§ 22.10

A.

The provisions of this Chapter address the details of site planning, project design, and the ongoing conduct/operation of land uses. These standards are intended to ensure that all development produces an environment of stable and desirable character, and is harmonious with existing and future development, and protects the use and enjoyment of neighboring properties, consistent with the General Plan.

[22.04.010]

B.

The operational standards of this Chapter are established to protect residents from the adverse effects of excessive or objectionable emissions of noise or air contaminants that may be generated by land uses, activities, processes or equipment.

[22.06.010]

A.

The standards of this Chapter apply to all new land uses required to have a land use permit in compliance with this Title, except:

1.

Where the standards of Chapters 22.14 (Combining Designation Standards), or Article 4 (Standards for Specific Land Uses) conflict with the provisions of this Chapter, the provisions of Chapters 22.14 and Article 4 prevail;

2.

Where planning area standards Article 9 (Community Planning Standards) conflict with the standards of this Chapter, the planning area standards prevail.

B.

A use existing on the effective date of this Title, or on the date of a subsequent amendment to this Title that applies more restrictive operational standards to the use, shall not be required to change their operations to comply with the provisions of Sections 22.10.030 (Air Quality), 22.10.050 (Explosives Storage), 22.10.070 (Flammable and Combustible Liquids Storage), 22.10.120 (Noise), 22.10.170 (Vibration), and 22.10.180 (Water Quality), unless a modification of the use is proposed that requires a permit. However, in no case shall existing operations be changed to result in a greater degree of noncompliance with these standards than existed on the effective date of this Title or amendment.

Nothing in this Chapter shall preclude the initiation of revocation, abatement or legal action against an existing use operated in violation of Sections 22.10.120 (Noise) or 22.10.170 (Vibration) or operated in manner that creates a public nuisance.

[Amended 1994, Ord. 2696] [22.04.012, 22.06.020]

A.

Air Pollution Control District (APCD) Review.

1.

Purpose. This Subsection establishes a procedure for the notification of the County APCD when a new land use is proposed to include equipment or activities that involve combustion, or the storage or use of hydrocarbons or other air contaminants.

2.

Applicability. These provisions apply to any project for which a discretionary land use permit is required by this Title, except business licenses consistent with the most current guidelines of the Air Pollution Control District.

3.

Review procedure. A copy of any application shall be forwarded to the Air Pollution Control District for review upon receipt by the Department. This referral is intended to enable the APCD to:

a.

Determine if the use proposed is required by the rules and regulations of the APCD to obtain an authority to construct or permit to operate;

b.

Determine if the proposed project exceeds the district's significance thresholds for significant air quality impacts from land use projects, and if mitigations are required.

c.

Contact and advise the applicant on applicable permit and air quality requirements, and to advise the Department of any APCD permit requirements.

(1)

In the case of a Zoning Clearance application, within 10 business days of application transmittal;

(2)

In the case of Minor Use Permit or Conditional Use Permit applications, notification of permit requirements, or special concerns or recommendations to be forwarded to the Review Authority shall be returned to the Department no later than 10 days before the public hearing on the application.

4.

Building Permit issuance. When the APCD has notified the Department that authority to construct is required, the applicant is to provide the Department with evidence of approval of an authority to construct prior to issuance of a building permit. In the event that the APCD has not notified the Department of APCD permit requirements within 10 business days of application transmittal, the lack of notification shall not cause additional delay in permit issuance by the Department; however, permit issuance under such circumstances shall not exempt any person from the necessity of obtaining APCD permits if required.

5.

Certificate of Occupancy. In cases where an APCD permit to operate is required, no certificate of occupancy shall be issued until the applicant has provided the Department with evidence of permit approval.

B.

Odors. Any non-agricultural land use conducted in, or within one-half mile of an urban or village reserve line shall be operated so as not to emit matter causing noxious odors which are perceptible at the points of determination identified in the following table.

At or beyond the boundary of the Industrial category.

Industrial

B.

In the event archeological resources are found to include human remains, or in any other case when human remains are discovered during construction, the County Coroner shall be notified in addition to the Department so proper disposition may be accomplished.

[22.05.140]

The storage of explosives is allowed only for the purpose of sales by a licensed vendor, or where the explosives will be used on the same site as the storage facility, as provided in this Section.

A.

Applicability. The standards of this Section apply in addition to all applicable state and federal standards, including any regulations administered by the County Health Department, Fire Department, Sheriff's Office, Agricultural Commissioner, and Air Pollution Control District. If any standards of this Chapter conflict with regulations administered by other federal, state, or county agencies, the most restrictive standards apply.

B.

Permit requirement. Conditional Use Permit approval within an urban or village reserve line; Minor Use Permit approval in rural areas. Separate land use permit approval is not required where the principal use of the site has been authorized through Conditional Use Permit approval, or in the case of a surface mining operation, where the operation has been authorized by an approved reclamation plan. This permit requirement is in addition to the permit required by the County Sheriff.

C.

Location. Explosives storage is allowed only in the Agriculture, Rural Lands or Industrial land use category, or areas included within an Energy and Extractive Resource (EX) combining designation. A land use permit application that proposes explosives storage may be approved only where the Review Authority finds the proposed site is within an area that is open in character and essentially free of development.

D.

Setbacks. Explosives storage shall not be located closer than 1,000 feet from any property line, except that storage in Class II magazines, as authorized in State law, shall not be located closer than 400 feet from any property line; provided that where the current edition of the Uniform Fire Code adopted by the County would require a greater setback than required by this Section, the greater setback shall apply.

E.

1.

Permit requirements. For developments that choose to comply with the provisions of Subsections B.2.c through B.2.i, Zoning Clearance is required for residential structures, residential accessory buildings and residential access roads to review conformance with Subsections B.2.c through B.2.i. Projects that do not choose to comply with Subsections B.2.c through B.2.i are required to apply for a Minor Use Permit, or a Conditional Use Permit if otherwise required by Section 22.06.030 (Allowable Land Uses and Permit Requirements).

Within the Highway corridors (limited to the first 300 feet) shown in Figures 104-5 through 104-16, Zoning Clearance approval (with a confirming site visit) is also required for agricultural accessory buildings larger than 600 square feet, individually or cumulatively, and having one or more of the following: a roof pitch of less than 3:12, unarticulated wall surfaces and/or service entrances facing the highway.

If the Zoning Clearance application cannot be approved in compliance with Subsections H.2.c through H.2.i, the applicant may choose to convert the application to a Minor Use Permit application, with the applicant paying the difference in application fees.

2.

Zoning Clearance requirements. Zoning Clearance applications for sites within or partially within the highway corridors shown in Figures 10-4 through 10-15 shall comply with the following, in addition to other applicable standards:

a.

Site visit required. The Zoning Clearance application shall be subject to two site visits; one during the time of application review to confirm that conditions on the site correspond to information provided in the application, and the other prior to final building inspection to confirm that the building and site improvements agree with the approved plan. (Planting of required landscaping improvements may be delayed up to 90 days after final building inspection when installation is guaranteed by bond.)

b.

Exemption. An exemption from Subsections H.2.c through H.2.i may be granted if documentation is provided that the project will not be visible from the applicable highway corridor. Such documentation shall at minimum provide topographic contours (referenced to sea level), and building elevations with preliminary grading and building plans. A visual analysis of the project's location may be useful to facilitate a decision.

If conformance with these standards would unavoidably impact a biological habitat, the Director may waive the applicable standard.

c.

Highway setback. Where possible, residential buildings, residential accessory structures, and agricultural accessory structures larger than 600 square feet with the features described in Subsection H.1, shall be set back 100 feet from the applicable highway right-of-way as shown in Figure 10-16. If there is no feasible development area outside this setback, the project shall be located on the rear half of the property and shall provide a landscaping screen of fast, or moderately fast, growing plant material to provide 80 percent coverage at plant maturity. A landscaping plan per Chapter 22.16 shall be provided with the Building Permit application.

Figure 10-21: Landscaping

i.

Biological habitats. Development shall be designed and located to minimize adverse impacts to important biological resources in conforming with these standards. If there is a conflict between biological resources and these standards, protecting the biological resources takes precedence.

Discretionary permit requirements. Minor Use Permit approval is required for projects that are unable to meet the requirements for a Zoning Clearance as specified in Subsections B.2.c through B.2.h above. Minor Use Permit and any Conditional Use Permit applications that may otherwise be required by this Title shall include a visual analysis that is prepared by a registered architect, landscape architect or other qualified individual acceptable to the Director. The visual analysis shall be utilized to determine compliance with the intent of standards B.2.c through B.2.h and the following:

a.

Locate development, including access roads, in the least visible portion of the site consistent with the protection of other resources, as viewed from the applicable highway corridor or road. Use existing vegetation and topographic features to screen development from view as much as possible.

b.

Minimize grading that would create cut and fill slopes visible from Highway 41 and 101.

c.

Minimize building height and mass by using low-profile design here applicable. Minimize building appearance by using colors to harmonize with the surrounding natural environment.

d.

Provide landscaping to screen and buffer development through extensive use of trees and large-growing shrubs in compliance with Chapter 22.16.

4.

Residential land divisions - Cluster development encouraged. Residential land divisions are encouraged to be clustered in compliance with Section 22.22.140, unless standard subdivision design can include clustered residential building sites that will be in equal conformity with standards B.2.c through B.2.i. Application review shall determine whether the proposed parcels are designed so that residential buildings, accessory buildings and roads will be in conformity with standards H.3.a through H.3.d, in addition to other applicable standards.

Guideline: Retain land in open space in new land divisions that will preserve existing views of land subject to the Highway corridor design standards.

a.

Open Space parcel incentive. Cluster divisions of land that are subject to the Highway Corridor Design Standards may utilize an open space parcel area that is smaller than required by Chapter 22.22. The size of the area may be determined by a visual analysis of the area subject to the Highway Corridor Design Standards as part of the subdivision review process. The analysis shall identify the area that is necessary to maintain open space views of features identified in the Highway Corridor Design Standards.

C.

San Luis Obispo Highway Corridor Area. All projects within the Sensitive Resource Area in the San Luis Obispo sub-area of the San Luis Obispo Planning Area and South County Planning Area and all residential structures, residential access roads, residential accessory structures, and certain agricultural structures on any land within the highway corridor design area shown in Figure 10-22 are subject to the standards in this subsection, in addition to all other applicable standards of this Title. The highway corridor design area supplements the Sensitive Resource Area combining designation that is applied to the most critical scenic resources such as the Morros. The Highway Corridor Design Standards are intended to protect views of scenic backdrops and background vistas and foreground views from scenic roads and highways, and other environmental resources that provide habitat and watershed drainage.

==> picture [360 x 476] intentionally omitted <==

Figure 10-22: Areas subject to Highway Corridor Design Standards

Purpose and applicability. The primary purpose of the following standards is to protect important views, natural landmarks, scenic backdrops, important plant and animal habitats, and watershed values. Chapter 6 of the San Luis Obispo Area Plan includes further discussion of the public interests served by the SRA designations and standards, including general descriptions of the geographic areas to which the SRA has been applied. These standards are intended to promote the protection of existing scenic resources and expedite the permit process through a ministerial Zoning Clearance for proposals meeting the specific design criteria, while also enabling alternative design solutions through a discretionary (Minor Use Permit or Conditional Use Permit) land use permit. Residential structures, residential accessory structures (including water tanks), residential access roads, specified agricultural accessory structures (including water tanks) and signs are governed by these standards. All other uses and structures are not subject to these standards, such as production agriculture, agricultural roads and nursery specialties.

2.

Permit requirement. For projects where the applicant chooses to comply with the requirements of Subsection C.3, Zoning Clearance is required for (1) residential structures, (2) residential accessory buildings, (3) residential access roads, and (4) agricultural accessory structures that are larger than 600 square feet in area and have one or more of the following: (a) a roof pitch of less than 3:12, (b) wall surfaces that are not wood, wood-appearing or textured, and/or (c) service entrances, such as bay doors, facing a highway, unless one of the following conditions apply:

a.

Biological impacts. If conformance with these standards would unavoidably impact a biological habitat, the Director, in consultation with the Environmental Coordinator, may waive the applicable standard.

b.

Project not visible. An exemption from this standard may be granted if documentation is provided demonstrating that the proposed structures and access roads will not be visible from the applicable scenic highway or railroad. Such documentation shall at minimum provide topographic, construction and building elevations with preliminary grading and building plans. A visual analysis of the project's location may also be useful to facilitate a decision.

c.

Project not consistent with Zoning Clearance requirements. If the Zoning Clearance application cannot be approved as consistent with the provisions of Subsection C.3, the application may be converted to a Minor Use Permit application subject to the provisions of Subsection C.4, with the applicant paying the difference in fees, for a discretionary review of the project.

d.

Other land use permit required. Projects for which Section 22.06.030 requires Minor Use Permit or Conditional Use Permit approval shall be subject to those land use permit requirements, and evaluated for compliance with Subsection C.4 (Discretionary Permit Requirements).

Zoning Clearance requirements.

a.

Site visit required. The Zoning Clearance application shall be subject to two site visits; one during the time of application review to confirm that conditions on the site correspond to information provided in the application, and the other prior to final building inspection or release of bond to confirm that the building and site improvements agree with the approved plan. (The planting of required landscaping improvements may be delayed up to 90 days after final building inspection when installation is guaranteed by bond.)

b.

Permit threshold. Where possible, residential buildings, residential accessory structures and agricultural accessory structures shall be set back 100 feet as shown in Figure 108-3 from the applicable scenic highway or railroad right-of-way that is designated in Chapter 6 of the San Luis Obispo Area Plan. If there is no feasible development area outside this setback, the project shall be located on the rear half of the property and shall provide a landscaping screen of moderately fast-growing, drought-tolerant plant material to provide 80 percent view coverage at plant maturity. A landscaping plan in compliance with Chapter 22.16 (Landscaping Standards) shall be provided at the time of Building Permit application submittal.

==> picture [384 x 246] intentionally omitted <==

Figure 10-23: Setback Threshold for Zoning Clearances

c.

Biological habitats. Development shall be designed and located to minimize adverse impacts to important biological resources in conforming with these standards. If there is a conflict between biological resources and these standards, protecting the biological resources takes precedence.

d.

Ridgetop development. Structures within the SRA shall not be located so as to be silhouetted against the sky as viewed from any of the scenic highway or railroad corridors designated in Chapter 6 of the San Luis Obispo Area Plan, illustrated in Figure 10-24.

h.

Landscaping. A landscaping plan is required adjacent to the applicable structure to obtain at least 50 percent view screening of the structure at plant maturity, as illustrated in Figure 10-28. Landscaping shall include mitigation planting or seeding for graded cut and fill slopes and a low water-use irrigation system.

==> picture [276 x 225] intentionally omitted <==

Figure 10-28: Landscaping

4.

Discretionary permit requirements. Minor Use Permit approval is required for projects that are unable to meet the requirements for a Zoning Clearance as specified in Subsection C.3. Any Minor Use Permit and Conditional Use Permit applications that may otherwise be required by this Title shall include a visual analysis prepared by a registered architect, registered landscape architect, or other qualified person acceptable to the Director. The visual analysis shall be utilized to determine compliance with the intent of the provisions of Subsection F.3, and the following.

a.

Locations of development. Locate all development including accessory structures (including water tanks) and access roads in the least visible portion of the site as viewed from any of the scenic highway or railroad corridors designated in Chapter 6 of the San Luis Obispo Area Plan, consistent with the protection of other resources. Use existing topographic features first and vegetation second to screen development from public view as much as possible.

b.

Grading. Minimize grading that would create cut and fill slopes visible from any of the scenic highway or railroad corridors designated in Chapter 6 of the San Luis Obispo Area Plan.

c.

Slope limitation. Grading for structures and roads shall occur on slopes that are less than 30 percent.

d.

Building visibility. Minimize building height and mass by using low-profile design where applicable. Minimize building visibility (including water tanks) by using colors to harmonize with the surrounding natural

environment.

e.

Landscaping. Provide landscaping to screen and buffer development with native or drought-resistant plants, including extensive use of evergreen trees and large-growing shrubs, in compliance with Chapter 22.16. Shapes of plant materials should be similar to native vegetation.

f.

Signs. Locate signs that are required to have a land use permit, especially freestanding signs, so that they do not interfere with vistas from any of the scenic highway or railroad corridors designated in Chapter 6 of the San Luis Obispo Area Plan.

5.

Residential land divisions - Cluster requirement. Residential land divisions shall be clustered in compliance with Section 22.22.140, unless modified clusters as allowed by this area plan, or standard subdivision practices such as clustered residential building sites will be of equal conformance with the provisions of Subsection C.3. Application review shall determine whether the proposed parcels or building sites are designed so that residential buildings, accessory buildings and roads will comply with Subsection F.4, in addition to other applicable standards.

6.

Open space preservation. This standard applies to sites located within the Sensitive Resource Area but not the Highway Corridor Design Standards. In compliance with the purpose of the Sensitive Resource Area to retain visual appearance, habitats, drainage ways and watershed values, open space preservation is a compatible measure to support the approval of new development. Approval of an application for any land division, Minor Use Permit or Conditional Use Permit (excluding any agricultural accessory building) is contingent upon the applicant executing an agreement with the County to maintain portions of the site in open space use that are within the SRA and not intended for development. The required open space area shall be in rough proportionality to the visual impacts of the project. Guarantee of open space preservation may be in the form of public purchase, agreements, easements controls or other appropriate instrument, provided that such guarantee agreements are not to grant public access unless acceptable the property owner.

7.

Hillside parcels at the southeast City limits. The following standards apply to the area shown in Figure 1029 in addition to the above standards for Sensitive Resource Areas.

a.

Permit requirement. Minor Use Permit approval is required for all new structures except agricultural and residential accessory structures and accessory dwelling units.

b.

Sites visible from local streets. Views of the site from Broad Street shall replace those from other scenic highways or the railroad in determining compliance with the above standards for Sensitive Resource Areas.

==> picture [384 x 290] intentionally omitted <==

Figure 10-29: Hillside parcels on the southeast side of San Luis Obispo

D.

South County Highway Corridor Area. Highway 101 corridor design standards in the South County area are as follows:

1.

Purpose. The purpose of the following Highway 101 corridor design standards is to provide public views of:

·

varied topography including ridgelines and rock features;

·

significant stands of trees and wildflowers; and

·

historic buildings and pastoral settings.

These standards are intended to expedite the permit process for projects which maintain scenic views and the rural character along Highway 101, while providing opportunities to use other design solutions through

a discretionary review process to achieve scenic goals. Only residential structures, residential accessory building, residential access roads, specified agricultural accessory buildings and signs are governed by these standards. All other uses and structures, such as agricultural roads and nursery specialties are not subject to the standards.

2.

Applicability. The following standards apply to the Highway 101 corridor shown in Figures 10-30 and 10-31, and the Newsom Ridge hills shown in Figure 10-30. These standards also apply to the Temattate Ridge hills, east of Highway 101 between Los Berros Creek and Highway 166. Along the Temattate Ridge, south of Los Berros Creek, these standards apply to land above the 800-foot elevation and not beyond 40 feet in vertical elevation below the highest elevation on the back of the ridge at any given point along the ridgeline.

3.

Permit requirements. Zoning Clearance is required for residential structures, residential accessory buildings and residential access roads that comply with the provisions of Subsection D.4. Projects that do not choose to comply with the provisions of Subsection D.4 shall require Minor Use Permit approval, or a Conditional Use Permit if otherwise required by Section 22.06.030.

Within the Highway 101 frontage (limited to the first 300 feet) shown in Figures 10-30 and 10-31, Zoning Clearance is also required for agricultural accessory buildings larger than 600 square feet, individually or cumulatively, that have a roof pitch of less than 3:12, unarticulated wall surfaces and/or service entrances facing the highway.

If the Zoning Clearance application cannot be approved in compliance with Subsection D.4, the application may be converted to a Minor Use Permit application for review of the project, with the applicant paying the difference in application fees.

4.

Project design and processing - Zoning Clearance applications. Projects proposed in Zoning Clearance applications on sites within or partially within the highway corridors shown in Figures 10-30 and 10-31 shall comply with the following, in addition to other applicable standards:

a.

Exemption. An exemption from this standard may be granted if documentation is provided that the project will not be visible from Highway 101. Such documentation shall at a minimum provide topographic, construction and building elevations with preliminary grading and building plans. Submission of a visual analysis of the project's location may be useful to facilitate a decision. If conformance with these standards would unavoidably impact a biological habitat, the Director, in consultation with the Environmental Coordinator, may waive the applicable standard.

b.

Site visit required. Zoning Clearance applications shall be subject to two site visits; one during the time of application review to confirm that conditions on the site correspond to information provided in the application, and the other prior to final building inspection to confirm that the building and site improvements agree with the approved plan. (Planting of required landscaping improvements may be delayed up to 90 days after final building inspection when installation is guaranteed by bond.)

c.

Highway setback. Where possible, residential buildings, residential accessory structures and agricultural accessory structures described in Subsection D.3 shall be set back 100 feet from the Highway 101 right of way as shown in Figure 10-32. If there is no feasible development area outside this setback, the project shall be located on the rear half of the property and shall provide a landscaping screen to provide 80 percent coverage at plant maturity, to be verified by a landscape architect, landscape contractor, certified nurseryman or other qualified individual approved by the Director.

==> picture [360 x 245] intentionally omitted <==

==> picture [384 x 230] intentionally omitted <==

Figure 10-33: Ridgetop Development

e.

Slope limitation. Grading for structures and roads shall occur on slopes that are 20 percent or less, except on the west side of Highway 101 where more restrictive standards may apply as shown in Figure 10-34.

Zoning Clearance is required for development on slopes of 20 percent or less, and Minor Use Permits on slopes greater than 20 percent.

==> picture [384 x 160] intentionally omitted <==

Figure 10-34: Slope Limitation

f.

Building features. Maximum building height is 25 feet above natural grade, as illustrated in Figure 10-35. This height limit may be increased an additional five feet for agricultural accessory buildings subject to an adjustment as provided in Section 22.70.030 subject to a visual study that supports a finding that buildings will have appropriate forms to minimize their visual impact on surrounding properties and Highway 101. The additional height shall be for architectural features such as cupolas or gabled vents on no more than onethird the length of any building. Building architecture shall include roofs with a minimum pitch of 3:12 and articulated wall surfaces at least every 30 feet. Where possible, agricultural accessory buildings within 300 feet of Highway 101 shall have service entrances oriented away from view of Highway 101. Building color shall be similar to surrounding natural colors that are no brighter than 6 in chroma and value on the Munsell color scale on file in the Department.

==> picture [384 x 159] intentionally omitted <==

Figure 10-35: Building Features

g.

Landscaping. A landscaping plan is required that will ensure at least 50 percent screening of the structure at plant maturity as shown in Figure 10-36. Landscaping shall include mitigation planting or seeding for graded cut and fill areas in compliance with Chapter 22.16.

==> picture [348 x 288] intentionally omitted <==

Figure 10-36: Landscaping

h.

Biological habitats. Development shall be designed and located to minimize adverse impacts to important biological resources in conforming with these standards. If there is a conflict between biological resources and these standards, protecting the biological resources takes precedence.

5.

Project design and processing - Discretionary permit applications. Minor Use Permit approval is required for projects subject to Subsection D.4 that are unable to meet the requirements for a Zoning Clearance in standards D.4.c through D.4.h. Minor Use Permit and any Conditional Use Permit applications that may otherwise be required by this Title shall include a visual analysis that is prepared by a registered architect, landscape architect or other qualified individual acceptable to the Environmental Coordinator. The visual analysis shall be utilized to determine compliance with the intent of D.4 and the following:

a.

Locate development, including access roads, in the least visible portion of the site consistent with the protection of other resources, as viewed from Highway 101, unless mitigated to insignificant levels. Use existing vegetation and topographic features to screen development from view as much as possible.

b.

Minimize grading for both structures and roads that would create cut and fill slopes visible from Highway 101.

c.

Minimize building height and mass by using low-profile design where applicable. Minimize the visual impacts of buildings by using colors that blend with surrounding natural colors and/or screen the building from view.

d.

Provide landscaping to screen and buffer both road and building development with native or droughtresistant plants, including the extensive use of trees and large-growing shrubs.

e.

Use of minimal signage is encouraged. Locate signs that are subject to a discretionary land use permit so that they minimize interference with important public views from Highway 101, such as those listed in the preamble to this Section.

6.

Residential land divisions.

a.

Clustering encouraged. Residential land divisions are encouraged to be clustered in compliance with Section 22.22.140, unless standard subdivision design can include clustered residential building sites that will be in equal conformity with Subsection I.5. Application review shall determine whether the proposed parcels or building sites are designed so that residential buildings, accessory buildings and roads will comply with Subsection I.5, in addition to other applicable standards.

Guideline: Retain land in open space in new land divisions that will preserve existing views of land subject to the Highway 101 corridor design standards.

b.

Open space parcel incentive. Cluster divisions of land that are located within the Highway 101 corridor design standards may utilize an open space parcel area that is smaller than required by Section 22.22.140. The size of the area may be determined by a visual analysis of the area subject to the Highway 101 corridor standards as part of the subdivision review process. The analysis shall identify the area that is necessary to maintain open space views of features identified in the Highway 101 corridor design standards.

22.10.100 - Lot Consolidation.

In any residential or Rural Lands land use category, any single ownership of two or more adjoining vacant lots with continuous frontage, shall be considered a single parcel of real property except as otherwise provided by this Section. No sale or transfer, or division of less than all of such single parcel shall occur unless the portion or portions of the single parcel to be sold, transferred or divided, are in conformity with the provisions of this Title as modified by this Section.

Notes:

(1)

Minimum width is measured along the front setback line (Section 22.10.140).

[Amended 1981, Ord. 2063] [22.04.050]

A.

Purpose and applicability. Minimum site area is the smallest existing lot size for which a building permit will be issued. Sections 22.10.100 through 22.10.110 set minimum site area standards for the use of existing lots of record. These standards are not to be used to determine the required parcel size for new land divisions, which are instead subject to Chapter 22.22 (Land Division Standards). Any legally created lot may be used for any use identified as allowable in the applicable land use category by Section 22.06.030 (Allowable Land Uses and Permit Requirements), regardless of whether the lot satisfies the minimum size requirements of Chapter 22.22 for new lots, provided that:

1.

The existing lot proposed for use is not smaller than the minimum site area required for the proposed use by Subsection C. (Required Area), or Chapter 22.30 (Standards for Specific Land Uses), or by the planning area standards of Article 9.

2.

The lot is of sufficient size to satisfy all applicable requirements of this Chapter, without the need for a variance based upon inadequate parcel size.

3.

The proposed use is authorized by the appropriate land use permit as determined by Article 2 or Chapter 22.30, or planning area standard of Article 9.

[Added 1984, Ord. 2163; Amended 1992, Ord. 2553]

B.

Area measured. For the purpose of determining whether a specific lot or contiguous lots satisfy these standards for minimum building site, no portion of an existing or proposed abutting street right-of-way shall be included in the area calculated.

C.

Required area. The following land uses shall be located only on sites with the minimum areas specified, unless other minimum site area requirements are established by Chapter 22.30 for specific uses, by Chapter 22.14 for combining designations or by planning area standards in Article 9.

Notes:

(1)

Except where a larger site area is provided by Section 22.10.100, Lot Consolidation, one acre is required where a well and septic system shall be located on a single lot; 2-½ acres is required where a lot is proposed to have a septic system, and is located within a Domestic Reservoir Watershed as defined by Section 19.20.222b(3) of the Building and Construction Ordinance, except that no minimum is required where a lot is part of an approved cluster subdivision with a maximum density of 2.5 acres per dwelling unit or more. No land within a horizontal distance of 200 feet from the reservoir impoundment, as determined by the spillway elevation, shall qualify for computing minimum site area, residential density, or for septic system siting; and

[Amended 1984, Ord. 2163; 1992, Ord. 2553] [22.04.040, 042, 044]

This Section establishes standards for acceptable exterior and interior noise levels and describe how noise shall be measured. These standards are intended to protect persons from excessive noise levels, which are detrimental to the public, health, welfare and safety and contrary to the public interest because they can: interfere with sleep, communication, relaxation and full enjoyment of one's property; contribute to hearing impairment and a wide range of adverse physiological stress conditions; and adversely affect the value of real property.

A.

9.

Traffic on public roadways, railroad line operations, aircraft in flight, and any other activity to the extent regulation thereof has been preempted by state or federal law.

B.

Exterior noise level standards. The exterior noise level standards of this Section are applicable when a land use affected by noise is one of the following noise-sensitive uses: residential uses listed in Section 22.06.030 (Allowable Land Uses and Permit Requirements), except for residential accessory uses and temporary dwellings; health care services (hospitals and similar establishments only); hotels and motels; bed and breakfast facilities; schools (pre-school to secondary, college and university, specialized education and training); churches; libraries and museums; public assembly and entertainment; offices, and outdoor sports and recreation.

1.

No person shall create any noise or allow the creation of any noise at any location within the unincorporated areas of the county on property owned, leased, occupied or otherwise controlled by the person which causes the exterior noise level when measured at any of the preceding noise-sensitive land uses situated in either the incorporated or unincorporated areas to exceed the noise level standards in the following table. When the receiving noise-sensitive land use is outdoor sports and recreation, the following noise level standards shall be increased by 10 dB.

Maximum Allowed Exterior Noise Level Standards

;sz=8q;Notes:

(1)

Applies only to uses that operate or are occupied during nighttime hours.

2.

In the event the measured ambient noise level exceeds the applicable exterior noise level standard in Subsection B.1, the applicable standard shall be adjusted so as to equal the ambient noise level plus one dB.

3.

Each of the exterior noise level standards specified in Subsection B.1 shall be reduced by five dB for simple tone noises, noises consisting primarily of speech or music, or for recurring impulsive noises.

4.

If the intruding noise source is continuous and cannot reasonably be discontinued or stopped for a time period whereby the ambient noise level can be measured, the noise level measured while the source is in operation shall be compared directly to the exterior noise level standards.

C.

Interior noise level standards. The interior noise level standards of this Section are applicable when the land use which is the source of noise and the land use which is affected by noise are both residential uses as listed in Section 22.06.030 (Allowable Land Uses and Permit Requirements), except for residential accessory uses and temporary dwellings.

1.

No person shall operate or cause to be operated a source of noise within a residential use in any location in the unincorporated areas of the county or allow the creation of any noise which causes the noise level when measured inside a residential use located in either the incorporated or unincorporated area to exceed the interior noise level standards in the following table.

2.

In the event the measured ambient noise level exceeds the applicable interior noise level standard in Subsection C.1, the applicable standard shall be adjusted so as to equal the ambient noise level plus one dB.

3.

Each of the interior noise level standards specified in Subsection C.1 shall be reduced by five dB for simple tone noises, noises consisting primarily of speech or music, or for recurring impulsive noises.

4.

If the intruding noise source is continuous and cannot reasonably be discontinued or stopped for a time period whereby the ambient noise level can be measured, the noise level measured while the source is in operation shall be compared directly to the interior noise level standards.

D.

Other noise sources. The noise level standards in this Section apply to the following.

1.

Air conditioning and refrigeration. Notwithstanding the provisions of Subsection B.1, when the intruding noise source is an air conditioning or refrigeration system or associated equipment installed prior to June 4, 1992, the exterior noise level as measured as provided in Subsection E. shall not exceed 55 dB, except where the equipment is exempt from the provisions of this Chapter. The exterior noise level shall not exceed 50 dB for equipment installed or in use after June 4, 1993.

2.

Waste and garbage collection equipment.

Sloping lot adjustment. In any case where the elevation of the natural grade on a lot at a point 50 feet from the centerline of the adjacent street right-of-way is seven feet above or below the elevation of the

centerline, required parking (including a private garage) may be located, at the discretion of the applicant, as close as five feet to the street property line, in compliance with Section 22.70.030 (Adjustment), provided that portions of the dwelling other than the garage shall be established at the setback otherwise required.

c.

Variable setback block. Where a residential block is partially developed with single-family dwellings having less than the required front setbacks, and no uniform front setback is established by a planning area standard, the front setback may be adjusted (Section 22.70.030) at the option of the applicant, as follows:

(1)

Prerequisites for adjustment. Adjustment may be granted only when 25 percent of the lots on the block with the same frontage are developed, and the entire block is within a single land use category.

(2)

Allowed adjustment. The normally required minimum front setback shall be reduced to the average of the front setbacks of the existing dwellings (which include attached garages but not detached garages), to a minimum of 10 feet.

d.

Planned development or cluster division. Where a new residential land division is proposed as a planned development, condominium or cluster division (Sections 22.22.140 and 22.22.145), front setbacks may be determined through Conditional Use Permit approval, provided that in no case shall setbacks be allowed that are less than the minimum required by the California Building Standards Code or Section 22.22.145, whichever is greater.

e.

a.

Selecting the setback location. Where double frontage setback locations are not specified by subdivision requirements or other applicable regulations, the applicant may, except as otherwise provided in this Section, select the front setback street unless 50 percent of the lots on a double frontage block are developed with the same front yard orientation. In that case all remaining lots shall orient their front setbacks with the majority.

b.

Double frontage setback requirements. A full front setback shall be provided adjacent to one frontage, and a setback of one-half the required front setback depth adjacent to the other frontage; except that where the site of a proposed multiple-residence project includes an entire block, the project shall be designed to provide required front setbacks on the two longest street frontages.

7.

Flag lots and easement access. The front setback for a lot with no street frontage other than a fee ownership access strip or an access easement extending from a public street to the buildable area of the lot shall be measured from the point where the access strip or easement meets the bulk of the lot, to establish a building line parallel to the lot line nearest to the public street.

A.

Purpose. The requirements in this Section are intended to reduce pollutant discharges to the Maximum Extent Practicable and to prevent stormwater discharges from causing or contributing to a violation of receiving water quality standards, also known as post-construction stormwater management. These requirements also emphasize protecting and, where degraded, restoring key watershed processes to create and sustain linkages between hydrology, channel geomorphology, and biological health necessary for healthy watersheds. Maintenance and restoration of watershed processes impacted by stormwater management is necessary to protect water quality and the beneficial uses of surface and groundwater.
