View In: Map Viewer

Name: Stormwater gravity mains

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Subtypes:

Standard: A typical gravity main.

Inverted Siphon: A gravity main that siphons stormwater to flow under an obstruction.

Other: All other types of gravity mains.

Attributes: Most of the feature classes in this storm drain geometric network share the same GIS table schema. Only the most critical attributes per operations of the Los Angeles County Flood Control District are listed below:

Attribute	Description
ASBDATE	The date the design plans were approved "as-built" or accepted as "final records".
CROSS_SECTION_SHAPE	The cross-sectional shape of the pipe or channel. Examples include round, square, trapezoidal, arch, etc.
DIAMETER_HEIGHT	The diameter of a round pipe or the height of an underground box or open channel.
DWGNO	Drain Plan Drawing Number per LACFCD Nomenclature
EQNUM	Asset No. assigned by the Department of Public Works' (in Maximo Database).
MAINTAINED_BY	Identifies, to the best of LAFCD's knowledge, the agency responsible for maintaining the structure.
MOD_DATE	Date the GIS features were last modified.
NAME	Name of the individual drainage infrastructure.
OWNER	Agency that owns the drainage infrastructure in question.
Q_DESIGN	The peak storm water runoff used for the design of the drainage infrastructure.
SOFT_BOTTOM	For open channels, indicates whether the channel invert is in its natural state (not lined).
SUBTYPE	Most feature classes in this drainage geometric nature contain multiple subtypes.
UPDATED_BY	The person who last updated the GIS feature.
WIDTH	Width of a channel in feet.
