Thoughts about the relationships between transport and the urban area it serves

UPDATE Richmond Dykes

with one comment

There is a short story in the Richmond Review paper edition that is not on their web site

Since it relates directly to a topic recently discussed here I am going to copy type the relevant paragraphs

Middle Arm Dyke to rise half a metre

The Middle Arm of the Fraser will get millions of dollars in additional flood protection now that the green light has been given to a series of major dyke infrastructure upgrades in the city.

$2.4 million will be spent on bolstering more than 750 metres of dyke between Cambie Road and Hollybridge Way. Plans call for the dyke top be raised about half a metre, concrete floodwall retaining structures will be added, and rip-rap armouring will reinforce the river face of the dyke.

Some $4.8 million in funding – from the city, province and Ottawa – will be spent on upgrades to the No 4 Road drainage pump station.

This is a small sum for a small raise to a small percentage of the dyke. The rip rap is needed to reduce the impact of wash from passing vessels. The pump station is not on Middle Arm and is some distance from the area of dyke raising, so is really a separate project. Pumps get rid of water from behind the dyke.
