PUBLIC HEARING:
960 CARVER BEACH ROAD: REQUEST FOR A VARIANCE FROM SECTION 20-615 OF
THE CHANHASSEN CITY CODE TO CONSTRUCT A SINGLE-FAMILY HOME ON
PROPERTY ZONED RESIDENTIAL SINGLE FAMILY (RSF) AND LOCATED AT 960
CARVER BEACH ROAD. APPLICANT: DAVID D. MOORE, INC. OWNER: ANITA
BENSON. PLANNING CASE 2013-15.
Kate Aanenson presented the staff report on this item. Chairman Aller clarified background information
before asking the applicant, David Moore to explain the variance request. Chairman Aller opened the
public hearing. Keith Peterson, 921 Hiawatha Drive provided background information regarding when
the lot was for sale in 1999 and the City told the neighbors the lot was not buildable and how adjoining
neighbors were going to buy the property to add onto their lots but a city employee bought the lot before
they could finish the deal. Wally Schwab, 950 Carver Beach Road spoke to the fact that when Ms.
Benson was granted a variance it was because to deny it would be considered a taking and his concern
with a building of any size being crammed into this sub-standard sized lot. Dick Roe, 6771 Penamint
stated he could support a single story house that meets the setbacks but could not support a two story
Planning Commission Summary – July 16, 2013
house. Katie Eckhoff, 920 Hiawatha Drive expressed concern that cramming a house on this tiny, little
lot will bring the value of their house down. Chairman Aller closed the public hearing.
Hokkanen moved, Yusuf seconded that the Planning Commission, as the Board of Appeals and
Adjustments, approves a 5.8% hard cover variance to permit the construction of a single-family
home subject to the following conditions and adoption of the attached Findings of Fact and
Decision:
1. The builder shall provide a tree survey as part of the building permit process. The builder shall
try to preserve the trees at the perimeter of the property.
2. The building shall be limited to the split level house design.
3. The builder shall apply for a building permit and meet all requirements of said permit.
All voted in favor and the motion carried unanimously with a vote of 4 to 0.

CASE 2013-08.
Sharmeen Al-Jaff presented the staff report on this item. Commissioner Withrow asked for clarification
on the amount of land donated to the City, and results from soil borings. The applicant, Dave Pokorney
with Community Asset Development Group, 1403 Valley View Road, Chaska stated they were excited
about this use for the property and did not have any issues with the conditions in the staff report.
Chairman Aller asked the applicant to explain further the use associated with the senior housing facility.
Commissioner Withrow asked about patios or decks. Chairman Aller opened the public hearing. Chris
Hammer, 9688 Washington Boulevard stated his concern over potential future impact to the wooded area
of Bluff Creek and the effect on their home values. Colleen Kroll, 2694 Shadow Wood Court asked if the
donated property from Mr. Klingelhutz would become parks and trails, the effects of the easement for
Pioneer Trail expansion in the future, sewer hook-up into the city of Chaska, and the impact of the
location of the houses to their home. Jeff Kerfeld, 2702 Shadow Wood Court asked for clarification of
the sewer hook-up to their neighborhood in Chaska, grading impact affecting wildlife habitat, and
concerns with lighting and runoff. Emily Owen, 2706 Shadow Wood Court shared her neighbor’s
concerns as well as a concern with increased traffic. Keith Wyman, 2674 Shadow Wood Court expressed

2.All relocated trees shall be warranted for two seasons and replaced by developer if dead or
dying within that time period.
3.The applicant shall show proof to the city of permission by MnDOT to place landscape
materials on state right-of-way.
4.The applicant shall increase bufferyard plantings along the south property line to meet
minimum requirements.
5.Advanced warning and speed advisory signs are required where the design speed is less than
30 mph.
6.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 two-year (2.8-inch) rainfall and snowmelt
events.
ii.Runoff leaving the wetland located on the western portion of the site for each design
event.
iii.Runoff leaving the site to the north for the snowmelt event.
b.Use a pond in the model at the 18-inch culvert located north of the site.
c.The analysis should reflect any overtopping of the driveway or other overland flows that
may occur.
d.Due to the increased velocities through the12-inch culvert leaving the western wetland,
the developer must provide a design to address associated erosion at this location. Any
required improvements outside of existing easements shall require additional easements.
e.The drainage areas and/or curve number in the HydroCAD model must correspond to the
Drainage Area and Curve Number Table.
f.Directly connected impervious areas must be modeled separately rather than included in
the composite Curve Number computation.
g.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.
11
Planning Commission Summary – July 16, 2013
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.
7.The HydroCAD model must be revised so that the impervious surface of the lots is 30%.
8.If groundwater is encountered during site construction the lowest floor elevations must be
adjusted so that there is a minimum three-foot separation.
9.The developer must provide additional information showing how the proposed
“Preservation/Stormwater Volume Reduction Area” between the large wetland and the back
of Lots 4-7, Block 1 will meet the minimum requirements.
10.Storm sewer sizing calculations must be submitted with the final plat application and shall
include the existing storm sewer at Tigua Lane (approximately 280 feet east of the proposed
street intersection). The existing 12-inch reinforced concrete pipe north of Lots 7 and 8,
Block 1 shall also be included in the analysis.
11.The grading plan must be revised to address the following comments:
a.The developer must obtain a MnDOT permit for the proposed grading within the
MnDOT right-of-way.
b.The grading plan must be revised at the slope down from the street to the wetland at
Station 3+00, and between Lots 3 and 4, Block 1 so the slope does not exceed 3H:1V.
c.The lowest openings of Lots 2 and 3, Block 2 must be at least one foot above the
emergency overflow elevation.
d.The minimum floor elevation of Lots 8, 9 and 10, Block 1 shall be 897.6’.
e.The building envelope for Lot 3, Block 2 must not encroach into the drainage and utility
easement.
f.The side yard drainage and utility easements between Lots 10 and 11, Block 1 must
match what is shown on the plat.
g.The building pad shown for Lot 1, Block 2 cannot accommodate any of the house styles
provided and must be revised accordingly.
h.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.
12.A building permit is required to construct the proposed retaining wall. Plans must be
submitted with the permit application and must be signed by an engineer registered in the
State of Minnesota.
12
Planning Commission Summary – July 16, 2013
13.Some homes may choose to install a privately-owned and maintained booster to provide a
higher water pressure.
14.The watermain shall be 8-inch PVC (C-900).
15.Prior to final submittal the developer must obtain the necessary easement to install the
sanitary sewer off-site, to the north.
16.A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in
the rate in effect at that time.
17.Street and utility plan and profile construction plans must be submitted with the final plat.
18.The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone
document and submitted to engineering for review and comment. This SWPPP shall include
a narrative, plan set and applicable details.
19.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.
20.A detailed erosion prevention and sediment control plan must be submitted for review and
approval per the requirements of Section 19-145 of Chanhassen City Code and the NPDES
Construction Permit. This should include, among the other listed requirements, all temporary
and permanent best management practices.
21.There is significant evidence of gully erosion at both off-site discharge locations. Rates must
