‘60 that the rare storm will not produce a great deal of damage.
The report suggests that lots be graded to-be above the level
of the one in 25 year flood and that building floor elevations
be set to be above the level of a one in 100 year flood.

4. The required channel storage capacity could be
accommcdated either by increasing the sizes of the existing
ditches along Broadway and Coast Meridian or by replacing these
with one new ditch. The advantage of being able to eliminate
‘the ditches on Broadway and Coast Meridian are that the road can
then be widened without acquisition of additional right-of-way,
and that individual properties will not require bridges for access
to the streets. The appearance of our major access points from
the Mary Hill By-Pass with an open ditch alongside could also be
considered. By diverting the flows to a new channel between
Broadway and Coast Meridian, the City has the opportunity to
minimize the effects of this channel on the surrounding properties
and yet to provide a low cost solution to the storage problem.

5. I would draw your attention to the recommendations
on pages 14 - 16 of the report, and in particular recommendgation
number 5 which recommends priorities for construction. One of
the requirements of the alternative drainage system as proposed
inthhe report is that an additional culvert wiil have to be
installed across Broadway Street in conjunction with the two
culverts already being installed as part of the Mary Hill By-Pass
construction. As this contract is now underway, it would be
weneficiaul to us if Council would adopt these recommendations
and authorize us to have the Ministry of Highways install an
additional culvert. Provision for funds for this additional
culvert and also for some work on the Uarhour Strect pump station
have been included in the Provisional Pudqet for 1980,
