2nd Addition building and require the vegetative covering of fill within the Floodway
District (F-l) directly south of the proposed middle school (see attached Erik Peters
memo, April 3, 1998). The project will involve the extraction of material from the
floodway to compensate for the filling of the floodplain to provide an adequate building
site for the proposed addition to the middle school
Preliminary plans indicate that the School District proposes to retain the existing 100-
year flood stage at an elevation of 899' after work is completed on the site. This will
meet the standards for a Floodway conditional use in Section 10-10-4 (D)-I, requiring
that any obstruction or storage of materials within the floodway may not cause any
increase in the stage of the regional flood or cause an increase in flood damages in the
reach or reaches affected.
Section 10-10-4 (C)-2 of the City Code requires conditional use approval for the
extraction of material within a floodway district. Since the extraction of material within
the floodway district is proposed, the School District is seeking a conditional use and
complying with the City Code.
Section 10-10-4 (D)-2 requires that any fill placed in the floodway district be protected
from erosion by vegetative cover, mulching, riprap or other acceptable methods. The
School District intends to follow the recommendations made by Erik Peters in his memo
dated March 5, 1998. On page 4 in the Vermillion River Floodplain and Water Quality
Improvements for Runoff section, Mr. Peters recommends that vegetative buffers and
infiltration trenches be used to improve the quality of runoff leaving the site. He also
recommends that a variety of plant types needs to be planted beginning with wetland
vegetation in the lower elevations and native prairie grasses along the edge of the bus
route roadway. Mr. Peters further states in his memo dated March 31, 1998, that the
vegetation of the floodplain could also be used as an outdoor classroom for the school.
With the introduction of plant species within the floodway district area by the School
District, City staff has determined that compliance with the code will be observed.
Requested Action:
Staff recommends the approval of the conditional use for the extraction of material and
requirement of vegetative covering of any fill proposed within the floodway district.

Project Name: Farmington 6-7 Middle School

File No: 141-1061
From: Erik Peters
Date: April 3, 1998
Re: Proposed construction work within the 1 DO-year floodplain of the Vermillion River
Remarks: The current preliminary site grading plans for the 6-7 Middle School propose excavation
within the 1 DO-year floodplain. The primary purpose is to mitigate for a limited amount of floodplain fill
associated with the proposed 6-7 Middle School building.
The work currently proposed within the 1 DO-year floodplain associated with the 6-7 Middle School has been
reviewed to ensure that the floodplain retains its existing capacity to pass the 1 DO-year flow event. The
1 DO-year flood stage will remain at its current elevation of 899' (based on Flood Insurance Studies) once
work is complete. The current plans call for fill within the 1 DO-year floodplain of approximately 1,676 cubic
yards (assuming the future buildout of the 6-7 school bus loading corral). The excavation within the
floodplain is proposed to be approximately 4,980 cubic yards. An excess of 3,304 cubic yards of earth will
be removed from the area within the 1 DO-year floodplain. These calculations were submitted by Philip
Behrend of A TS&R (plans and cales dated 3/13/98). These numbers are preliminary and should be
verified once final site grading plans are submitted.
The school district anticipates that they would like to expand the bus corral of the existing middle school
some time in the future. Expansion of the bus corral will likely occur within the 1 DO-year floodplain and
result in some fill within the floodplain. The school district would like to "bank" the excess excavation within
the floodplain associated with the 6-7 Middle School for use as compensation for any fill associated the
future expansion of the existing middle school bus corral. Depending on the extent of fill and where the fill
occurs, the proposal to swap future fill for prior excavation may be suitable. A recommendation as to
whether a swap is applicable can only be made once plans are finalized for the future expansion of the bus
corral.

Re: Recommendation regarding soils and seeding of infiltration areas to be used to improve the quality of
runoff.
Remarks: Based on the conversation we had regarding the grading and seeding the proposed Middle
School addition, we have the following recommendations:
Soils:
1. Infiltration basins (located adjacent to 20Sth street and in northeast corner of school property):
These areas have previously been recommended to have the topsoil, which is a lean clay, removed to
reach the underlying sand. Where topsoil has been removed below the bottom of the infiltration basins
. (897'), we recommended that clean sands be used to bring up the bottom of the basins to within 4 - 8
inches of the final elevation. The upper 4 - 8 inches of soil we recommend to be topsoil taken from onsite.
We feel that the topSOil will allow for adequate infiltration of water and aid in the establishment of
permanent vegetative cover.
2. Vermillion River Floodplain and buffer zone:
This area has been designed to incorporate infiltration trenches and buffers for water quality protection.
We believe that the current grading plans (2/2/98), showing partial excavation of the topsoil within the
floodplain, will adequately permit infiltration of surface runoff once vegetation has been established. It is
not recommended that the sands underneath the topsoil be mined for use elsewhere on site unless the
sands are replaced with clean sands from offsite.
For both areas it is preferable to utilize existing topsoil rather than "amended soil" for several reasons.
Topsoil contains beneficial organic matter and microorganisms that help accomplish a number of goals.
Among these are: greater resistance to drought, improved establishment of native species and reduced
sheet erosion due to the existing aggregate structure. We feel that the lean clay topsoil will allow desired

infiltration as a thin (4-8 inch) top cover. Subsoil materials generally do not possess alii of these benficial
characteristics.
Vegetation (all areas):
The infiltration and vegetative butter areas will likely experience a wide variety of conditions, from
saturation of soil to droughty conditions. Given this wide fluctuation in conditions, we recommend that
standard Mn/DOT mixes for grasses and forbs are used. Using these mixes will help to minimize costs
while providing for effective long-term stability of an adaptable vegetative cover and provide aesthetic
improvement of the site. For wetter portions of the site that will experience extended periods of saturated
soil we recommend Mn/DOT standard mix 25A. For areas that will experience little or no inundation
(vegetative buffers and upland areas), we recommend Mn/DOT mix 15A. A standard wet site Mn/DOT
flowering plant (forb) mix and SE Region forb mix is recommended to be included in both mixes
respectively.
The SE Region Forb mix would likely benefit from being customized based on the amount of money
available and the intended use of the project site. For instance, some species in the SE Region Forb mix
have an affinity for drier sites. Substituting species adapted to mesic/wet conditions would provide greater
. cost effectiveness in the seeding portion of the project. If desired, additional recommendations can be
provided.
Since the area around the school is of high visibility and has a great potential to be used as an outdoor
classroom, we recommend that appropriate flowering plants be used to the greatest extent possible.
Outdoor classrooms are an excellent experiential venue for students to carry out experiments, observe
plants and animals, and monitor the intended functionality of a site. If adequate funds are not available
within this project to reach such a goal, the school may wish to apply for grant monies that exist within the
metropolitan area intended to support efforts of this type.

Date: March 5, 1998
Re: Drainage review of plans (submitted on 2/2/98) and summary of meeting on 2/3/98 with the school
board and A TS&R engineering staff regarding drainage issues.
Remarks: The site to be developed poses some design challenges with regards to drainage and water
quality protection. The first challenge is the existing on-site topsoil which is p'redominantly a lean clay. The
runoff from clay soils is very high, especially in developed areas where the surface is graded to drain
quickly and turf grass is the predominant vegetation. The high runoff from the site will result in larger than
typical water quality ponds.
The second challenge is the high groundwater table (approximately 894'). To protect groundwater from
direct inputs of surface water runoff, the bottom of the ponds are recommended to be at least 3' above the
groundwater table. The pond bottom may be lowered a couple of feet if the bottom is sealed with an
. impervious liner. The limited depth of excavation allowable on this site affects the construction of water
quality ponds. Unless a substantial amount of fill is brought onto the site, the wet storage volume and
minimum average depth requirements for water quality ponds will not be able to be met.
The design challenges posed by this site necessitate the investigation into alternative best management
practices to improve runoff leaving the site and water quality protection for the Vermillion River and the
adjacent wetlands. The River is a protected waterbody and the wetlands are some of the highest quality
identified on the Wetland and Waterbody Classification Map in the Cities' Surface Water Management Plan
(SWMP). The recommended alternative best management practices are the promotion of infiltration and
vegetative buffers/filters. To help ensure the long term success of the alternative best management
practices, the Farmington School District is encouraged to develop a vegetation management plan for the
Farmington Middle School. The vegetation management plan is recommended to contain provisions
limiting the use of fertilizers (phosphorus-free only), pesticides, and herbicides, and guidance on their
application and storage.
The site contains a significant amount of sandy soil underneath the clay topsoil. These sandy soils are
suitable for use in the construction of infiltration basins for water quality purposes. The infiltration basins, if
designed and constructed properly, hold the potential to meet and possibly surpass the benefits of typical
wet detention ponds. To ensure the infiltration basin will function properly, the site must be kept clean of
. on-site soils (specifically the lean clay topsoil) during the entire construction period. The pore spaces

The fields adjacent to the infiltration basin should be raised 2' to 3' higher in order to lessen the extent
and frequency of inundation by runoff into the infiltration basin. Raising the fields may introduce
drainage issues with the properties adjacent to the proposed fields that will need resolution.
Vermillion River Floodplain and Water Quality Improvements for Runoff:
After reviewing the submitted plans and considering water quality issues, the proposal to create a small
ponding basin within the floodplain is not recommended. The pond would not be large enough to meet the
protection requirements required for the Vermillion River and its wetlands. Instead it is recommended that
vegetative buffers and infiltration trenches be used to improve the quality of runoff leaving the site. The
result would be that the entire area between the bus road and the wetlands associated with the Vermillion
River are recommended to become one large vegetative buffer area. The use of this area for overland
water quality improvement of runoff prior to inflow into the Vermillion River could meet the requirements of
the SWMP. The area could also become a natural science area for the schools
1. It is recommended the grading plan include the future bus corral planned for the south side of the
school. This will assist in the proper design and placement of the proposed vegetative buffers and
infiltration trenches so they will be effective now and in the future. The grading of the floodplain is
recommended to be changed to look more natural with some undulation. As currently designed, it
looks unnaturally uniform. The grading plan should show compensation for fill within the floodplain at
. the school building and the future bus corral.
2. The proposed berm and outlet along the southern edge of the property would no be longer necessary.
3. A variety of plant types will need to be planted beginning with wetland vegetation in the lower elevations
and native prairie grasses along the edge of the road. The type of native vegetation selected and their
placement on the site will need to match their preferred environment. The slope of the site and
resulting changes in the local environment will result in some differentiation in vegetation types.
4. Multiple vegetative infiltration trenches are recommended to be constructed along and parallel to the
bus road. The intent of the trenches is to slow the rate of runoff, promote sheet flow rather than
concentrated flow of runoff, encourage infiltration of runoff into the soil and filtration through the use of
vegetation (grasses). The trenches are recommended to be constructed using earthen berms,
approximately l' in height. The top of the earth berms should be fairly level to promote dispersion of
flow over the berms. To further the promotion of infiltration, the bottoms of the trenches may be lined
with pervious soils/gravel under a thin layer of topsoil. Further recommendations to their design can be
provided.
5. The storm sewer carrying runoff from the roof is recommended to discharge into the first vegetative
filtration trench farthest from the river. The outlet should be constructed to direct flow along the filtration

trench to promote sheet flow by using the berms to disperse flow. Energy dissipation at the outlet will
likely be necessary.
Northwest Corner Pond/Seepage Area:
As proposed, the pond basin may be designed to function as an infiltration basin for water quality
purposes. The clay topsoil within the basin will be removed and replaced with clean sand up to the 897'
contour. However, because runoff into the pond will not have gone through a sedimentation basin, the
pond bottom may seal and lose its infiltration capacity over time. How long it will take for the pond bottom
to seal is unknown. The behavior of this pond should be observed over time and it may provide useful data
that could be used in future pond design in the City.
1. The 1 DO-year peak discharge from the pond is recommended to be restricted to match existing
conditions or the capacity of the downstream ditch whichever is more restrictive.
.
2. Assuming the pond will be designed as an infiltration basin, the required storage volume below the
outlet elevation is the runoff from a 5-year storm event (1 acre-foot). To maintain the existing discharge
to existing conditions (approximately 5 cfs) the recommended outlet is a drop inlet structure (elevation
899') with a 12" culvert (invert at 898') exiting the structure. Assuming the bottom of the pond is no
longer infiltrating and the starting water surface is at 899', the 1 DO-year HWL will be approximately 900'
with a peak discharge of 5 cfs. It is assumed that there is an additional 0.9 acre.feet of storage
between the 899' and 900' contours in estimating the HWL elevation. The peak discharge is a
somewhat high, however, since the pond should, for the most, part function as designed, there won't be
many occurrences where the outlet is used.
3. The ponding basin could be designed as a wet pond. Using the PONDNET model, the wet storage
volume required to meet water quality criteria is 1.3 acre-feet. The drawback to this option is that the
minimum average depth criterion of 3' - 4' depending on the pond size is not likely to be met. The
purpose of the minimum average depth requirement is to avoid the re-suspension of sediment from the
pond bottom due to inflow into the pond. An infiltration basin would provide better treatment of runoff
water, assuming the basin works as designed. The benefit to this option is slightly better rate control
(estimated peak discharge of 3 cfs). An aquatic/safety bench and outlet skimmer structure will need to
be provided should the pond be designed as a wet pond.
This pond could be designed using either method described above. However, it would be of interest to
construct the pond as an infiltration basin and observe the behavior of the pond over time. The use of
infiltration ponds may become more prevalent within the City, especially along the designated trout
streams. This appears to be a good location for an infiltration pond and it could provide useful data for
future designs in the City.

TO:
City Planning Commission
FROM:
Lee Smick, Planning Coordinator
DATE:
April 14, 1998
RE:
Equipment and maintenance storage
definition
Comments:
Member Rotty requested that the Planning staff review the equipment and maintenance
storage definition to further detail the definition. The equipment and maintenance storage
definition has recently been discussed concerning the Bongard Trucking site.
The ordinance defines equipment and maintenance storage as a structure for maintenance;
repair or storage of equipment on property owned by the owner of said equipment (see
attached definition). Equipment and maintenance storage is a conditional use in the A-I,
A-2 and C-l districts (see attached permitted and conditional uses).
As witnessed by the permitted and conditional uses listed, equipment and storage yards
are also mentioned as a conditional use in B-2 and B-3 districts, however, there is no
definition of this use in the code. This use seems to relate to equipment and storage
yards, rather than a structure for maintenance, repair or storage of equipment.
The Planning staffhas received copies of ordinances from several nearby communities to
review their definitions for equipment and maintenance storage. The information below
demonstrates differences in interpretations for storage and may assist in revising the
City's definition.
City of Eagan - Outdoor storage - means to stock, keep, sell or trade outside a
commercial or industrial building any items of merchandise, supplies, materials, finished
goods, inventory or other movable property or motor vehicles. For purposes of this
definition and the regulation of outdoor storage, a temporary outdoor event and seasonal
outdoor sale shall not constitute outdoor storage.
Only permitted in industrial, general business and community shopping center districts.
Storage items are to be placed within an enclosure area attached to the principal building
and constructed with aesthetically compatible materials. The storage area shall be located
in the side or rear yard and not encroach into the front yard setback area.
Citlj of Farmington 325 Oak Street · Farmington, MN 55024 · (612) 1163.7111 · Falf (612) 1163-2591
.
.
.
City of Burnsville - Outdoor storage - The keeping, in an unenclosed area, of any goods,
junk, material, merchandise, or vehicles in the same place for more than twenty-four
hours.
As witnessed by the information, the City's definition of equipment and maintenance
storage differs somewhat from the communities researched because these communities
did not have this type of use defined.
After discussions with the Community Development Director and Member Rotty, it is
apparent that the definition needs to be further defined and additional research should be
done in other communities to determine the most appropriate definition for the City.
As a side note, please feel free to direct staff in other tasks that you feel need revision. As
time permits, staff will perform revisions as requested.
Requested Action:
Direct staff to further study the equipment and maintenance storage definition in order to
further define it to meet standards within the City.

RE:
Prairie Creek East Schematic PUD
The City received comments from various agencies on the comment period due date of
March 25 concerning the Prairie Creek East EA W. Attached is a compilation of the
comments received and has been divided into three categories: EA W Requirements,
Design Details and City Requirements. As witnessed by the amount of comments
generated from the agencies (see attached comments), it is apparent that more
information is required before a decision by the RGU (City of Farmington) can be made.
The RGU has 30 days to review the comments made by the agencies and make a
decision. The decision period for the RGU will expire on April 25th. The RGU has three
options in determining a decision for the EA W. Those include a positive declaration, a
negative declaration or postponement of the decision on the need for an EIS in order to
obtain lacking information.
City staff, commenting agencies and the developer met on April 6th to discuss the
comments and the information lacking in the EA W. At this meeting it was determined
that a WCA Technical Evaluation Panel (TEC) needs to determine the existing vegetative
cover for wetland classification, wildlife habitat and overall quality of the drainage ditch
to evaluate whether the ditch should be disturbed or not. Since the TEC requires time to
review the drainage ditch and the developer requires time to address comments, the City
will request a 30-day time extension to the decision period from the EQB to May 25th.
Since additional time is required for a decision on the EA W to be made, City staff
recommends that the Prairie Creek East Schematic PUD be continued indefinitely
pending the outcome of the EA W. Adjacent property owners will be re-notified if the
schematic PUD is scheduled on the Planning Commission agenda for review.

NOTICE OF MEETING FOR
PRAIRIE CREEK EAST EA W REVIE\V
The City Staff of the City of Fannington have requested a meeting to discuss the Prairie
Creek East EA W to be held on April 6, 1998 at 3:00 PM in the Council Chambers of
Farmington City Hall, 325 Oak Street, Farmington Minnesota. Attendees will include
City Staff, the City Attorney, Bonestroo Engineers, Progress Land Company, West\\'ood
Engineers, Dakota County Soil & Water Conservation District, Empire's Engineer -
Bolton & Menk and Montgomery Watson, engineers for the Vermillion River Watershed
Management Organization.
The attached information is a compilation of comments made by various agencies for the
Prairie Creek East EA W. The listing is divided into three categories exhibiting EA W
Requirements, Design Details and City Requirements. The meeting will give the
developer and his engineers an opportunity to respond to the comments and will also
allow the agencies in attendance to express any further concerns with the EA W. From
this meeting, the developer may address the issues included in the listing, before the City
makes a formal record of decision.
Thank you all in advance for your attendance at this meeting, to assist Farmington in
promoting a quality development, which is environmentally sensitive.
Sincerely,

EA \V Requirements
1.
Indicate the correct amount of wetland and ditch acreage for the total site, 18.4 vs.
19.4 acres. (MDNR)
Wetland #19-352 is a DNR protected wetland and ditch-related work on the
Prairie Creek property should be carefully reviewed through an analysis of
hydrologic impacts to wetlands to ensure that Wetland #19-352 is not impacted,
and should also include any impacts to adjacent farmlands. (MDNR, BRAA,
EMP, SWCD, VR\VMO)
An evaluation of mitigation credit should be shown in the plan for proposed I: 1
conversion of wetlands and should be closely scrutinized by the WCA Technical
Evaluation Panel (TEP). (MDJ\R, BRAA, SWCD, VRWMO)
The EA W shows that the northeastern portion of the site contains designated
floodplain area as identified on the Federal Emergency Management Agency
(FEMA) floodplain maps for the City of Farmington and any existing and
proposed floodplain boundaries should be'shown. Cautious review of the
hydrology and hydraulic information concerning the floodplain boundaries should
be pursued. (MDNR, MC, BRA-\, SWCD, VRWMO)
The proposer should pursue a Letter of Map Revision (LOMR), or a Letter of
Map Amendment (LOMA), as deemed appropriate from FEMA. (MDNR, MC,
BRAA, EMP, VR\VI\10)
The proposer should clarify that the total runoff volume will increase due to the
land use conversion resulting in increased impervious surface. (MDNR)
Since the seasonal high water table depth is between 1 to 2.5 feet, the
reconstruction of the central drainage ditch on the site may not lower the seasonal
water table. (MC)
Further investigation into lowering the water table is required to determine
whether lower groundwater levels will impact the groundwater component of the
hydrology that maintains wetland #19-352. (MDNR)
The downstream water quantity effects upon the ditch extension into Empire
Township as well as North Creek have not been addressed. (EMP, SWCD)
Basin B would "most likely be converted to mowed bluegrass lawn" only if
surficial groundwater is lowered. (SWCD)
Basin C has been designated in Farmington's SWMP as a "Protect" wetland,
however, the EA W classifies it as a "RestorelUtilize" wetland, requiring further
investigation. (VR WMO)
Farmington's SWMP designates the drainage ditch as "Manage 1" wetlands and
as secondary greenway corridors and impacts to these wetlands as a result of
development are unclear and should be further investigated. (VRWMO)
The amount of wetland fill and excavation by type and basin will need to be
specified, as the impacts to individual wetlands are unclear. (VRWMO)

Ditch plans need to be reviewed to ensure that wetland # I9~ 352 is not impacted
by ditch-related work. ~MDNR)
Any structures or proposed trails should be placed far enough away from the
natural meandering of the stream. (MDNR)
By eliminating a few lots or reconfiguring the lots to make room for a storm water
basin, Basin B would not have to be filled for road construction and lot
development. (MDNR)
A bridge crossing the drainageway could create fewer impacts than the proposed
filling of the drainage way for a road crossing.
Storm water runoff should be pretreated prior to discharge into \vetlands by
utilizing ponding areas in close proximity to the drainage ditch/wetland system,
without constructing the ponds within existing wetlands. (BRAA)
Storm water pipes should be located on streets or on City property so that future
access and maintenance is practical, and should not be located in residential lots.
(BRAA)
Storm water should be discharged into catch basins rather than using rear yard
drainage swales and discharging runoff into flared-end culverts. (BRAA)
The City should continue coordination with Dakota County, Empire Township
and MNDOT to ensure that 1951h Street West and 20gth Street West provide future
connections to TH 3 as identified in the City's Thoroughfare Plan. (MNDOT)
Further design of the extent of grading into Empire Township should be
completed because the T o\\'llship requires any grading work that deepens the
ditch bottom by 6 inches is required to have a grading permit. (EMP, VRWMO)
Information concerning the effective best management practices selection, proper
installation and ongoing maintenance will be critical to protecting water quality
during and after construction in the proximity of North Creek and should be
reviewed carefully. (SWCD)
The District recommends the use of infiltration BMPs, on-site storage and
vegetated storm water conveyance channels to the extent practicable. The
NPDES permit requires the use of wet sedimentation basins - dry sediment basins
do not fulfill NPDES requirements. (SWCD)
The proposed residential development density should be clarified to ensure that
the development is low density residential as shown in the Farmington's SWMP.
(VRWMO)
Farmington proposes two small ponds near the ditch; however, the EA W does not
address these ponds. (VR WMO)

City Requirements
1.
The City could impose additional deed restrictions on future land owners in order
to protect the wetlands, along ",ith the installation of information-bearing signs
and the planting of shrubs on the wetland edge. (MDNR)
The City could impose deed restrictions or conservation easements in backyards
to ensure future residents do not encroach into wetlands in dry years. (MDNR)
The total amount of developed acreage from all development in this area must not
exceed the developable acreage approved by the Council in the MUSA
Expansion, regardless of rezoning or redetermination of the floodplain. (MC)
The City needs to deed the MCES an access easement for the meter station as part
of the approval process. (MC)
The wetland management classifications in the City have not yet been determined
and if a certain wetland needs to be classified prior to the completion of the
inventory, a request for wetland management classification should be sent to the
City. (BRAA, VRWMO)
Given the lack of a regulatory program at the WMO level, all significant
regulatory constraints will need to be enforced by the City of Farmington.
(VRWMO)
The project may involve some fill within the flood fringe. The City of
Farmington does not allow the filling of the flood fringe at any time. (MC, EMP,
VRWMO)

RE:
Prairie Creek East Schematic PUD
After further review of the Prairie Creek East Schematic PUD, it has become apparent to
City staff that there are a number of issues which could significantly impact the
schematic layout of the project. Therefore, City staff is recommending that the Prairie
Creek East Schematic PUD be continued to the April 14, 1998 Planning Commission
meeting in order to resolve the following issues:
1. Engineering issues concerning the storm sewer layout as explained in the
City Engineer's comments dated February 20, 1998. (See attached).
2. Determination of the correctness of the floodplain shown on the plan
compared to the City's Surface Water Management Plan.
3. EA W issues concerning the wetlands on the site. As stated at the February
24th Planning Commission meeting, comments by other agencies
reviewing the project must be delivered to the City by March 25. Early
indications by agencies who have contacted the City indicate that there
may be significant issues that will need resolution before the Prairie Creek
East EA W can be approved. (See attached Bonestroo and Dakota County
Soil and Water Conservation District comments).
Each one of the above issues could significantly impact the layout of the schematic plan
by requiring grades to be changed, lots to be reconfigured or removed entirely and/or the
possibility of significant impact findings in the EA W. Since these issues are so far
reaching in the overall design of the project, City staff recommends that additional time
be allowed to meet with the developer and other agencies reviewing the project for
adequate comments to be gathered by the staff. It is recommended that the schematic
plan be continued at a minimum to the April 14th Planning Commission meeting.

Comprehensive Plan:
Low Density Residential
Proposed Zoning Change:
R-l PUD
Surrounding Land Uses:
The site is bounded by single-family
development to the west and on the north,
east and south by undeveloped cropland,
wetland and woodland. The undeveloped
property on all sides is likely to develop
within the next several years.
Current Land Use:
Agriculture
Terrain:
Topography on the site is quite flat, with
elevations ranging from 920 in the northwest
part of the site, to about 904 in the ditch
bottom in the southeast part of the site. The
site drains southeast toward North Creek,
which in turn drains about one and a half
miles south to the Vermillion River.
Project Description:
The Prairie Creek East development is a
multi-phased single-family housing project
proposed for construction in northeastern
Farmington. The development includes
approximately 415 single-family residential
lots, 18.4 acres of wetland, 3.3 acres of
stormwater ponding, and 3.0 acres of
municipal parks and trails. Most of the site
is currently used for production of
agricultural rowcrops and vegetable crops.
An excavated drainage ditch flows southeast
through the site. The ditch flows from DNR
protected Lake Julia, located upstream of the
site, to North Creek, which is located about
1,000 feet east of the site. Drainage from
the site flows south and east about 2,300 feet
before reaching the confluence with North
Creek.
Additional Comments:
The schematic plan proposes 415 single family residential lots and which will be
constructed in seven phases. The street system shows two access points from the west
connecting with 187th Street and Eaglewood Trail in the Prairie Creek 4th Addition.
.
.
.
Two connections to the north are proposed along with one access to the south of the
property .
The plan proposes approximately seven ponding areas throughout the site along with a
drainage ditch running from the northeast corner of the property to the south-central
boundary of the property. A proposed recreational trail will run the length of the
drainage ditch.
The following information is required to be submitted to allow for a complete review of
the Schematic Plan:
1. Plan data must be shown stating number of lots, density, acreages, etc.
2. Road widths should be shown on the plan.
3. Additional information is required by the Engineering Department (see
comments).
4. Phasing of the project needs to be reviewed to ensure that no long dead end streets
will be constructed due to inadequate phasing of the project.
5. Comments by reviewing agencies need to be recievied in order to generate a
thorough review.
In addition to the above comments, an Environmental Assessment Worksheet (EA W)
was required for this property to comply with the Environmental Quality Board's
requirements concerning the number of lots proposed in a development. The EQB
specifies that an EA W is required when more than 250 single-family lots are proposed in
a project. The Prairie Creek East project proposes 415 single family lots.
In the EA W review process, the City of Farmington is the Responsible Governmental
Unit (RGU) for the project and is legally responsible for the accuracy and completeness
of the information contained in the EA W. The RGU has 30 days from the time the
proposer submits the EA W to determine ifthe EA W is accurate and complete. During
this time, the RGU may request additional information be provided, or that the proposer
make changes to the EA W. The RGU must establish that it has independently verified
information in the EA W to be accurate and complete. While the proposer provides
information for the EA W, the EA W is ultimately the RGU's document.
Once the 30 day period is completed, the RGU must respond to all comments and make a
decision of no significant impact or EIS need decision.
Bonestroo, Rosene, Anderlik & Associates is assisting the City in determining if all
information in the EA W is accurate and complete. The City received the EA W on
February 9, 1998. At this time, the City is eleven days into the review process for
insuring accuracy and completeness of the EA W. Therefore, City staff is recommending
that the schematic plan not be held up concerning the review of the EA W, but a thorough
review of the EA W must be completed before any preliminary plat is submitted to the
City.

Reauested Action:
City staff is recommending that the Prairie Creek East Schematic Plan be continued to the
March 10th Planning Commission meeting in order to receive additional information
required by the City in the schematic plan review process.
