A. The number of dwelling units per acre allowable on the gross usable area of a residential PUD shall be determined by the planning commission. However, in no event may the number of dwelling units per acre exceed four.

B. A minimum of thirty (30) percent of the site shall be reserved as usable open space. At least one-half (1/2) of such usable open space shall be contiguous, and no portion of the required open space may be less than two thousand (2,000) square feet in area or less than thirty (30) feet in its smallest dimension. A minimum of twelve (12) percent and a maximum of fifty (50) percent of required open space shall consist of yards which shall be reserved for the residents of individual dwellings. In multistory buildings, balconies or decks may be used in lieu of yards; provided, that the total area of all balconies or decks and yards is not less than the total yard area that would otherwise be required.

C. Permitted uses shall be limited to residential and accessory uses, convenience establishments and personal or professional services. A residential PUD may not include the storage or use of mobile homes, freezer vans, Quonset huts or similar structures. Any nonresidential use must be specifically authorized as to its exact location, type and size. In no event shall the floor area of nonresidential uses exceed ten (10) percent of the total internal floor area of the PUD.

D. Any nonresidential use permitted in a residential PUD shall be compatible with the residential nature of the development. Parking areas which are intended to serve nonresidential uses shall be separated from those designed to serve residential areas. Unless commercial and residential uses are combined within a single structure, commercial uses shall be separated from dwelling units by a heavily landscaped buffer zone having a minimum width of thirty (30) feet.

E. Pedestrian paths shall connect residential uses and nonresidential uses within a residential PUD.

F. Buffer landscaping shall be planted along each boundary of the planned unit development adjoining a nonresidential district or a right-of-way designated for collector or greater capacity.

G. Any two (2) adjacent buildings within a PUD shall be separated from each other by a distance equal to one-half the height of the taller building.

H. Streams shall, except for necessary bridges and crossings, be separated from streets, parking areas and structures with a landscaped buffer zone having a minimum width of fifty (50) feet.

I. Walls and ceiling-floor assemblies which are common to any two (2) dwellings shall have a minimum STC acoustic rating of fifty-five (55) and a minimum fire rating of one (1) hour.

J. Each required parking space for residential uses shall be provided with an electrical outlet.

K. Any PUD which will involve the formation of a horizontal property regime under the terms of AS 34.07.030, et seq., or any mandatory homeowners’ or similar association must submit for review by the commission the articles of incorporation and bylaws of any such association prior to the sale of any property subject to the association. The planning commission may require any provisions necessary to ensure that the provisions and intent of this title are met. [Ord. 01-05 § 8.]
