PROPOSAL/SUMMARY
The applicant is proposing to create 75 single family lots on
property zoned RSF and located at the northwest corner of Lake
Riley and Lyman Boulevard. The parcel contains a large Class A
' wetland and part of the Hwy. 212 right-of-way. The applicant is
applying for preliminary plat approval and a wetland alteration
permit to allow development within 200 feet of a Class A wetland. .
' The applicant is proposing to subdivide 78 acres into 75 single
family lots. The 78 acres contains 34 acres which will contain the
75 single family lots, 23 acres of outlots and 20 acres of street
' right-of-way. The outlots are as follows:
Outlot A 23 ,339 square feet and is a remnant piece with
a large - drainage ditch going through it
located between what is shown as South Road
and Lyman Boulevard.
Outlot B 21,254 square feet and will be used as a
drainageway directing drainage into the Class
A wetland and is located at the end and north
of the South Road cul-de-sac.
Outlot C 410,659 square feet and contains the Class A
' wetland located at the southeastern section of
the property.
Outlot D 564,249 square feet and contains the Hwy. 212
' right-of-way and remaining property to the
north of Hwy. 212.
' The street right-of-ways proposed for the plat contain the internal
streets as part of the subdivision, proposed Hwy. 212, Lake Riley
Boulevard and Lyman Boulevard. The single family lots are divided
into 5 blocks. The net density of the proposed subdivision is 2.2
units per acre which meets the maximum of 3.4 units per acre for
residential low density. The lot sizes range from 15, 000 square
feet to 38,976 square feet with an average lot size of 19,969
square feet.
The subdivision has gone through several revisions to meet the
Zoning Ordinance requirements and to accommodate the Class A
wetland. With the exception of 3 lots, all of the lots meet the
Zoning Ordinance requirements and there will be no detrimental
impact to the Class A wetland which will be preserved in it's
natural state.

As part of the preliminary plat, the Park and Recreation Commission
is recommending dedication of Lots 21-26, Block 3, for park land
and staff is recommending additional right-of-way along the North
Road, West Road, Lake Riley and Lyman Boulevard. As a result of
the additional right-of-way along Lake Riley and Lyman Boulevard,
most likely the 3 lots between South Road and Lyman Boulevard will
be lost and Lot 1, Block 5 will become unbuildable with less than
50 feet of lot depth.
The Subdivision Ordinance requires a 300 foot offset for any local ,
street from the intersection. To meet the requirements of the
Subdivision Ordinance, the South Road would have to be shifted
approximately 60 feet to the north to maintain the 300 foot offset.
With the addition of right-of-way on Lyman Boulevard and shifting
South Road to the north to meet the Subdivision Ordinance, there is
a possibility that the applicant would also be losing lots north of
South Road and that any remaining lots in that area would have the
building pads shifted closer to the wetland and the 75 foot
setback. Due to the potential of the 300 foot offset requirement
pushing development closer to the wetland, staff is in favor of
granting a variance to the ordinance requirement and feels that the
240 feet that is being provided will still provide enough safe
access for vehicles entering and leaving the site. 1
The preliminary plat has several conditions of approval, with the
majority of the conditions are the basic conditions that apply to
all plats and will not result in significant change to the
preliminary plat. Therefore, staff is recommending approval of the
preliminary plat and wetland alteration permit with conditions
provided by staff. '
STREETS
The subdivision is being provided with internal streets for an
east/west future connection and access from Lyman Boulevard. The
subdivision also proposes 3 cul-de-sacs to access lots adjacent to
the Class A wetland. All of the streets provide the required 50
feet of right-of-way. Staff is recommending that the right-of-way
for the North Road and the West Road be increased to 60 feet as
they are anticipated to function as collector streets in the
future. This width will also facilitate the installation of a
sidewalk. The preliminary plat should note the right-of-way
dimensions of all streets. The right-of-way for the cul-de-sacs
are a 50 foot radius and the ordinance requires a 60 foot radius
for an urban cul-de-sac. The preliminary plat should be changed to
reflect this.
In comparing the proposed plat submitted with the County half-
sections, staff is unable to determine whether a 33 foot wide
1
I Lake Riley Hills
John Klingelhutz
October 3, 1990
Page 4
segment of land along the north half of Lyman Boulevard has been
previously acquired as right-of-way or acquired by easement.
' Nevertheless, preliminary results contained in the Eastern Carver
county Transportation Study (excerpts attached) point to traffic
volumes in excess of 7,400 ADT for this roadway. It's
characteristics rank it as a minor arterial, Class II which will
require a 120 foot right-of-way (60 feet on each side of the
centerline) . It is therefore necessary that a 60 foot wide right-
of-way be granted along the southern border of the proposed plat.
This width would also allow incorporation of the future trail along
Lyman Boulevard.
' The aforementioned transportation study designated the segment of
Lake Riley Boulevard north of Lyman Boulevard also as a minor
arterial, Class II roadway. Therefore, a 120 foot wide right-of-
way will also be required for this road segment. This width would
incorporate the future trail. Thus a separate trail easement would
not be necessary.
' The street widths provided in the preliminary is shown to be a 32
foot face curb to face curb. This is equivalent to the city
standard of a 35 foot back up curb to back up curb for an urban
' collector street. This standard is applicable to the North Road
and West Road. The applicant should be advised that the Loop Road,
South Road and South Cul-de-sac may be reduced in width to a 31
' foot back up curb to back up curb if so desired. The intersection
of South Road and West Road is located approximately 240 feet north
of Lyman Boulevard.
' The ordinance requires that a minimum centerline offset distance of
intersections be 300 feet. Therefore, the applicant will have to
shift the intersection of South Road and West Road approximately 60
' feet or receive a variance. The location of the South Road
provides lots with adequate area for development without impacting
the wetland. As previously stated, the city will be requiring an
' additional 27 feet along Lyman Boulevard to accommodate necessary
road improvements. As a result, the applicant will probably loose
3 lots between Lyman Boulevard and South Road. Most likely
shifting South Road further to the north, in addition 'to providing
' additional right-of-way will result in the loss of more lots and
pushing other lots closer to the wetland. Since it will result in
a more closer impact to the wetland due to the proximity of the
' homes and the street has an offset of 240 feet, staff would be in
favor of a variance and allow South Road an offset of at least 240
feet. The City Engineering Department has agreed to support this
' alternative.
Initially, the only access to the site will be from Lyman
Boulevard. When future development occurs around this site, it is
I
Lake Riley Hills
John Klingelhutz

Page 5
anticipated that North Road will be extended both to the east and
west and provide additional access points to the subdivision.
Until the North Road is extended in the future, temporary cul-de-
sacs
will be required to be installed at the ends of the North
Road. Barricades will also be required to be installed at the
temporary cul-de-sacs and they will be signed designating them to •
be only temporary and a future road extension. Outlot D, which is
being separated from the rest of the property by the improvements
for Hwy. 212, is currently designated as unbuildable and will be
platted in the future. At that time street connections to the site
will be reviewed.
There currently exists a private driveway along the easterly
boundary of the proposed plat which services a house located in the
northeast corner of the site. The residence driveway was
constructed via a dike which bisects the wetland area. It is
anticipated that the proposed Trunk Highway 212 improvement will
require the removal of this house. In order to convert the wetland
area back to it's original state as one whole wetland, staff is
recommending that the gravel driveway be removed. Such efforts
should be coordinated between the Department of Natural Resources,
Corps of Engineers and Fish and Wildlife Service and with the City
of Chanhassen. In preliminary discussions with DNR and Fish and
Wildlife, it was stated that it would be preferred to have the
original wetland re-established as one complete wetland. The plat
is proposing to continue to service the house with the existing
driveway through what is now being proposed as Lot 14, Block 2.
A driveway easement shall have to be provided over Lot 14, Block 2
for access to the existing house. Since the driveway will be
crossing over the end of North Road, the removal of the current
dirt road through the wetland will not remove access to the house
since access can now be obtained from the new North Road as part of
the subdivision.
UTILITIES
A study has been authorized by the City Council, at the request of
the applicant, to determine the feasibility of servicing this area
with a watermain and sanitary sewer. A condition of this
authorization was for the applicant to submit a $10,000 letter of
credit or cash escrow to guarantee payment of expenses associated
with the feasibility study. The security required has not yet been
received and as a result, the study has not been initiated. The
applicant does not want to submit a letter of credit or cash escrow
until the application has gone through the Planning Commission in
case it is recommended for denial or results in such extensive
changes that the project is no longer feasible. Once it is clear
that the project will move ahead, the applicant will submit the
letter of credit for the feasibility study to be initiated and
I
11

Lake Riley Hills
John Klingelhutz

Page 6
' understands that there will be no final plat approval until such a
feasibility study is completed and it is determined how the
' watermain and sanitary sewer will be extended to the site.
Staff is recommending that the applicant's engineer submit the flow
' calculations for the sanitary sewer system to verify pipe capacity
and minimum score velocities through all of the sewer segments
within the proposed subdivision. Staff is also recommending that
• the applicant's engineer verify that the existing lift station and
4" forcemain sewer to facilitate this subdivision is adequate in
size and capacity. It should be noted that the entire development
is proposed to be serviced by gravity sewer, however, the
connection point for this system will be in the vicinity of Lyman
Boulevard and Lake Riley Road and immediately upstream from an
existing lift station and 4" forcemain.
' EASEMENTS
All of the sanitary sewer and storm sewer extensions, will require
the respective drainage and utility easements and shall be denoted
as such on the plat. The proposed detention ponds and
corresponding access ways will require easements. The temporary
cul-de-sac at both ends of North Road will also require temporary
' easements to cover the portions outside of the platted right-of-way
and shall exist until such time that the road extensions are
constructed and the cul-de-sacs are removed.
GRADING
' The plan is proposing to grade the southern two thirds of the site.
The final grading will be similar to the existing topography on the
site which drains primarily southeast into the wetland area. The
steepest slopes will be found in the rear yard areas of the lots
surrounding the wetland area, specifically, Lots 30-35, Block 3,
and Lots 4-8, Block 3. Special slope stabilization methods such as
wood fiber blankets and Type III erosion control will be required
' in these areas.
The applicant was requested to obtain and provide information from
MnDOT detailing the current plan elevations for the corresponding
segment of future roadway for the Hwy. 212 improvement. This
information has not been submitted, however, some slope grading is
Ishown on the plan. Staff stresses the need for the applicant to
• submit the requested information on the future Trunk Highway 212
Project to verify the compatibility related to grades and
elevations of these two projects. Staff recommends that the
' applicant also provide some sort of noise abatement measures such
as earth berming immediately south of proposed T.H. 212 alignment.
Staff has received a letter from MnDOT stating that the
Lake Riley Hills
John Klingelhutz
October 3, 1990
Page 7
improvements of Hwy. 212 and the subsequent proposal for a single
family lot subdivision adjacent to it will require some form of
noise abatement. MnDOT further stated that such improvements would
not be paid for by MnDOT and are the responsibility of the
applicant and/or City.
DRAINAGE '
The majority of the site drains southeast into the wetland area.
Detention ponds are proposed to be constructed in an effort to
maintain the pre-developed runoff rate for the site. Staff is
requesting that the applicant's engineer review the total capacity
of these ponding basins needed to meet the predicted retaining
requirements. Also, the configuration and location of the pond are
such that access to the pond by the city for maintenance appears to
be very difficult, if not impossible at all. Staff is recommending
that the applicant provide a plan showing designated access points
to these ponding basin areas and verifying that they will be able
to be serviced by the city crews when necessary. Staff has also
asked the applicant to verify the location of these ponding areas
on site since they appear to be very close to the wetland edge and
may in fact intrude upon some of the existing wetland vegetation.
if such is the case, staff would be recommending that the ponding
areas be relocated so that there is no disturbance to the existing
wetland area. One suggestion would be to relocate the ponding area
to a more central location such as between the South cul-de-sac and
the loop cul-de-sac where they can be more easily accessed and
maintain more distance from the wetland rather than being located
completely around the wetland edge. Staff is also requesting that
the applicant provide information on the existing drainage
facilities such as culverts to and from the site. Specifically,
the culvert under Lyman Boulevard which will intersect the South
Road cul-de-sac and the outlet culvert to the wetland under Lake
Riley Road.
Staff anticipates a potential drainage problem with the westerly
temporary cul-de-sac for North Road. This portion of the existing ,
site did not previously drain off site to the west." The proposed
street grading plans shows this cul-de-sac and the adjacent 100
feet of North Road to not be serviced by storm sewer. Staff
recommends that this area be reviewed for storm sewer service. If
storm sewer is not feasible, some sort of interim drainage proposal
must be submitted that facilitates this lower area not being
serviced by storm sewer. Staff suggests one alternative being a
temporary overland drainage, via a swale, to the proposed ditch
swale to the rear of Lots 10-14, Block 1.

EROSION CONTROL
' The plans submitted display Type III erosion control over the
entire area bordering the wetland area. Staff is recommending
additional erosion control north of North Road. As mentioned
previously, wood fiber blankets will be required as slope
stabilization measures for all of the rear lots bordering the
wetland area and on all the areas where slopes are 3:1 or greater.
Silt fence erosion control should be installed around any and all
' proposed detention ponds on the project. The entire site should be
reseeded and mulched immediately following completion of the
grading operation.
' LANDSCAPING
The applicant has shown on Sheet 2 of the plans areas of
vegetation. Staff has requested that the applicant provide
detailed information on the areas of vegetation as to the type of
tree and size. The City will require tree removal plans for those
lots with significant vegetation such as Lots 10-16, Block 3 and
the city will require replacement for trees with a caliper of 4 and
over (other than species of shrub trees such as box elder) .
r ' PARK AND RECREATION
On September 25, 1990, the Park and Recreation Commission reviewed
the Lake Riley Hills project (Attachment #2) . The Park and
Recreation Commission recommended that Ldts 21-26, Block 3 be
dedicated as parkland. As part of the dedication, the applicant
will reconfigure lot lines to allow for a contiguous southerly
border and prepare the site according to a grading plan provided by
the City. It was further recommended that the applicant construct
a 5 foot wide concrete sidewalk along North Road and West Road and
provide a 20 foot wide trail easement along Lake Riley Boulevard
and Lyman Boulevard. In return for these requirements, the
applicant will receive a $410 credit on park fees per unit and 100%
' credit on trail fees. The remaining $90 of park fees per unit will
be collected as part of the building permit process. The Park and
Rec Commission also stated that the park and trail requirements
' were for the parcel south of Hwy. 212 and that requirements for the
parcel north of Hwy. 212 will be reviewed at the time it is
developed.
' The Park and Rec Commission has not ¢etermined which side of the
street the sidewalk should be located and this will be determined
by the Engineering Department. Also, the requirement of a 20 foot
wide trail easement along Lake Riley Boulevard and Lyman Boulevard
will not be necessary if the additional right-of-way, as requested
by staff along both Lyman and Lake Riley Boulevard, is provided.
i
Lake Riley Hills

The additional right-of-way requested by staff will also
accommodate any trail improvements along the roads.
The following is a table of the lots and their compliance with the '
Zoning Ordinance.
COMPLIANCE TABLE - LOT SIZES '
The following are lots which do not comply with the Zoning
Ordinance
AREA WIDTH DEPTH
REQUIREMENTS (15,000) (90' ) (125' )
BLOCK 1
Lot 11 26,840 89* 297
Lot 12 26,415 89* 297 __
BLOCK 4
Lot 5 16,841 147 113**
BLOCK 5
Lot 1 28,704 460 50**
* Lot must be adjusted to provide 90' of lot frontage at the lot
line
** Lot must be adjusted to provide 125' lot depth.
Lot 5, Block 4 only has a depth of 113 feet which does not meet the
ordinance requirements of a lot depth of 125 feet. The lot
configuration in Block 4 must be adjusted to provide Lot 5, Block
4 with the required lot depth. Several of the lots do not have the
90 feet of street frontage at the lot line but these are located
along the outside of a curve and the ordinance allows for the 90
feet width to be provided at the 90 foot setback. All of the lots
in question do meet the 90 feet at the 30 foot setback. Lot 10,
Block 1 is a triangular shaped lot and staff is recommending that
this lot be reconfigured to provide four sides to prevent any
difficulty in meeting setbacks when the building permit is applied
for. Lot 1, Block 5, contains a 28,704 square foot lot located
adjacent to Lake Riley. As will be covered in this report, future
improvements to Lake Riley Boulevard requires 27 feet of additional
right-of-way on both sides of the street. The additional 27 feet
taken from Lot 1, Block 5 essentially makes it an unbuildable lot
with less than a 50 foot depth. Therefore, Lot 1, Block 5 should
be designated as an outlot.
WETLAND ALTERATION PERMIT
The proposed subdivision contains a large Class A wetland located
in the southeast corner of the site. The wetland is of high
1
Lake Riley Hills
John Klingelhutz
October 3, 1990
Page 10
quality and is approximately 91/2 acres in size. The Class A wetland
is also a protected wetland by the DNR. Any activity below the
' ordinary high water elevation, which alters the course, current or
cross section of protected waters or wetland is under the
jurisdiction of the DNR and may require DNR protected water permit.
The applicant met on site with the DNR to determine the OHW, which
is now set at 864.7. Upon site inspection, it was determined that
there was a fringe of wetland vegetation beyond the ordinary high
water mark at approximately 866 elevation. Therefore, the wetland
' boundary shall be determined as the 866 elevation and will be
protected by a drainage and utility and conservation easement and
also shown as a "wetland" on the final plat.
The applicant is providing a storm water sedimentation basins to
prevent storm water from being directed directly to the wetland.
This will prevent sedimentation and water level bounces that are
' detrimental to the basin's wildlife values and water quality. As
mentioned previously, staff is recommending that the applicant
stake the extent of the ponding areas on site to verify that the
' ' wetland fringe vegetation is not being altered or disturbed by the
proposed ponding areas. Once it is ensured that the ponding areas
are not impacting the wetland vegetation, staff is comfortable with
' the subdivision in that the proposal will not be impacting the
wetland and will actually be resulting in some improvement once the
gravel driveway dividing the wetland in two is removed.
' The applicant has adjusted the lot areas adjacent to the wetland
since the original submittal to provide for the 75 foot wetland
setback. The majority of the lots adjacent to the wetland do
provide adequate area for a single family residence and an attached
deck or porch. Lots 34 and 35, Block 3 and possibly Lot 36, Block
3 will not have adequate room for a house and a deck. As done with
previous subdivisions with wetlands, staff will recommend a
' condition that the applicant, as part of the development contract,
record restrictions against each lot stating that there is a 75
foot setback from the wetland elevation of 866 contour and that
this elevation shall be shown on all lot surveys when a building
permit is submitted. If porch or patio doors are provided on the
house plans, the lot survey will show how a deck can meet the
' required wetland setback. The proposed ponding areas adjacent to
the wetland will be shallow ditches which will most likely take on
a wetland quality with wetland vegetation. Therefore, staff is
recommending that in addition to the drainage easement that will be
' covering the ponding areas, a conservation easement be located over
the ponding areas and wetland to ensure that the areas are not
altered.

CITY COUNCIL RECOMMENDATION
•
' Staff recommends the City Council approve Preliminary Plat for Lake
Riley Hills Addition with staff's 15 conditions and the four
additional conditions from the Planning Commission.
RECOMMENDATION - WETLAND ALTERATION PERMIT
In summary, the proposal will not be negatively impacting the Class
A wetland located on the site, and in fact, if the existing dirt
driveway bisecting the wetland into 2 is removed, it will actually
ultimately improve the wetland. Therefore, staff is recommending
that the Planning Commission adopt the following motion:
' "The Planning Commission recommends approval of a wetland
alteration permit for Lake Riley Hills subdivision as shown on
plans dated September 4, 1990, with the following conditions:
1. The applicant shall provide a drainage, utility and a
conservation easement over Outlot C and the proposed ponding
areas and that the 866 contour shall be the edge of the

FROM: Charles Folch , Assistant City Engineer
DATE: September 25 , 1990
ISUBJ: Preliminary Plat and Site Plan Review for
Lake Riley Hills Subdivision
File No. 90-27 Land Use Review
1
This site encompasses a total of 78. 24 acres of land north of
Lyman Boulevard in the west half of the northeast quarter of
Section 24. This parcel of land is characterized by a rolling
terrain , randomly spersed stands of trees and a large wetland
1 area located in the southeast corner. The present use of this
land is agricultural with field grasses and some row crops.
The current zoning for this parcel is mixed low-density
residential and single-family. The proposed zoning would be a
composite of single-family residential for the southern
two-thirds of the property and high-density residential for the
1 northern one-third. A large strip of land located through the
northern half of the site has been designated as a corridor for
the future Trunk Highway 212 improvement project. The
1 preliminary plat submitted proposes to plat the southern
two-thirds of the site as residential single-family lots with
the northern portion, in and around the Trunk Highway 212
corridor , being platted as an outlot.
Grading
•
The plan submitted proposes to grade the southern two-thirds of
the site. The grading scheme is proposed to be similar to that
existing which drains primarily southeast into the wetland area.
The steepest resulting slopes will be found on the rear yard
areas of the lots surrounding the wetland area. Special slope
stabilization methods such as wood-fiber blankets and Type III
erosion control will be required in these areas.

In reviewing the grading plan, one major area of concern has I
arisen. This concern relates to the interfacing of this
development with the proposed future Trunk Highway 212 highway
improvement. The applicant was requested to obtain and provide
information from MnDOT detailing the current right-of-way and
plan elevations for this corresponding segment of future roadway.
This information has not been submitted to date; however, some
slope grading is shown on the plan. Staff stresses the need for
the applicant to submit the requested information on the future
Trunk Highway 212 project to verify the compatibility of these
two projects related to right-of-way, grades and elevations .
Staff recommends that the applicant also provide some sort of
noise abatement measures such as earth berming immediately south
of the proposed Trunk Highway 212 alignment.
The property lying north of the Trunk Highway 212 corridor , as
mentioned previously , will be platted as an outlot and proposed
for future high-density residential zoning. No grading is
proposed in this area at this time. A complete site plan review
of thiss area will be made when a future proposal is submitted.
Drainage
As mentioned previously , the majority of the existing site and
the proposed site drains southeast into the wetland area. A
preliminary storm sewer plan has been submitted- for this
subdivision. A review has been made and the corresponding detail
comments and corrections have been outlined on a plan set to be
returned to the applicant' s engineer for revisions. Storm sewer
calculations and runoff rate requirements have also been
submitted for review. The applicant will also need to submit
these grading plans and drainage information to the Watershed
District for review and approval .
Detention ponds are proposed to be constructed in an effort to 1
maintain the predeveloped runoff rate for the site. From
preliminary review, staff is requesting the applicant's engineer
to review the total capacity of these ponding basins needed to
meet the predicted retainage requirements. Another very
important area of concern related to the detention ponds involves
acquiring access to these ponds and their corresponding outlet
structures for maintenance purposes. Staff recommends that the
applicant provide a plan showing designated access points to
these ponding basin areas .
Staff also requests that the applicant provide information on
existing drainage facilities such as culverts to and from the
site. Specifically, the culvert under Lyman Boulevard which will
intersect with the South Road cul-de-sac and the outlet culvert
for the wetland area under Lake Riley Road.

' Staff anticipates a potential drainage problem with the westerly
temporary cul-de-sac for North Road. This portion of the
existing site did not previously drain off-site to the west. The
proposed street grading plan shows this cul-de-sac and the
adjacent westerly 100 feet of North Road to not be serviced by
storm sewer. Staff recommends that this area be reviewed for
storm sewer service. If storm sewer is not feasible, some sort
of interim drainage proposal must be submitted that facilitates
this lower area not being serviced by storm sewer. Staff
suggests one alternative being a temporary overland drainage, via
a swale, to the proposed ditch swale through the rear lots of
Lots 10 through 14 of Block 1.
' Erosion Control
The plans submitted display Type III erosion control over the
entire area bordering the wetland area. Staff is recommending
' the addition of erosion control on the easterly end of the site
north of North Road and on the westerly end of the site north of
North Road. As mentioned previously, wood-fiber blankets will be
required as a slope stabilization measure for all of the rear
lots bordering the wetland area and on all the areas where slopes
are 3:1 or greater. Silt fence erosion control should be
installed around any and all proposed detention ponds on the
r project . The entire site should be re-seeded and mulched
immediately following the completion of the grading operation.
I - Streets
All of the streets within this proposed subdivision have a
' right-of-way scale dimension of 50 feet. Staff recommends that
right-of-way for North Road and West Road be increased to 60 feet
as they are anticipated to function as collector streets in the
future. This width will also facilitate the installation of the
required sidewalk. The dimensions for all streets shall be noted
on the plat to confirm this . The right-of-way for the
cul-de-sacs scale to be approximately 50-foot radiuses. Staff
notes that the current radius of right-of-way for an urban
cul-de-sac is to be 60 feet and that the applicant shall make
this appropriate change.
A review of the street plan has been performed and corresponding
detail recommendations have been noted on the plan set to be
returned to the applicant's engineer for revision. Street widths
on the plans are shown to be 32 feet face-of-curb to
face-of-curb. This is equivalent to the City standard of 35 feet
back-of-curb to back-of-curb for an urban collector street.
While this standard is applicable to North Road and West Road,
the applicant should be advised that the Loop Road, South Road
and south cul-de-sac may be reduced in width to 31 feet
back-of-curb to back-of-curb.

Staff would also like to note that the intersection of South Road '
and West Road will have to be shifted approximately 60 feet to
the north. The centerline for South Road is located
approximately 240 feet north of Lyman Boulevard. City Ordinance
requires that the minimum centerline offset distance between
intersections be 300 feet.
Initially, the only access to the site will be via Lyman
Boulevard. When future development occurs around this site, it
is anticipated that North Road will be extended both to the east
and to the west and provide additional access points to this
subdivision. As mentioned previously, temporary cul-de-sacs will
be installed at the current limits to North Road. Staff also
recommends that barricades be installed at the ends of these
cul-de-sacs and that they be signed designating them to be
temporary pending future road extensions.
The portion of the property north of the Trunk Highway 212 '
corridor to be platted at this time as an outlot will have future
access from Tigua Lane.
There currently exists a private driveway along the easterly
boundary of this subdivision which services a farmhouse located
in the northeast corner of the site. This driveway was
constructed via a dike which bisects the wetland area. It is
anticipated that the proposed Trunk Highway 212 improvement will
require the removal of this farmhouse. In an effort to reunite
the two wetland areas on either side of this private driveway,
staff is recommending that the applicant pursue the possibility
of removing this driveway and dike barrier by contacting and
coordinating with the Department of Natural Resources. A
temporary access to this farmhouse could be acquired along the
property line between Lot 14 and Lot 13 of Block 2 until such
time that the Trunk Highway 212 improvement project removes these
structures.
Utilities
A review has been made of the sanitary sewer and watermain plans
submitted in conjunction with the proposed subdivision. At the
present time, a feasibility study has been authorized by the City
Council , at the request of the applicant, to determine the
feasibility of servicing this area with watermain and sanitary
sewer. A condition of this authorization was for the applicant
to submit to the City a $10 ,000 letter of credit or cash escrow
to guarantee payment of expenses associated with this study (see
attachment) .
This security has not been received to date and as a result the
study has not been initiated. Until the results of this study
are known, it will be inappropriate to make any final approval of
the subdivision proposal .

Page 5
Staff recommends that the applicant's engineer submit the flow
calculations for the sanitary sewer system to verify pipe
capacity and minimum score velocities through all the sewer
' segments within this proposed subdivision. Staff is also
recommending that the applicant 's engineer verify that the
existing lift station and 4-inch forcemain sewer to facilitate
this subdivision is adequate in size and capacity. It should be
noted that the entire development is proposed to be serviced
through gravity sewer; however, the connection point for this
system will be in the vicinity of Lyman Boulevard and Lake Riley
' Road immediately upstream from an existing lift station and
4-inch forcemain.
Sidewalk
The applicant will be required to install a 5-foot wide concrete
sidewalk along the boulevard area on the south side of the
proposed North Road and east side of West Road. The revised plan
submittal should include this information.
Easements _
All of the sanitary sewer and storm sewer extensions through the
' lot areas of the site will require the respective drainage and
utility easements and shall be denoted as such on the plat. The
proposed detention ponds and corresponding access ways will
require pertinent easements . Staff also notes that the temporary
cul-de-sacs at both ends of North Road will require temporary
easements to cover the portions outside of the platted
right-of-way and shall exist until such time that the road
' extensions are constructed and cul-de-sacs removed.
In comparing the proposed plat submitted with the County
half-sections , staff is unable to determine whether a 33-foot
wide segment of land along the north half of Lyman Boulevard has
been previously acquired as right-of-way or acquired by easement.
Nevertheless , preliminary results contained in the Eastern Carver
County Transportation Study (excerpts attached) point to traffic
volumes in excess of 7,400 ADT for this roadway. Its
characteristics rank it as a minor arterial, Class II which will
' require a 120-foot right-of-way (60 feet on each side of
centerline) . It is therefore necessary that a 60-foot wide
right-of-way be granted along the southern border of the proposed
plat. This width would also allow incorporation of the future
trail along Lyman Boulevard.
The aforementioned transportation study designated the segment
of Lake Riley Boulevard north of Lyman Boulevard as also a minor
arterial, Class II roadway. Therefore, a 120-foot wide
right-of-way will also be required for this road segment. This
width would incorporate the future trail . Thus, a separate trail
easement would not be necessary.

As mentioned previously, a temporary driveway easement will need '
to be acquired between Lots 13 and 14 of Block 2 in order to
provide a temporary access for the existing farmhouse.

the findings of the feasibility study are known and the City
Council takes appropriate action to provide municipal water
service to the site.
2 . The applicant shall provide current plan right-of-way, grade

Re: Feasibility Study for Watermain Extension II
Project No. 90-10
Dear Mr. Klingelhutz: II
This letter is in follow-up to the City Council action of July
23 , 1990 wherein they accepted your request for a feasibility
study to evaluate watermain extension to your property located in
the northeast quarter of Section 24 near Lake Riley. The
feasibility study was also directed to evaluate the extension of
II
sanitary sewer service to this area. City Council conditioned
their approval upon receipt of a $10,000 letter of credit or cash
escrow from you to guarantee payment of the expenses associated II with this study.
In discussion with Mr. Bill Engelhardt, this has verbally been
communicated to you earlier but I thought I would document in
II
writing that this study will not be initiated until such time as
the City receives the financial security as required. I would
anticipate the study would take from four to six weeks to be
II
completed so you may want to factor this into your schedule.
If you have any questions in the meantime, please feel free to
call.

TO: JoAnn Olsen, Senior Planner
FROM: Todd Hoffman, Recreation Supervisor
DATE: September 26 , 1990
SUBJ: Lake Riley Hills Project
Park and trail needs in the Lake Riley Hills Addition were
discussed at the September 25 , 1990 Park and Recreation Com-
mission meeting. -Mr. John Klingelhutz , the applicant for this
plat, was present- at this meeting. Upon conclusion of their
discussion the Commission took the following action.
Commissioner Mady moved, Commissioner Robinson seconded
to require Lots 21, 22, 23, 24, 25 and 26, Block 3 , Parcel
' 2 be dedicated as park land. As part of the dedication,
the applicant will reconfigure lot lines to allow for a
contiguous southerly border and prepare the site according
to a grading plan provided by the City. It is further
recommended that the applicant construct a 5 ft. wide
concrete sidewalk along North Road and West Road and provide
a 20 ft. wide trail easement along Lake Riley Road and Lyman
Boulevard. In return for these requirements the applicant
will receive a $410. 00 credit on park fees per unit and a
100% credit on trail fees. The remaining $90.00 of the park
fee per unit will be collected as part of the building permit
process. All voted in favor and the motion carried.
I have attached a copy of the report presented to the Commission
for this item. Your assistance in seeing that the wishes of the
Park and Recreation Commission are fulfilled is appreciated.
Lastly, it is important for all parties involved to realize that
these park and trail requirements are for Parcel 2 only.
' Requirements for Parcel 1 would be addressed at the time it is
developed.

1 BACKGROUND
The Commission initially reviewed this item at the August 21, 1990
meeting. Mark Koegler presented the item that evening. Upon
conclusion of commission discussion, a motion was made which
generally confirmed Mr. Koegler's recommendation (see enclosed
minutes) .
•
Since that time, Engelhardt and Associates, Inc. , the engineering
firm for this project, has been in contact with the city to express
concern over the recommended location of the proposed park. It is
their position that the area north of Outlot C contains some of the
most desirable lots in this plat in regards to sight lines to Lake
Riley, overall position within the subdivision, etc. They are also
concerned that the grade in this area would not be appropriate for
facilities proposed for this park. In reviewing this plat, it is
' evident that these positions are valid to a certain degree and
staff is not opposed to investigating alternative sites for park
land.
' Further conversations with representatives of Engelhardt and
Associates centered on finding a location for a park which met the
needs of all parties. Engelhardt and Associates proposed Lots 1,
11 2, 3 and 4 , Block 3 and Outlots A and B be designated as park land.
This location did not offer much in the category of "desirable
factors" . It would not provide enough flat area for an open field,
it contains considerable slopes and drainageways, the configuration
of the lots is not conducive for park use, it is separated into two
segments by a very narrow strip of land, it lies next to Lyman
Boulevard and it is isolated from the main body of the subdivision.
Engelhardt Associates, Inc. agreed that an alternate location would
serve better as a park. It was at this time that the area around
Lots 22, 23, 24, 25 and 26, Block 3 were discussed. This area
offers numerous benefits over the others being considered. It is
situated on high ground with insignificant slopes, the area is in
the interior of the proposed subdivision and would provide a
pleasing sense of open space for the residents living there. The
' site is also situated on North Road which will provide future
access to the east and west. Initial conversations with Engelhardt
and Associates, Inc. identified Lots 22, 23, 24, 25 and 26 as
potential park land. The site plan attached originally identified
these five lots as park land. In consultation with Mark Koegler,
it was determined that including Lot 21 would be beneficial to• the
development of the park and allow for additional buffer area
between park facilities and adjoining Lots 20 and 27. Thus the
plan now shows Lot 21 to be included in the proposed park land

dedication. Mr. John Klingelhutz, the applicant, has also been in
contact with me concerning this subdivision. Mr. Klingelhutz
initially was somewhat opposed to the dedication of park land. In
concluding our conversation, he said he would like to review the
proposal , but seemed open to the issue of land dedication.
In conversations with both Mr. Klingelhutz and Engelhardt and
Associates, the topic of sidewalks along North Road and West Road
was discussed. It is apparent that pedestrian walkways in these
locations would prove beneficial . Mark Koegler also mentioned the
need for sidewalks along these routes when reviewing this new
location for the proposed park.
RECOMMENDATION 1
Progress in solidifying negotiations to meet the recreational needs
created by this development is significant. City Code allows for .
a requirement of 2 . 76 acres of land be dedicated for park purposes
in the development of parcel II . Parcel I will be considered
separately in the event of future development. Lots 21, 22 , 23 ,
24 , 25 and 26 consist of 2 . 26 acres which represents 82% of the
requirement. Therefore, it is recommended that the Park and
Recreation Commission require Lots 21, 22 , 23 , 24 , 25 and 26, Block
3 ,. Parcel II be dedicated as park land. As part of this
dedication, the applicant will prepare the site according to a
grading plan provided by the city. In return for this dedication,
the applicant will receive a $410. 00 credit on park fees for each
lot. The remaining $90. 00 per lot to be collected as part of the
building permit process. It is further recommended that the
applicant construct a 5 ft. wide concrete sidewalk along North Road
and West Road in lieu of trail fees.

Dear Ms. Olsen:
RE: LAKE RILEY HILLS, LAKE RILEY (10-2P), CITY OF CHANHASSEN,
CARVER COUNTY
We have reviewed the site plans (received July 9, 1990) for the r
above-referenced project (Wz NE4, Section 24, Township 116 North,
Range 23 West) and have the following comments to offer:
1) Protected wetland 10-213W (shown as outlot B) is on the
proposed site. Any activity below the ordinary high water
elevation (OHW) , which alters the course, current, or I
cross-section of protected waters or wetlands, is under the
jurisdiction of the DNR and may require a DNR protected waters
permit. No official OHW has been established for wetland
10-213W. Please contact this office if there is any question
about whether proposed activities will be within protected
wetland 10-213W and we can make arrangements to estimate or
officially determine, if necessary, the OHW.
2) DNR protected wetland 10-213W should be labeled as such in
future plans or plats and the OHW, if available, should be
noted.
3) The project is within the shoreland district of Lake Riley
(10-2P) , which is classified as recreational development. The
City should ensure that the project is consistent with the
local shoreland management ordinance. It does appear that the
minimum lot sizes are met in the proposed plan. ,
4) There should be some type of easement, covenant or deed
restriction for the properties adjacent to the wetland areas.
This would help to ensure that property owners are aware that
the DNR and the Corps of Engineers have jurisdiction over the
area and that the wetlands cannot be altered without
appropriate permits.

11 5) It a ears that the stormwater is bein routed directl , to
PP 9 Y
wetland 10-213W. Stormwater sedimentation/treatment basins,
or other appropriate stormwater treatment features, should be
included in the plan. If stormwater is routed directly to the
wetland it can cause sedimentation and water level bounces that
' are detrimental to the basin 's wildlife values and water
quality.
6) If construction involves dewatering in excess of 10,000 gallons
per day or 1 million gallons per year, the contractor will need
to obtain a DNR appropriation permit. You are advised that it
typically takes approximately 60 days to process the permit
application.
7) Appropriate erosion control measures should be taken during the
construction period. The Minnesota Construction Site Erosion
and Sediment Control Planning Handbook (Board of Water & Soil
Resources and Association of Metropolitan Soil and Water
Conservation Districts) guidelines, or their equivalent, should
be followed.
Thank you for the opportunity to comment. Please contact me at
1 296-7523 should you have any questions regarding these comments.

Lake Riley Hills, Preliminary Plat
Dear Ms. Olsen: I
We are in receipt of the above referenced plat for our review:in accordance with
Minnesota Statutes 505.02 and 505.03 Plats and Surveys. We find the plat acceptable I
for further development with consideration of the following comments: .
- We request the developer to dedicate access control along the proposed I
CSAH 212 corridor prior to approval of the final plat.
- Residential development is a very sensitive land use. Future noise levels I
are expected to violate state standards. The Minnesota Pollution Control
Agency will most likely require that noise abatement be constructed to 111 mitigate noise pollution from TH 212. The City and developer should be
aware that Mn/DOT will not provide noise abatement for new development
adjacent to corridorsthat have been officially mapped. We believe the City
I
and developer should plan to provide noise abatement along TH 212 for this
development.
- The proposed letting date for TH 212 in this area is fall of 1996.
- This development impacts DNR wetlands. DNR, Corps of Engineer and
Riley-Purgatory-Bluff Creek Watershed District permits will be required.
If you have any questions in regard to our review of the plat please call me. I
Sincerely,
cc: Steve Keefe, Metro Council

Dear Owen:
The Planning and Engineering staff have made a review of the
amended plans for Lake Riley Hills. Previously, staff submitted
comments on the first draft requiring additional information. The
following is a list of items which still need to be provided before
a complete plan reveiw can be conducted:
1. The ordinary high water mark of the wetland must be
determined. The DNR can work with you to determine the OHWM.
2. Soil boring information is still required.
3 . Erosion control should be shown as TYP III, not Type I.a III T
4. Temporary cul-de-sacs should be shown on all street ends.
5. Storm water calculations verifying surface water discharge is
' retained to predeveloped rate for 100 year, 24 hour storm.
6. Tie the site into Highway 212 improvement.
7. The Fire Department needs the following information:
a. Fire hydrants shown with -300 foot spacing.
b. City approved street names.
c. Through streets with relation to West 86th Street.
8. Need record information on all existing city utilities that
are proposed to be connected to.
9. Provide information on all existing drainage facilities and
r
r
•
Mr. Owen Carlson

Page 2
culverts on and immediately adjacent to the site. I
10. Provide tree removal plan detailing what type and size of
trees which will be removed. There is a stand of trees around
the south and southeast side of the wetland which need to be
included.
General comments: I
1. The slopes around the ponding areas and wetland are very steep
and will require slope stabilization including wood fiber
blanket. Staff feels the slope is too steep and lots are too
close to the wetland resulting in back yards which cannot be
used by the homeowner. For example, Lots 34 and 35., Block 3,
will not be permitted decks due to the wetland setback.
2. The proposed ponding areas do not provide the City access
points for maintenance. Combining the ponding areas into a
more central accessible site might be preferred.
Please submit revised plans with the above information and the City
will then proceed with the application.
Sincerely,
Jo Ann Olsen Charles Folch
Senior Planner Assistant City Engineer
