Zoning in California, including Mariposa County, plays a crucial role in land use management and development regulation. Zoning ordinances categorize different areas of land into specific zones or districts, each with designated permitted uses, density regulations, building heights, and other development standards. In Mariposa County, zoning ensures orderly growth, protects natural resources, and preserves the county's unique character and rural landscape. By defining where residential, commercial, industrial, agricultural, and recreational activities can occur, zoning helps balance community needs, promote public safety, and maintain property values. It also provides a framework for local governments to implement long-term planning goals, such as promoting sustainable development, preserving open spaces, and supporting economic vitality. Zoning ordinances are crafted with input from community stakeholders and are periodically updated to reflect changing demographics, economic conditions, and environmental concerns, ensuring that Mariposa County continues to grow and evolve responsibly while preserving its quality of life and natural beauty.Click the link below to view the Mariposa County Code Title 17 Section about Zoning.https://mariposa.municipalcodeonline.com/book?type=ordinances#name=Title_17_Zoning

Mariposa County organizationally shared view layer of daily parcels updates. County owned and Public/Quasi-Public (County of Mariposa, Mariposa Unified School District, MPUD) parcels. Mariposa County occasionally partakes in the purchase or sale of land. This map is intended to allow the public to maintain awareness of the land the County owns.

The General Plan creates the land use classification "planning area." Planning areas identify "towns," "communities," and "special" planning areas. Planning areas are implemented by area plans adopted by the Board of Supervisors. "Area plans" are mini-General Plans adopted to meet the needs of each town, community, or uniquely identified special area of the County.The towns of Mariposa, Coulterville, Fish Camp and Wawona each have adopted "town planning area specific plans." Catheys Valley has adopted a "community plan." These plans will remain in effect and are incorporated in Volume II of the General Plan as the community's area plans, though modifications or updates may be necessary to consider Planning Study Areas adjacent to the communities or address new policies. For Mariposa and Coulterville, the name of the plan changed from "specific plan" to "town plan." For Fish Camp and Wawona, the name of the plan remained "town planning area specific plan." Catheys Valley did not change, and became a "community plan" in December 2012.Town planning areas represent the rural scale "urban" development centers for the County. Town planning areas are specifically designated as locations in the County where policy mandates a broad and comprehensive mixture of land uses and zoning. A mixture of housing types and styles for all economic segments of the County are disbursed throughout the town planning areas.Community planning areas or special planning areas represent separate policy approaches. A planning area's character and values are generally based in the character of the General Plan land use classifications in which it is situated. At the policy level, area plans are developed specifically to reflect community values.For more information visit Planning Area Land Use Classification | Mariposa County, CA - Official Website

The 1998 Mariposa County land use survey data set was developed by DWR through its Division of Planning and Local Assistance (DPLA). The data was gathered using aerial photography and extensive field visits, the land use boundaries and attributes were digitized, and the resultant data went through standard quality control procedures before finalizing. The land uses that were gathered were detailed agricultural land uses, and lesser detailed urban and native vegetation land uses. The data was gathered and digitized by staff of DWR’s San Joaquin District. Quality control procedures were performed jointly by staff at DWR’s DPLA headquarters and San Joaquin District. The finalized land use vector data is a single, polygon, shapefile format. Important points about using this dataset: 1. The land use boundaries were hand drawn directly on USGS quad maps and then digitized. They were drawn to depict observable areas of the same land use. They were not drawn to represent legal parcel (ownership) boundaries, or meant to be used as parcel boundaries. 2. This survey was a "snapshot" in time. The indicated land use attributes of each delineated area (polygon) were based upon what the surveyor saw in the field at that time, and, to an extent possible, whatever additional information the aerial photography might provide. For example, the surveyor might have seen a cropped field in the photograph, and the field visit showed a field of corn, so the field was given a corn attribute. In another field, the photograph might have shown a crop that was golden in color (indicating grain prior to harvest), and the field visit showed newly planted corn. This field would be given an attribute showing a double crop, grain followed by corn. The DWR land use attribute structure allows for up to three crops per delineated area (polygon). In the cases where there were crops grown before the survey took place, the surveyor may or may not have been able to detect them from the field or the photographs. For crops planted after the survey date, the surveyor could not account for these crops. Thus, although the data is very accurate for that point in time, it may not be an accurate determination of what was grown in the fields for the whole year. If the area being surveyed does have double or multicropping systems, it is likely that there are more crops grown than could be surveyed with a "snapshot". 3. If the data is to be brought into a GIS for analysis of cropped (or planted) acreage, two things must be understood: a. The acreage of each field delineated is the gross area of the field. The amount of actual planted and irrigated acreage will always be less than the gross acreage, because of ditches, farm roads, other roads, farmsteads, etc. Thus, a delineated corn field may have a GIS calculated acreage of 40 acres but will have a smaller cropped (or net) acreage, maybe 38 acres. b. Double and multicropping must be taken into account. A delineated field of 40 acres might have been cropped first with grain, then with corn, and coded as such. To estimate actual cropped acres, the two crops are added together (38 acres of grain and 38 acres of corn) which results in a total of 76 acres of net crop (or planted) acres. 4. Water source information was not collected for this survey. 5. Not all land use codes will be represented in the survey.

17.64.010 Airport Overlay (APO)The Airport Overlay (APO) is an overlay district and is intended to create airport approach zoning regulations for the purpose of promoting the health, safety and general welfare of inhabitants of the county by preventing the creation or establishment of airport hazards, and thereby protecting the lives and property of users of a county airport and of occupants of the land in the vicinity of a county airport and preventing destruction and impairment of the utility of an airport and any public investment therein. Within any specific APO the specific policies, standards and regulations of the Principle Zone with which the APO is combined, are modified in accordance section 17.64.010.A - J below. Development standards for APO. Development standards for the APO shall be as follows: Uses: Permitted uses: In addition to the uses allowed by the principal zone the following additional land uses shall be permitted on the airport property, subject to conformity with Federal Aviation Agency (FAA) standards applicable to the particular airport property: Accessory structures and facilities, including aircraft and aviation accessory sales; Aircraft fueling facilities; Aircraft storage, service, and repair hangars; Lighting, radio, and radar facilities; Runways, taxiways, landing strips, and aprons, grassed or paved; Terminal facilities for passengers and freight. Conditional uses: None.Prohibited uses: The uses permitted by the principal zone shall be modified as follows: Zone A: No structures are allowed; Zone B: No industries involved in flammable materials or processes, major public utility distribution centers, or places intended for the general public to gather in which a population density of greater than 50 persons per acre will occur (including hotels, motels, restaurants, bars, churches, schools, hospitals, government services, concert halls, auditoriums, stadiums, arenas, or other uses) are allowed. Maximum structural coverage shall not exceed 50% of the total land area. Clustering of development is encouraged to avoid placing structures within the zone. Zone C: Residential uses and places of public assembly should be clustered so as to avoid placing structures under the most heavily used flight patterns; (A map showing properties within the Zones A, B, and C is available for public review in the office of the Mariposa County planning department.) Minimum parcel or lot size: Same as the principal zone. Density: Same as the principal zone. Use limitations. No use may be made of land within any primary surface, horizontal surface, conical surface, or transition surface, in such a manner as to create electrical interference with radio communication between the airport and aircraft; make it difficult for pilots to distinguish between airport lights and other lights, use lights which will produce glare in the eyes of the pilots using the airport, impairing pilot visibility, or otherwise endangering the landing, takeoff or maneuvering of aircraft. Airport Surfaces. In order to carry out the purpose of this chapter, all land within the boundaries of the Mariposa- Yosemite Airport, and other land in the vicinity of the airport is divided into: horizontal surfaces, conical surfaces, transitional surfaces, approach surfaces and primary surfaces, the boundaries of which are on a map designated as the Mariposa- Yosemite Airport surfaces map. The Mariposa-Yosemite Airport surfaces map shall be maintained in the Mariposa County planning department and available for public examination. Definitions. Due to the unique character of the district, the following definitions shall apply to the provisions contained in this Chapter and shall not affect or otherwise alter any other provisions of this Title: Airport: The Mariposa-Yosemite Airport. Airport hazard: Any structure or tree or use of land which obstructs the airspace required for the flight of aircraft in landing or taking off at the airport, or is otherwise hazardous to such landing or takeoff of aircraft. Landing area: The area of the airport used for the landing, takeoff, or taxiing of aircraft. Structure airport: Any object constructed or installed by man, including but not limited to buildings, towers, smokestacks, and overhead lines. Tree: Any object of natural growth. Imaginary Surface: A horizontal surface above which objects affect navigable airspace. The imaginary surface is established at the 2,402 feet mean sea level. Primary Surface: A horizontal surface that extends 200 feet beyond each end of the runway. The elevation at any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.Transition Surface: Laterally from the primary surface to the distance where a one hundred fifty (150) foot height above the primary surface is reached on a 7:1 slope: one hundred fifty (150) feet at the outer perimeters. Horizontal Surface: The horizontal surface is established by swinging arcs five thousand (5000) feet radii from the center of the ends of the primary surface, and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone shall encompass the area from the outer perimeter of the transition surface to the limits of the five thousand (5000) foot radii and tangents: the elevation of the horizontal surface shall be one hundred fifty (150) feet at all locations. Conical Surface: Outward from the outer perimeter of the horizontal surface a distance of four thousand (4000) feet on a 20:1 slope: one hundred fifty (150) foot elevation at the inner perimeter to three hundred fifty (350) foot elevation at the outer perimeter. Approach Surface: From the edge of the clear zone at the ends of the runway a distance required to intersect the horizontal zone at a 20:1 slope with the outer edges sloping outward at a 10:1 slope: one hundred fifty (150) feet at the outer perimeter. Height limits. In order to protect the safety of aircraft as well as facilities on the ground the following height limitations are imposed. In areas in which the ground surface lays below the imaginary surface the height of all structures shall be limited to the elevation of the imaginary surface or 35 feet, whichever is less. In areas in which the ground surface penetrates the imaginary surface the height of all structures shall be limited to 35 feet. Exception to height limitations. Nothing in this section shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to twenty-five (25) feet above the surface of the land except in the primary surface.Multiple coverage: Where an area is covered by more than one (1) height limitation, the more restrictive limitations shall prevail except as provided for in item F. Noise standards: New residential development and major renovations to existing residential development (exceeding 50% of the value of the existing dwelling) located within the future (2010) 60-65 CNEL contours (as contained in the Mariposa-Yosemite Airport Comprehensive Land Use Plan) shall provide a noise analysis of their project site to determine the level of noise insulation required to reduce the indoor noise levels to below 45 CNEL and shall incorporate the noise insulation into dwelling construction. The Mariposa-Yosemite Airport noise map shall be maintained in the Mariposa County planning department and available for public examination. Amendments to general plans, specific plans, and zoning ordinances: Any proposed amendment to a general plan, specific plan, or zoning ordinance that affects land uses within the airport influence area boundary must be submitted to the ALUC for a determination of consistency with the Airport Land Use Plan. The ALUC shall provide its findings regarding project consistency to the county reviewing authority prior to public hearings on the project.
