B. Land Use Design Criteria: In addition to the general conditions requirement stated within this document, the following land use design criteria shall apply to the development within the PUD. The following development standards and use regulations shall apply to development within each of the individual parcels, or portions of said parcel, as applicable:
1. Parcel A: All general use regulations and provisions set forth in title 9, "Zoning", of the city code for single-family residential district (RS-5) with a minimum lot size of five thousand (5,000) square feet shall apply to any development proposal for property within parcel A as shown on the sketch plan of the Maple Grove West PUD ordinance, unless noted otherwise in this ordinance.
a. Architectural Design: Architectural design for single-family units shall attempt to express a creative presentation of exterior building materials, exterior details and texture, treatment of windows and doors, use of angles and multiplicity of planes within wall and roof design. Residential units should incorporate the use of brick, natural stone, roof materials, decorative moldings, cornices, and trim elements, or combination of design materials that provide variation of architectural styles or elements.
In those cases where the front wall of the garage extends more than ten feet (10') beyond the front wall of the residence, the width of the residence shall be required to be equal to or greater than the width of the garage unit and the garage elevations will be required to include a window element to lessen its dominance of the residential structure.
The petitioner will need to submit design criteria for the development of the single-family residential lots for approval by staff at the time of final plat review.
b. Setbacks: All residential structures shall comply with a twenty foot (20') front yard setback and a thirty five foot (35') rear yard setback, with the exception for those lots that abut a buffer park, where a twenty five foot (25') rear yard setback will be allowed. A minimum of a five foot (5') side yard building setback will be allowed.
Front porches shall have a usable area that is no less than five feet (5') in width, and may be allowed to extend into the front yard building setback, but no closer than fifteen feet (15') to the front property line.
A residence with a side loaded garage may be set back a minimum of twenty feet (20') measured from the front property line.
Garage units shall comply with a minimum setback of twenty five foot (25') front yard setback measured to the garage door. It is encouraged that garage doors facing the public street shall not extend beyond the front facade of the residential unit to minimize the dominance of their appearance. It is also encouraged that the front walls of any garage be set back a minimum of five feet (5') from the front facade of the residential structure. (Ord. 1646, 9-26-2005)
c. Buffers: A thirty foot (30') buffer park shall be required to be provided along 98th Street and Chalk Street and shall be designated as an outlot to be owned and maintained by the property owners' association. The developer shall be responsible for the costs of landscaping and its installation in the landscape buffer area.
A thirty foot (30') buffer park easement will be required along the Union Pacific Railroad. All required building setbacks shall be measured from the easement line of the required buffer park easement.
No fences shall be allowed to be constructed within the thirty foot (30') buffer park located along 98th Street or Chalk Street. Fences shall be allowed to be constructed within the thirty foot (30') buffer park located within lots 6 through 15, Maple Grove West plat 1; however, said fences must be designed and constructed in such a manner so as to allow city access to existing public storm sewer and manholes, including the removal of fence panels and structural members should such be deemed necessary to accommodate maintenance and repair equipment/measures. (Ord. 1971, 1-7-2013)
2. Parcel B: All general use regulations and provisions set forth in title 9, "Zoning", of the city code for residential medium- density (RM-12) district, unless noted otherwise herein. (Ord. 1646, 9-26-2005)
a. Architecture: Architectural design for multi-family buildings shall express a creative presentation of exterior building materials, exterior details and texture, treatment of windows and doors, and use of angles and multiplicity of planes within the wall and roof design to lessen the plainness of appearance which can be characteristic of large residential buildings. The use of building articulation that breaks up the building mass into modules which reflect proportions similar to the single-family residential dwellings shall be required. Methods used to create intervals which reflect individual dwelling units are:
(1) Facade modulation - stepping back or extending forward a portion of the facade.
(2) Entrances to the dwelling units should be easily and individually identified through the use of design and detailing. Projected or recessed entryways, higher rooflines, awnings or changes in materials are examples that can create this effect.
(3) Changing the rooflines by alternating dormers, stepped roofs, gables, or other roof elements to reinforce the modulation or articulation interval.
(4) Changing materials with the change in building plane to vary the look of the individual dwelling units.
(5) Using paint and materials to reinforce the modulation or articulated intervals.
Buildings shall use materials such as brick, stone, vertical or lap siding, shakes and stucco, combining materials along with trim and details to provide visual interest within the development. Use of natural materials is encouraged, composite materials such as fiber cement and wood composites are appropriate substitutions. Vinyl siding may be used only with appropriately scaled trim. All material, trim and details for a building shall be designed appropriately for chosen architectural style. Materials should change with the change in building planes. Trim and structural elements such as posts or columns shall be sized to the scale of the building. When used, masonry materials shall have the appearance of three-dimensional elements. Fenestration (door and window openings) shall be sized to the scale of the building, incorporated on all sides of the building and be compatible to the chosen architectural style. Asphaltic shingles shall be allowed provided the shingle materials are of a heavier grade that produces a shake or shadowing effect and is consistent with the color and materials used for the multi-family residential developments.
Garage doors facing the public street should be set back to minimize the dominance of their appearance or staggered across the building facade to create opportunities for individuality of the dwelling units. The architectural details of garage should incorporate the materials and treatments of the dwelling unit, such as windows, doors, paint and materials, and style of the dwelling unit.
All facades of the building in unobstructed view of the public shall be treated with the same level of architectural style and detail.
b. Setbacks: All residential structures and garages shall comply with all general use regulations and provisions set forth in title 9, "Zoning", of the city code for residential medium- density district (RM-12) shall apply, unless noted otherwise within this section.
A building front yard and perimeter setback of thirty five feet (35') shall apply to any structure within parcel B, except that the perimeter setback adjacent to municipal property at the time of development of any part of parcel B shall be twenty five feet (25'). If the property abuts a private street, any residential structure shall be allowed to be located no closer than fifteen feet (15') from the back of a curb or back of a sidewalk, whichever is more restrictive. Garages shall comply with a front yard setback of twenty five feet (25'), to be measured from the garage opening to the back of a curb for garages opening onto a private street where the sidewalk is immediately adjacent to the private street. In those cases where the garage opens onto a public street, the front yard setback for garages shall be twenty five feet (25') to be measured from the garage opening to the back of sidewalk.
A building separation of a minimum of fifteen feet (15') is required for all one- and two-story structures. Any structure greater than two (2) stories will have a minimum building separation of thirty feet (30').
c. Buffers: A minimum thirty foot (30') buffer shall be required along any boundary that abuts property zoned for single-family development and along 98th Street. (Ord. 2084, 3-9-2015)
d. Landscaping: Street trees will be permitted with the obtainment of a street tree permit. Street tree maintenance will be the responsibility of the property owner and shall not be planted any closer than five feet (5') to a curb. Any tree shall be planted no closer than five feet (5') to a sidewalk. Trees will be maintained to provide a visual clearance of fourteen feet (14') over vehicle travel lanes, eight feet (8') above pedestrian travel lanes, and will be prohibited from being located within the sight triangle of a public street intersection.
e. Guest Parking: One guest parking space will be required for every fifteen (15) residential units. (Ord. 1646, 9-26-2005)
