This report has been updated since the Planning Commission meeting which took place on
March 17, 1999. All new information will appear in bold lettering and impertinent
information will be stricken out.
PROPOSAL/SUMMARY
There are twa three actions being requested by the applicant. The first request is to subdivide
51.6 acres, Outlot D of Chanhassen Lakes Park Addition into 10 lots. The second is a wetland
alteration permit to fill 1.23 acres, provide 1.62 acres of in kind mitigation and 1.89 public value
credits. The third request is a decision on the need for an Environmental Impact Statement
(E~S).
The site is zoned IOP, Office Industrial Park and is located east of Audubon Road, west of
Powers Boulevard and south of the Twin Cities and Western Railroad.
Access to the subdivision will be provided via an extension of Lake Drive West which will connect
this subdivision with Audubon Road to the west and Powers Boulevard to the east. A cul-de-sac, as
well as driveways, will provide access service to the proposed lots. The subdivision request is a
relatively' straightforward action.
All of the proposed lots meet the minimum area, width, and depth requirements of the Zoning
Ordinance.
A wetland complex, classified as Ag-Urban, occupies the westerly portion of the site. The
applicant is requesting a wetland alteration permit to fill 1.23 acres, provide 1.62 acres of in kind
mitigation and 1.89 public value credits (Public Value Credits include storm water ponds, Buffer
Zones, and restoration of existing wetlands). There are some complex issues associated with the
wetland (refer to the Wetland section of the staff report for a detailed explanation of the issues
and concerns).
The site has a canopy coverage of 2.5 acres excluding the wetland area. Most of the tree coverage
will be lost due to grading and extension of Lake Drive West. A replacement planting plan must
be submitted to the city for approval. Included in the plan shall be location, species and size of
replacements. All replacements must meet minimum size requirements and species suitability
per ordinance.
Boulevard plantings for the development will be required at a rate of one every 30 feet.
Reforestation plantings can be used as boulevard plantings. Exact ordinance requirements for
parking lot and landscaping standards will be reviewed at the time of site plan review for the
individual buildings.

In reviewing this plat, staff required the applicant to submit an Environmental Assessment
Worksheet (EAW). An EAW is mandated if a development exceeds 300,000 square feet in a third
class city (cities of the third class: 10,000 to 20,000 population). After reviewing the document, the
Regulating Governmental Unit (RGU) must determine if there is a need to prepare an
Environmental Impact Statement. After staff reviewed the EAW and based upon the comments
received from the referral agencies, there does not appear to be any issues that would prevent this
project from moving forward. Referral Agencies wi!! have submitted their comments and non
appear to be of any concern, no later than March 27d and the document will then appear before
the City Council on April 12, 1999. Staff recommends that the City Council approve a
Resolution Declaring No Need for an Environmental Impact Statement for the Chanhassen
Lakes Business Park 7th Addition Industrial Office Park.
In summary, staff believes that the proposed subdivision is well designed. Minor revisions will be
required. We are recommending that it be approved with conditions outlined in the staff report.
BACKGROUND
In 1979, the City Council approved a 276 acre industrial park. The park was intended to develop
in three phases. The subject site is the third and final phase. An Environmental Assessment
Worksheet (EAW) was prepared for the site, however, staff was unable to find a record
indicating it was filed. In 1990, Redmond Products began preparing an application to develop
the site and a second EAW was prepared. Shortly after the application was submitted, Redmond
Products withdrew their proposal and the second EAW was not filed. Consequently, staff
required the applicant to prepare a new EAW for the third phase.
PRELIMINARY PLAT FOR CHANHASSEN LAKES BUSINESS CENTER 7TM ADDITION
The applicant is requesting preliminary plat approval to replat Outlot D into 10 lots. The site is
zoned IOP, Office Industrial Park and is located east of Audubon Road, west of Powers
Boulevard and south of the Twin Cities and Western Railroad.
Access to the subdivision will be provided via an extension of Lake Drive West which will connect
this subdivision with Audubon Road to the west and Powers Boulevard to the east. A cul-de-sac, as
well as driveways, will provide access service to the proposed lots. The subdivision request is a
relatively straightforward action and staff is recommending approval with conditions.
WETLANDS
Wetland mitigation submitted by Schoell & Madson, Inc. was conducted on October 7 and 8,
1998. This delineation identified five separate wetland basins along the Eden Trace property.
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 4
Previous city records show only two wetlands on this property and review of the U.S. Fish and
Wildlife National Wetland Inventory Maps indicates three wetlands along this site. The wetlands
are identified into five different basins, all of which would be considered Ag/Urban wetlands
since this entire area was historically drained for agricultural purposes.
Wetland Basin 1 is located on the north side of the property and is approximately. 15 acres in
size. This wetland is a partially drained wetland with seasonal flooding at the time of the
delineation. No free water or standing water was observed in the wetland.
Wetland Basin 2 located on the northwestern portion of the property is 1.45 acres in size. It
would be classified as a Type 2 or seasonally flooded wetland. There was no standing water or
saturated soils but soils test would indicate that during growing seasons this particular wetland
has the necessary hydrology to be classified as a wetland. The proposed plan would partially fill
the southern edge of this wetland.
Wetland Basin 3 located in the central portion of the property is .34 acres in size. This area had
not previously been delineated as a wetland. It would be classified as a Type 3 wetland
seasonally drained/ditched wetland. Again, the delineator observed no standing water in the
wetland at the time of delineation but soils would indicate this area is partially under water
during the spring. This proposal would fill this wetland entirely.
Wetland Basin 4 located on the southern portion of the property is. 1 acres in size. It would be
classified as a Type 2/6 wetland, inland fresh meadow shrub swamp. Again, this is a seasonally
flooded area greatly influenced by previous agriculture activities. No standing water was
observed at the time of delineation. This proposal would fill this wetland entirely.
Wetland Basin 5 is a large area of open water currently with an area of over 4 acres. The actual
size and history of this wetland has become the key issue in the applicant's wetland alteration
permit and site plan proposal.
Historically, this area, like much of the area in Chanhassen, has been farmed. As part of these
agricultural practices, draintiles were installed to drain wetlands and low areas to increase usable
land. As land use shifted away from agricultural activities, the existing wetland was dependent
on the maintenance of these draintile systems. Enclosed you will find historical aerial photos of
this site. These photos show this area had been effectively drained until the 1980's and this
wetland did not exist.
In 1978, the former owners of this property proposed a similar development and prepared a
preliminary EAW. As part of that EAW, the wetland report did not identify any wetland on this
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 5
property. Under current wetland regulations, a property owner could be exempt from wetland
laws if such drainage systems were maintained.
In October of 1998, the applicant approached the LGU for the City of Chanhassen to discuss this
specific wetland on the property. The applicant had requested a drainage exemption from the
Wetland Conservation Act limiting the size of this wetland based on previous construction
activities by the City of Chanhassen. The applicant presented the following argument to the city:
1) The area had been historically drained by draintiles (see historical aerial photos); 2) The
formation of this wetland was not the result of a neglected drainage system on the part of the
landowners, but the result of a draintile broken by a 1993 city utility line construction project.
City records indicate that prior to 1993 a wetland existed similar to the aerial photo of 1991.
This is the size and shape described in the city's wetland identification inventory. After 1993,
however, the wetland has grown in size each year and all indications are that it would continue to
grow until water levels reached that of the railroad drainage system to the north (see attached
1997 photo). Based on that information, staff agreed with the applicant's assessment of the
wetland and directed them to use the 1992 wetland record as the size of the wetland. This
decision is consistent with drainage exemptions outlined in the WCA.
However, once the site plan was introduced for this proposed development it was discovered that
a delineation for a second preliminary EAW was prepared in 1990. This wetland was identified
and a delineation at that time was performed by Progressive Consulting Engineers. In their
notes, they state that they met with a representative from U.S. Fish and Wildlife on the site and
agreed that the assumed border of the wetland was 940. This would be before the city built their
sanitary sewer line indicating that a larger wetland was in existence before the city constructed
the utility line.
This is compelling information that cannot be ignored, however, there are several unanswered
questions about the 1990 determination that must be considered before the city can accept its
findings.
This delineation report has no notes. There is no scientific data on how they came to that
conclusion. It just details that the two parties met on the site and they assumed an elevation as
the wetland edge. In the time since the 1990 findings, wetland science has become a very
technical and exact science. Using data without any notes, there are several different wetland
laws which have gone through several different changes. It is unclear what criteria the
delineators at that time went by to notify the edge of the wetland.
Based on the lack of scientific data to support the 1990 findings, city staff recommends that the
applicant use the city's 1992 wetland identification records as the assumed wetland edge.
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 6
As mentioned previously, all the wetlands identified on site are identified as ag/urban wetlands
by the city's wetland classification system. All the wetlands have been impacted by past
agricultural activities. For this project, the applicant is proposing to fill in 1.62 acres of wetlands.
That means that Basins 3 and 4 would be eliminated entirely. The mitigation for this will take
place along the large basin or Basin 5. Essentially, the mitigation will restore the pond to it's
current size. They are also using stormwater ponds as part of their 2:1 ratio as allowed by the
Wetland Conservation Act.
The wetlands shall be protected by a buffer strip. The width of the buffer strip shall be 0'-20'
with an average of 10 feet. All buildings shall maintain a 40 foot setback from the outside edge
of the buffer strip. Wetland buffer areas shall be surveyed and staked in accordance with the city
ordinance.
GRADING
Most of the site is employed in agricUltural practice. There are isolated groups of trees scattered
throughout the site. As a result of site grading, most of the site (90%+) will be graded for
development. The large wetland located in the westerly portion of the site will not be impacted
for the most part. Mitigation measures are proposed as a result of impacts to the wetlands. The
elevations of the property range from 956 to 900 on the easterly edge of the development. The
average elevation is approximately 946. The grading plans propose to develop building pads,
street subgrade, and stormwater ponds with initial site grading. Due to the grade elevation
difference in the easterly portion of the site, the building pads will be tiered at approximately a 10
to 20 foot elevation difference (Lots 8, 9 and 10). Staff assumes the site grading will be done
with the initial phase due to the volume of earthwork involved. Should earthwork quantities not
balance on site and materials need to be imported or exported from the site, the developer will
need to supply the city with a detailed haul route for review and approval by staff. In addition, if
material is proposed to be hauled off to another location in Chanhassen, it should be noted that
the properties will be required to obtain an earthwork permit from the city.
The plan proposes four stormwater quality ponds for pretreatment of stormwater runoff prior to
discharging into wetlands or offsite water bodies. Staff has reviewed the stormwater pond
locations and have some reservations on two of the four ponds. Staff believes the stormwater
pond proposed "by others" on the city's parkland located south of Lake Drive West should be
eliminated and the stormwater rerouted into the proposed stormwater pond north of Lot 3. The
other ponding area is the pond proposed east of Lot 10. The city has an existing trunk sanitary
sewer line which would run through the middle of the proposed pond. The developer will need
to reconfigure the pond so it is not over the sanitary sewer or, at their cost, have the sanitary
sewer relocated outside of the ponding area. In addition, part of the proposed pond is located on
city property/parkland. The developer will have to reimburse the city either in land and/or
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 7
financially for the portion of the pond on city property. Staff believes a better location for the
stormwater pond would be on Lot 10, however, this would impact the buildable area of Lot 10
significantly. If the pond is relocated to Lot 10, the developer will be entitled to credits against
their stormwater management fees for accommodating stormwater runoff on site. Relocation of
the pond would also lessen the impacts to the existing trunk sewer and Lake Ann Interceptor line
which intersects through the parcel. Staff received a letter from the Department of Natural
Resources explaining that grading activities are taking place within the shore impact zone for
Riley Creek, as well as, filling in the flood way. Relocating the pond, will also address the
Department of Natural Resources concerns regarding shore land impact zone and modifying the
flood plain. Riley creek is classified by the DNR as a tributary stream. The shore impact zone
for tributary rivers or streams, is 50 feet or half of the building setback. This project keeps all
buildings and impervious surfaces between 180 and 200 feet of the Ordinary High Water Level
of Riley Creek.
The grading of Lake Drive West will involve construction activities outside the development.
The developer will need to acquire temporary construction easements from the adjacent property
owners for construction activities outside of the site. Staff will be working wi~t,l~he applicant to
revise street grades between Lot 10 and Powers Boulevard to minlm-i~e the grading outside of the
right-of-way. The use of retaining walls or other embankment measures may also be utilized to
minimize grading and tree loss.
Earth berms ranging from two to four feet high are proposed along the north side of Lake Drive
West except adjacent to the wetland on Lot 5.
The grading plan denotes the normal water elevation of the wetlands and stormwater ponds. The
plans shall be revised to include the high water level of all wetlands and/or stormwater ponds.
DRAINAGE
The city has received a petition from the developer to construct Lake Drive West and the
infrastructure necessary to service this development. A feasibility study was prepared and
received by the City Council on March 8, 1999. A public hearing for the Lake Drive West
improvement project is scheduled for March 22, 1999, at which time the City Council will decide
whether or not to order the project. In conjunction with the city's improvement project, a series
of storm sewer systems will be designed to convey surface water runoff from the individual lots
to the regional stormwater ponds proposed in the development for pretreatment prior to
discharging into wetlands or downstream water bodies. The city's storm sewer system in Lake
Drive West will act as a trunk storm sewer system. Individual storm sewer leads will be
extended to the lots and "A" Street for the developer to utilize. The applicant's engineer will be
working closely with staff to coordinate pipe sizing and pipe location for each lot.
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 8
The development's storm sewer system shall be designed for a 1 O-year, 24-hour storm event.
Ponding calculations including pre- and post-development runoff conditions for a 1 O-year and
100-year, 24-hour storm event have been submitted for city staff review. Revised ponding
calculations will be necessary with the redesign of any stormWater ponding or wetland area
The plans propose four stormwater treatment facilities to pretreat runoff prior to discharging into
the wetlands. Staff has reviewed the locations of the ponds and recommends that the easterly
pond on Lot 10 be redesigned to avoid impacts with the existing sanitary trunk line which is
located parallel to the east line of Lot 10. Another option would be for the applicant to have
trunk sanitary sewer lines reinstalled outside of the pond area. The other ponding area staff
recommends be omitted is the pond proposed south of Lake Drive West within the city's park
property. Staff believes that the storm sewer system can be redesigned to drain northerly into the
proposed water treatment pond located north of Lot 3.
Given the size of this development, staff recommends that an interim drainage and erosion
control plan be developed to provide temporary stormwater ponds during the grading activities.
Revised plans should be submitted to staff and the Watershed District for review and approval in
conjunction with final plat consideration. Emergency overflows from all storm water ponds and
wetlands will also be required.
UTILITIES
Municipal sewer and water service borders the parcel. A trunk sanitary sewer line follows the
proposed alignment of Lake Drive West. Municipal water service is available along Powers
Boulevard and Audubon Road. In accordance with the city's Comprehensive Water Plan, a 12-
inch diameter trunk watermain is proposed to connect (loop) the water system between Powers
Boulevard and Audubon Road. The trunk water system will provide adequate water service for
the proposed development and adjacent properties. Trunk watermain is proposed to be installed
under the city's public improvement project with Lake Drive West. The developer will be
responsible for extending sewer and water improvements along "A" Street and provide service to
the interior lots of the development. The extension of utilities throughout this plat will require
submittal of detailed construction plans and specifications in accordance with the city's latest
edition of Standard Specifications and Detail Plates for staff review and City Council approval.
The construction plans and specifications will need to be submitted a minimum of three weeks
prior to final consideration.
Utility improvements located within "A" Street upon completion will become city maintained
and owned. Individual sewer and water services through each lot shall be privately owned and
maintained. Building permits will be required from the city's Building Department for the
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 9
private utility portion of the project. Drainage and utility easements shall be dedicated over the
public utility lines outside of the right-of-way on the final plat. Depending on the depth of the
utilities, the minimum drainage and utility easement width shall be 20 feet wide.
STREETS
The developer has petitioned the city to construct the street and utility improvements for Lake
Drive West which is listed as a collector street on the city's Comprehensive Transportation Plan.
Lake Drive West is also a Municipal State Aid Route. Lake Drive West is proposed to be
constructed in accordance with the city's Urban/Industrial Street Section which is a 9-ton road
design, 36-foot wide face-to-face street section, boulevard street lighting and landscaping. An 8-
foot wide bituminous trail will also be constructed along the northerly right-of-way line of Lake
Drive West. Landscaping under the city's project will be limited to the city's parkland area.
A preliminary traffic study/investigation was performed in conjunction with the EAW for the
Redmond site plan back in 1990. Staff has required the developer to update the traffic study to
reflect this proposal and determine the full impacts of the project. According to the preliminary
traffic study, development of this property will generate traffic numbers to support the need for a
traffic signal at Lake Drive West and Powers Boulevard. The city's feasibility report for Lake
Drive West did not take into account a traffic signal along Powers Boulevard (County Road 17).
The city and county will have to coordinate the installation of a traffic signal to accommodate
trip generations from the site. It is recommended that the developer be required to escrow with
the city a financial guarantee for a share, based on traffic generated from the site, of the local cost
participation for a traffic signal at Lake Drive West and Powers Boulevard. The city's local
participation cost of the traffic signal is not known at this time. Preliminary estimates between
the city and county should be used for a security escrow. A condition to address this issue will
be placed in the development contract. Once a final traffic study is completed to address the
traffic related issues as a result of this development, staff will be able to incorporate a
methodology to determine the developer's share for a future traffic signal. The city has
previously required security escrow from the developers' of the Chanhassen East Business Center
and Chanhassen Business Center for this same scenario. Based on the updated traffic study
dated March 29, 1999, the existing street systems can adequately accommodate the
additional traffic volume generated by the proposed development (assuming upgrading
Highway 5 to 4 lanes). However, the Lake Drive West/Powers Boulevard intersection will
operate at a level of service E. For most agencies in the Twin Cities area, level of service D
represents the minimal acceptable level of service for regular daily operations. Measures to
alleviate congestion are initiated when intersections experience service E or F conditions.
The city will be constructing Lake Drive West between Audubon Road and Powers Boulevard.
The developer will be dedicating the necessary right-of-way width (80 feet) along Lake Drive
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 10
West with the plat. "A" Street is proposed to be constructed by the developer as part of the
overall development improvements. Boulevard lighting and sidewalk/trail should also be
included as street improvements required along "A" Street. The streets lights should be the city's
standard industrial/collector-type street light which is a 25-foot high corten steel street light.
Locations of the street lights will be determined by staff and the developer at the construction
plan review stage. The lights are typically staggered 200 feet apart on both sides of the street.
According to the preliminary plat for Chanhassen Lake Business Park 7th Addition, "A" Street
measures 50-feet wide (right-of-way). The subdivision ordinance requires a 60-foot wide right of
way. The developer will need to amend the plat to provide for a 60-foot wide right-of-way along
"A" Street. The right of Way along Audubon Road is not clearly defined on the preliminary plat.
A 50 foot wide right of way is required. The city has previously acquired easements (trail/right
of way) with past projects along Audubon Road. The final plat shall denote easements of records
and dedicate a 50 foot wide right of way for Audubon Road.
Upon review of the individual driveway access points along Lake Drive West, staff is generally
comfortable with the locations with the exception of Lot 8 onto Lake Drive West. Since Lake
Drive West is a collector road which will carry higher volumes of traffic, access points should be
limited whenever possible. Staff believes Lot 8 should relocate the access from Lake Drive West
to "A" Street.
Staff has also reviewed the access needs from the surrounding parcels. The parcel immediately
to the south and east of the site (Lake Susan Hills Partnership) is guided for R12 land use. Lake
Drive West roadway improvement will adequately serve the needs of that parcel. The individual
driveway access points will be reviewed at time of site plan approval. The city's park property
directly south of Lake Drive West is proposed to have a parking lot constructed in conjunction
with the city's improvement project for Lake Drive West. The other city parkland, east of the
site, will not have any driveway access. Staff also reviewed the access needs for the Stockdale
parcel which is located west of the site on Audubon Road. The developer is providing an
ingress/egress easement over Lots 2 and 3, Block 1 as a secondary access for the Stockdale parcel
through Lot 2, Block 1 out to Lake Drive West to eliminate the need for additional access points
along Audubon Road. A cross access easement will need to be prepared and recorded by the
developer in favor of the property owner (Stockdale).
"A" Street shall be designed and constructed by the developer in accordance with the city's
Standard Specifications and Detail Plates. Detailed construction plans and specifications for the
streets and utilities to be constructed by the developer will require staff review and City Council
approval. The developer will also be required to enter into a development contract with the city
and provide a financial security in the form of a letter of credit or cash escrow to guarantee site
improvements. Preliminary and final plat approval should be contingent upon the City Council
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 11
ordering and awarding Public Improvement Project No. 98-16 (Lake Drive West) to service this
development. Without the extension of Lake Drive West and the associated utilities, this
development should be considered premature.
EROSION CONTROL
Erosion control measures are proposed throughout the site. Due to the terrain and the amount of
grading, additional erosion control measures may be necessary. Staff believes that a temporary
sediment and erosion control plan should be developed which includes temporary sediment
ponds, phasing of grading operations, and restoration be prepared by the developer. Type III
erosion control fence will be required adjacent to the wetland areas. Stormwater ponds and/or
temporary detention ponds shall be constructed with the initial grading phases to minimum
erosion potential to the wetlands or downstream water bodies. Erosion control blanket will be
required on slopes greater than 3:1. Revegetation of exposed slopes should occur immediately
after grading is completed in accordance with the City's Best Management Practice Handbook.
SWMP
Storm Water Quality Fees
The SWMP has established a water quality connection charge for each new subdivision based on
land use. Dedication shall be equal to the cost of land and pond volume needed for treatment of the
phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction
shall be based upon a schedule in accordance with the prescribed land use zoning. Values are
calculated using market values of land in the City of Chanhassen plus a value of $2.50 per cubic
yard for excavation of the pond. The proposed SWMP water quality charge of $4,633/acre for
office industrial developments will be waived if the applicant provides water quality treatment
according to the city's SWMP standards. The stormwater quality pond shall be designed to retain
60% to 75% phosphorus according to the Walker Pondnet model.
Storm Water Quantity Fees
The SWMP has established a connection charge for the different land uses'based on an average
city-wide rate for the installation of water quantity systems. This cost includes land acquisition,
proposed SWMP culverts, open channels and stormwater ponding areas for runoff storage.
Commercial developments will have a connection charge of $4,360 per developable acre. The total
gross area of the property is 51.6 acres. Therefore, the proposed development would then be
responsible for a water quantity connection charge of $224,976. The actual fee will be determined
upon submittal of the final plat. This fee will be due payable to the city at time of final plat
recording.

Developer does not meet minimum canopy coverage allowed, therefore the difference is
multiplied by 1.2 to calculate the required replacement plantings.
Difference in canopy coverage 4.0 ac.
Multiplier 1.2
Total replacement 5.0 ac.
Total number of trees to be planted 200 trees
A replacement planting plan must be submitted to the city for approval. Included in the plan
shall be location, species and size of replacements. All replacements must meet minimum size
requirements and species suitability per ordinance.
Boulevard plantings for the development will be required at a rate of one every 30 feet.
Reforestation plantings can be used as boulevard plantings. Exact ordinance requirements for
parking lot and landscaping standards will be reviewed at the time of site plan review for the
individual buildings.
LIGHTING
Lighting locations have not been illustrated on the plans. Only shielded fixtures are allowed as
required by ordinance. A detailed lighting plan should be submitted. Street lights consistent
with Lake Drive East and West will be at 200 feet intervals, staggered from one side to the other.
SIGNAGE
The applicant has not submitted a signage plan. One ground low profile business sign is
permitted per lot. The area of the sign may not exceed 80 square feet and a height of 8 feet.
Also, one wall mounted sign per business shall be permitted per street frontage. The total display
area shall not exceed 15% of the total area of the building wall upon which the signs are
mounted. No sign may exceed 90 square feet. Staff is recommending the following criteria be
adopted:
Chanhassen Lakes Business Center 7th Addition
March 17, 1999
Page 13
1. All businesses shall share one monument sign per lot. Monument signage shall be
subject to the monument standards in the sign ordinance.
2. Wall signs are permitted on no more that 2 street frontages.
3. All signs require a separate permit.
4. The signage will have consistency throughout the development and add an
architectural accent to the building.
5. Consistency in signage shall relate to color, size, materials, and heights.
6. No illuminated signs within the development may be viewed from the residential
section south of the site.
7. Back-lit individual letter signs are permitted.
8. Only the name and logo of the business occupying~tbdmnit will be permitted on
the sign.
The applicant must obtain a sign permit prior to erecting the signs on site. One stop sign must be
posted on the driveway at the exit point of both sites. A detailed sign plan incorporating the
method of lighting, acceptable to staff should be provided prior to requesting a building permit.

PARK AND TRAIL
The Comprehensive Park Plan identifies this site as lying within the park service areas of Lake
Susan Park and Sunset Ridge Park. Sunset Ridge Park is situated across the street from this site.
The Comprehensive Trail Plan identifies an east/west connecting link along Lake Drive. On
other sections of Lake Drive, this walkway/trail is constructed as a concrete sidewalk. This
section of walkway will be developed as a component of the new section of Lake Drive.
The Park & Recreation Commission recommended the city require payment of full park and trail
dedication fees for Chanhassen Lakes Business Park 7th Addition.

Findings of Fact Regarding
Decision on Need for Environmental Impact Statement
PROJECT DESCRIPTION
Eden Trace is proposing to develop an Industrial Office Park consisting of 10 buildings
with a gross area of 380,000 square feet.
The project is located east of Audubon Road, west of Powers Boulevard and south of the
Twin Cities and Western Railroad. Primary access will be from proposed Lake Drive
West.
The project site has an area of 51.6 acres and is zoned Industrial Office Park (IOP).
The site will maintain a significant amount of undeveloped land on site. Some of the
primary environmental impacts deal with traffic generated from the development and
described in greater detail within the applicable categories of the EAW.
Existing Tree Canopy Cover - Existing canopy cover is approximately 2.5 acres or 0.06%
of the site. All trees are proposed to be removed and replaced..
Site Preparation - Site grading will occur on the entire site. Erosion control measures will
be constructed prior to initiation of site grading and will remain in place through the
construction process.
Storm Water Runoff- Storm water runoff is proposed to be distributed to four ponding
areas on site to provide sediment and/or nutrient removal.
Wetlands - The proposed site plan will impact 1.23 acres, provide 1.62 acres of in kind
mitigation and 1.89 public value credits.

II. REASONS FOR ENVIRONMENTAL REVIEW
The Chanhassen Lakes Business Park 7th Addition project meets and exceeds the state
Environmental Assessment Worksheet (EAW) threshold for Industrial/Commercial/Institutional
Facilities (Minnesota Rule 4410.4300, Subp. 14). Pursuant to Minnesota Rule 4410.1000, Subp.
4, the Chanhassen Lakes Business Center 7th Addition EAW addresses the cumulative impacts of
the project.
III. ENVIRONMENTAL REVIEW PROCESS
The Chanhassen Lakes Business Center 7th Addition EAW was submitted to the Environmental
Quality Board on February 8, 1999. The EAW Notice of Availability was published in the
February 22, 1999 issue of the Minnesota EOB Monitor. Copies of the EAW were mailed to all
of the agencies and organizations on the EQB official EAW distribution list. The 30-day
comment period ended on Mach 22, 1999.
IV. COMMENTS ON THE EAW
During the comment period, letters of comment were received from the following agencies,
organizations and individuals:
Metropolitan Council
Minnesota Historical Society
Minnesota Department of Natural Resources
Minnesota Department of Transportation
The comment letters on the Chanhassen Lakes Business Park 7th Addition EAW are attached.
The following is a summary of the comments received and responses to the comments.
A. Metropolitan Council
The Metropolitan Council Environmental Services (MCES) has its interceptor located on
the eastern part of the proposed development. They commented that prior to any grading
on the site, detailed grading plans must be provided to the MCES for approval. They t.lso
stated that they concluded that the EAW is complete and accurate with respect to regional
concerns and raises no major issues of consistency with Council policies. They conclude
that an EIS is not necessary for regional purposes.
RESPONSE: The record has been amended to indicate that approvals by the MCES will
be required as part of the project (condition #16).
Chanhassen Lakes Business Park 7th Addition
March 17, 1999
Page 18
B. Minnesota Historical Society
The Minnesota Historical Society commented that there are no properties listed on the
National or State Registers of Historic Places, and no known or suspected archaeological
properties in the area that will be affected by this project.
C. Minnesota Department of Natural Resources (DNR)
The DNR states that the eastern side of the site is within 300 feet of Riley Creek.
Activity within 300 feet of Riley Creek falls within the designated Shoreland
Management District. All city shoreland management requirements need to be met, with
particular emphasis on review of the proposed activities in the "shore impact zone" and
the amount of impervious surface. Also, the project could result in floodplain impacts.
RESPONSE: As mentioned in the grading section of the staff report, relocating the
pond, will address the Department of Natural Resources concerns regarding shore land
impact zone and modifying the flood plain by moving grading activities outside the area
of concern. Riley creek is classified by the DNR as a tributary stream. The shore impact
zone for tributary rivers or streams, is 50 feet or half of the building setback. This project
keeps all buildings and impervious surfaces between 180 and 200 feet of the Ordinary
High Water Level of Riley Creek.
D. Minnesota Department of Transportation
They stated that the EAW is acceptable with consideration that the city will evaluate the
traffic facilities as part of the preliminary plat review. They also requested the
opportunity to review the preliminary plat and any associated traffic studies to determine
if they will require additional turn lanes on T. H. 5.
Response: The applicant has submitted an updated traffic study. A copy has been
forwarded to MnDOT. As individual site plans are reviewed, MnDOT will be consulted
as a referral agency.
V. FINDINGS OF FACT/DECISION ON NEED FOR EIS
Minnesota Rule 4410.1700, Subp. 7, specifies the following criteria to be used in deciding
whether a project has the potential for significant environmental effects.
Type, extent and reversibility of environmental effects.
Cumulative potential effects of related or anticipated future projects.
Chanhassen Lakes Business Park 7th Addition
March 17, 1999
Page 19
The extent to which environmental effects can be anticipated and controlled as a result of
other environmental studies undertaken by public agencies or the project proposers of an
EIS previously prepared on similar projects.
Based on the information contained in the EAW, comments received on the EAW, and the
criteria listed above, the City of Chanhassen, as the RGU makes the following determinations:
A. The project does not have the potential for significant environmental effects.
The preparation of a State Environmental Impact Statement on the project is not needed
or recommended.
Co
The City of Chanhassen may issue permits to allow construction in compliance with the
rules of the EAW and in conformance with the Minnesota Environmental Policy Act.
PLANNING COMMISSION UPDATE
On March 17, 1999, the Planning Commission unanimously~'~t~IViewed and
application.
approved this
A resident on Ibis Court stated that he was concerned the drainage water would increase on his
cul-de-sac due to the new development. David Hempel explained that this development will
reduce the amount of water that drains through the backyards of Ibis Court due to collection of
storm water runoff into the proposed storm drainage system i.e, storm sewers/ponds.
The Commission asked if the proposed development met the buffer ordinance requirements.
Staff explained that it did. The ordinance required a 30 foot buffer strip and the applicant is
providing that. Staff also explained that the applicant will be required to provide boulevard
planting as required by ordinance.
Staff was directed to ensure a sidewalk is extended along A street. A condition has been added
to that effect.
Commissioners also stated that the applicant should design the buildings in a fashion that would
minimize views of the loading docks from the residential neighborhood. Staff explained that the
concept plan submitted by the applicant locates the loading docks in the least visible areas of the
site.

RE: Redmond Products Office/Warehouse in Chanhassen, Minnesota;
Permission to Discharge Fill into Wetlands
Dear Mr. Reiter:
The purpose of this letter is to submit an application for a Section 404
permit to discharge fill material into type PEMC and POWF/EMF wetlands
under jurisdiction of the Army Corps of Engineers. The placement of
fill material in the wetlands is needed to construct a new
office/warehouse and parking facilities for Redmond Products complex in
Chanhassen, Minnesota. The proposed project site is approximately 65
acres of Outlet D, Section 14, Township i16N, Range 23W. It is located
south of State Highway No. 5 between County Road No. 17 and Audubon Road
{immediately south of railroad tracks, see Exhibit A & B).
Existing Site Conditions
Existing conditions at the site consist mostly of open field uplands. A
treeline runs east-west along the half-section line. The area noKth of
this treeline is unused field consisting of grasses and goldenrod. The
area south of this treeline is pasture that appears grazed. One small
wetland {type PEMC) is situated on the northwest corner of the property
at the west end of the treeline. This wetland is approximately 1,1
acres. Some of the wetland appears to be grazed. On the east end of
the wetland there is significant shrub-type vegetation consisting of
mostly sumac. Another wetland is situated on the west end of the
property south of the treeline. It is approximately 5.0 acres of type
PEMC wetlands, with approximately 1.1 acres of POWF/EMF wetlands
contained in the PEMC wetland. The entire wetland area appears to be
grazed pasture area. The 940 contour was assumed as the g6neral
boundary of the wetland area as agreed upon during a field visit by you
and Paul Burke of the U.S. Fish and Wildlife Service. The 940 contour
encompasses approximately 6.1 acres. Also, the 940 contour was assumed
as the approximate boundary for the wetland of 1.1 acres in the
northwest corner of the property. No standing water was evident in
either wetland at the time of the field visit on November 11, 1989.

Proposed Construction
Ryan Construction is proposing to construct for Redmond Products a
370,000 squ~re foot office/warehouse complex along with 360,000 square
feet of paved areas which includes parking area and service roads.
Future expansion of this complex will add an additional 130,000 square
feet of warehouse space. The site layout and proposed grading is shown
in Exhibit E. The necessary layout was dictated by product flow as
determined by Redmond Products.
Need for Project
The new office/warehouse is required by Redmond Products because of
limitations in their present location. The present building is only
106,000 square feet, and the proposed new complex will provide 370,000
square feet. Because of the limited space in the present location, the
client is required to rent storage space at separate sites. The new
complex will allow Redmond Products to consolidate their production,
storage, and distribution into one location. ~_~
AlternatiYes to the Project
Several possible sites were reviewed in Chaska and Chanhassen, and this
particular site is considered the only suitable site for several
reasons. It would be most desirable for Redmond Products to remain in
Chanhassen. The client desired possible rail access, which this site
provides. Also of consideration in choosing a Chanhasseh site was the
fact that most of the employees live in the Chanhassen area. This
particular site was chosen because it was the last remaining large,
suitable site available within the Metropolitan Urban Service Area
(MUSA} boundary within Chanhassen.
Alternatives in the site layout were also considered. As stated
earlier, the proposed layout is required for proper product flow as
determined by the client. Dividing the building and having separate
structures around the site is not an option because it would greatly
hamper product flow and distribution capabilities. The present layout
as proposed on Exhibit E and the location of the complex on the property
is the result of revisions that took into account minimiz~ng.wetland
filling, while accommodating the present topography. The building site
plan was revised after a meeting with Paul Richart and again after a
site visit on November 11, 1989 with the Corps and U.S. Fish and
Wildlife representatives. It must be noted that the building cannot be
moved further east because of the large change in elevations at this end
of the site. Along one line, elevations change 52 feet (900 to 952)
within 550 measured horizontally. The proposed location and layout
provides the least filling of wetland while accommodating the needs of
the client.

Mitigation .
The proposed grading and site plan {Exhibit E) reflects an effort to
mitigate for wetlands that will be affected by this project. The
smaller wetland of 1.1 acres in the NW corner of the property will be
partially filled. To compensate, grading will be done to move the 940
contour southeast to provide a wetland area of approximately 1 acre.
Also, the portion to be filled will first be stripped of the topsoil,
and this .topsoil will be placed in the newly created area of the
wetland. Some landscaping consisting of trees and bushes will be
provided around the wetland.
The larger wetland of approximately 6.1 acres will be more significantly
altered, and so the mitigation plan is more involved. The plan involves
supplying storm water to the wetland area via a settling or "buffer"
pond. This will require lowering the elevation of the wetland. First,
the muck and topsoil of the existing wetland will be stripped and
stockpiled. Then the wetland area-will be regraded to a lower elevation
and the original topsoil replaced in the new wetland area. The bottom
of the regraded wetland will be 930. A soil boring taken in the
northeast end of the wetland {Boring 6, Exhibit B, Boring Log Exhibit D)
gave a water level elevation of 930. Assuming this to be constant in
the existing wetland area, and considering this to be a little low from
the recent drought, the new wetland should have some standing water at
all times. The drainage from the buffer pond will add additional
runoff. An outlet with an invert elevation of 933.0 will act as an
overflow. Calculations show that a lO0-year flood will create a
highwater elevation of 933.3, corresponding to a bounce of 0.3 feet.
The maximum depth in the wetland is expected to be 3.3 feet.
In designing the regraded wetland, consideration was given to artificial
wetland features. An irregular shoreline was provided, especially in
the"range of 933 elevation. Also in this range, an average shoreline
slope of 15:1 was provided. One earthen island with average side slopes
of approximately 10:1 was provided. Finally, a vegetative buffer of
trees and bushes will be installed on the 5:1 slope between the 934
contour and the paved areas bordering the wetland area. The new wetland
area will be approximately 2.5 acres.

Conclusions
The construction of the proposed Redmond Products office/warehouse and
parking facilities will result in the filling and alteration of PEMC and
POWF/EMF wetlands. The 1.1 acre wetland will be partially filled and
then expanded in a different direction for a net loss of about 0.1 acre
of wetland area. The 6.1 acre wetland will be partially filled and
lowered, with a net loss of about 3.6 acres of wetland area. The
unavoidable loss of wetland area will be compensated for as much as
possible by creating a quality artificial-type wetland. Therefore, Ryan
Construction requests that the Corps issue a nationwide permit to fill
approximately 3.7 acres of wetland at the site of the proposed Redmond
Products office/warehouse.
A completed application form for a Section 404 permit is enclosed.
Please call me should you have any questions.
Sincerely,
!

Review of Preliminary Plat for Chanhassen Lakes Business Park 7th
LUR File No. 99-4
Upon review of the plans prepared by Schoell & Madson dated January 25, 1999, I
offer the following comments and recommendations:
GRADING
Most of the site is employed in agricultural practice. There are isolated groups of
trees scattered throughout the site. As a result of site grading, most of the site
(90%+) will be graded for development. The large wetland located in the
westerly portion of the site will not be impacted for the most part. Mitigation
measures are proposed as a result of impacts to the wetlands. The elevations of
the property range from 956 to 900 on the easterly edge of the development. The
average elevation is approximately 946. The grading plans propose to develop
building pads, street subgrade, and stormwater ponds with initial site grading. Due
to the grade elevation difference in the easterly portion of the site, the building
pads will be tiered at approximately a 10 to 20 foot elevation difference (Lots 8, 9
and 10). Staff assumes the site grading will be done with-the initial phase due to
the volume of earthwork involved. Should earthwork quantities not balance on
site and materials need to be imported or exported from the site, the developer will
need to supply the City with a detailed haul route for review and approval by staff.
In addition, if material is proposed to be hauled off to another location in
Chanhassen, it should be noted that the properties will be required to obtain an
earthwork permit from the City.
The plan proposes four stormwater qtmlity ponds for pretreatment of stormwater
runoff prior to discharging into wetlands or offsite water bodies. Staff has
reviewed the stormwater pond locations and have some reservations on two of the
four ponds. Staff believes the stormwater pond proposed "by others" on the City's
parkland located south of Lake Drive West should be eliminated and the
stormwater rerouted into the proposed stormwater pond north of Lot 3. The other
ponding area is the pond proposed east of Lot 10. The City has an existing trunk
sanitary sewer line which would run through the middle of the proposed pond.
The developer will need to reconfigure the pond so it is not over the sanitary sewer
or, at their cost, have the sanitary sewer relocated outside of the ponding area. In
addition, part of the proposed pond is located on City property/parkland. The
developer will have to reimburse the City either in land and/or financially for the
City qf Chanhassen. ,4 ~rvwi,~ commu,io, w/th cleo,/akes, qua/itl, schoo& a cha,nin~ downtown, thrivin~ businesses, and beaut!fid parks. A ~(reat place to live, work, and play.

portion of the pond on city property. Staff believes a better location for the
stormwater pond would be on Lot 10, however, this would impact the buildable
area of lot 10 significantly. If the pond is relocated to all on Lot 10 the developer
will be entitled to credits against their stormwater management fees for
accommodating stormwater runoff on site. Relocation of the pond would also
lessen the impacts to the existing trunk sewer and Lake Ann Interceptor line, which
intersects through the parcel.
The grading of Lake Drive West will involve construction activities outside the
development. The developer will need to acquire temporary construction
easements from the adjacent property owners for construction activities outside of
the site. Staff will be working with the applicant to revise street grades between
Lot 10 and Powers Boulevard to minimize the grading outside of the right-of-way.
The use of retaining walls or other embankment measures may also be utilized to
minimize grading and tree loss.
Earth berms ranging from two to four feet high are,p.r~ ~osed alt~/~ the north side
of Lake Drive West except adjacent to the wetland on Lot 5.
The grading plan denotes the normal water elevation of the wetlands and
stormwater ponds. The plans shall be revised to include the high water level of all
wetlands and/or stormwater ponds.
DRAINAGE
The City has received a petition from the developer to construct Lake Drive West
and the infrastructure necessary to service this development. A feasibility study
was prepared and received by the City Council on March 8, 1999. A public
hearing for the Lake Drive West improvement project is scheduled for March 22,
1999 at which time the City Council will decide whether or not to order the
project.. In conjunction with the City's improvement project, a series of storm
sewer systems will be designed to convey surface water runoff from the individual
lots to the regional stormwater ponds proposed in the development for
pretreatment prior to discharging into wetlands or downstream waterbodies. The
City's storm sewer system in Lake Drive West will act as a trunk storm sewer
system. Individual storm sewer leads will be extended to the lots and "A" Street
for the developer to utilize. The applicant's engineer will be working closely with
staff to coordinate pipe sizing and pipe location for each lot.
The development's storm sewer system shall be designed for a 10-year, 24-hour
storm event. Ponding calculations including pre- and post-development runoff
conditions for a 10-year and 100-year, 24-hour storm event have been submitted
Sharmin A1-Jaff
March 10, 1999
Page 3
for City staff review. Revised ponding calculations will be necessary with the
redesign of any stormwater ponding or wetland area
The plans propose four stormwater treatment facilities to pretreat runoff prior to
discharging into the wetlands. Staff has reviewed the locations of the ponds and
recommends that the easterly pond on Lot 10 be redesigned to avoid impacts with
the existing sanitary trunk line which is located parallel to the east line of Lot 10 or
another option would be for the applicant to have trunk sanitary sewer lines
reinstalled outside of the pond area. The other pOnding staff recommends be
omitted is the pond proposed south of Lake Drive West within the City's park
property. Staff believes that the storm sewer system can be redesigned to drain
northerly into the proposed water treatment pond located north of Lot 3.
Given the size of this development, staff recommends that an interim drainage and
erosion control plan be developed to provide temporary stormwater ponds during
the grading activities. Revised plans should be submitted to staff and the
Watershed District for review and approval in conjunction with final plat
consideration. Emergency overflows from all storm water ponds and wetlands will
also be required.
UTILITIES
Municipal sewer and water service borders the parcel. A trunk sanitary sewer line
follows the proposed alignment of Lake Drive West. Municipal water service is
available along Powers Boulevard and Audubon Road. In accordance with the
City's Comprehensive Water Plan, a
12-inch diameter trunk watermain is proposed to connect (loop) the water system
between Powers Boulevard and Audubon Road. The trunk water system will
provide adequate water service for the proposed development and adjacent
properties. Trunk watermain is proposed to be installed under the City's public
improvement project with Lake Drive West. The developer will be responsible for
extending sewer and water improvements along "A" Street and provide service to
the interior lots of the development. The extension of utilities throughout this plat
will require submittal of detailed construction plans and specifications in
accordance with the City's latest edition of Standard Specifications and Detail
Plates for staff review and City Council approval. The construction plans and
specifications will need to be submitted a minimum of three weeks prior to final
consideration.
Utility improvements located within "A" Street upon completion will become City
maintained and owned. Individual sewer and water services through each lot shall
be privately owned and maintained. Building permits will be required from the
City's Building Department for the private utility portion of the project. Drainage
Sharmin A1-Jaff
March 10, 1999
Page 4
and utility easements shall be dedicated over the public utility lines outside of the
right-of-way on the final plat. Depending on the depth of the utilities, the
minimum drainage and utility easement width shall be 20 feet wide.
STREETS
The developer has petitioned the City to construction the street and utility
improvements for Lake Drive West which is listed as a collector street on the
City's Comprehensive Transportation Plan. Lake Drive West is also a Municipal
State Aid Route. Lake Drive West is proposed to be constructed in accordance
with the City's Urban/Industrial Street Section which is a 9-ton road design, 36-
foot wide face-to-face street section, boulevard street lighting and landscaping.
An 8-foot wide bituminous trail will also be constructed along the northerly right-
of-way line of Lake Drive West. Landscaping under the city's project will be
limited to the city's parkland area.
A preliminary traffic study/investigation was performed in conjunction with the
EAW for the Redmond site plan back in 1990. Staff has required the developer to
update the traffic study to reflect this proposal and determine the full impacts of
the project. According to the preliminary traffic study development of this property
will generate traffic numbers to support the need for a traffic signal at Lake Drive
West and Powers Boulevard. The City's feasibility report for Lake Drive West did
not take into account for a traffic signal along Powers Boulevard (County Road
17). The City and County will have to coordinate the installation of a traffic signal
to accommodate trip generations from the site. It is recommended that the
developer be required to escrow with the City a financial guarantee for a share,
based on traffic generated from the site, of the local cost participation for a traffic
signal at Lake Drive West and Powers Boulevard. The City's local participation
cost of the traffic signal is not known at this time. Preliminary estimates between
the City and County should be used for an security escrow. A condition to address
this issue will be placed in the development contract. Once a final traffic study is
completed to address the traffic related issues as a result of this development, staff
will be able to incorporate a methodology to determine the developer's share for a
future traffic signal. The City has previously required security escrow from the
developers' of the Chanhassen East Business Center and Chanhassen Business
Center for this same scenario.
The City will be constructing Lake Drive West between Audubon Road and
Powers Boulevard. The developer will be dedicating the necessary right-of-way
width (80 feet) along Lake Drive West with the plat. "A" Street is proposed to be
constructed by the developer as part of the overall development improvements.
Boulevard lighting and sidewalk/trail should also be included as street
improvements required along "A" Street. The streets lights should be the City's
Sharmin A1-Jaff
March 10, 1999
Page 5
standard industrial/collector-type street light which is a 25-foot high corten steel
street light. Locations of the street lights will be determined by staff and the
developer at the construction plan review stage. The lights are typically staggered
200 feet apart on both sides of the street.
According to the preliminary plat for Chanhassen Lake Business Park 7th Addition,
"A" Street measures 50-feet wide (right-of-way). The subdivision ordinance
requires a 60-foot wide right of way. The developer will need to amend the plat to
provide for a 60-foot wide right-of-way along "A" Street. The right of way along
Audubon Road is not clearly defined on the preliminary plat. A 50 foot wide right
of way is required. The city has previously acquired easements (trail/right of way)
with past projects along Audubon Road. The final plat shall denote easements of
records and dedicate a 50 foot wide right of way for Audubon Road.
Upon review of the individual driveway access points along Lake Drive West, staff
is generally comfortable with the locations with the exception of Lot 8 onto Lake
Drive West. Since Lake Drive West is a collector road which will carry higher
volumes of traffic, access points should be limited whenever possible. Staff
believes Lot 8 should relocate the access from Lake Drive West to "A" Street.
Staff has also reviewed the access needs from the surrounding parcels. The parcel
immediately to the south and east of the site (Lake Susan Hills Partnership) is
guided for R12 Land Use. Lake Drive West roadway improvement will
adequately serve the needs of that parcel. The individual driveway access points
will be reviewed at time of subdivision. The Cityts park property directly south of
Lake Drive West is proposed to have a parking lot constructed in conjunction with
the City's improvement project for Lake Drive West. The other city parkland,
east of the site, will not have any driveway access. Staff also reviewed the access
needs for the Stockdale parcel which is located west of the site on Audubon Road.
The developer is providing an ingress/egress easement over Lots 2 and 3, Block 1
as a secondary access for the Stockdale parcel through Lot 2, Block 1 out to Lake
Drive West to eliminate the need for additional access points along Audubon
Road. A cross access easement will need to be prepared and recorded by the
developer in favor of the property owner (Stockdale).
"A" Street shall be designed and constructed by the developer in accordance with
the Cityts Standard Specifications and Detail Plates. Detailed construction plans
and specifications for the streets and utilities to be constructed by the developer
will require staff review and City Council approval. The developer will also be
required to enter into a development contract with the City and provide a financial
security in the form a letter of credit or cash escrow to guarantee site
improvements. Preliminary and final plat approval should be contingent upon the
Sharmin A1-Jaff
March 10, 1999
Page 6
City Council ordering and awarding Public Improvement Project No. 98-16 (Lake
Drive West) to service this development. Without the extension of Lake Drive
West and the associated utilities, this development should be considered
premature.
EROSION CONTROL
Erosion control measures are proposed throughout the site. Due to the terrain and
the amount of grading, additional erosion control measures may be necessary.
Staff believes that a temporary sediment and erosion control plan should be
developed which includes temporary sediment ponds, phasing of grading
operations, and restoration be prepared by the developer. Type III erosion control
fence will be required adjacent to the wetland areas. Stormwater ponds and/or
temporary detention ponds shall be constructed with the initial grading phases to
minimum erosion potential to the wetlands or downstream waterbodies. Erosion
control blanket will be required on slopes greater than 3:1. Revegetation of
exposed slopes should occur immediately after grading is completed in accordance
with the City's Best Management Practice Handbook.
RECOMMENDED CONDITIONS OF APPROVAL
The developer shall supply the City with a detailed haul route for review
and approval by staff for materials imported to or exported from the site.
If the material is proposed to be hauled off-site to another location in
Chanhassen, that property owner will be required to obtain an earthwork
permit from the City.
The applicant will need to develop a temporary sediment and erosion
control plan in accordance with the City's Best Management Practice
Handbook. The plan shall be submitted to the City for review and formal
approval in conjunction with final plat submittal.
o
All areas disturbed as a result of construction activities shall be immediately
restored with seed and disc-mulched or wood fiber blanket or sod within
two weeks of completion of each activity in accordance with the City's
Best Management Practice Handbook.
All utility and street improvements shall be constructed in accordance with
the latest edition of the City's Standard Specifications and Detail Plates.
"A" street shall be constructed in accordance with the city's urban
industrial street section. Detailed street and utility plans and specifications
shall be submitted for staff review and City Council approval. All private
streets/driveways shall be constructed to support a minimum of 7-ton per

All driveway access points shall incorporate the City's Industrial Driveway
Apron Detail Plate No. 5207.
The applicant shall provide detailed storm sewer calculations for 10-year
and 100-year storm events and provide ponding calculations for
stormwater quality/quantity ponds in accordance with the City's Surface
Water Management Plan for the City Engineer to review and approve. The
applicant shall provide detailed pre-developed and post-developed
stormwater calculations for 100-year storm events and normal water level
and high water level calculations in existing basins, created basin, and/or
creeks. Individual storm sewer calculations between each catch basin
segment will also be required to determine if sufficient catch basins are
being utilized. In addition, water quality ponding design calculations shall
be based on Walker's Pondnet model.
The applicant shall enter into a development contract with the City and
provide the necessary financial security to guarantee compliance with the
terms of the development contract.
The applicant shall apply for and obtain permits from the appropriate
regulatory agencies, i.e. Carver County, Watershed District, Metropolitan
Waste Control Commission, Health Department, Minnesota Pollution
control Agency, Minnesota Department of Natural Resources, Army Corps
of Engineers and Minnesota Department of Transportation and comply
with their conditions of approval.
The stormwater pond proposed "by others" on the City's parkland located
south of Lake Drive West shall be eliminated and the stormwater rerouted
into the proposed stormwater pond north of Lot 3. The storm pond
proposed east of lot 10 shall be redesigned off the city's parkland and
sanitary sewer line. If the developer desires to leave the pond as proposed
they shall be responsible for the cost of relocating the sanitary sewer line
and pay the city for use of the parkland.
The developer shall be responsible for acquiring temporary construction
easements for construction activities outside the plat.
No berming shall be permitted within the city's right of way. Landscaping
maybe permitted subject to staff review and approval.

6. Description Give a complete description of the proposed project and ancillary facilities (attach additional sheets
as necessary). Emphasize construction and operation meflmds and features that will cause physical manipulation of
the environment or produce wastes. Indicate the timing and duration of construction activities.
The proposed Chanhassen Lakes Business Park 7th Addition project will develop 51.6 acres of land for
10 commercial/warehouse buildings. The project will result in 380,000 square feet of
commercial/warehouse space. Various commercial sites will access the north side of a proposed public
street (Lake Drive West). This new street will connect Audubon Road and C.S.A.H. No. 17.
The business park will be constructed using standard commercial building construction techniques.
Temporary environmental impacts that are related to construction include:
Noise- Noise pollution from construction equipment will be present during
development of the property. The noise pollution will be of a temporary nature and will be
limited to construction hours as set by the City of Chanhassen. Permanent noise pollution is expected
to be below MPCA L-10 daytime standards.
Dust- Depending of climatic conditions during construction dust may be considered a nuisance.
Dust control measures will be taken as required by the city.
Erosion/Runoff- During construction Best Management Practices(BMP's) as outlined by the MPCA
standards and NPDES permit will be utilized to minimize any impacts associated with site erosion and
runoff.
All solid waste materials produced during construction will be processed and disposed of in accordance
with local, state and federal requirements. At full development the project waste will be disposed
of by private haulers at permitted facilities in accordance with all applicable local, state and federal
regulations.
The project proposes to fill 1.28 acres of Type 2 an 3 wetland for construction. These impacts will be
mitigated with a combination of 1.62 acres of new Type 3 wetland and public value credits (stormwater
ponds, buffer strips).
Construction of Lake Drive West, "A" Street and extension of utilities will begin in June or July of
this year. Individual building site development will begin later this year. It is expected to take
several years to complete individual building sites. Street construction and utility construction will be
completed by fall assuming authorization for construction(Lake Drive) by the City of Chanhassen.
Note: An EAW for this property was prepared in 1990. This EAW was for a proposed 439,690 square
foot Redmond Products office, production and warehouse facility. As part of that EAW the following
studies were completed: Geotechnical Explorafion(GME Consultants 1989), Phase 1 Environmental
Assessment(Llesch Associates, 1989) and Traffic Study(Westwood, 1990). The proposed facility is
smaller than the proposed 1990 Redmond facilityand is not of a production nature. For this reason,
many of the conclusions in this EAW are based on data from the studies completed for the 1990 EAW.
Copies of the above individual studies previously completed for the Redmond proposal can be obtained
from the City of Chanhassen upon request.

11. Fish, Wildlife, and Ecologically Sensitive Resources
a. Describe fish and wildlife resources on or near the site and discuss how they would be affected by the
project. Describe any measures to be taken to minimize or avoid adverse impacts.
The project site contains minimal wildlife habitat due to long-term grazing activity. The
wetlands on this site have been classified by the City of Chanhassen as "Ag/Urban". This
wetland was historically drained, but a dralntile break has restored the open water habitat.
There are no environmentally sensitive areas on the property.
b. Are there any state-listed endangered, threatened, or special-concern species; rare plant communities;
colonial waterbird nesting colonies; native prairie or other rare habitat; or other sensitive ecological
resources on or near the site?
<> Yes <X> No
A preliminary database check with the U.S. Fish and Wildlife department does not indicate any
endangered, threatened, or special concern species;rare plant communities; colonial waterbird
nesting colonies; native prairie or other rare habitat; or other sensitive ecological resources are on or
near the site.
If yes, describe the resource and how it would be affected by the project. Indicate ifa site survey of
the resources was conducted. Describe measures to be taken to minimize or avoid adverse impacts.
12. Physical Impacts on Water Resources Will the project involve the physical or hydrologic alteration (dredging,
filling, stream diversion, ouffall structure, diking, impoundment) of any surface Water (lake, pond, wetland, stream,
drainage ditch)? <X> Yes ~ No
If yes, identify the water resource to be affected and describe: the alteration, including the
construction process; volumes of dredged or fill material; area affected; length of stream divemon; water
surface area affected; timing and extent of fluctuations in water surface elevations; spoils disposal sites; and
proposed mitigation measures to minimiTe impacts.
Historically the large wetland on the site was drained and partially farmed. A drainfile break
has resulted in the restoration of open water habitat in this wetland. At this time the only
wetland exemption to the Minnesota Wetland Conservation Act proposed for this project is
the Deminimis Exemption.
Approximately 1.28 acres of Type 2 and 3 wetland will be impacted by this project. These
areas will be mitigated in accordance with the Minnesota Wetland Conservation Act(MWCA).
Mitigation will result in the creation of 1.62 acres of new Type 3 wetland. The existing
PUB/EMF basin will be expanded. The major impacts will occur in two smaller agriculturally
degraded wetlands. All wetlands on this property have a City of Chanhassen classification of
"Ag/Urban".
The wetland boundary of the large Type 3/4 wetland basin at the center of the project is
currently being evaluated based on drainage activities and previous delineation information.
The actual size of this wetland is yet undetermined. Until this determination is complete exact
mitigation numbers will not be available. The City of Chanhassen will complete a sequencing
report in accordance with the MWCA to determine whether the impacts can be eliminated or
are a necessary part of the project plat process. A review of the proposed impacts has not been
completed at this time.
The above proposed activities will require a City of Chanhassen permit(GP-17 Status) and
must meet MWCA requirements.
13. Water Use
a. Will the project involve the installation or abandonment of any wells? ~ Yes <X> No
For abandoned wells give the location and Unique well number. For new wells, or other previously
unpermitted wells, give the location and purpose of the well and the Unique well number (if known).
b. Will the project require an appropriation of ground or surface water (including dewatering)?
If yes, indicate the source, quantity, duration, purpose of the appropriation, and Minnesota
Depamnent of Natural Resources (DNR) water appropriation permit number of any existing
appropriation. Discuss the impact of the appropriation on ground water levels.
c. Will the project require connection to a public water supply?
<X> Yes ~ No
If yes, identify the supply, the DNR water appropriation permit number of the supply, and the quantity to be
used.
The project will be connected to the City of Chanhassen water supply system. The fully
developed and utilized daily wateruse is estimated to be 18,900 gallons.
14. Water-related Land Use Management Districts Does any part of the project site involve a shoreland zoning
district, a delineated 100-year flood plain; or a state or federally designated wild or scenic river land use
district? <> Yes <X> No
If yes, identify rite district and discuss the compatibility of the project with the land use restrictions of the
district.
15. Water Surface Use Will the project change the number or type of watercraft on any water body?
oyes <X> No
If yes, indicate the current and projected watercraft usage and discuss any potential overcrowding or conflicts
with other users or fish and wildlife resources.
16. Soils Approximam depth (in fee0 to:
Ground water: minimum 10' average 20'

Describe any steep slopes or highly erodible soils and identify them on the site map.
See Figure 4a(Existing Conditions)
Describe the erosion and sedimentation measures to be used during and after construction of the project.
BMP's will be utilized in accordance with City of Chanhassen, MPCA and watershed district
requirements. These BMP's will include silt fence, grading techniques, sediment filters and
revegitation schedules.
18. Water Quality-Surface Water Runoff
a. Compare the quantity and quality of site nmoff before and after the project. Describe methods to be used
to manage and/or treat nmoff.
The proposed project must meet aH watershed and city requirements for water quality. Developed
hard surface areas must be routed through treatment ponds that meet NURP design standards prior
to discharge into receiving waters. Developed peak discharge rates for the critical duration 2, 10 and
100 year storm events must be less than or equal to existing peak discharge rates.
The proposed project will have three stormwater basins designed to meet NURP standards. These
basins will treat stormwater prior to discharge into existing wetlands.
Water Quality:
NURP ponds will be constructed to treat hard surface runoff prior to discharge into existing wetlands.

The estimated pollutant levels were determined by using the MPCA BMP's manual Table 2-1 "Mean
Pollutant Concentration" for open and commercial uses. Because the proposed commercial areas will
be routed through proposed NURP ponds, the commercial runoff pollutant levels will be reduced.
The ranges were established using the Walker Method "Typical Wet Detention Pond Performance"
table. As this site does not discharge directly into a lake or protected water a nutrient balance was not
completed.
Based on utilization of NURP ponds it is expected that no increase in pollutant concentrations is will
occur for this site.

Water Quantity:
The proposed drainage will leave the site at two locations. The existing large wetland will receive
treated and detained runoff from the NURP Basins 1 and 2 and outlet into the Chicago, Milwaukee,
St. Paul and Pacific Railroad right of way. Due to large storage volumes available in the existing
wetland and proposed NURP basins, the outflow to the Railroad is nominal and therefore an estimate
of existing conditions runoff was not made. Proposed NURP Basin 3 will outlet into Riley Creek. An
existing conditions analysis was performed to determine the allowable outflow rates to Riley Creek
from Basin 3. Attached Figures 4F and 4G show the existing and proposed drainage areas.

from Basin 3. Attached Figures 4F and 4G show the existing and proposed drainage areas.
19. Water Quality-Wastewaters
a. Describe sources, quantities, and composition (except for normal domestic sewage) of all sanitary and
industrial wastewaters produced or treated at the site.
No industrial type water will be discharged. The wastewater will be limited to domestic type wastes.
Some washwater from the warehouses with cleaning solutions will also be discharged. W~en fully
developed and utilized the site is expected to produce approximately 0.077 MGD of wastewater.
b. Describe any waste treatment methods to be used and give estimates of composition after treatment, or if
the project involves on-site sewage systems, discuss the suitability of the site conditions for such systems.
Identify receiving waters (including ground water) and estimate the impact of the dischaxge on the quality
of the receiving waters. (If the discharge may affect a lake consult "EAW Guidelines" about whether a
nutrient budget analysis is needed.)
None(Subsurface information indicates that the existing wetlands are perched and not connected to
the water bearing aquifers in the area.
c. If wastes will be discharged into a sewer system or pretreatment system, identify the system and discuss
the ability of the system to accept the volume and composition of the wastes. Identify any improvements
which will be necessary.
All wastewaters will be discharged into the city wastewater system. These wastewaters will flow to the
Met Council interceptor and to the Blue Lake treatment plant. No need for special pretreatment of
wastewater at the site is anticipated. Existing facilities have the capacity to handle the ultimate flow
from this property.

plan approval if required.
b. Indicate the number, location, size, and use of any above or below ground tanks to be used for storage of
petroleum products or other materials (except water).
None anticipated
22. Traffic Parring spaces added *see Parking below Existing spaces (if project involves expansion) <>
Estimated total Average Daily Traffic (ADT) generated 2,340 trips(at full development) Estimated maximum peak
hour traffic generated (if known) and its timing: 269 trips, PM peak hour 4:30 to 5:30(at full development), <>.
For each affected road indicate the ADT and the directional distribution of traffic with and without the project.
Provide an estimate of the impact on traffic congestion on the affected roads and describe any traffic improvements
which will be necessary.
Parking:
The developer will revise the site plan to show the actual number of parking spots being proposed.
This number is expected to be in the range of 500 parking spots. The preliminary drawings used for
construction plans do not accurately depict the number of actual parking spaces that will be
constructed.
Traffic:
An updated preliminary traffic study has been completed that compares the proposed 1990 facility for
which complete traffic study was completed for to the proposed facility. The study indicates the
following:
The proposed development will generate approximately 108 more trips during the PM peak hour than
the 1990 project. Based on the directional distribution used in the 1990 study approximately 44
10
more trips directed to and from Audubon Road and 64 more trips directed to and from CSAH 17 at
full development will be generated by the proposed project.
The proposed development will generate approximately 515 more trip ends than the 1990 proposal on
an average weekday. This will result in 211 more trips to and from Audubon Road and 304 more trips
,~-~-~d~'t~nd r'~o~ CS~ 17 during a typical weekday.
A
The City is currently comparing the 1999 preliminary study with the existing 1990 study for this site
to determine whether the traffic recommendations of the 1990 report are valid for this project. If it is
determined that the recommendations are not sufficient for this project a new comprehensive traffic
study will be required.
23. Vehicle-related air emissions Provide an estimate of the effect of the project's traffic generation on air quality,
includiag carbon monoxide levels. Discuss the effect of traffic improvements or other mitigation measures on air
quality impacts. (If the project involves 500 or more parking spaces, consult "EAW Guidelines" about whether a
dotailed air quality analysis is needed.)
The City will review the revised site plan for proposed parking spaces and may require an air quality
analysis prior to approval of the EAW.
24. Stationary source air emissions Will the project involve any stationary sources of air emissions (such as boilers
or exhaust stacks)?
~ Yes <X> No
If yes, describe the sources, quantifies, and composition of the
emissions; the proposed air pollution control devices; the quantifies and composition of the emissions after

into an office/warehouse development(Chanhassen Business Center).
d. If a, b, or c were marked Yes, discuss any cumulative environmental impacts res~flting from this project
and the other development.
Any development on adjacent parcels will be limited based on the natural topography. For these
reasons the future development is expected to be minor and no negative cumulative impacts are
anticipated.
31. Other Potential Environmental Impacts If the project may cause adverse environmental impacts which were not
addressed by items 1 to 28, identify and discuss them here, along with any proposed mitigation.
32. SUMMARY OF ISSUES (This section need not be completed if the EAW is being done for EIS scoping;
instead, address relevant issues in the draft Scoping Decision document which must accompany the EAW.) List any
impacts and issues identified above that may require further investigation before the project is commenced. Discuss
any alternatives or mitigative measures that have been or may be considered for these impacts and issues, including
those that have been or may be ordered as permit conditions.
The submitted plans are preliminary and a sequencing report for the proposed wetland impacts has
not been completed. The proposed impacts may not be permitted by the MWCA. The City of
Chanhassen may make modifications to the plans to minimize these impacts and it is anticipated that
all potential concerns related to the wetland impacts can be addressed as part of the preliminary plat
process.
Based on the previous EAW and associated studies completed for this project it is not anticipated that
any negative environmental impacts will result from this project.
The proposed project does not pose any environmental impacts to the surrounding area and is in
compliance with City of Chanhassen comprehensive plans. None of the above discussed issues indicate
that any further environmental review is needed.

EXHIBIT A
~ONCLUSIONS AN~RECOMMENDATIONS
The proposed Redmond facility will operate (shift changes, delivery
times, etc.) such that its peak hour of traffic operations does not
coincide with the peak hour of the overall surrounding roadway system.
In 1992, one year after Phase 1 occupancy the following p.m. peak hour
roadway operations are projected:
Level of Service
Signalized Intersection of TH 5/CSAH 17
Unsignalized Intersection of TH 5/Audubon Road, or
Signalized Intersection of TH 5/Audubon Road
Unsignalized Intersection of Lake Drive West/CSAH 17
Unsignalized Intersection of Lake Drive West/Audubon
B

D
A
In 2000, one year after final buildout the following p.m. peak hour
roadway operations are projected:
Level of Service
Signalized Intersection of TH 5/CSAH 17 C
Signalized Intersection of TH 5/Audubon Road B
Unsignalized Intersection of Lake Drive West/CSAH 17 E/F
Unsignalized Intersection of Lake Drive West/Audubon - C
To best accommodate traffic operations into and out of Lake' Drive West
the following geometric features are recommended:
CSAH 17 at Lake Drive West: Right and left turn lanes for Lake
Drive~ explore possibility of southbound right turn lane and
northbound bypass land on CSAH 17.
Audubon Road at Lake Drive West: Construction of City's planned
44' roadway on Audubon and 36' roadway on lake Drive West will
accommodate traffic.
TH 5 at CSAH 17: Mn/DOT plans for upgrading of TH 5 will provide
efficient, high capacity operations.
TH 5 at Audubon Road: A traffic signal will likely be warranted
and justified at this intersection by 1992. Because a signal will
be warranted, and Mn/DOT has not yet committed to widening TH 5
west of CSAH 17, (no time table exists for the widening) a
likely scenario is that a temporary signal would be recommended
for initial operations. The signal would then be replaced with a
permanent signal when TH 5 is widened to four lanes in this area.
The proposed 36' roadway section along Lake Drive West will adequately
serve immediate site access needs. Due to the low volumes and slow
speeds along Lake Drive, turn lanes into site driveways will not be
required.
Between today and the year 2010 this entire area will experience large
growth in traffic volumes. The need for some of the improvements
mentioned in this study which are off in the future, (i.e. possible
signalization of Lake Drive West and CSAH 17), should be monitored.
Thereby the proper staging of roadway system modifications can be made
as the needs and warrants for these improvements are met.

Trip Generation Review for Chanhaasen Lakes Business Park 7~ Addition
PURPOSE
This is to present the results of our ~p generation review/'or your proposed office/warehouse
development in Chanhassen. The results are ~e~, ted as a comparison of trips generate! by
your current proposed developm, e, nt as related to trips that would have been 8enerated by the
prior development plsrmed for this property. $ .~cio. nt d_ata on ,the prior and proposed
developments was available for two time periods. Therefore, mp generation was examinea
during the PM peak hour (about 4:30 to 5:$0pm) and. during sn avora$? w.~. y~._ Not ~ough
information ,was available to enable us to compare trip generation resu}.ts dunng~b AM peak
hour comparison. "~"
PRIOR DEVELOPMENT
Information about the prior development was obtained from a document prepared by West'wood
Professional Services, Inc. titled Traffic Study for R~_4mon, d Products. Inc. N~v ~a~iliib, in
Chanh~issen. Minnesota. This report was produced in Apnl of 1990. The pn'or dev,.o!opment
consisted ora total of 469,690 square feat in one main building and one smaller braiding. The
main building was expected to be d. ivided into general office (54,000 square ,f?), warehousing
(I62,665 square feet), and production (221,025 square feet), The smaller building would have
contained a daycare facility (2,000 square feat).
Trip generation for the PM peak hour was based upon em, ploye~ trips recorded at the company's
existing facility. To account for an increase in building s~ze, a ratio of future employees
compared to current emp, loyees was applied to the trips. There was not a daycare £aoility at tho
existing bull,ding and so it was not accounted for in those trip generations. Therefore, a PM peak
hour generation rate for a dayesre facility, pub, lished by the Institute of Transportation Engineers
(ITE), was used to determine the number o/'tnps gener~t....ed by that use. The remlting trips were
then added to the trips generated by the Redmond's' facility to detmnine a final number. The
result is that the prior planned development would have generated a total of about 161 trip ends
during the PM peak hour. This number is quite iow considering the size of the development. A
principal reason for this outcome is that Redmond's has an employee $hiR change in their
production facility that occurs before the PM peak hour.
Mr. Mark Undestad -2-
February 9_6, 1999
The daily trip seneratlon was based upon 1TE daily rates for a daycarc facility and for a
manufacturing plant (which accounts for the other three uses). On .th/.s basis, we have estimated
that the prior development would have generated about 1,830 da/ly mp ends.
~NT PROPOSED DEVELOPMENT
From information provided by yo,~ the proposed development, .consists ora total of 380,000
aquarc fcct divided amons ten buddings. Thc two uses compnsm8 thc development arc Scncral
office with 76,000 square feet and warehousing with 304,000 square fe~.
We have estimated the trip generati ,on for the proposed development by using trip generation
rates published by ITE. On this baszs, we have determined that the proposed development would
generate about 269 trip ends during the PM peak hour and 2,345 ~p ends on a daily basis.
CONCLUSIONS
Comparing the trips generated for the PM peak hour, the proposed development would generate
approximately 108 more trip ends than the prior development. B. ase.d, upon the directional
distribution used in the 1990 traffic, study, this means 44 more trips dzrected to and from
Audubon Road and 64 more trips dtrected to and from CSAH 17.
Comparing the trips generated during an average weekday, the proposed development would
gener.at? approximately 515 more trip ends than the prior development. This would result in 211
more trips to and from Audubon Ro~ and 304 more trips directed to and from CSAH 17 during
a typical weekday.
L~t us know it'you have any questions about the items addressed in this memorandum.

Dear Mr. AI-Jaff:
Council staff has reviewed the environmental assessment worksheet (EAW) for the
Chanhassen Lakes Business Park - 7th Addition to determine its adequacy and accuracy in
addressing regional concerns.
This EAW proposes to construct a 439,690 square foot office, production and warehouse facility.
The staff review has concluded that the EAW is complete and accurate with respect to regional
concerns and raises no major issues of consistency with Council policies. An EIS is not necessary
for regional purposes. Staff submits the following advisory comments:
Item No 19. Water Qua/ity- Wastewaters (Don Bluhm, 651-602-1116)
The MCES has its interceptor 8253-328 located on the eastern part of the proposed development. It
will be necessary to provide detailed grading plans to the MCES for approval before any work is
done over our interceptor easement.
This will conclude the Council's review of the EAW. No formal action on the EAW will be taken
by the Council. If you have any questions or need further information with respect to these

Environmental Assessment Worksheet (EAW)
Dear Ms. AI-Jaff:
The Department of Natural Resources (DNR) has reviewed the EAW for the Chanhassen Lakes
Business Park 7~h Addition Project. We offer the following comments for consideration.
Item 14, Water Related Land Use Management Districts, should be answered "yes" because a portion
of the eastern side of the site is within 300 feet of Riley Creek. Activity within 300 feet of Riley Creek
falls within the designated Shoreland Management District. All City shoreland management
requirements need to be met, with particular emphasis on review of the proposed activities in the
"shore impact zone" and the amount of impervious surface.
In addition, Item 14 should recognize that the project could result in floodplain impacts. The proposed
treatment basin located nearest to Riley Creek will require activity that lies within the floodplain shown
on the City's official FEMA maps. Although the specifics are difficult to discern on the figures
provided, it appears that grading for the treatment pond includes filling in the floodway portion of the
Riley Creek floodplain. Filling in the floodway is generally discouraged and cannot be allowed without
going through a conditional use permit (CUP) process and demonstrating that the filling will not "cause
any increase in the stage of the 100-year or regional flood, or cause an increase in flood damages in the
reach or reaches affected, (in accordance with City of Chanhassen regulations; Section 20-367).
Thank you for the opportunity to review this project. We do not recommend the preparation of an
environmental impact statement (EIS) for the project based upon natural resource considerations. We
look forward to receiving your record of decision and responses to comments. Minnesota Rules part

Traffic Update for Chanhassen Lakes Business Park 7th Addition
PURPOSE
This is to present the results of our traffic update for your proposed office/warehouse development
in Chanhassen. The proposed development will be located to the south of TH 5 between CSAH 17
on the east and Audubon Road on the west. Lake Drive West will be constructed from its current
intersection at Audubon Road east to CSAH 17. This new section of Lake Drive West will
become the site's southern border, and the Chicago, Milwaukee, St. Paul, & Pacific Railroad
constitutes the northern border. Figure 1 shows the location of the proposed development.
This traffic update builds upon the trip generation work we previously completed and provides an
overall update to the prior traffic study completed in 1990. The analysis focuses on the operation
of the following four key intersections around the proposed site during the PM peak hour:
TH 5/CSAH 17 (existing intersection)
· TH 5/Audubon Road (existing intersection)
· Lake Drive West/Audubon Road (existing "T" and future four-way intersection)
· Lake Drive West/CSAH 17 (future intersection)
In addition to the PM Peak Hour, the average daily traffic (ADT) on the surrounding roadways is
also examined.

SITE LOCATION
Mr. Mark Undestad -3- March 29, 1999
BACKGROUND
Existing Conditions
The proposed site is undeveloped today, and only three of the four intersections currently exist.
The Lake Drive West extension is expected to be built in conjunction with this development.
The intersection of TH 5 and CSAH 17 is a four-way intersection controlled by a traffic signal.
The east and west approaches on TH 5 consists of one left turn lane, two through lanes, and one
channelized right turn lane. The north approach on CSAH 17 provides two left turn lanes, two
through lanes, and one channelized right turn lane. The south approach on CSAH 17 consists of
one left turn lane, two through lanes, and one channelized right turn lane. The traffic signal has
actuated eight phase control offering protected only left turn phases on all approaches.
The intersection of TH 5 and Audubon Road is a four-way intersection with the northern leg
servicing a private drive. The intersection is controlled with stop signs on Audubon Road and the
private drive to the north. The west approach on TH 5 consists of one lane for all movements
while the east approach provides one primary lane for movements with a bypass lane that also acts
as a right turn lane into the private drive to the north. Audubon Road and the private drive both
consist of one lane for all movements. However, the south approach on Audubon Road is wide
enough to allow traffic to divide into one left turn/through lane and one right turn lane. This
condition generally occurs when a number of vehicles arrive at the approach at the same time.
The intersection of West Lake Drive and Audubon Road is currently a "T" intersection with no
access provided to the east. The north and south approaches on Audubon Road consists of one
lane for all movements. The west approach on West Lake Drive also provides one lane for all
movements.
No intersection currently exists at proposed location of the West Lake Drive/CSAH 17
intersection. CSAH 17 has one lane of travel in each direction at the proposed intersection
location.
Proposed Characteristics
The proposed development will consists of a total of 380,000 square feet divided among ten
buildings. The two uses comprising the development are general office with 76,000 square feet
and warehousing with 304,000 square feet. In conjunction with this development, Lake Drive
West will be extended east beyond Audubon Road to CSAH 17. The neTM section of Lake Drive
West and the proposed development will be completed in the fall of 2000.
The extension of Lake Drive West will alter the "T" intersection with Audubon to a four-way
intersection with stop sign control on Lake Drive West. The new east approach on Lake Drive
West is planned to provide one lane for all movements. No changes are expected at the other
intersection approaches.
Mr. Mark Undestad -4- March 29, 1999
The Lake Drive West extension will also create a new "T" intersection at the connection with
CSAH 17. This intersection is expected to be approximately 1000 feet south of the intersection of
Lake Drive East and CSAH 17. The east approach on Lake Drive West will consists of one lane
for all movements and will have stop sign control. CSAH 17 will remain a two lane roadway with
one lane for all movements in each direction.
No changes are expected for the other two intersections at TH 5/CSAH 17 and TH 5/Audubon
Road. No other new developments have recently been approved.
TRAFFIC FORECASTS
Trip Generaion
Trip generation for the proposed development was developed and presented in a memorandum
dated February 26, 1999. Generation was developed using trip generation rates furnished by the
Institute of Transportation Engineers (ITE). On that basis, the proposed development is projected
to generated about 269 trip ends during the P.M. peak hour and 2,345 trip ends on a daily basis.
Traffic Distribution
Distribution of the traffic generated by the proposed development was based upon the trip
distribution used in the 1990 traffic study. From that study, percentages for five major approaches
were developed. The table below summarizes the percentages used for the site direction of
approach.
APPROACH DIRECTION
TH 5 from the east
TH 5 from the west

Traffic Volumes
The PM peak hour traffic volumes for the key intersections were developed for three scenarios;
the 1999 existing, the 2001 no build, and the 2001 post-development. The developer estimates
that the proposed development and new section of road will be completed and occupied by late
2000. Therefore, the year 2001 has been selected as the analysis year for this study, representing
the first full year after completion. The first 2001 scenario repre, sents growth of traffic without this
specific development. Traffic increases were projected using the City of Chanhassen's 20-year
growth factor. Based on that growth factor, the traffic is estimated to increase about 2.5% per year
or about 5% in two years. It is assumed that the extension of Lake Drive West would not be built
in this scenario. The next 2001 scenario adds in the proposed development traffic. All scenarios
are based on turn movement counts collected at the intersections of T.H. 5/Audubon Road and

T.H. 5/C.S.A.H. 17 on March 18, 1999. Figure 2 shows the volumes estimated at the four key
intersections for all three scenarios during the PM peak hour.
In addition to the PM peak hour, the average daily traffic (ADT) was examined. The ADT was
developed for seven locations based upon the 1996 Average Annual Daily Traffic (AADT) for the
seven county area. The table below summarizes the ADT for the following three scenarios; 1999
existing, the 2001 no build, and the 2001 full development.

TRAFFIC ANALYSIS
The four key intersections were analyzed to determine the effect of the proposed development on
traffic operations. In order to better understand how each intersection operates from an overall
traffic capacity standpoint, a capacity analysis was performed using the methodology presented in
the Highway Capacity Manual. A capacity analysis is a way to determine how well or poorly an
intersection is operating. Capacity analysis results are presented in terms of level of service,
which ranges from A to F. Level of service A represents the best intersection operation, with very
little delay for each vehicle using the intersection. Level of service F represents the worst
intersection operation, with excessive delay and large queue lengths~.?or most agencies in the
Twin Cities area, level of service D represents the minimal acceptable level of service for regular
daily operations. Measures to alleviate congestion are initiated when intersections experience
level of service E or F conditions '~'?
TH 5 and CSAH 17 Intersection
Using the existing geometrics, signal timing, and volumes, this intersection operates at a level of
service C during the PM peak hour. For the 2001 no build scenario volumes using the current
geometrics and signal timing, the level of service for the intersection is D. For the 2001 post-
development scenario volumes with current geometrics and signal timing, the intersection remains
at a level of service D. This intersection is expected to operate adequately under all scenarios
without changes to the current characteristics.
TH 5 and Audubon Road Intersection
Under the current conditions with existing volumes, the left tums from Audubon Road and the
private drive onto TH 5 are at a level of service F. This condition worsens in the 2001 no build
and the 2001 post-development scenarios. After determination of the level of service F, the traffic
volumes for all three scenarios were compared to the peak hour signal warrant volume thresholds.
The Peak hour signal warrant compares the major street and minor street volumes with a set
volume level, which is based on the number of approach lanes provided. If the volume level is
met, a traffic signal may be considered for the intersection. In this case, the volumes from all
three scenarios meet the traffic signal warrants, thus, a traffic signal may be considered for the
intersection.
Using traffic signal control with the existing geometrics and volumes, the intersection would
operate at a level of service C during the weekday PM peak hour. The 2001 no build and the
post-development PM peak hour volumes are expected to remain at a level of service C.
In addition to consideration ora traffic signal, an upgrade of the geometfics should be
examined. One option is to widen TH 5 to a four lane road with turning lanes at this
intersection. This would increase the capacity and safety of the intersection.
Mr. Mark Undestad -8- March 29, 1999
Lake Drive West Intersection and Audubon Road
Under current conditions, all movements operate at a level of service B or better during the PM
peak hour. The level of service B continues for the 2001 no build scenario. For the 2001 post-
development scenario as a four-way intersection, all movements operate at a level of service C or
better.
Even with an acceptable level of service, we suggest adding a right turn lane for the east approach
on Lake Drive West. This would only involve an additional six feet of roadway on the north side
of the east approach creating two 12-foot westbound lanes and one 18-foot eastbound lane. This
option allows right turns onto Audubon Road to operate without experiencing any delay from left
turn or through vehicles, as well as adding capacity to the approach for future growth.
Lake Drive West Intersection and CSAH 17
This intersection does not exist until the 2001 post-development scenario. With one lane for all
movements in each direction, the intersection has a level of service F for the eastbound approach.
As mentioned above, adding six feet to the west approach allows for two lanes, one right turn lane
and one left turn lane. With these two lanes, the level of service increases to E for the eastbound
approach.
As done previously, the traffic volumes were compared to the peak hour signal warrant volume
thresholds volumes. In this case, the traffic signal warrant is not met. This intersection should be
monitored closely to determine if a traffic signal might be needed in the future.
CONCLUSIONS
Based upon the analyses presented in this report, we have developed the following conclusions:
The proposed development is estimated to generate 56 entering and 213 exiting trips during
the weekday PM peak hour. The average daily traffic (ADT) generated is projected to be
2,345 trip ends.
The TH 5/CSAH 17 intersection is expected to operate at a level of service D for the 2001
post-development scenario and can adequately accommodate the additional volume generated
by the proposed development.
The TH 5/Audubon Road intersection currently operates at a level of service F for the left
turns on the north and south approaches. This condition worsens 'in the 2001 scenarios. Since
sufficient pavement width is available, the south approach should be striped as two lanes, one
lef~ turn/through lane and one right turn lane. This allows right turns to proceed without the
delay experienced by left turn and through vehicles.
· The volumes at the TH 5/Audubon Road intersection meet the traffic signal warrant, and thus,
a traffic signal may be considered for this intersection. Under signal control, the intersection
Mr. Mark Undestad -9- March 29, 1999
operates at a level of service C for all scenarios. The warrant is met with 1999 existing
volumes and should be considered with or without the proposed development. Along with
traffic signal consideration, upgrading the geometrics on TH 5 through the intersection also
should be examined.
The Lake Drive West/Audubon Road intersection, with one lane in each direction for all
movements, can adequately accommodate the traffic generated by the proposed development
with all movements operating at a level of service B or better. We would still suggest
providing two lanes for the east approach by adding six feet to the north side of that approach.
This would provide one 12-foot right turn lane and one 12-foot left turn/through lane. This
option would allows right turns to proceed without delays that may be experienced by the left
turn or through vehicles and increases the capacity of the intersection for future growth.
The Lake Drive West/CSAH 17 intersection has a level of service F for the eastbound
approach with each approach providing one lane for all movements. By adding six additional
feet of roadway to the west approach, the approach can be striped as one right turn lane and
one left turn lane. Under this condition, operations on the east approach improve to a level of
service E.
