Site Development Plan (SDP) - What It Is and When You Need One
What a Site Development Plan is, when municipalities require one, what it must include, and how Landlodz prepares SDPs for SA applications.
A Site Development Plan (SDP) is a scaled, dimensioned plan showing the details of a proposed land development - site layout, positioning of buildings and structures, property access, parking, engineering services, and landscaping - as required by a municipality's land use scheme.
When an SDP is required
Municipalities commonly require an SDP:
- As a condition attached to a rezoning approval
- Alongside certain consent use or departure applications
- For multi-unit residential, commercial or mixed-use developments
- Where a scheme specifically requires one before a building plan can be submitted
What goes into an SDP
- Site layout and building footprints
- Access points and internal circulation
- Parking layout and bay counts against the scheme's required ratio
- Engineering services (water, sewer, stormwater) at a level the municipality can assess
- Landscaping and any retained features
Cost and timeline
SDP cost and timeline depend on the complexity of the site and what it's being submitted alongside. See the pricing page rather than relying on a generic estimate.
FAQ
Who prepares an SDP - an architect or a town planner?+
It's typically prepared by a town planner or draughtsman working from the scheme's requirements, sometimes in coordination with an architect's building design.
Can I submit a building plan without an SDP?+
If your municipality's scheme or your rezoning conditions require one, no - the SDP usually has to be approved before or alongside the building plan.
