2. Setbacks:
a. For any building with a loading area directly facing the residential use, 200-foot setback from the property line on the same side as the loading area contiguous to an existing residential use;
b. For any building without an exposed loading area, 100 foot setback from the property line contiguous to an existing residential use;
c. For temporary outdoor sales displays, 250-foot setback from the property lines contiguous to existing residential use;
d. For trash collection or compaction, 100-foot setback from property line contiguous to an existing residential use;
e. For permanent outdoor sales, 100-foot setback from property line contiguous to an existing residential use;
f. For commercial or industrial, zero setback; and
g. For illustration of a and b, see the commercial design manual.
3. Landscaping and screening:
a. When the large scale retail establishment is contiguous to a residential use, a minimum 60-foot landscape bufferyard, with a minimum of 15 canopy trees per 100 linear feet shall be required. A six-foot decorative masonry wall, which may be placed at the property line, is required unless height and location are otherwise agreed upon by a signed agreement with the contiguous property owners;
b. Landscaping within the parking lot shall conform to the requirements of Section 18.75.040B3;
c. The landscaping plan shall include stormwater harvesting features to be used in the development;
d. Permanent outdoor sales displays, trash collection containers and trash compaction shall be screened from adjacent residential view with opaque materials;
e. The internal walkway from the public sidewalk or right-of-way to the principal customer entrance shall be parallel to a six-foot minimum total width landscaped area using the landscaping standards of the parking lot; see the commercial design manual;
f. Outdoor storage shall be screened from view with opaque materials and be adjacent to the building; and
g. Loading area wall: When required under this Chapter 18.39, a loading area screening wall shall be a fourteen-foot high wall measured on the dock side and shall include an extended cap detail that is a minimum of two-brick courses of eight inches each. See the commercial design manual for illustration.
4. Noise: When the large scale retail establishment is adjacent to an existing residential use, the following noise restrictions shall apply:
a. Deliveries, loading, idling, or similar operations shall not occur between ten p.m. and six a.m. unless the activity occurs within a loading bay or on the street side of the building; and
b. Trash removal or compaction, or similar operations, shall not be allowed between seven p.m. and seven a.m.
5. Noise plan option: To the extent that the proposed development does not meet the applicable development standards contained in Section 18.39.030(C)(2)(a) (exposed loading area), (C)(3)(g) (loading area wall height), (C)(4)(a) (hours of deliveries) and (C)(4)(b) (hours of trash removal and compaction), then a noise plan shall be prepared to evaluate the potential noise impacts in context with the surrounding ambient noise characteristics and shall specify how the proposed development will mitigate noise generation. The required setback for a loading or delivery bay and trash removal or compaction enclosure is a minimum of one hundred feet.
a. Noise level restrictions of the noise plan shall not exceed the following decibel (dB) limits as measured at any adjoining residential property line of the property receiving the sound based on the reference sound pressure and measured with a sound level meter:
1) Large scale retail and shopping center adjacent to residential use: daytime (six a.m. to ten p.m.) sixty-five dB, nighttime (ten p.m. to six a.m.) forty-five dB.
2) Office/commercial use adjacent to residential use: daytime (six a.m. to ten p.m.) sixty-five dB, nighttime (ten p.m. to six a.m.) forty-five dB.
3) Large scale retail and shopping center adjacent to office/commercial use: daytime (six. a.m. to ten p.m.) seventy-five dB, nighttime (not applicable).
b. A noise plan must be prepared and implemented to address all noise including but not limited to the noise resulting from loading and unloading of trucks, dynamic vehicle braking devices, truck waiting/idling, motor vehicle sound amplification equipment, warning devices (i.e. backup alarms), store paging, music systems, mechanical equipment, air-conditioning units, loading and unloading areas, garbage/dumpster/trash compactor and forklift operations. The noise plan shall be prepared in compliance with the commercial design manual.
6. Odor: When the large scale retail establishment is adjacent to an existing residential use, an odor plan shall be required to evaluate the potential odor emissions from food preparation or chemicals that may be offensive or that may create a nuisance beyond the property line. The odor plan shall be prepared in compliance with the commercial design manual.
7. Light: All outdoor lighting shall be in accordance with the county outdoor lighting code (Title 15).
8. Commercial Design Manual: The commercial design manual, adopted by resolution of the board of supervisors, shall provide guidelines and procedures for implementation of the standards of Chapter 18.39.
9. Submittal requirements for building design: Submittals shall be made through the subdivision coordination office and shall include the following:
a. Illustrations depicting two traverse sections of the entire site (generally north-south and east-west) that include the height and relationships of structures and that are drawn at the same scale as the development plan; and
b. Identification and description of all design features on the traverse sections, including those listed in the commercial design manual.
D. Additional Standards.
1. An economic impact statement shall be submitted with the site plan which assesses the impact the cost of emergency services, and the ratio of existing and potential commercial development available to the target population.
2. Food and beverage sales areas shall not in total exceed ten percent of the general merchandise and retail sales areas of the establishment.
