The Richmond Hill Infrastructure and Engineering Services Department's geotechnical study requirements, linked from the city's site alteration permit page. It describes the study as an objective sub-surface investigation of soil and bedrock, prepared and stamped by a professional engineer licensed in Ontario, with recommendations for earthworks, drainage, sewers, utilities and pavement. Its outline covers investigation and evaluation, impacts and mitigation, site-specific percolation tests for infiltration facilities, and slope stability studies, with resources including Division H.2.7 of the City Standards and Specifications Manual and TRCA's geotechnical submission requirements.
