CONSIDER APPROVAL OF RESOLUTION 99-XX
APPROVING THE CONDITIONAL USE PERMIT FOR
EXCAVATION OF SAND AND GRAVEL FOR RYAN
CONTRACTING ON PROPERTY LOCATED IN THE SOUTH
EAST QUARTER SECTION OF SECTION 22, T 115, R22,
LOCATED ON MCKENNA ROAD
Historv: On September 29, 1999, a completed application was
received for the excavation of sand and gravel from property located in
the SE Y-t, Section 22, Township 115, Range 22. This property is
owned by Richard McKenna and Joseph and Carolyn Kinney. Due to
an error in the legal description provided and upon recommendation of
staff, the Planning Commission opened the public hearing on October
25, 1999 and continued it to November 8, 1999. On November 8,
1999 the Planning Commission recommended the City Council
approve the CUP with conditions.
Ryan Contracting is proposing to operate a sand and gravel mining
operation. The operation will consist of mining and processing
including descreening, stockpiling, and sale of product. Aggregate
washing or operation of an asphalt plant is not a part of this operation.
Ryan intends to operate at the site for approximately 10 years and
remove 500,000 cubic yards of materials. The materials mined will be
used for road construction and general fill. The operation will run
from 6 a.m. -8 p.m. Monday through Friday and 8 a.m.-5p.m. on
Saturdays. Attached is a 5-page submittal from Ryan Contracting
specifying the details of the proposed operation.
Current Circumstances: The subject site consists of approximately
30 acres with 13 acres included in the mining plan. Section 1101.509
Grading, Filling, Land Reclamation, Excavation requires a Conditional
Use Permit for excavation of more than 400 cubic yards. An
Environmental Assessment Worksheet is not required by statute. The
City may, however, require one be completed. After meeting with

Ryan Contracting, and evaluating the materials submitted before and
after the November 8th Planning Commission public hearing, staff feels
the issues that would be raised with an EA W can be addressed with
our reVIew.
The Issues: The proposed Conditional Use Permit should be reviewed
in accordance with the criteria found in Section 1108 of the City Code
and Section 1101.509. Section 1101.509 is the provision on Grading,
Filling, Land Reclamation, and Excavation. The criteria are shown
below:
City Code 1101.509 (2) Excavation.
Excavation of material exceeding 400 cubic yards of sand, gravel, or
other material from the land shall be permitted only by CUP. The
permit application shall include, but is not limited to, a site plan which
shows the finished grade of the land after the excavation has been
completed, the effect of the proposed excavation upon the community
and the adjacent land, the type of material to be extracted from the
land, the type of equipment to be used, the period of time the
excavation operation will be conducted, plans for implementation of
measures to guarantee safety of the site and the excavation operation,
plans for rodent and other animal control, fire control, general
maintenance of the site and adjacent area, providing for control of
material hauled to or from the site, and controls to be employed to
limit the effect of wind or other elements on the site and the material
extracted from the site.
The permit application shall include a plan which shows the routes of
trucks moving to and from the site to remove material from the site, an
inventory of significant trees on the site, and other pertinent
information necessary to the decision whether to approve the CUP.
No permit shall be granted for a period longer than 12 months.
The CUP shall impose conditions upon the owner of the land to be
excavated and the person performing the excavation operation which
will prevent damage to the community and adjacent landowners
during the course of the excavation operation. Those conditions may
impose restrictions in all areas affecting the excavation operation and
the City may require a Letter of Credit to insure the conditions
imposed and the completion of the work will be performed in the
manner described in the plan and CUP.
The issues listed below are responses to the ordinance criteria and to
the information discussed at the November 8th Planning Commission
public hearing. The notebook dates November 19, 1999 provides the
complete Ryan application with all amendments made.
\ \fs I \sys\dept\planning\99fi1es\99cup\99-07 5\99-075 cc.docPage 2
1. Submit a landscape plan prepared by a registered landscape
architect, with one planting per 40 feet of site perimeter, as
required by City Ordinance.
City Ordinance requires I tree per 40 feet of site perimeter. 90 Trees
are required to be planted on the site. Credit is given for existing
materials. There are 94 existing trees on site meeting the size and
species of the Ordinance. Only one of these trees is to be removed as
part of the excavation operations. Since the remaining 93 trees will be
preserved, no additional plantings are required as a part of the
Landscape Ordinance.
2. Submit a tree inventory and a tree preservation plan indicating
the specific trees to be removed and replacement as required per
City Ordinance.
There are 1,540 total significant caliper inches on the site. 25% or 345
caliper inches can be removed without replacement. The applicant is
proposing to remove one 42-inch tree or 3% of the total caliper inches.
The Tree Preservation Plan meets the ordinance.
3. Submit expanded reclamation plan indicating how the area
will be graded and reclaimed so as to be suitable for future
residential use. A staging plan for reclaiming the site as it is
completed must be a part of this. The site should be restored with
top soil, seed and additional landscaping to control dust as soon as
possible after staging areas have been mined.
The applicants have provided letters from the property owners stating
their future intended use is agricultural. The property owners are
satisfied with the future reclamation as it relates to their future
proposed use. At this time, until utilities are available the proposed
future use of agricultural is reasonable. The Comprehensive Land Use
Plan designates this property as RL/MD (Low to medium density
residential). A future residential development will be possible on the
site as slopes will not exceed 3: 1.
4. Submit a site plan indicating proposed structures (including
temporary restroom facilities), and fixed equipment with setbacks
and proposed fueling areas. Any fueling areas and tanks should
be located on an impervious surface and meet structure setbacks.
Specifications for the parking area should be submitted and
compliant with City Code requirements (paved with curb) and
setbacks indicated. Parking area and equipment storage areas
should be screened. Fixed equipment and parking will not be
permitted over a lot line and must meet all required setbacks. A
\ \fs 1 \sys\dept\planning\99files\99cup\99-07 5\99-07 5cc.docPage 3
l' lr
contingency plan must be submitted and approved by the City
Engineer for properly handling all fuel spills related to fixed tanks
or equipment.
The screen plant is 150 feet from the nearest property line and the
parking area is 100 feet from the nearest property lines. This exceeds
the minimum required setbacks per ordinance. Specifications on the
fuel storage container have been provided. It is an enclosure which
prohibits leaking into the ground by design. The applicant will pave
and provide curbing of the parking area. All fixed equipment will
meet setbacks. The parking area needs to be screened. This is an
outstanding condition made a part of the resolution.
5. Submit a plan for continual monitoring of water quality. A
report shall be submitted prior to beginning mining, with reports
submitted to the city on a regular basis. A plan for maintaining
the current quality of water in the area must be submitted prior to
beginning work.
A letter from Ryan states annual testing of the wetland will be
submitted to the City. An attached letter from Braun Engineering lists
the chemicals to be monitored. This is acceptable and is made a
condition of the resolution.
6. The storm water calculations were prepared by an engineer
and the drainage plan was prepared by a land surveyor. The
grading plan should clearly indicate property lines and proposed
grades and berming. The grading plan should be revised as
follows: Additional silt fence is needed on the SW corner of the
site. Hydrologic/hydraulic calculations needed for 2,10 & 100 year
event storms showing existing and proposed run-off rates from the
site in cubic feet per second (CFS), pond slopes below normal
water level are to be 6:1 slope, 4:1 slopes required above the
normal water level of the sediment ponds, all other grades cannot
exceed 3:1.
A revised grading plan was submitted and is acceptable. However,
hydrologiclhydraulic calculations submitted are inadequate (Memo
11/19/99 from Sue McDermott). The proper information (direction
and rate of run-off) must be submitted prior to the recording of the
resolution and is a condition of approval.
7. DNR issues include protection of DNR wetland #70-247W.
Water use for dust control of greater than 10,000 gallons per day
or 1 million gallons per year requires a DNR permit. Provide a
schedule with quantities and specific water sources for dewatering.
\\fs 1 \sys\dept\planning\99files\99cup\99-07 5\99-07 5 cc.docPage 4
The operation of the pit cannot result in the drainage or other
degradation of the DNR protected wetland.
This is a condition ofthe resolution.
8. A letter of credit must be submitted. The LOC will be for
125% of landscaping costs, road maintenance/reconstruction, and
environmental testing/inspections to ensure compliance with the
CUP. Estimates or bids must be submitted for the required
landscaping. Estiinates for road maintenance and environmental
testing must also be submitted and approved by the City Engineer.
An estimate has been submitted and is acceptable. A LOC acceptable
to the City Attorney must be submitted prior to recording the
resolution. This is a condition listed on the resolution.
9. Submit plan for dust control. Water what, where, when?
The applicant has submitted a letter identifying dust control methods.
They will water the site within 24 hours of city notification if needed.
This is a condition in the resolution.
10. Submit plans for maintenance, upgrading, clean up, and safety
of McKenna Road/CSAH 42.
The applicant met with the engineering staff regarding this concern.
The applicant intends to maintain the current condition of McKenna
Road throughout the excavation. A LOC will be posted with the city
for maintenance and/or repair. The condition of McKenna road will be
reviewed on an annual basis as a part of renewal of the CUP. The
applicant is responsible for maintain the current condition of McKenna
Road.
11. The CUP is valid for one year. Renewal of the CUP is to
include a staging plan to date, reclamation to date, along with
water quality, road quality, wetland quality, and air quality
reports submitted by qualified professionals.
This is a condition listed in the resolution.
CONDITIONAL USE PERMIT (CUP) ANALYSIS:
Section 1108.200 of the City Code sets forth the criteria for approval
of a CUP:
\\fs 1 \sys\dept\planning\99files\99cup\99-07 5\99-07 5 cc.docPage 5
1 I lr
[
(1) The use is consistent with and supportive of the goals and
policies of the Comprehensive Plan.
Objective 5, under the goal of Security, is to Provide for conservation
and protection of the natural environment. The policies include
providing adequate regulation to prevent the development of endeavors
which will create a hazard to the environment and to require
developers to retain the natural environment as much as possible. The
conditions set forth in this CUP address environmental hazards and
require land reclamation and site restoration.
Another policy of the Comprehensive Plan is to require developers to
retain the natural environment as much as possible. Considering the
proposed mining operation, it is difficult to restore the site to a natural
condition. The Landscape ordinance allows for credit for existing
materials preserved and the project complies with the Tree
Preservation Plan with removal of less than 25% of the total caliper
inches. A condition of the CUP should require exact replacement of
trees removed (42 caliper inches) to restore the natural environment as
much as possible.
The Comprehensive Land Use guide plan, designates the future land
use as single family residential. The reclamation plan is acceptable to
the property owners for their current and future agricultural use.
(2) The use will not be detrimental to the health, safety,
morals and general welfare of the community as a whole.
Based on staff and Planning Commission review, the proposed use
will not be detrimental to the health, safety, morals and general welfare
of the community. Annual review of the CUP will ensure ongoing
protection ofthe community.
(3) The use is consistent with the intent and purpose of the
Zoning Ordinance and the Use District in which the Conditional
Use is located.
Section 1101.509 of the Zoning Ordinance allows Grading, Filling and
Land Reclamation as a Conditional Use within any zoning district.
The conditions set forth in the Zoning Ordinance will be met with the
issuance of the Conditional Use permit.
(4) The use will not have undue adverse impacts on
governmental facilities, services, or improvements which are either
existing or proposed.
\ \fs 1 \sys\dept\planning\99files\99cup\99-07 5\99-07 5cc.docPage 6
The use will not have adverse impacts on governmental facilities,
services or improvements as the applicant will be responsible for
maintaining the condition of McKenna Road and CR 42 as is exists
prior to the issuance of the CUP. In order to ensure this, it is necessary
to require a Letter Of Credit (LOC) for the maintenance of McKenna
Road. Costs related to the proposed use, such as expenses for
inspections and testing, will be borne by the applicant.
(5) The use will not have undue adverse impacts on the use
and enjoyment of properties in close proximity to the conditional
use.
The use will not have undue adverse impacts on the use and enjoyment
of properties in close proximity as the proposed mining operation is
located approximately 30 acres of which only 13 acres will be mined.
The property owners have signed the application, giving their consent
for the proposed use. The property to the north is agricultural in use
and the nearest residence is approximately 185 feet from the proposed
area to be disturbed (McKenna residence). The next closest dwelling
is approximately 325 feet from the area to be disturbed.
Staff does not anticipate development in the area to occur until utilities
are extended. Under the Comprehensive Plan, this could and will
occur at some point in the future. (Staff expects this to be at least 10
years.) However, development will be driven by property owners
desire to develop the area and would not necessarily be prohibited to
do so under the Comprehensive Plan or Zoning Ordinance.
The applicant will be responsible for inspections and testing to assure
maintained quality of roads, trees, and wetlands. Costs related to the
proposed use, such as expenses for inspections and testing, will be
borne by the applicant.
(6) The use is subject to the design and other requirements of
site and landscape plans prepared by or under the direction of a
professional landscape architect, or civil engineer registered in the
State of Minnesota, approved by the City Council and
incorporated as part of the conditions imposed on the use by the
City Council.
One tree per 40 feet of site perimeter is required. Credit is given for
existing materials. The existing 94 trees are sufficient to meet the 90
trees required on site. A complete tree preservation plan has been
submitted. 25% Of the total caliper inches can be removed without
replacement and the applicant is proposing to remove one tree (3% of
total inches). Compliance with these provisions exists.
\\fs 1 \sys\dept\planning\99fi1es\99cup\99-07 5\99-07 5cc.docPage 7
'IT lr
(7) The use is subject to drainage and utility plans prepared
by a professional civil engineer registered in the State of
Minnesota which illustrate locations of city water, city sewer, fire
hydrants, manholes, power, telephone and cable lines, natural gas
mains, and other service facilities. The plans shall be included as
part of the conditions set forth in the CUP approved by the City
Council.
The storm water calculations and drainage plan were prepared by a
professional engineer. No utilities are planned such as water, sewer,
electricity, gas, or telephone. Additional storm water information is
needed and has been made a condition of the resolution.
(8) The use is subject to such other additional conditions
which the City Council may find necessary to protect the general
welfare, public safety and neighborhood character. Such
additional conditions may be imposed in those situations where the
other dimensional standards, performance standards, conditions
or requirements in this Ordinance are insufficient to achieve the
objectives contained in subsection 1108.202. In these
circumstances, the City Council may impose restrictions and
conditions on the CUP which are more stringent than those set
forth in the Ordinance and which are consistent with the general
conditions above. The additional conditions shall be set forth in
the CUP approved by the City Council.
Additional conditions are being recommended based on the issues
addressed with specific review of City Code 1101.509 Grading,
Filling, Land Reclamation and Excavation, the DNR Handbook for
Reclaiming Mining Sites, staff review, and public comments received.
Conclusion: Planning Commission and staffhave concluded the
proposed excavation of sand and gravel is reasonable and not
detrimental to the community. The Planning Commission and staff
recommend approval of this request subject to the following
conditions:
These conditions must be met prior to the recording of the
resolution:
1. A one for one replacement of trees removed, (42 caliper inches) is
to be completed as part of the reclamation and staging plan.
Landscaping plan to indicate this additional replacement.
Plantings are to be installed upon completion of phases.
2. Landscaping of 1 tree per 10 lineal feet of berm is to be installed as
per item 7 on Recapitulation of CUP Application submitted by
Ryan Contracting. A complete landscape plan is to be submitted

B. Case File 99-075 Ryan Contracting is requesting a Conditional Use Permit
for grading, filling, land reclamation and excavation. The applicant is intending to
operate a sand and gravel mining operation.
Planner Jenni Tovar presented the Planning Report dated November 8, 1999, on file in
the office of the City Planner.
On September 29, 1999, a completed application was received for the excavation of sand
and gravel from property located in the SE 1,14, Section 22, Township 115, Range 22. This
property is owned by Richard McKenna and Joseph and Carolyn Kinney. Due to an error
in the legal description, upon recommendation staff, the Planning Commission opened
the public hearing on October 25, 1999 and continued it to November 8, 1999.
Ryan Contracting is proposing to operate a sand and gravel mining operation. The
operation will consist of mining and processing including de screening, stockpiling, and
sale of product. Aggregate washing or operation of an asphalt plant is not a part of this
operation. Ryan intends to operate at the site for approximately 10 years and remove
500,000 cubic yards of materials. The materials mined will be used for road construction
and general fill. The operation will run from 6 a.m. to 8 p.m. Monday through Friday and
8 a.m. to 5 p.m. on Saturdays.
Staff received necessary information on Wednesday but were unable to review before the
packets went out. The staffhas since reviewed the information and felt the outstanding
conditions and concerns were met. Staff recommended approval with the 5 conditions
listed in the Planning Report.
Tom Ryan, President of Ryan Contracting, explained the Conditional Use Permit request
was to use the natural aggregate resources in the property and through the process address
all environmental issues and concerns by staff.

Planning Commission Minutes
November 8, 1999
Comments from the public:
Craig Ahlman, 13799 McKenna Road, said he did not want this project next to his
property. His other concerns are the truck traffic and times of operation. It is a long and
big operation for the area.
Rick Palla, 13755 McKenna Road, said he and his neighbors fought a gravel pit 10 years
ago when the same family was trying put in an adjoining pit. Many residents fought the
proposal and won. In the end, the Dakota Community bought the land. Palla felt his
weekends off will be spent next to a mining pit. Tovar explained the surrounding
properties. Palla felt there was a lot of traffic in the area right now and was concerned for
truck traffic. He felt the hours proposed are unreasonable and stated no one wants to live
next to a gravel pit.
Tovar explained the City sent notices to residents within 350 feet ofthe project. The City
also sent out a review request to the Dakota Community prior to the report, There is a
letter in the Commissioner's packets from the Community with their concerns.
Tom Ryan, the applicant, commented they had a grading permit two years ago and
voluntarily stopped mining until the City could change their conditional use permit
process. Ryan said they want to be a positive force in the community. He went on to say
they might be done in 3 years, hopefully they would not be mining in the area for 10
years, but it is unknown. They felt 10 years was suitable. The renewal is on an annual
basis and if there are problems they can be brought up yearly. Concerning the hours of
operation, Ryan said it is very unlikely they would be working during non-construction
season. One of the conditions is no lighting. They cannot work in the dark and do not
like to work on Saturdays. They are just trying to leave some leeway to work
sufficiently.
Evonne Anderson, 13222 Pike Lake Trail, representing the Southdale YMCA questioned
the County Road 21 expansion and how it fits in the Watershed District. They are
concerned with the high water at Pike Lake. Anderson also questioned the truck traffic
on County Roads 16 and 42. They want to make sure there are safety precautions.
Rye responded the County Road 21 alignment will be 300 to 400 feet from the property.
McDermott pointed out a letter from the Watershed District indicating they would not
look at the permit until the City approves the project.
Tyler Enright of Ryan Contracting explained the proposed traffic flow stating County
Road 16 will not be used.
The public hearing was closed at 9:12 p.m.

Planning Commission Minutes
November 8. 1999
Cramer:
. Did not agree with staffs recommendation to approve.
. Shepherd of the Lake Church is proposing a campus at the comer of County Road 42
and Pike Lake Trail.
· That portion of County 42 and McKenna is cut down to 2 lanes and is notorious for
being a danger area.
. The Dakota Community indicated they had concerns with a nearby well.
. McDermott responded the issue is addressed in Ryan's proposal and is within the
guidelines issued by the Department of Health.
. Does not feel this development is appropriate for the location given the other types of
developments in the area. Will not support.
V onhof:
. Disagreed with Cramer. Felt this Conditional Use Permit is an interim use and is
consistent with the Comprehensive Plan. It comes back for renewal every year.
. The 11 issues in the Planning Report have been addressed. Any approval would have
to address the concerns as part of the plan.
. Regarding the off-site traffic and impact, Ryan agreed to maintain the road. It is also
part of the condition.
. Another concern is regarding noise on the site. The decibel level has been addressed
and is adequate.
. This is not a permanent long term use. It is appropriate and the conditions are met.
Stamson:
. Agreed with V onhof, it is a temporary use and expires within the time frame ofthe
2010 Plan. It is appropriate within the Comprehensive Plan.
. His concerns have been addressed by staff.
. One concern is the hours of operation. What are Savage's time for operation? Never
had a problem with neighboring Savage's pit. Tovar responded the hours of operation
are consistent with the City's combustion engine ordinance which allows
lawnmowers and other types of machinery allowed within the hours.
. Six p.m. deadline is more appropriate.
. Tom Ryan said the reason for the hours requested is because it is consistent with the
City's hours of operation. He also addressed V onhof s concern of decibels. Their
loudest decibel is in the 70 to 80 range.
. Ryan said it is not their intent to occupy the pit full-time.
V onhof:
. Be consistent with the time and noise ordinances.

Krier said he would like to address some of the Commissioner's concerns. The
Commissioners felt it was not appropriate to reconsider this issue because of staffs
concerns about review time and the fact that persons appearing for the public hearing
were not present.
5. Old Business:
6. New Business:
A. Case File 99~083 Chris Anderson is requesting a vacation of a portion of
frontage road located adjacent to 16020 Eagle Creek Avenue.
Planner Jenni Tovar presented the Planning Report dated November 3, 1999, on file in
the office ofthe City Planner.
The Planning Department received an application from Chris Anderson requesting the
vacation of the portion of public roadway located in front of his property. The purpose
of the vacation is to give Mr. Anderson more property in the front yard, resulting in a
private area for a future garage. While variances would be needed for a future garage, the
variance request would be minimized with greater lot area. Mr. Anderson is proposing to
vacate 26.50 feet of right-of-way with 13 feet being retained in a utility easement for the
City. The intent of the Comprehensive Plan will be met, however, there is a public
interest in retaining the entire right-of-way as platted. Planning staff recommended
denial of the request as submitted.
Comments from the public:
Chris Anderson, 16020 Eagle Creek Avenue, felt there was adequate distance to the road
for utilities. He would like to build a garage stating his neighbors would like to see him
complete it as soon as possible. Anderson would like to expedite the process. Neighbors
signed a petition in support.

SAND AND GRAVEL MINE OPERATION
PRIOR LAKE, MINNESOTA
1. INTRODUCTION
Ryan Contracting Company proposes to operate a sand and gravel mining operation within the City of Prior
Lake. Ryan Contracting Co. is seeking a Conditional Use Permit :from the City of Prior Lake to begin
mining and processing including descreening, stockpiling, and sale of product. Aggregate washing or
operation of an asphalt or.concrete plant is not 'a part of this operation. These activities, ifrequired, will be
performed off-site. The site is located on a combined 29.604 acres of land, of which onlv 12.91 acres are
included in the proposed mining plan. The following information briefly descdbes our proposed use, more
specific information can be obtained in our booklet submitted containing the Conditional Use Application.

3.) Names ofadiacent proPerty landowners includinj:!; all those within a 350 ft. radius of the property.
A property owner list was generated by Old Republic Title. This list is included as Exhibit 6.
4.) Specifications of the following. using apprOPriate maps, photographs and surveys:
a. The physical relationship of the proposed site to the community and existing
development.
The proposed site is located in the northeast portion of Prior Lake, just north of County
Road 42 on McKenna Road (See Exhibit 5).
Residential areas are located to the west and east of the site. The land to the north of the
site is open fields with some groves of trees. The land to the south is Mr. Richard
McKenna's house along with McKenna Road and field.
b. Site topography and natural features including location of water courses and water
bodies.
Exhibit 15 is a U.S.G.S. quadrant range map which illustrates the relationship of the site
tosUlTounding natural features. The site topography is shown in 2 foot contour intervals.
The plan also shows drainage ways and direction of surface water flow under current
conditions. The plan also shows the location and description of the trees in the area of
the proposed building site.
c. Description and quantity of material to be excavated.
Material to be mined from the site will consist of sand and gravel. The soils within the
mining limits are predominately Esthervi11e and Kingsley soils, both sandy loams
forming in loamy glacial outwash over sand and gravel deposits. The Scott County
Geological Atlas maps the site as a primary sand and gravel resource with over 35%
gravel.
Approximately 500,000 C.Y. of material will be mined from this site. The type of
material to be mined will be sand and gravel. lnitially a phase will be opened up by
stripping topsoil over a designated area This topsoil will be stockpiled on site and later
used in restoration. No topsoil will be sold or removed from the site. Any overburden,
fine clays, and silty soils which cannot be sold or utilized by the operator will also be
stripped exposing the underlying aggregate. Mining will create an active mine face with
a slope liot exceeding 1: 1. Perimeter slopes may be mined to 1: 1 and then. backfilled to
the grades shown on the mining plan. Final grades- over the base of the pit are at a
minimmn elevation of 870.00. Mining may occur below the depth of the grades shown
on the plan in areas where good material is encountered. All material replaced below
elevation of 870.00 will be structural suitable for building and will include certification
of any filling. These areas would then be backfilled as part of restoration for that
2
'T ,
particular phase. The maximum depth of mining will not exceed elevation 850.00. The
average restoration grade will be arOlmd elevation 870.00.
5.) The purpose of the operation:
The purpose of the mining operation is to obtain natural aggregate for use in the construction
industry. The operator will use material obtained from site to produce aggregates for road
construction and general fill.
6.) The estimated time reQuired to complete the operation:
The site will be active for an estimated 10-year period. The life of the site will be dependent on
market demand. The site will be operated in phases. Mining will begin in the western portion of
the site and progress to the east. Each year an annual report will be submitted, which will outline
areas to be stripped, mined, and reclaimed during the next mining season. TIlls will keep the City
up to date on the mining progress, and rate of mining activity at the site.
7.) The plan of operation:
Duration of MininJ! Activity: Mining activity typically occurs from March-December. The life
of the mine is estimated to be 10 years.
Hours of Operation: The site will be operated from 6:30 A.M. - 7:30 P.M. Monday - Friday and
8 A.M.- 5 P.M. Saturdays on a seasonal basis.
Overations: Operations will be initiated by stripping an area corresponding to the first years
excavation activities. The stripping will be shaped into berms along the designated setback areas.
These berms will be seeded to provide screening, noise and dust abatement. Material will be
excavated from .the working face, desanded, and stockpiled according to the various grades of
material. The initial location of the screening plant is shown on Exhibit 8. Mining will progress
in a west to east direction. Conveyors may be used to feed material to the screening plant
throughout the mining season. Each year, additional area will be stripped as the working face
moves easterly.
The screening plant is a portable plant and may be moved off of the site depending on the amount
and location of future contracts. Exhibit 8 shows the location of the screening plant.
Noise: All equipment will be operated within the noise emission standards established by the
Minnesota Pollution Control Agency (MPCA). Processing and loading activities are performed in
the lower elevations of the pit where the side slopes, vegetation and trees will act as noise barriers.
Ryan Contracting will operate in accordance with the noise standards established by the
Minnesota Pollution Control Agency for reSidential areas.
In addition, Ryan Contracting will be constructing a '"buffer" berm on the west edge to reduce
sound levels. Mining operations will begin at an elevation of 884.00 and continue down to a final
elevation of 870.00. The west berm will be constructed to an elevation of 910.00, initially
allowing for a 26 foot high berm to reduce noise. This berm will also be landscaped. Ryan
Contracting will install 2 inch trees staggered at an even ten feet apart on the berm. These trees
will be maintained and guaranteed. The berm will have topsoil placed on it. The topsoil will be
seeded, mulched, fertilized, and disc anchored to provide positive turf establishment.
The Minnesota Department of Natural Resources report. Industrial Minerals in Minnesota dated
September 1979 states, .. Typical mining equipment gen~ates noise levels as high as 88 decibels
(dBA) measured at 50 feet away from the source. Screeners can generate up to 78 dBA measured
3
from 50 feet from the source. Table 1 describes decibels (dBA) by comparison to familiar
environments. The Minnesota Pollution Control Agency has established noise standards which
include noise from mining activities. The MPCA states that, "acceptable sound levels for the
receiver are a function of the intended activity in that land area." Further, these standards
described the limiting levels of sound established on the basis of present knowledge for the
preservation of public health and welfare. These standards are consistent with speech, sleep,
annoyance, and hearing. The allowable noise level standards range from 50 dBA to 80 dBA.

Exhibit 8 shows the initial location of the screening plant, stockpiles, and haul roads which will
eliminate the need for trucks to back up sounding their back - up alarms. If requested, Ryan
Contracting will be willing to disconnect our backup alarms, if absolutely necessary. The
screening plant will be placed at various locations throughout the pit to minimize noise to the
surrounding area. Material will be stockpiled from the screening plant by conveyors.
Eauivment: Machinery will be kept in good repair. Abandoned machinery, inoperable
equipment and rubbish shall be removed from the site regularly. All buildings or equipment not
used for a period of one year shall be removed from the site. All equipment and structures shall be
dismantled and removed within 90 days after termination of the permit.
Natural Screenimz: The perimeter of the site shall be screened as shown on the aerial photo
(Exhibit 18). The aerial is from Scott County Surveyors and dated 1990. The severe
thunderstorms from 1998 destroyed the trees on the east side of the pit in phases n and ill, those
are shown in the aerial. The site will be screened from the residences to the north and west by the
groves of trees. This buffer area will provide both visual screening, and noise and dust abatement.
There are no residents to the east of the site.
Water: No well will be drilled on the site or washing of aggregates; however Ryan Contracting
will use the water from the ponds on site for dust control.
Fuel Storage: Ryan Contracting will be storing fuel on the site in an above ground 1000
gallon steel tank placed in a concrete enclosure. The fuel will be diesel fuel for the operating of
the screening plant and the construction equipment only. The concrete enclosure will contain
spills ifleakage did occur. The concrete enclosure is made by Crest and is a MPCA approved
design for this exact situation. Please see the Exln"bit 24 containing specifications on
the enclosUre. The enclosure-will have a roof over it along with a metal chain link fence. The fuel
tank will be locked when not in use. Due to the concerns from the Shakopee Mdewakanton Sioux
Community (SMSC) regarding fuel spillage, this is the best solution. The enclosure will trap fuel
that is spilled or leaked from the tank and will prevent fuel from contaminating the groundwater.
With the tank on site, this will reduce the number of refueling trips to 1he site thus decreasing the
possibility of a fuel spill. 10 the unlikely event a fuel spill would occur, Ryan Contracting would
4
.1----'------
respond by following state guidelines as outlined by the MPCA These guidelines are included
under Exhibit 24.
The MPCA does not require a permit for an above ground fuel tank less than 1,100 gallons.
Site Security: The gates to the site will locked when not in use. The rest of the site will be
protected by the current homeowner. Currently, there is a barbwire fence and snowfence securing
the site.
Par/dn';f: The parking area as shown on the Exh.ibit 8 is for employee parking only. The surface
of the parking lot will be of a gravel material like class 5. The gravel surface will be maintained
by Ryan Contracting on as need basis. The size of the parking lot will be large enough to handle
five full size vehicles. The parking of the construction equipment will be next to the screen plant
or near the center of the gravel pit.
8) Traffic& Travel routes
The site is located roughly ~milenorth of County Road 42. To access the site from County Road
42, trucks will exit off County Road 42, onto McKenna Avenue, and turn onto Richard
McKenna's property which is where the pit is located. Traffic from the site is reversed to C01mty
Road 42. Dust control methods will be implemented as indicated in Exhibit # 21. Ryan
Contracting proposes to limit the number of trucks visible to the public on this property to 6 at any
one time. Other trucks may be waiting within the pit, recessed and out of view of the public. At no
time will trucks be allowed to use McKenna Road to the north for an access to this property.
Please refer to Exhibit 14 for an example of signage.
9.) Drainage. Water Erosion Control. Sedimentation and Dust Control
Currently the site drains to the northwest over land and off site. Mining will move from the west
to the east with the pit floor sloping to the west maintaining this overall drainage pattern
. throughout the life of the site.
Erosion will be controlled be placing heavy-duty silt fence in the drain swale where the
sedimentation ponds will be constructed adjacent to the mining operation and by on-going
restoration of disturbed areas including topsoil placement and establishment of vegetation.
Sedimentation ponds will be constructed in the northwest portion of the site to treat runoff prior to
leaving the site. These ponds will be constructed at the beginning of operation. They are designed
to accommodate a 10 year; 24 hour stom runoff over the maximum disturbed area at any given
time. Exhibit 10 contains sizing computations done by Cal Hedlund with Gorman Land
Surveying, Inc. The location of the sedimentation ponds is shown on the proposed grading plan
(Exhibit 10).
Dust generated from vehicle traffic will be minimized by utilizing the existing access to the site.
A water truck will be used as needed to water used roads. On site processing equipment will be
recessed thereby minimizing the amount of dust leaving the site. The vegetated buffer area will
also reduce fugitive dust.
_ Stripping operations will be conducted in as short of a time frame as possible. The overburden
will be removed and stockpiled. The stockpiles will be seeded to reduce the source of dust. The
. site entrance roads will be watered as needed. Restoration of the site will be on going to minimize
the amount of area without vegetation at any given time. Fugitive dust, dust not associated with
specific processing activities, is also addressed in the sites Air Quality Permit which will be
obtained from the MPCA.
- 5
Calcium chloride is used statewide by the State of Minnesota, counties, cities, townships, and
recommended by consulting engineering firms throughout the state. The use of calcium chloride
on the gravel traffic routes will minimize the amount of dirt blown in the air. The screening plant
will be on the floor of the proposed pit. The vegetated berms, walls and trees will act as shields
J11inimizing fugitive dust. The existing trees on the west and south sides will act as a natural
buffer. On the north and east of the proposed pit, the existing fields will also act as natmal shields.
The proposed berms, trees, and fields will reduce the presence of pit operations from the view of
the public and residents.
Ryan Contracting Company will protect the site and adjoining sUITOl.mding properties from
erosion and sedimentation. If erosion occurs off site as a result of our operation, Ryan Contracting
will immediately clean up the debris at our expense and restore all damage to the surrounding
properties.
10) Tree Preservation:
A tree inventory has been performed on this site. There will be a total of three trees removed on
this site as a resuh of our proposed use. This equates to 3.03% of the total trees to be removed.
There vill be a total of 70" of trees removed out of a total of 2310" of trees sW"Veyed by Gorman
Land Surveying. The tree removal does not exceed the 25% tree removal limit, however Ryan
Contracting will be planting over fifteen trees on the west berm ih addition to the ten proposed
plantings shown in the attached plan. The tree plantings on the west berm will be done once the
berm is fully constructed. The remaining trees shown in Exhibit # 13 will be planted at the
completion of our project. The trees on the west berm will be planted within 4S days of April 15,
2000, p"oviding our CUP has been received by this date. Ryan Contracting will be planting the
trees in good faith to the City of Prior Lake and the adjacent residents. The proposed trees will be
maintained and guaranteed. The existing trees will be protected by means of snowfence with metal
posts and will be erected past the drip line of significant trees along the mining limits. Snowfence
will be maintained in place until restoration along the perimeter of the mining limits has been
completed.
11.) Rehabilitation Plan:
Rehabilitation of the mining area will be performed to restore the site to a stable condition,
minimizing the potential for erosion, and also allowing for future development of the land.
Rehabilitation will involve final grading, slope stabilization, application of topsoil and seeding and
mulching. Existing grades prior to mining are shown on the Existing Conditions Plan (Exhibit 7).
Exb.1bit 8 indicates the sequence and timetable of mining and the location of topsoil and
overburden storage areas. Restoration grades are shown on the proposed grading plan (Exhibit 9).
Existing perimeter side slopes will be mined to a maximum of 1: I and backfilled to a minimum of
2.5:1. The slope of the floor of the pit will be 1.00010. A minimum of 4" of topsoil will be placed
over the graded slopes and floor of the mining area. Vegetation will be established. Vegetation
will consist of MoDot Seed mix number 50A, a mixture of predominately Bluegrass, Bluestem,
and Bromegrass.
Sufficient topsoil is available on site for use in reclamation. Approximately 5 acres of the site will
be left with 2.5:1 slopes. This.area will require an average 4" depth of topsoil. Approximately 8
acres of the pit floor area will require an average of 4"'oftopsoil.
Restoration will be ongoing. Each year mined areas not utilized for processing or stockpiling will
be graded to the proposed plan. Topsoil will be applied and vegetation established to minimize
the amount of open area at any given time. An annual operating plan will be submitted each y~.
6
."_.,~'_."._~----_..~----.-_.
This plan will include a map which shows areas which have been reclaimed during the past
mining season. Areas to be reclaimed the following mining season will be noted as well.
Reclamation of the site: The site was originally and still zoned agricultural. The site is currently
outside of the Metropolitan Urban Service Area (MUSA). Mr. Richard McKenna and Mr. Joseph
Kinney are currently the two property owners of this site. Ryan Contracting bas a contract with
these owners for the removal of this material as shown in Exhibit 10. When the pit use has been
completed, Ryan Contracting will restore the land back to agricultural use. The site will have 4"
of topsoil and seeding over all disturbed areas. The site will not create a pond as other pits have
become. The only water in the pit will be in the sedimentation ponds that will be cleaned out as
part of the restoration of the site. After completion and restoration of the gravel pit, the use will be
at the discretion of the landowners. The landowners have indicated they wish to return the
property to agricultural use. Ryan Contracting will finnish the City with a $ 50,000.00 restoration
bond to guarantee restoration of this property.
12.) Permits:
In addition to the Conditional Use Permit and the annual permit renewal required by the City of
Prior Lake, Ryan Contracting may also be required to obtain the following permits:
. Minnesota Pollution Control Agency:
National Pollutant Discharge Elimination System (NPDES) General Storm water Permn:.
Ryan Contracting will be responsible for obtaining all necessary permits as required by the
MPCA. Copies of required permits will be submitted to the City prior to beginning mining
operations.
. DNR:
Department of Natural Resources will be informed, Ryan Contracting will be responsible for
obtaining all necessary permits as required by the DNR Copies of required permits will be
given to the city prior to beginning mining operations.
13) Maintenance of McKenna Road
Ryan Contracting Company will repair and maintain McKenna Road from County Road 42 to the
entrance of the gravel pit as needed at the discretion of Ryan Contracting and the City of Prior
Lake. A biannual review will be set up with the City of Prior Lake to observe the conditions of
McKenna Road and determine the need for repair. The condition of McKenna Road will be kept
in as good as condition or better while the gravel pit is in operation. Ryan Contracting Company
will post a $ 50,000.00 maintenance bond with the City of Prior Lake to guarantee maintenance
and repair of McKenna Road while our Conditional Use Permit is active. It is our understanding
McKenna Road may be realigned within the next five years. The extent of repairs to this road will
be negotiated with the City of Prior Lake to an acceptable level as agreed on.
14). Compliance:
The site will be operated as indicated in this permit application. Any additional conditions as set
forth in the permit will be adhered to. Once the operation has been established, any questions,
complaints, or requests by the city or residents should be directed to either Tom Ryan or Tyler
Enright of Ryan Contracting Company at .(612) 894-3200. Action will be taken immediately
where appropriate. Ryan Contracting Company will work in good faith to resolve any. complaints
or issues related to the .operation of the mine.
An annual report will be submitted to the city in conjunction with the annual permit renewal. The
report will show limits of current mining and processing areas, stockpile areas, the next phase of
stripping/mining, previous years restoration areas, the next years planned restoration activities, and
the qWlIltity of material removed from the site during the previous mining season .

15) Site Appearance
Ryan Contracting Company will be operating this pit in a professional manner. The pit will start
on the west side and work to the east. The pit will be have a full exposed face from the existing
ground to the proposed pit floor. The berms and slopes on the proposed pit will be constructed as
the pit takes shape, along with the restoration. (See Exhibit 9) The pit will be constructed in three
phases over a life span of roughly ten years. Each phase will not be constructed in three and a half
years, but will be constructed on need and/or supply and demand on the material available in the
pit. The phasing plan is outlined on how the pit will be constructed. (Exhibit 19 )
All equipment will be in operating use on the site. There will be no abandoned equipment on the
site that is the property of Ryan Contracting Company. This pit is to operate in a clean and neat
fashion, not to offend any of the residents in the area, property owners, or government officials.
Ryan Contracting will be the sole operator of this pit. There will be no other operators using this
pit if granted the conditional use permit. Once the CUP has been received Ryan Contracting will
be responsible for all activities in the pit and maintenance or repair of haul routes.
16) WETLAND # 70-247W
Please refer to Exhibit 22 showing the approximate location of the wetland in relation to the pit
location. This wetland will not be disturbed in anyway by our activities. The drainage on this
property runs from the southeast to the northwest. The location of this wetland is directly
southeast from our proposed gravel pit. There will be no drainage into the wetland, nor will the
wetland be drained of water. Currently, there is a natural buffer between this wetland and our pit
location. Ryan Contracting will review this area witb the DNR, and if requested, Ryan Contracting
will install heavy duty silt fence as a precaution. Currently, there is a natural land and wooded
buffer between our property and the wetland. This area will not be disturbed , nor traversed in
anyway.
17) Groundwater
Well Head:
Sanitation:
The concern by the SMSC in the elevation of the floor of the proposed pit to
their Public Water Supply (PWS) well is being taken with great concern. The
elevation of the floor in the proposed pit will start at an elevation of 884.00 and
may be excavated to an elevation of 850.00 with a restored elevation of 870.00.
The ground water is at an elevation of 743.00 according to the Mean Sea Level
(MSL.) with bedrock at 750.00 according to SC-Geo Atlas. Excavation of
mined material will leave over 100 feet between the proposed pit floor and the
Jordan Aquifer. The Minnesota Department of Health recommends at least 50
feet or more in separation. The distance between the aquifer and the pit floor is
double the recommended separation distance. This distance should satisfy
concerns the SMSC had with the proximity and operation of the proposed pit.
Ryan Contracting is proposing to use satellite toilet facilities on the site. A
maximmn of five employees will be working on the site, not including
.independent trucking companies. The satellite toilet facilities will.. be maintained
by an independent company and maintained weekly during the operating months
oftbe year. This facility will be located adjacent to our parking area as shown in
Exhibit 8. This facility will be removed when our operation is not in use.

Fuel Storaf!e: Ryan Contracting will be storing fuel on the site in an above ground 1000 gallon
steel tank placed in a concrete enclosure. The fuel will be diesel fuel for the
operating of the screening plant and the construction equipment only. The
concrete enclosure will contain spills if leakage from the tank did occur. The
enclosure is made by Crest and is a MPCA approved design for this exact
situation. Please see Exhibit 24 containing specifications on the enclosure. The
enclosure will have a roof over it along with a metal chain link fence. The fuel
tank will be locked when not in use.
Due to the concerns from the Shakopee Mdewakanton Sioux Community
(SMSC) regarding fuel spillage, this is the best solution. The enclosure will trap
. any fuel that is spilled or leaked out of the tank and will prevent fuel from
contaminating the groundwater. With the tank on site, this will reduce the
mnnber of refueling trips to the site and decreasing the possibility of a fuel spill.
In the unlikely event a fuel spill would occur, Ryan Contracting would respond
by following state guidelines as outlined by the MPCA. These guidelines are
included in our application Wlder Exhibit 24.
EQuioment Fuel: The SMSC has expressed concerns regarding possible fuel spills from the
intregal fuel tanks on our equipment. These concerns are unwarranted. The
intregal tanks constructed on heavy equipment are built for heavy operations to
withstand hard and severe use. The possibility of a fuel spill caused by a
ruptured fuel tank from our equipment is far less likely than a fuel spill from
your own car.
Ryan Contracting Company will not be drilling or installing any wells on this property.
Ryan Contracting Company will be taking water from the sedimentation pond for use on
site to water roads.
