ORDINANCE NO. 179
AN ORDINANCE AMENDING CHAPTER 20 OF THE
CHANHASSEN CITY CODE, THE ZONING ORDINANCE CONCERNING
RESIDENTIAL PLANNED UNIT DEVELOPMENTS
The City Council of the City of Chanhassen ordains:
Section 1. Section 20-506 of the Chanhassen City Code is amended as follows:
Section 20-506. Standards and Guidelines for Single Family Detached Residential Planned Unit
Developments.
Intent
The use of Planned Unit Developments for residential purposes should result in a
reasonable and verifiable exchange between the city and the developer. The developer gains the
potential for offering reduced lot sizes and flexibility in development standards which results in
a combination of reduced development costs and improved marketing flexibility. At the same
time, the city should be offered enhanced environmental sensitivity beyond normal ordinance
requirements. Lot sizes should reflect the site's environmental limitations and opportunities and
to offer a range of housing pricing options. In addition, quality of development, as evidenced
by landscaping, construction quality, provision of public/private open and recreational space,
should also be enhanced.
a) Minimum Lot Size - The single family residential PUD allows lot sizes down to a
minimum of 11,000 square feet (excluding identified wetland areas from lot calculations).
Average lot sizes for the entire PUD shall maintain a minimum area of 15,000 square
feet. The applicant must demonstrate that there are a mix of lot sizes consistent with
local terrain conditions, preservation of natural features and open space and that lot sizes
are consistent with average building footprints that will be concurrently approved with the
PUD. The applicant must demonstrate that each lot is able to accommodate a 60' x 40'
building pad and 12' x 12' deck without intruding into any required setback area or
protective easement. Each home must also have a minimum rear yard, 30 feet deep. This
area may not be encumbered by the required home/deck pads or by wetland/drainage
easements. It may include areas with steep terrain or tree cover.
b) Minimum Lot Width at Building Setback - 90 feet.
c) Minimum Lot Depth - 100 feet.
0 1
• d) Minimum Setbacks:
PUD Exterior - 30 feet
Front Yard - 30 feet*
Rear Yard - 30 feet
Side Yard - 10 feet
* The 30 foot front yard setback may be waived by the City Council when it is
demonstrated that environmental protection will be enhanced. In these instances, a
minimum front yard setback of 20 feet shall be maintained.
Accessory Buildings and Structures - located adjacent to or behind principal structure a
minimum of 10 feet from property line.
e) The applicant must demonstrate that the flexibility provided by the PUD is used to protect
and preserve natural features such as tree stands, wetlands, ponds, and scenic views.
These areas are to be permanently protected as public or private tracts or protected by
permanently recorded easements.
f) An overall landscaping plan is required. The plan shall contain the following:
1) Boulevard Plantings - Located in front yard areas these shall require a mix of
over -story trees and other plantings consistent with the site. A minimum of over -
story trees must be provided in each front yard. Well designed entrance
monument is required. In place of mass grading for building pads and roads,
stone or decorative block retaining walls shall be employed as required to preserve
mature trees and the site's natural topography.
2) Exterior Landscaping and Double Fronted Lots - Landscaped berms shall be
provided to buffer the site and lots from major roadways, railroads, and more
intensive uses. Similar measures shall be provided for double fronted lots. Where
necessary to accommodate this landscaping, additional lot depth may be required.
3) Rear Yard - The rear yard shall contain at least two over -story trees. Preservation
of existing trees having a diameter of at least 6 inches at 4 feet in height can be
used to satisfy this requirement of the PUD and the plans should be developed to
maximize tree preservation.
g) Architectural Standards - The applicant should demonstrate that the PUD will provide for
a high level of architectural design and building materials. While this requirement is not
intended to minimize design flexibility, a set of architectural standards should be prepared
for city approval. The primary purpose of this section is to assure the city that high
quality design will be employed and that home construction can take place without
variances or impact to adjoining lots. The PUD Agreement should include the following:
0 2
• 1) Standards for exterior architectural treatments.
2) Prohibition against free standing garages may be required by the city when it is
felt that unattached garages will be difficult to accommodate due to small lot
sizes. If an attached garage is to be converted to living space at some time in the
future, the applicant will have to demonstrate that there is sufficient room to
accommodate a two car garage without variances to obtain a permit.
3) Guidelines regulating the placement of air conditioners, dog kennels, storage
buildings, and other accessory uses that could potentially impact adjoining parcels
due to small lot sizes.
Section 2. Chapter 20 of the Chanhassen City Code is amended by adding Section 20-508

C!
. Section 3. Section 20-505 of the Chanhassen City Code is amended by adding the
following subparagraphs:
(m) Buffer yards. The City Comprehensive Plan establishes a requirement for buffer
yards. Buffer yards are to be established in areas indicated on the Plan where higher intensity
uses interface with low density uses. In these areas, a fifty (50) foot buffer yard is to be
provided where the interface occurs along a public street, a one hundred (100) foot buffer yard
is required where the interface occurs on internal lot lines.
The buffer yard is an additional setback requirement. It is to be cumulatively calculated with the
required setbacks outlined above. The full obligation to provide the buffer yard shall be placed
on the parcel containing the higher intensity use.
The buffer yard is intended to provide additional physical separation and screening for the higher
intensity use. As such, they will be required to be provided with a combination of berming,
landscaping and/or tree preservation to maximize the buffering potential. To the extent deemed
feasible by the city, new plantings shall be designed to require the minimum of maintenance,
however, such maintenance as may be required to maintain consistency with the approved plan,
shall be the obligation of the property owner.
Buffer yards shall be covered by a permanently recorded conservation easement running in favor
of the city.
• In instances where existing topography and/or vegetation provide buffering satisfactory to the
city, or where quality site planning is achieved, the city may reduce buffer yard requirements by
up to 50%. The applicant shall have the full burden of demonstrating compliance with the
standards herein.
Section 4. This ordinance shall be effective immediately upon its passage and publication.
PASSED AND ADOPTED by the Chanhassen City Council this 23rd day of November,
