CHAPTER 33.405
ALTERNATIVE DESIGN DENSITY OVERLAY ZONE

33.405.010 Purpose
The purpose of the Alternative Design Density Overlay Zone is to focus development on vacant sites, preserve existing housing and encourage new development that is compatible with and supportive of the positive qualities of residential neighborhoods. The concept for the zone is to allow increased density for development that meets additional design compatibility requirements.

33.405.020 Short Name and Map Symbol
The Alternative Design Density Overlay Zone is referred to as the ADD zone, and is shown on the Official Zoning Maps with the letter “a” map symbol.

33.405.030 Applying the Alternative Design Density Overlay Zone
The Alternative Design Density Overlay Zone may be established or removed as the result of an area planning study, reviewed through the legislative procedure. Establishment or removal of the Alternative Design Density Zone through a quasi-judicial procedure is prohibited. The ADD zone has no effect on projects in RH, RX, IR, C, E, or I zones. When property is rezoned to one of these zoning designations from a zone that is accompanied by the "a," the ADD zone will be deleted from the Official Zoning Map.

33.405.050 Bonus Density for Design Review
A. Purpose. This section is intended to encourage the provision of well designed housing that is attractive and compatible with an area’s established character. Increased density through this bonus provision is allowed in areas zoned for multi-dwelling development. These areas include those within the ADD zone that have a base zone of R1, R2, or R3.

B. Where the bonus may apply. The bonus density for design review is applicable in areas within the ADD zone that are zoned R3, R2, or R1. It is not, however, allowed on sites in design or historic design zones.

C. Bonus density. Fifty percent more dwelling units than allowed by the base zone is granted for projects that voluntarily go through a Type III design review process. If a land division is required or requested, the design review process must be concurrent with the land division. Design review must be approved in order for the land division to be approved. The development will be judged against the Community Design Guidelines.

D. Relationship to other density bonuses. Development taking advantage of the provisions of this section is not eligible for density bonus allowed by other sections of the code, including Section 33.120.265, Amenity Bonuses.

33.405.060 Attached Houses on Vacant Lots in the R5 Zone.
A. Purpose. The increased density permitted by this section encourages infill development in areas that are generally well served by existing public services. The increase allows the area to absorb additional growth without creating market pressure that might lead to the early removal of existing sound housing. The increased density will lower the cost of housing while increasing opportunities for owner-occupied housing. Required design review of new development ensures that the new housing will make a positive contribution to the neighborhood’s character.

B. Attached houses. Attached houses are allowed in the R5 zone if all of the following are met. Adjustments to this section are prohibited:

1.The proposed attached housing development will be on a lot or lot of record that was created at least five years ago;

2. There has not been a dwelling unit on the lot or lot of record for at least five years;

3. The density requirements of Chapter 33.611 must be met, and each attached house must be on a lot that meets the lot dimension standards of Chapter 33.611;

4. Attached houses must meet the following development standards:
a. Height and front setback standards. Attached houses must meet the height and front setback standards of the R5 zone; and
b. All other development standards. The attached house must meet all other development standards for attached housing projects in the R2.5 zone;

5. Design review required:
a. Generally. Attached residential development must be approved through design review or meet the Community Design Standards in Chapter 33.218, as set out in Section 33.405.090, Design Review and Community Design Standards, below; and
b. Exception. If the site is a Historic or Conservation Landmark, or in a Historic or Conservation District, it is subject to the regulations for historic design review as set out in Chapter 33.445, Historic Resource Protection Overlay Zone.
c. Land Division. If the proposal requires, or the applicant requests, a land division, the application for the land division must show how the Community Design Standards are met. If the Community Design Standards cannot be met or the applicant chooses not to meet the Community Design Standards, design review is required. When design review is required, the design review process must be concurrent with the land division. The Community Design Standards must be met or design review must be approved in order for the land division to be approved.
d. Changes to a design approved concurrently with a land division. If the design of the proposed development was reviewed concurrently with the land division through design review, changes to the design of the proposed development after final plat approval must be reviewed through design review. If the proposed development met the Community Design Standards concurrently with the land division, changes to the design of the proposal after final plat approval must continue to meet the Community Design Standards, or must be reviewed through design review. Concurrent land division review is not required to change the design of the proposed development after final plat approval.
