Geometry Type: esriGeometryPoint

Description: Subtypes:Cistern: A watertight, enclosed basin used to catch storm water runoff and precipitation. It is used for pollution control, volume reduction, and peak flow reduction of storm water runoff.Debris Basin: A basin that captures sediment, gravel, boulders, and vegetative debris washed out of canyons during storms. Debris is caught, allowing water to flow downstream through the storm drain system.Detention/Retarding Basin: A basin used to store storm water runoff for a limited period of time by allowing large inflows with limited outflows. These basins are also referred to as dry ponds, holding ponds, or dry detention basins.Reservoir: A basin designed to accommodate the storage of water for supply purposes, typically confined by a dam.Retention Basin: A basin including a permanent pool of water. They typically appear as artificial lakes with perimeter vegetation. They are also referred to as wet ponds, wet detention basins, or lake fails.Temporary Dam: A basin designed to be used for a limited period of time.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:AttributeDescriptionASBDATEThe date the design plans were approved "as-built" or accepted as "final records".CROSS_SECTION_SHAPEThe cross-sectional shape of the pipe or channel. Examples include round, square, trapezoidal, arch, etc.DIAMETER_HEIGHTThe diameter of a round pipe or the height of an underground box or open channel.DWGNODrain Plan Drawing Number per LACFCD NomenclatureEQNUMAsset No. assigned by the Department of Public Works' (in Maximo Database).MAINTAINED_BYIdentifies, to the best of LAFCD's knowledge, the agency responsible for maintaining the structure.MOD_DATEDate the GIS features were last modified.NAMEName of the individual drainage infrastructure.OWNERAgency that owns the drainage infrastructure in question.Q_DESIGNThe peak storm water runoff used for the design of the drainage infrastructure.SOFT_BOTTOMFor open channels, indicates whether the channel invert is in its natural state (not lined).SUBTYPEMost feature classes in this drainage geometric nature contain multiple subtypes.UPDATED_BYThe person who last updated the GIS feature.WIDTHWidth of a channel in feet.
