Name: Valves

Display Field: LID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Originally created by Claunch & Miller, Inc. (part of HDR Engineering as of 2008) in 2002, this file has been maintained in-house since then. Updates are provided through a combination of as-builts, field verifications, and word of mouth from employees who have worked on a particular feature.Field breakdown: POINT_ID [Valve ID] contains the unique identifier for each valve, with the first digit references the fire district in which the valve is found. ASSETID [Asset ID] is the randomly assigned, unique identifier used by VUEWorks (Public Works' work order system)*. LID [Lid Condition]uses the ValveLid domain to rate the condition of the valve’s lid (note that this field has not been updated since the valves were originally entered). PHYS_LOCA [Physical Location]uses the ValveLocation domain to describe where the feature is located (e.g., street surface). TYPE [Type]uses the ValveType domain to denote the type of valve (e.g., gate valve). OPEN_DIREC [Open Direction] designates the direction (left or right) the valve must be turned to open it. DIAMETER [Diameter (in)]uses theWLineSize1 domain as a dropdown to record the diameter (in inches) of the valves. POSITIONTYPE [Position Type] categorizes the valves by their relation to other water infrastructure. The GPS_DATE [GPS Date] and GPS_TIME [GPS Time]fields contain information about when the feature was originally shot into the system. The NORTHING [Northing (Y)], EASTING [Easting (X)] Z [Elevation (Z)] fields contain coordinate data. DEPTH_HEIGHTis the below or above Z, the surface elevation. The following fields were populated by Data Transfer Solutions in 2017: IMAGE [Image]contains the file name of a picture of the feature; STREET [Street]contains the name of the street on which the feature is located; CONDITION [Condition] and CONDITIONINDEX [Condition Index] are condition ratings; and the INSTALLYEAR [Installation Year] and CONMMENTS [Comments] fields should be self-explanatory. To derive the actual elevation of a feature = Z + DEPTH_HEIGHTAll Z values are in feet. All Elevation data is Surface Elevation.Due to VUEWorks, care must be taken when deleting features. The IDs cannot be reused and must be retired after a deletion. The retired IDs for this feature class are: 1681, 1700, 1735, 2240, 2241, 3781, 5292, and 6871. (The retired Valve IDs are: 10640, 10812, 10863, 10864, 11229, 50502, 50503, and unknown.)* The reason for two different IDs is that VUEWorks uses randomly assigned IDs; it cannot handle IDs that have meaning.
