A site's vegetation, water bodies, habitats, and protected areas aren't just background scenery. They define what you can build, where you can build it, and what regulatory approvals stand between concept and construction. Misjudging a seasonal wetland as a dry depression can derail a project timeline by months. Missing a riparian buffer requirement can shrink your buildable area by thousands of square feet.

Objective 3.1 on the PA division tests your ability to evaluate these natural features relative to the project program. That means analyzing how vegetation communities signal soil conditions and ecological health, how water bodies create both design opportunities and regulatory constraints, how habitat classifications trigger environmental review processes, and how protected area designations limit development options.

The cognitive level here is A/E: analyze and evaluate. You won't just identify a wetland on a site plan. You'll determine whether it makes the proposed program infeasible, whether it can function as a stormwater management asset, or whether its buffer zone forces a building footprint reconfiguration. You'll weigh competing factors and make judgment calls about site feasibility.

This topic connects directly to site programming because natural feature assessment determines which portions of a site are developable, which require preservation, and which offer dual-purpose value as both amenity and infrastructure.
