Description:



This data layer shows all utility poles in Newton. It has been used primarily for street light maintenance. This can lead to some confusion because not all poles have street lights attached to them. Poles that don’t have lights (usually telephone poles) have no values for the street light attributes such as [LAMPTYPE] and [LUMENSIZE]. To show only street lights use a selection based on lamp type not being “0”. The primary identifier for street lights and poles is the [RID] field. This corresponds to the numbers that appear on the poles. It is a concatenation of a pole number and one or two post numbers with slashes separating these components (eg. 123/5 or 112/4/5). Not all RID values are unique. This has caused some problems but we have set up workarounds in our processes to alert users to the multiple occurrences of pole numbers. Some other structures show up in this database for unknown reasons so there are RID values such as “TREE” and “POLICE BOX”



Some street lights along major streets are mounted on concrete poles. These poles did not have numbers originally because they were difficult to put numbers on. The original database listed them as “0/0” for the RID. The City of Newton created a numbering scheme for them based on a combination of the first 4 letters of the street name and the nearest address. For example the pole close to 1172 Walnut Street has an ID of “WALN/1172”. These numbers were affixed to a plastic band that was mounted to each pole.


Features and Attributes:

           

            The layer consists of points at the base location of each pole. Attributes came from the electric company. Some of the fields that are not used by the city were removed. Other attributes were added by the GIS Administrator in support of maintenance such as the Hansen database fields, DPW Administrative areas such as snow plowing routes, parcel IDs and address information. Addresses were automatically calculated to the closest record found, not always on the correct street.
