What SSD And SSI Mean
State Significant Development records usually relate to major development proposals assessed through the NSW planning system. State Significant Infrastructure records usually relate to large infrastructure projects such as transport, energy, water, or public works.
These projects are different from ordinary local development applications. They are usually larger, more complex, or considered significant because of their type, scale, location, economic role, environmental impact, or public infrastructure function. That makes them useful records for people trying to understand future change around a place.
State Significant Development and State Significant Infrastructure records can involve many stages. A project may start with requirements for assessment material, move through exhibition and submissions, receive a recommendation, be determined, and then later be modified. A project appearing on the map does not always mean construction is happening now or that final approval has been granted.
How To Read A Project Record
Useful fields can include the project number, project name, type, status, location, proponent, assessment stage, determination date, and official Planning Portal link. A modification record may relate to an earlier base project rather than a separate location.
The project number is often the best anchor. SSD, SSI, and modification references can look similar but mean different things. A modification usually changes, extends, or refines a base project rather than creating a completely separate project. Komand groups modifications with their base application where the numbering makes that relationship clear.
Status is also important. A project in early assessment should be read differently from a determined project. A project with a determination date has reached a formal decision point, while a project in exhibition or response to submissions may still change. When timing matters, open the official record and check the current stage, document dates, and any recent notices.
Why Map Locations Need Care
Planning project locations can be approximate, especially for large sites, corridors, staged projects, or records with incomplete address data. Komand may group related project modifications and show location review signals where source coordinates and address-based coordinates differ.
A single map point cannot always represent the full project. A road, rail, transmission, water, mining, renewable energy, or precinct project can cover a large area. In those cases, the marker may be a reference point, a project office-style point, a centroid, or a point derived from available address text. It should lead the user to the project, not replace the official maps and documents.
Some source records include coordinates. Some include address text. Some include both. Komand keeps those values separate where possible and can compare them. If the difference is large, the record may be flagged for review. A flag is not a judgement that the project is wrong; it is a signal that the map location deserves checking before being relied on.
Before Relying On A Project
Check the official NSW Planning Portal record, supporting documents, project status, date history, and map context. A nearby project does not automatically mean a property is affected, approved for change, or exposed to a particular impact.
Read the project description and documents before drawing conclusions. A project name may be broad, while the actual works may be limited to a particular site, stage, route, or approval boundary. Submissions and assessment reports may discuss impacts that are not obvious from the project title alone.
Distance from a marker is only one part of the picture. A nearby property may be unaffected, while a more distant property may be relevant because of access, view corridors, noise paths, infrastructure connections, catchments, or project staging. Use the map to find records, then use the official documents to understand the actual relationship.
Using The State Significant Projects Map
The map is designed for scanning and filtering. Start with the area or project number you care about, then narrow by project type, status, and date range. If there are many records in one place, check whether they are modifications of the same base project rather than unrelated projects.
The map can also help identify patterns. A cluster of projects may show infrastructure investment, industrial activity, energy development, education or health investment, or changing land use pressure. Those patterns can be useful for further checking, but they should be treated as prompts rather than proof of a particular outcome.
