Middle School site is comprised of two parcels that total 37.19
acres. This is above the City’s maximum lot area of 20 acres. Because the school is expanding its use of
the site and required to combine parcels and dedicate right of way through the minor subdivision
process, the City has required a variance be approved. Staff support a variance to the City’s maximum
lot size due to the fact that the Public School land use is already established on this site and that a minor
3
subdivision will provide necessary public right of way, clean up lot lines and legal descriptions, and
allow the School site to meet applicable requirements for impervious surface.
Tree Preservation. Limited tree removals are proposed on the site primarily to allow required public
sewer connection, and to allow installation of storm sewer south of the building. There are 2994
significant inches indicated by the Applicant to be currently on site. The allowable removal at 30% is
898 inches. As proposed, the School District will only remove 402 inches, not triggering a need for
mitigation. The City’s Landscape Architect has required a revision to the calculation in order to remove
Siberian Elm, Box Elder, and Eastern Cottonwood trees from the table as they are not considered
significant. Revisions are also required to details provided the plans. The Applicant will be required to
revise and resubmit accordingly.
Shoreland Standards. Together, the two parcels comprising the Oak Land Middle School site abut
Rose Lake which is classified as a natural environment lake by the City’s Shoreland Ordinance. The
City’s ordinance permits this use in the shoreland overlay and establishes several performance standards
for existing and future development. First, the site is subject to a 15% impervious surface maximum.
The site will meet that standard with the new expansion bringing total lot coverage to 14.03% within the
shoreland area. The School District’s proposed improvements will also stay outside of the 150’ setback
from Rose Lake and will result in modification of no riparian vegetation.
Landscaping. The City’s Landscape Architect has reviewed the planting plan for conformance with the
City’s ordinance. The Applicant will need to recalculate the total number of trees that are required for
the site. It is anticipated that additional trees will be required, and plantings in parking areas or along the
southern lot line (as discussed in the section below) would satisfy overall tree planting requirements.
Other details will be required to plans revised and resubmitted by the Applicant.
Buffering and Screening. This property is abutting one existing single family residential property to
the north and several larger parcels to the west and south that are undeveloped but guided for residential
development. A majority of tree removals proposed on this parcel are coming from the southern lot line
which abuts a parcel anticipated to have future residential development. Staff suggest that additional tree
plantings be required in the area between the structure and the southern property line in order to replace
the screening that will be lost. A mix of evergreen and deciduous trees of varying species should be
provided to allow year-round screening.
Building Design. Elevations submitted with the site plans indicate two different treatments for the
building. The exterior of all new classroom areas would be constructed with the same materials currently
on the principal structure; however, the two-story gymnasium area would be constructed with precast
concrete panels and surfaced with exposed aggregate. The building materials and façade elevations
proposed are consistent with the City’s design standards manual and are therefore found acceptable.
Parking. City code requires three spaces per classroom. There are 58 rooms that are classrooms or an
equivalent learning space. Therefore, a minimum of 174 parking spaces are required. There are a total of
172 parking spaces supplied in areas not used by buses, and a total of 295 on site if the bus turnaround
area is included. The back row of the bus turnaround area appears to not impede bus operations, which
could add an additional 30 parking stalls if fully utilized. This site meets the parking minimum
established by code.
4
Traffic and Access. 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 staff have indicated the following comment regarding concern for exacerbating the
existing conditions:
Despite recent investments in a traffic signal and additional length on the exit lanes, the school
currently has issues with vehicles queuing along CSAH 15 and delays in exiting the site during
peak times. Queuing on highway shoulders or turn lanes causes obstructed sight lines for
drivers, the denial of left-in access during peak times, and incentivizes drivers to make U-turns
to join the queue. Washington County is concerned that expanding the school enrollment will
exacerbate the queuing, delay, and safety issues if additional improvements are not made to
provide more internal vehicle stacking space
Washington County will ultimately require an access permit for the use to be intensified in a manner that
would impact or adversely affect the safety or operations of the county road as determined by the
County Engineer. Washington County engineering staff’s have provided the following recommendations
which are paraphrased for brevity:
1. Provide two internal circulation lanes to allow leapfrogging.
2. Increase inbound capacity modifying the inbound lanes to wrap around parallel to the exit lanes.
3. Construct pedestrian infrastructure, particularly connecting to the existing neighborhoods located
along Palmer Drive and a connection to the Cimarron development.
4. Create bike and pedestrian connections to and through the south growth area as it develops to
reduce vehicle dependency.
The City Engineer has provided the following comments in their memo related to Transportation
Improvements and Access:
1. Access Management. The CUP/Minor Subdivision approval should be contingent upon the
District agreeing to allow the southern secondary school access to Manning Avenue to be
relocated further south when the future neighborhood collector roadway is needed to serve this
future development area.
2. Plan Sheet AP 5 should be revised to remove the Future Development Access proof of concept.
The exhibit shows that the future development access does not work as intended to serve as a
neighborhood collector roadway for the future development area. The southern school access to
Manning Avenue will be required to be relocated further south of the existing signalized
intersection and the school will be required to reconnect to the new access location at its sole
cost.
3. The City supports the County’s request for the District to make internal site and operational
improvements as necessary to mitigate the peak traffic queuing onto Manning Avenue (CSAH
15) by parent drop-offs and pickups.
Suggested conditions of approval have been added to address the concerns of both Washington County
and City Engineering staff.
CONDITIONAL USE PERMIT FINDINGS: City Code Section 105.12.290(a) provides findings
required for Conditional Use Permit approval. Staff recommends the following findings:
5
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 heath, safety, comfort,
convenience or general welfare of the neighborhood or City.
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
expansion is to a middle school that has been in operation for over two decades. The land
use 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.
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). Part of the property falls within the shoreland
area of Rose Lake. The use is consistent with requirements found in the City’s Shoreland
Regulations.
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 addition and new building
are designed to be compatible with the existing structure character. The character of the
general vicinity should not be changed.
7. The proposed use will not be hazardous or create a nuisance as defined under this Chapter to
existing or future neighboring structures. The Applicant is not requesting a variance to
performance standards other than to have a larger parcel than that required by City
Ordinance. 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 should not create additional requirements at public cost, and will provide an
expanded capacity to serve area residents with educational services. Future relocation of
access may be required by the City to mitigate concerns with impacts to Manning Avenue
from this use.
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.
6
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 not result in the destruction, loss
or damage of the natural environment, and will meet applicable performance standards.
RECOMMENDED MINOR SUBDIVISION FINDINGS.
The process for review of subdivisions is established in City Code Section 103.00.070. While specific
findings are not established in that ordinance, staff recommends the following findings:
• That the Oak-Land Middle School Addition minor subdivision is consistent with the Lake Elmo
Comprehensive Plan and the Future Land Use Map for this area.
• That the Oak-Land Middle School Addition minor subdivisions is consistent with the future
development plans of the area and with the standards of the City’s Public Facilities zoning
district.
• That the Oak-Land Middle School Addition minor subdivision meets the requirements of the
City’s minor subdivision regulations and specifically the requirements concerning exceptions to
platting.
RECOMMENDED 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.
The use proposed by the Applicant is already established on the entire site which will be 37.04
acres as combined after required right of way dedication is removed. Combining the two parcels
through a minor subdivision will provide necessary public right of way, clean up lot lines and
legal descriptions, and allow the School site to meet applicable requirements for impervious
surface and setbacks.
2) Unique Circumstances. The plight of the landowner is due to circumstances unique to the property
not created by the landowner.
The Applicant is not proposing to expand the school’s building or site improvements beyond the
existing boundaries of the Oak Land Middle School property.
3) Character of Locality. The proposed variance will not alter the essential character of the locality in
which the property in question is located.
7
The variance should not impact essential character; the use of the facilities is to remain the same.
The request meets the overall design intent of this area.
The variance request should not impact essential character.
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.
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.

Comm. No: 232260
Subject: Independent School District #834
Oak-Land Middle School Addition and Renovation
Submittal to City of Lake Elmo on behalf of Stillwater Area Public Schools, for the
proposed additions to Oak-Land Middle School, located at 820 Manning Avenue,
Lake Elmo, Minnesota 55042 (Property ID #3602921110002, #3602921110003)
Conditional Use Permit, Minor Subdivision, and Variance Submittal Narrative:
On behalf of Stillwater Area Public Schools, we are submitting for City staff review a Conditional
Use Permit, Minor Subdivision, and Variance application for the proposed additions to Oak-Land
Middle School. The additions are in response to a projected increase in student enrollment from
1,040 students to 1,250 students, and will include two new science classrooms, six general education
classrooms, and a two-station gymnasium that will also serve as a storm shelter for the entire
facility. Associated staffing needs are anticipated to increase from 102 existing, to 125. The existing
building is 134,880 square feet, the additions will be approximately 29,000 square feet cumulatively,
for a total of 163,880 square feet. The classroom additions will be single story, with exterior
materials and design aesthetics to match the existing building. The gymnasium addition will
include a small single-story portion between the gymnasium and the remaining building, with the
gymnasium being a two-story structure comprised of precast concrete. The anticipated school day
schedule is currently planned to be from 8:35am to 3:05pm.
Site improvements include increasing the parking stall count by 35 stalls for a total of 174, to
accommodate staffing increases and abide by City ordinance requirements, and the introduction of
a hard-surface emergency vehicle access route extending from the north parking lot to the west of
the facility. All stormwater control is designed to address needs onsite. Additionally, the District is
considering connections to public water and sewer utilities and working with the City and County
to determine the necessary scope requirements to transition the school to public utilities, from
existing well-water and a below-grade septic system. The City is currently facilitating a feasibility
study to determine overall scope and cost implications. It is anticipated that the study will indicate
a new gravity-fed sanitary line will replace the septic system, extend north to connect to a lift
station that currently serves Royal Oaks Golf Course to the north of 10th Street North.
August 2, 2024
MEMORANDUM

A forced main routed from that lift station to the west will connect to another forced main below
Lake Elmo Avenue North, which connects to the proposed new Lake Elmo Elementary School. Also
included in this submittal is the completed traffic study, which reviewed existing vehicular and
pedestrian traffic on and around the site; and a conceptual diagram showing a potential access road
to a possible future residential development to the south of Oak-Land Middle School.
Anticipated mobilization, ground-breaking and building shell construction of the additions is
planned to occur in Spring 2025. Construction of the two classrooms additions is expected to be
completed by August 2025, with the gymnasium addition concluding in the winter of 2025-2026.

OUT. TEMPORARY SEDIMENT BASINS SHALL BE INSTALLED AS DIRECTED BY THE CITY ENGINEER.
7.ROCK CONSTRUCTION ENTRANCE. A ROCK ENTRANCE SHALL BE CONSTRUCTED AND MAINTAINED AS SHOWN ON THE
PLAN TO REDUCE TRACKING OF SILT AND DIRT ONTO THE PUBLIC STREETS. A GEOTEXTILE FABRIC SHALL BE PLACED
UNDERNEATH THE ROCK. THE ROCK SHALL BE PERIODICALLY REPLENISHED TO MAINTAIN THE INTENDED
PERFORMANCE. MUD AND DEBRIS SHALL BE REMOVED OR SCRAPED FROM TIRES AND VEHICLE UNDERCARRIAGE PRIOR
TO LEAVING THE SITE.
8.STREET SWEEPING. ALL STREETS USED FOR ACCESS TO THE SITE AND HAUL ROUTES USED FOR CONSTRUCTION
EQUIPMENT AND MATERIAL SUPPLIES SHALL BE CLEANED AT THE END OF EACH WORKING DAY. THE CITY OR ENGINEER
MAY ORDER ADDITIONAL SWEEPING OF THE STREETS AS DEEMED REQUIRED AT DEVELOPER/CONTRACTOR EXPENSE.
9.DEWATERING. EACH EXCAVATION SHALL BE KEPT DRY DURING THE COURSE OF ALL WORK HEREIN, INCLUDING
SUBGRADE CORRECTION, PIPE INSTALLATION, STRUCTURE CONSTRUCTION AND BACKFILLING, TO THE EXTENT THAT NO
DAMAGE FROM HYDROSTATIC PRESSURE, FLOATATION OR OTHER DAMAGE RESULTS. ALL EXCAVATIONS SHALL BE
DEWATERED TO A DEPTH OF AT LEAST 3 INCHES BELOW THE BOTTOM OF THE CONCRETE SLAB OR PIPE TO BE
INSTALLED THEREIN. THE CONTRACTOR MAY USE ANY METHOD OR COMBINATION OF METHODS FOR DEWATERING HE
CHOOSES; HOWEVER, ALL DEWATERING METHODS AND EQUIPMENT WHICH IN THE OPINION OF THE ENGINEER, ARE
INEFFECTIVE SHALL BE ABANDONED, IMPROVED, REPLACED OR THERWISE ALTERED TO OBTAIN EFFECTIVE
DEWATERING. THE CONTRACTOR SHALL PROVIDE ALL POWER, PUMPS, MATERIALS AND APPARATUS NECESSARY, AND
SHALL BE RESPONSIBLE FOR DISPOSING OF THE WATER PUMPED FROM THE EXCAVATION IN A MANNER WHICH WILL NOT
INTERFERE WITH OTHER WORK WITHIN THE AREA AND NOT TO DAMAGE PUBLIC OR PRIVATE PROPERTY. THE
CONTRACTOR WILL BE HELD RESPONSIBLE FOR THE CONDITION OF ANY PIPE, CONDUIT, DITCH, CHANNEL OR NATURAL
WATERCOURSE UTILIZED FOR DRAINAGE PURPOSES, AND ALL EROSION, SEDIMENT OR OTHER ADVERSE RESULTS OF
THEIR USE SHALL BE REPAIRED.
10.POSITIVE DRAINAGE AND PROTECTION. THE CONTRACTOR SHALL MAINTAIN POSITIVE DRAINAGE THROUGHOUT THE
SITE AT ALL TIMES. LOW POINTS WITHIN AND ALONG ROADWAYS ARE EXPRESSLY PROHIBITED. THE CONTRACTOR
SHALL BE RESPONSIBLE FOR TEMPORARY DITCHES, PIPING OR OTHER MEANS TO FACILITATE PROPER DRAINAGE
DURING CONSTRUCTION. TO PROTECT PREVIOUSLY GRADED AREAS FROM EROSION, WOOD FIBER BLANKET SHALL BE
PLACED IMMEDIATELY ON STEEP SLOPES (1:3 OR GREATER) AND EMBANKMENTS, PERMANENT AND TEMPORARY PONDS,
AND OUTLETS AND OVERFLOWS TO PROTECT THE COMPLETED GRADE AND MINIMIZE SILT IN THE RUNOFF.
11.DRAINAGE DITCHES. THE NORMAL WETTED PERIMETER OF ANY TEMPORARY OR PERMANENT DRAINAGE DITCH OR
SWALE THAT DRAINS WATER FROM ANY PORTION OF THE CONSTRUCTION SITE, OR DIVERTS WATER AROUND THE SITE,
MUST BE STABILIZED WITHIN 200 LINEAL FEET FROM THE PROPERTY EDGE, OR FROM THE POINT OF DISCHARGE INTO
ANY SURFACE WATER. STABILIZATION OF THE LAST 200 LINEAL FEET MUST BE COMPLETED WITHIN 24 HOURS AFTER
CONNECTING TO A SURFACE WATER. STABILIZATION OF THE REMAINING PORTIONS OF ANY TEMPORARY OR
PERMANENT DITCHES OR SWALES MUST BE COMPLETE WITHIN 14 DAYS AFTER CONNECTING TO A SURFACE WATER AND
CONSTRUCTION IN THAT PORTION OF THE DITCH HAS TEMPORARILY OR PERMANENTLY CEASED. TEMPORARY OR
PERMANENT DITCHES OR SWALES THAT ARE BEING USED AS A SEDIMENT CONTAINMENT SYSTEM (WITH PROPERLY
DESIGNED ROCK DITCH CHECKS, BIO ROLLS, SILT DIKES, ETC.) DO NOT NEED TO BE STABILIZED. THESE AREAS MUST BE
STABILIZED WITHIN 24 HOURS AFTER NO LONGER BEING USED AS A SEDIMENT CONTAINMENT SYSTEM.
12.TURF ESTABLISHMENT. ALL EXPOSED SOIL AREAS MUST BE STABILIZED AS SOON AS POSSIBLE TO LIMIT SOIL EROSION
BUT IN NO CASE LATER THAN 14 DAYS AFTER THE CONSTRUCTION ACTIVITY IN THAT PORTION OF THE SITE HAS
TEMPORARILY OR PERMANENTLY CEASED.
13.MAINTENANCE AND INSPECTION. EROSION CONTROL MEASURES SHALL BE MAINTAINED THROUGHOUT THE
CONSTRUCTION AND UNTIL SATISFACTORY ESTABLISHMENT OF PERMANENT GROUND COVER IS OBTAINED. ALL
EROSION AND SEDIMENTATION CONTROL MEASURES, AND STORMWATER OUTFALLS MUST BE INSPECTED WEEKLY, AND
WITHIN 24 HOURS OF THE SITE RECEIVING 0.5 INCHES OF RAIN. REPAIRS MUST BE MADE ON THE SAME DAY OR
FOLLOWING DAY OF THE INSPECTION. UNSATISFACTORY CONDITIONS NOT REPAIRED OR CLEANED UP WITHIN
48-HOURS OF NOTIFICATION SHALL RESULT IN A STOP WORK ORDER, AND/OR SAID WORK SHALL BE COMPLETED AT
CONTRACTOR'S EXPENSE.
14.REMOVAL. THE CONTRACTOR SHALL REMOVE AND DISPOSE OF ALL TEMPORARY EROSION CONTROL MEASURES,
STRUCTURES AND DEVICES ONLY AFTER RECEIVING ENGINEER APPROVAL. ALL DEBRIS, STAKES, AND SILTS ALONG SILT
FENCES SHALL BE REMOVED AND DISPOSED OFF SITE. THE CONTRACTOR SHALL HAND RAKE SILTED AREAS ALONG THE
FENCE LOCATIONS TO PROVIDE A SMOOTH FINAL GRADE AND SHALL RESTORE THE GROUND SURFACE WITH SEED OR
SOD, AS REQUIRED, TO MATCH THE FINISHED GRADE TO THE ADJACENT AREA.
15.FINAL STORM SEWER SYSTEM. AT THE COMPLETION OF THE WORK AND BEFORE THE FINAL WALK THROUGH, THE
CONTRACTOR SHALL REMOVE STORM SEWER INLET PROTECTION MEASURES AND THOROUGHLY FLUSH THE STORM
SEWER SYSTEM. SEDIMENT AND DEBRIS SHALL BE COMPLETELY REMOVED AND CLEANED AT THE INLETS, OUTLETS, AND
DOWNSTREAM OF EACH OUTLET. RIPRAP AND GEOTEXTILE FABRIC MAY REQUIRE REPLACEMENT AS DIRECTED BY THE
ENGINEER TO OBTAIN A LIKE NEW INSTALLATION ACCEPTABLE TO THE CITY
16.DITCH CHECK (BIOROLL BLANKET SYSTEM). BIOROLL AND BLANKET SYSTEMS SHALL BE INSTALLED AS DITCH CHECKS
ONLY IN SPECIFIED LOCATIONS AS APPROVED BY THE CITY ENGINEER. BIOROLLS ARE NOT TO BE UTILIZED IN AREAS
WHERE VEHICLE AND CONSTRUCTION TRAFFIC OCCUR.
17.FLOTATION SILT CURTAIN. FLOTATION SILT CURTAIN SHALL BE UTILIZED WHEN CONSTRUCTION ACTIVITIES OCCUR
DIRECTLY ADJACENT TO LAKES, STREAMS OR WETLANDS IN ORDER TO CONTAIN SEDIMENTS NEAR THE BANKS OF
WORKING AREAS. THE INSTALLATION OF FLOTATION SILT CURTAINS WILL BE REQUIRED AS DIRECTED BY THE CITY
ENGINEER.

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.

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.

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.

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.

The middle school has two separate parking lot/vehicular access locations, each serving a different
purpose for the school.
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.

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

E > 55 - 80 > 35 - 50
F > 80 > 50

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.

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 (ICRS) 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.

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.

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).

Total Site Trips 1,250 443 376 172 228 101 146 2,857
Results of the trip generation estimate indicate that Oak-Land Middle School is expected to generate
an additional 196 school arrival peak hour, 95 school departure peak hour, 59 p.m. peak hour, and
685 daily trips with the new enrollment. 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.

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.

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.

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.

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.

In addition to assessing the 10th Street/Lake Elmo Avenue intersection, daily volumes were also
reviewed along the study roadways. A summary of the current background traffic and the traffic
volume changes associated with the school developments is shown in Figure 11. Note the background
traffic volumes are based on the 24-hour volumes collected as part of the study and adjusted using the
general background growth rate. The ADT comparison indicates that most study roadways are only
anticipated to increase by approximately one (1) to 10 percent as a result of the school developments.

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.

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.

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.

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.

Chad Isakson, PE, Assistant City Engineer
From: Jack Griffin, PE, City Engineer
Engineering has reviewed the ISD 834 Oak‐Land Middle School CUP and Minor Subdivision site plans received on
August 16, 2024. The review consisted of the following documentation:
Application Narrative dated August 2, 2024.
Oak‐Land Middle School Addition Civil Site Plans, Sheets C000 and C703, dated August 2, 2024.
PRELIMINARY AND FINAL PLAT
1. County Roadway Right‐of‐way Dedication. As part of the Minor Subdivision, right‐of‐way dedication must
be provided along Manning Avenue (CSAH 15) and 10th Street (CSAH 10) in accordance with the
Washington County Transportation Plan and as approved by both the City and the County. The Preliminary
and Final Plat documents submitted as part of the application lack sufficient detail to allow for City review
and approval. Revised Preliminary and Final Plats are needed to detail the right‐of‐way dedication
requirements and to depict how those requirements are being met.
2. The extension of public watermain is proposed as part of the School Addition CUP/Minor Subdivision.
Easements must be provided, minimum 30‐foot‐wide centered over all public watermain/hydrant(s) when
not located within the public right‐of‐way. Easements must be free from all encroachments, including
retaining walls, trees, fences, small/dry utilities, or storm water management BMPs. Easements have been
shown on the Preliminary and Final Plats, however, extensive revisions will be required once the final utility
layout is approved by the City.
3. The Preliminary Plat scale must be corrected to facility additional review.
TRANSPORTATION IMPROVEMENTS AND ACCESS
1. Access Management. The CUP/Minor Subdivision approval should be contingent upon the District agreeing
to allow the southern secondary school access to Manning Avenue to be relocated further south when the
future neighborhood collector roadway is needed to serve this future development area.
2. Plan Sheet AP 5 should be revised to remove the Future Development Access proof of concept. The exhibit
shows that the future development access does not work as intended to serve as a neighborhood collector
roadway for the future development area. The southern school access to Manning Avenue will be required
to be relocated further south of the existing signalized intersection and the school will be required to
reconnect to the new access location at is sole cost.
3. The City supports the County’s request for the District to make internal site and operational improvements
as necessary to mitigate the peak traffic cueing onto Manning Avenue (CSAH 15) by parent drop‐offs and
pickups.
PAGE 2 of 3
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. 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.
3. 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 HWL, 10‐foot maintenance
bench and all maintenance access roads. Maintenance access roads meeting City standards must be
provided for all storm water facilities and structures.
4. 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.
5. Overland emergency overflows (EOF) or outlets will be required as part of the site plan and the EOFs and
EOF flow routes must be protected by easement.
6. 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 listed on the site and
grading plans.
7. All localized low points must be protected within a drainage easement.
MUNICIPAL WATER SUPPLY AND PUBLIC SANITARY SEWER
1. The proposed site is located within the City designated Municipal Urban Service Area (MUSA) for sanitary
sewer service. Due to the plans to expand the school use, the extension of public watermain and sanitary
sewer should be implemented as part of the improvements. A feasibility report has been authorized to
identify the scope of improvements and costs necessary to connect the Oak‐Land Middle School to City
water and sewer.
2. Connection to City water and sewer would be made available by extending a 12‐inch diameter trunk
watermain and 8‐inch diameter gravity sanitary sewer pipe from the intersection of Palmer Drive and 10th
Street, and extend these utilities easterly along 10th Street to the northern District property line. For the
sanitary sewer, additional lift station and forcemain improvements will need to be completed to
accommodate the added sewer flow. The District would then be responsible for paying their prorated costs
for these City installed improvements and then connecting to the City water and sewer stubs and to route
additional infrastructure internal to the site.
3. The District’s internal site improvements must include water and sewer connection to the Oak‐Land Middle
school, 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, and the extension of a 12‐inch diameter trunk
watermain from the District’s northern property line and stubbed to the District’s southern property line
for future development to the south.
4. The internal site sanitary sewer would be a privately District owned sewer service. The internal watermain
serving all hydrants and stubbing to the southerly property would remain City owned. Minimum 30‐foot
easements centered over the pipe/hydrant will be required when not located within the public right‐of‐
way. Easements must be free from all encroachments, including retaining walls, trees, fences, small/dry
utilities, or storm water management BMPs. Easements must be dedicated to the City as part of the project.
5. Watermain oversizing costs apply to watermain pipe sizes over and above the minimum 8‐inch diameter
design standard. Reimbursement of oversize costs are addressed as part of the site improvement
agreement.
PAGE 3 of 3
PRELIMNARY PLANS/CONSTRUCTION PLANS
1. Existing conditions plan sheets must be revised to include all required existing condition information as
shown on the Topographic Survey plan sheet, including all easements and property lines being labeled and
dimensioned.
2. Utility Plans must be revised to clearly depict public vs. private utility ownership. Watermain layout must
be revised to provide additional and relocated hydrants as directed by the Lake Elmo Public Works Director
and Fire Department. The watermain running north‐south across the property from 10th Street to the
southern school district property line shall be increased to a 12‐inch DIP watermain.
3. The grading plans must be revised to include all design information required by the City design standards,
including all basin and low area 100‐year HWL elevations, all NWL elevations, all building low floor and low
opening elevations, all low area EOF’s, a clear depiction of the EOF flow route throughout the site, all storm
water basin maintenance access roads, and all required stormwater easements.
4. Detail plan sheets must incorporate all City standard details for erosion control and watermain utilities and
all conflicting details must be removed.

REVIEW HISTORY
1. August 27th, 2024: CUP, Minor Subdivision, and Variance Submittal Landscape Plan Review
LOCATION: 820 Manning Avenue, Lake Elmo MN 55042
CURRENT LAND USE CATEGORY: Public Facilities (PF)
ADJACENT AND SURROUNDING LAND USE: Golf Course Community to the north, Rural
Residential to the north and west, Medium Density Residential to the west and south, Rural
Transitional to the south. West Lakeland Township is to the east.
SPECIAL LANDSCAPE PROVISIONS: Shoreland Overlay District for Rose Lake along the
northwest 2/3 of the site
TREE PRESERVATION PLAN: 105. 12. 470
• A tree preservation plan was submitted, but requires the following adjustments prior to approval:
o Sheet C100 shows tree protection fencing in the legend, but not on the plans. Please include
this fencing on the plans and add the City Standard Detail for tree protection to this sheet or
refer to it if placed elsewhere within the set.
o Rename sheet C500 with the title “Tree Preservation Plan” and revise the sheet callouts in
each quadrant with the appropriate numbers (C501, C502, or L100, L101 etc.)
o Revise the tree inventory on sheet C505 to remove the following species from the table, as
they are not considered significant: Siberian elm, box elder, and Eastern cottonwood.
o Revise the total significant inches number on sheets C500 and C505. Edit calculation of
percent inches removed accordingly. No tree mitigation will be required if the total inches
proposed to be removed still falls under 30% of the total, but this needs to be confirmed.
LANDSCAPE PLAN: 105.12.480
• A landscape plan was submitted, but requires the following adjustments prior to approval:
o Please provide calculations that confirm the number of trees required per the landscaping
code: 5 trees per disturbed acre + interior parking lot landscaping trees (may be counted
August 27, 2024
Oak-Land Middle School
Memorandum 2
toward the disturbed acre requirement). Also include any trees required by the revised tree
preservation plan.
Interior parking lot landscaping is required for the proposed parking expansion: 1 tree
for every 10 parking lot spaces or fraction thereof. With more than 40 spaces, 5 trees
will be required. Please add an additional tree within a planting island or along the
border of the parking lot.
o Ground cover materials should be defined with their own separate hatches (seeded, sodded,
and mulched areas) showing the extent of disturbed area restoration.
o Provisions for irrigation are required. Please include an irrigation plan or notes detailing how
trees and planting materials will be watered through the warranty period.
o Include the City Standard Tree Planting Detail.
o Revise landscaping note #7 on sheet C600 to read “6’ diameter and 4” deep.”
o A Topsoil Preservation Plan is required per 105.12.480 (a) (9). I could not locate an area
showing where site topsoil would be stored on the plans. Please ensure this is called out
somewhere on the drawings (Sheet C300 would be a good place).
GENERAL NOTES:
• I have some concern about how well American Larch will do on the dry slope along the utility corridor
that extends up to 10th street. They generally want more soil moisture. I would recommend selecting
another species.
• Please select a Dutch Elm-resistant cultivar of Elm rather than specifying Ulmus Americana.
RECOMMENDATION:
The landscape and tree preservation plans must be revised and resubmitted to address the items in this
memo.

Oak-Land Middle School – Conditional Use Permit, Minor Subdivision, and Variance Application
Dear Sophia,
Thank you for the opportunity to review and comment on the application for the Oak-Land Middle School
expansion, located along County State Aid Highway (CSAH) 15 (Manning Avenue) and adjacent to the intersection
of CSAH 15 & CSAH 10 (10th St). The county thanks the City of Lake Elmo and the Stillwater School District for
meeting with the county to discuss the expansion of the school 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 expansion, but we have concerns with some of the design details.
The plan proposes two new science classrooms, six general education classrooms, and a two-station gymnasium.
According to the narrative, this would potentially increase the staff by 23 and add 210 students.
The school is heavily dependent on vehicular transportation as the area largely lacks pedestrian connections, and
the school is located within walking distance of a few residences. Despite recent investments in a traffic signal and
additional length on the exit lanes, the school currently has issues with vehicles queuing along CSAH 15 and delays
in exiting the site during peak times. Queuing on highway shoulders or turn lanes causes obstructed sight lines for
drivers, the denial of left-in access during peak times, and incentivizes drivers to make U-turns to join the queue.
Washington County is concerned that expanding the school enrollment will exacerbate the queuing, delay, and
safety issues if additional improvements are not made to provide more internal vehicle stacking space.
The traffic plan submitted with the application states, “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.” The county would not permit an access for which the plans indicated that queues extended
into traffic on any roadway, much less a 55-mph county highway. As such, the county offers the following
recommendations regarding the queueing plan:
1. Providing two internal circulation lanes to allow leap-frogging may be beneficial, allowing parents to pull
forward to reach any open curb gaps rather than proceeding single-file.
2. Another option would be to increase inbound capacity modifying the inbound lanes to wrap around
parallel to the exit lanes, as shown in the image below. The outbound lane could possibly be able to be
reduced to a single lane in this area, but two exiting lanes will still be needed for a sufficient distance on
approach to the traffic signal.
3. The construction of pedestrian infrastructure, particularly connecting to the existing neighborhoods
located along Palmer Drive and a connection to the Cimarron development will help reduce the need for
vehicular trips to the school and is consistent with County long-term plans.
4. As the area to the south develops, the school, city, and county should work collaboratively to reduce
vehicular dependency by constructing and integrating non-motorized connections to the surrounding
community. The pedestrian routes should connect with nearby neighborhoods, both existing and planned,
and provide safe and reasonable direct access into the school site itself.
Although not part of the current proposal, the district’s drawing showing future additional expansion phases
would require relocation of the current outbound traffic lanes, and likely necessitate future expansion of the
school site southward into what is currently private property. Such expansion, along with a new east-west street
serving new development, could provide valuable opportunities to improve internal stacking space and safer
access to the county highway system. Any such improvements will necessitate careful coordination between the
property owner, city, school, and county regarding relocation of the existing signalized intersection and future
additional development of the property to the south. It would be advantageous to have preliminary discussions
this year regarding those future phases to ensure that current proposals do not preclude such future
improvements. Any reconstruction or relocation of the intersection would be subject to Washington County’s Cost

Utilities
In their 8/02/2024 Conditional Use Permit Variance Submittal to the City, Wold Architects and Engineers states
that the District is considering connections to public water and sewer utilities. As stated the property is currently
served by onsite well and septic system and these systems. Prior to approval of the proposed expansion, the
wastewater treatment needs must be addressed. If onsite subsurface sewage treatment is necessary, the current
system must either be inspected and found to be compliant and adequate or properly abandoned and replaced
with an approved new installation. Because onsite sewage treatment systems require natural soil for placement
and have setbacks to structures, property lines, and other infrastructure both on and off the site, it is important
that these utilities and needs be addressed early in the planning process to avoid having to reconfigure site plans
and improvements later in the process.
Permits, Requirements, and Submittals Required by the County
• The necessity of an access permit will depend on the final plans for the school design/addition. The district
and city should continue to work with the county on plan development. Washington County Ordinance
188 indicates the following: “Permit Required. Except as otherwise provided in this Code, no person may
access, landscape, place a service utility, excavate/grade, or obstruct any County Road right of way
without first registering and having obtained the appropriate right of way permit from the County to do
so. Additionally, no person may substantially change the intensity of use of an existing access, in such a
way that the County Engineer determines that such change in use will adversely affect the safety or
operations of the County road, without first registering and having obtained the appropriate access
permit from the County to do so. Multiple permits may be required, as determined by the Engineer, for a
single activity”.
• A Right-of-Way Permit will be required for any work within the county highway right-of-way as it relates to
the expansion project. As the project progresses, a plan-set will be required with the application and
include any grading, culvert installation, water and sewer services, parallel trail development, signage,
landscaping and any other improvements within the county right-of-way.
• All utility connections to county highway right-of-way for the development will also require separate
Washington County Right-of-Way permits.
Washington County looks forward to working with the City of Lake Elmo and the Stillwater School District to
ensure that development in this area is successful and well-served by the transportation network. We look
forward to meeting and continuing the discussion regarding the expansion of the school.
Sincerely,
Daniel Elder
