TO: City Council
FROM: General Manager of Engineering Services
SUBJECT: Reconstruction of 4600 Block West 8th Avenue
RECOMMENDATION

an 8.5 m pavement and corner bulges at each end of the block.
B. THAT $75,000 be allocated from Streets Basic Capital
Unallocated Account No. 12/31/2802/999 - Local Street
Reconstruction.
COUNCIL POLICY
City Council approves changes to street width.
PURPOSE
To determine a design for the reconstruction of the 4600 Block of West
8th Avenue.
DISCUSSION
Recent sewer and water construction on the 4600 Block of West 8th Avenue
has damaged most of the existing pavement. Due to the amount of
pavement to be replaced and condition of the remaining portions, the
entire curb and pavement should be replaced. 8th Avenue is part of the
Off-Broadway bicycle route, which connects to UBC. The existing roadway
width is 7.9 m (26 ft.), which is below the typical single-family
residential standard of 8.5 m (28 ft.).
The reconstruction provides an opportunity to widen the road by 0.6 m (2
ft.) to the standard. Existing street trees would not be affected. An
8.5 m width would provide a little more room for bicycles meeting
oncoming cars.
Normally, reconstruction work does not involve property owners because
the pavement width is maintained. In this case, staff believe that a
slightly wider pavement will be beneficial, particularly for bicycles.
Therefore, property owners were consulted through a public opinion
survey. The options included in the survey (see attached example) were
as follows:
i) maintain the existing 7.9 m width
ii) widen to an 8.5 m width, with a 1.5 m bulge at each end.
The bulge was proposed to reduce the entrance widths to the block. (The
entrances would be 7.0 m, which would be 0.9 m (3 ft.) narrower than the
existing width.) This is intended as a calming measure, which would slow
traffic entering the block, but would not divert traffic to other
streets. The 35 property owners in the block were sent the survey and
27 (77%) were returned, which is a very high response rate. The results
were as follows:
Maintain the Widen to 8.5 m Either Neither
Existing width with bulges width width
1 23 1 2
Since there is strong support to proceed with an 8.5 m width with corner
bulges and the street needs to be repaired, it is recommended that
Council approve this reconstruction.
FINANCIAL IMPLICATIONS
The estimated cost of the work is $165,000. The majority of the funding
of $90,000 is available as part of the Sewer and Water construction.
However, additional funding of $75,000 is required to complete
reconstruction of the block. It is recommended Council approve these
funds which are available from the Streets Capital Account set aside for
local Streets reconstruction. Note that allocation of additional
funding would have been needed with or without the slight increase in
width.
