Notes:
1. Accessory structures are generally permitted to a maximum height of forty (40' 0") feet, except that water tanks, silos, granaries, and similar structures or necessary mechanical apparatus may be a maximum height of sixtyfive (65' 0") feet.
2. Flag lots are discouraged and will be reviewed on a casebycase basis.
3. The front yard setback may be reduced when separated sidewalks are utilized. The setback reduction shall not exceed the width of the planter separating the sidewalk and the street. The front yard setback is measured from the front property line, which is typically located at the back of a monolith sidewalk that is contiguous to the street. When a separated sidewalk is used, the property line may either be located at the back of the sidewalk or at the back of the curb. In such instances, the width of the landscaping separating the sidewalk from the curb may be reduced from the required front yard setback. In any instance, however, the driveway shall maintain a minimum depth of twenty (20' 0") feet (fifteen (15' 0") feet for side garages/swing driveways). See the following example figure, which illustrates this concept with the development standards for the RD5 zone:
4. Determined through the design review process.
5. The front setback to covered porch may be reduced to ten (10' 0") feet if a reduced public utility easement (PUE) is approved as part of the subdivision map.
6. In no event shall the rear yard be less than ten (10' 0") feet for one (1) story buildings and fifteen (15' 0") feet for two (2) and three (3) story buildings.
7. Fifteen (15' 0") foot setback for two (2) story; ten (10' 0") foot setback for one (1) story.
8. The side and rear setback for all three (3) or more story multifamily structures (or portions thereof) abutting any singlefamily residential or open space district shall be one hundred (100' 0") feet, measured from the property line of the common boundary.
9. As part of the design review process, the maximum height may be increased to sixty (60' 0") feet.
10. Open space includes active and passive recreation areas, other outdoor amenities, natural open space areas, and all landscaped areas outside of the required landscape corridors along adjoining streets.

2. As part of the design review process, the maximum height may be increased to a height as determined by the designated approving authority; provided, that the intensity of the development is consistent with the General Plan and onsite improvements, including but not limited to architectural articulation, quality, and materials and landscaping, are provided to ensure, as determined by the approval authority, compatibility with the surrounding context and character of the project site.
