Section 1207. General Standards and Guidelines.
This section is included in your selections.

A. Applicability. The following shall apply to all property within the Downtown Code Area. If a conflict between the Character Area and these standards and guidelines occurs, the Character Area shall take precedent. Any deviation from these standards or guidelines shall be approved per Section 1224.

B. Planning and Development Department staff have the authority to modify the measurement identified in each Character Area Streetscape Matrix up to 25 percent for the streetscape width and sidewalk width to accommodate existing conditions or a design solution consistent with a pedestrian environment.

C. Height Transition Standards.

For all new development adjacent to lots of a lower height zone, a stepback shall be provided to compensate for disproportionate height disparities.

This additional stepback provides for building separation and circulation of air and light in a dense urban fabric.

1. The stepback shall be a minimum ten feet in width for the length of the building that is adjacent to the lower height zone and shall be measured from the required side or rear yard setback line.

2. When new development is adjacent to multiple lots of differing height zones lower than its own, then the stepback shall mirror the adjacent height zones.

3. A stepback shall not be required in the following circumstances unless modified by Character Area standards:

a. There is a height difference of 20 feet or less between a proposed building and the adjacent height zone.

b. A building is adjacent to a height zone of 65 feet or greater.

c. A street or alley (not designated on Map 1202.F) separates different height zones.

d. The proposed new development is located ten or more feet beyond the required setback line.

D. Height Transition Guidelines. The proposed building should respect the scale of those buildings located on adjacent properties and, where desirable, serve as an orderly transition to a different scale. Building heights with a vastly different scale than those on adjacent parcels should have a transition in scale to reduce and mitigate potential impacts.

E. Shade Standards.

1. All buildings over 5,000 square feet shall provide the following:

a. A minimum of 75 percent of public sidewalks shall be shaded.

b. A minimum of 50 percent of all accessible public and private open space areas shall be shaded, of which 50 percent of the shade shall be provided by trees or trellised vines.

c. Shade calculations shall be based on the summer solstice at 12:00 p.m.

d. Shade cast from a building shall count towards shade calculations.

2. Building additions of more than 500 square feet shall be required to meet the shading requirements.

F. Landscape Standards. Unless there is a conflict with an existing or proposed public utility easement landscaping treatment shall be used for the entire site exclusive of building(s) and structural shade provided in accordance with the following:

1. Thirty percent tree canopy coverage at maturity.

a. Minimum caliper: Two inches.

(1) At installation a minimum 20 percent of all trees shall have a minimum caliper of three inches.

b. A minimum two-foot six-inch radius shall be clear of hardscape around the base of the tree.

2. 50% living vegetation ground coverage.

3. Permanent automatic irrigation system.

G. Landscape and Hardscape Guidelines.

1. A gradual transition of landscaping material should be provide where different oasis and arid landscape themes are proposed among adjacent uses.

2. Any proposed landscape treatment should be compatible with and relate to an established distinctive character in the surrounding area.

3. Alternative paving materials such as permeable pavers, porous concrete or similar materials should be used for on-site hardscaping to reduce urban heat island effect, and to allow natural drainage and filtration.

H. Tree Species Guidelines. The following should be used in accordance with the guidelines established below for the location, type, and care for all trees within Downtown. Any deviation from these guidelines shall be submitted for approval by the Planning and Development Department Landscape Architect or designee, and for properties with HP designation, the Historic Preservation Officer. Tree locations in conflict with overhead power lines may use alternative tree species that are on the approved utility plant list.
