CITY CODE TO CONSTRUCT A SINGLE FAMILY HOME.
City Council Summary – August 12, 2013
Kate Aanenson presented the staff report and Planning Commission update for this item. Councilman
Laufenburger asked if there were other variances granted for hard surface coverage in the area.
Councilwoman Tjornhom asked about runoff and drainage from this site. Councilwoman Ernst asked for
background information on the neighbors being told at one time that this property was not buildable.
Councilman McDonald asked for clarification of what type of house could be built on this property
without needing a variance. Mayor Furlong invited residents who filed the appeal to speak. Keith

property but were told by the City that it was unbuildable and that the owner, Anita Benson was making
pure profit on the sale of this property. Wally Schwab reiterated that he was told by city planning staff
that the lot was too small to build on. Mr. Nelson handed out a letter sharing his concerns. The applicant,
David Moore discussed the proposed house design. After comments from council members, the
following motion was made:
Councilman McDonald moved, Councilwoman Tjornhom seconded that the Chanhassen City
Council approves a 5.8 percent hardcover variance to permit the construction of a single family
home subject to the following conditions and adoption of the Chanhassen Board of Appeals and

and approval.
18.Percolation tests shall be performed in the bioretention area to determine infiltration
rates. The model shall be amended based upon these findings and provided to the city.
19.The bioretention feature shall be designed such that it drains within 48 hours.

2.All relocated trees shall be warranted for two seasons and replaced by developer if dead or
dying within that time period.
3.Advanced warning and speed advisory signs are required where the design speed is less than
30 mph.
4.The site plan and HydroCAD model must be revised to address the following comments:
a.Peak discharge rates are proposed to increase at the following locations:
i.Runoff leaving the overall site for the snowmelt events.
ii.Runoff leaving the western portion of Wetland A for the 2, 10 and 100 year design
events.
iii.Runoff leaving the site to the north of the eastern portion of Wetland A for the
snowmelt event.
iv.Runoff leaving the site to the north of the western portion of Wetland A for all events.
b.The drainage areas and/or curve number in the HydroCAD model must correspond to the
Drainage Area and Curve Number Table.
c.Directly connected impervious areas must be modeled separately rather than included in
the composite Curve Number computation.
d.The applicant must provide calculations (or submit a model) demonstrating that the city’s
requirements for water quality are satisfied.
i.If the event-based NURP standard cannot be achieved by dead pool storage, then (P8
or other) calculations should be based on equivalent annual removal efficiencies.
ii.If an iron-enhanced filtration system is included in the design, calculations should be
provided demonstrating the water quality treatment benefits of the BMP. Detailed
plans of the system should be submitted for review with the calculations.
iii.The report notes that the east pond is able to remove 87.8% of the phosphorus load.
This removal efficiency appears excessively high. It is anticipated that there is either
an error with the model inputs or the calculation was performed for a particular
rainfall event rather than annualized removal efficiency.
5.The developer shall obtain off-site easements over the existing swale and 18” culvert.
11
City Council Summary – August 12, 2013

8.If groundwater is encountered during site construction the lowest floor elevations must be
adjusted so that there is a minimum three-foot separation.

a.The developer must obtain a MnDOT permit for the proposed grading within the
MnDOT right-of-way.
b.It is difficult to discern between the proposed contours, lot lines and setback lines. The
developer’s engineer is requested to change the drawing line weights.
10.Some homes may choose to install a privately-owned and maintained booster to provide a
higher water pressure.
11.The watermain shall be 8-inch PVC (C-900).

pond maintenance access.
18.The applicant must apply for and receive an NPDES permit from the Minnesota Pollution
Control Agency and provide evidence to the city prior to grading the site.
19.The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone
document and submitted to engineering for review and comment prior to final plat approval.
This SWPPP shall include a narrative, plan set and applicable details.
20.The SWPPP must include the required elements as listed in Part III of the National Pollution
Discharge Elimination System General Permit Authorization to Discharge Stormwater
Associated with Construction Activity (NPDES Construction Permit) and in the MPCA
SWPPP checklist.

be reduced below existing discharge rates or efforts must be taken to stabilize these discharge
points to prevent further channel incision and head cutting.

management plan must be developed showing how these areas will be permanently
stabilized.

review for all areas preserved as open space including those areas graded for the construction
of stormwater management practices and the installation of utilities that are above the normal
water level prior to final plat approval.
26.Minnesota Department of Transportation right-of-way is outside of the City of Chanhassen’s
WCA jurisdiction as MnDOT is their own LGU. Chanhassen’s review of wetland
