When assessing a place or piece of land, it is essential first to understand the conditions of the site: the soil, water, slope/topography, vegetation, access, infrastructure, and past or current human activities and impacts.

First, gather information about your site remotely by reviewing existing soil and aerial maps, historic land uses, and current climate information. Then, walk the site during different seasons and weather conditions to collect soil samples, make observations, survey vegetation, and identify microclimates. If possible, it is best to take a full year (or more) to complete a site assessment in order to understand how the site responds during different seasons and weather events.

Collect as much data as possible and make notes about each of the following categories:

Remote

On-Site

Maps/Landform

Aerial photos
Topographical maps
Property boundaries
Local zoning bylaws

Position
Slope
Aspect

Soils

Soil type
Soil texture
Depth to the water table
Drainage class
Capability class
Farmland designation

Collect soil samples: chemical and biological assay, organic matter, pH
Comprehensive soil health assessment: compaction, bulk density, aggregate stability
