Name: Los Angeles County Flood Control District Boundary
Display Field: BNDRY_NAME
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The Flood Control District encompasses more than 3,000 square miles, 85 cities and approximately 2.1 million land parcels. It includes the vast majority of drainage infrastructure within incorporated and unincorporated areas in every watershed, including 500 miles of open channel, 2,800 miles of underground storm drain, and an estimated 120,000 catch basins.
Description: These are the jurisdictions covered by the four Road Maintenence District tree crews. It was derived from the Road Maintenance District boundary layer as the tree units cover the same areas as the road crews although there is only one tree unit per each of the 4 MDs, whereas there can be many road crew RDs per MD. To create the layer all of the RDs in each MD were merged into one multi-featured polygon. This layer is used in the Service Locator and The Works App.
Description: More information on County Road Maintenance is at http://dpw.lacounty.gov/general/servicelocator/and https://www.arcgis.com/apps/webappviewer/index.html?id=d3029426b33a487ba68048066b527973 .Principle attributes in this layer include:EQUIPCODE: corresponds with the asset identifier in the county maintenance database.STREET : is the street name.CITY : corresponds with the road maintenance yard who typically maintains that road asset. For example, ROAD DIVISION 526. The format must match ROAD DIVISION ### exactly in order for the segments to appear corretly in the monthly RMD inspection map PDFs.This product is for information purposes and should not be used for legal, engineering, or survey purposes.
