Editor's note— For purposes other than Coastal Development Permits, additional Development Code (Title 22) sections may apply. All standards listed below are applicable in the Coastal Zone. In addition, this Title specifies permitting requirements that may be applicable for particular land uses, including Design Review, Sign Permits, and Accessory Dwelling Unit Permits. In all cases, these permit requirements apply independent of and in addition to the Coastal Development Permit requirements identified in Chapter 20.68 (Coastal Development Permit Requirements) for development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), proposed to be undertaken within the Coastal Zone.

Chapter 20.01 - PURPOSE AND APPLICABILITY OF COASTAL ZONE REGULATIONS

Sections:

Title 20 identifies permit requirements and development standards for proposed development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), in the unincorporated areas of Marin County within the Coastal Zone established by the California Coastal Act of 1976. This Title implements applicable provisions of the Coastal Act and the Marin County Local Coastal Program and Land Use Plan, which, among other things identify the location and density of development, provide for visitor-serving facilities, provide for public access to and along the coast, and protect significant public views and natural resources. Chapters 20.60 through 20.70 inclusive, along with portions of Chapters 20.32 (Standards for Specific Land Uses) and 20.130 (Coastal Zoning Code Definitions) that apply in the coastal zone together constitute the LCP's Implementation Plan (Coastal Zoning Code).

(Ord. No. 3791, § III(Exh. A), 2023)

The requirements of this Title apply to all proposed development, as defined in Chapter 20.130 (Coastal Zoning Code), within the Coastal Zone. These requirements apply in addition to all other applicable provisions of this Development Code. In the event of any perceived conflict between the requirements of

the LCP's Implementation Plan and any other provisions of Title 22 (Development Code), the Implementation Plan shall control.

(Ord. No. 3791, § III(Exh. A), 2023)

All development in the Coastal Zone within the County's Coastal Development Permitting jurisdiction shall be consistent with the Marin County LCP and, where located between the nearest public road and the sea or the shoreline of any body of water located within the coastal zone, be supported by a specific finding that the development is in conformity with the public access and public recreation policies of Chapter 3 of the Coastal Act.

An application for a farmhouse or intergenerational home shall identify all legal lots owned by the same owner of the property upon which the proposed farmhouse or intergenerational home is located including all contiguous legal lots under common ownership (the "farm tract"). The application shall identify all existing agricultural dwellings on the identified legal lots and shall demonstrate that the proposed farmhouse or intergenerational house is located on a legal lot.

D.

Nothing in this subsection shall be construed to prohibit the sale of any legal lot comprising the farm tract, nor require the imposition of any restrictive covenant on any legal lot comprising the farm tract other than the legal lot upon which development of one farmhouse and up to two intergenerational homes is approved. Future development of other legal lots comprising the farm tract shall be subject to the provisions of the LCP and Title 20 (Coastal Zoning Code), including, but not limited to, Section 20.65.040 (C-APZ Zoning District Standards).

E.

No allowable farmhouse or intergenerational home may be divided from the rest of the legal lot. As a condition of permit approval for a farmhouse and/or intergenerational home, future land division of the legal lot containing the farmhouse and/or intergenerational home(s) is prohibited except that lease of the rest of the legal lot at a level of agricultural use that will sustain the agricultural capacity of the site is not prohibited.

Where denial would be inconsistent with FTA and the reviewing authority finds there is no feasible alternative, approval of the facilities is also subject to all of the following written findings: (1) There is no alternative facility configuration that would avoid impacts inconsistent with all other applicable standards of the certified LCP; (2) Impacts are avoided to the maximum extent feasible; (3) Unavoidable impacts are minimized and mitigated to the maximum extent feasible; and (4) The facility can be found consistent with all otherwise applicable LCP standards.

1.

New telecommunication facilities shall not be permitted where co-location on existing facilities would provide equivalent coverage with less impact to coastal resources.

2.

The placement of co-located facilities on an existing wireless telecommunication facility shall require a Coastal Development Permit except that if a Coastal Development Permit was issued for the original wireless telecommunication facility and that Coastal Development Permit authorized the proposed new colocation facility, the terms and conditions of the underlying Coastal Development Permit shall remain in effect and no additional Coastal Development Permit shall be required.

3.

New telecommunications facilities shall not be permitted in Ridge and Upland Greenbelt areas, unless no other technically feasible and available site exists; provided, wireless communications facilities should be permitted in ridge and upland greenbelt areas where they are co-located with existing structures and are consistent with the policies and programs of the LCP. Applications for new telecommunications facilities in Ridge and Upland Greenbelt areas shall include technical information prepared by qualified professionals that sufficiently demonstrates that no other technically feasible site is available to provide adequate coverage consistent with Federal law requirements. For the purposes of this section, any determination that no other technically feasible site is available shall be made in writing and supported by evidence.

4.

New or expanded sites shall ensure co-location and other efficient use of facilities to minimize the need for new sites, particularly on ridgeline and/or visually sensitive locations. Site users and operators shall be encouraged to share and/or consolidate facilities to the greatest extent possible. Facilities that may be shared include buildings, access roads, parking areas, utilities, transmitters, towers and other structures, and antennas.

5.

All telecommunication facilities shall be sited and designed to avoid, and where unavoidable, to minimize, visual impacts to the maximum extent feasible, including by visually blending with the predominant landscape, co-locating with existing facilities, landscaping consisting of non-invasive/native plants, coloring and materials to blend with the existing landscape, and shall be the minimum height necessary to provide adequate service coverage consistent with Federal law requirements. A visual analysis of the facility shall be submitted with the application materials to assess the proposed facility at design capacity. The visual analysis shall include a photo-montage or photo-simulation, and/or poles erected at the proposed site. The analysis shall address views of the proposed facility from public vantage points, including views from public roads, trails, lookouts, parks, and beaches. The analysis shall also depict cumulative conditions by including information on existing, approved, and proposed telecommunications facilities that will or may eventually be approved at the proposed site.

6.

Telecommunications support facilities such as vaults and equipment rooms, utilities and other support structures shall be placed underground, depressed, earth bermed, or sited below ridgelines or other significant public line of sight to the greatest extent feasible. All facilities shall visually blend with the surrounding built and natural environments.

7.

New telecommunications facilities shall protect significant public views as required by Policy C-DES-2 (Protection of Visual Resources).

8.

New telecommunications facilities proposed on parcels restricted by agricultural, open space, scenic or other public easement or restriction will only be permitted in accordance with the terms of such public easement or restriction.

9.

Applications for new or expanded telecommunications facilities shall contain long range plans which project market demand and long-range facility expansion needs.

10.

Development of telecommunications facilities shall be consistent with LCP policies requiring the protection of coastal resources, including Environmentally Sensitive Habitat Areas and prime agricultural land. Such facilities shall be evaluated for the potential for significant adverse effects on plant and animal species, including the potential to interfere with the migratory flyway or flight path used by resident bird species, and where clearing native vegetation is required for facility construction or expansion. Where potential significant effects are identified, appropriate mitigation including siting, design, and monitoring shall be required to avoid, and/or offset if unavoidable, such effects.

11.

All coastal development permit approvals granted for telecommunications facilities shall include a condition that the permit be authorized and renewed via a new Coastal Development Permit at least every 10 years. When reviewing requests for permit renewal, the Applicant shall incorporate all feasible new or advanced technologies that will reduce previously unavoidable impacts to the maximum extent feasible or the permit will not be renewed.

In the event two or more parcels are consolidated through the approval of a lot line adjustment, merger, parcel or Tentative Map, or reversion to acreage in compliance with Title 22, Article VI (Subdivisions), where a single parcel is covered by two or more zoning districts, the consolidated parcel should be reviewed by the Director to determine whether the parcel should be rezoned to a single zoning district.

C.

Measurements, calculations. Explanations of how height limits, site coverage requirements, and floor area ratios (FAR) apply to sites and projects are in Chapter 20.64 (Coastal Zone Development and Resource Management Standards).

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Purpose of Section. This Section provides regulations for development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), proposed within the coastal agricultural and resource-related zoning districts established by Section 20.62.030 (Coastal Zoning Districts Established). The purpose of these zoning districts is to protect agricultural land, continued agricultural uses and the agricultural economy by maintaining parcels large enough to sustain agricultural production, preventing conversion to nonagricultural uses, and prohibiting uses that are incompatible with long-term agricultural production or the

rural character of the County's Coastal Zone and to preserve important soils, agricultural water sources, and forage to allow continued agricultural production on agricultural lands. (Policy C-AG-1, Agricultural Lands and Resources)

B.

Purposes of zoning districts. The purposes of the individual zoning districts are as follows.

1.

C-APZ (Coastal, Agricultural Production Zone) District. The C-APZ zoning district is intended to preserve agricultural lands that are suitable for land-intensive or land-extensive agricultural production. (Policy C- AG-2, Coastal Agricultural Production Zone)

The principal permitted use of lands in the C-APZ district is agriculture, limited to the types of agricultural development set forth below and in Land Use Plan Policy C-AG-2, and only allowed when consistent with the development standards set forth in Section 20.65.040 (C-APZ Zoning District Standards):

a.

Agricultural production: use of land for the breeding, raising, pasturing, and grazing of livestock; the production of food and fiber; the breeding and raising of bees, fish, poultry, and other fowl; the planting, raising, harvesting and producing of agriculture, aquaculture, mariculture, horticulture, viticulture, vermiculture, forestry crops, and plant nurseries;

b.

Agricultural accessory structures and agricultural accessory activities;

c.

Agricultural dwelling units, consisting of

(1)

One farmhouse or a combination of one farmhouse and one intergenerational home per farm tract, consistent with C-AG-5, including combined total size limits, and;

(2)

Agricultural worker housing, providing accommodations consisting of not more than 36 beds in group living quarters per legal parcel or 12 units or spaces per legal lot for agricultural workers and their households;

d.

Other Agricultural Uses, limited to the following uses that are appurtenant and necessary to the operation of agriculture

(1)

Agricultural product sales and processing of products grown within the farmshed, provided that for sales, the building(s) or structure(s) or outdoor areas used for sales do not exceed an aggregate floor area of 500 square feet, and for processing, the building(s) or structure(s) used for processing activities do not exceed an aggregate floor area of 5,000 square feet:

(2)

Not for profit educational tours.

Conditional uses in the C-APZ zone, as specified in Table 5-1 of Chapter 20.62 (Coastal Zoning Districts and Allowable Land Uses), include a second intergenerational home per farm tract, for-profit educational tours, agricultural homestay facilities, agricultural worker housing above 12 units or 36 beds per legal lot and additional agricultural uses and non-agricultural uses including land division, consistent with Section 20.65.040 (C-APZ Zoning District Standards). Development shall not exceed a maximum density of 1 unit per 60 acres. Densities specified in the zoning are maximums and not entitlements and may not be achieved when the standards of the Agriculture policies and, as applicable, other LCP policies are applied. (Policy C-AG-1, Agricultural Lands and Resources and Coastal and Policy C-AG-2, Coastal Agricultural Production Zone).

The C-APZ zoning district is consistent with the Agriculture 1 land use category of the Marin County Land Use Plan.

2.

C-ARP (Coastal, Agricultural, Residential Planned) District. The C-ARP district applies to lands adjacent to residential areas in the Coastal Zone that have potential for agricultural production but promote the concentration of residential development to maintain the maximum amount of land available for agricultural use. The C-ARP district provides flexibility in lot size and building locations to concentrate development to maintain the maximum amount of land for agricultural use, and to maintain the visual, natural resource and wildlife habitat values of subject properties and surrounding areas. The C-ARP district requires the clustering of proposed development. The C-ARP zoning district is consistent with the Agriculture 1, 2, and 3 land use categories of the Marin County Land Use Plan. Residential use shall be the principal permitted use in all parcels with the land use designation of C-AG3; Agriculture shall be the principal permitted use in all parcels with the C-AG1 and C-AG2 land use designations. (Policy C-AG-3, Coastal Agricultural Planned Zone C-ARP)

3.

C-OA (Coastal, Open Area) District. The C-OA District provides for open space, outdoor recreation, and other open lands, including areas particularly suited for park and recreational purposes, access to beaches, natural drainage channels, and areas that serve as links between major recreation and open space reservations. The C-OA zoning district is consistent with the Public and Quasi Public - Open Space land use category of the Marin County Land Use Plan.

C.

Allowed land uses and permit requirements in agricultural/resource districts. Table 5-1 lists the land uses allowed in the agricultural/resource zoning districts within the Coastal Zone, in compliance with Chapter

D.

Development standards for agricultural- and resource-related districts. Proposed development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), shall comply with all provisions of the LCP, including Chapters 20.32 (Standards for Specific Land Uses), this Chapter, Chapter 20.64 (Coastal Zone Development and Resource Management Standards), 20.65 (Coastal Zone Planned District Development Standards), 20.66 (Coastal Zone Community Standards), and 20.68 (Coastal Development Permit Requirements).

20.62.090 - Coastal Special Purpose and Combining Districts.

A.

Purpose of Section. This Section provides regulations for development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), in the coastal special purpose and combining zoning districts established by Section 20.62.030 (Coastal Zoning Districts Established).

B.

Purpose and applicability of zoning districts.

1.

General Applicability.

a.

Special purpose districts. Special purpose zoning districts are intended to identify sites suitable for types of land uses that are different from but that can be accommodated along with certain land uses allowed within the other coastal agricultural, residential, and commercial zoning districts established by Section 20.62.030 (Coastal Zoning Districts Established).

b.

Combining districts. Combining districts are applied to property together with one of the other agricultural, residential, or commercial zoning districts, to highlight areas where important site, neighborhood, or area characteristics require particular attention in project planning.

(1)

The combining districts established by this Chapter provide standards that apply to development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), in addition to those of zoning districts.

(2)

The applicability of a combining district to property is shown by its map symbol established by Section 20.62.030 (Coastal Zoning Districts Established) being shown as a suffix to the symbol for the primary zoning district. A site designated within a combining district shall be subject to all applicable provisions of this Chapter, in addition to the requirements of the primary zoning district. If provisions of this Chapter conflict with any requirements of a primary zoning district, this Chapter shall control.

2.

C-PF (Coastal, Public Facilities) Zoning/Combining District.

a.

The Coastal Public Facilities "C-PF" zoning/combining district is applied to land in the Coastal Zone suitable for public facilities and public institutional uses, including where a governmental, educational, or other institutional facility is the primary use of the site, in compliance with the Marin County Local Coastal Program. The C-PF district is consistent with the Public Facility and Quasi-Public Facility land use categories of the Marin County Land Use Plan.

b.

The C-PF district may be applied to property as a primary zoning district if it is sufficiently different from surrounding land uses as to warrant a separate C-PF zoning district, and as a combining district where a publicly-owned site accommodates land uses that are similar in scale, character, and activities, to surrounding land uses.

3.

B (Coastal, Minimum Lot Size) Combining District. See Section 20.64.040 (Coastal Minimum Lot Size (-B) Combining District) for the purpose and applicability of this district.

C.

Development standards for special purpose/combining districts. Proposed development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), shall comply with the provisions of Chapter 20.32 (Standards for Specific Land Uses) as applicable and all other applicable provisions of this Title.

(Ord. No. 3791, § III(Exh. A), 2023)

Chapter 20.64 - COASTAL ZONE DEVELOPMENT AND RESOURCE MANAGEMENT STANDARDS

This chapter provides general standards for proposed development, including site planning, and appropriate land use, for the following coastal zoning districts: C-APZ (Coastal, Agricultural Production Zone), C-ARP (Coastal, Agricultural, Residential Planned), C-OA (Coastal, Open Area), C-RA (Coastal, Residential, Agricultural), C-R1 (Coastal, Residential, Single-Family), CRSP (Coastal, Residential, SingleFamily Planned), C-RSPS (Coastal, Residential, Single-Family Planned, Seadrift Subdivision), C-R2 (Coastal, Residential, Two-Family), C-RMP (Coastal, Residential, Multiple Planned), C-VCR (Coastal, Village Commercial/Residential), C-H1 (Coastal, Limited Roadside Business), C-CP (Coastal, Planned

Commercial), C-RMPC (Coastal, Residential/Commercial Multiple Planned) zoning districts, and the -B (Minimum Lot Size) combining district.

(Ord. No. 3791, § III(Exh. A), 2023)

The provisions of this Chapter apply to proposed development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), in all coastal zoning districts, which requires Coastal Development Permit approval in addition to the requirements of Chapters 20.62 (Coastal Zoning Districts and Allowable Land Uses), 20.65 (Coastal Zone Planned District Development Standards), 20.66 (Coastal Zone Community Standards), and all other applicable provisions of this Development Code. In addition to specific standards applicable to a particular land use, all other LCP requirements also apply.

(Ord. No. 3791, § III(Exh. A), 2023)

Proposed development within the coastal zoning districts established by Section 20.62.030 (Coastal Zoning Districts Established) shall be sited, designed, constructed in compliance with the minimum lot area, density, setback requirements, height, and floor area ratio requirements shown in Table 5-4 (Coastal Zone Development Standards), as well as all other applicable LCP requirements.

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Purpose. The Coastal Minimum Lot Size "-B" combining district is intended to establish lot size, area, and setback requirements for division of land that are different from those normally applied by the primary zoning district applicable to a site; and to configure development on existing lots, where desirable, because of specific characteristics of the area.

B.

Development standards. Where the -B combining district is applied, the minimum lot area, average lot width, and depths of front, side, and rear yards in Table 5-5 (Coastal -B Combining District Development Standards) shall be required, instead of those that are normally required by the primary zoning district. The maximum residential density for proposed division of land for that portion or portions of properties with Environmentally Sensitive Habitat Areas and buffers, hazardous areas and setbacks, and properties that lack public water or sewer systems, shall be calculated at the lowest end of the density range as established by the governing Land Use Category, except for projects that provide significant public benefits, as determined by the Review Authority, or lots proposed for affordable housing, and where it can be demonstrated that the development will avoid and protect all Environmentally Sensitive Habitat Areas and Environmentally Sensitive Hazard Area buffers, will avoid all hazardous areas and hazard setbacks, and will be served by on-site water and sewage disposal systems.

20.64.050 - Biological Resources.

A.

Submittal requirements.

1.

Biological studies.

a.

Initial Site Assessment Screening. The Marin County Community Development Agency (CDA) shall conduct an initial site assessment screening of all development proposals to determine the potential presence of an Environmentally Sensitive Habitat Area (ESHA). The initial site assessment screening shall include a review of reports, resource maps, aerial photographs, site inspection and additional resources as necessary to determine the presence of ESHA.

b.

Site Assessment. A site assessment shall be submitted for those Coastal Development Permit applications where the initial site assessment screening reveals the potential presence of an ESHA within 100 feet of any portion of the proposed development. The permit will be subject to a level of review that is commensurate with the nature and scope of the development. A site assessment shall be prepared by a qualified biologist and shall confirm the extent of the ESHA, document any site constraints and the presence of other sensitive resources, recommend setbacks, and development timing, including required buffers, and provide other information, analysis and potential modifications necessary to protect the resource. If the site assessment identifies impacts, then the report shall analyze alternatives to avoid impacts to ESHA; shall, if ESHA impacts cannot be avoided, include findings identifying why there are no feasible alternatives to avoid ESHA impacts, and shall identify appropriate mitigation measures. Where habitat restoration or creation is required to eliminate or offset potential impacts to an ESHA, a detailed Restoration and Monitoring Plan shall be required, as provided in this section.

c.

Buffer Areas. Buffers shall be provided for ESHAs in accordance with the policies of C-BIO-3 (ESHA Buffers), C-BIO-18 (Wetland Buffers), or C-BIO-23 (Coastal Streams and Riparian Vegetation), in combination with the findings of a site assessment, as necessary to ensure the biological integrity and preservation of the habitat they are designed to protect. Maintain ESHA buffers in their natural condition, except as provided in C-BIO-19 (Wetland Buffer Adjustments), C-BIO-25 (Stream Buffer Adjustments) or C- BIO-4 (Protect Major Vegetation).

Determination of ESHA buffer requirements shall consider the following:

1)

Habitat requirements of the ESHA, including the migratory patterns of affected species and tendency to return each season to the same nest site or breeding colony;

2)

Sensitivity of the ESHA to disturbance;

3)

Topography of the site;

4)

Movement of stormwater;

5)

Permeability of the soils and depth to water table;

6)

Vegetation present;

7)

Unique site conditions;

8)

Whether vegetative, natural topographic, or built features (e.g., roads, structures) provide a physical barrier between the proposed development and the ESHA; and

9)

The likelihood of increased human activity and disturbance resulting from the project relative to existing development.

10)

A buffer reduction shall be considered only when supported by evidence that the reduction is unavoidable, is the minimum necessary, will prevent impacts that degrade the ESHA, and will be compatible with the continuance of ESHA.

d.

Habitat Mitigation. New development shall be sited and designed to avoid impacts to ESHA. If proposed development is a permissible use in ESHA, but there is no feasible alternative, including the no project alternative, that can avoid significant impacts to ESHA, then the alternative that would result in the fewest or least significant impacts shall be selected. Residual adverse impacts to ESHA shall be fully mitigated, with priority given to on-site habitat mitigation. Off-site or fee-in-lieu habitat mitigation measures shall only be approved when it is not feasible to fully mitigate impacts on-site or where off-site habitat mitigation is more protective in the context of a biological analysis prepared by a qualified scientist and approved by the County of Marin. Any determination that it is infeasible to mitigate impacts onsite shall be supported by written findings. Mitigation shall not substitute for implementation of the project alternative that would avoid impacts to ESHA.

Allowable habitat mitigation shall occur in accordance with the provisions of C-BIO-20 (Wetland Impact Mitigation) for wetlands and the findings of a site assessment and shall be provided at a minimum ratio of 2:1 for on-site mitigation; 3:1 for off-site mitigation or 4:1 for an in-lieu fee where applicable. In determining required mitigation, the acreage of habitat impacted shall be determined based on the size of the approved development area, road/driveway area, and required fuel modification on the project site, as well as required vegetation clearance and other disturbance, if any, on adjacent properties. Habitat mitigation may be required at an adjusted ratio or through other appropriate techniques as commensurate with the extent

of habitat disruption, based on the specific requirements of the ESHA as determined through the site assessment.

2.

Site map. Coastal Permit applications shall contain a detailed site plan showing existing and proposed construction, with major vegetation, water courses, natural features, and other probable wildlife areas.

20.64.060 - Environmental Hazards.

A.

Dune Protection.

1.

No development, including grading, erection of fences, signs or other primary of accessory structures shall be permitted seaward of that undeveloped right-of-way known as Mira Vista Street in Stinson Beach.

2.

Except for those shoreline protective works otherwise permitted by this chapter, development, including signs, fences, and grading activities shall not be permitted seaward of the established building setback lines established by zoning districts for shoreline parcels.

3.

Development of shorefront lots within the Stinson Beach and Seadrift area shall assure preservation of the existing sand dune formations in order to protect environmentally sensitive dune habitat, vegetation and to maintain the natural protection from wave runup which such natural dunes provide. Where no dunes are evident, new development shall, to the maximum extent feasible, be set back behind the first line of

terrestrial vegetation. Development approvals for new projects located along such shorefront parcels shall be accompanied by findings, including mitigation conditions, establishing the project's design and location, minimizing the need for shoreline protective works, protective works, protecting sandy beach habitat, providing a buffer area between public and private use areas, protecting the scenic and recreational character of the beach and maintaining the public rights of access to and use of beach dry sand areas. Permits authorizing repair and maintenance to existing shoreline structures shall to the extent feasible, provide for the above standards and objectives.

4.

Project proposals for the subdivision of beach front lots shall be permitted only upon explicit findings that the increased development density and/or location is consistent with the standards and objectives established in subdivision 3 of this subsection.

5.

No development shall be permitted in the sensitive coastal dune habitats in order to preserve dune formations, vegetation and wildlife habitats. Overuse in dune areas shall be prevented by such mechanisms as restricting parking, directing pedestrian traffic to areas capable of sustaining increased use, and fencing. No motor vehicles shall be permitted in beach or dune areas except for emergency purposes.

B.

Shoreline Protection.

1.

Bluff Top Setbacks. New structures shall be set back from coastal bluff areas a sufficient distance to ensure with reasonable certainty that they are not threatened from cliff retreat within their economic life expectancies. Adequate setback distances will be determined for information contained in required geologic reports and the setback formula established below. These setbacks will be of sufficient distance to eliminate the need for shoreline protective works. The following formula will be used to determine setbacks from the bluff for new structures:

Setback (meters) = structure of life (yeasts, normally at least 40 years) X retreat rate (meters/year). In areas where vigorous sliding is taking place, and additional 15 meters should be added as a safety factor.

The retreat rate shall be determined by a geotechnical investigation conducted by a professional engineer or registered geologist which explicitly examines the site's geotechnical capability to adequately support the proposed development. The report shall include the historic and projected rate(s) of bluff retreat attributable to wave and/or surface runoff erosion. The geotechnical report shall be required in either of the following:

a.

The building or proposed development site is within one hundred fifty feet of a blufftop.

b.

The building site is located within stability zones 3 or 4 as indicated on the slope stability maps for the Bolinas and Tomales areas, which maps accompany Wagner's 1977 report, "Geology for Planning, Western Marin County." This report and accompanying maps are incorporated by reference as part of this chapter.

2.

Standards and requirements for shoreline protective works. Revetments, breakwaters, groins, harbor channels, seawalls, cliff retaining walls, and other such construction that alters natural shoreline process shall be permitted only when:

a.

Required to serve coastal-dependent uses or to protect existing structures (constructed before adoption of the LCP).

b.

No other nonstructural alternative is practical or preferred.

c.

The condition causing the problem is site specific and not attributable to a general erosion trend, or the project reduces the need for a number of individual projects and solves a regional erosion problem.

d.

The structure will not be located in wetlands or other significant resource or habitat area, and will not cause significant adverse impacts to fish or wildlife.

e.

There will be no reduction in public access, use and enjoyment of the natural shoreline environment, and construction of a structure will preserve or provide access to relates public recreational lands or facilities.

f.

The structure will not restrict navigation, mariculture or other coastal use and will not create a hazard in the area in which it is built.

In the absence of an overall wave hazard/shoreline erosion study, any permit application for seawalls, riprap or other protective structures on beaches, shall be accompanied by engineering reports stating the nature and extent of wave erosion hazard along the beach area and an explanation of how the proposed protective works will mitigate the hazard, both on and off the project site. This requirement shall not apply to emergency permit applications applied for prior to January 1, 1983. Emergency permit applications after that date shall be subject to report requirement or shall specifically establish why the need for such protective devices was not foreseen and previously addressed through nonemergency permit applications.

Applications for placement of protective structures on beaches shall be accompanied by an engineer's report unless an overall wave hazard/shoreline erosion report exists. The engineers report shall include:

a.

A statement of the nature and extent of wave erosion hazard;

b.

An analysis of how the proposed protective works will mitigate the hazard both on and off the site;

The planning commission, following consultation with the director of public works, may modify the said requirement in subdivision 1 above for selected areas or types of projects where the commission finds that:

i.

The project area is of the same general geologic nature and sufficient data has been developed (such as by a "Master Engineering Report") to adequately judge the risk and resulting standards necessary for such areas; or

ii.

The type of project is a minor structure, not for human habitation, which presents little risk on or off site, by possible geologic hazards.

2.

If unavoidable impacts are identified, require commensurate and proportional public access mitigation, such as requiring new or enhanced public trails or facilities, and potentially in lieu fees. Impacts on public access include, but are not limited to, intensification of land use resulting in overuse of existing public accessways, creation of physical

obstructions or perceived deterrence to public access, and creation of conflicts between private land uses and public access.

2.

Public coastal access in new developments. New public access from the nearest public roadway to the shoreline and along the coast shall be provided per Land Use Plan Policy C-PA-2 (Provide New Public Coastal Access in New Development). Where a requirement to dedicate public access is related in nature and extent to the impacts of the proposed development, the dedication of a lateral, vertical and/or bluff top accessway shall be required per Land Use Plan Policy C-PA-9 Variety of Public Coastal Accessways), unless Land Use Plan Policy C-PA-3 (Exemptions to Providing New Public Coastal Access) provides an exemption. A finding that an accessway can be located ten feet or more from an existing single-family residence or be separated by a landscape buffer or fencing if necessary shall be considered to provide adequately for the privacy of existing homes. All Coastal Development Permits subject to conditions of approval pertaining to public access and open space or conservation easements shall be subject to the procedures specified in Section 13574 of the Coastal Commission's Administrative Regulations.

3.

Direct dedication of public coastal access. If feasible, direct dedication of an easement or fee title interest for a required coastal accessway is preferred per Land Use Plan Policy C-PA-4 (Direct Dedication of Public Coastal Access, if Feasible).

4.

Acquisition of new public coastal accessways. The acquisition of additional public coastal accessways shall be pursued through available means per Land Use Plan Policy C-PA-6 (Acquisition and Location of New Public Coastal Accessways through Suitable Means).

5.

Protection of prescriptive rights. New development shall be evaluated to ensure that it does not interfere with the public's right of access to the sea where acquired through historic use per Land Use Plan Policy C-PA-7 (Protection of Prescriptive Rights).

6.

Bolinas Mesa. Public use of the two access trails across Bolinas Mesa to the RCA beach and of the RCA beach area itself shall be protected per Land Use Plan Policy C-PA-8 (Bolinas Mesa).

7.

Impacts of public coastal accessways on their surroundings. Coastal accessways and their support facilities shall be sited and designed to avoid impacts to environmental resources, agriculture, and surrounding neighbors per Land Use Plan Policy C-PA-10 (Impacts of Public Coastal Accessways on their Surroundings) and C-PA-11 (Privacy of Neighbors).

8.

Public coastal accessway maintenance and liability agreements. Maintenance and liability responsibilities for coastal accessways shall conform to Land Use Plan Policy C-PA-12 (Agreements for Maintenance and Liability Before Opening Public Coastal Accessways).

9.

Accessibility of public coastal accessways. New public coastal accessways shall comply with California Title 24 and be accessible to persons with disabilities to the maximum extent feasible (Land Use Plan Policy C-PA-13).

10.

Impacts of new development on public coastal accessways. New development shall be sited and designed to avoid impacts to users of coastal access and recreation areas per Land Use Plan Policy C-PA-15 (Impacts of New Development on Public Use of Coastal Accessways).

11.

Parking, signage, and support facilities at public coastal accessways. Where appropriate and feasible, parking, signage, and support facilities shall be provided in conjunction with public coastal accessways per Land Use Policy C-PA-18 (Parking and Support Facilities at Public Coastal Accessways) and C-PA-19 (Explanatory Signs at Public Coastal Accessways). Proposals to restrict public parking near beach access points or parklands shall be evaluated per Land Use Plan Policy C-PA-20 (Effects of Parking Restrictions on Public Coastal Access Opportunities).

12.

Shoreline protection structures near public coastal accessways. The construction of shoreline protection structures shall maintain or enhance existing shoreline access per Land Use Plan Policy C-PA-21 (Shoreline Structures on or Near Public Coastal Accessways).

Chapter 20.65 - COASTAL ZONE PLANNED DISTRICT DEVELOPMENT STANDARDS

20.65.010 - Purpose of Chapter.

A.

This Chapter provides detailed site planning, development, and land use standards for the planned zoning districts within the Coastal Zone. These districts include C-APZ, C-ARP, CRSP, C-RSPS, C-RMP, C-CP, C- RMPC, and C-RCR.

B.

These standards are intended to ensure that proposed development is designed and constructed in a manner compatible with, and sensitive to, the important environmental characteristics and visual features of lands designated within coastal planned zoning districts.

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Compliance with standards required. Proposed development, as defined in Chapter 20.130 (Coastal Zoning Code Definitions), shall be designed and constructed in conformity with:

1.

All standards and requirements established through the approval of a Coastal Development Permit;

2.

Any provisions of this Chapter applicable to a specific planned coastal zoning district;

3.

The provisions of Chapter 20.64 (Coastal Zone Development and Resource Management Standards); and

4.

All provisions of Sections 20.62.060 (Coastal Agricultural and Resource Related Districts), 20.62.070 (Coastal Residential Districts), or 20.62.080 (Coastal Commercial and Mixed-Use Districts);

5.

All applicable provisions of the Implementation Plan, as defined in Chapter 20.01 (Purpose and Applicability of Coastal Zone Regulations) and Chapter 20.130 (Coastal Zoning Code Definition).

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Access:

1.

Roads. Road designs shall minimize road length and maximize the amount of undivided agricultural land, except that longer road extensions may be necessary in highly visible areas in order to avoid or minimize other impacts. Roads shall be designed with not more than 18 feet pavement width, except when safety requirements require otherwise. If otherwise LCP consistent, a minimum of 16 feet may be permitted in certain very low use areas, as provided in the improvement standards established in compliance with Sections 24.04.020 et seq. of the County Code (Roads).

2.

Driveways. Driveways shall be designed in compliance with Sections 24.04.240 et seq. of the County Code (Driveways), in addition to and independent of Coastal Development Permit requirements. Driveway length shall be minimized, consistent with the clustering requirements of Subsection D.1 below (Building Location - Clustering Requirement). Applicants are encouraged, to the extent permitted by applicable laws, to utilize pervious surface materials (e.g., turfblock, pavers, porous asphalt and gravel) for new or modified driveways to reduce the area of impervious surface and the extent of storm water runoff.

B.

Fire protection. In areas without water systems, on-site water storage capacity may be required for each single-family dwelling, subject to the requirements of the County Fire Department or local Fire Protection District, as applicable. Where feasible, the design of planned or cluster developments should include provisions for common water storage facilities and distribution systems. Maintenance of these water storage facilities and distribution systems should be performed according to a plan prepared by the applicant and approved by the County Fire Department or local Fire Protection District, as applicable.

C.

Building design:

1.

Height limits for structures:

(a)

The height limit is 25 feet for primary structures and 15 feet for accessory structures. (See also height limit provisions for the Seadrift Subdivision in Section 20.65.070.D (Seadrift Subdivision Height Limit) and the shoreline of Tomales Bay in Sections 20.66.080.C and 20.66.090.B (Tomales Bay Shoreline Development Standards)).

(b)

The floor level of the first floor shall not exceed 10 feet above natural grade at the lowest corner.

(c)

Structures located within the ridgeline areas pursuant to Subsection D.2 below shall be limited to a maximum height of 18 feet.

2.

Materials and colors. Building materials and colors should incorporate earth tones and be chosen to blend into the natural and built environment unobtrusively, to the greatest extent possible. Traditional colors for agricultural structures (natural wood, red, whitewash, etc.) are appropriate for these structures in agricultural zoning districts.

D.

Building location:

1.

Clustering requirement. Structures shall be clustered in a geologically stable, accessible location on the site where their visual prominence is minimized, consistent with the maximum protection of agricultural lands and other coastal resources. Clustering is especially important on open grassy hillsides; however, a greater scattering of buildings on wooded hillsides may be approved, if consistent with all other applicable provisions of the LCP. Construction shall be minimized by placing buildings so that they will be screened by existing vegetation, rock outcroppings or depressions in topography.

Proposed development shall be located close to existing roads and shall not require new road construction or improvements resulting in significant impacts on agriculture, significant vegetation, significant scenic resources, or natural topography of the site. Proposed development shall be sited to minimize impacts on scenic resources, wildlife habitat and streams, and adjacent agricultural operations.

2.

Development near ridgelines. No construction shall occur on top of, or within 300 feet horizontally, or within 100 feet vertically, of visually prominent ridgelines, whichever is more restrictive, unless no other suitable locations are available on the site or the lot is located substantially within the ridgeline area as defined

herein. If structures must be placed within this restricted area because of site constraints or because siting the development outside of the ridgeline area will result in greater visual or environmental impacts, they shall be in locations that are the least visible from public viewing areas.

3.

Energy conservation. Solar access shall be considered in the location, design, height and setbacks of all structures. Generally, structures should be oriented in a north/south fashion with the majority of glazing on the south wall or walls of the buildings.

4.

Noise mitigation. Noise impacts on residents in nearby areas shall be minimized through the placement of buildings, recreation areas, roads and landscaping.

E.

Division of Agricultural Lands. Permissible divisions of land affecting agricultural lands shall be designed consistent with the requirements of both Titles 20 and 22 and the Land Use Plan. In considering divisions of agricultural lands in the Coastal Zone, the County may approve fewer parcels than the maximum number of parcels allowed by both the Development Code and the Land Use Plan, based on site characteristics such as topography, soil, water availability, environmental constraints and the capacity to sustain viable agricultural operations, and coastal resource protection.

F.

Landscaping. Introduced landscaping shall be designed to minimally disturb natural areas and shall be compatible with the native plant setting. Landscaping plans shall be prepared with consideration for fire protection, water quality protection, solar access, the use of native and drought tolerant species, and

minimal water use. Planting should not block public views or scenic views from adjacent properties or disturb wildlife trails.

G.

Open space areas:

1.

Dedication required. Land to be preserved as open space may be dedicated by fee title to the County or an agency or organization designated by the County before issuance of any construction permit or may remain in private ownership with appropriate scenic and/or open space easements or other encumbrances acceptable to the County, and the County may require reasonable public access across lands remaining in private ownership, consistent with federal and state law.

2.

Maintenance. The County or other designated agency or organization shall maintain all open space lands accepted in fee title, as well as public access and trail easements across private property. Where open space lands remain in private ownership with scenic easements, these lands shall be maintained in compliance with the adopted policies of the Marin County Open Space District and may require the creation of a homeowners' association or other organization to maintain private open space lands where appropriate.

3.

Open space uses. Uses in open space areas shall be in compliance with policies of the Marin County Open Space District, in addition to complying with the LCP, and shall have no significant impact on the natural environment and coastal resources. Pedestrian and equestrian access shall be provided where possible and reasonable and LCP consistent.

H.

Site preparation:

1.

Grading. Grading is permitted in compliance with Section 20.64.080(C) (Grading and Excavation Standards) and shall be minimized. Every reasonable effort shall be made to retain the natural features of the land: skylines and ridgetops, rolling land forms, knolls, native vegetation, trees, rock outcroppings, and watercourses. Where grading is required, it shall not create flat planes and sharp angles of intersection with natural terrain. Slopes shall be rounded and contoured to blend with existing topography.

2.

Drainage. The areas adjacent to creeks shall be kept as much as possible in their natural state. All construction shall ensure drainage into the natural watershed in a manner that will avoid significant erosion or damage to creeks and adjacent properties. Impervious surfaces shall be minimized. At creek crossings,

bridges shall be utilized instead of culverts consistent with Section 20.64.050.B.11 (Coastal Streams, Riparian Vegetation, and Buffers).

3.

Trees and vegetation. Every effort shall be made to avoid tree removal, and changes or construction that would cause the death of existing trees, rare plant communities, and wildlife habitats.

4.

Fire hazards. Development shall be permitted in areas subject to wildfire threat only where it is consistent with the requirements of C-BIO-4 (Protect Major Vegetation) and C-DES-11 (Avoidance of Fuel Modification) and the review authority determines there are good access roads, and adequate water supply, and vegetation management plans are required and adopted.

5.

Geologic hazards. Construction shall not be permitted on identified seismic or geologic hazards, including slides, natural springs, identified fault zones, or on bay mud, without approval from the Department of Public Works, based on acceptable soils and geologic reports. Development subject to coastal hazards shall be sited and designed to avoid such hazards consistent with Chapter 20.64 (Environmental Hazards).

6.

Watershed areas. All projects within water district watershed areas shall be referred to the appropriate district for review and comment. Damaging impoundments of water shall be avoided.

I.

Utilities. In ridge land areas, street lights shall be of low-level intensity and low in profile. In all areas, power and telephone lines shall be underground where feasible. Any determination that undergrounding of utilities is not feasible shall be made in writing.

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Purpose. This Section provides additional development standards for the C-APZ zoning district designed to preserve productive lands for agricultural use, and ensure that development is accessory and incidental to, in support of, and compatible with agricultural production. "Appurtenant and necessary for agricultural production" means that the proposed development is needed to sustain an efficient and productive agricultural operation and to ensure continued agricultural viability.

B.

Applicability. The requirements of this Section apply to proposed development in addition to the standards established by Section 20.65.030 (Planned District General Development Standards) and Chapter 20.64

(Coastal Zone Development and Resource Management Standards), and all other applicable provisions of this Coastal Zoning Code.

C.

Development standards. Development permits in the C-APZ district shall be subject to the following standards and requirements in addition to Section 20.65.030 (Planned District General Development Standards):

1.

Standards for all development in the C-APZ:

a.

Permitted development shall protect and maintain renewed and continued agricultural production and agricultural viability on-site and shall not impact adjacent agricultural lands. Permitted development shall be sited to avoid land suitable for agricultural production (i.e., prime agricultural land or other land suitable for agriculture) whenever possible, consistent with the operational needs of agricultural production. If use of such land is necessary, prime agricultural land shall not be utilized if it is possible to utilize other lands suitable for agricultural use. In addition, as little agricultural land as possible shall be used for structural development.

b.

Development shall be permitted only where adequate water supply, sewage disposal, road access and capacity and other public services are available to support the proposed development after provision has been made for existing and continued agricultural production. Water diversions or use for a proposed development shall not adversely impact stream or wetland habitats, have significant effects on groundwater resources, or significantly reduce freshwater inflows to water bodies including Tomales Bay, either individually or cumulatively.

c.

Permitted development shall have no significant adverse impacts on environmental quality or natural habitats, and shall meet all other applicable policies, consistent with the LCP.

d.

In order to retain the maximum amount of land in agricultural production or available for future agricultural use, farmhouses, intergenerational homes, agricultural worker housing, agricultural accessory structures, and agricultural product processing facilities shall be placed within a clustered development area, except when:

(1)

Placement outside such areas is necessary for agricultural operations (e.g., when a more remote barn is required in a different part of the property to allow for efficient agricultural operations or a retail sales facility needs to be close to a public road); or

(2)

When placement inside such areas would be inconsistent with applicable LCP standards (e.g., when such placement would be within a required stream setback area). In this case, new development shall be placed as close as possible to the existing clustered development area in a way that also meets applicable LCP standards.

The clustered development area, in combination with roads, agricultural sales facilities, and other structure development shall total no more than five percent of the gross acreage, to the extent feasible with the remaining acreage retained in or available for agricultural production or open space.

Development shall be located close to existing roads and shall not require new road construction or improvements resulting in significant impacts on agriculture, natural topography, major vegetation, or significant natural visual qualities of the site. Development shall be sited to minimize impacts on coastal resources and adjacent agricultural operations and shall be designed and sited to avoid hazardous areas.

e.

Agricultural dwelling units shall meet the standards, specified in Section 20.32.024 (Agricultural Dwelling Units).

2.

Standards for Non-Principally Permitted Uses and Development. In addition to the standards of Section 1, above, all of the following development standards apply to non-principally permitted uses and development.

a.

Non-principally permitted uses and development shall only be allowed when such uses will serve to maintain and enhance agricultural production.

b.

The creation of a homeowners' or other organization and/or the submission of an Agricultural Production and Stewardship Plan (APSP) may be required to provide for the proper utilization of agricultural lands, including their availability on a lease basis or for the maintenance of the community's roads, septic or water systems.

3.

Standards for Non-Agricultural Conditional Uses and Development. In addition to the standards of Sections 1 and 2 above, all of the following development standards apply to non-agricultural conditional uses and development.

a.

Conservation easements. Consistent with state and federal laws, the approval of non-agricultural conditional development, including land divisions, shall include measures for the long-term preservation of

lands proposed or required to remain undeveloped. Preservation shall be accomplished by permanent conservation easements or other encumbrances acceptable to the County. Only agricultural uses shall be allowed under these encumbrances. In addition, the County shall require the execution of a covenant prohibiting further division of parcels created in compliance with this Section and Article VI (Subdivisions), so that each is retained as a single unit.

b.

Agricultural Production and Stewardship Plans. The creation of a homeowners' association or other organization and/or the submission of an Agricultural Production and Stewardship Plan (APSP) may be required to provide for the proper use and management of agricultural lands, including their availability for lease, and/or for the maintenance of community roads or mutual water systems. Submission of an APSP shall be required for approval of all land division and shall be required for all other non-agricultural development of C-APZ lands, except as provided for in (2) below.

(1)

The purpose of an Agricultural Production and Stewardship Plan prepared and submitted for land division or other non-agricultural development of C-APZ lands is to ensure that long-term agricultural productivity will occur and will substantially contribute to Marin's agricultural industry. Such a plan shall clearly identify and describe existing and planned agricultural uses for the property, explain in detail their implementation, identify on-site resources and agricultural infrastructure, identify product markets and processing facilities (if appropriate), and demonstrate how the planned agricultural uses substantially contribute to Marin's agricultural industry. An APSP shall provide evidence that at least 95% of the land will remain in agricultural production or natural resource protection and shall identify stewardship activities to be undertaken to protect agriculture and natural resources. An APSP shall be prepared by qualified professionals with appropriate expertise in agriculture, land stewardship, range management, and natural resource protection. The approval of a development proposal that includes an APSP shall include conditions ensuring the proper, long-term implementation of the plan.

(2)

The requirement for an Agricultural Production and Stewardship Plan shall not apply to the farmhouse, agricultural worker housing or to intergenerational homes. The APSP may also be waived for nonagricultural land uses when the County finds that the proposal will enhance current or future agricultural use of the property and will not convert the property to primarily residential or other non-agricultural use, as evidenced by such factors as bona fide commercial agricultural production on the property, the applicant's history and experience in production agriculture, and the fact that agricultural infrastructure (such as fencing, processing facilities, marketing mechanisms, agricultural worker housing, or agricultural land leasing opportunities) has been established or will be enhanced.

(3)

Projects subject to the potential requirement of preparing an Agricultural Production and Stewardship Plan shall be referred to such individuals or groups with agricultural expertise as appropriate for analysis and a recommendation. Such individuals or groups shall also be requested to periodically review and evaluate the effectiveness of the APSP program.

c.

Required findings. Review and approval of Coastal Development Permits for non-agricultural development, including land divisions and determinations of allowed density in the C-APZ zoning district, shall be subject to the following written findings, in addition to others required by this LCP.

1.

The proposed development is necessary because the agricultural use of the property is no longer feasible. Any determination that agricultural use of the property is no longer feasible shall be made in writing and be supported by evidence. The purpose of this standard is to permit agricultural landowners who face economic hardship to demonstrate how development on a portion of their land would ease the hardship and enhance agricultural operations on the remainder of the property.

2.

The proposed development will not conflict with the continuation or initiation of agricultural uses on the portion of the property that is not proposed for such development, on adjacent parcels, or on other agricultural parcels within one mile of the perimeter of the proposed development.

3.

Appropriate public agencies are able to provide necessary services (fire protection, police protection, schools, etc.) to serve the proposed development without extending urban services.

4.

No land division shall result in any parcel less than 60 acres. Land divisions are prohibited unless the agricultural productivity of any resulting lots and on adjacent parcels is not reduced. Land divisions shall only be allowed upon demonstration that the long-term agricultural productivity, including on each parcel to be created, would be maintained and enhanced and that agricultural productivity on adjacent parcels would be maintained.

6.

Land divisions shall only be permitted where 50% of the usable parcels in the area have been developed and the created parcels would be no smaller than the average size of surrounding parcels, except that lease of a legal parcel at a level of agricultural use that will sustain the agricultural capacity of the site is not prohibited.

7.

Land divisions shall be prohibited if the resulting lots cannot be developed consistent with the LCP.

d.

Transfer of development rights (TDR). Proposed development within the C-APZ district may use the TDR provisions of Chapter 22.34 (Transfer of Development Rights), so long as such a transfer is otherwise LCP consistent.

4.

Agricultural Dwelling Unit Impacts and Agricultural Use. Ensure that lands designated for agricultural use are not de facto converted to residential use, thereby losing the long-term productivity of such lands, by the following means:

1.

Agricultural dwelling units, other than principally permitted agricultural dwelling units, shall be reviewed to ensure they serve to maintain and enhance agricultural production and do not diminish current or future agricultural production on the property or convert it to primarily residential use.

2.

Any proposed agricultural dwelling unit and related development subject to a Coastal Development Permit shall comply with LCP policies including ensuring that the mass and scale of new or expanded structures respect environmental site constraints and the character of the surrounding area. Such development must be compatible with ridge protection policies and avoid tree-cutting and grading wherever possible. All such

development shall be clustered with existing structures and development on the farm, pursuant to Section 20.65.040.C.1.d (Standards for All Development in the C-APZ) and shall be sited and designed to protect significant public views.

When considering proposed agricultural dwelling units, other than principally permitted agricultural dwelling units, the reviewing authority shall exercise its discretion in light of some or all of the following criteria for the purpose of ensuring that the land does not de facto convert to residential use:

a.

The applicant's history of production agriculture.

b.

How long term agricultural use of the property will be preserved — for example, whether there is an existing or proposed dedication or sale of permanent agricultural easements or other similar protective agricultural restrictions such as Williamson Act contract or farmland security zone.

c.

Whether long term capital investments in agriculture and related infrastructure, such as fencing, processing facilities, market mechanisms, agricultural worker housing or agricultural leasing opportunities has been established or is proposed to be established.

d.

Whether sound land stewardship practices, such as organic certification, riparian habitat restoration, water recharge projects, fish-friendly farming practices, or erosion control measures, have been or will be implemented.

e.

Whether the proposed development will facilitate the ongoing viability of agriculture such as through the intergenerational transfer or lease of existing agricultural operations.

3.

In no event shall an agricultural dwelling subject to these provisions exceed 7,000 square feet in size. Where a farmhouse and one or two intergenerational dwellings are allowed in the C-APZ zone, the aggregate development of all such agricultural dwellings on the subject farm tract shall not exceed 7,000 square feet. However, agricultural worker housing, up to 540 square feet of garage space for each farmhouse, agricultural accessory structures, and up to 500 square feet of office space in the farmhouse used in connection with the agricultural operation on the property shall be excluded from the 7,000 square foot limitation.

4.

The square footage limitations noted in the above criteria represent maximum agricultural dwelling unit sizes and do not establish a mandatory entitlement or guaranteed right to development; rather, site constraints and resource protection standards may require reduced size limits in any particular case.

5.

Agricultural homestays, bed & breakfasts, home occupations, care facilities, group homes and similar permissible uses allowed in the C-APZ zone may only occur within otherwise allowable agricultural dwelling units and not within additional separate structures.

(Ord. No. 3791, § III(Exh. A), 2023)

20.65.050 - C-ARP Zoning District Standards.

A.

Purpose. This Section provides development standards for the C-ARP zoning district designed to preserve productive lands for agricultural use through the clustering of allowed development.

B.

Applicability. Proposed development shall comply with the provisions of Section 20.65.030 (Planned District General Development Standards), and Chapter 20.64 (Coastal Zone Development and Resource Management Standards).

C.

Allowable land uses. Residential use shall be the principal permitted use in all parcels with the land use designation of C-AG3. Agriculture shall be the principal permitted use in all parcels with the C-AG1 and C- AG2 land use designations.

D.

Land division requirements. Where otherwise consistent with the standards specified in Chapter 20.70.190 (Land Divisions), land divisions of small agricultural holdings within the C-ARP zoning district shall conform

to the following standards:

1.

Land division applications shall include information demonstrating to the Director that the design of proposed parcels provides the maximum feasible concentration of clustering.

2.

Clustered development shall be located both to provide for the retention of the maximum amount of land in agricultural use and to protect important wildlife habitat areas.

Development clusters shall also be located to maintain the visual resources and environmentally sensitive areas of the site and surrounding areas.

3.

Open space easements or other restrictions shall be required to designate intended use and restrictions on the property being subdivided.

E.

Agricultural and open space uses. Agricultural uses shall be encouraged in the C-ARP zoning district.

1.

As part of the Coastal Development Permit review process, usable agricultural land should be identified, and efforts made to preserve and/or promote its use to the maximum extent feasible. Agricultural land not presently in production shall be preserved to the maximum extent feasible as undeveloped private open space to be made available on a lease basis in the future for compatible agricultural uses. The primary intent shall be to preserve open lands for agricultural use, not to provide open space/recreational land uses that will interfere or be in conflict with agricultural operations.

2.

Lands to be preserved for agriculture and/or open space use may require the creation of a homeowners' association or other organization for their maintenance.

3.

The nature and intensity of large scale agricultural uses should be described in the form of an Agricultural Production and Stewardship Plan (APSP). The APSP should consider intensity of grazing, runoff protection, chemical and fertilizer use and, in order to preserve agricultural land practices, separation from existing or proposed residential uses.

4.

Pedestrian and/or equestrian access shall be provided across lands remaining in private ownership where consistent with adopted County and coastal plans, and where consistent with federal and state law.

(Ord. No. 3791, § III(Exh. A), 2023)

The provisions of this Chapter apply to the preparation, filing, review, and approval or denial of all applications for development in Marin County, whether such approval or denial occurs through a Coastal Development Permit, De Minimis Waiver, Exemption, or Categorical Exclusion.

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Application and filing. Coastal Development Permit application submittals shall include all information and other materials required by the Coastal Development Permit application forms, provided by the Agency, including any information identified as necessary for specific categories of development or for development proposed in specific geographic areas. The application and accompanying materials shall be filed with the Agency before or concurrent with an application for any land use permit required by Title 22. The Coastal Development Permit application shall include:

1.

Project plans and supporting materials sufficient to determine whether the project complies with all relevant policies of the Local Coastal Program;

2.

Documentation of the applicant's legal interest in all the property upon which work is proposed to be performed, and all contiguous properties under the same ownership. The area subject to the Coastal Development Permit may include such contiguous properties where the Director finds that necessary to achieve the requirements of the Local Coastal Program. The reviewing authority shall consider all contiguous properties under the same ownership when reviewing development in the C-APZ zoning district. The area covered by a proposed project may also include multiple ownerships.

3.

A dated signature by or on behalf of each of the applicants, attesting to the truth, completeness and accuracy of the contents of the application and, if the signer of the application is not the applicant, written evidence that the signer is authorized to act as the applicant's representative and to bind the applicant in all matters concerning the application: and

B.

Determination of processing category. The Director shall determine if the proposed development is categorically excluded, exempt, qualifies for a De Minimis Waiver, is or is not appealable to the Coastal Commission and/or requires a Coastal Development Permit that does or does not require a public hearing as set forth below. Notice of processing category determination shall be sent in compliance with the requirements specified for the particular permit category. All such determinations regarding permit category may be challenged in compliance with Section 20.70.040 (Challenges to Processing Category Determination).

1.

Categorical exclusion. A determination that development is categorically excluded shall comply with Section 20.68.040 (Coastal Development Permit Not Required: Categorically Excluded Development).

2.

Exemption. A determination that development is exempt from the requirement to obtain a Coastal Development Permit shall comply with Section 20.68.050 (Coastal Development Permit Not Required: Exempt Development) and with Section 20.68.060 (Coastal Development Permit Required: Non-Exempt Development).

3.

De Minimis Waiver. A determination that a project qualifies for a De Minimis Waiver shall comply with Section 20.68.070 (De Minimis Waiver of Coastal Development Permit).

4.

Non-public hearing applications. A public hearing shall not be required when an application is not appealable to the Coastal Commission by Section 20.70.080 (Appeal of Coastal Development Permit Decision), unless a public hearing is required for another discretionary planning permit for the same project or as determined by the Director.

5.

Public hearing applications. A public hearing shall be required when a project is defined as appealable to the Coastal Commission by Section 20.70.080 (Appeal of Coastal Development Permit Decision), unless the proposed project only entails the approval of an Accessory Dwelling Unit in a residential zone or if it qualifies for a public hearing waiver.

6.

Public hearing waiver for minor development. A public hearing that would otherwise be required for the below identified minor development shall be waived if both the following occur:

(a)

Notice is provided as required by Section 20.70.050 (Public Notice) that a public hearing shall be held upon request by any person, and

(b)

No request for a public hearing is received within 15 working days from the date of sending the notice required by Section 20.70.050 (Public Notice).

In addition to the requirements of Section 20.70.050 (Public Notice), the notice shall include a statement that the hearing will be cancelled if no person submits a request for a public hearing as provided above, and a statement that failure by a person to request a public hearing may result in the loss of that person's ability to appeal to the Coastal Commission any action taken by the County of Marin on the Coastal Development Permit application.

For purposes of this Section, "minor development" means a development that the Director determines satisfies all of the following requirements:

(1)

As proposed, is consistent with the certified Local Coastal Program,

(2)

Requires no discretionary approvals other than a Coastal Development Permit, and

(3)

As proposed, has no adverse effect either individually or cumulatively on coastal resources or public access to the shoreline or along the coast.

Notwithstanding the waiver of a public hearing, any written comments submitted regarding a Coastal Development Permit application shall be made part of the permit application record.

C.

Initial processing. A Coastal Development Permit shall be processed concurrently with other permit applications required for the project, and shall be evaluated as provided by Chapter 22.40 (Application Filing and Processing, Fees).

(Ord. No. 3791, § III(Exh. A), 2023)

Where an applicant or interested person disputes the Director's processing category determination, see Section 20.70.030.B (Determination of Processing Category), the determination may be challenged as follows:

A.

Challenges to Processing Category Determination. The Director's determination that a proposed development is to be processed as a categorical exclusion, exemption, de minimis waiver, non-public hearing application, or public hearing application may be challenged to the Coastal Commission within 10 working days after the date of the Commission receiving the public notice is required by this Chapter. The Director's determination that a proposed development is to be processed as a public hearing waiver for minor development may be challenged to the Coastal Commission within 15 working days after the date of the Commission receiving the public notice as required by this Chapter.

B.

Coastal Commission Challenge Procedures. Where an applicant, interested person, the County, or the Coastal Commission's Executive Director has a question as to any processing category determination under Section 20.70.030 (Coastal Development Permit Filing, Initial Processing) for a proposed development, the following procedures shall provide an administrative resolution process for determining the appropriate permit category:

(1)

The County shall make its determination as to the processing category for the proposed development in accordance with the procedure set forth in Section 20.70.030 (Coastal Development Permit Filing, Initial Processing).

(2)

County processing of the permit application shall cease if a challenge is received by the County and/or the Coastal Commission.

(3)

The Executive Director shall provide his or her opinion to the County, the applicant and any other known interested parties within 10 working days of the County's request unless the applicant and the County agree to an extension.

(a)

If the Executive Director agrees with the County's determination, then the determination shall be final and shall apply to the proposed development;

(b)

If the Executive Director disagrees with the County's determination, and the County then agrees with the Executive Director's opinion, then the review and permit procedures associated with the Executive Director's opinion shall apply to the proposed development; or

(c)

If the Executive Director disagrees with the County's determination, and the County disagrees with the Executive Director's opinion, then the matter shall be set for public hearing for the Coastal Commission to make the final determination of applicable review and permit procedures, and the Coastal Commission's determination shall apply to the proposed development.

(4)

The challenge period shall be deemed concluded if no challenge is received within the time periods specified in Section 20.70.040.B, or when the Executive Director provides his or her opinion to the County in outcomes (a) or (b) above, or when the Executive Director provides the Coastal Commission's determination to the County in outcome (c) above.

An application for an emergency shoreline protective device shall be accompanied by an engineering report. If the applicant is unable to provide all such information due to the nature of the emergency, then the applicant shall provide at a minimum: (a) a description of what measures, if any, were taken in advance in order to mitigate the hazard and (b) an analysis of alternatives, including the "no action" alternative.

6.

All required technical reports and project plans.

The Director shall verify the facts, including the existence and nature of the emergency, as time allows.

C.

Notice. The Director shall provide public notice of the proposed emergency work and determine the extent and type of notice based on the nature of the emergency. The Director shall notify the Executive Director of the Coastal Commission as soon as possible about potential emergency Coastal Development Permits, and shall report, in writing, to the Executive Director after the emergency Coastal Development Permit has been issued, the nature of the emergency, and the work involved.

D.

Emergency permit approval. The Director may grant an emergency permit upon reasonable terms and conditions, including an expiration date and the necessity for a Coastal Development Permit application later, if the Director finds that:

1.

An emergency (defined as a sudden unexpected occurrence demanding immediate action to prevent or mitigate loss or damage to life, health, property or essential services) exists that requires action more quickly than permitted by the procedures of this Title for a Coastal Development Permit, and the work can and will be completed within 30 days unless otherwise specified by the emergency permit;

2.

Public comment on the proposed emergency action has been reviewed, if time allows; and

3.

The proposed work is consistent with applicable Marin County Local Coastal Program policies.

The proposed work is the minimum amount of temporary development necessary to abate the emergency in the least environmentally damaging short- and long-term manner.

The decision to issue an Emergency Coastal Development Permit is at the sole discretion of the Director, provided that subsequent Coastal Development Permits required for the project shall comply with all applicable provisions of this Coastal Zoning Code.

E.

Coastal Development Permit required. All emergency Coastal Development Permits shall expire ninety (90) days after issuance, unless extended for good cause by the Planning Director, such extension is limited as much as possible in duration, and such extension is subject to challenge provisions per Section 20.70.040 (Challenges to Processing Category Determination). All emergency development pursuant to this section is considered temporary and must be removed and the affected area restored if it is not recognized by a regular Coastal Development Permit within 6 (six) months of the date of permit issuance, unless the Director authorizes an extension of time for good cause. Within 30 days of issuance of the Emergency Coastal Development Permit, the applicant shall apply for a regular Coastal Development Permit. Failure to file the applications and obtain the required permits shall result in enforcement action in compliance with Chapter 20.70.175 (Violations of Coastal Zone Regulations and Enforcement of LCP Provisions and Penalties).

20.70.150 - Coastal Zone Variances.

A.

This Section provides procedures for the adjustment from the development standards of this Coastal Zoning Code only when, because of special circumstances applicable to the property, including location, shape, size, surroundings, or topography, the strict application of this Title denies the property owner privileges enjoyed by other property owners in the vicinity and under identical zoning districts. Any Variance granted shall be subject to conditions that will ensure that the Variance does not constitute a granting of special privilege(s) inconsistent with the limitations upon other properties in the vicinity and zoning district in which the property is situated.

Title denies the property owner privileges enjoyed by other property owners in the vicinity and under identical zoning districts. Any Variance granted shall be subject to conditions that will ensure that the Variance does not constitute a granting of special privilege(s) inconsistent with the limitations upon other properties in the vicinity and zoning district in which the property is situated.

Variances provide relief from standards relating to height, floor area ratio, and yard setbacks. Variances shall not be granted for relief from use limitations or minimum lot size and density requirements, or any other LCP requirements.

1.

Filing. An application for a Variance shall be submitted, filed, and processed in compliance with and in the manner described in Chapter 20.70.030 (Coastal Development Permit Filing, Initial Processing). It is the responsibility of the applicant to establish evidence in support of the findings required by Section 20.70.070 (Required Findings).

2.

Project review procedure. Each application shall be analyzed by the Agency to ensure that the application is consistent with the purpose and intent of this Section.

3.

Action on Variances. Decisions on Variances shall be issued by the Director or the same review authority that issues the decision on the Coastal Development Permit for the project.

4.

Notice of action and/or hearing date. Administrative decisions and public hearings on a proposed Variance application shall be noticed in compliance with Section 20.70.050 (Public Notice).

B.

Decision and Findings on Variance. Following notice for an administrative Variance, or a public hearing for a Public Hearing Variance, the Review Authority shall issue a notice of decision in writing with the findings upon which the decision is based, in compliance with state law (Government Code Section 65906). The Review Authority may approve an application, with or without conditions, only if all of the following findings are made:

1.

There are special circumstances unique to the property (e.g., location, shape, size, surroundings, or topography), so that the strict application of this Coastal Zoning Code denies the property owner privileges enjoyed by other property owners in the vicinity and under identical zoning districts.

2.

Granting the Variance may only provide relief from standards relating to height, floor area ratio, and yard setbacks, and does not grant relief from the use limitations, minimum lot size, density requirements, or any other LCP requirements, governing the subject development.

3.

Granting the Variance does not result in special privileges inconsistent with the limitations upon other properties in the vicinity and zoning district in which the real property is located.

4.

Granting the Variance will not be detrimental to the public interest, health, safety, convenience, or welfare of the County, or injurious to the property or improvements in the vicinity and zoning district in which the real property is located.

(Ord. No. 3791, § III(Exh. A), 2023)

A.

Application. This section shall apply to: (1) any existing and lawfully established and authorized use of land; or (2) any existing and lawfully established and authorized structures, that do not conform to the policies and development standards of the certified LCP. Development that occurred after the effective date of the Coastal Act or its predecessor, the Coastal Zone Conservation Act, if applicable, that was not authorized in a Coastal Development Permit or otherwise authorized under the Coastal Act, is not lawfully established or lawfully authorized development, is not subject to the provisions of Section 20.70.160 (Nonconforming Uses and Structures), but is subject to the provisions of Section 20.70.030 (Coastal Development Permit Filing, Initial Processing).

B.

Burden to Establish Legal Status on Owner. Nonconforming uses and structures may be continued only in conformity with the provisions of this Section. The owner of property on which a nonconforming use or structure is claimed shall have the burden of proof in establishing to the satisfaction of the Director the legal nonconforming status claimed. The Director may charge a fee, as established in the County Fee Schedule, for the review of evidence submitted to meet the owner's burden of proof.

C.

Nonconforming Uses. A nonconforming use means a use of a structure or land that was legally established and maintained prior to the adoption, revision, or amendment of the Coastal Act and its predecessor statute (see Section A above) and certified LCP, but does not conform to the certified LCP use and/or density standards. A nonconforming use is not a nonconforming structure. Nonconforming uses shall not be expanded nor intensified. For non-residential uses, intensification shall include, but not be limited to, any change or expansion which is determined by the Director likely to result in a significant new or increased impact due to potential traffic generation, noise, smoke, glare, odors, hazardous materials, water use, and/or sewage generation. If any nonconforming use is abandoned for a continuous period of 12 months or longer, the use shall relinquish its legal nonconforming status and any subsequent use of such land shall be in conformity with the regulations specified by the LCP.

D.

Nonconforming Structures. A nonconforming structure means a structure that was lawfully erected prior to the adoption, revision, or amendment of the Coastal act and its predecessor statute (see Section A above) and the certified LCP, but that does not conform with standards of the LCP, including for lot coverage, setbacks, height, distance between structures, or floor area ratio prescribed in the certified LCP. Nonconforming structures may be repaired and maintained as defined in Chapter 20.130 (Coastal Zoning Code Definitions). However, replacement of 50 percent or more of the nonconforming structure is not repair and maintenance but instead constitutes a replacement structure that must be brought into conformance with the policies and standards of the LCP. The 50 percent calculation shall be cumulative, so that any repair and maintenance of a structure after the effective date of this ordinance shall be counted towards the total calculation figure. For blufftop and shoreline structures, see Subsection F, below.

E.

Additions and Improvements. Improvements which enlarge and/or expand a legal nonconforming structure, including additions, may be authorized, provided that the additions and/or improvements themselves comply with the current policies and standards of the LCP. However, improvements involving demolition and/or replacement of 50 percent or more of the existing structure, are not permitted unless the entire structure is brought into conformance with all applicable LCP policies. The 50 percent calculation shall be cumulative over time from the date of certification of this ordinance. For blufftop and shoreline structures, see Subsection F, below.

F.

Blufftop and Shoreline Development. For legal nonconforming structures located on a blufftop or along the shoreline, including such structures that are nonconforming with respect to required blufftop and shoreline setbacks, such structures may be repaired, and maintained as defined in Chapter 20.130 (Coastal Zoning Code Definitions). However, replacement of 50 percent or more of the nonconforming structure is not repair and maintenance but instead constitutes a replacement structure that must be brought into conformance with the policies and standards of the LCP.

G.

Natural Disasters. If a nonconforming use or structure is destroyed by natural disaster, replacement shall be subject to provisions of 20.68.050.C (Coastal Development Permit Not Required: Exempt Development).

(Ord. No. 3791, § III(Exh. A), 2023)

20.70.175. - Violations of Coastal Zone Regulations and Enforcement of LCP Provisions and Penalties

A.

Any person who performs or undertakes development in violation of the LCP or inconsistent with any Coastal Development Permit previously issued may, in addition to any other penalties, be civilly liable in accordance with the provisions of Public Resources Code section 30820.

B.

In addition to all other available remedies, the County may seek to enforce the provisions of the LCP and the Coastal Act pursuant to the provisions of Public Resources Code section 30800-30822.

C.

Development may only be undertaken on a legal lot.

D.

No Coastal Development Permit application (including all Coastal Development Permits, Coastal Development Permit Exclusions and Exemptions, and De Minimis Waivers) shall be approved unless all unpermitted development on the property that is functionally related to the proposed development is proposed to be removed or retained consistent with the requirements of the certified LCP.

(Ord. No. 3791, § III(Exh. A), 2023)

If the application of the policies, standards or provisions of the Local Coastal Program to proposed development would potentially constitute a taking of private property, then a development that is not consistent with the LCP may be allowed on the property to avoid a taking, provided such development is as consistent as possible with all applicable policies and is the minimum amount of development necessary to avoid a taking as determined through a takings evaluation, including an evaluation of the materials required to be provided by the applicant as set forth below. The applicant shall supplement their application materials to provide the required information and analysis as specified below.

A.

Filing. The evaluation shall, at a minimum, include the entirety of all parcels that are geographically contiguous and held by the applicant in common ownership at the time of the application. All other nearby property owned by the Applicant may also be considered. Before any decision on a Coastal Development Permit, the applicant shall provide the following information, unless the Director determines that one or more of the particular categories of information is not relevant to the analysis:

1.

The date the applicant purchased or otherwise acquired the properties, and from whom.

2.

The purchase price paid by the applicant for the properties.

3.

The fair market value of the properties at the time the applicant acquired them, describing the basis upon which the fair market value is derived, including any appraisals done at the time.

4.

The general plan, zoning or similar land use designations applicable to the properties at the time the applicant acquired them, as well as any changes to these designations that occurred after acquisition.

5.

Any development restrictions or other restrictions on use, other than government regulatory restrictions described in subsection (4) above, that applied to the properties at the time the applicant acquired it them, or which have been imposed after acquisition.

6.

Any change in the size of the properties since the time the applicant acquired them, including a discussion of the nature of the change, the circumstances and the relevant dates.

7.

A discussion of whether the applicant has sold or leased a portion of, or interest in, the properties since the time of purchase, indicating the relevant dates, sales prices, rents, and nature of the portion or interests in the properties that were sold or leased.

8.

Any title reports, litigation guarantees or similar documents in connection with all or a portion of the properties of which the applicant is aware.

9.

Any offers to buy all or a portion of the properties which the applicant solicited or received, including the approximate date of the offers and offered price.

10.

The applicant's costs associated with the ownership of the properties, annualized for each of the last five (5) calendar years, including property taxes, property assessments, debt service costs (such as mortgage and interest costs), and operation and management costs.

11.

Apart from any rents received from the leasing of all or a portion of the properties, any income generated by the use of all or a portion of the properties over the last five (5) calendar years. If there is any such income to report it should be listed on an annualized basis along with a description of the uses that generate or has generated such income.

12.

Any additional information that the County requires to make the determination.

B.

Evaluation. To evaluate whether application of the LCP would potentially result in a taking, an applicant shall provide information about coastal resources present on the properties and/or affected by the application sufficient to determine whether all of the properties, or which specific area of the properties, is subject to the restriction on development, so that the scope and nature of development that could be allowed on any portions of the properties that are not subject to the restriction can be determined.

Based upon this analysis, the least environmentally damaging feasible alternative shall be identified. Impacts to coastal resources that cannot be avoided through the implementation of siting and design alternatives shall be mitigated to the maximum extent feasible, with priority given to on-site mitigation. Offsite mitigation measures shall only be approved when it is not feasible to mitigate impacts on-site. Mitigation shall not substitute for implementation of the feasible project alternative that would avoid LCP inconsistencies, including adverse coastal resource impacts.

C.

Supplemental Findings for Approval of Coastal Development Permit. A Coastal Development Permit that allows a deviation from a policy or standard of the LCP to avoid a taking may be approved or conditionally approved only if the appropriate governing body, either the Planning Commission or Board of Supervisors, makes the following supplemental findings in addition to the findings required in Section 20.70.070 (Required Findings):

1.

Based on the information provided by the applicant, as well as any other relevant evidence, there is no potential development consistent with the LCP policies, standards and provisions that would avoid a taking of the applicant's property.

2.

The use proposed by the applicant is consistent with the applicable zoning.

3.

The use and project design, siting, and size are the minimum necessary to avoid a taking.

4.

The project is the least environmentally damaging alternative and is consistent with all provisions of the certified LCP other than the provisions for which the exception(s) is (are) necessary to avoid a taking.

5.

The development will not result in a public nuisance. If it would be a public nuisance, the development shall be denied.

(Ord. No. 3791, § III(Exh. A), 2023)

This section shall provide standards for the issuance of Coastal Development Permits for land divisions. Land division is a type of development, defined to include subdivisions (through parcel map, tract map, grant deed), lot line adjustments, and certificates of compliance.

A.

Certificates of Compliance. A conditional certificate of compliance issued pursuant to Government Code section 66499.35 shall include a condition that requires any necessary Coastal Development Permit.

B.

Criteria for Land Divisions:

1.

Land divisions shall be designed to minimize impacts on coastal resources. A land division shall not be approved if it creates a parcel that would not contain an identified building site that can be developed

consistent with all policies of the certified LCP.

2.

Land divisions outside existing developed areas shall be permitted only in areas with adequate public services, and where they will not have a significant adverse effect, either individually or cumulatively, on coastal resources. In addition, land divisions outside village limit boundaries shall only be permitted where 50 percent of the usable parcels in the area have been developed and the created parcels would be no smaller than the average size of surrounding legal parcels, except that lease of a legal parcel at a level of agricultural use that will sustain the agricultural capacity of the site is not prohibited, and lot line adjustments that do not increase potential development intensity are allowed.

3.

Land divisions shall be designed to cluster development in order to minimize site disturbance, landform alteration, and fuel modification.

4.

Land divisions are development that is not designated as the principally permitted use in any zoning district.

C.

Criteria for Lot Line Adjustments. Lot line adjustments are limited to four or fewer parcels. A Coastal Development Permit for a lot line adjustment shall not be approved or conditionally approved unless the existing parcels are legal and the new parcels resulting from the lot line adjustment will conform to the Local Coastal Program. In addition to all applicable LCP standards, a lot line adjustment shall only be approved with a finding that the resulting parcels protect coastal resources in a manner equal to or better than their existing configuration.
