(A) The following requirements and minimum area standards shall be met. No improvements shall be placed on such lands unless the lands to be so used or improved shall meet the following minimum area and dimensional requirements. Densities are predicated upon the availability of public water, storm sewer, and sanitary sewer service; without the service, densities shall be limited to one dwelling unit or structure per ten acres. The following table shall be used to compute the minimum lot area exclusive of street rights-of-way, in square feet, and such computation shall be subject to the following; ponding area or similar unbuildable areas shall not comprise more than 10% of the total site area.
(1) Table of minimum area standards and requirements. The dimensions shall be measured in feet unless otherwise specified.

(2) Landscaped islands within parking lots shall be provided for all parking lots in the neighborhood center. The total area of the islands shall be at least 2% of the parking lot area, except that no island shall be less than the size of a standard parking stall. In addition to the required tree planting in landscape islands, ground cover within the island shall also be installed.
(3) Maximum impervious surface, see § 155.350.
(4) Screening, see § 155.348.
(5) Landscaping, see § 155.349.
(7) Building materials, see § 155.346.
(8) Off-street loading areas, see § 155.354.
(9) Where private balconies for individual dwelling units in multiple-residential buildings are included, they shall be incorporated into the overall building design so as to provide architectural relief through the use of privacy walls beneath protruding dormers or some similar treatment.
(10) Roofs in multiple-residential buildings shall have a minimum pitch of one to three.
(11) Building elevations along public streets. In multiple-residential buildings, no more than 50% of the length of a building elevation which faces a public street can be used for garage doors.
(B) The following requirements are in addition to those in division (A). Where there may be a conflict, those requirements under this division shall prevail:
(1) Front setbacks prevailing. Where adjoining structures existing at the time of adoption of this article have a greater setback than that required by this article, the front setback of a new structure shall conform to the prevailing setback in the immediate vicinity. The Building Inspector shall determine the necessary front yard setback in such cases. In no case shall a building be required to be set back more than 50 feet.
(2) Side and rear setbacks, party walls. Buildings may be excluded from side and rear setback requirements if party walls are used and if the adjacent buildings are constructed as an integral structure. This shall not permit structures closer to residential districts, however, than required under division (A).
(3) Density bonus. Certain design and construction features serve to reduce the real and perceived impacts of crowding, prevalent in multiple- residential dwelling units and building complexes. These features enhance individual unit privacy, offer an improved outdoor environment, and foster a sense of pride and commitment to its residents. These traits contribute to neighborhood stability and positive social relationships which are found to be beneficial to the community as a whole. To the extent that these features are incorporated, the maximum density permitted in each of the zoning districts shall be increased in accordance with the following, except that the increased density shall not exceed that listed under “with bonus” as stipulated in subsection (1) above. Where only a portion of the dwellings or buildings are provided with these features, the increase in density shall be prorated.
(a) Common open space. This equals 1.0 units/acre. This bonus shall be granted when multiple-residential buildings in a complex are arranged in a manner which creates significant open space between them. In order to be eligible, the open space so created must have a minimum area of two times the lot coverage of the buildings which face the space, be configured in a regular shape, be recognized as a defined common or sheltered area, and be designed or contain features which encourage social interaction among the residents of the complex.
(b) Private outdoor space. This equals 0.50 units/acre. This bonus shall be granted when multiple-residential buildings are designed so that each dwelling unit is provided with a contiguous private outdoor space. In order to be eligible, the private spaces must be designed to be screened or sheltered such that its occupants are not visible from any other dwelling unit, other private open space, or any passer- by on adjacent private or public property.
(c) Sound suppression. This equals 1.50 units/acre. This bonus shall be granted when multiple-residential buildings are constructed with upgraded sound suppression materials in the walls, ceilings and floors which separate individual dwelling units. In order to be eligible, the STC rating must be increased by ten from that specified as the minimum in the Minnesota State Building Code.
(d) Basements. This equals 0.25 units/acre. This bonus shall be granted when multiple-residential buildings are constructed with a full basement under each dwelling unit rather than a crawl space or slab-on-grade. In order to be eligible, the basement must exist under the entire ground floor area, excepting therefrom any garage area.
(e) Oversize garages. This equals 0.50 unit/acre. This bonus shall be granted when multiple-residential buildings are constructed with oversize garage areas for storage purposes. In order to be eligible, townhouse garages must each be a minimum of 550 square feet. Apartment garages must each be a minimum of 250 square feet or, in the alternative, each apartment dwelling unit must be provided with a locking storage locker of at least 50 square feet.
(f) Private amenities. This equals 1.0 units/acre. This bonus shall be granted when multiple-residential buildings are constructed with upgraded living amenities within each dwelling unit. In order to be eligible, each dwelling unit must be provided with a functional fireplace (0.50 units/acre) or 1¾ bathrooms (0.50 units/acre).
