CITY OF PORT COQUITLAM Page 1 of 5

The purpose of this report is to survey the existing street lighting in
the Port Coquitlam "Downtown" Area and make recommendations for the
installation of ornamental street lighting.

The "Downtown" Area to de studied is bounded by Kingaway ~ Mary Hill Road -«
Wilson - Bury - Coquitlam River, and contains the following streats; Elgin,
KeAllister, whyte, Marpole, Donald and Maple Streets.

(Refer to Drawing in the Appendix.)

EXISTING STREET LIGHTING

The existing street lighting in the Area is generally inadequate and consists
of the following:

(1) Crnamental street lighting is presently installed on Shaughnessy Street.
The installation gives a minimum lighting level of .7 foot candles for
a main commercial street. The recommended lighting level is 2.0 foot
candies. (A sample of this lighting level can he viewed at the commercial
area on Austin Avenue, Coquitlam.) The equipment is 14 years old and
maintenance is a problem due to overloaded circuits, absence of fusing
at each pole, and deterioration of the wiring system.

Ornamental street lighting on Bury Street. This installation is new

and equiprent is as required in Port Coquitlam street lighting standard
specifications.

Masteara lighting mounted on B.C. Hydro poles on Wilson, Mary Hill Road,
Kingsway, Elgin (part), McAllister, Whyte, and Marpole. Mast-ara
lighting consists of a mercury-vapour luminaire on a steel arm, mounted
on the Hydro wood pole. This lighting is uneven and patchy and generally
unattractive.

No street lighting exists cn Donald, Maple, and a portion of Elgin Street.

TING B.C. HYDRO AND B.C. TELEPHONE SYSTEMS

overhead wiring systems of B.C. Hydro and B.C, Telephone exist on all of
streets of the Area with the exception of Shaughnessy, Donald, Maple, and
a@ portion of Elgin Avenue. :

Tnese wiring systems, in addition to heing very unattractive, would create
conflicts to the iastallation of ornamental street lightizg usaits.

EXISPING B.C, EYDRO AND B.C. TELEPHONE SYSTEMS cont'd

Serious consideration should be given to the relocation of these systens
in lanes or underground before installation of ornamental street lighting.
The high voltage Hydro lines on towers and poles on Bury and Wilson could not

be econgmically rejor.ed. The Hydro and Telephone lines on Hary Hill Road
and Kingsway would alse be difficult to relocate economically,

However, the overhead lines on Marpole, Whyte, McAllister and Elgin could
probably be relocated in lanes and taus permit the installation of
ornamental street lighting on these streets to greatly improve appearance
and saféty.

ORNAMENTAL STREET LIGHTING EQUIPHENT -

An ornamental street lighting installation requires a light source or lamp,

support the luminaire. . .

(1) Lames

Strect lighting lamps in present usage are: incand %, fluorescent,
low-pressure sodium, mercury vapour, and high-pressure sodium.

Incandescent, fluorescent, and low pressure sodium are rarely used for
new ornamental lighting installations because their capital costs,
operating costs, .and maintenance costs are approximately double that of
equal mercury-vapour and nigh-pressure sodivm installations.

Mercury-vapour installations are most widely used because of lower costs,
good colour rendition with new deluxe white lamps, and long life.

High-pressure sodium lamps are beconing more commonly used because of
their greater efficiency and thus energy consumption of approxinately
50% of mercury vapour lamps of equal light output. With clisbing .
energy costs and emphasis on energy saving, this is an important factor.

. However, due to their high intensity point source of light, glare can
be a problem, unless special luminaires are used or luminaires are
mounted at a higher level than mercury vavour luminaires. Also, the
colour, of high pressure sodium is a oright yellow-orange and the public
is just beginning to accept their usage. Their most corimon application
to date has been on bridges, interchanges, and major arterial roadae.
