subdivision of Outlot F will be subject to all city ordinances in effect.
FINAL PLAT
PROPOSAL SUMMARY
The applicant is proposing a 48 lot subdivision with five outlots on 39.5 acres.
Approximately 5.7 acres of the site, shown as Outlots A and D, are existing wetlands.
Drainage and utility easements will be dedicated over Outlots A and D, but ownership is
proposed to remain private. A public trail of 2.78 acres will be dedicated as Outlot B along
the Bluff Creek corridor. Outlot C is a proposed stormwater ponding area to be dedicated to
the city. Outlot E, in the northwest corner of the site, is a remnant piece that is
undevelopable and is used to provide an acceptable grade to the creek. Outlot E may be used
to locate an entrance monument for the site or it could be assembled with Lot 1, Block 3.
Four of the proposed lots, Lots 8, 9, 10, and 11, Block 2, were not approved as part of the
preliminary plat. The city will purchase this land as part of the city's park and open space
system. As a condition of approval, the applicant is to show this area as an outlot on the
final plat. Since the city and applicant could not agree on an acceptable price for this land,
the city is proceeding with the condemnation of this property.
As part of the preliminary plat, the city approved a conditional use permit for alterations
within the flood plain and a wetland alteration permit. Those approvals were given based on
the following conditions which still apply.
Conditional Use Permit
The City Council approved Conditional Use Permit #94 -4 to permit the placement of fill and
excavations and alterations within the flood plain subject to the following condition:
Creekside Addition Final Plat and Rezoning Second Reading
May 3, 1995
Page 14
The applicant shall comply with the wetland fill /excavation and wetland mitigation
conditions as stated in Corps of Engineers Section 404 permit. Mitigation work shall
be implemented prior to or concurrent with wetland fill activity in future phases of the
project. All mitigation work shall be limited to the Bluff Creek corridor and not in
the wetland located at the southwest corner of the site.
Wetland Alteration Permit
The City Council approved Wetland Alteration Permit #94 -4 to permit filling and replacing
wetlands on the site subject to the following conditions:
1. All buffer areas shall be surveyed and staked by the applicant in accordance with the
City's wetland ordinance. The City will install wetland buffer edge signs before
construction begins and will charge the applicant $20 per sign.
2. Wetland buffer areas are required around the wetlands in accordance with the City
Wetland Ordinance. The applicant shall revise the development plans to include a 50-
foot buffer around Bluff Creek with a 100 foot building setback and a 10 to 30 foot
buffer with a minimum average of 20 feet around the tributary to Bluff Creek with a
50 foot building setback.
Staff is recommending that the City Council approve the rezoning of this property to RSF as
well as final plat approval for 44 lots subject to the conditions of this staff report. The
subdivision complies with all requirements of the RSF district regulations.
LANDSCAPING /TREE PRESERVATION
The applicant has provided a tree preservation/landscaping plan for the project that exceeds
minimum code requirements. The applicant has evaluated the tree preservation plan based on
the platting of Lots 8 - 11, Block 2, which the city proposes to acquire for parkland. This
plan requires a minimum of 180 eighty trees be planted, but it provides a total of 189 trees.
The applicant has also evaluated the tree preservation requirements based on the city taking
the 2.46 acres of forested upland. In this instance, a total of 169 trees are required. The tree
preservation/landscaping plan being submitted would adequately address this alternative.
The Creekside Subdivision narrative: Tree Preservation and Landscaping Plan is the
woodland management plan required for this development. This plan addresses the
requirements of a woodland management plan. As a condition of plat approval, the developer
shall provide copies of this plan to the home builders and /or home purchases.

WETLANDS
The wetlands issues have been addressed and the applicant meets the required buffer strips,
setbacks, and wetland mitigation for this phase of the project. The buffer edge
monumentation will be installed after the infrastructure is installed. Type III erosion control
is required around the creek and the wetlands including the ponding areas adjacent to the
wetlands. Future wetland impacts will be addressed with the next phase of the project. The
City is encouraging the developer to restore the wetland as part of their mitigation.
GRADING & DRAINAGE
The final grading plans have been developed to maintain the neighborhood drainage pattern
from Timberwood Estates. The lots adjacent to Timberwood Estates will be graded to match
existing grades at the plat boundary. Stormwater runoff from Timberwood Estates will
continue to drain through Creekside Addition as it has in the past. In addition, the storm
sewer pipe has been extended along Lots 16 and 17, Block 3 to convey runoff from a low
area in Timberwood Estates. The storm sewer has also been sized in accordance to the City's
SWMP to provide future service to Timberwood Estates.
The wooded lots in the southerly portion of the site (Lots 21, 23, 24, 25, 26, Block 3) and the
parkland which is platted as Lots 8 though 11, Block 2 are proposed to be custom graded at
time of building to minimize grading and tree loss. Staff recommends that a detailed grading,
drainage, tree removal, and erosion control plans be submitted with the building permit
application for review and approval by the City prior to issuance of the building permit for
the lot.
The applicant has employed the use of retaining walls along the street adjacent to the wetland
on Outlot D to minimize impacts to the wetland. A guardrail has also been added for safety
purposes. Retaining walls have also been used at the creek crossing in an attempt to preserve
a couple of significant trees.
Wetland buffer areas are shown on the grading plan adjacent to the wetlands. The buffer
strips range between 0 and 20 feet and average 10 feet wide in accordance with the city
ordinance. The plans propose a storm sewer system designed in accordance with the City's
SWMP to convey stormwater runoff to two proposed stormwater ponds for pretreatment prior
to discharging into the wetlands. The applicant has received credits against their SWMP fees
for providing oversized ponds and storm sewers in accordance to SWMP methodologies.
Staff has calculated the applicant's SWMP water quantity connection fee at $29,590. This fee
will be payable prior to the City signing the final plat.
The applicant and staff have met with the Riley- Purgatory -Bluff Creek Watershed District
engineering to resolve a discrepancy with the high water level of the Bluff Creek flood plain.
Creekside Addition Final Plat and Rezoning Second Reading
May 3, 1995
Page 16
The grading and development plans have been designed taking into account the agreed upon
flood plain level to maintain a 3 -foot grade separation between the lowest floor elevation of
the dwelling and the high water level.
The applicant has requested to begin site grading after final plat and construction plan
approval. Staff finds this acceptable conditioned upon the applicant entering into the
development contract and providing the City with a financial security to guarantee site
restoration and erosion control measures.
STREETS
The applicant has submitted detailed street construction plans and specifications to staff for
review and formal approval by the City Council. Staff finds the plans and specifications in
conformance with City standards. The construction plans are also on the City Council's
agenda for formal approval in conjunction with this final plat consideration.
The street plans have been designed to provide access to all of the lots via a public street.
No private streets are proposed. With this phase of development, there is only one access
point in and out for the neighborhood. Stone Creek Drive will become a temporary deadend
street in excess of 4,500 feet from the intersection of Galpin Boulevard. A temporary
turnaround is being provided at the end of Stone Creek Drive with barricades indicating that
this street will be extended in the future. Eventually, Stone Creek Drive will be extended
northerly to tie into the City's east/west frontage road (proposed Coulter Boulevard) which
will eliminate the long deadend street scenario. A condition has should be added that the
applicant shall be responsible for extending Stone Creek Drive within three years after the
final plat approval of Creekside Addition. The applicant is also being required to provide a
financial security to guarantee construction and extension of said road.
The street plans propose on a 5 -foot wide concrete sidewalk to be extended from the existing
sidewalk in Hans Hagen development (Stone Creek 4th Addition). A sidewalk will be
installed along the west side of Stone Creek Drive. In addition, an 8 -foot trail is proposed to
meander along the Bluff Creek corridor along the east side of the development and will
connect to Stone Creek Drive.
UTILITIES
Detailed construction plans and specifications for the utilities have been submitted for staff
review and City Council approval. Staff finds the construction plans and specifications in
general conformance with the City's standards. The construction plans and specifications are
also on the City Council's agenda for formal approval in conjunction with the final plat
approval.
C

' Page 17
The applicant will be constructing a portion of the City's trunk sanitary sewer system in
' conjunction with the development. Staff recommends that the applicant be compensated for
the oversizing and extra depth cost associated with constructing the trunk sewer line versus an
8 -inch lateral line. Staff will be working with the applicant to arrive at an equitable
resolution for compensation for the oversizing of the sanitary sewer line. The applicant shall
be compensated by issuing credits against the properties assessment for the Upper Bluff Creek
trunk improvements.
Staff has also reviewed different alternatives to provide Timberwood Estates with future
sanitary sewer service. Staff has prepared a separate memo with the alternatives for
' extending a sewer line through this development to Timberwood Drive (see City Council Item
2b -3). The construction plans have been designed to extend an 8 -inch sanitary sewer line
along Lots 19 and 20, Block 3 to the plat boundary versus extending a line along the Bluff
' Creek tributary as previously considered with the preliminary plat review. This new
alignment will not require removal of any trees or have any impact to the creek. This option
gives the flexibility for two alternate routes into Timberwood Estates as well. The current
construction plans have been designed with this proposal. This work will be done in
conjunction with the overall development of Creekside Addition at no cost to the City.
' Staff has prepared a development contract for the applicant to enter into with the City and
provide the financial security to guarantee installation of the public improvements in
compliance with the conditions of approval for final plat.

Creekside Subdivision Narrative
Tree Preservation and Landscape Plan
Introduction
Creekside, a 48 unit subdivision located within the City of Chanhassen adjacent to Bluff Creek, is
committed to the tree preservation and protection of the natural woodlands, steep slopes and creek
corridor valleys. The residential subdivision was designed to minimize the impact to the existing
hardwood forest on the southern 1/4 of the site and all significant wetlands have been preserved.
Heritage Development is committed to utilizing retaining walls, minimize grading and promoting
advanced construction techniques so that the final residential subdivision and City may benefit
from the significant hardwood forest preservation.
Creekside Tree Preservation Philosophy
Heritage Development finds that trees provide many benefits including: stabilization of the soil by
the prevention of erosion and sedimentation, reduction of storm water runoff and the costs
associated therewith, improvement of air quality, reduction of noise pollution, control of urban heat
island effect, protection and increase of property values, protection of privacy, energy conservation
through natural insulation, control of drainage and restoration of denuded soil subsequent to
construction and grading, protection from severe weather, providing habitat for birds and other
wildlife, conservation and enhancement of the city's physical and aesthetic environment,
reforestation of open lands, and general protection and enhancement of the quality of life and
general welfare of the city.
Creekside Tree Preservation Plan
Heritage Development through RLK Associates, Ltd., prepared a tree preservation plan dated
April 26, 1995. This plan identifies the areas of proposed tree canopy protection, protected
wetland areas, storm water pondmg areas and wetland mitigation areas. The plan also identifies
the base landscape replacement plan which shall be installed by the developer. The species were
specifically selected based upon compatibly to the existing tree and soil conditions and for
promoting a quality hardwood tree environment throughout the subdivision.
Components of the Plan
EUPY
Framing Stone Creek Drive at Bluff Creek is a massing of conifer trees which signal to the
residents a visual land mark of entry/exit as one crosses the Bluff Creek.
-1®
7
0
Prominade
Stone Creek Drive has been established as the central spine of Creekside. A variety of hardwood
upland tree species have been selected to provide an overstory tree canopy. The tree species are
dominated by two varieties of Maple (the City's tree), three varieties of Oak, Hackberry,
Honeylocust and Linden. The trees, approximately 40' on center, will frame the public right -of-
way and provide a shaded and cooling micro climate for the public right -0f - -way which includes a
sidewalk and connections to the Bluff Creek trail system. Individual lots north of the southern
woodland are anticipated to be landscaped by the homeowners according to their specific landscape
ideas. The prominade of trees on Stone Creek Drive will entice the future residents to add to the
basic landscape plan. The Landscape Plan proposes an average of 2 to 3 trees to be installed on
each lot along Stone Creek Drive.
Upland Planting Buffer
The western edge of Creekside abuts an established large lot subdivision which is heavily wooded
and visually distant from Creekside for the great majority of the common property line. The
landscape plan provides a layer of planting to function as a screening element and transition zone
from the existing wooded edge and utility easement. A variety of species including conifers and
Amur Maples interspersed with canopy trees. The area within the easement paralleling the western
property line is proposed to be left in a natural/wild grass/ forbs condition. The reduced lawn area
will encourage invader tree and shrub species and promote wildlife and song bird nesting areas.
Woodland Lots
The nine lots located at the southern corner of Creekside have existing hardwood forest consisting
primarily of Sugar Maple and Bur Oak trees. The future home pads 60'x 60' and driveways have
been calculated into the overall tree preservation plan. The future homes are anticipated to be
designed specifically for each lot to minimize the grading and disruption to the significant trees
outside the designated home pads. Storage of excavation material will not be allowed on site of
lots 21, 23, 24, 25 and 26, outside of the designated 60 x 60 foot building pad area as generally
outlined on the plan dated April 26, 1995 and specifically delineated on the site specific building
permit application.
Tree Protection
Trees designated for preservation shall be protected by snow fences with clearly marked signage
specifying that area is off limits for construction activities. Protective barriers must be located at
the perimeter of the building pad and driveway area in order to completely protect trees being
saved and must remain in place until all construction activities are terminated. No equipment,
chemicals, soil deposits, or construction materials shall be placed within the protective barriers.
Any understory trees and natural vegetation should be preserved within the boundaries of the
protective areas. A preservation plan for lots 20, 21, 23, 24, 25, and 26 may include the use of
retaining walls, requirement for post- construction deep root fertilization and soil aeration, or
construction vehicle ramp systems. Preservation plans for the 6 above - mentioned lots will be
established at the time of building permit application. Individual grading, drainage, erosion control
plans will be required for lots 20, 21, 23, 24, 25, and 26, block 3, prior to issuance of building
permits. Vibratory plows shall also be utilized when cuts are near the limit of the protective zone.
As generally referenced on the April 26, 1995 Tree Preservation plan.

Future Landscaping Improvements
In addition to the boulevard tree planting provided by the developer and clusters of planting along
the western and eastern boundary of the site, future homeowners are strongly encouraged to install
additional landscape plantings to their private residences. A quality landscape plan should consist
of a variety of evergreen and deciduous shrubs, ornamental trees and over story trees. An
appropriate mixing of plant material and variety of ground cover (grass, shrubs, nativelwild
grasses) will enhance property values and wildlife habitat. In order to facilitate planting in
Creekside, the subdivision has been generally classified into four planting zones. Each zone has
characteristics which suggest certain plant materials be considered. The following zones and
planting lists identify suggested plantings which will allow the homeowner to expand upon as each
lot is personally landscaped.
Suggested Residential Plantings:
The site has been broken down into the following four zones.
Zone 1 Area East of Road

Natural Buffer Areas
The trail, wetlands and storm water pond areas located along the eastern edge of Creekside are
significant amenities for the residents and entire city population. Adjacent to the trail and or
stormwater pond, residents are encouraged to allow native vegetation to become established in
areas of 10' to 20' in width which will greatly enhance the natural beauty of the trail system. A
natural buffer is strongly encouraged along the entire eastern edge of the residential homes to
protect the natural areas from excessive use of fertilizer. Creekside residents will be encouraged to
use conservative amounts of fertilizer to prevent nutrient rich runoff.

MEMORANDUM
DATE: April 27, 1995
Revised May 3, 1995
TO: John Dobbs, Heritage Development Company
FROM: John Dietrich, RLK Associates
RE: Reforestation Plan, Creekside Subdivision
The reforestation plan which was approved in the preliminary plat subdivision identified 212* trees
to be planted to compensate for the tree canopy removed and required canopy coverage of 30 %.
The approved plan dated December 7, 1994 included the parcels of Block 2, Lots 8, 9, 10 and 11
in all of the calculations. The total acreage of these four lots is 2.46 AC. The City has requested
the reforestation calculations be rerun based upon Lot 8, 9, 10 and 11 being purchased by the City
as public open space. The net result of the revised calculation is identified below. Based upon the
meeting of April 26, 1995, between John Dietrich and Bob Generous of the City, the revised
reforestation plan will only apply if the Lots 8, 9, 10 and 11 are purchased by the City of
Chanhassen.
PROPOSED REFORESTATION PLAN

Existing Acreage 39.5 Acres
(Existing Wetland) 5.7 Acres
(Dedicated Park) 2.69 Acres
(Block 2, Lot 8, 9, 10, 11) 2.46 Acres
Net Acreage 28.65 Acres (Baseline)
1.) Existing Canopy Coverage 215,186 Sf. 4.94 Ac. Equal 17.3%
2.) Minimum Required 25% of Baseline (28.65 x 25) 311,998 Sq. Ft. 7.16 Ac.
3.) Existing Canopy Deficiencies
(311,998 - 215,186) = 96,812 Sf. Canopy Coverage
96,812 / 1089 = 89 Trees Required
4.) Tree Canopy Removed 72,400 Sf. /1.6 Ac.
5.) Replacement Tree Canopy
72,400 x 1.2 = 86,880 Sf.
86,880 / 1,089 = 80 Tree Replacement
6.) Resulting Number of Trees to Be Installed on Creekside Subdivision Are:
89 Canopy Deficiency
80 Replacement
169 Total Trees
If there are any questions regarding the figures, please contact John Dietrich at 933 -0972.
* The final reforestation plan dated April 26, 1995 identifies 179 trees needed for required tree
canopy coverage. The reduction from 212 trees is based upon adding 2.46 acres of park
dedication base line acreage calculation.
