Topic: Drainage and Stormwater

Delaware is a coastal state. Most of the land in Delaware is flat and close to sea-level. Our underlying water table is generally high. As a result, drainage and the management of stormwater are important considerations in land use planning, construction, and agriculture.

Topic: Wetlands

A wetland is simply an area of land that is wet during the growing season. All true wetlands have three characteristics: typical wetland plants, wetland soils, and evidence that water is or can be at or near the surface. Our wetlands provide valuable service to Delaware. Wetlands purify our water. They provide habitat for rare and commercially important plants, fish and animals. And they protect us from flooding.
