Fish passage planning and design requirements for a project are determined by the type and scale of project (e.g. design of new highway section, impact mitigation for urban waterway structure) and the stage of the project activities (e.g. preliminary concepts, implementation, monitoring and evaluation).
Aquatic fauna connectivity / fish passage design projects may relate to a range of spatial scales (e.g. catchment scale prioritisation, road corridor scale assessment, site scale fishway design). Undertaking either a broad scale (e.g. catchment) or fine scale (e.g. site) assessment / design project will determine the level of detail and the focus of the work.
Planning and design activities for these projects are best undertaken in a number of phases, leading from concept design through to detailed design and implementation. Doing this work in phases is beneficial as it provides the best opportunity to achieve the following benefits for the project:
provides expert input to meet multipurpose design requirements at the start of the project
allows progressive development of concepts, assessment, approvals and stakeholder input
minimises site assessment and detailed design effort in early project stages
reduces unnecessary financial commitment to projects that may not proceed
The scope of work for the project and the associated planning and design activities to be undertaken by JCU Engineering are determined in consultation with the client. Depending on the type and scale of the project and the stage of the project activities, this could for example include the following:
Aquatic connectivity impact assessment – Catchment / reach scale
Fish passage planning and design – Road corridor scale
Fish passage planning and design – Site scale
