A genuine inland four-season climate

Seaford's more inland Sussex County position brings a genuine four-season Mid-Atlantic climate, distinct from the directly coastal moderation of Delaware's beach towns.

Real, inherited storm exposure

Sussex County is named directly in this project's own Delaware state record as most susceptible to coastal storm and flooding exposure statewide, a real consideration even for Seaford's more inland position.

Real winter-storm risk

Seaford's Mid-Atlantic inland position carries real, recurring winter-storm exposure consistent with the broader regional pattern.
