A. Base Densities. The density of the development shall not exceed the density established by this section. The density shall be computed by dividing the total number of dwelling units by the acreage of the project, including land dedicated to the public. Fractional portions of the final answer, after bonus point calculations, shall not apply towards the total density. Accessory residential units and duplexes are not required to meet the density requirements of this chapter in accordance with sections and

1. The base density, for purposes of determining density bonuses allowed under this section, for developments other than cottage housing, is as provided in Table

b. Duplexes. Duplexes are permitted in a cottage housing development if the total number of dwellings in the development is at or below the maximum cottage housing development density in subsection, above.

3. Common Open Space Required. All developments subject to this section with a base density of ten units or greater shall be required to provide common open space pursuant to section

B. Density Bonus Point Calculations. The permitted base density shall be increased by the percentage gained through density bonus points. In no case shall the density exceed that allowed under the Comprehensive Plan. The maximum density bonus permitted shall be 60 percent (base density x 1.6), pursuant to the following criteria:

1. Conservation Housing. A maximum 15 percent bonus is allowed. One hundred percent of the homes or residential units approved for development, after bonus point calculations, shall meet the minimum requirements for certification as an Earth Advantage home, as approved by the Ashland Conservation Division under the City’s Earth Advantage program as adopted by Resolution 2006-06.

2. Common Open Space. A maximum ten percent bonus is allowed, pursuant to the following:

a. Purpose. Common open spaces may be provided in the form of natural areas, wetlands, playgrounds, active or passive recreational areas, and similar areas in common ownership. However, for the purposes of awarding density bonus points, the Planning Commission shall consider whether or not the common open space is a significant amenity to project residents, and whether project residents will use or enjoy the common open space on a day-to-day basis.

b. Standard. Developments with fewer than ten units that provide more than two percent of the project area for common open space, or for developments of ten units or greater that provide more than five percent common open space, a one percent bonus shall be awarded for each one percent of the total project area in common open space in excess of any common open space required by section and this chapter. The common open space shall meet the standards in section

3. Affordable Housing. A maximum bonus of 35 percent is allowed. Developments shall receive a density bonus of two units for each affordable housing unit provided. Affordable housing bonus shall be for residential units that are guaranteed affordable in accordance with the standards of section, Affordable Housing Standards.
