This section is included in your selections.

A. The following may project from a building into a required setback; provided, that such projection does not interfere with required utility easements or sight distance requirements pursuant to city design and construction standards:

1. Fireplace structures, bay windows, garden windows, enclosed stair landings, closets, framed fireplace shafts, wireless communications facilities or similar projections not wider than eight feet measured in the general direction of the wall of which it is a part: 18 inches into any setback; provided, that such projection does not interfere with required utilities easements or sight distance requirements pursuant to city design and construction standards;

2. Porches and Platforms.

a. Uncovered porches and platforms which do not extend above the floor level of the first floor: 18 inches into side setbacks and six feet into the front setback and rear setback; provided, that they may extend three feet into the side setback when they do not exceed 18 inches in height above the finished grade;

b. Covered but unenclosed porches and platforms which do not extend above the floor level of the first floor and which are no wider than 50 percent of the building’s frontage: five feet into the front setback;

3. Planting boxes or masonry planter not exceeding 42 inches in height may intrude into any setback;

4. Eaves shall not protrude more than 24 inches into any minimum required setback;

5. Awnings, canopies, marquees and similar structures designed to primarily protect pedestrians from the weather elements. They shall be attached to and supported entirely by the building. The maximum projection shall be seven feet from the building. The projection, if approved by the city, must comply with the International Building Code (IBC) and International Fire Code (IFC), and an approved right-of-way use permit subject to the requirements of Chapter 12.60 ACC.

B. Special Front Setback Depth. If buildings existing on July 6, 1964, occupy 50 percent or more of the frontage in any block, and are on one side of the street, then the depth of the front setback required by this title shall be disregarded on that side of the street in such block, and in lieu thereof the depth of front setback required on each lot therein shall be not less than the average depth of the front setbacks existing on July 6, 1964. This shall apply to residentially zoned property only.

C. Lots with Significant Slopes. To encourage the preservation of natural features on lots with significant slopes, platted residential lots with an average slope of 15 percent or more may reduce the front setback by up to 20 percent; provided, however, that all structures must comply with applicable sight distance triangle requirements of the city design and construction standards. This provision shall only apply to lots developed for a single-family residence but shall not apply to property zoned RC (residential conservancy).

For the purposes of this section, the average slope shall be measured by taking the difference between the average elevations of the rear and the front lot lines. This provision is not intended to waive any other requirements of geotechnical reports or studies that may be necessary to ensure the suitability of a lot for development.

Development under this provision may also implement the setback exemptions identified in subsections (A)(1) through (A)(5) of this section. (Ord. 6245 § 15, 2009.)
