Environmental Studies are characterizations of natural heritage features, functions and objective assessments of the direct and indirect impacts from proposed development. ABOUD & ASSOCIATES’ team of arborists, ecologists, and wildlife experts are trained and experienced to evaluate and document natural heritage features in accordance with established protocols.

With study sites ranging in size from several hundred hectares to less than one hectare in urban and rural settings, our team uses a reliable approach to create a comprehensive and defendable study. Typically this involves policy/legislation review, and preliminary consultation with the reviewing agency to determine the terms of reference. This guides the biophysical inventory to describe the condition and function of natural systems, and evaluates the ecological impacts of a proposed development using state of the art GIS/GPS technology. Where impacts are unavoidable, mitigation measures to minimize impacts are proposed along with monitoring programs to ensure long-term success.

Arkell Springs Dam Rehabilitation Scoped Environmental Assessment

City of Guelph, Guelph, 2010-present

 

Aboud & Associates prepared the aquatic and terrestrial biological component of a scoped environmental assessment for the rehabilitation of Arkell Springs Dam in collaboration with Gamsby and Mannerow for the City of Guelph. Natural heritage elements studied using existing data from public sources include: fisheries species assessment, classification of habitat and thermal regime (i.e. warm water, cool water, coldwater), identification of known spawning habitat, identification of known Species at Risk (SAR), and general classification of terrestrial habitat.

This information was evaluated to provide a general description of the habitat and features at the site. It was also applied to the Ministry of Transportation Environmental Guide for Fish and Fish Habitat which was used to assess the sensitivity of the habitat at the site and the potential risks associated with the proposed works.

Recommended mitigation techniques were also developed to address the negative effects of the proposed construction on the aquatic and terrestrial features and species located at the site to prevent the Harmful Alteration Destruction (HADD) of fish and fish habitat.
