WETLAND ALTERATION PERMIT #2006-32
Permit. Subject to the terms and conditions set forth herein, the City of Chanhassen permits a
wetland alteration permit to allow 0.58 acres (25,382 square feet) of wetland impact for the
construction of access to the western portion of the applicant's property and stormwater ponding.
Wetland replacement will occur on site with the construction of 0.83 acres (36,104 square feet)
of new wetland,. in combination with 0.87 acres (37,921 square feet) of credit through
stormwater ponding and upland buffer creation.
1. Property. The permit is for property situated in the City of Chanhassen, Carver County,
Minnesota, described as follows:
Outlot A, Butternut Ridge Addition
2. Conditions. The Wetland Alteration Permit was approved as shown on the plans dated
received September 5, 2006 and subject to the following conditions:
a) Because the species of spike rush was not identified during the delineation, the dominant
spike rush within Wetland B shall be keyed out to ensure that the increased period of
inundation will not adversely affect a state-threatened plant species or a significant natural
community.
b) The plans shall be revised to show how M-l will be accessed. The access route shall be
stable, shall avoid damage to significant trees (greater than 10" DBH) and shall avoid
impacts to natural drainageways and any jurisdictional wetlands that may exist on site that
were not delineated by Westwood Professional Services in August 2006.
c) A planting plan for M-l, including invasive vegetation management techniques, species to
be planted, proposed planting rates, and the approach to upland buffer restoration, shall be
submitted prior to final City Council approval.
d) The applicant shall submit a letter of credit equal to 110% of the cost of the wetland
creation (including grading and seeding) to ensure the design standards for the
replacement wetland are met. The letter of credit shall be effective for no less than five
1
years from the date of final plat approval. The applicant shall submit a cost estimate for
wetland creation (including grading and seeding) so the City can calculate the amount of
the wetland creation letter of credit.
e) A five-year wetland replacement monitoring plan shall be submitted. The replacement
monitoring plan shall include a detailed management plan for invasive non-native
species, particularly hybrid cattail, purple loosestrife and reed canary grass. The plans
shall show fixed photo monitoring points for the replacement wetland. The applicant
shall provide proof of recording of a Declaration of Restrictions and Covenants for
Replacement Wetland.
f) A wetland buffer 16.5 to 20 feet in width (with a minimum average of 16.5 feet) shall be
maintained around all wetlands. Wetland buffer areas shall be preserved, surveyed and
staked in accordance with the City's wetland ordinance. The applicant shall install wetland
buffer edge signs, under the direction of City staff, before construction begins and shall pay
the City $20 per sign.
g) A berm is proposed within the existing right-of-way (ROW) for Powers Boulevard. The
applicant shall receive approval from Carver County forthe proposed normal water level
(NWL) in Pond 1 and for the proposed berm.
h) At this time, no development is approved for the "Future Development Area." Any future
development and/or requested changes to the land use for this property shall undergo the
City's development and land use review process(es). .
i) Stormwater calculations were not submitted for Pond 1. When the future development area
is developed, the pond shall meet all stormwater requirements in place at that time.
j) The east-west road will be a field road that will extend from Powers Boulevard shall only
serve the future development area identified on the plan and the future lift station. This road
shall not extend further east.
k) Future utility installation shall be a lighter line weight than the proposed storm sewer
installation that will be done in conjunction with the wetland alteration.
I) The silt fence along Powers Boulevard shall be installed east of the trail at the construction
limits. The rock construction entrance shall be at least 75 feet in length. The plans shall be
revised to show the City's standard details 3107, 3108, 5300, 5301 and 5302A.
m) The temporary riser structure shall remain in place until the pond and adjacent areas are
stable.
n) 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:
2

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 man made systems that discharge to a surface water.
0) Street cleaning of soil tracked onto public streets shall include daily street scraping and
street sweeping as-needed.
p) A building permit shall be obtained for all retaining walls greater than four (4) feet in height.
q) The applicant shall apply for and obtain permits from the appropriate regulatory agencies
(e.g., Minnesota Pollution Control Agency (NPDES Phase IT Construction Permit),

with their conditions of approval."

of the terms of this permit.
4. Lapse. If within one year of the issuance'of this permit the authorized construction has not been
substantially completed or the use commenced, this permit shall lapse, unless an extension is
granted in accordance with theChanhassenZoning Ordinance. ,
5. Criminal Penalty. Violation of the terms of this conditional use permit IS a criminal
misdemeanor.
