Description: Data Type: Polyline data
Subtypes:
Stream: A natural drainage course devoid of human interference.
Watercourse: A channelized natural drainage.
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. |
