HENNEPIN COUNTY, MINNESOTA
RESOLUTION NO. 2021-33
RESOLUTION DENYING CITIZEN PETITION FOR PREPARATION OF AN
ENVIRONMENTAL ASSESSMENT WORKSHEET FOR THE PROPOSED
NOBLE HILL PROJECT
WHEREAS, on April 23, 2021, the City of Eden Prairie received from the Environmental Quality
Board ("EQB") a petition requesting that the City Council require an environmental assessment
worksheet ("EA W") for the proposed project known as Noble Hill, to be located at 9955 and 9875
Spring Road, Eden Prairie, MN 55347 (the "Project"); and
WHEREAS, the petition was signed by 221 individuals, more than half of which are Eden Prairie
residents; and
WHEREAS, the EQB has designated the City as the responsible governmental unit ("RGU") for
the Project; and
WHEREAS, upon receipt of a petition from the EQB, the City must review the evidence presented
by the petitioners, evidence provided by the Project proposer, and other evidence otherwise known
to the City and determine whether, because of the nature or location of the Project, the Project may
have the potential for significant environmental effects; and
WHEREAS, the EQB Rule requires the City to take into account the following factors in
considering the evidence:
A. The type, extent, and reversibility of environmental effects;
B. The cumulative potential effects, including the following factors:
whether the cumulative potential effect is significant; whether the
contribution from the project is significant when viewed in
connection with other contributions to the cumulative potential
effect; the degree to which the project complies with approved
mitigation measures specifically designed to address the cumulative
potential effect; and the efforts of the proposer to minimize the
contributions from the project;
C. The extent to which the environmental effects are subject to
mitigation by ongoing public regulatory authority. The RGU may
rely on mitigation measures that are specific and that can be
reasonably expected to effectively mitigate the identified
environmental impacts of the project;
D. The extent to which environmental effects can be anticipated and
controlled as a result of other available environmental studies
undertaken by public agencies or the project proposer, including
other environmental impact statements.
WHEREAS, the City Council considered the petition for an EA W at its meeting on May 4, 2021.
The petitioners and the Project proposer were provided the opportunity to present information and
comment. The City Council considered all of the evidence and information presented as well as
the staff report, which are incorporated by reference into this resolution.
NOW THEREFORE, BE IT HEREBY RESOLVED BY THE CITY COUNCIL OF THE
CITY OF EDEN PRAIRIE, that the following Findings of Fact and Decision are hereby adopted:
FINDINGS OF FACT
Nature and Location of Project
1. The Project involves the construction of 50 single-family homes on 27.51 acres of land.
The proposed Project has a density of 1.8 dwelling units per acre.
2. The current land use on the site includes agricultural use for a tree farm with a home, barn,
shed, and dirt field paths. The property is located within the City's Metropolitan Urban
Service Area and is guided for Low Density Residential development in the City's
Comprehensive Plan. The Low Density Residential land use category allows a density of
5 units per acre.
3. The Project site has a significant amount of topographic relief. There is a nearly 150-foot
grade change from east to west. Riley Creek runs through a portion of the west side of the
Property. There are floodplains and wetlands along the creek corridor. There is also a bluff
on the southwest comer of the site. There are significant wooded areas along the creek and
on the bluff. In addition, the northeast comer of the property is wooded and there is a line
of mature trees along the east property line.
4. Adjacent land uses to the Project site include conservation land to the south, a residential
development to the east, one residential building to the west, and conservation land to the
north.
5. City-owned property to the west of the Project site contains access to a natural spring
known as the Fredrick-Miller Spring. The spring is designated as a local Heritage
Preservation Site that carries with it local protections through City Code.
Biodiversity of Project Site
6. The petition alleges that the Project site is ecologically significant and that the Project will
negatively impact the biodiversity of the site, including negative impacts to migratory
birds, the Rusty Patch Bumblebee, the Kitten-Tail plant, the Petala Evening Primrose,
significant and heritage trees, and wildlife habitat.
2
Type, extent, and reversibility of environmental effects
7. The vast majority of the area identified on the Hennepin County Natural Resources
Inventory Map as "DNR Sites of Biodiversity Significance" will remain undisturbed by
the Project. This area is contained within Outlot D of the Project site and is proposed to be
deeded to the City for preservation. These lands, when combined with the current Prairie
Bluff Conservation Area, provide a natural buffer between developed areas and existing
water bodies. Preserving this area of the Project site minimizes any potential effects to
biodiversity.
8. The Project area is included in the Minnesota River Valley Important Bird Area
("MRVIBA"). The MRVIBA is a corridor extending a certain distance from the Minnesota
River that migratory birds use as a flyway. The MRVIBA includes a wide variety of both
developed and undeveloped areas.
9. Inclusion in the MRVIBA does not mean that the Project site has been surveyed and
identified as an Important Bird Area. Petitioners have presented no evidence that any birds
will be particularly impacted by the Project.
10. Species included on Minnesota's List of Endangered, Threatened and Special Concern
Species have been found in the area surrounding the Project site. The City will require a
survey to be completed prior to the issuance of a Land Alteration Permit to identify any
endangered, rare, and threatened species on the site, including but not limited to Kitten-
Tails, Petala Evening Primrose, and the Rusty Patch Bumble Bee, and provide findings to
the City. Any impacts to such species that are found within the grading limits of the Project
must be mitigated.
11. The Project proposer has provided a Rare Plant Survey report prepared by Stantec dated
April 27, 2021. The survey found no kitten-tails or other rare plants at the Project site
within the proposed limits for tree clearing or grading or within the proposed Outlot D.
12. 445 significant trees will be removed from the Project site. Most of these trees will be
removed from the northern parts of the property in an effort to save the trees on the more
environmentally sensitive property on the southwest of the Project site. The developer will
undertake tree replacement efforts as required by City Code, both in the form of actual
replacement and payment-in-lieu of replacement that will provide funds for the City to
plant trees throughout the City.
Cumulative potential effects
13. There are no significant cumulative potential effects related to biodiversity.
14. Past developments surrounding the Project site have been subject to the same review
process as this Project, which takes into account biodiversity concerns.
15. There are no other known proposed projects in the Project area to be considered for
potential cumulative effects related to biodiversity.
3
Mitigation bv ongoing regulatory authority
16. Because the majority of the portion of the Project site identified as having biodiversity
significance will be deeded to the City for conservation, the City will be able to monitor
and mitigate any biodiversity concerns.
Other studies
17. Studies that describe how environmental effects the biodiversity of the Project site can be
anticipated and controlled include the following, which have been considered by the
Council and are incorporated herein by reference: Rare Plant Survey report prepared by
Stantec dated April 27, 2021.
Riley Creek Impairment
18. The petitioners assert that Riley Creek (the "Creek") will become further or irreversibly
impaired by the Project. They cite increased impervious area in the Creek watershed,
stresses from existing developments, decreased forest cover, and landslide potential as
negative impacts to the Creek.
Tvpe, extent. and reversibility of environmental effects
19. The Minnesota Pollution Control Agency's ("MPCA") Lower Minnesota River Watershed
Total Maximum Daily Load Study (February 2020) ("TMDL Study"), states that the Creek
is impaired for Total Suspended Solids ("TSS") and Escherichia Coli ("E. coli") bacteria.
Further impairments for aquatic macroinvertebrate bioassessments and macroinvertebrate
bioassessments are a result of the TSS impairment and would be considered addressed
through the TSS impairment by the MPCA.
20. The TMDL Study states that the primary cause of the TSS impairment is "likely
streambank and near-channel erosion of sediment." Much of Riley Creek has an incised
channel with relatively little floodplain and sparse riparian vegetation due to the dense
forest canopy cover. The lack of vegetation along the Creek, minimal floodplain, sandy
native soils, and steep gradient of the creek all contribute to bank and bed erosion that
facilitates sediment transport. Regarding TSS, the study further explains that, "much of the
reduction will need to come from near-channel sources (e.g., streambank erosion)."
21. Over the past 10 years, the City and Riley Purgatory Bluff Creek Watershed District
("RPBCWD") have participated in several streambank stabilization and creek restoration
projects along Riley Creek. The TSS data from the Watershed Outlet Monitoring Program
("WOMP") station managed by the Metropolitan Council and the City have shown that the
TSS concentrations in the Creek have decreased as streambank stabilization and creek
restoration projects have occurred in the watershed. This is despite additional residential
development in the watershed. More recent projects, such as Reeder Ridge and the
realignment of Eden Prairie Road, have also employed similar infiltration stormwater
management best management practices ("BMPs") to reduce runoff to the Creek and treat
4
for pollutants. The WOMP sampling has not shown increasing TSS trends in the Creek
since these projects were completed.
22. The TMDL Study acknowledges that reductions in runoff volume from municipal storm
sewer will result in lesser peak flows and potential for erosion in the Creek. The Project
proposes to use stormwater BMPs to retain stormwater on-site for infiltration and remove
stormwater pollutants including TSS. The proposed infiltration basins for the Project are
sized to retain an equivalent volume of 1.1-inches multiplied by the proposed impervious
surfaces. Based on the Minimal Impact Design Standards ("MIDS") program from the
MPCA, this volume will result in on-site retention of 90 percent of annual rain events.
Additionally, MIDS Calculator modeling submitted in the Stormwater Management Report
has shown that the annual runoff volume and TSS loading from the Project site will not
exceed that of its existing condition. Lastly, RPBCWD Rules stipulate that the rate of
runoff cannot increase at all discharge points on the site. These factors demonstrate that
although the Project will have a net increase in impervious surface, the BMPs will reduce
runoff volumes and TSS loading to the Creek and make it unlikely to contribute to the high
flow conditions that lead to erosion in the Creek.
23. Based on WOMP sampling data, the E. coli levels in the Creek have been variable over
time, but have recently shown a slight upward trend. E. Coli concentrations in the Creek
have been linked to wildlife, congregations of waterfowl, and improper management of pet
waste. The MPCA Stormwater Manual states, "Bacteria removal is assumed to be 100
percent for all water that infiltrates." Given the Project's runoff from 90 percent of storms
will be retained within the basins for infiltration, the majority of E. coli loading from the
Project's storm sewer systems will be treated and not reach the Creek. Additionally, the
MPCA Stormwater Manual identifies pet waste management ordinances and education as
highly effective methods in controlling or reducing bacterial pollution. The City has a pet
waste ordinance in place and is the process of expanding educational programs on this
subject. The Project's proposed basins are also designed to draw down within 48 hours,
making them unlikely to become frequented by large congregations of waterfowl.
24. While landslides are a potential risk in any environment where there are sandy soils (or
other susceptible soils) together with the presence of water that could saturate the soils, the
City requires a geotechnical analysis for any development to provide engineered solutions
for soil conditions, site grading, retaining wall construction, and drainage control for
retaining walls. Based on Braun Intertec's Geotechnical Evaluation Report for this Project,
recommendations were made for various site conditions such as overall site grading, reuse
of on-site soils, effects of groundwater, excavated slopes, filling on slopes, dewatering,
retaining walls (drainage control; selection, placement, and compaction of backfill; and
configuring and resisting lateral loads), as well as structure and pavement
recommendations. In addition to these geotechnical recommendations, the City is requiring
that surface drainage near retaining walls be routed away or designed to capture and direct
runoff from a 100-year storm event toward storm drainage structures (which will reduce
the risk of drainage overtopping the retaining walls). A drain tile system will also be
installed behind the retaining walls to release any water that collects behind the walls. All
retaining walls over four feet in height will require a building permit from the City's
Building Inspection Division.
5
25. Since this Project site is within a Shoreland Management Zone, City Code 11.50 requires
a bluff determination, consistent with DNR regulations. A "bluff' is defined as a rise in
elevation of at least 25 feet above the ordinary high water level and with a grade of slope
at or over 30%. A bluff was identified on the Project site, which means that any structures
must be setback at least 20 feet beyond the top of the bluff. The entire bluff and bluff
setback zone is located with Outlot D, which will be deeded to the City to be preserved in
perpetuity.
26. The trees and native vegetation preserved within Outlot D and the wetland buffer will
continue to provide protection to adjacent water resources. These buffers help filter out
stormwater pollutants and prevent erosion. The natural buffers provided by the Project are
in excess of those required by City Code. Additionally, the proposed stormwater BMPs
will serve to provide additional treatment of stormwater on the site. Monuments will
demarcate areas to be preserved as buffers to prevent them from being encroached upon.
27. Based on the combination of these facts, the Project's environmental effect on Riley Creek
is not significant and may in fact improve some conditions beyond where they exist today.
Cumulative potential effects
28. There is no evidence of significant cumulative potential effects relating to impairment of
Riley Creek. Despite additional residential development in the Creek watershed since the
WOMP sampling began in 1999, the majority of stormwater pollutants have been stable or
decreased over this time. The decrease in TSS in the Creek is likely resultant of on-going
creek restoration and stabilization practices. Furthermore, the WOMP report has noted that
pollutants commonly associated with fertilizer use (orthophosphates, nitrates, ammonia,
and Total Kjeldahl Nitrogen) have decreased as land use has transitioned from agricultural
to residential.
Mitigation by ongoing regulatory authority
29. The permanent stormwater management BMPs associated with the Project will be
maintained by the City. The City has watershed district-wide Maintenance Agreement with
the RPBCWD that stipulates that the BMPs must be kept in working order through routine
and major maintenance activities.
30. The City, in partnership with RPBCWD, will also continue to work on Creek restoration
and streambank stabilization projects that will work toward bringing TSS concentrations
in the Creek into compliance with the standards identified in the TMDL Study. As part of
the most recent 2020 MS4 Permit Application, the City is working toward establishing a
compliance schedule for the TSS TDML for the Creek. As such, the City will also continue
to implement BMPs throughout the Creek watershed to minimize stormwater pollution.
This includes but is not limited to pet waste management education programs, waterfowl
management, retrofitting of existing structural stormwater BMPs, and cleaning of existing
stormwater ponds in the watershed.
6
31. City and RPBCWD rules and regulations regarding stormwater management will continue
to apply to this Project and to future development or redevelopment within the Creek's
watershed.
Other studies
32. Studies that describe how environmental effects on Riley Creek can be anticipated and
controlled include the following, which have been considered by the Council and are
incorporated herein by reference: 2020 WOMP Riley Creek Monitoring Results; Lower
Minnesota River Watershed Total Maximum Daily Load; MPCA Stormwater Manual;
Braun Intertec's Geotechnical Evaluation Report for the Standal Property dated October
10, 2019; and Braun Intertec' s Supplemental Soil Borings -Standal Property dated March
5, 2020.
Fredrick-Miller Spring
33. The petition alleges that the Project will have a direct negative effect on the water quality
of the Fredrick-Miller Spring (the "Spring") and may potentially lead to the elimination of
the Spring. The petition cites heritage, testing, and water quality degradation as evidence
demonstrating potential for significant environmental effects.
34. As a locally designated Historic Preservation Site, the Spring is governed by Section 11.05
of the City Code. This portion of the City Code seeks to safeguard the heritage of the City,
promote the preservation and continued use of historic sites, and foster civic pride. Section
11.05 outlines the process of public review and the criteria that must be met if alterations,
buildings, or demolition are proposed for a Historic Preservation Site. The Fredrick-Miller
Spring Historic Preservation Site is not located within the Project boundaries. No changes
are proposed to the Historic Preservation Site.
35. Minnesota Statutes Chapter l 16D establishes a statewide environmental policy that is
intended, among other things, to preserve natural resources. The statewide definition of
"natural resources" includes "historical resources." Minn. Stat. § 1168.02, subd. 4. The
petition alleges that this reference endorses the request for the preparation of an EA W. The
Council finds that this general definition that applies statewide does not provide evidence
that this Project will cause significant environmental impact to the Spring.
Tvpe. extent. and reversibilitv of environmental effects:
36. According to the Summit Envirosolutions Report titled "Results of Impact Assessment
Fredrick-Miller Spring Eden Prairie, MN" dated April 9, 2021 ("Summit Report"),
Frederick-Miller Spring is a seep, not an artesian spring, that emerges from the side of a
bluff on the west side of County State Aid Highway 4 ("Spring Road") which is west of
Riley Creek and west of the Project. Water from the seep is collected in an underground
cistern and is then piped down the remaining bluff and under Spring Road to a trough in a
parking lot on City-owned property west of Riley Creek.
37. The Summit Report identified the Spring's recharge area by compiling published geologic
information in the area within a Geographic Information System (GIS), performing field
7
reconnaissance to evaluate the current conditions and hydro geologic setting of the Spring,
obtaining surveyed elevations of the Spring and proposed Project features, and preparing a
summary of findings and conclusions. Based on the published data, the field
reconnaissance, and Summit Envirosolutions' experience in similar geologic terrains, the
Summit Report concluded that the entire recharge area for the Fredrick-Miller Spring is
located west of Spring Road and that activities associated with the Project will have no
impact on the quantity or quality of the water recharging the Spring.
38. The Summit Report also reviewed Dr. E. Calvin Alexander's "Steps to Protect Water
Quality of Fredrick-Miller Spring," which was included with the petition. Summit
Envirosolutions disagreed with Dr. Alexander's analysis by stating:
I do not think Dr. Alexander was given all the information we have
regarding the recharge area of the spring. The oral history is clear that the
original seep location is located up the east-facing hill west of the current
location and was outfitted with an old bathtub and piping to convey the
water first to an area west of Spring Road and then under the road to the
current location. I do not believe Dr. Alexander was given that information,
since he suggests that the initial recharge area should be ' ... all of the land
and surface water bodies at elevation above the Fredrick-Miller Spring ... '.
If he knew the original seep location is located on the east-facing hill west
of Spring Road on what is an isolated topographical feature, he would likely
not suggest a 2-mile area for further study. The other key pieces of
information that are not referenced in his document are the surficial geology
map (Geologic Atlas of Hennepin County Balaban, N.H., 1989) that shows
outwash surrounded (and underlain) by till and the 18 drilling logs (obtained
from the Minnesota Well Index) that enabled us to interpolate a clay surface
that is the likely mechanism for the Spring recharge. I think if Dr. Alexander
had this same information, he would likely not use the term "artesian
spring", because the flow produced at the Spring discharge outlet is gravity
drainage from a "perched" water table that is unconfined.
39. In 2005, an Environmental Assessment Worksheet ("2005 EAW") was completed by the
City for its Hennepin Village Roadway Alternative project. The 2005 EA W evaluated a
number of alternatives for the layout and construction of a new collector roadway servicing
several residential neighborhoods in the southcentral portion of Eden Prairie. The 2005
EA W considered a number of the roadway alternatives that had potentially significant
irreversible environmental impacts because the proposed roadway crossed environmentally
sensitive lands such as bluffs, Riley Creek, wetlands, the Frederick-Miller Spring recharge
area, known archeological sites, recorded burial areas, and other unique resources. The
EA W concluded that the Spring "originates in the bluff area directly west across Spring
Road from the current spring trough location. It is likely that the Miller Spring ground
watershed is west and northwest of the spring." This conclusion is consistent with the
Summit Envirosolutions report and indicates the Project will not impact the Spring
recharge area.
8
40. The Council finds the Summit Report and the 2005 EA W to be more credible than the
opinion of Dr. Alexander as to the type and nature of any environmental effects that the
Project may have on the Spring.
41. Historical City monthly testing of Nitrates at the Spring shows a decrease in average
Nitrates as agricultural properties have developed into residential single-family housing.
This is likely due to stormwater runoff management facilities being constructed during
development and the reduction in Nitrates from farm animal confinements, manure
spreading, and agricultural fertilizer use. The polynomial trendline of Nitrate values
between July 2009 and April 2021, the period for which testing results exist, shows a
decrease from highs of approximately 3.8 parts per million (ppm) in 2009 through 2011 to
lows of 1.8 ppm in 2020 through 2021. The United States Environmental Protection
Agency and the Minnesota Department of Health list Nitrate concentrations of 10.0 ppm
or lower as safe for potable drinking water sources. Nitrate is a naturally occurring
compound and levels around 3 .0 ppm are considered safe and customary for well water
sources. For comparison purposes, the City tested several types of store-bought bottled
water on April 8, 2021. These results found Nitrate levels of 3.9 ppm, 4.0 ppm, and 6.4
ppm for three popular bottled water brands, which were all still below federal and state
maximum contaminant levels. Because the Spring's Nitrate test results are consistently
well within safe drinking water standards, and in fact seem to suggest an improvement over
time as residential development has displaced agricultural uses, and because the recharge
area for the Spring has no relation to the Project, there is no potential for significant
environmental effects related to the water quality of the Spring from the Project.
42. Historical City monthly testing of total Coliform at the Spring from July 2009 to April
2021 shows two instances of a positive sample. Those tests detected the presence of
Coliform on August 1, 2016 and again on August 2, 2016. Because the samples are taken
directly from the spigot of the communal-use Spring discharge pipe, it is very possible the
bacterial Coliform came from a user of the Spring as a hand, used bottle, jug, or other object
touched the end of the pipe while collecting water. These are the only two records from the
past twelve years of testing at the Spring where the presence of Coliform was detected.
Because the Project will not impact the recharge area or the distribution point of the Spring
there does not appear to be a correlation between the two and no environmental impacts
are expected.
Cumulative potential effects
43. There is no evidence of significant cumulative potential effects relating to impairment or
the potential elimination of the Spring. To the contrary, data is showing Spring water
quality is improving as land use changes from agricultural use to residential use. All
analysis done on the Spring and its recharge area has demonstrated that the Project will not
have an environmental effect on the Spring, significant or otherwise.
44. The Project nonetheless proposes to take steps to protect nearby water resources by deeding
sensitive lands that harbor Riley Creek, a wooded forest, wetland, creek buffers, and bluffs
into an outlot to be deeded to the City for preservation as a natural landscape environment.
This naturally preserved outlot is 8.79 acres, which comprises 31 % of the total Project area.
9
This outlot serves as a buffer between the Spring discharge point and the homes proposed
within the Project. The Project is also proposing to meet all City and watershed district
requirements for water resource protection during and after construction.
Mitigation bv ongoing regulatory authority
45. The City anticipates future development that is within the Spring recharge area to the west,
and will take necessary steps to ensure this water resource is protected through our various
environmental controls. RPBCWD will do the same as development and land disturbing
activity applications are submitted and reviewed for appropriateness.
46. The City plans to continue testing the Spring on a monthly basis for Nitrates and total
Coliform.
Other studies
47. Studies that describe how environmental effects on the Spring can be anticipated and
controlled include the following, which have been considered by the Council and are
incorporated herein by reference: Summit Envirosolutions Report titled "Results oflmpact
Assessment Fredrick-Miller Spring Eden Prairie, MN" dated April 9, 2021, and the
Environmental Assessment Worksheet for the Hennepin Village Roadway Alternatives
dated February 2005.
Health, Safety and Quality of Life
48. The petition alleges that the Project will have a general negative impact on health, safety,
and quality of life. Specifically, the petition cites the potential negative impact on
surrounding developments to the north and east, increased traffic, noise, and air quality
impacts, and road safety and sight distance risks on Spring Road.
Type, extent, and reversibility of environmental effects
49. As is mentioned in the findings of fact above under the Biodiversity of Project Site, Riley
Creek, and Frederick-Miller Spring categories, the extent of the Project's environmental
effects are minimal and even show potential for improving existing conditions.
50. The addition of 50 residential homes within the 27.51 acre Project area will result in
minimal increases in noise and air pollution above current conditions. The proposed density
of homes in the Project area is 1.8 dwelling units per acre, which is well below the
allowable density of 5 units per acre for the zoning district. This density also is much lower
than the existing densities in nearby residential neighborhoods to the east and north. Also,
according to the Project proposer, the energy efficiency of the homes being proposed in
the Project area are 77-83% more energy efficient than typical resale homes which will
result in lower building emissions. Overall, the Project will generate very minimal
increases in noise and air pollution.
51. Flying Cloud Airport is situated 825 feet from the property line of the Project. Flying Cloud
Airport is a reliever airport for the Minneapolis St. Paul International Airport and serves as
10
a popular hub for corporate business jets, turbo-props, and helicopters. The airport has an
FAA-operated control tower and an instrument landing system. The tower operates daily
in the winter from 7 a.m. to 9 p.m., staying open an extra hour until 10 p.m. in summer. In
2018 there were 364 aircraft based at Flying Cloud Airport resulting in 88,762 landings
and takeoffs. Traffic, noise, and emissions generated from the Project will be a fraction of
those generated from the adjacent airport.
52. The adjacent roadways have been designed and constructed to anticipate the increased
traffic that would be generated by the Project. The Project is expected to generate 4 72
average daily trips ("ADT"). The adjacent roadway, Spring Road, is classified by the City's
Comprehensive Plan as an A-Minor Expander and has the capacity to accommodate the
traffic generated by the Project. The roadway was designed and constructed for 10,000
ADT. With left tum lanes, the capacity increases to 17,000 ADT. Current average daily
trips on Spring Road are 4400 ADT north of Charlson Road and 1800 ADT south of
Charlson Road. The roadway classifications in the Project area and any associated impacts
are consistent with the development levels identified in the City's Comprehensive Plan.
The petition provides general information regarding traffic impacts on a national level. It
provides no evidence of significant environmental effects resulting from the traffic that the
Project will generate.
53. Spack Solutions evaluated existing sightlines at the Project's access point to Spring Road
under current conditions. According Spack Solutions, "sufficient sight distance is provided
for passenger vehicles and single-unit trucks to safely complete both left and right-turning
movements from the proposed access." Spack Solutions used national standards adopted
by the American Association of State Highway and Transportation Officials (AASHTO)
in performing this sight-light analysis. AASHTO is a nonprofit, nonpartisan association
representing highway and transportation departments across the 50 states, the District of
Columbia, and Puerto Rico, and is a standards setting body which publishes specifications,
test protocols, and guidelines that are used in highway design and construction throughout
the United States. Spack Solutions goes on to say, "Tree-trimming along Spring Road will
provide more sight distance to drivers, specifically to the south." Because the Project
proposes to construction a 15-foot wide boulevard area on the east side of Spring Road for
a future pedestrian and bicycle trail, the sight lines will be dramatically improved over the
conditions that exist today. Additionally, improvements along Spring Road made by the
Project will be overseen by Hennepin County's Transportation Department to ensure all
applicable safety standards are met (see Hennepin County comment letter).
54. Considering all these factors collectively, there is no potential for significant environmental
effects related to traffic, safety, noise, or air pollution as a result of the Project.
Cumulative potential effects
55. There is no evidence of significant cumulative potential effects relating to traffic, safety,
noise, or air pollution as a result of the Project.
11
Mitigation by ongoing regulatory authority
56. Spring Road roadway safety, intersection design, and sightline requirements will be
approved through Hennepin County's Transportation Department permitting process. The
County will evaluate access design and post construction sightlines to ensure conformance
with adopted performance standards.
Other studies
57. Studies that describe how environmental effects relating to traffic, safety, noise, or air
pollution can be anticipated and controlled include the following, which have been
considered by the Council and are incorporated herein by reference: Spack Solutions -
Technical Memorandum -Traffic Assessment -Standal Concept dated November 7, 2019;
Alliant Memorandum -Noble Hill Development dated February 10, 2021; and Hennepin
County -Preliminary Plat Review Letter dated March 1, 2021.
Summary
58. The evidence presented to and considered by the Council does not demonstrate that,
because of the nature or location of the Project, the Project may have the potential for
significant environmental effects. Any environmental effects that may result from the
Project are not significant. Areas of potential concern will be monitored and negative
effects mitigated.
59. Any cumulative potential effects of the Project are not significant as demonstrated in these
findings of fact. The potential effects of the project when reviewed in connection with the
other potential effects in the environmentally relevant area that might reasonably be
expected to affect the same environmental resources are not significant. Existing
developments within the vicinity of the Project have been reviewed and constructed
consistent with City and Watershed District requirements in effect at the time of
development. The developer of the Project will be required to obtain and comply with all
necessary permitting and approval processes required by the City and Watershed District
that will address mitigation measures as appropriate. The Project minimizes any potential
effects by preserving natural resources areas in Outlet D of the Project area.
60. The petition alleges that the Project is part of a connected and phased action that requires
individual environmental review. Specifically, the petition alleges that the Project "is
collectively part of a large existing or planned network ... for which the City has attempted
to separate the approvals in order to make a determinate that no environmental review is
needed." In determining whether a project meets the threshold for a mandatory EA W,
Minnesota Administrative Rule 4410.4300, subpart 1, requires consideration in total of
"[m]ultiple projects and multiple stages of a single project that are connected actions or
phased actions." Beyond these unsupported allegations, Petitioners provide no evidence
that the Project is part of a connected action or phased action that is subject to a mandatory
EAW.
12
DECISION
Based upon the above findings of fact, the Council hereby concludes that the evidence
presented fails to demonstrate that the Project may have the potential for significant environmental
effects. The petition for preparation of an EA W for the Project is therefore DENIED.
ADOPTED by the Eden Prairie City Council this 4th day of May, 2021.
