The Consultant has presented a revised recommendation at the Drainage and Flooding Committee meeting scheduled for August 19, 2009.

The Agreement will be presented to City Council for consideration at the September 14, 2009 meeting. A meeting was held on September 2, 2009 with Mike Talbot of HCFCD to discuss the Brookglen area. Apparent problems with the modeling in the Brookglen area were discussed along with options and solutions. Talbot was willing to work with our more detailed engineering information on the B1l2-02 plan as long as the information supports an abatement of losses. The next buyout application is due by end of September. They need us to confirm their candidate list taking into account the effects of B112-02 improvements and avoiding the checkerboard effects to the community as much as possible.
