    Contributors:

    Summary: This polygon shapefile represents the Sonoma County Agricultural Preservation and Open Space District's active project areas. This layer is one of seven GIS layers developed by the Sonoma County Agricultural Preservation and Open Space District for use in developing the Acquisition Plan 2000: A Blueprint for Agricultural and Open Space Preservation. This shapefile is part of a comprehensive strategy for targeting open space protection efforts in the highest priority areas. State law requires that each county and city prepare an Open Space Element as part of its General Plan that addresses how preservation of open space lands will be implemented. The 1989 Sonoma County General Plan implements legal requirements for preservation of open space land through various plan elements, including Open Space, Resource Conservation, Land Use, Public Safety, and Agricultural Resources.

  4. Title: Planning Area Policies, Sonoma County, California, 2015

    Contributors:

    Summary: The General Plan Planning Area Policy dataset represents General Plan 2020 and zoning land development policies that are applicable to (site) specific properties within Sonoma County. The intent of the plan is that policies, guidelines, and standards be clear and direct so that property owners and citizens may easily understand its provisions and how they apply to parcels of land as well as their cumulative impact on future environmental conditions and quality of life. The broad purpose of the Sonoma County General Plan is to express policies which will guide decisions on future growth, development, and conservation of resources through 2005 in a manner consistent with the goals and quality of life desired by the county's residents. Under State law many actions on private land development, such as specific plans, area plans, zoning, subdivisions, public agency projects and other decisions must be consistent with the general plan. The goals, objectives, and policies set forth in the plan will be applied in a manner to insure their constitutionality. Per Title 7, Division 1 of the Government Code of the State of California. Article 5, Section 65300 et seq, the County of Sonoma is required to adopt a comprehensive general plan to guide its future physical development. Therefore, as required by law, the 2020 Sonoma County General Plan was officially adopted on September 23, 2008 The dataset includes Rezones associated with GP2020 as adopted by Ordinance 5801 on September 23, 2008.

  5. Title: Supervisor Districts, Sonoma County, California, 2013

    Contributors:

    Summary: The board of supervisor dataset represents the five geographical sub regions of Sonoma County's legislative body which governs the largest political/jurisdictional boundary of local government within the State of California. The Board of Supervisors of the County of Sonoma is charged with the responsibility of establishing policy to guide the various functions of the County and, where necessary, to establish procedures by which functions are performed. The Board is composed of five supervisors elected from supervisorial districts for four year terms. As the county legislative body, the responsibilities of the Board of Supervisors are diverse. A major task of the Board of Supervisors is to manage the public money which comes to the county from property tax, sales tax, fees, and federal and state income grants. The Board of Supervisors is committed to providing the highest quality service to the public in a timely manner. To insure that the public is heard on issues of concern, the Board of Supervisors provides a forum for problem solving as it relates to government agencies and processes. To meet that goal, the Board also provides information and appropriate referrals to individuals who can resolve conflicts between individual citizens and the county departments. The Sonoma County Board of Supervisors sits as the governing board of Sonoma County and of various special jurisdictions such as the Sonoma County Water Agency, the Northern Sonoma County Air Pollution Control District, the Agricultural Preservation and Open Space District, County Sanitation Districts, and the Community Development Commission.

  7. Title: Planning Areas, Sonoma County, California, 2012

    Contributors:

    Summary: The planning area dataset represents the nine geographical sub regions of Sonoma County's General Plan. The General Plan consists of Land Use Elements which provides the distribution, location and extent of uses of land for housing, business, industry, open space, agriculture, natural resources, recreation and enjoyment of scenic beauty, education, public buildings and grounds, solid and liquid waste disposal facilities, and other uses. Each Land Use Element has four major sections one of which includes policies applicable for each of the 9 geographical planning areas/sub regions. Therefore, the 9 planning areas/sub regions provide the basis for geographically discreet-specific application of land use policies. Note: Specific land use policies and land use maps are representative for each of the 9 planning areas/subregions. The maps show applicable land use categories and maximum permitted density for each parcel. Further, the maps illustrate the residential density as dwellings per acre in urban residential areas and acres per dwelling in rural areas. The 9 planning areas are as follows: Area 1 - Sonoma Coast/Gualala Basin Area 2 - Cloverdale/N.E. County Area 3 - Healdsburg and Environs Area 4 - Russian River Area Area 5 - Santa Rosa and Environs Area 6 - Sebastopol and Environs Area 7 - Rohnert Park-Cotati and Environs Area 8 - Petaluma and Environs Area 9 - Sonoma Valley

  8. Title: Urban Service Areas, Sonoma County, California, 2012

    Contributors:

    Summary: The urban service area (USA) dataset represents the designated limit to the urban development of unincorporated communities per Sonoma County's General Plan 2020 as adopted on September 23, 2008 by Resolution No. 08-0808. Currently, there are 21 unincorporated urban service communities within Sonoma County. The communities are limited to urban development through urban services which is the full range of public services and infrastructures including sewer, water, police and fire protection, roads, transit, etc. Per General Plan Land Use 2020 adoption on 09/23/2008 by the Board of Supervisors, USA's were updated to reflect changes in service areas, spheres of influence and city urban growth boundaries (Reso. No. 08-0808). The 21 urban service areas are as follows: Airport Bodega Bay Cloverdale Cotati Forestville Geyserville Graton Guerneville Healdsburg Larkfield Monte Rio Occidental Penngrove Petaluma Rohnert Park Santa Rosa Sea Ranch Sebastopol Sonoma Sonoma Valley Windsor To note, according to 2012 California Environmental Quality Act (CEQA) Guidelines Chapter 2.5 Definitions addresses "Urbanized Area" and defines "urban growth boundary" as a provision of a locally adopted general plan that allows urban uses one side of the boundary and prohibits urban uses on the other side.

    Contributors:

    Summary: The General Plan Land Use by Area dataset represents the broader countywide distribution, location and extent of land development by land use categories (designation) and density as specified in the Sonoma County General Plan 2020 as adopted on September 23, 2008 by Resolution No. 08-0808. The intent of the plan is that policies, guidelines, and standards be clear and direct so that property owners and citizens may easily understand its provisions and how they apply to parcels of land as well as their cumulative impact on future environmental conditions and quality of life. The broad purpose of the Sonoma County General Plan is to express policies which will guide decisions on future growth, development, and conservation of resources through 2020 in a manner consistent with the goals and quality of life desired by the county's residents. Under State law many actions on private land development, such as specific plans, area plans, zoning, subdivisions, public agency projects and other decisions must be consistent with the general plan. The goals, objectives, and policies set forth in the plan will be applied in a manner to insure their constitutionality. Per Title 7, Division 1 of the Government Code of the State of California. Article 5, Section 65300 et seq, the County of Sonoma is required to adopt a comprehensive general plan to guide its future physical development. Therefore, as required by law, the 2020 Sonoma County General Plan was officially adopted on September 23, 2008.

  10. Title: Zoning, Sonoma County, California, 2012

    Contributors:

    Summary: The zoning by area dataset represents the detailed countywide distribution, location and extent of land development by base zoning districts, density and parcel specific combining districts (P, TS, Z) as specified in Sonoma County Code Zoning Regulations Chapter 26. Chapter 26 has been adopted to promote and protect the public health, safety, peace, comfort, convenience and general welfare. It is also adopted for the following specified purposes: (a) To provide for the orderly and beneficial land use of the county; (b) To protect the character and social and economic stability of agricultural, residential, commercial, industrial and other communities within the county; (c) To protect the public safety and welfare by regulating the location and uses of all structures and land; (d) To protect and conserve the scenic, recreational and natural resource characteristics of the county; (Ord. No. 2392, 4) (e) To provide for the orderly and timely processing of development projects as anticipated by the California Permit Streamlining Act. Development projects do not include rezoning, plan amendments or other applications accompanied by a request for a rezoning or plan amendment. (Ord. No. 4643, 1993.) Chapter 26 specifies the applicability of base zoning districts to general plan land use categories (designations). Therefore, base zoning districts and the general plan land uses are interdependent. While the general plan land use specifies broader land use development policies, guidelines, and standards, each base zoning district is specific in stating purpose, permitted uses, uses permitted with a use permit and permitted residential density and development criteria.

  12. Title: Local Area Development, Sonoma County, California, 2012

    Contributors:

    Summary: The local area development guideline dataset represents the discreet geographical areas subject to specific development guidelines within Sonoma County. The local area development guidelines and goals are as follows: Canon Manor West Subdivision Development Guideline The boundary polygon represents the Canon Manor West Subdivision Development Guideline, 237+/- acres located southwest of the intersection of Petaluma Hill Road and East Cotati Avenue, adopted by Ordinance #5675 & #5676 on July 18, 2006. The Canon Manor West Subdivision Development Guideline boundary surrounds those parcels subject to water conservation measures as described in Ordinance #5676. To note, Ordinance #5675 outlines the approved rezoning of the subject area [refer to adopted documentation for further insight]. - - - - Glen Ellen Development and Design Guideline, Subarea I & II The boundary polygon represents the Glen Ellen Development and Design Guideline adopted by Ordinance #4297 on November 14, 1990. The Glen Ellen Development and Design Guidelines boundary surrounds those parcels within subareas I and II of the Glen Ellen Study Area. The following applications within the subareas shall be evaluated in accordance with the Glen Ellen Development and Design Guidelines: Subarea I (exterior building permits, discretionary permits, and projects subject to administrative design review), and Subarea II (discretionary permits). The goal of the Glen Ellen Development and Design Guidelines is to direct development so that the character of Glen Ellen is enhanced and maintained. The guideline defines a local area, as a subunit of a planning area, which will provide a greater level of detail for specific uses or development in a local area. The Glen Ellen Development and Design Guidelines represent revised goals, objectives, policies and design guideline contained in previous versions of the Glen Ellen Town Plan (February 1988 and November 1988). - - - - Highway 12 Development Guideline The boundary polygon represents the Highway 12 Development Guideline adopted by Ordinance #5120 on August 25, 1998. The Highway 12 Development Guideline is applicable to parcels having frontage on Highway 12 from its intersection at El Verano Avenue, north, to its intersection at Agua Caliente Road. The Highway 12 Development Guideline is in conjunction with the Sonoma Valley Redevelopment Project Area. The goal of the Highway 12 Development Guideline is to provide criteria for private development to ensure the consistency of each individual project with the overall character of the Hwy 12 corridor. - - - - Highway 116 Scenic Corridor Study Guideline The boundary polygon represents the 116 Scenic Highway Corridor Study Guideline adopted by the State of California's Department of Transportation (Caltrans) on September 20, 1988. The goal of the 116 Scenic Highway Corridor Study is to protect and enhance the corridor. Therefore, the corridor limits are principally determined by topography (land forms) and/or large, dense stands of vegetation limiting views from the highway. If vegetation or man-made structures do not obstruct views from the highway, the farthest ridge lines are the limits of the corridor. Only those ridges visible from the corridor are included; consequently, areas behind ridges are not included. The width of the corridor varies greatly from as little as 100 feet to as much as 14,000 feet. Property within the corridor could be subject to higher levels of planning controls to preserve the scenic quality. - - - - Penngrove Main Street Design Guidelines The boundary polygon represents the Penngrove Main Street Design Guidelines adopted by Ordinance #5920 on December 14, 2010. The goal of the Penngrove Main Street Design Guidelines is to evaluate the merits of projects located in and around Main Street in Penngrove, between Old Redwood Highway and Adobe Road, and as specifically depicted by Figure E of Ordinance # 5920 article. Building permits involved new construction, or the exterior modification of existing structures, are subject to review to ensure conformance with the Penngrove Main Street Design Guidelines. In addition, all projects requiring discretionary entitlements, such as Design Review approval, Zoning Permits, and Use Permits, must comply with the Penngrove Main Street Design Guidelines. - - - - Russian River Corridor Design Guidelines The boundary polygon represents the Russian River Corridor Design Guidelines adopted by Ordinance #5921 on December 14, 2010. The goal of the Russian River Corridor Design Guidelines is to evaluate the merits of projects located within the central corridor which runs through the Russian River Redevelopment Project Area, and as specifically depicted in Figure A of Ordinance #5921 article. The Russian River Corridor Design Guidelines apply to commercial and multi-family residential projects. Single family projects are only subject to the Design Guidelines when involving four or more units. Building permits involving new construction, or any exterior modification of existing structures, are subject to review to ensure conformance with the Russian River Corridor Design Guidelines, as are all projects which require discretionary entitlements such as Design Review, Zoning Permits, and Use Permits. - - - - Sebastopol Road Urban Vision Plan The boundary polygon represents the Sebastopol Road Urban Vision Plan adopted by Resolution #07-0481 on October 31, 2007. The Urban Vision Plan for Sebastopol Road Corridor affects that stretch of Sebastopol Road between Dutton Avenue to the east and Stony Point Road to the west, linking both sides of Sebastopol Road as well as the area north of Sebastopol Road, ending at the Highway 12 right-of-way. The corridor is within the community of Roseland in the southwest area of Santa Rosa, California. While portions of the subject area are within the boundaries of the City of Santa Rosa, the majority of the properties are located in the unincorporated area of Sonoma County. The goal of the Sebastopol Road Urban Vision Plan is to create a consensus among the local community as to what future development of the corridor should look like and what types of uses should be located there. The goal includes land use concept and urban design criteria for the greater planning area, street scape enhancements, and envisioning the Roseland Village Shopping Center and the Dutton Plaza as an ideal location for a neighborhood center. - - - - Taylor/Sonoma/Mayacamas Design Guidelines The boundary polygon represents the Taylor/Sonoma/Mayacamas Design Guidelines adopted by Ordinance #5935 on May 10, 2011. The adoption amends Section 26-90-050 of the Sonoma County code to replace the existing Taylor-Sonoma Mountain Development Guidelines due to following General Plan scenic landscape units. The boundary polygon was revised with Resolution #11-0462 adopted August 23, 2011. The goal of the Taylor-Sonoma Mountain Development Guideline is to reduce the visual impacts of residential related development within the Scenic Landscape Units of Taylor, Sonoma, and Mayacamas areas as visible from public roads.

  13. Title: Parcels, Sonoma County, California, 2012

    Contributors:

    Summary: The parcel dataset represents ONLY unincorporated Sonoma County land and takes into account ALL RECORDED ANNEXATIONS as of December 31, 2012. The parcel dataset is based on an original parcel base obtained from the County of Sonoma, ISD/GIS (a.k.a. Central GIS). Due to the sensitive nature of land development datasets maintained by Sonoma County Permit and Resource Management Department [PRMD], only those parcels which have been reassigned a parcel number [APN] or have been reconfigured due to lot line adjustments, subdivision and/or merger/splits, are updated by PRMD GIS staff. [Note: Should you wish to obtain Central GIS, a non-ActiveMap/PRMD, parcel base dataset, please research vector data download link https://gis.sonoma-county.org/catalog.asp.] A distinction should be made with respect to this layer which includes GIS parcels and the official Assessor Parcels residing in the Assessor Map books at the Sonoma County Assessor Office. For official parcel records please contact the Sonoma County Assessor (707)565-1888. These parcels should NOT be represented as survey data, and the official record of survey takes precedence where there are discrepancies. It is the end user's responsibility to check the accuracy of the GIS data by comparing it with the published data from the Sonoma County Assessor / Recorder office. The Sonoma County parcel base was originally compiled from Assessor Parcel maps at a scale of 1:6000. The individual Assessor Parcel maps were enlarged or reduced in size using an electrostatic process to produce the maps at the 1:6000 scale, the maps were then fit together by hand and transcribed on to mylar. The mylar base consisted of 1:6000 USGS base map information typically found on the 7.5 USGS quad series. This base information consisted of Topography, Roads, Section, and Rancho lines to name some. Using this information, the Assessor Parcel maps were fit to the individual 1:6000 scale maps. Each 1:6000 scale map represents 1/6 (quad sixths) of a 7.5 minute USGS Quadrangle series map. In 1998 the State Board of Equalization provided the impetus to produce the Russian River Project for all of Planning Area 4. One aspect required for this project was a digital parcel base for Planning Area 4. This involved the conversion of the 1:6000 mylars with the transcribed parcels on them into a digital version of the parcels. The mylars where scanned and geo-referenced using the base map information originally included with the 1:6000 mylar base. The maps were geo-referenced to a digital version of the USGS 7.5 minute Quadrangle series available from the Teale Data Center. The original projection was California State Plane Zone 2 NAD 1927. County Staff then used AutoCAD software to heads up digitize each 1:6000 scale map in Planning Area 4. A custom application was created and used by GIS staff involving the use of Avenue and ArcView 3.2 to create a point for all the parcels in Planning Area 4, attributes included Assessor Parcel Number. The DWGs were then converted to shapefiles and then converted to ArcINFO coverages, the parcel tags were converted from shapefiles to ArcINFO coverages and the point coverage was merged with the polygon coverage with the IDENTITY command. An exhaustive process was involved to eliminate errors once the DWGs were converted to ArcINFO coverages so polygons could be generated. The coverages were then aggregated using the MAPJOIN command, the original boundary of the 1:6000 scale maps was removed using the REGIONDISSOLVE command to merge adjacent polygons with the same AP number. In 1999 the remainder of the planning areas were converted to digital form following the Russian River Project and the seamless base was completed in 2001. The seamless parcel base was maintained in ArcINFO until the release of ArcGIS 8.3, which included topology tools necessary for its maintenance. The seamless base prior to late 2002 was suitable for 1:100000 scale while the control points (the corners for the 1:6000 scale maps) were suitable for 1:24000 scale. Prior to rectification to the Merrick 2000 orthophotography, the parcel data were derived from 1:6000 scale maps (enlarged from USGS 7.5 minute quadrangle 1:24,000 series) and digitized in California State Plane, Zone II, NAD 27 coordinates (survey feet), but were converted to California State Plane, Zone II, NAD 83 coordinates (survey feet) as part of a rectification process now underway. The parcels used to use the USGS 7.5 minute quadrangle (1:24,000) series for coordinate control, but no guarantee is made for their spatial accuracy. The data were re-projected to NAD 83 coordinates to overlay the orthophotography, but the parcel boundaries will not correspond precisely with features in the images. The parcels were rectified to orthophotography flown in April - May 2000 using geo-referencing tools available in ArcGIS 8.3. This project was completed in July 2005. In general, the parcels meet National Accuracy Standards for 1:24,000 scale maps, and likely exceed that accuracy in urban areas. A complete description of the process is detailed in a series of documents located on a local file server: S:\COMMON\GIS\Documentation\Parcel Rectification & Update Process\Procedure - *. doc. A brief summary is as follows. Individual Assessor Parcel pages or CAD drawings are rectified to the orthophoto. COGO & survey data are used when available and in sufficient quantities to enable the bulk of an Assessor Parcel page to be digitized using said information. Polygons are generated directly from the COGO data, CAD dwg are exported to feature classes, where polygons are then generated, rectified Assessor Parcel pages are vectorized using ArcScan and subsequently polygons are generated. A spatial join is used to assign attributes to the newly generated polygons. Polygons are then assigned an accuracy rank based on source, quality of the fit to the orthophoto, and RMS error encountered during rectification (only the scanned Assessor maps will have and RMS error associated with them). See the fields RANK and DESCRIPTION for information on fit assessment. Areas that have been successfully updated as such have a reasonable expectation of accuracy of +/- 10 and possibly better, areas that have not been updated or are flagged in SCAMP (http://sc-gis/web/scamp/browse.jsp) under the GIS group Projects as Needs Survey Data, the original accuracy assessment of 1:100000 applies.

  14. Title: Scenic Corridors, Sonoma County, California, 2011

    Contributors:

    Summary: The scenic corridors dataset represents the Open Space and Resource Conservation Scenic Resources Element 2.3 of the Sonoma County General Plan 2020 as adopted on September 23, 2008 by Resolution No. 08-0808. The scenic corridors element assist in identifying and preserving roadside landscapes that have a high visual quality as they contribute to the living environment of local residents and to the County's tourism economy. The scenic corridors represent one of three scenic resources component categories of the Sonoma County General Plan 2020 Open Space and Resource Conservation Element. The other scenic resource categories are Scenic Landscape Units and Community Separators. The Figure OSRC-1 (http://www.sonoma-county.org/prmd/gp2020/adopted/fig-osrc1.pdf) shows these designated scenic resource areas. The intent of the plan is that policies, guidelines, and standards be clear and direct so that property owners and citizens may easily understand its provisions and how they apply to parcels of land as well as their cumulative impact on future environmental conditions and quality of life. The broad purpose of the Sonoma County General Plan is to express policies which will guide decisions on future growth, development, and conservation of resources through 2020 in a manner consistent with the goals and quality of life desired by the county's residents. Under State law many actions on private land development, such as specific plans, area plans, zoning, subdivisions, public agency projects and other decisions must be consistent with the general plan. The goals, objectives, and policies set forth in the plan will be applied in a manner to insure their constitutionality. Per Title 7, Division 1 of the Government Code of the State of California. Article 5, Section 65300 et seq, the County of Sonoma is required to adopt a comprehensive general plan to guide its future physical development. Therefore, as required by law, the 2020 Sonoma County General Plan was officially adopted on September 23, 2008.

  15. Title: Redevelopment Plans, Sonoma County, California, 2010

    Contributors:

    Summary: The redevelopment plan dataset represents the three designated project areas governed by the Sonoma County Community Development Commission. Redevelopment agencies exercise governmental functions and powers under the provisions of the Community Redevelopment Law (CRL), Health and Safety Code Sections 33000 et seq. of the State Constitution. Enacted shortly after the end of World War II, refined over the decades and tested in the courts, the CRL has provided a means by which cities and counties can address deteriorating physical, economic and social conditions in urbanized areas at the local level. It has become a primary tool for rehabilitation of housing stock, revitalization of business environments, creation of jobs, and for gaining the participation and investment of the property owners, business owners and residents of designated project areas. Through redevelopment, a project area will receive focused attention and financial investment to reverse deterioration trends in areas where the private sector is less inclined to invest without government assistance. A redevelopment agency must establish a designated project area before it can undertake any of the activities allowed under the CRL. Sonoma County established its Community Redevelopment Agency in 1984 and, later the same year, completed the process of designating its first two project areas; the Roseland and The Springs (Sonoma Valley) project areas. The County's newest project area on the lower Russian River was approved in July of 2000. The redevelopment plans and goals are as follows: Roseland Redevelopment Plan The boundary polygon represents the Roseland Redevelopment Plan adopted by Resolution # 84-2347 on November 27th, 1984. The primary objective of the Roseland Plan has been to improve the area's infrastructure, primarily Sebastopol Road. The Project's focus is now being turned to affordable housing and mixed-use development opportunities. - - - - Russian River Redevelopment Plan The boundary polygon represents the Russian River Redevelopment Plan adopted by Resolution # 5249 on July 18th, 2000. The Russian River Redevelopment Plan states twenty-three Specific Goals and Objectives that include: restoration and expansion of the Project Area as a desirable visitor and tourist destination; revitalization, as appropriate, of the Project Area's businesses and business districts; enhancement and protection of the physical environment and sensitive habitat areas; preservation and enhancement of architecturally and historically interesting buildings and neighborhoods; improvement of substandard housing conditions; improvement of streets to ensure safe motor vehicle, bicycle and pedestrian movements; upgrading and improvement of utility services to reduce power outages; assistance in the repair, expansion or development of sewer facilities; and assistance to public safety entities in the provision of capital facilities and equipment to serve the Project Area and environs. - - - - The Springs (Sonoma Valley) Redevelopment Plan The boundary represents the The Springs (Sonoma Valley) Redevelopment Plan adopted by Resolution # 84-3379 on November 27th, 1984. The Springs (Sonoma Valley) Redevelopment Plan has three primary Goals: 1. Create for the Sonoma Highway commercial district an efficient, attractive and identifiable commercial neighborhood in which existing and new commercial establishments and professional offices can capture a share of the growing market demand for goods and services in the area. 2. Alleviate deterioration in residential neighborhoods in order to stabilize and enhance the quality of the Project Area neighborhoods. 3. Maximize the natural environmental potential of the Project Area in order to create an attractive and efficient community for all persons working and living in the area.

  16. Title: Scenic Landscape, Sonoma County, California, 2010

    Contributors:

    Summary: The scenic landscape unit's dataset represents the Open Space and Resource Conservation Scenic Resources Element 2.2 of the Sonoma County General Plan 2020 as adopted on September 23, 2008 by Resolution No. 08-0808. This dataset includes additions to the Scenic Landscape Units as of August 23, 2011 per Resolution #11-0463. As the County urbanizes, the scenic landscape unit element assists in identifying areas that require the maintenance of openness for visual relief from urban densities/development. The scenic landscapes units have little capacity to absorb substantial development without significant visual impact and this element assist in retaining the largely open, scenic character of these landscapes. Therefore, the preservation of these scenic resources is important to the general welfare and quality of life for County residents while maintaining the tourists and agricultural economy within the 15 major scenic landscape units designated. The scenic landscape units represent one of three scenic resources component categories of the Sonoma County General Plan 2020 Open Space and Resource Conservation Element. The other scenic resource categories are Community Separators and Scenic Corridors. The Figure OSRC-1 (http://www.sonoma-county.org/prmd/gp2020/adopted/fig-osrc1.pdf) shows these designated scenic resource areas. The major Scenic Landscape Units have been identified as follows: The Coast Oak Valley Alexander and Dry Creek Valleys Hills East of Windsor Eastside Road River Road Laguna de Santa Rosa Bennett Valley Highway 116 Atascadero Creek Coleman Valley Sonoma Mountains Hills South of Petaluma Sonoma Valley/Mayacamas Mountains South Sonoma Mountains The intent of the plan is that policies, guidelines, and standards be clear and direct so that property owners and citizens may easily understand its provisions and how they apply to parcels of land as well as their cumulative impact on future environmental conditions and quality of life. The broad purpose of the Sonoma County General Plan is to express policies which will guide decisions on future growth, development, and conservation of resources through 2020 in a manner consistent with the goals and quality of life desired by the county's residents. Under State law many actions on private land development, such as specific plans, area plans, zoning, subdivisions, public agency projects and other decisions must be consistent with the general plan. The goals, objectives, and policies set forth in the plan will be applied in a manner to insure their constitutionality. Per Title 7, Division 1 of the Government Code of the State of California. Article 5, Section 65300 et seq, the County of Sonoma is required to adopt a comprehensive general plan to guide its future physical development. Therefore, as required by law, the 2020 Sonoma County General Plan was officially adopted on September 23, 2008.

  17. Title: Marshes and Wetlands, Sonoma County, California, 2010

    Contributors:

    Summary: The marshes and wetlands dataset represents the Open Space and Resource Conservation Biotic Resources Habitat Areas Element 3.1 of the Sonoma County General Plan 2020 as adopted on September 23, 2008 by Resolution No. 08-0808. The marshes and wetlands is one of four types of biotic habitats which assist in identifying and preserving natural and diverse biotic resource habitat areas from adverse effects of human activities. The Wetlands are transitional areas between aquatic and terrestrial habitats and include marshes, vernal pools, seeps, springs, and portions of riparian corridors with wetland vegetation. Wetlands are recognized for their high fish and wildlife habitat values, occurrences of unique plant and animal species, and importance in water recharge and filtration. Wetlands meeting certain criteria are subject to regulations of the US Army Corps of Engineers, US Fish and Wildlife Service (USFWS), CDFG, or applicable Regional Water Quality Control Boards. Wetland areas mapped as part of the National Wetlands Inventory and other sources include the Laguna de Santa Rosa, vernal pools, San Pablo Bay and Petaluma marshes, coastal and tidal marshes, and such freshwater marshes as the Pitkin, Kenwood, Cunningham, and Atascadero Marshes. Detailed delineations are typically necessary to confirm the presence and extent of any jurisdictional wetlands. The Biotic Habitat Areas designated on Figures OSRC-5a through 5i (http://www.sonoma-county.org/prmd/gp2020/adopted/index.htm) depict the habitats whose locations are known and considered important for protection at this time. However, the biotic habitat policies provide for protection of biotic habitats both within and outside designated areas. Currently available information on the location and value of native habitats and sensitive resources is incomplete and changes over time as sites are assessed, new occurrences are reported, and additional locations are identified. As more habitat mapping information becomes available in the future, changes in designations will be considered along with possible policy changes. Regular collection and updating of reliable information and refinement of best management practices are necessary to protect the County's biotic resources over the long term. The intent of the plan is that policies, guidelines, and standards be clear and direct so that property owners and citizens may easily understand its provisions and how they apply to parcels of land as well as their cumulative impact on future environmental conditions and quality of life. The broad purpose of the Sonoma County General Plan is to express policies which will guide decisions on future growth, development, and conservation of resources through 2020 in a manner consistent with the goals and quality of life desired by the county's residents.

  18. Title: Population Density in Watersheds: San Francisco Bay Area, California, 2009

    Contributors:

    Summary: This polygon shapefile depicts a watershed integrity cluster analysis at the CalWater 2.2.1 Planning Watershed (PWS) level performed by mapping factors representing some of the most significant watershed threats. Each of the individual watershed integrity factors was individually mapped and then combined in the watershed cluster analysis. This individual threat, cultivated, was created by taking CalWater watersheds at the planning unit level (most refined) and running zonal stats, part of spatial analyst. The Calwater PWS watershed was the zone dataset (pwsname as the zone field) and Population Density as the value raster. The result gives you the mean percent population density of the nine county San Francisco Bay Area Region, California at the watershed level in a table that you can join back to the CalWater GIS layer and then symbolize as a graduated color with the mean being the value field. This analysis was done by the Conservation Lands Network Fish and Riparian Focus Team. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships. The Conservation Lands Network GIS Database is the primary output of the Project. The data depicts the spatially explicit CLN that is recommended for the nine county San Francisco Bay Area Region, California.

  20. Title: Winter Steelhead Distribution: San Francisco Bay Area, California, 2007

    Contributors:

    Summary: The data was clipped to the Bay Area. Winter Steelhead Distribution (CalFish) June 2007 Version This polyline shapefile depicts observation-based, stream-level geographic distribution of anadromous steelhead trout (Oncorhynchus mykiss irideus) during winter months in the nine county San Francisco Bay Area Region, California. It was developed for the express purpose of assisting with steelhead recovery planning efforts. The distributions reported in this dataset were derived from a subset of the data contained in the Aquatic Species Observation Database (ASOD), a Microsoft Access multi-species observation data capture application. ASOD is an ongoing project designed to capture as complete a set of statewide inland aquatic vertebrate species observation information as possible. ASOD observation data were used to develop a network of stream segments. These lines are developed by "tracing down" from each observation to the sea using the flow properties of United States Geological Survey National Hydrography Dataset (NHD) High Resolution hydrography. Lastly these lines, representing stream segments, were assigned a value of either Anad Present (Anadromous present) or Unsp Present (Unspecified O. mykiss present). The resulting layer consists of a set of lines representing the winter distribution of steelhead. This dataset represents stream reaches that are known or believed to be used by steelhead based on steelhead observations, thus, it contains only positive steelhead occurrences. The absence of distribution on a stream does not necessarily indicate that steelhead do not utilize that stream. Additionally, steelhead may not be found in all streams or reaches each year. This is due to natural variations in run size, water conditions and other environmental factors. The information in this dataset should be used as an indicator of steelhead presence/suspected presence at the time of the observation as indicated by the 'Late_Yr' (Latest Year) field attribute. The line features in the dataset may not represent the maximum extent of steelhead on a stream; rather it is important to note that this distribution most likely underestimates the actual distribution of steelhead. The individual observations may not have occurred at the upper extent of anadromous occupation. In addition, no attempt was made to capture every observation, so it should not be assumed that this dataset is complete for each stream. No additional data (habitat mapping, barriers data, gradient modeling, etc.) were utilized to either add to or validate the data. It is very possible that an anadromous observation in this dataset has been recorded above (upstream of) a barrier as identified in the Passage Assessment Database (PAD). In the future, we hope to perform a comparative analysis between this dataset and the PAD to identify and resolve all such discrepancies. Such an analysis will add rigor to and help validate both datasets. This dataset has recently undergone a review. Data source contributors as well as California Department of Fish and Wildlife (CDFW) fisheries biologists were provided the opportunity to review and suggest edits or additions during the review. Initially, data contributors were notified and invited to review and comment on the handling of the information that they provided. The distribution was then posted to an intranet mapping application and CDFW biologists were provided an opportunity to review and comment on the dataset. During this review, biologists were also encouraged to add new observation data. This resulting final distribution contains their suggestions and additions. Please refer to "Use Constraints" section below.
