This 25 unit townhouse development was situated on a steep embankment with forested ravines on each side of the development which presented unique grading and storm water control challenges. The design solution involved heavy storm event flows being diverted to a large trunk main sewer. Off-site design included multiple road alignment options.

H.Y. Engineering has been involved with this project from feasibility to completion. The H.Y.E. Planning Department provided our Client with a feasibility study and preliminary cost analysis for the property. Planning services included liaison with the City and neighbouring property owners/developers to establish maximum development potential and cost savings opportunities beneficial to all parties.

Once the subdivision was approved, H.Y. Engineering provided subdivision layout and off-site design, project management services, construction services, Erosion and Sediment Control (ESC) design and monitoring, and inspection services. The designs illustrated a storm water management plan, lot grading and infiltration gallery details, sanitary main extension and connections, watermain extension and connections, and significant roadworks design including the upgrades of the existing 64th Avenue arterial road, the extension and completion of the 64A Avenue collector road, and a lane to be constructed behind the development all with required sidewalks, curbs, gutters, and streetlighting.

H.Y. Engineering provided planning, engineering, and survey services for this private two lot subdivision on 56th Avenue in Surrey. The property is situated atop a steep slope, with properties below, requiring additional efforts for Erosion and Sediment Control (ESC) and storm water management design which involved significant coordination with the City of Surrey Planning Departments (Subdivision and Building Divisions), the City’s Engineering Department, and with various sub-consultants (geotechnical, landscape, building design, directional drilling etc.) to address the engineering concerns of the site. H.Y. Engineering prepared off-site designs illustrating lot grading, and connections to the sanitary, storm, and water services as well as provided the design for the Erosion and Sediment Control (ESC) system implemented for the construction of the new home on the property.

Sensha-Ya Hand Car Wash

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.
