§ 20.61.045 Density bonus.
A.
Bonus densities are intended to provide incentives to encourage the development of additional public amenities or to preserve valuable natural or cultural resources and features. It is the intention of this section to allow bonus densities where an applicant proposes design attributes providing public benefits in addition to those required by local, state, or federal land use or environmental regulations. The allocation of bonus densities will be based upon a comprehensive review of the entire project. In order to satisfy any of the bonus density criteria specified in this section, the design attributes must be considered in the public interest and worthy of bonus density. Bonus densities will not be allowed for site design proposals which merely reflect mandatory requirements of local, state, and federal codes or regulations.
B.
The site plan review committee may approve an increase in dwelling unit density based upon the following criteria:
1.
Innovative Residential Development. Up to a maximum of a ten percent density bonus may be awarded if a more efficient use of land, energy, and resources and a more livable development can be achieved through innovative variation of residential types, configuration, placement, and density.
a.
Such flexibility can be achieved while safeguarding the public interest by review of the proposed planned unit development plan which shows the type and placement of residential structures.
b.
It is intended that innovative residential developments encourage imaginative design to achieve bonus densities. Therefore, incentives and flexibility may be allowed such as rear alley loading housing, various home sizes, architectural features, etc. The city may approve the use of these tools as provided in this section as deemed reasonable and warranted by the excellence of the resulting design and its benefits to the community. Innovative architectural exteriors and interiors are strongly encouraged.
2.
Additional Public Recreation Facilities. Up to a maximum of a ten percent density bonus may be awarded for the addition of significant recreational areas that are designed in such a way as to encourage outdoor activities within the common open space; such features include, but are not limited to, playgrounds, ballfields, pickleball courts, basketball/volleyball courts, skate parks, swimming pools, tennis courts, bike or pedestrian path systems, community gardens, or a community building.
a.
To qualify, the improvements shall be maintained by a homeowners' association and be written into its bylaws to be maintained in perpetuity or shall be dedicated to the city.
b.
Recreational areas and features shall serve the residents in the development and the general public and shall be designed as an amenity for the greatest number of people.
3.
Mixed Use Development (Commercial and Residential). Up to a maximum of a ten percent density bonus may be awarded for the addition of mixed use buildings to the project. Such buildings may include a convenience store, espresso stand, day care facility, multiple small retail spaces, beauty/barber shops, or similar personal services.
a.
To qualify, at least ten percent of the net land area must be used for commercial purposes.
b.
Mixed use buildings shall be designed and used to meet the needs of the residents within the greater neighborhood area.
c.
Commercial uses in a residential area shall be limited in scope, size, etc. to prevent rezoning of the property. Commercial uses shall not exceed thirty percent of the overall land area and fifty percent of the residential structures planned for the development must be completed prior to issuance of a building permit for a commercial use.
4.
Additional Preservation of Open Space and Natural, Historical and Cultural Features. Up to a maximum of a five percent density bonus may be awarded for the substantial retention of natural groundcover, bushes and trees; minimum disturbance of wildlife habitat; preservation of unique historical or cultural features; and preservation of air, sunlight and scenic resources.
a.
To qualify, the open space area shall be over one-half acre in size and be deeded as open space in perpetuity.
b.
An additional five percent density bonus may be awarded for dedication to the city of land within the city's potential park or open space areas and corridors as designated in the comprehensive plan and as shown on the land use map.
5.
Additional Landscaping to the Outer Edge of the On-Site Drainage Retention Facility. Up to a three percent density bonus may be awarded for additional landscaping to the outer edge of the on-site drainage retention facility.
C.
The maximum density bonuses the site plan committee may approve are: (1) fifteen percent in the R:20 zoning district; (2) twenty percent in the R:8, R:15, and LBD zoning districts; and (3) twenty-five percent in the R:2 and R:4 zoning districts. Bonus density shall be rounded down to the nearest whole number.
