Fire Hydrants

 

Description:

 

Points represent fire hydrants. While a part of the water distribution system, the hydrants are not connected to that network.

 

Creation, History and Update Process:

 

These points were obtained from a query of the water system nodes. The nodes needed to be removed to simplify the water network to meet the networking software’s requirements at the time. Also the hydrant laterals were eliminated from the system. Hydrants were made into a separate layer for easier display and to allow permissions to users that do not need to access to the more secure water system layers. See the discussion for the Water System for more details.

 

Hydrant attributes originally included the same hydrant number that appeared in the Engineering Dept. version of the atlas.  However these numbers were unique only within an atlas sheet.  Therefore, the hydrants were re-numbered in 2011 with a unique sequential number based on the atlas numbers. The first digit indicates the atlas sheet and in where possible the other digits were preserved from the original numbering system. After cleaning up the data, this resulted in a numbering scheme that is both sequential and unique. The number from the atlas has been retained in the [orig_num] field.

 

Features and Attributes:

 

This data layer represents fire hydrants as points.  Fire engine districts were added by request from the Fire Department in Febraury, 2011.
