That Council approve the expenditure of $11,000 for dredging of the Cedaa Ditch between
the Cedar Storm Pump Station and the culverts at Victoria Drive.

That $11,000 be allocated from the Future Capital Works Reserve for this purpose.

The Public Works Committee considered the attached memorandum dated April 27, 1992
regarding a request for Mr. Barnes of 917 Richmond Place to correct the flooding being
experienced at the location.

For the past several years there have been flooding problems with the storm sewer backing up
through the catch basin in the cul-de-sac at Richmond Place. The Richmond Place cul-de-sac is
the lowest point in the Cedar Pump Station catchment area. |

Dayton & Knight engineering consultants have suggested the following options:

1) Dredge Cedar Ditch - $11,000

2) Install a small pump station at the cul-de-sac - $50,000
3) Upgrade Cedar Ditch Pump Station - $875,000

4) Enclose a portion of Hyde Creek - $750,000

It is recommended that the Cedar Ditch be excavated to the original cross section shown in the
engineering construction drawings in order to increase the hydraulic capacity of the Cedar Ditch
and there by help alleviate the drainage probsern at Richmond Place.
