Published by City of Richmond Hill under Site Alteration Permits
The City of Richmond Hill's requirements for a geotechnical study, an objective sub-surface investigation by a professional engineer licensed in Ontario that analyses soil and bedrock to determine structural stability and a site's capacity for the proposed development, roads, and services. It calls for site-specific percolation testing to size any infiltration facility, and adds a slope-stability study — meeting the Toronto and Region Conservation Authority's own geotechnical submission requirements — where the work involves or sits near a slope or watercourse. City Standards and Specifications Manual Division H.2.7 sets the fuller technical detail.
