A. Purpose: To ensure superior design and public benefit are incorporated into developments requesting waivers from base district standards beyond lot size or road widths.
B. PBPUD Developable Residential Density: Total acreage, including all hazard lands, calculated according to the density of the underlying zoning district.
C. Public Benefit And Superior Design: Public benefit is an essential component of superior design. To meet the superior design standard, PBPUD applications shall incorporate all primary public benefits listed in subsection C1 of this section, and two (2) secondary public benefits listed under subsection C2 of this section.
1. Primary public benefits:
a. Community housing of at least ten percent (10%) of the units proposed or if in the ACI twenty percent (20%). Units shall be in addition to the established base density. Unless the board determines that an alternative community housing approach would better serve the objective of creating community housing, housing shall be provided under Blaine County housing authority guidelines as amended through in-lieu payment, on site construction, off site construction, transfer of equivalent value land or existing housing stock;
b. Reduced impacts on road systems through the provision of bike and pedestrian friendly infrastructure such as bus stops, bike paths and bike designated road sections; or a substitute financial contribution;
c. Road impact mitigation as quantified using the Blaine County road mitigation fee formula.
2. Secondary public benefits:
a. Recreational amenities accessible and affordable to the general public;
b. The maximum structural square footage per lot shall be limited to four thousand (4,000) square feet, including accessory dwelling units, garages or other accessory uses. Said floor area shall be the total of all conditioned floor area as measured from the interior face of the exterior walls, excluding basements;
c. Federal EPA Energy Star or leadership in energy and environmental design (LEED) basic certification for all structures; residential or commercial;
d. Other design elements based upon the specific attributes of the property, which serve to promote the public benefit goals of this section and provide a significant public benefit exceeding the requirements of other applicable review standards.
D. PBPUD Density Bonus Requirements: The board may authorize PBPUD density bonuses up to the limits specified in the zoning district. The available number of bonus units shall be calculated according to the eligible acreage in the underlying zoning district (not the total acreage). No density bonuses shall be granted in any R-10 PUD or A-20 PUD located in a TDR receiving area.
The following shall be justification for such bonuses:
1. Accomplishing public purposes beneficial to the entire county, beyond what is required under subsections C1 and C2 of this section. (Ord. 2009-06, 8-26-2009)
