This project began with the analysis of the existing storm and sanitary sewer capacities within a 2 ha. catchment around the proposed development. The sewers were assessed in both the context of the existing land-use with the proposed development, as well as with the catchment developed to the ultimate O.C.P. density. H.Y. Engineering provided the City of Richmond with recommendations for upgrades to the existing storm system for this proposed development and future developments within the catchment. Once the recommendations were adopted by the City and the requirements for the development established, H.Y. Engineering provided off-site and on-site design services for the project. The on-site designs involved turning analyses and included the service locations and connections, road grading and drainage details, turning analyses, curb and driveway details. Off-site designs included roadworks drawings illustrating the upgrades required along Hazelbridge Way and Leslie Road with streetlights and street trees, and designs for storm and sanitary sewer upgrades with connections.
