Services: Detailed Subdivision Design Layouts

64th Avenue 14 Lot Subdivision in Cloverdale

123674A_64Ave

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.

2 Lot Subdivision on the Panorama Ridge Hillside

113469_56th2Lot

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.

20 Lot Subdivision in South Newton

103112_20Lot

H.Y. Engineering Ltd. was involved with this project from initiation to completion including planning services to coordinate the rezoning and subdivision of the property with the City, and preliminary design of the subdivision layout and servicing concepts and alternatives. On-site and off-site design services included lot grading design, stormwater control plans, site servicing, roadworks with bus bay, and complex retaining walls. Erosion and Sediment Control (ESC) design, ESC monitoring, and construction inspection services were also provided for this project.

Cedar Creek Townhomes

This large multi-phased development, situated on Burke Mountain in Coquitlam, presented unique grading and stormwater retention and infiltration challenges due to the steep slope of the mountain. H.Y. Engineering coordinated with the City of Coquitlam Planning and Development Services Departments to obtain a Development Permit for the project, which included the preparation of the site servicing concept. H.Y. Engineering also provided engineering services for detailed design of the servicing and roadworks required for this project, as well as Erosion and Sediment Control (ESC) design and monitoring.

9 Lot Subdivision in

103187_9Lot

This subdivision included the creation of 9 single family residential lots.  The existing house on the property was retained on one of the new lots and the overall subdivision concept has maintained the half acre (gross) lot size in the neighborhood. In addition, our subdivision design also includes a concept that will interface with future development on the north side of 27th Avenue.

The site servicing included significant road upgrades as well as the construction of a new cul-de-sac bulb. The ultimate site grading was addressed through minimal retaining walls in order to address undeveloped neighboring properties. In addition, the development also required full storm sewer, sanitary sewer, and water main upgrades in order to service the current and future development. Tree preservation was a concern in this area and a significant number of trees were retained with covenants and unique building envelope designs.

The subject site is adjacent to the Sunnyside Acres Urban Forest Park (located on the east side of 144th Street) and also includes a greenbelt area located at the rear of the proposed lots (dedicated to the City as parkland). This greenbelt is in addition to the existing greenbelt that is running east to west and serves as a connection to the Sunnyside Areas Park for wildlife and pedestrian traffic.

This project required close interaction with the neighboring property owners in order to develop a concept that is consistent with the immediate and surrounding areas as well as ensuring proper interface with existing and future development.
