Strategic Site Selection & Land-Use Optimization

Strategic site selection and land-use optimization underpins responsible port and terminal development by shaping where and how infrastructure is established before design decisions are fixed. Early choices about location and spatial layout have a decisive influence on environmental outcomes, construction complexity, long-term operability, and community acceptance. As such, this practice places strong emphasis on upfront planning that carefully balances operational requirements with environmental and social constraints.

A core principle is to make best use of already disturbed or developed land, including existing ports, industrial sites, or modified coastlines, before considering development on undeveloped land. Where new sites are required, early investigation of coastal processes, seabed conditions, and ecosystem values is essential to avoid locations that demand extensive and/or ongoing dredging, reclamation, or artificial protection. Selecting sites with natural advantages, such as sheltered waters, suitable depths, and stable geomorphology, create opportunities to reduce physical intervention while improving resilience.

Equally important is optimizing land use within the selected site. Well-designed spatial planning enables compact development footprints, clear and logical phasing, and adaptability for future expansion, thereby limiting environmental disturbance over the project lifecycle. Designing layouts that work with natural processes, rather than attempting to constrain or override them, can significantly reduce ongoing maintenance requirements and enhance long-term performance

Strategic site selection and land-use optimization is a foundational practice in sustainable port and terminal development. Its purpose is to minimize environmental disturbance, reduce long-term costs, and improve functional efficiency by carefully selecting development sites and configuring layouts that respond to existing natural and land-use conditions rather than relying on extensive engineering intervention (PIANC, 2019). The practice directly addresses key issues associated with port development, including habitat loss, extensive dredging and reclamation, land-use conflicts, and inefficient use of coastal and terrestrial space.

The practice prioritizes the use of brownfield or previously disturbed sites wherever feasible, including underutilised port land, former industrial areas, or redeveloped waterfronts. It is recommended that the potential redevelopment or expansion of existing port areas be fully explored before progressing to greenfield options, as part of a sustainable planning sequence. PIANC provides separate masterplanning guidance for existing ports (PIANC, 2014) and greenfield sites (PIANC, 2019). Where greenfield sites are unavoidable, early-stage screening is used to identify locations with favorable natural characteristics such as deep-water access, natural shelter, stable seabed conditions, and low ecological sensitivity (PIANC, 2019). Early ecosystem assessments, covering marine, coastal and terrestrial environments, allows high-risk sites to be avoided before design decisions are locked in, rather than relying on later mitigation.

Globally, strategic site selection and land-use optimization has been applied in new port developments and expansions. Examples include ports that have selected sheltered bays (Salaverry Port, Peru), a new harbor in Nigg Bay next to the existing port (Aberdeen South Harbour, UK), or brownfield expansion zones (Sabine Pass LNG Terminal, USA). The PIANC “Working with Nature” philosophy underpins many of these projects by integrating ecosystem understanding and stakeholder engagement into early planning stages (PIANC, 2019). These principles are further outlines in World Bank (2025).

In DMCs, the relevance of this practice is particularly strong due to dense coastal populations, sensitive mangrove and reef systems, and high exposure to sedimentation and coastal dynamics. Several recent port and terminal developments have incorporated early site screening and land-use optimization to avoid extensive mangrove clearance, reduce reclamation footprints, and maintain sediment pathways. In deltaic environments, site selection that avoids extensive channel deepening is considered critical to long-term operability.

Successful implementation relies on several enabling factors. From a policy perspective, clear planning frameworks that encourage brownfield redevelopment and require early environmental assessment are essential. Technically, access to reliable bathymetric, geotechnical, metocean, and ecological data enables robust multi-criteria site screening. Sustainable procurement and delivery models that allow flexibility and supports long-term value, environmental and social outcomes, rather than prescriptive early design, support optimization. Finally, strong partnerships between port authorities, planners, regulators, and local communities are critical to identifying viable sites, managing trade-offs, and achieving stakeholder acceptance.
