F. Design Standards.

1. Adeline Corridor Specific Plan. New buildings and additions shall be reviewed for conformance to the design guidelines in the Adeline Corridor Specific Plan.

2. Ground Floor Frontages.

(a) All New Buildings. Except as set forth below, ground floor frontages of all new buildings are subject to the following design standards:

i. Blank walls along the ground floor shall be less than 30 feet in length along sidewalks, pedestrian paths, or open space.

ii. Ground floors shall have a minimum floor to floor height of 12 feet.

iii. Facades shall provide at least 30 percent transparency between 3 and 10 feet above grade (doors and transparent windows) to allow maximum visual interaction between the sidewalk areas and building interiors. Dark or mirrored glass will not satisfy this requirement.

iv. Window glazing shall provide a high degree of light transmittance and be non-reflective.

(b) Active Commercial Areas. Ground floor frontages in areas identified as Active Commercial in Table 23.204-42 shall meet the requirements of 23.204.150(F)(2)(a) except:

i. Ground floors shall have a minimum floor to floor height of 15 feet and a minimum floor to ceiling height of 12 feet.

ii. Facades shall provide at least 75 percent transparency between 3 and 10 feet above grade (doors and transparent windows) to allow maximum visual interaction between sidewalk areas and the interior. Dark or mirrored glass will not satisfy this requirement.

(c) Commercial Use Areas. Ground floor frontages in areas identified as commercial in Table 23.204-42 shall meet the requirements of 23.204.150(F)(2)(a) except:

i. Ground floors shall have a minimum floor to floor height of 15 feet and a minimum floor to ceiling height of 12 feet.

ii. Facades shall provide at least 65% transparency between 3 and 10 feet above grade (doors and transparent windows) to allow maximum visual interaction between sidewalk areas and the interior of office spaces. Dark or mirrored glass will not satisfy this requirement.

(d) Exceptions. The Design Review Committee or Design Review staff may grant exceptions to the blank wall and transparency requirements.

G. Permit Findings.

1. General. To approve any AUP or Use Permit for a project in the C-AC district, the review authority must make the findings in Section 23.406.040--Use Permits and find that the proposed use or structure:

(a) Is consistent with the purpose of the district;

(b) Is compatible in design and character with the district and the adjacent residential neighborhoods;

(c) Encourages utilization of public transit and off-street parking facilities in the area of the proposed building; and

(d) Complies with the Adeline Corridor Specific Plan’s adopted Mitigation Monitoring and Reporting Program (MMRP).

2. New Residential Development. In addition to the findings above, the ZAB shall find, for each Use Permit for new residential development, that the proposed use or structure facilitates the construction of affordable housing as defined by the U.S. Department of Housing and Urban Development (HUD) Guidelines.

3. Office Uses.

(a) To approve an AUP for an office use over 2,500 square feet or over 50 feet wide on the ground floor of an Active Commercial area, the Zoning Officer must find that the use supports the development of a strong retail commercial, pedestrian-oriented environment.

(b) Factors the Zoning Officer should consider shall include, but are not limited to, pedestrian activity that is expected to be generated at the site, the placement of store entrances relative to the street and the parking lots, and the size and prominence of display windows and areas facing the sidewalk.

4. All-Electric Buildings. An AUP may be granted to reduce useable open space requirements if shown to be necessary to build an all-electric building. To approve an AUP, the Zoning Officer must find that:

(a) No other placement of the features to support construction of an all-electric building, including solar photovoltaic (PV) energy systems and water tanks for heat pump water heating, on the property is possible; and

(b) Placement of the features to support construction of an all-electric building elsewhere on the property is not financially feasible. (Ord. 7898-NS § 12, 2024; Ord. 7890-NS §§ 27--32, 2023: Ord. 7787-NS § 2 (Exh. A), 2021)
