Local Area Development Guidelines

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.

Sebastopol Road Urban Vision Plan
The boundary polygon represents the Sebastopol Road Urban Vision Plan adopted by Resolution Number 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 whin 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 Mountain Development Guideline
The boundary polygon represents the Taylor-Sonoma Mountain Development Guideline adopted by Ordinance # 5131 on November 17, 1998.  

The goal of the Taylor-Sonoma Mountain Development Guideline is to reduce the visual impact of residential and related development within the area as seen from the designated scenic corridor roadways.  The guideline shall apply to single-family dwelling units, appurtenant structures and related roadways,  grading sites and utilities, except as otherwise exempt, that are or would be visible from any of the designated scenic corridor roadways.  If such a structure is not or would not be visible at the time of construction from such roadways, it is exempt from these guidelines.

Since the GIS data was developed for planning purposes and use in publication of maps and/or database creation, the data is for illustrative purpose only and is not suitable for parcel specific decision making. 

Therefore, the GIS data presented herein are approximations and further land development determination is at the discretion of the PRMD planning staff which may require a parcel specific site review (to draw parcel specific conclusions).

Creation methodology & resources:
1) refer to Data Quality - Attribute Accuracy tab for historical dataset modifications by ActiveMap version release number 
2) when incorporated (e.g. City) annexations are recorded with the County's Recorder, boundary data is modified to reflect current city boundary data - this dataset takes into account ALL RECORDED ANNEXATIONS as of 04/30/2010
3) for ActiveMap Data Capture December 2010 [ver. 2.1], rectified dataset to AM_PARCEL 10/22/2010 (modified to the borders of changed parcels & validated topology)

Note: The local area development guideline areas may cover a larger area than geographically displayed in this dataset.  The areas that cover incorporated (city) jurisdiction has been omitted from the dataset.
