To allow flexibility in design and creative site planning, while providing for the orderly development of the county. A performance based development (PBD) is to allow for the use of lot clustering in order to preserve open space, encourage the creation of suitable buffers between differing types of development, facilitate the residential densities allowed by the zone, provide for increased efficiency in the layout of the streets, utilities and other public improvements and to encourage the use of low-impact development techniques and other creative designs for the development of land.
Standard regulations that may be modified through the use of a PBD include:
A. Lot size.
B. Lot width and depth.
C. Structure height (only within designated urban growth areas).
D. Setbacks (front, side and rear yards).
Minimum and maximum densities and allowed uses authorized by the zone shall not be subject to modification through the use of a PBD.
(Ord. 534 (2016) § 7(5) (App. E) (part), 2016)
17.450.020 Authority.
The hearing examiner shall have the authority to recommend approval, approval with conditions, disapproval, or revoke performance based developments, subject to the provisions of this section. Changes in use of site area, or alteration of structures or uses classified as residential and commercial performance based developments, and existing prior to the effective date of this title, shall conform to all regulations pertaining to performance based developments. An application for PBD shall be accompanied by an application for subdivision, when applicable.

B. Common Open Space. No open area may be accepted as common open space within a performance based development, unless it meets the following requirements:
1. The location, shape, size, and character of the common open space is suitable for the performance based development, however in no case shall the common open space be less than fifteen percent of the gross acreage of the subject property(s). No area shall be calculated as common open space if less than five hundred square feet in size, except if the area provides a reasonable functional or aesthetic benefit to the residents of the PBD;
2. The common open space is suitable for use as an amenity or recreational purpose, provided the use authorized is appropriate to the scale and character of the planned density, topography, and the number and type of dwellings provided;
3. Common open space may be improved for its intended use. Common open space containing critical areas may be enhanced consistent with the requirements of Title 19, Critical Areas Ordinance. Vegetation-based LID BMPs are permitted within common open space areas. The buildings, structures, and improvements to be permitted in the common open space are those appropriate to the uses which are authorized for the common open space; and
4. Land shown in the final development plan as common open space, and the landscaping and/or planting contained therein, shall be permanently maintained by and conveyed to one of the following:
a. An association of owners formed and continued for the purpose of maintaining the common open space. The association shall be created as an association of owners under the laws of the state of Washington and shall adopt articles of incorporation of association and bylaws. The association shall adopt, in a form acceptable to the prosecuting attorney, covenants and restrictions on the open space providing for the continuing care of the area. No common open space may be altered or put to a change in use in a way inconsistent with the final development plan unless the final development plan is first amended. No change of use or alteration shall be considered as a waiver of any covenants limiting the use of the common open space, and all rights to enhance these covenants against any use permitted are expressly reserved;
b. A public agency which agrees to maintain the common open space and any buildings, structures, or other improvements which have been placed on it; or
c. A private nonprofit conservation trust or similar entity with a demonstrated capability to carry out the necessary duties and approved by the county.
