1. Introduction
This is the forth edition of the Street Lighting Design Guide (formally entitled
“Guidelines for Siting and Design of Illuminated Street Furniture in the Public
Highway”.
The document is the 2nd in a suite of documents consisting of :
ƒ
ƒ
ƒ
ƒ
The Street Lighting Policy Document (4th revision)
PFI Standard Design Specifications (including the Street Lighting Design Guide
and the Street Lighting Material and Works Specification)
Standard Detail Drawings (Series L)
Manual for Streets.
It is intended that this document be read in conjunction with these other publications.
Installing any type of street furniture on the public highway can cause problems;
whether they are obstructions by tree, overhead lines, vehicle access or concerns from
local residents.
This guide has been produced in order to overcome some of these general issues where
they relate to street lighting, illuminated bollards or signs etc. However, it should not be
viewed as a “be-all and end-all” guide as each site will have it’s own unique set of
circumstances which will dictate the final scheme design.
2. Design Guidance.
General guidance on whether lighting should, or should not, be installed can be found in
the Street Lighting Policy Document. Tables 2.1 – 2.3, below, indicate the lighting levels
to be achieved in Zones E2-4.

Obstructions to Avoid.
•
•
•
•
•
•
Trees
Bushes/hedges
Overhead lines (electrical)
Overhead lines (other)
Vehicular accesses / gateways
Bedroom windows
Of course this list isn’t intended to be exhaustive so there may be others that are not
mentioned. It should, however, be clearly noted that all columns must be located in the
Highway unless a Wayleave or Deed of Grant has been signed by the landowner.
a. Trees.
Trees, both large and small are a constant problem when it comes to installing
lighting columns. The following observations must be adhered to by scheme
designers and maintenance operatives when considering column locations:
1. The scheme shall be designed so that columns are sited mid way between
trees even if the design criteria is exceeded.
2. Where there an alternative location, away from the tree, then utilise this
location and reconfigure the design accordingly.
3. It may be possible to locate a column underneath the tree canopy but it
must be at least 1m clear above the lantern and the designer must be sure
that this space will not be encroached upon at a later date.
4. When locating columns amongst trees lanterns must be clearly visible
when standing at the mid point between columns (See Figure 1)
Figure 1 – Tree Trimming Detail
Standard Development Specification - Street Lighting Design Guide 08/07/2010
Environment Department
Street Lighting Section
Figure 2 – Tree Trimming Flow Chart
b. Bushes/Hedges
Whilst bushes most likely won’t block the lantern they will prevent future
maintenance by blocking the access door. Trimming needs to be carried out on a
regular basis so it is best to move the column away from existing locations where
possible.
c.
Overhead Lines.
Scottish and Southern Energy plc (S&SE) publish guidelines for the placing of
columns near LV or HV overhead lines but, in summary, these are:
0.5 times the height of the column for low voltage (insulated)
1.5 times the height of the column for low voltage (uninsulated)
2.0 times the height of the column for high voltage – wood poles}
2.5 times the height of the column for high voltage – steel towers}
Columns must not be positioned any closer than these limits. However, where
height may allow for closer positioning the designer must consult with S&SE and
obtain written consent as regards location.
Warning signs should be fitted to columns located underneath any high voltage
cables as per HCC Standard Detail HCC9/L/165.
d.
Overhead Lines (other)
Wherever possible columns should be positioned to avoid conflict with overhead
lines such as BT cables etc. Where such conflict is unavoidable there must be
Standard Development Specification - Street Lighting Design Guide 08/07/2010
Environment Department
Street Lighting Section
sufficient clearance to enable an operative to gain access to the lantern via a
cherry picker or hoist.
e.
Vehicular accesses / gateways
Columns must never be positioned in a manner that blocks access, gateways or
any other form of access to property. Normally (but not always) locating
columns on property party lines will avoid this. However, in any case, columns
must not obstruct site lines for vehicles entering onto the highway.
f.
Bedroom windows
Light intrusion into properties should be avoided as much as possible.
Consideration must be given to possible problems in all cases and, if necessary,
the affected residents consulted. Where necessary shielding requirements should
be identified at the site fit stage and fitted as a matter or course. However shields
cannot be installed on columns in excess of 6m mounting height. Where
columns in excess of this height are proposed then flat glass lanterns may be
required and angled away from the affected property. Manufacturers lantern
based external front and rear baffles may also be used.
g.
Footpaths (narrow & wide)
Where columns are being located on footpaths the choice of column position will
depend on the width of the footpath and any verge area available. In most cases
there will be 3 possible alternatives as shown below:
Eg.1 Column mounted in verge with minimum setback (see Table 2 for details)
Column locations
Eg.2. Column mounted at rear of verge

Fold Down (Raising and Lowering or Mid-hinged) Columns
Fold down columns are designed for installation in locations where the lantern and
control gear etc cannot be reached by means of a vehicle mounted lift, a ladder, mobile
extending working platform (MEWP) or other recognised safe means. There are,
however, considerations that must be taken into account to ensure their effective use.
Because of their design care must be taken to ensure there is sufficient clearance to
enable the column to be lowered, and raised again, without obstruction. When in its’
lowed position the column shaft should not obstruct pedestrians (i.e. it should not have
to lie across a footpath or cycleway). There should be sufficient room for an operative to
work safely away from buildings, steep slopes, traffic routes or bodies of water.
Such columns should not be used as a tool of convenience and should only be
employed where there is no chance of vehicular access and all other reasonable
means of safe access have been eliminated.
5. Column Colours
The required colours for street lighting columns within the County are based on BS
4800 and generally are as follows:•
•
12 B 21 “Lovat Green” (Valspar colour name)
00 E 53 “Black” (Valspar colour name)
6. Checks on Completion
Visual Checklist
The following are visual and electrical inspection checklists which must be completed
for all new sites. This is the same list as used by County Council inspectors and, also, the
Independent Certifier employed under the Street Lighting Private Finance Initiative.
