Özet

Flood-prone settlements require planning approaches that can connect risk evidence with land-use decisions, property rights, and feasible policy instruments. This issue becomes more visible where private parcels are located in areas in which future development may need to be limited for public safety, climate adaptation, and nature-compatible land management. This contribution focuses on the Araklı district of Trabzon, Türkiye, where a severe flood occurred in 2019. It proposes a GIS-based planning workflow to discuss how flood-related spatial evidence could support policy decisions on risk-sensitive urban development and property-right arrangements. The proposed workflow would begin with the identification of flood-affected and flood-susceptible areas. Satellite images, including Sentinel-1 SAR data, topographic information, and existing GIS layers would be used to derive an initial flood footprint and support susceptibility analysis. These outputs would be treated as preliminary spatial evidence and would need to be checked through accuracy assessment, visual interpretation, local knowledge, and available reference information before any parcel-level interpretation. The main policy concern is how floodrelated constraints could be translated into fair and implementable planning decisions. Refined flood outputs would therefore be evaluated together with cadastral parcels, land-use data, planning layers, buildings, infrastructure, and ownership information. This spatial evaluation is intended to identify parcels where development restrictions may be required and to clarify whether these areas may need urgent intervention, long-term planning control, or a combined approach. Restricted flood-risk areas would also be considered as possible spaces for nature-based solutions, green infrastructure, and flood attenuation functions. This perspective would connect property-right reconfiguration with wider adaptation agendas, including sustainable urban planning and resilient land-use systems. Value-based land readjustment, transfer of development rights, land exchange, public acquisition, and compensation are discussed as possible policy tools. Particular attention is given to two options: transferring development rights while ownership remains in place, or transferring both ownership and development rights where public safety, environmental sensitivity, or future land-use decisions require stronger intervention. Receiving areas could be assessed through 3D urban modelling to estimate possible effects on density, building mass, infrastructure demand, and urban form. The proposal seeks to connect flood evidence with spatial restrictions, compensation options, and planned urban growth within a common framework. Although developed around the Araklı pilot area, the workflow may also support discussion on how flood-prone settlements can reduce risk in vulnerable areas while addressing property rights, development pressure, and sustainable land-use transitions.
