seconds East, along said west line, a distance of 615.32 feet to the point of beginning.
Subject to County Road No. 17 over the westerly 33;00 feet of the above described parcel.
The approval of the subdivision is subject to the following conditions:
1
1. Lot 1, as shown in the preliminary plat, shall be designated as Outlot A until the ultimate
development of the lot is determined and a revised grading plan submitted that shows the
wetland impacts.
2. The applicant shall use BWSR U8 in all graded areas along the eastern property line.
3. Existing City boulevard trees will be protected with fencing during all phases of
construction. The applicant will be responsible for replacing any trees that die as a result
of construction activity.
4. The north lot will be required to provide buffer yard and parking lot landscaping as
required by ordinance at the time of site plan approval.
5. All trees on the north lot within the wetland buffer and setback shall be preserved until a
final grading plan is approved for the lot. The developer shall work with staff as part of
the development of the site to preserve these trees through revised grading and the use of
retaining walls.
6. A wetland buffer 20 feet in width and a 30-foot setback from the wetland buffer must be
maintained around all wetlands on the property. Secondary structures are allowed to
encroach up to 50% of the setback. It appears that the retaining wall has exceeded the
allowed encroachment and needs to be moved out of this 15-foot setback. Wetland buffer
areas shall be preserved, surveyed and staked in accordance with the City's wetland
ordinance. The applicant must instal! wetland buffer edge signs, under the direction of
City staff, before construction begins and must pay the City $20 per sign.
7. The retaining wall needs to be moved so that it is at least 15 feet from the edge of the
buffer or 35 feet from the wetland edge.
8. A NPDES Phase II Construction Site Storm Water Permit will be required from the
Minnesota Pollution Control Agency (MPCA) for this site.
9. The proposed storm water pond shall be constructed prior to disturbing upgradient areas
and used as a temporary sediment basin during mass grading. Diversion berms/ditches
may be needed to divert water to the pond and a temporary pond outlet shall be provided.
The outlet could be a temporary perforated standpipe and rock cone. The plans shall be
revised to include a detail for the temporary pond outlet.
10. A detailed construction plan needs to be created for the pond construction which shows
how water quality of the existing pond and adjacent water body will be protected. At a
minimum, this must show how the pond will be dewatered and what best management
practices will be employed.
2
11. All silt fence that is not laid parallel to the contours shall have J Hooks installed every 50-
75 feet.
12. A stable emergency overflow (BOP) for the stormwater pond shall be provided. The EOP
could consist of riprap and geotextile fabric or a turf reinforcement mat (a permanent
erosion control blanket). A typical detail shall be included in the plan. The overland
route from the EOF to the existing wetland shall be shown on the plans and shall be
encumbered by a drainage and utility easement.
13. Erosion control blanket shall be installed on all slopes greater than or equal to 3: 1. All
exposed soil areas shall have temporary erosion protection or permanent cover year
round, according to the following table of slopes and time frames:
Tvpe of Slope
Steeper than 3:1
10:1 to 3:1
Flatter than 10: 1
Time
7 days
14 days
21 days
(Maximum time an area can
remain open when the area
is not actively being worked.)
These areas include constructed storm water management pond side slopes, and any
exposed soil areas with a positive slope to a storm water conveyance system, such as a
curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other
natural or manmade systems that discharge to a surface water.
14. Inlet protection may be needed prior to installation of the castings for the curbside catch
basins. In that case, all storm sewer inlets shall be protected by at least fabric draped over
the manhole with a steel plate holding the fabric in place.
15. At this time, the estimated total SWMP fee, due payable to the City at the time of final
plat recording, is $59,365.80.
16. The applicant shall apply for and obtain permits from the appropriate regulatory agencies
(e.g., Minnesota Pollution Control Agency, Minnesota Department of Natural Resources
(for dewatering)) and comply with their conditions of approval.
17. Full park fees in lieu of parkland dedication and/or trail construction shall be collected as
a condition of approval for this subdivision. The park fees shall be collected in full at the
rate in force upon final plat submission and approval.
18. Approval of the subdivision in no way should convey to the applicant, the land owner or
any subsequent owners and occupants approval of the wetland impacts indicated within
Wetland 2 as shown on the conceptual grading plan or any other wetland impacts
resulting from the development of this parcel. Any grading which, as a result of the
development of Lot 1, occurs on Lot 2 must provide sediment and erosion control best
management practices to protect the wetland and the buffer area.
3
19. No burning shall be issued for trees to be removed. Trees and shrubs must be removed
from site or chipped.
20. Remove all existing structures prior to the commencement of grading.
21. This site must be mass graded to minimize future truck traffic upon completion of the
southern parcel. A 20-foot buffer is required around the wetland on the northern parcel to
prevent grading from taking place. Please revise the grading plan and show silt fence in
this location so the contractor can determine the grading limits. Also, the building pad
elevation of the northern parcel shall be lowered to an elevation of 952 to minimize the
impacts to the wetland.
22. The grading plan needs to be revised. The proposed contours on the northern property
need to be revised showing the wetland buffer of 20 feet. Show the existing conditions
within 100 feet of the property line.
23. Normal water level of the existing wetlands should be shown on the plan. Also, include
the normal water level and high water level of the revised pond. Show emergency
overflows on the plan. Keep a minimum of 2 percent slope in the grass areas, i percent
in the pavement areas, and .5 percent along the curb lines.
24. Development of the northern parcel will require a stormwater pond to treat the water prior
to discharge into the wetland. This pond should discharge to the wetland northeast of the
site.
25. Revise the drainage calculations. The existing drainage map should include three areas:
One area discharges to the northern wetland, one to the eastern wetland and one to the
existing pond. Revise the calculations to show the pre- and post-development peak
discharge into the northern and eastern wetland. Post-development peak discharges must
remain less than pre-development peak discharges for the 2-, 10-, and 100-year storm
events. Drainage calculations must be signed by a Professional Engineer registered in the
State of Minnesota.
26. Rational method calculations, including drainage map, must be provided for the sizing of
the storm sewer.
27. IT importing or exporting material for development of the site is necessary, the applicant
will be required to supply the City with detailed haul routes.
28. Building permits are required for all retaining walls four feet tall or higher and must be
designed by a Structural Engineer registered in the State of Minnesota. Additional top
and bottom elevations should be added to the retaining wall.
29. All of the utilities within the boundary spould be privately owned and maintained. These
utilities must be covered by a cross-access agreement. The proposed watermain
4
connection into Chanhassen Lakes Business Park 7th Addition must wet tap the existing
watennain.
30. Utility plans shall show both plan view and profiles of all utilities (sanitary sewer, water,
and stonn sewer lines).
31. Detennine actual elevations of existing utilities. A minimum vertical separation of 18
inches is required at all stonn, sanitary, and watennain crossings. Provide details of each
crossing to ensure minimum separation.
32. Each new lot is subject to the sanitary sewer and water hookup charges. Lot 1, Block 1
will get credit for 8 trunk sanitary sewer charges. Lot 2 will get credit for 15 trunk
sanitary sewer charges. No truJ1k water charges have been paid. The 2008 trunk hookup
charge is $1,769 for sanitary sewer and $4,799 for watennain. Sanitary sewer and
watennain hookup fees may be specially assessed against the parcel at the time of
building permit issuance. All of these charges are based on the number of SAC units
assigned by the Met Council and are due at the time of building permit issuance.
33. All of the utility improvements are required to be constructed in accordance with the
City's latest edition of Standard Specifications and Detail Plates. The applicant is also
required to provide the City with the necessary financial security in the fonn of a letter of
credit or cash escrow in the amount of $13,200.00 to guarantee the installation of the
pond, erosion control, and seeding. The applicant must also notify the City after
installation of the erosion control and 48 hours prior to the commencement of grading.
Permits from the appropriate regulatory agencies wi!! be required, including the ~1PCA
and the Dept. of Health.
34. Easements are required to provide access to Lot 1, Block 1. A private drive easement
will be required to provide access to Lot 1, Block 1 off of Audubon Road. An additional
private easement will be required to provide truck access through Chanhassen Lakes
Business Park 7th Addition and up to Lot 1, Block 1. The easements for the gas line and
power line must be shown on the plat. No work will be allowed in this area without the
approval of the owner of the easement. A drainage and utility easement will be required
over the proposed pond for Lot 2, Block 1. Also, a temporary drainage and utility
easement should be placed on the entire Lot 1, Block 1 until the time of final plat of this
parcel. Provide location and easement for pond access.
35. Shift proposed drive off of Audubon Road so that the center of the driveway is located 70
feet north of the Kingdom Hall drive. Due to limited site distance, this driveway location
will be limited to passenger vehicles only. Truck-trailer access must be provided to Lot
1, Block 1 through Chanhassen Lakes Business Park 7th Addition.
36. The boundary survey and preliminary plat need to be revised. Add existing conditions
and property lines within 100 feet ofthe boundary. Also, the legal description does not
match the bearings on the preliminary plat.
