Erin Ridge North
St. Albert, AB
For this 92.2 ha development in northeast St. Albert, ISL prepared an Area Structure Plan (ASP) that incorporated a major arterial roadway, an existing church with its future campus, an extensive trail network and a school/park site in the heart of the neighbourhood.
The development included a 21.5 ha commercial development corridor as well as 17.19 ha of single family residential land, for which ISL provided land use planning, land development, stormwater management, landscape design, environmental management and construction management.
To install a seven- to eight-metre deep sanitary trunk sewer below water table in silty clay, a portion of the deep sanitary trunk was designed in a proposed walkway due to trench disturbance rather than along local roads, allowing houses to be constructed without piles and eliminating potential road settlement.
Future Stage Planning
Preliminary grading design for the future 62 hectares of land and 1500 metre of offsite St. Albert Trail widening ensured that material from Stage 1 and 2 construction was placed accurately while meeting the intent of an overall earthworks balance for the entire development.
