Greck was retained to obtain approvals with the TRCA and the City of Richmond Hill for the design of a residential townhome development located in an established floodplain area. A hydraulic analysis and flood study was completed to assess existing and proposed flood conditions.

After detailed analysis, including updating hydraulic flow rates and undertaking a new topographic survey to redefine cross-sections and culvert crossings, the flood line was reduced allowing development to proceed.

Deliverables included the preparation of a flood hazard assessment report with updated floodplain/constraint mapping in coordination with other stakeholders.
