Parcel screening and land due diligence

Is this parcel buildable?

Parcel due diligence with GIS puts everything known about a piece of land on one map before you buy, finance or build: zoning, flood zones, slope, protected areas, utilities and the market around it. We screen one parcel or thousands the same way and score each one, so your team spends its time on the parcels that pass.

The question

A parcel can look right on a listing and still fail on one layer: a wetland in the middle, zoning that caps the density, a flood zone along one side or slopes too steep to build on. Those facts sit in different places, from planning maps to flood maps and the land register, and checking them by hand, parcel by parcel, is slow.

Screening brings the layers together for every parcel at once and scores them on the rules you set. It also estimates the buildable area: what is left once setbacks, steep slopes, flood zones and protected land are taken out.

From inputs to result.

Inputs

Parcels

We start from the parcel layer, from the public cadastre or your own list, and attach what is known about each parcel: area, zoning and permitted density, ownership records where they are public, and a link to the property's assessment page.

Analysis

Constraints

Each parcel is overlaid with the constraint layers: flood zones, wetlands and protected areas, slope from an elevation model, utilities, and services such as nearby schools. The overlay measures how much of each parcel every constraint covers, not only whether it touches it.

Result

Score

Every parcel gets a score from the criteria you weight, plus its estimated buildable area. The scores go into a table and a web map where the team filters, compares and opens the parcels that pass.

What you receive.

01

Parcel table

One row per parcel, with every attribute, the share each constraint covers and the score.

02

Buildable-area estimate

The net area left for building, parcel by parcel.

03

Screening web map

Parcels coloured by score, with filters and a pop-up for each one.

04

Constraint layers

Flood, zoning, slope and protection layers, cleaned for your GIS.

05

Repeatable workflow

The same screening for new parcels or new data.

Limits

A screening estimate is not a topographic survey, a title check or a planning certificate; it shows which parcels deserve one.

Questions about this analysis.

01What does parcel due diligence with GIS include?

It checks each parcel against the layers that decide whether it can be built on: zoning and density, flood zones, wetlands and protected areas, slope and nearby services. Each parcel gets a score and an estimated buildable area, in a table and on a web map.

02Can you screen thousands of parcels at once?

Yes. The screening is built as a workflow, so the parcels of a whole county go through the same steps as a shortlist of ten. A larger area means more data, not a different method.

03Can you work from our own parcel list?

Yes. Send a list, a CAD drawing or a spreadsheet of addresses, and we match it to the parcel layer. Where the cadastre is missing or out of date, we tell you which parcels could not be matched.

04How exact is the buildable area?

Close enough to compare parcels, not to sign on. We subtract the land that cannot carry a building, using your setback rules and the slope, flood and protection layers, and report what is left. The surveyor and the planning authority have the final word.

05How do we see the results?

In a web map: parcels coloured by score, a pop-up with every attribute, and filters for area, zoning or flood exposure. The same data comes as a table and as GIS files for your own software.
