Summary

It is intended to help planners identify projects that require analysis of impacts on wetland and riparian biological resources. If the project site impinges on the 300 or 500 foot buffer area, it will require further analysis of potential impacts on wetland and riparian biological resources.

Description

This layer illustrates the 300 foot boundary line in the non-Coastal area and the 500 foot boundary line in the Coastal area, around identified Ventura County water bodies, including lakes, rivers, streams, and wetlands.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Conceptual consistency
Measure description
The layer merges nine partially overlapping datasets; the Watershed Protection District's streams layer; the Public Works Agency's rivers, waterbodies, and venco layers (the venco layer, containing the County boundary, was used to derive the mean high tide line); the National Hydrographic Dataset (NHD)'s streams layer; David Magney Environmental Consulting's Vent_wtrshd_hab layer; the Santa Clara River Enhancement and Management Plan's SCREMP_Vegerac layer; the Calleguas Creek Watershed Management Plan's Calleguas_Veg1 layer; and the National Wetland Inventory's layer National_Wetlands_Inventory layer.




Data quality report - Completeness omission


Data quality report - Quantitative attribute accuracy


Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
Boundaries which follow parcel lines are accurate to within +/- 2.5 feet. Boundaries which don't follow parcel lines are accurate to within +/- 10 ft.




Lineage

Process step
Description
Created 300 and 500 foot buffer around 9 datalayers. 300 foot buffers were used in the Non-Coastal area, and 500 foot buffers in the Coastal Zone.

Title Unified Mapping System


Other citation details
The Unified Mapping System is a set of maps, drawn on U.S.G.S. 7 minute quads, including geologic/hazard information such as earthquake faults and soil types, political divisions such as School Districts and Sanitation Districts, and ecological information such as vegetation and wetland habitats. These maps were maintained and updated for use by the Planning Division, and have now been digitized as GIS layers.
