§ 20-508. Standards and guidelines for single-family attached or cluster-home PUDs.

(a)

Generally. Single-family attached, cluster, zero lot line, townhouses and similar type dwelling types may be allowed on sites designed for low, medium or high density residential uses by the City of Chanhassen Comprehensive Plan.

(b)

Minimum lot sizes. There shall be no minimum lot size; however, in no case shall net density exceed guidelines established by the city comprehensive plan.

(c)

Setback standards/structures and parking:

(1)

PUD exterior: 50 feet. The 50-foot PUD exterior setback may be changed, increased or decreased, by the city council as part of the approval process when it is demonstrated that environmental protection or development design will be enhanced.

(2)

Interior public right-of-way: 30 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.

(3)

Other setbacks: Established by PUD agreement.

(d)

Protection and preservation of natural features. 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.

(e)

Landscaping plan. An overall landscaping plan is required. The plan shall contain the following:

(1)

Boulevard plantings. Located in front yards shall require a mix of over-story trees and other plantings consistent with the site. Landscaped berms shall be provided to screen the site from major roadways, railroads and more intensive land uses. In place of mass grading for building pads and roads, stone or decorative blocks 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)

Foundation and yard plantings. A minimum budget for foundation plants shall be established and approved by the city. As each parcel is developed in the PUD, the builder shall be required to install plant materials meeting or exceeding the required budget prior to issuance of certificate of occupancy or provide financial guarantees acceptable to the city.

(4)

Tree preservation. Tree preservation is a primary goal of the PUD. A detailed tree survey should be prepared during the design of the PUD and the plans should be developed to maximize tree preservation.

(f)

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:

(1)

Standards for exterior architectural treatments.

(2)

Prohibition against freestanding 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.
